Kodi nkhani za thermoplastic?
M'zaka zaposachedwa, kukula kwa ma cormoclac compositic ophatikizidwa ndi thermoplastic yokhazikika, ndipo kafukufukuyu ndi chitukuko ndi chitukuko cha mitundu yotereyi ikuyamba padziko lapansi. Ma commopution opanga ma armoplastic amatanthauza ma politymers a thermoplastic (monga polyethylene (pe), polythey Carbon mbizi, galasi fiber, arylon fiber, etc.) monganso zida.
Mitundu ya mafuta a thermoplastid imaphatikizapo glasing grour (lft) yopitilira preph MT yotsimikizika MT ndi galasi manyowa okhazikika (cmt). Malinga ndi zofunikira kugwiritsa ntchito, matrin matrix amaphatikizapo PE-paprt, pelpcpes, peekpi, peekpi, ndi mitundu ina ya thermoplastic monga fiber fitc ndi mbiti. Ndi chitukuko cha ukadaulo wa thermoplastic retin matrix amapangira komanso kubwezeretsanso, kukula kwa mtundu wophatikizika ndi mwachangu. Wotentha kwambiri amawerengera zoposa 30% ya kuchuluka kwa matrix mayiko omwe ali ku Europe ku Europe ku Europe ku Europe ku Europe ku Europe ku Europe kumayiko.
Matrmoplastic matrix
Thermoplastic matrix ndi mtundu wa ma thermoplastic zinthu, imakhala ndi makina abwino komanso kukana kutentha, imatha kugwiritsidwa ntchito popanga zinthu zosiyanasiyana. Matrmoplastic matrix amadziwika ndi mphamvu yayikulu, kukana kutentha kwambiri komanso kukana bwino kuwononga.
Pakadali pano, ma rention a thermoplastic amagwiritsidwa ntchito pamunda wa ndege makamaka kumatentha kwambiri komanso kuchuluka kwa matrin matrix, kuphatikiza peek, pps ndi pei. Pakati pawo, amorphous Pei imagwiritsidwa ntchito kwambiri pamapangidwe a ndege kuposa semi-crystalline PPS ndi peek yokhala ndi kutentha kwambiri chifukwa cha kutentha kwake kochepa chifukwa cha kutentha kwake.
Thermoplastic imakhala ndi mphamvu yamakina ndi mankhwala osokoneza bongo, kutentha kwambiri kwamphamvu komanso kusokonekera kwamphamvu, kukhazikika kwamphamvu, kukonzanso bwino, kuwonjezanitsa ndi kukonza komanso kukonza.
Zojambula zophatikizika zomwe zidapangidwa ndi ma thermoplastic renrin ndikulimbikitsa zinthu zimakhala ndi zolimba, kulimba kwambiri, kukana mphamvu ndi kuwonongeka kwamphamvu. Fiber Prephin safunikanso kusungidwa pamtunda wochepa, nthawi yopanda malire yosungirako; Kuzungulira kwakanthawi kochepa, kuwotcherera, kuchita bwino kwambiri, kosavuta kukonza; Zinyalala zitha kubwezeretsedwanso; Ufulu wopanga malonda ndi waukulu, umatha kukhala wovuta, ndikupanga kusinthasintha komanso maubwino ena ambiri.
Kulimbikitsa Zinthu
Mitundu ya ma coosmoclastic amangodalira zinthu za utoto ndi ulusi wotsimikiza, komanso zogwirizana kwambiri ndi mawonekedwe a mabelani. Makina ogwirizira ma hermoplastic amaphatikiza mitundu itatu yoyambira: Kulimbikitsidwa kwa mabelani, kulimbikitsidwa kwa mabeni a firima kutalika ndi mphamvu yopitilira manyoro.
Mwambiri, ulusi wokhazikika ndi 0,2 mpaka 0.6mm kutalika kwambiri, ndipo popeza ulusimbiri umakhala wochepera 70μm kutalika kwa 20μm kumawoneka ngati ufa. Thermoplastics yolimbikitsidwa nthawi zambiri imapangidwa posakaniza ulusi mu thermoplastic. Kutalika kwa fiber ndi mawonekedwe a matrix kumapangitsa kuti zikhale zosavuta kuwonongeka. Poyerekeza ndi zida zazitali komanso zopitilira zitsamba zolimbika, gulu lazithunzi zazifupi ndizosavuta kupanga ndi kusintha kwakanthawi kochepa. Mitundu yazomera zonga zitsulo zimakonda kuumbidwa kapena kuwonongeka kuti apange zinthu zomaliza chifukwa ulusi wotsekera umakhala ndi vuto lililonse pamadzimadzi.
