For some questions and answers about epoxy fiber glass cloth laminate, you will know more after reading

Laminate fiber galaas galaas ah laminate waa maaddada aasaasiga ah ee looxyada wareegga daabacan. Maaddadu waa fiber galaas ah, qaybta ugu muhiimsanna waa SiO2. Fiberka dhalada ah waxa lagu dhex daraa maro waxaana lagu dahaadhay resin epoxy, kaas oo ah hab aad u adag.

1. U isticmaal si aad u yeelato heer balaastig ah iyo adayg gaar ah sida qolofka qalabka ama mishiinada qaar, sida baabuurta, doonyaha, iwm.

2, substrate ee guddiga wareegga.

1. Maxay yihiin qeexitaannada looxa muraayadda epoxy iyo waa maxay guddiga epoxy?

Boodhka maro galaas ah ee epoxy waa huruud, maaddaduna waa resin epoxy, iyo looxa fiber galaaska epoxy waxa uu ka samaysan yahay fiber galaas ah, kaas oo guud ahaan cagaar biyo ah. Cadaadiska heerkulku wuu ka sarreeyaa kan looxa muraayadda epoxy, iyo dahaarka dhammaan dhinacyada ayaa sidoo kale ka fiican. On maro galaas epoxy

2. Waa maxay faraqa u dhexeeya looxa xabagta epoxy iyo looxa muraayadda epoxy?

Sida laga soo xigtay odhaah caan ah, labaduba waa isku mid, laakiin guddiga epoxy resin-ka ayaa meesha ka saaray walxaha xoojinta.

Labadaas farqi baa u dhexeeya. Waxaa jira noocyo badan oo qalab xoojin ah oo loogu talagalay guddiga resin epoxy, midka caadiga ah waa maro dhalada ah, iyo sidoo kale gogosha dhalada, fiber galaas, mica, iwm, waxayna leeyihiin isticmaalyo kala duwan.

Boodhka Epoxy fiberglass sidoo kale waxaa loo yaqaannaa looxa fiberglass-ka la xoojiyay. Waxay ku habboon tahay qaybaha makaanikada, korantada iyo elektiroonigga oo leh dabool sare. Waxay leedahay sifooyin farsamo iyo dielectric sare, caabbinta kulaylka wanaagsan iyo caabbinta qoyaanka.

Waxay leedahay astaamaha soo socda:

1. Noocyo kala duwan

Resins kala duwan, wakiilada daaweynta, iyo hababka wax ka beddelka waxay ku dhawaad ​​​​la qabsan karaan shuruudaha codsiyada kala duwan ee foomka, iyo kala duwanaansho waxay noqon kartaa mid aad u hooseeya ilaa heerkul sare oo adag.

2. Daawaynta ku habboon

Dooro noocyo kala duwan oo dawooyin kala duwan ah, nidaamka resin epoxy ku dhawaad ​​waxaa lagu daweyn karaa inta u dhaxaysa heerkulka 0 ℃ 180 ℃.

3, adhesion xoog leh

Jiritaanka hydroxyl polar iyo bond ether ee ku jira silsiladda molecular ee resin epoxy ka dhigaysa in ay yeelato ku dhegganaan sare oo walxaha kala duwan ah. Hoosudhaca resin epoxy waa hooseeyaa marka la daweynayo, iyo walbahaarka gudaha ka dhasha waa mid yar, kaas oo sidoo kale gacan ka geysta hagaajinta xoogga adhesion.

4, yarayn hooseeya

“Dareen-celinta xabagta epoxy-ga iyo wakiilka daaweynta ee la isticmaalo waxaa lagu fuliyaa falcelin toos ah oo dheeraad ah ama falcelinta polymerization giraanta ee kooxaha epoxy-ga ee molecule resin-ka, biyo ama alaab kale oo kacsan lama sii daayo. Marka la barbar dhigo resins polyester-ka aan dheregsanayn iyo xabagta phenolic, waxay muujinayaan hoos u dhac aad u hooseeya (in ka yar 2%) inta lagu jiro daawaynta.

5. Guryaha makaanikada

Nidaamka resin epoxy ee la daweeyay wuxuu leeyahay sifooyin farsamo oo aad u wanaagsan.
