Pulasitiki ya polypropylene yolimbikitsidwa ndi ulusi wautali wagalasi imatanthauza zinthu zopangidwa ndi polypropylene zosinthidwa zokhala ndi ulusi wagalasi wa 10-25mm, zomwe zimapangidwa kukhala kapangidwe ka magawo atatu kudzera mu jekeseni wopangira ndi njira zina, zomwe zimafupikitsidwa ngati LGFPP. Chifukwa cha magwiridwe ake abwino kwambiri, polypropylene yolimbikitsidwa ndi ulusi wautali wagalasi imagwiritsidwa ntchito kwambiri m'magalimoto.
Makhalidwe ndi ubwino wa polypropylene yayitali yolimbikitsidwa ndi ulusi wagalasi
- Kukhazikika kwabwino kwa miyeso
- Kukana kutopa kwambiri
- Kuchita pang'ono pang'onopang'ono
- Anisotropy yaying'ono, kusintha kochepa kwa warpage
- Kapangidwe kabwino kwambiri ka makina, makamaka kukana kukhudzidwa
- Kusinthasintha kwabwino, koyenera kukonza zinthu zokhala ndi makoma owonda
Polypropylene yolimba yagalasi ya 10 ~ 25mm yokhala ndi ulusi wolimbikitsidwa ndi ulusi (LGFPP) ili ndi mphamvu zambiri, kuuma, kulimba, kukhazikika kwa mawonekedwe, komanso kupotoka pang'ono poyerekeza ndi polypropylene wamba wa 4 ~ 7mm waufupi wagalasi wolimbikitsidwa ndi ulusi (GPPP). Kuphatikiza apo, zinthu za polypropylene zolimba zagalasi zazitali sizipanga kugwedezeka kwakukulu ngakhale zitatenthedwa ndi kutentha kwa 100 ℃, ndipo zimakhala ndi kukana kugwedezeka bwino kuposa polypropylene yolimba yagalasi yayifupi.
Mu chinthu chopangidwa ndi jakisoni, ulusi wautali wagalasi umayikidwa mu netiweki ya magawo atatu. Ngakhale pambuyo poti polypropylene substrate yatenthedwa, netiweki yayitali ya ulusi wagalasi imapangabe chigoba cha ulusi wagalasi chokhala ndi mphamvu inayake, pomwe ulusi wagalasi waufupi nthawi zambiri umakhala ulusi wopanda mphamvu pambuyo pa kuyaka. Izi zimachitika makamaka chifukwa chiŵerengero cha kutalika ndi m'mimba mwake cha ulusi wolimbitsa chimatsimikiza mphamvu yolimbitsa. Zodzaza ndi ulusi wagalasi waufupi wokhala ndi chiŵerengero chofunikira chochepera 100 alibe mphamvu yolimbitsa, pomwe ulusi wautali wagalasi wokhala ndi chiŵerengero chofunikira choposa 100 umagwira ntchito yolimbitsa.
Poyerekeza ndi zipangizo zachitsulo ndi zipangizo zophatikizika ndi thermosetting, pulasitiki wautali wa ulusi wagalasi uli ndi kachulukidwe kochepa, ndipo kulemera kwa gawo lomwelo kumatha kuchepetsedwa ndi 20% mpaka 50%. Pulasitiki wautali wa ulusi wagalasi ukhoza kupatsa opanga mapangidwe osinthasintha kwambiri, monga mawonekedwe owumbidwa okhala ndi mawonekedwe ovuta. Chiwerengero cha zigawo ndi zigawo zophatikizidwa zomwe zimagwiritsidwa ntchito zimasunga ndalama zogulira nkhungu (nthawi zambiri, mtengo wa nkhungu zazitali zagalasi ndi pafupifupi 20% ya mtengo wa nkhungu zoponda zitsulo), ndipo zimachepetsa kugwiritsa ntchito mphamvu (kugwiritsa ntchito mphamvu zopangira pulasitiki zazitali zagalasi ndi 60% yokha ya zinthu zachitsulo. %~80%, 35%~50% ya zinthu za aluminiyamu), zomwe zimapangitsa kuti njira yopangira ikhale yosavuta.
