Hydroxylyl methyl semcinokusetyenziswa njengearhente yokhuselo, i-eulsifier kunye nokusasazeka ngenxa yomsebenzi wayo osebenzayo kwisisombululo esinamandla. Umzekelo wesicelo sayo ngolu hlobo lulandelayo: Isiphumo se-hydroxyythl methyl sellies kwipropathi yesamente. I-Hydroxylceyl Methylcelcelcelse i-odolt i-odolt, engenaxabiso, i-powble emhlophe enetyhefu ekwahlula amanzi abandayo ukwenza isisombululo esicacileyo, se-viscous. Inepropathi yokutyibilika, ukubopha, ukusasaza, ukonakalisa, ukwenza ifilimu, ukumisa ifilimu, i-adsorbling, ukugcinwa komswakama kunye nokukhusela i-colloids kunye nokukhusela i-colloids kunye nokukhusela i-conloids kunye nokukhusela i-colloids kunye nokukhusela i-colloids kunye nokukhusela i-conloids kunye nokukhusela i-conloids kunye nokukhusela i-conloids kunye nokukhusela umswakama kunye nokukhusela i-colloids kunye nokukhusela i-colloids kunye nokukhusela umswakama kunye nokukhusela i-colloids kunye nokukhusela i-colloids kunye nokukhusela umswakama kunye nokukhusela i-colloids kunye nokukhusela umswakama kunye nokukhusela i-colloids. Ngenxa yomsebenzi osebenzayo wesisombululo esinamandla, inokusetyenziswa njengearhente yokukhusela i-colloid, i-mulsifier kunye nokusasazeka. I-HYDROXYETHyl Methyl Seleous Commose Commose I-Hydrophibility kwaye ingummeli osebenza kakuhle wokugcina amanzi.
lungiselela
Indlela yokulungiselela i-HydroxylMethyl Methyl Selelose, indlela isebenza usebenzisa i-cotton ecocekileyo njengezinto eziphantsi kunye ne-e-ithoy oxide njengearhente yokuphumelelahydroxylyl methyl seluplose. Izinto ezingafunekiyo zokulungiselela i-Hydroxyl Methyl Selelose ilungiselelwe amacandelo ngokomxube we-toluene kunye ne-Iyopropanol njenge-Soodium hydroxide, i-80-85 yeenxalenye ze Ikotoni ehlaziyiweyo, iinxalenye ezingama-20 ukuya kwengama-20 ukuya kwengama-80 ukuya kwi-80-90 ye-methyl chloride, kunye ne-16-16 yeenxalenye ze-acetic acid; amanyathelo athile:
Inyathelo lokuqala, kwi-rector, yongeza i-toluene kunye nomxube we-Isopropanol, kunye neSodium hydroxide, ifudumeze ukuya kwi-60 ~ 80 ~, ikhutshiwe imizuzu engama-20;
Inqanaba lesibini, i-alkalition: Phola le nto ingentla ukuya kwi-30 ~ 50 ℃, yongeza umxube we-Toutene kunye ne-Itropan yeSolvane nge-3, kwaye uqhubeke ne-alkali emva kokutshintsha i-alkalization Iimeko zezi zilandelayo: Ixesha le-alkalition liziiyure ezi-2, kwaye amaqondo obushushu e-alkali angama-30 ° C ukuya kwi-50 ° C;
Inqanaba lesithathu: Isivumelwano: I-alkalization igqityiwe, i-reactoring ikhutshwe kwi-0.05 ~ 0.07MPA, i-i-itholon oxide kwaye igcinwe imizuzu engama-30 ~ 50; Inqanaba lokuqala le-etheriya Inqanaba lesibini le-Etherheli: 60 ~ 90 ℃, 2.0 ~ iiyure eziyi-2.5, uxinzelelo lulawulwa phakathi kwe-0.40.8MPA;
Inyathelo le-4, ukungathathi cala: Yongeza i-acetic acetic acid kwi-ketele, cinezela kwi-75 ~ 80 ~ 80 ~, kunye nexabiso le-pH I-68 xa i-PATPIPE igqityiwe, itanki ye-PAK igcwaliswa ngamanzi e-PAP ephathwe nge-Ossosis ye-Osmosis kwi-90 ℃ ~ 100 ℃;
Inyathelo lesihlanu, ukuhlamba kwe-centrifugal: Izinto ezikwinqanaba lesine lifakwe kwi-Centrifuge ye-Centrifuge, kwaye izinto ezahluliweyo zidluliselwa kwi-ketele eshushu kwangaphambili, kwaye izinto ziyahlanjwa;
Inyathelo lesithandathu, iCentrifugal yomisa: Izinto ezihlanjwe zithuthwa kwi-certififuges ethe tyaba, umbandela womiswa nge-150-16 ° C, kwaye izinto ezomileyo zitsalwa kwaye zipakishwe.
Xa kuthelekiswa nakhoI-Selersese EtherItekhnoloji yemveliso, ukuntywila kwangoku, yamkela i-Ellene oxide njenge-Arhente ye-Eyerroxykyl Methyl Sellyl Sellyl Sellyl, kwaye unamafutha amnyama kunye nokunganyangeki kwe-villy ngexesha lokugcina ixesha elide. Inokusetyenziswa endaweni yokunye kweeselwase.
Ixesha leposi: Apri-25 ukuya ku-2424
