Foreword: There are often some homeowners who will find that the floor they laid in the summer has cracked a very obvious gap. It is not known what causes this. In this regard, the relevant flooring industry explained that: summer room temperature is high, when the pavement floor into the fall and winter season, the physical factors affected by thermal expansion and contraction, easily deformed, and even more obvious cracks.

Floors paved in the winter, when it is summer, there will be swelling drums. Therefore, under normal circumstances, it is best to choose the pavement in the spring and autumn seasons. If you must choose to work in summer, you must avoid the sun exposure of the floor, to ensure that the room temperature is less than 30 °C; the construction temperature in winter should not be lower than 16 °C. As a city in the south, Chengdu has better flooring conditions than the northern cities. It mainly adopts methods such as ventilation and dehumidification.
The concrete method of paving is: Adjust the floor direction, from the door to the room, the maximum span of the floor is 6 meters by 8 meters. If you exceed this limit, you must leave a contraction joint and use the buckle; the wall root, the door bead interface Reserve expansion joints to be greater than 8 mm; splicing requirements of continuous, uniform, residual glue to be cleaned in time; baseboard must reach 12 mm thick, otherwise it is difficult to cover up the contraction joint; aluminum alloy layer thickness should be guaranteed in more than 2 mm, Too thin and easy to warp and deform. In addition, after the check-in, the floor is best maintained once a month, not only to extend the floor life, but also to prevent the moisture in the air from infiltrating the substrate, resulting in deformation of the floor.

CPVC Resin made by polyvinyl chloride( PVC) resin chlorinated modified system. Appearance is white or light yellow, tasteless, non-toxic loose grain or powder.
Characters:
I. Widely used range---Vicat Softening Point than PVC increases by 40℃, one of polymer can be used in high temperature and high pressure for long time;
II. Mechanics performance---tensile strength than PVC increases by 50%, 1 time increases than ABS resin, PP resin, CPVC could still maintain in a strong rigidity, fully meet at this temperature to the requirements of the equipment and pipeline especially close to 100℃;
III. Chemical corrosion resistance---CPVC not only has chemical corrosion resistance in room temperature, but also has good acid and alkali resistance at higher temperature, far better than PVC and other resin, it can replace the traditional material to handle corrosive substance;
IV. Good fire-resistance---CPVC with good self-extinguishing feature, the limiting oxygen index is 60, no form drop, limit flame spread and smoke generation;
V. Low co-efficient of heat conductivity---the heat conductivity of CPVC is 0.105KW/(mk), the CPVC heat-resisting pipes are with less heat loss and the heat insulating layer is unnecessary;
VI. The CPVC will not be affected by the chlorine left in water--Polyolefin Material( such as PP/PE) will decompose when they meet the chlorine left in the water, will not have crack or drip;
VII. The bacteria will not easy to breed---because the CPVC pipe will not be affected by the chlorine left in water, and also can resist the common sterilization chemicals;
VIII. It's same with PVC when processing---the processing way of CPVC finished products is same with PVC product, it's very easy and convenient.
