Ibanga lokwakha i-MHEC

Ibanga lokwakha I-MHEC

Ibanga lokwakha i-MHEC Mi-ethyl HydroxyethylCi-eluloseiyimpushana emhlophe engenaphunga, engenabungozi, engancibilikisiwe emanzini abandayo ukuze yakhe isixazululo se-viscous esisobala. Inezici zokuqina, ukubopha, ukuhlakazeka, i-emulsification, ukwakheka kwefilimu, ukumiswa, i-adsorption, i-gelation, umsebenzi ongaphezulu, ukugcinwa komswakama kanye ne-colloid evikelayo. Njengoba isixazululo esinamanzi sinomsebenzi osebenzayo ongaphezulu, singasetshenziswa njenge-ejenti yokuvikela ye-colloidal, i-emulsifier ne-dispersant. Isixazululo samanzi se-MHEC se-methyl Hydroxyethylcellulose sine-hydrophilicity enhle futhi siyi-ejenti esebenza kahle yokugcina amanzi. I-Hydroxyethyl methyl cellulose iqukethe amaqembu e-hydroxyethyl, ngakho inekhono elihle lokulwa nesikhunta, ukuqina okuhle kwe-viscosity kanye ne-anti-mildew ngesikhathi sokugcina isikhathi eside.

Izakhiwo zomzimba namakhemikhali:

Ukubukeka: I-MHEC imhlophe noma icishe ibe mhlophe noma i-granular powder; engenaphunga.

I-Solubility: I-MHEC ingancibilika emanzini abandayo namanzi ashisayo, imodeli ye-L ingancibilika emanzini abandayo kuphela, i-MHEC ayincibiliki kuma-solvents amaningi e-organic. Ngemva kokwelashwa okungaphezulu, i-MHEC ihlakaza emanzini abandayo ngaphandle kokuhlanganiswa, futhi incibilika kancane, kodwa ingahlakazwa ngokushesha ngokulungisa inani layo le-PH elingu-8~10.

PH Ukuzinza: I-viscosity ishintsha kancane phakathi kwebanga elingu-2~12, futhi i-viscosity yehla ngale kwalolu bubanzi.

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

Ukuminyana okubonakalayo: 0.30-0.60g/cm3.

Isicelo 

Ibanga lokwakha i-MHEC i-methyl Hydroxyethyl cellulose ingasetshenziswa njenge-colloid evikelayo, i-emulsifier ne-dispersant ngenxa yomsebenzi wayo osebenzayo osebenzayo kusisombululo sayo esinamanzi. Izibonelo zezicelo zayo zimi kanje:

1. Umphumela we-methylhydroxyethylcellulose ekusebenzeni kukasimende.Ibanga lokwakha i-MHEC i-methylHydroxyethylcellulose iyimpushana emhlophe engenaphunga, enganambitheki, engenabuthi engancibilika emanzini abandayo ukuze yakhe isixazululo se-viscous esisobala. Inezici zokuqina, ukubopha, ukuhlakazeka, i-emulsification, ukwakheka kwefilimu, ukumiswa, i-adsorption, i-gelation, umsebenzi ongaphezulu, ukugcinwa komswakama kanye ne-colloid evikelayo. Njengoba isixazululo esinamanzi sinomsebenzi osebenzayo ongaphezulu, singasetshenziswa njenge-colloid evikelayo, i-emulsifier ne-dispersant.Ibanga lokwakha i-MHEC i-methyl Hydroxyethyl cellulose isixazululo samanzi sine-hydrophilicity enhle futhi i-ejenti ephumelelayo yokugcina amanzi.
2. Lungiselela upende wokusiza ngokuguquguquka okuphezulu, owenziwe ngezingxenye ezilandelayo ngesisindo sezinto zokusetshenziswa: 150-200g yamanzi e-deionized; 60-70g ye-emulsion ye-acrylic ehlanzekile; 550-650g we-calcium enzima; 70-90 g ushukela; 30-40g ye-methyl cellulose isixazululo samanzi; I-10-20g yesisombululo samanzi se-lignocellulose; 4-6g wezinsiza zokwakha ifilimu; 1.5-2.5 g ye-antiseptic fungicide; 1.8-2.2g ye-disperant; 1.8-2.2g ye-ejenti yokumanzisa; I-Thickener 3.5-4.5g; i-ethylene glycol 9-11g; isixazululo samanzi sebanga Lokwakha i-MHEC senziwe nge-2-4% yebanga loKwakha i-MHEC encibilikiswe emanzini; ii-cellulose fiberisixazululo samanzi senziwe nge-1 -3%i-cellulose fiberyenziwa ngokuncibilika emanzini.

Indlela yokukhiqizaIbanga lokwakha i-MHEC?

