Hydroxypropyl methyl cellulose ndi nonionic cellulose ether yomwe imapangidwa kuchokera thonje loyengeka kudzera machitidwe angapo a etherification. Ntchito yake yayikulu ndi iyi:
1. HPMC ndi ufa woyera kapena wachikasu pang'ono. wopanda fungo, wopanda poizoni
2. HPMC itha kusungunuka mwachangu m'madzi ozizira kuti ipange yankho lowoneka bwino;
3. Maso amtundu wa HPMC amadzimadzi amtundu wokhazikika mumtundu wa PH3.0-10.0. Mtengo wa PH ukakhala wochepera 3 kapena wopitilira 10, mawonekedwe am'maso adzachepetsedwa kwambiri
4. Njira yamchere ya HPMC ili ndi chochita chapamwamba, kotero kuti imasunthika ndikuteteza kukhazikika kwa colloid
5. Kugwiritsa ntchito kutsuka kwamadzi otentha ndikuyeretsa bwino panthawi yokonzekera kudapangitsa kuti pakhale phulusa lochepa
6. HPMC ndi hydrophilic, yowonjezera pamatope, gypsum, utoto ndi zinthu zina kuti zithe kugwira ntchito kwambiri
7. HPMC imakhala ndi kukana bwino komanso kusungunuka bwino kosungira kosakhalitsa
8. HPMC ingachepetse koyefishienti yolimbana ndikuthandizira kuyamwa kwa zomangamanga
9. HPMC imatha kupanga pepala lamphamvu komanso losavuta ndi mafuta abwino komanso kukana kwa ester

Kugwiritsa:
1. Khoma lamkati lamkati
Malo osungira madzi a HPMC amapanga ufa wa putty sungang'ambike chifukwa choumitsa mwachangu mutatha kumanga, kukulitsa mphamvu pambuyo pakuumitsa.Nthawi imodzimodziyo imathandizanso pakukweza mgwirizano
2. Makina akunja otchinga makina
Kuwonjezera kwa HPMC kungathandize kuti mgwirizano ukhale wolimba komanso kuti matope aziyenda bwino komanso kuti ntchito ziziyenda bwino
3. Mtondo wosakanikirana
HPMC kusungidwa bwino kwa madzi, kumatha kukhala ndi nthawi yayitali yomanga, kulepheretsa matayala achilengedwe kuti asatayire madzi msanga atha kugwa, kusintha mphamvu zamagetsi ndikumeta ubweya
4. Kupaka pulasitala pamiyala ndi zinthu
Kukaniza kupachikidwa kwa HPMC kumatha kuthetsa kugwedezeka kwa nyumba ndikugwiritsa ntchito zokutira zokulirapo
5. Kupaka pulasitala kwamakina
HPMC kusintha fluidity matope, magawowa mpope kutengerapo, kupewa matope stratification ndi chitoliro plugging
6. Chitsulo chosiyidwa (pepala lopepuka)
HPMC itha kukonza njira zomatira za gypsum pepala itatha, ikulimbitsa mgwirizano komanso mafuta, ndikutsimikiza
7. matope odziyimira pawokha
HPMC yocheperako imatha kuthana ndi mpweya ndipo imathandizira kutuluka kwa matope.Its yosungidwa ndi madzi amathandizira kusweka ndi shrinkage
Katemera / Mayendedwe
Zogulitsazo zimakulungidwa m'matumba opangidwa ndi polypropylene okhala ndi matumba amkati opaka pulasitiki, okhala ndi kulemera kwa 25kg pa thumba. Mverani mvula ndi dzuwa poteteza.
