Z275 Ruvara Yakavharwa PPGI/PPGL Simbi Coil/Matare Embavha Masheets

Azvakanakira:

1.Anticorrosion durability

Iyo color coated plate ine mhedzisiro yegirazi coating. Kana ichiwedzerwa kune inodzvinyirira roller mukugadzirwa kweplate yemavara, firimu rekudzivirira rinonyanya kubatanidzwa nepamusoro peplate, iyo isingakanganisi kukotama uye mamwe maitiro ekugadzirisa, asiwo inogona kuchengetedza ndiro yepamusoro kubva pakukuvadzwa mukugadzirisa uye kusangana. Iko kunamatira kwepamusoro kwakasimba, uye kusimba kuri nani, uye hakuzovi nekuputika, kuputika uye kuputika mushure mekushandisa kwenguva refu Kukanganisa kwakadai se spalling uye mamwe mahwendefa akapfapfaidzwa ehupfu zviri nyore kuoneka, uye zvinogona kunyatsodzorwa maererano nezvinodiwa 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 rwakavharwa simbi ndiro kazhinji isimbi yakabatiswa, GL mushure mekugadziriswa pamusoro penzvimbo yavo yakavharwa nehumwe ukobvu hwenamira yekunamira kana layer ye organic firimu, mushure mekurapa, inova ndiro yeruvara, ine yakanakisa kusakara, kuumba, kushongedzwa muchivako, midziyo yemumba, indasitiri yemwenje, yekufambisa uye mamwe maindasitiri anoshandiswa zvakanyanya sechinhu chakanakira composite.
