Hydroxypropyl Methyl Cellulose HPMC
1. E na le botsitso bakeng sa acid le alkali, 'me tharollo ea eona ea metsi e tsitsitse haholo ka pH = 2 ~ 12 range.Soda ea Caustic le metsi a lime ha li na phello e ngata ts'ebetsong ea eona, empa alkali e ka potlakisa sekhahla sa ho qhibiliha le ho ntlafatsa hanyenyane viscosity.
2. HPMCke ntho e sebetsang hantle ea ho boloka metsi bakeng saseretse se ommengtsamaiso, e leng ho ka fokotsa lebelo la seretse secretion le stratification, ntlafatsa cohesiveness tsa seretse, ka katleho thibela sebopeho sa seretse mapetsong a polasetiki, le ho fokotsa seretse seretse cracking index.
3, ke electrolyte e seng ea ionic le e seng polymeric, e tsitsitseng haholo ka tharollo ea metsi a letsoai la tšepe le li-electrolyte tsa organic, 'me e ka ekeletsoa ho thepa ea mohaho ka nako e telele ho netefatsa hore nako e telele ea eona e ntlafatsoa.
4, ts'ebetso ea ho sebetsa ea seretse e ntlafalitsoe haholo, seretse se bonahala se na le "oliness", se ka etsa hore lerako le kopane le tletse, le boreleli, e le hore seretse le setsi sa motheo se tiee, 'me se khone ho lelefatsa nako ea ts'ebetso.
Ho boloka metsi
Ho phethahala ha pholiso ea ka hare ho thusa ntlafatso ea matla a nako e telele, thibelo ea ho tsoa mali, thibelo ea seretse, ho honyela le ntlafatso ea ho thibela ho phatloha ha seretse.
Ho teteana
Thibela karohano, ntlafatsa ho ts'oana ha seretse, ntlafatsa matla a maqhama a metsi, le ho ntlafatsa ts'ebetso e khahlanong le ho leketla.
Ho kenya moea
Ho ntlafatsa ts'ebetso ea seretse.Ha viscosity ea cellulose e ntse e phahama, ha ketane ea molek'hule e le telele, ho hlakile haholoanyane phello ea moea e kenang.
Coagulation e liehang
Sebelisana le ho boloka metsi ho eketsa nako ea ho bula seretse
Hydroxypropyl Starch ether
1. Lintho tse phahameng tsa hydroxypropyl ka starch ether li fana ka tsamaiso e tsitsitseng ea hydrophilicity, ho fetola metsi a sa lefelloeng hore e be metsi a tlamiloeng, a phethang karolo e ntle ea ho boloka metsi.
2. Li-ether tsa starch tse nang le likahare tse fapaneng tsa hydroxypropyl li na le bokhoni bo fapaneng ba ho thusa cellulose ho boloka metsi ka tekanyo e tšoanang.
3. Ho nkela sebaka sa sehlopha sa hydroxypropyl ho eketsa tekanyo ea ho ruruha metsing le ho hatella sebaka sa phallo ea likaroloana, kahoo ho finyella phello ea ho teteka le ho eketseha ha viscosity.
Thixotropic lubricity
Starch ether e qhalakanngoa ka potlako tsamaisong ea seretse, e fetola rheology ea seretse le ho e fa thixotropy.Ha matla a ka ntle a sebelisoa, viscosity ea seretse e tla fokotseha, ho etsa bonnete ba hore mohaho o motle le ho pompa, le ho o fa thixotropy.E na le maikutlo a boreleli.Ha matla a ka ntle a tlosoa, viscosity ea eketseha, e leng se fanang ka seretse se hanyetsanang hantle le ho fokotseha.Har'a li-putty powders, e na le melemo ea ho ntlafatsa khanya ea oli ea putty le ho benya ho khanyang.
Phello e thusang ea ho boloka metsi
Starch ether ka boeona e na le thepa ea hydrophilic ka lebaka la karolo ea lihlopha tsa hydroxypropyl tsamaisong.Ha e kopantsoe le selulose kapa e kenngoa ka tekanyo e itseng ho seretse, e ka eketsa ho boloka metsi ho isa tekanyong e itseng le ho ntlafatsa nako ea ho omisa holim'a metsi.
Anti-sag le anti-slip
Phello e ntle ea anti-sag le phello ea sebopeho.
Phofo ea polymer e ka qhaloang hape
1. Ntlafatsa ho sebetsa ha seretse.Phofo e qhalakantsoeng haper or RDPlikaroloana li qhalakanngoa tsamaisong, ho fana ka tsamaiso e ntle ea metsi le ho ntlafatsa ho sebetsa le ho sebetsa ha seretse.
2. Ntlafatsa matla a maqhama a seretse.Ka mor'a hore phofo ea rabara e qhalakane ka filimi, lintho tse sa tloaelehang le tse phelang tsamaisong ea seretse li ka kopanngoa hammoho.Ho ka nahanoa hore samente le lehlabathe seretseng ke masapo, 'me phofo ea latex e etsa li-ligaments.Ho kopana hoa eketseha, matla a eketseha, 'me mohaho o tenyetsehang o thehoa butle-butle.
3. Ntlafatsa ho hanyetsa boemo ba leholimo ba seretse.Freeze-thaw resistant latex powder ke resin ea thermoplastic e nang le mekhoa e metle, e ka nolofalletsang seretse ho arabela liphetohong tse ka ntle ho batang le mocheso, ka katleho ho thibela seretse ho senya ka lebaka la ho fetoha ha mocheso.
4. Ntlafatsa matla a flexural a seretse.Polymer le seretse sa samente li theha melemo e tlatselletsang.Ha mapetsong a bakoa ke matla a ka ntle, polymer e ka pharalla mapetsong 'me ea thibela ho atolosoa ha mapetsong, ka tsela eo ho ntlafatsa ho tiea ha fracture le ho senyeha ha seretse.
