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 teteʻe, galuega i luga, gelation vevela, faʻamautu PH, taofi vai, adhesion, 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 tu'ufa'atasiga talafeagai o fa'atumu i le fua fa'atatau
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 faʻaogaina saʻo o le hydroxypropyl methylcellulose ma se faʻataʻitaʻiga viscosity o le 100,000 Oloa, o le fua e le tatau ona laʻititi ifo i le 3.5 kilokalama / tone, ma o le vailaʻau o le polyvinyl alcohol e le tatau ona tele tele, e le sili atu i le 6%.E masani ona faʻaaogaina e le faʻatumu lelei le 325 mesh faʻatumu masani, ma pe a sili atu i le 600 mesh, o le faʻatinoga o le fausiaina o le a faʻaleagaina.Manatua o le tulaga o loʻo i luga e tatau ona foia ai le faʻafitauli o le leaga o le vaʻavaʻa.
