PC resin umjovo udini
Incazelo emfushane:
Izingxenye ze-PC resin (polycarbonate) zomjovo zisetshenziswa kabanzi emikhiqizweni kagesi, amagobolondo wensimbi kagesi nemikhiqizo kagesi.
Izingxenye ze-PC resin injection molding zisetshenziswa kakhulu kwimikhiqizo kagesi, amagobolondo wensimbi kagesi nemikhiqizo kagesi.
Yini i-PC resin?
Yini i-PC resin (i-polycarbonate) eyaziwa kakhulu njenge-polycarbonate, ngenxa yezakhiwo zayo ezinhle kakhulu zomshini, ezaziwa kakhulu njengeglue-proof glue. I-PC inezici zamandla aphezulu womshini, ibanga lokushisa elibanzi, ukusebenza okuhle kokufakwa kagesi (kepha ukumelana kwe-arc akukashintshi), ukuqina okuhle kobukhulu kanye nokwenza izinto obala.
Umbala wokuqala we-PC awunambala futhi ubala. Imibala ehlukahlukene ebonakalayo, eguquguqukayo ne-opaque nezindawo zokusabalalisa ezikhanyayo zingatholakala ngokungeza i-toner noma i-master batch. Lokhu kwenza kube lula ukwenza imibala yesibani nezinye izingxenye ezinemibala ehlukahlukene.I-PC inemikhiqizo eminingi eguquliwe, njenge-fiber fiber, i-mineral filler, i-chemical flame retardant namanye amaplastiki.
I-PC ine-fluidity empofu nokushisa okuphezulu kokucubungula, ngakho-ke ukucubungulwa kwamamaki amaningi wezinto eziguquliwe kudinga ukwakheka komjovo okhethekile weplastikhi.
Imibala ehlukahlukene ngemuva kokungeza i-toner noma i-masterbatch
Umbala woqobo we-PC resin
Imingcele ebonakalayo ye-PC resin
Ubuningi: 1.18-1.22 g / cm ^ 3 isilinganiso sokukhuliswa komugqa: 3.8 * 10 ^ -5 cm / C izinga lokushisa lokushisa elishisayo: 135 C izinga lokushisa eliphansi - 45 CPC (Polycarbonate) alinambala, libala, limelana nokushisa, limelana nomthelela ilangabi le-BI eligcina ilangabi, futhi linezinto ezinhle zomshini ekushiseni okuvamile kokusebenzisa. Uma kuqhathaniswa ne-polymethyl methacrylate, i-polycarbonate inokuphikisana okuhle komthelela, inkomba ephezulu yokubuyisa nokusebenza okuhle kokucubungula. Ine-UL94 V-2 retardancy yelangabi ngaphandle kwezithasiselo. Ukumelana nokugqoka kwe-polycarbonate kubi. Amanye amadivayisi we-polycarbonate wezicelo ezigqokekayo adinga ukwelashwa okukhethekile kwendawo.
Isebenziselwa ini i-PC resin?
Izinto ze-PC zinokumelana nokushisa okuphezulu, amandla aphezulu, ukuqina okuhle, ukumelana nomthelela, ukuvimbela ilangabi, ububanzi bokushisa obusetshenziswa kakhulu, okungewona ubuthi, ukwenza izinto obala okufika kuma-90%, nezakhiwo ezinhle zomshini ekushiseni okuvamile kokusebenzisa. Ukuzinza okuphezulu, ubukhulu bokuncipha buphansi kakhulu, imvamisa u-0.1% ~ 0.2%. Isetshenziswa kabanzi ku: imishini kagesi, ukukhanya kwe-optical, imishini yezokwelapha, i-tableware, imishini neminye imikhiqizo nemishini.

Uyini inqubo umjovo udini PC resin impahla?
