2021-06-23

PVC vamzdis pagamintas iš polivinilchlorido dervos ir stabilizatoriaus, tepalų su karšto presavimo ekstruzijos liejimo plastikinių vamzdžių medžiaga, paprastai naudojama kanalizacijai, nuotekoms, chemikalams, šildymo skysčiams ir aušinimo skysčiams transportuoti, maistui, ypač grynam skysčiui, purvui, dujoms, suslėgtam orui. ir vakuuminės sistemos transmisija.

PVC can be divided into soft PVC and hard PVC.  Soft PVC is generally used for floor, ceiling and leather surface, but due to the poor physical properties of plasticizer contained in soft PVC, the scope of use is limited.  Hard PVC does not contain plasticizer, so it is easy to form and has good physical properties.  PVC material production process, to add stabilizer, plasticizer and so on, if all the use of environmental additives, the PVC pipe is also non-toxic and odorless environmental products.  

PVC vamzdžių pranašumai

1 It has good tensile strength and compressive strength, but its flexibility is not as good as other plastic pipes.  

2 fluid resistance is small: PVC-U pipe wall is very smooth, the resistance to fluid is very small, its roughness coefficient is only 0.009, its water delivery capacity can be compared with the same diameter of cast iron pipe 20%, 40% more than the concrete pipe.  

3 atsparumas korozijai, atsparumas vaistams yra geras: PVC-U vamzdis turi puikų atsparumą rūgštims, šarmams, atsparumą korozijai, neveikia drėgmės ir dirvožemio pH, vamzdynų klojimas be antikorozinio apdorojimo.

4 with good water tightness: PVC-U pipe installation, whether the use of adhesive or rubber ring connection, have good water tightness.  

5 įkandimų prevencija: PVC-U vamzdelis nėra mitybos šaltinis, jo nesugraužs graužikai.
