As we all know, a large number of high-end industries are inseparable from dust-free purification workshop, such as CCL circuit board copper cladding board, PCB printed circuit board, photoelectric LCD and LED, power supply and 3C lithium battery, as well as some pharmaceutical and food industries. With the development of science and technology, the quality standards of supporting products for manufacturing industry have been continuously improved. Therefore, industrial manufacturers not only need to innovate products from the production process, but also need to improve the production environment of products, strictly meet the requirements of workshop environment, improve product quality and stability.
Whether it is the upgrading of existing factories because of the improvement of product quality or the expansion of factories because of market demand, industrial enterprises will face the important problem of project preparation, which is related to the future of enterprises. From infrastructure to supporting decoration, from technology to equipment procurement, a series of complex project processes, in this process, the preparation of the most concerned should be the quality of the project and the comprehensive cost. Following is a brief description of several factors affecting the cost of dust-free purification workshop during the preparation of industrial workshop: space factors consist of workshop area and workshop height, which directly affect the cost of interior decoration envelope structure: color steel plate partition and ceiling area; air conditioning input cost: area volume required for air conditioning load, air conditioning Air supply mode, direction of air conditioning pipeline and number of air conditioning terminals.
In order to avoid increasing project investment due to site, preparation companies can consider two aspects comprehensively: workspace of different production processes and equipment (including height or width margin for mobile, maintenance and maintenance); spatial trend of labor force and logistics. At present, the building follows the principles of saving land, materials and energy. The larger the purification workshop, the better. In preparing for construction, we should consider our own production equipment and technology, so as to effectively avoid unnecessary investment costs.
Temperature, humidity and cleanliness factors:
温湿度和洁净度是为工业产品量身定制的车间环境标准数据，是净化车间最高的设计依据，是产品合格率和稳定性的重要保证。现行标准分为国家标准、地方标准、行业标准和企业内部标准。例如，医药行业的洁净度等级分类标准和GMP标准属于国家标准。对于大多数制造业来说，各生产工艺净化车间的标准主要是根据各自的产品特点来确定的。例如，在PCB行业中，曝光温度和湿度、干膜和阻焊面积分别为22±1℃、55±5%，洁净度在1000 ~ 100000之间。锂电池行业比较注重低湿度控制，一般相对湿度要达到20%，有些相当严格的注塑车间需要控制在相对湿度1%左右。
Temperature, humidity and cleanliness are the standard data of workshop environment tailored for industrial products. They are the highest design basis for purifying workshop and the important guarantee of product qualification rate and stability. The current standards are divided into national standards, local standards, industry standards and enterprise internal standards. For example, the Cleanliness classification standards and GMP standards of the pharmaceutical industry belong to the national standards. For most manufacturing industries, the standards of each production process purification workshop are mainly determined according to the characteristics of their products. For example, in the PCB industry, the exposure temperature and humidity, dry film and solder resistance area are 22, 55, respectively, and the cleanliness ranges from 1000 to 100000. The lithium battery industry pays more attention to low humidity control. Generally, the relative humidity should reach 20%. Some injection molding workshops need to be controlled at about 1% of the relative humidity.
The determination of environmental data standards for purification plants is the most important central point affecting project investment. The establishment of cleanliness level has an impact on the decoration cost: if set above 100,000 level, it requires necessary clean board enclosure structure, air shower room conveying facilities for purifying doors and windows, personnel and articles, and even expensive floor price; at the same time, it also affects the cost of air conditioning: the higher the cleanliness, the higher the ventilation frequency, the air conditioning purification required; The larger the air volume of the air purification cabinet, the more air pipes and efficient air outlets will be added. Similarly, the setting of temperature and humidity in workshop not only has the above cost problems, but also has the factors of control accuracy. The higher the accuracy, the more complete the necessary supporting equipment. If the range of relative humidity is accurate to (+3%) and (+5%), the humidifying and dehumidifying equipment needed to be designed should be complete.
Temperature, humidity and cleanliness of workshop not only affect the investment in the earlier stage, but also affect the operation cost of evergreen plants in the later stage. Therefore, according to the characteristics of their products, combined with national standards, lines and internal standards, formulating reasonable standard environmental data to meet their own needs is the most basic and essential way to purify our factory. The key step.
