Yazvino Mamiriro uye Ramangwana reZvishandiso Zvinosanganiswa muChina's Rail Transit Indasitiri

1, Industry status quo
Parizvino, mazhinji eChinese transportation kuvaka kuchiri kushandisa yakajairwa reinforced kongiri nesimbi sechinhu chikuru chekuvakisa.Nekuenderera mberi kwekuwedzera kwenguva yekushandiswa, matambudziko akasiyana-siyana ekuchembera nekukuvara akabuda, uye kune matambudziko akadai sekutambisa zviwanikwa uye kusasimba.Kuti usangane nezvinodiwa zveyazvino yekufambisa nzvimbo yekuvaka, zvinodikanwa kugadzira uye kushandisa zvimwe zvitsva uye zvine hushamwari zvekuvaka.Pakati pazvo, fiber composite zvinhu zviri kuwedzera kufarirwa nevanhu nekuda kwekuita kwavo kwepamusoro, uye zvakashandiswa zvakanyanya muaerospace, kugadzira mota, uye kugadzirwa kwemaindasitiri.

2, Tekinoroji budiriro maitiro
Kubva pamaonero ehunyanzvi, maererano nezvinodiwa zvakasiyana zvekuvandudza njanji yeramangwana, tekinoroji yefiber material inofanirwa kuiswa zvinoenderana nechirongwa chebudiriro yenyika:
Chekutanga, zvichibva pane zvakakwirira zvekuchengetedza zvinodiwa zvekuchengetedza, kushingaira uye kungoita chengetedzo, uye nyevero yenjodzi, murazvo unodzosera polyimide, murazvo unodzoreredza Lyocell fiber, aramid fiber, nezvimwewo zvichibva pamukati memoto retardancy, degradability, uye yakaderera VOC yakagadzirwa, kuwana yakakwira murazvo retadancy yezvinhu zvemukati;Isu takagadzira activated kabhoni fiber sefa zvinhu, kunyunguduka isina-yakarukwa jira cellulose sefa yekudzivirira mafirimu, uye yakawana kucheneswa kwemhepo kunoenderana nano inoshanda zvinhu.
Chechipiri, zvichibva pane zvemhando yepamusoro zvinodiwa zvekunyaradza kwakazara, zvinhu zvehuinjiniya, kuzunguzika uye ruzha optimization, uye kufamba kwakangwara, lightweight composite toughened fiber zvinhu zvakagadziridzwa, izvo zvinogona kuita mabasa akadai sekuvhunduka, kuderedza ruzha, insulation, uye. thermal insulation.
Chechitatu, zvichibva pane zvakakosha zvinodikanwa zvehigh-speed maglev, zvitima zvakabatana, uye kuderera kupikisa kukwira-kumhanya kwekufambisa, carbon fiber prepregs, composite material sheets, mashizha, zvikamu zvemaindasitiri, makanda akareruka uye zvikamu zvekufambisa njanji uye motokari, drone shells. , mapapiro, nezvimwe zvakagadziridzwa uye zvakashandiswa zvakanyanya mumaindasitiri, aerospace, njanji yekufambisa uye mamwe minda.

Yechina yakavakirwa pahuchenjeri hwepamusoro kudiwa kwekutyaira kwakangwara, kugadzira zvine hungwaru, uye nehungwaru mashandiro nekugadzirisa, uchishandisa data hombe uye blockchain tekinoroji kuvaka fiber zvinhu zvikumbiro mukati mehupenyu hwese.Iine internet data chikuva, yakavimbika digitalization yekuteedzera zvinhu inogona kuwanikwa.
Yechishanu yakavakirwa pakuda kwesimba idzva resimba, kudzokorodza zvinhu, yakaderera-kabhoni uye yakaderera emissions, ine tarisiro yegirinhi kuchengetedzwa kwezvakatipoteredza, uye yakagadzira emukati madhizaini akavakirwa pane zvinodzokororwa uye biodegradable zvinhu.

Kune ambotaurwa pamusoro pebudiriro hotspots, China yakaunganidza akakodzera indasitiri zvikwata zvekutsvagisa kuti zvigadzirise uye ikawana mimwe mibairo.Nezvekudzoreredza murazvo wepamusoro uye zvinodiwa zvekuchengetedzwa kwezvakatipoteredza zvezvishandiso zveramangwana zvenjanji, China iri kugadzira tambo dzenguva refu dzinochengetedza moto unodzoreredza nharaunda se tekinoroji nyowani yekudzokorodza inodzokorodza yefiber inodzoreredza zvinhu.Kubva pakuona kwekushanda masterbatch kuwedzera kwekugadzirisa, kuchinjwa kwemoto kunopisa kunogona kushandiswa kune zvakasiyana-siyana zvemakemikari fiber zvigadzirwa, zvichipa nzira itsva yekuongorora uye kuwanikwa kwemaitiro emangwana anopisa moto.Panyaya yesimba rakananga uye kuomarara, kabhoni faibha parizvino ndeimwe yemhando yepamusoro-inoshanda fiber zvinhu, uye yakashandiswa zvakanyanya mumidziyo yekufambisa njanji.Chikwata chekutsvagisa cheQingdao University chakagadzira inoshanda, yakanakira, uye yakaderera-mutengo kabhoni faibha composite friction material nekuita shanduko tsvakiridzo pamusoro pekabhoni fibers.Boka rekutsvagisa reSichuan University rakagadzira uye rakagadzira yakakwirira-inoshanda polyamide resin.Chikwata chavo chakagadzira yakakwirira-tembiricha inodzivirira semi anonhuwirira nylon (PA6T) uye yayo maindasitiri tekinoroji.Iyo inopisa deformation tembiricha yechigadzirwa ichi inodarika 280 ℃, uye ine yakanakisa kunyunguduka kugadzirisa fluidity, iyo inokwanisa kusangana nepamusoro-inoita kusimudzira kwemagetsi nemagetsi emagetsi akanangana nekupisa kupisa, mutete-madziro, chaiyo jekiseni kuumba, uye zvimwe zvinhu.Pamusoro pezvo, yepamusoro-soro semi anonhuwirira polyamide thermoplastic elastomers TPA uye semi anonhuwirira polyamide akagadzirwa, ane zvakanaka mashandisirwo muminda yakaita semotokari.

High performance fiber based composite zvinhu zvinowanzo shandiswa muzvinhu zvisingatakuri zvinhu zvakadai sekushongedza kwemukati kwemutyairi, koni yemutyairi, hood, chigaro chevatyairi, mapaneru emadziro epadivi, mapaneru edenga, uye mavhavha embiru dzemusuwo mune njanji yekufambisa zvinhu.High performance insulation bepa rinoshandiswawo mumakiyi ekudzivirira zvinhu mumamotor-simba, ma transformer, uye midziyo yemagetsi.Tichifunga nezvezvinhu zvakasiyana-siyana senge kuita kwakanaka kwezvinhu uye mutengo, timu yekutsvagisa yeWuhan Textile University yakagadzira yakakwirira-simba uye yakakwira modulus polyphenylene sulfide uye liquid crystal polyarylester fibers, iyo yakasimudzirwa uye inoshandiswa mumidziyo yekufambisa njanji.
