In recent years, the rise of cold-chain logistics is the gradual growth of the refrigerated car market. Difficulties in market demand will cause some unscrupulous enterprises to oppose the speculation. It is a repertoire for the refrigerated truck market, which will undoubtedly increase the difficulty of purchase. Let's introduce to you today how to choose a cost-effective refrigerated truck .
The performance of refrigerated trucks is mainly reflected in the chassis, the insulation compartment, and the refrigerator. A good refrigerated truck must have the best performance in these three core areas.
First of all, the choice of chassis should be decided according to the amount of transported goods and the transport distance. The short-distance transport chooses the chassis of light trucks, and the heavy-duty medium-to-long-distance transport for heavy-duty trucks is to choose the chassis of heavy-duty trucks or traction semi-trailers. Some users tend to choose the import chassis when choosing, and the imported chassis is often better than the domestic chassis in performance, but its price is also much more expensive. In fact, in recent years, the performance of domestic chassis has been constantly optimized, and the quality is constantly improving. Therefore, the owner can make rational choices based on his own economic ability.
Secondly, the car body can be customized according to the needs of the user. For example, a refrigerated car that can be opened more often is designed to facilitate frequent loading and unloading of goods. Configuring some small components in the refrigerated box can meet the needs of special cargo transportation, making transportation more convenient and quick. This is also a humanized aspect in the design and production of refrigerated trucks.
Finally, the refrigerant can be said to be the soul of a refrigerated truck. Refrigerants are divided into non-independent units and independent refrigeration units. The non-independent refrigeration units are inexpensive and easy to repair, so they can be applied to short-distance distribution; independent refrigeration units can continue to work in the event of a car engine failure, to meet the safety of goods, and are therefore used for long distances. transport.
In the use of refrigerated trucks according to different transport conditions, there should be strict requirements, users should fully consider their own needs when buying refrigerated trucks , do not only consider the price factor, cool and rational choice of an environmentally friendly, comfortable, cost-effective refrigerated truck .
Chlorinated polyethylene is a saturated polymer material with a white powder appearance. It is non-toxic and tasteless. It has excellent weather resistance, ozone resistance, chemical resistance and aging resistance. It has good oil resistance, flame retardancy and coloring properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive performance. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, flame retardant transport belt , Waterproof coiled material, film and various profiles and other products.
As a PVC impact modifier, CPE135A has many advantages such as low price, excellent performance, and excellent aging resistance, but it has certain disadvantages in the use of high impact and high hardness products and low temperature resistant products CPE135A. For example, in the formulation of rigid PVC, a large amount of CPE will reduce the hardness and rigidity, which reduces the physical properties of the product; in addition, when the low temperature resistance requirement of PVC products exceeds minus 30°C, CPE135A cannot meet the requirements. Under normal circumstances, modified CPE, such as ACM, RGC135A, etc., can be selected for rigidity and hardness improvement; for low-temperature resistance modification, impact-resistant ACR or other impact modifiers with lower glass transition temperature can be selected.
