5 lab tus pas nrig UHMWPE uas muaj molecular hnyav
Kev piav qhia:
Cov pas nrig siab heev uas peb lub tuam txhab tsim tawm muaj kev tiv taus zoo heev, tiv taus qhov kub thiab txias qis, ua rau nws tus kheej lubricating, tsis muaj tshuaj lom, tiv taus dej thiab tiv taus tshuaj lom neeg. Cov khoom siv kho tshuab siab heev. Nws muaj kev tiv taus kev cuam tshuam zoo heev, tiv taus kev tawg, tiv taus kub siab, tsis sib txhuam, ua rau nws tus kheej lubrication, tiv taus tshuaj lom neeg zoo heev, tiv taus qaug zog, suab nrov nrov, tiv taus hluav taws xob nuclear. Nws tuaj yeem hloov cov hlau carbon, hlau tsis xeb, tooj liab thiab lwm yam khoom siv rau textile, papermaking, tshuab zaub mov, kev thauj mus los, kev kho mob, kev khawb thee, kev lag luam tshuaj lom neeg thiab lwm yam lag luam.
Cov khoom txheem:
| Txoj kab uas hla (hli) | 15-200 hli |
| Ntev | 1000 hli/daim |
| Xim | feem ntau dawb thiab dub, lwm yam xim tuaj yeem hloov kho raws li cov neeg siv khoom. |
| Vaj tse | tuaj yeem hloov kho tau hluav taws kub retardant, antistatic, high-strength, high lubrication thiab lwm yam khoom |
Kev Taw Qhia UHMWPE:
Polyethylene hnyav molecular siab heev (UHMW-PE) yog hais txog polyethylene linear nrog qhov nruab nrab molecular hnyav ntau dua 1.5 lab. Vim nws qhov hnyav molecular siab heev (polyethylene ib txwm muaj 20,000 txog 300,000), UHMW-PE muaj kev ua tau zoo tsis sib xws piv rau polyethylene ib txwm thiab lwm yam yas engineering:
1) Kev tiv thaiv kev hnav siab heev, siab dua nylon 66 thiab PTFE 4 npaug, siab dua carbon hlau 6 npaug, qhov zoo tshaj plaws ntawm txhua cov khoom siv hluavtaws tam sim no.
2) Lub zog cuam tshuam siab heev, uas yog 2 npaug ntawm polycarbonate thiab 5 npaug ntawm ABS, thiab tuaj yeem tswj tau qhov muaj zog siab ntawm qhov kub ntawm cov kua nitrogen (-196 ℃).
3) Cov khoom siv zoo rau tus kheej, nws cov khoom siv lubricating zoo ib yam li PTFE, thiab qhov sib txhuam coefficient tsuas yog 0.07-0.11; nws tsuas yog 1/4-1/3 ntawm qhov sib txhuam coefficient ntawm hlau.
4) Tus nqi nqus hluav taws xob poob siab yog qhov siab tshaj plaws ntawm txhua yam yas, thiab qhov cuam tshuam txo suab nrov zoo heev.
5) Nws muaj kev ruaj khov tshuaj lom neeg siab thiab tuaj yeem tiv taus ntau yam corrosive media thiab organic media hauv qee qhov kub thiab txias thiab concentration.
6) Muaj peev xwm tiv thaiv kev nplaum, thib ob tsuas yog "Yas Vaj Ntxwv" PTFE.
7) Huv si thiab tsis muaj tshuaj lom, nws tuaj yeem siv rau hauv kev sib cuag nrog zaub mov thiab tshuaj.
8) Qhov ceev yog qhov tsawg tshaj plaws ntawm txhua yam yas engineering, 56% sib dua li PTFE thiab 22% sib dua li polycarbonate; qhov ceev yog 1/8 ntawm cov hlau, thiab lwm yam.
Vim yog qhov kev ua tau zoo tshaj plaws saum toj no, UHMW-PE raug hu ua "yas zoo kawg nkaus" los ntawm cov tebchaws European thiab Asmeskas thiab tau txais txiaj ntsig thiab siv dav hauv ntau yam lag luam.
