01 Thickener
ujiya:Emva kokuchithwa okanye ukuchithwa emanzini, kunokunyusa i-viscosity yolwelo kunye nokugcina i-hydrophilic polymer compound ezinzileyo kwinkqubo. Isakhiwo se-molecular siqukethe amaqela amaninzi e-hydrophilic, afana -0H, -NH2, -C00H, -COO, njl., Enokuthi ifake i-hydrate ngamamolekyuli amanzi ukwenza isisombululo se-macromolecular esiphezulu se-viscosity. I-Thickeners idlala indima ebalulekileyo izimonyo , kunye nokuqina, i-emulsifying, ukumisa, ukuzinzisa kunye neminye imisebenzi.
02 Umgaqo-siseko wesenzo esityebileyo
Kuba amaqela asebenzayo kwitsheyina lepholima ayingowodwa, indlela yokujiya ikholisa ukuba isingqimba esinye sineendlela ezininzi zokujiya.
Ukujiya kwetsheyini ukujiya: Emva kokuba i-polymer ifakwe kwi-solvent, amatsheyina e-polymer ajikelezwe kwaye adityaniswe omnye nomnye. Ngeli xesha, i-viscosity yesisombululo iyanda. Emva kokungathathi hlangothi kunye ne-alkali okanye i-amine ye-organic, umrhumo ongalunganga une-solubility eqinile yamanzi, eyenza i-polymer chain chain ibe lula ukwandisa, ngaloo ndlela ifezekisa ukwanda kwe-viscosity. .
Ukujiya okudityanisiweyo ngokudibeneyo:I-Covalent crosslinking kukufakelwa kwamaxesha okuzinzisa iimonomers ezisebenza kabini ezinokusabela ngamatyathanga amabini epholima, ezinxibelelanisa iipholima ezimbini kunye, zitshintshe kakhulu iipropathi zepolymer, kunye nokuba nobuchule obuthile bokunqunyanyiswa emva kokunyibilikiswa emanzini.
Ukuqina kombutho:Luhlobo lwepolymer enyibilikayo yamanzi e-hydrophobic, eneempawu zohlobo lwe-surfactant. Ukuxinwa kwepolymer emanzini kwandisa umbutho phakathi kweeamolekyu, kwaye isebenzisana neqela le-hydrophobic ye-polymer phambi kwe-surfactant, ngaloo ndlela yenza umphezulu osebenzayo Imicelles edibeneyo ye-arhente kunye namaqela e-polymer hydrophobic, ngaloo ndlela ukwandisa isisombululo se-viscosity.
03Ukuhlelwa kwee-thickeners
Ngokokunyibilika kwamanzi, inokohlulwa ibe: i-thickener enyibilikayo yamanzi kunye ne-micropowder thickener. Ngokutsho komthombo we-thickener unokwahlulwa ibe: i-thickener yendalo, i-synthetic thickener. Ngokutsho kwesicelo, inokwahlulwa ibe: i-thickener-based-thickener, i-oyile-based thickener, i-acidic thickener, i-alkaline thickener.

04Izityebi eziqhelekileyo
1. I-thickener yendalo enyibilikayo emanzini
isitatshi:I-gel inokwakheka emanzini ashushu, i-hydrolyzed yi-enzymes kuqala kwi-dextrin, emva koko ibe yi-maltose, kwaye ekugqibeleni i-hydrolyzed ngokupheleleyo kwi-glucose. Kwizinto zokuthambisa, inokusetyenziswa njengenxalenyeyomgubo ekrwadaimathiriyeli kwiimveliso zomgubo wecosmetic kunye ne-adhesives kwi-rouge. kunye ne-thickeners.
xanthan gum:Inyibilika ngokulula kumanzi abandayo nakumanzi ashushu, inokumelana ne-ion, kwaye ine-pseudoplasticity. I-viscosity iyancitshiswa kodwa inokufunyanwa phantsi kokucheba. Ihlala isetyenziswa njenge-thickener kwiimaski zobuso, i-essences, iitoni kunye nezinye ii-agent zamanzi. Ulusu luziva lugudile kwaye luphepha ukusongelwa. I-ammonium preservatives isetyenziswa kunye.
Sclerotin:I-gel ye-100% yendalo, isisombululo se-scleroglucan sinozinzo olukhethekileyo kwiqondo lokushisa eliphezulu, lunokusebenza kakuhle kuluhlu olubanzi lwamaxabiso e-pH, kwaye lunokunyamezela okukhulu kwii-electrolyte ezahlukeneyo kwisisombululo. Inomgangatho ophezulu we-pseudoplasticity, kwaye i-viscosity yesisombululo ayitshintshi kakhulu ngokunyuka nokuwa kweqondo lokushisa. Inempembelelo ethile yokuthambisa kunye nokuziva kakuhle kwesikhumba, kwaye isoloko isetyenziswa kwiimaski zobuso kunye neempawu.
