01 Okukhulu
ukuqina:Ngemva kokuncibilika noma ukuhlakazwa emanzini, kungakhuphula i-viscosity yoketshezi futhi kugcine inhlanganisela eqinile ye-hydrophilic polymer ohlelweni. Isakhiwo samangqamuzana siqukethe amaqembu amaningi e-hydrophilic, afana -0H, -NH2, -C00H, -COO, njll., Angakwazi ukuphuza ngama-molecule amanzi ukuze enze isisombululo se-macromolecular esiphezulu se-viscosity. Ama-thickeners adlala indima ebalulekile izimonyo , ngokuqina, i-emulsifying, ukumisa, ukuqiniswa neminye imisebenzi.
02 Isimiso sesenzo esishubile
Njengoba amaqembu asebenzayo ochungechungeni lwe-polymer ngokuvamile awawodwa, indlela yokujiya imvamisa ukuthi i-thickener eyodwa inezinqubo ezimbalwa zokujiya.
Ukuqina kokuqina kwe-chain: Ngemuva kokuthi i-polymer ifakwe ku-solvent, amaketanga e-polymer ayagoqwa futhi ahlanganiswe elinye nelinye. Ngalesi sikhathi, i-viscosity yesisombululo iyanda. Ngemuva kokungathathi hlangothi nge-alkali noma i-amine ephilayo, ukushaja okungalungile kune-solubility eqinile yamanzi, okwenza uchungechunge lwe-polymer lube lula ukwandisa, ngaleyo ndlela kuzuzwe ukwanda kwe-viscosity. .
Ukuqina okuxhumene ngokuhlangene:I-Covalent crosslinking ukushumeka ngezikhathi ezithile kwama-monomers angasebenzi kahle angasabela ngamaketango amabili e-polymer, axhumanise ama-polymer amabili ndawonye, aguqule ngokuphawulekayo izici ze-polymer, kanye nokuba nekhono elithile lokumiswa ngemva kokuncibilika emanzini.
Ukuqina kwenhlangano:Iwuhlobo lwe-polymer encibilika emanzini e-hydrophobic, enezici zohlobo lwe-surfactant. Ukugxila kwe-polymer emanzini kukhulisa ukuhlangana phakathi kwama-molecule, futhi kusebenzisana neqembu le-hydrophobic le-polymer phambi kwe-surfactant, ngaleyo ndlela yakhe indawo esebenzayo Ama-micelles Ahlanganisiwe we-ejenti kanye namaqembu e-polymer hydrophobic, ngaleyo ndlela andise i-viscosity yesisombululo.
03 Ukuhlukaniswa kwama-thickeners
Ngokuvumelana nokuncibilika kwamanzi, ingahlukaniswa ibe: i-thickener encibilikayo emanzini kanye ne-micropowder thickener. Ngokusho komthombo we-thickener ungahlukaniswa ube: i-thickener yemvelo, i-synthetic thickener. Ngokusho kwesicelo, ingahlukaniswa: i-thickener-based water-based, i-thickener-based based thickener, i-acidic thickener, i-alkaline thickener.

04Ama-thieners ajwayelekile
1. I-thickener yemvelo encibilikayo emanzini
isitashi:Ijeli ingakhiwa emanzini ashisayo, i-hydrolyzed ngama-enzyme kuqala ku-dextrin, bese kuba i-maltose, futhi ekugcineni i-hydrolyzed ngokugcwele ibe ushukela. Kwezimonyo, ingasetshenziswa njengengxenyeyempushana eluhlazaizinto ezitholakala emikhiqizweni yempushana yezimonyo nezinamatheliso ku-rouge. kanye nama-thickeners.
i-xanthan gum:Incibilika kalula emanzini abandayo nasemanzini ashisayo, inokumelana ne-ion, futhi ine-pseudoplasticity. I-viscosity iyancishiswa kodwa iyatholakala ngaphansi kokugunda. Ivame ukusetshenziswa njenge-thickener kumaski obuso, ama-essence, ama-toners namanye ama-ejenti amanzi. Isikhumba sizwakala sibushelelezi futhi sigwema isinongo. I-ammonium preservatives isetshenziswa ndawonye.
I-Sclerotin:Ijeli yemvelo engu-100%, isixazululo se-scleroglucan sinokuzinza okukhethekile ekushiseni okuphezulu, sinokusebenza okuhle ezinhlobonhlobo zamanani we-pH, futhi sinokubekezelela okukhulu kwama-electrolyte ahlukahlukene esixazululweni. Inezinga eliphezulu le-pseudoplasticity, futhi i-viscosity yesisombululo ayishintshi kakhulu ngokukhuphuka nokuwa kwezinga lokushisa. Inomphumela othile wokuthambisa kanye nomuzwa omuhle wesikhumba, futhi ivame ukusetshenziswa kumaski obuso kanye nengqikithi.
