Mapulasitiki apadera a uinjiniya amatanthawuza mapulasitiki a uinjiniya omwe ali ndi katundu wambiri komanso kutentha kwanthawi yayitali kuposa 150 ℃.Nthawi zambiri kukana kutentha kwambiri, kukana kwa radiation, kukana kwa hydrolysis, kukana kwanyengo, kukana kwa dzimbiri, kuletsa moto kwachilengedwe, kutsika kwamafuta ochepa, kukana kutopa ndi zabwino zina.Pali mitundu yambiri yamapulasitiki apadera aumisiri, kuphatikiza polyliquid crystal polima (LCP), polyether ether ketone (PEEK), polyimide (PI), phenyl sulfide (PPS), polysulfone (PSF), polyaromatic ester (PAR), fluoropolymers (PTFE, PVDF, PCTFE, PFA), etc.
Malinga ndi mbiri yakale komanso momwe zinthu ziliri, mayiko aku Europe ndi America kuyambira pakubwera kwa polyimide m'ma 1960 ndikubwera kwa polyether ether ketone kumayambiriro kwa zaka za m'ma 1980, mpaka pano apanga mitundu yopitilira 10 yamapulasitiki apadera opanga mapulasitiki.Mapulasitiki apadera aukadaulo aku China adayamba pakati komanso kumapeto kwa zaka za m'ma 1990.Pakalipano, makampaniwa ali mu gawo loyamba la chitukuko, koma liwiro lachitukuko ndilofulumira.Mapulasitiki angapo apadera apadera amatengedwa ngati zitsanzo.
Liquid crystal polima (LCP) ndi mtundu wazinthu zonunkhira za poliyesitala zomwe zimakhala ndi mphete zambiri zolimba za benzene pamaketani akulu, zomwe zimasintha kukhala makristalo amadzimadzi pansi pa kutentha kwina, ndipo zimakhala ndi mawonekedwe abwino kwambiri.Pakalipano, mphamvu yapadziko lonse ya crystal polima yamadzimadzi ndi pafupifupi matani 80,000 / chaka, ndipo United States ndi Japan zimapanga pafupifupi 80% ya mphamvu zonse zapadziko lonse.Makampani aku China a LCP adayamba mochedwa, ndipo mphamvu zonse zopangira pano zimakwana matani 20,000 / chaka.Opanga akuluakulu akuphatikizapo Shenzhen Water New Equipment, Zhuhai Vantone, Shanghai Puliter, Ningbo Jujia, Jiangmen Dezotye, ndi zina zotero. Zikuyembekezeka kuti kumwa kwathunthu kwa LCP kudzakhalabe ndi kukula kwa 6% ndikupitirira matani 40,000 mu 2025, moyendetsedwa. ndi kufunikira kwa zida zamagetsi ndi zamagetsi ndi magawo amagalimoto.
Polyether ether ketone (PEEK) ndi semi-crystalline, thermoplastic onunkhira polima zakuthupi.Pakali pano, pali mitundu itatu ya polyether ether ketoni pamsika: utomoni wangwiro, utomoni wagalasi wosinthidwa, carbon fiber kusinthidwa.Pakali pano, Wiggs ndi omwe amapanga polyether ketone padziko lonse lapansi, ndipo amatha kupanga matani pafupifupi 7000 / chaka, zomwe zimawerengera pafupifupi 60% ya mphamvu zonse zapadziko lonse lapansi.Kukula kwaukadaulo kwa POLYEther etha ketone ku China kudayamba mochedwa, ndipo mphamvu yopanga imakhazikika ku Zhongyan, Zhejiang Pengfu Long ndi Jida Te Plastics, zomwe zimawerengera 80% ya mphamvu zonse zopanga ku China.Zikuyembekezeka kuti m'zaka zisanu zikubwerazi, kufunikira kwa PEEK ku China kudzakhalabe ndi kukula kwa 15% ~ 20% ndikufikira matani 3000 mu 2025.
Polyimide (PI) ndi onunkhira heterocyclic polima pawiri yokhala ndi imide mphete mu unyolo waukulu.Makumi asanu ndi awiri pa zana aliwonse a PI omwe amapanga padziko lonse lapansi ali ku United States, Japan, South Korea ndi mayiko ena.Kanema wa PI amadziwikanso kuti "filimu yagolide" chifukwa chakuchita bwino kwambiri.Pakali pano, pali pafupifupi 70 opanga mafilimu a polyimide ku China, omwe amatha kupanga matani pafupifupi 100.Amagwiritsidwa ntchito makamaka pamsika wotsika kwambiri, pomwe kafukufuku wodziyimira pawokha ndi chitukuko cha zinthu zapamwamba sizokwera, ndipo amatumizidwa makamaka kunja.
PPS ndi imodzi mwamitundu yofunika kwambiri komanso yodziwika bwino ya polyaryl sulfide resins.PPS ili ndi magwiridwe antchito abwino kwambiri amafuta, magwiridwe antchito amagetsi, kukana kwamankhwala, kukana ma radiation, kuletsa moto ndi zina.PPS ndi pulasitiki yapadera yaukadaulo ya thermoplastic yokhala ndi magwiridwe antchito abwino kwambiri komanso okwera mtengo.PPS nthawi zambiri imagwiritsidwa ntchito ngati zida zama polima.Amagwiritsidwa ntchito kwambiri pamagalimoto, zamagetsi ndi zamagetsi, mankhwala, makina, zakuthambo, mafakitale a nyukiliya, mafakitale azakudya ndi mankhwala osokoneza bongo ndi zina.
Kuchokera pagawo lofunsira, mapulasitiki apadera aumisiri kuphatikiza pakugwiritsa ntchito zamagetsi, magalimoto, zakuthambo, zida zolondola, ndi madera ena azikhalidwe, okhala ndi 5 g zolumikizirana, magalimoto amagetsi atsopano, cholumikizira champhamvu, zamagetsi zamagetsi, semiconductor, chisamaliro chaumoyo, mphamvu. ndi mafakitale ena, ndi chitukuko chofulumira cha kugwiritsa ntchito mapulasitiki apadera a uinjiniya akukulirakuliranso, kuchuluka ndi mtundu wa ntchito zikukwera.
Kuchokera pakusintha ndi kukonza kwapakati pamitsinje, mapulasitiki apadera aukadaulo nthawi zambiri amafunika kusinthidwa ndi magalasi / kaboni fiber reinforcement, toughening, mineral filling, antistatic, lubrication, utoto, kukana kuvala, kuphatikiza aloyi, ndi zina zambiri, kuti apititse patsogolo kufunika kwawo. .Njira zake zopangira ndi kukonzanso pambuyo pake zimaphatikizapo kusinthidwa kosakanikirana, kuumba jekeseni, filimu ya extrusion, gulu la impregnation, mbiri ya bar, makina opangira makina, omwe adzagwiritse ntchito zowonjezera zosiyanasiyana, zida zopangira, ndi zina zotero.
