Ndodo Yowotcherera ya Chitsulo Chosapanga Dzimbiri ya ER385
Kufotokozera Kwachidule:
ER385 ndi mtundu wa chitsulo chodzaza zitsulo, makamaka electrode yachitsulo chosapanga dzimbiri. “ER” imayimira “Electrode kapena Ndodo,” ndipo “385″ imasonyeza kapangidwe ka mankhwala ndi makhalidwe a chitsulo chodzaza zitsulo. Pankhaniyi, ER385 yapangidwira kuwotcherera zitsulo zosapanga dzimbiri za austenitic.
Ndodo Yowotcherera ya ER385:
Zitsulo zosapanga dzimbiri za Austenitic, monga Type 904L, zimakhala ndi chromium yambiri, nickel, ndi molybdenum, zomwe zimapangitsa kuti zisawonongeke kwambiri komanso zikhale zoyenera kugwiritsidwa ntchito m'malo ovuta. Ndodo zolumikizira za ER385 zimagwiritsidwa ntchito kwambiri m'malo omwe kukana dzimbiri ndikofunikira kwambiri, monga m'mafakitale a mankhwala, petrochemical, ndi m'madzi. Ndodo zolumikizira za ER385 ndizoyenera kugwiritsa ntchito njira zosiyanasiyana zolumikizira, kuphatikizapo kulumikiza zitsulo zotetezedwa (SMAW), kulumikiza zitsulo zolumikizidwa ndi gasi (GTAW kapena TIG), ndi kulumikiza zitsulo zolumikizidwa ndi gasi (GMAW kapena MIG).

Chifukwa Chiyani Sankhani Ife?
•Mukhoza kupeza zinthu zabwino kwambiri malinga ndi zomwe mukufuna pamtengo wotsika kwambiri.
•Timaperekanso mitengo yotumizira katundu (Reworks, FOB, CFR, CIF, ndi yotsika mtengo). Tikukulimbikitsani kuti mugule katundu woti mutumize katunduyo, zomwe zingakuthandizeni kukhala ndi ndalama zochepa.
•Zipangizo zomwe timapereka ndi zotsimikizika kwathunthu, kuyambira pa satifiketi yoyesera zinthu zopangira mpaka chiganizo chomaliza. (Malipoti adzawonetsedwa pakufunika)
•Tikutsimikizira kuti tipereka yankho mkati mwa maola 24 (nthawi zambiri mu ola lomwelo)
•Perekani lipoti la SGS TUV.
•Tadzipereka kwathunthu kwa makasitomala athu. Ngati sizingatheke kukwaniritsa zofunikira zanu mutafufuza njira zonse, sitidzakusokeretsani polonjeza zinthu zabodza zomwe zingapangitse ubale wabwino ndi makasitomala.
•Perekani chithandizo chokhazikika.

Kodi mawonekedwe a waya wowotcherera wa ER385 ndi otani?
1. Kukana dzimbiri bwino kwambiri, kumatha kukana dzimbiri la sulfuric acid ndi phosphoric acid, kumatha kukana dzimbiri la acetic acid kutentha kulikonse komanso kuchuluka kwake pansi pa kupanikizika kwabwinobwino, ndipo kumatha kuthetsa bwino dzimbiri la dzenje, dzimbiri la dzenje, dzimbiri la m'ming'alu, dzimbiri la kupsinjika ndi mavuto ena a halides.
2. Chipilalacho ndi chofewa komanso chokhazikika, chopanda madzi ambiri, mawonekedwe okongola, chochotsa matope bwino, chogwiritsa ntchito waya mokhazikika, komanso chogwira ntchito bwino kwambiri pakuwotcherera.
Malo osokerera ndi zinthu zofunika:
1. Gwiritsani ntchito zotchinga zosagwedezeka ndi mphepo powotcherera m'malo omwe mphepo imawomba kuti mupewe mabowo ophulika chifukwa cha mphepo yamphamvu.
2. Kutentha pakati pa ma pass kumayendetsedwa pa 16-100℃.
3. Chinyezi, dzimbiri, ndi madontho a mafuta pamwamba pa chitsulo choyambira ziyenera kuchotsedwa kwathunthu musanagwiritse ntchito.
4. Gwiritsani ntchito mpweya wa CO2 powotcherera, kuyera kuyenera kukhala kopitilira 99.8%, ndipo kuyenda kwa mpweya kuyenera kuyendetsedwa pa 20-25L/min.
5. Kutalika kwa waya wowotcherera kuyenera kulamulidwa mkati mwa 15-25mm.
6. Mukatsegula waya wolumikizira, chonde dziwani izi: chitanipo kanthu kuti isanyowetsedwe ndi chinyezi, igwiritseni ntchito mwachangu, ndipo musasiye waya wosagwiritsidwa ntchito ukuwonekera mlengalenga kwa nthawi yayitali.
