Description
본 발명은 비닐하우스 표면에 씌워지는 차광망에 관한 것으로 수박, 참외와 같은 여름작물을 비닐하우스에서 재배할 때, 차양광의 열기가 비닐하우스에 가해지는 것을 적절히 차단하여 비닐하우스 내부가 과열되지 않도록 하는 차광망을 제공하기 위한 것인데 보다 구체적인 것은, 폴리에틸렌모노필라멘트사 28 데니어를 경사로 하고, 폴리에틸렌테이프사 800∼1000 데니어를 위사로 하며, 폴리에틸렌모노필라멘트사 23 데니어를 보강사로 삽입하여 이루어지는 차광망지를 제조할 때, 검은색테이프사를 사용하지 않고, 폴리에틸렌테이프사를 제조할 때, 은색 2.5중량% 백색안료 0.5%를 유브이안정제 2.5∼4중량%를 혼합하여 은백색의 필름을 제조하고, 은백색필름을 4mm 폭으로 세절하여 만든 테이프를 선택하여 태양광의 반사율과 흡수율을 조정함으로써, 하절기 비닐하우스의 내부온도가 30∼35℃를 유지할 수 있게 만든 것이다.The present invention relates to a shading net that is covered on the surface of a plastic house. When cultivating summer crops such as watermelons and melons in a plastic house, the heat of the sunshade is properly blocked from being applied to the plastic house so that the inside of the plastic house is not overheated. In order to provide a light-shielding net, more specifically, when manufacturing a light-shielding net made by inserting a polyethylene monofilament yarn 28 denier as a warp, a polyethylene tape yarn 800 to 1000 denier as a weft yarn, and a polyethylene monofilament yarn 23 denier as a reinforcing yarn, When producing polyethylene tape yarn without using black tape yarn, a silver-white film was prepared by mixing 2.5 wt% of silver color, 0.5% of white pigment, and 2.5-4 wt% of UV stabilizer, and cut the silver-white film into 4 mm width. By adjusting the reflectance and absorption rate of sunlight by selecting the tape made by making this product, the internal temperature of the plastic house in summer can be maintained at 30~35℃.
종래의 차광망은 폴리에틸렌모노필라멘트사 28 데니어를 경사로 하고, 폴리에틸렌 검은색테이프사 800∼1000데니어를 위사로 하여 경사에 편직한 차광망(3)을 제조하여 비닐하우스(1) 비닐지(2) 표면에 덮어씌우기 때문에 태양광 흡수율이 높고 반사율이 낮아 하절기 비닐하우스의 내부온도가 40℃를 상회하게 되어 수박이나 참외와 같은 여름 작물이 꽃을 피울 수 없게 되므로 결실율이 떨어져 수확이 감소하는 불편이 있었다.The conventional light-shielding net is made of polyethylene monofilament yarn 28 denier as a warp, and polyethylene black tape yarn 800-1000 denier is used as a weft yarn to manufacture a light-shielding
본 발명은 상기 불편을 해소하기 위하여 개발된 것이다.The present invention was developed to solve the above inconvenience.
본 발명은 폴리에틸렌테이프사를 폭 3.5∼5mm, 길이 800∼1000데니어를 형성하되, 폴리에틸렌수지에 은색안료 2.5중량%, 백색안료 0.5중량%, 유브이안정제 2.5∼4.0중량%를 혼합하여 은백색의 폴리에틸렌테이프사로 만들어 위사(32)로 선택하고, 이를 12∼13mm 간격으로 배치한 폴리에틸렌모노필라멘트사 28 데니어로 만든 경사(30) 사이에 지그재그로 삽입하고, 위사(23)와, 나란히 유색폴리에틸렌모노필라멘트사 23데니어로 된 보강사(31)를 삽입하여 차광망을 형성하는 구성이다The present invention forms a polyethylene tape yarn with a width of 3.5 to 5 mm and a length of 800 to 1000 denier, but by mixing 2.5 wt % of a silver pigment, 0.5 wt % of a white pigment, and 2.5 to 4.0 wt % of a UV stabilizer to a polyethylene resin, a silver-white polyethylene tape Selected as a weft yarn (32) made of yarn, and inserted in a zigzag manner between the warp yarns (30) made of 28 denier polyethylene monofilament yarns arranged at intervals of 12 to 13 mm, and colored polyethylene monofilament yarns 23 side by side with the weft yarn (23) It is a configuration in which a
이와 같이 된 본 발명은 은백색의 폴리에틸렌테이프사가 태양광 반사율이 18∼36%되고, 광흡수율이 64∼82%로 되어 비닐하우스 표면에 씌우게 되면, 태양광 흡수율이 낮아지므로 태양광 흡수율이 95∼97% 되는 검은색테이프사를 사용하는 차광망에 비하여 광반사율이 높고 광흡수율은 낮게 되므로, 하절기 비닐하우스 지붕의 열기를 조절하여 비닐하우스의 내부온도를 30∼35℃로 유지하게 되므로 여름작물인 수박이나 참외의 개화를 좋게 하고, 결실율을 높여 수확이 많아지는 이점을 얻게 된다.In the present invention as described above, when the silver-white polyethylene tape yarn has a solar reflectance of 18 to 36% and a light absorptivity of 64 to 82% and is covered on the surface of a plastic house, the solar absorptivity is lowered, so that the solar absorptivity is 95 to Compared to the shading net using 97% black tape, the light reflectivity is high and the light absorption rate is low. It has the advantage of improving the flowering of the melon or melon, and increasing the yield by increasing the yield.
