Uma ukuphindaphindwa kwemiphumela yokulinganisa kukubi noma kunedatha engajwayelekile, imbangela kufanele itholakale ngesikhathi futhi isilinganiso kufanele siphindwe.

6. Isiphetho
Inani le-pH lama-silicone hip pads lingenye yezinkomba ezibalulekile zokulinganisa ikhwalithi yalo. Ukulinganisa ngokunembile inani le-pH kubaluleke kakhulu ukuqinisekisa ikhwalithi yomkhiqizo nokuvikela impilo nokuphepha kwabasebenzisi. Njengamanje, izindlela ezivame ukusetshenziswa zokulinganisa inani le-pH lama-silicone hip pads zifaka phakathi indlela yokucwiliswa emanzini, indlela ye-acid-base titration, indlela yephepha lokuhlola i-pH kanye nendlela ye-potentiometric titration, njll. Indlela ngayinye inezinzuzo nezinkinga zayo. Ekusetshenzisweni okusebenzayo, indlela efanele kufanele ikhethwe ngokuya ngesimo esithile. Ngesikhathi senqubo yokulinganisa, kufanele kuqashelwe ukulawula izici ezahlukahlukene ezithinta imiphumela yokulinganisa, ukulandela ngokuqinile izindlela ezijwayelekile kanye nemininingwane yokusebenza ukuqinisekisa ukunemba nokuthembeka kwemiphumela yokulinganisa. Kubathengi bamazwe ngamazwe abathengisa ngobuningi, ukuqonda nokuqonda kahle indlela yokulinganisa kanye namaphuzu okulawula ikhwalithi yama-silicone hip pads kuzosiza ekwenzeni izinqumo ezinolwazi ngesikhathi senqubo yokuthenga, ukukhetha imikhiqizo ehlangabezana nezidingo zekhwalithi, ukuhlangabezana nesidingo semakethe kanye nokuphumelela emakethe yamazwe ngamazwe encintisana kakhulu.
