Hauv cov tshuaj ntxuav tes,HPMC (Hydroxypropyl Methylcellulose)yog ib qho thickener thiab stabilizer uas siv ntau. Nws tsis tsuas yog muaj cov nyhuv thickening zoo xwb, tab sis kuj txhim kho qhov fluidity, suspension thiab txheej ntawm cov tshuaj ntxuav tes. Yog li ntawd, nws yog siv dav hauv ntau yam tshuaj ntxuav tes, tshuaj ntxuav tes, tshuaj zawv plaub hau, da dej gels thiab lwm yam khoom. Qhov concentration ntawm HPMC hauv cov tshuaj ntxuav tes yog qhov tseem ceeb rau kev ua haujlwm ntawm cov khoom, uas yuav cuam tshuam ncaj qha rau cov nyhuv ntxuav, kev ua npuas ncauj, kev ntxhib los mos thiab kev paub ntawm tus neeg siv.
Lub luag haujlwm ntawm HPMC hauv cov tshuaj ntxuav tes
Cov nyhuv ua kom tuab: HPMC, ua ib qho thickener, tuaj yeem hloov qhov viscosity ntawm cov tshuaj ntxuav tes, yog li cov tshuaj ntxuav tes tuaj yeem sib npaug rau ntawm qhov chaw thaum siv, txhim kho cov nyhuv ntxuav. Tib lub sijhawm, qhov concentration tsim nyog pab tswj cov fluidity ntawm cov tshuaj ntxuav tes, ua rau nws tsis nyias dhau lossis viscous dhau, uas yooj yim rau cov neeg siv khoom siv.
Kev ruaj khov zoo dua: HPMC tuaj yeem txhim kho kev ruaj khov ntawm lub tshuab ntxuav thiab tiv thaiv kev sib cais lossis nag ntawm cov khoom xyaw hauv cov mis. Tshwj xeeb tshaj yog nyob rau hauv qee cov kua ntxuav thiab cov tshuaj ntxuav, HPMC tuaj yeem tiv thaiv kev tsis ruaj khov ntawm cov khoom thaum lub sijhawm khaws cia.
Txhim kho cov yam ntxwv ua npuas ncauj: Ua npuas ncauj yog ib qho tseem ceeb ntawm ntau yam khoom ntxuav. Qhov ntau ntawm HPMC tuaj yeem ua rau cov tshuaj ntxuav tsim cov npuas ncauj mos thiab kav ntev, yog li txhim kho cov txiaj ntsig ntxuav thiab kev paub ntawm cov neeg siv khoom.
Txhim kho cov khoom rheological: AnxinCel®HPMC muaj cov khoom rheological zoo thiab tuaj yeem kho qhov viscosity thiab fluidity ntawm cov tshuaj ntxuav tes, ua rau cov khoom du thaum siv thiab zam kom nyias dhau lossis tuab dhau.
Qhov zoo tshaj plaws concentration ntawm HPMC
Qhov concentration ntawm HPMC hauv cov tshuaj ntxuav yuav tsum tau hloov kho raws li hom khoom thiab lub hom phiaj ntawm kev siv. Feem ntau hais lus, qhov concentration ntawm HPMC hauv cov tshuaj ntxuav feem ntau yog nruab nrab ntawm 0.2% thiab 5%. Qhov concentration tshwj xeeb nyob ntawm cov hauv qab no:
Hom tshuaj ntxuav tes: Cov tshuaj ntxuav tes sib txawv muaj cov kev xav tau sib txawv rau HPMC concentration. Piv txwv li:
Cov tshuaj ntxuav kua: Cov tshuaj ntxuav kua feem ntau siv cov HPMC concentration qis dua, feem ntau yog 0.2% txog 1%. Qhov concentration ntawm HPMC ntau dhau yuav ua rau cov khoom nplaum dhau, cuam tshuam rau qhov yooj yim thiab kev siv yooj yim.
Cov tshuaj ntxuav uas muaj zog heev: Cov tshuaj ntxuav uas muaj zog heev yuav xav tau cov HPMC uas muaj zog ntau dua, feem ntau yog 1% txog 3%, uas tuaj yeem pab ua kom nws cov viscosity nce ntxiv thiab tiv thaiv kom tsis txhob muaj nag lossis daus ntawm qhov kub qis.
Cov tshuaj ntxuav ua npuas ncauj: Rau cov tshuaj ntxuav uas xav tau tsim ntau cov npuas dej, nce qhov concentration ntawm HPMC kom haum, feem ntau ntawm 0.5% thiab 2%, tuaj yeem pab txhim kho qhov ruaj khov ntawm cov npuas dej.
