How much does a 100,000-class clean room cost per square meter and what standards do a 100,000-class clean room need to meet?1

How much is one square meter for the decoration of a 100,000-level clean project? The editor of sz-pharma takes the decoration of a 100,000-level clean room in a food and mask factory as an example to explain the construction cost of a clean room in detail. 1. Decoration cost of clean room What factors affect the decoration cost of 100,000-level clean room? It is mainly determined by eleven factors including host system, end system, ceiling, compartment, floor, purification level, illumination requirements, industry category, brand positioning, ceiling height and area. Among them, the ceiling height and area are basically invariable factors, and the other 9 are variable. Taking the host system as an example, there are mainly four types of water-cooled cabinets, direct-expansion units, air-cooled chillers, and water-cooled chillers on the market. Four different units have completely different prices, and the gap is very large. 2. How much is the price for the decoration of the dust-free pharmaceutical cleanroom and how much is one square meter for the decoration of the purification project? Take the clean decoration project of a food factory as an example - SC-level food workshop&Biological pharma machinery: Chuanwei pet food, the project is located in Songjiang, the contract includes office, pharma machinery, clean production workshop, cold storage; the main materials of the project are manual purification board, transparent glass, experimental furniture, etc., and the acceptance has been completed. Generally speaking, our quotation to customers is about 1,500-3,000 yuan/㎡ for a 300,000-level to 10,000-level clean room; however, how much is a square meter for the decoration of a 100,000-level clean room, and the specific quotation is measured and detailed according to the design drawings. The quotation shall prevail, and the above quotation is for reference only. Because the cost of a 100,000-level dust-free workshop is directly related to the size of the workshop area. The cost of a 100,000-level purification workshop with a large number of square meters must be high. However, compared with ordinary civil engineering, the structure of the purification workshop is relatively simple, and the construction cost of the system is low. The 100,000-level purification workshop is relatively easy to expand or rebuild due to the needs of production or operation in the later stage. The materials and pharma machinery selected for the construction of a 100,000-level clean room are also key factors that affect the cost of a 100,000-level clean room. In the 100,000-level purification workshop, a lot of purification pharma machinery is needed, including purification air conditioning system, air shower, transfer window, FFU filter fan, air filter, etc. Depending on the brand of pharma machinery purchased, the cost of the 100,000-level clean room is also different. In addition, the construction of a 100,000-level purification workshop requires the use of other materials, including color steel sandwich panels, doors and windows, clean lighting fixtures, epoxy floors, PVC water pipes, etc. The quality of the materials will also affect the dust-free workshop cost. After the international epidemic broke out in an all-round way, and the “hardness to find a single mask” for domestic masks eased, the concept of overseas mask protection became active. Domestic sales and re-exports may become a new growth point for mask demand. The cost management of the decoration project in the purification workshop has led to many problems; in the decoration and decoration, most of the decoration enterprises attach great importance to the construction management, while ignoring the project cost management, resulting in the incomplete cost management system. , there are many problems in the cost management work. At the same time, many construction enterprises do not have a comprehensive understanding of cost management when they are managing, which makes the stage of cost management immature. In this situation, if there are some emergencies and there is no reasonable planning for them, it will cause a serious waste of funds, and even seriously affect the construction of the entire project. progress is affected. 3. Standard of 100,000-level clean room Class 100,000 clean room refers to the removal of particulates, toxic and harmful air, bacterial sources and other pollutants in the air within a certain space, and the temperature, cleanliness, airflow speed and airflow distribution in the clean room. Indoor pressure, noise and vibration, lighting, static electricity, etc. are controlled within a certain range of requirements, and the designed room or environmental room is of special significance. In addition, no matter how the air conditions outside the workshop change, even if there is thunder and lightning, the interior can also maintain the characteristics of the previously set requirements such as temperature, humidity, cleanliness and pressure. The main function of the clean room is to control the cleanliness and temperature and humidity of the atmosphere that the product comes into contact with, so that the product can be produced and manufactured in a good environmental space, then this space is called the clean room engineering room. The features of the 100,000-level clean room include: 1. Standard cleanliness of the clean room The simple process of LCD screen production is: regular cleaning of the printed alignment film, combined scribing and cutting, LC injection and polarizer film production. This design refers to some dust-free workshops in the terminal process, and its purification cleanliness generally refers to the thousand, ten thousand, and one hundred thousand grades. 2. Requirements for indoor air parameters (1) Requirements for temperature and humidity: the temperature is generally 24+2°C, and the relative humidity is 55+5%. (2) Large air supply volume: In order to balance the cleanliness and heat and humidity in the dust-free workshop, a large air supply volume is required. For example: a pharmaceutical cleanroom of 300 square meters, with a ceiling height of 2.5 meters, if it is 10,000-level , the air supply volume needs to be 300×2.5×30=22500m3/h (the number of air changes is ≥25 times/h); if it is 100,000, the air supply volume needs to be 300×2.5×20=15000m3 The air supply volume of /h (the number of air changes is ≥15 times/h), etc., depending on the different needs of different customers and the customized range is different. (3) Large amount of fresh air: Due to the dense personnel in this type of clean room, the relative value can be selected according to the choice of different customers, and the total air supply volume of the non-unidirectional flow clean engineering room is 10-30%; Compensate the indoor exhaust air and the fresh air volume required to maintain the indoor positive pressure value; and ensure that the indoor fresh air volume per person per hour is greater than or equal to 40m3/h.
