Low Lint Wipes: Qhov tseem ceeb rau Electronics Manufacturing

Txoj Kev Phem Phem Hauv Koj Lub Rooj Tswjhwm Saib Xyuas Circuit Court: Vim li cas Lint Lit So Tseem Tseem Ceeb Tshaj Li Koj Xav

Txhua yam khoom siv hluav taws xob uas koj tuav tau dim ntawm kev sib ntaus sib tua tsis pom -ib qho tawm tsam tsis ua haujlwm tsis zoo, tab sis tiv thaiv kev sib kis me me uas koj tsis tuaj yeem pom. Qhov kev sib ntaus sib tua no tshwm sim thaum lub sijhawm tsim khoom, qhov twg ib leeg tsis muaj fiber ntau tuaj yeem ua rau lub rooj tsav xwm hluav taws xob muaj kev ntseeg siab. Qhov no yog qhov uas tsis tshua muaj lint so ua tsis yog khoom kim heev, tab sis yog qhov tsim nyog.

Thaum koj solder Cheebtsam rau ntawm lub rooj tsavxwm luam tawm, koj tsis yog txuas cov xov hlau thiab chips xwb. Koj tab tom tsim ib lub kaw lus uas cov teeb liab hluav taws xob taug kev los ntawm txoj hauv kev microscopic, qhov twg cov pob qij txha yuav tsum muaj kev sib cuag zoo tag nrho, thiab qhov twg microscopic noo noo tuaj yeem ua rau xeb uas kis tau zoo li cov tshuaj lom qeeb. Ib qho particle uas tshuav tom qab dhau los ua qhov ua tsis tiav.

Lub Silent Saboteur: Vim Li Cas Lint Destroys Electronics

Flux residue clings rau Circuit Court boards tom qab soldering - nplaum, acidic, thiab tshaib plab rau ya raws. Sab laug tsis huv, nws nyiam cov plua plav thiab ua cov khoom siv hluav taws xob, tsim txoj hauv kev uas hluav taws xob yuav tsum tsis txhob ntws. Plua plav nyob rau ntawm cov kab hluav taws xob raug ua zoo li lub tshuab hluav taws xob, ua rau cua sov thiab nqus pa tawm uas cov khoom xav tau. Tab sis ntawm no yog qhov feem ntau cov tuam txhab tsis nco: cov cuab yeej ntxuav nws tus kheej tuaj yeem qhia txog kev sib kis. Cov ntaub so ntswg thiab cov ntaub ntawv zoo tib yam tso cov fibers tas li. Thaum tus kws tshaj lij so PCB nrog ib daim ntaub sib xws, cov xoob fibers embed lawv tus kheej mus rau hauv cov khoom seem, nyob rau hauv cov khoom siv lead ua, lossis hauv cov kab hluav taws xob.

Qhov tshwm sim tsis yog ib txwm tam sim ntawd. Ntau qhov kev ua tsis tiav tshwm sim hauv thaj chaw, lub hlis lossis xyoo tom qab kev tsim khoom. Ib tus neeg siv khoom siv tam sim ntawd ua tsis tiav vim tias cov fiber ntau uas tau tso tseg thaum kawg ua rau hluav taws xob tiv tauj hauv thermal stress. Qhov no yog vim li cas kev tswj cov kab mob lint tsis tuaj yeem xaiv tau - nws yog qhov muaj txiaj ntsig rau cov khoom lag luam ntseeg tau.

Nkag siab txog Physics ntawm Lint: Vim li cas Fiber Size Matters

Tsis yog tag nrho "lint" yog tsim sib npaug. Tib neeg cov plaub hau ntsuas kwv yees li 70 micrometers inch. Cov plua plav feem ntau yog 5 txog 50 micrometers. Cov txheej txheem hluavtaws fibers hauv cov ntaub so zoo tib yam li ntawm 10 mus rau 30 micrometers -loj txaus los nyob hauv qab cov khoom siv, cuab hauv qab cov ntaub qhwv, thiab sib sau ua ke hauv cov khoom sib txuas.

Cov ntaub ntawv microfiber hloov qhov sib npaug no. Qhov tseeb microfiber muaj txoj kab uas hla ntawm 0.1 mus rau 1 micrometer-100 npaug zoo dua li cov qauv fibers. Qhov kev nplua zoo no ua haujlwm rau ob lub hom phiaj: nws txo qis qhov yuav tshwm sim ntawm cov fiber ntau dhau los ua qhov pom kev sib kis, thiab nws tso cai rau cov khoom siv los ua haujlwm nrog cov qauv nruj dua uas tsis yooj yim los ua.

Chemistry kuj tseem ceeb. Polyester fibers yog inherently hydrophobic-lawv tiv cov dej noo- uas tuaj yeem ua rau lawv txav mus los ntawm cov roj los yog ntub dej thaum ntxuav. Blended fabrics uas ua ke polyester nrog cellulose los yog nylon tsim cov ntaub ntawv nrog zoo wetting zog, txhais tau tias cov fibers nyob twj ywm thiab tsis txhob wandering.

Dej dav hlau kiv puag ncig: Yuav ua li cas niaj hnub Nonwoven Fabrics yog tsim

Qhov no yog qhov uas cov txheej txheem tsim khoom nws tus kheej dhau los ua qhov tseem ceeb. Cov tsoos woven los yog knitted fabrics nyob ntawm txhua yam loops thiab tangles los tuav fibers ua ke. Cov loops no yooj yim heev: lawv tuaj yeem ntes ntawm cov khoom ntse, fray hauv qab abrasion, thiab tso cov fibers thaum muaj kev ntxhov siab.

Cov txheej txheem spunlace-tseem hu ua hydroentanglement- siv qee yam sib txawv: siab- cov dav hlau dej siab. Fibers tau teem rau hauv lub vev xaib xoob, tom qab ntawd raug cov dav hlau ntawm cov dej txav ntawm ntau txhiab phaus ib square inch. Cov dej tsis khi cov fibers chemical; es tsis txhob, nws lub cev entangles lawv, weaving lawv mus rau hauv peb lub matrix -dimensional. Txoj kev no ua rau cov ntaub uas tsis muaj tshuaj binders, tsis muaj cua sov- ntxias distortion, thiab tsis muaj xoob loops tos los. Cov npoo kaw, feem ntau tsim thaum lub sijhawm tsim khoom los tiv thaiv kev tsis sib haum xeeb, txuas ntxiv kaw cov qauv fiber ntau.

Cov khoom zoo li covIndustrial Combi Rollua piv txwv txoj hauv kev no-spunlace nonwoven fabric engineered tshwj xeeb rau cov kev xav tau nruj ntawm kev tsim khoom siv hluav taws xob, muab cov kev ua haujlwm qis qis dua -lint kev ua tau zoo thoob plaws - nplai ntau lawm.
