Izinto ezininzi eziphambili ezichaphazela ukugcinwa kwamanzi kwi-hydroxypropyl methylcellulose

I-Hydroxypropyl methylcellulose (HPMC) yi-ether ye-cellulose engeyiyo ionic eyenziwe kwi-cellulose yezinto ze-polymer yendalo ngokusebenzisa uchungechunge lweenkqubo zemichiza. Azinavumba, azinancasa kwaye zingumgubo omhlophe ongenatyhefu othi udumbe ube sisinyibiliko esicacileyo okanye esinamafu kancinane kwi-colloidal kumanzi abandayo. Inokuqina, ukubopha, ukusabalalisa, i-emulsifying, ifilimu-ifom, ukumisa, i-adsorbing, i-gelling, i-surface esebenzayo, igcina umswakama kunye neempawu ze-colloid ezikhuselayo. I-Hydroxypropyl methyl cellulose kunye ne-methyl cellulose ingasetyenziselwa kwizinto zokwakha, imboni yepeyinti, i-resin yokwenziwa, i-ceramic industry, iyeza, ukutya, i-textile, ezolimo, iikhemikhali zemihla ngemihla kunye namanye amashishini.

Ukugcinwa kwamanzi kwe-hydroxypropyl methylcellulose HPMC imveliso ngokwayo ihlala ichatshazelwa zezi zinto zilandelayo:

1. Ubungakanani be-hydroxypropyl methylcellulose HPMC eyongeziweyo Ubuninzi be-cellulose ether HPMC eyongeziweyo, iphezulu izinga lokugcinwa kwamanzi kunye nesiphumo esingcono sokugcinwa kwamanzi. Kuluhlu lwe-0.25-0.6% yokongezwa, izinga lokugcinwa kwamanzi landa ngokukhawuleza ngokunyuka kwexabiso elongezelelweyo; xa isixa-mali esongeziweyo sinyuka ngakumbi, ukunyuka kwezinga lokugcinwa kwamanzi kuyehla.

2. I-HPMC viscosity ye-hydroxypropyl methylcellulose Xa i-viscosity ye-HPMC inyuka, izinga lokugcinwa kwamanzi nalo liyenyuka; xa i-viscosity ifikelela kwinqanaba elithile, ukunyuka kwezinga lokugcinwa kwamanzi kuthanda ukuba mnene.

3. I-Hydroxypropyl methylcellulose I-HPMC yobushushu be-thermal gel Ubushushu obuphezulu be-thermal gel, izinga eliphezulu lokugcina amanzi; kungenjalo, izinga lokugcinwa kwamanzi aphantsi.

4. I-Hydroxypropyl methylcellulose HPMC homogeneity HPMC kunye ne-uniform reaction, i-methoxyl kunye ne-hydroxypropoxyl zisasazwa ngokulinganayo, kwaye izinga lokugcinwa kwamanzi liphezulu.
