HydroxyPropyyl Methylcellulose (HPMC) yog dej-soluble polymer compound tau los ntawm kev hloov tshuaj lom neeg ntawm cov cellulose ntuj. Nws yog dav siv nyob rau hauv cov tshuaj pleev ib ce, kws tshuaj, cov ntaub ntawv vaj tsev thiab ntxuav cov khoom lag luam. Hauv cov tshuaj ntxuav, Kimacell® ua si lub luag haujlwm tseem ceeb yog cov tuab dua, stabilizer thiab zaj duab xis-ua tus neeg sawv cev.
1. Cov khoom yooj yim ntawm HPMC
HPMC yog ib qho dawb rau cov hmoov dawb ocorless nrog cov dej zoo solubility thiab biodegradability. Nws cov qauv molecular muaj cov pab pawg hydrophilic xws li methyl (-Och₃) thiab hydroxypropyl (-och₂Tsev noog₃), yog li nws tau muaj zog hydrophilicity thiab zoo solubility. Lub cev hnyav molecular ntawm HPMC, qib kev hloov chaw ntawm hydroxypropyl thiab methyl, thiab lawv cov kev txheeb ze txiav txim siab txiav txim siab ua solubility, thickening muaj peev xwm thiab muaj peev xwm ruaj khov. Yog li ntawd, kev ua haujlwm ntawm HPMC tuaj yeem hloov kho raws li qhov xav tau kom haum rau cov xwm txheej sib txawv.
2. Lub luag haujlwm ntawm HPMC nyob rau hauv detergents
Hauv cov tshuaj ntxuav, HPMC feem ntau yog siv los ua cov tuab thiab muaj stabilizer, thiab feem ntau cuam tshuam rau kev ua haujlwm ntawm cov dument hauv cov hauv qab no:
2.1 Thuab nyhuv
HPMC muaj cov khoom siv thicking muaj zog thiab tuaj yeem nce cov viscosity ntawm cov khoom noj tshuaj ntxuav, muab lawv zoo dua rheological cov khoom ntiag tug. Thickened xabffents tsis tsuas yog pab txo qis dripping, tab sis kuj tseem ua kom muaj kev ruaj khov thiab ua npuas ncauj. Hauv cov tshuaj ntxuav ua kua, HPMC feem ntau siv los kho cov fluidity ntawm cov khoom, ua cov xab npum kom yooj yim dua thiab yooj yim rau kev siv.
2.2 stidilizing ua npuas ncauj
HPMC kuj muaj lub luag haujlwm ntawm stabilizing ua npuas nyob rau hauv detergents. Nws nce viscosity ntawm cov kua thiab txo qhov ceev ntawm ua npuas ncauj tawg, yog li txuas lub durability ntawm npaus. Tsis tas li ntawd, HPMC kuj tseem tuaj yeem txo qhov loj me ntawm npaus, ua npuas ncauj ntau yam thiab muag heev. Cov yam ntxwv no yog qhov tshwj xeeb tshaj yog nyob rau qee cov xab npum uas yuav tsum muaj cov tshuaj zawv plaub hau (xws li zawv plaub hau, da dej gel, thiab lwm yam).
2.3 txhim kho qhov tsis txaus ntseeg ntawm surfactants
Cov qauv molecular ntawm HPMC ua rau nws cuam tshuam nrog surfactant molecules, txhim kho qhov kev tawm tsam thiab solubility ntawm surfactants, tshwj xeeb tshaj yog nyob rau hauv cov dej kub lossis ib puag ncig dej nyuaj. Los ntawm cov nyhuv synergistic nrog surfactants, HPMC tuaj yeem txhim kho kev tu ua kom huv ntawm cov xab npum.
2.4 raws li kev ncua kev ruaj khov
Nyob rau hauv qee cov xab npam uas yuav tsum tau muab ncua tsis muaj cov hmoov av (xws li ntxuav cov khoom siv tsis zoo, yog li txhim kho qhov ua tau zoo thiab siv cov nyhuv ntawm cov khoom lag luam.
3. Cov nyhuv ntawm HPMC ntawm kev ruaj khov ntawm cov xab npum
3.1 nce lub cev ruaj khov ntawm cov mis
HPMC tuaj yeem txhim kho kev ruaj khov ntawm lub cev ntawm cov khoom los ntawm kev kho lub viscosity ntawm cov xab npum. Lub xab npum tuab tuab dua yog cov qauv ntau dua thiab tuaj yeem tiv thaiv qhov tshwm sim ntawm kev sib cais tsis khov xws li theem sib cais, nag lossis daus, nag lossis daus. Hauv cov tshuaj ntxuav ua kua, HPMC ua cov tuab tuab tuaj yeem txo cov theem sib cais ua ke thiab ua kom lub sijhawm ntev ntawm cov khoom lag luam thaum lub sijhawm khaws cia.
3.2 Kev txhim kho pH kev ruaj khov
Tus lej pH cov tshuaj ntxuav tes yog qhov tseem ceeb cuam tshuam rau lawv qhov kev ua tau zoo thiab kev ruaj ntseg. HPMC tuaj yeem hloov kho ph sib txuas lus rau qee yam thiab tiv thaiv kev xab npum los ntawm decomposing lossis detherating nyob rau hauv acidic thiab alkaline ib puag ncig. Los ntawm kev kho cov hom thiab cov kev xav ntawm HPMC, qhov muaj qhov ruaj khov ntawm xab npum nyob rau hauv hom PHQUP sib txawv.
