Izinto Eziguquliwe Eziphumelele Kakhulu: I-Glass Fiber Eqinisiwe Eguquliwe E-Phenolic Resin (FX-501)

I-Phenolic I-Glass Fiber, phakathi kwama-resin okwenziwa okuqala asezimbonini, ngokuvamile i-polycondensate eyakhiwe yi-polymerization yama-phenols nama-aldehydes lapho kukhona i-catalyst ye-alkaline. Izithasiselo ezithile zibe sezifakwa ukuze zihlanganise isakhiwo se-macromolecule, zisiguqule sibe isakhiwo se-macromolecule esinezinhlangothi ezintathu esinganyibiliki futhi esingangeni, ngaleyo ndlela sibe yinto evamile izinto ze-polymer zokusetha ukushisaAma-resin e-phenolic ayaziswa kakhulu ngezakhiwo zawo ezivelele, okuhlanganisa ukuqina komlilo okuhle kakhulu, ukuzinza kobukhulu, kanye namandla amahle okusebenza. Lezi zimfanelo ziye zakhuthaza ucwaningo olubanzi kanye nokusetshenziswa kwezinto ze-resin ye-fiber yengilazi ye-phenolic.

Njengoba umnotho wezimboni uthuthuka ngokushesha, izidingo ezikhulayo zibekwa ekusebenzeni kwe-phenolic Izinto ze-Glass Fibers. Ngenxa yalokho,imicu yengilazi ye-phenolic eguquliwe enamandla aphezulu futhi engashisiziyathuthukiswa futhi zisetshenziswa kabanzi. I-resin ye-phenolic eguquliwe eqiniswe ngefayibha yengilazi (FX-501)okwamanje ingenye yezinto zokwakha i-resin ye-fiber yengilazi ye-phenolic eguquliwe ephumelela kakhulu. Luhlobo olusha lwezinto ze-phenolic eziguquliwe neziqinisiwe ezidalwe ngokufaka imicu yengilazi ku-resin matrix yokuqala ngokuxuba.

Izakhiwo Zemishini Nezindima Ezizimele

I-resin ye-fiber yengilazi ye-phenolicivame ukukhethwa njenge-matrix ye izinto ezingagugi, ezithambile, nezicindezelayongenxa yamandla ayo amahle okubamba, ukumelana nesinyibilikisi, kanye nezakhiwo ezinhle kakhulu zemishini njengokuvinjelwa komlilo. izinto ze-matrixngokuyinhloko isebenza njenge-binder, ixhumanisa zonke izingxenye ngokwemvelo. Imicu yengilazizisebenza njengamayunithi ayinhloko athwala imithwalo ezintweni ezingagugi, zinikeza amandla okuthwala imithwalo, futhi ukusebenza kwazo okuphezulu kuthinta ngqo umphumela wokuqinisa ku-matrix.

Indima yezinto ezisetshenziswa ku-matrix ukubopha ngokuqinile ezinye izingxenye zezinto ezithambile, ukuqinisekisa ukuthi imithwalo idluliselwa ngokulinganayo, isatshalaliswe, futhi ibekwe ezintanjeni zeglasi ezahlukahlukene. Lokhu kunikeza amandla athile nokuqina kwezinto. Izindwangu ezivamile, kufaka phakathi imicu yeglasi, imicu yemvelo, I-Fiber Yensimbis, kanye nemicu yamaminerali, kudlala indima ekulungiseni amandla okunamathela kwezinto.

Ukuthwala Umthwalo Ezingxubeni kanye Nomthelela Wokuqukethwe Kwefayibha

Ku- izinhlelo zezinto ezihlanganisiwe ze-fiber yengilazi ye-phenolic, kokubili imicu kanye ne-matrix resin kuthwala umthwalo, lapho imicu yengilazi ihlala iyisithwali somthwalo esiyinhloko. Lapho izinhlanganisela ze-phenolic glass fiber zibhekene nokucindezeleka kokugoba noma kokucindezelwa, ukucindezeleka kudluliselwa ngokufanayo kusuka ku-matrix resin kuya ku-glass fibers ngayinye ngokusebenzisa i-interface, kuhlakaza ngempumelelo amandla athwalwayo. Le nqubo ithuthukisa izakhiwo zemishini zezinto ezihlanganisiwe. Ngakho-ke, ukwanda okufanele Okuqukethwe kwefayibha yengilazi kungathuthukisa amandla ezinhlanganisela zefayibha yengilazi ye-phenolic.

Imiphumela yokuhlola ikhombisa okulandelayo:

• Izinhlanganisela ze-phenolic glass fiber ezinokuqukethwe kwe-glass fiber okungu-20%zikhombisa ukusatshalaliswa kwefayibha okungalingani, kanti ezinye izindawo azinazo ngisho nefayibha.
• Izinhlanganisela ze-fiber yengilazi ye-phenolic enokuqukethwe kwe-fiber yengilazi engu-50%kukhombisa ukusatshalaliswa okufanayo kwefayibha, izindawo ezingajwayelekile zokuphuka, futhi azikho izimpawu ezibalulekile zokukhishwa kwefayibha okubanzi. Lokhu kusikisela ukuthi imicu yengilazi ingathwala umthwalo ndawonye, ​​okuholela amandla aphezulu okuguquguquka.
• Uma okuqukethwe kwefayibha yengilazi kungu-70%, okuqukethwe ngokweqile kwefayibha kuholela kokuqukethwe okuphansi kwe-matrix resin. Lokhu kungabangela izenzakalo "ezingenaso i-resin" kwezinye izindawo, okuphazamisa ukudluliselwa kokucindezeleka nokudala ukugxila kokucindezeleka kwendawo. Ngenxa yalokho, izakhiwo ezijwayelekile zemishini yezinto ezihlanganisiwe zefayibha yengilazi ye-phenolic kuvame ukwehla.

Kusukela kulokhu okutholakele, Ukwengezwa okuphezulu okuvunyelwe kwefayibha yengilazi kuma-composites efayibha yengilazi ye-phenolic kungu-50%.

Ukuthuthukiswa Kokusebenza kanye Nezinto Ezithonyayo

Kusukela kudatha yezinombolo, izinhlanganisela ze-phenolic glass fiber eziqukethe i-50% glass fiberumbukiso cishe amandla okugoba aphindwe kathathufuthi amandla okucindezela aphindwe kaneuma kuqhathaniswa ne-resin emsulwa ye-phenolic. Ngaphezu kwalokho, ezinye izici ezithonya amandla epulasitiki aqiniswe nge-fiber yengilazi ye-phenolic zifaka phakathi ubude bemicu yengilazikanye nabo ukuqondisa.
