Ukukhetha ukuqeqeshwa kwangaphandle ngumsebenzi onzima. Kufanele ukuba ithembeke, inxibe-ukunganyangeki, intle, ingonakali, iqine. Kunqweneleka ukuba kufanelekile. Zonke ezi meko zanelisa i-PVC ye-PVC phantsi.
Yintoni i-pvc (vinyl) yomgangatho wethayile
Akunjalo kwakudala, olunye uhlobo lwe-PVC ivele kwimarike-vinyl thaile. Uyinto efana neLisoleum elungileyo (yiyo elinye igama - i-linoleum), kodwa itekhnoloji yemveliso yahlukile, njengefom yokukhupha. Esi sixhobo sinqunyulwe kwiinkamba okanye izikwere, inokuba kwisiseko esinamathela okanye ngaphandle kwawo. Ayinaso igama elinye - i-LVT TIILE (LWT) -ukunciphisa igama lesiNgesi i-vinyl tile. Uyilo okanye i-ART Tile ikwacacile - i-coaast yamalungelo okushicilela yenzekile kwizikwere okanye uxande.
I-PVC yesondo ye-tile ibala kakhulu
Ifomu ekhuphayo iguqukele ikhululekile kangangokuba intengiso yoyisa ngokukhawuleza. Kulula ukulingana, uqoqosho ngakumbi. Hayi kwingqondo yexabiso-liphezulu (kwinqanaba le-linoleum yeklasi yorhwebo), kwaye kwinyani yokuba ukulima kungaphantsi kwe-linoleum. Kule, kwaye ngentsebenzo esebenzayo kwaye inemfihlo yokuthandwa kwayo okukhulayo.
I-TVC yethayile yomgangatho iqulathe i-vinyl kwaye i-resin, eyongeza ukuzinza, iiplastiki, ngamanye amaxesha iifilimu (ukunika impahla ethile okanye imbonakalo ethile). Umxube ofudumeleyo ucinezelwa. Izinto ezibangelweyo zibonakaliswa ngoxinzelelo oluphezulu, kodwa zihlala ziguquguqukayo kunye neplastiki.
I-PVC TIILE iqulethe izingqala ezahlukeneyo:
- Iingceba ezimbini ezisisiseko.
- Ifilimu enephethini.
- Umaleko okhuselayo we-PVC ebonakalayo.
- I-Polly Porntierthane enganyangekiyo.
I-pvc esemgangathweni yethayile yakha
Kubunye ukuba zimbini iintlobo ze-linoleum ze-linoleum ze-linoleum kunye ne-vinyl kunye ne-ranznyl (vinyl padz). Inketho yesibini ibiza kakhulu, kodwa incinci kakhulu, kunye nokungavisisini.
Iintlobo kunye neentlobo
Ngendlela yokulala kwe-PVC kumgangatho wokuzibulala, kukho into eqhelekileyo (yokufakwa kohlobo lwesibini luyafuneka). Ukugqiba kwezinto zomgangatho wolu hlobo kunamathiselwe kwisiseko esicocekileyo. Ngale ndlela yokufakwa, umgangatho we-monolith kunye nesiseko.
Kukho i-tile enetshekhi-oomatshini kunye nokubambelela. Izinto ziqhagamshelwe kunye nezitshixo, kwaye ukungqengqa ngokwalo kufunyanwa kungahambelani nesiseko. Olu khetho lubizwa ngokuba "ngumgangatho" odadayo.
NjengeLimoleum, iithayile zePvc zomgangatho zihlelwe ngumthwalo:
- Iklasi yama-23- 31 ilungele amagumbi nenani elincinci leendwendwe. Ingabizwa ngokuba ifumaneka ekhaya. I-Lileleum ye-Lile yeli klasi yeyona iphantsi, inobungqingqwa ukuya kuthi ga kwi-2 mm kwaye ayisiyongxaki enkulu kakhulu. Kwinkokeli enjalo, akunakwenzeka ukuba isebenzise ifanitshala ngamavili.
