ISicelo kunye neSikhokelo soPhuhliso lweMathiriyeli yePlastiki yeZithuthi zaMandla amatsha

Okwangoku, phantsi kwenqaku eliphambili lophuhliso lwehlabathi lokugxininisa isicwangciso se-"khabhoni ephindwe kabini", ukonga, uhlaza kunye nokuhlaziywa kwakhona kube yindlela yophuhliso lwezixhobo ezintsha zeemoto kunye nobuchwepheshe obutsha, kunye ne-lightweight, izinto eziluhlaza kunye nokuhlaziywa kwakhona kuye kwaba yeyona ndlela yokuphuhlisa i-automotive entsha. izixhobo. Iqhutywa ngamaza obunzima bemoto, izixhobo zeplastiki ziye zasetyenziswa ngokubanzi kwintsimi yeemoto ngenxa yempembelelo yazo ebalaseleyo yokunciphisa ubunzima. Nokuba ngamalungu angaphandle okuhombisa imoto, iindawo zokuhombisa zangaphakathi ezifana nepaneli yesixhobo, ipaneli yomnyango, ipaneli yesixhobo esincedisayo, isigqubuthelo sebhokisi yeglavu, isihlalo, ipleyiti yokugada yangasemva, okanye umsebenzi kunye nenxalenye yesakhiwo, ungabona isithunzi seplastiki kuyo yonke indawo. Ngokukodwa ngoku, iimoto zamandla amatsha ziye zaba yeyona ndlela iphambili yotshintsho kunye nophuhliso lweshishini leemoto zehlabathi. Ubuncinci bezithuthi zamandla amatsha bungxamiseke ngakumbi kuneemoto zemveli. Umda wokusetyenziswa kwezinto zeplastiki uye wandiswa ukuya kwiqokobhe elitsha lebhetri yemoto yamandla kunye nezinye izinto. Kwangaxeshanye, i-retardant yedangatye, ukhuseleko oluphezulu lokusingqongileyo, ukuchasana nokukrweleka, iglosi ephezulu, ukumelana nokugqwala kunye nokunye ukusebenza kweeplastiki zeemoto nako kubeka imingeni ephezulu.

Ukusetyenziswa kwezinto ezininzi zeplastiki eziqhelekileyo ezisetyenziswa kwiimoto

PA

I-Polyamide PA yaziwa njengeNayiloni. Iipropati ezigqwesileyo zoomatshini, i-tensile, i-compressive kunye nokumelana nokunxiba. I-PA6, i-PA66, i-retardant ye-flame eyomeleziweyo i-PA6 isetyenziswa kwi-injini yemoto kunye neendawo ezijikelezayo ze-injini, isigqubuthelo se-injini, i-injini yokuvala i-injini, isigqubuthelo sentloko ye-cylinder, isihluzo se-oyile, i-wiper, i-radiator grille, njl.

PA66

I-PA66 ifunyenwe nge-polycondensation ye-adipic acid kunye ne-hexandiamine kwi-molar ratio ye-1: 1. I-Adipic acid idla ngokuveliswa yi-hydrogenation ye-benzene ecocekileyo kunye ne-oxidation nge-nitric acid. I-PA66 inokugcina amandla aqinileyo kunye nokuqina kwiqondo lokushisa eliphezulu; I-PA66 inamandla omatshini aphezulu, ukuxhathisa okulungileyo kokuqhekeka, kwaye yeyona nayiloni yokumelana nokunxiba; PA66 self lubricating ebalaseleyo, okwesibini kuphela PTFE kunye polyformaldehyde; I-PA66 inepropathi efanelekileyo ye-thermal kwaye iyimpahla yokuzicima, kodwa ukufunxa kwamanzi kukhulu, ngoko ke ukuzinza kwayo kwe-dimensional kubi.

PA6+GF30

I-PA6 GF30 sisiphumo sokuguqulwa kwe-PA6. I-PA6 GF30 yongeza iipropati zezinto ngokudibanisa iifiber zeglasi. Ifayibha yeglasi ngokwayo inokumelana nobushushu, ukuxhathisa idangatye, ukuxhathisa umhlwa, ukugquma ubushushu, ukomelela okuphezulu kunye nokufakelwa kombane okulungileyo. Emva kokuqiniswa yifayibha yeglasi, iimveliso ze-PA6 GF30 zinokuhlangabezana neemfuno zokusetyenziswa kwemizi-mveliso kunye nemihla ngemihla, kwaye zineempawu zamandla abalaseleyo, ukumelana nobushushu, ukuchasana nempembelelo kunye nokuzinza komda.

