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

I-Phenolic Ifayibha yeglasi, 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 esiqhelekileyo izixhobo 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 kwe-phenolic Izinto zeFayibha yeGlasis. 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-matrix izinto 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, Ifayibha yentsimbiii-s, kunye nee-mineral fibers, zidlala indima ekulungiseni amandla okuxinana kwezinto.

Ukuthwala Umthwalo kwiiComposites kunye neMpembelelo yoMxholo weFiber

Ngaphakathi iinkqubo zezinto ezidityanisiweyo zeglasi yefayibha ye-phenolic, zombini imicu 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 kwi umxholo 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 ukuba amandla 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 fiber kuthanda 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 composites eziqulethe i-50% glass fiberbonisa malunga amandla e-flexural aphindwe kathathukwaye amandla oxinzelelo aphindwe kanexa kuthelekiswa ne-phenolic resin ecocekileyo. Ukongeza, ezinye izinto ezichaphazela amandla eplastiki eziqinisiweyo zefayibha yeglasi ye-phenolic ziquka ubude beefayibha zeglasikunye nabo ulwalathiso.
