When produce cement bricks by concrete block making production line, it is necessary to use pallets to help support the green blocks. There are more pallets for options in the cement brick plants, like wooden block pallets, bamboo block pallets, pvc brick pallets, steel brick pallets and GMT block or brick pallets. Here we introduce a new kind of strong GMT pallets and explain why the GMT brick pallets can help you save money for the concrete block machines.
Why GMT Brick Pallets are Stronger than other Block Pallets?
GMT full name is Glass Mat Reinforced Thermoplastics. It is a kind of plastic brick pallets, which is made of fiber glass as reinforcing material and thermoplastic resin composite material, through heating and pressurizing. The glass fiber is three-dimensionally staggered like steel, and the resin is coated with glass fiber like cement-coated steel.
The GMT raw material is a new type of engineering plastic, which was developed in the past few years. It can be recycled, so it is considered one of the most promising new green materials in the 21th century. Now, the materials are widely applied in automobile industry (such as bumper, motor base), construction industry (like formwork) and concrete block machine pallets etc. Our Hongfa GMT brick pallet made from this material can be as solid as reinforced concrete, because the fiber in the pallet is structured like reinforced concrete. In hence, the rigidity and toughness of the GMT pallet used for concrete block machines are particularly strong.
What Are the Features and Advantages of GMT Brick Pallets for Block Plant?
This glass fiber pallets for block is the most economical pallets currently now for block making machine. As we all know that PVC brick pallets for concrete block making machine is heavy. The density of PVC block pallet is 1750-1800kg/m3, while the weight of the fiberglass brick pallet is about 1200kg/m3. Therefore, if using PVC brick pallets, it will increase the transport cost. Our Hongfa GMT brick pallets are lighter and help save transport cost.
For an example, 12 kg for an 18mm thickness GMT brick pallets, but it is 18 kg for PVC block palelts with the same specification, so GMT pallets for block making machine is 1/3 lighter than PVC pallets.
| Type of Pallets | GMT Pallet | PVC Pallet | Common Plastic Pallet | Bamboo Plywood Pallet |
| Weight | 21.5KG | 33KG | 23KG | 16.2KG |
Besides the light weight advantages, the GMT brick pallets have the following advantages:
– Endurable
The GMT brick pallets can be used for 8-10 years, better than PVC brick pallet and bamboo brick pallet)
– Impact Resistance
GMT brick pallet impact strength is equal to 30KJ/m2, while PVC block plate impact strength is less than or equal to 15KJ/m2, when comparing the impact strength under the same conditions. Drop hammer experiment test in the same height shows that: when GMT block pallet is slightly cracked, the PVC plate has been breakdown by drop hammer.
( Below is the laboratory drop tester: )
– Good Rigidity
Rigidity means the property of anti-bending. GMT block pallet is similar to PVC brick pallet about this aspect; but it is stronger the common plastic brick pallet (rubbish pallet) and bamboo plywood pallet. GMT plate elastic modulus 2.0-4.0GPa, and the PVC sheets elastic modulus 2.0-2.9GPa. The following diagram: GMT plate beeding effect compared with the PVC plate under the same stress conditions.
– Waterproof
The GMT block pallet water absorption rate is less than 1%. It performs better than the bamboo plywood after water soaking.
– Corrosion Resistance
The GMT brick pallets are resistant to the most acid-base salt, so it is without damage under strong acid.
– Anti-high And Low Temperature
When it is less than 20 degrees, the GMT brick pallets will not deform or crack. GMT pallets for concrete block machine are able to withstand high temperature of 60-90℃. It will not easily deform, and suitable for steam curing, but PVC plate is easy to deform at high temperature of 70 degree.
| Type of Pallets | GMT Pallet | PVC Pallet | Common Plastic Pallet | Bamboo Plywood Pallet |
| Low Temperature Resistance | -40°C | -10°C | -10°C | -40°C |
| High Temperature Resistance | Distortion Temperature 90°C, anti-aging | Distortion Temperature 70°C, easily aging | Distortion Temperature 70°C, easily aging | easily aging when above 50°C |
How Much Can You Save Money by Using GMT Brick Pallets for Concrete Block Machine?
Annual breakage rate: Bamboo plywood for block making machine is about 50%, PVC plate is about 15%, and GMT brick pallet is less than 1%. Take a standard Hongfa medium cement brick making machine HFB543S for an example, the block production line will need 2000pcs pallets.
The annual cost=the number of pallet*unit price*the annual breakage rate.
Bamboo plywood annual cost=2000*40*0.5=40,000RMB.
PVC plate annual cost=2000*60*0.15=18,000RMB.
GMT pallet annual cost=2000*78*0.01=1,560RMB.
The GMT block pallets are useful for concrete blocks, and now become more and more popular. Our Hongfa brick GMT pallets have been widely approved by all the concrete block manufacturers.
