Izicelo ze-PMMA ku-Automotive Field

I-Acrylic i-polymethyl methacrylate, efushanisiwe ngokuthi i-PMMA, iwuhlobo lwe-polymer polymer eyenziwe nge-methyl methacrylate polymerization, eyaziwa nangokuthi ingilazi ye-organic, enokucaca okuphezulu, ukumelana nesimo sezulu esiphezulu, ukuqina okuphezulu, ukubunjwa okulula kokucubungula nezinye izinzuzo, ivame ukusetshenziswa njenge esikhundleni sezinto zengilazi.

Isisindo samangqamuzana esihlobene se-PMMA singaba yizigidi ezi-2, futhi iketango elakha ama-molecule athambile, ngakho amandla e-PMMA aphakeme kakhulu, futhi ukumelana nomthelela we-PMMA kuphindwe izikhathi ezingu-7 ~ 18 kunengilazi evamile. Uma isetshenziswa njenge-plexiglass, noma iphukile, ngeke iqhume njengengilazi evamile.

I-PMMA njengamanje iwukusebenza okuhle kakhulu kokubona kwezinto ze-polymer esobala, ukudluliswa kwe-92%, okuphakeme kunengilazi kanye nokudluliswa kwe-PC, osekuyizici eziyisisekelo ezibaluleke kakhulu zezinhlelo eziningi zokusebenza.

Ukumelana nesimo sezulu kwe-PMMA nakho kungokwesibili kokunye kumapulasitiki avamile, aphakeme kakhulu kune-PC evamile, i-PA namanye amapulasitiki. Ngaphezu kwalokho, ubulukhuni bepensela be-PMMA bungafinyelela ku-2H, obuphakeme kakhulu kunamanye amapulasitiki avamile njenge-PC, futhi inokumelana okuhle nokuklwebheka kwendawo.

Ngenxa yezici zayo ezinhle kakhulu, i-PMMA isetshenziswe kakhulu kwezezimoto, zikagesi kanye nezinto zikagesi zasekhaya, izimpahla zabathengi, ukukhanyisa, ukwakhiwa kanye nezinto zokwakha, ezokwelashwa neminye imikhakha.

Izicelo ze-PMMA ku-Automotive Field

Ngokuvamile, i-PMMA ku-taillight yemoto, imaskhi yedeshibhodi, ikholomu yangaphandle nezingxenye zokuhlobisa, izibani zangaphakathi, igobolondo lesibuko esibukwa ngemuva kanye nezinye izinkambu zisetshenziswa, ikakhulukazi ezisetshenziswa ngesidingo sokungafihli, ukukhanya okukhanyayo nokuphezulu kanye nezinye izinkambu.

1, i-PMMA esetshenziswa kumalambu angemuva emoto

Amalambu ezimoto ahlukene abe amalambu angaphambili namalambu angemuva, kanti izinto ezibonisa ngale zisetshenziselwa izingxenye ezifana namalambu. I-headlight ne-fog lamp shade zisebenzisa izinto ze-PC ze-polycarbonate, lokhu kungenxa yokuthi ngesikhathi sokushayela isikhathi sokusebenzisa isibani sivame ukuba side, kuyilapho izidingo zokumelana nomthelela we-lampshade ziphakeme. Kodwa i-PC esetshenziselwa izibani zangaphambili nayo inobuchwepheshe obuyinkimbinkimbi, izindleko eziphezulu, ukuguga okulula nokunye ukushiyeka.

Amalambu ngokuvamile amasiginali aphendukayo, amabhuleki amalambu, ukukhanya kuphansi, isikhathi sesevisi esifushane, ngakho-ke izidingo zokumelana nokushisa ziphansi, ikakhulukazi zisebenzisa izinto ze-PMMA, i-PMMA transmittance 92%, ingaphezulu kuka-90% PC, inkomba ye-refractive 1.492, ukumelana nesimo sezulu esihle , ubulukhuni obuphezulu bobuso, imaski ekhanyayo, isibonisi, umhlahlandlela wokukhanya wento efanelekile. Ngenxa yokuqina kwayo okuphezulu, i-PMMA inokumelana okuhle nokuklwebheka futhi ingasetshenziswa ngokuqondile ngaphandle kokuvikelwa kwendawo lapho isetshenziswa njengento yesibuko yokufanisa ukukhanya kwangaphandle. Ukusabalalisa ukukhanya kwe-PMMA kunezici ezihlakazekile eziphezulu futhi kulula ukufeza umphumela wokukhanyisa okufanayo, okungenye yezinto ezibalulekile kuhlelo lokusebenza lwamanje lwe-taillight.

