Polyethylene kiato High: tono

whakaputaina polyethylene kiato iti te i te ethylene e purea ana, me rite te whakakōkī organometallic protrude triethylaluminum me Titanium tetrachloride. Hoki polyethylene i roto i te ahumahi motu whakamahi rave rahi rerekē hangarau e rerekē i roto i te momo whakaaro, te kaha piere, tikanga hoki horoi polyethylene i runga i te whakakōkī whakamahia.

hangarau

Nuinga o ngā wā kawea reira i roto i toru kaupae karapīpiti o: polymerization o ethylene, tona purenga i te whakakōkī me te tukanga whakamaroke whakamutunga. I muri te whakaoho i te otinga o te triethylaluminum me Titanium tetrachloride i roto i te huriowaro e tapiritia me penehīni. Te hana ake ki te 50 C-ōrau e rua otinga i tukua ki te piere, te wahi te pūnaha rangi-hiki o te ethylene tāpiri. whakatairanga faaururaa wahi papatipu o te ethylene ki polyethylene polymerization.

Hei tango whakakōkī i i tātari i te waerau hua atu hua whāwehe me rewa. horoia te centrifuge polyethylene i te whakakōkī te whakamahi i mewaro.

Polyethylene o pēhanga iti te heke i muri i horoia atu, me taua e tapiritia he taonga mo te whakapai ake i te kounga. No te whakamārama o te stabilizer whakamahia, ethylene glycol me te konutai nitrophosphate, a ki te hanga i shinier reira, tono te waki i te.

I te pae hopea, i raro polyethylene te ki te whakamaroke, me te granulation. Polyethylene o pēhanga iti whakaputaina i roto i te puka o granules me paura.

Paipa i hanga o polyethylene kiato iti

E whakamahia ratou mo tāutanga o ngā pūnaha hau, paipa, me te wai.

Paipa hangaia e te tikanga Tangohanga tonu. Ka rite ki rauemi raw mo te hanga o te polyethylene i roto i granules protrudes.

Ōhanga whenua whakawhanakehia whakamahi taua putorino i roto i tata katoa pūnaha.

e kore e putorino HDPE pēhia ngā te kounga wai, no te mea e kore te nga taiepa ā o te waikura i hanga, ka kohia tai kohuke.

Kua kitea polyethylene pēhanga iti tono i roto i ngā pūnaha paipa, mai te mea te reira ātete ki matū riri, me te ki pāmahana teitei.

putorino Gas kore e ngaro hoki a e kore e ngaro ngā āhuatanga mahi mō te wā roa.

Mauroa - putorino kounga pai i te HDPE. He ru-ātete ratou, e kore e pirau, ka mahi i kore waikura, e kore e anganga i raro i te mana o tiketike, me pāmahana iti. Ratou ora ratonga he maha ngā tekau tau.

Polyethylene pēhanga High ngā ngohengohe, me te rapa. Tona mea he whakaritenga āhua korekore o te rāpoi ngota e matua ka pā tona kiato. LDPE hua he whānui o kiriata ngā. E ratou he kounga tiketike rawa, a ko pea rauemi tākai pai kōwhiringa ki te kia kitea. E tiakina ana te reira a paturu i te huinga o ngā āhuatanga pai noa i pāmahana ki runga, ki ono nekehanga. āhuatanga kounga o te polyethylene kore e huri i raro i te mana o ngā matū. Ko te taea ki te tutakina reliably te hua i te houku me te kohu wai ia.
