Ukuqalisa ukufaka umgangatho ofudumeleyo, umbuzo ophakamayo ukuba yeyiphi na i-Pipe Stop zingcono: I-Polythylene okanye iplastiki.
Impendulo ilele kwimiqathango yokusebenza komgangatho ofudumeleyo, kunye nezimvo zeengcali, amava kunye nophononongo lwabantu abasebenza phantsi kwendlela yokufudumeza kuya kunceda ukujongana nalo mbandela.
Ngokusekwe phantse kuyo yonke imibhobho yale mihla, i-polleylene ilele, kuphela ekwenzeni imibhobho yeplasitiki yentsimbi kwi-polythylene yongezwe i-theither yentsimbi eqinisekisa ukuba i-monolith yemveliso.
I-Polythylene: IiPropathi
Ngenxa ye-folecular yemolekyuli ye-polythylene ye-polleylene inamandla aphezulu
I-Polythylene i-Polythylene ibhekisa kwizinto eziphezulu zetekhnoloji kwaye kukuveliswa kwe-polymerization ye-ethylene enesakhiwo se-mesh molecular kunye ne-REX.
Ngokuphathelelene, inkqubo yokuxhaswa kukwakha amatye ongezelelweyo emolekyuli. I-polymer yokuqala inxulunyaniswa ne-chaotac kwinqanaba le-molecular kunye neemolethi zemolekyuli, zenza iGridi emithathu ye-dimestral, isakhiwo esineziphumo ezinesiphumo "sokukhumbula".
Iimveliso ze-Whorimer enye zikhethwa
Utshintsho kubungakanani kunye nobume bombhobho phantsi kwempembelelo yomthwalo emva kokususa kwabo kubuyisela imveliso kwifom yentsusa. Ngokweempawu zobuchwephesha, iRex ayiphantsi kweyona nto ininzi kwaye idlula phantsi kobomi benkonzo.
Imibhobho yePolythylene ivelisa iindlela ezi-4:
- IPeroxide yaziswa kwi-polythylene ekwenzeni izinto. Elona nani liphezulu lokucofa ngama-75%. Kwindlela yemveliso ephantsi kunye neendleko eziphezulu zemveliso, kodwa loo nto iqhubeka kakhulu kwaye ilandelana.
- Ukuphinda-phinda-ukuqhubekiswa komswakama kunye ne-silane kunye ne-catalyst kudala iPolythylene, apho iqokobhe lemveliso lingaqinile, kodwa xa i-fluid idlula, inokumelana noxinzelelo oluphezulu. Ukutsala ngama-65%.
- URech-C-Polymer uphathwa ngokuba zii-elektroni. I-Polythylene enenqanaba eliphantsi lokucofa i-55 - 60%.
- I-RH-XD-XD-Nitric Acid isetyenzisiwe. Indlela ayifane isetyenziswe.
Kwiindlela ezidwelisiweyo, umbhobho owenziwe ngokusetyenziswa kweSilane uninzi lwemfuno, lubonakaliswa yixabiso elifanelekileyo kunye neepropathi ezamkelekileyo zokusebenza.
Inqaku ngesihloko: Ukulungiswa kwe-passer esekwe kwilitha
Olona tshintsho lubalaseleyo lombhobho womgangatho ofudumeleyo ye-Polythylene ye-Polythylene yimveliso ye-haider ye-on kunye ne-XB kunye ne-XB inomqobo, ongumqobo kwi-ielyegen ye-oxlythylene.
IINGXAKI ZOKUGQIBELA ZOKUGQIBELA
Umbhobho wezinto ezinjalo unememori yemolekyuli
Imibhobho yokufudumeza eveliswa yindlela yokuphinda ifunwe kwakhona kwaye i-XB iphawuleka:
- Ukuxhathisa kwi-cinezela yehla. Kwimowudi ephezulu yoxinzelelo, ubomi beemveliso azitshintshi. I-polymer inyanzelisa uxinzelelo lwe-10.
