HPMC yogwiritsidwa ntchito mu Aerated Concrete Blocks Laying Mortars

HPMC, kapena hydroxypropyl methylcellulose, amagwiritsidwa ntchito ngati chowonjezera popanga midadada ya konkriti ya aerated kuyala matope. Mitsuko ya konkriti yokhala ndi mpweya ndi yopepuka komanso ya porous, zomwe zimawapanga kukhala zida zabwino zomangira zomwe zimafunikira kutchinjiriza komanso kugwiritsa ntchito mphamvu.

Imodzi mwa ntchito zazikulu za HPMC mu aerated konkire midadada atagona matope ndi kuchita monga thickener ndi rheology kusintha. Kuphatikizika kwa HPMC mumatope kumawongolera magwiridwe antchito ake komanso kufalikira, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikugwira nayo ntchito. HPMC imapangitsanso kusasinthika ndi kukhazikika kwa matope, kuchepetsa chiopsezo cha kugwa kapena kugwa panthawi yogwiritsira ntchito.

Kuphatikiza pa kukhuthala kwake, HPMC imagwiranso ntchito ngati chomangira komanso chopangira mafilimu muzitsulo za konkriti zokhala ndi mpweya woyika matope. Kuphatikizika kwa HPMC mumatope kumawonjezera kumamatira kwake ku gawo lapansi, ndikupanga mgwirizano wamphamvu komanso wokhazikika. HPMC imapanganso filimu yoteteza pamwamba pa matope, yomwe imathandiza kuteteza ku mphepo ndi kukokoloka.

Phindu lina logwiritsa ntchito HPMC muzitsulo za konkriti zokhala ndi mpweya ndikuyika matope ndikuti zitha kuthandiza kukulitsa kukana kwa matope kuti kung'ambike ndi kuchepa. HPMC imatha kusunga madzi mumtondo, womwe umathandizira kuti ukhale wonyowa komanso kuti usawume mwachangu. Izi zingathandize kupewa ming'alu ndi kung'ambika, zomwe zingakhale vuto lofala muzitsulo za konkriti zoyalidwa ndi mpweya.

HPMC imathanso kupititsa patsogolo kulimba ndi mphamvu ya midadada ya konkriti yokhala ndi mpweya pakapita nthawi. Ikhoza kupititsa patsogolo kukana kwamatope kumadzi, mankhwala, ndi abrasion, zomwe zingathandize kukulitsa moyo wake wautumiki ndi kuchepetsa kufunika kokonzanso mtsogolo.

Kuphatikiza apo, HPMC ndi polima zachilengedwe, zongowonjezwdwa, komanso zowola zomwe zimachokera ku cellulose, zomwe zimakhala zambiri muzomera. Sichiwopsezo ndipo sichitulutsa zinthu zovulaza m'chilengedwe, zomwe zimapangitsa kuti zikhale zowonjezera zachilengedwe.

Ponseponse, kuwonjezera kwa HPMC ku midadada yoyika konkriti yokhala ndi mpweya kumapereka maubwino angapo, kuphatikiza kugwirira ntchito bwino, kumamatira, komanso kulimba. HPMC imathandizanso kuteteza matope kuti asagwere ndi kukokoloka, ndipo amatha kuteteza kusweka ndi kuchepa. Ndizowonjezeranso zachilengedwe, zomwe zimapindulitsa kwa ogwiritsa ntchito komanso chilengedwe.
