Hamwe niterambere rya 5G, icyuma cyumusatsi cyinjiye mubisekuruza bizaza, kandi icyifuzo cyo kumisha umusatsi wihariye nacyo kiriyongera.Fiberglass yongerewe imbaraga nylon (PA) yahindutse bucece ibikoresho byinyenyeri byo kumisha umusatsi hamwe nibikoresho byasinywe kubisekuru bizaza byumushatsi wohejuru.
Fiberglass ishimangirwa PA66 isanzwe ikoreshwa mumajwi yumushatsi wohejuru wohejuru, ushobora kongera imbaraga no kongera ubushyuhe.Ariko, nkuko ibisabwa mumikorere yumushatsi wumusatsi bigenda byiyongera, ABS, mubyambere byari ibikoresho byingenzi byigikonoshwa, byasimbuwe buhoro buhoro na fiberglass ishimangira PA66.
Kugeza ubu, ibintu byingenzi bigira ingaruka kumyiteguro ya fiberglass ikora cyane yongerewe imbaraga za PA66 zirimo uburebure bwa PA fiberglass yaciwe imigozi, kuvura hejuru ya fiberglass yaciwe imigozi ya PA hamwe nuburebure bwayo muri matrix.
Noneho reka turebe ibintu bitanga umusaruro wa fibre fibre ikomeza PA66~
uburebure bwaPA fiberglass yaciwe imirongo
Iyo fibre yibirahure ishimangiwe, uburebure bwimigozi ya PA yaciwe ni kimwe mubintu byingenzi bigena fibre ikomezwa.Mubisanzwe bigufi bya fiberglass bishimangira thermoplastique, uburebure bwa fibre ni mm (0.2 ~ 0,6) mm gusa, iyo rero ibikoresho byangiritse ku mbaraga, imbaraga zayo ntacyo zimaze bitewe nuburebure bwa fibre ngufi, kandi intego yo gukoresha fiberglass ikomeza nylon (PA) ) ikoresha ubukana bukomeye nimbaraga nyinshi za fibre kugirango itezimbere imiterere ya nylon, bityo uburebure bwa fibre bugira uruhare runini mumiterere yibicuruzwa.Ugereranije na fibre ngufi ya fibre yongerewe imbaraga, modulus, imbaraga, kurwanya creep, kurwanya umunaniro, kurwanya ingaruka, kurwanya ubushyuhe no kwambara ibirahuri birebire bya fibre ndende ya nylon byongerewe imbaraga, byagura imikoreshereze yabyo mumodoka, ibikoresho byamashanyarazi, imashini na gisirikare .
Ubuvuzi bwo hejurufiberglass yaciwe imirongo ya PA
Imbaraga zihuza hagati ya fiberglass na matrix nikindi kintu cyingenzi kigira ingaruka kumikorere yibikoresho.Fiberglass ishimangirwa na polymers irashobora gukora neza mugihe ikora neza.Kubirahuri bya fibre byongerewe imbaraga za resmosetting resin cyangwa polar thermoplastique resin yibikoresho, ubuso bwa fiberglass burashobora kuvurwa hamwe noguhuza imiti kugirango habeho isano ya chimique hagati ya resin nubuso bwa fiberglass, kugirango ubone guhuza neza.
Uburebure bwaFiberglassmuri Nylon Matrix
Abantu bakoze ubushakashatsi bwinshi kubijyanye no kuvanga fiberglass ishimangira resinoplastique resin hamwe nuburyo bwo kubumba ibicuruzwa.Usanga uburebure bwa fiberglass yaciwe imigozi mubicuruzwa burigihe bigarukira kuri munsi ya 1mm, bigabanuka cyane ugereranije nuburebure bwa fibre yambere.Hanyuma, ikibazo cyo kumena fibre mugihe cyo gutunganya cyarigishijwe, basanga uburyo bwo gutunganya nibindi bintu bitandukanye byagize ingaruka kumeneka ya fibre.
ibikoresho
Mu gishushanyo cya screw na nozzle, birakenewe kwirinda ubugufi bukabije nimpinduka zitunguranye muburyo.Niba umuyoboro utemba ari muto cyane, bizagira ingaruka kumigendere yubusa ya fibre yibirahure, bizatera kogosha no gutera gucika;niba hari impinduka zitunguranye muburyo, biroroshye cyane kubyara Inyongera yibitekerezo byangizafiberglass.
