Span 80, tshuaj lom neeg hu ua sorbitan monoleate, yog ib qho nonionic surfactant thiab siv dav hauv cov teb xws li zaub mov, tshuaj, tshuaj pleev ib ce thiab kev lag luam.
Kev lag luam zaub mov: Span 80 muaj cov khoom zoo heev rau emulsifying, uas tuaj yeem sib tov roj thiab dej kom sib npaug, tiv thaiv kev sib cais ntawm roj thiab dej hauv zaub mov, thiab txhim kho kev ruaj khov thiab saj ntawm zaub mov. Yog li ntawd, nws yog siv dav ua emulsifier. Nws tuaj yeem siv rau hauv kev tsim cov zaub mov xws li margarine, cov khoom noj mis nyuj, chocolate thiab dej haus.
Kev lag luam tshuaj pleev ib ce: Span 80 muaj cov khoom zoo heev rau emulsifying, dispersing thiab solubilizing. Hauv kev lag luam tshuaj pleev ib ce, nws feem ntau siv los ua emulsifier hauv kev tsim cov tshuaj pleev ib ce, tshuaj pleev ib ce thiab lwm yam khoom. Nws tuaj yeem sib tov cov roj theem thiab dej theem kom sib npaug los ua ib qho emulsion system ruaj khov. Tib lub sijhawm, nws kuj muaj qee yam moisturizing effect, uas pab tswj cov dej noo ntawm daim tawv nqaij thiab ua rau daim tawv nqaij mos thiab du.
Hauv kev lag luam tshuaj, Span 80 feem ntau yog siv ua emulsifier, solubilizer thiab dispersant. Nws tuaj yeem siv los npaj cov tshuaj xws li emulsions thiab liposomes, txhim kho kev ruaj khov thiab bioavailability ntawm cov tshuaj.
Kev lag luam textile: Span 80 siv tau ua cov khoom siv ntxiv rau textile thiab muaj cov haujlwm xws li ua kom mos, du thiab tiv thaiv hluav taws xob. Nws tuaj yeem txo qhov sib txhuam ntawm cov fibers, muab cov textiles mos mos thiab ci ntsa iab zoo. Tib lub sijhawm, nws kuj tseem tuaj yeem txo qhov tsim hluav taws xob static, txhim kho qhov zoo thiab kev ua haujlwm ntawm cov textiles.
Kev lag luam pleev xim thiab kua mem: Span 80 siv tau ua tus neeg faib thiab emulsifier. Hauv cov txheej pleev xim, nws tuaj yeem faib cov xim sib npaug hauv cov xim pleev, tiv thaiv cov xim tsis sib xyaw thiab ua kom tawv, thiab txhim kho lub zog npog thiab kev ruaj khov ntawm cov txheej pleev xim. Hauv cov kua mem, Span 80 pab emulsify thiab faib cov kua mem, ua rau nws yooj yim hloov thiab lo rau cov ntaub ntawv luam ntawv thaum lub sijhawm luam ntawv, yog li ua kom zoo dua qhov zoo ntawm kev luam ntawv.
Kev lag luam yas: Span 80 siv tau ua tus neeg sawv cev tiv thaiv hluav taws xob thiab roj nplua nyeem rau yas. Nws tuaj yeem tsim ib zaj duab xis conductive rau ntawm qhov chaw ntawm yas, tso tawm hluav taws xob static, tiv thaiv cov yas nto los ntawm kev nqus cov hmoov av thiab cov khoom tsis huv vim muaj hluav taws xob static, thiab tib lub sijhawm txhim kho kev ua haujlwm ntawm cov yas, txo qhov kev sib txhuam thaum lub sijhawm ua, thiab ua kom muaj txiaj ntsig zoo ntawm kev tsim khoom thiab cov khoom zoo.
Hauv kev ua liaj ua teb, Sipan 80 siv tau ua cov tshuaj ntxiv rau cov tshuaj tua kab thiab cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag. Ua cov tshuaj emulsifier rau cov tshuaj tua kab, nws tuaj yeem faib cov khoom xyaw nquag hauv cov tshuaj tua kab hauv dej, tsim cov emulsion ruaj khov, yog li ua kom cov txiaj ntsig ntawm kev siv thiab kev nyab xeeb ntawm cov tshuaj tua kab. Ua cov tshuaj ntxiv rau cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag, Span 80 tuaj yeem pab cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag nkag mus rau hauv lub cev ntawm cov nroj tsuag zoo dua thiab txhim kho lawv cov txiaj ntsig.
