    • PURPOSE: A liquid etchant using fluoride salt instead of hydrofluoric acid is provided to give uniform evenness on the surface for low reflection, prevent scratches, and decrease danger in processing and environmental pollution. CONSTITUTION: The liquid etchant comprises the components of: 0.5-50wt.% of fluoride salt such as NH4F, NH4HF2, NaF, NaHF2, KF or KHF2; 5-40wt.% of surfactants such as dioctyl sulfosuccinate or R1R2R3R4N+X-, wherein R1, R2, R3 and R4 are C1-C30 alkyl or aryl, X is F, Cl, Br, I, or carboxylic acid anion of C1-C10, such as stearyl dimethyl benzyl ammonium chloride, stearyl trimethyl ammonium chloride, etc; 0.05-10wt.% of sulfate of Ca, Na, K, Mg or Ba; and 0.5-10wt.% of oligosaccharide containing monosaccharide(glucose, fructose) and disaccharide(cane sugar, lactose). The low reflective glass is produced by soaking glass in prepared etchant or spraying etchant over glass.
    • 目的:提供使用氟化物盐代替氢氟酸的液体蚀刻剂,以在表面上均匀均匀,低反射,防止划伤,降低加工和环境污染的危险。 构成:液体蚀刻剂包括:0.5-50重量%的氟化物盐如NH 4 F,NH 4 HF 2,NaF,NaHF 2,KF或KHF 2的组分; 5-40重量%的表面活性剂如二辛基磺基琥珀酸盐或R1R2R3R4N + X-,其中R1,R2,R3和R4是C1-C30烷基或芳基,X是F,Cl,Br,I或羧酸阴离子C1- C10,如硬脂基二甲基苄基氯化铵,硬脂基三甲基氯化铵等; 0.05〜10重量%的Ca,Na,K,Mg或Ba的硫酸盐; 和0.5-10重量%的含寡糖(葡萄糖,果糖)和二糖(蔗糖,乳糖)。 低反射玻璃是通过将玻璃浸在预制的蚀刻剂中或在玻璃上喷涂蚀刻剂来生产的。
