Giredhi rekuvaka MHEC

Chivako cheMHEC Methyl HydroxyethylCelliloseihupfu huchena husina hwema, husina kunaka, husina chepfu hunogona kunyungudutswa mumvura inotonhora kuti hugadzire mhinduro inopenya yakajeka. Hune hunhu hwekukora, kubatana, kupararira, emulsification, kuumbwa kwefirimu, kumisa, kunyungudutsa, gelation, kushanda kwepamusoro, kuchengetedza hunyoro uye colloid inodzivirira. Sezvo mhinduro yemvura iine basa rekushanda pamusoro, inogona kushandiswa semushonga unodzivirira colloidal, emulsifier uye dispersant. Mushonga wekuvaka wemhando yeMHEC methyl Hydroxyethylcellulose aqueous une hydrophilicity yakanaka uye mushonga unoshanda wekuchengetedza mvura. Hydroxyethyl methyl cellulose ine hydroxyethyl groups, saka ine kugona kwakanaka kwekudzivirira mold, kugadzikana kwakanaka kwe viscosity uye anti-mildew panguva yekuchengetwa kwenguva refu.

Hunhu hwemuviri uye hwemakemikari:

Chitarisiko: MHEC ipfu chena kana kuti inenge chena ine fibrous kana granular; haina hwema.

Kunyungudika: MHEC inogona kunyungudika mumvura inotonhora nemvura inopisa, L model inogona kunyungudika mumvura inotonhora chete, MHEC hainyungudike mune zvakawanda zvinonyungudika zve organic. Mushure mekugadzirisa pamusoro, MHEC inopararira mumvura inotonhora isina kuungana, uye inonyungudika zvishoma nezvishoma, asi inogona kunyungudika nekukurumidza nekugadzirisa PH yayo ye8~10.

Kugadzikana kwePH: Kuyerera kwemvura hakuchinji zvakanyanya mukati me2 ~ 12, uye kuyerera kwemvura kunoderera kupfuura huwandu uhu.

Kuwanda: 40 mesh pass rate ≥99% 80 mesh pass rate 100%.

Kuwanda kwechinhu kunoratidzika: 0.30-0.60g/cm3.

Kushandiswa 

Mushonga wekuvaka weMHEC methyl Hydroxyethyl cellulose unogona kushandiswa se colloid inodzivirira, emulsifier uye dispersant nekuda kwebasa rayo pamusoro pemvura. Mienzaniso yekushandiswa kwayo ndeiyi inotevera:

1. Mhedzisiro yemethylhydroxyethylcellulose pakushanda kwesimende. Mushonga wekuvaka MHEC methylHydroxyethylcellulose upfu huchena husina hwema, husina kunaka, husina chepfu hunogona kunyungudutswa mumvura inotonhora kuti hugadzire mhinduro yakajeka ine viscous. Hune hunhu hwekukora, kubatana, kupararira, emulsification, kuumbwa kwefirimu, kumisa, adsorption, gelation, surface activity, hunyoro hwekuchengetedza uye colloid inodzivirira. Sezvo mhinduro yemvura iine basa rekushanda pamusoro, inogona kushandiswa se colloid inodzivirira, emulsifier uye dispersant. Mushonga wekuvaka MHEC methyl Hydroxyethyl cellulose aqueous solution ine hydrophilicity yakanaka uye inoshanda kuchengetedza mvura.
2. Gadzirira pendi yekubvisa tsvina ine kuchinjika kwakanyanya, inogadzirwa nezvikamu zvinotevera zvichienderana nehuremu hwezvinhu zvakagadziriswa: 150-200g yemvura yakabviswa ion; 60-70g ye emulsion yakachena ye acrylic; 550-650g ye calcium yakawanda; 70-90g ye talc; 30-40g ye methyl cellulose aqueous solution; 10-20g ye lignocellulose aqueous solution; 4-6g ye aids yekugadzira mafirimu; 1.5-2.5g ye antiseptic fungicide; 1.8-2.2g ye dispersant; 1.8-2.2g ye wetting agent; Thickener 3.5-4.5g; ethylene glycol 9-11g; mhinduro yemvura ye Building grade MHEC inogadzirwa ne 2-4% Building grade MHEC yakanyungudutswa mumvura;faibha ye cellulosemvura inogadzirwa ne1 -3%faibha ye celluloseinogadzirwa nekunyungudika mumvura.

