Indlela ye-Anticorrosion yetanki yeoli

I-1, i-Anticorrosion yodonga lwangaphakathi lwetanki yeoli
Kukho ezi ntlobo zilandelayo zomhlwa kudonga lwangaphakathi lweitanki yeoli: i-corrosion ye-concentration, eyenzeka kakhulu ngaphantsi kwenqanaba lolwelo lodonga lwangaphakathi lwetanki yeoli, ngenxa yokwahlukana kwe-oksijini. I-Galvanic corrosion (i-electrochemical corrosion), eyona nto ibaluleke kakhulu kwaye iyingozi, iyenzeka kakhulu ezantsi, eludongeni nangaphezulu kwetanki. Ummandla we-anode kunye nommandla we-cathode we-electrochemical corrosion yenziwa ngenxa yokwahlukana okunokwenzeka okubangelwa yi-micro heterogeneity yezinto ngokwayo, ngelixa isizathu esona sizathu sokutshatyalaliswa kwe-electrochemical corrosion ngamanzi, ityuwa kunye ne-asidi equlethwe kwioli. Ukonakala okubangelwa yi-sulfate yokunciphisa iibhaktheriya kunye nezinye iibhaktheriya zenzeka ikakhulu emazantsi etanki. I-friction corrosion yenzeke ikakhulu kwindawo eyandayo yetanki yophahla oludadayo.

I-anti-static kunye ne-anti-corrosion coating efakwe kwi-tank yeemveliso zepetroleum yahluke kakhulu kwezinye iingubo zemizi-mveliso. Kufuneka ihlangabezane neemfuno ezimbini: okokuqala, ukongeza kwi-anti-static, kufuneka ibe nesakhono esihle sokulwa nomhlwa kwintsimbi; i-coating yangaphakathi yetanki igxininiswe kwimeko yeemveliso zepetroleum, kwaye imeko entywilisiweyo ikulungele ukungena kwi-corrosive medium ngokusebenzisa ifilimu yepeyinti kunye ne-corrosion yensimbi kunommandla we-atmospheric; okwesibini, Kufuneka imelane nokuntywiliselwa kweemveliso zepetroleum ixesha elide, kwaye musa ukungcolisa okanye kubangele ukuwohloka kweemveliso zepetroleum.

I-primer yenziwe nge-epoxy resin eguquliweyo, i-zinc powder kunye ne-agent esebenzayo yokunyanga. I-corrosion-resistant ngokusekelwe kumgaqo we-anode yombingelelo. Intsimbi ayinamhlwa ngokutshintshiselana nee-electron ezikhutshwe ngumgubo we-zinc. I-primer inokoma okukhawulezayo, ukunganyameki okugqwesileyo, ukusebenza okugqwesileyo kokumelana nomhlwa kunye nokuncamathela okuqinileyo. Ifanelekile kwindawo yefama yetanki. Ingubo ephezulu yeskimu yenziwe nge-resin ekhethekileyo, i-pigment ekhethekileyo kunye ne-filter conductive, enekhono elihle kakhulu le-antistatic kunye ne-anticorrosive.2, I-Anticorrosion yodonga lwangaphandle lwetanki yamafutha
Udonga lwangaphandle lweitanki yamafuthaikwimo engqongileyo yekhemikhali yomoya, kwaye olona hlobo lokuthotywa luyi-primary corrosion yebhetri, ekhaphukhaphu kunaleyo isetankini, kodwa ifuna ukumelana nemozulu okubalaseleyo. Ukongezelela, ubushushu bendalo betanki yeoli ye-anti-corrosion bunokuba nefuthe elibi kwimveliso. Umzekelo, amaqondo obushushu aphezulu ehlotyeni akulungele ukugcinwa kweemveliso ze-oyile ezibilayo, ngoko ke imilinganiselo yokugquma ubushushu kunye nokunciphisa ubushushu kufuneka ithathwe ukunciphisa ilahleko yeoli kunye nokuqinisekisa ukhuseleko lwemveliso.

Iskimu esicetyiswayo sokugquma ukugquma kodonga lwangaphandle lwetanki yeoli yile: epoxy Iron Red Antirust Primer (ibrashi okanye isitshizi 2-3 umaleko, ubukhulu 80-100 μ m) + epoxy micaceous ngentsimbi ephakathi umaleko (ibhrashi okanye fafaza 2-3 umaleko, ubukhulu 100-120 μ m) +2 ukugqiba ukugquma kwetanki yokutshisa okanye ukugquma kwe-thermal. iileya, ubukhulu 80-100 μ m). Kuba umphezulu sandblasted ofisitya soxinzelelo, i-epoxy zinc rich primer (ibrashi okanye isitshizi 2-3 umaleko, ubukhulu 80-100 μ m) ingasetyenziswa iDegree 80-100 μ m) ukuphucula impembelelo yokuchasana nokubola. I-Epoxy micaceous iron midcoat inefuthe elihle lokukhusela, kwaye inokudlala indima ehlala ikhusela kubunjineli bexesha elide lokuchasana nomhlwa. Itanki yokugquma i-tank inokunciphisa ubushushu be-oyile (xa kuthelekiswa naloo nto xa i-coating ingasetyenziswanga) ngo-7-10 ℃ ehlotyeni kunye nexesha lobushushu obuphezulu, kwaye inokumelana nemozulu ebalaseleyo kunye nesakhono sokuhombisa ukuchasana ne-corrosion, kwaye ifilimu yepeyinti ixhathisa ukutshiza ukhukuliseko lwamanzi.
