Description

Petrochemical trade is with preventing grass cloth

Technical Field

The utility model belongs to the petrochemical field, concretely relates to petrochemical trade is with preventing grass cloth.

Background

With the improvement of safety standard and the improvement of labor cost, the problem of weeds in petrochemical fields and the periphery is obvious. The artificial weeding has low efficiency and high cost, and multiple rounds of weeding are needed every year; on one hand, a large amount of medicament residues enter natural water or soil by weeding with the herbicide, the herbicide is required to be sprayed for multiple times every year, different kinds of herbicides are required to be used for different grasses, and the injury to operators is large. There is also a significant risk to grazing livestock. The construction period is long and the cost is high by physical isolation methods such as concrete and the like. The agricultural grass-proof cloth is not flame-retardant, the effective period is 3 years at most, and secondary plastic pollution is also formed.

Chinese utility model patent CN204690258U discloses a sun-proof PP grass cloth, which comprises a grass cloth main body, wherein the grass cloth main body is PP plastic woven cloth, and a plurality of carbon black particles, anti-UV particles and light stabilizing particles are uniformly distributed in the grass cloth main body; the utility model discloses a through using high-quality brand-new PP raw materials in preventing grass cloth main part to add carbon black granule, anti UV granule and light stabilization granule, be used for improving each item performance index who prevents grass cloth main part, prolonged the life who prevents grass cloth main part greatly, make it more have the practical value that is used for outdoor, farmland, sunshine such as orchard directly to shine the condition for a long time.

Chinese patent application CN106835429A discloses a high-strength light-proof grass-proof cloth which is made of warp and weft yarns, the warp and weft density of the grass-proof cloth is 10-14 x 10-14 pieces/inch, and the gram weight of the grass-proof cloth is 90-130 g/m²The warp and weft yarns are flat yarns made of raw materials mixed by polypropylene PP and high-density polyethylene HDPE according to a weight ratio of 99-95: 5-1. The yarns of the grass-prevention cloth can be better linked to achieve the purpose of light tightness, and the warp and weft yarns are flat yarns made of raw materials mixed by polypropylene PP and high-density polyethylene HDPE according to the weight ratio of 99-95:5-1, so that the softness is improved, the weaving of the grass-prevention cloth is facilitated, and meanwhile, the strength of the flat yarns is improved, so that the strength of the grass-prevention cloth is improved, and the grass-prevention cloth has the characteristics of high strength and light tightness, and is uniform in folding and high in strength. The grass prevention cloth has strong air permeability, weak weed removing capability and inhibiting capability, and no flame retardant property, and cannot be applied to the petrochemical industry.

The Chinese invention patent CN105542401B discloses a PET grass-prevention cloth, which comprises a PET raw material, an auxiliary agent and nano silver; the auxiliary agent comprises an antioxidant, a filler, a tackifier, a flexibilizer and a color master batch; the weight ratio of the PET raw material, the antioxidant, the filler, the tackifier, the toughening agent, the color master batch and the nano silver is 88-89:2:3:1:3:3: 0.1; gram weight g/m of base cloth of PET grass-proof cloth²: 82.3-83.1; radial tensile strength N/5 cm: 788.4-812.8; weft tensile strength N/5 cm: 863.5-897.9; tensile strength retention% in 144 hours of light irradiation: 93.1-95.2; the glossiness is 45 degrees and is more than or equal to 125-132 percent; the light transmittance is less than or equal to 4 percent; the oxygen index is 26.6-27.2; the weed removal rate is more than 99 percent. The grass prevention cloth has a good weeding effect, but is still difficult to be applied to the petrochemical industry.

The oil field and chemical industry park often need large tracts of land weeding and prevent the grass, but at present there is not suitable for the oil field and chemical industry park prevent the grass cloth.
