Kuti mukwaniritse zosowa za msika wodzola, makampani kapena ofufuza adzapanga zida zokhala ndi mitundu yosiyanasiyana, mphamvu ndi kusinthasintha ndi zina.
Zida zosiyanasiyana ndizabwino kwa ogula oyendetsa bwino. Koma anthu wamba ambiri nthawi zina amasokonezeka kwambiri, kusokonezedwa pakati pawo pamapeto ndi kusiyana kotani, pamapeto, si zinthu zomwezi.
Anthu ambiri ali ndi mafunso okhudza nthawi yomwe imagwiritsidwa ntchito nthawi zambiri. Chimawoneka ngati galasi kuchokera patali, koma chikuwoneka ngati pulasitiki mukayang'ana kwambiri. Amatchedwa Acrylic, ndi galasi kapena pulasitiki?
Makesi ndi chiyani
Acrylic ndiye dzina lodziwika bwino la nkhaniyi, lomwe limadziwikanso ngati galasi la organic, dzina lachingelezi ndi polymathy methacrylate. Chidule ndi PMMA, dzina lake lathunthu limatchedwa Polymathy Methacryte, zida zake zopangira ndi mankhwala a acrylic.
Nthawi zambiri, timatha kumva dzina la acrylic thonje, acrylic yarn, acrylic nayiloni ndi owonjezera, kuwonjezera pa kugwiritsa ntchito ma shere sheet. Ma sheet a acrylic amapangidwa ndi tinthu tambiri ndi zotumphukira komanso zotayika zina, pomwe ma acrylic ena a ma acrylic amapangidwa ndi ulusi wa acrylic, sakhala gulu lomwelo.
Nthawi zambiri timaona kuti acrylic ndi nkhani yatsopano, koma yapangidwa kwazaka zopitilira zana. Pofika pa 1872, poimba mankhwalawa adapezeka. Mpaka 1920 pepala loyamba la acrylic lidapangidwa mu labotale. Fakitale yomalizidwa yopanga pepala la acrylic mu 1927. Acrylic woyamba amangogwiritsidwa ntchito mu ndege. Kumapeto kwa zaka za zana la 20, ndi kusintha ndi kukhwima kwa ntchito, a acrylic anayamba kugwiritsidwa ntchito kwambiri m'mafakitale ambiri. Ndi chiwonetsero cha kuwala, zopangidwa bwino zopangidwa bwino ndi ma curmer.
Tsopano, acrylic tsopano ndi zinthu zofunika kwambiri kwa mafakitale ambiri, monga mabotolo azodzikongoletsa mabotolo ndi mitsuko, zigawo zamagetsi, magetsi owoneka bwino, maluso owonekera, etc.
Makhalidwe a Acrylic
Acrylic ali ndi kuwonekera kwambiri, masomphenya omveka bwino, amatha kufikira kufalikira kopitilira 92%, Kuwala kowala kwagalasi wamba pamakhala 85%. Itha kufika kuwonekera kwa galasi lamawala, ngakhale kutaya utoto womwe umachulukitsa zokongola za acrylic. Kupatsira ma acrylic kumathandizira kupanga mabotolo a mabotolo a mabotolo a mabotolo a ma botes a acrymelic.
Chifukwa cha zakuthupi zapadera, mphamvu ya acrylic ndiyoposa kambiri kagalasi wamba. Acrylic amatha kufotokozedwa ndi mawu olimba poyerekeza ndi galasi wamba. Zogulitsa zopangidwa ndi zinthu za ma acrylic zimakhala zolimba kwambiri. Zogulitsa zowoneka bwino ndizosalimba chifukwa chomenyedwa. Chifukwa cha mphamvu zake zazikulu, acrylic ndi amodzi mwa zinthu zowoneka bwino kwambiri.
Acrylic amayamba kufewetsa pa 113 ℃, kusungunuka pa 160 ℃. Kutentha kumeneku kumapangitsa kuti tizipindika kwambiri okhala ndi chipilala, kumatha kupangidwa kukhala mawonekedwe aliwonse mosavuta.
Acrylic akutsutsana kwambiri ndikusintha kwa kutentha, chinyezi, acid, alkline, ndikupangitsa kukhala koyenera kwambiri pakugwiritsa ntchito panja.
