Gelatin
Kev piav qhia
Gelatin yog ib yam khoom uas pom tseeb, tsis muaj xim, thiab tsis muaj saj, feem ntau yog los ntawm collagen uas tau los ntawm cov tsiaj txhu lub cev. Nws yog ib yam khoom siv los ua kom cov kua dej khov.
Cov khoom no yog dawb los yog daj daj, pob tshab rau translucent, glossy brittle flakes lossis hmoov av, yuav luag tsis muaj ntxhiab thiab tsis qab.
Cov khoom no yog soluble hauv dej kub, cov organic acids xws li acetic acid, salicylic acid thiab phthalic acid, nrog rau urea, thiourea, thiocyanate, cov concentration siab potassium bromide lossis potassium iodide kua; insoluble hauv dej txias, thiab insoluble hauv cov organic solvents xws li ether, ethanol lossis chloroform.
Cov gelatin muaj nyob rau hauv kev lag luam yog cov hydrophilic colloid nrog lub luag haujlwm ntawm kev tiv thaiv colloid, uas tuaj yeem siv los ua stabilizer thiab emulsifier rau hydrophobic colloids. Nws kuj yog ib qho multifunctional dispersant, binder, thickener, stabilizer thiab emulsifier.
Cov gelatin noj tau tuaj yeem nqus tau 5-10 npaug ntawm nws qhov hnyav hauv dej. Thaum cua sov, nws nkag mus rau hauv lub xeev sol; thaum txias, nws nkag mus rau hauv lub xeev gel. Vim yog qhov tshwj xeeb no, nws feem ntau siv hauv kev lag luam khoom qab zib.
Cov Lus Qhia Tshwj Xeeb
Daim Ntawv Thov
Cov khoom no siv tau dav hauv ntau yam khoom hauv phaj, ntais ntawv, pub tsiaj, ntim khoom, ua ntawv, textile, luam ntawv, ceramic, roj av, tshuaj lom neeg txhua hnub, txheej, metallurgy thiab lwm yam lag luam, feem ntau ua lub luag haujlwm ntawm thickening, stabilizing, coagulating, blending, polishing, sizing, adhesion thiab fixing dej. Cov xwm txheej tseem ceeb ntawm daim ntawv thov yog raws li nram no:
Cov nplaum teb:Nws tuaj yeem siv los tsim cov kua nplaum jelly, gauze, sandpaper, glued wood edition books, thiab kuj siv tau rau cov kab sib dhos khoom plig, cov twj paj nruag high-end thiab kev lag luam rooj tog;
Kev lag luam ntaub:Nws tuaj yeem txhim kho qhov tawv, lub zog, du thiab elasticity ntawm cov fibers, thiab tiv thaiv kev tawg ntawm fiber;
Kev tsim khoom ntawm Paintball:Nws tuaj yeem siv ua cov khoom siv tseem ceeb rau kev ua cov plhaub paintball lossis matrices, kom ntseeg tau tias muaj peev xwm ua tau zoo thiab ua tau zoo ntawm cov paintballs.
Kev Ua Tau Zoo thiab Cov Txiaj Ntsig Tseem Ceeb
1. Kev ua tau zoo heev, uas tuaj yeem paub txog kev khov thiab molding ntawm cov kua kab lis kev cai, nrog rau lub zog gel yooj yim hloov pauv hauv qhov ntau ntawm 30-260bloom;
2. Muaj ntau yam khoom siv xws li kev nplaum, kev tuab, kev ruaj khov, kev sib xyaw thiab kev sib kis, ua tau raws li cov kev xav tau ntawm ntau yam lag luam thiab cov xwm txheej;
3. Hydrophilic colloid nrog kev tiv thaiv colloid, uas tuaj yeem siv ua tus stabilizer thiab emulsifier rau hydrophobic colloids;
4. Kev ua haujlwm ruaj khov viscosity, uas tuaj yeem tswj tau qhov ntsuas viscosity raws li qhov sib txawv ntawm cov concentration thiab kub, hloov kho rau cov txheej txheem ntau lawm sib txawv.
Kev Khaws Cia thiab Ntim Khoom
Kev Khaws Cia：Cov khoom no yuav tsum tau khaws cia rau hauv qhov chaw qhuav, cua nkag thiab huv si.
Cov Lus Qhia Txog Kev Ntim Khoom：Yuav tsum tau kho raws li cov neeg xav tau
