According to homebred spray the craft level of aluminium board is mixed the current situation, exist to be not worth below on quality:

Off color respect

Not same approve coating, color has difference badly; Be not one-time coherent exercise, install to besmear group by group, temperature of the spray time, lacquer that bake, humidity also has difference, can have off color; And coating ply error is big, off color also can appear after using particular fixed number of year.

Machine a respect

Homebred aluminium board often for pursuit beautiful and the treatment function hem that disregards aluminium board itself, hem place can produce tiny chelonian flaw; Appear easily after the course uses period of time the problem of a few safe respects.

Leveling respect

The flat platform after homebred plank leveling is losing wave height to amount to 4mm; Spray of high temperature of the classics after figuration also can arise be out of shape. Reason spray board the surface can arise exceeding rough whole.

The main distinction of both depends on the phase of lacquer and craft differring.

Rolling besmear beforehand is still coil in base material when shape, the program waits through pickling, leveling on automation line, according to the lacquer layer ply of the requirement, have computer control, through a few bake a few carbonado, finish inside relatively airtight space. After rolling besmear, be hank coils the aluminium of the layer that take a surname board. Like the basis when using dimension cuts out directly and fold a turn, can construction.

Spray is the norms that in the basis construction blueprint decides, to taking the aluminium of lacquer layer board after cut out and folding a turn to shape, the lacquer on reoccupy spray gun.

For wall of aluminous to the metal on the market act, breed is very much. With respect to lacquer level, main component spray, roll Tu Ji to eletroplate beforehand etc. Integral performance is compared, it is spray far under roll besmear beforehand, roll besmear to be on partial index beforehand under eletroplate; On the space, homebred and main it is spray, abroad already was to roll besmear product to take the main aspect beforehand, eletroplate the product is in abroad early also somebody was used. Why can home and abroad cause this to plant " acting " differ? Main reason has the following 2 respects:

Capital, technology and equipment.

Business of domestic act wall is much, scope is little, good and evil people mixed up, type of mill thering is no lack of is produced. To billions of dollar product line rolling besmear and strict technical form a complete set ask for, still do not have a requirement apparently.

Building concept and market-in concept element. Namely person disaster. The building is a project of vital and lasting importance just say on the mouth just, everybody is absorbed in at the moment interest and do not say long-term benefit. (the first floor that an example is mouth of Shanghai land home dish, the wall outside the price of ten square uses aluminium only model board stuck leave it at that, reduce cost, the result clinchs a deal Liao Liao) . Owner is dilettante, manufacturing business spells the price, jerry, depress salary, sacrificial quality, technical research and development and upgrade replacement is eyewash more, the result is whole industry stops a pace not before.
