I-polycarbonate monolithic ecacile: ubukhulu, izici, isicelo

Izinto zokwenza izinto ze-polymer zisetshenziselwa kakhulu ekwakhiweni kwezakhiwo ngenhloso ehlukahlukene nangenqubo yokulungisa. Enye yazo i-polycarbonate yeselula, engamelwa ngamaplanethi amabili noma amathathu, phakathi kwezingqimba zaso eside.

Incazelo jikelele

Isakhiwo seselula siqinisekisa amandla omzimba endaweni encane ephansi. Esigabeni esiphambene, le nto ifomu lezinyosi ze-honeycombs zakhiwo ezincantathu noma ezinamacengezi, ngakho-ke igama. I-material eluhlaza yi-polycarbonate e-granular eyakhiwe ngesikhathi sokunciphisa kwama-polymers ama-dihydroxyl compounds ne-carbonic acid. I-polymeri ingokwama-plastiki we-thermosetting futhi inezici eziningi eziyingqayizivele.

Ubukhulu bomugqa nobukhulu beshidi

I-Polycarbonate i-monolithic ebalalayo ingaba nobukhulu obuhlukahlukene nobukhulu obukhulu. Ubuningi buhluka kusuka ku-4 kuya ku-25 mm, kuyilapho inani lezingqimba lingase lifinyelele 6. Ibanga eliphakathi kwezinkani ezinamathekisthi ngobukhulu obuncane buyi-4 mm, le pharamitha ububanzi obuyi-25 mm ngu-20 mm. Ububanzi beshidi bungaba ngu-2.1 no-1.2 m.

Ishidi elincane kunazo zonke lingabhekwa ngendawo engaba ngu-0.7 m, kanti ishidi lama-25 mm alikhuthazwa ukugoba. Ishidi elinomthamo we-20 mm lingakhonjwa endaweni engamamitha amathathu. Ishidi lesine lama-25 mm liyoba nesisindo se-0.8 no-3.4 kg / m ^2, ngokulandelana. Uma unquma ukuthenga i-polycarbonate, ubukhulu beshidi bungase buhluke kulokhu okungenhla, kodwa kulokhu imingcele kufanele ivumelane nomenzi. Ubukhulu bezintamo zizobekwa esimweni sokukhiqiza, kepha ukuphambuka okungavumelekile kwalolu pharamitha akuqinisekisiwe.

Izici zobuchwepheshe: izinga lokushisa lokushisa

Ku-assortment enkulu namhlanje i- polycarbonate e-monolithic. Umkhiqizi u-Prisma-Plastik unikeza impahla enokumelana nokumelana nezimo ezingavumelekile zemvelo. Ukusetshenziswa komshini wokushisa kuxhomeke kulophawu, ukuhambisana nobuchwepheshe bokukhiqiza kanye nekhwalithi yezinto zokusetshenziswa. Cishe zonke izinhlobo zamapaneli, le nkhomba ihluka kusuka -40 kuya +130 ° C. Uma uthengiswa ungathola i-polycarbonate monolithic ebonakalayo, ekwazi ukushisa okushisa kakhulu kuya ku- -100 ° C, kanti isakhiwo sezinto ngeke siphulwe.

Lapho ukupholisa nokushisa, izilinganiso ezilinganayo zizoshintsha. Ukwandiswa okuvunyelwe kwe-polycarbonate yamaselula akumele kudlule u-3 mm nge-1 m, lokhu akusebenzi nje kuphela ububanzi, kodwa nobude. I-Polycarbonate transparent monolithic ibonakala ngokunyuka okukhulu okushisayo, ngakho-ke ekufakweni kwayo kuyadingeka ukushiya izikhala ezihambisanayo.

