Imuphi upende ongawuwisi ipayipi lensimbi eliwuthayela?

Ubuso bombhobho wensimbi obushelelezi bushelelezi kakhulu, ekusebenziseni isikhathi eside kwe-substrate kuzophinde kwenzeke ukugqwala, ukuze kuqinisekiswe ukusetshenziswa okujwayelekile kwepayipi elinamandla, indlela yokudweba ingavikela kangcono insimbi.Kodwa-ke, kumapayipi ensimbi, upende omningi wokunamathisela othandwe phezu komhlaba awulungile, ifilimu kapende nokunamathela okubushelelezi akulungile, kujwayele ukuvala inkinga, ngakho ipayipi lensimbi elinamuphi upende ongcono?

I-ED1000 Epoxy Primer iyinalethi ekhethekile yobuso be-substrate enamapulangwe enamathela kahle kakhulu kanye nokuvikela okuhle kwamapayipi athathiwe.Izici eziyinhloko ze-primer yilezi:

1. Ifanele i-substrate yama-galvanized, insimbi engagqwali, i-aluminium alloy, ipuleti le-aluminium nezinye izinsimbi ezibushelelezi, ukunamathela okuqinile, ifilimu yokunamathela ngokuqinile;

2, ukwelashwa kwe-substrate surface kulula, akukho sandblasting, akukho ukugaya, ukusetshenziswa kwe-solvent ukususa uwoyela kungakhiwa, konga izindleko zabasebenzi kanye nezinto ezibonakalayo;

3, ifilimu ukumelana nesifutho sikasawoti kunamandla, kuze kufike emahoreni ayi-1000, ukunamathela kuqinile, kunokumelana okuhle kakhulu kwe-anticorrosive nokugqwala;

4. Upende awunazo izinsimbi ezisindayo, i-lead ne-chromium, uvumelana nezindinganiso ze-EU zokukhishwa kwezincibilikisi, futhi ulungele ukuthunyelwa kwamanye amazwe okokunamathela kocezu lokusebenza;

5, ingafaniswa nezinhlobonhlobo zopende wokuqeda, njengopende we-fluorocarbon, upende we-polyurethane, upende we-epoxy, upende we-acrylic, njll.

Ipayipi lensimbi eliphehliwe kufanele lisuswe ngaphambi kokudweba uwoyela ongaphezulu, ukusetshenziswa kwe-solvent ukusula ubuso be-substrate kungasusa ngokuphumelelayo uwoyela wamafutha, ukugwema ukuthinta ukunamathela.Faka i-ED1000 epoxy primer ngesifutho, hlanganisa i-primer kanye ne-ejenti yokwelapha ngesilinganiso esingu-9:1, engeza i-epoxy thinner, ugovuze ngokulinganayo, bese ugcoba ugqinsi lwefilimu olushiwo.Ubukhulu befilimu obunconywayo bungama-70μm.

I-ED1000 epoxy primer inokunamathela okuqinile nokumelana nokugqwala okuhle kakhulu, kodwa ukumelana nesimo sezulu esingesihle, ikakhulukazi uma isetshenziswa ngaphandle, idinga ukufaniswa nejazi langaphezulu elimelana nesimo sezulu.I-topcoat evame ukusetshenziswa, njengopende we-fluorocarbons, i-acrylic polyurethane topcoat kanye ne-acrylic topcoat.Ngemuva kokuthi i-primer isomile, sebenzisa i-topcoat bese ufafaza ubukhulu befilimu obucacisiwe.Ubukhulu befilimu obunconywayo bungama-50-60μm.

Ipayipi eliphehliwe nge-primer kanye nokuqeda ukunamathela, ifilimu yokugqoka inokunamathela okuhle kakhulu, ukumelana nokugqwala, ukumelana nokuhlobisa kanye nesimo sezulu, ezindaweni eziningi zemvelo kungaba isivikelo esihle kakhulu.
