Nucleic acid test paper is required in the process of nucleic acid detection. This kind of test paper developed in China is specialized in nucleic acid detection. It only takes 3-15 minutes to detect whether the patient has virus. The test paper is not the paper we often use, but a complete set of test materials including sample pads, connecting pads, fiber membranes and adsorption pads.
In order to detect no problems, it is necessary to ensure the quality of nucleic acid test paper. Once it is polluted, the detection effect will be greatly reduced. If patients are not found due to the quality of test paper during the detection process, it is not conducive to epidemic prevention and control.
Nucleic acid test paper production needs to be carried out in a clean environment. Every time an employee enters the factory for work, he/she should first use the induction hand washing device to clean his/her hands, blow dry his/her hands, then go to the special dressing area, wear a head cover, mask, one-piece dust-proof clothes and dust-proof shoes, and then use the induction device to disinfect. The sole of the shoes can only enter the operation area after another dedusting. The level of the clean workshop is at least 100000, and there are strict restrictions on the number of dust, microorganisms, floating bacteria, etc., especially in the humid environment.
Because the fiber membrane in the test paper is very sensitive to air humidity, it is easy to absorb moisture in the air, which will lead to incorrect detection effect. For the nucleic acid test paper production workshop, the air humidity needs to be controlled below 30% RH, so how can the nucleic acid test paper workshop control the air humidity? As we know, most enterprises use refrigerated dehumidifiers for moisture-proof and dehumidification, but they cannot use them in the nucleic acid test paper workshop. Because refrigerated dehumidifiers cannot reduce the air humidity below 30% RH, they can only use rotary dehumidifiers.
Ansiman rotary dehumidifier is made into honeycomb by using silica gel, molecular sieve and other hygroscopic agents. The rotary wheel is divided into 3/4 moisture absorption zone and 1/4 regeneration zone. In the two isolation areas, when the treated air passes through the moisture absorption area, the moisture absorbent will adsorb and dehumidify it, and the blower will send the drying air indoors. At the same time, regeneration air (heated by electricity or steam) is sent in the opposite direction to desorb and regenerate the runner in the regeneration area, and the moisture absorbed by the runner is discharged in the form of steam. At normal temperature, i.e. 20~25 ℃, the activated silica gel dehumidifier runner is used in the occasions where the humidity requirement is 10%~50%, while the molecular sieve dehumidifier runner is used in the special process occasions where the temperature and humidity requirement is 1%~10%, and the relative requirement is very strict. The dehumidifier can meet the requirements of moisture-proof and dehumidification for nucleic acid test paper workshop.
Ansiman rotary dehumidifier adopts patented double frame design of anti cold bridge, with simple and exquisite frame structure, dignified and generous appearance and strong air tightness; The interior of the unit is flat, not easy to accumulate dust, and free of secondary pollution. It is suitable for moisture and dehumidification in the sterile workshop of the purification workshop. The unit adopts a dehumidification waste heat recovery system to improve the regeneration capacity and reduce the regeneration temperature to ensure energy-saving operation. High quality accessories are selected for fine production with unique process; Ensure the quality of the unit, with good dehumidification effect, simple structure, stable operation, convenient maintenance, and good moisture-proof effect for nucleic acid test paper workshop.