Ukuba ufuna umgangatho olungileyo-i-vinyl tile yenye yeendlela zokhetho
- I-TVC ye-tile yemigangatho yeklasi yamagumbi angama-32-42 yenzelwe amagumbi asetyenziswa kakhulu. Ubunzima bayo ukusuka kwi-2 mm ukuya kwi-2,5 mm, ubukhulu bomaleko okhuselayo kwanele ukumelana nayiphi na ifanitshala, kubandakanya amavili. Eli klasi liphezulu lamagumbi kunye nezindlu zabucala, kwaye ubukhulu becala lomaleko kufuneka bube yi-0.3 mm (bhetele-ngcono, kodwa kuyabiza kakhulu).
- Iklasi 43 Ngaba ukunyangwa okunganyangekiyo kakhulu kunokunyamekela ukuthutha. Umda-Iworkshop kunye nezixhobo zemveliso.
Kuzo naziphi na iiklasi, ukukhetha kombala kunye nokuthungwa kubebanzi kakhulu. Kukho ukuxeliswa kwezixhobo zendalo - iinkuni, iintlobo ezahlukeneyo zelitye, njl. Uninzi luhlala luvela kwimo yoxande, kwaye ngobude obahlukeneyo bamaqela, kukho izikwere. Iingxande zihlala zenziwa "phantsi komthi", zine-gemic i-parqueet okanye yomgangatho, kodwa isikwere sihlala sifunyanwa ngexesha elinye. Baqokelela iiphaneli ezinomdla.
Xa ukhetha ngaxeshanye neklasi, kufuneka ujonge ubukhulu bokuzikhusela. Lowo ukhulu, oqinileyo uya kuba ngumkhwa. Olona khetho lufanelekileyo lwekhaya kunye namagumbi yi-3 mm ye-3 mm ye-Tile, ubukhulu bomsebenzi okhuselayo yi-0.3 mm.
Okuhle nokubi
Ezona ndawo ziphambili ze-tile ze-vinyl kumgangatho esiqokelelwayo kuhlolo lwendwendwe (kunye nemikhosi) yesigqubuthelo somgangatho. I-plubes ihambile kakhulu:
- Ufakelo olulula. I-TVC ye-PVC yomgangatho walo naluphi na uhlobo lulingana ngokulula, kwanalonto irhalelayo. Ngexesha lokukhululwa, akukho sidingo sokuphelisa yonke ifanitshala egumbini, njengoko ibeka i-limoleum. Ungashukumisa isiqingatha esinye, emva koko udlulise yonke into ukuba iqaqambe.
- Amandla aphezulu okuthoba. Uphengululo lwe-10, inye kuphela eyathi yatshixwa ukuba imingxunya emincinci ivele kumphezulu (xa ifriji ifakiwe kwaye kwindawo apho itafile yokutyela yeyo).
- Ukuqina kunye nokukhululeka kononophelo. Musa ukoyika ukuba amanzi asasaza-nge-liay ngokufanelekileyo, umgangatho ogqubuthelayo. Ungahlamba nangayiphi na indlela. Into kuphela eyaqatshelweyo kukuba i-tiles yoncedo (engeyiyo kuphela ipathethini yomthi kuphela, kodwa kwakhona ukuthungwa kwayo) kufuneka ihlanjwe xa isiqabu. Ngaphandle koko, i-clogs yothuli kwiiGrooves. Kodwa kwangaxeshanye kwaqatshelwa ukuba ukhathalelo lweethayile ze-PVC zilula kakhulu kunemilenze kunye ne-limoleum (i "
I-vinyl yomgangatho we-vile ijongeka
- Kuhle ukuhamba. I-vinyl ye-vilel yomgangatho ayityibiliki nakwimeko emanzi. Nokuba ngexesha lokubandayo, kuvakala ngathi "kushushu." Yabekwa kwigumbi lokuhlambela endaweni yeethayile ze-ceramic. Isiseko sayo kwakhona, kodwa iimvakalelo zininzi kakhulu.
- "Uzolile." Ithayile ye-PVC yomgangatho ngaphandle kokuba umhlaba ubekiwe - kanye kwisiseko, kodwa inezikhundla ezifanelekileyo zesandi. Akangomhlaba, kwigumbi elinokuhamba ngokude kakhulu, kwaye abamelwane bangakhalazi.
- Xa uwa ngamandla kunye nezinto ezinzima zendlela akukho (i-tile ye-tile).
