Hydroxyethyl Cellulose (HEC)
Hydroxyethyl Cellulose(HEC)
CAS:9004-62-0
Hydroxyethyl Cellulose(HEC) o le ether cellulose e le mafai ona solu i le vai, faʻaaogaina e pei o le mafiafia, colloid puipuia, vai faʻatumauina ma le rheology modifier i faʻaoga eseese e pei o vali vai, mea fau fale, suauʻu vailaʻau vailaʻau ma mea e tausia ai le tagata lava ia.
O le HEC o loʻo faʻapipiʻiina e ala i le tuʻuina atu o vaega o le hydroxyethyl (-CH₂CH₂OH) i totonu o le filifili polymer cellulose e ala i se tali etherification. O lenei suiga e faʻaleleia ai lona solubility vai, mafiafia gafatia, ma le fetaui ma faʻasologa eseese.

Tulaga Autu:
1. Fa'atumauina Suavai Lelei: Fesoasoani e taofia le fa'amamago vave i oloa fa'avae sima ma mea teuteu.
2. Fa'amautu i luga o le lautele o le pH: E tumau pea le aoga i si'osi'omaga acidic, neutral, ma alkaline.
3. Non-Ionic ma Fegalegaleai: E galue lelei i vailaʻau eseese, e aofia ai masima, surfactants, ma isi polymers.
4. Faʻaleleia le faʻatinoga o oloa: Faʻaleleia le mafiafia, faʻapipiʻi, faʻapipiʻi ata, ma mea emulsification.
5. Siosiomaga ma Biodegradable: E maua mai le cellulose, HEC e le oona ma biodegradable.
6. Improves Rheology and Flow Properties: Fa'ataga mo le viscosity pulea, puipuia fa'atete, sagging, ma vaega vavaeeseina.
afifiina:
HEC Oloa o loʻo faʻapipiʻiina i totonu o taga pepa e tolu faʻatasi ma totonu o le polyethylene ato faʻamalosia, mamafa mamafa e 25kg i le taga.
Teuina:
Taofi i totonu o faleteuoloa matutu malulu, mamao ese mai le susu, la, afi, timu.
KIMA Chemical Co., Ltd. o se tagata gaosi tomai faapitoa i le gaosiga o cellulose ethers, e aofia aiHydroxyethyl Cellulose(HEC). Faatasi ai ma le gaosiga gafatia o le 20,000 tone i le tausaga, KIMA Chemical e ofoina atu le tele o oloa HEC maualuga i lalo o le igoa KimaCell®, e tautuaina alamanuia eseese e pei o le fausiaina, vali ma ufiufi, vailaʻau, ma le tausiga o le tagata lava ia.