Kugwiritsa Ntchito Polypropylene Yolimbikitsidwa ndi Ulusi Wautali wa Glass mu Zigawo Zamagalimoto
Polypropylene yolimbikitsidwa ndi ulusi wautali imagwiritsidwa ntchito mu chimango cha thupi la galimoto, bulaketi ya batri, gawo lakutsogolo, bokosi lowongolera, chimango chothandizira mpando, placenta yotsala, choteteza mudguard, chivundikiro cha chassis, chotchinga phokoso, chimango chakumbuyo kwa chitseko, ndi zina zotero.
Gawo lakutsogolo: Pa ma module a kutsogolo kwa magalimoto, pogwiritsa ntchito zinthu za LGFPP (LGF content 30%), imatha kuphatikiza zida zachitsulo zachikhalidwe zoposa 10 monga ma radiator, ma speaker, ma condenser, ndi ma brackets kukhala zonse; silitha dzimbiri kuposa zida zachitsulo. Kuchuluka kwake ndi kochepa, kulemera kwake kumachepetsedwa ndi pafupifupi 30%, ndipo kuli ndi ufulu waukulu wopanga. Itha kubwezeretsedwanso mwachindunji popanda kusanja ndi kukonza; imachepetsa ndalama zopangira ndipo ili ndi ubwino wodziwikiratu pakuchepetsa ndalama.
Chigoba cha thupi la chipangizo: Pa zipangizo zofewa za chipangizo, kugwiritsa ntchito zipangizo za LGFPP kuli ndi mphamvu zambiri, modulus yopindika kwambiri, komanso kusinthasintha bwino kuposa zipangizo zodzazidwa za PP. Pansi pa mphamvu yomweyo, makulidwe a kapangidwe ka chipangizo amatha kuchepetsedwa kuti achepetse kulemera, Zotsatira zonse zochepetsa thupi ndi pafupifupi 20%. Nthawi yomweyo, bulaketi yachikhalidwe ya chipangizo chamagetsi imatha kupangidwa kukhala gawo limodzi. Kuphatikiza apo, kusankha zinthu za thupi la duct yosungunula kutsogolo ndi chimango chapakati cha dashboard nthawi zambiri kumakhala chinthu chomwecho ndi chimango chachikulu cha dashboard, chomwe chingathandize kwambiri kuchepetsa kulemera.
Mpando wakumbuyo: Ikhoza kusintha chimango chachitsulo chachikhalidwe kuti ichepetse kulemera kwa 20%, ndipo ili ndi ufulu wabwino kwambiri wopanga komanso magwiridwe antchito amakina, komanso zinthu monga malo okhala okwanira.
Kufunika kwa kugwiritsa ntchito polypropylene yayitali yolimbikitsidwa ndi ulusi m'munda wamagalimoto
Ponena za kusintha zinthu, zinthu zopangidwa ndi polypropylene yolimbikitsidwa ndi ulusi wautali wagalasi zimatha kuchepetsa kulemera ndi mtengo nthawi imodzi. M'mbuyomu, zinthu zopangidwa ndi ulusi wautali wagalasi zinalowa m'malo mwa zinthu zachitsulo. M'zaka zaposachedwa, pogwiritsa ntchito ndi kupanga zinthu zopepuka, zinthu zopangidwa ndi ulusi wautali wagalasi wolimbikitsidwa ndi ulusi wagalasi pang'onopang'ono zasintha pang'onopang'ono mapulasitiki olimbikitsidwa ndi ulusi wagalasi wafupi m'zigawo zambiri zamagalimoto, zomwe zikupitilizidwa. Kafukufuku ndi kugwiritsa ntchito zipangizo za LGFPP m'magalimoto.
