Respond to national environmental protection requirements, and promote the transformation and upgrading of the coating industry with “common factories”
Since the reform and opening up, my country’s economy has developed rapidly. At the same time, some problems that have severely restricted the healthy and sustainable development of my country’s industries have begun to emerge. For example, the production efficiency is low due to the serious redundancy of traditional industrial factories, the increase in the cost of production factors restricts the transformation and upgrading of regional industries, and the serious environmental degradation is difficult to support extensive development. In order to solve such problems, people began to open up a new “road”-the common factory.
At this point, it is necessary for the editor to explain what a generic factory is. The so-called “common factory” refers to an independent legal entity factory that provides intelligent processing services for a traditional industry. It realizes centralized production by gathering the processing links of the same traditional industrial enterprise in this factory. At the same time, the common factory uses intelligent manufacturing technology to realize the technological transformation of traditional industries and form a new, efficient and intensive production model. The most important point is that its emergence solves the problem of high transformation costs for most small and medium-sized enterprises (such as some small and medium-sized furniture companies, home appliance companies, etc.) in the downstream companies of coating .
Take furniture companies as an example: the increased cost is mainly reflected in the recycling of water-based paint in the spraying process. Large companies can basically solve the problem with the funds to buy spraying machines, while small and medium-sized enterprises are relatively laborious. . However, through the construction of “common factories”, it can effectively solve the problems of small and medium-sized enterprises’ VOCs governance difficulties, high costs, and substandard emissions. In addition to the process workshops that use water-based and low-volatility coatings, other related process workshops for solvent-based coatings coating and drying must be phased out and closed before the end of 2020. The processes are concentrated in the “common factory” for processing.
The environmental protection of water-based coatings is obvious, but are there any special requirements for construction tools when switching to water-based coatings? Does it require additional investment? A PPG professional took water-based car refinish paint as an example, and specifically explained the transition from solvent-based coatings to water-based coatings. Additional tools and equipment purchased. A qualified solvent-based coating sheet spraying workshop only needs to be equipped with a special spray gun, a special blow gun and a special gun washing machine for water-based paint under the original equipment conditions to meet the daily needs of water-based paint spraying construction.
In addition, pay attention to the following working conditions: storage-control the storage room temperature range, must be controlled between 5 ~ 35 ℃; paint room-ensure good ventilation conditions and baking temperature; air source-ensure clean, Stable and sufficient air pressure and air volume to supply spray guns and other ancillary equipment; Pre-treatment——Before spraying the base paint, the pre-treatment product D8401(PPG)/P980-8252(AC) should be used to clean the surface; Color adjustment—— It should be carried out in a clean, dry plastic container, and ensure the profile and quality of the plastic so as not to affect the final paint film effect; spray gun-HVLP spray gun or other suitable water paint spraying must be used Special spray gun; cleaning-need to be equipped with a special spray gun cleaning device or equipment for water-based paint; drying-configure corresponding drying equipment according to the number of repairs in the workshop (it is recommended to be equipped with a set of mobile drying equipment and a set of Manual drying equipment); Grinding-a full set of dry grinding equipment is recommended.
Build a generic factory and put the entire production process or certain pollution links into the generic factory, which is convenient for the government to control pollution in the production process, which is conducive to the green production process (such as the use of water-based paint). For example, as the downstream furniture industry in the coating industry, spraying and polishing are the most polluting production links in China. By setting up a common factory for furniture spraying and polishing, the painting and polishing links of all furniture manufacturers are concentrated, so that the environmental impact caused by production The pollution was quickly brought under control.
