1.Hpcyakakamurwa kuita kuti inyore mhando uye inokurumidza kupararira mhando.
Iyo HPMC inokurumidza kupararira mhando yakakwanira tsamba s, uye Glyoxal inofanira kuwedzerwa panguva yekugadzira maitiro.
HPMC Instant mhando haiwedzere chero mavara, se "100000" zvinoreva "100000 viscosity.
2. Ne kana pasina s, hunhu hwakasiyana
Kukurumidza kuparadzira HPMC kunopararira nekukurumidza kana kuchisangana nemvura inotonhora uye nekunyangarika mumvura. Panguva ino, iyo mvura haina viscosity, nekuti HPMC inongoparadzirwa mumvura pasina kupaza chaiko. Mushure memaminitsi matatu, iyo viscosity yemvura zvishoma nezvishoma inowedzera, ichigadzira iyo inoyera viscous gokodhi.
Instant HPMC inogona kukurumidza kuparadzirwa mumvura inopisa paanenge 70 ° C. Kana tembiricha ikadonha kune imwe tembiricha, iyo viscosity ichaonekwa zvishoma nezvishoma kusvika pane yakajeka viscous colloid inoumbwa.
3.With kana Pasina S, chinangwa chakasiyana
Instant HPMC inogona kushandiswa chete mune putty poda uye dhaka. Mumvura glue, pendi uye kugeza zvigadzirwa, pachave neboka chiitiko uye hazvigone kushandiswa.
Nekukurumidza kuparariraHpcine huwandu hwakawanda hwekushandisa uye hunogona kushandiswa mune putty poda, dhaka, mvura glue, pendi, uye yekugeza zvigadzirwa pasina chero kukanganisa.
4.Dissolving nzira
4-1. Tora huwandu hunodiwa hwemvura inopisa, chiise mumudziyo uye uzvidzise kusvika pamusoro 80 ° C, uye zvishoma nezvishoma wedzera ichi chigadzirwa chiri kusimudzana. Iyo cellulose inoyerera pane iyo mvura pakutanga, asi inopararira zvishoma nezvishoma kuti iite yunifomu slurry. Mhinduro yacho yakamanikidzwa uchimutsa.
4-2. Zvimwe, kupisa 1/3 kana 2/3 yemvura inopisa kusvika pamusoro 85 ° C, Wedzera Cellulose Kuti Utore Mvura inotonhora, ramba uchimutsa, uye kutonhorera musanganiswa unokonzeresa.
4-3. Iyo mesh yemheremello ndeyechokwadi, uye iripo sevanhu zvidiki zvidiki mumadhuku akasimbiswa, uye anodzungudza nekukurumidza kana ichisangana nemvura kuti iite iyo inodiwa viscosity.
4-4. Zvishoma nezvishoma uye zvichinyanyisa kuwedzera cellulose pamhepo tembiricha, uye ramba uchimutsa kusvikira mhinduro yechifananidzo ichiumbwa.
5.Zvinhu zvinokanganisa kuchengetwa kwemvura kwehydroxypropyl methyl cellulose?
5-1. Cellulose ether hpmc homogeneity
Chaizvoizvo akaitisa HPMC, madziridzo uye hydroxyprupoxyl anogoverwa zvakanyanya, uye huwandu hwemvura hwakakwira hwakakwira.
5-2. Cellulose ether hpmc thermal gel tembiricha
Yakakwira iyo yekupisa ine tembiricha yekudziya, yakakwira yekuchengetedza mvura; Zvikasadaro, iyo yakadzika yekuchengetedza mvura chiyero.
5-3. Cellulose ether Hpmc viscossity
Kana visikopa yeHPMC ichiwedzera, iyo yekuchengetedza mvura inowedzerawo; Kana visikoka ichisvika pane imwe nhanho, kuwedzera kwehuwandu hwemvura kuchinjika kunowanzove nyoro.
Mari 6.adDudition huwandu hwe cellulose ether hpmc
Iyo yakakura huwandu hwe cellulose etherHpcYakawedzerwa, iyo yakakwira iyo mvura yekuchengetwa kwemvura uye zviri nani iyo mvura yekuchengeta mvura.
Muhuwandu hwe1,25-0.6%, iyo mvura yekuchengetedza mvura yakawedzera nekukurumidza nekuwedzera kwekuwedzera mari; Kana kuwedzera kwehuwandu kuchiwedzera, kuwedzera kwemaitiro emvura yekuchengetedza mvura yakadzikira.
