What are the classifications of clean rooms?
A clean room refers to a space with good airtightness that controls air cleanliness, temperature, humidity, pressure, noise and other parameters as needed psb (15) Cleanroom Classification According to the flow state of airflow According to the flow state of the airflow, there are mainly the following three types of clean rooms with airflow distribution [1] (1) Non-unidirectional flow clean room: It is often called a turbulent clean room before, and the airflow in the room does not all flow in a single direction. Non-unidirectional flow clean rooms have several common characteristics: the terminal filter (high efficiency or sub-efficiency) is as close as possible to the clean room, it can be the air supply port or directly connected to the air supply port, or it can be connected to the air supply static plenum in the room. ; The return air outlets are located in the lower part of the clean room, in order to avoid the phenomenon of "ashing". There are eddy currents in non-unidirectional flow clean rooms, which are not suitable for clean rooms with high cleanliness, but should be used in clean rooms of class 6 to 9. (2) One-way flow clean room: The air flow of one-way flow clean room is characterized by parallel streamlines, flowing in a single direction, and uniform wind speed on the cross section. There are vertical one-way clean rooms, quasi-vertical one-way flow, and horizontal one-way flow. Convective clean room, etc. (3) Vector clean room: air is supplied at the upper corner of the room, using a fan-shaped high-efficiency filter, or an ordinary high-efficiency filter with a fan-shaped air outlet, and a return air outlet in the lower part of the other side, the height of the room is higher than normal It is appropriate to be between 0.5 and 1. This clean room can also achieve Class 5 (Class 100) cleanliness. The flow pattern of the clean room is basically the above three types, but many forms can be evolved in practical applications. The clean room can be a mixed flow pattern combining unidirectional flow and non-unidirectional flow to achieve a high level of clean room in a localized area (unidirectional flow section). For example, a "tunnel" (one side is open) with horizontal unidirectional flow is set up in the clean room, and the rest of the clean room is a unidirectional flow pattern of eddy current, so that the "tunnel" part can achieve a cleanliness level of 5 or higher, and the workbench Right in the "tunnel". By properties of controlled particles (1) Industrial clean room: a clean room in which the controlled particles are non-biological particles such as dust. (2) Biological clean room: a clean room in which the controlled particles are biological particles.

VHP Hydrogen Peroxide Low Temperature Plasma Space Sterilizer

Time of issue : 2022-03-26 15:35:34

VHP hydrogen peroxide low temperature plasma space sterilizer is mainly used in clinical medical equipment that meets the requirements of medical materials and geometric shapes. As long as it is used according to the requirements, the sterilizer can reach the sterilization level of 10-6SAL. The hydrogen peroxide low-temperature plasma sterilizer can perform low-temperature sterilization of metal medical devices and low-temperature sterilization of non-metal medical devices. Medical devices are sterilized by diffusing hydrogen peroxide within the chamber, which is then "energized" into a plasma state. Combined with plasma, hydrogen peroxide vapor can safely and rapidly sterilize medical instruments and materials without leaving toxic residues. All stages of the sterilization process are run in a dry, low temperature environment so they will not damage instruments sensitive to heat or moisture, work with both metallic and non-metallic instruments, and allow hard-to-reach items such as hemostat hinges (not easy to spread). ) to sterilize the parts of the instrument. The first company to introduce plasma sterilization technology was Johnson & Johnson of the United States. At present, domestic manufacturers such as Beijing Kesp, Chengdu Laoken, and Shandong Xinhua are well-known. Hydrogen peroxide plasma is a new low-temperature sterilization technology that was introduced in the 1990s. Plasma is considered to be the fourth state besides liquid, gas and solid. It is formed by the excitation of gas molecules in an extremely vacuum cavity. Hydrogen peroxide plasma sterilization has the advantages of short sterilization cycle time and complete decomposition of the final product with low toxicity. However, due to the contamination of Mycobacteria tuberculosis, the US FDA has not approved the use of a diffusion enhancer to solve the problem of the difficulty of hydrogen peroxide vapor penetrating long and narrow lumen items.

The dust particle counter corresponds to the particle size and the pulse voltage one by one

Time of issue : 2022-03-26 15:34:54

Use a dust particle counter to detect whether the filter is leaking to avoid air filter leakage and affect the entire production. The dust particle counter mainly detects whether the suspended particles at each point exceed the required range of the clean area. If so, there is a leakage phenomenon, which needs to be plugged or replaced. This is also a relatively simple and accurate method of operation. After the filter is installed or replaced, the installation and connection of the filter must be checked for leaks to ensure that the cleanliness of the clean room meets the requirements. After the particles of different particle sizes are converted by the photoelectric system of the laser dust particle counter, electrical pulse signals of different amplitudes (voltages) will be generated. The larger the particle size, the higher the pulse voltage. The relationship between signal voltage and particle size is also called conversion sensitivity. For a given laser dust particle counter, the particle size and pulse voltage correspond one by one. For example, the conversion sensitivity of a laser dust particle counter is 0.3μm corresponds to 69mv, 0.5μm corresponds to 531mv, 1.0μm corresponds to 701mv, etc. If the particle counter detects a pulse of 100mv, the particle size must be greater than 0.3μm and less than 0.5μm. The laser dust particle counter is an instrument that measures the number of particles greater than or equal to a certain particle size, and its internal circuit is a circuit that counts the number of pulses greater than or equal to a certain voltage value. For the example in the previous paragraph, to measure the number of particles greater than or equal to 0.3μm in the air, in the circuit is to count the number of pulses greater than or equal to 69mv, and to measure the number of particles greater than or equal to 0.5μm, in the circuit is to count the number of pulses greater than or equal to 0.5μm is the number of pulses of 531mv, and so on. Therefore, the measurement of dust particles by the dust particle counter mainly depends on the parameter of conversion sensitivity.
