Cellulose ethers o se vaega o polymers felagolagomai ma faʻaaogaina lautele e maua mai le cellulose, o se polysaccharide masani e maua i totonu o puipui o laau.O nei polymers o loʻo faʻaalia i le soluble vai, biodegradability, ma mea e fai ata tifaga.E ui o le cellulose ethers e leʻo faʻaogaina saʻo i le gaosiga o palasitika masani, latou te faia se sao taua i pisinisi eseese e pei o vailaʻau, meaʻai, fausiaina ma ie.
Cellulose Ethers: Va'aiga lautele
O le Cellulose o le polymer organic sili ona tele i luga o le lalolagi, ma o ana mea e maua mai ai, e taʻua o cellulose ethers, e faʻapipiʻiina e ala i le fesuiaiga o vailaʻau o molelaʻau cellulose.O puna masani o le cellulose e aofia ai le pulupulu laupapa, cotton, ma isi alava laau.
O le cellulose ethers autu e aofia ai:
Methylcellulose (MC): Faʻaaogaina e ala i le suia o vaega hydroxyl o cellulose ma vaega methyl, MC e faʻaaogaina lautele i le gaosiga o meaʻai, vailaʻau ma le fausiaina.Ua lauiloa ona o mea e teu ai le vai, ua avea ai ma mea faaopoopo lelei i le tele o talosaga.
Hydroxypropylcellulose (HPC): I lenei fa'atupu, o vaega hydroxyl o cellulose ua suia i vaega hydroxypropyl.E masani ona fa'aogaina le HPC i vaila'au, mea teuteu, ma mea tau tausiga a le tagata lava ia ona o ona mea e fai ai ata ma mafiafia.
Hydroxyethyl cellulose (HEC): E maua le HEC e ala i le tuʻuina atu o vaega hydroxyethyl ile cellulose.E faʻaaogaina e avea o se mafiafia, fusi ma faʻamautu i pisinisi e pei o mea faʻapipiʻi, vali ma mea tau tausiga a le tagata lava ia.
Carboxymethylcellulose (CMC): E maua le CMC e ala i le suia o vaega o le hydroxyl vaega i vaega carboxymethyl.E faʻaaogaina lautele i totonu o meaʻai meaʻai e pei o se mafiafia ma faʻamautu ma i totonu o falemaʻi vailaʻau mo ona mea faʻapipiʻi.
Fa'aaogāga ole cellulose ethers
1. Alamanuia tau taumafa:
Cellulose ethers, aemaise CMC, e masani ona faʻaaogaina i le gaosiga o meaʻai e faʻaleleia ai le tino, mautu ma le viscosity o oloa eseese e pei o asikulimi, salati salati ma mea tao tao.
2. Vailaau Fa'asaina:
Methylcellulose ma isi cellulose ethers o loʻo faʻaaogaina i vailaʻau faʻamaʻi e pei o fusi, faʻalavelave, ma mea e fai ata tifaga i le gaosiga o papa.
3. Alamanuia faufale:
HEC ma le MC e masani ona faʻaaogaina i le fale faufale e faʻaleleia ai le faʻatinoina o sima, faʻapipiʻi ma paʻu.Latou te fesoasoani i le faʻaleleia o galuega ma le taofiofia o le vai.
4. Mea tau tausiga a le tagata lava ia:
Hydroxypropyl cellulose ma le hydroxyethyl cellulose o loʻo maua i le tele o mea tau tausiga a le tagata lava ia e pei o shampoos, lotions ma mea teuteu, e maua ai le viscosity ma le mautu.
5. Ieie:
Cellulose ethers o loʻo faʻaaogaina i le lolomiina o ie ma le valiina o faiga ona o lo latou mafiafia ma faʻamautu meatotino.
O le cellulose ethers e tele fa'amanuiaga tau le siosiomaga:
Biodegradability:
E le pei o le tele o polymers synthetic, cellulose ethers e biodegradable, o lona uiga latou te malepelepe i faiga masani, faʻaitiitia ai lo latou aʻafiaga i le siosiomaga.
Malosiaga Fa'afouina:
O le Cellulose, o le mea mataʻutia mo cellulose ethers, e maua mai punaoa faʻafouina e pei o fafie ma alava laau.
Fa'aitiitia le fa'alagolago ile petrochemicals:
O le faʻaaogaina o cellulose ethers i le tele o talosaga e faʻaitiitia ai le faʻalagolago i polymers petrochemical ma fesoasoani i se auala e sili atu ona gafataulimaina.
Luitau ma faasinoga i le lumanai
E ui o le cellulose ethers e ofoina atu le tele o mea lelei, o loʻo i ai foi nisi o luʻitau, e pei o le faʻatapulaʻaina o le faʻamautuina o le vevela ma suiga faʻapitoa i meatotino e faʻavae i luga o le puna o le cellulose.O suʻesuʻega faʻaauau e taulaʻi i le faʻatalanoaina o nei luʻitau ma le suʻesuʻeina o faʻaoga fou o cellulose ethers i nofoaga faʻaalia.
O le cellulose ethers e maua mai i le tele o cellulose fa'afouina ma e iai sona sao taua i pisinisi eseese.E ui lava e le o ni palasitika faʻaleaganuʻu, o latou meatotino e saofagā i le atinaʻeina o oloa faʻalelei ma faʻagasologa.A'o fa'aauau pea ona sa'ilia e le aufaipisinisi ni auala fa'atumauina, o le cellulose ethers e foliga mai o le a tumau pea i luma o mea fou, fa'ateleina le alualu i luma i le tele o talosaga.
