黑白格遮蓋力板(ban)使用方法：
在測(ce)試涂(tu)料(liao)(liao)(liao)時需(xu)選(xuan)擇適當的(de)(de)(de)(de)面(mian)板(ban)(ban)(ban)(ban)(ban),通常線色涂(tu)料(liao)(liao)(liao)應用(yong)(yong)(yong)K=.008,深(shen)色涂(tu)料(liao)(liao)(liao)應用(yong)(yong)(yong)K=.004,將(jiang)(jiang)一滴涂(tu)料(liao)(liao)(liao)放(fang)在靠近底板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)分界處(chu),對(dui)線色涂(tu)料(liao)(liao)(liao)面(mian)板(ban)(ban)(ban)(ban)(ban)（K=.008）將(jiang)(jiang)帶(dai)支承腳(jiao)放(fang)在白(bai)區域的(de)(de)(de)(de)涂(tu)料(liao)(liao)(liao)上,用(yong)(yong)(yong)力壓緊(jin)面(mian)板(ban)(ban)(ban)(ban)(ban)致涂(tu)料(liao)(liao)(liao)打散,沒有(you)氣泡(pao)在面(mian)板(ban)(ban)(ban)(ban)(ban)之(zhi)間(jian)形(xing)成薄的(de)(de)(de)(de)楔形(xing),楔形(xing)將(jiang)(jiang)隨面(mian)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)移動而動,調節位移直到觀察黑白(bai)界線剛(gang)好消失,從(cong)黑板(ban)(ban)(ban)(ban)(ban)刻度上記下刻度讀數(shu),面(mian)板(ban)(ban)(ban)(ban)(ban)邊緣獲(huo)得(de)與底板(ban)(ban)(ban)(ban)(ban)相對(dui)應的(de)(de)(de)(de)系數(shu). 當測(ce)試深(shen)色涂(tu)時面(mian)板(ban)(ban)(ban)(ban)(ban)系數(shu)為(wei)K=.004,并從(cong)面(mian)板(ban)(ban)(ban)(ban)(ban)處(chu)讀取讀數(shu). 涂(tu)料(liao)(liao)(liao)厚度用(yong)(yong)(yong)毫米表(biao)示,黑和(he)白(bai)分界處(chu)所得(de)的(de)(de)(de)(de)讀數(shu)乘以所用(yong)(yong)(yong)面(mian)板(ban)(ban)(ban)(ban)(ban)楔形(xing)系數(shu)K,數(shu)值表(biao)示小涂(tu)膜厚度所需(xu)黑和(he)白(bai)的(de)(de)(de)(de). 涂(tu)層厚度所需(xu)遮蓋力或擴散力可直接從(cong)下面(mian)每(mei)個面(mian)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)轉換(huan)表(biao)中(zhong)獲(huo)得(de). 從(cong)m2/l換(huan)算平(ping)方(fang)英尺/加侖（英制）乘以49 ◇測(ce)試后(hou)需(xu)用(yong)(yong)(yong)適當的(de)(de)(de)(de)溶劑(ji)將(jiang)(jiang)兩塊板(ban)(ban)(ban)(ban)(ban)清(qing)洗干凈，不要將(jiang)(jiang)底板(ban)(ban)(ban)(ban)(ban)浸入強溶劑(ji)中(zhong)，以延長使用(yong)(yong)(yong)時間(jian)。
