　　Kwimeko enkulu yezinto ezinkulu zokwenziwa, bambalwa abaye bafumana ubundlobongela obukhulu kwaye baguqukayo kwi-Acrylic iphepha, elibizwa ngokuba yiPolymethyl metacrylate, okanye i-PMMA. Kuluntu ngokubanzi, kusoloko kudibana phantsi kwamagama orhwebo afana nePlexiglas, i-Lucite, okanye i-Perpex, kodwa ezi ntlobo zibonisa i-polymer engafaniyo ehamba nenye indlela ephezulu kwiglasi enkulu. Uhambo lwe-acrylic ukusuka kwi-labhoratri ye-labhoratri yezellowel indawo efakwe kwi-Netland iqhutywa yiseti yezinto ezibonakalayo zepropathi eyahlukileyo, ehambelana nokusetyenziswa kwengqondo. Ukuqonda ukuba le phepha le-Acrylic ifuna ukuyenza impindezelo ngaphaya kwengca yeglasi yayo yokuxabisa iSayensi kunye nezibonelelo ezenziwayo ezenza ukuba zibe lukhetho olungenakuphikwa kweenjineli, oovimba, amagcisa, kunye nenkxaso-qhayiya. Intliziyo yakhe, i-Acrylic yi-thermoplastic, intsingiselo ithe ithambile kwaye inesibindi kwaye inzima ekuphoxekeni, umlinganiswa ovula amagqabantshintshi avela kwimilinganiselo yokugoba egudileyo.

　　Imvelaphi ye-PMMA inomdla njengamatyotyombe. Ngelixa inkqubo yemichiza yokwenza i-Acrylid Acid yafunyanwa phakathi kwenkulungwane ye-19, yayingekadalwanga kwinkulungwane yama-20 apho umbatha wafumana ubizo lwayo lokwenene. Ngeminyaka yee-1930s, oochwephesha kwi-ricriant guc0hm kunye ne-haas eJamani babephuhlisa iglasi yokhuseleko ukuze basebenzise iimoto. Injongo yabo yayikukudala izinto ezenzayo ezingenakutshabalalisa ingozi kwimpembelelo. Ngeli xesha lophando, bangenza ngempumelelo i-methyl methyl metacrylate kwiphepha elicacileyo, eliqinileyo, kwaye ke, iGradi ye-Acrylic esebenzayo yazalwa. Isicelo sayo sokuqala, nangona kunjalo, sasingekakwifestile yemoto kodwa kwi-cockpings yenqwelo moya yasemkhosini ngexesha leMfazwe yesibini yeHlabathi. Ukucaca komzimba okhethekileyo, kudityaniswe nobunzima bayo kwaye kuxhathise ukuphatha iinqwelomoya, ukubonelela ngeenqwelomoya abanamalungelo ngempatho ebalulekileyo, ukuhambisa ukubonakala okuphezulu kunye nokukhusela. Olu xinzelelo lwexeshana elibalulekileyo lokusetyenziswa lubonakalise i-mettle yempahla kwaye ivule indlela yokuqhushumba ukuba ibe ngumthengi woxolo kunye neemarike zemizi mveliso emva kwemfazwe, apho yaqala khona ukutshintsha iglasi kwizibane zomsila ze-autorium.

