Usetyenziso lwe-PMMA kwiNdawo yeeMoto

I-Acrylic yi-polymethyl methacrylate, efinyeziweyo njenge-PMMA, luhlobo lwepolymer ye-polymer eyenziwe kwi-methyl methacrylate polymerization, eyaziwa ngokuba yi-organic glass, kunye nokukhanya okuphezulu, ukumelana nemozulu ephezulu, ubunzima obuphezulu, ukubunjwa okulula kunye nezinye izinto eziluncedo, zihlala zisetyenziswa njenge izinto ezithatha indawo yeglasi.

I-molecular mass ye-PMMA imalunga ne-2 yezigidi, kwaye i-chain eyenza i-molecule ithambile, ngoko ke amandla e-PMMA aphakamileyo kakhulu, kwaye ukunyanzeliswa kunye nokumelana nempembelelo ye-PMMA yi-7 ~ 18 ngamaxesha aphezulu kuneglasi eqhelekileyo. Xa isetyenziswa njenge-plexiglass, nokuba yaphukile, ayizukuqhuma njengeglasi eqhelekileyo.

I-PMMA okwangoku yeyona ndlela ibalaseleyo yokusebenza kwezixhobo zepolymer ezicacileyo, ukuhanjiswa kwe-92%, ngaphezulu kweglasi kunye nokuhanjiswa kwePC, ethe yaba yeyona mpawu ibalulekileyo kwizicelo ezininzi.

Ukuchasana kwemozulu ye-PMMA kwakhona okwesibini kwiiplastiki eziqhelekileyo, eziphezulu kakhulu kune-PC eqhelekileyo, i-PA kunye nezinye iiplastiki. Ukongeza, ubulukhuni bepensile ye-PMMA bunokufikelela kwi-2H, ephezulu kakhulu kunezinye iiplastiki eziqhelekileyo ezifana nePC, kwaye inokumelana nokukrweleka komphezulu.

Ngenxa yeempawu zayo ezibalaseleyo, i-PMMA isetyenziswe ngokubanzi kwiimoto, i-electronics kunye nezixhobo zasekhaya, iimpahla zabathengi, ukukhanya, ukwakhiwa kunye nezinto zokwakha, ezonyango kunye nezinye iinkalo.

Usetyenziso lwe-PMMA kwiNdawo yeeMoto

Ngokubanzi, i-PMMA kwi-taillight yemoto, imaski yedeshibhodi, ikholamu yangaphandle kunye neendawo zokuhombisa, izibane zangaphakathi, igobolondo yesibuko esingasemva kunye nezinye iindawo zisetyenziswa, ngokukodwa zisetyenziswa kwisidingo sokungafihli, ukuguquguquka kunye neglosi ephezulu kunye nezinye iindawo.

I-1, i-PMMA esetyenziswe kwizibane zemoto

Izibane zemoto zahlulwe zaba zizibane zangaphambili kunye nezibane zasemva, kwaye izinto ezibonisa ukukhanya zisetyenziselwa iindawo ezifana nezibane zezibane. Isibane sentloko kunye nesibane sesibane senkungu sisebenzisa izixhobo ze-polycarbonate PC, oku kungenxa yokuba kwinkqubo yokuqhuba isibane sokukhanya ixesha lihlala lide, ngelixa iimoto eziqhuba kwiimfuno zokumelana nempembelelo yesibane ziphezulu. Kodwa iPC esetyenziselwa izibane zentloko ikwanayo neteknoloji entsonkothileyo, ixabiso eliphezulu, ukuguga lula kunye nezinye iintsilelo.

Izibane eziqhelekileyo zijika izibonakaliso, izibane eziqhekezayo, ukukhanya kokukhanya kuphantsi, ixesha elifutshane lenkonzo, ngoko ke iimfuno zokuxhathisa ubushushu ziphantsi ngokwentelekiso, ubukhulu becala zisebenzisa izixhobo ze-PMMA, i-PMMA transmittance 92%, ingaphezulu kwe-90% yePC, i-refractive index 1.492, ukumelana nemozulu elungileyo. , ubunzima obuphezulu bomgangatho, yimaski yomsila, isibonisi, isikhokelo esikhanyayo sezinto ezifanelekileyo. Ngenxa yobunzima bayo obuphezulu, i-PMMA inokumelana nokukrweleka okuhle kwaye inokusetyenziswa ngokuthe ngqo ngaphandle kokhuselo lomphezulu xa isetyenziswa njengesixhobo sesipili somdlalo wangaphandle. Ukusabalalisa ukukhanya kwe-PMMA kuneempawu eziphezulu zokusabalalisa kwaye kulula ukufezekisa umphumo wokukhanyisa okufanayo, enye yezinto eziphambili kwisicelo somsila wangoku.

