Production of modern pop false printed PVC stretch ceilings designs ideas concept market potential is huge
At home, the thermal shrinkage membrane is mainly used in the following three fields. In the area of beverage packaging, soft drinks packaging, dairy packaging, pure water packaging market needed heat
The total dosage of the shrink-membrane soft drink bottle was over 100,000 tons, and it was growing at an average annual rate of 18%. In the field of medicine packaging, the heat shrinkable film is replacing the carton, which greatly reduces the packaging cost of pharmaceutical enterprises. Pharmaceutical packaging mainly refers to the bottles, caps, boxes and films used in packaging drugs and medical machinery. In the area of beer packaging, beer production in China exceeded 518.9 million tons last year and about 82 billion beer bottles were needed, such as 5%
The heat shrinkable film bottle covers an annual consumption of 50 thousand tons, and the production market potential of modern pop false printed PVC stretch ceilings designs ideas is remarkable. modern pop false printed PVC stretch ceilings designs ideas manufacturer home think, although PVC heat shrinkable film is very huge potential market, but the choice of consumers for the product questions or the quality of the products and services. Hefei xiangfei plastic co., LTD., based on years of market experience, actively investigates consumers' preferences, and produces scientific, innovative, colorful and complete specifications. At present, our country
Plastic wrap heat shrinkable film is used in hundreds of thousands of tons of materials, including PVC, PS, PE and other materials, of which PVC is the most current heat shrinkable film. Modern pop false printing technology for the production of PVC stretch ceiling design concept to promote the development of the marketization of heat shrinkable film, PVC heat shrinkable film covered electronic products, medical products and so on the packaging of the industry, promote the development of the flexible packaging industry products. At the same time, the thermal contraction label, the shrinkage of the bottle cap has been developed. It can be seen that technology has become a powerful weapon to promote social progress.
1. The application of modern pop false printed PVC stretch ceilings designs ideas concept
modern pop false printed PVC stretch ceilings designs ideas concept is a two-component adhesive, activation temperature was 60 ℃ or so. Storage environment temperature should be at 5 ℃ to 30 ℃, 5 ℃ below flocculant can cause. The drums should not be placed directly on the ground and should be placed on wooden brackets, especially in winter. modern pop false printed PVC stretch ceilings designs ideas concept is valid for 6 months from the date of delivery.
modern pop false printed PVC stretch ceilings designs ideas configuration ratio main agent: curing agent = systematically, the main agent and curing agent are mixed, should keep the main agent in the condition of stirring, add curing agent and stir at least more than 3 minutes. The amount of glue produced each time shall be used up within 4 hours. The glue should be tightly covered with glue.
2. Requirements of spraying process
The spraying sequence is the end face, the front line, the front and the face, the plane part, the spraying can be; The plane of the plane of the end plane should be sprayed twice.
The active time between the main agent and the curing agent is 4-6 hours, the workpiece of the sprayed adhesive should be finished within 4 hours to obtain the best adhesive effect. Otherwise, due to the cross-linking reaction of the adhesive, the activation temperature should be raised, although the adhesion effect of the adhesive is good, but the temperature resistance is obviously reduced, and if the secondary spray will show the adhesive mark on the PVC surface.
After spraying, the surface is white and dry. The dry time is 30 to 50 minutes (depending on the temperature, humidity and glue quality of the environment).
The common fan is 1.5-2.0 meters from the workpiece, modern pop false printed PVC stretch ceilings designs ideas and the wet air is blown away to avoid the high humidity of the workpiece to produce the PVC bubbling.
In winter, in order to improve the temperature of the workpiece, can use small insulated building the workpiece heated to 20 to 25 ℃ under the condition of (banned temperature more than 35 ℃, modern pop false printed PVC stretch ceilings designs ideas otherwise will produce deformation). Spray adhesive should be not less than 16 ℃ environment in the water machine.