　　Mhlawumbi eyona nto iphambili kwipropathi ye-acrylic iscocical yayo engapheliyo. Kwizicelo ezininzi, ayisiyondlela nje enye kwiglasi kodwa iphuculo olubonakalayo. I-acrylic esemgangathweni idlulisele ukuya kuthi ga kwi-92% yokukhanya okubonakalayo, umzobo ongaphezulu kweyona ntlobo kweglasi yeglasi. Olu hlaselo lukhanyiso oluphezulu ludibene nococeko olukhethekileyo, okuthetha ukuba alunalo uluhlaza okanye lube ne-ting tint idla ngokunxulunyaniswa nemiphetho yeephaneli zeglasi. Lo mgangatho wekristale-ocacileyo usenza ukuba kuthathelwe ingqalelo apho, umbono ongafunekiyo yi-paramount, okanye iifestile ezikhuselayo kwi-Aquarium ye-HOCKEY, okanye i-genoramic ye-rions emele ukonakaza amava okwenza iindwendwe. Ngaphaya koko, izenzo ze-acrylic njengecebo lendalo lokukhanya kwendalo i-ultraviolet. Ngelixa ivumela ukukhanya okubonakalayo ukuba kudlule ekungeneni, kubhloka inxenye enkulu ye-UV yelanga eyenzakalisayo. Le ndawo ibaluleke kakhulu ekukhuseleni ubugcisa obuxabisekileyo kwiimyuziyam, ukuthintela amalaphu kunye neelaphu kumagumbi aphantsi kwelanga ekupheliseni, kunye nokuqinisekisa uzinzo lwexesha elide lwezixhobo ezibonisiweyo emva kwayo.

　　Ngaphandle kokusebenza kwalo okubonakalayo, izibonelelo zomzimba ze-acrylic zininzi kwaye zinempembelelo. Enye yezona zinto zibalulekileyo zinobunzima bayo; Iplastiki ye-Acrylic inobunzima obungaphezulu kwesiqingatha njengesiqwengana seglasi efanayo. Olu ncitshiso lokukhululeka kubunzima buneziphumo ezinzulu zezinto, inkxaso yolwakhiwo, kunye nokufakelwa kokufakwa. Ulwakhiwo lwezinto eziluluyikayo ziyila izibane ezikhulu okanye iindonga zekhehla, ukusetyenziswa kwe-acrylic kunokwenza lula isikhokelo sokuxhasa kunye nokunciphisa imithwalo yokwakha. Umphathi wentengiso ofaka ityala elikhulu okanye uphawu, uhlobo olukhanyayo lwezinto ezenza uphatha kunye nokuphakamisa umsebenzi omncinci omninzi. Oku kukhanya kuxhaswe bubuchule obuyibonakala inkangeleko yempahla. I-Acrylic ichaphazela kakhulu ifuthe elixhaphakileyo, ukuba liqinile amaxesha ali-10 ukuya kweli-17 eyomeleleyo kuneglasi yefestile eqhelekileyo malunga neempembelelo ezibukhali. Oku komelene kuyayenza ukuba ibe yindawo yeNkulumbuso yokhuseleko kwi-egreys kwindawo efana nezikolo, iibhasi, iintolongo, umngcipheko wokuqalisa kufuneka uncitshiswe. Xa i-Acrylic iphumele phantsi kwamandla agqithisileyo, kukwenze okukhuselekileyo kuneglasi. Endaweni yokutyibilika kubandakanywa kwi-shards engaphezulu, i-shagger-njenge-shards, ihlala iqhekeza ibe ngamaqhekeza amakhulu, anqabileyo, ukunciphisa ingozi yokulimala.

