Opanga ufa wa latex opangidwanso amasanthula zomwe zimayambitsa ming'alu yamatope otsekemera

1. Kusakaniza kwamatope kosayenera

-

2. Mavuto amtundu wa simenti

Simenti ndi chinthu chofunikira chomangirira mumatope otsekera matenthedwe. Ngati mtundu wa simenti sukugwirizana ndi zofunikira, monga kusakwanira kwamphamvu, kusachita bwino kapena zonyansa zochulukirapo, zingayambitsekusamata bwino kwamatope komanso kusweka kosavuta. Njira ya hydration ya simenti imatsimikizira mphamvu ndi kukhazikika kwa matope, ndipo simenti yabwino kwambiri idzafulumizitsa maonekedwe a ming'alu.

3. Mphamvu ya kutentha ndi chinyezi

Kunja zachilengedwe zinthu zimakhudza kwambiri ntchito ya matenthedwe kutchinjiriza matope matope. Panthawi yomanga,kutentha kwambiri kapena kutsika kwambiri, chinyezi chambiri kapena chochepa kwambirizidzakhudza kuumitsa ndondomeko ya matope, potero kuwonjezera mwayi wa ming'alu. M'nyengo yotentha, madzi amasanduka nthunzi mofulumira kwambiri, zomwe zimapangitsa kuti matopewo achepetse ndi kupanga ming'alu; pamene kutentha kochepa, simenti hydration reaction ya matope ndi pang'onopang'ono, zomwe zidzakhudzanso mphamvu ya matope ndikuwonjezera kuthekera kwa ming'alu.

4. Kuchepa kwamatope

Thermal insulation mortar idzachepa mpaka pamlingo wina panthawi yowumitsa. Ngati ndikuchepa kwa matope ndi kwakukulu kwambiri ndipo sikusamalidwa panthawi yake, ming'alu imatha kupanga pamwamba. Makamaka mumatope ambiri kapena kumanga malo akuluakulu, shrinkage deformation ndi yaikulu, yomwe imakhala yosavuta kuyambitsa ming'alu. Choyambitsa cha shrinkage chikhoza kukhala chokhudzana ndi zinthu monga chiŵerengero chosayenera cha matope, chinyezi chochepa m'malo omanga, ndi kusamalidwa kokwanira.

6. Zomangamanga zosayenera

Tekinoloje yomanga ndi imodzi mwazinthu zofunika kwambiri pamtundu wa matope otsekemera otenthetsera. Njira zomangira zosayenera mongantchito zosagwirizana, makulidwe osiyanasiyana, kuthamanga kwambiri kapena kufulumira kwamangazidzachititsa kuchepa kosagwirizana kwa matope osanjikiza ndikupanga ming'alu. Kuonjezera apo, kusakaniza kosagwirizana kapena kusakaniza kwakukulu kwa matope kudzakhudzanso ntchito ya matope ndikuyambitsa ming'alu.

7. Mphamvu yakunja

Pambuyo pomanga matope opangira matenthedwe, mphamvu yakunja (mongakusintha kwa kutentha, kusintha kwa chinyezi, kumanga nyumba, etc.) angayambitsenso ming'alu. Makamaka pakukhazikika kwa nyumbayo, matope osanjikiza amatambasulidwa kapena kuponderezedwa, omwe amatha ming'alu.

8. Kugwetsa msanga kapena kusakonza bwino

Ntchito yomangayo ikamalizidwa, matope oteteza kutentha amayenera kusamalidwa bwino asanagwetse kuti matopewo akhale ndi madzi okwanira komanso olimba. Ngatichinyezi chokwanira kapena kuchiritsa nthawi saperekedwapanthawi yowumitsa, matope amachititsa kuti pamwamba pakhale kuuma ndi kusweka chifukwa cha kutaya madzi ochulukirapo. Kuonjezera apo, kuponyedwa msanga kapena zinthu zosayenera zakunja kungapangitsenso kupanga ming'alu pamtunda wamatope.

10. Chemical anachita

Nthawi zina, zowonjezera zomwe zimagwiritsidwa ntchito mu matope otsekemera zimatsutsana ndi zipangizo zina, zomwe zimapangitsa kusintha kwa thupi la matope, zomwe zingayambitse ming'alu. Mwachitsanzo, zigawo zina za mankhwala zimachita ndi simenti kuti zipange zinthu zowonjezera kapena zochepetsera, zomwe zimakhudza kuuma ndi kukhazikika kwa matope ndikuyambitsa ming'alu.

Mbadwo wa ming'alu mu matope otsekemera ndi zotsatira za kuphatikizika kwa zinthu zambiri, kuphatikizapozopangira chiŵerengero, njira yomanga, zinthu zachilengedwe, m'munsi mankhwala pamwamba, etc. Kuti muteteze bwino kubadwa kwa ming'alu, m'pofunika kulamulira mosamalitsa chiyanjano chilichonse panthawi yomanga, kusankha zipangizo zoyenera, kuonetsetsa kuti teknoloji yomangamanga yoyenera, ndikuwongolera moyenera malo omanga ndi kukonza zinthu. Kupyolera mu izi, zochitika za ming'alu zimatha kuchepetsedwa kwambiri ndipo ubwino ndi moyo wautumiki wa matope otsekemera otenthetsera amatha kusintha.
