Cov khoom ntawm cov ntawv polyethylene uas muaj molecular hnyav heev

Polyethylene hnyav molecular siab heev (UHMW-PE) yog cov khoom siv thermoplastic engineering uas muab txhua yam zoo ntawm cov yas ua ke. Nws muaj kev tiv taus kev hnav, kev cuam tshuam, kev tiv taus tshuaj lom neeg, nws tus kheej lubrication, coefficient me me uas tiv taus kub tsawg, lub teeb yuag, nqus tau zog, tiv taus kev laus, hluav taws kub retardant, antistatic thiab lwm yam kev ua tau zoo heev, kev siv UHMW-PE phaj lining fais fab nroj tsuag, thee nroj tsuag, coking nroj tsuag thee bunker; Ore thiab lwm yam khoom silos ntawm cement nroj tsuag, hlau nroj tsuag thiab txhuas nroj tsuag; Nplej, pub, tshuaj lag luam granary, wharf hopper, thiab lwm yam, tuaj yeem tiv thaiv cov khoom nplaum, ua kom ceev ceev pub, tshem tawm qhov xwm txheej douce, txuag kev nqis peev thiab tus nqi ntawm rab phom cua, lining bulk tuav tuaj yeem zam kev nplaum hmoov rau qhov tuav thiab txo qhov puas tsuaj ntawm kev thauj khoom thiab tshem tawm cov tshuab rau bulkhead. Nrog rau kev txhim kho ntawm cov thev naus laus zis ua yas, thaj chaw siv UHMW-PE yuav dav dua.

A, siab hnav tsis kam, vim nws cov qauv molecular tshwj xeeb, hnav tsis kam yog siab dua li cov khoom yas hlau dav dav, 6.6 zaug ntawm cov hlau carbon, 5.5 zaug ntawm cov hlau tsis xeb, 27.3 zaug ntawm tooj dag, 6 zaug ntawm nylon, 5 zaug ntawm ptfe;

B, kev ua haujlwm zoo ntawm tus kheej lubrication, me me kev sib txhuam coefficient, me me ntws tsis kam, lub zog txuag;

C, lub zog cuam tshuam siab, lub zog zoo, txawm tias thaum kub tsawg, los ntawm kev cuam tshuam muaj zog yuav tsis tawg;

D, tshuaj lom neeg zoo heev corrosion tsis kam, tsis kam (tshwj tsis yog concentrated sulfuric acid, concentrated nitric acid, ob peb lub peev xwm organic) yuav luag txhua yam kua qaub, alkali, ntsev nruab nrab;

E, tsis muaj tshuaj lom, tsis muaj saj, tsis muaj exudate;

F, cov khoom hluav taws xob zoo, kev nqus dej tsawg heev;

G, zoo heev tsis kam rau kev ntxhov siab ib puag ncig, 200 npaug ntawm cov polyethylene ib txwm muaj;

H, zoo heev tsis kam rau qhov kub thiab txias, tsis brittle txawm tias ntawm -180C °.
