1. siab hnav tsis kam
Ultra siab raj molecular hnyav mus txog ntau tshaj 2 lab, qhov hnav Performance index yog tsawg, muab nws tsis tshua muaj siab tiv thaiv zawv zawg kev sib txhuam.Hnav tsis kam yog 6.6 npaug siab dua li cov hlau zoo tib yam thiab 27.3 npaug siab dua cov hlau tsis muaj steel.Nws yog 17.9 npaug ntawm phenolic resin, 6 npaug ntawm nylon, 4 npaug ntawm polyethylene, zoo heev txhim kho kev pab cuam lub neej ntawm cov kav dej.
2. kev tiv thaiv siab
Qhov cuam tshuam toughness tus nqi ntawm uHMW-pipeline yog qhov siab tshaj plaws ntawm cov khoom siv engineering uas twb muaj lawm.Ntau cov ntaub ntawv yuav tawg, tawg, tawg los yog ntog kev nyuaj siab nyob rau hauv hnyav los yog rov tshwm sim tshwm sim.Cov khoom no raws li GB1843 tus qauv, lub cantilever beam cuam tshuam kuaj kom ua tiav tsis muaj kev puas tsuaj, tuaj yeem tiv taus sab nraud muaj zog, sab hauv overload, siab hloov pauv.
3. corrosion kuj
Uhmw-pe yog ib hom saturated molecular pawg qauv, yog li nws cov tshuaj ruaj khov yog siab heev, cov khoom muaj peev xwm tiv taus qhov yaig ntawm cov tshuaj muaj zog, ntxiv rau qee cov kua qaub muaj zog ntawm qhov kub thiab txias muaj qhov corrosion me ntsis, hauv lwm cov alkali, acid yog tsis corroded.Nws tuaj yeem siv rau hauv cov concentrated hydrochloric acid nrog concentration tsawg dua 80%.Nws yog qhov ruaj khov heev hauv sulfuric acid nrog concentration tsawg dua 75% thiab nitric acid nrog concentration tsawg dua 20%.
4. zoo rau nws tus kheej lubrication
Vim tias UHMWPE raj muaj cov khoom siv waxy, thiab nws tus kheej lubrication zoo heev.Kev sib txhuam coefficient (196N, 2 teev) tsuas yog 0.219MN / m (GB3960).Nws qhov kev ua haujlwm zawv zawg yog qhov zoo tshaj ntawm cov roj lubricated steel lossis tooj dag.Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav, plua plav, silt thiab ntau qhov chaw, cov khoom ntawm tus kheej qhuav lubrication kev ua tau zoo yog nthuav tawm ntau dua.Tsis tsuas yog tuaj yeem txav tau yooj yim, thiab tiv thaiv cov khoom ua haujlwm cuam tshuam los ntawm kev hnav lossis lim.
5. tshwj xeeb tsis tshua muaj kub kuj
Ultra siab molecular hnyav polyethylene yeeb nkab muaj qhov kub thiab txias tsis kam, thiab nws qhov cuam tshuam tsis kam thiab hnav tsis kam yog qhov hloov pauv ntawm rho tawm 269 degrees Celsius.Nws yog tam sim no tsuas yog engineering yas uas tuaj yeem ua haujlwm ntawm qhov kub thiab txias ze ze rau qhov tsis muaj tseeb.Nyob rau tib lub sijhawm, uHMWPE yeeb nkab muaj qhov dav ntawm qhov ntsuas kub, uas tuaj yeem ua haujlwm hauv qhov kub ntawm -269 ℃ txog 80 ℃ rau lub sijhawm ntev.
6. Nws tsis yooj yim rau scale
Uhmwpe yeeb nkab muaj qhov zoo ntawm qhov tsis-adhesion thiab siab yeeb nkab tiav vim nws qhov sib txhuam coefficient thiab tsis-polarity.Cov ntaub ntawv uas twb muaj lawm feem ntau teev nyob rau hauv nruab nrab nrog PH tus nqi siab tshaj 9, tab sis uHMWPE yeeb nkab tsis scale, uas yog ib qho tseem ceeb heev rau cov thee tshauv paug system nyob rau hauv thermal fais fab nroj tsuag.Hauv cov roj av, av nkos thiab lwm yam kev thauj mus los kuj yog qhov tsim nyog heev.
7. lub neej ntev
Uhmwpe muaj tsawg dua cov noob tsis txaus ntseeg hauv nws cov saw hlau molecular, thiab nws lub zog qaug zog yog ntau dua 500,000 zaug.Nws muaj qhov zoo tshaj plaws kev ntxhov siab tawg tsis kam thiab ib puag ncig kev ntxhov siab tawg ua haujlwm.4000H, ntau tshaj 2 zaug ntawm PE100, faus rau 50 xyoo los yog li ntawd, tseem tuaj yeem tuav tau ntau dua 70% ntawm cov khoom siv kho tshuab.
8. Yooj yim installation
Ultra siab molecular yuag polyethylene (UHMW--PE) yeeb nkab chav tsev qhov ntev yog tsuas yog ib feem yim ntawm cov yeeb nkab steel qhov hnyav, kom thauj khoom thiab tshem tawm, kev thauj mus los, kev teeb tsa yooj yim dua, thiab tuaj yeem txo qhov kev siv zog ntawm cov neeg ua haujlwm, UHMW-PE yeeb nkab muaj zog tiv thaiv kev laus, 50 xyoo tsis yooj yim rau kev laus.Txawm hais tias hauv av erection, lossis faus hauv av tuaj yeem ua tau.Txawm hais tias vuam lossis flange txuas tuaj yeem ntsia tau, muaj kev nyab xeeb, txhim khu kev qha, nrawm thiab yooj yim, tsis muaj corrosion, kev ua haujlwm thiab kev txuag hluav taws xob, tag nrho qhia txog kev siv uHMWPE pipeline "zog txuag, kev tiv thaiv ib puag ncig, kev lag luam thiab kev ua haujlwm" superiority.
9. Lwm yam nta
Ultra siab molecular hnyav polyethylene yeeb nkab thiab lub zog nqus, suab nrov nqus, tiv thaiv zoo li qub, hluav taws xob tiv thaiv muaj peev xwm, tsis nqus dej, lub ntiajteb txawj nqus, yooj yim machining, xim thiab lwm yam tseem ceeb.
