I-ASTM i-D7803-Standard yokuLungisa i-HDG yentsimbi yeengubo zomgubo

ASTM D7803

Iibhulorho ngomnye wemizekelo yeeprojekthi zokwakha ezidla ngokwakhiwa ngeentsimbi ezifakwe emanzini ashushu. Indlela yokugqoka le ntsimbi ngaphandle kokungaphumeleli kokubambelela kwenkqubo ye powder ichazwe kumgangatho omtsha we-ASTM.

Umgangatho omtsha, i-ASTM D7803, “Ukuziqhelanisa nokuLungisa iZinc (iHot-Dip Galvanized) yentsimbi egqunywe ngentsimbi kunye neMveliso yeNsimbi kunye neMiphezulu yeHardware Iingubo zePowder” igubungela ukulungiswa komphezulu kunye nokulungiswa kwe-thermal yentsimbi kunye neemveliso zentsimbi kunye ne-hardware engazange ipeyintwe okanye ifakwe umgubo ngaphambili (Qeqesha i-D6386). Umphezulu owenziwe ngegalvanized unokuthi uphathwe ngeengubo zokukhusela ukukhusela ukwenzeka kwebala lokugcina elimanzi. Lo mkhuba awusebenzi kwimveliso yentsimbi ye-galvanized okanye kwi-coil coil okanye iinkqubo eziqhubekayo zokugubungela i-roller.

"I-ASTM i-D7803 ichaza amanyathelo okufezekisa ukuthotyelwa kwe-powder powder phezu kwensimbi ene-galvanized ukuze kungabikho ukungaphumeleli kokubambelela kwi-powder system," kusho uThomas Langill, umlawuli wezobugcisa, i-American Galvanizers Association, kunye nelungu le-ASTM. "Kukho umdla owandisiweyo wokugquma ngomgubo kuba ingenazo iikhompawundi eziguquguqukayo zezinto eziphilayo ngaphezu kokukhuselwa komhlwa, njengokutyabeka ngegalvanized for. umbala kunye nenkangeleko.” ULangill uphawula ukuba i-D01.46 okwangoku ifuna ii-powder coaters kunye nabahloli ukuze babe negalelo kwimisebenzi yemigangatho eqhubekayo.

Umgangatho omtsha waphuhliswa yi-Subcommittee D01.46 kwi-Industrial Protective Coatings, inxalenye ye-ASTM International Committee ye-D01 kwi-Paint kunye ne-Related Coatings, izinto kunye nezicelo.
