5 daim ntawv thov kom pom cov txhim kho ntawm cov xov uas tsis siv xov | JINHAOCHENG

China is the world's major consumer of yaj yaj tsis txau cov cov ntaub tsis sib thooj, with the consumption per capita of melt-spraying non-woven fabrics exceeding 1.5kg. Although there is still a gap between China and developed countries such as Europe and the United States, the growth rate is obvious, which also indicates that China's melt-spraying non-woven fabric industry has further space.

Vim tias tus nqi siab ntawm cov cuab yeej siv thiab kev tsim khoom siab thiab kev ua haujlwm siab, tus nqi siab ntawm cov khoom siv tshuaj txau, ua ke nrog kev nkag siab tsis zoo ntawm kev ua haujlwm thiab kev siv, ua kom cov molten tshuaj lag luam tsis tuaj yeem qhib, thiab cov lag luam muaj feem xyuam yog tawm tsam, nyuaj rau kev khiav lag luam.Qhov hauv qab no yog kev txhim kho qauv tsom xam ntawm yaj txau cov tsis-ntaub ntaub kev lag luam.

Melt-sprayed non-woven cloth is the "heart" of surgical masks and N95 masks.The analysis of melt-spraying non-woven fabric industry indicates that the more important melt-spraying non-woven fabric for medical masks has fewer enterprises to provide

China's melting spray nonwoven manufacturing has two types of continuous and intermittent, continuous production line is mainly imported melting spray die head, the other parts of the assembly line by the enterprise itself. With the improvement of China's manufacturing level in recent years, domestic melting spray die head has gradually gained more market share.The development trend of melt-spray nonwoven fabric industry is analyzed from five major applications.

1. Thov hauv huab cua lim teb

Kev tsim kho tshiab ntawm kev sib xyaw melt-tshuaj tsuag tsis-woven npuag kev lag luam, siv rau hauv cov cua ua kom huv, ua lub sub-high efficiency, high efficiency air filter core thiab siv rau kev ntxhib ntxoo thiab nruab nrab kev ua haujlwm ntawm huab cua ntawm qhov loj npaum li cas.

Nws muaj qhov zoo ntawm qis tsis kam, siab zog, zoo tshaj acid thiab alkaline tsis kam, tiv thaiv corrosion, ruaj khov kev ua haujlwm, kev pab lub neej ntev thiab tus nqi qis.Yog tsis muaj luv luv tshwm sim ntawm cov khoom siv lim tawm hauv cov roj lim.

2. Daim ntawv thov hauv thaj chaw kho mob thiab kev noj qab haus huv

Lub qhov ncauj plua plav ua los ntawm cov yaj ua kom yaj thiab cov tshuaj txau muaj qhov tsis ua pa zoo, tsis muaj qhov huab cua tsis zoo, thiab cov plua plav ua haujlwm kom txog li 99%. Nws yog dav siv hauv tsev kho mob, chaw ua zaub mov noj, cov mines thiab lwm qhov chaw ua haujlwm uas xav tau plua plav thiab kab mob-pov thawj.

Cov khoom lag luam yog ua los ntawm cov yeeb yaj kiab tiv thaiv thiab pleev xim tom qab kev kho mob tshwj xeeb, nrog huab cua zoo permeability, tsis muaj tshuaj lom los ntawm sab thiab siv tau yooj yim. SMS khoom ua ke nrog spunbonded daim ntaub yog siv dav hauv kev ua khaub ncaws phais thiab kaus mom thiab lwm yam khoom ntxuav.

3. Cov khoom ua kua pom thiab cov roj teeb ua kom zoo nkauj

Polypropylene melting txau cov tshuaj tsuag yog siv los lim cov kua qaub thiab alkaline kua, roj, roj thiab lwm yam kev ua tau zoo, tau raug suav tias yog cov khoom siv membrane zoo los ntawm kev lag luam roj teeb nyob hauv tsev thiab txawv teb chaws, thiab tau siv dav, tsis tsuas txo tus nqi roj teeb , ua kom yooj yim ntawm cov txheej txheem, thiab zoo heev txo qhov nyhav thiab ntim ntawm lub roj teeb.

4. Roj nqus cov ntaub ntawv thiab cov ntaub so tes

Txhua yam roj-nqus cov ntaub ntawv ua los ntawm polypropylene melting thiab txau daim ntaub tuaj yeem nqus cov roj mus txog 14-15 zaug ntawm nws tus kheej qhov hnyav. Lawv siv dav hauv ib puag ncig tiv thaiv engineering thiab roj-dej sib cais tshuab. Tsis tas li ntawd, lawv tuaj yeem siv cov ntaub ntawv huv si ntawm cov roj thiab hmoov av hauv kev tsim khoom lag luam.Qhov daim ntawv thov muab tag nrho kev ua si rau cov khoom ntawm polypropylene nws tus kheej thiab qhov nqus tau ntawm ultrafine fiber ua los ntawm melting thiab txau.

5. Cov ntaub thaiv hluav taws xob cua sov

Qhov nruab nrab ntawm txoj kab hluav taws xob ntawm cov roj zeb ua cov kab hluav taws xob fiber ntau yog li 0.5 txog 5m, thiab qhov tshwj xeeb cheeb tsam dav yog loj. Cawv cov pores muaj ntau nyob rau hauv daim ntaub, thiab cov porosity yog qhov siab.Qhov qauv no khaws cov huab cua ntau, tuaj yeem tiv thaiv kom tsis txhob muaj cua sov, muaj kev tiv thaiv zoo thaum tshav kub kub, yog dav siv hauv kev tsim cov khaub ncaws thiab ntau yam thermal rwb thaiv tsev cov ntaub ntawv.

Kev txhim kho kev tsom xam ntawm cov yaj-txau tsis-cov ntaub npuag kev lag luam, xws li tawv tsho, tsho da dej, khaub ncaws txias, paj rwb zos daim ntaub, thiab lwm yam, muaj qhov zoo ntawm lub teeb yuag, sov, tsis muaj noo noo, zoo huab cua permeability, tsis muaj ntxau.

Nyob rau hauv kev sib ntaus tawm tsam kev sib kis, yaj txau cov ntaub qhwv tsis-ntaub ua kom pom kev tiv thaiv zoo thiab cais ua haujlwm, tau txais kev lees paub thiab kev nyiam ntawm kev ua lag luam, thiab ua rau muaj kev nthuav dav ntxiv.
