Since the “Weekly Quality Report†of the CCTV on April 15 exposed 13 kinds of chromium super pharmaceutical capsule products from 9 companies, the “toxic capsule†incident continued to ferment. In the past few days, various provinces and municipalities quickly launched an investigation into the issue of capsules for encirclement problems. Both the small and large companies in the gelatin industry as raw materials for capsule production have encountered an unprecedented crisis of confidence. People in the industry have stated that they should strengthen supervision and make up loopholes in chemicals that are closely related to the food, clothing and housing of the ordinary people. As the protagonist of this "toxic capsule" incident, the gelatin industry is facing a storm of turmoil, or will usher in an industry reshuffle. According to the CCTV “Weekly Quality Reportâ€, companies such as Xueyang Gelatin Plant in Luancheng County in Hebei Province and Guifeng Gelatin Factory in Luyang County in Jiangxi Province sold industrial gelatin produced from leather waste to the “hometown of capsulesâ€. The capsule manufacturing company in Xinchang County, Zhejiang Province, successfully made hollow capsules with excessively high chromium content into pharmaceutical factories throughout the country, and eventually became the market for capsule drugs of various brands. After the incident was exposed, the State Food and Drug Administration immediately issued an emergency notice requesting suspension of sales and use of related products. After the supervision and inspection and product inspection results are clear, qualified products will continue to be sold, and unqualified products will be handled according to law. Enterprises that produce and sell medicinal hollow capsules in violation of the regulations will be severely investigated and dealt with according to law. On April 16, the Tancheng County government stated that the local gelatin production and operation enterprises will be suspended from rectification, all illegal production enterprises will be banned, their production facilities destroyed, raw materials and products will be sealed on the spot, and the relevant departments shall promptly Sales are tracked down. Yao Longkun, general secretary of the China Daily Chemical Association Gelatin Section, said that the behavior of a few companies has seriously disturbed the gelatin market order, and at the same time it has caused great negative impact and losses on the regular gelatin production enterprises, which has greatly hurt the credibility of the entire industry. According to industry insiders, the use of industrial gelatin as a raw material for medicinal capsules is driven by the interests of the company and has not strictly implemented the relevant standards for pharmaceuticals, and the relevant departments have neglected the supervision. The price of 1 ton of edible animal collagen material animal bone skin is between 2000 and 3,000 yuan, while that of industrial leather waste (commonly known as "blue tanned skin") is only 100 to 200 yuan. Gelatin production is the most lucrative link in the entire chain and the source of security incidents. Song Ruilin, executive director of the China Pharmaceutical Pharmaceutical Policy Research Center, said that as of now the country has not managed the production of medical excipients. In order to ensure that the production and sales of the gelatin industry are legally compliant, GMP certification should be carried out by the gelatin production enterprise, and the act of imitation of pharmaceutical gelatin by industrial gelatin should be eliminated from the source. People in the industry generally believe that with the increase in the community’s appeal for improvement in the gelatin industry, industry reshuffle will be inevitable, small-scale enterprises will lose their markets, and large-scale enterprises will reintegrate resources to further expand production capacity and markets.
1.Welding materials
In
Welding, substances called filler materials or consumables are used. As the
name implies, these substances provide filler or a body of molten materials
that provides a strong bond to be formed between the base metals used. Most
welding processes will also require some form of shielding to protect both the
main components and filler from being oxidized during the process.
The
type of welding materials used during welding depends on the nature of the job
intended. Electrodes draw the necessary energy in order to perform welding
applications. Luoyang Golden Egret Company has any kind of welding materials
include CTC Welding Rod /rope, SCTC welding rod/rope, TC electronic welding rod,
Ni-based welding rod, flux-cored Welding Wires, solid welding wires and etc.
Welding

construction, oil and gas, marine, power generation, steel, mine tools,
automobile, transportation and etc.
2. Welding rod
1)Cast tungsten carbide based tubular
rod
