Yintoni uphawu lwe-viscosity ye-hydroxypropyl methyl cellulose isisombululo samanzi?
I-Hydroxypropyl methyl cellulose inethemba elibanzi kushishino lokwakha, kwaye iimpawu zayo ezigqwesileyo zokujiya kunye nokugcinwa kwamanzi zenza ukusetyenziswa kwayo kushishino lokwakha akunakuhoywa.Kodwa sazi kangakanani ngokugqwesa kwayo?Ngoku makhe sithethe malunga neempawu ze-viscosity ze-hydroxypropyl methyl cellulose isisombululo samanzi.
Hydroxypropyl methyl cellulose isisombululo aqueous Intshayelelo elula: IsiNgesi isifinyezo HPMC non-ionic, amanzi-ether cellulose enyibilikayo, imbonakalo emhlophe okanye ukukhanya umgubo omthubi okanye imathiriyeli granular.Imveliso yayo ayinancasa, ayinavumba, ingenatyhefu, izinzileyo yeekhemikhali zemveliso emanzini ukwenza ulwelo lwe-viscous olugudileyo.
Zeziphi izinto ezichaphazela i-viscosity ye-hydroxypropyl methyl cellulose isisombululo samanzi?
1.Ubudlelwane kunye ne-polymer: i-viscosity ye-hydroxypropyl methyl cellulose isisombululo samanzi silingana ne-polymer okanye ubunzima bemolekyuli, kwaye yonyuka ngokuphuculwa kwe-polymerization degree.Esi siphumo sibonakala ngakumbi kwimeko ye-polymerization ephantsi kunokuba kwimeko ye-polymerization ephezulu.
2.Ubudlelwane phakathi kwe-viscosity kunye nogxininiso: i-viscosity ye-hydroxypropyl methyl cellulose kwisisombululo esinamanzi inyuka ngokuxinwa kwesisombululo esinamanzi, kwaye kunye noshintsho oluncinci lwengxinano lunokubangela utshintsho olukhulu kwi-viscosity.
3.Ubudlelwane phakathi kwe-viscosity kunye ne-shear rate: Uvavanyo lubonisa ukuba i-hydroxypropyl methyl cellulose ayinalo utshintsho olubalulekileyo kwizinga eliphantsi lokucheba, kwaye i-viscosity iyancipha ngokunyuka kwezinga lokucheba.
4.Ubudlelwane phakathi kwe-viscosity kunye nobushushu: i-hydroxypropyl methyl cellulose ichaphazeleka kakhulu ngubushushu, kwaye i-viscosity iyancipha ngokunyuka kweqondo lokushisa.
5.Ezinye izinto: i-viscosity ye-hydroxypropyl methyl cellulose kunye nezongezo ezahlukahlukeneyo, izisombululo, ixabiso le-PH nalo linempembelelo.
Xa sisenza into yovavanyo lwaselebhu ekufuneka siyazi malunga ne-viscosity characteristicof hydroxypropyl methyl cellulose isisombululo samanzi?
