Kodi kusankha njerwa ng'anjo?

Ngakhale kupambana onse matekinoloje zosiyanasiyana zaposachedwapa, kunyumba kwa ambiri a m'dziko mwathu muno kupitiriza usavutike ntchito ng'anjo anachronistic. Komabe, mwa mawu a kudalirika ndi kuphweka mtundu wa magetsi akadali Palibenso, koma chifukwa munthu njira amenewa nthawi zambiri iyesedwa yolungama. Pa ntchito yomanga ng'anjo musaiwale kuti kutentha ng'anjo angafikire madigiri 800 Celsius.

Choncho sayenera kugwiritsidwa ntchito chifukwa njerwa wamba zomangamanga: chifukwa masitovu ikugwirizanirana bwino. More ayenera kugwiritsa ntchito fireclay refractory kapena mitundu yake. njerwa uwu wapangidwa makamaka wandiweyani dongo wofiira, anachotsedwa mu mode wapadera, koma chifukwa cha mlingo wa kukana kuti zinthu aukali zachilengedwe kwambiri kuposa mankhwala muyezo.

Pamene kuwayika mbaula, kulabadira chisanu kukana wa kugwiritsidwa ntchito ndi inu. Oddly okwanira, koma njerwa kilns uyenera kukhala khalidwe limeneli mokwanira. Makamaka izi ndi zoona mu nkhani kumene ng'anjo ili mu chipinda kuti usavutike kokha nthawi. N'chifukwa chake holide nyumba nyengo zabwino anamuyika masitovu ndi fireplaces njerwa fireclay. Iye sikuti refractories kwambiri, koma pafupifupi pasakhale ming'alu ngakhale mchikakamizo cha kusinthasintha lalikulu kutentha.

Mwazina, imasonyeza wokongola udzu-chikasu: ngati ng'anjo njerwa, zithunzi zimene Tingaone mu pepala mwangwiro zoyenera pafupifupi zokongoletsa aliyense ndi mipando ya nyumba. Tikumbukenso kuti pansi pa chivundikiro cha lacquer wapadera, amenenso pa-akuimira mu makampani, ndipo mukhoza kupeza moona zamatsenga kukongola tione.

Yomanga msika lero njerwa refractory kwa ng'anjo (zomwe ndi mtengo ndithu mkulu) kwake osiyanasiyana mwachilungamo lonse, koma m'lifupi mwa kusankha ayenera si mapeto akufa. Sankhani galimoto zambiri ntchito ndi mtundu: akuti sha-5 ndi akuti sha-8, Udzawaphimba zosowa za sing'anga-kakulidwe mbaula osoka pafupifupi milandu onse. Ngati ife kulankhula za kusiyana mitundu awiri awa, ang'ono: monga akuti sha-8 chingathe kupirira kutentha kwa madigiri 50 Celsius apamwamba nthawi zambiri, zilibe kanthu.

Komanso, fireclay njerwa kwa ng'anjo ndi yokulirapo kuposa ake "anzake" muyezo kukula, amene kwambiri facilitates ndondomeko kuika yokha, kwambiri mofulumira izo. Oona kwambiri chifukwa mtengo wa mtundu uwu wa zinthu zambiri amaluma. zofunika kwambiri kwapadera zojambula molondola njerwa ng'anjo. wofalitsa aliyense amadziwa kufunika kwa kulemekeza kufanana ndi evenness wangwiro zimfundo, atagona moto kapena mbaula.

Zofunika Mfundo yachiwiri ndi wapamwamba wa matope a. Makamaka, zowalamulira ayenera kuchitidwa ndi msoko makulidwe si zoposa zisanu millimeters, kotero kuti ntchito mosasamala pano ndi zosayenela. Mu ng'anjo kwambiri njerwa dongo aikidwa pa njira imene anawonjezera polimbikitsa kapena fireclay kusakaniza. Mpofunika ntchito GC-40 ndi GC 50 simenti, makhalidwe amene ali oyenera kwambiri zolinga zimenezi.
