Hydroxypropyl methylcellulose (HPMC) yolumikizidwa ndi gypsum

dziwitsani:

Hydroxypropyl methylcellulose (HPMC) yomangidwa ndi gypsum ndi chinthu chomangira chomwe chimaphatikiza zinthu za hydroxypropyl methylcellulose ndi gypsum.Kuphatikizika kwatsopano kumeneku kumapangitsa kuti pakhale zinthu zogwira ntchito kwambiri zokhala ndi ntchito zambiri pantchito yomanga.

Hydroxypropyl methylcellulose (HPMC):

1.1.Tanthauzo ndi katundu:

Hydroxypropyl methylcellulose, yemwe amadziwika kuti HPMC, ndi ether ya cellulose yochokera ku cellulose ya polima yachilengedwe.Kusungirako bwino kwa madzi, kukhuthala ndi kupanga mafilimu kumapangitsa kukhala chowonjezera chodziwika bwino m'mafakitale osiyanasiyana, kuphatikizapo zomangamanga.HPMC imadziwika ndi kusungunuka m'madzi otentha ndi ozizira, kupereka kusinthasintha mu ntchito zosiyanasiyana.

1.2.Ntchito muzomangamanga:

M'makampani omanga, HPMC imagwiritsidwa ntchito kwambiri ngati chowonjezera pazinthu zopangira simenti, matope ndi gypsum plasters.Kusunga kwawo madzi kumawonjezera kugwira ntchito ndikuwonjezera nthawi yoyika zinthuzi.HPMC imathandizanso kuwongolera kumamatira komanso kulimba, ndikupangitsa kuti ikhale gawo lofunikira la zomangamanga zamakono.

Gypsum plaster:

2.1.Zosakaniza ndi mawonekedwe:

Wopangidwa makamaka ndi calcium sulfate dihydrate, gypsum ndi nyumba yomangira yomwe imagwiritsidwa ntchito kwambiri yomwe imadziwika ndi kukana moto, kutsekereza mawu komanso kusalala pamwamba.Nthawi zambiri amagwiritsidwa ntchito ngati zokongoletsera za makoma ndi denga, zomwe zimapereka malo okongola komanso okhazikika.

2.2.Ntchito yomanga:

Gypsum pulasitala ali ndi ntchito zosiyanasiyana m'makampani omangamanga, kuphatikizapo makoma amkati, zinthu zokongoletsera ndi zoumba.Kusinthasintha kwake, kugwiritsa ntchito mosavuta komanso kukana moto kwabwino kumapangitsa kukhala chisankho choyamba pantchito zomanga nyumba ndi zamalonda.

HPMC yomangika gypsum pulasitala:

3.1.Njira yopanga:

Kupanga kwa gypsum yolumikizidwa ndi HPMC kumaphatikizapo kuphatikizidwa kwa hydroxypropyl methylcellulose mu matrix a gypsum.Izi zimatheka kudzera mu njira yosakanikirana yosakanikirana, kuonetsetsa kuti tinthu tating'onoting'ono ta HPMC timagawidwa mofanana mkati mwa matrix a gypsum.Zotsatira zake ndi zinthu zophatikizika zomwe zimatengera zabwino za HPMC ndi gypsum.

3.2.Makhalidwe a HPMC omangidwa gypsum:

Kuphatikiza kwa HPMC ndi gypsum kumapereka mawonekedwe apadera.Izi zikuphatikizapo kupititsa patsogolo ntchito, kumamatira bwino, nthawi yowonjezera yokhazikika komanso kukhazikika.Zosakaniza za HPMC zimathandizira kusunga chinyezi, kupewa kuyanika msanga ndikuwonetsetsa kuti kutha kofanana komanso kosalala.

