Ma fiber aatali a reinforced thermoplastics (LFRT) akugwiritsidwa ntchito popanga ma jakisoni okhala ndi makina apamwamba kwambiri.Ngakhale teknoloji ya LFRT ingapereke mphamvu zabwino, kuuma ndi kukhudzidwa kwa zinthu, njira yopangira zinthuyi imakhala ndi gawo lofunika kwambiri podziwa momwe gawo lomaliza lingathe kukwaniritsa.
Kuti muwumbe bwino LFRT, ndikofunikira kumvetsetsa zina mwazinthu zawo zapadera.Kumvetsetsa kusiyana pakati pa LFRT ndi ma thermoplastics ochiritsira ochiritsira kwalimbikitsa chitukuko cha zipangizo, kupanga ndi kukonza teknoloji kuti kuwonjezere phindu ndi kuthekera kwa LFRT.
Kusiyana pakati pa LFRT ndi njira yachidule yachidule ndi magalasi afupikitsa opangidwa ndi magalasi ndi kutalika kwa ulusi.Mu LFRT, kutalika kwa fiber ndi kofanana ndi kutalika kwa pellets.Izi ndichifukwa choti ma LFRT ambiri amapangidwa ndi pultrusion m'malo momameta ubweya.
Popanga LFRT, kukoka kosalekeza kwagalasi ulusikuzunguliridwa kosapindika kumakokedwa koyamba mu difa kuti matitike ndikuyikidwa ndi utomoni.Pambuyo potuluka mukufa, chingwe chapulasitiki chokhazikikachi chimadulidwa kapena kudulidwa, nthawi zambiri Dulani kutalika kwa 10 ~ 12mm.Mosiyana ndi izi, magalasi amfupi omwe amapangidwa ndi magalasi amangokhala ndi ulusi wodulidwa wokhala ndi kutalika kwa 3 mpaka 4 mm, ndipo kutalika kwake kumachepetsedwa kukhala zosakwana 2 mm mu kukameta ubweya wa ubweya.
Kutalika kwa fiber mu pellets ya LFRT kumathandiza kukonza makina a LFRT-impact kukana kapena kulimba kumawonjezeka pamene kusunga kuuma.Malingana ngati ulusiwo umakhalabe kutalika kwake panthawi yowumba, umapanga "mafupa amkati" omwe amapereka makina apamwamba kwambiri.Komabe, kuumba kosauka kumatha kusintha zinthu zaulusi wautali kukhala zida zazifupi.Ngati kutalika kwa ulusi kumasokonekera panthawi yowumba, sizingatheke kukwaniritsa mlingo wofunikira wa ntchito.
Pofuna kusunga utali wa fiber panthawi ya LFRT, zinthu zitatu zofunika ziyenera kuganiziridwa: makina opangira jekeseni, chigawo ndi mapangidwe a nkhungu, ndi momwe zimapangidwira.
1. Kusamala kwa zida
Funso limodzi lomwe nthawi zambiri limafunsidwa ponena za kukonza kwa LFRT ndi: Kodi ndizotheka kuti tigwiritse ntchito zida zomangira jekeseni zomwe zilipo kale kuti tiwumbe zidazi.Nthawi zambiri, zida zomwe zimagwiritsidwa ntchito popanga zida zazifupi zitha kugwiritsidwanso ntchito popanga LFRT.Ngakhale zida zopangira ulusi zazifupi ndizokhutiritsa pazigawo zambiri za LFRT ndi zinthu, zosintha zina pazida zingathandize bwino kusunga utali wa fiber.
Chophimba chodziwikiratu chokhala ndi gawo la "feed-compression-metering" ndi choyenera kwambiri pa njirayi, ndipo kumeta ubweya wowononga wa ulusi ukhoza kuchepetsedwa mwa kuchepetsa chiwerengero cha kuponderezedwa kwa gawo la metering.Kuphatikizika kwa gawo la mita pafupifupi 2: 1 ndikobwino kwambiri pazogulitsa za LFRT.Sikoyenera kugwiritsa ntchito zopangira zitsulo zapadera kuti apange zomangira, migolo ndi mbali zina, chifukwa kuvala kwa LFRT sikuli kofanana ndi kwachikhalidwe cha magalasi odulidwa opangidwa ndi thermoplastics.
Chida china chomwe chingapindule ndi kuwunika kwapangidwe ndi nsonga ya nozzle.Zida zina za thermoplastic ndizosavuta kuzikonza ndi nsonga yokhotakhota yokhotakhota, yomwe imatha kupanga kumeta ubweya wambiri pamene zinthuzo zidabayidwa mu nkhungu.Komabe, nsonga ya nozzle iyi imatha kuchepetsa kwambiri utali wa ulusi wazinthu zazitali zazitali.Chifukwa chake, tikulimbikitsidwa kugwiritsa ntchito nsonga / valavu ya grooved ndi 100% kapangidwe ka "free flow", zomwe zimapangitsa kuti zikhale zosavuta kuti ulusi wautali udutse pamphuno ndi kulowa gawolo.
Komanso, m'mimba mwake wa mphuno ndi dzenje pachipata ayenera kukhala lotayirira kukula 5.5m
m (0.250in) kapena kupitilira apo, ndipo pasakhale m'mbali zakuthwa.Ndikofunikira kumvetsetsa momwe zinthu zimayendera kudzera mu zida zopangira jekeseni ndikuzindikira komwe kukameta ubweya kumathyola ulusi.
Malingaliro a kampani Hebei Yuniu Fiberglass Manufacturing Company Limitedndiwopanga zinthu za fiberglass wopitilira zaka 10, zaka 7 zotumizira kunja.
Ndife opanga fiberglass zopangira, monga fiberglass roving, fiberglass thonje, fiberglass akanadulidwa strand mat, fiberglass akanadulidwa zingwe, fiberglass wakuda mphasa, fiberglass woven roving, fiberglass nsalu, fiberglass nsalu..Ndi zina zotero.
Ngati mukufuna, chonde tithandizeni momasuka.
Tidzachita zonse zomwe tingathe kuti tikuthandizeni ndikukuthandizani.
