UHMWPE bụ okwu mkpọ okwu nke Ultra High Molecular Weight PolyEthylene
UHMWPE bụ eriri ahịrị, obere nrụgide, ụdị Ziegler-catalyst, resin polyethylene.
Okwu
UHMWPE nwere oke molekụla dị arọ nke dị oke arọ, ihe dịka okpukpu iri karịa nke ịdị arọ molekụla dị elu, resins polyethylene dị elu (HDPE).
N'ihi njupụta molekụla ya dị elu, UHMWPE nwere ma nguzogide abrasion kachasị elu yana ike mmetụta kachasị elu nke plastik ọ bụla.
N'ezie, 25mm (1 ″) oke ụra nwere ike ịkwụsị slug pistol caliber 0.38 na 150 mm (6 ″).
UHMWPE bụ polymer linear ndabere (PE) nwere ihe pụrụ iche.
UHMWPE nwere ike mmetụta kachasị elu n'etiti ndị polymer injinịa ndị ọzọ yana oke abrasion na iyi nguzogide, biocompatibility, nguzogide mkpọtụ, obere esemokwu nke esemokwu, ezigbo nguzogide kemịkalụ na nguzogide eletriki.
Ejikọtara ya na nguzogide abrasion na ike siri ike, ọnụ ọgụgụ dị ala nke esemokwu nke UHMWPE na-enye onwe ya mmanu, elu na-adịghị mma.
Ọnụọgụ static na ike siri ike dị obere karịa ígwè na ọtụtụ ihe plastik.
UHMWPE nwere ike rụọ ọrụ dị ka biomaterial, karịsịa dị ka na ngụkọta nkwonkwo ndochi components dị ka ọmụmaatụ hip prosthesis ma ọ bụ ihe ọ bụla nkwonkwo nnọchi ịwa ahụ.
Ngwa ndị emere site na UHMWPE na-edobe ibu dị mgbagwoju anya karịa ogologo oge.
UHMWPE nwere nnukwu viscosity ọbụna karịa okpomọkụ agbaze.
Ya mere, ọ na-esiri ike ịhazi UHMWPE dị ọcha site n'ịkpụzi injection, ịkpụzi ihe, ma ọ bụ extrusion nke a na-ahụkarị.
Otú ọ dị, ibelata viscosity site na mgbakwunye nke obere yinye oligomers nwere ike imetụta njirimara nke ngwaahịa.
Ike nhazi adịghị mma na-egbochi nnukwu ngwa UHMWPE dị ugbu a.
Iji mee ka nhazi ya dị mfe maka ngwa ngwa, UHMWPE jikọtara ya na polyethylene (PE), polypropylene (PP), polyacrylate (PA), polycarbonate (PC), polyaniline (PANI), na ihe ndị ọzọ iji meziwanye ihe ndị dị otú ahụ polymers.
A na-eji polyethylene dị elu (HDPE) mee ihe n'ọtụtụ ebe na ụlọ ọrụ n'ihi nhazi dị mma, ihe ndị a chọrọ na ọnụ ala dị ala.
Ngwakọta UHMWPE/HDPE dọtara uche dị ukwuu dị ka ihe ndozi nkwonkwo mmadụ na-ekwe nkwa n'ihi na ngwakọta dị otú ahụ nwere nguzogide dị mma karịa UHMWPE dị mma.
Ọzọkwa, HDPE bụkwa polymer na-arụkọ ọrụ ọnụ yana ọnụnọ HDPE nwere ike melite nhazi nke ngwakọta UHMWPE.
A mụọla ọtụtụ ihe nke ngwakọta UHMWPE/HDPE, dị ka nhazi nhazi, akụrụngwa rheological, thermal oxidative Njirimara na mmetụta mmetụta.
Ọ bụrụ na amachaghị UHMWPE na mpụga otu ndị ọkachamara, ngwa ya amaara nke ọma na ngalaba ụlọ ọrụ, biomedical na nchekwa.