Kugwiritsa ntchito gypsum yolumikizidwa ndi HPMC:

4.1.Wall amamaliza:

HPMC womangidwa gypsum pulasitala amagwiritsidwa ntchito ngati khoma zotchinga zakuthupi.Kuwongolera kwake kumapangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikumaliza, zomwe zimapangitsa kuti pakhale malo osalala komanso owoneka bwino.Nthawi yowonjezera yoperekedwa ndi HPMC imawonetsetsa kuti pulasitalayo ali ndi nthawi yokwanira kuti akwaniritse zomwe akufuna.

4.2.Makongoletsedwe okongoletsa:

Chophatikizikacho chimagwiritsidwanso ntchito popanga zokongoletsera zokongoletsera ndi zinthu zomanga.Kusinthasintha kwake kumapangitsa kuti pakhale zojambulajambula ndi tsatanetsatane, kupatsa omanga ndi okonza mapulani osiyanasiyana.

4.3.Kukonza ndi kuchira:

pulasitala yomangika ya HPMC ndi yoyenera kukonzanso ndi kukonzanso mapulojekiti pomwe kugwirizana kwake ndi pulasitala yomwe ilipo komanso kulimba kwake kumagwira ntchito yofunika kwambiri.Zimalola kukonzanso kosasunthika ndikutsimikizira moyo wautali wa malo okonzedwa.

Ubwino wa HPMC womangidwa gypsum:

5.1.Konzani kachitidwe:

Kuwonjezera HPMC kumawonjezera workability gypsum pulasitala, kupanga ntchito ndi kumaliza mosavuta.Izi ndizopindulitsa makamaka kwa opaka pulasitala chifukwa zimalola kuwongolera komanso kulondola kwambiri panthawi yopaka pulasitala.

5.2.Wonjezerani nthawi ya solidification:

Nthawi yowonjezera yoperekedwa ndi HPMC imawonetsetsa kuti pulasitalayo ali ndi nthawi yokwanira kuti amalize kugwiritsa ntchito ndikukwaniritsa zomwe akufuna.Izi ndizopindulitsa pama projekiti akuluakulu kapena komwe kuchedwa kuyika nthawi kumafunika.

5.3.Wonjezerani adhesion:

HPMC imathandizira kumamatira, zomwe zimapangitsa kuti pakhale mgwirizano wamphamvu pakati pa pulasitala ndi gawo lapansi.Katunduyu ndi wofunikira kwambiri pakukhalitsa komanso moyo wautali wa malo omalizidwa.

5.4.Kusunga madzi:

Kutha kwa madzi kwa HPMC kumalepheretsa kuyanika kwa pulasitala msanga, zomwe zimapangitsa kuti pakhale kutha komanso kosalala.Izi ndizofunikira makamaka kumadera ouma kapena pogwira ntchito pamalo akulu, pomwe kusakhazikika kwa chinyezi kumakhala kovuta.

5.5.Kusiyanasiyana kwa Design:

Kuphatikizika kwa pulasitala yomangika kwa HPMC iyi kumapangitsa kuti ikhale yosinthasintha pamapangidwe ndi kagwiritsidwe ntchito.Ikhoza kupangidwa m'mawonekedwe ndi maonekedwe osiyanasiyana, ndikupangitsa kuti ikhale yoyenera kwa miyambo yachikhalidwe komanso yamakono.

Pomaliza:

Pulasitala womangidwa ndi Hydroxypropylmethylcellulose (HPMC) akuyimira kupita patsogolo kwakukulu kwa zida zomangira.Mwa kuphatikiza zopindulitsa za HPMC ndi gypsum, gululi limapereka magwiridwe antchito bwino, nthawi yokhazikika yotalikirapo, kumamatira kumawonjezera komanso kusunga madzi.Izi zimapangitsa kukhala chisankho chosunthika komanso chofunikira pamitundu yosiyanasiyana yomanga, kuphatikiza zotchingira makoma, zomangira ndi kukonza mapulani.Pamene ntchito yomanga ikupitabe patsogolo, HPMC yomangidwa ndi pulasitala ya gypsum ikuwoneka ngati njira yokhazikika komanso yogwira ntchito kwambiri pamamangidwe amakono.
