PPGI / prepainted steel galvanized coil / sheet metal rolling rolls

Ainzuzo:

1.I-Anticorrosion ukuqina

Ipleyiti egqunywe ngombala inefuthe le-mirror coating. Xa yongezwa kwi-roller yoxinzelelo kwinkqubo yokuvelisa ipleyiti yombala, ifilimu ekhuselayo idityaniswe ngokusondeleyo kumphezulu wepleyiti, engachaphazeli nje ukugoba kunye nezinye iinkqubo zokucubungula, kodwa inokukhusela umphezulu wepleyiti kumonakalo. kwinkqubo yokucubungula kunye nokuhlanganisa. Ukunamathela komphezulu kunamandla, kwaye ukuqina kubhetele, kwaye akuyi kubakho i-shelling, ukuqhekeka kunye nokuqhekeka emva kokusetyenziswa kwexesha elide Iziphene ezifana ne-spalling kunye nezinye iipleyiti ezitshiziweyo zomgubo zibonakala zibonakala, kwaye zinokulawulwa ngokungqongqo ngokuhambelana ne iimfuno zabathengi.

2.Umgangatho olawulayo

Inkampani iphumelele i-IS09001, i-gbat24001, i-gba28001 isiqinisekiso somgangatho, yasekwa kwaye yaphucula isethi yenkqubo yokuqinisekisa umgangatho. Ngaphantsi kwesethi epheleleyo yenkqubo yokuqinisekisa umgangatho, kukho iinkqubo ezipheleleyo ukusuka kwi-oda ukuya kwimveliso kunye nokuhanjiswa, kwaye le migangatho ilandelayo iphunyezwe ngokungqongqo.

• I-GB / T 12754 ipleyiti yentsimbi efakwe umbala kunye nomcu
• I-JIS g3312 "yayigqunywe ngaphambili eshushu idiphu yentsimbi kunye nomcu"
• I-TS EN 10169-1 iimveliso zentsimbi eziqhubekekayo (coil coil coated) Icandelo le-1: Ulwazi ngokubanzi (iinkcazelo, izixhobo, ukunyamezela, iindlela zovavanyo)
• I-EN 10169-2 "imveliso eqhubekayo ye-organic organic (i-roll coating) iimveliso zeplate yentsimbi" Icandelo le-2: Ukwakhiwa kweemveliso zangaphandle
• I-ASTM a755 "iipleyiti zentsimbi eziqatywe ngaphambili ukuze zisetyenziswe ngaphandle kwizakhiwo ezisekwe kwiipleyiti zetsimbi ezishushu ezidiphu kwaye ziveliswe ngenkqubo yokwambathisa"

3.ISubstrate

I-substrate egqunywe ngombala ibandakanya ishidi eliqengqelekayo elibandayo, iphepha elenziwe ngamazinki kunye ne-zinc sheet. Umphezulu we-substrate yombala obandayo owenziwe ngombala ugudileyo kwaye unomsebenzi omhle wokucubungula, ofanelekileyo kwizakhiwo zangaphakathi okanye izixhobo zendlu. Ukongeza kwi-corrosion resistance resistance, i-coating ye-zinc nayo ine-anti-corrosion effect kwi-substrate, kwaye ukukhuselwa komgca wokusika kungcono kunezinye iintlobo ze-substrates. Umphezulu wokugquma webhodi egqunywe ngombala ugudile kwaye umhle; Ubunzima be-zinc layer bunokumiselwa ngokweemfuno zakho.

Tuqhuba ukuhamba

Ipleyiti yentsimbi egqunywe ngombala idla ngokuba yintsimbi ekhandisiweyo, iGL emva konyango lomphezulu kumphezulu ogqunywe ngobunzima obuthile bokuncamathelisa okanye umaleko wefilimu ephilayo, emva kokunyanga, ibe yipleyiti yombala, enokumelana nokugqwesa okugqwesileyo, ukubumba, ukuhombisa kwisakhiwo. , izixhobo zasekhaya, ishishini lokukhanya, ezothutho kunye namanye amashishini asetyenziswa ngokubanzi njengemathiriyeli efanelekileyo edibeneyo.
