Hydroxypylferose (HPMC) ndi yowonjezera kwambiri yomwe imagwiritsidwa ntchito kwambiri pomanga zida zomangira, makamaka popanga maphala ndi ziphuphu. HPMC ndi ma cellulose, osungunuka am'madzi opangidwa ndi magazi opangidwa ndi ma cellulose omwe amasinthidwa mwanjira yachilengedwe. Imakhala ndi zipatso zabwino kwambiri, kusungidwa kwamadzi, mafuta opangira mafilimu, omwe amagwira ntchito yofunika kwambiri pokonza ntchito, makina ndi kulimba kwa maphala ndi ma punya.
1. Kukonzanso magwiridwe antchito a madzi
Chimodzi mwazovuta za HPMC ndi katundu wake wabwino kwambiri. Mu maboti ndi ziphuphu, hpmc imachepetsa kwambiri kuchuluka kwa madzi amatuluka, kuyambira nthawi yotseguka mabowo ndi ma punya. Katunduyu ndi wofunikira kwambiri pantchito yomanga chifukwa imatsimikizira kuti matope ndi mazira amatenga nthawi yokwanira nthawi yochepa pakagona, kupewa kusokonekera komanso kubisidwa kosavuta chifukwa choyanika koyambirira. Kuphatikiza apo, kubwezeretsa kwamadzi kumakopa zinthu zabwino kwambiri za simenti, potero kukuwonjezera kulimba kwambiri madope ndi ziphuphu.
2. Kukonzanso ntchito zomanga
HPMC imathandiza kwambiri kugwirira ntchito maboti ndi ziphuphu. Chifukwa cha kukula kwake, HPMC imatha kuwonjezera matope a matope, ndikupangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikugwiritsa ntchito. Izi ndizofunikira makamaka kukhoma ndi kumanga kwa denga, monga HPMC imapangitsa matope ndi mapiko ambiri osalimbana ndi kukangana. Kuphatikiza apo, kupatsidwa mafuta kwa hpmc kumatha kusintha madzima matope ndikugawana nawo zida zomangira zomangira, potengera luso la ntchito yomanga ndi mawonekedwe ake.
3. Kuchulukitsa Kutsatira
HPMC imasintha chitsamba cha mankhusu ndi ziphuphu, makamaka pamagawo a avorganic monga njerwa, konkriti ndi miyala. HPMC imasintha mphamvu ya zinthu zozikidwa ndi simenti powonjezera kuchuluka kwa madzi osungitsa madzi a matope ndikuwonjezera nthawi ya simenti. Nthawi yomweyo, kanemayo wopangidwa ndi HPMC akhoza kukulitsa mphamvu yolumikizirana pakati pa matope ndi zinthu zam'munsi, kupewa matope kuchokera kugwa kapena kusweka.
4. Sinthani kukana kukana
Kuonjezera HPMC kwa matope ndi ma pulasitiki amatha kusintha mkwiyo wawo. Chifukwa cha kusungidwa kwamphamvu kwamadzi komanso kukula kwamphamvu kwa HPMC, matope amatha kukhala onyowa kwa nthawi yayitali nthawi yowuma, kuchepetsa mafilimu shrinkage komanso madzi owuma oyambitsidwa ndi kutaya kwamadzi kwambiri. Kuphatikiza apo, kapangidwe kabwino kopangidwa ndi HPMC kumatha kufalitsanso kupsinjika, potero kuchepetsa kupezeka kwa ming'alu.
5. Kusintha Kulimbana Kwaku Freeze-Thaw
HPMC imathandiziranso kukana mafayilo ndi mafayilo. Kuphatikiza kwamadzi kwa HPMC kumathandizira kufalitsa chinyezi mkati mwa mabongo ndi ma plaksters, kuchepetsa kuwonongeka kwaulere-thaw mkati mwa kuwonongeka kwaulere koyambitsidwa ndi chinyezi chifukwa cha chinyezi. Kuphatikiza apo, kafukufuku woteteza ku HPMC angalepheretse kulowerera chinyezi chakunja, potero kuchepetsa kuwonongeka kwa zinthu zomwe zimayambitsidwa ndi zibowo zakumadzi ndikuwonjezera moyo wa matope ndi ziphuphu.
6. Kuchulukitsa kuvala kukana
HPMC imasinthanso kuvala kukana kwa maboti ndi ma punya. Mwa kulimbikitsa kulimbikira ndi kachulukidwe ka matope, hpmc imapanga pamwambakati pazinthu zolimba, kuchepetsa zomwe zingatheke kuvala. Izi ndizofunikira makamaka kuti maphero pansi ndi khoma la makhoma, popeza maderawa nthawi zambiri amakhala amavutika kwambiri.
7. Sinthani ungwiro
HPMC imakhudzanso kufooka kwa mankhusu ndi ziphuphu. Kapangidwe ka kama filimuyo ya HPMC imapanga chotchinga chogwira cha matope ndi matope, kuchepetsa chimbudzi. Nthawi yomweyo, hpmc imathandizira kuchuluka kwa nkhaniyo, kuchepetsa ma pores mkati, potengera kuwongolera ungwiro. Izi ndizofunikira kwambiri polimbitsa zofunikira zakuthambo komanso zoziziritsa.
8. Kuchulukitsa maola otseguka
Nthawi yotseguka imanenanso za nthawi yomwe matope kapena a Stucco amakhalabe. HPMC imatha kukulitsa nthawi yotseguka kudzera mu madzi osasunga madzi, omwe ndi ofunikira kwambiri pomanga madera akulu kapena kugwira ntchito kutentha kwambiri komanso malo owuma. Nthawi yotseguka sikuti zimangowonjezera kusinthasintha komanso kuchepetsa zofooka zoyambitsidwa chifukwa cha matope kapena pulasitala kapena pulasitala kubuka mwachangu kwambiri.
Kugwiritsa ntchito HPMC kumati maboti ndi ma plakster kumapereka chitukuko chofunikira mu mitundu yambiri ya zinthuzi. Mwa kusungidwa kwamadzi, kulimbikitsa ntchito yopanga, kukulitsa kusokonezeka ndi kuphwanya, ndikusinthanso kuzunza kwakukulu, hpmc. Kusintha komweku kumangopanga kupanga kovuta kwambiri komanso kovuta, komanso kutsimikizika kwa nthawi yayitali ndi nyumbayo yomwe ili pansi pa chilengedwe. Chifukwa chake, HPMC yakhala yofunikira komanso yofunika pakupanga matope ndi a Stucco.
