美國RDS線棒涂布棒、刮墨棒
成立于1936年的美國R.D.SPECIALTIES RDS公司,是的線棒涂布棒生產(chǎn)商,RDS線棒,RDS刮棒,繞絲線棒,主要用于涂布規(guī)定厚度的濕膜,以測定試樣的遮蓋力、色澤或制備樣板等。采用 不銹鋼耐磨材質(zhì)制造,經(jīng)久耐用。非常適合涂布很薄涂層,如罐頭涂料及紙張涂料的試驗(yàn)。用于柔軟的材料如紙張﹑紙板﹑測試卡紙﹑箔紙﹑皮革﹑紡織品等效果好,用不同直徑的不銹鋼鋼絲纏繞在一定直徑和長度的不銹鋼鋼棒上,利用鋼絲之間的間隙制備不同厚度的涂膜。在油墨,涂料,粘膠和各種乳液的檢測中使用,用于研究,測試和質(zhì)量控制
RDS線棒使用原理:
RDS線棒適用于卡紙、塑料薄片、皮革、紡織品等各種柔軟基底表面通常不平整或有部分隆起,用一般的刮刀型涂膜器會產(chǎn)厚度不均的涂層。采用RDS線棒可解決這個(gè)問題。當(dāng)涂膜器在基底上拖動時(shí)會將基底碾壓平整。涂膜器上螺紋形成的溝槽用來產(chǎn)生厚度的膜。理論膜厚由螺紋間隙決定。涂膜器安裝在一個(gè)帶把手的支架上,耐腐蝕
涂層厚度主要分為三種:
RDS線棒理論濕膜厚度、實(shí)際濕膜厚度和干膜厚度
RDS線棒理論濕膜厚度即是涂膜器刃口到涂膜平面間矩。然而,當(dāng)涂膜器在基面上進(jìn)行涂膜時(shí),由于材料流動性和涂膜速度的 作用,膜層會產(chǎn)生一定的剪切現(xiàn)象,從而導(dǎo)致實(shí)際濕膜厚度比理認(rèn)值小(一般為理論值的60~70%,經(jīng)干燥后膜層體積縮涂膜棒小,干膜厚度約為實(shí)際濕膜厚度的40~50%)
使用棒型RDS線棒時(shí),如果儲料寬度較用于進(jìn)行涂膜的間隙(即涂膜器與基面存在間隙的部分)寬度寬涂膜層邊緣部分將比原期望值增加一個(gè)無法控制的增量,進(jìn)而給理論濕膜厚度帶來誤差。而ERICHSEN涂膜器消除了這種不度的根源。
RDS線棒尺參數(shù):
1.濕膜厚度: 14 um
2.線棒直徑:3/8"(9.4mm)
3.總長:16"(40cm)
4.涂布寬度:12"(30cm)
5.抓握部份:2 "×2"(5×5cm)

- 實(shí)際傳輸速率可能會有所不同從一個(gè)桿型(配置)到另一個(gè)
- 半鋼絲的尺寸從0.0025"到0.0165"
- 干涂層重量的計(jì)算假定為1.0g/cm3的涂布密度
- GSM = Grams per square Meter
- #/3000 = Lbs per 3000 square feet
- mil是長度單位,千分之一英寸,也就是1mil=0.001inch=0.0025cm=25um
- 一般歐美用英式單位mils來作為油漆膜厚單位是因?yàn)閙ils正好符合常規(guī)漆膜的范圍(1mil~10mil=25~250um),我國一般用標(biāo)準(zhǔn)的長度單位um微米來作為油漆膜厚單位
