Sebopeho sa limolek'hule se na le lihlopha tse ngata tsa hydrophilic, tse kang -0H, -NH2, -C00H, -COO, joalo-joalo, tse ka khonang ho nosetsa ka limolek'hule tsa metsi ho etsa tharollo e phahameng ea viscosity macromolecular. Li-thickeners li phetha karolo ea bohlokoa ho litlolo , ka thickening, emulsifying, suspending, stabilizing le mesebetsi e meng.
02 Molao-motheo oa ketso ea Thickener
Kaha lihlopha tse sebetsang ka har'a ketane ea polymer ka kakaretso ha li le 'ngoe, mokhoa o teteaneng hangata ke hore motenya o le mong o na le mekhoa e mengata ea ho tenya.
Botenya ba ketane: Kamora hore polymer e kenngoe ka har'a solvent, liketane tsa polymer lia kobeha ebe lia hoholeha. Ka nako ena, viscosity ea tharollo ea eketseha. Ka mor'a ho se nke lehlakore ka alkali kapa amine ea manyolo, tefiso e mpe e na le ho qhibiliha ha metsi ka matla, e leng se etsang hore ketane ea polymer e be bonolo ho atolosa, kahoo e finyella ho eketseha ha viscosity. .
Covally cross-linked thickening: Covalent crosslinking ke ho kengoa nako le nako ha li-monomers tse sa sebetseng hantle tse ka sebetsanang le liketane tse peli tsa polymer, li hokahanya lipolima tse peli hammoho, ho fetola haholo thepa ea polymer, le ho ba le bokhoni bo itseng ba ho emisa kamora ho qhibiliha ka metsing.
Ho teteana ha mokhatlo: Ke mofuta oa polymer e qhibilihang ka metsing ea hydrophobic, e nang le litšobotsi tsa mofuta oa surfactant. Motsoako oa polymer ka metsing o eketsa setsoalle pakeng tsa limolek'hule, 'me o sebelisana le sehlopha sa hydrophobic sa polymer ka pel'a surfactant, kahoo e etsa sebaka se sebetsang sa motsoako oa li-micelles tsa moemeli le lihlopha tsa polymer hydrophobic, kahoo ho eketsa viscosity ea tharollo.

04 Li-thickeners tse tloaelehileng
1. Setenya sa tlhaho se qhibilihang ka metsing
starch:Gel e ka etsoa ka metsing a chesang, ea tšeloa ka hydrolyze ka li-enzyme pele ho dextrin, joale ka maltose, 'me qetellong ea hydrolyzed ka botlalo hore e be tsoekere. Ho litlolo, e ka sebelisoa e le karoloea phofo e talalisebelisoa lihlahisoa tsa phofo ea litlolo le li-adhesives ka rouge. le thickeners.
xanthan gum:E qhibiliha habonolo metsing a batang le metsing a chesang, e na le khanyetso ea ion, 'me e na le pseudoplasticity. Viscosity e fokotsehile empa e ka khutlisoa ha ho kuta. Hangata e sebelisoa e le motenya ho limaske tsa sefahleho, li-essences, toner le lisebelisoa tse ling tsa metsi. Letlalo le ikutloa le le boreleli 'me le qoba ho noa. Li-preservatives tsa ammonium li sebelisoa hammoho.
Sclerotin:Gel ea tlhaho ea 100%, tharollo ea scleroglucan e na le botsitso bo khethehileng mochesong o phahameng, e na le ts'ebetso e ntle ka mefuta e mengata ea litekanyetso tsa pH, 'me e na le mamello e kholo bakeng sa li-electrolyte tse fapaneng ka tharollo. E na le tekanyo e phahameng ea pseudoplasticity, 'me viscosity ea tharollo ha e fetohe haholo ka ho phahama le ho theoha ha mocheso.

