In people's impression, only mention plastic but think of pollution. Now the country has stipulated the production standard of plastic packaging. The professional bubble bags used for packaging are produced according to the quality standard stipulated by the country. With the improvement of people's awareness of environmental protection and the increasing demand for packaging, the development of bubble bags will be carried out in the direction of higher environmental protection and production efficiency. In the future, we will study packaging information itself and adjust the environmental protection of plastic products from the perspective of sustainable development.
At present, automation technology has accounted for more than 50% of the packaging production line. Domestic computer design and mechatronics control have been used to improve production efficiency, improve the flexibility and sensitivity of equipment, and increase the manipulator to end the messy packaging action. Each manipulator is controlled by a computer. The camera monitors the packaging action and feeds back the information to the computer to adjust the motion fluctuation and ensure the packaging quality. Since the 21st century, compared with the traditional packaging machinery and equipment, the new food packaging equipment has the characteristics of simplicity, high output, complete matching and higher automation of pearl cotton bags. In the future, bubble bag machinery will cooperate with the trend of industrial automation and promote the overall level of packaging equipment. New intelligent devices such as highly intelligent NC system, encoder and digital control components, power load control and so on have been widely used in packaging machinery equipment. Equipment users are more independent, sensitive, accurate, efficient and compatible in the operation process. Mainly used for the packaging of postal products. The bubble bag is an additional damping foam film. There are many small foam foam packages, so the body is light, elastic, sound proof, anti seismic and scratch resistant. It is widely used in electronics, appearance, ceramics, handicrafts, household appliances, distributors, kitchen, furniture, hardware tools, packaging films, glass products and precision instruments. Buffer, maintenance, etc. It can avoid kneading, touching and conflict of goods in the process of conveying, and has certain maintenance effect for goods afraid of extrusion or extrusion. In addition, special bubble bags such as anti-static can be produced by adding different additives to the material. Anti-static air cushion bag is used for packaging electronic components, such as integrated circuit board, card, etc.
热分析在一定的气氛下，密封胶带测量样品的质量随温度或时间的变化而变化，利用这种能力来讨论蒸发或降解等过程中伴随质量变化的情况。如果将TGA - MS或TGA - FTIR技术结合起来，还可以对气体的蒸发进行分析，从而得到更全面、准确的信息。颜辉测量更广泛地应用于聚合物数据的研发、功能测试和质量控制。例如，差示扫描量热计(DSC)可以用来研究热固性树脂固化反应的热效应，得到固化反应的起始温度、峰值温度和终点温度，还可以得到单位反应热和固化树脂玻璃化转变温度。这些数据对于确定树脂的加工条件、评价固化剂的配方具有重要的影响。DSC还可用于测定聚合物的玻璃化温度、结晶温度和熔点，为选择结晶聚合物的加工工艺、热处理条件等提供指导。
Thermal analysis in a certain atmosphere, sealant tape measurement sample quality changes with temperature or time changes, using this ability to discuss the evaporation or degradation process accompanied by quality changes. If the technology of TGA - MS or TGA - FTIR is combined, the evaporation of gas can also be analyzed, so that more comprehensive and accurate information can be obtained. Yan Hui measurement is more widely used in the research and development of polymer data, functional testing and quality control. For example, differential scanning calorimeter (DSC) can be used to study the thermal effect of curing reaction of thermosetting resin. The initial temperature, peak temperature and terminal temperature of curing reaction can be obtained. The unit reaction heat and glass transition temperature of curing resin can also be obtained. These data play an important role in determining the processing conditions of resins and evaluating the formulation of curing agents. DSC can also be used to determine the glass transition temperature, crystallization temperature and melting point of polymers, which can provide guidance for selecting the processing technology and heat treatment conditions of crystalline polymers.
