When we hold a valuable printed matter, such as checks, certificates, banknotes, invoices, etc., once identified as counterfeit, the rights and interests of the holders are immediately damaged. Therefore, certain knowledge is required to identify the authenticity of tickets (coupons), so that timely measures can be taken to safeguard their rights and interests. 1. Paper recognition The paper is mainly composed of plant fibers and auxiliary materials, which are specially treated with Gab. Its main physical properties are: durability, tear resistance, resistance to stroke, smooth surface, easy to write, and sense of value. Therefore, it can be identified from the following aspects: 1. Is there any watermark or depth of watermark on the anti-counterfeit paper? Illumination of light or comparison of two identical tickets (coupons) can be used to identify serious and false. 2. The color and location of the dark lines. Ordinary papers do not need to have dark lines, only special price ticket (coupon) paper. Dark lines have many different colors, and they can be used in a single color or a mixture of multiple colors in production. If the position and color match, it is the authentic product Of course, sometimes the slight difference is not a fake, but an error at the time of production. 3. Special fiber structure. According to the characteristics of different tickets (coupons), different fiber filaments are used in the production and their distribution is also different. Sometimes it is colored visible fiber filaments, and there are also invisible fiber filaments. Both of them can be reflected by fluorescent light under ultraviolet light, and have different colors and special structures. These are the key points of identification. 4. The thickness and uniformity of the paper. The thickness and uniformity of the paper can be seen through light or light to see if it is evenly distributed, and can also be distinguished by hand. Second, the identification of ink The identification of ink is a more professional method, and most people cannot easily identify it. The ink is made by mixing and mixing pigments and some additives, so it can be distinguished from the following methods: 1. Color and color: carefully observe whether the color of the printed matter is correct and bright, and it has gloss. 2. Texture: Letterpress and gravure prints often have a strong texture and bright colors. You can directly touch the surface with a convex or concave feeling by hand. Plain printing shows that the print is more even and the print is lighter. 3. Water resistance: according to the different printed products. Water-resistant inks can be selected. If there is a value certificate (coupon) to prevent tampering with the water, alcohol and other liquids, water-soluble ink is used to make it difficult to achieve the purpose. 4. Lightfastness: After using strong ultraviolet rays and sunlight for a certain period of time, inferior inks often fade.
CLW GROUP TRUCK Refrigerated truck, Chill Truck, Freezer Truck,Refrigerator truck,refrigerated van,refrigerator wagon, refrigerator car is used to transport frozen or fresh goods enclosed Van trucks, is equipped with a refrigerating unit of refrigeration device and polyurethane insulating compartment dedicated refrigerated transport cars, commonly used in frozen food transport (refrigerated truck), dairy (milk truck), fruits and vegetables (perishable cargo transport vehicles), vaccine and drug (vaccine transportation vehicles).

CLW GROUP TRUCK Refrigerated truck brief introduction
CLW GROUP TRUCK Refrigerated truck Structure:
Refrigerator car by walking part of the special purpose vehicle chassis, and heat insulation box body (generally consists of polyurethane materials, glass steel, color steel plate, stainless steel, etc.), refrigeration units, inside temperature recorder, etc. components, for the special requirements of the vehicle, such as meat hook car, installed with a meat hook, waist, the guide rail of aluminum alloy, ventilation slots and other optional.
CLW GROUP TRUCK Refrigerated truck Production technology of refrigerated compartment:
1, divided into pieces of "sandwich" plate bonding type, the domestic large refrigerated truck manufacturers are using this technology, the use of this technology to produce a high thermal insulation performance of refrigerated cars.
Refrigerated truck
2, divided into assembly of injection foaming type.
3, the whole skeleton injection foam type.
4, vacuum adsorption paste
CLW GROUP TRUCK Refrigerated truck Classification of refrigerating units:
Refrigerating unit is divided into non independent refrigeration unit and independent refrigeration unit. Domestic and imported units, etc.. General models are used in the external cooler, a mini refrigerator car with built-in refrigerator. For the lower temperature requirements of refrigerated vehicles, can be taken to the car body cold plate (equivalent to the function of the evaporator).
classification
According to the chassis manufacturer classification: Dongfeng refrigerator car, Changan Star refrigerator car, Qingling refrigerated trucks, refrigerated truck Jiangling, Jianghuai refrigerated trucks, Beiqi Futian refrigerated trucks
Semi Trailer
According to the bearing capacity of the chassis classification: Micro refrigerated trucks, small refrigerated trucks, medium-sized refrigerated trucks, large refrigerated trucks
According to the classification of car type: Bread refrigerated truck, refrigerated trucks, Semi-Trailer van truck
Characteristic
The container of the sealed refrigerated truck needs to be strictly sealed to reduce the heat exchange with the outside, so as to ensure the lower temperature in the refrigerator.
Refrigerated truck
The refrigeration equipment is connected with the container and provides a steady stream of refrigeration to ensure that the temperature of the container is in the range of the goods permitted.
Portability is generally used in refrigerated trucks transport goods are not for a long time to save the items, although there are refrigeration equipment, still need to quickly reach the destination.
A container similar to a heat insulated refrigerated truck is made of a material with better heat insulation effect, and the heat exchange is reduced.
CLW GROUP TRUCK Refrigerated truck Key equipment
1 refrigeration vehicle refrigeration unit
Refrigerated trucks refrigeration unit: for refrigerated container trucks to provide a steady stream of "cold" is an important equipment, generally installed in the container to the top of the front, air conditioning like appearance, but than the same volume of air conditioning has stronger refrigerating capacity.
Refrigeration unit is generally divided into two, independent type units and non independent type units. The difference lies in the independent unit completely by another unit to generate electricity for the maintenance work, non independent unit is completely through the work of the vehicle engine power to drive unit of the refrigeration work.

Selection of refrigerating unit of refrigerated truck
According to the volume of refrigerated compartment and transport of goods to the requirements of the temperature, to choose a different power refrigeration unit.
2 refrigerated truck insulation body
The refrigeration unit of the refrigerated truck is used for temperature control, and the effect of the box body is used for maintaining the temperature. If the chiller is the provider of energy, the compartment is the storage of energy. In the three parts of the refrigerated truck, the refrigerating unit and the heat preservation box body are the most important, the removal of the chassis can be used as a small heat preservation, cold storage.
Selection of thermal insulation compartment
Body selection generally follow a few points: good thermal insulation performance, light weight, not easy to damage.
