Uyisebenzisa njani i-cellulose ether
Ukunyibilika ngokukhawuleza:
1. Ngaphantsi kokuvuselela okuqhubekayo, i-HPMC inyibilika emanzini kunye nezinye izinyibilikisi ze-organic, ezifana nokuchithwa ngokukhawuleza.Indlela ecetyisiweyo:
(1) Sebenzisa amanzi ashushu ngaphezu kwe-80 ° C ukongeza ngokuthe ngcembe le mveliso phantsi kokuvuselela okuqhubekayo.I-cellulose ichithwa kancinci emanzini kwaye ibe ludaka oludumbileyo.Gxuma kwaye upholile de isisombululo sibonakale, oku kuthetha ukuba ichithwe ngokupheleleyo.
(2) Fudumeza malunga nesiqingatha somthamo ofunekayo wamanzi ukuya ngaphezu kwe-80 ° C, yongeza le mveliso ngokuvuselela ngokuqhubekayo ukuze ufumane i-slurry, yongeza inani eliseleyo lamanzi abandayo, kwaye udibanise kude kube sobala.
2. Sebenzisa emva kokwenza utywala obufana nesidudu:
Okokuqala yenza i-HPMC ibe luxinaniso oluphezulu lotywala obufana nesidudu (indlela iyafana nale ingasentla ukuya eludaka oludaka).Xa uyisebenzisa, yongeza amanzi abandayo kwaye uqhubeke uvuselela de ibonakale.
Ukusebenza kwe-cellulose ether kwi-powder mortar eyomileyo
I-ether ye-cellulose inokugcinwa kwamanzi okugqwesileyo kwi-mortar, enokuthintela ngokufanelekileyo udaka ukuba lome kwaye luqhekeke ngenxa yokulahlekelwa kwamanzi ngokukhawuleza, ukwenzela ukuba udaka lunexesha elide lokwakha.
Isiphumo esityebileyo se-cellulose ether inokulawula eyona ndlela ilungileyo yendlela yodaka, iphucule ukudityaniswa kodaka, ifezekise isiphumo sokulwa ne-sag, iphucule ukusebenza, kwaye yandise kakhulu ukusebenza kakuhle kolwakhiwo.
I-ether ye-cellulose inokuphucula kakhulu i-viscosity emanzi yodaka olumanzi kwaye iqinisekise ukuba udaka olumanzi lunefuthe elihle lokudibanisa kwii-substrates ezahlukeneyo.
Amandla ebhondi ephuculweyo ye-cellulose ether inokuqinisekisa amanzi aneleyo nakwimekobume yobushushu obuphezulu, ukwenzela ukuba isamente ibe ne-hydrated ngokupheleleyo, ngaloo ndlela iqinisekisa ukubonda okungcono kodaka.
I-ether ye-cellulose inomsebenzi othile wokungenisa umoya wokunyusa ukuveliswa kodaka.
