Polycarbonate monolithic ngaphaya: ubungakanani, iimpawu, isicelo

izinto Polymeric ngoku afumaneka ngokubanzi ukwakhiwa kwezakhiwo ngeenjongo ezahlukeneyo kunye ikhondo ukulungiswa. Enye yezi polycarbonate leyo angamelwa ligqiza emibini okanye emithathu-sixhobo sekhombuya esinee, apho amalungiselelo phakathi kweengqimba stiffeners longitudinal.

incazelo jikelele

Ubume enemingxuma uqinisekisa amandla ngoomatshini kwi ubunzima encinane ethile. Kwicandelo cross, le nto na uhlobo honeycombs shape elingunxantathu okanye eziziingxande, kungoko igama. Njengoko izinto ekrwada kuphuma polycarbonate granular, iipholima lisekwa iikhompawundi amafu dihydroxy kunye asidi. Polymer inxulumene iiplastiki thermosetting kwaye iimpawu ezininzi ezizodwa.

zobukhulu yomgama kunye ubunzima ezithile wetshati

Polycarbonate monolithic ngaphaya kunokuba ngobukhulu, nokundileka ethile. Ebubanzini yahluka ukusuka-4 ukuya kwi-25 mm, ngelixa inani lamanqanaba zinokufikelela 6. Umgama phakathi ezimbanjeni kufuphi Ebubanzini izinto ezincinci ngu-4 mm, le parameter-25 ubukhulu mm iya kuba yi-20 mm. Ububanzi sheet inokuba kulingana 2.1 no-1.2 m.

Ebubanzini zincinane sheet ungagotywa kunye oyi-0.7 m, lo gama i-answer sheet olubalulekileyo kodwa enomva 25 mm. Iphepha le ubukhulu ka-20 mm ungagotywa endaweni engaba iphepha-3 m. 4 no-25 mm kuya kuba ubunzima leyo ilingana no 0.8 no 3.4 kg / m ^2, ngokulandelelana. Ukuba ugqiba ukuba uthenge ubungakanani sheet polycarbonate inokuba nomahluko ukusuka ngentla, kodwa kulo mzekelo, imida ukuba kuvunyelwane umvelisi. Ububanzi iimbambo ziya kumiselwa ezingeni lokuvelisa, kodwa ecaleni eliphezulu avumelekile lingakulungele kule parameter.

Ukucacisa: lobushushu zokusebenza

Xa uluhlu enkulu unikela yayo polycarbonate esiqinileyo. Nomakhi "Prism-Plastic" izinto inika ukuxhathisa kakhulu iimeko engentle yokusingqongileyo. Iqondo lobushushu iindlela yokusetyenziswa zixhomekeke kwibanga, ukuthobela kunye nomgangatho imveliso izinto ekrwada technology. Phantse zonke iintlobo panels, eli nani ziyohluka ukusuka -40 ukuya +130 ° C. Sales ukwazi ukuhlangabezana polycarbonate transparent monolithic, ezinako yenzelwa i obushushu asezantsi kakhulu ukuya -100 ° C, akayi kuba eyaphukileyo isakhiwo eziphathekayo.

Ukupholisa kunye zokufudumeza utshintsho nemilinganiselo yomgama ziya kwenzeka. Kuvumelekile ukwanda polycarbonate mayingagqithi 3 mm nganye-1 m, oko nje kuphela ububanzi kodwa ubude. Polycarbonate monolithic ngaphaya ephawuleka yokwanda thermal ezibalulekileyo, ngoko umele ushiye kugqitywe ezaneleyo xa ufaka kuyo.

ukumelana Chemical

Ukuba ubukhulu bendawo yolawulo iza kusetyenziswa uhombiso, kufuneka kukhunjulwe ukuba lungakhuseleki kwi ezahlukeneyo izinto yentshabalalo. Polycarbonate linamandla kakhulu ukuba iikhemikhali kunye nemixube. Noko ke, ayikhuthazwa tu into yokuba musa ukudibanisa izinto polycarbonate ezifana:

• PVC plasticized;
• umxube isamente;
• zinambuzane zetoti;
• eziphathekayo;
• Sealants esekelwe ammonia;
• izicoci ezinamandla;
• arhente ngokusekelwe acetic acid;
• izinyibilikisi enuka kamnandi, kwaye halogen;
• izisombululo ze methyl utywala.

polycarbonate transparent monolithic has a uzinzo yemichiza eziphakamileyo ezi zinto zilandelayo:

• izisombululo saline asabela cala asidi;
• acid ezimbiwa kanzulu;
• izisombululo utshwala;
• iintlobo ezininzi oxidizing nokunciphisa arhente.

Nangona kunjalo, kwimeko kwezisombululo utywala, kubalulekile ukuphepha utyhileko izinto methanol. Xa ufaka le polycarbonate kufuneka zisetyenziswe sealants abicah ize iphuhliswe ukwenzela ngamasuntswana uphawu uhlobo EPDM kunye analogue yayo.

amandla mechanical

ubungakanani Iphepha Polycarbonate ezithe ekhankanywe ngasentla has a amandla aphezulu ngomatshini, a enako .eyona imithwalo ezibalulekileyo. Kodwa ukuba wayo phantsi lingonakali, ukuqhagamshelana amasuntswana omhle uhlobo kwentlabathi kunokubangela umonakalo lesiseko. Kulo mzekelo, ungenza ayamkele into yokuba izinto emva kwexesha elithile kuya kukugubungela imikrwelo, ngokuphathelele amatyala ukunxibelelana izinto rough. polycarbonate Monolithic, ixabiso uxwebhu ngamnye apho kuyahlukana nedlela Ebubanzini, kukho amandla athile ngomatshini, nto leyo eza kuxhomekeka kubume kunye kwibanga eziphathekayo.

