Kodi dry mortar mu chemistry ndi chiyani?

Dry mortar ndi mtundu wa zida zomangira zomwe zimagwiritsidwa ntchito pomanga ndi kusindikiza zida zomangira monga njerwa, midadada, ndi miyala.Ndi chisakanizo cha simenti, mchenga, ndi zowonjezera zina, ndipo amagwiritsidwa ntchito ngati chomangira kuti agwirizanitse zigawozo pamodzi.Tondo wowuma amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo kumanga, kupaka pulasitala, ndi matayala.

Dothi louma ndi losakaniza la simenti, mchenga, ndi zinthu zina, monga laimu, gypsum, ndi madzi.Simenti imagwira ntchito ngati chomangira, pomwe mchenga umapereka zochuluka zazinthuzo.Zowonjezera zina zimagwiritsidwa ntchito kusintha zinthu za matope, monga mphamvu yake, kugwira ntchito, ndi kukana madzi.Kuchuluka kwa chigawo chilichonse chomwe chimagwiritsidwa ntchito mu kusakaniza kumadalira kugwiritsa ntchito komanso zofunikira za matope.

Mtundu wofala kwambiri wa matope owuma ndi matope a simenti a Portland, omwe amapangidwa ndi simenti ya Portland, mchenga, ndi madzi.Tondo wamtunduwu umagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza zomanga, zopaka pulasitala, ndi matayala.Amagwiritsidwanso ntchito popanga ndi kudzaza zolumikizira pakati pa njerwa ndi miyala.

Mitundu ina ya matope owuma ndi monga laimu mortar, gypsum mortar, ndi masonry simenti.Mtondo wa laimu umagwiritsidwa ntchito pomanga ndi kupaka pulasitala, ndipo amapangidwa ndi laimu, mchenga, ndi madzi.Dothi la gypsum limagwiritsidwa ntchito popangira matayala ndipo amapangidwa ndi gypsum, mchenga, ndi madzi.Masonry simenti amagwiritsidwa ntchito pomanga ndipo amapangidwa ndi simenti ya Portland, laimu, ndi mchenga.

Kusakaniza kwamatope owuma kumakonzedwa mwa kuphatikiza zosakaniza zouma mu chosakaniza.Zosakaniza zimasakanizidwa mpaka kugwirizana kwa yunifolomu kumapezeka.Kusakaniza ndikokonzeka kugwiritsidwa ntchito.

Mukamagwiritsa ntchito matope owuma, ndikofunikira kutsatira malangizo a wopanga kusakaniza ndi kugwiritsa ntchito.Mtondo uyenera kusakanikirana ndikugwiritsidwa ntchito motsatira malangizo a wopanga kuti atsimikizire zotsatira zabwino.

Dry mortar ndi zida zomangira zosunthika zomwe zimagwiritsidwa ntchito m'njira zosiyanasiyana.Ndi yosavuta kugwiritsa ntchito ndipo imapereka mgwirizano wamphamvu, wokhazikika pakati pa zipangizo zomangira.Ndikofunika kutsatira malangizo a wopanga mukamagwiritsa ntchito matope owuma kuti muwonetsetse zotsatira zabwino.
