Izindaba Nemicimbi

Zonke izinhlobo zezingxenye zesistimu ehlanganisiwe (izinsimbi, izingxenye zokushisela, nokunye)2. Izingxenye zemishini yensimbi enembile kanye nezingxenye zepulasitiki zobunjiniyela, izingxenye zokunemba kwemishini3. Imikhiqizo yezimoto, yezokwelapha, ye-3C iyayisebenzisa4. Ukuzenzakalela kwezingxenye ezihlukahlukene zokunemba5. Izingxenye zokunemba zepulasitiki kanye ne-stam

1, isisindo esilula, ukuthunyelwa okulula amapayipi e-PVC-u ensimbi kuphela nepayipi elibunjiwe lensimbi engu-1/5, 1/3 kakhonkolo. Ipayipi inesisindo esilingana nosayizi, ubude obufanayo bepayipi yensimbi eyi-nodular cast 1/4, 1/10 kakhonkolo. Ngakho-ke, ukulayisha nokuthulula okulula, kunciphisa izindleko zokuhamba 1/2-1/3. 1, akukho ushevu, akukho okwesibili

1. iphrojekthi yokuhlinzeka ngamanzi emadolobheni2. amanzi asemadolobheni ephrojekthi yokuhambisa amanzi3. ukwakha ipayipi lokuphakela amanzi4. ipayipi lokuphakela amanzi ngepayipi5. amashubhu okunisela ezolimo6. amapayipi amakhemikhali7. indawo8. amashubhu ensimbi ezimayini

I-extrusion yamapayipi idinga ukuba ne-viscosity ephezulu, kuyilapho ukubunjwa komjovo kudinga impahla ene-liquidity ephezulu. Izidingo zokusebenza komkhiqizo zokuhlanganisa amapayipi ziphezulu kakhulu.Epayipini nasezigxivizweni ezihlangene embonini kusetshenziswa ubuchwepheshe obuthuthukisiwe, ngokusebenzisa inoveli esebenzayo i-catalyst ngu-n.

I-1, ukumelana kwamakhemikhali okungekuhle2, ukumelana nokushisa okungekuhle3, ipulasitiki ephezulu yokuminyana kwe4, ingakhiqizwa ngokubola okushisayo kwe-hydrogen chloride
