Ukukhetha i-HPMC Viscosity xa uvelisa isidanga somgubo oxubeneyo oxutywe?

I-Methyl Selelose MC kunye ne-HydroxylDollipyl Methyl Selelose (HPMC) enezindlu ezizinzileyo zeekhemikhali, ukuxhaswa kwe-nyibiw, kwaye azichaphazeleki zinguqu kwixabiso le-pH. Asikuko ukuba ukuphefumla, ngcono. I-vickosity ihambelana ngokuchaseneyo namandla ebhondi. Ukuphelisa i-viscofity, incinci amandla. Ukuveliswa komgubo we-putty ngokubanzi phakathi kwama-50 000 kunye ne-100,000 yeendwendwe. Ubukho bodaka lwangaphandle oluvuthayo oluxubileyo lulungele ngakumbi kwi-15 ukuya kwi-20,000 ye-viscosity, ikakhulu ukonyusa inqanaba kunye nolwakhiwo, inokunciphisa inani lesamente. Enye impembelelo kukuba udaka lwesamente lunethuba lokuqiniswa, apho kufuneka inyangwe kwaye amanzi kufuneka agcinwe emanzini. Ngenxa yemiphumo yokugcina amanzi e-seluplose, amanzi afunekayo ukuze umntu aqikelwe i-Creashing iqinisekisiwe ekugcinweni kwamanzi kwiselutase, ke isiphumo esiqingqiweyo sinokufezekiswa ngaphandle kolondolozo.

Ngokuphathelele umgangatho weselfowuni, ubukhulu becala i-viscofity, inokuvavanywa ngophawu lweyeza lokujikeleza, kwaye linokuthelekiswa nendlela elula. Xa uthelekisa, thatha igram enye yeselpulose nge-viscofity efanayo, yongeza iigram ezili-100 zamanzi, uyibeke kwindebe enye, kwaye uyigalele indawo ebonakalayo, kwaye inefuthe elingcono, kwaye linefuthe elingcono. Kungcono ukubonakala, ukungcola okuncinci.

I-carboxymethyl seluplose cmc kunye nesodium ye-carboxymethy starch (cms) iphantsi. Zisetyenziselwa umgubo wenqanaba eliphantsi eliphantsi kwiindonga zangaphakathi. Isetyenziselwe ukufaka imixube eyomileyo. Ngenxa yokuba ezi seluplose ziya kusabela nge-cemetion, i-calcium lime powder, i-gypsim powder, kunye neebhanti ze-inrganic.

Abantu abaninzi bacinga ukuba ezi zisele ziyiAlkaline. Ngokubanzi, isamente kunye ne-Calcium ye-calcium kunye ne-alkaline, kwaye bacinga ukuba banokusetyenziswa ngokudibeneyo. Nangona kunjalo, i-CMC kunye ne-CMS ayifani. I-chlorocetic acid esetyenzisiweyo kwinkqubo yemveliso iyi-acidic. Izinto ezisele kwinkqubo iphendula nge-clumes kunye ne-lime calcium powder, ke ayinakudityaniswa. Abavelisi abaninzi baye balahlekelwa yilahleko enkulu ngenxa yoku, kuqatshelwe ingqalelo.
