Ntchito Yomanga Hydroxypropyl Methylcellulose(HPMC)

Minda yofunsira

1.Kumanga:
Monga chosungira madzi komanso chochepetsera matope a simenti, zimapangitsa kuti matopewo azipopa.Amagwiritsidwa ntchito ngati chomangira mu pulasitala, putty ufa kapena zida zina zomangira kuti azitha kufalikira ndikutalikitsa nthawi yotseguka.Katundu wosungira madzi wa hydroxypropyl methylcellulose HPMC amalepheretsa slurry kusweka chifukwa cha kuyanika mwachangu mukatha kugwiritsa ntchito, komanso kumawonjezera mphamvu mukaumitsa.
1) Zomatira za matailosi
Zomatira za matailosi wamba zimakwaniritsa zofunikira zonse zamphamvu zomatira za C1 zomatira.Mwachidziwitso, amatha kukhala ndi mphamvu yopumira bwino kapena kukhala ndi nthawi yotseguka.Zomatira zamatayilo wamba zitha kukhala zokhazikika kapena zokhazikika mwachangu.
Zomata za matailosi a simenti ziyenera kukhala zosavuta kuzipumira.Ayenera kupereka nthawi yayitali yophatikizira, kukana kwambiri kutsetsereka komanso mphamvu yomatira yokwanira.Zinthu izi zitha kutengera HPMC.Zomatira zomangira midadada zimagwiritsidwa ntchito pomanga makoma a midadada ya konkriti, njerwa za mchenga kapena njerwa wamba.Zomata za matailosi zimatsimikizira mgwirizano wabwino pakati pa gawo lapansi ndi matabwa oteteza.HPMC bwino workability wa matailosi zomatira ndi kumawonjezera onse adhesion ndi sag kukana.
• Kuthekera kogwira ntchito bwino: kutsekemera ndi pulasitiki wa pulasitala kumatsimikizika, matope amatha kuikidwa mosavuta komanso mwachangu.
•Kusunga madzi bwino: Kutsegula kwa nthawi yayitali kumapangitsa kuti matayala azikhala bwino.
•Kumamatira bwino komanso kukana kutsetsereka: makamaka kwa matailosi olemera.

2) Chowumitsa matope osakaniza
Dothi lowuma losakanikirana ndi zosakaniza za mineral binders, aggregates ndi othandizira.Kutengera ndi ndondomekoyi, pali kusiyana pakati pa kugwiritsa ntchito dzanja ndi makina.Amagwiritsidwa ntchito popangira maziko, kusungunula, kukonzanso ndi kukongoletsa zolinga.Mtondo wosakaniza wowuma pogwiritsa ntchito simenti kapena simenti / hydrated laimu ungagwiritsidwe ntchito kunja ndi mkati.Makina opangidwa ndi makina amasakanikirana mosalekeza kapena mosalekeza pamakina opaka pulasitala.Izi zimathandiza kuphimba makoma akuluakulu ndi denga pogwiritsa ntchito njira yabwino kwambiri.
• Kusakaniza kosavuta kowuma chifukwa cha kusungunuka kwa madzi ozizira: mapangidwe a mtanda amatha kupewedwa mosavuta, abwino kwa matailosi olemera.
• Kusungirako bwino kwa madzi: kupewa kutaya madzi kumadzimadzi, madzi oyenerera amasungidwa mosakaniza zomwe zimatsimikizira nthawi yaitali ya concreting.

3) Kudziletsa
Zodzipangira zokha pansi zimagwiritsidwa ntchito kusalaza ndi kusanja mitundu yonse ya magawo ndipo atha kugwiritsidwa ntchito ngati chotchinga chamkati mwachitsanzo matailosi ndi makapeti.Kuti mupewe sedimentation ndikusunga kuyenda bwino, magiredi otsika a viscosity HPMC amagwiritsidwa ntchito.
• Kutetezedwa ku madzi otuluka ndi matope.
• Palibe zotsatira pa slurry fluidity ndi otsika mamasukidwe akayendedwe
HPMC, pomwe mawonekedwe ake osungira madzi amawongolera magwiridwe antchito pamtunda.

