3. ABS (acrylonitrile-butadiene-styrene copolymer):
(1) Cov yam ntxwv: ABS yog cov khoom siv thermoplastic polymer nrog lub zog siab, zoo toughness thiab ua haujlwm yooj yim. Nws muaj qhov zoo ntawm acrylonitrile, butadiene thiab styrene peb monomers, yog li nws muaj tshuaj tiv thaiv corrosion, kub tsis kam, siab tawv hardness thiab siab elasticity thiab toughness.
(2) Daim ntawv thov: ABS feem ntau yog siv rau hauv daim ntawv thov uas yuav tsum tau muaj zog thiab toughness, xws li nws pib qhov chaw, hluav taws xob enclosures, thiab lwm yam. Nyob rau hauv cov nqe lus ntawm lub hwj chim qaum, ABS feem ntau yog siv los tsim insulators thiab vaj tse.
Hauv cov ntsiab lus, PE, PP thiab ABS muaj lawv tus kheej zoo thiab daim ntawv thov scenarios nyob rau hauv cov hlau ntsaws cov ntaub ntawv ntawm lub hwj chim cables. PE yog dav siv nyob rau hauv hlau thiab cable rwb thaiv tsev rau nws zoo heev hluav taws xob rwb thaiv tsev zog thiab tsis kub tsis kam. PP yog haum rau ntau yam hlau thiab cable vim nws softness thiab zoo xim ceev ceev; ABS, nrog nws lub zog siab thiab tawv, yog siv los thaiv cov khoom siv hluav taws xob thiab cov kab hluav taws xob uas xav tau cov yam ntxwv no.
Yuav ua li cas xaiv cov khoom siv PE, PP thiab ABS zoo tshaj plaws raws li daim ntawv thov ntawm cov hlua hluav taws xob?
Thaum xaiv cov khoom siv PE, PP thiab ABS zoo tshaj plaws, nws yog qhov yuav tsum tau ua tib zoo xav txog cov ntawv thov ntawm cov hlua hluav taws xob.
1. ABS khoom:
(1) Cov khoom siv kho tshuab: ABS cov khoom muaj lub zog siab thiab tawv, thiab tuaj yeem tiv taus cov khoom siv loj.
(2) Nto gloss thiab kev ua tau zoo: ABS cov khoom muaj qhov zoo ntawm gloss thiab kev ua haujlwm zoo, uas yog tsim rau kev tsim hluav taws xob kab vaj tse lossis ntsaws qhov chaw nrog cov kev xav tau zoo thiab kev ua haujlwm zoo.
2. Cov khoom siv PP:
(1) Thaum tshav kub kub tsis kam, tshuaj stability thiab kev tiv thaiv ib puag ncig: PP cov ntaub ntawv paub txog nws cov cua sov zoo, tshuaj stability thiab kev tiv thaiv ib puag ncig.
(2) Hluav taws xob rwb thaiv tsev: PP muaj qhov zoo tshaj plaws hluav taws xob rwb thaiv tsev, tuaj yeem siv tsis tu ncua ntawm 110 ℃ - 120 ℃, haum rau txheej rwb thaiv tsev sab hauv ntawm cov kab hluav taws xob lossis ua cov ntaub qhwv rau cov hlau.
(3) Daim ntawv thov teb: PP yog siv dav hauv cov khoom siv hauv tsev, cov khoom ntim khoom, rooj tog zaum, cov khoom siv ua liaj ua teb, cov khoom siv hauv tsev thiab lwm yam kev lag luam, qhia tias nws muaj ntau yam kev siv thiab kev ntseeg tau.
3, PE khoom:
(1) Corrosion kuj: PE daim ntawv muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem nyob ruaj khov hauv cov tshuaj lom neeg xws li kua qaub thiab alkali.
(2) Rwb thaiv tsev thiab nqus dej tsawg: PE daim ntawv muaj cov rwb thaiv tsev zoo thiab nqus dej tsawg, ua rau PE daim ntawv muaj kev siv ntau hauv cov khoom siv hluav taws xob thiab hluav taws xob.
(3) Flexibility thiab cuam tshuam tsis kam: PE daim ntawv kuj muaj qhov ua tau zoo thiab kev cuam tshuam, haum rau kev tiv thaiv sab nraud ntawm cov kab hluav taws xob lossis ua cov ntaub qhwv rau cov hlau los txhim kho nws cov kav ntev thiab kev nyab xeeb.
Yog tias cov kab hluav taws xob xav tau lub zog siab thiab qhov zoo ntawm lub ntsej muag, cov khoom siv ABS yuav yog qhov kev xaiv zoo tshaj plaws;
Yog tias cov kab hluav taws xob xav tau kev kub ntxhov, tshuaj lom neeg kev ruaj ntseg thiab kev tiv thaiv ib puag ncig, PP cov khoom tsim nyog dua;
Yog tias cov kab hluav taws xob xav tau kev tiv thaiv corrosion, rwb thaiv tsev thiab kev nqus dej tsawg, PE khoom yog qhov kev xaiv zoo tshaj plaws.
