1. HPMC yakakamurwa kuva pakarepo mhando uye nokukurumidza kuparadzira mhando.
HPMC yekukurumidza dispersion mhando ine vara S sechivakashure.Glyoxal inofanira kuwedzerwa panguva yekugadzira.
HPMC inokurumidza-kuparadzira mhando haiwedzeri chero mavara, senge "100000" zvinoreva "100000 viscosity inokurumidza-kuparadzira HPMC".
2. Iine kana isina S, maitiro akasiyana
Inokurumidza kuparadzira HPMC inokurumidza kupararira mumvura inotonhora uye inonyangarika mumvura.Iyo mvura haina viscosity panguva ino nekuti HPMC inongopararira mumvura uye haina kunyungudika chaizvo.Mushure memaminitsi maviri, viscosity yemvura inowedzera zvishoma nezvishoma, ichigadzira sparent viscous liquid.Gobvu colloid.
Instant HPMC inogona kuparadzirwa nekukurumidza mumvura inopisa pa70°C.Kana tembiricha yadonha kusvika kune imwe tembiricha, viscosity inooneka zvishoma nezvishoma kusvika yakajeka viscous colloid yaumbwa.
3. Iine kana isina S, chinangwa chakasiyana
Instant HPMC inogona kushandiswa chete mu putty poda uye dhaka.Mumvura glues, pendi uye zvinhu zvekuchenesa, clumps inogona kuitika uye isingagoneki.
Inokurumidza kuparadzira HPMC ine huwandu hwakawanda hwekushandisa.Inogona kushandiswa kune putty poda, dhaka, mvura glue, pendi, uye yekuchenesa zvinhu pasina contraindications.
dissolution nzira
1. Tora huwandu hunodiwa hwemvura inopisa, uiise mumudziyo uye upise kusvika pamusoro pe80 ℃, uye zvishoma nezvishoma uwedzere chigadzirwa ichi nekunonoka.Iyo cellulose inoyangarara pamusoro pemvura pakutanga, asi zvishoma nezvishoma inopararira kuita yunifomu slurry.Itonhodze mushonga uchikurunga.
2. Kana kupisa 1/3 kana 2/3 yemvura inopisa kusvika pamusoro pe85 ° C, wedzera cellulose kuti uwane slurry yemvura inopisa, wobva wawedzera mvura yakasara yemvura inotonhora, funganya nguva dzose, uye utonhorere musanganiswa unoguma.
3. Cellulose ine mesh ine saizi yakanaka uye iripo sediki diki diki muupfu hwakakanyiwa hwakafanana.Inonyungudika nekukurumidza kana yaiswa mumvura kuti iite viscosity inodiwa.
4. Wedzera cellulose zvishoma nezvishoma uye zvakaenzana pakushambidzika kwekamuri, uchikurudzira nguva dzose kusvikira mhinduro yakajeka mafomu.
Ndezvipi zvinhu zvinokanganisa kuchengetwa kwemvura kwehydroxypropyl methylcellulose?
Kuchengetwa kwemvura kwehydroxypropyl methylcellulose HPMC zvigadzirwa pachayo kunowanzo kukanganiswa nezvinhu zvinotevera:
1. Homogeneity ye cellulose ether HPMC
Iwo akafanana akaitwa HPMC methoxy uye hydroxypropoxy mapoka akagovaniswa zvakaenzana uye ane yakakwirira kuchengetwa kwemvura.
2. Cellulose ether HPMC thermal gel tembiricha
Iyo yakakwirira tembiricha ye thermal conductive gel, iyo yakakwirira yehuwandu hwekuchengetedza mvura;ukuwo, iyo yakaderera mwero wekuchengetedza mvura.
3. Viscosity ye cellulose ether HPMC
Kana viscosity yeHPMC ichiwedzera, chiyero chekuchengetedza mvura chinowedzerawo;apo viscosity inosvika kune imwe nhanho, kuwedzera kwehuwandu hwekuchengetedza mvura kunowanzova munyoro.
Cellulose ether HPMC yekuwedzera huwandu
Iyo yakakura huwandu hweselulosi ether HPMC yakawedzerwa, iyo yakakwirira yehuwandu hwekuchengetedza mvura uye zvirinani mhedzisiro yekuchengeta mvura.
Muchikamu che 0.25-0.6%, chiyero chekuchengetedza mvura chinowedzera nokukurumidza sezvo mari yekuwedzera inowedzera;apo huwandu hwekuwedzera hunowedzera kuwedzera, kuwedzera kwemaitiro ekuchengetwa kwemvura kunononoka.
