1. Buy pesticides should go to the designated pesticide distribution department, such as agricultural technology stations and supply and marketing cooperatives. 2. See if the contents of the pesticide label are complete. Such as pesticide name, pesticide three certificates (pesticide registration certificate, pesticide production license, pesticide production implementation standards), loading, use instructions, precautions, production date or batch number of factory names and detailed addresses, etc., counterfeit biological pesticides are often incomplete. 3. Look at the appearance. (1), powder, wettable powder, should be loose parts, no agglomerates. (2) The emulsifiable concentrate should be a homogeneous liquid with no visible foreign matter. If stratification or turbidity occurs, or the milky liquid is uneven after adding water or there are oil slicks, sediments, etc., and can be regarded as inferior pesticides. (3) The suspending agent should be a flowable suspension without agglomeration. (4) If the tablet for the fumigant is a powder, it indicates that it has failed.

The service life of aluminum sliding windows is affected by many factors:
1. Material quality
Aluminum alloy profiles
If high-quality aluminum alloy profiles are used, the wall thickness meets the standard and the alloy composition is excellent, its service life can reach 30-50 years or even longer. For example, some high-quality aluminum alloy profiles such as 6063-T5 have strong corrosion resistance and deformation resistance.
Hardware accessories
Hardware accessories such as pulleys, handles, locks, etc. have a greater impact on the overall life. Good quality stainless steel or copper hardware accessories can be used for 10-20 years under normal use. Cheap and low-quality hardware may be damaged in 5-10 years, such as pulley wear leading to poor sliding and pulling.
2. Use environment
Climatic conditions
In dry and mild climates, aluminum sliding windows have a longer service life. However, if they are located in coastal areas, high humidity and high salt air will accelerate the corrosion of aluminum alloys, which may shorten the service life to about 20-30 years; in areas with more acid rain, it will also cause erosion on its surface.
Daily maintenance
Regular cleaning, maintenance, and timely replacement of aging parts of aluminum sliding windows will greatly extend their service life. On the contrary, if there is a long-term lack of maintenance, the life of the window may be reduced by 5-10 years.
