Njerwa - ndi yokumba mwala lomwe lili ndi mawonekedwe zonse, zokhudzana ndi zipangizo yomanga. Iye ndi zosagwira moto, cholimba ndi cholimba, amagwiritsidwa ntchito kawirikawiri pomanga nyumba mzinda, mipanda ndi outbuildings osiyanasiyana m'banja. The makulidwe a linga la njerwa angakhale osiyana, izo zonse zimadalira zimene mtundu zakuthupi inu nsanamira khoma limodzi, awiri kapena imodzi ndi theka. Ambiri ndi ceramic ndi calcium silicate njerwa.

Ceramic njerwa nthawi zambiri ntchito maziko ake, kumanga mpanda, kubala makoma, wosakwatira ndi nyumba Mipikisano storey. Adzaze dziko voids mu konkire ziwembu monolithic. Komanso njerwa ceramic kufalitsa banja ndi mafakitale ovens. Kukumana ceramic njerwa Ubwino wa zodalirika, maonekedwe kwambiri, kumukakamiza makulidwe. Njerwa makoma ndi kapangidwe osiyana ndi zosiyanasiyana mitundu. Izo ntchito osati kwa nyumba yatsopano, komanso ntchito ya kukonzanso. Komanso, ntchito kapangidwe mkati.

Ceramic njerwa Ubwino:

• Mphamvu ndi zonyamula chisanu.

• Kumveka katundu kutchinjiriza.

• Zachilengedwe wochezeka (zikhale za dongo, amene Mwachibadwa zopangira, musati zimatulutsa zinthu zoipa pa ntchito).

Ngati mufuna kukhala zomveka bwino kutchinjiriza, makulidwe a makoma a njerwa akhale oyenerera. Muyenera kugwiritsa ntchito awiri njerwa ndi masovedwe.

The kuipa njerwa ceramic akhoza zimachitika motere:

• Mtengo gulu.

• Pamene Anaika mpanda wa nkhaniyi ndi anthu amaganiza kuti ndalama zina kwa njira khalidwe.

• Kuti akukumana khoma la njerwa anali mzungu, ndi kugula zinthu zonse yomweyo.

Laimu njerwa amapangidwa kuchokera madzi, laimu mpweya ndi khwatsi mchenga. Alandire pa kuthamanga zimalimbikitsa nthunzi pa kutentha madigiri 200 Celsius. Ngati utoto ceramic mwa kusakaniza mitundu yosiyanasiyana ya dongo, njerwa silicate akhoza utoto yekha mothandizidwa ndi zipangizo zina zapadera amene ali ndi chiyambi yokumba. Ubwino wa njerwa silicate zotsatirazi:

• Zachilengedwe wochezeka.

• Kwambiri phokoso kutchinjiriza.

• kachulukidwe apamwamba (poyerekeza ndi njerwa ceramic).

• Mphamvu ndi dzuwa.

• A assortment lalikulu la mitundu ndi mawonekedwe.

Chimodzi mwa zovuta ndi otsika silika njerwa madzi kukana. Nkhanizi nyumba si abwino ntchito pomanga maziko, umene mosalekeza poyera kuti madzi. Komanso, musati ntchito njerwa laimu kwa chimneys ndi masitovu, monga sangaime kutentha.

Monga tanenera kale pamwambapa, mbeta, limodzi ndi theka ndi awiri njerwa anatsimikiza ndi makulidwe a linga. Njerwa mukhoza kuyamba osati ofunda ndi zimatenga phokoso, koma nyumba chokongoletsedwa, limene kwa zaka zambiri adzasangalala eni.
