12.9 ibholidi yesondo leloli elimpunga

Ubuchwepheshe bokumboza ebusweni bezinsimbi ezifana nama-U-bolts ngokuvamile bubanda, okungaholela ezimpawu zokugqwala ngemva kokusetshenziswa isikhathi esingaphezu konyaka ongu-1.Uma sekugqwalile, ngeke kuthinte ukubukeka nokubukeka kuphela, kodwa futhi kuthinte ukusebenza kwayo kunomthelela omkhulu ekusetshenzisweni kwemishini, ngakho-ke ekusetshenzisweni kwethu, kufanele sinake lezi zimo eziyisisekelo ezilandelayo ukuvimbela ukugqwala.
Okokuqala, vumela ubuso be-U-bolt bome ngangokunokwenzeka ukuze sikwazi ukugwema okuningi.
1. Okunamathiselwe kothuli noma ezinye izinhlayiya zensimbi, emoyeni onomswakama, amanzi ajiyilethi anamathiselwe nezikulufu zensimbi engagqwali, kuxhuma kokubili ibhethri elincane, elicupha ukusabela kokuziphatha kwe-electrochemical, futhi ifilimu yokuvikela ilimala kalula kakhulu, ebizwa nge-electrochemical Analyze corrosion..
2. I-U-bolt yensimbi engagqwali ine-adhesion ebusweni bejusi ephilayo, lapho kungabikho amanzi kanye ne-oksijeni ukuze kwakhiwe i-asidi ephilayo, i-asidi ephilayo iwukugqwala okude ebusweni bensimbi.
3. Ukunamathela kwama-U-bolt ensimbi engagqwali, izindawo ezine-alkali nezinosawoti ezinothe kubangela ukugqwala kwabafundi bendawo.
4. Komunye umoya ongcolile (njengokungathi umkhathi ucebile ngenani elikhulu lama-sulfide ahlukene, ama-carbon oxides, ama-nitrogen oxides ezweni lami), amanzi angancibilikisiwe akha iphoyinti eliwuketshezi le-sulfuric acid, i-nitric acid, ne-acetic acid, okubangela abafundi. ukugqwala kwesakhiwo samakhemikhali.
