Izinto Ezilungisiwe Eziphumelele Kakhulu: I-Glass Fiber Iqinisiwe I-Phenolic Resin Eshintshiwe (FX-501)

I-Phenolic I-Glass Fiber, phakathi kwama-resin okwenziwa embonini yokuqala, ngokuvamile i-polycondensate eyakhiwe yi-polymerization yama-phenols nama-aldehydes phambi kwe-alkaline catalyst. Izithasiselo ezithile zibe sezingeniswa ukuze zixhumanise ukwakheka kwe-macromolecular, ziguqule zibe yisakhiwo esingancibiliki futhi esingenakunyakaziswa esinezinhlangothi ezintathu ze-macromolecular, ngaleyo ndlela sibe yisimo esijwayelekile. i-thermosetting polymer impahla. Ama-phenolic resins aziswa kakhulu ngenxa yezakhiwo zawo ezivelele, okuhlanganisa ukuhlehla kwelangabi elihle kakhulu, ukuqina kobukhulu, namandla amahle okusebenza. Lezi zimfanelo ziqhubekisele phambili ucwaningo olunzulu kanye nokusetshenziswa kwe-phenolic glass fiber resin materials.

Njengoba umnotho wezimboni uthuthuka ngokushesha, izidingo ezikhulayo zibekwa ekusebenzeni kwe-phenolic I-Glass Fiber Materials. Ngenxa yalokho,amandla aphezulu futhi amelana nokushisa ama-phenolic glass fibers aguquliweathuthukiswa kakhulu futhi asetshenziswa. I-Glass fiber reinforced modified phenolic resin (FX-501)okwamanje ingenye yezinto eziphumelela kakhulu eziguquliwe ze-phenolic glass fiber resin. Iwuhlobo olusha lwezinto eziguquliwe neziqinisiwe ze-phenolic ezidalwe ngokuhlanganisa imicu yengilazi ku-matrix ye-resin yasekuqaleni ngokuxuba.

Izakhiwo Zemishini kanye Nezindima Eziyisisekelo

I-phenolic glass fiber resinivame ukukhethwa njenge-matrix ye izinto ezingagugi, eziqinile, nezicindezelayongenxa yamandla ayo aqinile aqinile, ukumelana ne-solvent, kanye nezakhiwo ezinhle kakhulu zemishini njengokubuyiswa komlilo. I impahla ye-matrixngokuyinhloko isebenza njenge-binder, ehlanganisa zonke izingxenye. Imicu yengilaziasebenza njengamayunithi athwala umthwalo ayinhloko ezintweni ezingagugi, anikeze umthamo wokuthwala umthwalo, futhi ukusebenza kwawo okuphakeme kuthinta ngokuqondile umthelela wokuqinisa ku-matrix.

Iqhaza lempahla ye-matrix ukubopha ngokuqinile ezinye izingxenye zezinto eziqinile, ukuqinisekisa ukuthi imithwalo idluliswa ngokufanayo, isakazwe, futhi yabelwe imicu yengilazi ehlukahlukene. Lokhu kunikeza amandla athile nokuqina kokubalulekile. Imicu evamile, okuhlanganisa imicu yengilazi, imicu ephilayo, I-Fibre yensimbis, kanye nemicu yamaminerali, idlala indima ekulungiseni amandla aqinile wento.

Ukuthwala Umthwalo Kuma-Composites kanye Nomthelela Wokuqukethwe Kwe-Fiber

Ku phenolic glass fiber composite material systems, kokubili imicu kanye ne-matrix resin ithwala umthwalo, nemicu yengilazi esele iyisithwali esiyinhloko. Lapho ama-phenolic glass fiber composite engaphansi kwengcindezi yokugoba noma yokucindezelwa, ukucindezeleka kudluliselwa ngokufanayo kusuka ku-resin ye-matrix kuye emicu yengilazi ngayinye ngokusebenzisa isixhumi esibonakalayo, kuhlakazwa ngempumelelo amandla aphethwe. Le nqubo ithuthukisa izakhiwo zemishini yezinto ezihlanganisiwe. Ngakho-ke, ukwanda okufanele okuqukethwe kwe-fiber yengilazi kungathuthukisa amandla ezinhlanganisela ze-phenolic glass fiber.

Imiphumela yokuhlola ibonisa lokhu okulandelayo:

• I-Phenolic glass fiber composite enokuqukethwe kwe-glass fiber engu-20%.ikhombisa ukusatshalaliswa kwefayibha engalingani, kanti ezinye izindawo zintula ngisho nemicu.
• I-Phenolic glass fiber composite ene-50% yokuqukethwe kwe-fiber yengilazibonisa ukusatshalaliswa kwefayibha efanayo, izindawo zokuphuka okungajwayelekile, futhi azikho izimpawu eziphawulekayo zokukhipha ifayibha eningi. Lokhu kusikisela ukuthi imicu yengilazi ingakwazi ukuthwala umthwalo ngokuhlangene, okuholela ekutheni amandla aphezulu e-flexural.
• Lapho okuqukethwe kwe-fiber yengilazi kungu-70%, okuqukethwe kwe-fiber eyeqile kuholela kokuqukethwe kweresin ye-matrix ephansi. Lokhu kungabangela "i-resin-poor-poor" kwezinye izindawo, kuvimbele ukudluliswa kwengcindezi nokudala ukugxila kwengcindezi yendawo. Ngakho-ke, izakhiwo zemishini eziphelele ze-phenolic glass fiber composite material kuthanda ukuncipha.

Kusukela kulokhu okutholakele, i- Ukwengezwa okuphezulu okuvunyelwe kwe-fiber yengilazi kuma-phenolic glass fiber composite ngu-50%.

Ukuthuthukiswa Kokusebenza kanye Nezici Ezinomthelela

Kusukela kudatha yezinombolo, i-phenolic glass fiber composite equkethe i-50% ye-glass fiberkhombisa cishe kathathu amandla e-flexuralfuthi izikhathi ezine amandla okucindezelauma kuqhathaniswa ne-resin ehlanzekile ye-phenolic. Ukwengeza, ezinye izici ezithonya amandla e-phenolic glass fiber reinforced plastics zihlanganisa ubude bemicu yengilazikanye labo umumo.
