Hardeners, also called hardeners, are substances or mixtures that enhance or control curing reactions. Curing agent is an essential additive. Whether used as adhesive,
coating or castable, curing agent should be added, otherwise Epoxy Resin
can not be cured. Resin curing is a process of irreversible change of thermosetting resin
through condensation, closed-loop, addition or catalysis and other
chemical reactions. Curing is accomplished by adding curing
(crosslinking) agent. The kinds of curing agent have great influence on the mechanical
properties, heat resistance, water resistance, corrosion resistance and
so on. Curing Agent,Epoxy Curing Agent,Amine Curing Agent,Sodium Silicate Curing Agent Jiangyin Thousands Chemicals Co. , https://www.wqhxcomposite.com
For a long time, the LED lighting market has been accused of disorderly competition. Due to the lack of upstream core technology, this young emerging market is deeply immersed in homogenization and competition. Dachang small factory can produce, and then fight the price. This is the helpless voice of a listed company's technical staff.
For a long time, the LED lighting market has been accused of disorderly competition. Due to the lack of upstream core technology, this young emerging market is deeply immersed in homogenization and competition. Dachang small factory can produce, and then fight the price. This is the helpless voice of a listed company's technical staff.
LED lighting standards for several months, the EU and the United States imported product standards to add to the LED lighting industry, adding to the glory of the LED lighting industry, which means that the country's more than 8,000 LED companies will be more difficult to export. Competing domestically, big manufacturers can't beat the price of small factories, and small factories will soon die; competing abroad, products are not up to standard, causing exports to be blocked, and the market is difficult to collect.
In this context, the establishment and standardization of standards began to be called by more people. At the same time, the government is making efforts. Last month, the “Guangdong Province LED Benchmarking System Recommended Product Catalogue†was released, which shows that the industry is calling for a more orderly and healthy market.
How to unify the standard of uneven LED lighting standards Recently, the reporter conducted an exclusive interview with Mr. Guan Junchao, Director of SGS China Consumer Electronics Division at the Shenzhen New Standards Analysis Seminar, to bring you the latest interpretation of LED lighting standards.
Testing new features The reporter learned that for the LED lighting principle, the detection requirements for overload status and photobiosafety are particularly strict, which is also the difference between incandescent and energy-saving lamps. The detection of LED luminaires must be considered in terms of safety, performance and energy efficiency.
In theory, LEDs can achieve a lifetime of up to 50,000 hours, while incandescent lamps are only 1500 hours. However, the LED lamps sold on the market are not good enough. Many consumers have changed the lamps to LED products at a high price. Not only do they not expect to be efficient and energy-saving, on the contrary, they often appear in less than a few weeks without illuminating or stroboscopic.
Guan Junchao told reporters that these are all negative examples of quality. Each test has corresponding content and indicators, strict implementation, product quality will be greatly improved: only energy efficiency test, including light efficiency, energy efficiency index, 6000 hours residual rate, 6000 hours lumen maintenance rate, life The number of switching cycles, start-up time, warm-up time, premature damage rate, color rendering index, color stability, power factor, etc., not to mention other test items. These must be strictly monitored to ensure that the lighting products are qualified.
New environmental protection requirements last month, the recovery of energy-saving lamps is difficult to sequelae. Based on this, the environmental performance of LEDs was again raised. Because of the different principles of luminescence, LEDs do not cause mercury pollution, but it does not contain other harmful substances, but it is difficult to say. Will it take the old road of energy-saving lamps and have to check it out.
Guan Junchao said: In Europe, the WEEE Directive and the RoHS Directive have been mandated to detect discarded electronic products and the toxic substances they contain. On July 1, 2011, the EU issued a new version of the RoHS Directive 2011/65/EU, which was enforced on January 3, 2013. The WEEE Directive also issued a new version on July 4, 2012, and was enforced on February 14, 2014.
This means that if China's LED lamps are to be exported, they must meet the technical indicators of these two aspects. And this will not only be an international requirement. With the development of the LED lighting market, domestically, there will be similar requirements for LED lighting products in environmental protection.
At the current stage of detecting the unevenness of consciousness, China's LED lighting inspection is divided into mandatory and voluntary according to the category of the lamp itself and the regulations of different regions.
After interviewing a number of LED business stakeholders, the reporter found that many LED lighting companies will voluntarily strictly implement non-mandatory testing. In their view, although this will increase part of the cost, it is more conducive to gaining consumer trust and is more conducive to entering the international market.
What about the company’s participation in testing? Guan Junchao said that the detection consciousness of enterprises is uneven. Relatively speaking, large-scale enterprises and well-known enterprises pay more attention to detection and quality improvement.
When talking about the problems in the inspection and the expectations of the company, Guan Junchao said: Customers generally have a headache for the unqualified problems in the testing process, and the rectification reaction is slow, so the whole testing process will be prolonged. It is hoped that enterprises can pay attention to the cultivation of professional testing talents and better cooperate with testing institutions to complete tests quickly and efficiently, and to obtain more and larger business opportunities.
How to unify the standard Today, although there are more than 8,000 LED companies nationwide, more than half of them do not have their own core technologies. And many LED manufacturers' upstream, middle and downstream products have not been integrated. If it is detected, the imported and domestic products are mixed together, and the parts produced by different manufacturers are mixed together. Will the standard be unreasonable?
Guan Junchao said that if it is based on standard testing, the difference between standards will not be too large. Because most areas of testing standards are in line with the IEC standard system. North America has its own standards, but some projects of the IEC standard are also used, or many test items are the same as the IEC standards, so the test items and methods are similar.
In addition, the lack of core technology of LED lamps has directly led to the rise in prices. Today, LED companies have not yet entered the civilian market on a large scale. Will LED lighting inspections be different in commercial and residential areas?
Guan Junchao explained that the testing standards are divided according to the specific use occasions and installation methods of the products, and are not divided by commercial and civilian. For example, an embedded LED downlight, the standard used is IEC60598-2-2, if you use it in the mall or factory floor, it is commercial, and it is used for civilian use in the residents' home, but the testing standards are exactly the same.
