Steel reinforced thermoplastics composite yeeb nkabmuaj cov yam ntxwv zoo ntawm kev tiv thaiv corrosion, tsis muaj qhov ntsuas, du tsis kam, kev txuag hluav taws xob tsis muaj wax, hnav tsis kam, lub teeb yuag thiab lwm yam yeeb nkab yas, thiab nws cov qauv tshwj xeeb kuj tsim cov yam ntxwv hauv qab no:
(1) Zoo creep tsis kam thiab siab ua haujlwm siab lub zog
Vim hais tias cov yas yuav nkag mus rau hauv chav tsev kub thiab nyob rau hauv kev ntxhov siab, thiab nkig tawg yuav tshwm sim nyob rau hauv lub sij hawm ntev kev ntxhov siab, kev cia siab thiab kev coj tus kheej muaj peev xwm ntawm cov kav dej ntshiab yog tsawg heev (feem ntau nyob rau hauv 1.0Mpa).Lub zog txhua yam ntawm cov hlau yog kwv yees li 10 npaug ntawm cov thermoplastics, thiab nws ruaj khov heev thiab tsis nkag mus rau hauv qhov kub ntawm cov yas.Thaum lub mesh steel hlau thav duab yog ua ke nrog cov yas, qhov nkag ntawm cov yas tuaj yeem tswj tau zoo thiab lub zog ntev ntawm cov yas tuaj yeem txhim kho zoo heev.Yog li ntawd, qhov tso cai kev ntxhov siab ntawm polyethylene puas yeeb nkab nrog hlau mesh skeleton yog ob zaug siab dua li ntawm cov yeeb nkab yas.
(2) Zoo kub tsis kam
Lub zog ntawm cov raj yas feem ntau txo qis nrog qhov nce ntawm qhov kub thiab txias hauv nws qhov kev siv qhov kub thiab txias, thiab lub zog ntawm cov tubing yas txo qis dua 10% nrog rau qhov kub thiab txias los ntawm 10 ℃.Vim hais tias lub zog ntawm hlau mesh pob txha pob txha polyethylene puas yeeb nkab txog 2/3 yog yug los ntawm cov hlau mesh skeleton, yog li nws lub zog nrog kev nce ntawm kev siv kub thiab qis dua txhua yam ntawm cov yeeb nkab yas ntshiab.Cov txiaj ntsig kev sim qhia tau hais tias lub zog ntawm cov hlau hlau mesh pob txha pob txha polyethylene cov yeeb nkab sib xyaw txo qis dua 5% nrog nce ntawm 10 ℃.
(3) Rigidity, zoo cuam tshuam tsis kam, zoo seem stability, thiab nruab nrab yooj, nruj thiab mos sib npaug
Lub elastic modulus ntawm steel feem ntau yog hais txog 200 npaug ntawm high-density polyethylene.Lub rigidity, cuam tshuam tsis kam thiab dimension stability ntawm polyethylene composite yeeb nkab nrog hlau mesh skeleton yog zoo dua li lwm yam ntshiab yas yeeb nkab vim muaj zog cov nyhuv ntawm hlau mesh skeleton.Nyob rau tib lub sij hawm, vim hais tias lub mesh steel skeleton nws tus kheej yog ib tug saj zawg zog qauv, cov yeeb nkab composite kuj muaj ib co yooj nyob rau hauv cov kev taw qhia axial.Yog li ntawd, cov yeeb nkab muaj cov yam ntxwv ntawm kev sib xyaw ua ke thiab hloov tau yooj yim, hauv kev thauj khoom thiab kev thauj mus los, kev thauj mus los, kev hloov pauv tau yooj yim thiab kev cia siab rau kev ua haujlwm zoo heev.Kev teeb tsa hauv av tuaj yeem txuag tus naj npawb ntawm kev txhawb nqa, tus nqi qis;Kev teeb tsa hauv av tuaj yeem tiv taus qhov cuam tshuam tam sim ntawd los ntawm kev tawg, slippage thiab tsheb.Cov yeeb nkab me me tuaj yeem khoov tau zoo, nrog cov txheej txheem nyem los yog nab layout, txuag cov yeeb nkab fittings.
(4) Me me thermal expansion coefficient
Vim cov yas yeeb nkab hlau expansion coefficient ntawm 10.6 ~ 12.2 × 10-6 (1 / ℃), ntshiab yas yeeb nkab hlau expansion coefficient ntawm 170 × 10-6 (1 / ℃), hlau mesh skeleton polyethylene puas yeeb nkab nyob rau hauv lub mesh steel. Cov pob txha pob txha, cov thermal expansion ntawm cov yeeb nkab sib txuas tau zoo heev, qis dua txhua yam ntawm cov yeeb nkab uas feem ntau siv, los ntawm kev xeem, Kev nthuav dav coefficient ntawm hlau mesh pob txha pob txha polyethylene puas yeeb nkab yog 35.4 ~ 35.9 × 10-6 (1 / ℃) , uas tsuas yog 3 ~ 3.4 npaug ntawm cov pa roj carbon steel yeeb nkab.Cov txiaj ntsig kev sim qhia tau hais tias cov cuab yeej siv hluav taws xob feem ntau tsis xav tau rau kev teeb tsa faus, thiab cov yeeb nkab tuaj yeem nqus tau (los yog tso tawm) los ntawm kev sib tsoo, yog li txo tus nqi installation.
