Tsis tas li ntawd, cov hmoov txhuv nplej siab ether kuj tseem tuaj yeem nce cov rheology ntawm cov tsho tiv no, emulsions thiab lwm yam ntaub ntawv, thiab txhim kho lawv cov txheej txheem txheej txheem.
3. Kev ruaj khov thiab kev tawm tsam
Starch ether yuav hloov pauv cov qauv molecular ntawm ib txwm muaj cov hmoov txhuv nplej siab thaum lub sijhawm npaj, ua rau nws ruaj khov. Qhov kev ruaj khov yog qhov tseem ceeb heev hauv cov zaub mov thiab cov tshuaj pleev cov chaw ua haujlwm kom muaj cov khoom lag luam zoo thiab tiv thaiv kev tawm tsam lossis daus. Piv txwv li, hauv kev ua zaub mov noj, hmoov txhuv nplej siab ether tuaj yeem ruaj khov, tiv thaiv dej sib cais, thiab tswj kom muaj kev sib cais thiab cov tsos mob. Hauv cov tshuaj pleev ib ce, nws yog siv los ua cov stabilizer rau emulsions thiab cream los tiv thaiv cov roj-dej sib cais thiab txhim kho cov khoom siv khoom.
4. Emulsification
Raws li surfactant, hmoov txhuv nplej ether muaj qee yam txiaj ntsig emulsification. Nyob rau hauv kev lag luam khoom noj khoom haus, nws tuaj yeem siv los tswj cov roj-dej emulsions thiab tiv thaiv stratification. Tshwj xeeb tshaj yog nyob rau hauv kev tsim cov khoom noj muaj roj tsawg, cov khoom noj khoom haus tshiab tuaj yeem txhim kho cov tshuaj uas muaj txiaj ntsig zoo ntawm cov khoom lag luam no, muab rau lawv saj zoo thiab tsos.
5. Kev khiav dej
Starch ether muaj cov dej nqus dej zoo thiab tuaj yeem tsim cov khoom siv hydrogen nrog cov lwg dej kom nqus thiab khaws dej. Cov cuab yeej no ua lub luag haujlwm tseem ceeb hauv ntau daim ntawv thov. Piv txwv li, hauv kev lag luam artch ete tuaj yeem siv los tswj cov tshuaj tso tawm thiab kev pab kom maj mam tso tawm hauv lub cev, yog li kev txhim kho kev ua tau zoo. Nyob rau tib lub sijhawm, vim nws txoj kev hydration zoo, hmoov txhuv nplej siab ether feem ntau siv rau cov kuab lom txhua hnub kom cov txiaj ntsig zoo ntawm cov khoom lag luam.
6. Khi thiab adhesion cuam tshuam
Cov hmoov txhuv nplej siab tau siv dav hauv kev npaj khoom thiab kev ua zaub mov noj ua lub ntuj. Hauv kev npaj tshuaj, lawv tau siv los ua cov ntsiav tshuaj rau cov ntsiav tshuaj, tsiav tshuaj thiab lwm cov ntaub ntawv ntau npaum li cas kom ntseeg tau tias qhov kev ruaj ntseg ntawm cov tshuaj. Cov nplaum ntawm cov hmoov txhuv nplej siab tuaj yeem txhim kho cov qauv txheej txheem hauv cov khoom noj ua nqaij, lossis cov saj hauv cov khoom qab zib thiab pastries.
7. Cov Ntaub Ntawv Khoom Noj
Cov hmoov txhuv nplej siab tau siv ua cov thickeners, stabilizers, emulsifiers thiab instarders hauv kev lag luam khoom noj. Txij li thaum lawv tau muab tau los ntawm ntuj cov hmoov txhuv nplej siab, lawv feem ntau suav tias yog cov zaub mov kom nyab xeeb. Hauv cov khoom noj muaj roj tsawg lossis cov zaub mov tsis muaj roj, cov hmoov txhuv nplej siab tsis tuaj yeem muab cov khoom zoo xwb, tab sis kuj tseem ua kom txo cov rog rog. Ib qho ntxiv, feem ntau nws siv nyob rau hauv cov khoom xws li kua txiv, jams, kua kua, thiab lwm yam khoom siv ruaj khov thiab muaj txiaj ntsig ntawm cov khoom lag luam no.
8. Tshuaj Siv Tshuaj
Hauv kev lag luam kws tshuaj, cov hmoov txhuv nplej siab feem ntau siv los ua kom muaj tshuaj, tshwj xeeb yog cov ntsiav tshuaj ntau lawm hauv cov ntsiav tshuaj. Lawv tuaj yeem siv los ua cov khoom siv, tua cov khoom siv los ua kom muaj cov tshuaj sib cais thiab tso cov yam ntxwv tso tawm. Los ntawm kev kho cov hom thiab muab cov hmoov txhuv nplej siab ether, cov kev tawm ntawm cov tshuaj yuav ua tiav, yog li kev txhim kho cov kev ua tau zoo thiab txo cov kev mob tshwm sim.
9. Kev thov hauv tshuaj pleev ib ce
Starch Cov neeg txawj ntse tseem muaj dav hauv cov tshuaj pleev ib ce, tshwj xeeb tshaj yog cov khoom lag luam xws li lotions, cream, ntsej muag huv, thiab cov plaub hau tshuaj ntxuav. Hauv cov khoom lag luam no, cov neeg muaj kuab lom zem no tsuas yog siv cov thickeners, stabilizers, thiab moisturizers txhawm rau txhim kho cov khoom siv. Piv txwv li, nws tuaj yeem txhim kho lub qhov siv yuag ntawm cov khoom saib xyuas tawv nqaij, txhim kho cov dej ntawm daim tawv nqaij, thiab tiv thaiv kev sib cais ntawm cov roj thiab dej hauv ntau.
10. Ib puag ncig kev cuam tshuam thiab kev nyab xeeb
Raws li cov neeg ua yeeb yam ntuj, cov hmoov txhuv nplej siab yog ib puag ncig phooj ywg. Piv nrog qee cov tshuaj ntxuav hluavtaws, cov lus muaj kev txawj ntse muaj zoo dua biodegradability thiab yuav tsis ua rau muaj kuab paug rau cov tsiaj txhu. Txawm li cas los xij, thaum siv lawv, saib xyuas yuav tsum tau them nyiaj rau kev siv hluav taws xob hauv lawv cov txheej txheem ntau ntxiv thiab cov kev cuam tshuam ntawm qee cov tshuaj lom neeg saib xyuas ib puag ncig.
Raws li ib qho tseem ceeb muaj cov khoom siv raw, cov hmoov txhuv tau siv dav hauv cov zaub mov, cov tshuaj, tshuaj pleev ib txwm, ua kom zoo nkauj, muaj kev ruaj khov, thiab tsev kho mob. Nrog kev nce qib ntawm thev naus laus zis thiab kev nthuav dav txuas ntxiv, cov hom thiab siv cov hmoov txhuv nplej siab tau dhau los ua kev sib txawv, thiab lawv muaj peev xwm loj hlob rau kev txhim kho yav tom ntej.
