Ukufakwa kwanamuhla kwezindonga kumelwe "izinkambiso" zokwakha njengoboya bezimbiwa ezinezici ezahlukahlukene ekwakhiweni kwezakhiwo ezihlukile, namapuleti we-polyfoam ahlukaniswe phakathi kokufakelwa. Zombili lezi zinketho ziyizinto ezinhle kakhulu zokufaka izindonga. Kepha kukhona ukuntuleka kwabo, bayabiza, futhi inqubo yokufakwa kwabo iyinkimbinkimbi yezobuchwepheshe, ukuthi ngabe leli cala liyimpungushe yokufakelwa kwezindonga, linezici ezicishe zilingene futhi ngasikhathi sinye zilula, Futhi intengo ibiza kakhulu.
Vele, izindleko ze-foam uqobo zingaxhunyaniswa esidlekeni sokusebenzisa imishini ekhethekile yamagwebu adinga ukusetshenziswa lapho esebenza ngezindawo ezinkulu zaphezulu ziphathwa. Kepha, ngisho nokubheka lokhu, intengo iyaqondaniswa, kepha kube lula ukusebenzisa lolu hlobo lokufakelwa okushisayo kusele.
Ngaphezu kokusebenziseka lula kokufaka isicelo, ukufakwa kwegwebu kunezinzuzo eziningi eziningi, okuyisici sohlobo ngalunye lokufakelwa okucatshangelwe. Ake sizungeze ngamunye wabo, bese sithola ukuthi yini igwebu lokufakelwa kwezindonga.
Izinhlobo ze-Foam nezinzuzo zazo
Izinzuzo ezabiwe ngohlobo ngalunye lokufakelwa kwegwebu:
- Ukufakwa kwe-thermal kwesinye isikhathi kunezikhathi eziyishumi ngaphezu kwezinkomba zoboya bezimbiwa kanye negwebu, okufanayo kusebenza ezimweni zokutholwa komsindo;
- I-Foam inamathela kunoma iyiphi impahla "ngokuqinile", izisekelo zangaphezulu futhi impahla yayo cishe ayinandaba, okuhlukile ngaphandle kwe-polyethylene;
- Lokhu kufakelwa kucishe kwaphakade. Ngobuchwepheshe obufanele bohlelo lokusebenza, iminyaka eminingi ingasebenza ngaphandle kwesidingo sokushintsha;
- Imvelo. Ngemuva kokuqina, lokho okubonakalayo akuvezi noma yiziphi izakhi eziyingozi emoyeni ezingalimaza impilo yabantu;
- Uvikela insimbi kwi-oxidation, ngenxa yokubekwa uphawu okuphelele kobuso;
- Uma usebenzisa ukufakwa kwamagwebu ngezindawo zokhuni, zizovikela ngokuvela kwesikhunta futhi zivikele ukubola;
- Ingasetshenziswa futhi isetshenziswe ngamazinga okushisa aphansi kakhulu futhi aphezulu.
Ngezinzuzo ezitholakele ngaphandle, kepha akunakuba yini ukuthi akukho ziphutha? Kulungile, akunakwenzeka. Ngokwami, kuphela ukuntuleka kokufakwa kwamagwebu okufika engqondweni, lokhu ukubekezelela okubi kwe-ultraviolet. Ngaphansi kokuthonya kwethonya layo, okokuqala kushintsha umbala kusuka kuphuzi kuya ku-orange ekhanyayo, bese kubhujiswa ngokuphelele. Ukuyivimba, lokho okuqukethwe kumele kuhlukaniswe elangeni eliqondile.
Isihloko ngesihloko: Itheyiphu yokuhlobisa yamakhethini: Ungayithunga kanjani
Futhi, ukufakwa ngemuva kokuqina kudinga ukuvikeleka kumswakama kusuka ekungeneni, njengoba amagwebu awo amunca kahle. Ngegama, ukufakwa kwegwebu akunakushiywa kungambulwa, kudinga ukucwazimula okwengeziwe.
Ngokusho kokwakheka kwe-foam, kuyinto eyodwa nengxenye ezimbili futhi ihlukaniswe ngezinhlobo ezintathu eziphambili:
- Umhlangano;
- Foamizole;
- Polyurethane.
