Two component hard foam high-pressure airless sprayer: Preparation before startup: a. Check if there are 2/3 cups of lubricating oil and DOP (di (2-ethylhexyl) phthalate) in the oil cups of each pump body. Check if there is sufficient lubricating oil in the oil mist device. Check if the water in the air-water separator has been drained. Check if all connectors are securely connected. Are all switches on the control panel in the OFF position. Is the factory air source switch in the closed state. Adjust the seal: The seals on the material and B material pumps should be tightened with adjustable locking nuts and periodically tightened. When frequent replacement of lubricating oil is required, the pump seal should be tightened. Check the feed filter and maintain it as needed.

When high-strength road repair materials are applied to road surface repair, a lot of things need to be mixed in order to achieve strength. Although high-strength road repair materials have high strength, they are relatively brittle overall. In this case, it is recommended to add steel fiber high-strength road repair materials during the mixing process, which can produce buffering under huge pressure.  

Secondly, it is necessary to choose high-strength road repair materials that solidify quickly and reach strength within 2 hours, because during road repair, it is necessary to open to traffic in a short period of time.

Then, when selecting steel fibers, it is important to pay attention to the proportion of addition, which depends on different situations, such as high-strength road repair materials and steel

Please refer to the guidance of technical personnel from the grouting material manufacturer for the proportion of fibers.

What's even more frightening is that it is also used by some people as an anchor for pendants during the installation of stone curtain walls. Of course, the reason why it attracts people to use it is not only because it is convenient to use, but also because it is cheap. The application of resin in stone repair and reinforcement has many problems due to the drawbacks of unsaturated resin as a stone repair material, which has prompted people to seek other materials to make stone repair and fruit enhancement more effective. With the continuous improvement of resin production technology and quality, and the constant innovation of curing materials, it has become an indispensable and relatively scientific material for repairing and strengthening stone. Resin refers to organic polymer compounds containing two or more functional groups in their molecules, usually processed into liquid resin for use.

Steel fibers need to be added during the mixing process to ensure even mixing.

Cleaning the road surface:

1. The road surface needs to be cleaned thoroughly and there should be no debris

2. Need to carve out a certain height for grouting

3. Need maintenance, watering and moisturizing the road surface

4. After the road repair, it will be open to traffic in about 2 hours.

Introduction to the causes of stone freezing damage: Due to inherent defects such as gaps and voids in the stone itself, water enters and freezes during cold seasons, causing damage to the stone. Freezing damage is one of the main causes of stone cracks, displacement of decorative panels, and decreased decorative effects. The main causes of water ingress into stone include rainwater, snow water, fog water, groundwater, and artificial water. These waters come into contact with the stone through natural and artificial means, entering the interior of the stone through its micropores. As the weather changes, the water inside the micropores repeatedly freezes, melts, and freezes, causing the stone to expand, contract, and expand again locally. The resulting repeated self stress ultimately causes the stone to expand and crack.

It is precisely because of this reason that the quartz stone market in China is chaotic, with a huge price gap between high and low quartz stones. Some small quartz stone manufacturers are still in a state of imitation and low price occupation of the market, disrupting the original order of the quartz stone market and widening the gap in quartz stone quality. The reason for the quality gap of quartz stone is the control of production raw materials. Quartz stone is mainly synthesized from quartz sand and unsaturated resin.
