Putty powders e faʻaaogaina lautele i galuega faufale ma faʻafouina mo le toe faʻaleleia o taʻe, faʻatumu pu, ma faʻalelei luga.Cellulose ethers e masani ona faʻaaogaina e fai ma fusi i paʻu putty ona o lo latou gafatia e faʻaleleia ai le galue, faʻapipiʻi, ma le taofiofia o vai.Ae ui i lea, o le filifilia o le cellulose ethers saʻo mo paʻu putty e mafai ona luʻitau ona o le tele o filifiliga eseese o loʻo maua i le maketi.I totonu o lenei tusiga, o le a tatou talanoaina pe faʻapefea ona filifili le cellulose ethers saʻo mo paʻu putty.

O le a le Cellulose Ethers?

Cellulose ethers o se aiga o polymers e maua mai le cellulose, o se polymer masani e maua i laau.E solu vai ma e sili ona lelei e fai ata tifaga, lea e avea ai i latou ma mea fa'apipi'i lelei mo pa'u putty.E tele ituaiga o cellulose ethers o loʻo maua, e taʻitasi ma ona uiga faʻapitoa ma faʻamanuiaga.

Ituaiga Cellulose Ethers

Hydroxypropyl methyl cellulose o se ether cellulose ua suia lea e masani ona faʻaaogaina i paʻu putty ona o lona faʻapipiʻi lelei.E mafai fo'i ona fa'aleleia atili le fa'atumauina o le vai ma le fa'aogaina o pauta putty, fa'afaigofie ona fa'aoga ma fa'asalalauina.O le HPMC e tetee foi i le tuputupu aʻe o siama ma e lelei le mautu o le vevela.

3. Hydroxyethyl Cellulose (HEC)

O le hydroxyethyl cellulose o se ether cellulose non-ionic lea e masani ona faʻaaogaina i paʻu putty ona o ona mea sili ona mafiafia.E mafai fo'i ona fa'aleleia atili le fa'atumauina o le vai ma le fa'aogaina o pauta putty, fa'afaigofie ona fa'aoga ma fa'asalalauina.O le HEC e tete'e foi i le tuputupu a'e o siama ma e lelei le mautu o le vevela.

4. Carboxymethyl Cellulose (CMC)

Carboxymethyl cellulose o se ether cellulose ua suia lea e masani ona faʻaaogaina i paʻu putty ona o lona lelei tele o le taofiofia o vai.E mafai foʻi ona faʻaleleia le faʻaogaina o paʻu putty, faʻafaigofie ona faʻaoga ma salalau.O le CMC e tete'e foi i le tuputupu a'e o siama ma e lelei le mautu o le vevela.

Filifilia Sa'o Cellulose Ethers mo Putty Powders

A filifilia sa'o cellulose ethers mo putty powders, e tele mea e tatau ona e mafaufau i ai.E aofia ai:

1. Metotia Fa'aaogā

O le auala faʻaoga o le a e faʻaaogaina mo le putty powder o le a fuafua ai le ituaiga cellulose ether e tatau ona e faʻaogaina.Mo se faʻataʻitaʻiga, afai o le a e fufuluina le paʻu o le putty, e tatau ona e faʻaogaina se cellulose ether o loʻo i ai mea lelei e taofi ai le vai, e pei o le methyl cellulose.Afai o le a e togiina le paʻu putty, e tatau ona e faʻaogaina se cellulose ether o loʻo i ai mea faʻapipiʻi sili ona lelei, pei ole HPMC.

2. Ituaiga o Lafoa'i

O le ituaiga o mea e te fa'aogaina ai le pa'u pa'u o le a iloa ai fo'i le ituaiga cellulose ether e tatau ona e fa'aogaina.Mo se faʻataʻitaʻiga, afai o le ae faʻaogaina le paʻu paʻu i se mea faʻapipiʻi porous, e pei o le sima poʻo le faʻamaʻi, ona tatau lea ona e faʻaogaina se cellulose ether e sili ona lelei le taofiofia o vai, e pei o le methyl cellulose.Afai o le ae fa'aogaina le pa'u pa'u i se mea e le porous, e pei o le u'amea po'o le tioata, ona tatau lea ona e fa'aogaina le cellulose ether o lo'o i ai mea fa'apipi'i lelei, pei ole HPMC.

3. Meatotino Manaomia

O mea mana'omia o le putty powder o le a iloa ai foi le ituaiga cellulose ether e tatau ona e fa'aogaina.Mo se faʻataʻitaʻiga, afai e te manaʻo i le paʻu o le putty e iai ni mea e sili ona lelei e taofi ai le vai, ona tatau lea ona e faʻaogaina se cellulose ether o loʻo i ai mea e sili ona lelei e taofi ai le vai, e pei o le methyl cellulose.Afai e te manaʻo i le paʻu o le putty e iai ni mea faʻapipiʻi sili ona lelei, ona tatau lea ona e faʻaogaina se cellulose ether o loʻo i ai mea faʻapipiʻi lelei, pei ole HPMC.

4. Tulaga Siosiomaga

O tulaga o le siosiomaga lea o le a faʻaaogaina ai le paʻu putty o le a iloa ai foi le ituaiga cellulose ether e tatau ona e faʻaaogaina.Mo se faʻataʻitaʻiga, afai o le paʻu putty o le a faʻaaogaina i totonu o se siosiomaga susu, e tatau ona e faʻaogaina se cellulose ether e faʻasaʻo i le tuputupu aʻe o siama, e pei o le methyl cellulose poʻo le HPMC.Afai o le a faʻaaogaina le paʻu paʻu i totonu o se siosiomaga vevela, ona tatau lea ona e faʻaogaina se cellulose ether o loʻo i ai le faʻamautuina lelei o le vevela, e pei ole HEC poʻo le CMC.

Fa'ai'uga

Filifilia sa'o cellulose ethers mo putty powders e taua tele i le ausiaina o meatotino mana'omia ma le faatinoga o le oloa.Pe a filifilia le cellulose ether saʻo, e tatau ona e mafaufau i mea taua e pei o le faʻaogaina o le auala, ituaiga o mea faʻapipiʻi, mea manaʻomia, ma tulaga tau le siosiomaga.E ala i le filifilia o le cellulose ether talafeagai, e mafai ona e faʻamautinoa o lau paʻu putty e sili ona lelei le galue, faʻapipiʻi, ma mea e teu ai le vai, e faʻalelei ai mo le toe faʻaleleia o taʻe, faʻatumu pu, ma faʻalelei luga i le fausiaina ma le toe faʻaleleia o galuega.
