Cov ntaub ntawv raw ntawm cov yas dej phwj tuaj yog dab tsi?

Yas Drainage phaj, Nws yog ib lub phaj ua los ntawm cov polymer molecular siab nrog kev ua haujlwm ntws dej. Los ntawm kev kho tshwj xeeb, nws tsim cov qauv tsis sib npaug, uas tuaj yeem xa cov dej noo, txo qhov siab hydrostatic ntawm cov txheej tsis muaj dej, thiab ua tiav cov txiaj ntsig tsis muaj dej.

1. Cov ntaub ntawv tseem ceeb ntawm cov yas dej phwj tuaj

1. Polystyrene (HIPS)

Polystyrene yog ib hom thermoplastic uas muaj peev xwm ua tau zoo heev thiab muaj zog heev. Hauv kev tsim cov laug cam yas, polystyrene raug ua tiav rau hauv cov ntawv nrog cov qauv concave-convex, thiab cov kav dej ntws tau tsim los ntawm kev stamping lossis extrusion. Txawm li cas los xij, polystyrene tsis muaj zog hauv huab cua thiab kev tiv thaiv corrosion, thiab tej zaum yuav laus thiab tawg thaum raug rau sab nraum zoov ntev.

2, Polyethylene (HDPE)

Polyethylene yog ib hom thermoplastic uas muaj zog thiab ruaj khov, tiv taus xeb, tiv taus huab cua thiab cuam tshuam zoo heev. Hauv kev tsim cov yas dej ntws, polyethylene tuaj yeem ua tiav rau hauv cov ntawv nrog cov kav dej ntws tas mus li, uas txuas ua ke los ntawm kev vuam thermal lossis kev kho tshuab kom ua tiav cov dej ntws tiav. Polyethylene dej ntws muaj lub neej ua haujlwm ntev thiab ua haujlwm tau zoo, thiab tuaj yeem siv rau hauv cov haujlwm tiv thaiv dej xws li hauv qab nthab thiab ru tsev.

3, Polyvinyl chloride (PVC)

Polyvinyl chloride yog ib hom thermoplastic uas muaj peev xwm ua tau zoo heev thiab muaj zog heev. Piv rau polystyrene thiab polyethylene, PVC muaj kev tiv thaiv hluav taws zoo dua thiab tiv taus tshuaj lom neeg corrosion. Hauv kev tsim cov yas dej ntws, polyvinyl chloride raug ua tiav rau hauv cov ntawv nrog cov qauv concave-convex, thiab cov kav dej ntws tau tsim los ntawm extrusion lossis calendering txheej txheem. PVC dej ntws tsis yog tsuas yog muaj cov khoom ntws zoo heev, tab sis kuj tiv taus acid thiab base corrosion thiab hluav taws kub.

4, Polypropylene (PP)

Polypropylene yog ib hom thermoplastic uas sib dua, muaj zog heev nrog huab cua zoo heev thiab tiv taus corrosion. Hauv kev tsim cov yas ntws dej, polypropylene raug ua tiav rau hauv cov ntawv nrog cov kav dej ntws tas mus li, uas tau sib koom ua ke los ntawm kev vuam thermal lossis kev kho tshuab. Polypropylene ntws dej muaj qhov hnyav sib dua thiab kev ua haujlwm ntws dej zoo, uas tsim nyog rau cov kab ke ntws dej ntawm txoj kev, qhov av thiab lwm yam haujlwm.

2. Qhov cuam tshuam ntawm kev xaiv cov khoom siv raw rau kev ua tau zoo ntawm cov yas dej ntws

Kev xaiv cov khoom siv raw muaj feem cuam tshuam tseem ceeb rau kev ua haujlwm ntawm cov yas dej phwj. Cov yas dej phwj ua los ntawm cov khoom siv raw sib txawv muaj zog, tiv taus corrosion, tiv taus huab cua, tiv taus hluav taws, thiab lwm yam. Yog li ntawd, thaum xaiv cov yas dej phwj, yuav tsum xav txog kom zoo raws li qhov xav tau tshwj xeeb thiab cov xwm txheej geological, thiab yuav tsum xaiv cov khoom siv raw thiab hom dej phwj uas tsim nyog tshaj plaws.

Raws li pom tau los ntawm cov saum toj no, cov khoom siv raw ntawm cov yas dej phwj feem ntau suav nrog polystyrene, polyethylene, polyvinyl chloride thiab polypropylene. Cov dej phwj ua los ntawm cov khoom siv raw sib txawv muaj qhov sib txawv hauv kev ua tau zoo, yog li lawv yuav tsum tau xaiv raws li qhov xav tau tshwj xeeb ntawm kev tsim kho.
