Dec 06, 2017
Thaum nws tawm los tiv thaiv cov yeeb yaj duab, peb tsis paub, vim thaum lub sijhawm thaum peb qhib ib qho khoom tshiab, peb ib txwm pom ib lub yeeb yaj kiab los sis tuab cov yeeb yaj kiab. Los ntawm cov kev ua haujlwm ntawm kev ua haujlwm, qhov tseeb, yog los tiv thaiv cov khoom ntawm lub cev kom ntxiv ib txheej ntawm zaj duab xis.
Yog li ntawd, muaj ntau yam zoo li cov khoom siv pov hwm cov khoom muaj nyob rau hauv kev lag luam, uas tuaj yeem siv rau cov khoom siv hlau, coated hlau khoom qhov chaw, khoom yas, khoom siv hluav taws xob, khoom deg thiab lwm yam khoom nto.
Yog li, cov yeeb yaj kiab tau muaj ntau hom kev siv hauv ntau lub lag luam. Yog li, thaum xaiv, dab tsi yuav tsum yog tus txheej txheem? Ua ntej tshaj plaws, thaum ntim khoom sib txawv, txawv viscosities yuav tsum tau vim yog lawv qhov sib txawv ntawm cov khoom.
Ua lwm yam lus, hauv kev xaiv ntawm cov yeeb yaj kiab, thawj zaug yuav tsum muaj kev tiv thaiv raws li cov yam ntxwv ntawm cov khoom los txiav txim siab txog cov qauv tsim nyog. Lub hauv paus ntsiab lus uas cuam tshuam rau stickiness muaj xws li qe, molecular zog thiab diffusion, thiab nkag mus. Piv txwv, qee qhov yeeb tshuaj tsuas tuaj yeem nyob ze ze nrog lub ntsej muag ntawm qhov khoom yuav tsum adhered tom qab nws tau zoo lawm.
Qhov thib ob, rau cov khoom sib txawv, cov yeeb yaj kiab tiv thaiv txawv ntawm qhov txawv (viscosity) kuj yuav tsum tau txawm tias lawv qhov chaw ze heev. Tsis tas li ntawd, cov txheej txheem ua tom ntej tseem yuav muaj kev sib raug zoo nrog qhov kev pom zoo. Raws li ib txwm muaj, kev rov qab ua haujlwm khiav lag luam xws li khoov, thwj, txiav, drilling thiab thermoforming.
Tsis tas li ntawd, kev xaiv ntawm kev tiv thaiv zaj duab xis, tab sis kuj them mloog mus rau tuab ntawm nws loj, thiab kom paub meej tias lub viscosity thiab match. Tab sis kuj xyuam xim rau cov yeeb yaj kiab uas muaj kev tiv thaiv lub zog thiab kev loj hlob kom paub meej thiab muaj zog los ua kom tau raws li cov cai. Qhov tseeb tiag, qhov zoo tshaj plaws uas yuav ua tau qhov no yog los sim kom zoo kom koj thiaj li tau txais ntau yam tseeb.
