Zvishandiso zvePMMA muMunda Wemotokari

Acrylic is polymethyl methacrylate, yakapfupikiswa sePMMA, imhando yepolymer polymer yakagadzirwa kubva kumethyl methacrylate polymerization, inozivikanwawo se organic girazi, ine kujeka kwepamusoro, kukwirira kwemamiriro ekunze, kuoma kwakanyanya, kuumba nyore kugadzira uye zvimwe zvakanakira, inowanzoshandiswa se chinotsiva girazi.

Iro molecular molecular mass yePMMA inenge mamiriyoni maviri, uye cheni inogadzira mamorekuru yakapfava, saka simba rePMMA rakati wedzerei, uye kusimba uye kukanganiswa kwePMMA kunosvika 7 ~ 18 nguva yakakwirira kupfuura yegirazi rakajairwa.Kana ichishandiswa se plexiglass, kunyangwe ikatsemuka, haizoputika segirazi rakajairika.

PMMA parizvino ndiyo yakanyanya kunaka mashandiro epolymer zvinhu, transmittance ye92%, yakakwira kupfuura girazi uye PC transmittance, inova iyo inonyanya kukosha maitiro ekushandisa kwakawanda.

Kupokana kwemamiriro ekunze kwePMMA zvakare yechipiri kune imwe mumapurasitiki akajairwa, ayo akakwira zvakanyanya kupfuura akajairwa PC, PA uye mamwe mapurasitiki.Pamusoro pezvo, kuomarara kwepenzura kwePMMA kunogona kusvika pa2H, iyo yakakwira zvakanyanya kupfuura mamwe mapurasitiki akajairwa sePC, uye ine yakanaka yekukwenya kuramba.

Nekuda kwehunhu hwayo hwakanakisa, PMMA yakashandiswa zvakanyanya mumotokari, zvemagetsi uye midziyo yemumba, zvinhu zvevatengi, mwenje, kuvaka uye zvekuvakisa, zvekurapa nezvimwe minda.

Zvishandiso zvePMMA muMunda Wemotokari

Kazhinji, PMMA mumotokari taillight, dashboard mask, kunze kwekona uye zvikamu zvekushongedza, mwenje wemukati, rearview mirror shell uye mamwe minda inoshandiswa, inonyanya kushandiswa mukudiwa kwekujeka, kupenya uye yakakwirira gloss uye mamwe minda.

1, PMMA inoshandiswa mumagetsi emota

Mwenje wemotokari wakakamurwa kuita mwenje wemberi uye mwenje weshure, uye zvinhu zvinoonekera zvinoshandiswa kune zvikamu zvakaita semarambi.Chiedza chemusoro uye mwenje wefog mumvuri unoshandisa polycarbonate PC zvinhu, izvi zvinodaro nekuti mukufambisa mwenje wemusoro nguva yekushandiswa inowanzorebesa, nepo mota inotyaira pamwenje wemwenje inopikisa zvinodikanwa zvakakwirira.Asi PC inoshandiswa mwenje wemberi zvakare ine tekinoroji yakaoma, mutengo wakakwira, kuchembera kuri nyore uye kumwe kukanganisa.

Taillights anowanzo shandura masaini, mabhureki mwenje, kusimba kwechiedza kwakadzikira, ipfupi sevhisi nguva, saka kupisa kunodiwa kwakadzikira, kunyanya kushandisa PMMA zvinhu, PMMA transmittance 92%, yakakwirira kupfuura 90% PC, refractive index 1.492, yakanaka yemamiriro ekunze kuramba. , kuoma kwepamusoro pepamusoro, ndiyo taillight mask, reflector, light guide yezvakanakira zvinhu.Nekuda kwekuoma kwayo kwepamusoro, PMMA ine yakanaka kukwenya kuramba uye inogona kushandiswa yakananga pasina kudzivirirwa kwepamusoro kana ichishandiswa sekunze kwechiedza machisi girazi zvinhu.Chiedza chekuparadzira PMMA ine hukuru hwekuparadzira maitiro uye iri nyore kuwana yunifomu yekuvhenekesa mhedzisiro, inova imwe yezvinhu zvakakosha mune yazvino taillight application.

