A mosquito repellent, the cigarettes emitted after litting the drugs can drive away mosquitoes or smoked mosquitoes.There are very long history of mosquito coils in my country.Today, I will introduce the principles and types of mosquito coils. Lets take a look!
What are the types of mosquito coils
Mosquito coil
There are two types of scent and scent, and liquid or solid electric mosquito coils appear later.
Disk -type mosquito coils:
Advantages: ① The pesticides of mosquito coils can be adjusted at will, mosquitoes are not easy to adapt, and mosquito mosquitoes are effective; ② pesticides are evenly distributed on mosquito coils, use gradually heating, insecticides are waving uniformly, and mosquito efficiency is stable and stable.The KT50 value is consistent; ③ no power supply; ④ the price is cheaper.
Disadvantages: ① The fixed use time cannot be guaranteed;It is too late to disperse (especially the tray mosquito coils produced by traditional craftsmanship), about 30-40%of the pesticides are heated and decomposed, losing the effect of driving mosquitoes; ⑤ need to invest a large amount of equipment, build a large factory building and use a large number of large amountsLabor; ⑥ consume a lot of precious wood resources.
Electric Mosquito Mosquito:
Advantages: ① smoke -free, odorless, ash, no pollution; ② use PTC heating sources, safety and hygiene; ③ products are easy to transport.
Disadvantages: ① The effect of driving mosquitoes is unstable. The first 4 hours before, after 4 hours, the effect of driving mosquitoes gradually decreased;In fixed heating, the decomposition rate of pesticides is high; ④ The paper base after use still has 20-30%pesticide residual, losing the effect of mosquito, causing waste, and polluting the environment; ⑤ 5W/H consumption 5W/hEssence
Electric heating liquid mosquito coils:
Advantages: ① smoke -free, odorless, ash, no pollution; ② use PTC to heal source safety; ③ use time to do whatever you want, send electricity at time, and disconnect at time without time. It is very convenient to use.A bottle of potion can be continuously used for 300h (affected by the PCT temperature); ④ can be produced without mechanical equipment.
Disadvantages: ① Due to the inadequate boiling point and steam pressure of the ingredients in the pharmaceutical agent, it cannot evaporate simultaneously during heating, causing the core rod to block.② The pharmaceutical formula cannot be adjusted at will, and a single formula mosquito is easy to adapt; ③ During the use process, the decomposition rate of pesticides is about 30-35%.All, all greatly reduce the utilization rate of pesticides, cause waste, and pollute the environment; ④ 5W/h; ⑤ The solvents are deodorant kerosene, the medicine bottle is difficult to seal, leakage, and coal oil is a dangerous goods, which is inconvenient to transport.
Electronic mosquito
Based on the rapid development of electronic products such as computers and mobile phones, electronic mosquito coils appeared.Electronic mosquito coils are different from traditional electric mosquito coils. It is a software developed for computer and mobile phone users. According to the mosquito life characteristics and physiological characteristics, it can effectively repel mosquito repellent.[2]
Principle and composition of mosquito coils
The principle of solid electric mosquito coils is to inhale pesticides (ex -chrysanthemum essence) into paper slices, and use the heat to evaporate pesticides. Generally, the efficacy can be maintained for 6 to 8 hours.The disadvantage is that the medicinal effect is good when it is used, and there may be "overlords", but after 4 to 5 hours, the pesticides volatilize, the effect of the effects is poor, and the effect of mosquito prevention becomes weakened.
The liquid electric mosquito coil uses the principle of capillary and continuously heating to release insecticides, which can make up for the shortcomings of electric mosquito coils.The liquid electric mosquito coil can be used for a long time, about 60 days, and it can even be released regularly.
Mosquito coils use high temperature combustion effects to slowly release pesticides into the air. The effect of mosquito repellent is greater than the effect of mosquito killing.
What are the harm of mosquito coils
The effective ingredients of most mosquito coils are insecticides, as well as organic fillers, adhesives, dyes, and other additives. The burning smoke of mosquito coils contains many harmful substances to the human body, which may induce asthma and other diseases.
According to estimates, the amount of particles released by a roll of mosquito coils and the amount of cigarettes of about 100 cigarettes are roughly the same. The release of ultra -fine particles can enter and stay in the lungs. In the short term, it may cause asthma, and it may cause cancer in the long run.Secondly, the carcinogenic substances caused by incomplete combustion of mosquito coils, and some compounds that stimulate the upper respiratory tract, these substances can poison the nervous system.
