The technical requirements:

The use of signs licensing round, Phi 60cm, using the import 3M seven grade reflective film, computer cutting,mechanical film, reflective effect, durability strong, in the natural environment can maintain not fade within seven years, do not fall off, cracking etc.. Aluminum alloy plate thickness not less than 1.2-1.5mm, the edge board surface smooth, smooth, clean, install the overall requirements of signs: fixed on the upright post withaluminum alloy or stainless steel rivets, column using spray antirust processing, rubber reflective invertedframe of F60mm × 2000mm, features: will not damage thecar tires, safe and durable, never rust. Indoor tag using 2 * 3 * 1.2 cm square through suspension. To set a regular,consistent style, the appropriate position, good vision,comply with GB5768 regulations. Pavement marking paintcan be divided into solvent at room temperature and hot melt type two categories.

Technical note:

1, normal temperature type paint, epoxy, acrylic esterrubber. Usually our use of, but the service life is 36months or so wear.

2, hot melt coating without solvent, construction need high temperature when the powder material is melted, the use of special equipment coating deposited on thepavement, condensed into marking. This marking fast solidification, strong wear resistance, service life of up to 20-36 months, reflecting good, suitable for busy cityroads and motorways. The road marking paint by the national Ministry of construction, Ministry of transportationrecommended cold Tu Lu topcoat and hot melt coatingfor choice, its abrasion resistance, water resistance are quality assurance. According to GB3186, hot melt coatingusing access card (Guangzhou city traffic policedesignated road marking special card).

The sign, heat reflective marking production procedures

A, sign making

Materials: the 1.2 mm to 1.5 mm thick high qualityaluminum alloy plate; reflective film state departments of Transportation approved the use of and the United States of America 3M company production, weathering period is more than seven years.

1), according to the sign face size requirements, foraluminum alloy plate and a reflecting film cut.

2), cleaning of aluminum alloy plate

(1): with 100 clean cloth on the aluminum plate grinding,the aluminum surface roughness.

(2): the oil with detergent to wash the surface of the aluminum plate.

(3): and finally washed with water and air dry plate.

3), with roller press will be affixed reflective film onaluminum have been cleaned for use.

4), computer typesetting pattern and text, use thecomputer engraving machine directly in the reflective filmcarve patterns or characters.

5), screen printing pattern: 3M special ink evenly coated on the screen, with a squeegee to ink evenly scraping on reflecting film; then the reflective film printed on the dryingrack, into the oven baking.
