Kev taw qhia luv luvntawm Melt-npau taws Mua mob

Lub polymer yaj extruded los ntawm cov ntsia hlau extruder yog sprayed nrog high-ceev thiab high-temperature cua kom lub yaj kwj yog tsis tshua muaj stretched rau tsim ultra-fine fibers.Cov fibers ultra-nplua no yog condensed rau ntawm cov menyuam los ua cov ntaub lim tsis-woven.

Cov txheej txheem ntws: polymer hmoov pub → yaj extrusion → fiber ntau tsim → fiber ntau txias → nplaum ntxiv → trimmed winding → non-woven filter fabric.

Cov kauj ruam ntawm Melt-npau tawsMua mobCkev tso tseg

1. Teem rau ntawm qhov kub thiab cua siab kom ua rau lub tshuab yaj-tshuab txau cov ntaub softer.

Exception tuav

1. Yog tias cov ntaub yaj-tshuab tseem tsis muag hauv qhov kub thiab txias, cov teeb meem yuav muaj xws li: a.kub sensor teeb meem;b.kub tswj teeb meem.Yog tias ob qho teeb meem no raug tshem tawm, koj tuaj yeem nce qhov kub kom txog thaum cov ntaub mos yaj tuaj tawm.Nco ntsoov tias kub dhau heev yuav ua rau crystallization tshwm sim.

2. Cov khoom siv yaj-tshuab loj siv cov khoom siv yaj-tshuab nrog cov yaj ntawm li 1500, thiab cov khoom siv me me tuaj yeem siv cov khoom yaj-tshuab nyob ib ncig ntawm 1300.

3. Yog tias qhov kub ntawm qhov tuag tau teem rau ntawm 210-230 ℃, thiab cua siab qis dua 0.2Mpa, lub tshuab yuav muaj qhov tshwm sim ntawm cov khoom ya, uas tej zaum yuav txawv txav ntawm cov hauv qab no: a.kub sensor teeb meem;b.cua siab teeb meem;c.qhov loj thiab lub kaum sab xis ntawm lub qhov hluav taws xob yog qhov txawv txav.

4. Yog tias cov ntaub nplaum yaj tseem tsis muag los yog pib nkig thaum nws ntxiv rau qhov kub siab heev, cov ntaub yuav pib muag tom qab ntxiv qhov kub thiab txias.Feem ntau ntawm cov laj thawj yog cov teeb meem ntawm lub tshuab yaj.Nws raug nquahu kom hu rau cov chaw tsim khoom siv.Tau kawg, nws tseem yuav tsum txiav txim siab seb puas muaj teeb meem loj nrog cov ntaub ntawv.

5. Qhov sib ntxiv ntawm electret master batch nyob rau hauv ntau lawm feem ntau xav tau cov txheej txheem parameter kom haum rau nws.Siv cov khoom siv hluav taws xob sib txawv, cov txheej txheem kev teeb tsa ntawm tib lub tshuab yaj-tshuab sib txawv.Koj tuaj yeem xa mus rau cov txheej txheem kev hloov kho saum toj no los kho cov ntaub yaj-tshuab mus rau lub xeev zoo tshaj plaws, thiab tom qab ntawd sib piv thiab ntsuas qhov ua tau zoo.

6. Qhov ntau dua ntawm electret master batch, qhov zoo dua cov nyhuv electrostatic.Tab sis tom qab ncav cuag 6%, cov nyhuv peaked.Qhov siab dua qhov sib ntxiv, qhov ntau dua qhov cuam tshuam ntawm cov khoom tiav melt-blown non-woven fabric.

Nqe lus ntawmctrostatic attenuation

1. Tom qab cov ntaub nplaum yaj tau kho nrog electret, ob qho tib si electret master batch thiab PP khoom tuaj yeem raug them nrog hluav taws xob zoo li qub.Cov hluav taws xob zoo li qub ntawm electret master batch nrog ib qho me me ntxiv tuaj yeem ua rau kom ruaj khov pom tus nqi li ntawm 10-20%, qhov kev lwj qeeb qeeb heev hauv ntim thiab khaws cia.

2. Qhov txo qis hauv kev pom feem ntau yog vim qhov me me ntawm electret attenuation ntawm cov hluav taws xob zoo li qub thiab ntau cov yaj ntawm cov cua tshuab pp.

3. Qee cov ntaub uas yaj-tshuab yog mos tab sis lawv cov tawv tawv tsis txaus.Thaum lub sij hawm cia nce, cov ntaub yuav nkig.Thiab nws yog ib qho yooj yim los ua kom txo qhov pom tus nqi.Cov ntaub yaj no feem ntau yog tsim nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias kub.

