ERICHSEN 耐擦洗試驗(yàn)機(jī)494 MC主要用于評(píng)估油漆

涂層的耐擦洗性

主要用于評(píng)估油漆

涂層的耐擦洗性. 測(cè)試參數(shù)可靈活設(shè)置也可用于客戶

特殊的測(cè)試用途如測(cè)試清潔劑等.

測(cè)試原理(摘錄原標(biāo)準(zhǔn))

a) Test in accordance with DIN 53 778- 2 *)

The scrub body is a defined pig bristle brush, which

is charged with 250 g. The washing fluid is

continuously fed by a micro dosing pump. Whether

the contamination has been removed or the coating

is scrubbed through to the substrate, will be

checked after an agreed number of scrubbing

cycles.

*) withdrawn, replaced by DIN EN ISO 11998

b) Test in accordance with ASTM D 2486

The scrub body is a defined nylon brush, which is

charged with 454 g. The washing liquid is applied

manually during the test at regular intervals and in a

defined amount. For sharpening the wear effect of

the scrubbing action, a narrow thin strip of metal

sheet will be placed centrally and transversely to

the stroke direction unter the foil. The test result is

the number of double strokes up to scrubbed

through to the substrate.

c) Test in accordance with DIN EN ISO 11 998

The scrubbing body is a defined type of abrasive

pad **) loaded with 135 g, which is moistened prior

to the test only once with a defined quantity of the

washing fluid. After scrubbing strain (200 double

strokes) the mass loss per unit area of the coating

and the average layer thickness loss will be

determined.

**) Abrasive pad "3M Scotch Brite, No. 7448" can be obtained

from the local dealer.

工作原理

儀器底部螺絲可調(diào)水平,上面裝有鋼槽用于測(cè)試. 兩

側(cè)配備樣品夾緊裝置.通過(guò)精密地步進(jìn)馬達(dá)和微處理

器確保運(yùn)行速度準(zhǔn)確可靠,具有的重復(fù)性.

可旋轉(zhuǎn)的摩擦刷固定架可以同時(shí)安裝3個(gè)摩擦刷,這

樣可以同時(shí)進(jìn)行3個(gè)測(cè)試.

通過(guò)按鍵和6位顯示屏進(jìn)行操作,具有以下功能:

- 控制行程 (啟動(dòng),停止,重置),

- 設(shè)置測(cè)試參數(shù) (摩擦速度, 路徑,摩擦次數(shù)),

- 可存儲(chǔ)最多20個(gè)測(cè)試程序。
