Njira zothetsera zolakwika zophatikizidwa

* Chidziwitso champhamvu:

Pali zoonekeratu malo, chipika ndi mizere zolakwika pamwamba pa zitsulo mbale.Pambuyo pa annealing, zidzawoneka zoyera kapena zakuda.Pazifukwa zazikulu, kuyabwa pamwamba, zolakwika zosakhazikika komanso zolakwika zosagwirizana ndi concave-convex zimawonekera.Ndikosavuta kuweruza kuphatikizikako ndi peeling, koma ndikosavuta kusokonezedwa pakuzindikira kuphatikizika kwa mizere yapang'ono komanso kukanda pamwamba.Chiweruzo kusiyana kwakukulu uku ndi kuvulala kwa Ge kumakhala kokhazikika, yunifolomu, m'lifupi ndi yopapatiza kwambiri;Kuphatikizika kwa mizere sikokhazikika, kosagwirizana, kufalikira.Kapena kupyolera pamwamba akupera, zikande pamwamba kuya sikudzakhala zakuya, akupera akhoza kuthetsedwa, ndi kuphatikizika ndi chakuya, pambuyo pamwamba akupera, padzakhala kuya kutambasuka.

 

 

*Kusanthula chifukwa:

Kuphatikizikako kumayamba chifukwa cha zitsulo zopanda zitsulo zomwe zimapangidwira mosalekeza, zomwe zimayamba kukhalapo pansi pa khungu la billet, ndipo zimawonekera pamtunda pambuyo pa kugudubuza kotentha ndi kuzizira.Chifukwa cha kukhalapo kwa mafuta ndi makutidwe ndi okosijeni ndi zonyansa zina pamwamba pa mbale yolimba yokulungidwa, zophatikizika sizidziwikiratu, ndipo zimatha kuwululidwa momveka bwino pambuyo pa annealing.

*Njira zochizira:

1) Konzani zitsanzo, jambulani zithunzi ndikuzijambulitsa, ndi kulemba ndemanga zabwino panjira yomaliza mbali imodzi

2) Chotsani zolakwika zomwe zapezeka musanayambe kumaliza ntchito yomaliza

3) Pambuyo pa annealing, zofooka zazing'ono zomwe zapezeka zidzawonongeka ndi ntchito yokonza ndi kukonza