Gum Gum:Incibilika ngokuphelele emanzini abandayo nashisayo, kodwa ayincibiliki emafutheni, kugrisi, kuma-hydrocarbon, ama-ketone nama-esters. Ingahlakazwa emanzini ashisayo noma abandayo ukuze yenze uketshezi lwe-viscous, i-viscosity ye-1% yesisombululo samanzi ngu-3 ~ 5Pa · s, futhi isisombululo ngokuvamile asikwazi ukungena.
i-sodium alginate:Uma i-pH = 6-9, i-viscosity izinzile, futhi i-alginic acid ingenza imvula ye-colloidal nge-calcium ions, futhi ijeli ye-alginic acid ingancipha endaweni ene-acidic.
i-carrageenan:I-Carrageenan inokumelana ne-ion okuhle futhi ayingenwa kalula yi-enzymatic njengokuphuma kokuphuma ku-cellulose.
2. I-semi-synthetic water-soluble thickener
I-methylcellulose:MC, amanzi akhukhumala abe isixazululo se-colloidal esicacile noma esincane. Ukuze uncibilikise i-methylcellulose, qala uyihlakaze ngenani elithile lamanzi uma ingaphansi kwezinga lokushisa lejeli, bese ufaka amanzi abandayo.
I-Hydroxypropylmethylcellulose:I-HPMC iyi-thickener engeyona i-ionic, ekhukhumala ibe yisisombululo se-colloidal esicacile noma esincane emanzini abandayo. Inomphumela omuhle wokukhulisa igwebu futhi uzinzise ohlelweni lokuwasha uketshezi, ithuthukisa ukungaguquguquki kwesistimu, futhi inomphumela we-synergistic nama-cationic conditioners, ithuthukisa ngempumelelo ukusebenza kwe-Wet combing, i-alkali ingasheshisa izinga lokuchithwa kwayo, futhi ikhulise kancane i-viscosity, i-hydroxypropyl methylcellulose izinzile kusawoti ojwayelekile, kodwa lapho ukugxila kwesisombululo sikasawoti kuphezulu, i-viscosity yesisombululo se-hydroxypropyl methylcellulose izonciphisa ukuthambekela kokwanda.
I-sodium carboxymethyl isitashi:CMC-Na, lapho idigri yokushintsha likhulu kuno-0.5, inyibilika kalula emanzini ukuze yakhe i-colloid ekhanyelayo; I-CMC enezinga lokushintsha elingaphansi kuka-0.5 ayincibiliki emanzini, kodwa ingancibilika kusisombululo esinamanzi ane-alkali. I-CMC ivame ukuba khona ngendlela yama-multi-molecular aggregates emanzini, futhi i-viscosity iphezulu kakhulu. Njengoba izinga lokushisa likhuphuka, i-viscosity iyancipha. Lapho i-pH ingu-5-9, i-viscosity yesisombululo izinzile; lapho i-pH ingaphansi kuka-3, i-hydrolysis iyenzeka ngenkathi kunemvula; lapho i-pH ingaphezu kuka-10, i-viscosity iyancipha kancane. I-viscosity yesisombululo se-CMC nayo izokwehla ngaphansi kwesenzo sama-microorganisms. Ukwethulwa kwama-ion e-calcium esixazululweni samanzi se-CMC kuzodala i-turbidity, futhi ukwengezwa kwama-ion ensimbi anevalent ephezulu njenge-Fe3+ ne-Al3+ kungabangela i-CMC ukuba imvula noma yakhe ijeli. Ngokuvamile, unama uma kuqhathaniswa.
I-Hydroxyethyl cellulose:I-HEC, i-thickener, i-ejenti emisiwe. Inganikeza izakhiwo ezinhle ze-rheology, ukwenza ifilimu kanye nokuthambisa. Ukuzinza okuphezulu, ukuzwa kwesikhumba okunamathelayo, ukumelana ne-ion enhle kakhulu, ngokuvamile kunconywa ukuthi uhlakazeke emanzini abandayo bese ushisa futhi ugovuze ukuze uncibilike ngendlela efanayo.
I-PEG-120 Methyl Glucose Dioleate:Isetshenziswa ngokukhethekile njenge-thickener ye-shampoo, ijeli yokugeza, isihlanzi sobuso, isicoci sezandla, imikhiqizo yokuwasha yezingane, kanye neshampoo engakhiphi izinyembezi. Isebenza kangcono kwamanye ama-surfactants okunzima ukuwajiya, futhi i-PEG-120 methyl glucose dioleate ayicasuli emehlweni. Ilungele i-shampoo yezingane kanye nemikhiqizo yokuhlanza. Isetshenziswa kuma-shampoos, izihlanzi zobuso, i-AOS, usawoti we-sodium we-AES, usawoti we-sulfosuccinate kanye nama-amphoteric surfactants asetshenziswa kujeli yokugeza anemiphumela emihle yokuhlanganisa nokujiya,
