Kushanda Kwekushandisa kweHPMC
Hydroxypropyl methyl cellulose (HPMC) imhando yeasiri-ionic cellulose ether, iyo inogadzirwa neakasikwa polymer zvinhu seyakagadzirwa uye inonatswa nekutevedzana kwemakemikari maitiro. Nhasi tichadzidza nezve mashandiro ekushandisa kweHPMC.
● Kunyungudika kwemvura: inogona kunyungudutswa mumvura mune chero chikamu, iyo yepamusoro-soro inobva pane viscosity, uye kuparara hakugadziriswi nePH.l Organic solubility: HPMC inogona kunyungudutswa mune mamwe organic solvents kana organic solvent aqueous solutions yakadai se dichloroethane, ethanol solution, nezvimwewo.
● Thermal gel maitiro: Reversible gel ichaonekwa kana mhinduro yavo yeaqueous ichipisa kune imwe tembiricha, ine inodzoreka inokurumidza-kuseta kuita.
● Hapana ionic charge: HPMC is non-ionic cellulose ether uye haizoomeseki nemaoni esimbi kana organics kuti iumbe inseluble precipitates.
● Kukora: Mushonga wayo wemvura une kukora, uye kukobvuta kwacho kunoenderana nekunakigwa kwayo, kutarisisa, uye hurongwa.
● Kuchengeta mvura: HPMC kana mhinduro yayo inogona kutora uye kuchengetedza mvura.
● Magadzirirwo emufirimu: HPMC inogona kugadzirwa kuita yakatsetseka, yakaoma, uye elastic firimu, uye ine yakanakisa girizi uye oxidation kuramba.
● Enzyme kuramba: Mhinduro yeHPMC ine yakanakisa enzyme kuramba uye yakanaka viscosity kugadzikana.
● PH kugadzikana: HPMC inenge yakagadzikana kune asidi uye alkali, uye pH haina kukanganiswa muhuwandu hwe3-11. (10) Chiitiko chepamusoro: HPMC inopa chiitiko chepamusoro mumhinduro kuti uwane inodiwa emulsification uye inodzivirira colloid mhedzisiro.
● Anti-sagging pfuma: HPMC inowedzera system thixotropic zvinhu kune putty powder, dhaka, tile glue, uye zvimwe zvigadzirwa, uye ine yakanakisa anti-sagging kugona.
● Dispersibility: HPMC inogona kuderedza kuwirirana kwepakati pakati pezvikamu uye kuita kuti chikamu chakapararira chakapararira chakafanana mumadonhwe ehukuru hwakakodzera.
● Adhesion: Inogona kushandiswa sebhainda repigment density: 370-380g/l³ bepa, uye inogonawo kushandiswa mukuputira uye kunamira.
● Lubricity: Inogona kushandiswa murubha, asbestos, simende, uye zvigadzirwa zveceramic kuderedza kukwesha uye kunatsiridza kupinda kwekongiri slurry.
● Kumiswa: Inogona kudzivirira zvimedu zvakagadziriswa kubva pakunaya uye kudzivisa kuumbwa kwemvura.
● Emulsification: Nokuti inogona kuderedza pamusoro uye kupindirana kwechiso, inogona kudzikamisa emulsion.
● Protective colloid: Chidziviriro chekudzivirira chinoumbwa pamusoro pemadonhwe akapararira kudzivirira madonhwe kubva pakubatana uye agglomerating kuti awane simba rekudzivirira rakagadzikana.
