Izinto Ezilungisiweyo Eziphumeleleyo Kakhulu: I-Glass Fiber Reinforced Modified Phenolic Resin (FX-501)

Ngenxa yophuhliso olukhawulezayo kwicandelo leeplastiki eziqinisiweyo zeglasi ezenziwe ngobunjineli,izixhobo ezisekwe kwi-phenolic resinzisetyenziswa kakhulu kumashishini ahlukeneyo. Oku kungenxa yomgangatho wazo owahlukileyo, amandla aphezulu oomatshini, kunye nokusebenza kakuhle. Enye yezona zinto zibalulekileyo zeziizinto ze-resin zeglasi yefayibha ye-phenolic.

Ifayibha yeglasi yePhenolic, phakathi kweeresini zokwenziwa zokuqala eziphuhliswe kwimizi-mveliso, ngokuqhelekileyo yi-polycondensate eyenziwe yi-polymerization ye-phenols kunye ne-aldehydes xa kukho i-alkaline catalyst. Ezinye izongezo ziyangeniswa ukuze zidibanise isakhiwo se-macromolecular, zisiguqule sibe sisakhiwo se-macromolecular esinganyibilikiyo nesingenakufakwa, ngaloo ndlela sibe sisakhiwo esiqhelekileyoizixhobo zepolymer zokuseta i-thermosettingIi-resin ze-phenolic zixatyiswa kakhulu ngenxa yeempawu zazo ezibalaseleyo, kubandakanya ukungakwazi ukumelana nomlilo okugqwesileyo, ukuzinza kobukhulu, kunye namandla afanelekileyo oomatshini. Ezi mpawu ziye zakhuthaza uphando olunzulu kunye nokusetyenziswa kwezinto ze-resin ze-phenolic glass fiber resin.

Njengoko uqoqosho lwemizi-mveliso luhambela phambili ngokukhawuleza, iimfuno ezikhulayo zibekwe ekusebenzeni kwezinto zefayibha yeglasi ye-phenolic. Ngenxa yoko,iifayibha zeglasi ze-phenolic eziguqulweyo ezinamandla aphezulu kwaye ezingatshisi ubushushuziyaphuhliswa kwaye zisetyenziswa kakhulu.I-resin ye-phenolic elungisiweyo eqinisiweyo yefayibha yeglasi (FX-501)okwangoku yenye yezona zinto ziphumeleleyo nezilungisiweyo ze-phenolic glass fiber resin. Luhlobo olutsha lwezinto ze-phenolic ezilungisiweyo neziqinisiweyo ezenziwe ngokufaka iifayibha zeglasi kwi-resin matrix yokuqala ngokuxuba.

 Iipropati zoomatshini kunye neendima ezizimeleyo

I-resin yefayibha yeglasi yePhenolicidla ngokukhethwa njenge-matrixizinto ezinganyangekiyo, ezithambileyo, nezicinezelayongenxa yokuba inamandla okutyhafa, ukumelana nesinyibilikisi, kunye neempawu zayo ezintle zoomatshini ezifana nokungatshisi ilangabi.izinto zematrixNgokuyintloko isebenza njenge-binder, idibanisa zonke izinto ngokwemvelo.Iifayibha zeglasizisebenza njengeeyunithi eziphambili zokuthwala umthwalo kwizinto ezingagugiyo, zibonelela ngomthamo wokuthwala umthwalo, kwaye ukusebenza kwazo okuphezulu kuchaphazela ngokuthe ngqo isiphumo sokuqinisa kwi-matrix.

Indima yezinto ezisetyenziswa kwi-matrix kukubopha ngokuqinileyo ezinye izinto ezisetyenziswa kwi-tensile material, ukuqinisekisa ukuba imithwalo idluliselwa ngokulinganayo, isasazwe, kwaye yabelwe kwiifayibha ezahlukeneyo zeglasi. Oku kunika amandla athile kunye nokuqina kwezinto. Iifayibha eziqhelekileyo, kuquka iifayibha zeglasi, iifayibha ze-organic, iifayibha zentsimbi, kunye neefayibha zeminerali, zidlala indima ekulungiseni amandla okuxinana kwezinto.

 Ukuthwala Umthwalo kwiiComposites kunye neMpembelelo yoMxholo weFiber

In izinto ezidityanisiweyo zeglasi yefayibha ye-phenoliciinkqubo, zombiniimicu kunye ne-matrix resin zithwala umthwalo, kunye neefayibha zeglasi ezihlala zingumthwalo oyintloko. Xa ii-phenolic glass fiber composites ziphantsi koxinzelelo lokugoba okanye lokucinezelwa, uxinzelelo ludluliselwa ngokufanayo ukusuka kwi-matrix resin ukuya kwiifayibha zeglasi nganye ngokusebenzisa i-interface, nto leyo esasaza ngempumelelo amandla athwalwayo. Le nkqubo iphucula iipropati zoomatshini zezinto ezidityanisiweyo. Ke ngoko, ukonyuka okufanelekileyo kwiumxholo wefayibha yeglasi unokuphucula amandla ee-phenolic glass fiber composites.

Iziphumo zovavanyo zibonisa oku kulandelayo:

• Ii-phenolic glass fiber composites ezinomxholo we-20% weglasi fiberzibonisa ukusasazwa kwefayibha okungalinganiyo, ezinye iindawo zingenazo neefayibha.
• Ii-phenolic glass fiber composites ezinomxholo we-50% we-glass fiberibonisa ukusasazwa kwefayibha okufanayo, iindawo eziqhekekileyo ezingaqhekezwanga kakuhle, kwaye akukho zimpawu zibalulekileyo zokutsalwa kwefayibha enkulu. Oku kuthetha ukuba iifayibha zeglasi zinokuthwala umthwalo kunye, nto leyo ebangela ukubaamandla aphezulu okugoba.
• Xa umxholo wefayibha yeglasi ungama-70%, umxholo wefayibha ogqithisileyo ukhokelela kumxholo we-matrix resin ophantsi. Oku kunokubangela iziganeko "ezingekho semgangathweni we-resin" kwezinye iindawo, okuthintela ukudluliselwa koxinzelelo kunye nokudala uxinano loxinzelelo lwendawo. Ngenxa yoko, iipropati zoomatshini zizonke zezinto ezidityanisiweyo zeglasi ye-phenolic fiberkuthanda ukuncipha.

Ukusuka kwezi ziphumo,Ukongezwa okuphezulu okuvumelekileyo kwefayibha yeglasi kwii-phenolic glass fiber composites yi-50%.

 Izinto ezibangela ukuphuculwa kokusebenza kunye nefuthe

Ukusuka kwidatha yamanani,ii-phenolic glass fiber compositesequlethe i-50% yefayibha yeglasibonisa malungaamandla e-flexural aphindwe kathathukwayeamandla oxinzelelo aphindwe kanexa kuthelekiswa ne-phenolic resin ecocekileyo. Ukongeza, ezinye izinto ezichaphazela amandla eplastiki eziqinisiweyo zefayibha yeglasi ye-phenolic ziqukaubude beefayibha zeglasikunye naboulwalathiso.
