Pwm, tsw ntxhiab, txo qhov viscosity, delamination ... Raws li cov teeb meem xim feem ntau, lawv tshwm sim tshwj xeeb tshaj yog thaum lub caij ntuj sov kub, uas yog mob taub hau! Ntawm lawv,cellulose thickener, ib lub kaw lus ua kom tuab uas lwj tau, seb nws puas tuaj yeem tswj tau qhov ruaj khov ntawm lub cev tau dhau los ua qhov tseem ceeb rau kev zam cov teeb meem txheej, thiab nws kuj yog qhov qhia tseem ceeb los ntsuas qhov zoo thiab qhov tsis zoo.
Qhov Txawv: "Mould" thiab "Enzyme"
1. "Pwm" Cov yam ntxwv pom tseeb thiab pom tau rau lub qhov muag liab qab, thiab muaj ntau yam kev sib cuag hauv lub neej txhua hnub. Hauv cov xim, nws yog qhia tias: qhov chaw pwm, tsw ntxhiab tsw phem, tus nqi pH qis dua, kev tso dej thiab kev faib ua pawg, thiab viscosity qis dua. Txoj kev tiv thaiv pwm: fungicide.
2. "Enzyme" Tshwj xeeb yog hais txog cellulase, uas tsis pom tab sis muaj tseeb thiab muaj feem cuam tshuam loj rau cov txheej txheej. Qhov kev ua tau zoo yog: tsis muaj pwm thiab tsis muaj ntxhiab, sedimentation thiab stratification, viscosity txo. Cov txheej txheem tiv thaiv enzyme: kub siab (> 100 ° C) lossis ultraviolet hluav taws xob, kev ruaj khov ntawm cov cellulose thickener.
3. Yog tias qhov txo qis viscosity yog los ntawm cov xim pwm thiab tsw ntxhiab, nws yog qhov tsim nyog los paub meej tias cov tshuaj tua kab mob puas tsis raug vim qhov kub siab; yog tias cov xim tsis pwm lossis tsw ntxhiab, thiab qhov viscosity tsuas yog txo qis, nws yog qhov tsim nyog yuav tsum tau them sai sai rau qhov ruaj khov ntawm cov cellulose nws tus kheej.
Kev Tshuaj Xyuas: Ua rau kom cov viscosity ntawm cov txheej txo qis
1. Cov kab mob raug coj los thaum lub sijhawm tsim xim. Vim tias cov kab mob xav tau lub zog los tsim dua, thiab cellulose yog tsim los ntawm glucose, nws yuav raug kaw ua zaub mov tam sim ntawd. Thaum qhov hnyav molecular ntawm cellulose loj dhau, cov kab mob siv cellulase los hydrolyze qhov saw cellulose, thiab hydrolyze nws mus rau hauv cov chav me me molecular glucose, thiab tom qab ntawd nqus, tsim dua, thiab ua kom cov ntshav ncig sai dua.
2. Cov chaw tsim xim yuav siv cov tshuaj tua kab mob los tua cov kab mob thiab cuam tshuam qhov kev voj voog no. Txawm li cas los xij, cov dej hauv xwm tseem yuav coj cellulase los, thiab cellulase kuj tseem hydrolyzing cov cellulose ntu tas li, tab sis nws tshwm sim qeeb qeeb yam tsis ua kom lub voj voog sai dua.
3. Anti-enzyme cellulose tsis yog "mildew" tab sis "enzyme": hauv lub txheej txheej uas tsis muaj qhov kub thiab txias siab thiab ultraviolet radiation, anti-enzyme tsuas yog tuaj yeem vam khom kev ruaj khov ntawm cellulose nws tus kheej.
Cov khoom ua kom tuab ntawm celluloseTam sim no yog hom thickener tseem ceeb tshaj plaws hauv cov xim pleev xim. Nws qhov kev ruaj khov yuav cuam tshuam ncaj qha rau lub xeev hauv-can thiab kev ua haujlwm ntawm tag nrho cov txheej. Ntawm lawv, qhov kev ruaj khov ntawm cov cellulose thickener yuav tsum yog qhov tseem ceeb tshaj plaws thaum cov neeg siv khoom xaiv cov khoom cellulose. Anxin Chemistry muab ntau yam kev daws teeb meem rau cov txheej, thiab yuav txuas ntxiv coj ntau cov lus qhia hauv kev ua haujlwm ntawm cov txheej. Kev xaiv ntse rheological classic, ua tus thawj coj ntawm cov dej-raws li sib.
