Kweminye imibuzo kunye iimpendulo malunga epoxy glass ifayibha ilaphu laminate, uya kwazi ngakumbi emva kokufunda

Ilaphu le-epoxy glass fiber laminate sisiseko seebhodi zesekethe eziprintiweyo. Izinto eziphathekayo ziyi-fiber yeglasi, kwaye inxalenye ephambili yiSiO2. I-fiber yeglasi ilukwe kwilaphu kwaye igqunywe nge-epoxy resin, yinkqubo enzima kakhulu.

1. Yisebenzise ukuba ube neqondo elithile leplastiki kunye nokuqina njengeqokobhe lesixhobo esithile okanye oomatshini, njengeemoto, iiyachts, njl.

2, i-substrate yebhodi yesiphaluka.

1. Ziziphi iinkcukacha zebhodi yelaphu yeglasi ye-epoxy kwaye yintoni ibhodi ye-epoxy?

Ibhodi yelaphu yeglasi ye-epoxy ityheli, i-epoxy resin, kunye nebhodi ye-epoxy yeglasi yefiber yenziwe ngefiber yeglasi, ehlala iluhlaza ngamanzi. Ukumelana nobushushu bayo kuphezulu kunebhodi yelaphu yeglasi ye-epoxy, kwaye ukugquma kwayo kuzo zonke iinkalo nako kungcono. Kwilaphu leglasi ye-epoxy

2. Uthini umahluko phakathi kwebhodi ye-epoxy resin kunye nebhodi yelaphu yeglasi ye-epoxy?

Ngokwentetho edumileyo, ezi zimbini ziyafana, kodwa ibhodi ye-epoxy resin ishiye izinto zokuqinisa.

Kukho umahluko phakathi kwezi zimbini. Zininzi iintlobo zezixhobo zokuqinisa ibhodi ye-epoxy resin, eyona iqhelekileyo ilaphu leglasi, kunye ne-glass mat, i-fiber yeglasi, i-mica, njl., kwaye zinokusetyenziswa okwahlukileyo.

Ibhodi ye-Epoxy fiberglass ikwabizwa ngokuba yibhodi ye-fiberglass eyomeleziweyo. Ifanelekile kumatshini, umbane kunye nezixhobo ze-elektroniki ezine-insulation ephezulu. Ineempawu eziphezulu zomatshini kunye ne-dielectric, ukumelana nobushushu obuhle kunye nokumelana nokufuma.

Inezi mpawu zilandelayo:

1. Iifomu ezahlukeneyo

Iintlaka ezahlukeneyo, ii-arhente zokunyanga, kunye neenkqubo zokulungisa zingaphantse zilungele iimfuno zezicelo ezahlukeneyo kwifomu, kwaye uluhlu lunokusuka kwi-viscosity ephantsi kakhulu ukuya kwindawo ephezulu yokunyibilika.

2. Unyango olulula

Khetha iintlobo ezahlukeneyo zeearhente zokunyanga, inkqubo ye-epoxy resin iphantse yanyangeka kuluhlu lobushushu obuyi-0℃ 180℃.

I-3, ukunamathela olomeleleyo

Ubukho bepolar hydroxyl kunye ne-ether bond ekhoyo kwitsheyini yemolekyuli ye-epoxy resin iyenza ibe nokuncamathela okuphezulu kwizinto ezahlukeneyo. I-shrinkage ye-epoxy resin iphantsi xa iphilisa, kwaye uxinzelelo lwangaphakathi olwenziwe luncinci, olunceda ekuphuculeni amandla okubambelela.

4, ukushwabana okuphantsi

“Impendulo ye-epoxy resin kunye ne-agent ephilisayo esetyenzisiweyo iqhutywa ngokuphendula ngokuthe ngqo kokudibanisa okanye ukuvuleka kwe-ring-open-polymerization reaction yamaqela e-epoxy kwi-molecule ye-resin, kwaye akukho manzi okanye ezinye iimveliso eziguqukayo ezikhutshwayo. Xa kuthelekiswa neentyantyambo ze-polyester ezingaxutywanga kunye ne-phenolic resins, zibonisa i-shrinkage ephantsi kakhulu (ngaphantsi kwe-2%) ngexesha lokunyanga.

5. Iimpawu zoomatshini

Inkqubo ye-epoxy resin ephilileyo ineempawu ezibalaseleyo zoomatshini.