4. Qhov ntsuas tsis ruaj khov tuaj yeem hloov pauv tau los ntawm kev ua raws li cov txheej txheem no.Ua ntej ntawm tag nrho cov, tsis ntxiv electret master batch thiab electret kev kho mob, ua ib daim ntaub yaj-blown nrog ntau dua qhov yooj yim lub cev pom efficiency.Raws li qhov no, tsis muaj kev kho hluav taws xob tuaj yeem ntxiv, tsuas yog ntxiv electret master batch los ntsuas qhov sib txawv ntawm qhov pom tus nqi.Vim hais tias ib tug zoo electret master batch tuaj yeem tsim hluav taws xob zoo li qub thaum lub caij winding yam tsis muaj kev kho hluav taws xob, uas tuaj yeem txhim kho qhov pom tus nqi ntawm cov ntaub yaj.

5. Lub cev pom tus nqi ntawm cov ntaub yaj-tshuab yog lub hauv paus, thiab cov electret master batch yog tus yuam sij kom ua tiav qhov kev pom kev ruaj khov.

6. Cov tshuab yaj-tshuab sib txawv tuaj yeem ua rau cov ntaub nplaum sib txawv, tshwj xeeb tshaj yog qhov zoo ntawm cov tuag.Qee lub tshuab yaj-blown tsuas tuaj yeem ua tiav 85% pom tus nqi.Yog tias koj xav kom ncav cuag 90% lossis siab dua, koj xav tau cov ntaub ntawv PP zoo dua.

Kho txoj kev ntawm melt-blownntaubua nkig thiab tawv

1. Los ntawm lub tshuab yaj-blown, nws feem ntau tshwm sim los ntawm cov laj thawj hauv qab no: a.kev tsis sib haum xeeb, b.Tsis sib xws thaum tshav kub dissipation tshwm sim los ntawm tsis txaus huab cua tsis zoo rov qab huab cua ntim, thiab kev ntxhov siab sab hauv ua rau brittleness.Ua kom cov huab cua ntim ntawm cov kiv cua txias, kho qhov ntim ntim ntawm extruder, thiab kho qhov kub ntawm cov cua kub tuaj yeem txhim kho qhov teeb meem no.

2. Los ntawm kev xaav ntawm cov ntaub ntawv PP, siv cov khoom siv roj tsawg PP tuaj yeem ua rau cov spinner tuab.Tom qab txias thiab crystallization tag, nws yuav ua rau cov ntaub yaj-tshuab nkig thiab tawv.Kev nyiam yog muab rau cov ntaub ntawv yaj-tshuab nrog lub melting Performance index ntawm ib ncig ntawm 1500. Cov filaments yog nyias, mos thiab tusyees faib, thiab lub resulting melt-blown ntaub yog mos.

3. Yog tias tus thawj coj ntawm cov txheej txheem peroxide nyob rau hauv cov txheej txheem ntawm cov khoom yaj-tshuab yog tsis tswj kom zoo, cov ntaub yog nkig thiab nyuaj.Yog tias cov khoom siv PP thiab kev ua haujlwm kub siab dhau lawm, nws yuav dhau mus rau hauv cov ntsia hlau thiab thermally degraded.Nyob rau hauv cov txheej txheem tsim khoom, cov txheej txheem peroxide yuav tsum ua kom tiav cov saw hlau molecular tawg ua ntej cov ntsia hlau extruded, tiv thaiv cov seem seem los ntawm kev nkag mus rau cov ntaub qhwv tsis-woven kom txuas ntxiv cov tshuaj tiv thaiv.Qhov no yuav tsum muaj kev sib xyaw ua ke zoo ntawm daim ntawv qhia tswj thiab cov khoom siv ntsia hlau.

4. Tsis muaj cov kiv cua rov qab rau kev sau nrog cov menyuam.Tom qab winding, qhov kub ntawm cov ntaub yaj-tshuab yog siab thiab cua sov tsis tuaj yeem sai sai dissipated.Tom qab txias, nws yuav nkig.

5. Rau cov tshuab me me yaj, qhov teeb meem ntawm brittleness thiab tawv tawv tuaj yeem daws tau los ntawm kev xaiv cov khoom siv mis PP raw khoom.

Yuav ua li cas txhim kho lub toughness ntawmyaj-dhau ntaub

1. Txo cov ntaub yaj yaj uas tau txais kev ncua deb thiab kho kom zoo ntawm cov cua kub ntws los yog qhov kub thiab txias kom tsim nyog.Yog hais tias qhov kub thiab txias ambient siab dhau lawm, koj tuaj yeem nce qhov nqus dej hauv qab.

2. Txo qhov extrusion ceev thiab txo cov zis.

3. Ua kom cov fiber ntau fineness thiab txo qhov spinning ambient kub.

4. Txais PP cov ntaub ntawv ntawm compound formula.

Cov saum toj no yog cov ntsiab lus ntawm peb cov neeg ua haujlwm cov kev paub dhau los.Tau kawg, cov teeb meem thiab cov txheej txheem ntawm kev kho lub tshuab yaj-tshuab yog ntau dua li cov saum toj no.Yog tias koj muaj lus nug txog lub tshuab thiab cov ntaub ntawv, koj tuaj yeem tiv tauj peb [email tiv thaiv]
