01 Thickener
thickener:Mushure mekunyungudutswa kana kuparadzirwa mumvura, inogona kuwedzera viscosity yemvura uye kuchengetedza yakagadzikana yakagadzikana hydrophilic polymer compound muhurongwa. Iyo molecular chimiro ine akawanda hydrophilic mapoka, akadai -0H, -NH2, -C00H, -COO, nezvimwewo, iyo inogona hydrate nemamorekuru emvura kuti iite yakakwirira-viscosity macromolecular solution. Thickeners inoita basa rakakosha muzvizoro , nekukora, emulsifying, kumisa, kudzikamisa uye mamwe mabasa.
02 Thickener chiito musimboti
Sezvo mapoka anoshanda ari papolymer cheni kazhinji asiri ega, iyo yekukora nzira inowanzova yekuti imwe gobvu ine akati wandei maitiro ekukora.
Chain winding thickening: Mushure mekunge polymer yaiswa musolvent, cheni dzepolymer dzinopetwa uye dzakapinzwana. Panguva ino, viscosity yemhinduro inowedzera. Mushure me neutralization nealkali kana organic amine, iyo yakaipa charge ine yakasimba solubility yemvura, iyo inoita kuti polymer cheni ive nyore kuwedzera, nekudaro kuwana kuwedzera kwe viscosity. .
Covalently cross-linked thickening:Covalent crosslinking ndiko kuisirwa nguva nenguva kwebifunctional monomers iyo inogona kuita nengetani mbiri dzepolymer, kubatanidza mapolymers maviri pamwechete, kushandura zvakanyanya zvimiro zvepolymer, uye kuve nekumwe kumiswa kwekugona mushure mekunyungudika mumvura.
Kudyidzana kukora: Iyo imhando ye hydrophobic-inonyungudika mvura polymer, ine hunhu hwemhando ye surfactant. Iko kusanganiswa kwepolymer mumvura kunowedzera kushamwaridzana pakati pemamorekuru, uye kunopindirana neboka rehydrophobic repolymer pamberi peiyo surfactant, zvichiita kuti pave nepamusoro-soro inoshanda Musanganiswa micelles yeagent uye mapolymer hydrophobic mapoka, nokudaro kuwedzera mhinduro viscosity.
03Kurongwa kwezvikobvu
Zvinoenderana nekunyungudika kwemvura, inogona kukamurwa kuita: mvura-inonyungudika thickener uye micropowder thickener. Zvinoenderana neiyo thickener sosi inogona kukamurwa kuita: natural thickener, synthetic thickener. Maererano nekushandiswa, inogona kukamurwa kuva: mvura-based thickener, mafuta-based thickener, acidic thickener, alkaline thickener.

04Common thickeners
1. Natural mvura-soluble thickener
starch:Gel inogona kuumbwa mumvura inopisa, hydrolyzed nema enzymes kutanga mu dextrin, ipapo mu maltose, uye pakupedzisira yakazara hydrolyzed muglucose. Muzvizoro, inogona kushandiswa sechikamuyehupfu mbishizvinhu mucosmetic poda zvigadzirwa uye zvinonamira mu rouge. uye thickeners.
xanthan chingamu:Inonyungudika zviri nyore mumvura inotonhora nemvura inopisa, ine ion resistance, uye ine pseudoplasticity. Iyo viscosity yakaderedzwa asi inodzoreredzwa pasi pekuveura. Inowanzoshandiswa seyakakora mumasikisi echiso, essences, toners uye mamwe majenti emvura. Ganda rinonzwa rakatsetseka uye rinodzivisa kurunga. Ammonium preservatives inoshandiswa pamwe chete.
Sclerotin:100% natural gel, mhinduro ye scleroglucan ine kugadzikana kwakakosha pakupisa kwepamusoro, ine kushanda kwakanaka muhuwandu hwakawanda hwepH kukosha, uye ine kushivirira kukuru kune akasiyana ma electrolyte mumhinduro. Iyo ine dhigirii yakakwira yepseudoplasticity, uye viscosity yemhinduro haichinji zvakanyanya nekukwira nekudonha kwekushisa. Iine humwe hunyoro hunoita uye kunzwa kwakanaka kweganda, uye inowanzoshandiswa mumasiki echiso uye essences.
