Ta Yaya Injin Gwajin Abrasion Ke Aiki?

Gwajin gogewa na yau da kullun ya ƙunshi matakai masu zuwa:

1. Shirya Samfura

Ana yanke samfurin kayan aiki (misali, yadi, filastik, ko saman da aka fenti) zuwa ma'auni na daidaito. Wannan yana tabbatar da daidaito a duk gwaje-gwaje.

2. Shigar da Samfurin

An ɗaure samfurin da kyau a kan dandamalin mai gwajin. Ga masu gwajin juyawa kamar Taber Abraser, ana sanya samfurin a kan tebur mai juyawa.

3. Zaɓar Abubuwan da ke Shafawa

Ana zaɓar tayoyin da ke da abrasive, takardun yashi, ko kayan aikin gogewa bisa ga ƙa'idar gwaji (misali, ASTM, ISO). Waɗannan abubuwan suna amfani da gogayya mai sarrafawa ga samfurin.

4. Aiwatar da Load da Motsi

Injin yana amfani da takamaiman nauyin tsaye (misali, gram 500–1,000) ga abin da ke gogewa. A lokaci guda, samfurin yana yin motsi na juyawa, layi, ko juyawa, yana haifar da taɓawa mai maimaitawa.

5. Aiwatar da Zagaye
