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

Ngokuthuthuka okusheshayo emkhakheni wamapulasitiki aqinisiwe wengilazi,izinto ezisekelwe ku-phenolic resinzisetshenziswe kabanzi kuzo zonke izimboni ezahlukene. Lokhu kungenxa yekhwalithi yazo eyingqayizivele, amandla aphezulu emishini, nokusebenza okuhle kakhulu. Enye yezinto ezibaluleke kakhulu ezimele yii-phenolic glass fiber resin material.

I-phenolic 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 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 yeizinto ezingagugi, eziqinile, nezicindezelayongenxa yamandla ayo aqinile aqinile, ukumelana ne-solvent, kanye nezakhiwo ezinhle kakhulu zemishini njengokubuyiswa komlilo. Iimpahla 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, imicu yensimbi, nemicu yamaminerali, idlala indima ekulungiseni amandla okuqinile wento.

 Ukuthwala Umthwalo Kuma-Composites kanye Nomthelela Wokuqukethwe Kwe-Fiber

In i-phenolic glass fiber composite materializinhlelo, kokubiliimicu 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 okufaneleokuqukethwe 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 ekutheniamandla aphezulu e-flexural.
• Lapho okuqukethwe kwe-fiber yengilazi kungu-70%, okuqukethwe kwe-fiber eyeqile kuholela kokuqukethwe kweresin ye-matrix ephansi. Lokhu kungabangela izenzakalo "ezimpofu nge-resin-poor" kwezinye izindawo, kuvimbele ukudluliswa kwengcindezi nokudala ukugxila kwengcindezi yendawo. Ngakho-ke, izakhiwo zemishini eziphelele ze-phenolic glass fiber composite materialkuthanda 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 compositeequkethe 50% ingilazi fiberkhombisa cishekathathu amandla e-flexuralfuthiizikhathi ezine amandla okucindezelauma kuqhathaniswa ne-resin ehlanzekile ye-phenolic. Ukwengeza, ezinye izici ezithonya amandla e-phenolic glass fiber reinforced plastics zihlanganisaubude bemicu yengilazikanye laboumumo.
