Misunderstandings in the application of pavement joint tape in Hangzhou, Zhejiang Province

  Zhejiang Hangzhou Huatong pavement joint belt is like a band aid, which can quickly and timely deal with the problem of road cracks, but the effect of some customers after use can not meet the expectations, because there are improper operations when they use it
Next, let's talk about the misunderstandings in the use of Zhejiang Hangzhou pavement joint belt

1
The temperature Zui of Huatong sewing tape is good when it is used, and it is guaranteed to be above 5 ℃
When the temperature is low, the asphalt base on the joint surface of the joint sticking belt does not have good adhesion, and it is easy to fall off when sticking on the crack
Huatong seam tape can be used above 5 ℃
At 15 ℃, the seam tape has good effect Zui
When the temperature is low, the seam tape needs to be used after the lower film of the seam tape is removed and sprayed with a blowtorch
It can be used after increasing the temperature of the bonding surface

2
It is necessary to ensure that the joint of the road surface is clean and dry
If the pavement is not clean enough, there is dust or moisture, the joint sticking belt will not be in good contact with the road
In this way, the asphalt base of the joint sticking belt cannot be fully integrated with the road asphalt, which will affect the adhesion between both sides of the pavement crack and the joint sticking belt, resulting in the phenomenon of falling off of the joint sticking belt

3
After pasting, it needs to be fully compacted
There is a large gap between the joint sticking belt and the road surface after sticking
The joint sticking belt cannot be embedded into the crack
It needs to be compacted manually with rollers or hand hammers
When the viscosity of the joint sticking belt is strong, it can also be stepped on by feet, so that the joint sticking belt will not be taken away by vehicles when it is open to traffic

Huatong sewing tape, using high-quality raw materials and advanced technology, makes products that can stand the test, so it is worthy of your trust

The road is unblocked and Huatong is selected
