Umthamo wokugcina amanzi we-hydroxypropyl methylcellulose uxhomekeke kumthamo we-hydroxypropyl. Phantsi kweemeko ezifanayo, umthamo wokugcina amanzi we-hydroxypropyl methylcellulose ephezulu unamandla, kwaye umxholo we-methoxy womxholo ofanayo we-hydroxypropyl uncitshiswa ngokufanelekileyo. . Okukhona umxholo we-hydroxypropyl methylcellulose uphezulu, kokukhona i-viscosity yayo iba nkulu, ngoko ke xa ukhetha imveliso, kufuneka ukhethe imveliso ekufaneleyo ngokwenjongo yemveliso.
Ubushushu kunye nezinye izinto zinefuthe ekugcinweni kwamanzi kwe-hydroxypropyl methylcellulose.
Ubushushu bejeli eshushu:
I-cellulose ether HPMC inobushushu obuphezulu bokufudumeza kunye nokugcinwa kakuhle kwamanzi; ngokuchaseneyo, ayinawo amanzi aneleyo.
Ukuqaqamba kwe-cellulose ether HPMC:
Xa i-viscosity ye-HPMC isanda, ukugcinwa kwamanzi kwayo kuyanda; xa i-viscosity isanda ukuya kwinqanaba elithile, ukwanda kokugcinwa kwamanzi kuyancipha.
I-cellulose ether HPMC iyafana:
I-HPMC inempendulo efanayo, isasazwa ngokufanayo kwe-methoxyl kunye ne-hydroxypropoxyl, kwaye inokugcina amanzi kakuhle.
Idosi ye-HPMC ye-cellulose ether:
Okukhona umthamo uphezulu, kokukhona izinga lokugcinwa kwamanzi liphezulu kwaye kokukhona isiphumo sokugcinwa kwamanzi sibonakala ngakumbi.
Xa isixa sokongeza siyi-0.25 ~ 0.6%, izinga lokugcina amanzi liyanda ngokukhawuleza ngokonyuka kwesixa sokongeza; xa isixa sokongeza sisanda ngakumbi, umkhwa wokwanda kwesixa sokugcina amanzi uyehla.
Ngamafutshane, ukugcinwa kwamanzi kwe-HPMC kunxulumene nezinto ezifana nobushushu kunye ne-viscosity, kwaye ukugcinwa kwamanzi kwayo kunxulumene nobungakanani be-hydroxypropyl methylcellulose eyongeziweyo. Xa ubungakanani be-hydroxypropyl methylcellulose bufikelela kwixabiso elithile, ukusebenza kwayo kokugcinwa kwamanzi kufikelela kwibhalansi.
