Kodi ndikofunikira kuchita chithandizo cha anti-alkali primer musanayambe kupopera utoto weniweni wamwala?

1. Kodi utoto weniweni wamwala ndi chiyani?

Utoto weniweni wamwala ndi utoto wapadera womwe umapanga mapangidwe ofanana ndi miyala ya marble, granite, matabwa ndi zipangizo zina zamwala pamwamba pa nyumba. Oyenera kujambula makoma amkati ndi akunja, denga, pansi ndi malo ena okongoletsera. Zigawo zazikulu za utoto weniweni wa miyala ndi resin, pigment ndi fillers. Moyo wake wautumiki ndi mphamvu zimadalira khalidwe ndi kukhazikika kwa utoto pamwamba.

2. N'chifukwa chiyani kuli koyenera kuchita chithandizo chamankhwala cholimbana ndi alkali?

Kupanga utoto weniweni wamwala kumafuna kugwiritsa ntchito zoyambira zolimbana ndi alkali pamankhwala oyambira. Izi zili choncho chifukwa nyumba yomangirayo imakhala ndi zinthu zolimba zamchere monga simenti ndi matope. Ma calcium hydroxide mu simenti ndi okwera, ndipo pH yake ili pakati pa 10.5 ndi 13, zomwe zidzakhudza kapangidwe kake ka utoto weniweni wamwala. Kukhudzidwa kungayambitse mavuto monga kung'amba ndi kupukuta utoto.

Zoyamba zosagwira alkali zimakhala ndi zowonjezera monga polima mafuta amide, omwe amatha kugwirizana bwino ndi simenti ndi matope. Zimawonjezeranso kukana kwa utoto weniweni wa miyala ku zinthu za alkaline, kuonetsetsa ubwino ndi kukhazikika kwa penti pamwamba. Chifukwa chake, ndikofunikira kuchita chithandizo cha alkali-resistant primer musanayambe kupopera utoto weniweni wamwala.

3. Momwe mungayikitsire choyambira chosamva alkali?

Mukamagwiritsa ntchito mankhwala olimbana ndi alkali, choyamba muyenera kupukuta pamwamba pa nyumbayo kuti muwonetsetse kuti pamwamba pa nyumbayo ndi yoyera, yosalala, yopanda mafuta, fumbi ndi zonyansa zina. Kenako gwiritsani ntchito choyambira chapadera chosamva alkali poyambira kuti mutsimikizire ngakhale kugwiritsa ntchito komanso makulidwe ake. Mankhwala oyambira akamaliza, ayenera kuumitsidwa ndikuwumitsidwa musanapope utoto weniweni wamwala.

4. Mwachidule

Choncho, m'pofunika kwambiri kuchita mankhwala oyambirira a alkali-resistant musanayambe kupopera utoto weniweni wamwala, womwe ungatsimikizire ubwino ndi kukhazikika kwa utoto, kuteteza kusweka, kupukuta ndi mavuto ena, ndikuwonjezera moyo wautumiki ndi kukongola kwa penti yeniyeni ya miyala.
