Mapulasitiki aukadaulo apamwamba-PPO polyphenylene ether material.Kukana kutentha kwabwino, mphamvu zamagetsi, mphamvu zambiri komanso kukana kuyandama ndi zina zotero, kupatsa zida za PPO zokhala ndi zabwino zogwiritsira ntchito pamagalimoto., zida zamagetsi, 5G ndi magawo ena.
Chifukwa cha kusungunuka kwamphamvu kwambiri komanso kusayenda bwino kwa zinthu za PPO, zida zosinthidwa za PPO (MPPO) zili pamsika, ndipo zida zosinthidwa za PPO ndi njira zofunika kwambiri zosinthira.
Zotsatirazi ndizofala zosinthidwa za PPO alloy pamsika, tiyeni tiwone:
01 .PPO/PA aloyi zinthu
Zinthu za PA (nayiloni) zimakhala ndi makina abwino kwambiri, kukana kuvala, kudzipaka mafuta, kukonza kosavuta ndi zina, koma kuyamwa kwamadzi a polar kumakhala kwakukulu, ndipo kukula kwa chinthucho kumasintha kwambiri pambuyo poyamwa madzi.
Zinthu za PPO zimakhala ndi mayamwidwe otsika kwambiri, osasunthika bwino, komanso kukana kukwawa, koma kusayenda bwino.Titha kunena kuti PPO/PA alloy material imaphatikiza zinthu zabwino kwambiri ziwirizi.Zinthu za alloy izi ndi mtundu wa aloyi womwe ukukula mwachangu komanso mitundu yambiri pakati pa ma PPO alloys.Amagwiritsidwa ntchito makamaka pazigawo zamagalimoto, monga zophimba magudumu, zotumphukira za injini, ndi zina.
Tiyenera kuzindikira kuti amorphous PPO ndi crystalline PA ndizosagwirizana ndi thermodynamically, ndipo zosakaniza zawo zosavuta zimakhala zosavuta kuziyika, zimakhala ndi makina osowa, komanso zimakhala ndi phindu lochepa;njira zoyenera ziyenera kuchitidwa pofuna kupititsa patsogolo ntchito za awiriwa.kuyanjana kuti apititse patsogolo ntchito yake.Kuwonjezera cholumikizira choyenera ndikutengera njira yoyenera kumatha kupititsa patsogolo kuyanjana kwa PPO ndi PA.
02 .PPO/HIPS aloyi zinthu
Zinthu za PPO zimayenderana bwino ndi zinthu za polystyrene, ndipo zimatha kuphatikizidwa mugawo lililonse popanda kuchepetsa makinawo kwambiri.
Kuphatikizika kwa HIPS kuzinthu za PPO kumawonjezera mphamvu zowoneka bwino.Nthawi zambiri, pofuna kupititsa patsogolo mphamvu zamakina ndikusintha magwiridwe antchito, ma elastomer nthawi zambiri amawonjezeredwa ngati zosintha zolimba, monga SBS, SEBS, ndi zina zambiri.
Kuphatikiza apo, PPO palokha ndi mtundu wa polima womwe suwotchera moto, wosavuta kupanga kaboni, komanso wokhala ndi zozimitsa zokha.Poyerekeza ndi ma HIPS oyera, zinthu zoletsa malawi a PPO/HIPS alloys zitha kusinthanso kwambiri.Ndi kuchuluka kwa kuchuluka kwa PPO, kusungunuka kosungunuka ndi kusuta kwa aloyi ya polima pakuyaka kumachepa pang'onopang'ono, ndipo kuchuluka kwa kuyaka kopingasa pang'onopang'ono kumawonjezeka.
Minda yayikulu yogwiritsira ntchito: zida zamagalimoto zosagwira kutentha, zida zamagetsi ndi makina amagetsi, zida zoziziritsira nthunzi, ndi zina zambiri.
03 .PPO/PP aloyi zinthu
Mtengo ndi magwiridwe antchito a aloyi a PPO/PP ali pakati pa mapulasitiki a engineering, monga PA, ABS, fiberglass PP yayitali, PET yosinthidwa ndi PBT, ndi zina zambiri, ndipo akwanitsa kukhazikika, kulimba, kukana kutentha ndi mtengo.bwino bwino.Mapulogalamu ali m'mafakitale amagalimoto, mphamvu, mabokosi a zida, matayala onyamulira chakudya, zotengera zamadzimadzi (mapampu anyumba), ndi zina.
Ma alloys amakondedwa ndi opanga ma automaker chifukwa chogwirizana ndi mapulasitiki ena panthawi yobwezeretsanso, mwachitsanzo, amatha kusakanikirana ndi kupangidwanso ndi mapulasitiki ena opangidwa ndi PP kapena mapulasitiki osiyanasiyana opangidwa ndi polystyrene.
04 .PPO/PBT aloyi materia
Ngakhale kuti zipangizo za PBT zili ndi katundu wabwino, palinso mavuto monga hydrolysis yosavuta, kulephera kupirira madzi otentha kwa nthawi yaitali, mankhwala omwe amatha kukhala anisotropy, shrinkage shrinkage ndi warpage, etc. Kusintha kwa aloyi ndi zipangizo za PPO zingathe kusinthana bwino.zolakwika zantchito.
Malinga ndi kafukufuku wokhudzana ndi alloy material, low viscosity PPO material ndiyoyenera kusakanikirana ndi PBT material alloy, koma imafunikanso compatibilizer kuti igwirizane.
Zomwe zimagwiritsidwa ntchito popanga zida zamagetsi, zida zamagetsi zamagetsi ndi zina.
05. PPO/ABS aloyi zinthu
Zinthu za ABS zili ndi mawonekedwe a PS, omwe amagwirizana bwino ndi PPO ndipo amatha kusakanikirana mwachindunji.Zinthu za ABS zimatha kupititsa patsogolo mphamvu ya PPO, kupititsa patsogolo kusweka kwa nkhawa, ndikupatsanso PPO electroplatability, ndikusunga zinthu zina za PPO.
Mtengo wa ABS ndi wotsika kuposa wa PPO, ndipo chuma chamsika ndi chochuluka.Chifukwa ziwirizi zimagwirizana ndipo njira yopangira alloying ndiyosavuta, tinganene kuti ndi aloyi ya PPO, yomwe ili yoyenera pazigawo zamagalimoto, zida zotchingira ma elekitiroma, zida zamaofesi, makina amaofesi ndi machubu ozungulira, ndi zina zambiri.
