Insimbi engagqwaliiwumkhiqizo ogoqiwe owenziwe ngensimbi engagqwali, onezinto ezinhle kakhulu ezifana nokumelana nokugqwala, ukumelana nokushisa okuphezulu, nokumelana nokugqoka. Amakhoyili ensimbi engagqwali asetshenziswa kakhulu ekwakheni, ifenisha, i-kitchenware, izinto zikagesi, izimoto, imikhumbi kanye neminye imikhakha.
Izinto eziyinhloko zamakhoyili ensimbi engagqwali zihlanganisa amamaki ahlukene ensimbi engagqwali njenge-201, 304, 316, njll. Into ngayinye inokwakheka kwamakhemikhali okuhlukile nezici zokusebenza. Isibonelo, amakhoyili ensimbi engagqwali angu-304 anokumelana nokugqwala okuhle nokucutshungulwa, futhi avame ukusetshenziselwa ukwenza i-kitchenware, ifenisha, njll.; Amakhoyili ensimbi engagqwali angu-316 anokumelana nokugqwala okuphezulu nokumelana nokushisa okuphezulu, futhi afanele imishini yamakhemikhali, izindawo zasolwandle, njll.
Ukwelashwa okungaphezulu kwamakhoyili ensimbi engagqwali kuhlanganisa izinqubo ezahlukene ezifana ne-2B, BA, NO.4, njll. Izindlela ezihlukene zokwelashwa kwendawo zingakhethwa kuye ngezidingo ezahlukene. Ngaphezu kwalokho, amakhoyili ensimbi engagqwali nawo angasikwa, apholishwe, adwetshwe futhi acutshungulwe ngokwezidingo zamakhasimende ukuze ahlangabezane nezidingo ezithile zokusebenzisa.
