HPMC, tseem hu ua hydroxypropyl methylcellulose, yog ntau yam polymer siv nyob rau hauv ntau yam kev lag luam, suav nrog kev lag luam yas.HPMC yog ib qho cellulose derivative tau los ntawm kev hloov kho tshuaj ntawm ntuj cellulose.HPMC yog siv rau hauv cov yas ua pwm tso tawm tus neeg sawv cev, softener, lubricant, thiab ntau lwm yam kev siv.Kab lus no yuav tham txog ntau yam kev siv HPMC hauv cov yas thiab lawv cov txiaj ntsig thaum zam cov ntsiab lus tsis zoo.
Plastics yog cov khoom siv hluavtaws lossis semi-synthetic uas tau siv dav hauv ntau yam kev siv vim lawv muaj ntau yam, durability thiab nqi-zoo.Txawm li cas los xij, kev ua thiab molding ntawm cov yas yuav tsum tau siv cov additives xws li tso cov neeg ua hauj lwm, softeners thiab lubricants los txhim kho lawv cov khoom thiab yooj yim ntawm kev ua.HPMC yog cov khoom siv ntuj tsim thiab nyab xeeb nrog ntau daim ntawv thov hauv kev lag luam yas.
Ib qho kev siv tseem ceeb ntawm HPMC hauv cov yas yog ua cov pwm tso tawm tus neeg sawv cev.HPMC ua raws li cov yeeb yaj kiab yav dhau los, ua ib qho kev thaiv ntawm cov pwm yas thiab cov khoom yas, tiv thaiv cov yas los ntawm cov pwm.HPMC nyiam dua lwm cov pwm tso tawm cov neeg ua haujlwm xws li silicone, siv quav ciab, thiab cov khoom siv roj vim nws tsis muaj tshuaj lom, tsis muaj xim, thiab tsis cuam tshuam rau qhov zoo li ntawm cov khoom yas.
Lwm qhov tseem ceeb ntawm kev siv HPMC hauv cov yas yog ua cov softener.Cov khoom siv yas tuaj yeem tawv thiab yuav tsis haum rau qee qhov kev siv.HPMC tuaj yeem siv los hloov kho cov tawv tawv ntawm cov yas kom ua rau lawv yooj yim dua thiab mos.HPMC feem ntau yog siv los tsim cov yas mos thiab hloov tau yooj yim, xws li cov khoom kho mob thiab kho hniav, cov khoom ua si thiab cov khoom ntim khoom noj.
HPMC tseem yog cov roj nplua nyeem zoo uas tuaj yeem siv los txhim kho kev ua cov yas.Plastic processing muaj cua sov cov khoom yas thiab txhaj rau hauv pwm thiab extruders.Thaum lub sij hawm tus txheej txheem, cov khoom yas tuaj yeem lo rau cov tshuab, ua rau jams thiab qeeb hauv kev tsim khoom.HPMC yog cov roj nplua nyeem zoo uas tuaj yeem txo qhov kev sib txhuam ntawm cov yas thiab cov tshuab, ua rau kev ua cov khoom yas yooj yim dua.
HPMC muaj ntau qhov zoo dua lwm cov khoom siv ntxiv hauv cov yas.Piv txwv li, HPMC yog biodegradable thiab ib puag ncig tus phooj ywg, ua rau nws tsim nyog siv rau hauv cov khoom lag luam.HPMC kuj tsis muaj tshuaj lom thiab tsis muaj kev phom sij rau cov neeg ua haujlwm lossis cov neeg siv khoom.Tsis tas li ntawd, HPMC tsis muaj xim thiab tsis muaj ntxhiab, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom uas zoo li thiab saj yog qhov tseem ceeb, xws li cov khoom ntim khoom noj.
HPMC yog sib xws nrog lwm cov yas additives thiab tuaj yeem siv ua ke nrog lawv kom tau txais cov khoom xav tau.HPMC tuaj yeem sib xyaw nrog cov yas yas rau kev hloov pauv, cov khoom ntim rau lub zog, thiab cov khoom ruaj khov rau kev ua haujlwm ntev thiab ntev.Qhov ntau yam ntawm HPMC ua rau nws muaj txiaj ntsig zoo ntxiv hauv kev tsim cov yas.
HPMC yog ntau yam thiab muaj txiaj ntsig yas ntxiv.HPMC yog siv rau hauv cov yas ua pwm tso tawm tus neeg sawv cev, softener, lubricant, thiab ntau lwm yam kev siv.HPMC muaj ntau qhov zoo dua lwm cov khoom siv ntxiv hauv cov yas, xws li biodegradable, non-toxic thiab environmentally friendly.HPMC kuj tau sib xws nrog lwm cov yas additives thiab tuaj yeem siv ua ke nrog lawv kom ua tiav cov khoom xav tau.HPMC tau hloov pauv kev lag luam plastics thiab tej zaum yuav ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom lag luam ruaj khov thiab zoo ib puag ncig.