Ngokubanzi, phantse konke ukubhengeza ngokungathandabuzekiyo ukuba i-PVC ye-PVC yomgangatho yeyona nto banokude banayo ukuza kuthi ga ngoku. Ngaphezu koko, "ngaphambili" yayilinyibiliki, iLimoleum, i-ceramic tile, umntu nepalika. Izinto ezingalunganga zahlanganiswa kwakhona. Babengengako kakhulu:
- Ukudibana kuyinto entsha, ngenxa yoko kuyinto engaqondakaliyo ukuba iza kubaphatha njani ekuhambeni kwexesha. Ingxelo endala yiminyaka emi-5 yokusebenza.
- Iithayile ze-runznyl ezineendleko ezilungileyo zokukhusela kakhulu.
- Ukudibana akusekho ngokwemvelo.
I-TVC ye-PVC yomgangatho: enye yeendlela zokukhetha ezitshitshileyo
Njengoko ubona, kuyindlela elungileyo. Ilungele nayiphi na indawo - ubuchwephesha, indawo yokuhlala, kwiimeko zokusebenza ezintsonkothileyo.
Ilele
Ngokwenyani, ukulala kwe-vinyl tile ayisiyonkqubo entsonkothileyo, kodwa ifuna ukuchaneka. Kuhlawulwa ingqalelo eyodwa ukubeka imiqolo emibini yokuqala, emva koko isekwe kubo bonke abanye. Kukwakhona umahluko kwindlela ye-vinyl vilel ye-vinyl kwiglue, ibeka izinto zokuzincama okanye ezithandekayo. Kodwa kukho iimfuno ngokubanzi. Qwalasela yonke imibuzo ngakumbi.
I-tile ye-PVC emgangathweni inokuba sisikwere
Zeziphi izixhobo ezifunekayo
Kuthatha iseti yezixhobo, kodwa bonke bangabizi kakhulu, abaninzi basefama. Ke, uya kuwafuna:
- Umgca wentsimbi yentsimbi. Kuyo, ngaphaya kwecala elingasemva, igxa amaqhekeza eeteyipi ezimbini. Kuyimfuneko ukuba "akazange ahambe." Kwaye ke itheyipu ayisiyo inamathele kakhulu, ayincanca ngothuli, i-GIS, njl.
- Izinto zokubhala zenziwe kwi-blade ethathe indawo. I-fume kufuneka ilungele kwaye ikhululekile, abaphengululi be-blade bangcono kunentsimbi, amabala ngokwakhe ahlala ixesha elide kwaye ebukhali.
- Ukuba i-limoleum yomgangatho i-Lile ikhethiwe, efunekayo kwiGlue, ufuna i-spatulad ene-spatula enezinyo elihle. Esi sixhobo sokubeka iithayile ze-ceramic aziyi kulunga - "izinyo" kufuneka libe ngonxantathu kunye nokuphakama kweemilimitha ezimbalwa. Ukuba awuyifumani le nto, thenga i-bin, ifayile kunye nee-blade zenze abo basasazekileyo - i-1-2 mm.
Iiphaneli ze-vinyl zesini kufuneka zibekwe kwiglue ekhethekileyo
- I-roulette.
- I-tepe ebanzi yamaphepha - i-5 cm, iirowu ezininzi. Iyafuneka ukuba i-vilel thaile iya kubekwa kwiglu.
- Amawele yi-bar emkhuni, avakalelwe, ikhaphethi, izibini ezithathu ze-rigid izicubu.
Kuya kuba kuhle ukuba ne-hairyer yoKwakha. Kwiindawo ezintsonkothileyo-xa ujikeleze imibhobho - i-tile ilungele ukusika xa ishushu. Ke ayinzima ngakumbi kunokusika i-limoleum yasekhaya. Kwaye unokuyifudumeza kuphela nge-hairyer yokwakha. I-tiles ye-tile inqumle, isonge umda, inqumle ngaphezulu.
Ungayisika njani iithayile ze-pvc
Nangona i-Lileleum yeTile incinci, ukunqunyulwa ngokuthe ngqo. Ukuba ufuna ukusika oko akuyi kuncipha ngomphetho we-tile, kulula ukusebenza. Sika i-blade kunye nenzame kwicala elingaphezulu, zigobe kwindawo yokusika, isahlulo eseleyo sisebenza nge-punnet ecaleni kwentambo.
