Okokuqala, lapho uthenga amahange amakhemikhali, kufanele unake ikhwalithi yezinto.
Izikhonkwane zamakhemikhali ezisezingeni eliphakeme ngokuvamile zenziwe ngezinto zensimbi ye-alloy ephezulu, ezinobunzima obuphezulu nokumelana nokugqwala, futhi zingaqinisekisa ukuzinza nokuqina komkhiqizo.
Okwesibili, sidinga ukubheka ukuthi ukucaciswa nosayizi bamabholiti amakhemikhali ayisikhonkwane kuyahlangabezana yini nezidingo zangempela.
Lapho sikhetha ama-bolts amakhemikhali, sidinga ukunquma ubude bayo, ububanzi, umthamo wokuthwala umthwalo kanye neminye imingcele ngokuvumelana nezimo ezithile zephrojekthi ukuqinisekisa ukuthi umkhiqizo okhethiwe ungahlangabezana nezidingo zephrojekthi futhi ugweme isimo sokufakwa okuxekethile noma okungalungile. sebenzisa.
Ukwengeza, lapho uthenga amahange amakhemikhali, kufanele unake isitifiketi somkhiqizo nokuhlolwa.
Abakhiqizi abavamile bezikhonkwane zamakhemikhali ngokuvamile benza ukuhlolwa kwekhwalithi okuqinile kanye nezitifiketi emikhiqizweni yabo ukuze baqinisekise ukuthi imikhiqizo ihlangabezana namazinga ahambisanayo kanye nokucaciswa kwayo. Ngakho-ke, lapho uthenga, kufanele uqinisekise ukuthi umkhiqizo uphumelele yini ekuhlolweni kwe-ejensi efanele yezitifiketi, futhi unake isitifiketi sekhwalithi yomkhiqizo kanye nombiko wokuhlola ukuze uqinisekise ukuthi ikhwalithi nokusebenza komkhiqizo kuhlangabezana nezidingo ezijwayelekile.
Okokugcina, lapho uthenga amahange amakhemikhali, kufanele futhi ucabangele isevisi yangemuva kokuthengisa kanye nokwesekwa kobuchwepheshe bomkhiqizo.
Abakhiqizi bezihange zamakhemikhali ezisezingeni eliphezulu bavamise ukuhlinzeka ngesevisi ephelele yangemva kokuthengisa kanye nokwesekwa kobuchwepheshe, futhi bangaxazulula izinkinga ngokushesha ngesikhathi sokufakwa nokusetshenziswa kubasebenzisi ukuze baqinisekise ukusebenza okuvamile nokusetshenziswa okuphephile komkhiqizo. Ngakho-ke, ukuze kuqinisekiswe ukuthi ikhwalithi nokusebenza komkhiqizo kuqinisekisiwe ngempumelelo. Khetha FIXDEX
