Piv nrog rau cov khoom siv lim dej dav dav, xav tau lim muaj qhov zoo hauv qab no:
1, porosity loj, huab cua zoo permeability, tuaj yeem txhim kho lub peev xwm ntawm cov khoom siv thiab txo qis kev poob siab thiab kev siv zog.Koob-punched lim xav yog ib qho zoo luv fiber ntau lim ntaub nrog staggered kev npaj thiab uniform pore faib.Lub porosity tuaj yeem ncav cuag ntau dua 70%, uas yog ob zaug ntawm cov ntaub lim ntaub.Qhov luaj li cas ntawm lub hnab plua plav collector tuaj yeem txo thiab kev siv hluav taws xob tuaj yeem txo qis los ntawm kev siv rab koob ua lub hnab lim.
2. Kev ua haujlwm siab plua plav thiab tsis tshua muaj roj emission concentration.Cov txiaj ntsig kev sim qhia tau hais tias qhov pom kev ua haujlwm ntawm 325 mesh talc (kwv yees li 7.5μm hauv txoj kab nruab nrab) tuaj yeem ncav cuag 99.9-99.99%, uas yog qhov kev txiav txim siab ntau dua li ntawm flannel.Cov pa roj emission concentration tej zaum yuav muaj ntau hauv qab lub teb chaws tus qauv.
3. Qhov saum npoo yog tiav los ntawm kev sib khi kub thiab kub hnyiab los yog txheej, qhov saum npoo yog du thiab du, tsis yooj yim los thaiv, tsis yooj yim rau deform, yooj yim los ntxuav, kev pab lub neej ntev.Kev pab lub neej ntawm koob xav yog feem ntau 1 ~ 5 npaug ntawm cov ntaub lim ntaub.
4, dav siv, muaj zog tshuaj stability.Nws tuaj yeem lim tsis tsuas yog kub ib txwm lossis kub kub, tab sis kuj corrosive gas uas muaj kua qaub thiab alkali, dej thiab roj pom.Koob lim xav tau dav siv hauv metallurgy, tshuaj lom neeg kev lag luam, cov ntaub ntawv hauv tsev, smelting, lub zog tsim, ceramics, machinery, mining, roj av, tshuaj, dye, zaub mov, grain ua thiab lwm yam lag luam ntawm cov txheej txheem thov, cov ntaub ntawv rov qab, plua plav tswj cov kua. -khoom sib cais thiab lwm yam teb, yog ib qho zoo tagnrho gas purification filtration khoom thiab kua-khoom sib cais nruab nrab.
5, polyester koob xav yog tsuas yog siv rau flue roj kub hauv qab 150 ℃.
Peb lub tuam txhab tuaj yeem muab txhua yam kev xav tau.Hauv qab no yog qhov ua tau zoo ntawm 550 grams