Guar Gum:Iyo inonyungudika zvachose mumvura inotonhora uye inopisa, asi isinganyungudika mumafuta, girisi, mahydrocarbon, ketoni uye esters. Inogona kuparadzirwa mumvura inopisa kana inotonhora kuita viscous liquid, viscosity ye 1% aqueous solution i 3 ~ 5Pa · s, uye mhinduro yacho haigoni kunyura.
sodium alginate:Kana pH = 6-9, viscosity yakagadzikana, uye alginic acid inogona kuumba colloidal precipitation ne calcium ions, uye alginic acid gel inogona kuderedzwa munzvimbo ine acidic.
carrageenan:Carrageenan ine yakanaka ion kuramba uye haikonzereki nekuora enzymatic sezvinobva mu cellulose.
2. Semi-synthetic mvura-soluble thickener
Methylcellulose:MC, mvura inoputika kuita yakajeka kana zvishoma turbid colloidal solution. Kuti uparadze methylcellulose, tanga waiparadzira mune imwe huwandu hwemvura kana yakadzikira pane tembiricha yegel, wobva wawedzera mvura inotonhora.
Hydroxypropylmethylcellulose:HPMC isiri-ionic thickener, iyo inoputika kuva yakajeka kana zvishoma turbid colloidal solution mumvura inotonhora. Iyo ine yakanaka furo-inowedzera uye inodzikamisa mhedzisiro mune yemvura yekuwachisa sisitimu, inovandudza kuenderana kweiyo sisitimu, uye ine synergistic mhedzisiro ine cationic conditioners, zvinobudirira kuvandudza Wet combing kuita, alkali inogona kukurumidzira kuparara kwayo, uye kuwedzera zvishoma viscosity, hydroxypropyl methylcellulose yakagadzikana kune yakawanda munyu, asi kana kusanganiswa kwemunyu munyu kwakakwira, viscosity yehydroxypropyl methylcellulose mhinduro inoderedza tsika yekuwedzera.
Sodium carboxymethyl starch:CMC-Na, kana dhigirii rekutsiva rakakura kupfuura 0.5, inonyungudika zviri nyore mumvura kuita colloid inoonekera; CMC ine dhigirii yekutsiva yakaderera pane 0.5 hainyungudika mumvura, asi inogona kunyungudika muine alkaline aqueous solution. CMC inowanzovapo muchimiro chema molecular aggregates mumvura, uye viscosity yakakwirira kwazvo. Sezvo tembiricha inowedzera, viscosity inoderera. Apo pH iri 5-9, viscosity yemhinduro yakagadzikana; apo pH iri pasi pe3, hydrolysis inoitika apo kunaya kunoitika; apo pH yakakura kudarika 10, viscosity inoderera zvishoma. Iyo viscosity yeCMC mhinduro ichadzikirawo pasi pekuita kwema microorganisms. Kuiswa kwe calcium ions muCMC aqueous solution kuchakonzera turbidity, uye kuwedzerwa kwe-high-valent metal ions yakadai seFe3+ neAl3+ inogona kukonzera CMC kudonha kana kuumba gel. Kazhinji, paste yacho inenge yakaoma.
Hydroxyethyl cellulose:HEC, thickener, kumisa mumiririri. Inogona kupa yakanaka rheology, firimu-kugadzira uye moisturizing zvivakwa. Kugadzikana kwepamusoro, kunzwa kweganda rakanamira, yakanaka kwazvo ion kuramba, inowanzokurudzirwa kupararira mumvura inotonhora uye wozopisa nekuzunguza kunyungudika zvine homogeneous.
PEG-120 Methyl Glucose Dioleate:Inonyanya kushandiswa seyakakora ye shampoo, gel yekugeza, yekuchenesa kumeso, sanitizer yemaoko, zvigadzirwa zvekugezesa zvevana, uye shampoo isina kubvarura. Inonyanya kushanda kune mamwe ma surfactants akaoma kukora, uye PEG-120 methyl glucose dioleate haisi kutsamwisa maziso. Yakanakira shampoo yemwana uye zvigadzirwa zvekuchenesa. Inoshandiswa mumashampoos, kuchenesa kumeso, Iyo AOS, AES sodium munyu, sulfosuccinate munyu uye amphoteric surfactants inoshandiswa mugeri yekugezera ine yakanaka kusanganisa uye kukora mhedzisiro.
