Phapang ea Sehloho-UHMW vs HDPE

UHMW le HDPE ke lipolima tsa thermoplastic tse nang le chebahalo e tšoanang.Phapang ea bohlokoa lipakeng tsa UHMW le HDPE ke hore UHMW e na le liketane tse telele tsa polymer tse nang le boima ba limolek'hule tse phahameng haholo athe HDPE e na le karo-karolelano e phahameng ea matla ho isa ho sekhahla.

UHMW e emetse Ultra High Molecular Weight polyethylene.E boetse e hlalosoa ke UHMWPE.Lentsoe HDPE le emetse High Density Polyethylene.

UHMW ke eng?

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

Liketane tsohle tsa polymer ho UHMW li telele haholo, 'me li hokahana ka nqa e le 'ngoe.Ketane e 'ngoe le e' ngoe ea polymer e hokahane le liketane tse ling tse potolohileng polymer ka mabotho a Van der Waal.Sena se etsa hore sebopeho sohle se be thata haholo.

UHMW e hlahisoa ho tsoa ho polymerization ea monoma, ethylene.Polymerization ea ethylene e theha sehlahisoa sa motheo sa polyethylene.Sebopeho sa UHMW se fapane haholo le sa HDPE ka lebaka la mokhoa oa tlhahiso.UHMW e hlahisoa boteng ba metallocene catalyst (HDPE e hlahisoa ka pel'a Ziegler-Natta catalyst).

HDPE ke eng?

HDPE ke polyethylene ea boleng bo phahameng.Ke thepa ea thermoplastic polymer.Boitsebiso bona bo na le sekhahla se phahameng ha se bapisoa le mefuta e meng ea polyethylene.Boima ba HDPE bo fanoa e le 0.95 g/cm3.Kaha tekanyo ea lekala la polymer chain ho thepa ena e tlase haholo, liketane tsa polymer li pakiloe ka thata.Sena se etsa hore HDPE e be thata ebile e fana ka khanyetso e matla.HDPE e ka sebetsanoa tlas'a mocheso o ka bang 120°C ntle le phello efe kapa efe e kotsi.Sena se etsa hore HDPE e khonehe.

Ho Tšoana Hofe Pakeng tsa UHMW le HDPE?

UHMW le HDPE li entsoe ka ethylene monomers.

Ka bobeli ke li-polymer tsa thermoplastic.

Ka bobeli UHMW le HDPE li entsoe ka ethylene monomers ka polymerization.Phapang ea bohlokoa lipakeng tsa UHMW le HDPE ke hore UHMW e na le liketane tse telele tsa polymer tse nang le boima ba limolek'hule tse phahameng haholo athe HDPE e na le karo-karolelano e phahameng ea matla ho isa ho sekhahla.
