Ndi chitukuko cha 5G, chowumitsira tsitsi chalowa m'badwo wotsatira, ndipo kufunikira kwa chowumitsira tsitsi kumachulukiranso.Fiberglass yolimbitsa nylon (PA) mwakachetechete yakhala nyenyezi zowumitsa tsitsi komanso zinthu zosainira m'badwo wotsatira wazowumitsa tsitsi wapamwamba kwambiri.
Fiberglass yolimbitsa PA66 nthawi zambiri imagwiritsidwa ntchito pamilomo ya zowumitsa tsitsi zapamwamba, zomwe zimatha kuwonjezera mphamvu ndikuwonjezera kutentha.Komabe, momwe ntchito zowumitsira tsitsi zimakulirakulira, ABS, yomwe poyamba inali chinthu chachikulu cha chipolopolocho, idasinthidwa pang'onopang'ono ndi fiberglass yolimbikitsidwa PA66.
Pakalipano, zinthu zazikulu zomwe zimakhudza kukonzekera kwa magalasi opangidwa ndi fiberglass olimbikitsidwa kwambiri a PA66 amaphatikizapo kutalika kwa zingwe za PA fiberglass zodulidwa, chithandizo chapamwamba cha zingwe za fiberglass zodulidwa za PA ndi kusungirako kwake mu masanjidwewo.
Kenako tiyeni tiwone zomwe zimapangidwa ndi galasi fiber yolimbikitsidwa PA66~
kutalika kwaPA fiberglass akanadulidwa zingwe
Ulusi wamagalasi ukalimbikitsidwa, kutalika kwa zingwe za PA zodulidwa ndi chimodzi mwazinthu zazikulu zomwe zimatsimikizira zophatikizika zolimbitsa ulusi.Mu magalasi afupiafupi a fiberglass olimbitsa thermoplastics, kutalika kwa fiber ndi (0.2 ~ 0.6) mm, kotero zinthu zikawonongeka ndi mphamvu, mphamvu zake zimakhala zopanda ntchito chifukwa chautali waufupi wa ulusi, komanso cholinga chogwiritsa ntchito nayiloni yolimba ya fiberglass (PA). ) imagwiritsa ntchito kulimba kwambiri komanso mphamvu yayikulu ya ulusi kuti ipititse patsogolo zida zamakina a nayiloni, motero kutalika kwa ulusi kumagwira ntchito yofunika kwambiri pamakina a chinthucho.Poyerekeza ndi njira yachidule yolimbitsa magalasi agalasi, modulus, mphamvu, kukana kuyandama, kukana kutopa, kukana kutentha, kukana kutentha komanso kuvala kukana kwa nayiloni yayitali yamagalasi olimbikitsidwa, kukulitsa kugwiritsa ntchito kwake pamagalimoto, zida zamagetsi, makina ndi zida zankhondo. .
Pamwamba mankhwala afiberglass akanadulidwa zingwe kwa PA
Mphamvu yolumikizana pakati pa fiberglass ndi matrix ndi chinthu china chofunikira chomwe chimakhudza makina amagulu.Ma polima olimba a fiberglass amatha kuchita bwino ngati apanga mgwirizano wolumikizana bwino.Pamagalasi utomoni wolimbitsa thermosetting resin kapena polar thermoplastic resin composite, pamwamba pa fiberglass amatha kuthandizidwa ndi cholumikizira kuti apange chomangira chamankhwala pakati pa utomoni ndi pamwamba pa fiberglass, kuti mupeze kulumikizana koyenera.
Kusunga Kutalika kwaFiberglassmu Nylon Matrix
Anthu achita kafukufuku wambiri pakusakanikirana kwa fiberglass yolimbitsa utomoni wa thermoplastic ndi njira yopangira zinthu.Zimapezeka kuti kutalika kwa zingwe za fiberglass zomwe zimadulidwa nthawi zonse zimakhala zosakwana 1mm, zomwe zimachepetsedwa kwambiri poyerekeza ndi kutalika kwa ulusi woyamba.Kenako, chodabwitsa cha kusweka kwa CHIKWANGWANI panthawi yokonza zidaphunziridwa, ndipo zidapezeka kuti momwe amagwirira ntchito ndi zinthu zina zosiyanasiyana zidakhudza kusweka kwa ulusi.
zida factor
Pamapangidwe a screw ndi nozzle, ndikofunikira kupewa kuchepa kwambiri komanso kusintha kwadzidzidzi pamapangidwe.Ngati njira yotuluka ndi yopapatiza kwambiri, imakhudza kuyenda kwaulele kwa galasi fiber, yomwe imayambitsa kumeta ubweya ndikuyambitsa kusweka;ngati pali kusintha mwadzidzidzi dongosolo, n'zosavuta kwambiri kubala The owonjezera nkhawa ndende amawonongagalasi la fiberglass.
