Kodi PC resin ndi chiyani?
Kodi PC resin (polycarbonate) imadziwika bwanji kuti polycarbonate, chifukwa cha makina ake abwino, omwe amadziwika kuti zomatira za bullet-proof. PC imakhala ndi mphamvu zamagetsi, kutentha kwakukulu, magwiridwe antchito abwino amagetsi (koma kukana kwa arc sikusintha), kukhazikika bwino komanso kuwonekera poyera.
Mtundu wapachiyambi wa PC ulibe mtundu komanso wowonekera. Mitundu yosiyanasiyana yowonekera, yopepuka komanso yowoneka bwino imatha kupezeka powonjezera toner kapena batch master. Izi zimapangitsa kukhala kosavuta kupanga mithunzi ya nyali ndi magawo ena okhala ndi mitundu yosiyanasiyana.PC ilinso ndi zinthu zambiri zosinthidwa, monga magalasi a fiber, filler yamchere, mankhwala amoto amoto ndi mapulasitiki ena.
PC imakhala ndi madzi osawuka komanso kutentha kwambiri, kotero kuti kukonza kwa zinthu zambiri zosinthidwa kumafunikira kapangidwe ka jekeseni wapadera.

Magawo akuthupi a PC resin
Kachulukidwe: 1.18-1.22 g / cm ^ 3 mulingo wokulitsa wolimba: 3.8 * 10 ^ -5 cm / C kutentha kwamphamvu: 135 C kutentha pang'ono - 45 CPC (Polycarbonate) ndi yopanda utoto, wowonekera, wosagwira kutentha, wosagwira, lawi-wamtundu uliwonse BI kalasi, ndipo ali wabwino katundu makina kutentha ntchito wamba. Poyerekeza ndi polymethyl methacrylate, polycarbonate imathandizira kukana, cholozera chokwanira chokwanira komanso magwiridwe antchito abwino. Ili ndi utakhazikika wamoto wa UL94 V-2 popanda zowonjezera. Kutha kwa polycarbonate ndikosauka. Zida zina za polycarbonate zogwiritsa ntchito mosavomerezeka zimafunikira chithandizo chapadera chapamwamba.
Kodi PC utomoni ntchito?
Zinthu zakuthupi za PC zimakhala ndi kutentha kwambiri, mphamvu yayikulu, kulimba kwabwino, kukana kwamphamvu, kutentha kwamoto, kutentha kwambiri, kosakhala kawopsedwe, kuwonekera kwa 90%, komanso mawonekedwe abwino otentha. Mkulu azithunzi omwe tikunena bata, mlingo shrinkage ndi otsika kwambiri, ambiri 0,1% ~ 0,2%. Amagwiritsidwa ntchito kwambiri ngati: zida zamagetsi, kuyatsa kwamagetsi, zida zamankhwala, tableware, makina ndi zinthu zina ndi zida zina.

Kodi ndondomeko jekeseni akamaumba zakuthupi PC utomoni ndi chiyani?
1. Mankhwala apulasitiki
PC ili ndi mlingo wokwanira wamadzi. Iyenera kutenthedwa ndi kuyanika isanachitike. PC yoyera imawumitsidwa pa 120 C. PC yosinthidwa nthawi zambiri imawuma pa 110 C kwa maola opitilira 4. Nthawi yoyanika sayenera kupitirira maola 10. Mwambiri, njira yolumikizira mpweya m'mlengalenga itha kugwiritsidwa ntchito kudziwa ngati kuyanika ndikokwanira.
Gawo la zida zobwezerezedwanso limatha kufikira 20%. Nthawi zina, zinthu 100% zobwezerezedwanso zitha kugwiritsidwa ntchito, ndipo kulemera kwake kumatengera zofunikira za malonda. Zida zobwezerezedwanso sizingasakanize mitundu yosiyanasiyana yaukadaulo nthawi imodzi, apo ayi zinthu zomwe zatsirizidwa zidzawonongeka kwambiri.
2. Kusankha jekeseni akamaumba Machine
Chifukwa cha mtengo komanso zifukwa zina, mapulogalamu a PC tsopano amagwiritsa ntchito zida zosinthidwa, makamaka zamagetsi, komanso amafunika kuwonjezera kukana moto. M'kati kupanga PC lawi-wamtundu uliwonse ndi zinthu zina pulasitiki aloyi, lamulo la dongosolo plasticizing wa makina jekeseni akamaumba ndi kusanganikirana wabwino ndi dzimbiri kukana. Zovuta zopangira pulasitiki ndizovuta kukwaniritsa. Mukamasankha ndi kugula, ziyenera kutsimikizika. Ziyenera kufotokozedweratu.
3.Kapangidwe ka Nkhungu ndi Chipata
Kutentha kwa nkhungu ndi 80-100 C, kuphatikiza magalasi ndi 100-130 C, zopangidwa zing'onozing'ono zitha kugwiritsidwa ntchito ngati chipata cha singano, kuzama kwazipata kuyenera kukhala 70% ya gawo lokulirapo, zipata zina zimakhala ndi mphete komanso zamakona anayi.
Kukula kwa chipata, kumathandiza kuti muchepetse zofooka zomwe zimadza chifukwa chometa kwambiri mapulasitiki. Kuzama kwa utsi kuyenera kukhala kochepera 0.03-0.06mm, ndipo wothamangayo ayenera kukhala waufupi komanso wozungulira momwe angathere. Kutsetsereka kwa chiwonongeko nthawi zambiri kumakhala pafupifupi 30'-1 degree
4. Sungunulani kutentha
Njira ya jekeseni wamlengalenga itha kugwiritsidwa ntchito kudziwa kutentha kwa kutentha. Nthawi zambiri, kutentha kwa PC ndi 270-320 C, ndipo PC ina yosinthidwa kapena yotsika ndi 230-270 C.
5. Liwiro la jekeseni
Sizachilendo kugwiritsa ntchito liwiro la jekeseni mwachangu kuti lipangidwe, monga kuyatsa ndi kuzimitsa zida zamagetsi. Kawirikawiri amachedwa kuthamangira mofulumira.
6, kuthamanga kwakumbuyo
Kupsyinjika kwakumbuyo kwa bar ya 10 kumatha kuchepetsedwa moyenera pakakhala zovuta komanso zolaula.
7. Nthawi yotsekera
Ngati nkhaniyo imakhala kutentha kwambiri kwa nthawi yayitali, imanyozetsa, imasula CO2 ndikusintha chikaso. Osatsuka mbiya ndi LDPE, POM, ABS kapena PA. Gwiritsani ntchito PS kuyeretsa
PC resin ndi imodzi mwazinthu zinayi zamapulasitiki zomwe zimagwiritsidwa ntchito kwambiri. Mestech yakhala ikugwiritsa ntchito mapulasitiki a PC ndi ma alloys ake popangira jekeseni kuti apange ziwalo zosiyanasiyana za pulasitiki. Ndife odzipereka kutumikira makasitomala ndi akamaumba ndi jekeseni akamaumba wa mtundu uwu wa mankhwala. Ngati ndi kotheka, lemberani.
