From Hangzhou car galvanized steel exquisite imitation copper door, non-standard door, the first IS9001-2008 certification, Zhejiang Hang Sheng Door Co., Ltd. is the large domestic imitation copper doors and non-standard door production enterprises, its first-class design, strong technology Strength and unique technology to win the praise of users in China's imitation copper doors and non-standard door field play an increasingly important role.
Imitation copper door surface why easy to fade, easy to paint it? Mainly because of the problem of weather resistance did not solve. At present, the surface treatment process of imitation copper door is mainly composed of "transfer", "metal paint", "plastic powder direct coloring" and a few special processes, and the general process of transfer process are: polyether epoxy plastic foundation - Drying - transfer - tearing, grinding - dust - cover - dry, it is easy to fade, out of paint in the outdoors more, because the outdoor is the natural conditions of exposure or wind and frost rain and snow erosion, so ask us In the timber to be targeted.
1, polyether epoxy plastic powder is the characteristics of low cost, better off the good tear paper, but in the case of light will soon powder;
2, transfer paper is in the paper as a carrier, printed with ink up, and then through its easy to migrate the characteristics of a certain temperature transfer to the top of the plastic foundation, the ink is directly related to the color of the fade fast speed;
3, varnish play aesthetics, increase the feel and added value and the role of protection, but now the use of ordinary steel doors and windows are not resistant to UV light function.
Comprehensive above, epoxy plastic foundation → ordinary transfer paper → ordinary indoor varnish is caused by easy to fall paint, easy to fade the main reason. Ordinary Varnish does not absorb ultraviolet light or reflect the role of ultraviolet light, so the UV light can directly penetrate the varnish to reach the plastic powder surface caused by powder powder, transfer paper fade. And so on, after the powder powder powder as the carrier of the above has not, so the varnish off.
To solve this problem can be used: polyester outdoor powder → outdoor transfer paper → ordinary varnish can solve the paint time, on this basis and then use high weather fastness can be more effective solution to paint and transfer paper fade Problem, but the drawback of this process is the high cost of polyester resin, transfer difficult, tearing difficult, easy to polish, the efficiency will be low, that in order to high efficiency, easy to operate, that only in the transfer paper and varnish Make an article in order to effectively solve.
