The installation and selection of sticky insect tape in glass greenhouses is crucial for ensuring the healthy growth of greenhouse crops and reducing the use of chemical pesticides. The following explains the selection criteria, installation methods, and precautions: 1. Sticky Insect Tape Selection Criteria Material and Durability Aging Resistance: Given the high temperature and humidity in greenhouse environments, UV-resistant and corrosion-resistant composite materials (such as PPE) should be used to prevent cracking or adhesive loss after long-term use. For high-quality, long-lasting sticky insect tape, the application rate should be ≥ 70 grams per square meter to ensure that the adhesive strength does not significantly decrease within one year, maintaining high trapping efficiency. Targeted Insect Attraction Color Classification Yellow sticky tape targets yellow-feeding pests such as aphids, whiteflies, and leafhoppers and is suitable for most greenhouse crops. Blue sticky tape targets blue-feeding pests such as thrips and should be used alone or in combination depending on the greenhouse pest species. A double-sided adhesive design improves trapping efficiency. The adhesive layer should be evenly applied and free of bubbles to prevent pest escape. Environmental Protection and Safety Choose non-toxic, non-polluting, and environmentally friendly glue to avoid harm to crops or operators. Sticky...

01 Film Materials Conventional Plastic Film (PE/PVC) Replacement Cycle: Conventional PE or PVC film has a service life of approximately 6 months to 1 year. Due to the rapid decline in light transmittance and drip resistance in actual production, annual replacement is recommended. Special Scenarios: For high-light crops (such as nightshade vegetables), prioritize replacing aging film to prevent light transmittance from falling below 70%, which can affect photosynthesis. Functional Film (EVA/PO Film) EVA Film: Offers excellent durability and is recommended for replacement every 2-3 years. PO Film: Highly resistant to aging, with a service life of up to 2-3 years. Replacement is recommended when light transmittance drops below 80%. PVC Calendered Film Due to its susceptibility to aging and poor dust resistance, replacement is recommended every 1-2 years. 02 Hard Materials Glass Single/Double Glazing: Chemically stable, maintains a light transmittance above 91.5% over a long period of time. With normal maintenance, it can last 20-30 years, requiring only periodic cleaning or repairs. Ultra-clear diffuse reflective tempered glass: Has a higher light transmittance (97.5%) and requires less frequent replacement, but requires regular crack inspection and sealing. PC Sheet Strongly impact-resistant, with a service life of 10-15 years. Replacement is required if...

How to clean and maintain greenhouse covering materials? Greenhouse Covering Material Cleaning and Maintenance Guide 01 Cleaning Methods Film Materials General Cleaning: Use a long-handled soft-bristle brush or high-pressure water to remove surface dust. Cleaning should be done on sunny days during the afternoon or afternoon when temperatures are higher. Stubborn Stains: Avoid scratching with hard objects. Use a neutral detergent to assist in wiping. Avoid using corrosive chemicals. Light Transmission Restoration: Regular cleaning can reduce the loss of light transmittance (approximately 10%-20%) and maintain normal crop photosynthesis. Glass Materials Daily Cleaning: Use a soft cloth or rubber scraper to remove surface dust and water stains. Avoid using hard brushes or acidic cleaners to prevent scratches or corrosion. Deep Maintenance: Use a high-pressure water jet to clean glass and gutter sludge every 2-3 months. Check for cracks and repair them. Hollow Board/Plastic Board Use similar cleaning methods as for glass. Repair damaged areas with sealant or tape. 02 Damage Repair and Reinforcement Film Repair Minor tears: Use special film repair tape or plastic film repair tape to patch. Large tears: Cover with new film to reinforce, ensuring the repaired area is smooth and airtight. Glass/Insulated Panel Maintenance If cracks are...

The minimum light transmittance for greenhouse crops should be determined based on the type of covering material and the crop species. Specific standards are as follows: 01 Basic Standards General Minimum Value: Most common crops (such as leafy vegetables) require a light transmittance of 70% or higher in conventional greenhouses to maintain basic growth requirements. Variations in Covering Materials: Plastic Film: New film generally has a light transmittance of 80%-90%, but in practice, due to aging, contamination, and other factors, a minimum light transmittance of 85% or higher must be maintained. Glass: The standard light transmittance requirement is 91.5% or higher. Solar Greenhouse: The light transmittance is typically 70% or higher. 02 Differences in Crop Requirements High-light Crops: Vegetables (such as tomatoes and peppers) and ornamental flowers require a light transmittance of 90% or higher. Medium-light Crops: For some leafy green vegetables or shade-tolerant crops, the light transmittance can be reduced to around 85%. Special Adjustment Scenarios: In areas or seasons with excessive sunlight, light transmittance can be adjusted to 60%-70% using tools such as sunshade nets. 03 Key Influencing Factors Material Properties: Materials with high haze (such as diffused glass) reduce light transmittance. High-transmittance, low-haze covering materials are preferred....

Much of the glass that’s used for residential and commercial applications is tempered safety glass. In short, tempered glass is heat-treated, making it about 4x stronger than regular, annealed glass. By design, when broken, tempered glass disintegrates into small pieces and is much less likely to do harm.  

It’s a common misconception that clear glass is the most transparent, however, this actually is not the case. Although clear glass does not have substantially high iron content, it does have more than low-iron glass. These higher levels produce a greenish tint, gaining prominence as glass thickens.
