3. ABS (acrylonitrile-butadiene-styrene copolymer):
(1) Cov yam ntxwv: ABS yog cov khoom siv thermoplastic polymer uas muaj zog heev, tawv zoo thiab ua tau yooj yim. Nws muaj qhov zoo ntawm acrylonitrile, butadiene thiab styrene peb monomers, yog li nws muaj kev tiv thaiv tshuaj lom neeg corrosion, tiv thaiv kub, tawv nto siab thiab elasticity thiab toughness siab.
(2) Daim Ntawv Thov: ABS feem ntau yog siv rau hauv cov ntawv thov uas xav tau lub zog siab thiab kev tawv, xws li cov khoom siv hauv tsheb, cov thawv hluav taws xob, thiab lwm yam. Hais txog cov xov hluav taws xob, ABS feem ntau yog siv los tsim cov insulators thiab cov tsev.
Hauv kev xaus, PE, PP thiab ABS muaj lawv tus kheej qhov zoo thiab cov xwm txheej siv rau hauv cov ntaub ntawv ntsaws hlau ntawm cov xov hluav taws xob. PE siv dav hauv kev rwb thaiv tsev hlau thiab cable rau nws cov khoom rwb thaiv tsev hluav taws xob zoo heev thiab tsis kub. PP yog qhov tsim nyog rau ntau yam hlau thiab cable vim nws qhov mos thiab xim zoo; ABS, nrog nws lub zog siab thiab kev tawv, yog siv los rwb thaiv tsev cov khoom hluav taws xob thiab cov xov hluav taws xob uas xav tau cov yam ntxwv no.
Yuav ua li cas xaiv cov khoom siv PE, PP thiab ABS uas haum tshaj plaws raws li qhov yuav tsum tau ua ntawm txoj hlua fais fab?
Thaum xaiv cov ntaub ntawv PE, PP thiab ABS uas tsim nyog tshaj plaws, nws yog ib qho tsim nyog yuav tsum xav txog qhov yuav tsum tau ua ntawm cov xov hluav taws xob.
1. Khoom siv ABS:
(1) Cov khoom siv kho tshuab: Cov khoom siv ABS muaj lub zog siab thiab qhov nyuaj, thiab tuaj yeem tiv taus cov khoom siv loj.
(2) Qhov ci ntsa iab thiab kev ua haujlwm zoo: Cov khoom siv ABS muaj qhov ci ntsa iab thiab kev ua haujlwm zoo, uas yog qhov tsim nyog rau kev tsim cov tsev fais fab lossis cov khoom ntsaws nrog qhov xav tau siab thiab kev ua haujlwm zoo.
2. Cov khoom siv PP:
(1) Kev tiv taus kub, kev ruaj khov tshuaj lom neeg thiab kev tiv thaiv ib puag ncig: Cov khoom siv PP paub txog nws qhov kev tiv thaiv kub zoo, kev ruaj khov tshuaj lom neeg thiab kev tiv thaiv ib puag ncig.
(2) Kev rwb thaiv hluav taws xob: PP muaj kev rwb thaiv hluav taws xob zoo heev, tuaj yeem siv tas li ntawm 110 ℃ -120 ℃, tsim nyog rau txheej rwb thaiv tsev sab hauv ntawm txoj kab hluav taws xob lossis ua cov ntaub ntawv sheath rau cov hlau.
(3) Cov teb thov: PP siv dav hauv cov khoom siv hauv tsev, cov khoom ntim khoom, rooj tog, cov khoom ua liaj ua teb, cov khoom siv hauv tsev thiab lwm yam teb, qhia tias nws muaj ntau yam kev siv tau thiab kev ntseeg siab.
3, PE khoom:
(1) Kev tiv thaiv corrosion: PE daim ntawv muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem ruaj khov hauv cov tshuaj lom neeg xws li kua qaub thiab alkali.
(2) Kev rwb thaiv tsev thiab kev nqus dej tsawg: PE daim ntawv muaj kev rwb thaiv tsev zoo thiab kev nqus dej tsawg, ua rau PE daim ntawv muaj kev siv dav hauv cov teb hluav taws xob thiab hluav taws xob.
(3) Kev yoog tau thiab kev cuam tshuam tsis kam: PE daim ntawv kuj muaj kev yoog tau zoo thiab kev cuam tshuam tsis kam, tsim nyog rau kev tiv thaiv sab nraud ntawm txoj kab hluav taws xob lossis ua cov ntaub ntawv sheath rau cov hlau kom txhim kho nws cov khoom siv ruaj khov thiab kev nyab xeeb.
Yog tias cov xov hluav taws xob xav tau lub zog siab thiab qhov ci ntsa iab zoo, cov khoom siv ABS yuav yog qhov kev xaiv zoo tshaj plaws;
Yog tias cov xov hluav taws xob xav tau kev tiv thaiv cua sov, kev ruaj khov tshuaj lom neeg thiab kev tiv thaiv ib puag ncig, cov khoom siv PP yog qhov tsim nyog dua;
Yog tias cov xov hluav taws xob xav tau kev tiv thaiv corrosion, rwb thaiv tsev thiab nqus dej tsawg, PE khoom yog qhov kev xaiv zoo tshaj plaws.