Cov kev xav tau kom tuab: Yog tias cov tshuaj ntxuav tes xav tau qhov viscosity siab tshwj xeeb (xws li cov tshuaj zawv plaub hau uas muaj viscosity siab lossis cov khoom siv ntxuav gel), yuav tsum muaj HPMC ntau dua, feem ntau ntawm 2% thiab 5%. Txawm hais tias qhov concentration siab dhau tuaj yeem ua rau qhov viscosity nce ntxiv, nws kuj tseem yuav ua rau muaj kev faib tawm tsis sib xws ntawm lwm cov khoom xyaw hauv cov mis thiab cuam tshuam rau kev ruaj khov tag nrho, yog li yuav tsum tau kho kom raug.
pH thiab kub ntawm cov mis: Qhov cuam tshuam ntawm HPMC ua kom tuab yog cuam tshuam nrog pH thiab kub. HPMC ua tau zoo dua hauv qhov chaw nruab nrab mus rau qhov tsis muaj zog alkaline, thiab qhov chaw acidic lossis alkaline ntau dhau yuav cuam tshuam rau nws lub peev xwm tuab. Tsis tas li ntawd, qhov kub siab dua yuav ua rau HPMC yaj ntau dua, yog li nws qhov kev sib xyaw yuav tsum tau kho hauv cov mis ntawm qhov kub siab.
Kev Sib Cuam Tshuam Nrog Lwm Cov Khoom Xyaw: AnxinCel®HPMC tej zaum yuav sib cuam tshuam nrog lwm cov khoom xyaw hauv cov tshuaj ntxuav tes, xws li surfactants, thickeners, thiab lwm yam. Piv txwv li, cov nonionic surfactants feem ntau sib xws nrog HPMC, thaum anionic surfactants tej zaum yuav muaj qee yam kev cuam tshuam rau qhov thickening effect ntawm HPMC. Yog li ntawd, thaum tsim cov mis, cov kev sib cuam tshuam no yuav tsum tau xav txog thiab qhov concentration ntawm HPMC yuav tsum tau kho kom haum.
Cov nyhuv ntawm kev sib xyaw ua ke ntawm kev ntxuav cov nyhuv
Thaum xaiv qhov concentration ntawm HPMC, ntxiv rau kev xav txog qhov thickening effect, qhov tseeb ntxuav ntawm cov tshuaj ntxuav tes yuav tsum tau coj mus rau hauv tus account. Piv txwv li, qhov concentration ntawm HPMC ntau dhau yuav cuam tshuam rau cov tshuaj ntxuav tes thiab cov yam ntxwv ua npuas ncauj, ua rau txo qis ntawm cov nyhuv ntxuav. Yog li ntawd, qhov concentration zoo tshaj plaws yuav tsum tsis yog tsuas yog xyuas kom meej tias muaj kev sib xws thiab fluidity, tab sis kuj xyuas kom meej tias muaj kev ntxuav zoo.
Cov ntaub ntawv tiag tiag
Kev siv rau hauv tshuaj zawv plaub hau: Rau cov tshuaj zawv plaub hau ib txwm, qhov concentration ntawm AnxinCel®HPMC feem ntau yog ntawm 0.5% thiab 2%. Yog tias muaj concentration ntau dhau, cov tshuaj zawv plaub hau yuav nplaum dhau, cuam tshuam rau kev nchuav thiab siv, thiab yuav cuam tshuam rau kev tsim thiab kev ruaj khov ntawm cov ua npuas ncauj. Rau cov khoom uas xav tau viscosity ntau dua (xws li tshuaj zawv plaub hau ntxuav tob lossis tshuaj zawv plaub hau), qhov concentration ntawm HPMC tuaj yeem nce ntxiv kom haum rau 2% txog 3%.
Cov tshuaj ntxuav ntau lub hom phiaj: Hauv qee cov tshuaj ntxuav ntau lub hom phiaj hauv tsev, qhov concentration ntawm HPMC tuaj yeem tswj tau ntawm 0.3% thiab 1%, uas tuaj yeem ua kom muaj kev ntxuav zoo thaum tswj cov kua dej kom zoo thiab cov nyhuv ua npuas ncauj.
Raws li ib tug thickener, qhov concentration ntawmHPMCHauv cov tshuaj ntxuav tes yuav tsum xav txog cov yam xws li hom khoom, cov kev xav tau ua haujlwm, cov khoom xyaw mis thiab kev paub ntawm tus neeg siv. Qhov concentration zoo tshaj plaws feem ntau yog nruab nrab ntawm 0.2% thiab 5%, thiab qhov concentration tshwj xeeb yuav tsum tau kho raws li qhov xav tau tiag tiag. Los ntawm kev ua kom zoo dua ntawm kev siv HPMC, qhov ruaj khov, fluidity thiab ua npuas ncauj ntawm cov tshuaj ntxuav tes tuaj yeem txhim kho yam tsis cuam tshuam rau kev ntxuav, ua tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv.
