When you need to buy a second-hand LED advertising car, you have to communicate with the corresponding sales staff for your actual needs. After all, the salesperson is professional and can make appropriate recommendations based on your requirements. After further identifying the second-hand LED advertising vehicle model, it can meet the needs of its advertising use, then you can take the following process to purchase. However, everybody needs to pay attention when inspecting vehicles. This is a link that must be observed. Be careful to avoid losses.

LED广告车

Because it is a second-hand LED advertising vehicle, so the quality of the car and the new car is very different, but in the inspection, the most important thing is to observe the use of LED display results. LED display is only the most important part of the LED advertising car, but also directly related to the use of publicity, in the examination, you can open the display to see how the effectiveness of its advertising films, LED screens are There have been mosaics, dead spots or sudden blue screens and black screens.

In addition, also need to pay attention to the second-hand LED advertising vehicle paint and how the outside of the situation, although it is used cars do not say, but the exterior appearance of the car can not be crushed, driving a LED advertising car who will be happy Follow the attention. In addition, it is also necessary to inspect the production process of the vehicle, so that the future use effect and the service life of the vehicle can be estimated in mind.


Then observe the second-hand LED advertising vehicle mileage, after all, is second-hand, so it is normal to have mileage, but still cautious to watch to ensure that the vehicle mileage should not be too large, and there is also view To some related supporting documents for used LED advertising vehicles, look at the date of manufacture on the vehicle and the date of shipment. If the driver or related person of the LED advertising vehicle has never been operated, not only the relevant vehicle certificates and vehicle conditions need to be inspected, but the operation of the LED advertising vehicle is still open to learning, and the comparatively wrong operation is Will bring very inconvenient influence.


Finally, in a few words, as the saying goes, one penny and one goods, although it is to buy second-hand LED advertising vehicles, but the price needs to be related to the quality of the vehicle itself, not because hundreds of thousands In terms of price differences, we have chosen low-priced second-hand advertisement vehicles that are suitable for their own needs and the quality of vehicle performance and quality is the ultimate choice.


Heat Exchanger Category

Application Field
Thin film scraper evaporator is widely used in heat interchange project. Particularly in Thermosensitive materials heat interchange, scraper are beneficial in heat interchange process, Through different design of scrapers, the distillation of complex products can be carried out. Quality result have been obtained for dissolution, stripping, reaction, degassing, deodorizing(gas) and so on.
Medicine: antibiotics, sugar solution,Methylimidazole,Mononitrile amineetc;
Food Product: Juice, Pigments, flavors, spices, enzymes, lactic acid, xylose, starch sugar, potassium sorbate;
Grease: Lecithin, VE, liver oil, oleic acid, glycerin, fatty acid, waste lubricating oil, alkylpolyglycoside, alcohol ether sulfate;
synthetic resin: Polyamide resin, epoxy resin, paraformaldehyde,PPS,PBT, propylene formate
Synthetic fiber: PTA, DMT, Carbon fiber, polytetrahydrofuran, polyether polyol, etc;
Petrochemistry: TDI, MDI, Trimethylhydroquinone, trimethylolpropane, sodium hydroxide, etc;
Pesticide biology: Herbicides such as acetochlor, propionamine, chlorpyrifos, furanol, insecticide, herbicide, acaricide;
Waste: Inorganic salt wastewateretc


Features
The equipment adopts centrifugal rotor of sliding groove, which is the latest structure evaporator abroad, The film can be formed even at low flow rate, The sediment in treatment solution attached to inner wall can be quickly removed by the movable scraper, evaporation can be increase to 40-69% compare to fixed gap scraper evaporator, listed below are features and functions:
1.High heat transfer coefficient value, high evaporative capacity, Evaporation intensity can reach up to 200kg/㎡high thermal efficiency
2.Short heating time, work under vacuum condition is much more beneficial to thermosensitive materials, keep various components without any decomposition to ensure quality.
3.It can adapt wide range of viscosity changes. High and low viscosity materials can be treated, and viscosity of materials can be as high as 100000 centipoise.
4.rotate the scraper groove can adjust material handling time in evaporator
5.Grinded and polished inner tube can avoid scaling
6.Easy to operate, production runs automatically under sealed condition.
7.Simple structure uses less area occupancy,convenient maintenance
