Cilmiga safaarada ee safaarada ee 'Epoxy'

Compos-Good-apoxy-ka safaarada ee AWWA C213 Sawirka Jaangooyada ee muuqaalka

Sharraxaadda Gaaban:

Jaakadaha saqafka leh ee isku-darka ah iyo xirmooyinka biyaha ee biniska biyaha birta

Kani waa heerka shaqada ee Guryaha Biyaha Mareykanka (AWWA). Xirmooyinka FBE waxaa inta badan lagu isticmaalaa tuubooyinka biyaha birta ah iyo waxyaabaha lagu rakibo, tusaale ahaan tuubooyinka SSAW, tuubooyinka SSAW, tuubooyinka LSAW Tuuqyo aan kala go 'lahayn, xusullada, ee loo yaqaan' Esbows's, oo ah yareynta iwm.

Xirmooyinka isku-dhafka ah ee isku-darka ah waa hal qaybood oo jaakad heer-ku-jir ah oo budada ah oo, marka kuleylka uu shaqeynayo, soo saar falcelin kiimiko ah oo ku saabsan dusha sare ee birta iyadoo la ilaalinayo waxqabadka dhismaheeda. Laga soo bilaabo 1960, codsigu wuxuu ku ballaariyey cabbirro waaweyn oo tuubooyin ah oo ah jaakad gudaha iyo dibadda ah oo loogu talagalay gaaska, saliida, biyaha iyo arrinta biyaha wasakhda ah.

Calaamadaha wax soo saarka

Guryaha jireed ee qalabka budada ee epoxy

Curadka gaarka ah ee 23 ℃: ugu yaraan 1.2 ugu badnaan 1.8
Falanqaynta ka mid ah: ugu badnaan 2.0
Waqtiga Gel ee 200 ℃: In ka yar 120s

Nadiifinta qaloocsan

Dusha sare ee birta ah waa in lagu nadiifiyaa qarax-qarsoodi ah si waafaqsan SSPC-Sp10 / NACE No. 2 haddii aan si kale u qeexin iibsadaha. Qaabka qarashka qaraxu ama qoto dheer oo qoto dheer ayaa ah 1.5 mil ilaa 4.0 milyan (38 μm ilaa 102 μm) lagu cabiro iyada oo la raacayo ASTM D4417.

Guryaha

Tuubada la nadiifiyey waa in lagu yareeyaa heerkulka wax ka yar 260 ℃, isha kuleylka ma sumoobin dusha sare ee tuubbada.

Dhumuc weyni

Budada dahabka ah waxaa lagu dabaqi doonaa tuubbada la kariyey ee dhumucdii finanka ee labisan ee aan ka yarayn 12 milyan (305μm) oo ku yaal bannaanka ama gudaha. Dhumucdii ugu badnaa waa inuusan ka badnaan doonin 16 milyan oo rasmi ah (406μm) haddii uusan soo saaraha ka soo saaro ama uu cayimay prochaser.

Imtixaanka Waxqabadka Epoxy ee Ikhtiyaariga ah

Iibsaduhu wuxuu cadeyn karaa tijaabooyin dheeri ah si loo dhiso waxqabadka Epoxy. Nidaamyada baaritaanka soo socda, oo dhammaantood lagu sameyn doono fardaha wax soo saarka ee tirooyinka tirooyinka, waa la cayimi karaa:
1. Qaybta Qaybta-Qaybta.
2. Interface Porosity.
3. Falanqaynta Falanqaynta (DSC).
4. Cadaadis joogto ah (lo't).
5. Biyo qoyan.
6. Saamaynta.
7. Imtixaanka Miisaaniyadda Cathoadic.