I-PVC ye-tile incipha kumgangatho oqhelekileyo, emva koko iqhekeza
Ukuba i-resh ifanele igudile-yokutsala nge-tiles elandelayo, iya kuthatha umphathi kwiScotch - ukuze ingahambi. Kule meko, kuya kufuneka inciphile kuyo yonke into ukusuka kwicala elingaphezulu. Oku akwenziwanga kwaoko, kodwa ekubeni uMlawuli akazukushukuma, kuya kuba nakho ukuchitha ibala kabini okanye kathathu.
Ukulungiswa kwesiseko
Ungayibeka i-vilel thayile kumgangatho kuphela. Kubalulekile kuphela ukuba isiseko silungisiwe ngokufanelekileyo. Ifanele igudile, icocekile, yomile kwaye ilukhuni. I-thaile yomgangatho inokubekwa kwikhonkrithi, i-stred yoluphi na uhlobo, phaneur, i-DVP, i-OBP, i-GVL kunye nezinye izinto ezifanayo.
Ngomgangatho wekhonkrithi kunye ne-tie kukho intsingiselo enye. I-scred evela kwi-CPS ifunyanwa iqaqambile kwaye ingangqinelani ngokwaneleyo. Phantsi kwe-vinyl tile kungcono ukulungelelanisa umxube ohlaziyiweyo kwisiseko sokuqhekeka. Akunzima kwaye ayibizi kakhulu, kodwa umphumo uya kulunga.
Ukuphambuka okufanelekileyo xa ubeka iithayile ze-pvc - 2 mm kwimitha
Xa ibeka i-vilel thayile kumgangatho wamaplanga, ilingana nePlywood 12-16 mm ubukhulu. Ungasebenzisa i-GVL okanye i-OSP. Bonke abathengi kufuneka baqwalaselwe, imingxunya yexesha elidlulileyo. Beka udibaniso phakathi kwamashiti (ungalibali ukubeka iipleyiti kwisasazo kwaye ushiye ithungo kwi-2-3 mm-ukubuyisela ukwanda kwe-thermal). Ukubeka udibano, kungcono ukusebenzisa i-acrylic potity - i-elaleki kwaye igudileyo, kungcono ukuba ne-GLUE TIMS. Ngokubanzi, kumgangatho wokhuni akulunganga ukubeka i-tilem ezinamathela, kodwa idadayo - kunye nezitshixo zolunye uhlobo (umatshini okanye ubunamatheko). Ithuba elincinci lento yokuba kwenye indawo ukuhlangana kuya kuba kukudumba ngenxa yomehluko kubungakanani bokwandiswa kwe-shirmal.
Inqanaba lokugqibela lokulungiswa kwesiseko lifakwe umhlaba ofanelekileyo. Isiseko siya kuba somelela ngakumbi, siya kuncipha kwaye ukubanakho kwe-accerblity kuya kuyahla, kuya kubakho ukusetyenziswa kweglue.
I-fiberkboard kwi-dirintetion
Kusekubaluleke kakhulu ukuba isiseko somile. Ukufuma kwakhe ufumafu kungabi ngaphezu kwe-5%. Yilinganisa ngoncedo lwesixhobo esikhethekileyo, kodwa akukho ndawo endlwini. Ke kuya kufuneka wenze ngendalo. Sithatha i-polyethylene ngaphandle kwemingxunya kunye netephu yegreyitha. Sijijeke ngokuqinileyo nge-polythylene scotch ukuya kwisiseko (ecaleni kwemiphetho yeqela) kwaye ishiye usuku. Emva kosuku, siyayishiya kwaye songeza ngaphakathi. Ukuba akukho themba, yonke into ihamba kakuhle-umgangatho wawuphumelele ngokwaneleyo ukuqala ukubeka iithayile zePVC.
Iindlela zokubeka nokumakisha
Ukuba i-PVC yethayile ilele izakwenziwa ngezandla zawo kwaye usebenzisa "ukukhwela", ukuxelisa iinkuni, kungangcono ukuqala ngeskimu esilula - ngokufuduka. Ngendlela enjalo yokulala, kungcono ukuba ukufuduswa ngokungacwangciswanga akubonakali kumalungu. Xa usebenzisa le nkqubo, kubalulekile ukuba amalungu e-butee ahlulwe ngama-15 cm. Indlela yokulala ikwanoqoqosho - isiqwenga se-slicking ukusuka kumqolo sinokusebenza njengeplate yokuqalisa ngaphakathi Oku kulandelayo (okanye emva komntu, ukuba i-cunction isondele ukuba isondele kune-15 cm). Olunye ukhetho oluqhelekileyo lokufuduka yi-1/3 kunye ne-1/2 yeBhodi. Kule meko, umzobo uqhelekile kwaye uhlanganise ngakumbi kuma.
