Lim xovxwm ib txwm muaj xws li 4 hom, polyester (tsiaj) polypropylene (pplropylene (pinlon (polyamide / nylon) thiab vinylon. Tshwj xeeb yog tus tsiaj thiab pp cov ntaub ntawv yog cov khoom siv nrov heev. Phaj thav ncej Lim xovxwm lim ntaub yog siv rau cov khoom siv ua kua tawm, yog li nws yuav tsum muaj cov kua qaub thiab alkali, thiab qee lub sijhawm yuav nyob rau hauv qhov kub thiab txias thiab lwm yam.
Polyester lim ntaub yuav tuaj yeem faib ua tsiaj staple cov, tsiaj ntev xov ntaub thiab tsiaj monofilament. Cov khoom lag luam no muaj cov khoom ntawm cov acid- tsis kam, ncaj ncees alkali-resistance thiab kev ua haujlwm kub yog 130 cenigrade degrees. Lawv tuaj yeem sau tau dav hauv cov tshuaj, tsis muaj ferry melting, centrifught lim, centrifught lim, cov lim dej thiab cov taub lim muaj peev xwm ncav cuag tsawg dua 5microns.
Polypropylene lim ntaub muaj ntaub ntawm cov kua qaub-actance, me me lub ntiajteb txawj nqus, thiab kev khiav hauj lwm kub tshaj plaws ntawm 90 centigrade degree. Lawv feem ntau yog siv nyob rau hauv precision tshuaj, qab zib, kev lag luam cov roj siv, siv cov ntxaij lim dej, cov ntxaij lim dej, nruas lim dej ect. Lub lim precision tuaj yeem ncav cuag tsawg dua 1 micron.
Cov khoom siv zoo
Acid thiab alkali tsis kam, tsis yooj yim rau corrode, kub tsis kam, tsawg kub tsis kam, lim dej zoo.
Cov hnav zoo esistance
Ua tib zoo xaiv cov khoom siv, ua tib zoo ua cov khoom, tsis yooj yim rau kev puas tsuaj thiab muaj lub neej ntev kev pabcuam.
Ntau hom kev siv
Nws yog dav siv hauv tshuaj lom neeg, pharma-nautical, metallurgy, dyestuff, zaub mov brewing, ceramics thiab kev tiv thaiv kev lag luam.