　　Ukugxila kwephepha le-acrylic akupheleli kwifom yayo ecacileyo ye-crystal. Lo mbandela uyafumaneka kwi-palette engapheliyo yemibala, i-OPACE, kunye noThengisa, olwandisa uyilo lwayo. Inokufumaneka kwi-opaque, i-hies esebenzayo ilungele imiqondiso yale mihla kunye neepaneli zokuhombisa, iindidi eziThembeleyo ezikhanyayo ezithambileyo kwizicelo zokukhanyisa, kwaye zize ziqwalasele ezona zibalulekileyo. Iindawo ezigciniweyo, ezifana ne-frissed, ezixhonywe, okanye iipateni ezirhangqiweyo, zinokusetyenziselwa ukubonelela ngemfihlo, zisasaze ngokulinganayo, okanye zongeza ubume obuthile. Olu tshintsho luthetha ukuba i-Acrylic ininzi kakhulu ekhaya kwivenkile ethengisa i-terital yefashoni njengoko ikwindawo yesayensi. Ubunjani bayo njenge-thermoplastic iphambili kwizinto zayo zokusebenza. Xa ifudumele kubushushu beqondo lokwakha (ngokwesiqhelo phakathi kwe-150-160 ° 2 ° 2 Le nkqubo, eyaziwa njenge-therformang, isetyenziselwa ukwenza yonke into ukusuka kwi-Lattub, i-Battubs ehleliweyo kunye neendawo zokuhlambela ezifumaneka kwi-aerodnamic kwizithuthi kunye neziboniso zenkcubeko ezisetyenziswa kwimiboniso yorhwebo. Obu buchule bokubelwa buvumela lula ukuba ivumela inqanaba lenkululeko yoyilo elingenakwenzeka nje ngeglasi.

　　Kwabo banqwenela ukusebenza ne-Acrylic, ukusebenza kwayo yinto ephambili. Inokuba ngoomatshini kwaye kusetyenziswa izixhobo zokusetyenziswa kwezixhobo ezihlala zifumaneka kwiindibano zocweyo ezixhotyiswe kakuhle. Ukushokoxeka komgca othe tye, isixhobo esilula sokufumana amanqaku sinokusetyenziselwa ukuqhushumba umgca onzulu kumphezulu, emva kwephepha elinokutsalwa ngokucocekileyo ecaleni kwenqaku. Kwi-curves ezintsonkothileyo kunye neemilo, ii-jigsaws, ibhendi ye-band, okanye iiross ze-CNS ezine-Blades zinokuvelisa ukuncitshiswa okuqinisekileyo. Ukuqhuba imingxunya kuya ngqo, nangona kufuna ukhathalelo ukunqanda ukuvelisa ubushushu obugqithisileyo, enokunyibilika iplasitiki kwaye ibangele i-chip okanye iqhekeza; Sebenzisa i-bits ebukhali kunye nesantya esicothayo sibalulekile. Ubugcisa bokwenyani bokusebenza nge-Acrylic, nangona kunjalo, bahlala belele kwinkqubo yokujoyina. Ngokungafaniyo neglasi, eya kuthi ifuna ukubandakanywa kwezinto, iziqwenga ze-acrylic zinokwenziwa ngokudibeneyo ngokusebenzisa i-crances ekhethekileyo. Esi sinyibilikisi somanzi sisetyenziswa kwimiphetho ye-acrylic ukuba idityaniswe, apho inyibilikisa okwethutyana imixokelelwane yePolymer. Xa la maqhekeza amabini acinezelwe kunye, la makhonkco lathatyatha kwaye aphinde aqine njengoko i-Solvent ivela, ukudala ibhondini edla ngokuqina njengezixhobo zabazali kwaye zibonakala ngokuchanekileyo. Oku kuvumela ukudalwa kweebhokisi ezingenamthungo, imiboniso, kunye ne-aquariums enembonakalo engenasipho, inkangeleko.

