Mapurasitiki akagadziridzwa anoreva zvigadzirwa zvepurasitiki pahwaro hwepurasitiki-yechinangwa uye mapurasitiki einjiniya akagadziriswa nekugadziriswa nenzira dzakadai sekuzadza, kusanganisa, uye kusimbisa kunatsiridza kudzora kwemoto, simba, kusagadzikana, uye kuomarara.

Mapurasitiki akajairika anowanzove nehunhu uye hurema. Zvikamu zvepurasitiki zvakagadziridzwa hazvigone chete kugona kushanda kwesimba kweimwe simbi, asi zvakare iine huwandu hwakadzikira, kuomarara, kurwisa ngura, yakasimba kusagadzikana, yakasimba simba, uye kupfeka kuramba. Chiteedzero chezvakanakira, senge anti-vibration uye murazvo-unodzora, zvakabuda mumaindasitiri mazhinji, uye zvinoita zvisingaite kuwana chinhu chinogona kutsiva zvigadzirwa zvepurasitiki pamwero mukuru padanho rino.

Mumakore achangopfuura, iko kukurumidza kukura kwekugadzirisa uye kugadzira maindasitiri kutenderera pasirese kwakasimudzira zvakanyanya mutengi kudiwa kwemapurasitiki akachinjwa.

Muna 2018, kudiwa kweChina kwemapurasitiki akachinjwa kwasvika mamirioni gumi nemaviri emamiriyoni, gore-gore-gore kuwedzera kwe9,46%. Chidimbu chemapurasitiki akachinjika muchikamu chemotokari chiri mamirioni e4.52 matani, achiverengera 37%. Chiyero chemapurasitiki akachinjwa mune zvemukati zvemukati zvinhu zvakawedzera kusvika pamusoro pe60%. Sechinhu chakakosha kwazvo chisina kureruka mota, haigone chete kudzora kunaka kwezvikamu neinosvika makumi mana muzana, asi zvakare inoderedza mitengo yekutenga neinosvika makumi mana muzana. .

Kumwe kushandiswa kwemapurasitiki akachinjwa mundima yemotokari

Parizvino, PP (polypropylene) zvinhu uye zvakagadziridzwa PP zvinoshandiswa zvakanyanya mune zvemukati zvemukati zvikamu, zvekunze zvikamu uye zvepasi-hood zvikamu. Mune nyika dzakasimukira indasitiri yemotokari, iko kushandiswa kwePP zvigadzirwa zvemabhasikoro zvinosvika makumi matatu kubva muzana epurasitiki yemotokari, inova ndiyo inoshandiswa zvakanyanya pazvinhu zvese zvepurasitiki mumotokari. Zvinoenderana nehurongwa hwekuvandudza, panosvika gore ra2020, avhareji epurasitiki yekushandisa mota inosvika 500kg / mota, kuverenga pamusoro pe1 / 3 yezvinhu zvese zvemotokari.

Parizvino, kuchine mukaha pakati pevagadziri veplastics vekuChina nedzimwe nyika. Iro ramangwana rekuvandudza kutungamira kweakagadziridzwa mapurasitiki ane anotevera maficha:

1. Kugadziriswa kwepurasitiki;

2. Mapurasitiki akagadziridzwa akakwira-kuita, kuwanda-kushanda uye kuumbika;

3. Mari yakaderera uye kugadzirwa kwemaindasitiri akakosha epurasitiki;

4.Kushandiswa kwetekinoroji yepamusoro senge nanocomposite tekinoroji;

5.Green, kuchengetedza kwezvakatipoteredza, yakadzika kabhoni uye kudzokorodza kwepurasitiki yakachinjwa;

6.Gadzira nyowani yepamusoro-inoshanda zvinowedzera uye yakagadziridzwa yakakosha basic resin


Kusarura kushoma kwepurasitiki yakachinjwa mumidziyo yemumba

Pamusoro penzvimbo yemotokari, midziyo yemumba zvakare iri munda panoshandiswa mapurasitiki akachinjwa. China ndiye mugadziri mukuru wemidziyo yemumba. Mapurasitiki akagadziridzwa ave achishandiswa zvakanyanya mumhepo inogadzirisa uye zvimwe zvigadzirwa munguva yakapfuura. Muna 2018, kudiwa kwemapurasitiki akachinjwa mundima yemidziyo yemumba yaive matani emamirioni 4.79, achiverengera makumi mana muzana. Nekuvandudzwa kwezvigadzirwa zvepamusoro-soro, kudiwa kwepurasitiki yakashandurwa mumunda wemidziyo yemumba kwakawedzera zvishoma nezvishoma.

Kwete izvozvo chete, nekuti mapurasitiki akagadziridzwa anowanzo kuve nemagetsi akanaka, vanoita basa rakakosha mumagetsi nemagetsi emagetsi.

Simba remagetsi, kudzivirirwa kwepamusoro, uye vhoriyamu kusagadzikana kazhinji zvinokwanisika kuzadzisa izvo zvinodikanwa zvemagetsi-emagetsi zvigadzirwa zvemagetsi. Parizvino, yakaderera-magetsi magetsi emagetsi ari kusimukira munzira ye miniaturization, yakawanda-mashandiro, uye yakakwira ikozvino, iyo inoda kushandiswa kwepurasitiki zvinhu zvine simba riri nani uye yakakwirira tembiricha kuramba.

Makambani mazhinji eChinese ari kuvandudza epurasitiki dzakasarudzika dzakadai seAPA46, PPS, PEEK, nezvimwewo, kuitira kuti zvirinani kupa epurasitiki-inoshanda zvigadzirwa zvevagadziri vemidziyo yemagetsi yakaderera-magetsi. Pasi pemamiriro e5G mu2019, zvikamu zveantena zvinoda zvinhu zve-dielectric zvinogara zvichishandiswa, uye zvakaderera-dielectric zvinogara zvichidikanwa kuti zviwane yakaderera latency. Izvi zvine zvakakwirira zvinodiwa kune akachinjwa mapurasitiki uye zvakare zvinounza mikana mitsva.