- Imemori yemolekyuli. Xa amanzi enyuka kumbhobho, umkhenkce ophumle ububanzi bombhobho, kwaye emva kokutsala i-ice, ubungakanani bombhobho buya kwinguqulelo yoqobo, ngaphandle kokonakalisa umxholo.
- Ukunyibilika kwaye ukutshise kubushushu obuphezulu. Izinto eziza kuqunjelwa kubushushu obungaphezu kwe-150 ° C, kunye nokusebenza xa ubushushu obuvela kwi-400 ° C.
- Ukuxhathisa kwamachiza kunye nebhayoloji. Ityhubhu yePolylenene ayikho phantsi kwenkqubo yokuthuka, ayidali iimeko zokubonakala kwesikhunta kunye nokuveliswa kwentsholongwane, umbandela awunamsebenzi we-chlorine kwaye uhlala ungathathi cala kumanzi acocekileyo.
- Ukhuseleko lwendalo. Izinto ngexesha lokufudumeza azifikeleli izinto eziyingozi kwaye zibolile kwikharbon diokside kunye namanzi xa ivutha.
I-Polythylene ayikoyiki i-wobushushu iyantlukwano
- Iplastiki. Ngokugoba okuphindiweyo, imveliso ayiqhubeki kwaye ibuyise ubungakanani begorha.
- Ukusebenza. Izinto zePolymer zigcina iipropathi, zihlala zingatshintshi ubungakanani beqondo lokushisa le-Dealant ukusuka kwi-0 ukuya kwi-95 ° C, kodwa loo nto iyakwazi ukumelana nolawulo lobushushu obungqongqo.
I-tube yentsimbi yentsimbi: Iipropathi
Iinzuzo zePolythylene enxibelelene netyhubhu yentsimbi equka amacala amahlanu, nganye nganye isebenza imisebenzi ethile. I-polymeric ye-polymeric, kunye ne-polylenene ye-polyethylene iqhuba ukhuseleko kumonakali wobuchwephesha, kwaye i-sunder engaphakathi inegalelo kwi-fluid floud.
Umaleko wangaphakathi awuzange wenze imiqobo yamanzi okwangoku
Kukho iindlela ezi-2 ezinamathela phakathi kweendawo zePolymer, kwaye phakathi-i-Landler-i-Inner yi-Aluminiyam ye-Aluminiyam enika ubungqolo yoyilo lwemveliso yeplastiki yentsimbi.
Ukuthembeka kunye nokuqina ekusebenzeni kweemveliso zentsimbi zensimbi zibonisa umgangatho weeleyibhile:
- Umaleko we-aluminium wemveliso umisela amandla ayo kwaye kufanele ukuba ube lubukhulu obuyi-3 mm. Iindlela ezi-2 zokuphumela kwe-welding ye-Aluminium echaphazela amandla ombhobho, i-Laser Welling kwi-Wiant kunye ne-Ultrasonic Welding ye-BROSS isetyenziswa ngobuchwephesha. Indlela yokuvelisa ungqingiwe ibizwa ngokuba yi-wang ass, ayinasifo sokungakhathali kwaye ngokuthelekisa i-wilding i-idyasi ayivumeli ukuvuza kwiindawo ezinxulumene noko.
- I-Adhesitive isetyenzisiwe ichaza i-runder enokubakho kwiqondo lokushisa lokuphola, elichaphazela amandla ombhobho. Kumbhobho wokusika xa usebenzisa i-glue-geli ephezulu, i-gundle ilahlekile.
- Ukuthembeka kombhobho kumiselwa yimigca yepolymer, ipolymer ene-Pex kunye ne-Pe-Rt Ukuthengisa iqinisekisa amandla ombhobho, kwaye imibhobho kunye neelebheli zisetyenziswa yiPolymer esezantsi, kolu nxibelelwano, ngendoda ye-hydraulic.
Xa ukhetha umbhobho weplasitiki wentsimbi, sicinga ukuba ezi mveliso zinendlela engenamthungo ye-Wouminum ye-Aluminium, ibonelela ngokusebenza ngokukhululekileyo kwemveliso.
