How to choose block machine pallet

The pallet is an auxiliary equipment for lifting brick in production process of various burn-free brick machines. The raw materials of the pallet are extensive, such as wood, plastic, bamboo. Each pallet has its own characteristics.

1. Steel burn-free brick machine pallet : Made of 8-10mm ordinary iron plate. It has the disadvantages of high cost, heavy weight, damaged brick machine equipment, etc.

2. High-pressure solid wood composite pallet. The raw material is solid wood, and the pallet is generally durable and relatively thin.


3. Solid wood pierced steel bracket pallet; High repair rate, low price, not easy to rot, the thickness of the plate is generally 30-40mm, the single weight is light, not wear-resistant, easy to break.

4. Multi-layer composite pallet; bamboo plywood, The bamboo glue board is characterized by light weight, normal impact resistance, low price and low investment. It is not abrasion resistant, not moisture resistant and easy to layer and rot. Surface fuzzing is serious.


5.PVC pallet: PVC pallets are made of PVC old plastic and stone powder as ingredients. It is characterized by low impact resistance, high price and high investment, and the weight of one piece is too heavy, easy to break.


GMT pallet

GMT is a composite material of glass fiber and thermoplastic resin. Like steel mixed with cement, glass fiber is three-dimensionally interlaced, and resin wrapped glass fiber. Therefore, the rigidity and toughness of the pallet are particularly strong. GMT is a new type of plastic used in automotive chassis, building templates, and is recyclable, is known as the most promising in the 21st century green materials.


             GMT pallets meet the following criteria

Test items Standards Test method
water absorption ≤0.5 soaking
bending strength ≥30MPa ASTM D638
flexural modulus ≥2.0MPa ASTM D638
length and width deviation ±3mm actual measurement
thickness ±1mm actual measurement
impact strength ≥12MJ/m2 ASTM D256
shore hardness ≥70d actual measurement
 

GMT bracket is not brittle at low temperature and deformation resistant at high temperature, because GMT is reinforced by long glass fiber. Look at the table below.

GMT pallets have good toughness and aging resistance. They have low breakage rate in long-term use, strong temperature resistance and good reputation.

GMT pallets are lighter in weight. Density is 2/3 of PVC board

GMT pallets are cheaper than PVC pallets and do not crack like bamboo plywood.
The strength of the GMT pallet is theoretically much stronger than that of the PVC pallet, especially the toughness (impact strength).

The surface hardness of GMT bracket is 72d, which is the same as that of PVC bracket, but more wear-resistant than bamboo plywood and plastics. Look at the table below.

In conclusion, GMT bracket has advantages over other brackets on the market. It has less damage in long-term use, high return rate, relatively cheap price, light weight, long-term use and not easy to damage. At present, it is the first choice for the bracket of unburned brick machine.
