Span 80, tshuaj hu ua sorbitan monoleate, yog ib qho nonionic surfactant thiab yog siv dav hauv teb xws li zaub mov, tshuaj, tshuaj pleev ib ce thiab kev lag luam.
Kev lag luam khoom noj khoom haus: Span 80 muaj cov khoom zoo heev emulsifying, uas tuaj yeem sib xyaw cov roj thiab dej, tiv thaiv kev sib cais ntawm cov roj thiab dej hauv cov zaub mov, thiab txhim kho kev ruaj ntseg thiab saj ntawm cov zaub mov. Yog li ntawd, nws yog dav siv los ua emulsifier. Nws tuaj yeem siv rau hauv kev tsim cov khoom noj xws li margarine, khoom noj siv mis, chocolate thiab dej haus.
Kev lag luam tshuaj pleev ib ce: Span 80 muaj emulsifying zoo heev, dispersing thiab solubilizing zog. Hauv cov tshuaj pleev ib ce, nws feem ntau yog siv los ua emulsifier hauv kev tsim cov tshuaj pleev, tshuaj pleev thiab lwm yam khoom. Nws muaj peev xwm sib tov cov roj theem thiab dej theem kom tsim tau ib qho kev ruaj khov emulsion system. Nyob rau tib lub sijhawm, nws kuj muaj qee yam moisturizing nyhuv, uas pab tswj cov dej noo ntawm daim tawv nqaij thiab ua rau cov tawv nqaij mos thiab du.
Hauv kev lag luam kws tshuaj, Span 80 feem ntau yog siv los ua emulsifier, solubilizer thiab dispersant. Nws tuaj yeem siv los npaj cov ntawv siv tshuaj xws li emulsions thiab liposomes, txhim kho kev ruaj ntseg thiab bioavailability ntawm cov tshuaj.
Kev lag luam textile: Span 80 tuaj yeem siv los ua textile additive thiab muaj zog xws li softening, smoothing thiab anti-static. Nws tuaj yeem txo qhov kev sib txhuam coefficient ntawm fibers, muab textiles ib tug mos tes xav thiab zoo luster. Nyob rau tib lub sijhawm, nws tuaj yeem txo qhov tsim hluav taws xob zoo li qub, txhim kho qhov zoo thiab ua haujlwm ntawm textiles.
Coatings thiab inks kev lag luam: Span 80 tuaj yeem siv los ua cov khoom tawg thiab emulsifier. Nyob rau hauv cov txheej txheem, nws muaj peev xwm sib npaug disperse pigments nyob rau hauv cov xim puag, tiv thaiv pigment sedimentation thiab caking, thiab txhim khu lub npog lub hwj chim thiab stability ntawm txheej. Nyob rau hauv tus number case, Span 80 pab emulsify thiab disperse tus number case, ua kom nws zoo dua pauv thiab ua raws li cov ntaub ntawv luam tawm thaum lub sij hawm luam ntawv, yog li txhim kho cov luam ntawv zoo.
Kev lag luam yas: Span 80 tuaj yeem siv los ua tus neeg sawv cev antistatic thiab lubricant rau cov yas. Nws tuaj yeem tsim cov zaj duab xis conductive rau ntawm cov yas, tso tawm hluav taws xob zoo li qub, tiv thaiv cov yas saum npoo los ntawm adsorbing plua plav thiab impurities vim qhov sib txuam ntawm cov hluav taws xob zoo li qub, thiab tib lub sijhawm txhim kho kev ua haujlwm ntawm cov yas, txo cov kev sib txhuam thaum lub sij hawm ua, thiab ua kom cov khoom zoo thiab cov khoom zoo.
Hauv kev ua liaj ua teb, Sipan 80 tuaj yeem siv los ua ib qho ntxiv rau cov tshuaj tua kab emulsifiers thiab cog kev loj hlob regulators. Raws li emulsifier rau cov tshuaj tua kab, nws tuaj yeem sib cais cov khoom xyaw nquag hauv cov tshuaj tua kab hauv dej, tsim cov emulsion ruaj khov, yog li txhim kho daim ntawv thov thiab kev nyab xeeb ntawm cov tshuaj tua kab. Raws li ib qho ntxiv rau cov tswj kev loj hlob, Span 80 tuaj yeem pab cov nroj tsuag kev loj hlob regulators zoo dua nkag mus rau hauv cov nroj tsuag lub cev thiab txhim kho lawv cov kev ua tau zoo.
