Ukuthetha ngeempompo zenkqubo yeekhemikhali, zisetyenziswa ngokubanzi ngakumbi kwimveliso yemveliso, ngakumbi kwintsimi yeekhemikhali, iimpompo zenkqubo yeekhemikhali ezinganyangekiyo zidlala indima ebalulekileyo. Kwiimeko eziqhelekileyo, ngenxa yobume bendawo apho iimpompo zenkqubo yeekhemikhali zisetyenziswa, ngokuqhelekileyo zenziwe ngetsimbi okanye i-fluoroF46. Kwizimbiwa eziqhelekileyo, ulwakhiwo lwazo luthambekele kakhulu kwi-corrosion, kunye nokusingqongileyo kwangaphandle okufana nobushushu, ukufuma kunye nomoya Kuya kukhokelela ngokuthe ngqo kwintsimbi yesinyithi, ngoko ke izinto zethu eziqhelekileyo kwiimpompo zenkqubo yeekhemikhali ezichasene ne-corrosion ziyinsimbi engenasici kunye ne-fluoroplastic F46.

Umgangatho ophakathi olungele iimpompo zenkqubo yeekhemikhali ngokusisiseko uyonakalisa, kwaye kuhlelo lokubola, kukho iindlela ezimbini zokuhlela ngokubanzi.

I-mechanical ihlelwa, kwaye enye ihlelwa ngokwesizathu kunye nokubonakala kokubola. Ngokwendlela ye-corrosion, inokwahlulwa ibe yi-electrochemical corrosion kunye ne-chemical corrosion. I-Electrochemical corrosion ibhekisela ikakhulu kwi-phenomenon ye-corrosion ebangelwa ukusabela kwe-electrode kumphezulu wezinto zetsimbi emva kokuba idibene nesisombululo se-electrolyte. Oku kusabela ngokuqhelekileyo kukusabela kwe-redox, kwaye izinto eziphambili kukufuma kunye nobushushu bokusingqongileyo; Ukonakala kweekhemikhali kubhekiselele kwisenzo sekhemikhali esinamandla ngokwentelekiso phakathi komphezulu wesinyithi kunye nendawo ejikelezileyo, ebangela ukuba isinyithi sonakaliswe ukusa kumlinganiselo othile. Ezona zizathu zolu mhlwa bubushushu obuphezulu kunye nendawo eyomileyo. Ngokwenkangeleko kunye nezizathu zomhlwa, inokohlulwa ibe yi-peeling corrosion, i-industrial atmospheric corrosion, iqondo lobushushu obuphezulu be-oxidation corrosion kunye ne-marine atmospheric corrosion.

Kwimekobume enongcoliseko olunzulu lwemizi-mveliso, kuba kukho izinto eziguquguqukayo ezinje ngesulfide, ikharbon diokside kunye nehydroxide emoyeni, kwaye ikwaqulethe uthuli lwemizi-mveliso, ezi ziimidiya ekulula ukubangela umhlwa. Xa la majelo eendaba ekwimekobume efumileyo, irhasi yeasidi iya kudibana namanzi yenze iiasidi ezingaphiliyo. Ezi asidi zineepropati ezomeleleyo ezonakalisayo, ngoko ke ziya kubangela umhlwa. Kwimekobume yendawo yoshishino, izixhobo zibangelwa yimpembelelo edibeneyo ye-electrochemical corrosion kunye ne-corrosion ngqo yeekhemikhali. Undoqo wayo yonke i-corrosion yinkqubo ye-oxidation apho izinto zetsimbi zilahlekelwa yi-electrons ukwenza i-ion. Umahluko ophambili phakathi kwe-electrochemical corrosion kunye ne-industrial atmospheric corrosion yimimandla eyahlukeneyo apho zenzeka khona.

I-corrosion yezixhobo ihambelana ngokusondeleyo nezixhobo zezixhobo. Kwinkqubo yokukhetha izinto zemichiza, kufuneka sigxininise kwisenzeko sokubola, sinikele ingqalelo ekukhethweni okufanelekileyo kwezinto, kwaye siqwalasele ngokupheleleyo iipropati ze-medium, iqondo lokushisa lokusingqongileyo kunye noxinzelelo lokusebenza, njl. ishishini lemichiza Iimfuno zemathiriyeli ekrwada kunye nesakhiwo kunye nodidi lwezixhobo zoyilo. Uyilo lwesakhiwo kufuneka lugxininise kwiimfuno zemveliso kunye neempawu zoxinzelelo kwimveliso kunye nokusebenza kwezixhobo zemichiza, kwaye le miba ilandelayo kufuneka ithathelwe ingqalelo kuyilo: okokuqala, iimfuno zesakhiwo semveliso kufuneka zihambelane ne-corrosion. iimfuno zokuxhathisa ukuveliswa kweemveliso zeekhemikhali; okwesibini Kuyimfuneko ukunikela ingqalelo ekusebenzeni uzinzo kunye nokugudiswa kwezixhobo zemichiza, ukuthintela ukunqunyanyiswa kweendaba ezitshabalalisayo, ukusabalalisa ngokungalingani komthwalo wobushushu, ukuxinwa komphunga kunye nokuqokelela kweemveliso zokubola; ekugqibeleni, kuyimfuneko ukunikela ingqalelo ekukhuselweni kwemikhosi yangaphandle ukuthintela Ukukhathala ukubola okubangelwa kukutshintshana koxinzelelo.
