Hpmc mu pulasitala - zowonjezera bwino

Hydroxypypyl methylcellulose (hpmc) ndi polymer polymer omwe amagwiritsidwa ntchito kwambiri m'makampani osiyanasiyana kuphatikiza ntchito zomanga. M'mapulogalamu a gypslum, hpmc amakhala ngati chowonjezera chabwino chokhala ndi phindu lililonse lomwe limathandizira kukonza magwiridwe antchito komanso mtundu wa gypsum.

Kuyamba kwa hydroxypropyl methylcellulose:

Hydroxypropyl methylcelulose ndi polymer polymer yopangidwa ndi cellulose, chilengedwe chopezeka mu mbewu. HPMC imapangidwa ndi kuchiritsa cellulose ndi ma prolouse oxide ndi methyl chloride, zomwe zimapangitsa kuti pakhale zowonjezera za makolo. Mlingo wa zolowa m'malo mwa hydroxypyl ndi methoxy magulu oyambira a cellulose amasankha zomwe zimapangitsa kuti pakhale HPMC.

Mawonekedwe a HPMC:

Kusunga kwamadzi:
HPMC ili ndi madzi abwino osasunga madzi ndipo amatha kupanga filimu yopyapyala pamwamba pa gypsum kuti muchepetse madzi. Izi ndizofunikira kuti mukwaniritse bwino zochirikiza komanso kupewa kuyanika kwa stucco.

Makina otukuka:

Kuphatikiza kwa HPMC kumathandizira kugwiritsidwa ntchito kwa pulasitala, kumapangitsa kuti zisakanikize, kutsatira ndi kufalikira. Kusinthasintha kusasinthasintha kumathandizira kupatsa chotsatsa bwino ndikuphimba pamitundu yosiyanasiyana.

Olamulidwa nthawi:

HPMC imalola kuwongolera kwambiri pa nthawi ya pulasitala. Posintha zomwe zili mu HPMC, opanga amatha kusintha nthawi zina kuti akwaniritse zofunika kwambiri polojekiti, onetsetsani kuti agwiritse ntchito.

Onjezerani maola otsegulira:

Nthawi yotseguka ndi nthawi yomwe pulasitala imakhala yovuta isanakhazikitse. HPMC yakweza maola ake otsegulira kuti apatse amisiri ndi antchito omwe ali ndi nthawi yopumira kwambiri kuti agwiritse ntchito komanso kumaliza ntchito.

Kupititsa patsogolo:

Katundu wa filimuyo ya HPMC imathandizira kuwongolera mgwirizano pakati pa pulasitala ndi gawo lapansi. Izi ndizofunikira kwambiri kuonetsetsa kuti nditakhala ndi moyo wabwino kwambiri.

Kukana kukana:

HPMC imathandizira kuchepetsa kuchepa kwa ming'alu mu pulasitala pochulukitsa kusinthasintha ndi mphamvu zake. Izi ndizofunikira kuti mukhalebe ndi mtima wosagawanika kwa otsogola pamtunda.

Zabwino:

Rheogy amatanthauza njira yoyendera ndi kusokonekera kwa zida. HPMC imatha kusintha zinthu zaubweya wa gypsum, ndikupereka kusinthika komwe kukufunidwa kosavuta kugwiritsa ntchito mosavuta.

Kugwiritsa ntchito HPMC ku gypsum:

Gypsum Pulaster:

Mapangidwe a gypsum, hpmc nthawi zambiri amagwiritsidwa ntchito kukonza madzi osungidwa, ogwirira ntchito komanso kutsatira. Zimathandizanso kukhazikika nthawi ndikuwongolera momwe zimakhalira ndi glusco.

Kutulutsa kwa simenti:

HPMC imagwiritsidwa ntchito kwambiri m'makalasi a simenti omwe ali owonjezera kuti akwaniritse chiwerewere chofunikira, nthawi yolumikizana. Kulamulidwa nthawi ndi nthawi kumakhala kopindulitsa makamaka ntchito zomanga zazikulu.

Laimu phazi:

Mafuta a ma laimu amapindula ndi kuwonjezera kwa hpmc kuti apititse patsogolo madzi komanso kugwirira ntchito. Kugwirizana kwa polima ndi zinthu za Lime kumapangitsa kuti zikhale chisankho choyenera pa ntchito za cholowa ndi kubwezeretsanso.

Kutayika Kwanja ndi Kumaliza Mapulogalamu (Mauthenga):

HPMC ndi gawo limodzi lofunika kwambiri la magwiritsidwe, kuthandiza kukonza zotsatsa, kusinthasintha komanso kukana kukana. Malo ake osunga madzi ndiofunika kwambiri mu zinthu zakunja.

Pomaliza:

Hydroxypropyll methylcellulose ndi zowonjezera zabwino mu gypsum mawonekedwe chifukwa cha ntchito yake yosungirako madzi, kugwiritsidwa ntchito, kuwongolera nthawi, kutsatira nthawi. Kaya kagwiritsidwe ntchito pulasitala, simenti, laimu kapena khoma lakunja limagwira ntchito yofunika kwambiri pokonzanso magwiridwe antchito ndi pulasitala. Monga machitidwe omanga akupitiliza kusinthika, kusinthasintha kwa HPMC ndi kudalirika kwapanga kukhala gawo limodzi la ma puster amapangira ma pulasitiki amakono, ndikuwonetsetsa kukhala ndi moyo wabwino komanso kuchita bwino.
