1. It is necessary to allow the air-conditioning to be able to circulate between the loaded goods, and it is possible to maintain the temperature in the cold storage at an equilibrium temperature from beginning to end. It must be the location and manner of stacking mainly during loading. It must be noted that the piled goods cannot be stacked in and out of gas and cannot be stacked on the roof.
Refrigerated vehicle maintenance
2. If the refrigerated truck is loaded with green foods such as fruits and vegetables, it should be noted that fruits and vegetables will produce respiration heat. If the cold air circulation effect of the refrigerated truck is poor, the temperature in the middle part of the cabin will rise, which will directly affect the quality of the goods. If the distance between the goods is relatively close to the cold air exit, then the upper part of the goods will cause frostbite due to cold air. Therefore, protective measures need to be taken after the box is installed.
3, the health of cold storage cars need to do a good job of cleaning at all times, so as to ensure that the food being transported has a relatively good cleanliness. If it is fat, salt, etc., the substance adheres to the door, the interior, and the seal. Not only unsanitary performance, but also reduce vehicle corrosion.
4. When loading and unloading the loaded goods, after opening the cold storage door, the external air flow will enter the cold storage, which will cause the temperature in the storage tank to rise. Therefore, the speed should be increased after the goods are carried. In addition, if the cargo is being carried, it is necessary to hold the refrigeration unit up and running.
5. Prior to loading cargoes, the refrigerated trucks need to pay attention to the precooling transportation equipment and goods of the cold storage in order to guarantee the temperature of the loaded goods while transporting the goods. It is not possible to keep the goods cold or freeze them all in the cold room. If the temperature of the cold storage is relatively high or the temperature of the goods is relatively high, it is difficult to reduce the temperature to a suitable temperature. Therefore, before carrying out the loading, it is necessary to precool the cold storage as well as the cargo so that it can reach a more suitable transport temperature.
The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.
The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.
Judge good or bad
1. Look at the hue and surface roughness of the edge banding strip. The color of the surface of a good edge banding strip is also very important. Whether the color is close to the customized product and is gorgeous. If the surface is very rough and there are pull marks, the quality is definitely not much better. This is the surface quality of the edge banding strip. It has nothing to do with the quality of the inner material of the edge banding, mainly the production process of the edge banding factory and the production technical skills of the employees. A good edge banding strip is: the surface must be smooth, no blistering or seldom bubbling, no drawing or few drawing, moderate gloss, not too shiny or too matte (unless there are special requirements).
2. Check the flatness of the surface and bottom of the edge banding and whether the thickness is uniform, otherwise it will cause the joint between the edge band and the board, the glue line is too eye-catching or the gap between the board and the edge band is too large, which will affect the overall beauty. Details determine success or failure, and often a small detail problem may bring an embarrassing situation where the overall effect is not good.
3. Whether the edge trimming is whitish, whether the surface of the bent edge strip is severely whitish, and whether the ground color of the trimming strip is close to the surface color of the board in question. PVC Edge Banding strips are mainly made of PVC and Calcium Carbonate plus additives. If the calcium carbonate content is too high, whitening of the edge banding and bending will occur, which proves that the quality of such products is not good.
4. Whether the strength is okay and whether there is elasticity. High strength means good wear resistance, and the corresponding quality is better. Too high strength also means increased processing difficulty. Low elasticity means low wear resistance and low aging resistance. In addition, according to actual production needs, manual trimming is generally required, and soft spots can be made appropriately, and the automatic edge banding machine can make hard points appropriately.
5. Whether the adhesive is applied evenly and whether it is easy to fall off during use.
6. Smell whether the PVC edge banding strips taste or not. Products produced with good quality raw materials generally have a small taste. If the taste is too large, it means that the quality of the raw materials used in production is relatively poor.