(5) Kev tawg nrawm yuav tsis tshwm sim
Pure yas yeeb nkab, tshwj xeeb tshaj yog txoj kab uas hla loj ntshiab yas yeeb nkab ntawm qhov kub thiab txias nyob rau hauv qhov kev txiav txim ntawm persistent circumaxial kev nyuaj siab, yooj yim rau tsim sai cracking los ntawm lub zos tsis xws luag, kev nyuaj siab concentration (instantaneous pua pua ntawm meters rau kilometers saum toj no), yog li tam sim no, lub thoob ntiaj teb ceev ceev. tawg tsis kam ntawm cov yeeb nkab yas muab tso rau hauv siab xav tau, thiab cov pa roj carbon tsawg tsis muaj teeb meem tawg tawg, Lub hav zoov ntawm cov hlau mesh tiv thaiv cov deformation thiab kev ntxhov siab ntawm cov yas los ntawm kev ncav cuag qhov tseem ceeb ntawm kev tawg sai.Yog li kev hais lus theoretically, tsis muaj kev tawg sai ntawm cov hlau mesh ncej polyethylene puas yeeb nkab.
6) Cov khoom sib xyaw ntawm cov hlau thiab cov ntaub ntawv yas yog qhov sib xws thiab txhim khu kev qha
Tam sim no, steel-yas composite yeeb nkab nyob rau hauv kev ua lag luam vim hais tias qhov sib xyaw nto ntawm cov hlau thiab yas yog ib qho kev sib txuas tsis tu ncua, kev siv mus sij hawm ntev nyob rau hauv qhov kev txiav txim ntawm kev sib hloov kev ntxhov siab yog ib qho yooj yim rau delamination, uas ua rau kev sib koom ua ke, lub hauv paus caj dab shrinkage, thaiv thiab tsis ua haujlwm.Piv nrog cov hlau mesh pob txha pob txha polyethylene cov yeeb nkab yog cov qauv mesh los ntawm cov nplaum tshwj xeeb kub yaj nplaum (hloov HDPE) kom cov yas thiab hlau mesh sib xyaw ua ke thiab sib xyaw ua ke.Kev sib nrig sib khi quab yuam ntawm ob cov ntaub ntawv yog loj thiab sib xws, thiab cov kev ntxhov siab concentration yog me me.
7) Ob-sided anticorrosion
Cov hlau hlau mesh pob txha pob txha yog sib xyaw hauv cov yas los ntawm cov txheej txheem kub kub tshwj xeeb.Sab hauv thiab sab nrauv ntawm cov yeeb nkab muaj tib yam kev ua haujlwm tiv thaiv corrosion, hnav-tiv taus, du sab hauv phab ntsa, me me kis tau tus mob, tsis muaj scaling, tsis muaj wax, pom tseeb zog-txuag nyhuv, uas yog ntau yig thiab yooj yim rau faus tsheb thauj mus los thiab corrosive ib puag ncig. tej yam kev mob.
(8) Tus kheej taug qab zoo
Vim hais tias ntawm lub neej ntawm cov hlau mesh skeleton, lub faus hlau mesh skeleton polyethylene composite yeeb nkab yuav tsum tau nyob rau hauv lub niaj zaus magnetic nrhiav kom tau txoj kev, kom tsis txhob muaj kev puas tsuaj los ntawm lwm yam excavation tej yaam num.Thiab qhov kev puas tsuaj no yog cov yeeb nkab yas ntshiab thiab lwm cov yeeb nkab uas tsis yog xim hlau los tsim kev puas tsuaj ntau tshaj plaws.
(9) Yooj yim thiab hloov tau yooj yim ntawm cov khoom tsim thiab kev ua haujlwm
Cov qauv thiab kev ua tau zoo ntawm cov khoom tuaj yeem hloov kho los ntawm kev hloov txoj kab uas hla ntawm cov xaim, qhov sib nrug ntawm lub vas, lub thickness ntawm cov yas txheej, cov yas thiab hom, kom ua tau raws li qhov yuav tsum tau muaj ntawm qhov sib txawv ntawm lub siab, kub thiab corrosion. tsis kam.
(10) Tshwj xeeb hluav taws xob fusion sib koom ua ke, ntau yam, installation yog ceev heev thiab txhim khu kev qha
Kev sib txuas ntawm steel hlau mesh ncej polyethylene puas yeeb nkab txais electrothermic kev twb kev txuas thiab flange kev twb kev txuas.Electrothermic kev twb kev txuas yog ntxig cov yeeb nkab sib xyaw rau hauv cov yeeb nkab electrothermic, thiab electrify cov hluav taws xob cua sov xaim kos rau sab hauv ntawm cov yeeb nkab haum kom sov nws.Ua ntej, sab hauv ntawm cov yeeb nkab haum yog melted los tsim yaj, thiab cov yaj nthuav dav thiab ua rau qhov sib txawv ntawm cov yeeb nkab haum kom txog rau thaum cov yeeb nkab sab nraud kuj ua rau yaj, thiab ob qho tib si yaj ua ke nrog ib leeg.Tom qab txias thiab sib sau, cov yeeb nkab thiab cov yeeb nkab haum yog sib txuas nrog tag nrho.