Emva kovavanyo wakwazi ukufumana ezi ziphumo zilandelayo. uqine kwi lekhefu yaba 60 MPA, kanti xa deformation relative uqine yi-6%. Le nto iye kwakhona aqine yona 70 MPA. Le abahluza kwindawo hoxa yi-100%. Kobulembu zokufunda 65 kJ / mm, kodwa ngokuphathelele deformation, akukho 35 kJ / mm ^2. Ziziqinisekiso kumenzi iimpawu ukusebenza zinto ziya kugcinwa iminyaka emi-5, oku kuyinyaniso, ukuba iimakhishithi zifakelwe kakuhle.

UV ukumelana

Iphepha Polycarbonate oluselubala monolithic nako ukuqinisekisa ukhuseleko ngokuchasene radiation kwi UV-kuluhlu. Ukuphumeza oku isiphumo, kwinkqubo lokuvelisa phezu komhlaba indlela coextrusion olusetyenziswa ukutyabeka okhethekileyo ozinzileyo. Le iteknoloji inika ubuncinane ubomi yokusebenza umbandela kangangeminyaka eli-10.

Delamination ye ukutyabeka yokhuselo akwenzeki ngenxa yokuba Polymer ihlanganiswa kwi siseko. Xa ufaka le kuxwebhu kufuneka ahlolwe zokumakisha uyifake ngokuchanekileyo. Ukugubungela ukukhuselwa kumaza elanga kufuneka sibhalwe ngaphandle. transmission Ukukhanya kuxhomekeke umbala, yaye kwimeko sheets ezinemibala, eli nani ziyohluka ukusuka 83 ukuya 90%. Ukuba sithetha le bar anemibala, ngoko transmission ukukhanya yabo ayidluli 65%, lo gama polycarbonate yi Uchithachitha kakhulu ukukhanya.

Iipropati ukwahlukanisa thermal

polycarbonate neselubala zokugcina kufuneka iipropati zokwambathisa ezikhoyo. Le lomlingani transfer ubushushu, luphawulwa iipropati ubushushu-zokwambathisa, kuxhomekeke isakhiwo kunye ubukhulu sheet. Le parameter uyahluka 4.1 W / (m² · K), nto leyo lokwenyaniso yemigca-4 mm, ukuya ku 1.4 W / (m² · K) --mm 32. Polycarbonate - izinto ifanelekileyo apho kuyimfuneko indibanisela iimpawu ubushushu ophezulu thermal elubala. Kungenxa yoko le nto idla ngokusetyenziswa xa kusakhiwa zokugcina.

Ububanzi bokusebenzisa

ngenxa yokusebenza By, polycarbonate lisetyenziswa namhlanje kwiindawo ezininzi kwemveliso yoshishino. Awukwazi ukufumana eli candelo, apho Polymer ayizange isetyenziswe. Xa ukwakhiwa isetyenziselwa Injengokubengezela, ekufuneka elubala kunye namandla. Uphahla eyenziwe ngeplastiki yeselula, nako ukumelana izipha nomthwalo nomoya. Endleleni uyakwazi ukufumana izibonelelo ezininzi asetyenziswa ukhuseleko, bonisa phakathi kwabo:

• indawo yokuwela yabahamba;
• izihlangu;
• zokumisa izithuthi zikawonke-wonke;
• lens izixhobo kukhanyise;
• Iimpawu zendlela nemiqondiso.

Le kokulungisa ungumthombo amafama iphupha iimathiriyeli ngaphaya, bomelele ezilula. Isetyenziswa zonke zokugcina kunye zokugcina. Polycarbonate - ngumnqweno ngokudala ezahlukeneyo iimveliso ze show zoshishino kunye nemidlalo eziphathekayo. Ngenxa enokuba kubhaliwe wenza iminqwazi, ihoki kunye ngezizathu zeplastiki ngakumbi ingafumaneka ezigudle olukhuselayo.

Enye candelo yokudla. inertness Chemical ikuvumela ukuvelisa polycarbonate izixhobo kunye izitya ayinakutshintshwa. polycarbonate Monolithic, ixabiso iphepha ngalinye kwamkelekile kakhulu, kwaye esetyenziswa namhlanje iyeza ekwenzeni izitya, izakhiwo, amalungu iisoyi kunye zitho amazinyo. Kufuneka kuqatshelwe ummandla elektroniki kunye namashishini imichiza, apho polycarbonate isetyenziswa njenge material engeyoyangeli ukuqhuba yangoku.

iindleko

Polycarbonate monolithic 2-mm ngaphaya iya kuxabisa 3900 engange. Iphepha ngalinye, eligqala 2,05 x 3,05 yeemitha. Ixabiso iya kwahluka ngokuxhomekeke ubukhulu. Ngoko ke, ngokuba yemigca-0.6 mm iya kuhlawula 650 engange., Kwathiwa, ubukhulu iya kuba 1.25 x 2,05 m. Xa ubukhulu ilingana-12 mm, iindleko 23400 bagcobe. ukuba sheet ogama bungu 2,05 x 3,05 m.
