Yiziphi Izinzuzo Ezijwayelekile Zokusebenza ze-FRTP?

I-Fiber Reinforced Thermoplastic Composites (I-FRTP)

 

Izinto ezihlanganisiwe ze-thermoplastic eziqiniswe nge-fiber ziyingxenye ebalulekile yezinto ezihlanganisiwe. Ama-resin ahlukahlukene we-thermoplastic aqiniswaimicu yengilazi(GF),imicu ye-carbon (CF), imicu ye-aramid (AF) nezinye izinto zefiber. Izinhlanganisela ze-thermoplastic ezithuthukisiwe ze-fiber-reinforced thermoplastic zinezakhiwo ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokugqwala nokumelana nokukhathala, inqubo elula yokubumba, umjikelezo omfushane, izinga eliphezulu lokusebenzisa izinto ezibonakalayo (akukho mfucumfucu), futhi asikho isidingo sokugcinwa kwezinga lokushisa eliphansi, futhi isibe ucwaningo. i-hotspot embonini yezinto zokwakha.

 

Izinzuzo zokusebenza ezijwayelekile ze-FRTP

 

I-FRTP eyinhlanganisela ye-Thermoplastic isetshenziswe amashumi eminyaka. Uma kuqhathaniswa nezinhlanganisela ze-thermosetting ezifana ne-phenolic resin, i-urea-formaldehyde resin, i-epoxy resin, ne-polyurethane, izinhlanganisela ze-thermoplastic zinezici ezithile ezikhethekile:

 

◆Ukuminyana okuphansi namandla aphezulu:Ukuminyana kwe-FRTP kungu-1.1-1.6g/cm3, okuwu-1/5-1/7 kuphela wensimbi, 1/3-1/4 elula kune-FRP ye-thermosetting, futhi ingatholwa ngeyunithi yesisindo esincane Amandla emishini aphezulu kanye ibanga lesicelo.

 

◆Izinga elikhulu lenkululeko ekwakhiweni kokusebenza: Izakhiwo ezibonakalayo, izakhiwo zamakhemikhali, kanye nezakhiwo zemishini ze-FRTP ziklanywa ngokukhethwa okunengqondo kwezinhlobo zezinto ezingavuthiwe, izilinganiso, izindlela zokucubungula, okuqukethwe kwefayibha kanye nezindlela zokubeka. Ziningi izinto zokwakha, ezibaluleke kakhulu zihlanganisa i-polyetherketoneketone (PEKK), i-polyetheretherketone (PEEK), i-polyphenylene sulfide (PPS), inayiloni (PA), i-polyetherimide (PEI), njll. Ngakho-ke, yayo Izinga lenkululeko ekukhetheni nasekuklanyeni impahla nayo inkulu kakhulu.

 

◆Izici ezishisayo: Izinga lokushisa elijwayelekile lokusetshenziswa kwepulasitiki lingu-50-100 ℃, futhi linganyuswa libe ngaphezu kuka-100 ℃ ngemva kokuqiniswa ngefayibha yengilazi. Izinga lokushisa lokuhlanekezela ukushisa kwe-PA6 liyi-65 ° C, futhi ngemva kokuqiniswa nge-30% ye-glass fiber, izinga lokushisa lokuphazamisa ukushisa lingakhuphuka libe ngu-190 ° C. Ukumelana nokushisa kwe-PEEK kufinyelela ku-220°C. Ngemva kokuqiniswa ngo-30% we-glass fiber, izinga lokushisa lokusebenza lingakhuphuka libe ngu-310 ° C. Izinto ezihlanganisiwe ze-thermosetting azikwazi ukufeza ukumelana nokushisa okuphezulu kangako.

 

◆Ukumelana nokugqwala kwamakhemikhali: Ngokuyinhloko kunqunywa ukusebenza kwempahla ye-matrix. Kunezinhlobo eziningi zezinhlayiya ze-thermoplastic, futhi inhlaka ngayinye inezici zayo zokulwa nokubola. Ngakho-ke, i-resin ye-matrix ingakhethwa ngokuya ngendawo yokusetshenziswa kanye nezimo ezimaphakathi zezinto ezihlanganisiwe. Ngokuvamile, ingahlangabezana nezidingo zokusetshenziswa. Ukumelana namanzi kwe-FRTP nakho kungcono kunalokho kwezinhlanganisela ze-thermosetting.

 

◆Izakhiwo zikagesi: I-FRTP ngokuvamile inezinto ezinhle ze-dielectric, ayibonisi amaza omsakazo, futhi ihambisa kahle ama-microwave. Njengoba izinga lokumuncwa kwamanzi le-FRTP lilincane kunalelo le-FRP ye-thermosetting, izakhiwo zayo zikagesi zingcono kuneyakamuva. Ngemuva kokwengeza izinto ezisebenzayo ku-FRTP, ingathuthukisa ukuhamba kwayo futhi ivimbele ukukhiqizwa kukagesi omile.

 

◆Udoti ungagaywa kabusha: I-FRTP ingaphinda icutshungulwe futhi yakheke, imfucuza kanye nezinsalela zingagaywa kabusha, futhi izakhiwo ezingokoqobo nezomshini azishintshi kakhulu, futhi ngeke zidale ukungcoliswa kwemvelo. izidingo zemvelo.
