Mzere wa Tungsten carbide umapangidwa makamaka ndi WC tungsten carbide ndi Cobalt ufa wosakanikirana ndi njira yachitsulo ndi pulverization, mphero ya mpira, kukanikiza ndi sintering, zigawo zikuluzikulu za aloyi ndi WC ndi Co, zomwe zili WC ndi Co mu ntchito zosiyanasiyana za tungsten carbide strip. sizili zofanana, ndipo kugwiritsa ntchito kwake kumakhala kwakukulu.
Chimodzi mwazinthu zopangira tungsten carbide, chimatchulidwa chifukwa cha mawonekedwe ake amakona anayi a mbale (kapena mabwalo), omwe amadziwikanso kuti tungsten carbide strip/plates. Mzere wa Tungsten carbide uli ndi kulimba kwambiri, kukana kuvala bwino, modulus yotanuka kwambiri, mphamvu yopondereza, kukhazikika kwamankhwala (acid, alkali, kutentha kwakuti oxidation kukana), kulimba kwamphamvu, kutsika kocheperako, kuchuluka kwamafuta ndi magetsi ofanana ndi chitsulo ndi mawonekedwe ake. aloyi.
Zifukwa zotanidesolderingndi zingwe za tungsten carbide? Chuangrui carbide adzayankha motsatira:
(1) Kuwotcha kwa tungsten carbide sikumangidwa mchenga kapena kupukutidwa musanayambe kuwotcherera, ndipo oxide wosanjikiza pamwamba pa brazing imachepetsa kunyowa kwachitsulo chowotcha ndikufooketsa mphamvu yomangirira ya weld.
(2)DesolderingZidzachitikanso pamene chitsulo chosungunula sichinasankhidwe ndikugwiritsidwa ntchito molakwika, mwachitsanzo, pamene borax ikugwiritsidwa ntchito ngati chitsulo chosungunula, borax silingathe kuchita bwino ntchito ya deoxidizing chifukwa borax imakhala ndi chinyezi chochuluka, ndipo zinthu zowonongeka sizikhoza kunyowa bwino. pa nkhope ya brazed, ndidesolderingzochitika zimachitika.
(3) Kutentha koyenera kwachitsulo kuyenera kukhala 30 ~ 50 °C pamwamba pa malo osungunuka achitsulo chowotcha, ndidesolderingzidzachitika ngati kutentha kuli kwakukulu kapena kotsika kwambiri. Kutentha kwambiri kungayambitse oxidation mu weld. Kugwiritsa ntchito chitsulo chokhala ndi zinc kumapatsa weld mtundu wabuluu kapena woyera. Pamene kutentha kwamoto kumakhala kotsika kwambiri, weld wandiweyani adzapangidwa, ndipo mkati mwa weld udzakutidwa ndi porosity ndi slag inclusions. Zomwe zili pamwambazi zidzachepetsa mphamvu ya weld, ndipo ndizosavuta kuzipanga ngati zakuthwa kapena kugwiritsidwa ntchito.
(4) Pakuwotcha, palibe kutulutsa kwa slag panthawi yake kapena kutulutsa kosakwanira kwa slag, kotero kuti slag yochulukirapo imakhalabe mu weld, yomwe imachepetsa mphamvu ya weld ndikuyambitsa.desoldering.
