Waterproof PVC Tarpaulin Canvas application scenarios:
1. Industrial protection
Equipment coverage: As a protective PVC Coated Tarpaulin for equipment in open-air cargo yards and mines, the dustproof and scratch-resistant properties can extend the service life of the equipment.
Pipeline wrapping: Used for temporary wrapping of petroleum and chemical pipelines, the acid and alkali resistance can withstand chemical solutions with a pH of 2 to 12.
2. Outdoor construction
Temporary sheds: As temporary shed materials for construction sites and power construction sites, the wind resistance level reaches 10 (EN 13561 standard).
Roof waterproofing: Used for waterproof covering of building roofs and warehouse ceilings, with a light transmittance of ≤5%, which can completely block ultraviolet rays.
3. Logistics and transportation
Truck tarpaulin: As a freight PVC Coated Tarpaulin for trucks and ships, the tear strength is ≥300N/5cm in the warp direction, which can resist transportation impact.
Container covering: Used for the top covering of railway freight containers, the waterproof performance can keep the goods dry.
4. Outdoor camping
Tent floor cloth: As the bottom lining PVC Tarpaulin film of camping tents, the oil-proof performance can reduce 80% of oil penetration and increase cleaning efficiency by 50%.
Awning construction: Used for the construction of outdoor awnings and sunshades, the light-transmitting but non-transparent performance can protect privacy while introducing natural light.
5. Agricultural Application
Crop Covering: As a temporary granary and outdoor cover for various crops, the mildew-proof performance can reduce 90% of mold growth.
Farm Roller Blinds: Roller blinds used in pig farms, cattle farms, and chicken farms, with high strength and strong tension, can withstand a local pressure of 50N/cm².
Waterproof PVC Tarpaulin Canvas Cleaning and Maintenance:
1. Daily Cleaning
Dust Cleaning: Use a soft brush or vacuum cleaner (suction power ≤15kPa) to remove surface dust, and avoid high-pressure water guns that may cause edge degumming.
Stain Treatment:
Oil stains: Local oil stains can be wiped with cotton cloth soaked in isopropyl alcohol (concentration 70%). Large areas of oil stains need to be diluted with a water-based degreaser at a ratio of 1:5, and then cleaned at low speed with a floor scrubber and a red grinding disc.
Stubborn glue stains: Use a professional degreasing agent (containing orange oil extract) to soak for 10 minutes, and then remove with a plastic scraper.
2. Regular maintenance
Waterproof performance test: Use a spray device (pressure 0.2MPa) to test the waterproof performance of the joints every quarter, and the leakage points need to be re-coated with PVC special glue.
Color fastness inspection: Use a colorimeter to test the ΔE value of key areas every year. When ≥5, partial reprinting or replacement is required.
3. Long-term storage
Roll storage: diameter ≥30cm, avoid folding to produce permanent creases, storage environment humidity ≤60%RH, temperature 5℃ to 30℃.
Rot prevention measures: Put rodent repellent in the storage area to prevent rodents from gnawing on the base fabric fibers.
Waterproof PVC Tarpaulin Canvas FAQs
Q1: What is the sun resistance performance of PVC Tarpaulin Canvas Waterproof?
A: Passed the 8-level sun resistance test (ASTM G154 standard), the transmittance retention rate of outdoor use for 3 years is ≥85%, and it is recommended to re-test the color fastness every 2 years.
Q2: Does the material support low-temperature installation?
A: It supports construction in a -30℃ environment, but requires the use of low-temperature special glue (opening time extended to 20 minutes) to avoid adhesive failure due to colloid solidification.
Q3: Can gradient blue printing be achieved?
A: It supports CMYK+ spot color printing, with a gradient transition smoothness of 1440dpi, and a minimum color change of 0.1mm.
Q4: What is the minimum order quantity and delivery cycle for customization?
A: The minimum order quantity is 500 square meters, and the delivery cycle for regular sizes is 7 days. Special-shaped cutting requires an additional 15% processing fee and an extension of 3 days.
Q5: Does the material comply with the EU REACH standard?
A: It has passed the SVHC 224 substance test, the content of phthalates (DEHP) is less than 0.1%, and a RoHS 2.0 certification report can be provided.
