12.9 ibholiti yevili lelori yephosphated engwevu

Itekhnoloji yokwambathisa kumphezulu weziqhoboshi ezifana ne-U-bolts ibanda ngokubanzi, nto leyo enokukhokelela kwiimpawu zokugqwala emva kokusetyenziswa ngaphezu konyaka omnye.Emva kokugqwala, akuyi kuchaphazela kuphela inkangeleko kunye nenkangeleko, kodwa kwakhona kuchaphazela ukusebenza kwayo kunempembelelo enkulu ekusebenziseni izixhobo, ngoko ke ekusebenziseni kwethu, kufuneka sinikele ingqalelo kwezi meko zilandelayo ezisisiseko zokuthintela umhlwa.
Okokuqala, vumela umphezulu we-U-bolt wome kangangoko ukuze sikwazi ukuphepha okuninzi.
1. I-attachment yothuli okanye ezinye iincinci zezinto zetsimbi, emoyeni omanzi, amanzi aqhotyoshelweyo kunye nezikhonkwane zensimbi ezingenasici, zidibanise zombini zibe yibhetri encinci, ibangele ukusabela kokuziphatha kwe-electrochemical, kwaye ifilimu ekhuselayo yonakaliswe ngokulula, eyiyo. ebizwa ngokuba yi-electrochemical Analyse corrosion..
2. I-U-bolt yensimbi engenasici ine-adhesion kumphezulu we-organic juice, ngokungabikho kwamanzi kunye ne-oksijini ukwenza i-asidi ephilayo, i-asidi ye-organic i-corrosion ende phezu kwezinto zetsimbi.
3. Ukubambelela kwi-U-bolts yensimbi engenasici, i-alkali kunye netyuwa ecebileyo ibangela ukubola kwendawo yabafundi.
4. Komnye umoya ongcolisekileyo (ofana neatmosfera etyebileyo kwinani elikhulu leesulfides ezahlukeneyo, ii<em>carbon oxides, ii<em>nitrogen oxides kwilizwe lam), amanzi angaxutywanga abumba inqanaba lolwelo lwe<em>sulfuric acid, nitric acid, ne<em>acetic acid, ebangela abafundi ukuya kwi-chemistry ukubola kwesakhiwo.
