Lub Tsev Qeb MeEC

Tsev qib MHEC MEthyl HydroxyethylCtso tsegyog tus ntxhiab tsw ntxhiab, cov tsis tau muaj txiaj ntsig, cov hmoov dawb dawb uas tuaj yeem yaj hauv dej txias kom tsim cov tshuaj pleev pob tshab. Nws muaj cov yam ntxwv ntawm thickening, kev sib cais, emulsification, zaj duab xis, kev ua si, noo noo khaws thiab tiv thaiv kev tiv thaiv thiab tiv thaiv kev tiv thaiv. Vim tias cov kua aqueous muaj cov haujlwm ua haujlwm saum toj ua haujlwm, nws tuaj yeem siv los ua tus neeg sawv cev sib xyaw, emulsifier thiab dispersant. Tsev qib MHEC metyl hydrotylcellment aqueous kua txiv muaj cov dej hydrophilicity zoo thiab yog cov dej ua haujlwm zoo. Hydroxyethyl methyl cellulose muaj cov pab pawg hydroxyethyl, yog li nws tau muaj lub peev xwm tiv thaiv pwm, zoo nkauj muaj peev xwm, zoo nkauj thaum lub sij hawm ntev cia.

Lub cev thiab tshuaj lom neeg:

Zog: MHEC yog dawb lossis yuav luag dawb fibrous lossis granular hmoov; Odless.

Nws muaj cov yam ntxwv ntawm thickening, kev sib cais, emulsification, zaj duab xis, kev ua si, noo noo khaws thiab tiv thaiv kev tiv thaiv thiab tiv thaiv kev tiv thaiv. Txij li cov kua aqueous muaj cov kev ua haujlwm saum npoo av, nws tuaj yeem siv los ua cov tshuaj tiv thaiv axrous muaj cov dej anyrous onerox thiab yog cov dej ua haujlwm zoo.
2. Npaj ib qho xim nyem uas muaj kev hloov pauv siab, uas yog ua los ntawm cov ntu hauv qab no los ntawm qhov hnyav ntawm cov khoom nyoos: 150-200g ntawm dej deionized; 60-70g ntawm acrylic dawb emulsion; 550-650g ntawm calcium hnyav; 70-90g ntawm Talc; 30-40G ntawm methyl cellulose aqueous kev daws teeb meem; 10-20g ntawm Lignocellulose aqueous kua; 4-6g ntawm zaj duab xis-ua kev pab AIDS; 1.5-2.5g ntawm cov kab mob antiseptic; 1.8-2.2g ntawm dispersant; 1.8-2.2g ntawm watetting tus neeg sawv cev; Thickenter 3.5-4.5g; Ethylene glycol 9-11g; Lub tsev qib MHEC AQUouse kev daws teeb meem yog ua los ntawm 2-4% lub tsev qib MHEC tau yaj hauv dej; tusCellulose FibreCov kua aqueous yog ua los ntawm 1 -3%Cellulose Fibreyog tsim los ntawm dissolving hauv dej.

Yuav ua li cas los uaTsev qib MHEC?

Tuskev tsimTxoj kev ntawm lub tsev qib MHEC metyl hydulose yog tias siv cov paj rwb refined yog siv los ua tus neeg sawv cev ntawm lub tsev MHEC. Cov ntaub ntawv raw rau npaj lub tsev qib MHEC tau npaj hauv qhov hnyav, 700-800 xeem ntawm sodium hydroxide, 80-85 ntawm cov paj rwb refine, Ntiv nplhaib 20-28 feem ntawm oxyethane, 80-90 feem ntawm methyl chloride, 16-19 seem ntawm glacial acetic acid; Cov kauj ruam tshwj xeeb yog raws li hauv qab no:

Nyob rau thawj kauj ruam, ntxiv kev sib xyaw ntawm toluene thiab isopropanol, thiab sodium hydroxide rau 60-80 ° C, thiab khaws cia rau 20-40 feeb;

Qhov thib ob, alkalization: txias cov ntaub ntawv saum toj rau 30-50 ° C, tshem tawm cov nitrogen rau 3 hloov alkalis tau tom qab hloov cov txheej txheem alkalization muaj raws li hauv qab no: Lub sijhawm Alkalization yog 2 teev, thiab Alkalization kub yog 30 ℃-50 ℃;

Qhov thib peb theem peb, ethermalification: Tom qab alkalization, reactor raug tshem tawm mus rau 0.05Tom mu0.07mpa, ethylene oxide thiab methyl chloride tau ntxiv thiab khaws cia rau 30Tom mu50 feeb; Thawj theem ntawm Otherification: 40Tom mu60 ℃, 1.0Tom mu2.0 teev, lub siab yog tswj tau ntawm 0.15-0.3mpa; theem ob ntawm ethermov: 60Tom mu90 ℃, 2.0Tom mu2.5 teev, lub siab yog tswj hwm ntawm 0.4-0.8MPA;

Cov kauj ruam thib plaub, nruab nrab: ntxiv lub ntsuas pa tawm glacial acetic acid ua ntej mus rau lub Eetheriened cov khoom siv, nce qhov ntsuas kub rau 75Tom mu80 ℃ rau qhov kev txiav txim siab, qhov kub yuav nce mus rau 102 ℃, thiab tus nqi PH yuav yog 68. Thaum qhov kev tsim txiaj tiav; Sau cov hwj kais uas daws nrog cov dej kais dej kho los ntawm thim rov qab osmosis ntaus ntawm 90 ℃Tom mu100 ℃;

Lub thib tsib kauj ruam, centrifugal ntxuav: cov ntaub ntawv nyob rau hauv cov kauj ruam plaub yog centrifuged los ntawm cov kab rov tav uas tau hloov nrog cov dej kub ua ntej rau kev ntxuav cov ntaub ntawv;

Lub kauj ruam rau, centrifugal kom qhuav: cov khoom ntxuav tau thauj mus rau hauv lub tshuab ziab khaub ncaws, cov ntaub ntawv qhuav ntawm 150-170 ° C, thiab cov khoom qhuav yog crushed thiab ntim.

Piv nrog cov cellulose uas twb muaj lawm ether ntau lawm tshuab, tam sim noTxuj Ci Ntau LawmSiv cov neeg sawv cev MHEtherifying los npaj pab pawg muaj zog MHEC metyl, nws muaj cov kabmob hydroxyettyl Zoo viscosity stability thiab mildew kuj thaum lub sij hawm ntev cia. Nws tuaj yeem hloov lwm yam kev ua cellulose.

Bkho cov qib MHECyog cellulose ether derivatives,Cellulose ether yog cov khoom siv polymer yog cov siv ntau yam uas muaj los ntawm cov polymer cellulose los ntawm kev kho tshuaj lom neeg. Vim tias cellulose nitrate thiab cellulose acetate tau ua nyob rau hauv lub xyoo pua puv 19, kws kho mob tau tsim ntau cov kev ua haujlwm ntawm cellulose muaj kev hais ua. Cov ntawv thov tshiab tau pom tas li tau pom thiab ntau cov haujlwm muaj kev koom tes. Cellulose ether cov khoom xws li sodium carboxymethyl cellulose (HPC) thiab lwm yam kws kho mob hauv tsev (MHPC) thiab lwm yam neeg hais txog cellulropyl "Industrial monosodium glutamate" thiab tsev tsim muaj dav siv hauv cov nplais nplaum, ua kom qhuav, xis mas thiab gypsum plasters thiab lwm yam.
