Kuvaka Kuvaka Giredhi (HPMC) Hydroxypropyl methyl cellulose
Yakasanganiswa cementitious dhaka rave chikamu chakakosha cheindasitiri yedhaka muGlobal uye vanoita basa risingaite nekuda kwekusimudzirwa kwemusika uye rutsigiro rwenyika.Mukugadzirwa kwematope, cellulose ether ndeye animeal activist.
Ordinary dhaka iri kudiwa mune zvehupfumi mune iyo simende level idiki, asi zvinodiwa zvekushandisa kwayo uye michina yekupfapfaidza zvivakwa zvichiri zvakakwirira, saka jecha grading uye additives zvakakosha.Uye zvakare, mechanical application inove yakasarudzika tsika yekuvandudza yakagadzirira-yakasanganiswa dhaka, cellulose ether ichaita kuti mechanical application igoneke.
Product Features
Wedzera kudiwa kwemvura.
Kuchengetedzwa kwemvura kwakakwirira, kurebesa nguva yekushanda kwezvinhu, kunatsiridza mashandiro ekushanda, kudzivirira chiitiko checrusting, uye kubatsira kuvandudza simba remagetsi rezvinhu.
Kuvandudzwa kwekushanda kwekushanda, kupa lubrication uye yunifomu texture, kuitira kuti pamusoro pezvinhu zvive nyore kupukuta, nokudaro kuvandudza kushanda kwekuvaka, uye kuvandudza kupikisa kwekuputika kweputty.
Kuvandudza homogeneity, uye kunatsiridza vertical kuyerera kuramba.
HPMC yekunamatira mataira
Ceramic mataira ane hunyanzvi hwekuita uye yakanakisa kushanda zvakanaka kana yakanamatira pane akasiyana substrates.Skid kuramba uye zvirinani kuvhura nguva ndiyo kiyi yekunamira zvirinani zvinodiwa.
HPMC yemadziro putty
HPMC isiri-ionic cellulose ether yakagadzirwa kubva kune yakasikwa fiber fiber pasi peyakatevedzana yemakemikari kugadzirisa.Haina kunhuhwirira, isinganakidze uye isina chepfu chena poda, inogona kunyungudutswa mumvura yakajairika kuti igadzire yakajeka viscous mhinduro ine zvimiro zvekukora, kusunga, kuparadzira, emulsifying, kupfeka firimu, kumisa, kutora, gelling, kuchengetedza mvura uye kudzivirira kwecolloid.
cellulose ethers inopa zvinotevera zvakanaka zvivakwa kune dhaka:
一Optimized wetting kugona kune substrate
一 Yepamusoro pekuchengetedza mvura kugona
一 kupfapfaidza kwakanaka nekupomba kuita
一 Kuvandudza simende hydration nekubatanidza simba
Product Description
1) Chitarisiko: HPMC is nonionic cellulose ether, chena greyish-white powder kana granule, isina kunhuhwirira uye isina kunaka, inonyungudika mumvura inotonhora, glacial acetic acid, ethanol, methanol uye propylene glycol, inonyungudika zvishoma muacetone zvichienderana nehuwandu hwekutsiva, inenge isinganyungudike mumvura inopisa, ethylene glycol uye toluene.HPMC inonyungudika mumusanganiswa we10% methanol uye 90% methylene chloride kuita colloidal mhinduro.
2) Mhinduro yeHPMC ine chiitiko chepamusoro, kujeka kwepamusoro, uye kuita kwakagadzikana.Kana ichipisa pane imwe tembiricha, mhinduro inova nemakore kana kuumba flocculent gel.Zvisinei, mhinduro inova yakajeka zvakare mushure mekutonhora.Mhando dzakasiyana dzeHPMC dzine tembiricha dzakasiyana dzegelation.Iyo solubility inosiyana ne viscosity.Iyo yakaderera iyo viscosity, iyo yakanyanya solubility ine.Mhando dzakasiyana dzeHPMC dzakasiyana mune zvimwe zvivakwa uye kunyungudika kwavo mumvura hakukanganiswe nepH.
3) Particle saizi: 100% kupasa mwero mu80 mesh.
4) Density inooneka: 0.25-0.70 g/mL (kazhinji inenge 0.5 g/mL), density chaiyo 1.26-1.31mL.
5) Kupisa kwemavara: 190-200 ° C;Carbonization tembiricha: 280-300°C.
6) Kushungurudzika kwepamusoro: 42-56 dyn / cm (2% aqueous solution).
7) Iyo yepamusoro methoxy yemukati muHPMC, yakadzika gelation tembiricha, uye yakanyanya solubility mumvura uye pamusoro pekuita.
8) HPMC ine humwe humwe hunhu, semuenzaniso, kukora chivakwa, pH kugadzikana, kuchengetwa kwemvura, yakanakisa firimu-yekugadzira pfuma, yakanaka kuparadzira uye kugona kunamatira.
