Thaum nws los txog rau kev tiv thaiv corrosion sab nraud rau cov loj- cov kav dej loj, muaj kev pom zoo hauv kev lag luam: Tsis txhob saib lwm yam, tsuas yog saib rau 3PE qauv. Tsis muaj dab tsi mysterious qab qhov kev xaiv no; nws systematically daws ntau yam teeb meem tseem ceeb uas pipelines ntsib nyob rau hauv lub sij hawm ntev.
Nws lub hauv paus yog peb - txheej txheej txheej txheej. Cov txheej sab hauv tshaj plaws yog fusion- khi epoxy hmoov, nws txoj haujlwm tseem ceeb yog ua kom ruaj khov nrog cov yeeb nkab steel nto, ua ib qho kev thaiv. Nrog muaj zog adhesion thiab zoo tiv thaiv cathodic disbondment, cov primer no daws cov teeb meem tseem ceeb ntawm "adhesion" thiab "tiv thaiv" ntawm txheej thiab cov yeeb nkab steel. Qhov tseem ceeb, qhov primer ib leeg tsis txaus. Nws qhov kev tiv thaiv rau kev puas tsuaj yog qhov txwv, thaum cov kav dej tso thiab ua haujlwm hauv thaj teb tau raug cuam tshuam los ntawm sab nraud thiab kev ntxhov siab. Yog li ntawd, qhov nruab nrab copolymer nplaum txheej yog qhov tseem ceeb. Nws ruaj khov rau cov hmoov epoxy sab hauv thiab sab nrauv siab -polyethylene ntom ntom rau hauv ib qho kev sib koom ua ke, kom ntseeg tau tias tag nrho cov txheej txheej txheej yuav tsis delaminate nyob rau hauv qhov kub thiab txias hloov los yog av nyuaj. Qhov no yog qhov tseem ceeb hauv kev lav phib xaub ntawm kev tiv thaiv kev tiv thaiv tsis muaj tev. Raws li rau txheej txheej sab nraud ntawm siab -polyethylene ntom ntom, nws feem ntau tiv taus cov teeb meem ntawm lub cev thiab ib puag ncig. Nws boasts zoo toughness, hnav tsis kam, thiab cuam tshuam tsis kam, zoo tiv thaiv khawb los ntawm gravel thiab av kev ntxhov siab thaum lub sij hawm rov qab; tib lub sijhawm, nws nthuav tawm cov tshuaj lom neeg ruaj khov thiab ua haujlwm rau corrosive media hauv av. Qhov no sib npaug rau kev muab cov raj xa dej kom muaj zog, huab cua- tiv taus "sab nrauv," muab kev tiv thaiv lub cev muaj zog rau cov txheej txheem sab hauv los tiv thaiv ntau dua - corrosion. Yog li, vim li cas 3PE los tiv thaiv-corrosion tau dhau los ua qhov tseem ceeb tsis yog ib qho kev ua tau zoo tshwj xeeb, tab sis vim nws koom ua ke peb qhov tseem ceeb tiv thaiv -corrosion xav tau ntawm "kev ruaj khov," "tag nrho kev sib txuas," thiab "muaj zog thiab tawv txheej txheej" rau hauv ib qho kev tiv thaiv kev ruaj ntseg thiab pov thawj los ntawm kev sib xyaw ua ke ntawm peb cov ntaub ntawv tshawb fawb.
Thaum kawg, rau lub raj xa dej uas yuav muab faus rau hauv av tau ntau xyoo thiab hla txoj hauv kev nyuaj, xaiv 3PE txhais tau tias xaiv ib qho kev daws teeb meem uas tau raug pov thawj los ntawm kev siv sij hawm ntev - thiab tuaj yeem txo cov kev pheej hmoo ntawm kev saib xyuas thiab cov nqi thoob plaws hauv nws lub neej. Nws sib npaug kev ua tau zoo, durability, thiab kev lag luam, uas yog tej zaum lub hauv paus logic tom qab nws xaiv raws li qhov kev xaiv.
