I-ASTM D7803-Ejwayelekile Yokulungiselela insimbi ye-HDG yezimbotshana eziyimpuphu

I-ASTM D7803

Amabhuloho ayisibonelo esisodwa samaphrojekthi wokwakha avame ukwakhiwa ngezinsimbi ezishisayo zediphu. Indlela yokugqoka le nsimbi ngaphandle kokwehluleka ukunamathela kwesistimu ye-powder kuchazwe kuzinga elisha le-ASTM.

Izinga elisha, i-ASTM D7803, “Ukuzijwayeza Ukulungiselela I-Zinc (Hot-Dip Galvanized) Coated Iron and Steel Product kanye ne-Hardware Surfaces Amakhava wePowder” ihlanganisa ukulungiswa kwendawo kanye nokulungiswa okushisayo kwemikhiqizo yensimbi neyensimbi kanye nezingxenyekazi zekhompiyutha ezingapendiwe noma zifakwe impushana ngaphambilini (Practice D6386). Izindawo ezinothayela kungenzeka zilashwe ngezingubo zokuzivikela ukuze kuvinjelwe ukwenzeka kwebala elimanzi lokugcina. Lo mkhuba awusebenzi emikhiqizweni yensimbi enamashidi noma kumakhoyili enamathela noma ezinqubweni eziqhubekayo zokumboza ama-roller.

"I-ASTM D7803 ichaza izinyathelo zokufeza ukunamathela kwe-powder coating phezu kwensimbi eyakhiwe ngakho-ke kungabikho ukwehluleka kokunamathela kwesistimu ye-powder," kusho uThomas Langill, umqondisi wezobuchwepheshe, i-American Galvanizers Association, kanye nelungu le-ASTM. “Kube nentshisekelo eyengeziwe ekufakweni kwempushana njengoba ingenawo ama-organic compounds aguquguqukayo ngaphezu kokuvikela ukugqwala, njengokumbozwa kukathayela. umbala nokubukeka.” ULangill uphawula ukuthi i-D01.46 njengamanje ifuna ama-powder coater nabahloli ukuze bafake isandla emisebenzini yamazinga eqhubekayo.

Izinga elisha lakhiwe Ikomidi Elingaphansi D01.46 le-Industrial Protective Coatings, ingxenye ye-ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications.
