Kuvaka giredhi MHEC

Kuvaka giredhi MHEC Methyl HydroxyethylCelluloseipfumbu chena isinganhuhwi, isina muchetura inogona kunyungudutswa mumvura inotonhora kuti iite sparent viscous solution. Iyo ine hunhu hwekukora, kubatana, kupararira, emulsification, kuumbwa kwemafirimu, kumiswa, adsorption, gelation, chiitiko chepamusoro, kuchengetedza mwando uye inodzivirira colloid. Sezvo iyo aqueous mhinduro ine pamusoro inoshanda basa, inogona kushandiswa se colloidal inodzivirira agent, emulsifier uye dispersant. Kuvaka giredhi MHEC methyl Hydroxyethylcellulose aqueous solution ine yakanaka hydrophilicity uye inoshanda inochengetedza mvura. Hydroxyethyl methyl cellulose ine hydroxyethyl mapoka, saka ine yakanaka anti-mold kugona, yakanaka viscosity kugadzikana uye anti-mildew panguva yekuchengetedza kwenguva refu.

Zvenyama nemakemikari zvivakwa:

Kuonekwa: MHEC yakachena kana inenge yakachena fibrous kana granular powder; isina hwema.

Solubility: MHEC inogona kunyungudika mumvura inotonhora uye inopisa mvura, L modhi inogona kungonyungudika mumvura inotonhora, MHEC haina kunyungudika mune yakawanda organic solvents. Mushure mekurapwa kwepamusoro, MHEC inopararira mumvura inotonhora isina kusanganiswa, uye inonyungudika zvishoma nezvishoma, asi inogona kukurumidza kunyungudika nekugadzirisa iyo PH kukosha kwayo kwe8 ~ 10.

PH kugadzikana: Iyo viscosity inoshandura zvishoma mukati meiyo 2 ~ 12, uye viscosity inoderera kupfuura iyi chiyero.

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

Inooneka density: 0.30-0.60g/cm3.

Application 

Kuvaka giredhi MHEC methyl Hydroxyethyl cellulose inogona kushandiswa seyekudzivirira colloid, emulsifier uye dispersant nekuda kweiyo yepamusoro inoshanda basa mune yayo aqueous solution. Mienzaniso yemashandisirwo ayo ndeiyi inotevera:

1. Mhedzisiro ye methylhydroxyethylcellulose pane simenti performance.Building giredhi MHEC methylHydroxyethylcellulose is an odorless, tasteless, non-chepfu chena poda inogona kunyungudutswa mumvura inotonhora kuti iite transparent viscous solution. Iyo ine hunhu hwekukora, kubatana, kupararira, emulsification, kuumbwa kwemafirimu, kumiswa, adsorption, gelation, chiitiko chepamusoro, kuchengetedza mwando uye inodzivirira colloid. Sezvo mushonga wemvura une pamusoro unoshanda basa, inogona kushandiswa sechidziviriro colloid, emulsifier uye dispersant.Building giredhi MHEC methyl Hydroxyethyl cellulose aqueous solution ine yakanaka hydrophilicity uye inonyatsoshanda kuchengetedza mvura.
2. Gadzirira pende yekuyamura nepamusoro-soro, iyo inogadzirwa nezvikamu zvinotevera nekurema kwezvinhu zvakasvibirira: 150-200g yemvura yakasvibiswa; 60-70g ye pure acrylic emulsion; 550-650g ye calcium inorema; 70-90 g yeti; 30-40g yemethyl cellulose aqueous solution; 10-20g ye lignocellulose aqueous solution; 4-6g yezvibatsiro zvekugadzira firimu; 1.5-2.5g yeantiseptic fungicide; 1.8-2.2g ye dispersant; 1.8-2.2g ye wetting agent; Thickener 3.5-4.5g; ethylene glycol 9-11g; iyo Kuvaka giredhi MHEC aqueous solution inogadzirwa ne2-4% Kuvaka giredhi MHEC yakanyungudika mumvura; thecellulose fiberAqueous solution inogadzirwa ne1 -3%cellulose fiberinogadzirwa nekunyungudika mumvura.

Kugadzira seiKuvaka giredhi MHEC?

