Phahameng segokanyipalo nhua polyethylene: kopo

Tlaase segokanyipalo nhua polyethylene hlahisoang tswa ethylene hloekisitsoeng, 'me e le sethothetsi organometallic protrude triethylaluminum le thaethaniamo tetrachloride. Bakeng sa nhua polyethylene ho indasteri e tse ruuoang sebedisa variants ea theknoloji 'maloa tseo li fapana ka merero mofuta, le bokgoni ba melena, mekhoa bakeng sa ho hloekisa nhua polyethylene ka sethothetsi sebediswa.

thekenoloji

Hangata ka ho fetisisa e etsoang mehato e meraro ea hlahang makasineng ea: molekyler ea ethylene, tlhoekiso lona ho tloha sethothetsi le ho qetela ho omisa tshebetso. Mora susumetsang maikutlo ka tharollo ea triethylaluminum le thaethaniamo tetrachloride ka cyclohexane di a phaella ka le peterole. Halefile ho ea ho 50 C tse peli lekholong tharollo ile fuoa melena, moo tsamaiso air-mphahamisetsa ea ethylene eketsa. Susumetsang khothalletsa karolo boima ba ethylene ho nhua polyethylene molekyler.

Ho tlosa sethothetsi tswa polymer sephetho le ile tlhotliloeng theoha lihlahisoa li bole kapele 'me qhibiliha. The nhua polyethylene centrifuge hlatsoa ho tswa sethothetsi ho sebelisa methanol.

Nhua polyethylene la khatello e tlaase ka mor'a rinsing e wrung tsoa, 'me tlhokeng di a phaella ka ntho e bakeng sa ho ntlafatsa boleng. Bakeng sa hlakisoa stabilizer sebelisoa, ethylene glycol le sodium nitrophosphate, 'me ho etsa hore ho shinier, boka ba linotši e sebelisoa.

Qetellong, nhua polyethylene e tlas'a omisa le granulation. Nhua polyethylene la khatello e tlaase hlahisoang ka mokgwa wa granules le phofo.

Liphaephe entsoe ka tlaase segokanyipalo nhua polyethylene

Di sebediswa bakeng sa tlhomamiso ea litsamaiso khase, kgelelo ya leswe le metsi.

Liphaephe etsoa ke mokhoa oo e tsoelang pele extrusion. E le lintho tse bonahalang e tala bakeng sa tlhahiso ea nhua polyethylene ka granules protrudes.

Moruong linaheng tse tsoetseng pele li sebelisa lipeipi joalo hoo e batlang e tsohle tsamaiso ea.

HDPE lipeipi ha hampe ama boleng metsi, hobane mabota ka hare tsa mafome e sa thehoa le bokella letsoai matsoai.

Tlaase khatello ea nhua polyethylene o fumane kopo ka tsamaiso ea kgelelo ya leswe, kaha ke manganga ho dintho mabifi 'me ho thempereichara e phahameng.

liphaephe khase e hape ha re timetsoe 'me u se ke ua lahleheloa ke thepa tshebetso bakeng sa nako e telele.

Durability - liphaephe phahametse boleng tloha HDPE. Ba makala-ba manganga, u se ke ua bola le se ke ratoa ke mafome, u se ke ua khoa tlas'a tšusumetso ea phahameng le batang. bophelo tšebeletso ea bona e le lilemo tse mashome a 'maloa.

Nhua polyethylene High khatello e batlang e le bonolo le rekere. sepakbola hae ke batlang e le sparse tokisetso ea limolek'hule eo haholo-holo e ama segokanyipalo lona. LDPE hlahisa e mengata e fapaneng lifilimi. Ba na le e phahameng haholo quality, le ambalaji tse bonahalang molemo kgetho ke mohlomong e le ho ka fumanoa. Ho boloka ba le matlafatsang sete ya thepa le boikutlo bo loketseng ka thempereichara e ho fihlela ho likhato tse mashome a tšeletseng. litšobotsi tse ya boleng polyethylene u se ke ua fetola ka tlas'a tšusumetso ea lik'hemik'hale. O khona ho tshepahala itšehla sehlahiswa ho tloha mongobo le mouoane ea metsi.
