Dyeing and pigment industry focuses on intrinsic safety

On September 14, the 2nd National Symposium on Safe Production of DyeIng Pigment Additives was held in Hangzhou. "Safe production is vital to all enterprises, is the basic guarantee of the survival of enterprises, can not be overemphasized." Shi Xianping , president of the China Dye Industry Association , said that China

of the 18 key regulatory dangerous chemicals process lists, 7 are closely related to the dyeing pigment industry, of which 5 are related to intermediate production and 2 are related to the final product. Intrinsic safety is particularly important in the dyeing pigment and additive industry. Hangzhou Lily Clariant Pigment Co., Ltd. General Manager Ma Guidemin told reporters.
Shi Xianping illustrates the importance of safe production by taking the traditional kettle nitrification process as an example. The process equipment, are using a single pot intermittent reaction; Once the traditional intermittent process encounters the rapid rise of the medium temperature in the reactor, it is very easy to have safety accidents; The number of operators is large and can cause very serious injuries in the event of an accident. Therefore, the industry needs to pay more attention to production safety.
Xubin, deputy general manager of Zhejiang Longsheng Group Co., Ltd., gave a personal opinion on "what is a safe technology" which is widely questioned by enterprises. He believes that there is no absolute safety process. Do a safety establishment, expert evaluation report process, do DCS self-control device, with SIS system facilities, do thermal safety risk assessment process is a safety process? In fact, it is not, because these can only strengthen the identification of risks, in advance to check the hidden dangers of accidents. Only when the whole enterprise really attaches importance to safety, and put it into practice, can the accident be stopped in time when the risk comes.
Shi Xianping pointed out that essential security embodies the concept of "prevention over cure". Each dye pigment additive manufacturer should rely on science and technology to implement essential safety, but also to consider the cost, product quality and long-term stable operation of the device and other factors.
can we be essentially safe? Shi stressed that the first is to minimize the amount of substances and energy contained in the process, such as the reaction does not use volatile solvents, or the use is very small. Second, the use of low-hazard substances or process conditions instead of high-hazard substances or process conditions, such as the use of low-volatile solvents instead of highly volatile solvents. The third is to design simple processes, such as removing cumbersome facilities and controls based on chemical physical characteristics. Fourth, to stay away from the source of hazards, reduce the accident on the human body and the surrounding environment, such as the use of automatic control instead of manual operation, enterprise into the park.
meeting was chaired by Kang Baoxiang, Secretary General of the China Dye Industry Association. Lu Ingming, Secretary General of the China Chemical Safety Association, introduced the construction of risk classification control and risk detection and control mechanisms for chemical enterprises, and experts from the Chemical Registration Center of the Ministry of Emergency Management and business representatives shared their experiences in safety management and related accident cases.
