HPMC (Hydroxypropyl Methylcellulose) yog siv dav hauv cov tshuaj ntxuav tes. Nws cov kev siv tseem ceeb suav nrog kev ua kom tuab, txhim kho ua npuas ncauj ruaj khov, thiab ua haujlwm raws li tus neeg sawv cev ncua thiab gelling tus neeg sawv cev.
1. Thickener
HPMC yog lub siab molecular hnyav cellulose derivative nrog zoo heev thickening zog. Ntxiv HPMC rau cov tshuaj ntxuav tes tuaj yeem ua kom cov viscosity ntawm cov tshuaj detergents, ua rau cov tshuaj detergents muaj fluidity zoo dua thiab txheej txheej. Qhov no yog qhov tseem ceeb rau ntau hom detergents (xws li kua ntxhua khaub ncaws ntxhua khaub ncaws, xab npum tais, thiab lwm yam) vim tias viscosity tsim nyog tuaj yeem txhim kho qhov kev paub ntawm kev siv cov khoom.
2. Txhim kho ua npuas ncauj stability
Lwm lub luag haujlwm tseem ceeb ntawm HPMC hauv cov tshuaj ntxuav tes yog txhawm rau txhim kho cov npuas dej kom ruaj khov. Ua npuas ncauj yog ib qho tseem ceeb qhia txog kev ntxuav cov tshuaj ntxuav tes. HPMC tuaj yeem tsim ua npuas ncauj ruaj khov thiab ua kom lub zog ntawm cov npuas dej, yog li txhim kho cov nyhuv ntawm cov tshuaj ntxuav tes. Nws cov npuas dej ruaj khov yog qhov tshwj xeeb tshaj yog thaum siv, ua rau cov tshuaj ntxuav tes ua npuas dej ntev dua thaum siv thiab txhim kho cov neeg siv kev paub.
3. Tus neeg saib xyuas ncua
HPMC muaj cov cuab yeej ncua kev kawm zoo thiab tuaj yeem tiv thaiv cov khoom hauv cov tshuaj detergents los ntawm kev daws teeb meem. Nws yog feem ntau yuav tsum tau ntxiv ib co granular cov khoom xyaw rau detergents, xws li detergents los yog detergents. HPMC tuaj yeem pab cov khoom no kom sib npaug hauv cov kua thiab zam kom tsis txhob muaj sedimentation lossis stratification. Qhov no ua kom zoo sib xws thiab ua haujlwm zoo ntawm cov tshuaj ntxuav tes thaum siv.
4. Gelling tus neeg sawv cev
HPMC kuj tseem siv tau los ua tus neeg sawv cev gelling los muab qee yam khoom gelling rau cov tshuaj ntxuav tes. Los ntawm kev kho qhov concentration ntawm HPMC, qhov fluidity thiab sib xws ntawm cov tshuaj ntxuav tes tuaj yeem tswj tau. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov khoom siv xab npum uas xav tau ib qho viscosity. Piv txwv li, qee cov tshuaj ntxuav tes yuav tsum muaj cov khoom zoo li gel kom yooj yim rau kev thov lossis tsom mus rau kev ntxuav qee qhov chaw.
5. Txhim khu kev ruaj ntseg
HPMC muaj cov tshuaj zoo thiab thermal stability thiab tuaj yeem tswj nws lub cev thiab tshuaj lom neeg nyob rau hauv ntau yam pH thiab kub. Qhov no tso cai rau HPMC ua haujlwm ruaj khov nyob rau hauv cov txheej txheem sib txawv thiab kev cia khoom, txhim kho kev ruaj ntseg ntawm cov tshuaj ntxuav tes.
6. Lwm cov haujlwm
Lubricity: HPMC tuaj yeem muab cov tshuaj ntxuav tes rau qee qhov ntawm lubricity, txo qhov hnav ntawm cov ntaub ntawv saum npoo thaum lub sijhawm ntxuav, tshwj xeeb tshaj yog thaum ntxuav cov khoom muag.
Non-toxic thiab biodegradable: Raws li lub ntuj cellulose derivative, HPMC muaj biodegradability zoo thiab tsis muaj tshuaj lom, ua kom muaj kev nyab xeeb ntawm ib puag ncig thiab cov neeg siv.
Daim ntawv thov ntawm HPMC hauv cov tshuaj ntxhua khaub ncaws feem ntau tsom rau kev ua kom tuab, txhim kho ua npuas ncauj ruaj khov, raug tshem tawm, gelling, thiab lwm yam, uas ua rau muaj txiaj ntsig zoo thiab kev siv ntawm cov tshuaj detergents. Nws cov tshuaj lom neeg ruaj khov thiab biodegradability kuj ua rau HPMC yog ib qho khoom siv nrov heev thiab ua lub luag haujlwm tseem ceeb hauv kev lag luam tshuaj ntxuav tes.
