Kodi ndikofunikira kuchita chithandizo cha primer chotsutsana ndi alkali musanapopere utoto weniweni wa miyala?

1. Kodi utoto weniweni wa miyala ndi chiyani?

Utoto weniweni wa miyala ndi utoto wapadera womwe umapanga mawonekedwe ofanana ndi marble, granite, matabwa ndi zinthu zina zamwala pamwamba pa nyumba. Woyenera kujambula makoma amkati ndi akunja, denga, pansi ndi malo ena okongoletsera. Zigawo zazikulu za utoto weniweni wa miyala ndi utomoni, utoto ndi zodzaza. Nthawi yogwira ntchito yake komanso mphamvu zake zimadalira mtundu ndi kukhazikika kwa pamwamba pa utoto.

2. N’chifukwa chiyani kuli kofunikira kuchita chithandizo cha primer chosagonjetsedwa ndi alkali?

Kupanga utoto weniweni wa miyala kumafuna kugwiritsa ntchito primer yosagwira alkali pochizira zinthu zoyambira. Izi zili choncho chifukwa pamwamba pa nyumbayo pamakhala zinthu zolimba za alkali monga simenti ndi matope. Calcium hydroxide yomwe ili mu simenti ndi yokwera, ndipo pH yake ili pakati pa 10.5 ndi 13, zomwe zimakhudza kapangidwe ka mankhwala a utoto weniweni wa miyala. Kuwonongeka kungayambitse mavuto monga kusweka ndi kuchotsedwa kwa utoto.

Chomera cholimba chomwe sichimalimbana ndi alkali chili ndi zowonjezera monga polymer fatty amide, zomwe zimatha kugwirizana bwino ndi simenti ndi matope. Chimawonjezeranso kukana kwa utoto weniweni wa miyala ku zinthu za alkaline, ndikutsimikizira kuti pamwamba pa utoto pali mtundu komanso kukhazikika. Chifukwa chake, ndikofunikira kwambiri kuchita chithandizo cha chomera cholimba chomwe sichimalimbana ndi alkali musanapopere utoto weniweni wa miyala.

3. Kodi mungagwiritse ntchito bwanji primer yosagwira alkali?

Mukapaka primer yosagwira alkali, choyamba muyenera kupukuta pamwamba pa nyumbayo kuti muwonetsetse kuti pamwamba pake pali poyera, posalala, komanso popanda mafuta, fumbi ndi zinyalala zina. Kenako gwiritsani ntchito primer yapadera yosagwira alkali kuti muyike bwino kuti igwiritsidwe ntchito mofanana komanso makulidwe ake azikhala ofanana. Pambuyo poti primer yatha, iyenera kuuma bwino ndikulimba musanapopere utoto weniweni wa miyala.

4. Chidule

Chifukwa chake, ndikofunikira kwambiri kuchita chithandizo cha primer chosagwira alkali musanapopere utoto weniweni wa miyala, zomwe zingatsimikizire kuti pamwamba pa utoto pali bwino komanso pali kukhazikika, kupewa ming'alu, kusweka ndi mavuto ena, ndikuwonjezera nthawi yogwira ntchito komanso kukongola kwa utoto weniweni wa miyala.