Engele
Ukufakelwa kwezindonga nge-Foam yomhlangano kukhiqizwa ezindaweni ezincane, njengoba kungenanjongo nakwezomnotho ukuyisebenzisa ezindaweni ezinkulu. Konke ngoba i-foam ebendayo ithengiswa ngenani elilinganiselwe kuma-cylinders angama-200, 350 no-750 ml. Enye ngisho nebhaluni elikhulu kunawo wonke alibizi, kepha likubamba kuphela ngemitha elilodwa. m. Indawo engafakwanga, inqobo nje uma ubukhulu obude bufinyelela kumasentimitha ayi-8.
Udonga olufakwe nge-foam ekhuphukayo lunokufakwa okushisayo okuphansi kakhulu kunalapho usebenzisa i-foamizole ne-polyurethane foam, njengoba lokhu kufakwa kwamangqamuzana okuvaliwe nama-flower, lapho i-polyurethane insulation ingazigabisa ama-pores angama-90%.
Ukugcwala kwe-foam ekhuphukayo kwenzeka ngenxa yokuhlinzekwa kwaso ebusweni ngaphansi kwengcindezi, futhi ngenxa yokusabela ngomswakama, okuqukethwe emoyeni. Faka i-foam ekhuphukayo ikakhulukazi yokuvalwa uphawu, imithambeka kumafreyimu wewindows nalapho ufaka iminyango yensimbi-yepulasitiki. Ukufakelwa kodonga kungafakwa futhi kufakwe ku-insud, kepha kuphela uma indawo incane, ngokwesibonelo, kuvulandi noma i-loggia.
Isithunzi
Lokhu kuhlanganiswa sekuvele kuyinkimbinkimbi ngokwengeziwe ngokufaka igwebu. Kuyatholakala, okuxakayo ngokwanele, ngesimo samapuleti, futhi njengegwebu elivamile, kepha akunjalo. Esimweni se-liquid, lokhu okuqukethwe sekulethwa ngqo esizeni lapho kwenziwa khona umsebenzi. Lokhu kwenziwa kusetshenziswa imoto ekhethekile, engaphansi kwengcindezi incibilikisa lokho futhi ayixube ne-resin.
Ukufakwa kodonga nge-foamizol kwenziwa ngokuyisebenzisa ebusweni ngesibhamu sokwakha. I-Foaming yenzeka esevele ingaphakathi emotweni, ngemuva kokusebenzisa udonga lukhuni imizuzu engu-15, isithwathwa esigcwele senzeka ngezinsuku ezimbili kuya kwezintathu. Lokwakheka kuzokuphefumula ngokushesha uma i-resin ingafakiwe kukho.
Isihloko ngesihloko: Ukugeza okuvinjelwe: Kubiza malini?
Ngenxa yokomiswa isikhathi eside, kusetshenziselwa ikakhulukazi ukufakwa komsebenzi wezitini, kanye nokwakhiwa kokushisa okufaka ungqimba ngokugcwalisa ifomu ngomgodi okhethekile. Ukufakwa kodonga nge-foamizole kusetshenziswa kabanzi ezindlini zozimele.
Ukwakheka kwalolu Foam wokufaka okushisayo kufaka ama-carbamides nama-formaldehydes. Ngenxa yalokhu, abaningi bakholelwa ukuthi lokhu okuqukethwe kuhlukaniswa ngezinto eziyingozi ngemuva kweqhwa ngemuva kweqhwa. Ngimemezele ngokungezelela, lokhu akunjalo, le nto yempahla yama-formaldehydes ekwakheni i-foam imisiwe ngokuphelele futhi ayiba yingozi empilweni yabantu.
Polyurethan
I-Polyurethane Foam yokufakelwa kodonga yinto yokufaka okushisayo kokufakwa kochwepheshe. Njengoba inengxenye emibili futhi iqukethe i-isocionate ne-polylol. I-Foaming yenzeka ngenxa nje yokusabela kwalezi zinto ezimbili. Udonga ngaphambi kokufaka isicelo sokufakwa kwe-Foam Thermal cishe akudingi ukulungiselela, udinga kuphela ukuwakhipha kahle inani le-Foam elisetshenzisiwe.
Kulula ukukwenza uma usebenzisa isakhiwo esikhethekile se-pulverizer nomshini ongahlinzekwa ngaphansi kwengcindezi esiqeshini esiqediwe esodongeni. Ngemuva kokufaka isicelo, i-polyurethane Foam iqhwa ngaphakathi kwemizuzu embalwa, yanda ngevolumu ngama-40, futhi ngisho nezikhathi eziyi-120, igcwalisa yonke indawo etholakalayo, ngisho nasezindaweni ezinzima kakhulu. Ukufakwa kwe-Dana Thermal kulungele ukusetshenziswa ezindaweni ezinkulu ngenxa yokunwetshwa okuphezulu nokugcwaliswa.