Ukukhetha imibhobho yomgangatho wamanzi
Zama ukukhetha izixhobo ezisemgangathweni eziphezulu
Iziphakamiso kakhulu kwaye malunga nemveliso, kwaye malunga nomenzi, kule meko isenzo senye, ukhetho lwefomula yeyona nto ibalulekileyo / imfuneko yokuqalisa ngomgangatho:
- Ukuthembeka kwe-pile kunye namandla omatshini xa kusetyenziswa iimeko ezithile, eziya kuqinisekisa ukusebenza ngokukhululekileyo kwenkqubo ngexesha lokusebenza, i.e. Umbhobho kufuneka unyamezele uxinzelelo lwe-10 bar.
- Ubomi benkonzo okanye ukuqina kokusetyenziswa komgangatho womhlaba ofudumeleyo kuxhomekeka kwinto eyenziwe kuyo imveliso. Ukusebenza kombhobho akuvumelekile kwiqondo lokushisa le-95 ° C.
- Ukuhamba ngokukhululekileyo kwimibhobho ye-pipes ye-uthotho, umphezulu wangaphakathi wombhobho kufuneka ugudile.
- Iimeko zolondolozo, iindleko zomsebenzi wokuthintela kunye novavanyo lolawulo lwenkqubo yokuqina zilungile. Funda ngakumbi malunga nemikhwa yokukhetha, jonga kule vidiyo:
Iimpawu zothelekiso lweenkqubo zokufudumeza ezinikezelwa yimarike, ukuntywila komsebenzi wokufakelwa kunye neemeko zokusebenza ziqwalaselwa emva kokuvavanya iimpawu zomgangatho. Okokugqibela kodwa, sithelekisa iindleko zeemveliso, ezenzela umsebenzi we-akhawunti, kunye nobunzima besixhobo esizimeleyo esifudumeleyo.

Iplasitiki yentsimbi iphantsi kweplastiki ethe tyaba enqamlezileyo yePolythylene
Zonke izinto ezifanayo, nguwuphi umbhobho ongcono kumhlaba ofudumeleyo: i-polythylene okanye iron. Umahluko weemveliso kwi-polyethylene ekhutshiweyo yombhobho wensimbi yensimbi kunye nongqimba lwentsimbi.
Ukuphucula i-polymer, izazinzulu kunye neengcali kwicandelo le-chemistry likwazile ukuguqula i-Polythylene ngegama eliqhelekileyo PE-rt, ekuloo ndlela i-molecular enemingxunya enamaqhina. I-polymer ayiphulukanga iipropathi zayo ngokurisayikilisha, ngokungafaniyo noBini. Iingcebiso zeengcali ekukhetheni imibhobho babona kule vidiyo:
Imibhobho evela kwi-PE-RT Polyethylene enentloko eqinileyo ye-coollant yahlula ingxolo yengxolo yokuhamba. I-polymer igqitha kakhulu i-polylethylene engavisisani i-Polythylene ejongene ne-Polythylene ejongene nengcinezelo ephezulu kunye neqondo lobushushu lesipholo, kunye nexesha lombhobho.
Enkosi kwisakhiwo semolekyuli enebhondi esitshatileyo, i-PE Storives igcina i-thermoplastic, imibhobho inokuthengiswa kwaye idlwengule ngaphandle kokuphazamisa iindawo ezonakeleyo.
Izinto ezibonakalayo zinyamezele iqabaka eliqela kunye ne-nquising ngaphandle kokutshintsha isakhiwo kunye neepropathi. Izinto ze-PE-RT ivelisa zombini iimveliso zePolymeric kunye neplastiki yensimbi.
I-Peb-Polymant Pe-rt i-Polymer kwiipropathi zayo ihlangabeza ngokupheleleyo iimfuno zomgangatho ofudumeleyo kwaye inokuthathwa njengeyona ndlela ilungileyo xa ukhetha imibhobho.
