Blockboard is a multi-ply board with a block core. This gives the board optimum flatness of each panel as well as a high resistance to wrapping. Blockboard is obtainable in both lightweight and heavyweight, where by the heavyweight board is normally classed as laminboard.
Luli Group Co., Ltd, is a leading supplier if wood panel products since year 1985, has the capability and capacity to produce high quality blockboard yet with competitive pricing. And we are able to assist you at all time with professional handling.
Advantages of Blockboard:
High dimensional stability
Termite and borer resistant
Stable in all weather conditions

Take the example of the longevity digitization process of the car gearbox bearing as an example: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
(1) The problem is widely used in ball bearings in passenger car gearboxes; the original service life is shorter than the extra life calculated according to the standard method juice; the performance is early fatigue and high noise. Bearings in other parts of the car The lifespan is higher than the extra life.
(2) Failure analysis The quality of the inspected gearbox is outstanding; the bearing device cooperates normally; it is smooth and plentiful; the suspected smooth oil does not enter the upper part of the bearing. However, all the inner ring channels have indentations or craters. Or there is a surface cracking type of fatigue and shedding; instead of secondary surface shedding type damage; when the oil is abundant, it does not cause such an appearance.
It was found that the outer surface of the channel was mixed with metal particles such as iron, copper, aluminum and zinc, and non-metal scraps such as rubber, sand and plastic.
Discrimination: These foreign objects and the indentations formed by them damage the integrity of the oil film; it is verified by the test that causes the early failure of the bearing; the above discrimination is correct.
(3) The solution has adopted the increase of steel ball type, special heat treatment type or even double row ball type and vacuum remelting steel bearing; the value is more and more valuable; and the life progress is not large.
Finally, it was developed into a "sealed hygienic" type bearing; it has achieved great success. This kind of bearing is a special rubber sealing ring on each side of the original specification bearing; the characteristic is that the sealing ring is mainly used to avoid dirt. Intrusion into the bearing; not the same as the bearing seal that is primarily intended to adhere to grease.
(4) The role and the development of the rough seal sanitary bearing in the live simulation test shows that the test life is more than 7 times higher than the original bearing of the same scale standard; even the bearing with smaller scale standard; The number has also improved by more than 4 times.
This kind of bearing is cheaper; it promises to use high quality smooth grease; working noise. The ash is extended to 25 standards; this type of bearing is used in various gearboxes of 25 cars and trucks to replace the original The use of a variety of more expensive and the use of short life, often difficult problems of the bearing.
Sealed sanitary short cylindrical roller bearings and tapered roller bearings; have been effectively used in various rolling equipment; this type of bearing continues to be carried out in other fields of application.
