Insect mesh specialist SchermNed has increase the UV stability of its insect mesh . This is a further maturation of the particular worm net filter that the company has been supplying for years . In the filter , mesh with a kly value ( kilo - Langley value ) of 1350 becomes the new banner . This was denote by Carl Stougie and Jack van der Voort of the Westland - base screen facility company , which has specialized in louse mesh since 1990 .
The intensity of ultraviolet light radiation is measured in kly ( kilo Langley ) . Kly is the unit that betoken how much UV radiotherapy zip fall on a square centimeter per year . The higher the kly value , the longer a product , in this case insect netting , is resistant to high UV radiation .
" Especially in countries around the equator , this radiation is high , " Carl knows . " But also in southerly Europe , UV radiation is gamey , and high ultraviolet illumination stability is of great importance . "
This twelvemonth , the fellowship caller is append insect clear with the raw , high UV stability for a nursery grammatical construction project in Saudi Arabia . " If you use mesh there with values common for the Netherlands , up to 600 - 650 , that mesh will be used up after three years due to the high UV radiation sickness . "
UnknownSchermNed supplies insect netting for horticulture in various room . Well - known is harmonica netting , and on the loose bankroll or special flexible web tents can also be supplied through SchermNed , but in addition , they have developed their own insect netting product : the insect nett filter . " In this , we were already working with kly values of up to 1000 , " say SchermNed .
More and more growers are observe the advantage of this solution , where the meshwork stays on the interior of the window when the windowpane is open . " This let growers to grow in the same climatic way as without net as well as continue to create a proficient mood . " This is a singular watching , the work force stress , both from test via TNO and from experiences of " many cultivator . "
SchermNed purchase the latest netting with even higher ultraviolet stability . They do not make their own gauze in Naaldwijk . They do work with a long - standing partner(s ) , some since 1990 . " We point out that few people are still aware of the importance of a high kly value . Only when we then show optic material or send a link with an explanation do masses realize its grandness . "
New standardThe question was how far you could go with the kly value in worm veiling . " We put that question to our maker . They will add sealed additive to the interlocking . There is a upper limit to that , though . young techniques now make it possible , and so does the demand from the market , which was n’t there before . As a solvent , we can now supply this improved gauze . Nobody supply interlock with high values . "
For the project in Saudi Arabia , SchermNed is get an instructional video made in several languages for the supervisor and local people who will add the insect meshing filters with the previous mesh at a bombastic projection in the desert . " We used drones , among other things , to simulate the facility in the greenhouses . Surely locals would rather follow a video of a few minutes than read through 12 page of instruction texts . After all , I prefer to do that myself , " Jack then laughs .
He calculates that the eminent time value means that even with a high ultraviolet light breakage of 220 kilo Langley in Saudi Arabia , the mesh will last for years . " After this period , the get out strength is usually still 50 % of the initial value , or in other words , in practice session , the lifespan can be shorter or longer depending on the situation . In the lawsuit of our SchermNed insect filter , for example , the mesh is mounted within , which also has a more overconfident effect on the lifespan due to sunlight ( and also sandpaper ) . A significant improvement over what was potential until now . "
For harmonica mesh , SchermNed already supply mesh with a kly value of up to 1150 . " That is equivalent to 1000 for mesh in our especial dirt ball mesh filter , which persist on the inside of the window . The now even higher value for the insect mesh filter is alone . It is going to become the unexampled standard with us . "
