Kushandisa uye Kuvandudza Dhidhiyo yePlastiki Zvishandiso zveMotokari Nyowani dzeMagetsi

Parizvino, pasi pechirongwa chekusimudzira chepasi rose chekusimbisa zano re "double kabhoni", kuchengetedza, girini uye kudzokorodza zvave nzira yekuvandudza yezvigadzirwa zvemotokari zvitsva uye matekinoroji matsva, uye zviremu, zvakasvibirira uye kudzokorodza zvave nzira huru yekusimudzira yemotokari nyowani. zvinhu. Inotungamirwa nemafungu emotokari lightweight, mapurasitiki zvinhu zvave kunyanya kushandiswa mumunda wemotokari nekuda kwehuremu hwadzo hwekudzikisa huremu. Zvingave zvikamu zvekushongedza zvekunze zvemota, zvemukati zvekushongedza zvemukati zvakaita sepanera rezviridzwa, dhizaini remusuwo, simbi yekubatsira, chivharo chebhokisi regirovhosi, chigaro, ndiro yekumashure yevarindi, kana basa uye zvikamu zvechimiro, unogona kuona mumvuri wepurasitiki kwose kwose. Kunyanya pari zvino, mota nyowani dzemagetsi dzave nzira huru yeshanduko nekusimudzira indasitiri yemotokari yepasirese. Huremu hwemotokari dzemagetsi matsva ndeyechimbichimbi kupfuura yemotokari dzechinyakare. Iyo chiyero chekushandisa chemidziyo yepurasitiki yakawedzerwa kune nyowani simba remotokari bhatiri shell uye zvimwe zvinhu. Panguva imwecheteyo, iyo inodzoreredza murazvo, kuchengetedzwa kwakakwirira kwezvakatipoteredza, kuramba kwekukwenya, kupenya kwepamusoro, kushorwa kwecorrosion uye kumwe kuita kwemapurasitiki emotokari zvakare kunoisa kumberi matambudziko.

Iko kushandiswa kwezvinhu zvakati wandei zvepurasitiki zvinowanzo shandiswa mumotokari

PA

Polyamide PA inowanzo zivikanwa seNylon. Yakanakisa michina zvivakwa, tensile, compressive uye kupfeka kuramba. PA6, PA66, yakakwidziridzwa murazvo inodzoreredza PA6 inoshandiswa muinjini yemotokari uye injini yekutenderera zvikamu, chivharo cheinjini, chivharo cheinjini, chivharo chemusoro, silinda yemusoro, sefa yemafuta, wiper, radiator grille, nezvimwe.

PA66

PA66 yakawanikwa nepolycondensation yeadipic acid uye hexandiamine pane imwe molar ratio ye1: 1. Adipic acid inowanzogadzirwa nehydrogenation ye pure benzene uye oxidation ine nitric acid. PA66 inogonawo kuchengetedza simba rakasimba uye kuomarara pane tembiricha yepamusoro; PA66 ine yakakwira mechani simba, yakanaka kushushikana inopwanya kuramba, uye ndiyo yakanakisa kupfeka nylon; PA66 self lubricating yakanakisa, yechipiri chete kune PTFE uye polyformaldehyde; PA66 ine yakanaka yekupisa midziyo uye inodzima yega, asi kunyudza kwayo mvura kwakakura, saka kugadzikana kwayo kwakashata.

PA6+GF30

PA6 GF30 mhedzisiro yekugadziriswa kwePA6. PA6 GF30 inosimudzira zvinhu zvivakwa nekuwedzera girazi fibers. Girazi faibha pachayo ine kupisa kwekupisa, kuramba kwemurazvo, kushorwa kwecorrosion, kupisa kupisa, kusimba kwakanyanya uye kunaka kwemagetsi. Mushure mekusimbiswa negirazi fiber, PA6 GF30 zvigadzirwa zvinogona kusangana nezvinodiwa zveindasitiri uye kushandiswa kwemazuva ese, uye ine hunhu hwesimba rakanakisa, kupisa kupisa, kupikisa kupikisa uye kugadzikana kwedimensional.

PMMA+ASA

PMMA, inowanzozivikanwa se "plexiglass". Iyo ine yakanaka mwenje transmittance, mechanical zvivakwa uye yakanakisa kuchembera kuramba uye kuramba mamiriro ekunze. Asi brittleness yayo yakakwira, nyore kutsemuka, kukanganisa kuramba kwakashata.

ASA, yakafanana muchimiro neABS, inoshandisa acrylic rabha isina mbiri mabhondi panzvimbo yebutadiene rabha muABS. Iine kuchinjika kwakanakisa, kumira zvakanaka kwemamiriro ekunze, uye kuramba kuri nani kumakemikari ekuora. Asi kuoma kwayo kwepamusoro hakuna kukwirira, kuramba kwekutanga, kupfeka kuramba hakuna kunaka.

ABS

ABS is acrylonitrile - butadiene - styrene copolymer, ipurasitiki inoshanda zvakasiyana-siyana thermoplastic engineering, kupikisa kwayo, kupisa kupisa, kushomeka kwekushisa, kupikisa kemikari uye zvinhu zvemagetsi zvakanakisa, asi zvakare ine nyore kugadzirisa uye zvigadzirwa zvakanaka saizi kugadzikana, kupenya kwepasi, inonyanya kushandiswa kumotokari yemhepo inogadzirisa tuyere, chinja, midziyo yemidziyo yakatenderedza, chando chekudzivirira ndiro, zvibato zvegonhi, Bracket, chivharo chevhiri, reflector imba, fender kuchengetedza mubato, nezvimwe.

PC/ABS alloy

PC/ABS (P acrylonitrile - butadiene - styrene copolymer alloy) : zvakanakira PC yakaoma uye yakaoma, iyo yakashata ndeyekushungurudzika kuputika, viscosity; Zvakanakira ABS zvakanaka fluidity, asi yakaderera pamusoro kuoma; Nenzira iyi, iyo yakasanganiswa zvinhu P/ABS inochengeta zvakanakira zvese zviri zviviri; PC / ABS ine kuoma kwepamusoro pepamusoro, kusimba kwepamusoro uye kuoma, uye kushushikana kwakanyanya kwekuputika; Iwo ma mechanical properties pane imwe nzvimbo pakati. PC/ABS alloy mumotokari dashboard, mubato wegonhi, bracket, steering column sheath, decoration plate, air conditioning system accessories, chivharo chemota, reflector shell, tail rampshade nedzimwe nzvimbo dzakawanda dzinoshandiswa.

Kuvandudzwa kweramangwana kwemapurasitiki emotokari

Kuwedzera kudiwa kwevatengi kwemotokari dzinoita mafuta, dzinogara uye dzisina kuremerwa kunosimudzira kudiwa kwemapurasitiki muindasitiri yemotokari. Pakati pemapurasitiki anoshandiswa mumotokari, mwero wekushandiswa kwemapurasitiki akajairwa (akadai sePP, PE, PVC, ABS, nezvimwewo) anosvika makumi matanhatu muzana, nepo chiyero chekushandiswa kweinjiniya mapurasitiki (akadai sePA, PC, PBT, nezvimwe. .) inosvika 18%. Naizvozvo, kumota dzemazuvano, kungave kushongedza kwemukati, kushongedzwa kwekunze, kana chimiro chemotokari, nhamba yakakura yezvikamu zvakatanga kushandisa zvikamu zvepurasitiki pachinzvimbo chesimbi, ndiko kuti, nzvimbo yemotokari ye "plastiki pachinzvimbo. yesimbi” muitiro wakapararira.
