Hydroxypropyl methylcelluloseose mea fa'aaoga lautele. Aemaise i le faʻaaogaina o le paʻu putty. O loʻo i ai le tele o mea tau oloa e pei o le: masima tetee, gaioiga i luga, gelation vevela, faʻamautu PH, taofi vai, faʻapipiʻi, ma isi. Ae ui i lea, o le hydroxypropyl methylcellulose e faigofie foi i nisi o faafitauli. E tolu mafuaʻaga o faʻafitauli:

1. Le faʻaogaina o le hydroxypropyl methylcellulose

2, o le aofaʻi o mea faʻavae

3. O se tuufaatasiga talafeagai o fillers i le fua

Mo se faʻataʻitaʻiga, o le faʻataʻitaʻiga viscosity o le hydroxypropyl methylcellulose o loʻo faʻaaogaina le talafeagai, o le aofaʻi o mea faʻavae e tele naua, o le faʻamalieina o le faʻatumu e lelei tele, ma isi mea seʻia oʻo ina faia le faʻatonuga mo mafuaaga faʻapitoa, e pei o le faʻaoga saʻo o le hydroxypropyl methylcellulose ma se faʻataʻitaʻiga viscosity o le 100,000 Oloa, o le fua e le tatau ona itiiti ifo i le 3.5 kilokalama / tone, ma le fua ole polyvinyl paʻu. le ava malosi e le tatau ona tele naua, aua le maualuga atu i le 6%. O le faʻatumu lelei e masani ona faʻaaogaina le 325 mesh faʻatumu masani, ma pe a sili atu i le 600 mesh, o le faʻatinoga o le fausiaina o le a aʻafia leaga. Manatua o le tulaga o loʻo i luga e tatau ona foia ai le faʻafitauli o le leaga o le vaʻavaʻa.