2, PMMA yemaski yedeshibhodi

Imaski yedeshibhodi ikakhulu idlala indima yokukhusela isixhobo kunye nokubonisa idatha yesixhobo ngokuchanekileyo. Imaski yepaneli yesixhobo iqhele ukubunjwa, i-PMMA isetyenziswa ngakumbi, ngokucaca okuphezulu, amandla okwaneleyo, ukuqina, ukuzinza okuhle kwe-dimensional, kwimitha yelanga kunye nobushushu be-injini phantsi kobushushu obuphezulu ayenzi deformation, kwiqondo lobushushu elide elide aliguquki. , ayiphumeleli, ayichaphazeli ukuchaneka kwesixhobo.

3, Iikholamu zangaphandle kunye neziqwenga zokunquma

Ikholomu yemoto yahlulwe kwikholamu ye-ABC, iimfuno zayo zokusebenza ziyiglosi ephezulu (ngokubanzi ipiyano emnyama), ukumelana nemozulu ephezulu, ukumelana nobushushu obuphezulu, ukumelana nokukhuhla, iinkqubo ezisetyenziswa ngokuqhelekileyo ziyi-ABS + ipeyinti yokutshiza, ipeyinti yokutshiza ye-PP+ kunye ne-PMMA + ABS ephindwe kabini. iskimu, kunye neskimu se-PMMA esinzima. Xa kuthelekiswa nenkqubo yokupeyinta yokutshiza, i-PMMA inokuphelisa inkqubo yokutshiza, ikhuseleke ngakumbi kokusingqongileyo, ixabiso eliphantsi, kwaye ngokuthe ngcembe ibe sisikimu esiqhelekileyo.

I-4, i-PMMA isetyenziselwa izibane zangaphakathi

Izibane zangaphakathi ziquka izibane zokufunda kunye nezibane ze-ambience. Izibane zokufunda ziyinxalenye yenkqubo yokukhanyisa yangaphakathi yemoto, edla ngokuxhonywa kuphahla lwangaphambili okanye olungasemva. Ukuthintela ukungcoliseka kokukhanya, izibane zokufunda zisasaza ukukhanya, zisebenzisa i-matte okanye ifrosted PMMA okanye izisombululo zePC.

Isibane se-Atmosphere luhlobo lokukhanyisa olunokudala umoya opholileyo kunye nokuphucula ingqiqo yesithuthi. Imicu yesikhokelo sokukhanya esetyenzisiweyo ekukhanyeni kwe-ambient yahlulwe yaba ziindidi ezimbini: ithambile kwaye ilukhuni ngokwendlela yokuthungwa kwayo. Ukuthungwa kwesikhokelo sokukhanya okunzima kunzima, akukwazi ukugoba, ngokubanzi ngokubumba inaliti okanye ukubunjwa kwe-extrusion, izinto ezibonakalayo kwi-PMMA, i-PC kunye nezinye izinto ezibonakalayo.

I-5, i-PMMA isetyenziswa kwizindlu zesipili sokujonga ngasemva

Isibuko sokujonga ngasemva sifuna ubukhulu beglosi kunye nokuqaqamba okumnyama, ngelixa sifuna amandla aphezulu, ukuchasana nokukrwempa kunye nokuxhathisa imozulu. Njengoko imilo yeqokobhe lesipili igobile ngokubanzi, kulula ukuvelisa uxinzelelo, ngoko ke ukusebenza komatshini kunye nokuqina kuyafuneka ukuba kube phezulu. Iskimu esiqhelekileyo sine-ABS yokupeyinta yokutshiza, kodwa ungcoliseko lwenkqubo lunzulu, inkqubo ininzi, ukusetyenziswa kweskimu se-PMMA kunokuphumeza ukutshiza simahla, ngokubanzi apha ukusebenzisa inqanaba lokuqina lezinto ze-PMMA, ukuhlangabezana nolwandlalo lovavanyo kuvavanyo lokuthotywa kunye nezinye. iiprojekthi.

Oku ngasentla kukusetyenziswa kwesiqhelo kwe-PMMA kwintsimi yeemoto, ikakhulukazi ehambelana ne-optics okanye ukubonakala, i-PMMA yongeza amathuba amaninzi kwintsimi yeemoto.