4) Crack Filler
·Kugwira ntchito bwino: makulidwe oyenera ndi pulasitiki.
· Kusunga madzi kumapangitsa kuti ntchito ikhale yayitali.
· Kukana kwa Sag: luso lolumikizana bwino ndi matope.

5) Gypsum based Plaster
Gypsum ndi chida chokhazikitsidwa bwino chomwe chimagwiritsidwa ntchito mkati.Imapereka magwiridwe antchito abwino ndipo nthawi yake yokhazikitsa imatha kusinthidwa pakugwiritsa ntchito kulikonse komwe kukufunika.Zipangizo zomangira za Gypsum zimapanga malo okhala bwino chifukwa cha chinyezi chabwino.Kuonjezera apo, gypsum imasonyeza bwino kukana moto.Komabe, simadzimadzi, choncho kugwiritsa ntchito mkati kokha n'kotheka.Kuphatikiza kwa gypsum ndi hydrated laimu ndizofala kwambiri pamapangidwe a pulasitala.
• Kuchuluka kwa madzi: nthawi yotseguka yowonjezereka, malo otambalala a spry ndi kupangika kwachuma.
• Kufalira kosavuta komanso kusinthika kwamphamvu kolimba chifukwa cha kusasinthika kwabwino.

6) Wall putty / Skimcoat
•Kusunga madzi: kuchulukitsa madzi mu slurry.
• Anti-sagging: Pofalitsa malaya okhuthala amatha kupewedwa.
•Kuchuluka kwa zokolola zamatope: kutengera kulemera kwa kusakaniza kowuma ndi kapangidwe koyenera, HPMC imatha kuwonjezera kuchuluka kwamatope.

7) Kutulutsa Kwakunja ndi Kumaliza System (EIFS)
Cementitious woonda bedi zomatira ntchito kumamatira matailosi ceramic, kumanga makoma aerated konkire kapena laimu njerwa miyala ndi kukhazikitsa kunja insulating kutsirizitsa machitidwe (EIFS) .Amapereka ntchito yosavuta ndi yopepuka, Mwachangu mkulu ndi kutsimikizira kulimba kwautali.
•Kumamatira bwino.
•Kunyowetsa bwino kwa bolodi la EPS ndi gawo lapansi.
•Kuchepa kwa mpweya komanso kutulutsa madzi.
1. Makampani omangamanga: Monga chosungira madzi komanso chochepetsera matope a simenti, zimapangitsa kuti matopewo azipopa.Amagwiritsidwa ntchito ngati chomangira mu pulasitala, pulasitala, putty ufa kapena zinthu zina zomangira kuti azitha kufalikira ndikutalikitsa nthawi yogwira ntchito.Itha kugwiritsidwa ntchito kuyika matailosi a ceramic, nsangalabwi, zokongoletsera za pulasitiki, zowonjezera zowonjezera, komanso zimatha kuchepetsa kuchuluka kwa simenti.Katundu wosungira madzi wa hydroxypropyl methylcellulose HPMC amalepheretsa slurry kusweka chifukwa cha kuyanika mwachangu mukatha kugwiritsa ntchito, komanso kumawonjezera mphamvu mukaumitsa.

2. Makampani opanga Ceramic:
amagwiritsidwa ntchito kwambiri ngati chomangira popanga zinthu za ceramic.

3. Makampani opaka:
Monga thickener, dispersant ndi stabilizer mu makampani ❖ kuyanika, izo zimagwirizana bwino m'madzi kapena organic solvents.Monga chochotsera utoto.

4.Kusindikiza kwa inki:
Monga thickener, dispersant ndi stabilizer mu makampani inki, izo zimagwirizana bwino m'madzi kapena zosungunulira organic.

5.Pulasitiki:
amagwiritsidwa ntchito ngati zosungunulira nkhungu, zofewa, zothira mafuta, etc.

6.Polyvinyl chloride:
Amagwiritsidwa ntchito ngati dispersant popanga polyvinyl kolorayidi ndipo ndiye wothandizira wamkulu pokonzekera PVC ndi kuyimitsidwa kwa polymerization.
