2.Mohala o moputsoa:Pepe ea phepelo ea metsi ea PE, peipi ea ho ntša metsi, le peipi ea mollo

Peipi ea PE blowdown: Peipi ea PE e sebelisetsoang ho fokotsa e boetse e bitsoa phala ea polyethylene e phahameng haholo, e leng HDPE ka Senyesemane.Mofuta ona oa phala hangata o sebelisoa e le phala ea boenjiniere ba masepala, e sebelisoang haholo ho: indasteri ea likhoerekhoere.Ka lebaka la ho hanyetsa ha eona, ho hanyetsa acid, ho hanyetsa kutu, ho hanyetsa mocheso o phahameng, ho hanyetsa khatello e phahameng le litšobotsi tse ling, butle-butle e nkile sebaka sa phala ea setso ea tšepe, phala ea samente le liphaephe tse ling 'marakeng, haholo-holo hobane phala e bobebe boima le ho le bonolo ho kenya le ho falla, ke khetho e ntle ka ho fetisisa ea lisebelisoa tse ncha.

Pipe ea phepelo ea metsi ea PE: Pipe ea PE bakeng sa phepelo ea metsi ke sehlahisoa se nkelang sebaka sa phala ea tšepe ea setso le phala ea metsi a nooang ea PVC.Pipe ea metsi e tlameha ho jara khatello e itseng, hangata e khetha boima bo phahameng ba molek'hule, thepa e ntle ea mochini oa PE resin, joalo ka resin ea HDPE.Resin ea LDPE e na le matla a fokolang a matla, khatello e fokolang ea khatello, ho se tsitse ho fokolang, botsitso bo fokolang ha e etsoa le ho sebetsa, le ho hokahanya ho thata, ha e tšoanelehe e le thepa ea phala ea khatello ea metsi.Leha ho le joalo, ka lebaka la index ea eona e phahameng ea bophelo bo botle, PE, haholo-holo HDPE resin, e fetohile ntho e tloaelehileng ha ho etsoa liphaephe tsa metsi a nooang.HDPE resin e na le viscosity e nyenyane ea ho qhibiliha, metsi a matle le ho sebetsa habonolo, kahoo khetho ea khetho ea eona ea ho qhibiliha e boetse e pharaletse, hangata MI pakeng tsa 0.3-3g / 10min.

3.Yellow label line: PE peipi ea khase

Pipe ea PE bakeng sa khase ke sehlahisoa sa phepelo ea tšepe ea setso le khase ea PVC.

Pipe ea khase e tlameha ho jara khatello e itseng, hangata e khetha boima bo phahameng ba limolek'hule, thepa e ntle ea mochini oa PE resin, joalo ka resin ea HDPE.Resin ea HDPE e na le matla a fokolang a matla, khatello e fokolang ea khatello, ho se tsitse ho fokolang, botsitso bo fokolang ha e etsoa, ​​​​le ho hokahanya ho thata, ha e tšoanelehe e le thepa ea phala ea khatello ea metsi.Leha ho le joalo, LDPE, haholo-holo resin ea LLDPE, e fetohile ntho e sebelisoang hangata bakeng sa pipe ea khase ka lebaka la index ea eona e phahameng ea bophelo bo botle.LDPE, LLDPE resin melt viscosity e nyane, e ntle ea metsi, e sebetsa habonolo, kahoo khetho ea khetho ea eona ea ho qhibiliha e pharaletseng, hangata MI pakeng tsa 0.3-3g / 10min.
