HPMC mu Plastering Plaster

Hydroxypropyl Methylcellulose (HPMC) amagwiritsidwa ntchito popaka pulasitala kuti azitha kugwira bwino ntchito, kumamatira, komanso kugwira ntchito kwa zosakaniza za pulasitala. Umu ndi momwe HPMC imagwiritsidwira ntchito popaka pulasitala:

  1. Kusunga Madzi: HPMC ili ndi malo abwino kwambiri osungira madzi, kuwalola kuti asunge madzi mkati mwa pulasitala. Izi zimathandiza kupewa kutayika kwamadzi mwachangu panthawi yopaka ndi kuchiritsa, kuonetsetsa kuti zinthu za simenti zikulowa madzi okwanira komanso kulimbikitsa kuyika bwino ndi kuchiritsa pulasitala.
  2. Kupititsa patsogolo Ntchito: HPMC imagwira ntchito ngati rheology modifier, kukonza magwiridwe antchito komanso kusasinthika kwa zosakaniza za pulasitala. Zimachepetsa kukhuthala kwa kusakaniza, kuti zikhale zosavuta kugwiritsa ntchito, kufalikira, ndi kugwira ntchito. Izi ndizofunikira kwambiri kuti pakhale malo osalala komanso ofanana pakupaka pulasitala.
  3. Kumamatira Kwabwino: HPMC imakulitsa zomatira za pulasitala, kulimbikitsa kulumikizana bwino pakati pa pulasitala ndi gawo lapansi. Izi zimabweretsa kulimba kwamamatira, kung'amba pang'ono, komanso kulimba kwa dongosolo la pulasitala.
  4. Crack Resistance: Pokonza zomatira komanso kuchepetsa kuchepa, HPMC imathandizira kuchepetsa kuchitika kwa ming'alu pamiyala ya pulasitala. Izi ndizopindulitsa makamaka popaka pulasitala kunja, komwe kukhudzana ndi zinthu zachilengedwe monga kusintha kwa kutentha ndi chinyezi kungayambitse kusweka.
  5. Sag Resistance: HPMC imathandizira kuchepetsa kugwa ndi kugwa kwa pulasitala panthawi yopaka, makamaka pamalo oyimirira. Izi zimatsimikizira kuti pulasitalayo imasunga makulidwe ake omwe amafunidwa komanso ofanana, kuteteza kusagwirizana ndikuonetsetsa kuti kutha kwapamwamba.
  6. Nthawi Yokhazikitsira Nthawi: HPMC itha kugwiritsidwa ntchito kuwongolera nthawi yosakanikirana ya pulasitala, kulola kuti nthawi yogwira ntchito ikhale yotalikirapo kapena kufulumizitsa ngati pakufunika. Izi zimapereka kusinthasintha pakugwiritsa ntchito ndikulola kuwongolera bwino pakuchiritsa ndi kuyanika kwa pulasitala.
  7. Mlingo ndi Kagwiritsidwe: Mlingo wa HPMC popaka pulasitala nthawi zambiri umachokera pa 0.1% mpaka 0.5% pa kulemera kwa kusakaniza kowuma, kutengera zofunikira za pulogalamuyo komanso mawonekedwe omwe pulasitala amafunikira. HPMC nthawi zambiri imawonjezedwa kusakaniza kowuma musanasakanize ndi madzi, kuwonetsetsa kubalalitsidwa kwa yunifolomu posakaniza pulasitala.

HPMC imagwira ntchito yofunika kwambiri pakuwongolera magwiridwe antchito, kugwira ntchito, komanso kulimba kwa pulasitala, kupangitsa kuti ikhale chowonjezera chofunikira pakupaka pulasitala mkati ndi kunja.
