Lub tshuab tov khoom yog cov cuab yeej siv tshuab uas siv cov cuab yeej siv zog thiab lub ntiajteb txawj nqus kom sib tov ob lossis ntau cov ntaub ntawv sib npaug. Thaum lub sij hawm sib tov, qhov chaw sib cuag ntawm cov khoom siv kuj tuaj yeem nce ntxiv los txhawb cov tshuaj tiv thaiv; Nws tseem tuaj yeem ua kom lub cev hloov pauv sai.
Cov khoom siv feem ntau tau muab faib ua plaub pawg: roj thiab cov kua viscosity qis, nruab nrab mus rau siab viscosity kua thiab muab tshuaj txhuam, thiab cov hmoov thiab cov khoom siv sib xyaw ua ke.
Cov khoom siv uas nquag siv tau muab faib ua plaub pawg: roj thiab cov kua viscosity tsawg, nruab nrab mus rau siab viscosity kua thiab muab tshuaj txhuam tshuab, cov khoom siv thermoplastic mixers, thiab hmoov thiab cov khoom siv sib xyaw ua ke.
Cov yam ntxwv ntawm cov pa roj thiab cov kua viscosity tsawg yog cov qauv yooj yim, tsis muaj qhov sib hloov, tsis tshua muaj kev tu thiab kho, thiab kev siv hluav taws xob tsawg. Hom kev sib xyaw tshuab no tau muab faib ua plaub yam ntxiv: kev sib xyaw ua ke ntawm kev sib xyaw ua ke, cov raj xa dej sib xyaw, kev sib xyaw dav hlau, thiab kev sib xyaw ua ke.
Cov khoom siv sib xyaw ua ke feem ntau suav nrog kev hnav-tiv taus alloy khoom tsim, suav nrog kev kub ceev sib xyaw scraper, sib xyaw tis, hnav-tiv taus hauv ob sab phlu, sib xyaw caj npab, sib tov duav, planetary duav, sib tov plows, sib tov pas nrig, sib tov rake, thiab lwm yam.
Kev sib xyaw tshuab ntawm nruab nrab thiab siab viscosity kua thiab pastes feem ntau muaj zog shear cuam tshuam.
Cov khoom siv thermoplastic sib xyaw tshuab yog tsuas yog siv rau kev sib xyaw cov ntaub ntawv thermoplastic (xws li roj hmab thiab yas) nrog cov khoom siv ntxiv; Powdered thiab granular khoom sib xyaw tshuab feem ntau ua haujlwm tsis tu ncua, suav nrog cov tshuab uas sib xyaw ua ke thiab sib tsoo ua haujlwm, xws li lub log rolling tshuab.
Cov khoom txav ntawm lub tshuab agitator kuj tsim cov teebmeem ntawm cov kua thaum sib hloov. Thaum cov kua ntws los ntawm phab ntsa ntawm cov agitator thiab ntau yam khoom ruaj khov ntsia tau rau hauv lub thawv, nws kuj muaj kev cuam tshuam shear, uas tuaj yeem ua rau ntau lub zos eddy tam sim no diffuse.
Rau cov kua uas sib txawv, muaj pes tsawg leeg, thiab immiscibility, cov nyhuv shear thiab muaj zog turbulence generated los ntawm stirring tsim kua muag high-density kua rau hauv me me droplets thiab sib npaug disperse lawv mus rau hauv lub ntsiab kua.
Cov khoom sib xyaw ua ke muaj xws li: plough tov khoom, muab kauv siv tov khoom, lub ntiajteb txawj nqus tsis pub tov khoom, V-zoo li tus tov khoom, muab ob npaug rau kauv cone tov khoom, siab thiab qis ceev kua tov khoom, planetary fais fab tov khoom, thiab lwm yam
