Niaj hnub no aquaculture thiab ntses ua liaj ua teb hnyav heev nyob ntawm kev ua tau zoo, sib xws, thiab kev ntseeg tau. Ib qho ntawm cov khoom tseem ceeb tshaj plaws yog qhov kev pub mis tsis siv neeg, qhov twg cov kav dej thauj khoom noj los ntawm cov silos mus rau ntses tawb lossis pas dej.
Cov kav dej ib txwm muaj, xws li PVC, cement, lossis hlau, muaj qhov tsis zoo hauv qhov no:
Kev sib txhuam sab hauv siab xav tau cov twj tso kua mis kom siv zog ntau dua los tsav cov dej ntws. Qhov no tuaj yeem suav txog 30% -50% ntawm tag nrho cov kev siv hluav taws xob hauv kev rov ua dej hauv dej (RAS).
Kev tiv thaiv corrosion, abrasion los ntawm pub, thiab tshuaj tua kab mob, uas tuaj yeem ua rau kev laus, kev loj hlob, kev saib xyuas ntau dua thiab hloov cov nqi, thiab muaj peev xwm ua rau muaj kev cuam tshuam rau cov dej zoo thiab cov ntses noj qab haus huv. Puas muaj cov yeeb nkab uas tso cai rau cov dej ntws zoo dua, ua kom ntev dua, thiab kev siv nyiaj ntau dua los ntawm qhov pib?
Cov lus teb yog High-Density Polyethylene (HDPE) kav.
HDPE kav, tshwj xeeb tshaj yog qib PE80 thiab PE100, raug xaiv rau lawv cov kev tiv thaiv corrosion, lub teeb yuag, thiab lub zog siab, ua rau lawv txoj kev lag luam nyiam xaiv.
Vim li cas cov kav dej HDPE tau siv dav hauv Aquaculture?
Cov kav dej HDPE muaj cov phab ntsa zoo heev, nrog rau Manning roughness coefficient ntawm tsuas yog 0.009, qis dua li cov kav dej cement (0.013) lossis siv cov kav hlau steel (siab dua 0.015).
Smooth sab hauv phab ntsa → Txo cov dej tsis kam: Rau 24/7 recirculating aquaculture systems (RAS), cov twj yuav tsum muaj zog tsawg dua kom ua tau raws li tus nqi ntws, muaj peev xwm txuag tau kaum tawm txhiab nyiaj txhua xyoo hauv hluav taws xob.
Corrosion resistance: Tsis zoo li cov hlau, HDPE tiv taus dej hiav txwv, tshuaj, thiab biofouling.
Lub teeb yuag thiab yoog raws: Ib qho yooj yim rau nruab rau hauv cov tawb ntab lossis cov tshuab ze ze.
Lub zog muaj zog: tuaj yeem tiv taus nthwv dej, cua daj cua dub, thiab tuav kev ntxhov siab.
Lub neej ua haujlwm ntev: PE80 thiab PE100 cov kav dej feem ntau kav ntev li 20-50 xyoo hauv cov dej hauv dej.
Rau cov tshuab pub mis tshwj xeeb, HDPE muab qhov tsim nyog los tiv thaiv kev thauj khoom noj kom zoo dua nyob deb. Txawm li cas los xij, kev hnav thiab kev sib txhuam ntawm qhov chaw tseem tseem muaj kev nyuaj.
Common Challenges of HDPE Pipes for Aquaculture and Fish Farming
1. Sab hauv cov yeeb nkab hnav
Txawm tias me me pub pellets tsim kev puas tsuaj tas li thaum lawv ntws los ntawm cov kav dej ntawm kev kub ceev. Thaum lub sij hawm, qhov no maj mam erodes cov yeeb nkab nto.
2. Kev sib txhuam Build-Up
Kev siv ntev ntev, HDPE qhov chaw yuav plam smoothness, nce kev sib txhuam sab hauv, ua rau: kev siv hluav taws xob ntau dua hauv cov tshuab pub mis, pub pellet breakage txo cov khoom noj zoo thiab cov khoom noj tsis tu ncua thiab muaj peev xwm thaiv tau.
3. Cov xwm txheej Marine
Cov dej ntsev, UV raug, thiab bio-loj hlob ceev cov yeeb nkab degradation, ntxiv kev ntxhov siab.
PE80 vs PE100: Qib twg ua tau zoo dua?
Aquaculture kav yog tsim nyob rau hauv PE80 los yog PE100.
PE80: Lub zog zoo, haum rau nruab nrab-siab tshuab, raug nqi.
Pe100: Ntau dua ntom ntom, zoo dua siab tiv taus, zoo dua kev ua tau zoo ntev.
Ob qib, txawm li cas los xij, ntsib kev sib tw hnav thiab kev sib txhuam yam tsis muaj kev hloov kho saum npoo los yog ntxiv cov khoom ntxiv.
Lub luag hauj lwm ntawm Additives hauv kev txhim kho cov yeeb nkab kev ua tau zoo
Txhawm rau txhim kho lub neej ntev ntawm HDPE aquaculture kav, cov tuam ntxhab feem ntau sib xyaw ua cov khoom siv, roj nplua nyeem, lossis cov khoom ntxiv:
• Txo kev sib txhuam sab hauv → smoother feed flow
• Ua kom abrasion tsis kam → qeeb hnav tus nqi
• Txhim khu kev ua tau zoo → zoo ib yam extrusion
• Txhim kho qhov chaw tiav → txo cov microbial txuas
Txawm li cas los xij,Silicone-based additives tau ua pov thawj tshwj xeeb hauv kev daws cov teeb meem no.
Cov ntaub ntawv thov: SIILIKE Silicone Masterbatch LYSI-404 rau Kev Tiv Thaiv Kev Tiv Thaiv
Ib qho kev daws teeb meem yog Silike Silicone Masterbatch LYSI-404, silicone ua lubricant tsim rau polyolefins xws li PE80 thiab PE100. Nws yog dav siv los ua ib qho additive nyob rau hauv HDPE resin systems los txhim kho kev ua tau zoo thiab nto zoo.
Nrog silicone-raws li Additives, HDPE yeeb nkab cov khoom xws li tsis tshua muaj coefficient ntawm kev sib txhuam (CoF), demolding, thiab dispersion yog ho txhim khu kev qha. Nyob rau tib lub sijhawm, qhov saum npoo ua smoother, uas txhim kho kev tiv thaiv kev sib txhuam, khawb tsis kam, thiab ua kom puas.
Vim li cas Silicone Additive LYSI-404 tuaj yeem sib tw hnav thiab kev sib txhuam?
1) Tsim lub lubricating micro-txheej nyob rau hauv lub polymer matrix
2) Txo cov coefficient ntawm kev sib txhuam
3) Txo qhov kev puas tsuaj los ntawm kev pub pellets
4) Txhim kho extrusion efficiency thiab nto smoothness
