Li-fiber tse telele tse matlafalitsoeng ka thermoplastic (LFRT) li ntse li sebelisoa lits'ebetsong tsa ho bopa ente tse nang le thepa e phahameng ea mochini.Le hoja theknoloji ea LFRT e ka fana ka matla a matle, ho satalla le thepa ea tšusumetso, mokhoa oa ho sebetsana le thepa ena o phetha karolo ea bohlokoa ho fumana hore na karolo ea ho qetela e ka finyella eng.
E le hore u atlehe ho bōpa LFRT, hoa hlokahala ho utloisisa tse ling tsa litšobotsi tsa bona tse ikhethang.Ho utloisisa phapang pakeng tsa LFRT le thermoplastics e tloaelehileng e matlafalitsoeng e khothalelitse nts'etsopele ea lisebelisoa, moralo le theknoloji ea ho sebetsa ho eketsa boleng le bokhoni ba LFRT.
Phapang pakeng tsa LFRT le mekhoa e khuts'oane ea setso le likhalase tse khuts'oane tse matlafalitsoeng ke likhalase ke bolelele ba fiber.Ho LFRT, bolelele ba fiber bo lekana le bolelele ba li-pellets.Sena ke hobane boholo ba LFRTs bo hlahisoa ke pultrusion ho e-na le ho kuta metsoako.
Tlhahisong ea LFRT, tow e tsoelang pele eafiber ea khalaseroving e sa sothoeng e qala ka ho huleloa ka har'a dae bakeng sa ho roala ebe e kenngoa ka resin.Ka mor'a ho tsoa ka har'a lefu, lesela lena la polasetiki le matlafalitsoeng le sa khaotseng lea khaoloa kapa le kenngoa pelleted, hangata Seha ho fihlela bolelele ba 10 ~ 12mm.Ka lehlakoreng le leng, metsoako ea khale ea khalase e khuts'oane e na le likhoele tse khaotsoeng tse bolelele ba 3 ho isa ho 4 mm, 'me bolelele ba tsona bo tla fokotsoa ka tlase ho 2 mm ho shear extruder.
Bolelele ba fiber ho li-pellets tsa LFRT bo thusa ho ntlafatsa thepa ea mochine ea LFRT-impact resistance kapa ho tiea ho eketseha ha ho ntse ho boloka ho satalla.Hafeela likhoele li boloka bolelele ba tsona nakong ea ho bōptjoa, li tla etsa "skeleton ea ka hare" e fanang ka lisebelisoa tse phahameng tsa mechine.Leha ho le joalo, mokhoa o fosahetseng oa ho bopa o ka fetola lihlahisoa tsa fiber e telele hore e be lisebelisoa tsa fiber e khutšoanyane.Haeba bolelele ba fiber bo sekiselitsoe nakong ea ho bōptjoa, ho ke ke ha khoneha ho finyella boemo bo hlokahalang ba tshebetso.
E le ho boloka bolelele ba fiber nakong ea ho bōptjoa ha LFRT, lintlha tse tharo tsa bohlokoa li lokela ho nkoa: mochine oa ho bopa ente, motsoako oa motsoako le hlobo, le maemo a ho sebetsa.
1. Litlhokomelo tsa lisebelisoa
Potso e le 'ngoe eo hangata e botsoang mabapi le ts'ebetso ea LFRT ke: Na hoa khoneha hore re sebelise lisebelisoa tse teng tsa ho bopa ente ho bopa lisebelisoa tse.Maemong a mangata, lisebelisoa tse sebelisetsoang ho etsa metsoako ea fiber e khutšoanyane li ka boela tsa sebelisoa ho etsa LFRT.Le hoja lisebelisoa tse tloaelehileng tsa ho bopa li-fiber li khotsofatsa boholo ba likarolo le lihlahisoa tsa LFRT, liphetoho tse ling ho thepa li ka thusa hamolemo ho boloka bolelele ba fiber.
Sekoti se nang le sepheo se akaretsang se nang le karolo e tloaelehileng ea "feed-compression-metering" se loketse haholo bakeng sa ts'ebetso ena, 'me sekhahla se senyang sa fiber se ka fokotsoa ka ho fokotsa tekanyo ea khatello ea karolo ea metering.Karo-karolelano ea khatello ea karolo ea metering ea hoo e ka bang 2:1 ke e ntle ka ho fetisisa bakeng sa lihlahisoa tsa LFRT.Ha ho hlokahale ho sebelisa li-alloys tse khethehileng tsa tšepe ho etsa li-screws, libarele le likarolo tse ling, hobane ho roala ha LFRT ha ho kholo joaloka fiber ea khalase e entsoeng ka khalase e matlafalitsoeng ka thermoplastics.
Sesebelisoa se seng se ka ruang molemo tlhahlobong ea moralo ke ntlha ea nozzle.Lisebelisoa tse ling tsa thermoplastic li bonolo ho sebetsa ka ntlha e ka morao ea nozzle, e ka etsang hore ho be le tekanyo e phahameng ea ho kuta ha thepa e kenngoa ka mokoting oa hlobo.Leha ho le joalo, ntlha ena ea nozzle e ka fokotsa haholo bolelele ba fiber ea thepa e kopantsoeng ea fiber e telele.Ka hona, ho kgothaletswa ho sebelisa grooved nozzle tip / valve kopano e nang le moralo oa 100% oa "phallo ea mahala", e leng se etsang hore ho be bonolo hore likhoele tse telele li fete ka har'a molomo le ho kena karolong.
Ho phaella moo, bophara ba sekoti le lesoba la heke li lokela ho ba le boholo bo hlephileng ba 5.5m
limithara (0.250in) kapa ho feta, 'me ha hoa lokela ho ba le mahlakore a bohale.Ke habohlokoa ho utloisisa hore na thepa e phalla joang ka thepa ea ho bopa ente le ho fumana hore na ho kuta ho tla senya likhoele hokae.
Hebei Yuniu Fiberglass Manufacturing Company Limitedkemoetsi oa thepa ea fiberglass ea nang le boiphihlelo bo fetang lilemo tse 10, boiphihlelo ba lilemo tse 7 ba ho romella kantle ho naha.
Re moetsi oa thepa ea fiberglass e tala, Tse kang fiberglass roving, fiberglass khoele, fiberglass chopped strand mat, fiberglass chopped likhoele, fiberglass black mat, fiberglass lohiloeng roving, fiberglass lesela, fiberglass lesela ..Le joalo-joalo.
Haeba ho hlokahala, ka kopo ikopanye le rona ka bolokolohi.
