Product Detail

Product Tags

The external wall hanging board for steel structure building material is a composite material, mainly composed of three parts, the surface is a veneer metal plate, the middle layer is a polyurethane foam insulation layer, and the bottom surface is an aluminum foil protective layer. The cost is relatively high, and the requirements for the composite adhesive material polyurethane glue sealant are also relatively high. There are high-strength, high-weather-resistant polyurethane sealants that can meet the high requirements of fireproof materials for steel structure building maintenance.The color steel plate movable house has the advantages of light weight, high strength, heat preservation and heat insulation, beautiful and durable, etc. It is a high-level building that integrates construction and decoration, and is quick to install. The color steel plate movable house is clean in construction and is widely used in large-span factories, warehouses, office buildings, villas, roof additions, air purification rooms, cold storage, shops, kiosks and temporary houses. The light color steel plate sandwich panel whose square meter weight is less than 14KG can fully reduce the structural load and reduce the structural cost of the mobile house.

Color steel plate coating is a product made of cold-rolled steel plate and galvanized steel plate, after surface chemical treatment, coating (roll coating) or composite organic film (PVC film, etc.), and then baking and curing. Some people call this product "pre-rolled color steel plate" and "plastic color steel plate". Color plate products are produced by manufacturers in rolls on a continuous production line, so they are also called color-coated steel coils. Color steel plate not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials. Color steel plate is an emerging material respected in the world today. With the advancement of science and technology, the enhancement of environmental awareness, and the improvement of people’s living standards, color-steel mobile homes have increasingly shown their strong vitality and broad market prospects. They are popular in construction, home appliances, electromechanical, transportation, interior decoration, and office appliances. And the favor of other industries.

Product Features

1

Excellent fast curing
performance

≥60°C hot pressing for 5-7 minutes to cure quickly. This product can reduce labor, avoid the frequent mismatching of personnel operation, and the phenomenon of open glue and bulge caused by uneven glue amount, and ensure the stable quality of customers' plates.

2

High process fault
tolerance

Intermittent production can be used in the spray coating process (the spray coating process can be paused for 1-2 minutes, and the spray gun does not block the gun head).

3

Suitable for curtain
coating and spraying

It is suitable for semi-automatic and fully automatic line production and manufacturing, improves production efficiency, and has excellent shower and spraying effects.

4

DP hot pressing
technology

An innovative technology that embeds DP in the main agent of polyurethane glue. That is, the DP is embedded in the main agent. After high temperature, the DP in the main agent is caused to diffuse rapidly, and the curing and crosslinking speed of the main agent and the polymerized MDI is promoted, and the bonding can be cured in 5 minutes.

Operation Specification

STEP 01 The surface of substrate should be flat and clean.

Flatness standard: +0.1mm surface must be clean, oil-free, dry and water-free.

STEP 02 The ratio of adhesive is critical.

The supporting roles of the main agent (off-white) and curing agent (dark brown) are executed in corresponding proportions, such as 100:25, 100:20

STEP 03 Stir the glue evenly

After mixing the main agent and the curing agent, stir evenly quickly, and use a stirrer to repeatedly pick up the gel 3-5 times without silky brown liquid. The mixed glue will be used up within 20 minutes in summer and 35 minutes in winter

STEP 04 Standard of the amount

(1) 200-350 grams (materials with smooth interlayer: such as inorganic boards, foam boards, etc.)

(2) 300-500 grams for delivery (materials with interlayer porous: such as rock wool, honeycomb and other materials)

STEP 05 Sufficient pressurization time

The glued board should be compounded within 5-8 minutes and pressurized within 40-60 minutes. The pressurization time is 4-6 hours in summer and 6-10 hours in winter. Before the pressure is relieved, the adhesive should be basically cured

STEP 06 Sufficient compression strength

Pressure requirement: 80-150kg/m², the pressure must be balanced.

STEP 07 Set aside for a while after decompression

The curing temperature is above 20℃, and it can be processed lightly after 24 hours, and can be processed deeply after 72 hours.

STEP 08 Gluing equipment should be washed frequently

After the glue is used up every day, please clean it with dichloromethane, acetone, thinner and other solvents to avoid clogging of the glued teeth and affect the amount of glue and the uniformity of the glue.
