Cov khoom tseem ceeb ntawm cov tsiaj gelatin yog gelatin peptide protein. Ib qho ntawm nws qhov tsis huv hu ua pob txha nplaum. Pob txha nplaum yog lub cev brittle, tawv, thiab khov. Collagen yog ib qho protein uas tsis yaj hauv dej. Tom qab cua sov thiab lwm yam kev kho mob, nws yuav dhau los ua lwm hom protein hu ua colloid, uas tuaj yeem yaj hauv dej kub thiab muaj cov khoom sib txuas. Cov zaj duab xis ntawm pob txha nplaum yog khov kho thiab ywj pheej tom qab tsim.

Cov hlaws kua nplaum pob txha feem ntau yog siv los ua cov nplaum, cov khoom siv electroplating, cov neeg sawv cev sizing, coagulant AIDS.

Thaum siv cov kua nplaum pob txha, ua ntej siv tib lub ntim lossis ntau dua me ntsis dej (qhov zoo dua yog siv dej kub) los ntub cov kua nplaum pob txha li 10 teev, kom cov kua nplaum mos, thiab tom qab ntawd cua sov txog li 75 ℃, kom nws siv tau ua kua nplaum. Qhov sib piv ntawm cov kua nplaum rau dej yuav tsum txiav txim siab raws li qhov viscosity xav tau. Qhov kub ntawm cov kua nplaum kub yuav tsum tsis txhob siab dhau, qhov kub ntau dua 100 ℃ yuav txo qhov viscosity vim yog kev puas tsuaj ntawm cov molecular, cov kua nplaum laus metamorphism. Cov kua nplaum pob txha muaj cov nag me me hauv kev siv, yog li nws yuav tsum siv thaum ntxiv dej kom zoo rau kev sib tov tsim nyog, txhawm rau kho qhov viscosity thiab fluidity.
