Aqoonta Dahaarka ee Saxanka Birta Midabka Nadiif ah

Xoogga kuwa nadiifka ahsaxan bir midabkawaxay kuxirantahay alaabta iyo dhumucda substrate-ka, iyo cimri dhererku waxay kuxirantahay qadarka daahan zinc 318g / m2 iyo dhumucda dahaarka dusha sare.Dahaarku wuxuu leeyahay polyester, resin silicone, resin fluorine, iyo wixii la mid ah.Dhumucdiisuna waxay ka badan tahay 25um.Qaab dhismeedka dahaarka ayaa leh laba dahaar iyo hal qalajin, laba dahaar iyo laba qalajin, iwm.

Shuruudaha dahaarka midabka caadiga ah ee looxa nadiifka ah ayaa guud ahaan ka hooseeya kuwa darbiyada dibadda ah.Dahaarka sida caadiga ah loo isticmaalo saxan bir midabka waa polyester (PE), oo ay ku xigto silikoon modified resin (SMP), polyester cimilada u adkeysata sare (HDP), polyvinylidene vinylidene fluoride (PVDF), iwm. Qaab dhismeedka daahan ayaa loo qaybiyaa laba dahaarka mid qalajin iyo laba dahaar oo laba qalajin.Dhumucda dahaarka guud ahaan waa 20-25U dusha sare iyo 8-10U dhabarka.Isticmaalka dibadda ee dhismuhu waa inuusan ka yarayn 20U dusha sare iyo 10U dhabarka.

Astaamaha alaabta daahan:

1. Polyester (PE)

adhesion wanaagsan, kala duwan oo kala duwan ee qaabeynta iyo adkeysiga dibadda, caabbinta kiimikada waa dhexdhexaad.Nolosha adeeggu waa 7-10 sano.

2. Silicon modified resin (SMP)

Dahaarka ayaa leh qallafsanaan wanaagsan, caabbinta nabarka, caabbinta kulaylka, iyo sidoo kale adkeysi dibadeed oo wanaagsan, iyo sifooyin aan dhalaal lahayn.Haysashada dhaldhalaalka xaddidan iyo dabacsanaanta.Nolosha adeeggu waa 10-15 sano.

3. Polyester cimilada u adkeysata oo sareysa (HDP)

Iska caabin toosan oo UV ah oo heer sare ah, oo leh adkeysi sare, waxqabadkeeda ugu weyn ee u dhexeeya polyester iyo fluorocarbon.Nolosha adeeggu waa 10-12 sano

4. Polyvinylidene fluoride (PVDF)

Qaabaynta wanaagsan iyo ilaalinta midabka, adkeysiga dibadda ee aad u fiican iyo budada, caabbinta dareeraha, midab xaddidan.Nolosha adeeggu waa 20-25 sano.

5. Daaha-bakteeriyadu waxay ku daraysaa ions Ag ee daahan.

6. Dahaarka Antistatic wuxuu ku darayaa daahan elektrostatic conductive daahan.

Heerarka saxan bir ah oo midabaysan ayaa badanaa tixraaca waa ASTM A527 (galvanized), ASTM AT92 (aluminium zinc), Japan JIS G3302, Europe EN/0142, Korea KS D3506, Baosteel Q/bqb420.