Ngakhale ma acryli ali ndi zabwino zambiri zotere, koma ali ndi zovuta zina. Choyamba ndi mtengo, acrylic ndiwokwera mtengo kuposagalasi, ndizovuta kusinthanso galasi kwathunthu. Kachiwiri, chifukwa cha kuyamwa kwake, acrylic pomwe amawonekera mwachindunji lawi usungunuka ndipo pamapeto pake amawotchedwa. Kuwotcha aeryli kumatulutsa mimba, kotero ikadulidwa ndi zida zamagetsi, zidzakhala kutentha komanso kosavuta kusokonezeka ndi kugwada.
Chikuwoneka ngati galasi koma ili ngati pulasitiki
Acrylic ali ndi polymer polymer zinthu, zomwe ndi za thermoplastic. Inde, mumawerenga kuti, ndi pulasitiki.
Acrylic amapangidwa ndi monomeric methyl methacrylate polymerization, ndiye kusiyana pakati pa acrylic ndi mapulasti?
Chifukwa cha ma acrylic ndi galasi, zabwino zambiri pagalasi, ndipo zabwino zina zimatha kutengera zolakwa zagalasi.
Zipangizo zowonekera ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale ambiri, ndipo opanga ndi opanga komanso opanga nthawi zambiri amasankha ma polima owonekeratu ngati galasi lachikhalidwe chambiri kapena kusweka mosavuta.
Acrylic amakhala kuti ali ndi zinthu izi zagalasi kapena zida zowonekera, koma silinagawidwe, kotero amatchedwa kutalika.
Njira Zopangira Acrylic
Kupanga ma acrylic kumafanana ndi ma pulasikiki ena, kupatula kuti kutentha kwapadera ndi chothandizira chowonjezera kumatha kusiyanasiyana.
Kupanga Kuumba
Kuponyera mtima kumafunikira nkhungu, masiketi osungunuka amathiridwa mu nkhungu ndikunyamuka kwa maola angapo mpaka atakhala olimba ndipo amatha kuchotsedwa kuchokera ku nkhungu.
Chidutswacho chimasiya nkhunguyo, chimasamutsidwa ku Autoclave, makina apadera omwe amagwiranso chimodzimodzi ndi wophika ndi uvuni. Autoclave amagwiritsa ntchito kutentha ndi kukakamiza kufinya thovu la pulasitiki, kuupereka kwambiri komanso mphamvu zambiri, izi zimatenga maola angapo.
Mukachotsa ma acrylic wowumbidwa kuchokera ku Autoclave, pansi ndi m'mphepete mwa sandpaper yaying'ono kenako ndi gudumu lofewa kuti mutsimikizire mawonekedwe osalala komanso omveka bwino.
Kukula
Zinthu za acrylic pellet zimawonjezeredwa m'makina otalika, omwe amathira zinthu zosaphika mpaka kufika pafupifupi 150 ° C ndikulola kuti zikhale mawonekedwe.
Kenako imadyetsedwa pakati pa makina awiri ogulitsa, ndipo pulasitiki yosungunuka imayatsidwa ndi kupanikizika mu pepala lofanana, kenako pepalalo limakhazikika ndikukhala wolimba.
Tsambalo limadulidwa kwa kukula kwake ndipo lakonzeka kugwiritsa ntchito mutatha kupepera ndi kupukuta. Kuumba Kutayamwa kumatha kukanikiza ma sheet ocheperako ndipo sakupanga mawonekedwe ena kapena ma sheet.
Kuumba jakisoni
Monga zopangidwa zina pulasitiki zamagetsi zamagetsi, jekeseni jakisoni wa acrylic amayikanso ma pellets a acrylic mu makina owuluka, kutentha kwambiri kumapukusa zopangira kukhala phala.
Kenako zida zimalowetsedwa mu mphaka ndipo zimapangidwa kukhala mawonekedwe okhazikika mutayanika ndi mpweya wotentha, kenako ndikukonzekera kugwiritsa ntchito pambuyo popera ndi kupukuta.
Masiku ano, kugwiritsa ntchito a a acryli kumawonjezeka chaka ndi chaka. Ngakhale ma acrylic ndi amodzi mwa zithunzi zakale kwambiri zomwe zikugwiritsidwa ntchito masiku ano, kuwonekera kwake kwa mawonekedwe ndi kukana zakunja kumapangitsa kuti zisankhe zoyambira zamafakitale monga zodzikongoletsera.
