Rudzi rwakavharwa coil inoumbwa nejasi repamusoro, primer, coating, substrate uye kumashure pendi.
Pedza pendi:dzivirira zuva, kudzivirira kukuvadza kwe ultraviolet kumucheka;Kana iyo yekupedzisira yasvika pahukobvu hwakatarwa, inogona kugadzira dense yekudzivirira firimu, ichidzikisa kupenya kwemvura uye oksijeni.
Primer:zvinobatsira kusimbisa kusungirirwa kwe substrate, kuitira kuti kupera kwepende hakusi nyore kuitika mushure mokunge firimu yakanyungudutswa nemvura, uye ichavandudzawo kurwisana kwehutu, nokuti iyo primer ine corrosion inhibitor pigments, yakadai sechromate pigments; kuitira kuti anode ipfuure uye kuramba kwecorrosion kugadziridzwe.
Coating:kazhinji galvanized kana aluminium zinc plating, chikamu ichi chehupenyu hwesevhisi chechigadzirwa chine kukanganisa kukuru, iko kukora kwacho ndiko, zvirinani kuramba kwecorrosion.
Substrate:kazhinji kwendiro inotonhora yakakungurutswa, simba rakasiyana rinotarisa michina yemavara yakavharwa ndiro inogona kutakura.
Pendi yekumashure:basa nderekudzivirira kukora kwesimbi ndiro kubva mukati, kazhinji zvidimbu zviviri zvechimiro (2/1M kana 2/2, primer + musana pendi), kana kumashure kuchida kusungwa, zvinokurudzirwa kushandisa imwechete layer (2/1).
Ruvara rwakavharwa nesimbi coil corrosion process:
Dulling coating, coating color coating, powder coating, cracking furo coating, chena/tsvuku — - - - - mumutsara wekucheka unopepeta ngura - cut - coating area off — - - - - nzvimbo hombe ye ngura, local red ngura - ndiro – corrosion perforation plate kukundikana.
Nzira yekukundikana kweplate yesimbi yakagadzirwa nemavara inoratidzwa mumufananidzo uri pamusoro.Coating kutadza, kutadza kuvhara uye kupera kwesimbi ndiro ndiwo akakosha ekuora maitiro.Naizvozvo, kuwedzera ukobvu hwekuputira uye kushandisa mamiriro ekunze uye corrosion resistant coating ndiyo inonyanya kushanda nzira yekudzivirira kusaora kwemavara akavharwa simbi ndiro.
