Chofunikira Choyesa

Mayeso osalala

Machubu achitsulo okhala ndi m'mimba mwake wamkulu kuposa 22 mm mpaka 400 mm, ndi makulidwe a khoma kuposa 10 mm ayenera kuyezetsa kupendeketsa. Pambuyo sampuli ndi flatten

Mayeso opindika

Machubu achitsulo okhala ndi m'mimba mwake osapitirira 22 mm ayenera kuyesedwa. Mbali yopindika ndi 90o. Radiyo yopindika ndi nthawi ya 6 yakunja kwa chubu chachitsulo. Pambuyo popinda chitsanzo, palibe ming'alu kapena ming'alu yomwe imaloledwa kuwonekera pa chitsanzo.

Kuyeza kwa macroscopic

Kwa machubu achitsulo opangidwa mwachindunji ndi ma billets kapena zitsulo zachitsulo mosalekeza, woperekayo akuyenera kutsimikizira kuti palibe mawanga oyera, zonyansa, thovu lamlengalenga, zigamba zachigaza kapena kusanjika pamtundu wa asidi wowotcha macroscopic minofu ya billet kapena chubu chachitsulo.

Kuwunika kosawononga