IukukhiqizwaIndlela Yokwakha Ibanga le-MHEC i-methyl hydroxyethyl cellulose ukuthi ukotini ocolisisiwe usetshenziswa njengempahla eluhlaza futhi i-ethylene oxide isetshenziswa njenge-ejenti etherifying ukulungiselela Ibanga Lokwakha i-MHEC. Izinto zokusetshenziswa zokulungiselela Ibanga Lokwakha i-MHEC zilungiswa ngezingxenye ngesisindo: izingxenye ezingama-700-800 ze-toluene nengxube ye-isopropanol njenge-solvent, izingxenye ezingama-30-40 zamanzi, izingxenye ezingama-70-80 ze-sodium hydroxide, izingxenye ezingama-80-85 zikakotini ocwengekile, indandatho 20-28 izingxenye oxyethane, 80-90 izingxenye methyl chloride, 16-19 izingxenye glacial acetic acid; izinyathelo eziqondile zimi kanje:

Esinyathelweni sokuqala, engeza ingxube ye-toluene ne-isopropanol, amanzi, ne-sodium hydroxide ku-kettle yokusabela, phakamisa izinga lokushisa libe ngu-60-80 ° C, bese uyigcina imizuzu engu-20-40;

Isinyathelo sesibili, i-alkalization: pholisa izinto ezingenhla ku-30-50°C, engeza ukotini ocolisisiwe, fafaza ngengxube ye-toluene ne-isopropanol, phuma uye ku-0.006Mpa, ugcwalise nge-nitrogen ukuze uthole okunye oku-3, bese wenza ama-alkali ngemva kokushintsha Izimo ze-alkalization. zimi kanje: isikhathi se-alkalization amahora angu-2, futhi izinga lokushisa le-alkalization lingu-30 ℃-50℃;

Isinyathelo sesithathu, i-etherification: ngemuva kwe-alkalization, i-reactor ikhishwa iye ku-0.05～I-0.07MPa, i-ethylene oxide ne-methyl chloride iyengezwa futhi igcinwa isikhathi esingu-30～imizuzu engu-50; Isigaba sokuqala se-etherification: 40～60℃, 1.0～Amahora angu-2.0, ingcindezi ilawulwa phakathi kuka-0.15-0.3Mpa; Isigaba sesibili se-etherification: 60～90℃, 2.0～Amahora angu-2.5, ingcindezi ilawulwa phakathi kuka-0.4-0.8Mpa;

Isinyathelo sesine, ukungathathi hlangothi: engeza i-acetic acid enemitha yemitha kusengaphambili ku-desolventizer, cindezela ku-etherified material for neutralization, andise izinga lokushisa libe ngu-75.～80℃ ukuze kuncibilike, izinga lokushisa lizokhuphukela ku-102℃, futhi inani le-pH liyoba ngu-68. Uma ukuchithwa sekuqediwe; gcwalisa igedlela lokuchithwa ngamanzi kampompi aphathwe idivayisi ye-osmosis engemuva ku-90 ℃～100℃;

Isinyathelo sesihlanu, ukugeza kwe-centrifugal: izinto ezisesinyathelweni sesine ziyi-centrifuged nge-screw centrifuge enezingqimba, futhi izinto ezihlukanisiwe zidluliselwa ku-kettle yokugeza egcwele amanzi ashisayo kusengaphambili ukuze kugezwe izinto;

Isinyathelo sesithupha, ukomiswa kwe-centrifugal: izinto ezigeziwe zithuthelwa esomisini ngokusebenzisa i-screw centrifuge enezingqimba, izinto zomisiwe ku-150-170 ° C, futhi izinto ezomile zichotshozwa futhi zihlanganiswe.

Uma kuqhathaniswa nobuchwepheshe obukhona bokukhiqiza i-cellulose ether, bamanjeindlela yokukhiqizaisebenzisa i-ethylene oxide njenge-ejenti e-etherifying ukuze ilungiselele Ibanga Lokwakha i-MHEC i-methyl hydroxyethyl cellulose, futhi ngenxa yokuthi iqukethe amaqembu e-hydroxyethyl, inekhono elihle le-antifungal. Ukuzinza okuhle kwe-viscosity kanye nokumelana nesikhutha ngesikhathi sokugcina isikhathi eside. Ingashintsha amanye ama-cellulose ether.

Bfunda ibanga le-MHECi-cellulose ether derivatives,I-Cellulose ether iwumsebenzi wamakhemikhali we-polymer omuhle onokusetshenziswa okubanzi okwenziwe nge-polymer cellulose yemvelo ngokwelashwa ngamakhemikhali. Njengoba i-cellulose nitrate ne-cellulose acetate kwenziwa ngekhulu le-19, osokhemisi basungule uchungechunge oluningi lokuphuma kokuphuma kwe-cellulose kuma-cellulose ethers. Izinkambu zezicelo ezintsha zihlale zitholwa futhi imikhakha eminingi yezimboni iyabandakanyeka. Imikhiqizo ye-cellulose ether efana ne-sodium carboxymethyl cellulose (CMC), i-ethyl cellulose (EC), i-hydroxyethyl cellulose (HEC), i-hydroxypropyl cellulose (HPC), i-methyl hydroxyethyl cellulose (MHEC) kanye ne-methyl hydroxypropyl cellulose (MHPC) namanye ama-cellulose ethers aziwa ngokuthi. "i-industrial monosodium glutamate" kanye nebanga lokwakha i-MHEC isetshenziswe kabanzi ekunamathiseleni amathayela, udaka olomile, usimende kanye nama-gypsum plasters njll.
