Polypropylene Spunlace Nonwoven Npuag

I. Cov yam ntxwv tseem ceeb ntawm Polypropylene spunlace Nonwoven Fabric: Cov txiaj ntsig sib txawv ncaj qha hais txog cov teeb meem ntawm cov xwm txheej

Polypropylene spunlace nonwoven fabric, vam khom cov yam ntxwv ntawm cov ntaub ntawv raw thiab spunlace technology, tsim peb lub ntsiab lus tseem ceeb, hais meej txog qhov tsis zoo ntawm cov ntaub ntawv nonwoven ib txwm muaj nyob rau hauv cov xwm txheej tshwj xeeb thiab dhau los ua qhov kev xaiv khoom siv tau yooj yim heev:

1. Tiv taus xeb, tsis muaj dej + tsis nqus dej noo: Qhov kev xaiv "ruaj khov" rau cov xwm txheej ntub thiab xeb

Kev hloov pauv tau ob qho tib si rau ib puag ncig hnyav: Tsis zoo li cov fiber ntuj xws li paj rwb thiab viscose uas yooj yim pwm thiab polyester uas tsis tiv taus kev xeb muaj zog, polypropylene spunlace non-woven fabric muaj zog heev tiv taus cov kua qaub thiab alkalis muaj zog xws li 30% hydrochloric acid thiab 20% sodium hydroxide, nrog rau cov organic solvents xws li ethanol thiab roj av. Tus nqi poob ntawm lub zog tawg tom qab 72 teev ntawm kev immersion yog ≤3%. Ntxiv mus, nws cov dej nqus tus nqi tsuas yog 0.01%, thiab nws tseem qhuav tag nrho yam tsis muaj pwm hauv ib puag ncig noo noo. Nws yog ib qho khoom siv tshwj xeeb rau kev cob qhia tshuaj lom neeg thiab cov xwm txheej sab nraum zoov noo noo.

Qhov kev ua tau zoo tsis raug cuam tshuam: Qhov tsis muaj dej tsis cuam tshuam rau qhov ua pa tau (nrog rau qhov ua pa tau ntawm 1200-1800mL/(m² · s)). Yog tias siv ua daim ntaub ntxuav hauv pem teb hauv chav dej, nws tuaj yeem nqus tau cov dej noo sai sai thiab tiv thaiv nws tus kheej kom tsis txhob pwm, daws qhov teeb meem ntawm cov ntaub ntxuav ib txwm uas "ntub ntau npaum li koj so".

2. Lub teeb yuag, muaj zog thiab ua tau zoo ntawm tus nqi: Ib qho cuab yeej "kev txhim kho tus nqi" rau cov xwm txheej tsim khoom ntau

Kev sib npaug ntawm qhov sib dua thiab lub zog: Qhov ceev ntawm polypropylene fiber tsuas yog 0.91g / cm³, ua rau nws yog qhov sib dua ntawm cov tshuaj fibers feem ntau. Cov khoom ntawm tib thaj chaw yog 15% sib dua li polyester thiab 30% sib dua li paj rwb. Yog tias cov khoom siv no siv rau hauv cov khaub ncaws tiv thaiv pov tseg, qhov hnyav tuaj yeem txo tau 20%, txo qhov hnyav rau tus neeg hnav. Tib lub sijhawm, los ntawm cov txheej txheem hla-spunlace, lub zog tawg ntev yog ≥18N / 5cm, lub zog ntub tsis poob qis, thiab lub zog ruaj khov yog sib piv rau cov ntaub polyester tsis-woven nruab nrab thiab siab.

3. Kev ua haujlwm yooj ywm + kev ua haujlwm zoo: Kev daws teeb meem "teb sai" rau ntau yam kev xav tau

Kev hloov kho kom haum rau kev ua haujlwm tsis muaj kev tsis sib haum Nws tuaj yeem ua ke nrog cov haujlwm xws li tiv thaiv hluav taws xob (qhov tsis kam ntawm qhov chaw 10⁸-10¹¹Ω), hluav taws kub (oxygen index ≥28%), thiab tua kab mob (tus nqi tua kab mob ≥99%) yam tsis muaj cov txheej txheem nyuaj. Ntxiv mus, tom qab ntxuav 20 zaug, tus nqi khaws cia ua haujlwm tuaj yeem ncav cuag ntau dua 85%. Piv txwv li, daim ntaub so tiv thaiv hluav taws xob hauv lub Hoobkas khoom siv hluav taws xob tsis tsuas yog tshem tawm cov plua plav thiab cov roj av xwb tab sis kuj tiv thaiv kev puas tsuaj rau cov khoom. daws cov kev txwv kev hloov pauv ntawm cov ntaub ntawv ua haujlwm ib zaug.

Qhov ua tau zoo ntawm kev ua cov ntaub ntawv zoo dua li cov txheej txheem ib txwm muaj: Lub ntsiab lus yaj ntawm polypropylene fiber yog qis (165-170 ℃), thiab qhov kub teeb tsa tsuas yog 80-100 ℃, uas txuag tau 30% zog piv rau polyester teeb tsa. Ntxiv mus, cov fibers muaj zog zoo. Tsis muaj kev tawg ntawm fiber lossis paj ya thaum lub sijhawm carding thiab spunlacing. Txij li kev hloov kho mus rau kev tsim khoom tiav, nws tsuas yog siv sijhawm 7 hnub (polyester ib txwm siv sijhawm 12 hnub), nrog rau tus nqi khoom tiav ntawm 99.5%. Nws tuaj yeem teb sai rau cov neeg siv khoom cov lus txib ceev thiab cov kev xav tau tus kheej.

II. Cov teb tseem ceeb ntawm cov ntaub polypropylene spunlace non-woven: Cov ntaub ntawv tseem ceeb uas npog ntau qhov xwm txheej

Raws li cov yam ntxwv tseem ceeb saum toj no, polypropylene spunlace non-woven fabric tau siv dav hauv plaub qhov chaw tseem ceeb: kev tsim khoom lag luam, kev saib xyuas kev huv, lub neej hauv tsev, thiab kev tiv thaiv sab nraum zoov, dhau los ua cov khoom siv nyiam hauv ntau qhov xwm txheej.
