Hauv kev lag luam ntim khoom, muaj cov khoom siv tiv thaiv tshwj xeeb hu ua nto tiv thaiv zaj duab xis, uas tau muab tso rau ntawm qhov chaw ntawm ntau yam hlau phaj, daim hlau yas, iav, thiab lwm yam los tiv thaiv qhov zoo ntawm cov khoom thaum thauj, ua, cia thiab siv, uas yuav tsum tau Pressure-sensitive tiv thaiv nplaum / acrylic nplaum / PU nplaum nrog kev ua tau zoo heev.
Viscosity thiab lwm yam khoom rheological ntawm cov nplaum yog cov khoom tseem ceeb tshaj plaws uas cuam tshuam rau cov txheej txheem txheej txheem ntawm kev tiv thaiv zaj duab xis. Raws li kev vam khom ntawm viscosity nrog shear ceev, cov kua yuav muab faib ua Newtonian kua, expansive lub cev thiab pseudoplastic lub cev. Raws li kev hloov pauv ntawm viscosity shear lub sij hawm, cov kua dej tuaj yeem muab faib ua Newtonian kua, thixotropic lub cev thiab lub cev rheological, Qhov loj dua cov cuab yeej rheological ntawm cov nplaum deviates los ntawm Newtonian kua, qhov ntau nws yog rau ntau yam teeb meem zoo hauv kev ua haujlwm txheej. . Tshwj xeeb tshaj yog thaum cov nplaum nthuav tawm cov cuab yeej ntawm lub cev nthuav dav, nws cov viscosity yuav nce nrawm nrog qhov nce ntawm txheej ceev hauv txheej txheej txheej. Tiv thaiv zaj duab xis chaw tsim tshuaj paus Yichuan zaj duab xis.
Tus yuam sij rau kev tsim cov yeeb yaj kiab tiv thaiv saum npoo yog xaiv cov txheej txheem txheej txheej tsim nyog thiab coater raws li cov txheej txheem ntawm kev tiv thaiv zaj duab xis thiab cov kev cai tshwj xeeb ntawm cov yeeb yaj kiab tiv thaiv, thiab txiav txim siab ntau yam txheej txheem ntawm kev ua haujlwm coater. Lub zog siv tshuab loj yuav tsum tau siv los nthuav cov nplaum. Yog li ntawd, qhov ceev ntawm txheej txheej yog, qhov nyuaj dua nws yog kom tau txais ib txheej txheej. Nws feem ntau muaj zog heev los rub tawm lub substrate thiab tseem ua rau lub scraper puas. Thaum cov nplaum nthuav tawm thixotropic kev ua tau zoo, cov qib ntawm cov nplaum txheej yog qhov tsis zoo thaum lub sij hawm txheej, yog li nws nyuaj kom tau txais cov nplaum nplaum thiab du.