Impamvu
1. Ubushyuhe bwa barriel
Ubushyuhe bukoreshwa mugihe cyo gutunganya pellet zongerewe imbaraga zigomba kuba hejuru ya 280 ° C.Ibi ni ukubera ko, iyo ubushyuhe buri hejuru, ubukonje bwashonga buzagabanuka cyane, kuburyo imbaraga zogukora kuri fibre zigabanuka cyane.Kumeneka kwa fiberglass ahanini bibaho mugice cyo gushonga cya extruder.kubera ko fibre yikirahuri yongewe kuri polymer yashonze, gushonga bivangwa na fibre yikirahure kugirango uzingire fibre yikirahure, igira uruhare rwo gusiga no kurinda.Ibi bigabanya gucika cyane kwa fibre no kwambara imigozi na barrale, kandi byoroshe gukwirakwiza no gukwirakwiza fibre yibirahure mu gushonga.
Ubushyuhe bukabije
Uburyo bwo kunanirwa kwa fiberglass mubibumbano ni uko ubushyuhe bwububiko buri hasi cyane ugereranije nubushonga.Iyo gushonga bimaze gutembera mu cyuho, hakozwe urwego rwakonjeshejwe ku rukuta rw'imbere ako kanya, kandi hamwe no gukonjesha guhoraho gushonga, hashyizweho urwego rwakonje.Umubyimba wa fiberglass ukomeje kwiyongera, kuburyo urwego rwagati rwisanzuye rwisanzuye ruba ruto kandi ruto, kandi igice cya fibre yikirahure mumashanyarazi gishimangira kumurongo wafunitse kandi urundi ruhande ruracyatemba hamwe no gushonga, bityo rukaba runini gukata imbaraga kuri fiberglass bikavunika.Ubunini bwurwego rwakonjeshejwe cyangwa ubunini bwurwego rutembera ubusa bizagira ingaruka ku buryo butaziguye ku gutembera gushonga hamwe n’ubunini bw’ingufu zogosha, ari nako bigira ingaruka ku rwego rwo kwangirika kwa fibre.Umubyimba wurwego rwahagaritswe ubanza kwiyongera hanyuma ukagabanuka nintera yumuryango.Gusa hagati, uburebure bwikonje bwiyongereye hamwe nigihe.Kurangiza rero cavit, uburebure bwa fibre buzagaruka kurwego rurerure.
3. Ingaruka z'umuvuduko wa screw kurifiberglassuburebure
Ubwiyongere bwumuvuduko wa screw bizahita biganisha ku kwiyongera kwimitsi yogukora ikora kuri fiberglass.Ku rundi ruhande, kwiyongera k'umuvuduko wa screw birashobora kwihutisha inzira ya plastike ya polymer, kugabanya ubukonje bwashonga, no kugabanya imihangayiko ikora kuri fibre.Ni ukubera ko impanga ebyiri zitanga ingufu nyinshi zisabwa kugirango zishonge.Kubwibyo, ingaruka zumuvuduko wa screw kuburebure bwa fibre zifite ibintu bibiri bitandukanye.
4. Umwanya nuburyo bwo kongeramo fibre
Iyo polymer yashongeshejwe kandi igasohoka, muri rusange yongerwa ku cyambu cya mbere cyo kugaburira nyuma yo kuvanga neza.Ariko, mugihe cyo gushonga gushonga kwa fiberglass yongerewe imbaraga nylon (PA), polymer igomba kongerwamo icyambu cya mbere cyo kugaburira, kandi izashonga kandi ihindurwe.Nyuma yibyo, fiberglass yaciwe imigozi ya PA yongewe kumurongo wo kugaburira hepfo, ni ukuvuga kugaburira nyuma.Ibi ni ukubera ko niba fibre yububiko hamwe na polymer ikomeye byongeweho kuva ku cyambu cya mbere cyo kugaburira, fiberglass izavunika cyane mugihe cyo gutambutsa gukomeye, kandi imbere yimbere ya screw na mashini nabyo bizahura neza na fibegrlass, bitera kwambara cyane no gutanyagura ibikoresho.
