Phapang ea Bohlokoa–UHMW khahlano le HDPE

UHMW le HDPE ke li-polymer tsa thermoplastic tse nang le ponahalo e tšoanang. Phapang ea bohlokoa pakeng tsa UHMW le HDPE ke hore UHMW e na le liketane tse telele tsa polymer tse nang le boima bo phahameng haholo ba limolek'hule athe HDPE e na le karolelano e phahameng ea matla-ho-botenya.

UHMW e emetse polyethylene e boima ba limolek'hule tse phahameng ka ho fetisisa. E boetse e emeloa ke UHMWPE. Lentsoe HDPE le emetse Polyethylene e nang le Botenya bo Holimo.

UHMW ke eng?

UHMW ke polyethylene e boima ba limolek'hule bo phahameng haholo. Ke mofuta oa polymer ea thermoplastic. Motsoako ona oa polymer o na le liketane tse telele haholo tsa polymer tse nang le boima bo phahameng ba limolek'hule (tse ka bang limilione tse 5-9 tsa amu). Ka hona, UHMW e na le bongata bo phahameng ka ho fetisisa ba limolek'hule. Leha ho le joalo, ponahalo ea motsoako ona ha e fapane le ea HDPE.

UHMW e hlahisoa ka ho polymerization ea monomer, e leng ethylene. Ho polymerization ea ethylene ho etsa sehlahisoa sa polyethylene ea motheo. Sebopeho sa UHMW se fapane haholo le sa HDPE ka lebaka la mokhoa oa tlhahiso. UHMW e hlahisoa ka boteng ba catalyst ea metallocene (HDPE e hlahisoa ka boteng ba catalyst ea Ziegler-Natta).

HDPE ke eng?

HDPE ke polyethylene e teteaneng haholo. Ke thepa ea polymer ea thermoplastic. Thepa ena e na le boima bo phahameng ha e bapisoa le mefuta e meng ea polyethylene. Bongata ba HDPE bo fanoa e le 0.95 g/cm3. Kaha tekanyo ea makala a ketane ea polymer thepa ena e tlase haholo, liketane tsa polymer li pakiloe ka thata. Sena se etsa hore HDPE e be thata 'me e fana ka khanyetso e phahameng. HDPE e ka sebetsoa tlas'a mocheso o ka bang 120°C ntle le phello efe kapa efe e kotsi. Sena se etsa hore HDPE e khone ho clavable ka bo eona.
