Boemo ba liphaephe tsa HDPE bo ka sebelisoa ho hlahisa liphaephe tsa khatello, tse kang liphaephe tsa metsi tse hatelitsoeng, liphaephe tsa khase ea mafura le liphaephe tse ling tsa indasteri.E ka boela ea sebelisoa bakeng sa ho etsa liphaephe tse se nang khatello tse kang lipeipi tse nang le mabota a mabeli, lipeipi tse pota-potileng lebota, lipeipi tsa silicon-core, lipeipi tsa nosetso tsa temo le lipeipi tse kopantsoeng tsa aluminiumplastics.Ho feta moo, ka extrusion e sebetsang (silane cross-linking), e ka sebelisoa bakeng sa ho hlahisa liphaephe tsa polyethylene (PEX) tsa crosslinked polyethylene (PEX) bakeng sa ho fana ka metsi a batang le a chesang.
Mephato le boleng bo tlwaelehileng
HDPE ke resin e phahameng ea kristale, e seng polar thermoplastic resin.Ponahalo ea HDPE ea pele e tšoeu ea lebese, e leng tekanyo e itseng ea translucency karolong e tšesaane.PE e na le khanyetso e ntle ho lik'hemik'hale tse ngata tsa malapeng le tsa indasteri.Mefuta e meng ea lik'hemik'hale e ka baka kutu ea lik'hemik'hale, joalo ka li-oxidants tse corrosive (concentrated nitric acid), li-hydrocarbon tse nkhang hamonate (xylene) le li-halogenated hydrocarbons (carbon tetrachloride).Polymer ha e na hygroscopic ebile e na le khanyetso e ntle ea mouoane, e ka sebelisoang molemong oa ho paka.HDPE e na le lisebelisoa tse ntle haholo tsa motlakase, haholo-holo matla a phahameng a dielectric a insulation, e le hore e tšoanelehe haholo bakeng sa terata le thapo.Litlelase tsa boima ba limolek'hule tse mahareng ho isa ho tse phahameng li na le ts'usumetso e ntle haholo mochesong oa kamore esita le mocheso o tlase ho -40F.
Litaba tse hlokang tlhokomelo ha ho sebelisoa pipe ea HDPE
1, ho beoa ha moea ka ntle, moo ho nang le khanya ea letsatsi, ho khothalletsoa ho etsa mehato ea tšireletso.
2. Pipe ea phepelo ea metsi ea HDPE e patiloeng, phala ea DN≤110 e ka kenngoa hlabula, ho beoa ha noha hanyenyane, phala ea DN≥110 ka lebaka la ho hanyetsa mobu ka ho lekaneng, e ka hanela khatello ea mocheso, ha ho hlokahale ho boloka bolelele ba liphaephe;Mariha, ha ho hlokahale ho boloka bolelele ba liphaephe.
3, ho kenya liphaephe tsa HDPE, haeba sebaka sa ts'ebetso se le senyenyane haholo (joalo ka: pipeline hantle, kaho ea siling, joalo-joalo), e lokela ho sebelisa khokahanyo ea motlakase.
4. Ha sokete ea ho qhibiliha e chesang e hokahane, mocheso oa mocheso ha oa lokela ho ba o phahameng haholo kapa o molelele haholo, 'me mocheso o lokela ho laoloa ho 210±10℃, ho seng joalo o tla baka seretse se chesang haholo se tsoang likarolong ebe se fokotsa ka hare. bophara ba metsi;Phaephe e kenang kapa motsoako oa liphaephe e lokela ho hloeka ha sokete e kenngoa, ho seng joalo e tla etsa hore sokete e khaohe 'me e lutle;Ka nako e ts'oanang, tlhokomelo e lokela ho lefshoa ho laola Angle le tataiso ea lisebelisoa tsa pipe ho qoba ho sebetsa hape.
5, mocheso o chesang o qhibilihisa butt, motlakase o hlokahala pakeng tsa 200 ~ 220V, haeba motlakase o phahame haholo, o tla etsa hore mocheso oa poleiti ea ho futhumatsa o phahame haholo, motlakase o tlase haholo, joale mochine oa butt o ke ke oa sebetsa ka mokhoa o tloaelehileng;Butt e lokela ho ikamahanya le sebopeho;ho seng joalo, sebaka sa butt ha sea lekana, matla a motsoako oa welding ha a lekana, 'me flange ha e nepahale.Ha sejana se futhumatsang se futhumala, sebopeho sa phala ha se hloekisoe, kapa sejana sa ho futhumatsa se na le litšila tse kang oli le sediment, e leng se tla etsa hore sebopeho se robehe le ho lutla.Nako ea ho futhumatsa e lokela ho laoloa hantle.Nako e khuts'oane ea ho futhumatsa le nako e sa lekaneng ea ho monya mocheso oa phala e tla etsa hore seam ea welding e be nyane haholo.Ho futhumatsa nako e telele haholo ho tla etsa hore seam sa welding se be seholo haholo mme se ka theha welding ea sebele.
