Ukwakha Ibanga Mhec

Ibanga lokwakha Mhec

Ukwakha Ibanga Mhec Methyl hydroxyethylCElluloseiyimpuphu ye-odorless, engenambitha, engeyona into enobuthi emhlophe engachithwa emanzini abandayo ukwakha ikhambi elibonakalayo le-viscous. Inezici zokuqina, ukubopha, ukuhlakazeka, ukuhlukaniswa, ukwakheka kwamafilimu, ukumiswa, ukumiswa kwe-adsorption, ukugcinwa komhlaba, ukugcinwa komswakama nokuvikela i-colloid ne-colloid yomswakama kanye nokuvikela i-colloid. Njengoba ikhambi elinamanzi linomsebenzi osebenzayo ongaphezulu, lingasetshenziswa njenge-ejenti yokuvikela i-colloidal, emulsifier kanye ne-dispersant. Ibanga le-Cardn Mhec Methyl Hydroxyylcelcelcelcelcelcevulose line-hydrophility enhle futhi i-ejenti yokugcina amanzi esebenza kahle. I-Hydroxyyethyl methyl celtulese iqukethe amaqembu ama-hydroxyethyl, ngakho-ke inekhono elihle lokulwa nokulwa, ukuqina okuhle nokuqina kanye nokulwa ne-anti-isikhutha ngesikhathi sokugcina isikhathi eside.

Izakhiwo ezingokomzimba nezamakhemikhali:

Ukubukeka: I-MHEC imhlophe noma icishe ibe mhlophe noma i-powder emhlophe; ngaphandle kwe-odorless.

I-Solubinity: I-Mhec ingancibilika emanzini abandayo namanzi ashisayo, imodeli ye-L ingancibilika kuphela emanzini abandayo, i-MHEC ingenakufakelwa inqwaba ye-organic solvents. Ngemuva kokwelashwa komhlaba, iMhec isabalalisa emanzini abandayo ngaphandle kwe-agglomeration ngaphandle kwe-agglomeration, futhi inciphise kancane, kepha ingancibilika ngokushesha ngokulungisa inani layo le-PH le-8 ~ 10.

Ukuqina kwe-PH: I-Viscosity ishintsha okuncane ngaphakathi kwebanga le-2 ~ 12, futhi ukubonwa kwento kuncipha ngaphezu kwalolu banga.

Granularity: 40 Mesh Pass Rate ≥99% 80 Mesh Pass Rate 100%.

Ukubukeka okubonakalayo: 0.30-0.60g / cm3.

Isicelo 

Ibanga le-Cardn Mhec Methyl hydroxyyl celtule Izibonelo zokusetshenziswa kwazo zimi ngokulandelayo:

1. Umphumela we-methylhydroxyethylellose ekusebenzeni kosekhukhweni. Inezici zokuqina, ukubopha, ukuhlakazeka, ukuhlukaniswa, ukwakheka kwamafilimu, ukumiswa, ukumiswa kwe-adsorption, ukugcinwa komhlaba, ukugcinwa komswakama nokuvikela i-colloid ne-colloid yomswakama kanye nokuvikela i-colloid. Njengoba ikhambi elinamanzi linomsebenzi osebenzayo ongaphezulu, lingasetshenziswa njenge-colloid evikelayo, i-emulsifier kanye ne-dispsant.Bunging grade Mhec methyl hydrophility lyropilityyl pultuleose i-hydrophility i-hydrophility enhle.
2. Lungiselela upende wokusiza ngokuguquguquka okuphezulu, okwenziwe ngezingxenye ezilandelayo ngesisindo sezinto zokwakha: 150-200g wamanzi abonakalayo; 60-70g we-acrylic emsulwa; I-550-650g ye-calcium esindayo; I-70-90g yeTalc; 30-40g we-methyl cellulose ikhambi elinamanzi; I-10-20g yeLignocellulose ikhambi elinamanzi; I-4-6g yengculazi eyakha amafilimu; 1.5-2.5g we-fungicide ye-antiseptic; 1.8-2.2g of Depsant; 1.8-2.2g we-ejenti emanzi; Mkhulu 3.5-4.5g; ethylene glycol 9-11g; Isixazululo seBandla Lakha i-MHEC senziwe nge-2-4% Ibanga le-Mhec lincibilike emanzini; le khasiI-cellulose fiberIsixazululo esinamanzi senziwa nge-1 -3%I-cellulose fiberyenziwa ngokuncibilika emanzini.

Ungayikhiqiza kanjaniUkwakha Ibanga Mhec?