1. Ukwelashwa kweplastiki
I-PC inezinga eliphakeme lokumunca amanzi. Kumele ishiswe kuqala bese yomiswa ngaphambi kokucutshungulwa. I-PC emsulwa yomiswa ngo-120 C. I-PC eguquliwe ivame ukomiswa ngo-110 C amahora angaphezu kwama-4. Isikhathi sokomisa akufanele sidlule amahora ayi-10. Ngokuvamile, indlela yokukhipha umoya emoyeni ingasetshenziswa ukunquma ukuthi ukomisa kwanele.
Inani lezinto ezenziwe kabusha lingafinyelela kuma-20%. Kwezinye izimo, i-100% yezinto ezenziwe kabusha ezingasetshenziswa, futhi isisindo sangempela sincike kuzidingo zekhwalithi zomkhiqizo. Izinto ezenziwe kabusha azikwazi ukuhlanganisa ama-masterbatches ombala ahlukene ngasikhathi sinye, ngaphandle kwalokho izakhiwo zemikhiqizo eqediwe zizolimala kakhulu.
2. Ukukhethwa Injection Molding Machine
Ngenxa yezindleko nezinye izizathu, imikhiqizo ye-PC manje isebenzisa izinto eziguqulwe kakhulu, ikakhulukazi imikhiqizo kagesi, kepha futhi idinga ukukhulisa ukumelana nomlilo. Ngo inqubo ukwakha ilangabi-cishe yizona ezisetshenziswa kabanzi PC kanye neminye imikhiqizo ingxubevange plastic, imfuneko plasticizing uhlelo umjovo udini umshini kuyinto enhle kuhlangana futhi ukugqwala ukumelana. Isikulufa seplastikhi esivamile kunzima ukufeza. Lapho ukhetha futhi uthenga, kufanele kuqiniseke. Kufanele ichazwe kusengaphambili.
3. Idizayini Yesikhunta neSango
Ukushisa okujwayelekile kwesikhunta kungu-80-100 C, kanye nengilazi yefayibha ingu-100-130 C, imikhiqizo emincane ingasetshenziswa isango lenaliti, ukujula kwesango kufanele kube ngu-70% wengxenye ejiyile, amanye amasango anendandatho nonxande.
Uma isango likhudlwana, kungcono ukunciphisa amaphutha abangelwa ukugunda ngokweqile kwepulasitiki. Ukujula komgodi wokukhipha kufanele kube ngaphansi kuka-0.03-0.06mm, futhi umgijimi kufanele abe mfushane futhi azungeze ngangokunokwenzeka. Umthambeko wokudilizwa ngokuvamile cishe ungama-30'-1 degree
4. Ncibilikisa izinga lokushisa
Indlela yokujova umoya ingasetshenziselwa ukunquma ukushisa kokucubungula. Ngokuvamile, izinga lokushisa lokucubungula le-PC lingu-270-320 C, kanti amanye ama-PC alungisiwe noma aphansi we-PC yamaseli angama-230-270 C.
5. Ijubane lokujova
Kuvamile ukusebenzisa isivinini somjovo esisheshayo ukubumba, njengokuvula nokucisha izinto zikagesi. Okuvamile kuhamba kancane ekubonakaliseni ngokushesha.
6, ingcindezi emuva
Ingcindezi yangemuva yebha ye-10 ingancishiswa ngokufanele lapho kungabikho ama-airmark nezithombe zocansi.
7. Isikhathi sokuboshwa
Uma ngabe impahla ihlala ezingeni lokushisa eliphezulu isikhathi eside, izokwehlisa isithunzi, ikhulule i-CO2 bese iphenduka iphuzi. Musa ukuhlanza umgqomo nge-LDPE, i-POM, i-ABS noma i-PA. Sebenzisa i-PS ukuhlanza
I-PC resin ingenye yezinto ezine ezisetshenziswa kakhulu zepulasitiki. IMestech sekunesikhathi isebenzisa amaplastikhi e-PC kanye nama-alloys ayo ekubunjweni komjovo ukukhiqiza izingxenye ezahlukahlukene zepulasitiki. Sizibophezele ekukhonzeni amakhasimende ngokubumba nokujova umjovo walolu hlobo lwemikhiqizo. Uma kunesidingo, sicela uxhumane nathi.
