Liu Gong introduced that many new houses that were inspected last year met with more than a dozen households suffering from air pollution. Some of them were sick children, some had problems with the health of the elderly, and the test results showed that the harmful gases were exceeding the standard. These consumers only came up with tests after their family members had health problems, but more people still had no sense of air testing. Today's consumers pay more attention to the purchase of green building materials. After the renovation, they do not smell too much and they think that there is no problem. For this simple sensory identification, Liu Gong believes that the nose can sometimes be deceived, tasteless is not necessarily uncontaminated, and individual harmful gases are colorless and odorless. People in the domestic decoration market are not yet completely “greenâ€. There is a sense of health after checking first, and if there is strength, the new house is best equipped with an air purifier to physically adsorb harmful gases. Yesterday, Liu Gong gave the readers an example. When a family in Nankai District was renovated, they all laid a large core board under the laminate flooring. Later, the whole family got iritis around the eyes. After testing, the formaldehyde in the room was seriously exceeded and was removed. Daxin board, eye conditions have also eased. This reporter learned of this group of data: The number of deaths caused by indoor air pollution in the world has reached 11.1 million every year, about 304 people per day; a hospital in Beijing carried out a survey of family living environment when he was admitted to leukemia children and found that 90% The little patient's home was renovated within six months. Experts speculate that the indoor environmental pollution caused by the decoration is a cause of a significant increase in childhood leukemia patients. Liu Gong finally suggested that consumers spend money on decoration before they hope to be healthy. After the renovation, the test is to protect their health.

Diamond cutting piece is a widely used in stone, concrete, precast board, new and old roads, ceramics and other hard brittle materials processing.
Diamond cutting pieces are mainly composed of two parts; Matrix and cutter head,
The matrix is the main support part of the bonding tool head, and the tool head is the cutting part in the process of use.
The tool head will be constantly consumed in use, while the matrix will not. The reason why the tool head can play a cutting role is that it contains diamond. Diamond, as the hardest material at present, cuts the processed object by friction in the tool head, while diamond particles are wrapped in metal inside the tool head.
According to the shape of the knife head, there are different effects:
1. Continuous edge Saw Blade: continuous saw diamond cutting blade, generally made by sintering method, water must be added when cutting to ensure the cutting effect, and the type of gap will be cut by laser.
2, knife head cutting piece: serrated disconnect, cutting speed, suitable for dry and wet cutting methods.
3, corrugated cutting piece: combined with the advantages of the first 1, 2, serrated continuous corrugated uniform convex and concave, improve the cutting speed, increase the service life.

Green house materials are purchased in every possible way before the renovation, but the inspection after the renovation has been ignored by most people. Recently, many of the readers received by Liu Dakui, Director of the Tianjin Office of the China Interior Design Association's Erlebuch Environmental Monitoring Center, were asking a question. Is the house properly renovated? Liu Gong explained to the reader that if the nose can directly feel the stimulating smell, it is best to check in and then check in. Even if there is no taste, it is better to conduct partial testing for the health of the whole family.
