Hydroxypropyl methyl cellulose, unoziva here?

1.HPMCrakakamurwa kuva pakarepo mhando uye kukurumidza kuparadzirwa mhando.

Iyo HPMC inokurumidza kuparadzira mhando inosungirirwa netsamba S, uye glyoxal inofanirwa kuwedzerwa panguva yekugadzira.

HPMC instant type haiwedzeri chero mavara, senge "100000" zvinoreva "100000 viscosity.

2. Iine kana isina S, maitiro akasiyana

Kukurumidza kuparadzira HPMC inopararira nekukurumidza kana yasangana nemvura inotonhora uye inonyangarika mumvura. Panguva ino, mvura haina viscosity, nokuti HPMC inongopararira mumvura pasina kuparara kwechokwadi. Mushure memaminitsi anenge maviri, viscosity yemvura inowedzera zvishoma nezvishoma, ichigadzira yakajeka viscous Thick colloid.

Instant HPMC inogona kuparadzirwa nekukurumidza mumvura inopisa kusvika 70°C. Kana tembiricha yadonha kune imwe tembiricha, iyo viscosity inozoonekwa zvishoma nezvishoma kusvika yakajeka viscous colloid yaumbwa.

3.With kana pasina S, chinangwa chakasiyana

Instant HPMC inogona kushandiswa chete mu putty poda uye dhaka. Mune glue yemvura, pendi uye zvigadzirwa zvekuwachisa, pachave nemapoka chiitiko uye hazvigone kushandiswa.

Kurumidza kuparariraHPMCine zvakasiyana-siyana zvekushandisa uye inogona kushandiswa mu putty poda, dhaka, liquid glue, pendi, uye zvigadzirwa zvekuwachisa pasina contraindications.

4.Dissolving nzira

4-1. Tora huwandu hunodiwa hwemvura inopisa, uiise mumudziyo uye inopisa kusvika pamusoro pe80 ° C, uye zvishoma nezvishoma uwedzere chigadzirwa ichi pasi pekugadzirisa zvishoma nezvishoma. Iyo cellulose inoyangarara pamusoro pemvura pakutanga, asi inoparadzirwa zvishoma nezvishoma kuita yunifomu slurry. Mushonga wacho wakatonhodzwa uchikurunga.

4-2. Zvimwewo, kupisa 1/3 kana 2/3 yemvura inopisa kusvika pamusoro pe85 ° C, wedzera cellulose kuti uwane slurry yemvura inopisa, wobva wawedzera yakasara yemvura inotonhora, ramba uchikurudzira, uye utonhodze musanganiswa unoguma.

4-3. Iyo mesh ye cellulose yakanaka, uye iripo sediki diki muhupfu hwakavhenganiswa, uye inonyungudika nekukurumidza kana yasangana nemvura kuti iite viscosity inodiwa.

4-4. Zvishoma nezvishoma uye zvakaenzana wedzera cellulose pane tembiricha yekamuri, uye ramba uchikurudzira kusvika mhinduro yakajeka yagadzirwa.

5.Ndezvipi zvinhu zvinokanganisa kuchengetwa kwemvura yehydroxypropyl methyl cellulose?

5-1. Cellulose ether HPMC homogeneity

Yakaenzana yakabatwa HPMC, methoxyl uye hydroxypropoxyl zvakagoverwa zvakaenzana, uye mwero wekuchengetedza mvura wakakwira.

5-2. Cellulose ether HPMC thermal gel tembiricha

Iyo yakakwirira tembiricha yekudziya gel, iyo yakakwirira yekuchengeta mvura; kana zvisina kudaro, iyo yakaderera mwero wekuchengetedza mvura.

5-3. Cellulose Eteri HPMC Viscosity

Kana viscosity yeHPMC ichiwedzera, chiyero chekuchengetedza mvura chinowedzerawo; apo viscosity inosvika kune imwe nhanho, kuwedzera kwehuwandu hwekuchengetedza mvura kunowanzova munyoro.

6.Kuwedzera huwandu hwe cellulose ether HPMC

Iyo yakakura kuwanda kwe cellulose etherHPMCyakawedzera, iyo yakakwirira yehuwandu hwekuchengetwa kwemvura uye zviri nani kuchengetedza kwemvura.

Muchikamu che 0.25-0.6%, chiyero chekuchengetedza mvura chakawedzera nokukurumidza nekuwedzera kwekuwedzera kwekuwedzera; apo huwandu hwekuwedzera hunowedzera kuwedzera, kuwedzera kwemaitiro ekuchengetwa kwemvura kwakaderera.
