UHMWPE Inkcazo kunye namagqabantshintshi

Ingcaciso

I-UHMWPE sisishunqulelo se-Ultra High Molecular Weight PolyEthylene

I-UHMWPE i-linear, i-low-pressure, i-Ziegler-type-catalyst, i-polyethylene resin.

Amagqabantshintshi

I-UHMWPE inobunzima obugqithisileyo obuyi-avareji yemolekyuli, malunga nokuphinda-phindwe kashumi kobobunzima bemolekyuli, i-High density polyethylene (HDPE) resins.

Ngenxa yoxinaniso lwemolekyuli ephezulu kakhulu, i-UHMWPE inezona ndawo ziphezulu zokuxhathisa ukuqhawuka kunye namandla eempembelelo zeplastiki.

Enyanisweni, i-25mm (1″) yempama engqindilili inokumisa i-0.38 caliber pistol slug kwi-150 mm (6″).

I-UHMWPE yimvelaphi elula yomgca (PE) iipholima ezineempawu ezizodwa.

I-UHMWPE inamandla amakhulu empembelelo phakathi kwezinye iipolima zobunjineli kunye nokugruzuka okugqwesileyo kunye nokunganyangeki kokunxiba, ukuhambelana kwezinto eziphilayo, ukuxhathisa ingxolo, ukulingana okuphantsi kakhulu kokungqubana, ukuchasana kakuhle kweekhemikhali kunye nokuxhathisa ukufakwa kombane.

Idityaniswe nokuxhathisa kwe-abrasion kunye nokuqina, i-coefficient ephantsi ye-friction ye-UHMWPE ivelisa i-self-lubricating, non-stick surface.

I-Static kunye ne-dynamic coefficients iphantsi kakhulu kunentsimbi kunye nezixhobo ezininzi zeplastiki.

I-UHMWPE inokusebenza njenge-biomaterial, ngakumbi njengakumalungu apheleleyo okubuyisela amalungu njengomzekelo we-hip prosthesis okanye naluphi na utyando lokubuyisela ilungu.

Amacandelo enziwe kwi-UHMWPE axhomekeke kumthwalo onzima ngexesha elongeziweyo.

I-UHMWPE ine-viscosity ephezulu nangaphezulu kobushushu obunyibilikayo.

Ke, kunzima ukwenza i-UHMWPE esulungekileyo ngokubumba inaliti, ukubumba ukuvuthela, okanye i-screw extrusion eqhelekileyo.

Nangona kunjalo, ukunciphisa i-viscosity ngokongezwa kwe-oligomers yekhonkco elifutshane kunokuchaphazela iipropati zeemveliso.

Ukuqhubekeka okulambathayo kunqanda izicelo ezininzi ezikhoyo ze-UHMWPE.

Ukuququzelela ukuqhutyelwa kwayo kwezicelo, i-UHMWPE idibene ne-polyethylene (PE), i-polypropylene (PP), i-polyacrylate (PA), i-polycarbonate (i-PC), i-polyaniline (i-PANI), kunye nezinye izinto zokuphucula iimpawu ze-polymers ezinjalo.

I-Polyethylene yoxinaniso oluphezulu (HDPE) isetyenziswe ngokubanzi kwishishini ngenxa yokuqhuba kakuhle, iipropati ezinqwenelekayo kunye neendleko eziphantsi.

Umdibaniso we-UHMWPE/HDPE utsale ingqwalasela enkulu njengento ethembisayo yokulungisa okudityaniswayo kwabantu kuba umxube onjalo unokuxhathisa okuhamba kakuhle kune-UHMWPE ecocekileyo.

Ngaphaya koko, i-HDPE ikwayipolymer ehambelana nebhayoloji kwaye ubukho beHDPE bunokuphucula ukuqhubekeka komxube we-UHMWPE.

Iipropati ezininzi zomxube we-UHMWPE/HDPE ziye zafundwa, ezifana nokusebenza kokusebenza, iimpawu ze-rheological, iipropati ze-oxidative ze-thermal kunye nokuziphatha kwempembelelo.

Ukuba i-UHMWPE ayaziwa kangako ngaphandle kwesangqa seengcaphephe, izicelo zayo zaziwa kakhulu kushishino, kumacandelo ezonyango kunye nokhuseleko.