2, PMMA yedashboard mask

Iyo dashboard mask inonyanya kuita basa rekudzivirira chiridzwa uye kuratidza chiridzwa data nemazvo.Instrument panel mask rinowanzo kuumbwa jekiseni, PMMA inonyanya kushandiswa, nekujeka kwakanyanya, simba rakakwana, kuomarara, kugadzikana kwakanaka kwezuva, mumhepo yezuva uye kupisa kwetsvina yeinjini pasi petembiricha yakakwira haina deformation, mukupisa kwenguva refu hakugadzirisike. , haikundikani, haikanganisi kururama kwechiridzwa.

3, Makoramu ekunze uye zvidimbu zvekucheka

Iyo mota column yakakamurwa kuita ABC koramu, maitiro ayo anodiwa anonyanya kupenya (kazhinji piyano dema), yakakwira mamiriro ekunze, kupisa kwakanyanya, kuramba kwekukwenya, zvirongwa zvinowanzo shandiswa ndeye ABS + pfapfaidzo pendi, PP + pfapfaidzo pendi uye PMMA + ABS kaviri extrusion. chirongwa, uye yakaomesesa PMMA chirongwa.Kana ichienzaniswa neyekupfapfaidza pendi chirongwa, PMMA inogona kubvisa maitiro ekupfapfaidza, yakawedzera hushamwari kwezvakatipoteredza, yakaderera mutengo, uye zvishoma nezvishoma ive chirongwa chikuru.

4, PMMA inoshandiswa kune mwenje wemukati

Mwenje wemukati unosanganisira mwenje wekuverenga uye ambiance mwenje.Mwenje yekuverengera chikamu chemagetsi emukati memotokari, kazhinji anoiswa padenga remberi kana kumashure.Kudzivirira kusvibiswa kwechiedza, marambi ekuverenga anowanzo kuparadzira mwenje, uchishandisa matte kana frosted PMMA kana PC mhinduro.

Atmosphere mwenje imhando yekuvhenekesa iyo inogona kugadzira mhepo yakagadzikana uye kuwedzera pfungwa yemotokari.Mitsetse yegwara remwenje rinoshandiswa muchiedza che ambient rakakamurwa kuita mhando mbiri: dzakapfava uye dzakaomarara zvichienderana nemagadzirirwo awo.Yakaoma mwenje dhizaini mameseji akaoma, haagone kukotama, kazhinji kuburikidza nejekiseni rekugadzira kana extrusion molding, zvinhu kuPMMA, PC uye zvimwe zvinhu zvine pachena.

5, PMMA inoshandiswa mune yekumashure yekuona girazi dzimba

Rear view mirror enclosure inonyanya kuda kupenya kwepamusoro uye kupenya kwakasviba, nepo ichida kusimba kwesimba, kukwenya kuramba uye kuramba kwemamiriro ekunze.Sezvo chimiro chegirazi ganda rinowanzo kukombama, zviri nyore kuburitsa kushushikana, saka machining kuita uye kuomarara kunodiwa kuve kwakanyanya.Yakajairika hurongwa ine ABS yekupfapfaidza pendi, asi kusvibiswa kwemaitiro kwakakomba, maitiro acho akawanda, kushandiswa kwePMMA chirongwa kunogona kubudirira kupfapfaidza mahara, kazhinji pano kushandisa yakaomeswa nhanho yezvinhu zvePMMA, kusangana neratidziro yebvunzo mukudonha kuyedza uye nezvimwe. mapurojekiti.

Izvo zviri pamusoro ndeye mashandisirwo ePMMA mumunda wemotokari, anonyanya hukama neoptics kana kutaridzika, PMMA inowedzera mamwe mikana kumunda wemotokari.
