Aluminum wooden profile for sliding door
Aluminum wooden profile for sliding door , it’s popular for household user. We supply many designs for choice . People use aluminium wooden grain profile instead of pure wooden .
Wood grain transfer formula, often choose high and low hydroxyl value of two kinds of polyester. If the two hydroxyl value is too small, the gelling time difference, separation of coating and transfer paper is not easy. Through many experiments, we determined 75 mgKOH/g as a reference value of hydroxyl polyester resin hydroxyl, >75mgKOH/g high hydroxyl value, hydroxyl value < 75mgKOH/g is low, the film is easy to obtain and transfer separation this paper adopts polyester resin two range of hydroxyl value.
As the grain transfer printing has corrosion resistance, impact resistance, aging resistance, wear and tear, fire protection, outdoor use, 15 years without changing color and other properties, almost all products are produced in this way labels. For example, open the mobile phone shell, inside the cabinet you can see closely dotted with bar code labels. A lot of labels can stand the test of time, the long-term deformation, do not fade, not because of exposure to solvents will wear, not because of higher temperature on the deformation and discoloration, it is necessary to adopt a kind of special material printing medium and transfer grain material to ensure that these characteristics, general ink-jet, laser printing technology is unable to achieve.
