Cov ntawv ceeb toom hauv av feem ntau yog ua los ntawm cov khoom siv polymer xws li polyethylene (PE) lossis polyester (PET). Cov ntaub ntawv no muaj cov khoom zoo ntawm lub cev thiab tshuaj lom neeg ruaj khov, ua rau lawv tsim nyog rau kev kos cov kav dej hauv av hauv ntau qhov chaw ib puag ncig.
Nyob rau hauv lub ntiaj teb underground bustling, intricate pipelines ua zoo li lub nroog cov hlab ntsha, muab ib tug nruam hwj chim qhov chaw rau nws ua hauj lwm. Txawm li cas los xij, cov kav dej tob tob no kuj ua rau muaj kev nyab xeeb ntau heev. Txhawm rau kom muaj kev nyab xeeb ntawm kev tsim kho, cov kab ntawv ceeb toom hauv av tau tshwm sim los ua cov cim tseem ceeb hauv kev tsim cov kav dej hauv av. Yog li, dab tsi tiag tiag yog cov lus ceeb toom hauv av ua los ntawm?
Cov ntawv ceeb toom hauv av feem ntau siv cov khoom siv polymer xws li polyethylene (PE) lossis polyester (PET) ua cov khoom siv hauv paus. Kev siv dav ntawm cov ntaub ntawv no feem ntau yog vim lawv cov yam ntxwv zoo:
Lub zog siab: Polyethylene thiab polyester cov ntaub ntawv muaj lub zog tensile thiab tsim kua muag, muaj peev xwm tiv taus qee yam sab nraud yam tsis muaj kev tawg yooj yim, ua kom muaj kev ruaj ntseg ntawm cov ntawv ceeb toom hauv av hauv qhov nyuaj thiab hloov chaw hauv av.
Corrosion Resistance: Cov cheeb tsam hauv av yog qhov nyuaj thiab hloov tau, feem ntau nrog cov khoom corrosive xws li acids, alkalis, thiab noo noo. Polyethylene thiab polyester cov ntaub ntawv muaj kev tiv thaiv corrosion zoo heev, ua rau lawv tiv taus ntev - lub sij hawm yaig los ntawm cov xwm txheej no thiab tswj kom muaj kev ncaj ncees thiab kev txheeb xyuas cov ntaub ntawv ceeb toom faus.
Yooj yim txheeb xyuas: Qhov saum npoo ntawm cov ntawv ceeb toom hauv av feem ntau yog luam tawm nrog cov cim ceeb toom tseem ceeb thiab cov ntaub ntawv xa mus, xws li xim, ntawv, thiab cov qauv. Cov paib no tseem pom tau meej dua rau qhov rov qab ntawm cov khoom siv polyethylene lossis polyester, tso cai rau cov neeg ua haujlwm tsim kho sai thiab raug txheeb xyuas qhov chaw thiab cov khoom ntawm cov kav dej hauv av.
