1. Lub teeb yuag
Yas yog cov khoom sib zog nrog qhov sib txheeb ze ntawm 0.90-2.2.Pom tseeb, cov yas puas tuaj yeem ntab saum dej?Tshwj xeeb yog foamed plastics, vim hais tias ntawm cov micropores sab hauv, qhov kev ntxhib los mos yog sib dua, thiab cov txheeb ze ntom ntom tsuas yog 0.01.Cov yam ntxwv no tso cai rau cov yas siv rau hauv kev tsim cov khoom lag luam uas yuav tsum tau lightening ntawm lawv tus kheej qhov hnyav.
2. Zoo heev tshuaj stability
Cov yas feem ntau muaj qhov zoo corrosion kuj rau cov tshuaj xws li acids thiab alkalis.Tshwj xeeb, polytetrafluoroethylene (F4), feem ntau hu ua King of Plastics, muaj tshuaj lom neeg ruaj khov dua li kub, thiab nws yuav tsis ua kom zoo dua txawm tias nws tau rhaub 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.Piv txwv li, F4 tuaj yeem siv los ua cov khoom siv rau kev xa cov kav dej corrosive thiab viscous.
3. Cov khoom siv hluav taws xob zoo heev
Ordinary plastics yog cov khoom siv hluav taws xob tsis zoo, thiab lawv qhov kev tiv thaiv saum npoo thiab ntim tsis kam yog loj heev, uas tuaj yeem ncav cuag 109 txog 1018 ohms hauv cov lej.Lub zog tawg yog loj, thiab tus nqi dielectric poob tangent yog me me.Yog li ntawd, plastics muaj ntau yam kev siv hauv kev lag luam electronics thiab machinery kev lag luam.Xws li yas insulated tswj cables.
4. Cov thermal conductor tsis zoo, nrog kev txo suab nrov thiab kev poob siab absorbing nyhuv
Feem ntau hais lus, cov thermal conductivity ntawm cov yas yog qhov tsawg, sib npaug rau 1/75-1/225 ntawm cov hlau, thiab cov micropores ntawm cov yas ua npuas ncauj.
Nws muaj cov pa roj, uas muaj cov rwb thaiv tsev zoo dua, suab rwb thaiv tsev thiab kev poob siab.Piv txwv li, thermal conductivity ntawm polyvinyl chloride (PVC) tsuas yog 1/357 ntawm cov hlau thiab 1/1250 ntawm txhuas.Nyob rau hauv cov nqe lus ntawm thermal rwb thaiv tsev muaj peev xwm, ib-iav yas qhov rais yog 40% siab dua ib-iav txhuas qhov rais, thiab ob-iav qhov rais yog 50% siab dua.Tom qab lub qhov rais yas ua ke nrog cov iav hollow, 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.
5. Kev faib tawm dav ntawm txhua yam muaj zog thiab muaj zog tshwj xeeb dua
Qee cov yas yog tawv li pob zeb thiab hlau, thiab qee qhov yog mos li ntawv thiab tawv.Los ntawm qhov kev xav ntawm cov khoom siv xws li hardness, tensile zog, elongation, thiab cuam tshuam lub zog ntawm cov yas, lawv muaj ntau yam kev faib tawm thiab muaj ntau txoj kev xaiv rau kev siv.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, cov yas kuj tseem muaj qhov tsis zoo, xws li cov nplaim taws, siab tawv dua li cov hlau, tsis muaj kev laus tsis kam, thiab kub tsis kam.
Yog li ntawd, peb cov khoom siv yas siv cov ntaub ntawv yas raws li qhov xwm txheej ntawm cov khoom
Piv txwv li:diavCov khoom lag luam yog cov zaub mov qib PP thiab qib kho mob PP.
Covkoob txhajyog qib kho mob PP, thiabcevmuaj qib kho mob PP lossis PS.Covtshuaj tsuag lub raj misNws yog ib qho kev sib xyaw ntawm PET thiab PP.
Vimpwmcov ntaub ntawv uas peb siv yog cov pwm zoo heev, xws li 718. Qhov zoo ntawm cov khoom yas ua tau zoo heev.Peb muaj 13 xyoo ntawm kev paub keeb kwm hauv cheeb tsam no, kev tshaj lij heev
