What is the role of clean type constant temperature and humidity machine clean air conditioner in dust-free workshops in various industries
What is the role of the clean type constant temperature and humidity machine clean air conditioner in the dust-free workshops of various industries. The dust-free workshop is used in many industries, such as spraying workshops, operating rooms, electronic workshops, SMT workshops, biopharmaceutical workshops, food workshops, etc. The division of the workshop level is determined according to the purification level.
The requirements for temperature and humidity in a dust-free workshop are very high. The temperature and humidity requirements of 178 Hangzhou 8821 Songyue 7031 are mainly determined according to the requirements of processing technology. Under the conditions of processing technology, people ’s comfort should be considered first. As the requirements for air cleanliness increase, the process requirements for temperature and humidity are becoming higher and higher, and a certain temperature and humidity level must be achieved.
Therefore, it is necessary to equip a Songyue dust-free workshop constant temperature and humidity machine in the dust-free workshop to regulate the temperature and humidity in the workshop. The temperature and humidity control range of different industries is different according to the materials or production processes, so each dust-free workshop will calculate the model of the constant temperature and humidity machine of the dust-free workshop according to the area and temperature and humidity requirements. Songyue can be based on Require non-standard production of constant temperature and humidity machine in dust-free workshop, welcome to know!
So what is the temperature and humidity control range of dust-free workshops in all walks of life? Let's explain it to everyone below
One: Purify the operating room
The operating room is also a dust-free purification place. The appropriate environmental temperature and humidity are very important for the operator and the patient. When the room temperature exceeds 28 ° C and the humidity is greater than 70% RH, it is easy to have reactions such as sultry, sweating, irritability, fatigue, etc. , It is easy to affect the operator's stable mood and agile thinking, so that the operator's technical level can not be well played. At the same time, the patient will also have symptoms such as fast heart rate and excessive sweating, which increases the difficulty of the operation and brings risks to the operation; when the room temperature is below 20 degrees, the operator wearing only the surgical gown will feel cold and easily affect the sensitivity of the operation Sex and accuracy, especially the subtle movements of the fingers. Naked patients are more prone to cold and other complications due to the low level of trauma resistance.
Therefore, according to the "Consultation Draft for Construction Technical Specifications of Hospital Clean Operation Department", the temperature and humidity of the operating room must be controlled using a dust-free workshop constant temperature and humidity machine to control the temperature and humidity within a certain range: that is, the temperature is 22-25 ℃; the relative humidity is 45 % RH-60% RH.
Two: electronic dust-free workshop
The manufacturing workshop in the electronics industry is a place where static electricity is easy to generate. Generally, static electricity will cause a short circuit to the product or even cause employees to faint. Therefore, the relative humidity of the dust-free workshop in the electronics industry should not be less than 30%, so that the static electricity can be reduced. It is usually recommended that the relative humidity of the anti-static area of ​​the dust-free workshop is not less than 50%. Dust is easy to fly in the too dry air, so if there are no special requirements in the dust-free workshop of the electronics factory, it is generally necessary to use a constant temperature and humidity machine in the dust-free workshop to control the temperature to about 22 ℃ and the relative humidity to 55 to 60% RH In this environment, people feel comfortable and static electricity has disappeared.
Three: SMT clean room
The SMT workshop also has clear requirements for temperature and humidity. First of all, it is mainly for the solder paste to work in a better environment. The temperature will affect the activity of the solder paste, and it will have a certain effect on the activity of the flux-related solvents added inside . High temperature will increase its activity, which will affect the effect of screen printing and reflow. And it is easy to appear virtual welding, solder joints are not shiny and so on.
Humidity will cause the amount of moisture absorbed by solder paste in the air. If too much moisture is inhaled, it will cause air voids, flying, and continuous welding during reflow. Therefore, the constant temperature and humidity machine of the SMT clean room should control the temperature and humidity of the SMT clean room at: temperature 24 ± 2 ℃, humidity: 50 ± 10%.
Four: Biopharmaceutical dust-free workshop
Everyone knows that it is very important to strictly control the quality of medicines, and some even directly affect the life and health of patients. Therefore, in the temperature and humidity control range of the constant temperature and humidity machine in the biopharmaceutical dust-free workshop, the relative humidity requirements for hygroscopic drugs are 45% to 50% RH (summer), solid preparations such as tablets 50% to 55% RH, water injection and oral liquid 55% to 65% RH. This helps to better control the production quality of medicines.
Five: IC clean room
In the lithography exposure process of large-scale integrated circuit production, the difference between the thermal expansion coefficients of glass and silicon wafers as mask materials is getting smaller and smaller. A silicon wafer with a diameter of 100 um, when the temperature rises by 1 degree, causes a linear expansion of 0.24um, so there must be a constant temperature difference of ± 0.1 degrees, and the humidity value is generally low, because people will pollute the product after sweating. Especially for the semiconductor workshops that are afraid of sodium, this kind of workshop should not exceed 25 degrees, and the problems caused by excessive humidity are more. When the relative humidity exceeds 55%, condensation will form on the wall of the cooling water pipe. If it occurs in a precision device or circuit, it will cause various accidents. When the relative humidity is 50%, it is easy to rust. Therefore, the constant temperature and humidity machine in the integrated circuit clean room needs to strictly control the temperature and humidity in the integrated circuit clean room.
Six: food dust-free workshop
The cleanliness requirements in food, health care products, beverages and other workshops are relatively high, usually from 100,000 to 10,000, but at the same time, the lower the humidity in the food-free workshop, the easier it is to breed bacteria, bacteria and other biological pollution (Moulds, viruses, fungi, and mites) can actively multiply in an environment with a relative humidity of more than 60% and some flora can grow when the relative humidity exceeds 30%. Therefore, the constant temperature and humidity machine in the food dust-free workshop should control the relative humidity in the food dust-free workshop to be in the range of 40% to 60% in order to reduce the influence of bacteria and respiratory tract infection to a low point.
