3,chigadzirwa chimiro
Properties: Ichi chigadzirwa ichena kana isina-chena poda, isina kunhuhwirira, isina kunaka uyenon-chepfu.
Kunyungudika kwemvura uye kugona kukora: Ichi chigadzirwa chinogona kunyungudutswa mumvura inotonhora kuti igadzire yakajeka viscous mhinduro.
Dissolution in organic solvents: Nekuti ine huwandu hwemapoka ehydrophobic methoxyl, chigadzirwa ichi chinogona kunyungudika mune mamwe organic solvents, uye chinogona zvakare kunyungudika muzvinonyungudutsa zvakasanganiswa nemvura uye organic zvinhu.
Kuramba munyu: Sezvo chigadzirwa ichi chiri chisiri-ionic polymer, chakanyatsogadzikana muminyungururo ine aqueous yesimbi munyu kana organic electrolytes.
Chiitiko chepamusoro: Mhinduro ine mvura yechigadzirwa ichi ine chiitiko chepamusoro, uye ine mabasa uye zvimiro zvakaita se emulsification, inodzivirira colloid uye kugadzikana kwehukama.
Thermal gelation: Kana iyo aqueous solution yechigadzirwa ichi ichipisa kune imwe tembiricha, inova opaque kusvika yaita (poly) flocculation state, kuitira kuti mhinduro irase viscosity yayo.Asi mushure mekutonhora, inoshanduka kuita yekutanga mhinduro mamiriro zvakare.Iko kutonhora kunoitika gelation kunoenderana nerudzi rwechigadzirwa, kusangana kwemhinduro uye chiyero chekupisa.
PH kugadzikana: The viscosity yeaqueous solution yechigadzirwa ichi yakagadzikana mukati mehuwandu hwePH3.0-11.0.
Mvura-yekuchengetedza maitiro: Sezvo chigadzirwa ichi chiri hydrophilic, chinogona kuwedzerwa kune dhaka, gypsum, pendi, nezvimwewo kuchengetedza yakakwira-yekuchengetedza mvura muchigadzirwa.
Kuchengetwa kwechimiro: Kuenzaniswa nemamwe mapolima anonyungudika nemvura, mhinduro ine mvura yechigadzirwa ichi ine yakakosha viscoelastic zvivakwa.Kuwedzera kwayo kune kugona kuchengetedza chimiro che extruded ceramic zvigadzirwa zvisina kuchinjwa.
Lubricity: Kuwedzera chigadzirwa ichi kunogona kuderedza friction coefficient uye kunatsiridza lubricity ye extruded ceramic zvigadzirwa uye simende zvigadzirwa.
Mafirimu-ekugadzira zvimiro: Ichi chigadzirwa chinogona kuumba inochinjika, yakajeka firimu ine yakanakisa mechaniki zvivakwa, uye ine yakanaka mafuta uye mafuta kuramba.
4.Zvenyama uye zvemakemikari zvinhu
Particle size: 100 mesh pass rate yakakura kupfuura 98.5%, 80 mesh pass rate i100%

Solubility: Inonyungudika mumvura uye zvimwe zvinonyungudutsa, iyo aqueous solution ine basa repamusoro.High transparency.Kuita kwakagadzikana, solubility inoshanduka ne viscosity, iyo yakaderera iyo viscosity, iyo yakakura solubility.
HPMC zvakare ine hunhu hwekukora, kuramba munyu, kugadzikana kwePH, kuchengetedza mvura, kugadzikana kwedimensional, yakanakisa kugadzira firimu pfuma, uye huwandu hwakasiyana hwekupokana kwe enzyme, dispersibility uye kubatana.
5, chinangwa chikuru
Industrial giredhi HPMC inonyanya kushandiswa seanoparadzira mukugadzirwa kwepolyvinyl chloride, uye ndiyo inonyanya kubatsira mumiriri wekugadzirira PVC nekumisa polymerization.Uye zvakare, inogona kushandiswa seyakakora, stabilizer, emulsifier, excipient, uye mvura-inochengetedza mumiriri mukugadzirwa kwemamwe petrochemicals, machira, zvekuvakisa, kubvisa pendi, makemikari ekurima, ingi, kudhinda machira uye dhayi, ceramics, bepa. , cosmetics, etc. , film forming agent, etc. Iko kushandiswa mumasikisi ekugadzira kunogona kuita kuti zvigadzirwa zvakawanikwa zvive nemaitiro ezvimedu zvenguva dzose uye zvakasununguka, zvakakodzera zvakananga giravhiti uye kushanda kwakanakisisa kwekugadzirisa, nokudaro kutsiva gelatin uye polyvinyl doro sevanoparadzira.
Nzira nhanhatu dzekugadzirisa:
(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.
(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.
(3).Iyo mesh ye cellulose yakanaka, uye iripo sediki diki muhupfu hwakavhenganiswa, uye inonyungudika nekukurumidza kana yasangana nemvura kuti iite viscosity inodiwa.
(4).Zvishoma nezvishoma uye zvakaenzana wedzera cellulose pane tembiricha yekamuri, ichikurudzira nguva dzose kusvikira mhinduro yakajeka yagadzirwa.