Lapho usebenza ngezindonga ezinkulu, khumbula ukuthi ukusebenzisa i-polyurethane Foam, kulokhu kulandela izingqimba eziningana. Uma wenza konke ngongqimba olulodwa, amagwebu angalala ngokungafanele, futhi ngenxa yengcindezi enkulu angaphula noma yimuphi umklamo wokwakha, ngokwesibonelo, uhlaka.
Ukugcwalisa Foam - Ukufundiswa
Ngobukhulu, ubeka izindonga zegwebu kusuka ngaphakathi kulula, kepha kunezikhathi zokunaka. Okokuqala, lokhu ukuphepha komsebenzi. Noma ngabe uluphi uhlobo lwegwebu olungelona umxhwele, kufanele uvalwe esutsheni elivikelayo kusuka ku-polyethylene, ngoba kuphela kulokhu okuqukethwe, igwebu alinamatheli.
Isihloko ngesihloko: Ukwenza kanjani abamba ukushisa: Imiklamo engu-8 nemibono yasolwandle
Imvunulo kufanele ibe ne-hood, ngoba, uma ikhambi liwela ezinweleni, kuzofanele zisikwe. Futhi kufakwe amagilavu, izibuko kanye nokuphefumula, ukuvikela izandla, amehlo kanye nepheshana lokuphefumula, ngokulandelana.
I-respirator iyadingeka, ngoba lapho unwebisa futhi ukhulula igwebu, igesi ihlukaniswa, okungafanele iphefumule uma ungafuni ukuthola izinkinga zempilo, ngaphezu kwalokho, izinhlayiya ezincane zezinto ezibonakalayo zingaba khona emoyeni.
Iphuzu lesibili lihlobene nendlela yokufaka igwebu phakathi kwemingcele yendawo efakiwe, ingasebenza njengezindonga ezimbili kanye nohlaka olukhethekile oluhlukanisa udonga ezikhungweni. Izindlela zimbili, ngosizo lwe-pistol yokwakha kanye nesifutho sengcindezi. Inketho yesibili, njengoba kungenzeka ukuthi uqagela ukukhathazeka ukusetshenziswa kwe-foam ekhuphukayo.
Lapho usebenzisa isibhamu sokwakha, udinga ukukhokhisa ukwakheka okufisayo kwegwebu, i-polyurethane noma igwebu, bese usebenzisa ungqimba oluyunifomu odongeni. Udonga lufakelwa, kufanele lukhuphuke kusuka phansi, kuzoba lula kakhulu ukulawula ukuphela kwesikhala. Ngokomphumela, udonga kufanele lwakha uhlobo lwejazi le-foam ngendawo encane ebekiwe.
Ukusebenza ne-Foam ekhuphukayo, udinga ukukhumbula ukuthi isilinda sidinga ukugcina phansi ngokuqinile futhi singavumeli ukufudumala kwaso ngenhla kwama-degrees angu-2, ngaphandle kwalokho kungenzeki ukukuvikela isudi evikelayo.
Okwesithathu kuphathelene nobukhulu bengqimba esetshenzisiwe. Uma usayizi wokufakwa udlula u-8 cm ngobukhulu, isicelo sawo kumele sihlukaniswe izingxenye. Ungqimba ngamunye we-foam kufanele lome ngokuphelele ngaphambi kokuthi kusetshenziswe olandelayo. Imvamisa, nge-flow floorwing the Foam oyidingayo kuze kube amahora angama-24.
Njengoba kushiwo ngaphambili, igwebu kufanele lisetshenziswe ezingxenyeni eziningana, ngenxa yokuthi ingcindezi ebiyelwe ukufakwa ngesikhathi sokunwetshwa kungenzeka iphule isakhiwo sohlaka, noma ngabe senziwa ngokhuni noma kusuka kuphrofayili ye-aluminium.
Ividiyo ethi "Polyurethan. Ukufafaza bese ugcwalisa »
Ividiyo ikhombisa ngokusobala umphumela we-polyurethane Foam lapho isetshenziswa ebusweni. Kungabonakala ngeso elinqunu, njengoba linwebeka futhi ligcwalisa yonke indawo edingekayo.
