Selective Etching Coating for greenhouse glass offers the following significant advantages: High Light Transmittance: Etching coating can significantly improve the light transmittance of glass, reaching over 97.5%, and some products can even reach 99.9% (for specific wavelengths such as infrared light). In greenhouse applications, high light transmittance ensures sufficient light for crops, particularly beneficial wavelengths such as blue and violet light, meeting the needs of crop photosynthesis. Precise Optical Performance: Etching coating uses chemical methods to precisely control the film structure, optimizing optical properties for the specific needs of greenhouses. For example, by adjusting the film thickness and structure, it effectively reduces light reflection and controls light scattering, ensuring more uniform light penetration through the glass, achieving full coverage of every corner in the greenhouse and creating a more stable lighting environment for crop growth. High Durability: The film formed by etching coating is integral to the glass, resulting in high stability and mechanical strength far superior to some traditional coating processes. In the high-temperature and high-humidity environment of a greenhouse, the coating remains resistant to fading, maintaining stable optical properties over time and extending the lifespan of the glass. Pollution-resistant and easy to clean: Etching-coated glass can be restored...

Light is the only free natural energy source during crop growth. Under the same growing conditions, more sunlight means a greater harvest. Yuhua’s specially formulated Pear Anti-Reflective Glass for greenhouses utilizes an etching-based anti-reflection process, maintaining a stable light transmittance of over 97.5%. With this etching-based anti-reflection technology, the anti-reflective layer is incorporated into the glass itself, ensuring no loss of light transmittance during use. With increasing global concern about energy issues and environmental impacts, energy conservation and emission reduction have become key goals across all industries. In high-end greenhouse construction and cultivation, Yuhua Pear Anti-Reflective Glass, with its unique properties, is a key material for increasing crop yields while also promoting energy conservation and emission reduction in greenhouse cultivation. 1. Yuhua Pear Anti-Reflective Glass is a specialized greenhouse glass with low light reflectivity. Compared to traditional glass, it allows more light to penetrate while reducing reflection, thereby increasing light transmission and reducing light pollution. 2. Yuhua Pear Anti-Reflective Glass optimizes natural lighting within the greenhouse while maintaining high light transmittance. It distributes more natural light more evenly throughout the greenhouse, reducing the need for artificial lighting equipment and the intensity of its use, thereby lowering energy consumption. 3. Yuhua...

Sticky Tape Cleaning and Storage Guide As a physical control tool, sticky tape’s cleaning and storage directly impact its reusability and effectiveness. The following provides professional advice on cleaning methods, storage conditions, and precautions to ensure the tape maintains its effectiveness during repeated use. I. Cleaning Methods for Sticky Tape 1. Purpose of Cleaning Extends lifespan: Removes surface pests, dust, and plant debris, restoring the adhesive layer’s adhesion. Reduces contamination risk: Prevents residual pests from carrying pathogens or eggs, leading to secondary infection. 2. Cleaning Procedures 3. Recommended Cleaning Frequency Normal use: Clean once every 1-2 months (adjusted based on pest density). After an outbreak: Clean immediately if the daily insect trapping rate is ≥500/m2. Before long-term storage: Store sealed after cleaning to prevent adhesive degradation. II. Storage Methods for Sticky Insect Tape 2. Storage Container Selection Recommended Food-grade plastic sealed boxes (size ≥ 1.5 times the unfolded area of ​​the sticky tape). Aluminum foil vacuum bags (moisture- and oxidation-resistant after vacuuming). Prohibited Cardboard boxes (susceptible to moisture absorption and insect infestation). Transparent plastic bags (light transmission accelerates adhesive aging). 3. Shelf Life Management Shelf life after cleaning: ≤ 6 months (adhesion decreases over time). Labeling: Mark the outside of...

Use Cycle Replace sticky tape every 1-3 months, depending on pest density and the condition of the adhesive layer. If more than 80% of the sticky tape surface is covered by pests or the adhesive layer has lost its stickiness, replace it immediately. Data Monitoring Regularly count the types and numbers of pests on sticky tapes and analyze patterns of pest occurrence. Combined with other monitoring methods (such as insect traps and sex attractants) to develop a comprehensive prevention and control strategy. Coordination with Other Measures Combined with insect nets, insecticidal lamps, biological control methods, and other measures, to form a multi-layered prevention and control system. Avoid using high-powered wind equipment near sticky tapes to prevent pests from escaping or the tape from falling off. IV. Common Problems and Solutions How do I determine if sticky tapes need to be replaced? Determining whether a sticky tape needs replacement requires considering three key criteria: appearance, attractant effectiveness, and environmental factors. Specific criteria and recommended procedures are provided below: I. Core Criteria 1. Physical Condition of the Adhesive Layer Adhesive Layer Coverage: When the surface of a sticky tape is covered with pests, dust, plant debris, and other debris exceeding 80%, the...

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...
