PVC Knife Coated Tarpaulin Functional Cover

PVC knife coated tarpaulin primarily consists of polyvinyl chloride (PVC) and polyester fibers. During production, PVC coating is evenly applied to the base fabric using knife-coating technology, forming a smooth and durable surface. This process allows precise control over coating thickness and uniformity, thereby influencing the material's final properties. In contrast, other common materials like standard printed canvas or mesh fabric may employ different coating methods, such as hot pressing or impregnation. These methods can sometimes result in uneven coating or poor adhesion. The advantage of the knife-coating process lies in its ability to deliver more consistent surface quality, minimizing the occurrence of bubbles or wrinkles.

The "knife coating process" of PVC knife coated tarpaulin makes the cloth fiber and PVC coating combine closely, forming a high-density, non-porous sealing surface layer, which can effectively block metal shavings, dust, wood chips and other fine particles from entering into the interior of the machinery, avoiding wear and tear of gears, bearings and other precision parts due to accumulation of dust, and prolonging the maintenance cycle of the equipment.So Jinze PVC knife coated tarpaulin exhibits high tensile strength and abrasion resistance in its physical properties. Its surface is usually weather resistant and is able to withstand UV rays, rain and general pollutants, which makes it last longer in outdoor applications than some common materials.
 

PVC knife coated tarpaulin is resistant to tearing and fading, offering extended durability. However, under extreme climatic conditions—such as prolonged exposure to strong winds or high temperatures—the fabric may exhibit slight deformation or color changes. These alterations typically do not compromise its fundamental functionality. Therefore, PVC tarpaulin is exactly suitable for functional covers to protect machines, cars, boats or any other equipment.The PVC coating itself is highly resistant to oil, weak acid and alkali corrosion (e.g. machine coolant, lubricating oil, mild chemical reagents), and will not penetrate the cloth surface in case of liquid spills, and can be cleaned up with a simple wipe, preventing oil from penetrating into the enclosure to contaminate electrical circuits or mechanical parts. At the same time, protecting the operator's clothing from being contaminated. Tear resistance (both longitudinal and transverse directions exceed 500N) and scratch resistance surpass those of ordinary canvas or nylon fabrics, enabling it to withstand minor impacts from tools and work pieces during mechanical operations and prevent easy damage to protective covers.

The working temperature range of high quality PVC knife coated tarpaulin is usually -30℃~70℃, it is not easy to harden and crack under the low temperature environment in winter, and will not soften and deform under the high temperature or heat dissipation area of the equipment in summer, so it is suitable for most of the workshop environments that are not in the extreme working conditions,e.g. machining workshop, assembly workshop.

The antioxidant and ultraviolet ray absorber added in PVC coating can delay the aging and yellowing in long-term use. Meanwhile, the tarp surface does not absorb water and is not breathable, so it will not breed mildew in humid environment which is especially suitable for rainy areas in the south or workshops with high humidity. In the regular industrial use scenario, the service life of PVC knife coated tarpaulin protective functional cover can reach 3~5 years, much higher than the ordinary nylon cloth (1~2 years) or plastic film, reducing the labor and material costs of frequent replacement of the protective cover.

PVC coated tarpaulin is soft and flexible. It can be customized cut according to the complex structure of machinery, such as corners, bumps, transmission parts, through sewing, heat sealing or with Velcro, zipper and other accessories, to achieve "fit protection". At the same time, it is light in weight (about 500~800g/ ㎡), and won't add extra load to the small bracket of the machinery or the moving parts to add extra load. We can customize transparent PVC tarp viewing window. Operators can directly observe the running status inside the machinery without disassembling the protective cover.

The knife scraper protective cover can be designed as "removable", for example it can be fixed by snaps or straps.During daily cleaning, it only needs to be removed for wiping or washing and it can be reused after drying. If there are small damages in some areas, they can be repaired by hot welding with PVC patches, without the need for an overall replacement, thereby reducing maintenance costs.