2. Semi-synthetic e qhibilihang ka metsing
Methylcellulose:MC, metsi a ruruha ho ba tharollo ea colloidal e hlakileng kapa e nyenyane. Ho qhaqha methylcellulose, qala ka ho e qhalakanya ka tekanyo e itseng ea metsi ha e le tlase ho mocheso oa gel, ebe o eketsa metsi a batang.
Hydroxypropylmethylcellulose:HPMC ke non-ionic thickener, e ruruhileng ho ba tharollo e hlakileng kapa e nyenyane ea colloidal ka metsing a batang. E na le phello e ntle ea ho eketseha ha foam le ho tsitsisa tsamaisong ea ho hlatsoa metsi, e ntlafatsa ho tsitsisa ha tsamaiso, 'me e na le phello ea synergistic le li-conditioner tsa cationic, ka katleho e ntlafatsa ts'ebetso ea ho kopanya metsi, alkali e ka potlakisa sekhahla sa ho qhibiliha,' me ea eketsa hanyenyane. viscosity, hydroxypropyl methylcellulose e tsitsitse ho matsoai a tloaelehileng, empa ha motsoako oa tharollo ea letsoai o phahame, viscosity ea hydroxypropyl methylcellulose tharollo e tla fokotsa tloaelo ea ho eketseha.
Sodium carboxymethyl starch: CMC-Na, ha tekanyo ea ho nka sebaka e kholo ho feta 0.5, e qhibiliha habonolo metsing ho etsa colloid e bonaletsang; CMC e nang le sebaka se ka tlase ho 0.5 ha e qhibilihe ka metsing, empa e ka qhibiliha ka tharollo ea metsi a alkaline. CMC hangata e teng ka mokhoa oa li-aggregates tse ngata tsa limolek'hule metsing, 'me viscosity e phahame haholo. Ha mocheso o ntse o eketseha, viscosity e fokotseha. Ha pH e le 5-9, viscosity ea tharollo e tsitsitse; ha pH e le ka tlase ho 3, hydrolysis e etsahala ha pula e hlaha; ha pH e le kholo ho feta 10, viscosity e fokotseha hanyenyane. Viscosity ea tharollo ea CMC le eona e tla fokotseha tlasa ts'ebetso ea likokoana-hloko. Ho kenngoa ha li-ion tsa calcium ka har'a tharollo ea metsi a CMC ho tla baka moferefere, 'me ho eketsoa ha li-ion tsa tšepe tse phahameng tse kang Fe3+ le Al3+ ho ka etsa hore CMC e theohe kapa e thehe gel. Ka kakaretso, pente e batla e le thata.
Hydroxyethyl cellulose:HEC, thickener, moemeli ea emisang. E ka fana ka thepa e ntle ea rheology, filimi-forming le thepa e mongobo. Botsitso bo phahameng, boikutlo ba letlalo bo batlang bo khomarela, ho hanyetsa ion e ntle haholo, hangata ho kgothaletswa ho hasana ka metsing a batang ebe o futhumatsa le ho hlohlelletsa ho qhibiliha homogeneously.
PEG-120 Methyl Glucose Dioleate:E sebelisoa ka mokhoa o khethehileng joalo ka setlolo se teteaneng sa shampoo, gel ea shaoara, sehloekisi sa sefahleho, sanitizer ea letsoho, lihlahisoa tsa bana tse hlatsoang le shampoo e sa keng ea taboha. E sebetsa haholo ho li-surfactants tse ho leng thata ho li teteana, 'me PEG-120 methyl glucose dioleate ha e khopise mahlo. E loketse bakeng sa shampoo ea lesea le lihlahisoa tsa ho hloekisa. E sebelisoa ho li-shampoos, lihloekisi tsa sefahleho, AOS, letsoai la sodium la AES, letsoai la sulfosuccinate le li-amphoteric surfactants tse sebelisoang ka gel ea shaoara li na le litlamorao tse ntle tsa ho kopanya le ho tenya.
