I-purlin yensimbi enamandla enziwe ngama-purlins (insimbi ye-C-section, insimbi ye-Z-section) njengento eyisisekelo.Ngemuva kokucindezela, ukwakhiwa kwemigodi, ukusika nokwenza, i-epoxy resin powder ishisa ngaphambili ekushiseni okuphezulu ukuze ifakwe futhi iguqulwe, bese icutshungulwa ngokuphulukisa nezinye izinqubo.
Izici zomkhiqizo: 1. Isendlalelo se-epoxy resin se-purlin yensimbi efakwe amandla siwukusebenza okuphezulu kwe-epoxy resin coating.Inokulinganisa okuhle kakhulu, ukuhlobisa, umshini, ukumelana nokugqwala okukhulu.Ukuhlola kubonisa ukuthi: i-purlin ku-30% sulfuric acid, 95% sodium hydroxide, 10% ammonium hydroxide, hydrogen peroxide, 35% hydrochloric acid, 20% nitric acid, 30% phosphoric acid, 40% formaldehyde, sodium oxide, dichlorethylene, electrolyte yethusi. Ifakwe amahora angu-120, umkhiqizo awunalo ushintsho olusobala.
Izici zomkhiqizo:
1. Ungqimba lwe-epoxy resin lwe-purlin yensimbi ehlanganiswe ngamandla luyimbobo esebenza kahle kakhulu ye-epoxy resin.Inokulinganisa okuhle kakhulu, ukuhlobisa, umshini, ukumelana nokugqwala okukhulu.Ukuhlola kubonisa ukuthi: i-purlin ku-30% sulfuric acid, 95% sodium hydroxide, 10% ammonium hydroxide, hydrogen peroxide, 35% hydrochloric acid, 20% nitric acid, 30% phosphoric acid, 40% formaldehyde, sodium oxide, dichlorethylene, electrolyte yethusi. Ifakwe amahora angu-120, umkhiqizo awunalo ushintsho olusobala.
2 I-epoxy resin inokumelana okuhle kakhulu kwesimo sezulu.I-epoxy resin layer ihlukanisa ngokuphelele ukuxhumana phakathi kwensimbi nomoya, igwema i-oxidation nokugqwala kwensimbi, yenza ama-purlins abe nokuqina okukhulu futhi agweme ukugcinwa kwangemuva;
3. Ubuchwepheshe obuthuthukisiwe kanye nefomula yesayensi yenza i-purlin ibe nzima futhi ingagugi, ibe nokunamathela okuqinile futhi ingalokothi i-delamination.I-anti-corrosion layer ngeke iqhekeke noma ixebuke ngemva kokugoba;
4. Ukumelana nokushisa okuphezulu nokumelana nokushisa okuphansi.Lapho izinga lokushisa eliphezulu lingama-degree angu-150 futhi izinga lokushisa eliphansi lingama-degrees angu-40, ukugqoka akunakho ukuxebuka, ukuqhuma, ukuqhekeka, ukukhishwa, ukulimaza kanye nezinye izenzakalo.Umjikelezo wokuqandisa izikhathi ezingu-10, akukho shintsho ku-purlin;
5. Ukufakwa kalula.Uxhumo oluboshiwe luyamukelwa, futhi indinganiso kazwelonke engu-11G521-1-2 ingasetshenziselwa ukufakwa.Imininingwane ye-Purlin ingenziwa futhi icutshungulwe ngokuya ngezidingo zobunjiniyela.
Ama-purlin ensimbi afakwe amandla asetshenziswa kabanzi kwezensimbi, usawoti, umanyolo, ukuphrinta nokudaya, imboni yamakhemikhali, izitsha zobumba, i-electroplating, ukuzalanisa, ukuphonsa, i-chlor-alkali, izinsimbi ezingezona ayoni nezinye izimboni.Kusetshenziswa kabanzi ekuxhumaneni kwezimboni ezisezingeni eliphezulu nasezimbonini zempi.
