Kev nyab xeeb nets yog ib hom khoom siv tiv thaiv tus kheej siv los tiv thaiv kev raug mob thaum lub caij nplooj zeeg. Lawv muaj ntau yam kev siv, feem ntau rau ntau yam kev ua haujlwm siab -qhov siab. Kev puas tsuaj los ntawm qhov siab feem ntau tshwm sim ntawm scaffolding, ru tsev, qhov rais, hauv cov qauv dai, qhov tob tob, thiab qhov tob tob. Qhov hnyav ntawm kev raug mob lub caij nplooj zeeg sib txawv nyob ntawm qhov kev ncua deb ntawm lub caij nplooj zeeg, xws li kev tsis taus me me mus rau kev tuag. Lub hauv paus ntsiab lus tiv thaiv kev ruaj ntseg nets yog raws li nram no: kab rov tav nets ua los thaiv cov neeg poob thiab cov khoom, zam los yog txo kev raug mob los ntawm kev ntog thiab cuam tshuam; ntsug nets tiv thaiv tib neeg los yog khoom los ntawm kev poob. Lub net lub zog yuav tsum tiv taus qhov hnyav thiab qhov cuam tshuam ntawm tus neeg lossis nqa cov cuab yeej poob, nrog rau lub zog tensile ntev thiab kev siv zog.
Kev soj ntsuam zoo ntawm kev nyab xeeb Nets
Cov nets kev nyab xeeb yog cov cuab yeej tiv thaiv tus kheej tshwj xeeb uas cuam tshuam nrog lub teb chaws cov khoom ntiag tug thiab kev nyab xeeb ntawm tus kheej. Lawv cov khoom zoo yuav tsum raug tshuaj xyuas thiab pom zoo los ntawm lub chaw saib xyuas thiab tshuaj xyuas hauv lub tebchaws, thiab daim ntawv tso cai tsim khoom yuav tsum tau txais ua ntej kev tsim khoom tuaj yeem pib. Txhua pawg ntawm cov nets kev nyab xeeb yuav tsum muaj daim ntawv tshuaj xyuas los ntawm lub chaw saib xyuas thiab tshuaj xyuas. Txhua qhov kev nyab xeeb yuav tsum muaj daim ntawv pov thawj ntawm kev ua raws li lub luag haujlwm saib xyuas hauv lub tebchaws thiab daim ntawv pov thawj ntawm kev ua raws li lub tuam txhab kev tshuaj xyuas uas txuas nrog rau hauv ntau qhov chaw. Nyob rau tib lub sijhawm, kos npe yuav tsum tau muab, nrog cov cim mus tas li suav nrog: cov chaw tsim khoom lub npe, hnub tsim khoom, tus lej batch, cov ntaub ntawv, specifications, qhov hnyav, thiab daim ntawv tso cai naj npawb.
Cov nets kev nyab xeeb tau muab faib ua kab rov tav nets (P), ntsug nets (L), thiab kaw -mesh kev nyab xeeb nets (ML). Kev ruaj ntseg nets feem ntau muaj cov hlua khi, hlua khi, hlua hlua, thiab hlua hlua. Kaw -mesh kev nyab xeeb nets muaj xws li lub cev net, loops, ntug hlua, thiab cov hlua khi ntxiv. Lub cev thiab txhua yam khoom ntawm kev ruaj ntseg nets yog cov cim tseem ceeb rau kev txiav txim lawv qhov zoo. Cov no muaj xws li: lub zog tawg ntawm ntug hlua, khi hlua, hlua khi hlua, thiab hlua khi hlua. Kaw -mesh kev nyab xeeb nets feem ntau muaj cov khoom nram qab no: tawg lub zog, elongation ntawm kev so, seam tensile lub zog, lub zog tsim kua muag, kev nkag mus rau hauv lub zog, tuav tus nqi ntawm kev tawg lub zog tom qab kev laus, lub zog ntawm lub voj qhib, thiab cov nplaim hluav taws kub. Ob kab rov tav thiab ntsug nets yuav tsum muaj kev cuam tshuam. Vertical nets tsis tuaj yeem hloov cov nets kab rov tav; kev xaiv ntawm kab rov tav thiab ntsug nets yuav tsum tau txiav txim siab raws li kev tsim kho thiab kev thauj khoom qhov siab. Kab rov tav kev nyab xeeb nets xav tau ntau dua load-cov kabmob muaj peev xwm tshaj li ntsug kev ruaj ntseg nets, siv ntau cov ntaub ntawv, thiab hnyav dua. Feem ntau, kab rov tav kev nyab xeeb nets hnyav tshaj 5.5 kg, thiab ntsug kev ruaj ntseg nets hnyav tshaj 2.5 kg.
Cov nets kev nyab xeeb feem ntau yog siv rau hauv qhib- huab cua ua haujlwm. Yog li ntawd, lawv yuav tsum yog huab cua -resistant. Huab cua- cov ntaub ntawv tiv taus feem ntau suav nrog nylon, vinylon, thiab polyester. Cov ntaub ntawv siv hauv tib lub net yuav tsum zoo ib yam, nrog rau qhov ntub dej - rau - qhuav lub zog piv ntau dua 75%, thiab tag nrho qhov hnyav ntawm txhua lub net yuav tsum tsis pub tshaj 15 kg. Lub sijhawm tom qab nplaim taws thiab kub hnyiab ntawm nplaim taws-cov nets kev nyab xeeb yuav tsum tsis pub tshaj 4 vib nas this.
Kab rov tav kev ruaj ntseg nets yuav tsum muaj tsawg kawg yog 3 m dav, thiab ntsug thiab kaw -mesh kev ruaj ntseg nets yuav tsum muaj tsawg kawg yog 1.2 m dav. Qhov ntev ntawm cov hlua khi yuav tsum yog tsawg kawg yog 0.8 m. Qhov sib nrug ntawm txoj hlua khi yuav tsum tsis pub tshaj 0.75 m. Rau qhov ze -mesh kev nyab xeeb nets, qhov sib nrug ntawm cov hlua khi yuav tsum tsis pub tshaj 0.45 m, thiab qhov kev ncua deb ntawm cov hlua khi yuav tsum tsis txhob me me, feem ntau teev raws li saum toj no 0.3 m. Kev nyab xeeb nets tuaj yeem muab faib ua tes-woven thiab tshuab{13}}woven hom. Mechanical knotting tuaj yeem muab faib ua knotted knotting thiab knotless knotting. Feem ntau, lub zog ntawm knotless net knots yog siab dua li ntawm knotted net knots. Cov pob qij txha thiab cov pob qij txha yuav tsum tau ruaj khov thiab tsis txav mus los kom tsis txhob nce qhov mesh loj thiab qhov ntev tsis sib xws. Cov teeb meem no yuav ua rau muaj kev ntxhov siab, thaum kawg ua rau txoj hlua khi tawg.
