Lub tshuab ua haujlwm ntawm microwave muaj xws li thermal thiab tsis thermal teebmeem. Kab lus no qhia txog kev siv microwave hauv textile pretreatment, dyeing, printing, thiab xov
Tom qab ntawd, nws tau taw qhia txog kev siv tshuab microwave hauv lwm qhov chaw thiab kev cia siab rau nws txoj kev loj hlob.
Microwaves yog electromagnetic nthwv dej nrog luv luv wavelengths, feem ntau muab faib ua microwave bands xws li 0.1mm mus rau 1m. Nws zaus yog 300 ~ 300000MHz. Feem ntau siv nyob rau hauv kev sib txuas lus, radar navigation, tshaj tawm thiab TV, lub peev xwm electromagnetic nws muaj yog hu ua microwave zog. Tam sim no, tsuas yog 915MHz thiab 2450MHz tau siv dav hauv kev tsim khoom. Microwave hluav taws xob ua ntawm ntau yam ntaub ntawv textile tau txais kev pom zoo los ntawm tib neeg. Tshwj xeeb tshaj yog nyob rau hauv textile pre-kho, dyeing, luam ntawv, thiab tiav cov txheej txheem, nws qhia tau hais tias zoo superiority.
Kev siv cov tshuab microwave hauv textile pretreatment
1.1 Degumming ntawm hemp fibers
Siv microwave irradiation los ua kom sov cov fibers lawv tus kheej tuaj yeem ua kom cov pos hniav puas sai thiab txhim kho cov nyhuv delamination. Hemp fibers xws li hemp fibers
Cov cuab yeej siv tshuab, enzymatic, thiab tshuaj degumming feem ntau yog siv, thiab cov txiaj ntsig ntawm kev siv tshuab microwave kho kom degumm tsis kho hemp nyob rau hauv alkaline tej yam kev mob qhia tau hais tias microwave kev kho mob muaj feem xyuam rau fiber ntau fineness thiab brightness. Ua kom lub sij hawm ua microwave yuav ua rau cov fiber ntau fineness thiab brightness.
1.2 Kev kho kom zoo ntawm cov khoom siv silk
Yuav kom tswj tau qhov tshwj xeeb style thiab zoo nkauj luster ntawm cov khoom siv lo lo ntxhuav, nws yog feem ntau yuav tsum tau ua kom zoo li qub thiab delamination. Rau cov ntaub qhwv muaj zog twisted, lawv cov xov paj twisted muaj zog yog qhov nyuaj rau kev kho kom zoo. Feem ntau, nws yog ib qho tsim nyog yuav tsum tau nce tus neeg sawv cev refining thiab ua lub sij hawm ntev refining ntawm qhov kub thiab txias. Txawm li cas los xij, qhov no tuaj yeem yooj yim ua rau cov untwisted warp threads dhau los ua kom tsis zoo, ua rau muaj qhov tsis xws luag, thiab yuav tsum tau ua haujlwm kub nrog kev ua haujlwm tsis zoo. Yog tias nws raug kev kho mob microwave thaum lub sij hawm ua kom zoo, nws tsuas yog yuav tsum tau kho rau lub sijhawm luv luv los tsim kom muaj cua sov hauv cov ntaub lo lo ntxhuav thiab txhawb cov ntaub delamination. Tom qab ntxuav nrog dej kub, lub hom phiaj ntawm kev ua kom zoo tuaj yeem ua tiav.
Kev siv Microwave Technology hauv Textile Dyeing
Microwave dyeing tuaj yeem siv tau los ntawm kev siv cov ntaub los yog cov txheej txheem cab, uas tuaj yeem tsis tsuas yog siv rau dyeing hydrophilic fibers, tab sis kuj rau dyeing hydrophobic fibers nrog rau kev ntxiv cov additives tsim nyog. Cov dyes tuaj yeem ua rau cov dyes dispersed, reactive dyes, direct dyes, cationic dyes, thiab lwm yam. Thaum dyeing, cov ntaub yog immersed nyob rau hauv ib tug pa dyeing tov thiab ces nkag mus rau hauv ib tug kaw microwave cua sov chamber (team thawv). Nyob rau hauv qhov kev txiav txim ntawm microwaves, cov ntaub sai sai heats li, uas yuav ua rau kom lub diffusion los yog fixation cov tshuaj tiv thaiv ntawm cov xim nyob rau hauv lub fiber. Kev kho mob tom qab staining yog tib yam li cov txheej txheem.