Elona hlobo lilula, kodwa zilungeleleneyo zokubeka iitayile ze-vinyl zomgangatho
Ngale ndlela, ubume buhlala buhlala buhleli ecaleni kodonga olude lwegumbi. Xa usebenzisa iithayile ze-pvc ezithe ngqo ze-pvc, ubume buqala ukusuka embindini. Ukuchonga indawo yebhendi yokuqala ifumana embindini wegumbi. Emva koko kuyo, phantse ezindongeni, uqhuba umgca. Kwenze ngoncedo lwentambo okanye umlawuli kunye nepensile. Lo mgca ukhokelwa ngokubeka imiqolo emibini yokuqala ye-vinyl, edibanisa imiphetho yeethayile kunye nayo. Ngenye indlela yokhosa, yonke into inzima kakhulu-kuya kufuneka ubale, zoba, kwaye akukho lula kakhulu.
I-vinyl tele glue
Iglue isebenzisa okhethekileyo - kwi-PVC yokugcwala kwe-PVC. Kukho iingoma ezimbini zeentlobo: iglu kunye nokulungiswa. Yeyiphi iglu eyaziyo yonke into, kodwa malunga nokulungiswa phakathi, okwangoku, bambalwa. Olu tshintsho lubonakaliswa yinto yokuba ayiyomisi kwimeko eqinileyo. Xa iphuma ngaphandle, into enamathelayo ishiywe kumphezulu, efana nalowo ikwiScotch. Le ndlela ilungile kuba ukungqubana kwe-glive kunokulahlwa amaxesha aliqela. Kule, ikwajongeka ngathi yindawo enamathele i-scotch. Iithayile ze-PVC ngokulungisa ngaphandle kobunzima, kwaye nakwixesha eliqinileyo (iminyaka eliqela okanye iminyaka eliqela). Kwangelo xesha, wasusa i-caided etyalwe ukulungiswa, ayizukubekho: Ukufuduka kwasemva akukhuphela. I-Dugs kuphela ukuba batsala ngaphezulu komphetho wethayile.
Ukufakwa, iitayile ze-PVC zomgangatho zisebenzisa iglue ekhethekileyo
Nokuba loluphi uhlobo lokukhetha ubumbeko oluza kukhetha. Kubalulekile ukuba wasondela kwi-PVC ye-PVC, kwaye wayengaphezulu.
Ukubeka iithayile ze-pvc kwiglue
Iglue isetyenziswa ngomaleko ogudileyo kwisiseko esomileyo nesicocekileyo ecaleni kwe-strip phantsi. Ububanzi bebhendi yeglue kukubekwa kweethayile ezimbini, ukuba zide kwaye zinqabile, ubude begumbi. Ukufaka isicelo seglu, isasazwa kwi-spatula enezinyo elihle. Akufuneki ukuba ibekho okanye i-puddle. Kuyimfuneko ukufezekisa ukusasazwa ngokufanayo. Ukuba, ngokwemiyalelo yeglue, kufuneka anike ixesha lokuya-linda. Ukuba akunjalo-ungabeka kude.
Ungasifaka njani imbethe
Umqolo wokuqala ubeka ukulungisa umphetho omnye ngaphezulu komgca otyunjiweyo. Xa usenza iGlue, zama ukungayiyiliti, kungenjalo ungahamba gwenxa. Beka i-tile yokuqala, yatshintsha izandla, ukhalela umoya phantsi kwento. Singena ezinyaweni kwi-tile ebiyibethe, faka oku kulandelayo, uhlengahlengiso ngokuqinileyo. Ilitha iqhekeza leteyiphu epeyintiweyo kunye nobude be-latch enobude obuyi-10 cm. Kwithayile yeglue ukuya kwisiqingatha, batsala ngokuqinileyo kwi-scotch. Ke i-tile ayinalo ithuba lokuhamba. Ukuyilungisa, ukubetha, ukukhaba umoya. Siphindaphinda oku kulandelayo. Xa ibeka umqolo wesibini, usalungisa amacala usebenzisa i-3 scotch strips.
