When we choose a handy racket practice, then, in order to avoid the racket to change with good effect, the efficiency of the training, and increase spending on unnecessary, and maintenance of the racquet is good, and extend its reasonable use of sports for life, who wants to play ball is very important, and also reflects people from one side of the professional spirit.
A conform to the rules, can be used in the race, the bottom of the racket, sponge, rubber three parts. The introduction of the respective respectively for maintenance and matters needing attention in use.
     Today, the trend has and bottom in the 1960s, manifested in two different physical aspects. A light weight: the weight of the 1960s straight in 120-130 grams, HengBan in 150-160 grams, and now the backplane generally in 90-100 grams between, 2:60s thickness thin in the 6-7 mm, now is 5-6 mm. In order to pursue the two characteristics, and to keep the ball, don't eat, the seismic performance of strength, good at choosing materials, using qualitative relatively light timber. Such as: 60s of Sweden, and often used birch Sweden floor is today by Chinese parasol wood and wood, obtain greatly reduced the weight of the bat. However, due to the material is qualitative light, intensity of soft and weak, the floor is more easily damaged. Therefore, in use process, in addition to bottom in dry place will be broken, and prevent stress, and play in the process, must pay special attention to the bat and mesa and ground, such as the collision in feed many, but using alternate board, etc.it's athletes in practice, with the appropriate action by keeping a distance, more should avoid defeat for impatience, deliberately broke up with racket racket, tables and play and the baffle vices.
     The main factors that affect sponge properties are thickness, hardness, flexibility, pore size, number of aperture, and other factors. Because inflation, a sponge in use process, not excessive force, stress, low temperature, heat preservation, must pay attention to the proper temperature affects the elasticity of the sponge. The rubber and sponge with pamphlets, changing plate rubber, roasted with fire type electric iron head, with sponge rubber iron melt glue fully between the case for change damaged sponge rubber. Glue can make sponge foam, increase the elasticity, but with the floor to paste, the use of non-toxic glue, such as the special protection sponge, can also can protect floor.
     In table tennis tools, rubber, but in general variety can be divided into two kinds, one kind is the stick, one kind is positive. The stick include opinions and prevent arc, stick ZhengJiao including rubber, rubber and plastic. Due to the different quantity of cement with larger, rubber friction, opinions surface has strong adsorption, adhesion, rubber ball, not sliding contact point increase ball rotation. In order to fully exert the characteristics, in the use of opinions, it is important to keep the rubber clean. Don't use oil hand wipe rubber. After the play ball, every available to rinse water, rubber with plastic film, If there is water, remove dirt is also used as soap wash detergent, etc, reoccupy dry.
      Rubber contains quantity of cement paste is low, the tooth grain hardness, friction, rubber ball, the area is small, easy to slide. Based on the characteristics, such ZhengJiao use, paying special attention to keep dry rubber. If in the damp, can be used to reduce wipe desiccant rubber rubber surface humidity. The skin is posted rubber thin, generally with sponge paste, besmear again don't go too tried to glue, "roll" for rubber, senseless loss.
