Kodi ndi ntchito ziti ndi zofunika za zida zosiyanasiyana mu matope odziyimira pawokha a gypsum?

Gypsum-based self-leveling mortar ndi mtundu wa zinthu zapansi zomwe zimagwiritsidwa ntchito kwambiri pomanga. Ndi kuphatikiza kwa zinthu zosiyanasiyana, kuphatikiza gypsum, aggregates, ndi zowonjezera, zomwe zidapangidwa kuti zipange malo osalala komanso osalala. M'nkhaniyi, tikambirana ntchito ndi zofunika za zipangizo zosiyanasiyana mu gypsum-based self-leveling matope.

1. Gypsum Gypsum ndiye chinthu chofunikira kwambiri pamatope odzipangira okha. Ndi mchere wachilengedwe womwe umakumbidwa kuchokera kudziko lapansi ndikuupanga kukhala ufa wabwino. Gypsum imapereka ntchito zingapo zofunika pamatope odzipangira okha, kuphatikiza:

• Kumanga: Gypsum imagwira ntchito ngati chomangira, kugwira zinthu zina zosakaniza pamodzi.
• Kukhazikitsa: Gypsum imakhazikika mwachangu ikasakanizidwa ndi madzi, zomwe zimapangitsa kuti matopewo akhale olimba ndikupanga malo olimba.
• Kusalala: Gypsum ndi yosalala mwachilengedwe ndipo imatha kuthandiza kuti pakhale kusalala pamwamba pamatope.

Ubwino wa gypsum womwe umagwiritsidwa ntchito posakaniza ndi wofunikira, chifukwa ungakhudze mphamvu ndi nthawi yoyika matope. Gypsum iyenera kukhala yopanda zodetsa ndi zonyansa, ndipo iyenera kukhala yofanana kukula kwa tinthu.

2. Aggregates Aggregates amagwiritsidwa ntchito mumatope odzipangira okha kuti apereke zambiri komanso mawonekedwe. Nthawi zambiri amapangidwa ndi mchenga kapena zinthu zina zokongoletsedwa bwino. Zosakaniza zomwe zimagwiritsidwa ntchito posakaniza ziyenera kukhala zoyera, zopanda zonyansa, ndi kukula kofanana.

Kuchuluka ndi kukula kwa ma aggregates omwe amagwiritsidwa ntchito mu kusakaniza kungakhudze kutuluka ndi kusanja katundu wa matope. Kuphatikizika kochulukira kungapangitse matope kukhala okhuthala kwambiri komanso ovuta kugwira nawo ntchito, pomwe kuphatikizika kochepa kumatha kupangitsa kuti matopewo akhale ofooka komanso osasunthika.

3. Zowonjezera zowonjezera zimagwiritsidwa ntchito mumatope odzipangira okha kuti apititse patsogolo ntchito ndi katundu wake. Pali mitundu ingapo ya zowonjezera zomwe zingagwiritsidwe ntchito, iliyonse ili ndi ntchito yake komanso zofunikira zake.

• Zochepetsera madzi: Zochepetsera madzi zimagwiritsidwa ntchito kuchepetsa kuchuluka kwa madzi ofunikira pakusakaniza, zomwe zingapangitse mphamvu ndi ntchito ya matope. Ziyenera kugwiritsidwa ntchito motsatira malangizo a wopanga ndipo zikhale zapamwamba kwambiri kuti zitsimikizire kuti zikugwira ntchito mosasinthasintha.
• Zolepheretsa: Zotsalira zimagwiritsidwa ntchito kuchepetsa nthawi yoyika matope, zomwe zingapereke nthawi yochuluka kuti matope azigwiritsidwa ntchito ndi kuwumbidwa. Ayenera kugwiritsidwa ntchito moyenera ndipo sayenera kusokoneza mphamvu kapena kulimba kwa matope.
• Plasticizers: Plasticizers amagwiritsidwa ntchito kupititsa patsogolo kayendedwe ka matope ndi ntchito, kuti zikhale zosavuta kutsanulira ndi kuchepetsa. Ayenera kugwiritsidwa ntchito moyenera ndipo sayenera kusokoneza nthawi kapena mphamvu ya matope.
• Kulimbitsa kwa Fiber: Kulimbitsa kwa Fiber kumatha kuwonjezeredwa kusakaniza kuti muchepetse mphamvu ndi kulimba kwa matope, kuchepetsa kusweka ndi kuwonongeka kwina. Mtundu ndi kuchuluka kwa fiber zomwe zimagwiritsidwa ntchito ziyenera kukhala zoyenera pakugwiritsa ntchito ndipo siziyenera kusokoneza kayendedwe ka matope.

Ponseponse, ntchito ndi zofunikira za zida zosiyanasiyana mumatope odziyimira pawokha opangidwa ndi gypsum ndizofunikira kuti mukwaniritse bwino ntchito ndi zotsatira zake. Posankha mosamala ndikuyika chilichonse chomwe mukusakaniza, mutha kupanga malo osalala komanso osalala omwe ali amphamvu, olimba, komanso oyenera ntchito yomwe mukufuna.
