Ngokuthuthukiswa kwe-5G, isomisi sezinwele sesingene esizukulwaneni esilandelayo, futhi isidingo sokomisa izinwele komuntu siqu siyanda.I-Fiberglass eqiniswe inayiloni (PA) isiphenduke inkanyezi ngokuthula yama-casings ezomisa izinwele kanye nezinto ezisayinayo zesizukulwane esilandelayo sezomisa izinwele ezisezingeni eliphezulu.
I-Fiberglass eqiniswe i-PA66 ivamise ukusetshenziswa emibhobolweni yokomisa izinwele zekhwalithi ephezulu, okungandisa amandla futhi kwandise amandla okushisa.Kodwa-ke, njengoba izidingo zokusebenza zesomisi sezinwele ziba phezulu nangaphezulu, i-ABS, ekuqaleni okwakuyinto eyinhloko yegobolondo, yathathelwa indawo yi-fiberglass eqiniswe i-PA66.
Njengamanje, izici eziyinhloko ezithinta ukulungiswa kwezinhlanganisela ze-PA66 ze-fiberglass ezisebenza kahle kakhulu zihlanganisa ubude bemicu eqoshiwe ye-PA fiberglass, ukwelashwa okungaphezulu kwemicu eqoshiwe ye-fiberglass ye-PA kanye nobude bayo bokugcina ku-matrix.
Bese sibheka izici zokukhiqiza ze-glass fibre eqiniswe i-PA66~
ubude bePA fiberglass oqoshiwe imicu
Lapho i-fiber yengilazi iqiniswa, ubude bezintambo eziqoshiwe ze-PA zingenye yezinto eziyinhloko ezinquma izinhlanganisela eziqiniswe yi-fiber.Ku-thermoplastics eqinisiwe ye-fiberglass emfushane, ubude be-fiber buyi-0.2 ~ 0.6 mm kuphela, ngakho-ke lapho impahla yonakaliswa ngamandla, amandla ayo awanamsebenzi ngenxa yobude obufushane be-fiber, kanye nenjongo yokusebenzisa inayiloni eqinisiwe ye-fiberglass (PA). ) isebenzisa ukuqina okuphezulu namandla aphezulu efayibha ukuthuthukisa izakhiwo zemishini yenayiloni, ngakho ubude befayibha budlala indima ebalulekile kuzakhiwo zemishini zomkhiqizo.Uma kuqhathaniswa nendlela yokuqinisa ingilazi emfishane, imodulus, amandla, ukumelana nokukhasa, ukumelana nokukhathala, ukumelana nomthelela, ukumelana nokushisa kanye nokumelana nokugqokwa kwenayiloni ende yengilazi eqinisiwe kuye kwathuthukiswa, kwanwetshwa ukusetshenziswa kwayo ezimotweni, ezintweni zikagesi, emishini nasezempi. .
Ukwelashwa kwendawoi-fiberglass eqoshiwe imicu ye-PA
Amandla okubopha phakathi kwe-fiberglass ne-matrix kungenye into ebalulekile ethinta izakhiwo zemishini yezinhlanganisela.Ama-polymers aqiniswe nge-Fiberglass angenza kahle kuphela uma enza isibopho esisebenzayo sokusebenzelana kobuso.Ku-resin yengilazi eqinisiwe ye-thermosetting resin noma izinto ezihlanganisiwe ze-polar thermoplastic resin, ingaphezulu le-fiberglass lingelashwa nge-ejenti ehlanganisayo ukuze kwakheke isibopho samakhemikhali phakathi kwe-resin nengaphezulu le-fiberglass, ukuze kutholwe ukubopha okuhlanganayo okusebenzayo.
Ukugcinwa Ubude be-I-Fiberglassku-Nylon Matrix
Abantu benze ucwaningo oluningi mayelana nokuxutshwa kwe-fiberglass eqinisiwe ye-thermoplastic resin kanye nenqubo yokubumba yemikhiqizo.Kutholakala ukuthi ubude bemicu eqoshwe nge-fiberglass emkhiqizweni buhlala bukhawulelwe ngaphansi kuka-1mm, obuncishiswa kakhulu uma buqhathaniswa nobude befiber yokuqala.Khona-ke, isenzakalo sokuphuka kwe-fiber ngesikhathi sokucutshungulwa kwacwaningwa, futhi kwatholakala ukuthi izimo zokucubungula nezinye izici ezihlukahlukene zinethonya ekuqhekekeni kwefayibha.
isici semishini
Ekwakhiweni kwe-screw kanye ne-nozzle, kuyadingeka ukugwema ukuncipha kakhulu kanye noshintsho oluzumayo lwesakhiwo.Uma isiteshi sokugeleza sincane kakhulu, sizothinta ukuhamba kwamahhala kwe-glass fiber, okuzobangela umphumela wokugunda futhi kubangele ukuphuka;uma kukhona ukuguqulwa okungazelelwe kwesakhiwo, kulula kakhulu ukukhiqiza I-concentration eyengeziwe yokucindezeleka ibhubhisai-fiberglass.
