PPGI / prepainted galvanized simbi coil / sheet simbi denga mipumburu

Azvakanakira:

1.Anticorrosion durability

Iyo color coated plate ine mhedzisiro yegirazi coating. Kana iyo yakawedzerwa kune yekumanikidza roller mukugadzirwa kweplate yemavara, iyo inodzivirira firimu inonamira padhuze nepamusoro peplate, iyo isingakanganisi kukotama uye mamwe maitiro ekugadzirisa, asi zvakare inogona kuchengetedza ndiro pamusoro kubva mukukuvadzwa. mukugadzirisa nekuunganidza. Iko kunamatira kwepamusoro kwakasimba, uye kusimba kuri nani, uye hakuzove nekuputira, kuputika uye kutsemuka mushure mekushandisa kwenguva refu Kukanganisa kwakadai se spalling uye mamwe mahwendefa akapfapfaidzwa ehupfu ari nyore kuoneka, uye anogona kunyatso kudzora zvinoenderana ne zvinodiwa nevatengi.

2.Executive mwero

Iyo kambani yakapfuura IS09001, gbat24001, gba28001 quality certification, yakagadzwa uye yakavandudza seti yemhando yekusimbisa system. Pasi peseti yakakwana yemhando yekusimbisa sisitimu, kune nzira dzakakwana kubva pakurongeka kusvika pakugadzirwa uye kuendesa, uye zvinotevera zviyero zvinotevedzwa.

• GB / T 12754 ruvara rwakaputirwa simbi ndiro uye tambo
• JIS g3312 "pre coated hot dip galvanized steel sheet uye strip"
• TS EN 10169-1 inoenderera organic yakavharwa (coil yakavharwa) simbi zvigadzirwa zvesimbi Chikamu 1: general ruzivo (tsananguro, zvigadzirwa, kushivirira, nzira dzekuyedza)
• TS EN10169-2 "inoenderera organic coating (roll coating) simbi ndiro zvigadzirwa" Chikamu 2: Kuvaka kunze zvigadzirwa
• ASTM a755 "preated simbi mahwendefa ekushandiswa kwekunze muzvivakwa zvakavakirwa pane inopisa-dip simbi yakavharwa mahwendefa uye inogadzirwa ne roll coating process"

3.Substrate

Iyo ruvara yakavharwa substrate inonyanya kusanganisira inotonhora yakatenderedzwa pepa, galvanized sheet uye aluminized zinc sheet. Iyo pamusoro peinotonhora-yakakungurutswa substrate color coated sheet yakatsetseka uye ine yakanaka yekugadzirisa mashandiro, ayo akakodzera zvivakwa zvemukati kana midziyo yemumba. Mukuwedzera kune kupikisa kwakanaka kwehutu hwepamusoro pekuvhara, zinc coating inewo yakanaka anti-corrosion effect pa substrate, uye kudzivirirwa kwekucheka kwekucheka kuri nani kupfuura mamwe marudzi e substrates. Iyo yekuputira pamusoro peruvara yakashongedzwa bhodhi yakatsetseka uye yakanaka; Huremu hwe zinc layer hunogona kutariswa zvinoenderana nezvaunoda.

Tiye process flow

Ruvara rwakavharidzirwa simbi ndiro inowanzo galvanized simbi, GL mushure mekugadziriswa kwepamusoro panzvimbo yavo yakaputirwa nehumwe gobvu hwenamira yekunamatira kana dhizaini yeorganic film, mushure mekupopa, inova ndiro yeruvara, ine yakanakisa kusaora ngura, kuumbwa, kushongedzwa muchivako. , midziyo yemumba, indasitiri yemwenje, zvekufambisa uye mamwe maindasitiri anoshandiswa zvakanyanya seyakanaka inoumbwa zvinhu.
