Numera CAS 9004-62-0 o le numera e iloagofie ai vaila'au ole Hydroxyethyl Cellulose (HEC). Hydroxyethyl Cellulose o se polymer non-ionic vai-soluble e masani ona faʻaaogaina i le tele o fale gaosi oloa ma oloa i aso uma faʻatasi ai ma le mafiafia, faʻamautu, faʻataʻitaʻiga ma mea faʻamamaina. O loʻo i ai le tele o faʻaoga, faʻapipiʻi faʻapipiʻi, fausiaina, meaʻai, vailaʻau, mea teuteu ma isi fanua.
1. Mea fa'avae ole Hydroxyethyl Cellulose
Fuafuaga mole: Faʻalagolago i lona tikeri o le polymerization, o se mea e maua mai i le cellulose;
Numera CAS: 9004-62-0;
Fa'aaliga: Hydroxyethyl Cellulose e masani ona aliali mai i foliga o le pa'epa'e pa'epa'e po'o le lanu samasama, e leai se manogi ma le tofo;
Solubility: HEC e mafai ona faʻamavaeina i le malulu ma le vai vevela, e lelei le solubility ma le mautu, ma fausia ai se fofo manino pe translucent pe a uma ona faʻamavae.
Sauniuniga ole Hydroxyethyl Cellulose
O le Hydroxyethyl Cellulose e saunia e ala i le fa'aogaina o le cellulose ma le ethylene oxide. I lenei faagasologa, e tali atu le ethylene oxide ma le vaega hydroxyl o le cellulose e ala i se tali etherification e maua ai le cellulose hydroxyethylated. E ala i le fetuutuunai o tulaga o le tali atu, e mafai ona pulea le tikeri o le hydroxyethyl substitution, lea e fetuunai ai le solubility vai, viscosity ma isi mea faaletino o le HEC.
2. Fa'aletino ma kemisi o le hydroxyethyl cellulose
Viscosity tulafono faatonutonu: Hydroxyethyl cellulose o se mafiafia lelei ma e masani ona faaaoga e fetuunai le viscosity o vai. O lona fofo viscosity e faalagolago i le solubility concentration, tikeri o le polymerization ma le tikeri o le suitulaga, o lea e mafai ai ona pulea ona meatotino rheological e ala i le fetuunaiga o le mamafa mole;
Gaoioiga i luga ole laiga: Talu ai o molelaʻau HEC o loʻo i ai se numera tele o vaega hydroxyl, e mafai ona latou faia se ata mole mole i luga o le atinaʻe, taʻalo le matafaioi o se surfactant, ma fesoasoani e faʻamautu emulsions ma faiga faʻamalolo;
Ata-fausia meatotino: Hydroxyethyl cellulose e mafai ona fausia se ata toniga pe a uma ona mago, o lea e masani ona faʻaaogaina i mea teuteu, vailaʻau vailaʻau ma isi fanua;
Faʻamauina o le susu: O le hydroxyethyl cellulose e lelei le faʻamamaina, e mafai ona faʻafefe ma taofi le susu, ma fesoasoani e faʻalautele le taimi susu o le oloa.
3. Fa'aoga vaega
Faʻapipiʻi ma mea faufale: HEC o se mea faʻapipiʻi masani ma faʻamautu i totonu o pisinisi faʻapipiʻi. E mafai ona faʻaleleia atili le rheology o le faʻapipiʻiina, faʻapipiʻi atili le toniga, ma aloese mai le sagging. I mea faufale, e faʻaaogaina i le sima sima, gypsum, putty paʻu, ma isi mea, e faʻaleleia ai le faʻatinoga o le fausiaina, faʻaleleia le taofiofia o le vai ma faʻaleleia le teteʻe.
Kemikolo i aso uma: I mea teuteu ma mea e tausia ai le tagata lava ia, e masani ona faʻaaogaina le HEC i le shampoo, gel taʻele, lotion ma isi oloa e tuʻuina atu ai le mafiafia ma le faʻamautu faʻamautu, aʻo faʻaleleia le malosi o le susu.
Alamanuia mea'ai: E ui e seasea fa'aogaina le HEC i mea'ai, e mafai ona fa'aogaina e fai ma mafiafia ma fa'amautu i nisi o mea'ai fa'apitoa e pei ole aisakulimi ma fa'amamafa.
Fomaʻi faʻafomaʻi: HEC e masani ona faʻaaogaina e avea o se mafiafia ma se matrix mo capsules i vailaʻau vailaʻau, aemaise lava i vailaʻau ophthalmic mo le gaosiga o loimata faʻapitoa.
Alamanuia pepa: E fa'aaogaina le HEC e fai ma fa'asili pepa, fa'alelei luga ma fa'apipi'i fa'apipi'i i totonu o le pisinisi fai pepa.
4. Tulaga lelei o le hydroxyethyl cellulose
Lelei solubility: HEC e faigofie ona solu i le vai ma e mafai ona vave fausia se vaifofo viscous.
Fetuuna'i fa'aoga lautele: E talafeagai le HEC mo le tele o ala o faasalalauga ma siosiomaga pH.
Lelei mautu kemisi: HEC e matua mautu i le tele o solvents ma vevela ma mafai ona faatumauina ana galuega mo se taimi umi.
5. Soifua Maloloina ma le saogalemu ole hydroxyethyl cellulose
Hydroxyethyl cellulose e masani ona manatu o se mea e le afaina i le tino o le tagata. E le oona ma e le afaina ai le paʻu poʻo mata, o lea e faʻaaogaina lautele i mea teuteu ma vailaʻau. I le si'osi'omaga, HEC e lelei fo'i le biodegradability ma e le mafua ai le fa'aleagaina o le si'osi'omaga.
Hydroxyethyl cellulose o loʻo faʻatusalia e le CAS Numera 9004-62-0 o se mea polymer multifunctional ma faʻatinoga sili ona lelei. Ona o lona mafiafia, faʻamautu, ata-fausia, susu ma isi mea totino, e faʻaaogaina lautele i vaega eseese o gaosiga o pisinisi ma le olaga i aso uma.