2, PMMA yemaski yedeshibhodi

Imaski yedeshibhodi idlala kakhulu indima yokuvikela ithuluzi nokubonisa idatha yethuluzi ngokunembile. Imaski yephaneli yensimbi ngokuvamile ibunjwa ngomjovo, i-PMMA isetshenziswa kakhulu, ngokusobala okuphezulu, amandla anele, ukuqina, ukuzinza okuhle kwe-dimensional, emisebeni yelanga kanye nokushisa kwemfucuza yenjini ngaphansi kwezinga lokushisa eliphezulu akushintshi, ekushiseni okuphezulu kwesikhathi eside akushintshi. , ayihluleki, ayithinti ukunemba kwethuluzi.

3, Amakholomu angaphandle nezingcezu zokunquma

Ikholomu yemoto ihlukaniswe yaba ikholomu ye-ABC, izidingo zayo zokusebenza ngokuyinhloko i-gloss ephezulu (ngokuvamile i-piano emnyama), ukumelana nesimo sezulu esiphezulu, ukumelana nokushisa okuphezulu, ukumelana nokuklwebheka, izinhlelo ezisetshenziswa kakhulu i-ABS+ spray paint, PP+ spray paint and PMMA+ABS double extrusion. uhlelo, kanye nohlelo lwe-PMMA oluqinile. Uma kuqhathaniswa nohlelo lokudweba isifutho, i-PMMA ingaqeda inqubo yokufafaza, ivikele imvelo, izindleko eziphansi, futhi kancane kancane ibe uhlelo olujwayelekile.

4, i-PMMA isetshenziselwa izibani zangaphakathi

Izibani zangaphakathi zihlanganisa izibani zokufunda nezibani ze-ambience. Amalambu okufunda ayingxenye yesistimu yokukhanyisa yangaphakathi yemoto, ngokuvamile afakwa ophahleni lwangaphambili noma olungemuva. Ukuze uvimbele ukungcoliswa kokukhanya, izibani zokufunda ngokuvamile zihlakaza ukukhanya, zisebenzisa izixazululo ze-PMMA noma ze-PC ezifakwe isithwathwa.

Isibani se-Atmosphere luhlobo lokukhanyisa olungakha umoya okhululekile futhi luthuthukise umuzwa wemoto. Imicu yomhlahlandlela wokukhanya esetshenziswa ekukhanyeni okuzungezile ihlukaniswe yaba izinhlobo ezimbili: ezithambile neziqinile ngokuya ngokuthungwa kwazo. Ukuthungwa komhlahlandlela wokukhanya okuqinile kuqinile, akukwazi ukugoba, ngokuvamile ngokubumba umjovo noma ukubunjwa kwe-extrusion, okubalulekile ku-PMMA, i-PC nezinye izinto ezibonakalayo.

I-5, i-PMMA isetshenziswa esibukweni esingemuva sezindlu

Isibuko esingemuva esivalekile sidinga ukucwebezela okuphezulu nokukhanya okumnyama, kuyilapho sidinga amandla omthelela aphezulu, ukumelana nokuklwebheka kanye nesimo sezulu. Njengoba ukwakheka kwegobolondo lesibuko kuvame ukugoba, kulula ukukhiqiza ingcindezi, ngakho-ke ukusebenza komshini nokuqina kuyadingeka ukuthi kuphakame kakhulu. Uhlelo olujwayelekile lunomdwebo wokufafaza we-ABS, kepha ukungcoliswa kwenqubo kubi kakhulu, inqubo iningi, ukusetshenziswa kohlelo lwe-PMMA kungafinyelela ukuchelela mahhala, ngokuvamile lapha ukusebenzisa izinga eliqinile lezinto ze-PMMA, ukuhlangabezana nohlaka lokuhlola ekuhlolweni kokudonsa nokunye. amaphrojekthi.

Okungenhla ukusetshenziswa okujwayelekile kwe-PMMA emkhakheni wezimoto, ikakhulukazi okuhlobene nokubona noma ukubukeka, i-PMMA yengeza amathuba amaningi emkhakheni wezimoto.
