Hydroxypropylmethylcellulose (HPMC) ndi polima wosunthika wogwiritsidwa ntchito m'mafakitale osiyanasiyana. Makhalidwe ake amapanga zinthu zamtengo wapatali, makamaka pomanga. HPMC imapereka maubwino angapo kuphatikiza kusunga bwino madzi, kuchepa kwa mayamwidwe amadzi komanso kupititsa patsogolo kachulukidwe. Nkhaniyi ikuwonetsa zaubwino wogwiritsa ntchito kamangidwe ka HPMC kuti muwonjezere kusunga madzi m'makoma ndikuchepetsa kuyamwa kwamadzi.
kuonjezera kusunga madzi
Ubwino wina waukulu wogwiritsa ntchito HPMC pomanga ndi kuthekera kwake kowonjezera kusunga madzi. Mukawonjezeredwa ku simenti kapena gypsum, HPMC imapanga maukonde omwe amatsekera madzi mkati. Izi zimathandiza kuti stucco zisaume ndi kuuma, ndikutalikitsa njira yochiritsa. Komanso, HPMC amapereka workability bwino kwa matope, amene n'kofunika ntchito yomanga kapena kukonza latsopano.
M'matope wamba, madzi amasanduka nthunzi mofulumira, zomwe zimapangitsa kuti zikhale zovuta kusakaniza mofanana. Izi zingayambitse malo ofooka pakumanga komaliza komanso ngakhale kusweka msanga. Pamene HPMC ikuwonjezeredwa kusakaniza, kusungirako madzi kumakhala bwino, kuonetsetsa kufanana ndi kusasinthasintha kwa kusakaniza. Izi zimathandizira kuti ntchitoyo ikhale yabwino, imathandizira kumamatira ku gawo lapansi, ndikuwongolera nthawi yochiritsa.
kuchepetsa kuyamwa kwa madzi
Ubwino wina wogwiritsa ntchito HPMC ndikuti ukhoza kuchepetsa kwambiri kuyamwa kwamadzi khoma. Sikoko wakunja ndi stucco ndi zida za porous zomwe ndi zabwino kuwongolera mpweya wamkati, komanso amakonda kuyamwa chinyezi. Makoma akamayamwa madzi, amawonongeka mosavuta chifukwa chinyonthocho chimafooketsa chipikocho, kuchititsa kuti ching’ambe ndi kusweka.
Mwamwayi, HPMC imatha kuchepetsa mayamwidwe amadzi pakhoma. Pophimba kunja kwa khoma ndi HPMC yopyapyala, imapanga chotchinga choteteza ku kulowa kwa chinyezi. Izi zimathandiza kuti madzi asalowe m'makoma, kuchepetsa kuwonongeka kwa nthawi.
kusunga bwino madzi
HPMC ili ndi zinthu zabwino kwambiri zosungira madzi, zomwe zimapindulitsanso ntchito yomanga ndi zomaliza. Ndikofunikira kuti akatswiri ogwira ntchito yomanga aziwongolera bwino zida ndi zida zawo. HPMC imaonetsetsa kuti chinyezi chambiri komanso choyendetsedwa bwino mu stucco, pulasitala kapena matope, zomwe zimapangitsa kuchiritsa kofanana.
Kusungidwa bwino kwa madzi kumatanthauzanso kuti pulasitala kapena pulasitala idzalumikizana bwino ndi gawo lapansi. Kusakaniza kumakhala konyowa kwa nthawi yayitali, kulola kuti zosakanizazo zigwirizane bwino ndikupanga mgwirizano wamphamvu. Kulumikizana bwino kumapangitsa kuti khoma likhale lolimba, ngakhale m'malo ovuta.
Pomaliza
HPMC ndichinthu chofunikira kwambiri pantchito yomanga. Ubwino wake pakuwonjezera kusungidwa kwamadzi, kuchepetsa kuyamwa kwamadzi, komanso kukulitsa magwiridwe antchito kumapangitsa kuti pakhale ntchito yomanga kapena kukonza. Kugwiritsa ntchito kalasi yomanga HPMC kumatha kuchepetsa kwambiri kuyamwa kwamadzi khoma ndikukhala ndi zinthu zabwino zosungira madzi. HPMC ndi chinthu chamtengo wapatali chomwe chili chothandiza kwa akatswiri omanga, kuwathandiza kupanga makoma olimba, apamwamba kwambiri ndi zomangamanga.
