FAQS
HPMC kanaHydroxypropyl methylcellulose(INN zita: Hypromellose), zvakare rakarerutswa sehydroxypropyl methylcellulose (HPMC), imhando yeisina-ionic cellulose yakasanganiswa ether. Iyo semi-synthetic, isingashande, viscoelastic polymer. Hydroxypropyl methylcellulose inoshandiswa zvakanyanya mukuvaka, chikafu, mushonga, uye mamwe maindasitiri.
HPMC CAS Nhamba: 9004-65-3
HPMC Structural:
HPMC HS CODE: 3912390000
Chemical property:
Kuonekwa: Ichena kana yakafanana nehupfu chena.
Particle size; 100 mesh pass rate inopfuura 98.5%; 80 mesh pass rate i100%. Particle saizi yezvakakosha zvakatemwa kubva pa40 kusvika 60 mesh.
Visual density: 0.25-0.70g/cm (kazhinji inenge 0.5g/cm), yakananga giravhiti 1.26-1.31.
Solubility: Soluble mumvura uye zvimwe zvinonyungudutsa, zvakadai sechikamu chakakodzera ethanol / mvura, propanol / mvura, etc. Mushonga wemvura une basa repamusoro. Nekujeka kwepamusoro uye kushanda kwakagadzikana, tembiricha yegel yezvakasiyana zvakasiyana, solubility inoshanduka ne viscosity, viscosity yakaderera uye solubility yakakura. Kuita kweHPMC neakasiyana mataurirwo ane mutsauko. Kuparara kweHPMC mumvura hakukanganisike nePH kukosha.
HPMC yakagadzirwa naLongou:
Longou iri kugadzira nekupa marudzi akasiyana eHPMC neHEMC(MODCELL®) ekushandisa kwakasiyana. Kazhinji, Longou HPMC ine maviri akateedzana HPMC, imwe nhevedzano yeHEMC uye yakagadziridzwa zvigadzirwa.

Hydroxypropyl methylcellulose (HPMC) macellulose ether anga aine mapoka ehydroxyl pacheni ye cellulose akatsiva methoxy kana hydroxypropyl boka.It inogadzirwa neakakosha etherification yeyakanyanya yakachena donje cellulose pasi pemamiriro ealkaline. Mumakore achangopfuura, HPMC, senge inoshanda musanganiswa, inonyanya kuita basasmukuchengetedza mvura uye kukora muindasitiri yekuvaka uye inoshandiswa zvakanyanya mukatidrymix matope, senge mataira anonamira, grouts, plastering, wall putty, self leveling, insulation dhaka uye nezvimwe.
Kazhinji, yeputty powder, iyo viscosity yeHPMCinokwana pa70,000 kusvika ku80,000. Chinonyanya kutariswa ndechekuita kwayo kwekuchengetedza mvura, nepo kukora mhedzisiro kuri kudiki. Zvedhaka, zvinodiwa zveHPMCdzakakwirira, uye viscosity inoda kutenderedza 150,000, iyo inogona kuve nechokwadi kuti inoshanda zvirinani mudhaka resimende. Zvechokwadi, muputty powder, chero bedzi kushandiswa kwekuchengetedza mvura kweHPMC kwakanaka, kunyange kana viscosity yakaderera (70,000 kusvika 80,000), inogamuchirwa. Zvisinei, mudhaka resimende, inonyanya kunaka kusarudza HPMC ine viscosity yakakura (inopfuura 100,000), nokuti iyo yekuchengetedza mvura inokonzera inonyanya kukosha mumamiriro ezvinhu aya.
Dambudziko rekubvisa putty powder rinonyanya kuenderana nemhando ye calcium hydroxide uye haina zvishoma zvekuita neHPMC. Kana iyo calcium ye calcium hydroxide yakaderera kana chiyero cheCaO uye Ca (OH) 2 isina kukodzera, inogona kuita kuti putty powder iwa. Nezvekukanganisa kweHPMC, inonyanya kuratidzwa mukuita kwayo kwekuchengetedza mvura. Kana iyo HPMC yekuchengetedza mvura ichiita isina kunaka, inogona zvakare kuve nemhedzisiro pakupera kweputty powder.
Zvinodiwa zvekushandiswa kweputty powder zvakaderera. A viscosity ye100,000 yakakwana. Chinokosha ndechekuva nemaitiro akanaka ekuchengetedza mvura. Panyaya yedhaka, izvo zvinodikanwa zvakakwirira uye yakakwirira viscosity inodiwa, uye iyo 150,000 chigadzirwa chine mhedzisiro iri nani.
(1) Indasitiri yekuvaka: Sechinhu chinochengeta mvura uye chinodzoreredza simende dhaka, inoita kuti dhaka ripombike. Shandisa plaster, gypsum, putty poda kana zvimwe zvinhu zvekuvaka seanonamira kuti uvandudze kushanda uye kurebesa nguva yekushanda. Inogona kushandiswa kunama mataira eceramic, marble, kushongedzwa kwepurasitiki, namira inosimbisa mumiriri, uye kuderedza huwandu hwesimende. Iyo mvura-yekuchengetedza pfuma yeHPMC inodzivirira slurry kubva pakutsemuka nekuda kwekuoma nekukurumidza mushure mekuzora uye kuwedzera simba.
(2) Ceramic kugadzira indasitiri: inoshandiswa zvakanyanya seanonamira mukugadzira zvigadzirwa zveceramic.h mushure mekuoma.
(3) Indasitiri yekuputira: Seyakakora, dispersant uye stabilizer muindasitiri yekupfeka, ine yakanaka solubility mumvura kana organic solvents.
(4) Ingi inodhinda: Seyakakora, dispersant uye stabilizer muindasitiri yeinki, ine yakanaka solubility mumvura kana organic zvinonyungudutsa.
(5) Plastics: sekugadzira kuburitsa mumiriri, softener, lubricant, nezvimwe.
(6) Polyvinyl chloride: Sezvinoparadzira mukugadzirwa kwepolyvinyl chloride, ndiyo mubatsiri mukuru mukugadzirira kwePVC nekumisa polymerization.
(7) Zvimwe: Ichi chigadzirwa chinoshandiswa zvakanyanya mumatehwe, zvigadzirwa zvemapepa, kuchengetedza michero nemiriwo, uye indasitiri yemachira.
