Ipayipi lensimbi elilwa nokugqwala elingu-3pe

Ipayipi lensimbi elilwa nokugqwala eliyi-3pe lifaka phakathiipayipi lensimbi elingenamthungo, ipayipi lensimbi elijikelezayofuthiipayipi lensimbi ye-lsawIsakhiwo esinezingqimba ezintathu se-polyethylene (3PE) anticorrosion coating sisetshenziswa kabanzi embonini yamapayipi kaphethiloli ngenxa yokumelana nokugqwala okuhle, ukungena kwamanzi negesi kanye nezakhiwo zayo zemishini.Lokhu kwelashwa kokulwa nokugqwala kuthuthukisa kakhulu ukumelana nokugqwala kwepayipi lensimbi, elifanele izinhlelo zamapayipi ezifana nokudluliselwa kwamafutha, ukudluliselwa kwegesi, ukuthuthwa kwamanzi kanye nokunikezwa kokushisa.

Isakhiwo sesendlalelo sokuqala sepayipi lensimbi elilwa nokugqwala le-3PE:
Ukugqoka ngempuphu ye-Epoxy (FBE):

Ubukhulu bungaba yi-100-250 microns.

Ihlinzeka ngokunamathela okuhle kakhulu kanye nokumelana nokugqwala kwamakhemikhali, kanye nobuso bepayipi lensimbi obuhlangene eduze.

 

Isendlalelo sesibili: i-binder (Adhesive):

Ubukhulu obungaba ngu-170-250 microns.

Kuyi-copolymer binder exhumanisa i-epoxy powder coating nesendlalelo se-polyethylene.

 

Isendlalelo sesithathu: Isembozo se-Polyethylene (PE):

Ubukhulu bungaba ngu-2.5-3.7 mm.

Ihlinzeka ngokuvikelwa kwemishini kanye nesendlalelo sokuvimbela amanzi ekulimaleni ngokomzimba kanye nokungena komswakama.

Inqubo yokukhiqiza ipayipi lensimbi elilwa nokugqwala le-3PE
1. Ukwelashwa kobuso: ubuso bepayipi lensimbi buqhunyiswa ngesihlabathi noma buqhunyiswa ngokudubula ukuze kususwe ukugqwala, isikhumba esincibilikisiwe kanye nokunye ukungcola futhi kuthuthukiswe ukunamathela kwengubo.

2. Ukushisa ipayipi lensimbi: ipayipi lensimbi lishiswa lifike ezingeni lokushisa elithile (ngokuvamile 180-220 ℃) ​​ukukhuthaza ukuhlanganiswa nokunamathela kwempuphu ye-epoxy.

3. Impuphu ye-epoxy yokumboza: fafaza ngokulinganayo impuphu ye-epoxy ebusweni bepayipi lensimbi efudumele ukuze wakhe ungqimba lokuqala lokumboza.

4. Faka i-binder: Faka i-copolymer binder phezu kwe-epoxy powder coating ukuqinisekisa ukubopha okuqinile nesendlalelo se-polyethylene.

5. Ukwembozwa kwe-polyethylene: Isendlalelo sokugcina se-polyethylene sisetshenziswa phezu kwesendlalelo se-binder ukuze kwakhiwe isakhiwo esiphelele esinezingqimba ezintathu.

6. Ukupholisa nokulungisa: Ipayipi lensimbi elimboziwe liyapholiswa futhi lilungiswe ukuqinisekisa ukuthi izendlalelo ezintathu zokulungisa zihlanganiswe eduze ukuze zakhe ungqimba oluqinile olulwa nokugqwala.

Izici nezinzuzo zepayipi lensimbi elilwa nokugqwala le-3PE

1. ukusebenza okuhle kakhulu kokulwa nokugqwala: isakhiwo sokumboza esinezingqimba ezintathu sinikeza isivikelo esihle kakhulu sokulwa nokugqwala futhi sifanelekela izindawo ezahlukahlukene eziyinkimbinkimbi njengezimo ze-acidic ne-alkaline, izindawo zasolwandle njalonjalo.

2. Izakhiwo ezinhle zemishini: ungqimba lwe-polyethylene lunomthelela omuhle kakhulu kanye nokumelana nokungqubuzana futhi lungamelana nomonakalo wangaphandle ongokwenyama.

3. Ukumelana nokushisa okuphezulu nokuphansi: Isendlalelo sokulwa nokugqwala se-3PE singagcina ukusebenza okuhle kokubili ezindaweni zokushisa eziphakeme neziphansi, futhi akulula ukusiqhekeza nokuwa.

4. isikhathi eside senkonzo: Isikhathi senkonzo yepayipi lensimbi elilwa nokugqwala le-3PE esingafika eminyakeni engama-50 noma ngaphezulu, okunciphisa izindleko zokugcinwa kwepayipi kanye nokushintsha.

5. ukunamathela okuhle kakhulu: ukugqoka kwe-epoxy powder kanye nobuso bepayipi lensimbi futhi phakathi kwesendlalelo se-binder kunokunamathela okuqinile ukuvimbela ukugqoka ukuthi kungaqhekezi.

 
Izinkambu zohlelo lokusebenza

1. Ukuthuthwa kukawoyela negesi: okusetshenziselwa ukuthuthwa kwamapayipi kawoyela negesi yemvelo amabanga amade ukuvimbela ukugqwala nokuvuza.

2. Ipayipi lokuthuthwa kwamanzi: elisetshenziswa ekuhlinzekweni kwamanzi emadolobheni, ekuthuthweni kwamanzi, ekuhlanzweni kwendle nakwezinye izinhlelo zamapayipi amanzi, ukuqinisekisa ukuphepha kwekhwalithi yamanzi.

3. ipayipi lokushisa: elisetshenziselwa ukuthuthwa kwamanzi ashisayo ohlelweni lokushisa oluphakathi ukuvimbela ukugqwala kwepayipi nokulahlekelwa ukushisa.

4. ipayipi lezimboni: elisetshenziswa embonini yamakhemikhali, i-metallurgy, amandla kagesi kanye nezinye izindawo zezimboni zepayipi lenqubo, ukuvikela ipayipi ekugugulekeni kwemidiya ebolile.

5. ubunjiniyela basolwandle: obusetshenziswa emipayipini yasolwandle, ezinkundleni zasolwandle nakwezinye izinsiza zobunjiniyela basolwandle, obumelana nokugqwala kwamanzi olwandle nezinto eziphilayo zasolwandle.