Njira factor
1. Kutentha kwa mbiya
Kutentha kwa kutentha komwe kumagwiritsidwa ntchito pokonza ma pellets olimbikitsidwa kuyenera kukhala pamwamba pa 280 ° C. Izi ndichifukwa chakuti, kutentha kwapamwamba, kutsekemera kwa kusungunuka kudzachepetsedwa kwambiri, kotero kuti mphamvu ya shear yomwe imagwira ntchito pa fiber imachepetsedwa kwambiri.Ndipo kusweka kwa fiberglass makamaka kumachitika mu gawo losungunuka la extruder.chifukwa galasi CHIKWANGWANI anawonjezera kusungunuka polima, kusungunula kusakaniza ndi galasi CHIKWANGWANI kukulunga galasi CHIKWANGWANI, amene amasewera lubricating ndi zoteteza udindo.Izi amachepetsa kwambiri CHIKWANGWANI breakage ndi kuvala zomangira ndi migolo, facilitates kubalalitsidwa ndi kugawa magalasi ulusi mu kusungunuka.
2. Kutentha kwa nkhungu
Njira ya fiberglass kulephera mu nkhungu makamaka kuti kutentha kwa nkhungu kumakhala kochepa kwambiri kuposa kusungunuka.Pambuyo pa kusungunula kumalowa muzitsulo, chisanu chozizira chimapangidwa pakhoma lamkati nthawi yomweyo, ndipo ndi kuzizira kosalekeza kwa kusungunuka, chisanu chimapangidwa.Kuchuluka kwa galasi la fiberglass kumapitirirabe kuwonjezeka, kotero kuti wosanjikiza wapakati wosasunthika umakhala wocheperako komanso wocheperako, ndipo gawo la galasi la galasi lomwe limasungunuka limamatira kumalo oundana ndipo mapeto ena amayendabe ndi kusungunuka, motero kupanga chachikulu. kukameta ubweya pa fiberglass zomwe zimapangitsa kusweka.Kuchuluka kwa chiwombankhanga chachisanu kapena kukula kwachitsulo chosasunthika kumakhudza mwachindunji kusungunuka kwa kusungunuka ndi kukula kwa mphamvu yometa ubweya, zomwe zimakhudzanso kuchuluka kwa kuwonongeka kwa fiberglass.Kuchuluka kwa gawo lachisanu kumawonjezeka ndikucheperachepera ndi mtunda kuchokera pachipata.Pakati pokha, makulidwe oundana oundana amawonjezeka ndi nthawi.Chifukwa chake kumapeto kwa chibowocho, kutalika kwa ulusiwo kumabwereranso pamlingo wautali.
3. Mphamvu ya wononga liwirogalasi la fiberglasskutalika
Kuwonjezeka kwa liwiro la screw kudzatsogolera mwachindunji kuwonjezereka kwa kumeta ubweya wa ubweya pa fiberglass.Kumbali inayi, kuwonjezereka kwa wononga liwiro kumatha kufulumizitsa ndondomeko ya pulasitiki ya polima, kuchepetsa kusungunuka kwa viscosity, ndikuchepetsa kupsinjika komwe kumachitika pa ulusi.Izi zili choncho chifukwa wononga mapasa amapereka mphamvu zambiri zofunika kuti zisungunuke.Chifukwa chake, chikoka cha screw speed pa utali wa fiber chimakhala ndi mbali ziwiri zosiyana.
4. Malo ndi njira yowonjezera galasi fiber
Polimayo akasungunuka ndi kutulutsa, nthawi zambiri amawonjezedwa pa doko loyamba lodyetsera akasakanikirana mofanana.Komabe, posungunula nayiloni (PA) yosungunuka ya fiberglass, polima iyenera kuwonjezeredwa padoko loyamba lodyetserako chakudya, ndipo imasungunuka ndikupangidwa ndi pulasitiki.Pambuyo pake, zingwe za fiberglass zodulidwa za PA zimawonjezedwa pa doko lodyera kunsi kwa mtsinje, ndiye kuti, kudyetsa kotsatira kumatengedwa.Izi ndichifukwa choti ngati magalasi onse a fiberglass ndi polima olimba akuwonjezedwa kuchokera ku doko loyamba lodyera, galasi la fiberglass lidzaphwanyidwa mopitilira muyeso, ndipo mkati mwa wononga ndi makinawo azilumikizana mwachindunji ndi fibegrlass, kuwonongeka kwakukulu kwa zida.
