Ipayipi lensimbi elivunguzayo eliqediwe liyakhishwa ngemva kokupholisa amanzi, kodwa ngemva kwakho konke, ngemva kokushisa okuphezulu kokushisa, izinga lokushisa lepayipi lensimbi elivunguzayo lisephezulu impela ngemva kokupholisa amanzi, ngakho-ke amaphuzu alandelayo kufanele aqashelwe ngemva kokukhishwa kwepayipi elivunguzayo. ihlobo :

Eyokuqala: Enqubweni yokukhiqiza ipayipi lensimbi elivunguzayo, i-epoxy powder kanye ne-adhesive kufanele ibe yi-1% enkulu kunokuvamile, ukuze kuzuzwe ubukhulu obudingekayo.

Okwesibili: Ungabeki ezingeni lokushisa eliphezulu ngemva kokuba ipayipi lensimbi elivunguzayo likhishiwe emugqeni.Ukuchayeka kalula kungaholela ekwandiseni isendlalelo se-PE futhi ngaleyo ndlela udonga lwangaphandle lwepayipi lensimbi, elingeke lifinyelele umphumela wokulwa nokugqwala.

Okwesithathu: Ungachayeka emvuleni ngemva kokuba ipayipi lensimbi elivunguzayo likhishiwe emugqeni.Kulula ukubangela ukugeleza kwamanzi endaweni ehlangene yepayipi ngemva kwemvula.

Okwesine: Ngemva kokuba ipayipi lensimbi elivunguzayo lisusiwe emugqeni, kufanele libekwe endaweni eyisicaba, futhi kufanele libekwe phansi.Ningampintshani.Uma uhlobo lwe-extrusion lubekwe okungenani amahora angu-24, ungqimba lwe-PE kufanele lufakwe ngokuphelele odongeni lwangaphandle lwepayipi yensimbi..

Isakhiwo se-3PE anti-corrosion:

Ibanga elijwayelekile ≥ 0.70 ungqimba olulodwa lwe-primer + ungqimba olulodwa lwesendlalelo sangaphakathi + ungqimba olulodwa lwebhande langaphandle

Ibanga eliqinisiwe ≥ 1.40 ungqimba lwe-primer + ungqimba lwangaphakathi (ukugqagqana kungu-50~55% we-tape ububanzi)

Ungqimba olulodwa lwetheyiphu yangaphandle (ukugqagqana kungu-50 ~ 55% we-tape ububanzi)

Ngokuyinhloko isetshenziselwa ukudluliswa kwamafutha kanye negesi yemvelo;indawo engaphandle yamapayipi ensimbi agqitshiwe afana nokuhlinzekwa kwamanzi kanye ne-drainage kanye nokuthuthwa kwegesi ekwakhiweni kwamakhemikhali nasemadolobheni i-anti-corrosion, enezici zokwakha okulula futhi akukho kungcola.I-polyethylene PE anti-corrosion tape yokunamathisela isetshenziswe kabanzi njengento yangaphandle evimbela ukugqwala kumapayipi ensimbi kawoyela negesi kusukela ngawo-1960.Isetshenziswe iminyaka engaphezu kwengu-40.Ngenxa yokusebenza kwayo okuhle kakhulu kwe-anti-corrosion nokusebenza kahle kokwakhiwa, ikwenze kwaba into evimbela ukugqwala kwamapayipi.Uhlelo lunesikhundla esithile.Futhi kusukela polyethylene enamathela ukukhiqizwa tape amabhizinisi ngokuqhubekayo ngcono futhi ngcono polyethylene PE ezihlukahlukene kanye nekhwalithi anti-ukugqwala adhesive tape, ukuze polyethylene PE izicelo anticorrosion Adhesive tape eyandayo.
