KUEDZA NZIRA KUTI KUSVIRA POWDER

Nzira dzekuedza dzakagadzirirwa zvinangwa zviviri: 1. Kuvimbika kwekuita; 2. Kudzora kwehutano

(1) GLOSS TEST (ASTM D523)

Muedzo wakavharwa flat panel neGardener 60 degree mita. Coating haifanire kusiyana + kana - 5% kubva kune data sheet zvinodiwa pane chimwe nechimwe chinhu chinopihwa.

(2) BENDING TEST (ASTM D522)

Coating on .036 inch gobvu phosphated simbi panel achamira 180 madhigirii kukotama pamusoro 1/4″ mandrel. Hapana kupenga kana kurasikirwa kwekunamatira uye kupera pakubhenda kugona kubviswa ne3M Y-9239 tepi.

(3) HARDNESS TEST (ASTM D3363)

Faber Castell huni mapenzura anoshandiswa mukuoma kwe1,2,3,4,. Coating hairatidze mamakisi kubva ku2H penzura.

 (4) CROSS HATCH ADHESION TEST (ASTM D3359)

Nyora parallel mitsetse kuburikidza nekuputira kune substrate, 1/4 ″ kureba pamusoro pechinhambwe cheinji imwe. Nyora imwe seti ye parallel mitsetse 1/4 ″ kure uye perpendicular kune yekutanga seti. Isa chero tepi inonamira wobvisa zvishoma nezvishoma. Mhedzisiro haifanirwe kunge iri kusimudza hupfu hwakapora pakati pemitsara yevanyori.

(5) CHEMICAL RESISTANCE TEST (ASTM D1308)

Isa angangoita madonhwe gumi e test solvent, ine 10% nehuremu toluene uye 95% nehuremu Methal Ethyl Keytone pamusoro peiyo coating. Bvumira kumira kwemasekonzi makumi matatu. Pukuta nemucheka wakapfava, wakaoma. Coating haifanire kuratidza kadiki denderedzwa chiratidzo.

(6) IMPACT TEST (ASTM D2794)

Coating on .036 inch thick phosphated steel panel ichamira ne 1/2 ″ Gadheni impact tester bhora pa 26 inch pound yakananga nekudzokera kumashure. Hapana kufura kana kurasikirwa kwekunamatira. Pedzisa haizokwanisi kubviswa panzvimbo yekubata ne 3M Y-9239 tepi.

(7) KUYEDZA KUNONGA KWEMUNYU (ASTM B117)

Shandisa 5% munyu munyu pa 92-97 madhigirii F mune yakavharwa weather cabinet. Nyora X musimbi zinc phosphated test panel kusvika kusimbi isina chinhu. Ongorora maawa makumi maviri nemana ega ega. Kupedzisa bvunzo uye maawa akazara mushure me24/1 ″ creepage kubva munzvimbo yakanyorwa. Creepage haifanire kudarika 4/1 ″ mune chero nzira kubva kumutsara wevanyori mushure me4 maawa kuratidzwa.
