Kev ua tau zoo ntawm cov khoom siv yas

Piv nrog rau lwm cov ntaub ntawv, plastics muaj tsib yam kev ua tau zoo hauv qab no:
Lub teeb yuag: Yas yog cov khoom sib zog nrog cov txheeb ze sib txheeb ntawm 0.90 thiab 2.2.Yog li ntawd, txawm tias cov yas tuaj yeem ntab mus rau hauv dej, tshwj xeeb tshaj yog cov yas foamed, vim tias cov micropores hauv nws, qhov kev ntxhib los mos yog sib dua, thiab qhov sib npaug ntawm qhov sib npaug tsuas yog 0.01.Cov cuab yeej no tso cai rau cov yas siv rau hauv kev tsim cov khoom uas yuav tsum tau txo qhov hnyav.
Kev ruaj ntseg tshuaj zoo heev: Cov yas feem ntau muaj kev tiv thaiv zoo rau cov tshuaj xws li acids thiab alkalis.Tshwj xeeb tshaj yog cov polytetrafluoroethylene (F4) feem ntau hu ua tus huab tais ntawm plastics, nws cov tshuaj stability yog txawm zoo dua li cov kub, thiab nws yuav tsis deteriorate yog hais tias nws yog boiled nyob rau hauv "aqua regia" rau ntau tshaj kaum teev.Vim tias F4 muaj tshuaj lom neeg ruaj khov zoo, nws yog cov khoom siv zoo tshaj plaws corrosion-resistant, xws li F4 tuaj yeem siv los ua cov khoom siv rau kev xa cov corrosive thiab viscous kua pipelines.

Kev ua tau zoo ntawm cov hluav taws xob rwb thaiv tsev: Cov yas zoo tib yam yog cov khoom siv hluav taws xob tsis zoo, thiab lawv qhov kev tiv thaiv saum npoo thiab ntim tsis kam yog qhov loj heev, uas tuaj yeem qhia tau tus lej txog 109-1018 ohms.Lub zog tawg yog loj, thiab tus nqi dielectric poob tangent yog me me.Yog li ntawd, plastics muaj ntau yam kev siv hauv electronics thiab machinery industries.
Cov khoom siv hluav taws xob tsis zoo muaj qhov cuam tshuam ntawm kev txo suab nrov thiab kev poob siab: Feem ntau hais lus, thermal conductivity ntawm cov yas yog qhov tsawg, sib npaug rau 1/75-1/225 ntawm cov hlau., zoo dua suab rwb thaiv tsev thiab poob siab tsis kam.Nyob rau hauv cov nqe lus ntawm thermal rwb thaiv tsev, ib lub iav yas qhov rais yog 40% siab dua ib lub iav txhuas qhov rais, thiab ob chav iav qhov rais yog 50% siab dua.Tom qab lub qhov rais yas ua ke nrog cov iav insulating, nws tuaj yeem siv rau hauv cov tsev nyob, cov tsev ua haujlwm, pawg ntseeg thiab tsev so, txuag cua sov thaum lub caij ntuj no thiab txuag cov nqi cua txias rau lub caij ntuj sov, thiab cov txiaj ntsig tau pom tseeb heev.
Kev faib tawm dav ntawm txhua yam muaj zog thiab muaj zog tshwj xeeb: qee cov yas yog tawv xws li pob zeb thiab hlau, thiab qee qhov yog mos xws li ntawv thiab tawv;los ntawm qhov kev xav ntawm cov khoom siv xws li hardness, tensile lub zog, elongation thiab cuam tshuam lub zog ntawm cov yas, qhov kev faib tawm dav dav, muaj ntau chav rau kev xaiv.Vim yog qhov tshwj xeeb me me thiab lub zog siab ntawm cov yas, nws muaj lub zog tshwj xeeb.Piv nrog rau lwm cov ntaub ntawv, plastics kuj muaj qhov tsis txaus ntseeg, xws li yooj yim rau hlawv, tsis muaj zog ntau li hlau, tsis zoo rau kev laus, thiab tsis kub-resistant.