　　Ngaphandle kwamandla amakhulu, kubalulekile ukuba uqonde ukusikelwa umda kwe-ACRYCLE ukuyisebenzisa ngokufanelekileyo. Olona phepha luqhelekileyo luphawulekayo kukuchaphazeleka kwayo ukukrwada. Ngelixa ukunganyangeki kwempembelelo kukuphakama kwayo, ubunzima bayo bungaphantsi kunelo yeglasi, kokwenza ukuba kubekho ngakumbi kwizinto ezintle ezivela e-Abrasion. Nangona kunjalo, lo mbandela uhlala uhleli ngaphezulu. I-scract scractches ezincinci zihlala ziphindwe rhoqo usebenzisa i-politing yeplastiki okanye i-abrarive ethambileyo njengezinyo. Kwizicelo apho ukunganyangeki kwe-scaratch kubalulekile, njenge-tabletop okanye isithintelo esicociweyo, abavelisi banikezela amabakala e-arasion-unganyangeki i-atrical (i-ARD) yamabakala e-Acrylic ephucula kakhulu ekuqhubeni. Olunye ukuqwalaselwa yindlela yalo yokuphendula, ubushushu bendawo. Ngelixa u-Acrylic iyonke iyonke inokuthi ibe nenxaxheba kakhulu kwaye ingathanda ukwahluka kobushushu kwiseto engaphandle, akufuneki isetyenziswe kufutshane nelangatye elivulekileyo okanye umthombo wobushushu obuphezulu, njengoko inokuthambisa, okanye inyibilike, okanye inyibilike, okanye inyibilike. Ireyithi yayo yokwandiswa kwethermal ikwaphezulu kunelo yeglasi, intsingiselo yentsingiselo kufuneka ivumele inani elincinci lentshukumo kwi-Fraing ukunqanda uxinzelelo ekwakheni kwaye lubangele ukuba lube noxinzelelo.

　　Ukuphunyezwa kwexesha elide kwe-acrylic, ngakumbi ngaphandle, yiTestamente yokuzinza kwayo. Iphepha eliphezulu le-ACRRYCLICIl le-acrylic lixhaphake kakhulu kwiziphumo zenyama nemozulu. Ayityheli okanye ibe brittle ngokuhamba kwexesha, indlela eqhelekileyo yokusilela kwezinye iiplastiki ezininzi. Olu gama lukhethekileyo kukuba nenxaxheba yi-Acrylic yeyona nto iphantsi kwezinto ezisemgangathweni, iikheno zoyilo, kunye nezinto ezikhanyayo; Igcina ucango lwayo kunye namandla eshumi leminyaka okanye ngaphezulu ngolondolozo oluncinci. Ukucoca i-acrylic ngumsebenzi olulula, kodwa kufuneka kwenziwe ngokuchanekileyo ukuba ugcine ubuhle bayo. Indlela ecetyiswayo kukucoca umphezulu ngamanzi ukuze ususe nayiphi na i-Grit egudileyo, emva koko uyisule kancinci ngendwangu ethambileyo, engenazintlukwanga okanye isiponji esithambileyo sesona kwisisombululo esisezantsi okanye isicoci. Abacoci abonwabisayo, iimveliso ezisekwe kwi-ammonia ezifana newindows zicocekile, okanye iitawuli zephepha elirhabaxa kufuneka zithintelwe ngokungqongqo, njengoko ziya kuthi zizenzele inethiwekhi ye-scratched engaphaya kwexesha.

　　Ukuqukumbela, ukubuza "yiphi i-acrylic?" kukubuza malunga nesona sixhobo siphumelele size sibe siphumelele kwizinto zanamhlanje. Ingaphezulu nje kweglasi; Kungumlinganiso osebenza kakhulu obonelela ngokudibeneyo nokunyanzelekileyo kokucaca okuqinisekileyo, amandla olwakhiwo, lula lula, kunye nokudalwa okungathethekiyo. Ukusuka kwindima yayo ebalulekileyo kwimbali yangoku imbali yangoku njengesixhobo sokwakha, intengiso, uyilo, itekhnoloji, i-Acrylic (PMMA) ifumene indawo yayo ngokungaguqukiyo. Ngokuqonda iprofayili yayo epheleleyo - Amandla Ayo, Ubuthathaka bayo, kunye neenkqubo zayo ezichanekileyo, abakhi, kunye nabasenzi bobuhle kakhulu ukwenza izakhiwo ezikhuselekileyo, kwaye izisombululo ezihle kakhulu. Yinto engavumelani nje kuphela ukukhanya kodwa nayo iyayila, kwaye ikhokele ngokukhuselekileyo ngaphakathi kwezakhiwo ezihlala zihleli.
