Thaum ntxoov ntxoo nets yog ob qho tib si lub teeb thiab cua sov tswj cov ntaub ntawv siv hauv kev ua liaj ua teb thiab kev tswj hwm ib puag ncig sab nraum zoov, lawv pom qhov sib txawv tseem ceeb vim muaj kev hloov pauv ntawm cov ntaub ntawv, cov qauv, thiab kev ua haujlwm. Qhia meej txog qhov sib txawv no pab ua kom tiav kev xaiv meej thiab siv tau zoo hauv cov xwm txheej sib txawv, zam kev ua haujlwm tsis txaus lossis tsis muaj txiaj ntsig zoo.
Los ntawm cov ntaub ntawv muaj pes tsawg leeg, qhov ntxoov ntxoo nets feem ntau muab faib ua ob pawg: polyethylene (PE)-raws li thiab polypropylene (PP)-raws li. PE-based products are primarily made of high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE), with a dense molecular structure, excellent resistance to ultraviolet radiation and damp heat aging, and a service life of 2-4 years, making them suitable for long-term outdoor coverage and siab -load puag ncig. PP-based products have a lower density and a significant cost advantage, but relatively weaker weather resistance, and are mostly used for short-term protection or temporary coverage. Qhov tseem ceeb sib txawv ntawm ob qhov lus dag nyob rau hauv lawv cov kev tiv thaiv rau ib puag ncig yaig, ncaj qha cuam tshuam rau lub neej kev pab cuam thiab txij nkawm zaus.
Nyob rau hauv cov nqe lus ntawm shading kev ua tau zoo thiab spectral yam ntxwv, ntxoov ntxoo nets ntawm cov xim sib txawv thiab weave densities qhia meej qhov sib txawv. Dub ntxoov ntxoo nets muab cov shading siab (txog 80% los yog ntau tshaj) thiab muaj zog nqus cua sov, ua rau lawv haum rau siab - qhov kub thiab txias ib puag ncig yuav tsum tau txias ceev. Silver-cov nets grey sib xyaw ua ke shading thiab reflective zog, xav txog qee qhov hluav taws xob infrared kom txo cov qoob loo scorching thaum txias. Blue nets xaiv xa cov teeb xiav, txhawb nqa photosynthesis thiab morphogenesis hauv cov qoob loo tshwj xeeb. Tsis tas li ntawd, mesh qhov ntom ntom txiav txim siab qhov txuas ntxiv ntawm shading-cov nets muab cov shading zoo li qub tab sis txwv kev sib kis ntawm lub teeb, thaum cov nets sparse khaws cov teeb pom kev zoo dua qub, haum rau lub teeb -kev hlub cov qoob loo. Qhov sib txawv no tseem ceeb sawv cev rau kev tswj xyuas lub teeb zoo thiab muaj nuj nqis, yuav tsum muaj kev sib piv nrog cov qoob loo lub teeb yuav tsum.
Qhov sib txawv ntawm cov khoom siv kho tshuab manifest nyob rau hauv tensile lub zog thiab cua load kuj. Shading nets siv twisted npoo los yog ob -warp, ob -weft weaving tuaj yeem ua tiav tensile lub zog ntawm 300-500 N / 5cm thiab lub zog tsim kua muag ntau tshaj 50 N, muaj peev xwm tiv taus cua ntawm 8 lossis siab dua thiab cov daus daus. Txawm hais tias lub tiaj tiaj zoo tib yam-weave nets pheej yig dua, lawv yuav ua rau muaj kev puas tsuaj los yog ntug fraying hauv huab cua huab cua. Cov kev sib txawv no txiav txim siab txog kev siv ciam teb ntawm cov khoom hauv typhoon-nrhiav thiab snowy cheeb tsam.
Qhov sib txawv hauv daim ntawv thov scenarios stems los ntawm kev ua haujlwm sib txawv. Cov chaw ua liaj ua teb feem ntau siv nruab nrab- mus rau- qhov siab shading netting los tiv thaiv lub caij ntuj sov kub ntxhov; paj yub cog qoob loo yuav tsum tau qis -shading netting kom muaj teeb pom kev zoo; Aquaculture sheds ua qhov tseem ceeb ua pa thiab tiv thaiv corrosion nyob rau hauv siab - av noo ib puag ncig; thiab pej xeem qhov chaw shading qhia txog kev zoo nkauj thiab yooj yim ntawm installation. Qee qhov sib xyaw shading nets, los ntawm ntau- txheej txheej los yog sib piv cov xim sib txawv, ua tiav cov kev hloov pauv ntawm cov shading nyob rau hauv tib cheeb tsam, ua kom muaj kev sib txawv ntawm cov tsoos shading nets.
Qhov sib txawv ntawm cov shading nets yog qhov tseem ceeb ntawm kev hloov kho cov txheej txheem rau kev thov. Cov neeg siv yuav tsum sib txuas cov yam ntxwv ntawm cov khoom siv, kev txwv ib puag ncig, thiab lub hom phiaj kev ua tau zoo los txheeb xyuas qhov zoo thiab qhov tsis zoo ntawm cov khoom sib txawv kom ua tiav qhov kev teeb tsa zoo rau kev txhim kho kev ua liaj ua teb thiab kev tswj cov chaw sab nraum zoov.
