Kungani ama-bollard ensimbi engagqwali eba mnyama?

Amabhodi ensimbi engagqwalingokuvamile azigqwali ngoba izingxenye zazo eziyinhloko ziqukethe i-chromium, ephendula ngamakhemikhali nomoya-mpilo ukuze yakhe ungqimba oluqinile lwe-chromium oxide, oluthi

kuvimbela ukugqwala okwengeziwe kwensimbi futhi ngaleyo ndlela inokumelana okunamandla kokugqwala. Lolu ngqimba oluqinile lwe-chromium oxide lungavikela ubuso bensimbi engagqwali ezindaweni eziningi zemvelo

ukuguguleka komhlabathi, okwenza kube yinto elwa nokugqwala.

Kodwa-ke, ukufiphazwa kobuso bensimbi engagqwali kungase kwenzeke ngaphansi kwezimo ezithile. Izizathu eziyinhloko zokufiphazwa kobuso bensimbi engagqwaliamabhodi ensimbi engagqwalikungenzeka:

Izinto ezingcolisa ubuso:Uma ubuso bensimbi engagqwali buvezwa noma bubekwe izinto ezingcolisayo isikhathi eside, njengothuli, ukungcola, amafutha, njll., kungase kwakheke ungqimba lokungcola, okubangela

ubuso bube mnyama.

Ukufakwa kwe-oxide:Kwezinye izindawo ezikhethekile, ubuso bensimbi engagqwali bungase bube ngaphansi kokubekwa kwama-oxide athile, njengokugqwala noma amanye ama-oxide ensimbi, okungadala

ubuso bube mnyama.

Ukusabela kwamakhemikhali:Ngaphansi kwesenzo samakhemikhali athile, ukusabela kwamakhemikhali kungase kwenzeke ebusweni bensimbi engagqwali, okubangela ukuba ubuso bube mnyama. Isibonelo, ukusabela

kungenzeka ngemva kokuthintana nezinto ezinezakhiwo zamakhemikhali ezinamandla njenge-asidi nama-alkali.

Indawo yokushisa okuphezulu:Endaweni yokushisa okuphezulu, ukushiswa kwe-oxidation kungenzeka ebusweni bensimbi engagqwali, okubangela ukuthi ubuso bube mnyama.

Ngobaamabhodi ensimbi engagqwali, ukuhlanza nokulungisa njalo kubaluleke kakhulu. Ungasebenzisa insipho ethambile nendwangu ethambile ukususa ukungcola namafutha ebusweni. Ngaphezu kwalokho,

uma usebenzisaamabhodi ensimbi engagqwaliezindaweni ezikhethekile, kufanele kuqashelwe ukugwema ukuthintana namakhemikhali nokugcina indawo yomile futhi ihlanzekile ukuze kwandiswe impilo yenkonzo ye-

amabhodi ensimbi engagqwali.
