Polypropylene
fiber by polypropylene and a variety of organic and inorganic materials,
refined by special composite technology, products can be formed in the concrete
three-dimensional supporting role to the distribution of the mesh, the micro
cracks formed at the beginning of the hardening concrete was blocked in the
process of development, to develop further. Thus, it can improve the fracture
toughness of concrete and improve the anti-seepage properties of concrete. It
is a new ideal material for mortar, concrete engineering, anti-cracking,
anti-seepage, wear-resisting and heat preservation.
The anti-cracking ability of the non-structural crack in the
plastic stage of concrete is improved.
It is a kind of effective rigid self-waterproofing material.
The range of noil is 0.6-1.8 kg/m3, and the concrete
anti-cracking anti-seepage is usually 0.9kg/m3.
Main functions: to prevent concrete cracks, improve the
permeability resistance of concrete, improve the freezing-thawing resisting
performance of concrete, improve the impact resistance of concrete, folding
resistance, fatigue resistance, seismic performance, improve the durability of
concrete, aging resistance, improve the fireproof performance of concrete.

The belt reflection method is very simple. First, introspect the tension of the belt. At this time, you can use the thumb to strongly press the belt between the two pulleys. The pressing force is about 10 kg. Assuming that the belt is about 10 mm in depression, it is considered that the belt tension is appropriate. Assuming that the amount of reduction is excessive, the tension of the belt is considered to be insufficient. Assuming that there is almost no reduction in the belt, the tension of the belt is considered excessive. In the absence of tension, the belt is slippery. When the tension is too large, it is very easy to damage the bearings of various auxiliary machines. For this purpose, the relevant adjusting nuts or bolts should be loosened and the tension of the belt should be adjusted to the optimum shape.
In addition, car maintenance must also pay attention to the wear of the belt. Old belts are worn out and the contact area between belts and pulleys is drastically reduced. At this time, just press the belt with force and the belt sinks deep into the groove of the pulley. The belt rubber also has an aging problem. Assuming that the belt rubber is seriously aged, the new belt must be changed in time.
The car engine is the brain of the car. If the engine is bad, it means that a car is useless. When a car is running on the road every day, if it takes a long time, it may cause the engine belt to wear out or deteriorate. Therefore, the owner usually starts to inspect the belt for a while to avoid unnecessary troubles.

Automotive Belt Maintenance - Regular Inspection Is Key
Vehicle maintenance is defined for the belt wear and ageing prevention of automotive engines. The rare root belts are defined at the front of the machine and each belt bears the primary result. On the proposal machine, various types of auxiliary machines are driven via belt drives, such as the shrinking machines for air conditioners, power steering pumps, and alternators. Assuming that the belt is broken, slippage may occur, which will cause the related auxiliary engine to lose its function or reduce its function, and then affect the normal operation of the car.
