Jinsi ya kutofautisha ubora wa coil ya alumini iliyotiwa rangi?

Coil ya alumini iliyotiwa rangi (roll ya alumini iliyotiwa rangi), kama jina linavyopendekeza, ni rangi ya mipako ya uso ya sahani alumini au (roll ya alumini). Ya kawaida ni alumini iliyopakwa rangi ya fluorocarbon (roll ya alumini iliyotiwa rangi), alumini ya rangi ya polyester iliyofunikwa (roll ya alumini iliyotiwa rangi), ambayo hutumiwa sana katika sahani ya plastiki ya alumini, veneer ya alumini, aluminum honeycomb plate, aluminum ceiling, roof surface, leftover materials, cans and electronic products. Its performance is very stable and not easy to corrode. After special treatment, the surface can achieve 30-year quality assurance. The weight per unit volume is the lightest among metal materials. Color coated aluminum is the most popular new material at present.

colour coated aluminum coil

Color coated aluminum coil has the following characteristics:

1. Utulivu: no composite high temperature indentation on the surface. The plate surface has no residual stress and no deformation after shearing.

2. Mapambo: painted with wood grain and stone grain, with realistic physical texture and fresh natural beauty. Patterns are made at will, kuwapa wateja anuwai ya chaguzi za kibinafsi, enriching the humanistic connotation of products and giving people more beautiful enjoyment.

3. Upinzani wa hali ya hewa: the paint pattern formed by coating and baking at high temperature has high gloss retention, good color stability and minimal color difference change. The warranty of polyester paint is 10 miaka, and that of fluorocarbon paint is more than 20 miaka.

4. Mechanical: high quality aluminum, plastiki na wambiso huchaguliwa, na teknolojia ya hali ya juu ya mchanganyiko inapitishwa. The product has the bending and bending strength required by the decorative board. Under the climate of four seasons, the changes of wind pressure, joto, unyevu na mambo mengine hayatasababisha kupiga, deformation and expansion.

5. Ulinzi wa mazingira: it is resistant to the corrosion of salt, alkali and acid rain, will not corrode itself, create poisonous bacteria, haitatoa gesi yoyote yenye sumu, will not cause the corrosion of keel and fasteners, and is flame retardant. It shall not be lower than grade B1 according to national regulations.
