Summary of the invention: the objective of the invention is the deficiency at above-mentioned technology, and provide a kind of concave convered glass that adopts silk screen printing and etching process to produce to people, its production method is simple, and pattern color is various, and semi-transparent half is bright, and stereoeffect is good.For achieving the above object, the technological method and the processing step of the present invention's employing are as described below:
(1) earlier sheet glass is cleaned up, carry out single face emulsification behind the airing;
(2) with the silk screen printing that designs pattern in advance of the sheet glass after the emulsification, printing-ink adopts corrosion-resistanting ink, back airing;
(3) sheet glass that is printed on pattern behind the airing is put in the etching tank that fills corrosive fluid and to be soaked 40-50 minute, the composition and the proportioning of corrosive fluid are prepared by weight percentage, water 36%--42%, sulfuric acid 15%--18%, hydrofluoric acid 43%--46%;
(4) will be set by step 3 sheet glass after handling put into tank and clean;
(5) sheet glass that will clean is put into sodium hydroxide tank immersion 30-60 second;
(6) will be set by step 5 sheet glass after handling put into tank flushing 30-60 second once more, thoroughly remove corrosion-resistanting ink;
(7) will further clean, dry by the concave convered glass after the above-mentioned 1-6 step processing, make finished product.
Characteristics of the present invention are that the making method science is simple, and are with short production cycle, save energy, and labor strength is low, has reduced production cost effectively.The concave convered glass that adopts this method to produce can pass through light post-absorption, refraction, projection and diffuse-reflectance, produces intensive color and stereoeffect.Have screening performance, its pattern semi-transparent half is bright, indistinct, but as the shield between two spaces, also be two bridges that the space couples together simultaneously, though intercepted sight line, but make people's vision as if can surmount this obstruct again, see many.Have the excellent decoration performance,, cooperate the light that changes to promote Space, make two dimensional surface visually have extremely strong stereoscopic perception, have abundant expressive force and artistic appeal simultaneously again for sheet glass has increased texture and stereoscopic sensation.
