Ruvara rwakavharwa simbi coil, inozivikanwawo seruvara simbi ndiro muindasitiri. Colour coated simbi coils zvigadzirwa zvinogadzirwa kubva kutonhora-akakungurutswa simbi mahwendefa uye galvanized simbi coils se substrates, iyo inoitiswa pamusoro (degreasing, kucheneswa, makemikari kutendeuka kurapwa), zvinoramba zvakaputirwa nejasi (roll coating method), uye zvino kubikwa nekutonhodzwa. . Mahwendefa esimbi akavharwa akareruka, anoyevedza anoyevedza, uye ane kunaka kwekusagadzikana. Zvinogona zvakare kugadziriswa zvakananga, zvichipa rudzi rutsva rwezvigadzirwa zvemaindasitiri akadai sekuvaka, kuvaka ngarava, kugadzira mota, midziyo yemumba, uye engineering yemagetsi. Vakawana migumisiro yakanaka yakadai sokutsiva huni nesimbi, kuvaka kunobudirira, kuchengetedza simba, uye kudzivirira kusvibiswa.
Nzira yekugadzira:
Iwo makuru ekugadzira maitiro eakajairwa maviri ekuputira uye maviri kuomesa anoenderera eruvara coating unit ndeaya:
Uncoiler -> Muchina wekusonesa -> Pressure roller -> Stretching muchina -> Uncoiler sleeve -> Alkali washing and degreasing -> Kuchenesa -> Kuomesa -> Passivation -> Kuomesa -> Yekutanga kupfekedza -> Yekutanga kuomesa -> Topcoat chaiyo yekupfeka - > Kuomesa bhachi -> Kutonhora kwemhepo -> Coiling sleeve -> Coiling muchina -> (Pazasi roll yakaputirwa uye zvakachengetwa).
Kushandiswa Kwechigadzirwa:
Ruvara rwakavharwa ndiro yesimbi inoshandisa galvanized steel plate se substrate, kuwedzera kune zinc dziviriro, ine organic coating pazinc layer inovhara nekuparadzanisa ndiro yesimbi, kudzivirira kuita ngura. Hupenyu hwesevhisi hwayo hwakareba kupfuura iyo yendiro yesimbi, uye zvinoshumwa kuti hupenyu hwebasa resimbi yakavharwa ndiro yakareba 50% kupfuura iyo yendiro yesimbi. Nekudaro, munzvimbo dzakasiyana nenzvimbo dzekushandisa, hupenyu hwesevhisi hwemapuleti akaiswa mavara ane huwandu hwakafanana hwekuvhenekera, kupfekedzwa kwakafanana, uye ukobvu hwakafanana hwekuputira huchasiyana zvakanyanya. Semuenzaniso, munzvimbo dzemaindasitiri kana nharaunda dzemahombekombe, chiyero chekuora chinowedzera uye hupenyu hwebasa hunokanganiswa nekuda kwekuita kwesulfure dioxide gasi kana munyu mumhepo. Munguva yekunaya kwemvura, kana iyo yakanyungudutswa mumvura inonaya kwenguva yakareba kana munzvimbo umo kusiyana kwekushisa pakati pemasikati neusiku kwakanyanya uye kunowanzoita condensation, ichakurumidza kuora uye hupenyu hwebasa huchaderedzwa. Zvivako kana mafekitari akagadzirwa nemarata ane mavara akavharidzirwa kazhinji ane upenyu hurefu hwebasa kana akukurwa nemvura inonaya, zvikasadaro kushandiswa kwazvo kungakanganiswa nezvinokonzereswa nesarufa dioxide gasi, munyu, uye huruva. Naizvozvo, mukugadzira, iyo yakakura kurerekera kwedenga, kashoma kuti iunganidze guruva nezvimwe zvinosvibisa, uye iyo yakareba hupenyu hwebasa; Kune nzvimbo kana zvikamu zvisingawanzoshambidzwa nemvura inonaya, zvinofanira kugara zvichigezwa nemvura.
Mahwendefa esimbi ane mavara anoshandiswa zvakanyanya. Iine yakanakisa yemamiriro ekunze kuramba, corrosion resistance, uye yakakwirira kugadzirisa zvivakwa. Marata esimbi emavara anoshandiswa zvakanyanya mukuvaka, midziyo yemumba, chekufambisa, kurongedza, kugadzira michina, kushongedza kwemukati, zvekurapa, indasitiri yemotokari, nezvimwe.
Hunhu hwakanaka:
1. Kubudirira kwehupfumi
Maitiro ekugadzira emavara akavharidzirwa simbi mahwendefa ane mashoma enjodzi dzezvakatipoteredza uye anogona kudzokororwa, zvichideredza zvakanyanya kusvibiswa kune zvakatipoteredza. Uyezve, vane huremu huremu, hunogona kuchengetedza zvinhu zvezvivakwa zvinotakura uye kuderedza mutengo.
