Dab tsi yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm cov khoom coated?
Txheej txheej yog txheej txheem dav, thiab cov ntsiab lus tseem ceeb cuam tshuam rau qhov zoo ntawm cov khoom coated yog txheej tus neeg sawv cev, hauv paus ntaub thiab kev siv tshuab.
Txheej tus neeg sawv cev yog tus yuam sij rau kev cuam tshuam cov khoom zoo ntawm txheej txheej. Cov txheej txheem kev ntsuas ntawm tus neeg saib xyuas txheej, ntxiv rau qhov loj me me, viscosity, pH tus nqi, hom ionic, thiab cov ntsiab lus ntawm cov khoom, rau cov txheej txheem siv rau cov khaub ncaws fabrics, zaj duab xis yuav tsum yog mos tab sis tsis nplaum. Yog hais tias cov ntsiab lus ntawm methyl methacrylate los yog methyl acrylate siab, txhais tes xav tias yuav nyuaj, thiab cov ntsiab lus me me, uas yuav cuam tshuam rau lub zog ntawm cov yeeb yaj kiab. Qhov kev faib ua feem ntawm butyl acrylate yog ntau dhau, thiab txhais tes zoo li mos, tab sis nws yuav nplaum. Yog li ntawd, tus neeg sawv cev txheej yuav tsum muaj viscosity haum rau kev ua, thiab cov viscosity tuaj yeem hloov kho los ntawm kev ntxiv cov thickener, tab sis nws yuav tsum muaj rheology zoo los pab txhawb kev ua haujlwm. Lwm qhov piv txwv yog tias cov khoom siv dej tsis zoo yuav tsum muaj cov txheej txheem ua kom tau raws li cov dej siab tsis kam ntawm cov khoom tsis zoo, yog li cov ntsiab lus yuav tsum siab. Cov ntsiab lus ntawm cov txheej txheem txawv teb chaws tuaj yeem ncav cuag 60 feem pua, thaum cov ntsiab lus ntawm cov khoom siv hauv tsev tsuas yog 40 feem pua ntawm feem ntau, feem ntau nyob ib ncig ntawm 30 feem pua. Vim yog qhov sib ntxiv ntawm qee yam tshuaj ntxiv rau tus neeg saib xyuas txheej, npuas feem ntau tsim thaum lub sijhawm ua haujlwm, uas yuav cuam tshuam rau cov dej siab ua haujlwm. Tus neeg sawv cev txheej kuj xav tau kev sib raug zoo nrog lwm cov khoom siv tshuaj, txwv tsis pub nws yuav yooj yim ua thinner lossis thicker, uas yuav cuam tshuam rau txheej txheej txheej.
Lub hauv paus ntaub siv rau txheej yuav tsum tau kho ua ntej, thiab cov ntaub yuav tsum tsis txhob nqa surfactants xws li acid, alkali thiab lwm yam detergents. Tsis xws luag xws li luag xim, riam hlau thiab lwm yam. Qhov saum npoo ntawm cov ntaub kuj yuav tsum tau ua kom du thiab du, cov xov paj tau teeb tsa kom zoo, thiab yuav tsum tsis muaj "txoj kev tsis sib xws", "nruj khawm" thiab lwm yam tshwm sim, kom cov scraper tuaj yeem sib npaug thiab tsis yooj yim nkag mus. mus rau sab nraub qaum ntawm cov ntaub, yog li txhim kho qhov kev xav ntawm tes.
Qhov zoo ntawm cov ntaub ntawv tsis muaj dej tsis zoo yog nyob ntawm qhov warp thiab weft ntom ntawm cov ntaub. Lub nruj yog siab thiab waterproofness yog zoo; Txwv tsis pub, cov dej tsis zoo. Thaum siv tib txheej txheej txheej txheej, cov dej tsis zoo yog 47.24 pieces / cm × 27.56 pieces / cm (120 pieces / nti × 70 pieces / inch) ntau dua 39.37 pieces / cm × 20.87 pieces / cm (100 / nti × 53 / nti) ntau dua 16.93 / cm × 24.8 / cm (43 / inch × 63 / nti). Cov txheej txheem txheej txheej yog nyob ntawm kev siv cov khoom kawg thiab lub hauv paus ntaub. Piv txwv li, ntshiab paj rwb canvas hluav taws tua khaub ncaws yuav tsum muaj kev ua haujlwm tsis zoo ntawm kev ntxhua khaub ncaws thiab dej tiv thaiv. Vim yog qhov tsis tshua muaj warp thiab weft ceev ntawm lub hauv paus ntaub thiab qhov tsis sib xws ntawm cov ntaub, nws yog qhov nyuaj rau ua tau raws li qhov yuav tsum tau ua. Vim li no, nws yog ib qho tsim nyog los ua kom cov txheej txheem ntau ntxiv thiab ntxiv cov khoom siv ntxiv hauv cov txheej txheem txheej txheem.
