Dab tsi yog yam uas cuam tshuam rau kev sau cov dej haus aerated filling kab

Feem ntau, qhov tseem ceeb cuam tshuam rau kev txhaws yog lub viscosity ntawm cov kua, ua raws li seb puas muaj gases, khoom hais, thiab lwm yam. dissolves nyob rau hauv cov kua. Feem ntau, cov kua tuaj yeem muab faib ua hom hauv qab no raws li viscosity:
1. Cov kua dej: feem ntau yog hais txog cov kua uas tuaj yeem ntws los ntawm lub voj voog ntawm ib qho kev ceev raws li qhov kev txiav txim ntawm nws tus kheej lub ntiajteb txawj nqus. Tus nqi ntws yog feem ntau cuam tshuam los ntawm cov kua dej viscosity thiab siab, thiab cov khoom ua kua nyias nyias nrog cov dej ntws zoo, xws li cawv, kua txiv hmab txiv ntoo, mis nyuj, thiab lwm yam. Cov ntaub ntawv no muaj cov viscosity tsawg, zoo fluidity, tsis tshua muaj dej tsis kam hauv cov raj xa dej, thiab cov kev xav tau tsawg. rau cov khoom siv dej haus.

2. Semifluid: yog hais txog cov kua uas tuaj yeem ntws hauv lub voj voog hauv qab lub siab ntau dua li nws lub ntiajteb txawj nqus. Nws yog cov khoom siv kua nplaum uas tsis muaj fluidity. Yog tias cov ntaub ntawv xws li kua ntses, roj, thiab lwm yam muaj kev tiv thaiv loj heev thaum ntws hauv cov thawv thiab cov kav dej, lawv feem ntau xav tau qee qhov siab kom tau raws li qhov yuav tsum tau ua.
3. Cov kua dej viscous: Nws feem ntau yog hais txog cov kua nplaum uas muaj cov khoom viscosity tshaj 10000 centipoises thiab cov dej tsis zoo, uas yuav tsum muaj lub zog loj sab nraud kom nws ntws. Xws li: jam, tshuaj txhuam hniav, muab tshuaj txhuam, roj viscosity siab thiab lwm yam ntaub ntawv. Cov ntaub ntawv no feem ntau nyuaj rau ntws hauv cov kav dej me me, thiab cov quab yuam sab nraud yuav tsum tau siv los txhawb lawv cov dej ntws. Yog li, cov ntaub ntawv zoo li no muaj kev xav tau siab rau cov khoom siv dej haus hauv kev ntim khoom.
Rau cov ntaub ntawv ua kua viscosity tsawg, raws li seb cov kua muaj cov pa roj carbon dioxide, nws tuaj yeem muab faib ua ob pawg: tsis muaj roj thiab muaj roj; Nws kuj tseem tuaj yeem muab faib ua cov dej qab zib thiab cov dej haus nyuaj seb lawv puas muaj cawv.
Tau kawg, cov yam ntxwv ntawm cov kua dej kuj tseem cuam tshuam los ntawm cov yam ntxwv xws li kub, viscosity, cov ntsiab lus ntawm cov khoom siv, decomposability, nto nro, lossis cov yam ntxwv ua npuas. Yog li ntawd, cov xwm txheej no yuav tsum tau txiav txim siab thiab tswj xyuas thaum lub sijhawm sau cov dej haus aerated.
