Acrylic ndi polymethyl methacrylate, yofupikitsidwa ngati PMMA, ndi mtundu wa polima polima wopangidwa kuchokera ku methyl methacrylate polymerization, yomwe imadziwikanso kuti organic galasi, yowonekera kwambiri, kukana kwanyengo, kuuma kwakukulu, kuumba kosavuta ndi maubwino ena, nthawi zambiri amagwiritsidwa ntchito ngati cholowa m'malo galasi.
Ma molekyulu a PMMA ndi pafupifupi 2 miliyoni, ndipo mamolekyu omwe amapanga unyolo ndi ofewa, kotero mphamvu ya PMMA ndi yokwera kwambiri, ndipo kukana kwamphamvu ndi kukhudzidwa kwa PMMA ndi 7 ~ 18 nthawi zambiri kuposa magalasi wamba. Ikagwiritsidwa ntchito ngati plexiglass, ngakhale itasweka, sidzaphulika ngati galasi wamba.
PMMA pakadali pano ndiyowoneka bwino kwambiri pakupanga zinthu zowoneka bwino za polima, ma transmittance 92%, apamwamba kuposa magalasi ndi ma PC transmittance, zomwe zakhala zofunikira kwambiri pazogwiritsa ntchito zambiri.
Kukaniza kwanyengo kwa PMMA ndikwachiwiri kwa mapulasitiki wamba, omwe ndi apamwamba kwambiri kuposa PC wamba, PA ndi mapulasitiki ena. Kuphatikiza apo, kuuma kwa pensulo ya PMMA kumatha kufika ku 2H, komwe kumakhala kokwera kwambiri kuposa mapulasitiki ena wamba monga PC, ndipo kumakhala ndi kukana kopanda bwino.
Chifukwa cha makhalidwe ake abwino kwambiri, PMMA yakhala ikugwiritsidwa ntchito kwambiri mu magalimoto, zamagetsi ndi zipangizo zapakhomo, katundu wogula, kuyatsa, zomangamanga ndi zomangamanga, zamankhwala ndi zina.
Kugwiritsa ntchito PMMA mu Magalimoto Oyendetsa Magalimoto
Ambiri, PMMA mu galimoto taillight, dashboard chigoba, ndime akunja ndi mbali zokongoletsera, magetsi mkati, chakumbuyo galasi chipolopolo ndi minda ina ntchito, makamaka ntchito kufunika translucent ndi mkulu gloss ndi zina.
1, PMMA yogwiritsidwa ntchito muzowunikira zam'mbuyo zamagalimoto
Nyali zamagalimoto zimagawidwa kukhala nyali zakutsogolo ndi zam'mbuyo, ndipo zida zowonekera zimagwiritsidwa ntchito ngati zounikira. Nyali yakumutu ndi mthunzi wa nyali wa chifunga zimagwiritsa ntchito zida za PC za polycarbonate, izi ndichifukwa choti pakuyendetsa nyali yamoto nthawi zambiri imakhala yayitali, pomwe magalimoto oyendetsa pampando wa lampshade ndi apamwamba. Koma PC yogwiritsidwa ntchito pakuwunikira imakhalanso ndi zovuta zamakono, zotsika mtengo, kukalamba kosavuta ndi zofooka zina.
Taillights zambiri kutembenukira siginecha, magetsi ananyema, kuwala kwambiri ndi otsika, yochepa utumiki nthawi, kotero kutentha kukana zofunika ndi otsika, makamaka ntchito zipangizo PMMA, PMMA transmittance 92%, apamwamba kuposa 90% PC, refractive index 1.492, zabwino nyengo kukana , kuuma kwapamwamba kwambiri, ndi chigoba chowala, chowunikira, chowongolera chowunikira chazinthu zoyenera. Chifukwa cha kuuma kwake kwakukulu, PMMA ili ndi kukana kwabwino kokanda ndipo imatha kugwiritsidwa ntchito mwachindunji popanda chitetezo chapamtunda ikagwiritsidwa ntchito ngati zida zagalasi zowunikira kunja. Kuwala kobalalitsa PMMA kumakhala ndi mikhalidwe yobalalika kwambiri ndipo ndikosavuta kukwaniritsa kuyatsa kofananira, chomwe ndi chimodzi mwazinthu zofunika kwambiri pakugwiritsa ntchito taillight pano.
