Ib yam khoom uas tau txais kev saib xyuas ntau hauv cov tshuaj thiab kev lag luam hauv ntiaj teb yog stearic acid hmoov.
Stearic acid hmoov yog cov hmoov dawb crystalline uas tsis muaj ntxhiab thiab tsis qab. Chemically, nws muaj kev ruaj ntseg zoo thiab thermal stability thiab tsis cuam tshuam rau cov tshuaj tiv thaiv, uas tso cai rau nws tswj nws cov khoom nyob rau hauv ntau qhov chaw. Tsis tas li ntawd, stearic acid hmoov muaj qee yam lubricating thiab hydrophobic zog, thiab cov khoom no nteg lub hauv paus rau nws daim ntawv thov nyob rau hauv txawv teb.
Stearic acid hmoov los ntawm ntau qhov chaw. Nws yog tsuas yog muab los ntawm tej yam ntuj tso tsiaj thiab zaub roj thiab roj, xws li xibtes roj thiab siab. Los ntawm cov txheej txheem ntawm kev ua tshuaj lom neeg thiab kev ua kom zoo dua qub, cov roj fatty acids hauv cov roj thiab cov rog no tau muab cais tawm thiab ua kom huv si kom tau txais cov hmoov stearic acid. Txoj kev ntawm cov khoom siv no ua kom muaj kev ruaj ntseg ntawm nws cov khoom siv thiab txo nws cov kev cuam tshuam ib puag ncig rau qee qhov.
Stearic acid hmoov zoo heev thaum nws los txog rau kev ua tau zoo. Ua ntej, nws yog cov roj nplua nyeem zoo heev uas tuaj yeem txo kev sib txhuam thiab hnav, thiab txhim kho kev ua haujlwm thiab kev pabcuam lub neej ntawm cov tshuab thiab khoom siv. Hauv kev lag luam plastics, qhov sib ntxiv ntawm Stearic acid hmoov tuaj yeem txhim kho kev ua haujlwm ntawm cov yas, ua kom yooj yim rau pwm, thiab ua kom cov khoom tiav thiab ua kom yooj yim ntawm cov khoom yas. Secondly, stearic acid hmoov kuj muaj emulsifying thiab dispersing teebmeem, thiab yog dav siv nyob rau hauv tshuaj pleev ib ce thiab tshuaj. Nws tuaj yeem pab ntau yam khoom xyaw sib tov sib xyaw thiab txhim kho cov khoom zoo thiab ruaj khov. Tsis tas li ntawd, nws tseem ua lub luag haujlwm tseem ceeb hauv kev lag luam roj hmab, uas tuaj yeem txhim kho lub zog thiab kev puas tsuaj ntawm cov roj hmab.
Stearic acid hmoov yog siv rau ntau yam kev siv.
Nyob rau hauv kev lag luam plastics, nws yog ib qho tseem ceeb additive. Piv txwv li, nyob rau hauv zus tau tej cov polyethylene (PE) thiab polypropylene (PP), stearic acid hmoov txhim kho cov ndlwg thiab tso tawm cov khoom ntawm cov yas, uas ua rau kom muaj zog thiab cov khoom zoo. Hauv kev ua cov polystyrene (PS) thiab polyvinyl chloride (PVC), nws ua rau kom cov tawv tawv thiab kub tsis kam ntawm cov yas, nthuav lawv cov kev siv ntau yam.
Stearic acid hmoov kuj tseem yog qhov tseem ceeb hauv cov tshuaj pleev ib ce, qhov uas nws feem ntau yog siv los ua emulsifier thiab kev tswj xyuas qhov sib xws hauv cov khoom tu tawv nqaij xws li cream, lotions thiab lipsticks, ua kom cov khoom zoo nkauj zoo nkauj thiab ruaj khov. Nyob rau hauv cov xim pleev xim, xws li qhov muag ntxoov ntxoo thiab cov hauv paus, nws yuav pab txhim kho cov adhesion thiab lub neej ntev ntawm cov khoom, ua rau nws zoo nkauj dua.
Kev lag luam kws tshuaj kuj siv tag nrho cov txiaj ntsig ntawm cov khoom ntawm stearic acid hmoov. Nyob rau hauv cov tshuaj formulations, nws yuav siv tau raws li ib tug excipient thiab lubricant los pab cov tshuaj kom zoo zoo li tus thiab tso tawm, thiab los txhim kho lub bioavailability ntawm cov tshuaj. Lub caij no, hauv qee cov tshuaj ntsiav tshuaj, stearic acid hmoov kuj tuaj yeem ua lub luag haujlwm hauv kev cais thiab tiv thaiv cov tshuaj.
Hauv kev lag luam roj hmab, stearic acid hmoov tuaj yeem txhawb cov txheej txheem vulcanisation ntawm cov roj hmab thiab txhim kho kev sib txuas ntawm cov roj hmab, yog li txhim kho cov khoom siv dag zog thiab kev laus ntawm cov khoom siv roj hmab. Txawm hais tias nws yog cov log tsheb, roj hmab ntsaws ruaj ruaj lossis roj hmab conveyor siv, stearic acid hmoov ua rau muaj txiaj ntsig zoo rau kev txhim kho lawv qhov zoo thiab kev ua haujlwm.
Tsis tas li ntawd, stearic acid hmoov muaj cov ntawv thov tseem ceeb hauv textile, txheej thiab number case industries. Hauv kev lag luam textile, nws tuaj yeem siv los ua softener thiab dej repellent los txhim kho kev xav thiab kev ua haujlwm ntawm textiles. Nyob rau hauv coatings thiab inks, nws txhim kho cov dispersion thiab stability ntawm pigments thiab txhim khu lub gloss thiab adhesion ntawm coatings.
Hauv kev xaus, stearic acid hmoov plays lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub thiab lub neej nrog nws cov khoom tshwj xeeb, ntau qhov chaw, kev ua tau zoo thiab kev siv ntau yam.
