2) process hpe hkang na matu galaw ai lam ni
Chemical degreasing galaw ai lam a yaw shada ai lam gaw, dai arung arai a ntsa na sau hpe shaw kau nna, n-gun yawm mat na matu hkyen lajang na matu re. tank liquid a madung arung arai ni gaw, n-gun yawm mat ai tsi (powder) nga ai, dai hta n-gun n rawng ai tsi (powder) hpe n-gun n rawng ai (powder) n-gun yawm ai, tank liquid temperature, n-gun yawm ai aten, hte dai zawn re ai ni hpe n-gun jaw ai.
Hka htung hpe shinggyin la ai lam a yaw shada ai lam gaw, n-gun n-gun hpe yeng seng kau na matu, hka shin na matu ra ai arung arai gaw, hydrochloric acid rai nna, madung hkang zing ai ladat parameters ni gaw, hydrochloric acid n-gun, pickling aten hte n-gun n-gun hpe n-gun n-gun n-gun n-gun.} ni rai nga ai.
