Iyo yekushandisa nzira ye cellulose ether uye kushanda kwayo muvhu rakaoma dhaka

Maitiro ekushandisa cellulose ether
Fast Dissolving:
1. Pasi pekusimudzira kunoramba kuripo, HPMC inonyungudika mumvura uye mamwe ma organic solvents, akadai sekukurumidza kupera.Yakakurudzirwa nzira:
(1) Shandisa mvura inopisa pamusoro pe80 ° C kuti zvishoma nezvishoma uwedzere chigadzirwa ichi pasi pekuenderera mberi kwekukurudzira.Iyo cellulose inoparadzirwa zvishoma nezvishoma mumvura uye inova slurry yakazvimba.Kurudzira uye kutonhorera kusvikira mhinduro yava pachena, zvinoreva kuti yakanyungudika zvachose.
(2) Pisa inenge hafu yemvura inodiwa kusvika pamusoro pe80 ° C, wedzera chigadzirwa ichi nekuenderera mberi uchikurudzira kuti uwane slurry, wedzera huwandu hwasara hwemvura inotonhora, uye simbisa kusvika pachena.
2. Shandisa mushure mekugadzira porridge-rakafanana naamai doro:
Kutanga gadzira HPMC muhuwandu hwepamusoro hweporridge-saamai doro redoro (iyo nzira yakafanana neyepamusoro kune madhaka slurry).Paunenge uchiishandisa, wedzera mvura inotonhora uye ramba uchikurudzira kusvika yave pachena.

Kuita kwe cellulose ether mune yakaoma poda dhaka

Cellulose ether ine yakanakisa kuchengetedza mvura mudhaka, iyo inogona kunyatso kudzivirira dhaka kubva pakuoma uye kuputika nekuda kwekurasikirwa kwemvura nekukurumidza, kuitira kuti dhaka rive nenguva yakareba yekuvaka.
Iko kukora mhedzisiro ye cellulose ether inogona kudzora yakanyanya kuenderana yemugwagwa wedhaka, kuvandudza kubatana kwedhaka, kuwana iyo anti-sag mhedzisiro, kuvandudza kushanda, uye kuwedzera zvakanyanya kushanda kwekuvaka.
Cellulose ether inogona kuvandudza zvakanyanya kunyorova viscosity yedhaka rakanyorova uye kuve nechokwadi chekuti dhaka rakanyorova rine hukama hwakanaka hwekubatanidza pane akasiyana substrates.
Iyo yakanyanya kunatsiridza bond simba re cellulose ether inogona kuve nechokwadi chemvura yakakwana kunyangwe mukupisa kwakanyanya nharaunda, kuitira kuti simende igove yakazara hydrated, nokudaro kuve nechokwadi kusungirirwa kuri nani kwedhaka.
Cellulose ether ine imwe air-entraining basa kuti iwedzere kubuda kwedhaka.
