Chiyambi cha kuponyera zokutira

Kuponyera zokutira ndi chinthu chothandizira chomwe chimakutidwa pamwamba pa nkhungu kapena pachimake, chomwe chimagwira ntchito yofunika kwambiri pakuwongolera mawonekedwe apamwamba a castings. Amisiri oyambirira aku China, zaka zoposa 3000 zapitazo, akonzekera ndikugwiritsa ntchito bwino zokutira, zomwe zimathandiza kwambiri pa chitukuko cha luso loponyera.

Ndi chitukuko cha kupanga ndi luso, zofunika kuponya khalidwe kukula tsiku ndi tsiku. Pofuna kupititsa patsogolo mpikisano wazinthu zawo, mabungwe ambiri amadzipereka ku kafukufuku wa zokutira chifukwa cha mavuto omwe amapanga.
Zotsatirazi, mwachidule za kuponyera ❖ kuyanika mavuto angapo.

Choyamba, okhutira okhutira ndi mphamvu ❖ kuyanika

Tsopano, zokutira zomwe zimagwiritsidwa ntchito popanga mchenga womangika utomoni zimafunikira kuti zikhale zolimba kwambiri komanso zolimba kwambiri, zomwe zimachitika makamaka paziganizo ziwiri.

1. Sinthani ku mawonekedwe a nkhungu yamchenga
Kale, dongo mchenga chonyowa mchenga mtundu osati utoto, utoto okha ntchito dongo mchenga youma mtundu. Chifukwa cha mphamvu ya dongo mchenga youma mtundu ndi otsika kwambiri, ndi kupanga castings ndi zofunika kapena lalikulu castings, chofunika ❖ kuyanika osati kupanga kudzipatula wosanjikiza, ndipo pamafunika kulowerera kuponyera ❖ kuyanika pamwamba zotsatirazi, bwino. kuphatikizira mchenga wa 3 ~ 4, pangani nkhungu pamwamba pake, chifukwa chake, kukhuthala kwa utoto sikungakhale kokwera kwambiri, zolimba sizokwera kwambiri.

2. Ganizirani zopulumutsa mphamvu, kuteteza chilengedwe komanso kuchepetsa ndalama zopangira
Zonyamulira zamadzimadzi zomwe zimagwiritsidwa ntchito popaka, makamaka madzi ndi mowa. 20 zaka 70 ~ 80 nthawi, anagwiritsa ntchito safuna kuti ziume kapena kuyatsa, akhoza volatilize chlorine m'badwo hydrocarbons, monga dichloromethane, monga chonyamulira utoto. Chifukwa cha kawopsedwe kake, kuwononga kwake chilengedwe pamene ukutuluka mumlengalenga, ndi kukwera mtengo kwake, tsopano sikukugwiritsidwa ntchito kwambiri.

Chachiwiri, zopangira ntchito ❖ kuyanika

Pali mitundu yambiri ya zida zomwe zimagwiritsidwa ntchito popaka zokutira, ndipo zidzawonjezeredwa nthawi zonse pamaziko a chitukuko cha mafakitale.

1. refractory aggregate
Refractory aggregate ndiye chigawo chachikulu cha zokutira, ndipo mtundu wake ndi kusankha kumakhudza kwambiri momwe amagwiritsira ntchito zokutira. Pa nthawi yomweyo, posankha aggregate, tiyeneranso kusanthula mwatsatanetsatane mu ukhondo mafakitale ndi chuma.

2. chonyamulira,
Zonyamulira zazikulu zomwe zimagwiritsidwa ntchito poyala zokutira ndi madzi, ma alcohols ndi ma hydrocarboni a chlorinated. Pakalipano, chifukwa cha kulingalira kwa mtengo ndi chilengedwe, chomwe chimagwiritsidwa ntchito kwambiri ku chlorine hydrocarbon monga chonyamulira cha zokutira, kawirikawiri ndi zokutira madzi ndi zokutira mowa.
