Clean workshops are generally closed, with few doors and windows. In the event of a fire, the heat of the flue gas is not easy to radiate outward, resulting in the retention of flue gas, a sharp increase in heat, and more likely to cause injuries and deaths due to high temperature and hypoxia. Therefore, it is important to take fire safety measures. Clean workshop Note 1: In the decoration of clean workshops, we must pay attention to the combustion performance of the decoration materials and minimize the use of some polymer synthetic materials to avoid the generation of a large amount of smoke during the fire, which is not conducive to escape. Note 2: Strict requirements are imposed on the electrical pipelines, and steel pipes should be used wherever possible to ensure that electrical circuits do not become a way for fire to spread. Note 3: Keep the environment clean in the clean workshop. Keep all materials neat and away from heat sources. Pay attention to indoor ventilation. At the same time, ensure that the fire prevention passage in the workshop is unblocked. No items are allowed to be placed at the exits and walkways. Note 4: In the clean workshop, it is not allowed to privately pull the power and wires. If it is really needed, it must be reported to the manager of the production department for approval. It should be handled by the power equipment room and removed in time after use. Note 5: During the operation of oil-fired boilers, inspections should be strengthened, and abnormalities should be handled in time. Note 6: Avoid all kinds of electrical equipment and lines from being wet and overloaded to prevent short circuits from causing accidents. The use of various equipment must strictly abide by the operating regulations, and illegal operations are strictly prohibited. Note 7: The use of open flames is prohibited in clean workshops. If it is really necessary, the consent of the Security Department must be obtained, and it can only be used after effective security measures have been taken. Special persons shall be responsible during the use, and ensure that it is handled properly without hidden dangers after use. Note 8: The clean workshop should be equipped with a gas alarm device, and a gas detector should be installed in the storage and use place. When the gas alarm sends out an alarm signal, it should immediately cut off the supply source, issue an alarm to the site staff, and open the exhaust equipment to exhaust air.

Take bread and cake as an example. Bread and cake are popular foods for consumers, but they are prone to aging, and are easily infected by microorganisms and spoiled. So, how to prevent the mold and mildew problem of bread and cake? We know that the key control points of high-moisture products such as bread and cake are: baking, cooling, and packaging. These three key links. The baking process is actually a sterilization process. When the product is just out of the oven, due to heat radiation, a thermal protective layer will be formed around the product. Generally speaking, fine dust cannot fall on the product. At the same time, due to the very high temperature High, even if it falls, it is not easy to survive. According to production practices, the hygienic condition of the workshop during production is uncontrollable! The reasons are roughly as follows: 1. The floor layout of the workshop is unreasonable; in many small and medium-sized enterprises, the mixing room, the baking room and the cooling room are not completely separated, which causes a large amount of air containing flour particles to fly around while stirring; the flour particles contain a large amount of mold and flour particles Can it fall on the product without mold? 2. The mechanical equipment can not meet the requirements of sterility; especially the ovens (boxes) now basically have the doors open on one side, and they are not designed according to GMP specifications at the time of design. From the perspective of quality management, this equipment guarantees Quality is lacking! 3. The clean area is not clean; if it is not completely isolated, there is no essential difference between the clean area and other areas from a microbial perspective. In addition, the production management is sometimes not in place, and the debris of the dropped products will become a source of transmission due to contaminated mold. This point is that manufacturers with purification workshops must also pay great attention! If a company with a purification workshop still has moldy products, more than 90% are due to this. 4. Production technology is not enough; production technology mainly refers to the usual production management and operation technology, such as sanitary management before and after production, sanitary management during production, and sanitary control procedures and implementation. 5. The formula is unreasonable; when manufacturers use composite preservatives, the proportion of salt, acid, sugar, and oil in the formula must be adjusted to achieve synergistic effects. 6, the management of inner packaging materials: is to be sterilized to a degree of sterilization, generally sterilization with ozone generator is the best. Therefore, food production workshops must meet these standards through purification, which is why more and more people choose to purify. Welcome to visit www.wonclean.com.

Now the competition in the clean room industry is becoming more and more significant, and the clean room engineering industry is gradually changing in three directions.Gradually transform into energy-saving development. First， change from price competition to value competition Nowadays, electronic products are also developing into miniaturization and functionalization, so the reliability requirements of components are getting higher and higher.Then, the electronic information manufacturing industry will be more stringent on the various requirements of clean room standards. In the production process, even trace contamination may cause damage to components and products, which will directly affect the company's benefits.Therefore, the technological development of the electronic information industry promotes the project of clean room from price competition to technology competition. Second，Energy conservation becomes an important goal Clean room project is actually an important energy consumer in China, his consumption of energy can even reach the general office 10 to 30 times.Therefore, many companies will carry out related maintenance on the energy consumption of clean rooms, and suggest to reduce the energy consumption as much as possible.This means an increase in profits for companies.Therefore, the energy conservation of clean room is very important. Third, To advanced clean room technology development Now belongs to the information age of Information, want to stand firm in the society, we must master high-end technology.And air molecular pollution is now a concern.Therefore, the clean room gradually develops to the high-end clean technology, and studies air molecular pollution step by step.For its future development prospects, there is a great help.
At present, there is a great demand for polyurethane sandwich panels in the market, but the huge market for polyurethane sandwich panels is mixed, and the quality of polyurethane sandwich panels is uneven, resulting in the price of polyurethane sandwich panels being also different, but many customers come up to ask how much polyurethane sandwiches are. I. Influencing factors of the lowest price per square meter for polyurethane sandwich panels: fire protection grade of core materials Polyurethane composite panel is divided into three grades: B1, B2 and B3. The amount of black material is the key factor to determine the fire protection level of polyurethane composite board. The more the amount of black material used, the higher the fire-proof grade of polyurethane composite board; conversely, the lower the fire-proof grade of polyurethane composite board. Prices of different fire prevention grades are also different. The higher the fire prevention grade, the higher the price. 2. The Influencing Factors of the Minimum Price of Polyurethane Composite Plate for One Square Meter: Upper and Lower Steel Plates Polyurethane sandwich panel has two layers of steel plate. The price of upper and lower steel plate is affected by thickness,PU sandwich panel manufacturer, galvanized content and other factors. The higher the requirement of upper and lower steel plate, the higher the price will naturally be. 3.
