Ibanga lokwakha iMHEC

Ibanga lokwakha I-MHEC

Ibanga lokwakha iMHEC Methyl HydroxyethylCillulosengumgubo omhlophe ongenavumba, ongenancasa, ongenatyhefu onokunyibilika emanzini abandayo ukwenza isisombululo se-viscous esicacileyo. Ineempawu zokuqina, ukudibanisa, ukusabalalisa, i-emulsification, ukubunjwa kwefilimu, ukumiswa, i-adsorption, i-gelation, umsebenzi ophezulu, ukugcinwa komswakama kunye ne-colloid yokukhusela. Ekubeni isisombululo esinamanzi sinomsebenzi osebenzayo, sinokusetyenziswa njenge-agent ekhuselayo ye-colloidal, i-emulsifier kunye ne-dispersant. Ibakala lokwakha i-MHEC i-methyl Hydroxyethylcellulose isisombululo se-aqueous sine-hydrophilicity elungileyo kwaye sisixhobo esisebenzayo sokugcina amanzi. I-Hydroxyethyl methyl cellulose iqulethe amaqela e-hydroxyethyl, ngoko inamandla okumelana nokungunda, ukuzinza okuhle kwe-viscosity kunye ne-anti-mildew ngexesha lokugcinwa kwexesha elide.

Iimpawu zomzimba kunye neekhemikhali:

Ukubonakala: I-MHEC imhlophe okanye iphantse imhlophe i-fibrous okanye ipowder granular; engenavumba.

I-Solubility: I-MHEC inokunyibilika emanzini abandayo kunye namanzi ashushu, imodeli ye-L inokuchithwa kuphela kumanzi abandayo, i-MHEC ayinakuchithwa kwiintlobo ezininzi ze-solvents eziphilayo. Emva kokunyanga kwendawo, i-MHEC ihlakaza emanzini abandayo ngaphandle kwe-agglomeration, kwaye ichithe ngokukhawuleza, kodwa inokuchithwa ngokukhawuleza ngokulungelelanisa ixabiso layo le-PH ye-8 ~ 10.

Ukuzinza kwe-PH: I-viscosity itshintsha kancinci ngaphakathi kwinqanaba le-2 ~ 12, kwaye i-viscosity iyancipha ngaphaya kolu luhlu.

I-Granularity: i-40 mesh pass rate ≥99% 80 ireyithi yokupasa i-mesh 100%.

Ubuninzi obubonakalayo: 0.30-0.60g / cm3.

Isicelo 

Ibanga lokwakha i-MHEC i-methyl Hydroxyethyl cellulose ingasetyenziselwa njenge-colloid ekhuselayo, i-emulsifier kunye ne-dispersant ngenxa yomsebenzi wayo osebenzayo osebenzayo kwisisombululo sayo samanzi. Imizekelo yezicelo zayo yile ilandelayo:

1. Umphumo we-methylhydroxyethylcellulose ekusebenzeni kwe-samente.Ibakala lokwakha i-MHEC i-methylHydroxyethylcellulose i-odorless, i-tasteless, i-powder emhlophe engenazo inetyhefu enokuthi inyibilike emanzini abandayo ukwenza isisombululo se-viscous esicacileyo. Ineempawu zokuqina, ukudibanisa, ukusabalalisa, i-emulsification, ukubunjwa kwefilimu, ukumiswa, i-adsorption, i-gelation, umsebenzi ophezulu, ukugcinwa komswakama kunye ne-colloid yokukhusela. Ekubeni isisombululo esinamanzi sinomsebenzi osebenzayo, sinokusetyenziswa njenge-colloid ekhuselayo, i-emulsifier kunye ne-dispersant.Ibakala lokwakha i-MHEC i-methyl Hydroxyethyl cellulose isisombululo esine-hydrophilicity esihle kwaye sinomsebenzi osebenzayo wokugcina amanzi.
2. Lungiselela ipeyinti yokunceda kunye nokuguquguquka okuphezulu, okwenziwe ngamacandelo alandelayo ngobunzima bezinto ezibonakalayo: 150-200g yamanzi adibeneyo; I-60-70g ye-emulsion ye-acrylic ecocekileyo; 550-650g ye-calcium enzima; 70-90g ye-talc; 30-40g ye-methyl cellulose isisombululo samanzi; I-10-20g ye-lignocellulose isisombululo samanzi; I-4-6g yezixhobo zokwenza ifilimu; 1.5-2.5g 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; Isisombululo samanzi se-MHEC se-MHEC senziwe nge-2-4% ye-MHEC yoKwakha ibakala elichithwe emanzini; ii-cellulose fiberUmxube omanzi wenziwe nge-1 -3%i-cellulose fiberyenziwa ngokunyibilika emanzini.

Indlela yokuvelisaIbanga lokwakha iMHEC?

