Pipeline matatu-layer PE anti-corrosion tekinoroji nyowani muindasitiri yepipeline anticorrosion.Iwo matatu PE anofukidza yakazara Lou akavharira mabhenefiti, ayo ekubatanidza zvivakwa, magetsi ekudzivirira zvivakwa, kudzivirira mvura uye anti-corrosion kuita uye simba remakanika uye kuoma kwakanakisa.Iyo matatu-layer PE anti-corrosion layer inogona kushandiswa mumamiriro akasiyana ezvakatipoteredza, ese ari epasi-akavakirwa pombi, asiwo kune yemugungwa pombi.

Iyo pombi matatu PE anti-corrosion layer chimiro uye zvinhu
Yekutanga layer ye epoxy poda (FBE) 60 ~m;chikamu chechipiri chekunamatira (AD) 170 kusvika 250 m;chechitatu, polyethylene (PE) - 2.5 kusvika 3.0 mm.Izvo zvinhu zvitatu zvakasanganiswa kuita imwe, uye yakanakisa anti-corrosion layer uye inodzivirira layer inoumbwa nesimbi pombi yakasimba.Iyo yechitatu layer FBE shandisa, AD, PE inofanirwa kuve inogadzirisa bvunzo, inofananidza imwe neimwe kuitira kuti ive nechokwadi chekunamira zvivakwa.Inonamira yePE polymer, ichiwedzera humwe huwandu hwezvinowedzera, kemikari inoitika muFBE gelled ine ethylene, iyo yakasimba kubatana.Zvakare, nekuti iyo inonamira uye PE yemhando imwechete yezvinhu mune yakanyungudutswa, mutual fusion, imwechete yakasimba kubatana.Peeling test kwaive kutadza kwakabatana, kureva kuti pombi yesimbi uye yekufukidza yakasvuura chena yese.
