uchwepheshe wepayipi

Iminyaka eyi-15 Yokukhiqiza

Pert Pipe Black Hdpe Lukathayela Amapayipi Inani

Incazelo emfushane:

Ishubhu le-PE-RT, okuyi-tube engamelana nokushisa i-Polyethylene (PERT), yenziwa nge-MDPE ne-octene copolymerization, isifinyezo sesiNgisi esithi “Polyethylene of pipe lokumelana namazinga okushisa aphakeme”, luhlobo lwethubhu yePolyethylene enganqamuki engasetshenziselwa amanzi ashisayo Abanye baqhakambise izici zayo ezinganqamuki, bayibiza ngokuthi "ipayipi le-polyethylene elingamelana nokushisa okuphezulu."


Imininingwane yomkhiqizo

Amathegi womkhiqizo

Umqondo oyisisekelo

Luhlobo lwe-polyethylene esezingeni eliphakathi nendawo ekhiqizwa ukwakheka okukhethekile kwamangqamuzana nenqubo yokuhlanganisa, isebenzisa indlela ye-ethylene ne-octene copolymerization, ngokulawulwa kwenombolo nokusatshalaliswa kochungechunge lohlangothi ukuthola isakhiwo esiyingqayizivele samangqamuzana, ukwenza ngcono ukumelana nokushisa kwe-PE ithubhu, i-PE tube ukushisa ukumelana nokushisa okuphezulu kakhulu kuka-60 ℃ .Ngenxa yobukhona begatsha elifushane le-octene, ama-mac macoleolecule awakwazi ukufakwa ku-crystal sheet, kepha ngamakristalu amaningana, akha ukuxhumana phakathi kwamakristalu, kugcina okuhle Ukuzivumelanisa nezimo, ukuqhuba okuphezulu kokushisa kanye ne-inertia ye-PE tube, futhi ikwenze kube ngcono ukumelana nengcindezi, kungasetshenziswa isikhathi eside ngaphansi kokuhamba ngamanzi angama-60 ℃ ashisayo.Kugcina ukuguquguquka okuhle kwe-PE, inertia, nokumelana okushisa okuphansi (-40 ℃ ), ukumelana nomthelela, ukumelana nengcindezi kungcono, akunabuthi, akunambitheki, akunangcolisi, ukuvikelwa kwemvelo okuluhlaza, kungabuye kusetshenziswe kabusha. i-llation kanye nokugcinwa.

Le ndlela yokuguqula iyefana namashubhu ajwayelekile we-PPR emakethe namuhla.IPipe-RT amapayipi angasetshenziswa kuwo wonke amabanga wensizakalo wamapayipi amanzi ashisayo acaciswe ku-ISO10508!

Izici zezinto zepayipi

1. Isisindo esincane, kulula ukuthutha, ukufakwa nokwakhiwa.

2. Inokuguquguquka okuhle, okwenza ukubekwa kube lula futhi kube nomnotho. Ipayipi elikhiqizwayo linganciphisa ukusetshenziswa kokufakwa kwamapayipi futhi linciphise izindleko zokwakha ngokugoba nokugoba.

3. Lapho ipayipi ligobile, ingcindezi engxenyeni egobile ingakhululeka ngokushesha, futhi ngeke kube khona into "ebuyayo", evumelana nokusebenza kokwakhiwa.

4. Ukulahlekelwa ukungqubuzana kwepayipi kuncane. Umthamo wokuhambisa uketshezi walolu hlobo lwepayipi mkhulu ngo-30% kunowepayipi lensimbi lobubanzi obufanayo.

Izinga lokushisa eliphansi le-brittle crack.Ukuphakama kokushisa okuphansi kwepayipi kunika amandla ukwakhiwa ezimweni ezibandayo zasebusika, futhi ipayipi alidingi ukufudunyezwa lapho ligobile.

6. Ukumelana nokugqwala kwamakhemikhali okuhle, akukho ukugqwala, impilo ende yokusebenza.

7. Ukuzivumelanisa nezimo okuhle kwemvelo.

8. Ngaphansi kokushisa okusebenzayo kwama-70 ℃ kanye nengcindezi ye-0.4MPa, ingasetshenziswa ngokuphepha iminyaka engaphezu kwengu-50.

9. Azikho izithasiselo ezinobuthi ezingezwa kwipayipi ngesikhathi senqubo yokukhiqiza.Ubambo lwangaphakathi olubushelelezi, akukho ukungcola, akukho ukuzalanisa kwamagciwane, okungasetshenziswa ngokuphepha ekuthuthweni kwamanzi okuphuza nakweminye imikhakha.

10. Ukumelana nomthelela kuyizikhathi ezi-5 zepayipi le-PVC-U.

11. Ukushisa okuhle nokucindezela.

12. Kungaba ukuncibilika okushisayo nokuxhuma kwemishini, okuthembekile, akukho ukuvuza.PE-X ingaxhunyaniswa ngemishini kuphela.

13. Imikhiqizo yokuvikela imvelo eluhlaza, ingavuselelwa kabusha.

14. Ukumelana nokushisa okuphezulu okuphezulu, kungasetshenziswa iminyaka engama-50 ngaphansi kwezimo ezifanele zengcindezi;

15. Ukumelana okuhle nesithwathwa nokumelana nomthelela omuhle, efanelekile ekwakhiweni kwasebusika;

16. Ukumelana nokugqwala kwamakhemikhali okuhle, impilo ende yokusebenza;

I-17 engenabuthi, ayinambitheki, ukusebenza kahle kwezempilo;

18. Isisindo esincane, ukuguquguquka okuhle, kungaba ukunikezwa kwamakhoyili;

19. Izinto ezincibilikayo ezishisayo zingaphinde zenziwe kabusha, kube nezinzuzo kwezemvelo;

Ishubhu efudumele

1) Ukumelana namazinga okushisa nokucindezela kwesizukulwane sesibili sepayipi le-PE-RT kusobala ukuthi kungcono kunaleso sepayipi lokuqala, ukuze kuqinisekiswe impilo yenkonzo ende.

2), ukuguquguquka okuhle, okugoba kalula, kufanelekile ekwakhiweni kokushisa.

3) Ngenxa yobuningi bezinto zokusetshenziswa kwamapayipi wesizukulwane sesibili se-PE-RT, ukufudumeza kuxhunywe ngokuphepha futhi kwalungiswa ngokushesha okukhulu.

4) Ukusebenza okuhle kakhulu kwemvelo.
