Taulai atu i ethers Cellulose

Cellulose Ethers mai Kima Co. vailaau, Ltd

Ethers Cellulose  o vai-soluble polymers maua mai cellulose, o le polymer sili ona tele i le natura. Mo le silia ma le 60 tausaga, o nei oloa vavai na avea ma se matafaioi taua i le tele o talosaga, mai oloa fausia, ceramics ma paints i meaai, cosmetics ma vailaau.
Mo oloa fausia, ethers cellulose galue e avea thickeners, ni faila, ata tifaga formers ma sooupu vai-faatumauina. Latou foi faagaoioia o fesoasoani e taofia lē tumau, surfactants, lubricants, colloids ma emulsifers puipui. I le faaopoopo atu, fofo aqueous o ethers nisi cellulose thermally gel, o se meatotino tulaga ese e taalo i se matafaioi autu i se ofo
eseese o talosaga. E le o maua lenei tuufaatasiga taua o le meatotino i so o se isi polymer vai-soluble.
Le mea moni o le tele o meatotino aoga o le taimi e tasi le taimi nei ma galue masani i tuufaatasiga e mafai ona avea o se faamanuiaga o le tamaoaiga signifcant. I le tele o talosaga, lua, tolu pe sili atu mea e manaomia o le a manaomia e faia le galuega lava lea e tasi e faia e se tasi oloa Eteru cellulose. I le faaopoopo, e maualuga effcient ethers cellulose, e masani ona
tuuina atu o le faatinoga silisili ona lelei i se faasalaga i lalo nai lo le manaomia ma isi polymers vai-soluble.
Ofoina vailaau Dow Fausiaina se autau tele o oloa cellulosic, e aofia ai methyl cellulose, cellulose hydroxyethyl ma cellulose carboxymethyl. Ethers cellulose Methyl ua sili ona lautele faaaogaina mo le tele o talosaga i le fale ma le fausiaina alamanuia.

Kemisi o Ethers Cellulose

Ofoina ethers cellulose tatou pisinisi i totonu o ituaiga autu e fa:
cellulose methyl 1.Hydroxyethyl (HEMC / MHEC)
cellulose methyl 2.Hydroxypropyl (HPMC, MC)

cellulose 3.Hydroxyethyl (HEC)

Cellulose methyl 4.Carboxy (CMC)
O ituaiga maua le ivitu polymeric o cellulose, o se carbohydrate masani o loo i ai se fausaga toe faavae o iunite anhydroglucose. I le taimi o le gaosia o ethers cellulose, cellulose alava e faamafanafana ma se tali caustic e faapea, i le faasologa, e tausia ma le methyl chloride, ma pe propylene oxide po oxide ethylene, e lolo atu hydroxypropyl methyl cellulose po hydroxyethyl methyl cellulose, faasologa. Le oloa tali fibrous o faamamaina ma le eleele i se sala tupe, efuefu toniga.
Ua tuufaatasia foi ua oloa vasega faapitoa e faamalieina ai manaoga o alamanuia specifc.
O loo maua lo tatou cellulose oloa Eteru i ituaiga eseese se tolu: efuefu, efuefu faia-luga ma granular. O le ituaiga o oloa ua tuufaatasia i uences fl lea fausia e filifili. I le tele o talosaga fefiloi-matutu, ua masani faaaogaina efuefu untreated, ae mo talosaga fefiloi-ua saunia, lea ua faaopoopo le efuefu cellulosic tonu i le vai, ua sili luga-faatatauina pauta po o faatulagaga granular.

Meatotino Aoao

Meatotino Aoao masani i lo tatou ethers cellulose loo lisiina atu iinei. Tagata oloa faaalia nei meatotino e eseese tikeri ma e mafai ona maua
meatotino faaopoopo manaomia mo talosaga faapitoa. Mo nisi faamatalaga, imeli i sales@kimachemical.com.
