Hydroxypropyl Methylcellulose HPMC
Muzvivakwa zvekuvaka, inoshandiswa sechinhu chekuchengetedza mvura uye retarder yesamende sludge ine pumpability.Inogona kushandiswa sebhainda mupurasita, gypsum, inverted poda kana zvimwe zvekuvaka kuvandudza kupararira uye kurebesa nguva yekushanda.Inogona kushandiswa sechishandiso chekunamira zvidhinha, mataira, marbles, mapurasitiki ekushongedza, uye ma bonding intensifiers.Inogonawo kuderedza kuwanda kwesamende.Kuchengetwa kwemvura kweHPMCinodzivirira slurry kubva pakutsemuka nekuda kwekuoma nekukurumidza mushure mekupfeka, uye inowedzera simba mushure mekuoma.
Pamusoro pezvo, inoshandiswa seyakakora, kugadzikana, emulsifier, excipient, kuchengetedza mvura mukugadzira mamwe petrochemicals, machira, zvekuvakisa, zvekubvisa pendi, makemikari ekurima, ingi, kudhinda machira uye dhayi, ceramics, papermaking, uye cosmetic brands.Mumiririri, mumiriri wekugadzira firimu, nezvimwe.
1. Chitarisiko: chichena kana chinenge chichena chepfu, chisina kunhuwa uye chisina kunaka.
2. Granularity: 10 mesh pass rate yakakura kudarika 98.5%;80 mesh pass rate yakakura kupfuura 100%.
3. Carbonization tembiricha: 280-300 ℃.
4. Room density: 0.25-0.7G / CM3 (kazhinji inenge 0.5G / CM3), iyo chaiyo giravhiti ndeye 1.26-1.31.
5. Discoloration tembiricha: 190-200 ℃.
6. Kupisa kwepanyama: inenge 360 ℃.
Kugadzira Nzira
Iyo yakanatswa yekotoni cellulose inobatwa nelye pa 35-40 ° C kwehafu yeawa, yakasvinwa, iyo cellulose inopwanyika, uye yakanyatso kuchembera pa 35 ° C, kuitira kuti yakawanikwa alkali fiber avhareji dhigirii yepolymerization iri mukati meiyo inodiwa.Isa iyo alkali faibha muketero etherification, wedzera propylene oxide uye methyl chloride zvakatevedzana, uye etherify pa50-80 ℃ kwe5h, iyo yakanyanya kudzvanywa inenge 1.8MPa.Wobva wawedzera huwandu hwakakodzera hwehydrochloric acid uye oxalic acid kushambidza zvinhu mumvura inopisa pa90 ° C kuti uwedzere huwandu.Dehydrate ne centrifuge.Geza kuti usarerekera.Kana mvura iri muzvinhu iri pasi pe60%, iomese nerukova rwemhepo inopisa pa130 ℃ kusvika pasi pe5%.Pakupedzisira, inopwanyika kuburikidza nesefa ye20-mesh kuti iwane chigadzirwa chakapedzwa.
