Atina'e ole Rheological Thickener

O le atina'eina o mafiafia rheological ua avea ma fa'ailoga taua i le tala fa'asolopito o mea fa'asaienisi ma inisinia.Rheological thickeners o mea ia e mafai ona faʻateleina le viscosity ma / poʻo le pulea o le tafe o mea o vai, faʻamalolo, ma emulsions.

O le muamua rheological mafiafia na maua faʻafuaseʻi i le 19 senituri, ina ua tuʻu le faʻafefiloi o vai ma le falaoamata e tu mo se vaitaimi, ma maua ai se mea mafiafia, pei o se gel.O lenei paluga na maua mulimuli ane o se taofiga faigofie o fasi falaoamata i totonu o le vai, lea e mafai ona faʻaaogaina e avea o se mafiafia i faʻaoga eseese.

I le amataga o le senituri lona 20, na maua ai isi mea e mafiafia ai mea, e pei o masoa, pulumu, ma omea.O mea nei na fa'aaogaina e fai ma mafiafia rheological i le tele o fa'aoga, mai mea'ai ma mea teuteu i vali ma sua vai.

Ae ui i lea, o nei mea mafiafia faanatura e iai ni tapula'a, e pei o le fesuisuia'i o le faatinoga, ma'ale'ale i tulaga fa'agaioiga, ma le ono afaina ai microbiological.O lenei mea na mafua ai le atinaʻeina o mea faʻapipiʻi faʻamalo, pei ole cellulose ethers, polymers acrylic, ma polyurethanes.

Cellulose ethers, e pei o le sodium carboxymethyl cellulose (CMC), methyl cellulose (MC), ma le hydroxypropyl cellulose (HPC), ua avea ma se tasi o le sili ona faʻaaogaina rheological mafiafia i talosaga eseese, ona o latou meatotino tulaga ese, e pei o le solubility vai, pH mautu, lagona malosi o le ionic, ma le mafai ona fai ata.

O le atinaʻeina o mea faʻapipiʻi rheological mafiafia ua mafai ai ona faʻatulagaina oloa ma faʻatinoga faifaipea, faʻaleleia le mautu, ma faʻaleleia galuega.Fa'atasi ai ma le fa'atupula'ia o mana'oga mo meafaitino e maualuga le fa'atinoga, o le atina'eina o mafiafia fou o le rheological e fa'amoemoe e fa'aauau, fa'aosoina e ala i le aga'i i luma i mea fa'asaienisi, kemisi, ma inisinia.
