Description
Technical field
The present invention relates to automation equipment field is and in particular to be used for producing the equipment of solid-state aqueouss sliver, particularly to
Highly effective energy-conserving environmental-protecting type doctor knife coater.
Background technology
Sliver paint, is also artificial grantie paint, granite mineral varnish, belong to novel pure Water-borne modification without any solvent-borne type material
Sand textured building coating.The solid-state aqueouss sliver manufactured by sliver paint is rich in the style of granite, granite
Intension, the noble quality of granite, the grade of granite, is the upgrading kind of traditional natural real stone paint.Big after spraying and decorating
Decorative pattern, big idea, good-looking, firm, the abundant texture of cruel image-stone material, give serious as natural granite, rough, air regarding
Feel and enjoy.The single uninteresting true mineral varnish of sand wall-like or other building coatings all lack the artistic strength of character of granite texture, all cannot
Compare favourably with the effect of granite paint.
At present in the technology of existing making solid-state aqueouss sliver, need by the separate processing step of multiple independences Lai complete
Become, including spraying, drying of heating, natural cooling and finished product feeding.Wherein, the production principle of spraying is all being moulded using artificial brushing
On flitch material（As PVC board）, will be wasted artificial in a large number by the way of artificial brushing, and to manually there being certain technique will
Ask, artificial production efficiency is relatively low, and the product thickness that artificial painting way is produced is uneven, and have aberration, produce
The quality of production of product is relatively low.Or sprayed on a plastic film with the mode of mechanically spraying, mechanically spraying materials are many, waste
Greatly, environmental pollution is serious, also can easily cause mutual pollution when multiple color chromatography sprays.Baking operation of heating is by room
Completing, its production technology is more original for outer dry in the sun or drying of heating, and dry in the sun takies the very big exterior space, and by weather etc. because
Element impact produces.In addition, traditional spraying process can cause the discharge of waste paint, cause environmental pollution serious, thus causing
Greatly waste.
