Chii musiyano uripo pakatihydroxypruppropyl methylcellose(HPMC) ne kana pasina s?
1. HPMC yakakamurwa kuita rudzi rune rondedzero uye nekukurumidza kupararira mhando
HPMC inokurumidza kuparadzira mhando yakakwaniswa neiyo tsamba S. Munguva yekugadzira maitiro, Glyoxal inofanira kuwedzerwa.
HPMC Instant mhando haiwedzere chero mavara, senge "100000" iri "100000 viscossity nekukurumidza kuparadzira Type HPMC".
2. Ne kana pasina s, hunhu hwakasiyana
Kukurumidza kuparadzira HPMC inopararira nekukurumidza mumvura inotonhora uye inonyangarika mumvura. Panguva ino, mvura yacho haina viscosity, nekuti HPMC inongoparadzirwa mumvura, uye hapana kuputsika chaiko. Mushure memaminitsi matatu, iyo viscosity yemvura zvishoma nezvishoma inowedzera, inogadzira inonamira inonamira mvura. Gobvu colloid.
Pakarepo HPMC inogona kupararira nekukurumidza mumvura inopisa paanenge 70 ° C. Kana tembiricha ikadonha kune imwe tembiricha, iyo viscosity zvishoma nezvishoma inoonekwa kusvika kune yakajeka viscous colloid inoumbwa.
3. ne kana kana pasina s, chinangwa chakasiyana
Instant HPMC inogona kushandiswa chete mune putty poda uye dhaka. Mumvura glues, majasi uye zvekuchenesa, kukanda kuchaitika uye hakugone kushandiswa.
Kukurumidza kuparadzira HPMC ine huwandu hwakawanda hwekushandisa. Inogona kushandiswa muPutty poda, mongwe, mvura glue, pendi, uye yekugeza zvigadzirwa pasina chero kukanganisa.
Nzira yekunyungudika
1. Tora huwandu hunodiwa hwemvura inopisa, chiise mumudziyo uye uzvidzise kusvika kumusoro 80 ° C, uye zvishoma nezvishoma wedzera chigadzirwa ichi pasi pekunonoka kusimuka. Iyo cellulose inoyerera pamvura pakutanga, asi inopararira zvishoma nezvishoma kuti iite yunifomu slurry. Kutonhorera mhinduro nekumutsa.
2. Kana kupisa 1/3 kana 2/3 yemvura inopisa kusvika kumusoro 85 ° C, Wedzera Cellulose kuti uwane huwandu hwemvura inotonhora, ramba uchimutsa, uye kutonhorera musanganiswa unokonzeresa.
3. Cellulose ine huwandu hwakajeka huwandu, uye huripo seyakaenzana chidiki chidiki mumvura yakasimudzwa, uye inodonhedza nekukurumidza kana ichisangana nemvura kuti iite iyo inodiwa viscosity.

Ndezvipi zvinhu zvinokanganisa kuchengetedza kwemvura kwehydroxypruppropyl methylcellose?
Kuchengetwa kwemvura kwehydroxypropyl methylcellose hpmc chigadzirwa pachayo kunowanzo kukanganiswa nezvinhu zvinotevera:
1. Cellulose ether HPMC homogeneity
Iyo yakafanana yakagadziriswa HPMC ine yunifomu kugoverwa kweiyo nzira uye hydroxyprishipropopopoxy mapoka uye nekuchengetwa kwemvura yakakwira.
2. Cellulose ether Hpmc Thermal Gel tembiricha
Yakakwira iyo yekupisa ine tembiricha yekudziya, yakakwira yekuchengetedza mvura; Zvikasadaro, iyo yakadzika yekuchengetedza mvura chiyero.
3. Cellulose ether Hpmc viscossity
Kana visikopa yeHPMC ichiwedzera, iyo yekuchengetedza mvura inowedzerawo; Kana visikoka ichisvika pane imwe nhanho, kuwedzera kweiyo mwero wekuchengetedza mvura kunowanzoita zvinyoro nyoro.
Cellulose ether HPMC yekuwedzera huwandu
Iyo yakakura iyo huwandu hwakawedzerwa hwemasero ether hpmc, yakakwira iyo yekuchengetedza mvura chiyero uye zviri nani iyo yekuchengetedza mvura.
Muhuwandu hwe125-0.6%, iyo mvura yekuchengetwa kwemvura inowedzera nekukurumidza nekuwedzera kwekuwedzera huwandu; Kana kuwedzera kuwedzerwa kumwe kuwedzera, maitiro ekuwedzera eyekuwedzera kwemvura anozoita zvishoma nezvishoma.