PMMA+ASA

I-PMMA, eyaziwa ngokuba yi "plexiglass". Inokuhanjiswa kokukhanya okulungileyo, iipropathi zoomatshini kunye nokumelana nokuguga okugqwesileyo kunye nokumelana nemozulu. Kodwa i-brittleness yayo iphezulu, kulula ukuyiqhekeza, ukuxhathisa impembelelo kumbi.

I-ASA, efana nesakhiwo kwi-ABS, isebenzisa irabha ye-acrylic ngaphandle kweebhondi eziphindwe kabini endaweni yerabha ye-butadiene kwi-ABS. Inokuguquguquka okugqwesileyo, ukumelana nemozulu elungileyo, kunye nokumelana ngcono kwimichiza yokubola. Kodwa ubunzima bayo bomphezulu abukho phezulu, ukuchasana nokukrala, ukumelana nokunxiba akulunganga.

ABS

I-ABS yi-acrylonitrile - butadiene - styrene copolymer, yiplastiki yobunjineli be-thermoplastic eguquguqukayo, ukuxhathisa impembelelo, ukumelana nobushushu, ukumelana nobushushu obuphantsi, ukuxhathisa imichiza kunye neempawu ezibalaseleyo zombane, kodwa kwakhona inokulungiswa okulula kunye nemveliso yozinzo oluhle lobukhulu, isicwebezelisi somhlaba, ikakhulu isetyenziselwa automotive air conditioning tuyere, switsha, amacandelo isixhobo ngeenxa zonke, ipleyiti yokukhusela umkhenkce, iziphatho zocango, isibiyeli, isigqubuthelo sevili, isibonisi sezindlu, umqheba wokhuseleko lwefender, njl.

PC / ABS ingxubevange

I-PC / ABS (i-P acrylonitrile - butadiene - styrene copolymer alloy) : inzuzo ye-PC inzima kwaye inzima, i-disadvantage yi-stress cracking, i-viscosity; Iingenelo ze-ABS zi-fluidity ezilungileyo, kodwa ubunzima obuphantsi komhlaba; Ngale ndlela, izinto ezixutyiweyo zeP/ABS zigcina izibonelelo zazo zombini; I-PC / i-ABS inobunzima obuphezulu bomhlaba, ukuqina okuphezulu kunye nokuqina, kunye nokuxhatshazwa koxinzelelo oluphezulu; Iimpawu zayo zomatshini ziphakathi. I-PC/ABS ingxubevange kwideshibhodi yemoto, isiphatho socango, isibiyeli, isingxobo sekholamu yokuqhuba, ipleyiti yokuhombisa, izixhobo zokulungisa umoya, isigqubuthelo sevili lemoto, iqokobhe lokubonisa, isibane somsila kunye nezinye iindawo ezininzi zisetyenziswa.

Uphuhliso lwexesha elizayo lweeplastiki zemoto

Ukonyuka kwemfuno yabathengi yezithuthi ezingasebenzisi mafutha, eyomeleleyo kunye nezikhaphukhaphu kuya kuvuselela imfuno yeeplastiki kushishino lweemoto. Phakathi kweeplastiki ezisetyenziselwa iimoto, izinga lokusetyenziswa kweeplastiki eziqhelekileyo (ezifana ne-PP, i-PE, i-PVC, i-ABS, njl. njl.) i-akhawunti malunga ne-60%, ngelixa izinga lokusetyenziswa kweeplastiki zobunjineli (ezifana ne-PA, i-PC, i-PBT, njl. ) Ibalelwa malunga ne-18%. Ke ngoko, kwiimoto zanamhlanje, nokuba kukuhombisa kwangaphakathi, umhombiso wangaphandle, okanye ubume bemoto, inani elikhulu lamalungu sele eqalisile ukusebenzisa iinxalenye zeplastiki endaweni yentsimbi, oko kukuthi, ibala leemoto “leplastiki endaweni yoko. yentsimbi” umkhwa okhoyo.
