Ngophuhliso olukhawulezayo kwicandelo lobunjineli beglasi yefiber eqinisiweyo yeeplastiki,izinto ezisekelwe kwi-phenolic resinzisetyenziswe ngokubanzi kumashishini ahlukeneyo. Oku kungenxa yomgangatho wabo owahlukileyo, amandla omatshini aphezulu, kunye nokusebenza okugqwesileyo. Enye yezona zinto zibalulekileyo zabamelii-phenolic glass fiber resin material.

I-Phenolic glass fiber, phakathi kwezinto zokuqala ezenziweyo ze-resin zokwenziwa, ngokuqhelekileyo i-polycondensate eyenziwa yi-polymerization yeephenols kunye ne-aldehydes phambi kwe-alkaline catalyst. Ezinye izongezo ziye zaziswa kwikhonkco elinqamlezayo kwisakhiwo se-macromolecular, ukusiguqula sibe yinto engenakunyibilika kunye ne-infusible ye-three-dimensional macromolecular structure, ngaloo ndlela ibe yinto eqhelekileyo.izixhobo zepolymer thermosetting. I-Phenolic resins zixabiswa kakhulu ngenxa yeempawu zazo ezibalaseleyo, kubandakanya ukubuyiswa komlilo okugqwesileyo, ukuzinza komda, kunye namandla afanelekileyo oomatshini. Ezi mpawu ziye zaqhubela phambili uphando olubanzi kunye nokusetyenziswa kwe-phenolic glass fiber resin materials.

Njengoko uqoqosho lwemizi-mveliso luqhubela phambili ngokukhawuleza, iimfuno ezikhulayo zibekwe ekusebenzeni kwezinto ze-phenolic glass fiber. Ngenxa yoko,Amandla aphezulu kunye nobushushu obunganyangekiyo kwimicu yeglasi ye-phenolicziphuhliswa kakhulu kwaye zisetyenziswa.Ifayibha yeglasi eyomeleziweyo ephuculweyo ye-phenolic resin (FX-501)okwangoku sesinye sezona zixhobo ziphumeleleyo ezilungisiweyo ze-phenolic glass fiber resin. Luhlobo olutsha lwezinto eziguquliweyo kunye nezomeleziweyo zephenolic ezenziwe ngokubandakanya iifiber zeglasi kwi-matrix ye-resin yasekuqaleni ngokuxuba.

 IiPropati zoomatshini kunye neendima ezisisiseko

Phenolic glass fiber resinihlala ikhethwa njenge matrix yeukunxiba-resistant, tensile, kunye nezixhobo ezicinezelayongenxa yokuqina kwayo okuhle, ukuxhathisa kwenyibiliki, kunye neempawu ezigqwesileyo zoomatshini ezifana nokubuyiswa komlilo. Iizinto zematrixngokuyintloko isebenza njengesibophelelo, esidibanisa zonke iinxalenye.Imicu yeglasizisebenza njengezona yunithi ziphambili zokuthwala imithwalo kwizinto ezinxitywayo, ukubonelela umthamo wokuthwala, kunye nokusebenza kwabo okuphezulu kuchaphazela ngokuthe ngqo umphumo wokuqinisa kwi-matrix.

Indima yemathiriyeli ye-matrix kukubopha ngokuqinileyo amanye amacandelo ezinto eziqinileyo, ukuqinisekisa ukuba imithwalo idluliswa ngokufanayo, isasazwe, kwaye yabelwa kwiintsinga zeglasi ezahlukeneyo. Oku kunika amandla athile kunye nokuqina kwizinto eziphathekayo. Iifayili eziqhelekileyo, ezibandakanya iifayili zeglasi, iifayili ze-organic, iifayili zetsimbi, kunye ne-mineral fibers, zidlala indima ekulungiseni amandla obunzima bezinto eziphathekayo.

 Ukuthwala komthwalo kwiiComposites kunye neMpembelelo yoMxholo weFayibha

In i-phenolic glass fiber composite materialiinkqubo, zombiniiifibers kunye ne-matrix resin zithwala umthwalo, kunye nemicu yeglasi eshiyekileyo ingumthwali womthwalo wokuqala. Xa i-phenolic glass fiber composites iphantsi kokugoba okanye ukunyanzeliswa koxinzelelo, uxinzelelo ludluliselwa ngokufanayo kwi-resin ye-matrix ukuya kwimicu yeglasi nganye ngokusebenzisa i-interface, ngokufanelekileyo ukusabalalisa amandla aphethweyo. Le nkqubo iphucula iimpawu zemishini yezinto ezidibeneyo. Ngoko ke, ukunyuka okufanelekileyoUmxholo wefiber yeglasi unokwandisa amandla ezinto ezihlanganisiweyo zefiber yeglasi yephenolic.

Iziphumo zovavanyo zibonisa oku kulandelayo:

• I-Phenolic glass fiber composites kunye ne-20% yeglasi ye-fiber contentbonisa ukuhanjiswa kwefayibha engalinganiyo, kwaye ezinye iindawo ziswele imicu.
• I-Phenolic glass fiber composites kunye ne-50% yeglasi ye-fiber contentbonisa ukuhanjiswa kwefayibha efanayo, iindawo eziqhekekileyo zokwaphuka, kwaye akukho zimpawu zibalulekileyo zokutsalwa kwefayibha. Oku kuphakamisa ukuba iifiber zeglasi zinokuthwala ngokudibeneyo umthwalo, kubangeleamandla aphezulu e-flexural.
• Xa umxholo wefiber yeglasi ungama-70%, umxholo wefiber ogqithisileyo ukhokelela kumxholo ophantsi we-matrix resin. Oku kunokubangela i-resin-poor phenomena kwezinye iindawo, kuthintele ukuhanjiswa koxinzelelo kunye nokudala ukugxilwa kwengcinezelo yendawo. Ngenxa yoko, iipropathi ezipheleleyo zoomatshini be-phenolic glass fiber composite materialzithande ukuncipha.

Ukusuka kwezi ziphumo, iUkongezwa okuphezulu okuvumelekileyo kwefiber yeglasi kwi-phenolic glass fiber composite yi-50%.

 Ukwandiswa kokuSebenza kunye neMiba enempembelelo

Ukusuka kwidatha yamanani,i-phenolic glass fiber compositesiqulethe i-50% yefiber yeglasibonisa malungakathathu amandla flexuralkwayeamaxesha amane amandla oxinzeleloxa kuthelekiswa ne-phenolic resin ecocekileyo. Ukongeza, ezinye izinto eziphembelela amandla e-phenolic glass fiber fibre reinforced plastics zibandakanyaubude bemicu yeglasikunye nabouqhelaniso.
