Kuv tau hloov kho cov ntawv nyeem kom zoo dua qub, tus kheej, thiab tsawg dua li daim ntawv qhia kev lag luam. Cov qauv tam sim no sib tov luv luv, punchy kev soj ntsuam nrog ntev dua, cov lus piav qhia ntxaws ntxiv. Kuv kuj tau ntxiv me ntsis ntawm cov tswv yim xav tau - hom kev xav uas tshwm sim ntawm - qhov chaw es tsis yog hauv kev sib tham txog kev lag luam.
Dab tsi tiag hnav tawm lub raj float?
Koj tuaj yeem suav cov buoyancy txhua hnub, tab sis tsis muaj qhov teeb meem yog tias lub ntab nws tus kheej poob sib nrug tom qab ob lub caij. Thiab nyob rau hauv txoj haujlwm no, cov khoom uas tua cov cuab yeej siv feem ntau zoo nkauj: dej, hnub ci, thiab sijhawm. Lo lus nug tiag tiag tsis yog tias lub ntab puas tuaj yeem tswj tau ib qho ntawm lawv- nws puas tuaj yeem tswj tau tag nrho peb ib zaug, ib hnub dhau ib hnub.
Cia peb rhuav tshem ob qhov kev hem thawj tshwj xeeb: corrosion thiab UV degradation. Lawv ua haujlwm sib txawv, tab sis lawv ob leeg ua rau koj them nyiaj yog tias koj tsis quav ntsej lawv.
Corrosion: Tus Slow, Invisible Eater
Nov yog qee yam uas kuv tau kawm txog txoj kev nyuaj: dej tsis tu yog tias koj cov khoom kim heev. Dej ntsev yog txhoj puab heev. Cov dej qab zib nrog cov dej ntws hauv kev lag luam tuaj yeem ua rau tsis zoo. Txawm tias cov dej khib nyiab nqa cov tshuaj uas maj mam noj rau hauv qhov chaw tsis muaj kev tiv thaiv.
Yog tias koj siv steel floats-tshwj xeeb yog yam tsis kho- koj tab tom sau npe rau kev kho mob taub hau. Xeb pib me me, feem ntau nyob rau hauv cov chaw uas koj tsis tuaj yeem pom tau yooj yim thaum lub sijhawm kuaj pom sai. Tom qab ntawd nws kis tau hauv qab txheej. Los ntawm lub sij hawm koj pom nws, cov qauv kev ncaj ncees twb raug cuam tshuam. Koj tuaj yeem siv cov xim tiv thaiv lossis epoxy txheej, tab sis cov no yog kho ib ntus. Lawv xav tau kev rov ua dua tshiab, lawv tau khawb thaum tuav, thiab lawv ntxiv cov nqi zog rau lub neej ntawm qhov project.
Tias yog vim li cas kuv tus kheej lean rau HDPE rau txhua txoj haujlwm uas cuam tshuam nrog dej ntev. Nws tsis yog tias HDPE yog flashy lossis siab -tech. Nws tsuas yog boringly ntseeg tau hauv cov ntsiab lus tshwj xeeb no. Cov khoom tsis xeb. Nws tsis oxidize. Nws zaum nyob rau hauv dej ntsev los yog slurry thiab feem ntau tsis quav ntsej txog chemistry uas yuav rhuav tshem cov hlau nyob rau tib lub sijhawm.
Rau dredging thiab mining ua hauj lwm, qhov twg koj nyob nraum soj ntsuam nrog abrasive slurries nyob rau sab saum toj ntawm noo noo, qhov no yuav tseem ceeb heev. Downtime nyob rau hauv cov cheeb tsam no yog kim heev. Ib qho corrosion- cuam tshuam tsis ua haujlwm tsis yog tsuas yog them nqi rau koj ntab - nws raug nqi koj ib hnub ntawm kev tsim khoom ploj thiab kev txhawb nqa cov neeg ua haujlwm kho. Yog li kev xaiv cov khoom uas tshem tawm qhov kev pheej hmoo ua ntej zoo li kev nkag siab zoo, tsis dhau - engineering.
Kev Tiv Thaiv UV: Hnub ci ua rau puas tsuaj ntau dua li koj xav
Tam sim no, corrosion yog ib yam. Tab sis dab tsi txog qhov uas nyob saum dej? Vim tias cov yeeb nkab ntab tsis nyob hauv dej txhua lub sijhawm. Sab saum toj ib nrab, tshwj xeeb tshaj yog nyob rau hauv cov raj xa dej, tau hammered los ntawm lub hnub ncaj qha rau cov xuab moos txhua hnub.
Kuv tau pom cov yas tsis tu ncua tig nkig tsawg dua ob xyoos hauv qab hnub kub kub. Qhov saum npoo tau chalky. Ces koj pib pom tej tawg me me. Ces cov kab nrib pleb loj tuaj. Thiab mam li nco dheev, ib qho zoo kawg nkaus ntab tawg qhib thaum lub sijhawm ua haujlwm tam sim no. Cov npuas dej hauv dej tau nkag mus, thiab koj poob buoyancy.
