dej system

Polyethylene (PE) cov kav dej tshiab ib puag ncig yuav maj mam dhau los ua lub hauv paus ntawm cov dej thiab cov kav dej ua lag luam. Cov kav dej pom zoo rau kev nce qib hauv "Tsoomfwv Saib Xyuas Kev Txhim Kho Kev Txhim Kho thiab Daim Ntawv Thov thiab Kev Txwv thiab Kev Tiv Thaiv Kev Siv Tshuab" feem ntau yog polyethylene (PE), polyvinyl chloride (UPVC) (non- lead ntsev stabilizer) kav. Tsis tas li ntawd, Beijing Municipal Economic Commission, Municipal Planning Commission, Municipal Construction Commission thiab Municipal Public Utility Bureau tau sib koom ua ke tshaj tawm cov ntaub ntawv uas pib txij Lub Xya Hli 1, txhua yam tshiab, rov tsim kho thiab nthuav dav hauv nroog cov dej phwj tuaj, cov dej nag kav dej network, dej. muab cov yeeb nkab network thiab cov pa xa hluav taws xob cov yeeb nkab network Cov phiaj xwm, txhawm rau txhawb nqa daim ntawv thov ntawm polyethylene (PE), polyvinyl chloride (UPVC) thiab lwm cov kav dej tiv thaiv ib puag ncig. Peb lub tuam txhab polyethylene (PE) tsev metering dej system - tsev metering ib leeg-pipe multi-channel dej muab system Cov kav dej yog tsim los ntawm thoob ntiaj teb advanced polyethylene yeeb nkab extrusion ntau lawm kab. Lub barrier-hom ntsia hlau thiab IKV yuam-piv extrusion system xyuas kom meej tag nrho melting thiab plasticization ntawm raw cov ntaub ntawv, thiab xyuas kom meej tias cov polyethylene yeeb nkab muaj zoo heev tiv thaiv sai thiab qeeb tawg thaum siv. Lub polyethylene (PE) tsev metering dej system tsim los ntawm lub tuam txhab - tsev metering ib leeg-pipe multi-channel dej mov kav nruj me ntsis siv GB/T13663-2000, thiab kuj hais txog IS04427-1996. Cov ntsuas ntsuas huv ua tau raws li qhov xav tau ntawm GB / T17219. Polyethylene (PE) tsev metering dej system - tsev metering ib leeg-pipe ntau-channel dej system muaj ntau yam tshwj xeeb ntxiv rau qhov zoo ntawm cov kav dej zoo tib yam.
