Ikhadi lobunikazi lamapayipi ensimbi angenamthungo isitifiketi sekhwalithi yomkhiqizo (MTC), eliqukethe usuku lokukhiqiza lwamapayipi ensimbi angenamthungo, okuqukethwe, ukwakheka kwamakhemikhali, inombolo ye-batch ye-batch yamapayipi, futhi angakwazi ukulandelela imininingwane yepayipi ngalinye. Lapho uthenga, imininingwane ye-MTC kumele ihambisane nophawu ngepayipi. Le yi-MTC efanelekile nehlelekile. Uyifundile?
