Services: technical development and services of functional films; Wholesale and retail: hardware and electricity, plastic products, chemical business scope, fiber and textile; Import and export of goods (except for items prohibited by laws and administrative regulations, and items restricted by laws and administrative regulations can be operated only after obtaining permission). (for projects subject to approval according to law, business activities can be carried out only after approval by relevant departments)
2、 Main business of the issuer
The issuer is mainly engaged in the R & D, production and sales of differentiated and functional biaxially oriented polyester film (BOPET film).
3、 Core technology and R & D of the issuer
(I) core technology
Since its establishment, the company has been committed to the R & D, production and sales of differentiated and functional polyester film. Through continuous independent research and development, the company has formed core technology systems such as biaxially stretched colored film manufacturing technology, colored film formula technology, multifunctional window film base film manufacturing technology and flame-retardant polyester film manufacturing technology, which has comprehensively improved production efficiency, product quality and performance. The core technologies of the company’s main products are as follows:
Serial number core technology features specific application
Through the control of various process links of biaxial stretching production process, including blue, red and biaxial stretching with ingredients, plasticizing extrusion, melt pressure, casting process, longitudinal drawing process, golden yellow, black and white film manufacturing, transverse drawing process and thickness measurement feedback, it is ensured that the color of colored optoelectronic based technologies such as colored polyester film has good uniformity and stability, Film production while maintaining thickness
stability
Through the allocation of the type and amount of Color Masterbatch, based on the basic principle of three primary colors, it is used for the formulation design of blue, red and 2 colored films. Combined with the color difference instrument and gloss instrument, it can realize the regulation of the color and luster of gold yellow, black and white colored films, and control the color and other colored optoelectric base color difference of different batches of colored films, Ensure the stability of color and luster of colored film and film production
1. The multifunctional window film base film is used in the preparation of BOPET film
Color, heat insulation, UV protection and other functions endow the film, which is made of traditional window film
Compared with the preparation method, it can effectively avoid volatile organic compounds (VOC) and make the window film
The production process of multi-functional window film can be reduced and the energy consumption in the production and manufacturing process can be significantly reduced. It is used for UV barrier and red 3 base film manufacturing technology. 2. The heat insulation effect can be adjusted according to the use needs. The maximum heat insulation effect of external barrier and different light transmission results can reach 95%, which can achieve the effect rate of energy saving and environmental protection. Window film and building explosion-proof 3. It can block the ultraviolet of the whole band, Especially the production of 360400 nm film
The UV blocking rate of the band can reach 100%, which can be reduced to the greatest extent
UV damage to human skin
4. When applied to architectural glass, it can play a safe and explosion-proof effect
Halogen free flame retardant system conforming to RoHS and reach standards is adopted, combined with
ABA three-layer coextrusion technology, the flame retardant polyester film developed by the company is used for the flame retardant of transparent, black and 4 flame retardant polyester film, the grade can reach the flame retardant grade of vtm-0 in the American UL94 standard, and the manufacturing technical results of flame retardant film such as flame retardant effect white have passed the American UL certification (yellow card No.: e516097); Adopt special production
Special production technology can maintain the temperature resistance, mechanical strength and
The insulation and other properties are consistent with those of ordinary polyester film
Through the selection and combination of opening agent, the formulation of high-definition opening agent is formed for the production 5 technology system of high-definition film. Through the regulation of winding process, the dosage of opening agent is further reduced to produce high-definition film
The haze of the film is less than 1% and the definition is more than 99.00%
Different types of resin blending and the addition of functional additives are used for the modification of high-strength and high elongation 6 PET film to improve some physical properties of pet, such as strength, elongation, elongation, high temperature resistance and other technology, and the production of differentiated polyester film such as temperature resistance
The technology uses special anti aging additives and anti hydrolysis additives.
During the preparation of Cecep Solar Energy Co.Ltd(000591) backplane BOPET, through the control of production process, the
7. Crystal perfection of special polyester thin liter polyester molecular chain.
Compared with the manufacturing technology of ordinary polyester film used for Cecep Solar Energy Co.Ltd(000591) back sector film, it has the characteristics of low shrinkage and low water vapor transmittance, and has the advantages of film manufacturing
Excellent aging resistance (PCT test for 48 hours) to meet Cecep Solar Energy Co.Ltd(000591)
Requirements for use of membrane for back sector.