Isici senqubo
1. Izinga lokushisa lomgqomo
Ububanzi bokushisa obusetshenziswa lapho kucutshungulwa ama-pellets aqinisiwe kufanele kube ngaphezu kuka-280 ° C. Lokhu kungenxa yokuthi, lapho izinga lokushisa liphakeme, i-viscosity yokuncibilika izoncishiswa kakhulu, ukuze amandla e-shear asebenza ku-fiber ancishiswe kakhulu.Futhi ukuphuka kwe-fiberglass kwenzeka ikakhulukazi esigabeni sokuncibilika kwe-extruder.ngenxa yokuthi i-fiber yengilazi yengezwe ku-polymer encibilikile, ukuncibilika kuhlanganiswe ne-glass fiber ukugoqa i-glass fiber, edlala indima yokugcoba nokuvikela.Lokhu kunciphisa ukuphuka kwe-fiber ngokweqile kanye nokuguga kwezikulufu nemiphongolo, futhi kusiza ukuhlakazeka nokusabalalisa imicu yengilazi ekuncibilikeni.
2. Izinga lokushisa lesikhunta
Indlela yokuhluleka kwe-fiberglass ekubunjweni ngokuyinhloko ukuthi izinga lokushisa lesikhunta liphansi kakhulu kunalelo lokuncibilika.Ngemuva kokuthi ukuncibilika kugeleza emgodini, ungqimba oluqandisiwe luyakhiwa odongeni lwangaphakathi ngokushesha, futhi ngokupholisa okuqhubekayo kokuncibilika, ungqimba oluyiqhwa luyakhiwa.Ugqinsi lwe-fiberglass luyaqhubeka nokwanda, ukuze ungqimba olumaphakathi olugelezayo olugelezayo lube luncane futhi lube luncane, futhi ingxenye ye-fiber yengilazi ekuncibilikeni inamathela kungqimba oluqandisiwe futhi enye isiphetho isageleza nokuncibilika, ngaleyo ndlela yakha enkulu. phuca amandla ku-fiberglass okuholela ekuqhekekeni.Ugqinsi lwesendlalelo esiqandisiwe noma ubukhulu bongqimba olugeleza ngokukhululekile luzothinta ngokuqondile ukugeleza kokuncibilika kanye nobukhulu bamandla okugunda, okubuye kuthinte izinga lomonakalo ku-fiberglass.Ugqinsi longqimba oluqandisiwe luyanda kuqala bese luncipha ngebanga ukusuka esangweni.Kuphela phakathi nendawo, ukushuba kongqimba oluqandisiwe kuyanda ngokuhamba kwesikhathi.Ngakho ekugcineni komgodi, ubude befiber buzobuyela ezingeni elide.
3. Umthelela wokuvula isivinini sesikulufai-fiberglassubude
Ukwenyuka kwesivinini se-screw kuzoholela ngokuqondile ekwandeni kwengcindezi ye-shear esebenza ku-fiberglass.Ngakolunye uhlangothi, ukwanda kwejubane lesikulufu kungasheshisa inqubo yokwenza ipulasitiki ye-polymer, kunciphise ukuncibilika kwe-viscosity, futhi kunciphise ingcindezi esebenza ku-fiber.Lokhu kungenxa yokuthi isikulufu esingamawele sihlinzeka ngamandla amaningi adingekayo ukuze sincibilike.Ngakho-ke, umthelela wesivinini sesikulufa kubude befiber unezici ezimbili eziphambene.
4. Isikhundla kanye nendlela yokwengeza i-glass fiber
Lapho i-polymer incibilika futhi ikhishwa, ngokuvamile yengezwa esikhungweni sokuqala sokuphakela ngemva kokuxutshwa ngokulinganayo.Kodwa-ke, ohlelweni lokuncibilika kwe-fiberglass enayiloni eqinisiwe (PA), i-polymer idinga ukungezwa esikhungweni sokuqala sokuphakela, futhi izoncibilika futhi yenziwe ipulasitiki.Ngemuva kwalokho, imicu eqoshiwe ye-fiberglass ye-PA yengezwa echwebeni lokuphakela elingezansi, okungukuthi, ukuphakelwa okulandelayo kuyamukelwa.Lokhu kungenxa yokuthi uma kokubili i-fiberglass kanye ne-polymer eqinile yengezwa kusukela echwebeni lokuqala lokuphakela, i-fiberglass izophuka ngokweqile ngesikhathi senqubo yokudlulisa eqinile, futhi indawo engaphakathi yesikulufu kanye nomshini kuzophinde kuxhumene ngqo ne-fibegrlass, okubangela ukuguga okukhulu nokwephuka kwemishini.