Iimvelisoindlela yoKwakha ibakala le-MHEC i-methyl hydroxyethyl cellulose kukuba ikotoni ecocekileyo isetyenziswe njengento eluhlaza kunye ne-ethylene oxide isetyenziswe njenge-etherifying agent ukulungiselela i-Building grade MHEC. Izinto ezisetyenziswayo zokulungiselela i-MHEC yoKwakha i-MHEC zilungiswe kumacandelo ngobunzima: iindawo ze-700-800 ze-toluene kunye ne-isopropanol umxube njenge-solvent, i-30-40 iinxalenye zamanzi, i-70-80 ye-sodium hydroxide, i-80-85 i-cotton ecocekileyo; iringi 20-28 iinxalenye ze-oxyethane, 80-90 iinxalenye zemethyl chloride, 16-19 iinxalenye ze i-acetic acid; Amanyathelo athile ngala alandelayo:

Kwisinyathelo sokuqala, yongeza umxube we-toluene kunye ne-isopropanol, amanzi, kunye ne-sodium hydroxide kwi-kettle yokusabela, uphakamise izinga lokushisa kwi-60-80 ° C, kwaye uyigcine imizuzu engama-20-40;

Isinyathelo sesibini, i-alkalization: ukupholisa izinto ezingentla apha kwi-30-50 ° C, yongeza i-cotton ecocekileyo, i-spray ngomxube we-toluene kunye ne-isopropanol, ikhuphe kwi-0.006Mpa, igcwalise i-nitrogen yokutshintshwa kwe-3, kwaye wenze i-alkalis emva kokutshintshwa Iimeko ze-alkalization. zezi zilandelayo: ixesha le-alkalization ziiyure ezi-2, kwaye ubushushu be-alkalization yi-30 ℃-50℃;

Isinyathelo sesithathu, i-etherification: emva kwe-alkalization, i-reactor ikhutshelwa kwi-0.05～I-0.07MPa, i-ethylene oxide kunye ne-methyl chloride yongezwa kwaye igcinwe i-30～imizuzu engama-50; Inqanaba lokuqala lokuqina: 40～60℃, 1.0～Iiyure ze-2.0, uxinzelelo lulawulwa phakathi kwe-0.15-0.3Mpa; inqanaba lesibini lokuqina: 60～90℃, 2.0～Iiyure ze-2.5, uxinzelelo lulawulwa phakathi kwe-0.4-0.8Mpa;

Inyathelo lesine, ukungathathi hlangothi: yongeza i-acetic acid enemitha ye-acetic kwangaphambili kwi-desolventizer, cinezela kwi-etherified material for neutralization, ukwandisa ubushushu ukuya kuma-75.～80℃ ukwenzela ukunyibilika, iqondo lobushushu liya kunyuka liye kwi-102℃, kwaye ixabiso le-pH liya kuba ngu-68. Xa ukuchithwa kugqityiwe; Gcwalisa iketile yokutshatyalaliswa ngamanzi etephu aphathwa sisixhobo se-osmosis esingasemva kwi-90 ℃.～100℃;

Isinyathelo sesihlanu, ukuhlamba i-centrifugal: izinto ezikwinqanaba lesine zixutywe nge-screw centrifuge ene-horizontal screw, kwaye izinto ezihlukeneyo zidluliselwa kwi-kettle yokuhlamba ezaliswe ngamanzi ashushu kwangaphambili ukuze kuhlanjwe izinto;

Isinyathelo sesithandathu, ukomisa i-centrifugal: izinto ezihlanjiweyo zihanjiswa kwi-dryer ngokusebenzisa i-screw centrifuge ene-horizontal screw, izinto zomiswe kwi-150-170 ° C, kwaye izinto ezomileyo zityunyuziwe kwaye zipakishwe.

Xa kuthelekiswa neteknoloji yemveliso ye-cellulose ether ekhoyo, okwangokuindlela yokuvelisaisebenzisa i-ethylene oxide njenge-etherifying agent ukuze ilungiselele i-Building grade MHEC methyl hydroxyethyl cellulose, kwaye ngenxa yokuba iqukethe amaqela e-hydroxyethyl, inekhono elihle lokulwa ne-antifungal. Uzinzo oluhle lwe-viscosity kunye nokumelana nokubola ngexesha lokugcinwa kwexesha elide. Ingathatha indawo yezinye ii-ether ze-cellulose.

Binqanaba lokufunda le-MHECNgaba ivela kwi-cellulose ether,I-Cellulose ether yimathiriyeli yeekhemikhali ezintle zepolymer ezinoluhlu olubanzi losetyenziso olwenziwe kwi-cellulose ye-polymer yendalo ngonyango lwekhemikhali. Ukusukela ukuba i-cellulose nitrate kunye ne-cellulose acetate zenziwe ngenkulungwane ye-19, iikhemisti ziye zaphuhlisa uninzi lwee-cellulose derivatives ze-cellulose ethers. Iinkalo zezicelo ezintsha zihlala zifunyanwa kwaye amacandelo amaninzi amashishini abandakanyekayo. Iimveliso ze-cellulose ether ezifana ne-sodium carboxymethyl cellulose (CMC), i-ethyl cellulose (EC), i-hydroxyethyl cellulose (HEC), i-hydroxypropyl cellulose (HPC), i-methyl hydroxyethyl cellulose (MHEC) kunye ne-methyl hydroxypropyl cellulose (MHPC) kunye nezinye i-cellulose ethers zaziwa ngokuba "industrial monosodium glutamate" kunye nebakala lokwakha I-MHEC isetyenziswe ngokubanzi kwi-adhesive tile, udaka olomileyo, i-samente kunye ne-gypsum plasters njl.
