Kukhona abakhiqizi abaningi bezimpawu, uma ufuna ukwethembeka, ukukhiqizwa nokufakwa kusesezingeni eliphezulu, futhi izinyathelo zokuphepha zokwakha zisendaweni.Ngaleso sikhathi, uphawu lwenkampani lwalusenzima ukwenza, ingilazi egobile egobile, futhi amafreyimu aphansi ensimbi ayengenziwa ngokwezifiso, futhi imboni yezimpawu zengilazi yayingumkhiqizi wezimpawu, esetshenziselwa ukwenza izimpawu zenkampani enkulu yezentengiselwano, izimpawu zendawo yokuhlala, izimpawu zehhovisi, izimpawu zesibhedlela, izimpawu zezindawo zebhizinisi, izimpawu zesikole, izimpawu zesakhiwo samahhovisi, izimpawu zomnyango kamasipala.
Lonke ithimba labaklami labakhiqizi bezimpawu ohlelweni oluphelele nolwesayensi lokulawulwa kwekhwalithi yomkhiqizo ukuze amakhasimende ethu anikeze isethi ephelele yezixazululo zomklamo wesistimu yokuhlonza umkhiqizo.Kule nqubo yokukhiqiza insimbi yeshidi, abantu kufanele baqale benze umsebenzi omuhle wokulinganisa okujwayelekile kwempahla yensimbi, babambe imingcele ehlukahlukene yobuchwepheshe yempahla yeshidi lensimbi, futhi babale ukusetshenziswa kokuhlonza impahla noma izimpawu.Izinqubo zokwelashwa kwensimbi yeshidi zingase futhi zihlanganise ukulinganisa, ukupholisha kanye nokwelashwa kokushisa, ukususwa kukawoyela, ukuvimbela ukugqwala, njll. Kunezindlela ezimbili zokwelashwa: i-water plating kanye ne-double-layer vacuum thermal plating.
