Physicochemical Property
1. Kuonekwa: hupfu chena, kwete kunhuwa uye kunakidza.
2. Granularity: mwero wekupasa kwe100 wapinda mukuru kupfuura 98.5%;the pass rate of 80 entries yakakura kudarika 100%.
3. Carboization tembiricha: 280-300 ℃.
4. Kuwanda kwepamusoro: 0.25-0.70g / cm3(Kazhinji pa 0.5g / cm3Kuruboshwe uye kurudyi), pamwe nechikamu che1.26-1.31.
5. Discolored color tembiricha: 190-200℃.
6. Kushungurudzika kwepamusoro: Pa25 ℃, iyo 2% yemvura inogadzirisa ndeye 42-56dyn / cm.
7. Solubility: yakanyungudutswa mumvura uye mamwe organic solvents, akadai sechikamu chakakodzera che ethanol / mvura, propane doro / mvura, dioxethane, etc.Aqueous solutions ine basa repamusoro, kujeka kwepamusoro uye kugadzikana kwekushanda.Kunyunguduka kunosiyana neine viscosity.Iyo yakaderera iyo viscosity, iyo yakanyanya kunyungudika, kuita kweHPMC kunosiyana pakati pezvakasiyana zvirevo, uye kutaridzika kunyungudika kweHPMC mumvura hakukanganiswe neiyo pH kukosha.
8. HPMC inodzikira ine methoxy content, yakawedzera gel point, kuderera kwekunyungudika kwemvura, uye zvakare kuderera kwekuita kwepamusoro.
9. HPMC inewo kukwanisa kwekukora, kuderera kwe grey salt discharge, pH kugadzikana, kuchengetedza mvura, yakanakisa membranogenesis, pamwe nehupamhi hwekudzivirira kwe enzyme, kupararira uye kunamatira.
10. Chiitiko chepamusoro: The HPMC aqueous solution ine surfactant function, uye inogona kushandiswa se colloidal inodzivirira agent, emulsifier uye dispersant.
11. Thermal gel: Kana iyo HPMC aqueous solution ichidziya kune imwe tembiricha, inova isina kujeka.Iyo gel inoumba kunaya kwemvura, asi mukutonhora kunoramba kuripo, inodzokera kune yekutanga mhinduro mamiriro.Uye tembiricha iyo iyo gel uye kunaya kwemvura kunoitika kunoenderana zvakanyanya nemhando yavo, kutarisisa, uye kupisa mwero.
12. pH kugadzikana: The viscosity yeHPMC aqueous solution inenge isina kukanganiswa neasidhi kana chigadziko, uye pH inokosha inenge yakagadzikana muhuwandu hwe 3.0-11.0. Nokudaro, viscosity yemhinduro inogadzikana panguva yekuchengetedza kwenguva refu. .
13. Kuchengetedzwa kwemvura: HPMC inyanzvi yekuchengetedza mvura.Zvigadzirwa zvinoshandiswa zvakanyanya mukuvaka, chikafu, zvizoro, uye zvimwe zvakawanda.
14. Membranicity: HPMC inogona kuumba yakajeka, yakaoma uye inoshanduka yakaonda firimu iyo inogona zvakanakisa kudzivirira kupinza kwemafuta.Kushandisa muzvokudya, pfuma iyi inowanzoshandiswa kuchengetedza mvura munguva yekutonhora uye adsorbed mafuta.
15. Kusunga: Inogona kushandiswa seanonamatira kune pigment, pendi uye pepa, asiwo mupende nekunamatira.