2, PMMA ya dashboard chigoba
Chigoba cha dashboard makamaka chimagwira ntchito yoteteza chida ndikuwonetsa chidziwitso cha chidacho molondola. Chigoba cha gulu la zida nthawi zambiri chimapangidwa ndi jekeseni, PMMA imagwiritsidwa ntchito kwambiri, kuwonekera kwambiri, mphamvu zokwanira, kuuma, kukhazikika kwabwino, mu radiation yadzuwa ndi kutentha kwa injini kutentha kwambiri sikumapindika, kutentha kwanthawi yayitali sikumapindika. , sichilephera, sichimakhudza kulondola kwa chida.
3, Zipilala Zakunja ndi zidutswa zochepetsera
Mzere wamagalimoto wagawidwa m'gawo la ABC, zomwe zimafunikira pakuchita kwake ndizowala kwambiri (nthawi zambiri piyano yakuda), kukana kwanyengo, kukana kutentha kwambiri, kukana kukanika, njira zomwe zimagwiritsidwa ntchito kwambiri ndi utoto wa ABS +, utoto wopopera wa PP+ ndi PMMA + ABS kutulutsa kawiri. ndondomeko, ndi ndondomeko yovuta ya PMMA. Poyerekeza ndi chiwembu chopopera chopopera, PMMA imatha kuthetsa kupopera mbewu mankhwalawa, kusamala zachilengedwe, kutsika mtengo, ndipo pang'onopang'ono kukhala chiwembu chachikulu.
4, PMMA imagwiritsidwa ntchito pakuwunikira mkati
Kuwala kwamkati kumaphatikizapo magetsi owerengera ndi magetsi ozungulira. Magetsi owerengera ndi gawo la zowunikira mkati mwagalimoto, zomwe nthawi zambiri zimayikidwa padenga lakutsogolo kapena lakumbuyo. Pofuna kupewa kuipitsidwa kwa kuwala, nyali zowerengera nthawi zambiri zimamwaza kuwala, pogwiritsa ntchito njira za matte kapena frosted PMMA kapena PC.
Nyali ya Atmosphere ndi mtundu wowunikira womwe ungapangitse kuti pakhale mpweya wabwino komanso kumapangitsa chidwi chagalimoto. Mizere yowongolera kuwala yomwe imagwiritsidwa ntchito pakuwunikira kozungulira imagawidwa m'mitundu iwiri: yofewa komanso yolimba molingana ndi kapangidwe kake. Mawonekedwe a kalozera wopepuka ndi wovuta, sangathe kupindika, makamaka kudzera mu jekeseni kapena kuumba kwa extrusion, zinthu za PMMA, PC ndi zinthu zina zowonekera.
5, PMMA imagwiritsidwa ntchito kumbuyo kwa galasi lowonera nyumba
Kumbuyo kwa galasi loyang'ana kumbuyo kumafuna kuwala kwakukulu ndi kuwala kwakuda, pomwe kumafuna mphamvu yamphamvu kwambiri, kukana kukanda komanso kukana nyengo. Monga momwe mawonekedwe a galasi lagalasi nthawi zambiri amapindika, zimakhala zosavuta kutulutsa nkhawa, kotero kuti makina akugwira ntchito komanso kulimba kwake kumafunika kukhala okwera kwambiri. Chiwembu ochiritsira ali ABS utsi kupenta, koma ndondomeko kuipitsa kwambiri, ndondomeko zambiri, ntchito PMMA chiwembu akhoza kukwaniritsa kupopera mbewu mankhwalawa kwaulere, zambiri apa ntchito toughened mlingo wa zipangizo PMMA, kukumana mayeso autilaini mu kuyesera dontho ndi zina. ntchito.
Zomwe zili pamwambazi ndikugwiritsa ntchito chizolowezi cha PMMA m'munda wamagalimoto, makamaka okhudzana ndi mawonekedwe kapena mawonekedwe, PMMA imawonjezera mwayi wamagalimoto.
