Pankhani ya kusungunuka kwa methyl cellulose, makamaka imatanthawuza kusungunuka kwa sodium carboxymethyl cellulose.
Sodium carboxymethyl cellulose ndi ufa woyera kapena wachikasu wa flocculent fiber, wopanda fungo komanso wosakoma.Imasungunuka mosavuta m'madzi ozizira kapena otentha, ndikupanga njira yowonekera ndi mamasukidwe ena.
Kodi kusungunuka ndi chiyani?M'malo mwake, amatanthauza kuchuluka kwa solute kusungunuka ndi chinthu china cholimba mumkhalidwe wodzaza mu 100g ya zosungunulira pa kutentha kwina.Izi ndi kusungunuka.Kusungunuka kwa methyl cellulose kumakhudzana ndi mbali ziwiri.Kumbali imodzi, zimatengera mawonekedwe a carboxymethyl cellulose, ndipo kumbali ina, imakhala ndi ubale pang'ono ndi kutentha kwakunja, chinyezi, kupanikizika, mtundu wa zosungunulira, etc. The solubility ya carboxymethyl cellulose nthawi zambiri imakhudzidwa kwambiri ndi kutentha, ndipo chidzawonjezeka ndi kuwonjezeka kwa kutentha.
Pali njira zitatu zosungunulira methylcellulose:
1. Njira ya organic zosungunulira zosungunulira.Njira imeneyi makamaka kumwazikana kapena chonyowa MC organic solvents monga Mowa ndi ethylene glycol pasadakhale, ndiyeno kuwonjezera madzi kupasuka.
2. Njira yamadzi otentha.Chifukwa MC sisungunuka m'madzi otentha, MC imatha kumwazikana m'madzi otentha poyambira.Pozizira, njira ziwiri zotsatirazi zitha kutsatiridwa:
(1) Choyamba mungawonjezere madzi otentha okwanira m’chidebe ndi kutenthetsa kufika pafupifupi 70°C.MC idawonjezeredwa pang'onopang'ono ndikuyambitsa pang'onopang'ono, pang'onopang'ono kupanga slurry, yomwe idakhazikika ndikuyambitsa.
(2) Onjezani 1/3 ya madzi ofunikira mu chidebe chokhazikika, kutentha mpaka 70 ° C, ndi kumwaza MC molingana ndi njira yomwe tatchulayi, kenako konzani madzi otentha slurry;kenaka yikani madzi ozizira Pitani ku slurry, gwedezani bwino ndikuziziritsa kusakaniza.
3. Njira yosakaniza ufa.Njira imeneyi ndi makamaka kumwazikana MC ufa particles ndi ofanana ufa zosakaniza ndi youma kusanganikirana, ndiyeno kuwonjezera madzi kupasuka.