Gum Gum:Inyibilika ngokupheleleyo emanzini abandayo nashushu, kodwa ayinyibiliki kwioyile, igrisi, iihydrocarbons, iiketones kunye neeesters. Inokusasazwa kumanzi ashushu okanye abandayo ukwenza ulwelo lwe-viscous, i-viscosity ye-1% yesisombululo se-aqueous yi-3 ~ 5Pa · s, kwaye isisombululo ngokubanzi singenako ukungena.
sodium alginate:Xa i-pH = 6-9, i-viscosity izinzile, kwaye i-alginic acid inokwenza i-colloidal precipitation kunye ne-calcium ions, kunye ne-alginic acid gel inokugqithwa kwindawo ene-acidic.
carrageenan:I-Carrageenan inokumelana ne-ion elungileyo kwaye ayichanabekanga kukonakala kwe-enzymatic njengezinto eziphuma kwi-cellulose.
2. Semi-synthetic amanzi-enyibilikayo thickener
I-methylcellulose:MC, amanzi adumba abe yicolloidal ecacileyo okanye encinci ye-turbid solution. Ukunyibilikisa i-methylcellulose, qala uyisasaze kumlinganiselo othile wamanzi xa iphantsi kobushushu bejeli, uze wongeze amanzi abandayo.
Hydroxypropylmethylcellulose:I-HPMC yi-non-ionic thickener, ethi idumbe ibe yisisombululo esicacileyo okanye esincinci se-colloidal emanzini abandayo. Inesiphumo esihle sokunyusa amagwebu kunye nokuzinzisa kwinkqubo yokuhlamba ulwelo, iphucula ukuhambelana kwenkqubo, kwaye inefuthe le-synergistic kunye ne-cationic conditioners, iphucula ngokufanelekileyo ukusebenza kwe-Wet combing, i-alkali inokukhawulezisa izinga lokuchithwa kwayo, kwaye yandise kancinane i-viscosity, i-hydroxypropyl methylcellulose izinzile kwiityuwa eziqhelekileyo, kodwa xa ukuxinwa kwesisombululo setyuwa kuphezulu, i-viscosity ye-hydroxypropyl methylcellulose isisombululo iya kunciphisa ukuthambekela kokunyuka.
isitashi se-sodium carboxymethyl:CMC-Na, xa iqondo lokutshintsha lingaphezulu kwe-0.5, linyibilika ngokulula emanzini ukwenza i-colloid ebonakalayo; I-CMC eneqondo lokubeka endaweni engaphantsi kwe-0.5 ayinyibiliki emanzini, kodwa inokunyibilika kwisisombululo esimanzi sealkaline. I-CMC ihlala ikhona ngohlobo lweeaggregates ezininzi zeemolekyuli emanzini, kwaye i-viscosity iphezulu kakhulu. Njengoko iqondo lokushisa linyuka, i-viscosity iyancipha. Xa i-pH i-5-9, i-viscosity yesisombululo izinzile; xa i-pH ingaphantsi kwe-3, i-hydrolysis iyenzeka ngelixa imvula isenzeka; xa i-pH ingaphezu kwe-10, i-viscosity iyancipha kancane. I-viscosity yesisombululo se-CMC nayo iya kuncipha phantsi kwesenzo se-microorganisms. Ukuqaliswa kwe-calcium ions kwisisombululo samanzi se-CMC kuya kubangela i-turbidity, kwaye ukongezwa kwee-ion zetsimbi eziphezulu ezifana ne-Fe3 + kunye ne-Al3 + kunokubangela ukuba i-CMC ikhuphe okanye yenze i-gel. Ngokuqhelekileyo, intlama irhabaxa noko.
Iselulosi yeHydroxyethyl:I-HEC, i-thickener, i-arhente yokumisa. Inokubonelela nge-rheology elungileyo, ukwenza ifilimu kunye neempawu zokuthambisa. Uzinzo oluphezulu, imvakalelo yolusu encangathi kakhulu, ukuxhathisa okulungileyo kakhulu kwe-ion, kuyacetyiswa ngokubanzi ukuba ukusasazeke emanzini abandayo kwaye emva koko ubushushu kunye nokushukumisa ukunyibilika ngokulinganayo.
I-PEG-120 iMethyl Glucose Dioleate:Isetyenziswa ngokukhethekileyo njengento etyebisayo yeshampu, ijeli yeshawa, isicoci sobuso, isicoci sesandla, iimveliso zokuhlambela abantwana, kunye neshampu engakrazuli zinyembezi. Isebenza ngakumbi kwezinye ii-surfactants ekunzima ukuzijiya, kwaye i-PEG-120 methyl glucose dioleate ayicaphukisi emehlweni. Ilungele ishampu yomntwana kunye neemveliso zokucoca. Isetyenziswa kwiishampu, izicoci zobuso, i-AOS, ityuwa yesodium ye-AES, ityuwa ye-sulfosuccinate kunye ne-amphoteric surfactants esetyenziswa kwijeli yeshawari ineziphumo ezilungileyo zokudibanisa kunye nokutyeba.