3.3 Txhim kho qhov kub tsis kam
Qee qhov hloov kho cov versions ntawm HPMC muaj cov kub kub ua kom muaj zog thiab tuaj yeem tswj hwm qhov ruaj khov ntawm cov tshuaj ntxuav siab dua. Qhov no ua rau HPMC ntau cov neeg siv dav hauv qhov chaw kub. Piv txwv li, thaum cov tshuaj tua ntxhua khaub ncaws tshuaj ntxuav thiab tshuaj zawv plaub caug yog siv nyob rau hauv qhov kub thiab txias, lawv tseem tuaj yeem tswj lawv lub cev ruaj khov thiab kev cuam tshuam nrog kev cuam tshuam.
3.4 Txhim kho cov dej ua haujlwm nyuaj
Cheebtsam xws li calcium thiab magnesium thiab cov dej khov yuav cuam tshuam qhov ruaj khov ntawm cov tshuaj ntxuav tes, ua rau muaj kev txo qis hauv cov tshuaj ntxuav kom huv. HPMC tuaj yeem txhim kho qhov ruaj khov ntawm cov dej num hauv dej nyuaj rau qee qhov tsis ua haujlwm thiab txo qhov tsis ua haujlwm ntawm kev sib sau nrog eons dej nyuaj.
3.5 Cuam Tshuam Rau Ua Npuas Ncauj
Txawm hais tias HPMC tuaj yeem txhim kho kev ruaj khov ntawm cov tshuaj ntxuav tes, nws cov kev xav tau siab dhau thiab kuj tseem yuav ua rau cov ua npuas dej dhau, yog li cuam tshuam rau kev ntxuav cov nyhuv. Yog li ntawd, nws yog ib qho tseem ceeb kom kho tau cov concentration ntawm HPMC mus rau qhov ruaj khov ntawm foam.
4. Kev ua kom zoo ntawm xab npum tshuaj ntxuav los ntawm HPMC
4.1 Xaiv cov hom uas tsim nyog HPMC
Ntau hom KIMACELL®hpmc (xws li qib sib txawv ntawm kev hloov chaw, hnyav hnyav, thiab lwm yam) muaj cov kev cuam tshuam sib txawv ntawm cov xab npum. Yog li ntawd, thaum tsim cov qauv, nws yog qhov tsim nyog los xaiv HPMC tsim nyog raws li kev siv tshwj xeeb. Piv txwv li, siab molecular hnyav HPMC feem ntau muaj cov nyhuv zoo dua, thaum lub cev qis HPMC tuaj yeem muab cov khoom siv ua npuas dej zoo.
4.2 Kho lub HPMC concentration
Cov concentration ntawm HPMC muaj qhov cuam tshuam tseem ceeb ntawm kev ua yeeb yam ntawm cov xab npum. Tsawg dhau ib qho kev xav tau yuav tsis tau siv nws cov nyhuv txo qis, thaum lub siab dhau los kuj ua rau cov ua npuas dej ntau dhau thiab cuam tshuam cov nyhuv huv. Yog li no, kev hloov kho kom tsim nyog ntawm HPMC concentration yog tus yuam sij los ua kom ntseeg tau qhov ruaj khov ntawm cov tshuaj ntxuav tes.
4.3 synergistic nyhuv nrog lwm cov kev sib ntxiv
HPMC feem ntau siv rau hauv kev sib txuas nrog lwm cov thickeners, stabilizers thiab surfactants. Piv txwv li, ua ke nrog hydrated silicates, ammonium chloride thiab lwm yam tshuaj, nws tuaj yeem txhim kho kev ua tau zoo tag nrho ntawm cov xab npum. Hauv cov kab ke no, HPMC ua si lub luag haujlwm tseem ceeb thiab tuaj yeem txhim kho kev ruaj khov thiab kev ua kom huv ntawm cov qauv.
HPMC Muaj peev xwm txhim kho lub cev thiab tshuaj muaj peev xwm ruaj khov ntawm cov tshuaj ntxuav ua kom tuab, stabilizer thiab ua npuas ncauj stabilizer nyob rau hauv detergents. Los ntawm kev xaiv tsim nyog thiab kev faib tawm, HPMC tsis tuaj yeem txhim kho cov rheology, ua npuas ncauj ntawm cov tshuaj ntxuav kom huv, tab sis kuj txhim kho lawv qhov kub tsis kam thiab tawv dej zoo yoog. Yog li ntawd, raws li ib qho tseem ceeb hauv xab npum, Kimacell® tus neeg muaj kev cia siab thiab kev txhim kho. Nyob rau hauv yav tom ntej kev tshawb fawb, yuav ua li cas thiaj ua kom zoo rau daim ntawv teev HPMC thiab ua kom tau qhov ruaj khov thiab ua tau zoo hauv cov ncauj lus kom tsim nyog ntawm kev tshawb nrhiav hauv kev tshawb nrhiav.
