LED chips differences
by：Xintao Technology 2020-08-04
At present China LED chip enterprise about ten home or so, late start, the scale is not large enough, the biggest LED chips enterprise output value yuan for about 3, each of the average annual output value in 1 to 2 to.
The two years of mainland China LED chip enterprise develops fast, technical level is soon, small and medium size chip (refers to the following 15 mil) has been able to meet domestic packaging enterprise of basic needs, large size chip (refers to power type W level chip) still need to import, mainly from the United States and Taiwan enterprises, but large size chip only in LED into the general lighting to mass applications.
The performance of the device in LED encapsulation 50% depends on LED chips, LED chip core index including brightness, the wavelength, the failure rate, antistatic ability, attenuation etc. At present domestic LED packaging enterprise of small and medium size chip most choose homebred brand, these domestic brand of chip performance and foreign brands the difference is smaller, has the good price, also can meet the most LED application the needs of the enterprises. Especially the performance of the brand of chips with foreign brand has quite, through the encapsulation technology cooperation, already can meet the needs of many high-end application fields.
Packaging auxiliary material difference
Packaging auxiliary materials including stents, gold line, epoxy resin, the silica gel, the article mould etc. Auxiliary material is the comprehensive performance LED device is an important basis for, the stand or fall of the auxiliary materials can be decided the failure rate, LED device attenuation, optical performance, energy consumption, etc.
At present the mainland of China packaging auxiliary material supply chain has more perfect, most of the material production was on the mainland has been able to supply. But high performance of epoxy resin and silica gel to import the majority, the two types of materials mainly requirement high temperature resistant, resistance to UV, excellent refractive index and good expansion coefficient, etc.
With the global integration process, China LED packaging companies already be applied to the world's newest and best encapsulation auxiliary materials.
Carbon Molecular Sieve for Food Preservation
Food Preservation Nitrogen Generator is a high-purity nitrogen generator specially designed for the food packaging and preservation industry according to the advanced PSA pressure swing adsorption principle, using carbon molecular sieve to separate nitrogen and oxygen from the compressed air. Provide dry and continuous pure nitrogen for food packaging, beverage stirring, fruit and vegetable storage, cereal fumigation, food nitrogen puffing and other purposes , energy saving and so on.
Paint resin industry
Activated molecular sieve power is dehydrated synthetic powerdery molecular sieve. With the character of highdispensability and rapid adsorb ability; it is used in some special adsorptive circumstances, such as being formless desiccant, being adsorbent mixed with other materials etc.
Carbon Molecular Sieve for Nitrogen Tyre Inflator
Xintao's carbon molecular sieve is widely used in nitrogen generator , with high hardness, less ash, uniform particles, and high cost performance. The models selected by customers are usually CMS-240, CMS-260. The nitrogen concentration is 99.5-99.99% and above, which has won a series of praises from customers.
New automatic production line for molecular sieves with an annual output of 5,000 tons
In order to improve the influence and competitiveness of molecular sieve products in the industry, our company has built a new set of zeolite molecular sieve automatic production line with an annual output of 5,000 tons, which has solved the long delivery cycle and instability of product quality for customers.
The packed column used for the separation of distillation is a vertical cylindrical vessel containing an appropriate packing bed supported and irrigated by the liquid flowing through a particular distributor. The bed height is determined by the packing mass transfers capacity and constrained are governed by allowable pressure drop and the overall column height.
Pressure Swing Adsorption (PSA) - Hydrogen Purification
Pressure Swing Adsorption (PSA) from Air Liquide Engineering & Construction is used to recover and purify hydrogen from a variety of hydrogen-rich streams. Xintao 5A Molecular Sieve for hydrogen production, is a special molecular sieves for hydrogen production by pressure swing adsorption.
Molecular Sieve Activated Powder in Polyurethane Industry
XINTAO series molecular sieve activating powder added to polyurethane and other product systems can effectively and selectively absorb trace water in typical polyurethane formulations, inhibit the occurrence of side reactions, thus reducing the generation of bubbles and extending the application period.
PSA nitrogen making
PSA technical(Pressure Swing Adsorption,PSA for short) :it’s a kind of afvanced gas separation technology,based on physical adsorption of gas molecule on the internal surface of adsorbent(porous solid substances),using adsorbents in the same pressure easy to absorb the high boiling point gas,difficult to absorb low boiling point gas.amd under high pressure adsorption amount of absorbed gas increases,under low pressure adsorption of absorbed gas to reduce the features to achieve gas separation.
Application of Alumina Ceramic Balls
Ceramic balls can be divided into ceramic balls and grinding ceramic balls. Ceramic balls are widely used in petroleum, chemical, fertilizer, natural gas, environmental protection and other industries as the cover support material and tower packing of the catalyst in the reactor.
