Resin, as an ancient material, has been used by people. Amber wax used to make crafts, can be used as medicine or rosin, frankincense as a chemical raw material, to make tonic peach gum shellac. These solid and semi-solids, which are formed by the condensation of viscous liquids secreted by plants or tree animals, have different uses, but all have the same characteristics. They are softened and melted by heat, and are hardly soluble in water, but soluble in other organic solvents.
However, natural resins are rare and expensive. At the beginning of the last century, with the development of electrical appliances, synthetic resins were invented in search of alternatives to natural resins in insulating varnishes. Synthetic resins are now widely used in plastics, coatings, synthetic fibers, various packaging materials, electrical, electrical and automotive materials. It can be said that synthetic resin is ubiquitous in our lives and is the most synthetic material with the highest yield and consumption.
In recent years, research and development and application of synthetic resins have shifted from how to increase production capacity to how to produce and use more environmentally friendly and higher performance products. Denso, as one of the world's leading auto parts manufacturers, has also been challenging this issue. In order to reduce the environmental load, Denso is developing a series of new resin materials that use plant molecular structures. The polycarbonate resin (PC) obtained from starch and the polyurethane resin obtained from castor oil are used in electronic products.
Electric equipment made of plant material resin
The bio-PC prepared from starch has the advantages of surface hardness and optical properties compared with the polycarbonate resin of the petrochemical extract, and the water decomposability is also stronger. At the same time, the light deflection is small, and its own color development is high, and it can be used for production without painting. As a high-design, high-hardness resin sheet, it has been used as a navigation instrument panel for Toyota Motor Corporation.
Castor oil is a vegetable oil extracted from castor seeds used as a raw material for coatings and waxed products. This electric equipment has developed a polyurethane resin excellent in heat resistance from the molecular structure of castor oil, and is used as a protective material for the connection portion of a vehicle exhaust gas sensing system.
The vehicle exhaust gas sensing system is a sensing system for detecting the emission concentration of a vehicle exhaust, and it is required to find a material with high heat resistance. Therefore, the previously used sensor control unit is a highly expensive silicone resin coating. Polyurethane resin developed by Denso is cheaper than silicone resin, and it is also the world's first to achieve 150° heat resistance, and has achieved a significant reduction in exhaust emissions. Resins prepared from plants rather than fossil fuels are non-depleted resources, and they do not cause an increase in the total amount of CO2 in the atmosphere during heat recovery. With the maturity of the electric plant resin technology, the polyurethane resin prepared by castor oil has been developed and commercialized, and a wider application platform has been installed.
In 2016, Denso planned “Environmental Vision 2025†as a guide to action to achieve a sustainable society by 2050. In the future, Denso will continue to develop plant resins and expand product applications, with a view to reducing the predatory use of limited petroleum resources, while reducing the CO2 emissions by establishing the product's own life cycle, contributing to the fight against global warming. .
Introduction to Denso:
Denso is one of the world's leading auto parts manufacturers, ranking 268th among the world's top 500 companies in 2016. Today, Denso has nearly 200 affiliated companies in more than 30 countries and regions around the world, with more than 150,000 employees. As a general company of Denso in China, Denso (China) Investment Co., Ltd. was established in 2003. At present, it has established 30 related companies including production companies, sales companies and software development companies in China. Sales, after-sales service system and production supply system.
In 2017, Denso presented a new brand slogan: “Crafting the Coreâ€. The new slogan conveys that “Telecommunications will play a greater role in creating the soul of the enterprise, creating new values ​​and creating various core things for the world†Willingness. Building a harmonious future where people, vehicles and the environment coexist harmoniously is the vision of Denso. In the future, Denso will continue to work on environmental protection, peace of mind, safety technology and product development, and actively contribute to the Chinese society.
Fruit Vegetable Blanching Machine
Fruit Vegetable Blanching Machine:
This machine is made of full 304 stainless steel. It is avaliable for different kinds of fruits vegetables, bottles etc.
This vegetable blanching machine is used to protect color and make good taste for chips. With the hot water to cook the chips for the good taste. It is mainly equipped with our factory production of vegetables processing line, Fried potato chips (French fries) assembly line, drying dehydration lines.
Equipment advantages:
1. The blanching machine is mainly used for the processing of vegetables and petal plants. The purpose of the blanching machine is to preserve the color. The water inside the blanching machine is hot water, and the heating method is electric heating or steam heating. The blanching machine adopts mechanized operation completely in the process of use, without manual operation. The material is fed into the blanching machine through a mesh belt/conveyor belt or manually. The equipment inside the blanching machine is controlled by frequency conversion, and the blanching time can be set according to different product processes.
2. The machine adopts SUS304 stainless steel plate mesh belt for transmission. The mesh belt has the characteristics of high strength, small flexibility, non-deformation, easy maintenance, etc., the whole machine is balanced in operation and low in noise, which greatly improves work efficiency. When the material is discharged, it is lifted with a mesh belt to directly transport the material out of the equipment. ...
3. The heating source of this machine is steam heating, with automatic control of steam inlet device and surface insulation. Minimize energy waste. ...
4. The transmission system of the machine adopts a speed-adjustable decelerating motor to make the conveying speed of the conveyor belt adjustable, and the blanching time can be adjusted between 3-15min.
