Poloko ea metsi eali-cellulose ethers
Ho boloka metsi a seretse ho bolela bokhoni ba seretse ho boloka le ho notlela mongobo.Ha viscosity ea cellulose ether e phahame, ho boloka metsi ho betere.Hobane sebopeho sa cellulose se na le li-hydroxyl le li-ether bond, athomo ea oksijene sehlopheng sa hydroxyl le ether bond e amahanngoa le molek'hule ea metsi ho etsa li-hydrogen bond, e le hore metsi a sa lefelloeng a fetohe metsi a tlamiloeng le ho tsamaisa metsi, kahoo a bapala karolo ea metsi. pokollo.
Solubility eacellulose ether
1. The coarser cellulose ether e qhalakanngoa habonolo ka metsing ntle le ho kopana, empa sekhahla sa ho qhibiliha se lieha haholo.Li-cellulose etherska tlas'a 60 mesh e qhibiliha ka metsing ka metsotso e ka bang 60.
2. Likaroloana tse ntle tsa cellulose ether li qhalakanngoa habonolo metsing ntle le agglomeration, 'me tekanyo ea ho qhibiliha e leka-lekane.Ho feta 80 meshcellulose ethere qhibiliha ka metsing ka metsotso e ka bang 3.
3. Ultra-fine cellulose ether e qhalana ka potlako metsing, e qhibiliha ka potlako, ’me e etsa viscosity e potlakileng.Ho feta 120 meshcellulose ethere qhibiliha ka metsing ka metsotsoana e ka bang 10-30.
Ha likaroloana tsa cellulose ether li le ntle, ho boloka metsi ho betere.Bokaholimo ba mahoasheCellulose Ether HEMCe qhibiliha hang ka mor'a ho kopana le metsi 'me e etsa ketsahalo ea gel.Sekhomaretsi se phuthela thepa ho thibela limolek'hule tsa metsi hore li se ke tsa tsoela pele ho kenella, 'me ka linako tse ling li ke ke tsa qhalakanngoa le ho qhibiliha ka mor'a nako e telele ea ho ferekanngoa, ho etsa tharollo ea flocculent e turbidized kapa caking.Likaroloana tse ntle hang-hang li qhalakanya le ho qhibiliha ha li kopana le metsi ho theha viscosity e tšoanang.
Moea oa cellulose ether
The aeration ea cellulose ether ke haholo-holo hobane cellulose ether e boetse e le mofuta oa surfactant, 'me mosebetsi oa sefahleho oa cellulose ether o etsahala haholo-holo sebopeho se tiileng sa khase, sa pele ka ho hlahisa li-bubble, ho lateloa ke ho hasana le ho kolobisa.Li-cellulose ethers li na le lihlopha tsa alkyl, tse fokotsang tsitsipano ea holim'a metsi haholo le matla a sefahleho sa metsi, e leng se etsang hore tharollo e nang le metsi e hlahise habonolo lipulumo tse ngata tse nyenyane tse koetsoeng nakong ea pherekano.
Gelatincity ea cellulose ethers
Ka mor'a hore cellulose ether e qhibilihe ka har'a seretse, sehlopha sa methoxy le sehlopha sa hydroxypropyl se ka har'a ketane ea molek'hule se tla kopana le li-ion tsa khalsiamo le aluminium ka har'a slurry ho etsa gel ea viscous le ho tlatsa sekheo sa seretse sa samente, ho ntlafatsa tšubuhlellano ea seretse. seretse le ho bapala karolo ea ho tlatsa habonolo le ho matlafatsa.Leha ho le joalo, ha matrix a kopantsoeng a hatelloa, polymer e ke ke ea bapala karolo e thata ea ho tšehetsa, kahoo matla le ho mena ha seretse ho fokotseha.
