Gusaba no gutegura HydroxyEthyyl Methyl Cellulose hemc

HydroxyEthyy Methyl Methyl Memc irashobora gukoreshwa nka agent agent ya Colloid, Emalifier kandi ikwirakwizwa kubera ibikorwa byayo bifatika mu gisubizo gikora. Urugero rwibisabwa ni ibi bikurikira: Ingaruka za HydroxyEthyyl Methyl Methyl Cellulose kumitungo ya sima. HydroxyEthyyl methylcellse ni ifu idafite impumuro nziza, idafite uburyohe, buto ishonga mumazi akonje kugirango akore igisubizo kiboneye, gishimishije. Ifite imitungo yo kubyimba, guhuza, gutatana, guhindagurika, gushiraho film, guhagarikwa, gukomera, kuguriza, kugumana ubushuhe no kurengera colloide. Bitewe nimikorere yubuso bwikibazo cyamazi, birashobora gukoreshwa nkabakozi ba colloid, emulsifier no kubarwayi. Hydroxyyethyy Methyl Cellulose igisubizo cy'amazi gifite hydrofili nziza kandi ni umukozi ugumana amazi menshi.

tegura
Uburyo bwo gutegura HydroxyIthyyl Methyl Cellulose, uburyo bugizwe no gukoresha ipamba itunganijwe nk'ibikoresho bya Ethylene mu rwego rwo gutegura HydroxyEthyl Methyl Cellulose. Ibikoresho fatizo byo gutegura HydroxyIthyl Methyl Methyl Methyl yateguwe mu bice n'uburemere bwa Toluene na Isobanol, ibice 80-40 bya oxyhane, na 16-19 ibice bya acide nziza; Intambwe Zihariye ni:

Intambwe yambere, muri reaction, ongeraho Toluene na Aripropal kuvanga, amazi, na sodium, na sodium hydroxide, ishyushye kugeza kuri 60 ~ 80 ℃, koresha iminota 20 ~ 40;

Intambwe ya kabiri, alkalisation: Cool Ibikoresho byavuzwe haruguru kugeza 30 ~ 50 ℃, bitera imvange ya toluene na 0.006Malisate ya Alkalisan, kandi ubushyuhe bwa alfalisation ni 30 ° C kugeza 50 ° C;

Intambwe ya gatatu, Guhanga: Alkalisation irarangiye, Realtor yimuwe kugeza kuri 0.05 ~ 0.07MPA, Etlon ofloride na methyl chloride yongeyeho, kandi yagumije iminota 30 ~ 50; Icyiciro cya mbere cyo guhindura: 40 ~ 60 ℃, 1.0 ~ 2.0 Isaha, igitutu kigenzurwa hagati ya 0.150.3mpa; Icyiciro cya kabiri cyo guhindura: 60 ~ 90 ℃, amasaha 2.0 ~ 7,000, igitutu kigenzurwa hagati ya 0.40.8mpa;

Intambwe ya 4, kutabogama: ongeraho aside iri mu mazi ya acetic hakiri kare isafuriya, kanda mu mazi ya 75 ~, ​​kandi ubushyuhe buriho bugera kuri 62 ℃, ikigega cy'imvura kigejejwe na metero osmose yavuwemo 90 ℃ ~ 100 ℃;

Intambwe ya gatanu, Centrifugal Gukaraba: Ibikoresho biri mu ntambwe ya kane biranyeganyega mu ndege za horizontal, kandi ibikoresho byatandukanijwe byimurirwa mu futle yuzuye amazi ashyushye, kandi ibikoresho byogejwe;

Intambwe ya gatandatu, centrifugal yumye: Ibikoresho byogejwe bitwarwa mumene unyuze mu gisirikare cya horizontal, ibikoresho byumye kuri 150-170 ° ku ya 150-170 ° C, kandi ibikoresho byumye birapakira kandi bipakiye.

Ugereranije na tekinoroji ya selile ya ether Irashobora gukoreshwa aho gukoresha abandi bahanganye.
