Hydroxypylmmyl (HPMC) ndi yowonjezera kwambiri yogwiritsidwa ntchito kwambiri m'makampani omanga, makamaka mu mapulani a pulater. Gypsum Pulaster, omwe amadziwikanso kuti pulasitala wa Paris, ndi malo opangira nyumba yokongola omwe amagwiritsidwa ntchito kuvala makhoma ndi kudekha. HPMC imachita mbali yofunika kwambiri pokonza ndi magwiridwe antchito a gypsum.
HPMC ndi cellulose yopanda ionic ether ether eyd yochokera ku cellulose yachilengedwe kudzera pa cellulose ya polymer pogwiritsa ntchito njira zingapo za mankhwala. Imapangidwa ndi kuchiritsa cellulose ndi ma propylene oxide ndi methyl chloride. Zotsatira zake ndi ufa woyera womwe umasungunuka m'madzi ndikupanga yankho lowonekeratu.
Nazi zina mwazinthu zazikulu za HPMC ya Pulaster:
1. Kusunga kwamadzi:
Chimodzi mwazinthu zofunika kwambiri za HPMC ku gypsum ndi mphamvu yake. Zimathandiza kupewa chinyezi mwachangu panthawi yowuma, kulola kulamulidwanso komanso kuyika pulasitala. Izi ndizofunikira kuti mukwaniritse mphamvu zofunika kwambiri za pulasitiki.
2. Kupititsa patsogolo kuwongolera:
HPMC imathandizira kugwira ntchito kwa gypsum pulasitala ya gypsum popereka nthawi yotseguka ndikuwonjezera kukana. Izi zimapangitsa kuti ikhale yosavuta kuigwiritsa ntchito ndikufalitsa a Stucco pamtunda, zomwe zimapangitsa kuti maliza.
3. Zomvera ndi Coute:
Zithandizo za HPMC muzotsatira za gypsum piya kupita ku magawo osiyanasiyana. Zimakhala bwino pakati pa zitsamba zapakati pa Stucco ndi zokhazikika pamwamba, ndikuonetsetsa kuti kuli nthawi yayitali komanso yolimba. Kuphatikiza apo, HPMC imathandizira kuti chifunde cha pulasitiki, potero ndikuwonjezera mphamvu.
4. Zotsatira za kukula:
Mapangidwe a gypsum, hpmc amachita ngati thiccener, akukhudza mafayilo a gypsum osakaniza. Zotsatira zakumwambazi ndizofunikira kuti zithe kukwaniritsa zomwe mukufuna. Zimathandizanso kupewa stucco kuchokera kukwapula kapena kugwa pamalo owongoka.
5.
Kuwongolera nthawi yokhazikitsa pulasitala ya gypsum ndikofunikira mu zomangamanga. HPMC imatha kusintha nthawi yokhazikitsa kuti mupereke kusinthaku kuti mukwaniritse zofunika polojekiti. Izi ndizofunikira kwambiri pantchito zazikulu zomwe zingafunike nthawi zosiyanasiyana.
6. Zotsatira zojambula:
Kukhalapo kwa HPMC kumakhudzanso chidwi cha gypsum. GPMC yopangidwa bwino ndi HPMC imatha kuonjezera kukana madzi ndikuletsa kukhulupirika komanso kukana zinthu zachilengedwe.
7. Kugwirizana ndi zina zowonjezera:
HPMC imagwirizana ndi zowonjezera zina zowonjezera zomwe zimagwiritsidwa ntchito mu gypsum. Kusintha kumeneku kumapangitsa kuti pulasitala asamachitidwe kuti akwaniritse mfundo zachikhalidwe ndi zofunika pa ntchito.
8. Maganizo a Zachilengedwe:
HPMC nthawi zambiri imawoneka wotetezeka komanso wochezeka. Sikuti ndi poizoni ndipo sikumatulutsa zinthu zovulaza nthawi kapena mutatha kupaka. Izi ndizogwirizana ndi kutsindika komwe kumayambitsa kulimbitsa thupi kokhazikika komanso kwa Eco.
Hydroxypypyl methylcellulose (hpmc) yofunika kwambiri kukonza magwiridwe antchito a gypsum. Kusungidwa kwake kwamadzi, kusintha kwa kugwiritsidwa ntchito, kutsatira, kukulitsa mphamvu, kumapangitsa kuti kuwongolera nthawi, kuphatikizika ndi zowonjezera zomwe zimapangitsa kuti zikhale zosangalatsa kwambiri. Monga machitidwe omanga akupitiliza kusinthika, HPMC imakhala yofunika kwambiri pokonzanso ntchito ndi kulimba kwa pulasitala ya gypsum m'misika ndi ntchito zomanga.