Le khasiumkhiqizoIndlela yokwakha iBanga le-Mhec Methyl hydroxyyl celtulose lelo thoto elicwengekile lisetshenziswa njengezinto ezisetshenziswayo ne-ethylene oxide zisetshenziswa njenge-ejenti etherali ukulungiselela ukwakha i-ejenti yokwakha iBandla le-Mhec. Izinto ezivuthiwe zokulungiselela ukwakheka kweBanga le-Mhec zilungiselelwe izingxenye ngesisindo: izingxenye ezingama-700-800 ze-toluene ne-sopropanol njenge-solvent, izingxenye ezingama-30-8-80 ze-sodium hydroxide, Ring 20-28 izingxenye ze-Oxyethane, izingxenye ezingama-80-90 ze-methyl chloride, izingxenye eziyi-16-19 ze-glacial acetic acid; Izinyathelo ezithile zinjengokulandelayo:

Esinyathelweni sokuqala, engeza ingxube ye-toluene ne-isopropanol, amanzi, ne-sodium hydroxide ku-kettle yokuphendula, khulisa amazinga okushisa kuya ku-60-80 ° C, futhi uyigcine imizuzu engama-20 ukuya kwengama-40;

Isinyathelo sesibili, i-alkalization: pholisa izinto ezingenhla ku-30-50 ° C, engeza ukotini ocwengekile, ufafaza nge-nitrogen, bese wenza i-alkalis ngemuva kwezimo ze-alkalization kungokulandelayo: isikhathi se-alkaliation ngamahora ama-2, futhi izinga lokushisa le-alkalization lingu-30 ℃-50 ℃;

Isinyathelo sesithathu, ukusheshisa: ngemuva kokuzalwa kwe-alkali, i-reactor ikhishwe ku-0.05~I-0.07MPA, i-ethylene oxide ne-methyl chloride yengezwa futhi igcinwe iminyaka engama-30~Imizuzu engama-50; isigaba sokuqala sokuthezeka: 40~60 ℃, 1.0~Amahora angama-2.0, ingcindezi ilawulwa phakathi kuka-0.15-I-0.3MPA; isigaba sesibili sokuthezeka: 60~90 ℃, 2.0~Amahora angama-2,5, ingcindezi ilawulwa phakathi kuka-0.4-I-0.8MPA;

Isinyathelo sesine, ukungathathi hlangothi: Faka i-metered acetic acetic acid acid kusengaphambili ku-decolventizer, cindezela imininingwane ethe xaxa yokungathathi hlangothi, ukukhulisa izinga lokushisa libe ngu-75~I-80 ℃ ye-desolventization, izinga lokushisa lizokhuphuka libe ngu-102 ℃, futhi inani le-PH lizoba ngama-68. Lapho indlala iphothuliwe; Gcwalisa i-kettle ye-dese nge-tap water ephathwa yidivaysi yokubuyisela emuva kwe-Osmosis ku-90 ℃~100 ℃;

Isinyathelo sesihlanu, ukugeza izingxenye: izinto zokwakha esigabeni sesine zisenqatshelwe yisikulufu esivundlile se-centrifuge, kanti nezinto zokwehlukaniswa zidluliselwa echibini lokugeza eligcwele amanzi ashisayo;

Isinyathelo sesithupha, ukomisa okwenziwe ngesenti: Izinto ezihlanjiwe zihanjiswa esomile ngesikulufu esivundlile se-centrifuge centrifuge, izinto zokwakha zomiswa ngo-150-170 ° C, nezinto zomisiwe zichobozekile futhi zihlanganiswa.

Qhathanisa nobuchwepheshe obukhona be-cellulose ether ether, okwamanjeIndlela yokukhiqizaIsebenzisa i-Ethylene oxide njenge-ejenti yokuphelisa ukulungiselela ukwakha iBanga le-methyl hydroxyethyl cellulose, futhi ngoba liqukethe amaqembu ama-hydroxyethyl, linekhono elihle le-antifungal. Ukuzikhethela okuhle nokuphikiswa kombangela ngesikhathi sokugcina isikhathi eside. Ingangena esikhundleni sezinye izithambiso ze-cellulose.

BIbanga le-Uilding grade MhecIngabe i-cellulose ether derivatives,I-Cellulose Ether iyinto eyenziwe ngamakhemikhali amahle we-polymer anhlobonhlobo yokusetshenziswa okwenziwe kusuka ku-polymer cellulose yemvelo ngokwelashwa kwamakhemikhali. Kusukela ku-Cellulose Nitrate kanye ne-cellulose acetate kwenziwa ngekhulu le-19, osokhemisi bathuthukise ama-cellulose decivatives of cellulose asher. Izinkambu ezintsha zohlelo lokusebenza zitholakala njalo futhi imikhakha eminingi yezimboni iyabandakanyeka. Imikhiqizo ye-cellulose ether efana ne-sodium carboxyyllllls (CMC), i-ethyl cellulose (EC), i-hpdroxypropyl cellulose (HPPC) kanye ne-methyl hydroxyyllosel (HPPC) kanye nezinye izimpi ze-cellulose zaziwa ngokuthi "I-monosodium yezimboni i-glutamate" nokwakha iBanga le-Mhec lisetshenziswe kabanzi ku-tile anamathela, udaka owomile, usimende kanye ne-gypsum plasters njll.