Maitiro ekugadziraChivako cheMHEC？

IyokugadzirwaNzira yekuvaka MHEC grade methyl hydroxyethyl cellulose ndeyekuti donje rakanatswa rinoshandiswa sechinhu chisina kugadzirwa uye ethylene oxide inoshandiswa sechinhu chinosimbisa muviri kugadzira MHEC yemhando yekuvaka. Zvinhu zvisina kugadzirwa zvekugadzira MHEC yemhando yekuvaka zvinogadzirwa muzvikamu nehukuru: zvikamu 700-800 zvemusanganiswa wetoluene neisopropanol se solvent, zvikamu 30-40 zvemvura, zvikamu 70-80 zve sodium hydroxide, zvikamu 80-85 zvedonje rakanatswa, ring zvikamu 20-28 zve oxythane, zvikamu 80-90 zve methyl chloride, zvikamu 16-19 zve glacial acetic acid; matanho chaiwo ndeaya anotevera:

Mudanho rekutanga, wedzera musanganiswa we toluene ne isopropanol, mvura, uye sodium hydroxide mukettle ye reaction, wedzera tembiricha kusvika 60-80°C, woichengeta kwemaminitsi 20-40;

Danho rechipiri, alkalization: tonhodza zvinhu zvataurwa pamusoro apa kusvika pa30-50°C, wedzera donje rakanatswa, pfapfaidza nemusanganiswa wetoluene neisopropanol, bvisai kusvika pa0.006Mpa, zadzai nenitrogen kuti mutsive katatu, uye gadzirai alkalis mushure mekutsiva. Mamiriro ealkalization ndeaya anotevera: nguva yealkalization maawa maviri, uye tembiricha yealkalization i30℃-50℃;

Danho rechitatu, etherification: mushure mekugadziriswa kwealkali, reactor inobviswa kuenda ku0.05～0.07MPa, ethylene oxide uye methyl chloride zvinowedzerwa uye zvinochengetwa kwe30～Maminetsi makumi mashanu; danho rekutanga re etherification: 40～60℃, 1.0～Maawa 2.0, kumanikidzwa kunodzorwa pakati pe0.15-0.3Mpa; danho rechipiri re etherification: 60～90℃, 2.0～Maawa maviri nehafu, kumanikidzwa kunodzorwa pakati pe0.4-0.8Mpa;

Danho rechina, kusabvisa ganda: wedzera glacial acetic acid yakayerwa pachine nguva kumuchina wekubvisa ganda, dzvanya muzvinhu zvine ether kuti usabvisa ganda, wedzera tembiricha kusvika pa75～80℃ yekubvisa tsvina, tembiricha ichakwira kusvika 102℃, uye pH ichava 68. Kana tsvina yapera; zadza ketero yekudzima tsvina nemvura yepombi yakanatswa ne reverse osmosis device pa90℃.～100℃;

Danho rechishanu, kugeza uchishandisa centrifugal: zvinhu zviri mudanho rechina zvinoiswa centrifuge ne centrifuge yakatambanudzwa, uye zvinhu zvakaparadzaniswa zvinoiswa muketero yekugeza yakazadzwa nemvura inopisa pachine nguva kuti zvinhu zvisukwe;

Danho rechitanhatu, kuomesa uchishandisa centrifugal: zvinhu zvakagezwa zvinotakurwa zvichiiswa mudryer kuburikidza ne centrifuge yakatambanudzwa, zvinhu zvinoomeswa pa 150-170°C, uye zvinhu zvakaomeswa zvinopwanywa uye zvinorongedzwa.

Zvichienzaniswa netekinoroji yekugadzirwa kwe cellulose ether iripo, iriponzira yekugadzirainoshandisa ethylene oxide semushonga wekupisa kugadzirira MHEC methyl hydroxyethyl cellulose yeBuilding grade, uye nekuti ine mapoka ehydroxyethyl, ine kugona kwakanaka kwekuuraya fungus. Kugadzikana kwakanaka kweviscosity uye kuramba kwefungus panguva yekuchengetwa kwenguva refu. Inogona kutsiva mamwe ma cellulose ethers.

BMHEC yemhando yepamusorozvinogadzirwa ne cellulose ether,Cellulose ether ipurasitiki yakagadzirwa nepolymer ine mashandisirwo akasiyana-siyana akagadzirwa kubva kupolymer cellulose yechisikigo kuburikidza nekurapa nemakemikari. Sezvo cellulose nitrate ne cellulose acetate zvakagadzirwa muzana remakore rechi19, makhemisi akagadzira akawanda ma derivatives e cellulose ethers. Nzvimbo itsva dzekushandisa dziri kuwanikwa nguva dzose uye maindasitiri mazhinji anobatanidzwa. Zvigadzirwa zveCellulose ether zvakaita se sodium carboxymethyl cellulose (CMC), ethyl cellulose (EC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), methyl hydroxyethyl cellulose (MHEC) Uye methyl hydroxypropyl cellulose (MHPC) nedzimwe cellulose ethers dzinozivikanwa se "industrial monosodium glutamate" uye building grade MHEC dzakashandiswa zvakanyanya mu tile adhesive, dry mortar, simende uye gypsum plasters nezvimwewo.