UV-stabilized HDPE tswj qhov sib txawv. Cov additives yog sib xyaw rau hauv cov khoom nws tus kheej thaum lub sij hawm tsim khoom- tsis yog tsuas yog txau rau hauv txheej txheej. Qhov ntawd ua rau muaj qhov sib txawv tiag tiag. Vim tias cov coatings hnav tawm. Tab sis ua tau - hauv kev tiv thaiv nyob twj ywm rau tag nrho lub neej ntawm ntab. Koj tuaj yeem khawb qhov saum npoo, thiab cov khoom hauv qab yog tseem resistant.
Puas yog nws tiv thaiv UV tag? Tsis muaj dab tsi. Tab sis lub qhov dej- ua HDPE ntab tuaj yeem tuav tau rau kaum xyoo lossis ntau dua nyob rau hauv tshav ntuj hnyav nrog qhov pom me me heev. Qhov ntawd tsis yog kev lag luam hype-nws yog qhov kuv tau pom hauv kev xa rov qab los ntawm cov haujlwm hauv Southeast Asia thiab Middle East.
Qhov kuv tab tom nrhiav rau hauv Qhov Zoo Tshaj Plaws
Tau ntau xyoo, kuv tau tsim ib hom kev kuaj mob hlwb thaum ntsuas cov yeeb nkab floats. Nws tsis yog hais txog buoyancy ratings xwb.
Ua ntej, kuv xyuas cov khoom siv plhaub. Kev sib hloov- pwm HDPE zoo li muaj cov phab ntsa tuab dua qub thiab zoo dua qhov cuam tshuam zoo dua li tshuab- pwm lwm yam. Qhov thib ob, kuv saib ua npuas ncauj. Kaw-cell polyurethane yog tus qauv kev lag luam rau ib qho laj thawj -txawm tias lub plhaub sab nraud tau punctured, cov npuas yuav tsis nqus dej zoo li qhib - cell foams yuav. Qhov ntawd yog ib qho ua tau - nyob rau hauv redundancy uas kuv nyiam heev.
Thiab qhov thib peb - qhov no yuav ua rau pom tseeb -Kuv nug txog qhov tseeb formulation ntawm UV stabilizers. Tsis yog txhua tus neeg tsim khoom siv tib yam zoo lossis ntau. Ib tus neeg muag khoom zoo yuav pob tshab txog lawv cov pob khoom ntxiv. Yog tias lawv tsis tuaj yeem qhia koj tias muaj dab tsi hauv nws, kuv yuav ceev faj.
Economics ntawm Going Cheap
Muaj ib txwm siab kom txuag nyiaj ua ntej. kuv tau qhov ntawd. Cov peev nyiaj muaj tiag.
Tab sis ntawm no yog kuv coj: ib qho pheej yig ntab uas kav peb xyoos thiab tus nqi float uas kav kaum ob xyoos tsis yog cov khoom sib tw tiag tiag. Qhov pheej yig tus yuam kom koj yuav plaub zaug, them plaub zaug ntawm kev teeb tsa kev ua haujlwm, thiab cuam tshuam nrog plaub qhov kev cuam tshuam. Tus hwm tsuas yog zaum ntawd thiab ua haujlwm.
Kuv tau khiav cov lej ntawm qhov no rau cov dej hiav txwv dredging, thiab tag nrho cov nqi ntawm cov tswv cuab feem ntau nyiam cov ntab zoo dua hauv thawj tsib xyoos. Koj tsis them nyiaj ntxiv rau lub npe -koj tau them rau qhov mob taub hau tsawg dua.
Qhov twg Cov Floats tiag tiag tau siv
Nws tsim nyog hais tias cov no tsis yog cov khoom lag luam niche. Koj yuav pom lawv nyob rau hauv kev tsim kho ntug dej hiav txwv, ntug dej hiav txwv dredging, mining slurry kab, dej diversions, thiab txawm ib ntus dej hloov chaw rau kev ua liaj ua teb. Qee qhov chaw no yog cov dej ntshiab huv. Ib txhia yog corrosive marine zones. Qhov tseeb hais tias ib qho HDPE ntab tsim muaj peev xwm ua tau ob qho tib si hais ntau txog ntau yam khoom siv li cas.
Tab sis versatility tsis txhais hais tias ib tug - loj - haum- tag nrho. Rau cov xwm txheej tsis zoo-hais tias, siab-nthwv dej- lub zog tawm ntawm ntug dej hiav txwv-Kuv tseem xav tshuaj xyuas cov phab ntsa thickness thiab cuam tshuam specs ua tib zoo ua ntej xaj.
Kev xav zaum kawg
Thaum kawg ntawm lub hnub, kev tiv thaiv corrosion thiab UV tiv thaiv tsis yog kev kos lub thawv xwb. Lawv yog qhov txawv ntawm lub raj xa dej uas ua rau koj muaj kev thaj yeeb nyab xeeb thiab ib qho uas ua rau koj hauv xov tooj nrog cov neeg muag khoom.
Kuv tsis xav tias koj yuav tsum overcomplicate qhov kev xaiv. Tsuas nug: Puas yuav ntab no tseem ua nws txoj haujlwm hauv tsib xyoos? Hauv kaum? Yog tias cov lus teb tsis meej yog yog, saib mus ntxiv. Vim hais tias nyob rau hauv ib puag ncig marine, dej tsis yooj yim dua thaum lub sij hawm- nws tsuas yog sim sim txhua yam koj muab tso rau hauv.
