I-Hydroxyethyl cellulose (HEC) yintsika emhlophe okanye ekhaphukhaphu etyheli, engenavumba, engeyotyhefu okanye eqinileyo eyimpuphu elungiswe yi-etherification ye-alkaline cellulose kunye ne-ethylene oxide (okanye i-chlorohydrin). I-Nonionic e-soluble cellulose ethers. Ngenxa yokuba i-HEC ineepropati ezintle ezifana nokuqina, ukumisa, ukusabalalisa, i-emulsifying, i-bonding, i-film-forming, ukukhusela umswakama kunye nokubonelela nge-colloids ekhuselayo, isetyenziswe ngokubanzi ekunyamekelweni kwesikhumba, ukuhlola ioli, ukugubungela, ukwakhiwa, amayeza kunye nokutya, iingubo, ukwenza iphepha kunye neepolima. Polymerization kunye nezinye iinkalo. I-40 ye-mesh sieving rate ≥ 99%;
Iimpawu zenkangeleko: Ifibrous emhlophe ukuya kokukhanya emthubi okanye engumgubo eqinileyo, ayinatyhefu, ayinavumba, inyibilika lula emanzini. Ukunganyibiliki kwizinyibilikisi zendalo jikelele.
Iselulosi yeHydroxyethyl
Kuluhlu lwexabiso le-PH ye-2-12, utshintsho lwe-viscosity luncinci, kodwa i-viscosity iyancipha ngaphaya kolu luhlu. Uneempawu zokuqina, ukumisa, ukudibanisa, i-emulsifying, ukusabalalisa, ukugcina umswakama kunye nokukhusela i-colloid. Izisombululo zeendlela ezahlukeneyo ze-viscosity zinokulungiswa. Ayizinzanga phantsi kobushushu obuqhelekileyo kunye noxinzelelo, ukuphepha ukufuma, ubushushu kunye nobushushu obuphezulu, kwaye inokunyibilika kwetyuwa ngokugqwesileyo kwi-dielectrics, kwaye isisombululo sayo samanzi sivunyelwe ukuba siqulathe ukugcwala okuphezulu kweetyuwa kwaye izinzile.
Iipropati ezibalulekileyo: Njenge-surfactant engeyiyo i-ionic, i-hydroxyethyl cellulose inezi mpawu zilandelayo ngaphezu kokuqina, ukuxhoma, ukubopha, ukujikeleza, ukwenza ifilimu, ukusabalalisa, ukugcinwa kwamanzi kunye nokubonelela ngee-colloids ezikhuselayo:
1. I-HEC iyancibilika kumanzi ashushu okanye abandayo, kwaye ayigqithisi kwiqondo lokushisa eliphezulu okanye ukubilisa, okwenza ibe neentlobo ezininzi ze-solubility kunye neempawu ze-viscosity, kunye ne-gelation engeyiyo i-thermal;
2. Akuyiyo i-ionic kwaye inokubambisana kunye noluhlu olubanzi lwezinye iipolymers ezinyibilikayo zamanzi, i-surfactants kunye neetyuwa, kwaye i-colloidal thickener egqwesileyo equlethe i-high-concentration electrolyte solutions;
3. Umthamo wokugcinwa kwamanzi uphindwe kabini kunalowo we-methyl cellulose, kwaye unolawulo olungcono lokuhamba.
4. Xa kuthelekiswa ne-methyl cellulose eyaziwayo kunye ne-hydroxypropyl methyl cellulose, ikhono lokusabalalisa i-HEC libi kakhulu, kodwa i-colloid ekhuselayo inamandla amakhulu.

Indlela yokugoba
Joyina ngokuthe ngqo kwimveliso
1. Yongeza amanzi acocekileyo kwibhakethi enkulu ene-mixer ephezulu yokucheba.
2. Qala ukuvuselela ngokuqhubekayo ngesantya esiphantsi kwaye ucofe i-hydroxyethyl cellulose kwisisombululo ngokulinganayo.
3. Qhubeka uvuselela de onke amasuntswana afakwe emanzini.
4. Emva koko yongeza i-agent ye-antifungal, izongezo ze-alkaline ezifana ne-pigments, i-dispersing aids, amanzi e-ammonia.
5. Gxuma de kube yonke i-cellulose ye-hydroxyethyl ichithwe ngokupheleleyo (i-viscosity yesisombululo iyanda kakhulu) ngaphambi kokuba ungeze ezinye izinto kwifomula, kwaye ugaye de kube yimveliso egqityiweyo.
Indima ye-hydroxyethyl cellulose kwi-chemical composition of cosmetics? Iikhompawundi zepolymer ezinyibilikayo emanzini ezisetyenziswa kwizithambiso zohlulwe ikakhulu zibe ziindidi ezimbini: ezendalo kunye nezokwenziwa.
Iikhompawundi ze-polymer zendalo ezinyibilikayo zamanzi zibandakanya: isitashi, i-gum yezityalo, i-gelatin yezilwanyana, njl., Kodwa umgangatho awuzinzile, uchaphazeleka lula yimozulu, indawo yendawo, isivuno esilinganiselweyo, kunye nokuwohloka ngokulula ngamabhaktheriya kunye nokungunda.
I-synthetic water-soluble polymer compounds ziquka i-polyvinyl alcohol, i-polyvinylpyrrolidone, njl., Ezinezakhiwo ezizinzileyo, ukucaphuka kwesikhumba esincinci kunye nexabiso eliphantsi, ngoko ke zithathe indawo yendalo ye-polymer e-soluble yamanzi kwaye ibe ngumthombo oyintloko we-colloid ekrwada.
Iphinde yohlulwe ibe yi-semi-synthetic kunye ne-synthetic yeekhompawundi zepolymer ezinyibilikayo emanzini.
I-semi-synthetic yamanzi e-soluble polymer compounds idla ngokusetyenziswa: i-methyl cellulose, i-ethyl cellulose, i-sodium carboxymethyl cellulose, i-hydroxyethyl cellulose, kunye ne-guar gum kunye ne-derivatives yayo.
Iikhompawundi zepolymer ezinyibilikayo zamanzi zisetyenziswa ngokuqhelekileyo: i-polyvinyl alcohol, i-polyvinylpyrrolidone, i-acrylic acid polymer, njl.
Ezi zisetyenziswa kwizinto zokuthambisa njengezinto zokuncamathelisa, izinto ezityebisayo, iifilim, kunye nezizinzisi zeemulsion.