Kutalika kwa zitsulo zazitali za fiber nthawi zambiri kumachitika pafupifupi 20mm, omwe nthawi zambiri amakonzedwa ndi chivundikiro chokhazikika. Njira yodziwika yomwe imagwiritsidwa ntchito ndi njira yothandizira, yomwe imapangidwa ndikujambula kusakaniza kosakanikirana kwa fiber ndi thermoplastic imatukula kudzera mu kufa kwapadera kufa. Pakadali pano, mphamvu zophatikizika za peek yaitali ya peek imapitilira zoposa 200 za modumbuki zimatha kufikira 20GPa ndi kusindikiza kwa Fedm, ndi zinthuzo zikhala bwino ndi jakisoni.
Mitundu yopitilira mafashoni yopitilira muyeso imati "mosalekeza" ndipo imasiyana m'lifupi kuchokera kwa mita ingapo mpaka mamita angapo. Zopitilira zifanizo zifaniziro zambiri zimapereka anthamba, prefgs, kapena nsalu zokutira, ndi zina zotere, zimapangidwa ndi kuphatikizira matrmoplastic matrix.
Mitundu ya majeketi a fiber-olimbikitsidwa
Nawonso yotsimikizika yotsimikizika imapangidwa ndi zida zolimba zitsamba, monga fiberni yagalasi, kaboni fiber, zida za kayendedwe, ndi zinthu za matrami. Malinga ndi zinthu zosiyana zolimbitsa thupi, mafilimu wamba omwe amalimbikitsidwa amatha kugawidwa mu mawonekedwe a fiber agalasi (gfrp), carft fibern (CFRP) ndi Aframid).
Makina olimbikitsira a firie adalimbikitsa ali ndi izi:
(1) Mphamvu zapamwamba ndi modulus yayikulu;
(2) Katundu ndi chinthu chodziwika bwino;
(3) Kusakaniza koyenera ndi kulimba;
(4) Kuphatikiza kwa kuwonjezeka kwa mafuta kumafanana ndi konkriti.
Makhalidwe awa amapanga zinthu zam'madzi zitha kukwaniritsa zosowa za nyumba zamakono, kutama, katundu wolemera, mphamvu zochulukirapo komanso misewu yambiri.
Zojambula za Thermoplastic zimakhala ndi chitukuko chachikulu
Malinga ndi lipotilo, msika wopanga ma androplastic compaction amayembekezeka kuti adzafikira $ 66.2 biliyoni pofika 2030, wokhala ndi kuchuluka kwa pachaka kwa 7.8% panthawi yolosera. Kukula kumeneku kumatha kufotokozedwa kuti kukulira kwa Aferospace ndi magawo ogwira ntchito ndi kutukuka kowonjezera mu gawo lomanga. Thermoplastic amagwiritsidwa ntchito pomanga nyumba zokhalamo, zomangamanga ndi madzi. Katundu monga mphamvu zambiri, kulimba mtima, komanso kuthekera kobwezerezedwanso ndikupangitsa kuti mawonekedwe a thermoplastics amapanga njira zomanga.
Zojambula za Thermoplastic idzagwiritsidwanso ntchito kupanga akasinja osungira, zopepuka, mafelemu a pawindo, mitengo ya matelefoni, njanji, mapaipi ndi zipilala. Makampani ogulitsa pamagalimoto ndi amodzi mwa malo ofunikira. Opanga amayang'ana kwambiri kukonza mphamvu yamafuta pobwezeretsa zitsulo ndi chitsulo chopepuka chopepuka. Mwachitsanzo, kaboni limalemera mmodzi mwa magawo asanu ngati chitsulo, motero zimathandiza kuchepetsa kulemera kwa galimotoyo. Malinga ndi ku Europe Commission, chandamale cha kaboni kuti magalimoto azikhala pa kilomita mpaka 2024, zomwe zikuyembekezeka kuwonjezera kufunikira kwa masitepe a thermoplastic yopanga bwino malonda opanga.
Kuyembekezera kwa ma armoplastic kumayiko ndi kwakukulu, ndipo opanga nyumba amawononga ndalama zambiri pakufufuza ndi chitukuko. Tikukhulupirira kuti ndi zoyesayesa za aliyense mtsogolo, ukadaulo wapakhomo wophatikizika ungakhale pamalo otsogola.
