PMMA ndi chiyani? Kodi PMMA ndi yobwezerezedwanso bwanji?

Kodi PMMA ndi chiyani ndipo chifukwa chiyani ili yoyenera kuyika zodzikongoletsera?

PMMA ndi zinthu za thermoplastic zowonekera kwambiri, zomwe zimalola kuti kuwala kwa 92% kulowerere, kuwonetsa kuwala kowoneka bwino kwa galasi pafupi ndi galasi. Panthawi imodzimodziyo, PMMA imakhala ndi nyengo yabwino yolimbana ndi nyengo ndipo simakonda kukhala achikasu kapena kufota ngakhale itakhala nthawi yaitali ndi kuwala kwa UV. Choncho, zodzoladzola zambiri zapamwamba zimasankha kugwiritsa ntchito mapepala a PMMA kuti apititse patsogolo maonekedwe ndi kukongola kwa mankhwala. Kuphatikiza pa kukopa kwake kowonekera, PMMA imakhalanso yolimbana ndi mankhwala, kuonetsetsa kuti zodzoladzola zakhazikika pa nthawi yosungira.

Ntchito zodziwika bwino zamapaketi a PMMA ndi awa:

Zovala za botolo la seramu: PMMA imatha kuwonetsa mawonekedwe agalasi, omwe amagwirizana ndi kuyika kwa zinthu zapamwamba monga ma seramu.
Zovala zaufa ndi zopaka zodzikongoletsera zonona: Kukana kwa PMMA kumapangitsa kuti zinthu zikhale zotetezeka pakamayenda komanso kugwiritsidwa ntchito tsiku ndi tsiku.
Zipolopolo zowonekera: Zipolopolo zowonekera pazinthu monga milomo ndi maziko, mwachitsanzo, zimasonyeza mtundu wa zomwe zili mkati ndikuwonjezera kumveka kwapamwamba kwa phukusi.

Kodi kuthekera kobwezeretsanso kwa PMMA ndi chiyani?

Pakati pa thermoplastics, PMMA ili ndi mphamvu zobwezeretsanso, makamaka chifukwa kukhazikika kwake kwamankhwala kumalola kuti ikhalebe ndi thupi labwino ngakhale itakonzanso kangapo. Pansipa pali njira zingapo zobwezereranso za PMMA ndi kuthekera kwawo pakugwiritsa ntchito zodzikongoletsera:

Kubwezeretsanso kumakina: PMMA imatha kusinthidwanso mwamakina pophwanya, kusungunula, ndi zina zotere kuti ipangidwenso kukhala ma phukusi atsopano a PMMA kapena zinthu zina. Komabe, PMMA yokonzedwanso mwamakina ikhoza kuchepetsedwa pang'ono, ndipo kubwerezanso muzopaka zodzikongoletsera zapamwamba kumafuna kukonzedwa bwino.

Kubwezeretsanso Chemical: Kupyolera mu ukadaulo wa kuwonongeka kwa mankhwala, PMMA imatha kugawika kukhala monomer MMA (methyl methacrylate), yomwe imatha kupangidwa ndi polymer kuti ipange PMMA yatsopano. njirayi imasunga chiyero chapamwamba ndi kuwonekera kwa PMMA, zomwe zimapangitsa kuti zikhale zoyenera kupanga zopangira zodzoladzola zapamwamba. Kuonjezera apo, kukonzanso mankhwala kumakhala kothandiza kwambiri kwa chilengedwe m'kupita kwanthawi kusiyana ndi kukonzanso makina, koma sikunagwiritsidwe ntchito pamlingo waukulu mu gawo la zodzoladzola chifukwa cha mtengo wake wapamwamba komanso zofunikira zamakono.

Kufunika kwa msika kwazinthu zokhazikika: Ndikukula kwachitetezo cha chilengedwe, mitundu yokongola yambiri yayamba kugwiritsa ntchito zida zobwezerezedwanso za PMMA pakuyika. PMMA yobwezerezedwanso ili pafupi ndi zinthu zomwe sizinachitikepo ndi momwe zimagwirira ntchito ndipo imatha kuchepetsa kugwiritsa ntchito zinthu zopangira, motero kutsitsa mpweya wa carbon. Mitundu yochulukirachulukira ikuphatikiza PMMA yobwezerezedwanso muzopanga zawo, zomwe sizimangokwaniritsa zosowa zokongola, komanso zimagwirizana ndi momwe chitetezo cha chilengedwe chimayendera.

Zoyembekeza zamtsogolo zakukonzanso kwa PMMA muzopakapaka zodzikongoletsera

Ngakhale pali kuthekera kwakukulu kobwezeretsanso kwa PMMA muzopaka zokongola, zovuta zidakalipo. Pakadali pano, ukadaulo wobwezeretsanso PMMA sunafalikire mokwanira, ndipo kukonzanso kwamankhwala ndikokwera mtengo komanso kocheperako. M'tsogolomu, pamene luso lamakono likupita patsogolo komanso makampani ochulukirapo amaika ndalama posungirako zachilengedwe, kukonzanso kwa PMMA kudzakhala kothandiza komanso kofala.

M'nkhaniyi, zopangidwa kukongola akhoza kulimbikitsa chitukuko zisathe za zodzikongoletsera ma CD posankha zobwezerezedwanso PMMA ma CD, optimizing miyeso zachilengedwe mu unyolo kotunga, etc. PMMA sadzakhala zinthu aesthetically zokondweretsa, komanso woimira kusankha kaphatikizidwe chitetezo chilengedwe ndi mafashoni, kotero kuti phukusi lililonse lidzathandiza kuteteza chilengedwe.
