Lub hauv paus ntsiab lus degreasing ntawm textile degreasing agents: Degreasing agents, tseem hu ua roj removers los yog roj removers, yog siv nyob rau hauv ntau industries, nrog rau cov hlau tu. Txawm li cas los xij, cov tshuaj degreasing no txawv kiag li ntawm cov siv hauv kev lag luam textile. Cov qub tshem tawm cov roj stains thiab roj los ntawm cov hlau ua tiav thaum lub sijhawm tsim khoom, tab sis cov roj stains tsuas yog ua raws li cov hlau nto. Nyob rau hauv sib piv, textile degreasing agents feem ntau yog siv los tshem tawm cov roj stains sab laug los ntawm spinning thiab weaving txheej txheem ntawm hluavtaws fibers, uas twb tau woven rau hauv fabrics. Yog li ntawd, lawv yuav tsum muaj kev nkag mus zoo thiab tsis ua rau cov ntaub. Kev lag luam sib txawv muaj cov ntawv thov sib txawv thiab cov kev xav tau rau cov neeg ua haujlwm degreasing, uas ua rau muaj kev sib txawv kiag li.
Lub hauv paus ntsiab lus ntawm degreasing cov neeg ua haujlwm yog kev sib xyaw ua ke ntawm surfactants thiab detergent builders, xws li ntub dej, nkag mus, emulsification, dispersion, thiab ntxuav. Cov tshuaj degreasing siv cov additive thiab synergistic los ntawm hydrophilic thiab lipophilic pawg nyob rau hauv ntau yam surfactants kom tau ib tug haum HLB tus nqi (Hydrophile-Lipophilic Balance tooj). Thaum cov degreaser adsorbs ntawm qhov sib cuam tshuam ntawm cov tshuaj thiab cov roj stain, cov pawg hydrophilic ntawm cov degreaser taw tes rau cov tshuaj, thaum cov pab pawg lipophilic taw tes rau cov roj stain (ntawm cov ntaub), ua raws li cov kev taw qhia tshwj xeeb. Qhov no txo qis qhov nro ntawm cov roj -kua interface. Nrog kev pab ntawm lub tshuab agitation, cov roj stain seem ntawm cov ntaub loosens thiab disperses mus rau hauv me me roj droplets, detaching los ntawm cov ntaub nto. Cov surfactant thiab detergent ces ntxiv dag zog rau cov nyhuv los ntawm emulsification thiab dispersion, tiv thaiv cov roj tee los ntawm merging los yog re-adhering rau cov ntaub nto, yog li ua tiav lub hom phiaj ntawm tshem cov roj stain.