Theproductionnzira yeKuvaka giredhi MHEC methyl hydroxyethyl cellulose ndeyokuti donje rakanatswa rinoshandiswa seyakagadzirwa uye ethylene oxide inoshandiswa se etherifying agent kugadzirira Kuvaka giredhi MHEC. Zvigadzirwa zvekugadzirira Kuvaka giredhi MHEC zvakagadzirirwa muzvikamu nekurema: 700-800 zvikamu zve toluene uye isopropanol musanganiswa se solvent, 30-40 zvikamu zvemvura, 70-80 zvikamu zve sodium hydroxide, 80-85 zvikamu zvedonje rakanatswa, mhete 20-28 zvikamu zve oxyethane, 80-90 zvikamu zvemethyl chloride, 16-19 zvikamu zveglacial acetic acid; matanho chaiwo ndeaya anotevera:

Muchikamu chekutanga, wedzera musanganiswa we toluene uye isopropanol, mvura, uye sodium hydroxide mu kettle inopindura, simudza kutonhora kusvika 60-80 ° C, uye uchengetedze kwemaminitsi makumi maviri-40;

Danho rechipiri, alkalization: tonhodza zvinhu zviri pamusoro kusvika 30-50 ° C, wedzera donje rakanatswa, pfapfaidza nemusanganiswa wetoluene uye isopropanol, buda kuenda ku0.006Mpa, zadza nenitrogen kune 3 zvinotsiva, uye ita alkali mushure mekutsiva The alkalization mamiriro. ndeaya anotevera: alkalization nguva i2 maawa, uye alkalization tembiricha i30 ℃-50 ℃;

Nhanho yechitatu, etherification: mushure me alkalization, reactor inobviswa kusvika 0.05～0.07MPa, ethylene oxide uye methyl chloride inowedzerwa uye inochengeterwa makumi matatu.～50 maminitsi; nhanho yekutanga ye etherification: 40～60 ℃, 1.0～2.0 Maawa, kudzvanywa kunodzorwa pakati pe0-0.3Mpa; chikamu chechipiri che etherification: 60～90 ℃, 2.0～Maawa 2.5, kudzvanywa kunodzorwa pakati pe0.4-0.8Mpa;

Danho rechina, neutralization: wedzera metered glacial acetic acid in advance kune desolventizer, dzvanya mune etherified material ye neutralization, wedzera tembiricha kusvika 75.～80 ℃ ye desolventization, tembiricha ichakwira kusvika 102 ℃, uye pH kukosha ichava 68. Kana dongo rapera; zadza kettle yekuparadza nemvura yepombi inobatwa nereverse osmosis mudziyo pa90 ℃.～100 ℃;

Nhanho yechishanu, centrifugal washing: zvinhu zviri muchikamu chechina zvakasvibiswa nehorizontal screw centrifuge, uye zvinhu zvakaparadzana zvinotamirwa kune kettle yekugeza yakazadzwa nemvura inopisa mberi kwekugezwa kwezvinhu;

Nhanho yechitanhatu, kuomeswa kwecentrifugal: zvinhu zvakashambidzwa zvinotakurwa muomesi kuburikidza nehorizontal screw centrifuge, zvinhu zvakaomeswa pa 150-170 ° C, uye zvinhu zvakaomeswa zvinopwanyika uye zvakaputirwa.

Kuenzaniswa neiyo iripo cellulose ether kugadzira tekinoroji, yazvinokugadzira nzirainoshandisa ethylene oxide seye etherifying agent kugadzirira Kuvaka giredhi MHEC methyl hydroxyethyl cellulose, uye nekuti ine hydroxyethyl mapoka, ine yakanaka antifungal kugona. Yakanaka viscosity kugadzikana uye mildew kuramba panguva yekuchengetedza kwenguva refu. Inogona kutsiva mamwe cellulose ethers.

Bkugadzira giredhi MHECinonzi cellulose ether derivatives,Cellulose ether ipolymer yakanaka makemikari zvinhu zvine huwandu hwakasiyana hwekushandisa hwakagadzirwa kubva kune zvakasikwa polymer cellulose kuburikidza nemakemikari kurapwa. Sezvo cellulose nitrate uye cellulose acetate zvakaitwa muzana remakore rechi19, chemist vakagadzira akawanda akatevedzana e cellulose anobva kune cellulose ethers. Minda mitsva yekunyorera inogara ichiwanikwa uye mazhinji maindasitiri zvikamu zvinobatanidzwa. Cellulose ether zvigadzirwa zvakadai sodium carboxymethyl cellulose (CMC), ethyl cellulose (EC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), methyl hydroxyethyl cellulose (MHEC) Uye methyl hydroxypropyl cellulose (MHPC) uye mamwe cellulose ethers anozivikanwa se. "industrial monosodium glutamate" uye yekuvaka giredhi MHEC yakashandiswa zvakanyanya mukunamira mataira, yakaoma dhaka, simende uye gypsum plasters nezvimwe.