Ukubeka i-vinyl tile kumgangatho kwiglue
Ngokumisela imiqolo emibini, sithatha ibar enamava kwaye sinxiba kakuhle. Ke siqhuba umoya ngokupheleleyo. Ngokwe-tekhnoloji, kuyimfuneko ukusebenzisa i-roller evuthayo enobunzima obungama-50 kg, ojijelweyo. Ekhaya, akunjalo, kuya kufuneka itshintshwe. Ikho enye indlela yokugcoba ngobumnene i-linoleum tile: emva kokubeka kulungile ukubamba umfanekiso werabha.
Emva koko, imiqolo emibini ibekwe kwelinye icala lomtya. Emva koku-odola ukubekwa akusekho kubaluleke kakhulu, kodwa kunqweneleka kakhulu ukususa umoya ngenye yeendlela.
Oku kujongeka ngathi yi-roller roller
Kutheni ufuna ukulungiswa ngeScotch, kuba kunqabile ukuyisebenzisa? Ukuze itayile esele igqityiwe, kwaye oku kunokwenzeka, kuba ixesha lokumisa ngokupheleleyo kweglue ziiyure ezingama-72.
Kwisiseko sokuzithemba
I-TVC yokuzincama kwe-PVC emgangathweni nayo ikhuselwe. Umahluko kukuba awudingi ukuba ufake i-glue. Ngaphambi kokufaka i-tile, susa umaleko okhuselayo, faka i-tile endaweni, egudileyo. Yonke le nkqubo iyafana.
I-stack kwi-stasive
Kule meko, iiplanga azinakurekhodwa yi-scotch, kuba into ekwindawo ebandakanya icala inamathele ngokwaneleyo ukugcina i-shift evela kwangoko emva kokunamathela kwangoko emva kokunamathela kwangoko emva kokunamathela kwangoko emva kokunamathela kwangoko emva kokunamathela kwangoko emva kokunamathela kwangoko emva kokunamathela. Ingxaki ebalulekileyo kukucinezela iithayile kuqala kumphezulu wecala, ubambe i-bar kubunzima. Xa umphetho udongwe, ngokuthe ngcembe wahlikihla uhambo, ukuzama ukuhlala njengomoya ombalwa kangangoko kunokwenzeka.
Ukubeka iithayile ze-pvc ngetshixa
Itshixa kwi-vilel tile i-maneral kunye nembethe. Umahluko kuphela kumgaqo wokulungiswa. Imigaqo eseleyo iyafana.
Umahluko ophambili kukubekwa kwetshiphu i-vinyl iqala eludongeni. Iiplanga zikwindawo yokuba izitshixo "zibukele" kwigumbi. Umqolo wokuqala ubambelele kwiimilimitha ezininzi ukusuka eludongeni - ukubuyisela ulwando lwe-thermal. Lo msantsa unokuqinisekiswa ngokuseta isiqwenga sezinto ezinobungqingqwa okanye ukufumana imivalo emgceni yethayile.
Ungayibeka njani i-piles ze-pvc ngoomatshini bokutshixa
Xa ibeka iithayile ze-PVC ngokuvalelwa okunamathela, kufuneka uqale uneentloni ukuphela, ukudibanisa imiphetho ye-Ski. Emva koko baqhagamshela isitshixo kwicala elide kwaye, kuphela emva koko, iiplanga ziphulukene ngokupheleleyo. Imiphetho i-strooke, ejonge uxinzelelo lokungena kwe-cock ye-cock.
Le vidiyo ilandelayo ibonisa ukuba i-PVC Tile ye-PVC phantsi kwe-cock yomatshini iyaboniswa. Ngokwesiqhelo, imiyalelo enemifanekiso iya kwizixhobo, kodwa ikwaluncedo kakhulu.
Inkqubo yokubeka i-vilel ye-vinyl enetshiphu yokuzivalela iyaboniswa kule vidiyo. Unxibelelwano alunakuthenjwa, kwaye kulula ukudibana nokudibana.