Ukumelana kwama-Chemical

Uma iphaneli lihloswe ukuthi lisetshenziselwe ukuqedela, kufanele kukhunjulwe ukuthi lingabonakaliswa ezinhlobonhlobo zezinto ezilimazayo. I-Polycarbonate imelana kakhulu namakhemikhali namakhemikhali. Noma kunjalo, kusadingeki ukuthi kuvunyelwe ukuxhumana kwe-polycarbonate ngezinto ezifana nalezi:

• I-PVC emaplastiki;
• Izingxube zesimiso;
• Izinambuzane ze-Aerosol;
• Ukukhonjwa;
• Ama-sealants asekelwe ku-ammonia;
• Izithako ezinamandla;
• Izinto ezisuselwa ku-acetic acid;
• Ama-halogen nama-solvents;
• Izixazululo ze-methyl utshwala.

I-Polycarbonate i-monolithic ebonakalayo inokumelana nokuphikisana kwamakhemikhali okulandelayo:

• Izixazululo zosawoti nge-reaction neutral acid;
• Amaminerali amaminerali agxile;
• Ukuphuza utshwala;
• Iningi lalezi zinxube kanye nama-agent ehlisa.

Kodwa-ke, uma kwenzeka izixazululo zotshwala, kubalulekile ukukhipha umphumela we-methanol kule ndaba. Uma ufaka ama-polycarbonate, ama-silicone sealants kanye ne-EPDM-izici zokufaka uphawu zokufaka uphawu olwenziwe ngale njongo kufanele zisetshenziswe.

Amandla kagesi

I-Polycarbonate, okuyizinhlamvu zamashidi ezishiwo ngenhla, inezinamandla eziphezulu zamandla, le nto ikwazi ukubhekana nemithwalo ebalulekile. Kodwa uma ubuso buvezwa ekuthunjweni, uxhumane nezinhlayiya ezinhle ngohlobo lweshlabathi kungabangela umonakalo ku-substrate. Kulesi simo, ungase uhlangabezane nokuthi indaba izobe ifakwe emanxebeni ngemuva kwesikhathi esithile, njengamacala lapho ehlangana nezinto ezimbi. I-monolithic polycarbonate, intengo ngayinye ehlukahlukene ehlukahluka kuye ngokuthi ubukhulu bungakanani, inamandla amaningana, ayoxhomeka kwisakhiwo kanye nomkhiqizo wendaba.

Ngemuva kokuhlolwa, imiphumela elandelayo itholwe. Amandla okuqina angama-MPa angu-60, kanti ukuguquguquka okuhambisanayo ekufinyeleleni amandla okugcina kungu-6%. Lezi zinto nazo zinamandla okuthela, okuyi-MPa engu-70. Uhlobo olunesihlobo emkhakheni wokuvunwa ngu-100%. Amandla okuthinta okushiwo yi-65 kJ / mm, kepha ngokuqondene nokuguquguquka, lilingana no-35 kJ / mm ² . Umkhiqizi uqinisekisa ukuthi izici zokusebenza zale ndaba zizogcinwa iminyaka emihlanu, lokhu kuyiqiniso uma amashidi efakwe kahle.

Ukuphikisana ne-ultraviolet

Iphepha le-polycarbonate elibonakalayo elingu-monolithic elibonakalayo likwazi ukuqinisekisa ukuvikelwa okunokwethenjelwa emisebeni e-UV-range. Ukuze uzuze lo mphumela, ukugqoka okuqinisekisiwe okusetshenzisiwe kusetshenziselwa phezulu nge-coextrusion ngesikhathi sokukhiqiza. Lobuchwepheshe buhlinzeka ngempilo encane yokusebenza yendaba iminyaka eyishumi.

Inqola yengubo yokuzivikela ayikho ngenxa yokuthi i-polymer ixhunyiwe kwi-substrate. Uma ufaka ishidi, hlola izimpawu bese ulifaka ngendlela efanele. Isigqoko sokuvikelwa emisebeni yelanga kufanele senziwe ngaphandle. Ukudluliselwa kokukhanya kuxhomeke kumbala, futhi uma kwenzeka kumashidi ambala, leli xabiso lihluka phakathi kuka-83 no-90%. Uma ivela kumapaneli ezinemibala, amandla abo okudlulisa ukukhanya akudluli ku-65%, kuyilapho i-polycarbonate ihlakazeka kahle.

