Hpmc (hydroxypropyl methylcellulose) ndiowonjezera nthawi zambiri amagwiritsidwa ntchito pomanga pulasitala, makamaka pokonza madzi, miyambo ndi ntchito yomanga pulasitala.
1. Sinthani madzi osungira za pulasitala
HPMC ndi polymer polymer polymer yomwe imatha kupanga ma network mu simenti kapena gypsum-porse. Izi zimathandizanso kusunga madzi ndikulepheretsa simenti kapena gypsum kuti isataye madzi mwachangu kwambiri panthawi yolimba, popewa kusokoneza kapena kuchepetsa madzi. Powonjezera kuchuluka kwa HPMC ku pulasitala, njira zamagetsi za simenti zitha kuchedwa kuchedwa, kupanga pulasitala kukhala ndi kuthekera bwino kusunga madzi. Ma hydrate opangidwa ndi simenti nthawi ya hydratic njira amafunika madzi okwanira kupititsa patsogolo zomwe zikuchitikazo. Kuchedwetsa kuwonongeka kwa madzi kumatha kusintha kachulukidwe ka kachulukidwe kazinthu zomaliza.
2. Sinthani chotsatsa ndi kachulukidwe ka pulasitala
Monga owonjezera polymer, hpmc silingangowonjezera mphamvu za pulasitala, komanso kusintha komatira. HPMC ikawonjezeredwa, kulimba kwa pulasitala kumakulitsa, komwe kumathandizira kupanga chotsatsa champhamvu kwambiri (monga njerwa, Khomi kapena Graplum Khoma). Nthawi yomweyo, hpmc imapanga pulasitala kupanga kapangidwe kambiri nthawi yolimbana, kuchepetsa kukhalapo kwa ma capillary pores. Pores ochepa amatanthauza kuti ndizovuta kuti madzi kulowa, motero amalimbikitsa madzi kukana pulasitala.

Kupanga kwa nthawi ya HPMC kumatha kupanga chinthu chofanana ndi pulasitala, kulola pulasitala kuti apange microstrucructurer muyeso pakuchiritsa. Kapangidwe kameneka, pulasitala imasanduka yosalala komanso yotentha, ndipo kuvomerezedwa kwamadzi kumachepetsedwa. Chifukwa chake, kukana kwamadzi kwa pulasitalayo kwasintha, makamaka m'malo olemera kapena olemera m'madzi, kuwonjezera kwa hpmc moyenera kupewa chinyezi kulowa khoma kudutsa khoma.
4. Kukhazikika kwabwino komanso kusakhazikika
Kukaniza kwa madzi kumangotengera kuthekera kwamadzi kwa zinthuzo, komanso zogwirizana kwambiri ndi kapangidwe ka pulasitala. Powonjezera hpmc, kukhazikika kwa thupi ndi kwamankhwala kwa pulasitala kumatha kusintha. HPMC imasintha mankhwala opondera ma pulasitala ndipo amapewa ma simenti oyambitsidwa ndi simenti. Makamaka pakumizidwa kwa nthawi yayitali kapena malo achinyontho, hpmc amathandizira kukulitsa moyo wa pulasitala ndikuwonjezera katundu wake wotsutsa.
5. Sinthani ma viccle ndi kugwirira ntchito
Hpmc Alinso ndi ntchito yosintha mafayilo ndi miyambo yachinyengo. Makamaka, mafayilo oyenera amatha kupangitsa kuti donsayo ikhale yosavuta kutuluka, ndipo imatha kuphimbidwa khomalo popanda kuyambitsa pulasitala kuti igwere pakupanga chinyezi chifukwa cha chinyezi chochuluka. Mwa kuwongolera kugwiritsidwa ntchito kwa pulasitala, ogwira ntchito zomanga akhoza kukonzanso kufanana kwa pulasitala, potero mosakhalitsa anasintha magwiridwe antchito a pulasitala.
6. Exever kukana
Pulogalamu yomanga, pulasitala imakonda kuchepera kwa zinthu zakunja monga kutentha kwa kutentha ndi chinyezi, zomwe zimayambitsa ming'alu. Kukhalapo kwa ming'alu sikumakukhudzani ma pulasitala, komanso kumapereka njira yolowera yamadzi. Kuphatikiza kwa HPMC kumatha kuwonjezera kulimba kwa pulasitala, ndikupangitsa kuti pakhale kukana kwamphamvu panthawi yowuma, popewa chinyontho kuti musalowe mkati kudutsa ming'alu ndikuchepetsa chiopsezo chamadzi.
7. Sinthani kusinthasintha komanso zomangamanga
Kuphatikiza kwa HPMC kumatha kupanganso pulasitala mosalekeza mosiyanasiyana. Mu malo otentha kwambiri, chinyezi cha pulasitili chikutuluka mwachangu kwambiri ndipo chimakonda kuwonongeka. Kukhalapo kwa HPMC kumathandizira kuti pulasitala asungire madzi owuma, kotero kuti liwiro lake limayendetsedwa komanso kuwonongeka kwa osanjikiza ndi kuwonongeka kwa madzi oyambitsidwa ndi kuwuma msanga kwambiri kumapeweka. Kuphatikiza apo, HPMC imatha kukonzanso zomata za pulasitala, kuti ithe kukhalabe odetsa m'malo osiyanasiyana ndipo sikophweka kugwa.
HPMC imagwira ntchito yofunika kwambiri kukonza madzi kukana pulasitala, makamaka kudzera patsamba lotsatira:
Kusungidwa kwamadzi: Chementant CEAmetration, kusunga chinyontho, ndikupewa kuyanika kwambiri.
Kutsatira ndi Kuchulukitsa: Kuchulukitsa chotsatira cha pulasitala pansi mpaka pangani mawonekedwe.
Kutsutsa kopitilira: kuchepetsa ma pores ndipo pewani kulowetsedwa kwamadzi.
Kukhazikika ndi kusautsa kwa madzi: Sinthani kukhazikika kwa mankhwala ndi kukulitsa moyo wa ntchito.
Kutsutsa kosweka: Kuchulukitsa kulimba kwa pulasitala ndikuchepetsa mapangidwe a ming'alu.
Kumanga moyenera: Sinthani zopanga zanyengo ndikusintha kuchepa kwa ntchito pomanga. Chifukwa chake, hpmc sikuti ndizowonjezera kusintha magwiridwe antchito a pulasitala, komanso kumathandizanso kukana madzi pogwiritsa ntchito makina ambiri komanso kukhazikika kwanthawi yayitali m'malo osiyanasiyana.
