Kodi chiboliboli cha njerwa ndi chiyani?

Zomalizira izi zimapangidwa ndipadera zomwe zimatchedwa refractory clay. Pa kutentha kwa dongosolo la 1100 ° C limakhala lofanana kwambiri ndipo mphamvu zake ndizodzikweza kwambiri, zomwe zimapangitsa kuti zitheke.

Chotsatira chake, mumapeza zinthu zothetsera fala ndi mafunde akuluakulu, kutentha kwa madzi, kutulutsa phokoso labwino komanso kusunga kutentha. Njerwa yotchedwa facade yokongola ndi yabwino chifukwa imatha kutsukidwa kuchokera ku payipi ndikusakanizidwa ndi maburashi. Anapeza ntchito yake osati kumapeto kwa makoma a nyumbayo, akugwiritsanso ntchito poika zipilala, kukongoletsa malo pansi pa mawindo, pali mitundu yapadera yopangira njira ndi zitsulo.

Njerwa yamoto imakhala pamalo ake ngakhale kumalo okongoletsera malo. Njira za njerwa iyi, yomwe ili ndi mthunzi wabwino, imakongoletsedwa ndi minda yamaluwa, nyengo za chilimwe ndi malo ang'onoang'ono kutsogolo kwa nyumbayo. Zomangamanga zomwe zaperekedwa zimalandira kutchuka chifukwa cha kuyanjana kwa chilengedwe. Zapangidwa ndi dothi, palibe zoipitsa zina zofunikira, chifukwa kutentha kwakukulu kumagwira ntchito.

Kujambula njerwa

Monga mukudziwira, ngakhale zomwe zimapindulitsa kwambiri pazinthu zowonjezera ndi zofunikira nthawizina sizikukondwera ndi wogula chifukwa cha zikhalidwe zawo zosadziwika. Pankhaniyi, njerwa zazingwe zimatha kukwaniritsa zofuna za mthengi aliyense.

Chowonadi ndi chakuti ngakhale mndandanda woyandikana nawo awiri udzakhala wosiyana pang'ono kuchokera kwa wina ndi mzake kwa semitones angapo. Izi zikugwiritsidwa ntchito pa njerwa zofiira. Kawirikawiri, zosankha za monochrome zimasankhidwa kuti amalize malo akuluakulu.
2. Njerwa zamtundu wachikulire zowirira zakale zofiira zofiira zimaphatikizidwa ndi njira zachikhalidwe. Mthunzi wonyezimira wokalamba wokalamba kumadera onse, ndipo pansi pa malo amodzi pafupi ndiwindo kapena pamphepete mwa nyumbayo muli kowala kwambiri.
3. Zitsanzo zabwino zimagwira ntchito zosiyanasiyana. Njerwa za keramic zachitsulo zamtundu uwu zimakhala zooneka ngati zovuta zochitika kapena mbali zina za falayi kuti apange mawonekedwe odabwitsa.
4. Matabwa a nkhuni pansi pa njerwa zakale ndi zomwe zimatchedwa kuti melange zotsatira zimapezeka chifukwa chapadera kuponyera, pamene malo a chitsulo chosayidi amagwiritsidwa ntchito kusintha pang'ono mtundu wake kukhala wakuda. Zotsatira zake, zimakhala zofiira ndi zofiira zofiira kapena zofiira zofiira.
5. Choyambirira cha matabwa a clinker oyera ndi njerwa ina iliyonse imapezeka ndi otchedwa glazing.

Zotsatira zake, pa kutentha pamwamba pake ndizopangira utoto, zomwe zimapereka zotsatira zotere ndikusunga mtundu kwa nthawi yaitali.

Ngati njerwa ya Clinker siimayambitsa mavuto, ndiye kuti ndi njira yothetsera komanso yothetsera zipangizo zamakono, chirichonse chiri chovuta. Chosakanizacho chikhale chokhazikika, ndipo lembani zitsulo ziyenera kukhala zogwedeza ndi tile. Ngati muwonjezera pa izi mtengo wa zakuthupizi, ndizomveka kuika ntchito kwa mbuyeyo.
