Ultra siab molecular hnyav polyethylene yog cov khoom siv yas engineering nrog cov khoom zoo heev. Nws muaj cov khoom nram qab no:
1. High hnav tsis kam: UHMWPE muaj kev hnav zoo heev thiab yog ib qho zoo tshaj plaws engineering plastics ntawm tag nrho cov. Nyob rau hauv ib puag ncig kev sib txhuam siab, nws hnav tsis kam yog zoo dua.
2. Kev tiv thaiv siab: UHMWPE muaj qhov cuam tshuam tsis zoo thiab yog cov khoom siv tiv thaiv zoo heev.
3. Cov tshuaj tiv thaiv siab: UHMWPE muaj cov tshuaj tiv thaiv zoo heev thiab nthuav tawm kev ruaj ntseg zoo hauv ntau cov tshuaj thiab cov kuab tshuaj.
4. Kev sib txhuam zoo heev: Kev sib txhuam coefficient ntawm UHMWPE yog qhov tsawg heev, ua rau nws siv dav hauv ntau yam kev siv tus kheej lubricating thiab tsis tshua muaj kev sib txhuam.
5. Cov rwb thaiv tsev zoo heev: UHMWPE yog cov khoom siv rwb thaiv tsev zoo siv dav hauv kev siv hluav taws xob thiab hluav taws xob.
UHMWPE cov khoom muaj ntau yam kev siv, suav nrog:
1. Engineering machinery teb: UHMWPE cov khoom siv tuaj yeem siv los ua cov ntaub ntawv hnav-tiv taus hauv ob sab phlu, coj lub log, log rims, zawv zawg rods thiab lwm yam khoom.
2. Kev kho mob thaj chaw: UHMWPE tuaj yeem siv los ua cov khoom ntawm cov pob qij txha, xws li pob qij txha pob qij txha thiab pob qij txha pob txha.
3. Lub zog hluav taws xob: UHMWPE tuaj yeem siv los ua hauv ob sab phlu rau cov kav dej, cua turbine hniav, hnub ci vaj huam sib luag, thiab lwm yam.
4. Kev ntim khoom: UHMWPE cov khoom tuaj yeem siv los ua cov ntaub thaiv npog, tiv thaiv ntxhua khaub ncaws, thiab lub thawv thauj khoom.
Txoj kev npaj ntawm UHMWPE feem ntau suav nrog yaj polymerization thiab kua polymerization. Ntawm lawv, yaj polymerization yog feem ntau siv txoj kev npaj.
Hais txog cov ntaub ntawv kev nyab xeeb ntawm UHMWPE, nws yog ib yam khoom muaj kev nyab xeeb, tab sis tseem yuav tsum tau ceev faj hauv qab no:
1. Ua tib zoo siv cov cuab yeej tiv thaiv tus kheej, xws li hnab looj tes thiab tsom iav, kom tsis txhob raug mob ntawm qhov muag thiab tawv nqaij los ntawm cov khoom siv.
Thaum ua UHMWPE cov khoom, qhov tsim nyog ntsuas cua yuav tsum tau coj los xyuas kom meej qhov cua zoo hauv qhov chaw ua haujlwm.
3. Tsis txhob cuam tshuam rau qhov kub thiab txias ib puag ncig ntev los tiv thaiv cov khoom tawg lossis deformation.
4. Tsis txhob sib cuag nrog cov tshuaj xws li muaj zog acids thiab cov hauv paus los tiv thaiv cov khoom puas.