Izakhiwo zokushisa okushisa

I-polycarbonate ebonakalayo yezitshalo zokugcina izithombo kufanele ibe nezindawo zokufaka ukushisa. I-coefficient yokudlulisa ukufudumala, ebonakala ngezakhiwo zokushisa ukushisa, kuxhomeke kwisakhiwo nokuqina kweshidi. Leli pharamitha lihluka kusuka ku-4.1 W / (m² · K), okuyiqiniso kwekhasi le-4 mm, kufika ku-1.4 W / (m² · K) elilodwa lekhasi le-32 mm. I-polycarbonate yeselula iyinhlangano evumelana kakhulu lapho kuhlanganiswa khona izimfanelo eziphezulu zokushisa okushisa nokucaca. Yingakho kuvame ukusetshenziswa ekwakhiweni kwezindawo zokugcina izithombo.

Ububanzi bokusetshenziswa

Ngenxa yokusebenza okuningi, i-polycarbonate isetshenziswa namuhla ezindaweni eziningi zokukhiqiza izimboni. Awukwazi ukuthola imboni lapho le polymer ingasetshenziselwa khona. Ukwakhiwa, isetshenziselwa ukugqoka, lapho kuvezwa khona obala kanye namandla. Izindwangu ezivela epulasitiki yamaselula ziyakwazi ukumelana nemithelela nemithwalo yomoya. Emigwaqweni ungathola izakhiwo eziningi ezisebenzela ukuphepha kwezimoto, phakathi kwazo kufanele ziphawulwe:

• Indawo yokuhlala yokuhamba ngezinyawo;
• Izihlangu zokuzivikela;
• Ukuthutha komphakathi kuyeka;
• Amalensi okukhanyisa amadivaysi;
• Izimpawu zomgwaqo nezimpawu.

Le ipulasitiki yindlela yokubonakalisa iphupho lama-agrarians mayelana nokubonakala okubonakalayo, okuqinile nokukhanya. It isetshenziselwa ilungiselelo zokugcina izithombo kanye zokugcina izithombo. I-Polycarbonate yiyona nto efanelekayo yokudala imikhiqizo ehlukahlukene yokubonisa ibhizinisi nemidlalo. Kusuka kuwo izigqoko zokuzivikela, futhi ngezizinda ze-hockey zepulasitiki ye-monolithic, ungathola iziketi ezivikelayo.

Omunye imboni yimboni yokudla. Ukungena kwamakhemikhali kukuvumela ukuthi wenze ama-polycarbonate cutlery kanye nezitsha ezingenakunyakaziswa. I-monolithic polycarbonate, intengo ngayinye eyamukelekayo, isetshenziswa namhlanje emithi yokwenza imikhumbi, amacala, amalunga okufakelwa namazinyo. Omunye akakwazi ukusiza kodwa uqaphele insimu ye-electronics kanye nembonini yamakhemikhali, lapho i-polycarbonate isetshenziselwa khona njengento engenzi lutho njengamanje.

Izindleko

I-Polycarbonate monolithic e-2-mm ebonakalayo izobiza ama-ruble angu-3900. Ngeshidi, ubukhulu bawo obuyi-2.05 x 3.05 m. Intengo izohluka ngokuya ngobukhulu. Ngakho-ke, ku-0,6-mm ishidi kubalulekile ukukhokha ama-ruble angu-650, ngakho-ke usayizi uyokwenza u-1,25 x 2,05 m. Uma ubukhulu bungalingana no-12 mm, izindleko zizokwenza u-23400 rbl. Ngeshidi elinama-2.05 x 3.05 m.
