Yini ukuhlakanipha okufanelekile kwe-hydroxypropylylylylylyllose

I-Hydroxypropyllylylylyly ngokuvamile isetshenziswa ku-putty powder nge-100,000, kanti udaka unesidingo esiphezulu sensizwa, ngakho-ke kufanele isetshenziswe ngokubonakala kwabangu-150,000. Umsebenzi obaluleke kakhulu we-hydroxypropylllylylylylylyllose ingukugcinwa kwamanzi, kulandelwa ukuqina. Ngakho-ke, ku-putty powder, inqobo nje uma ukugcinwa kwamanzi kutholakala, ukubonakala kuphansi. Ngokuvamile, lapho kukhula khona i-viscosity, kungcono ukugcinwa kwamanzi, kepha lapho i-vistuant yeqa i-100,000, i-viscosity inomthelela omncane ekugcinweni kwamanzi.

Ngokusho kwe-viscosity, i-hydroxypropyl methylcellulose ihlukaniswe ngezinhlobo ezilandelayo:

1. I-Viscosity ephansi: I-400 viscosity cellule
Inokubonakala okuphansi nokwehla okuhle. Ngemuva kokungeza, kuzolawula ukugcinwa kwamanzi kobuso, ukopha akubonakali, i-shrinkage incane, ukuqhekeka kuncishisiwe, futhi kungamelana nokwenziwa kwe-filiment futhi kuthuthukise ukuncipha kanye nokuphazamiseka.

2. I-SAMENT ne-Low and Low
Ukubonakala okuphansi, ukugcinwa kwamanzi okuphezulu, ukusebenziseka okuhle, amanzi amancane angeziwe,

I-3. I-Medium Viscosity: 75,000-100,000 velcosity cellule
I-Viscosity Elinganiselayo, Ukugcinwa Okuhle Kwamanzi, Ukwakhiwa Okuhle Nokushintshana

4. I-Viscosity ephezulu: I-150,000-200,000, esetshenziselwa ikakhulukazi i-polystyrererese incration ukufakwa kodubule kwerabha, umhlobisi we-microbead wokufakelwa kwegciwane
Ngokubona okuphezulu nokugcinwa kwamanzi okuphezulu, udaka akulula ukulahla umlotha ne-sag, okuthuthukisa ukwakhiwa.

Ngokuvamile, kuphakama i-viscosity, okungcono ukugcinwa kwamanzi, amakhasimende amaningi azokhetha ukusebenzisa i-melcule-videose ephakathi (75,000-100,000) esikhundleni se-cellulosi ephakathi nendawo (20,000-50,000) ukuze anciphise inani elingeziwe, bese kulawula izindleko
