PC intlaka ziphene yokubumba
Inkcazo emfutshane:
I-PC resin (i-polycarbonate) iinxalenye zokubumba inaliti zisetyenziswa kakhulu kwiimveliso zombane, iigobolondo zezixhobo zombane kunye neemveliso zombane.
PC iindawo intlaka ziphene yokubumba ezisetyenziswa ngokubanzi kwiimveliso zombane, amaqokobhe isixhobo zombane kunye neemveliso zombane.
Yintoni i-PC resin?
Yintoni i-PC resin (i-polycarbonate) eyaziwa ngokuba yi-polycarbonate, ngenxa yeempawu zayo ezigqwesileyo, ezaziwa njengeglue-proof glue. I-PC ineempawu zamandla aphezulu oomatshini, uluhlu olubanzi lobushushu, ukusebenza kakuhle kombane (kodwa i-arc ukumelana ayitshintshi), uzinzo olulinganiselweyo nolwenza izinto elubala.
Umbala wokuqala wePC awunambala kwaye ubala. Imibala eyahlukeneyo ebonakalayo, eguqukayo kunye ne-opaque kunye neepropathi zokusasaza ukukhanya zinokufumaneka ngokongeza i-toner okanye i-master batch. Oku kwenza kube lula ukwenza imibala yesibane kunye nezinye iinxalenye ezinemibala eyahlukeneyo.PC ikwanazo neemveliso ezininzi eziguqulweyo, ezinjengeglasi yefayibha, ukugcwaliswa kwezimbiwa, ukudodobala kwelangatye ngamachiza nezinye iiplastiki.
I-PC ine-fluidity ehlwempuzekileyo kunye nobushushu obuphezulu bokuqhubekeka, ke ukuqhubekeka kwamabakala amaninzi ezinto eziguqulweyo kufuna ukuba kwenziwe inaliti ekhethekileyo.
Imibala eyahlukeneyo emva kokongeza i-toner okanye i-masterbatch
Umbala wokuqala we-PC resin
Iiparamitha ezibonakalayo ze-PC resin
Ubuninzi: 1.18-1.22 g / cm ^ 3 inqanaba lokwanda komgama: 3.8 * 10 ^ -5 cm / C ubushushu obuguquliweyo obushushu: 135 C ubushushu obuphantsi-45 CPC (iPolycarbonate) ayinambala, iyabonakala, ayinako ubushushu, ayichaphazeli, ilangatye-nekudodobalisa BI grade, kwaye iipropati elungileyo ngoomatshini kwiqondo lobushushu ukusetyenziswa eqhelekileyo. Xa kuthelekiswa ne-polymethyl methacrylate, i-polycarbonate inefuthe elifanelekileyo lokumelana, isalathiso sokuphinda sisebenze kunye nokusebenza kakuhle. Ine-UL94 V-2 retardancy yedangatye ngaphandle kwezongezo. Ukuxhathisa ukunxiba kwe-polycarbonate kuhlwempuzekile. Ezinye izixhobo ze-polycarbonate zezicelo ezinxibayo zifuna unyango olukhethekileyo kumphezulu.
Yintoni PC nentlaka Isetyenziselwa?
Izinto zePC zinokumelana nobushushu obuphezulu, amandla aphezulu, ukomelela okuhle, ukumelana nefuthe, ukudodobalisa idangatye, uluhlu olubanzi lokusetyenziswa kobushushu, ukungabinetyhefu, ukungafihli ukuya kuthi ga kwi-90%, kunye neepropathi ezilungileyo zoomatshini kubushushu obufanayo. Uzinzo oluphezulu, ubukhulu be-shrinkage buphantsi kakhulu, ngokubanzi yi-0.1% ~ 0.2%. Isetyenziswa ngokubanzi: izixhobo zombane, ukukhanya kwamehlo, izixhobo zonyango, itafile, oomatshini kunye nezinye iimveliso kunye nezixhobo.

Yintoni na inkqubo ziphene yokubumba izinto nentlaka PC?
1. Unyango lweplastikhi
I-PC inezinga eliphezulu lokufunxa amanzi. Kufuneka ifakwe kwangaphambili kwaye yomiswe ngaphambi kokuba yenziwe. I-PC echanekileyo yomile kwi-120 C. I-PC eguqulweyo ihlala yomiswe kwi-110 C ngaphezulu kweeyure ezingama-4. Ixesha lokomisa akufuneki lidlule kwiiyure ezili-10. Ngokubanzi, indlela yokuhambisa umoya-nomoya ingasetyenziselwa ukumisela ukuba ukomisa kwanele.
Umyinge wezinto ezinokuphinda zisetyenziswe zinokufikelela kuma-20%. Kwezinye iimeko, i-100% yezinto eziphinda zisetyenziswe zinokusetyenziswa, kwaye ubunzima boqobo buxhomekeke kwiimfuno zomgangatho wemveliso. Izinto ezihlaziyiweyo ezinokuphinda zenziwe aziyi kuxubeka imibala eyahlukeneyo ngexesha elinye, kungenjalo iipropathi zeemveliso ezigqityiweyo ziya konakala kakhulu.
2. Ukukhethwa Machine Inaliti Ukubumbela Machine
Ngenxa yeendleko kunye nezinye izizathu, iimveliso zePC ngoku zisebenzisa izinto eziguqulweyo ngakumbi iimveliso zombane, kodwa kufuneka zonyuse ukumelana nomlilo. Kwinkqubo yokubumba PC ilangatye-nekudodobalisa kunye nezinye iimveliso ingxubevange zeplastiki, imfuneko inkqubo plasticizing umatshini ziphene yokubumba ukuxuba elungileyo kunye nokumelana. Isikali esiqhelekileyo seplastikhi kunzima ukufezekisa. Xa ukhetha kwaye uthenga, kufuneka uqiniseke. Kufuneka ichazwe kwangaphambili.
3. Uyilo lweMold and Gate
Ubushushu obuqhelekileyo bokungunda yi-80-100 C, kunye nefayibha yeglasi yi-100-130 C, iimveliso ezincinci zingasetyenziswa esangweni lenaliti, ubunzulu besango kufuneka bube yi-70% yenxalenye eshinyeneyo, amanye amasango aneringi kunye noxande.
Okukhona isango likhulu, kokukhona kungcono ukunciphisa iziphene ezibangelwa kukucheba ngokugqithiseleyo iiplastikhi. Ubunzulu bomngxuma wokukhupha kufuneka ubengaphantsi kwe-0.03-0.06mm, kwaye imbaleki kufuneka ibe mfutshane kwaye ijikeleze kangangoko. Ithambeka lokutshatyalaliswa ngokubanzi malunga ne-30'-1 degree
4. Melt ubushushu
Indlela yenaliti yomoya ingasetyenziselwa ukumisela ubushushu bokuqhubekeka. Ngokubanzi, ubushushu bokusebenza kwePC yi-270-320 C, kwaye ezinye zilungisiwe okanye ziphantsi i-PC yesisindo semolekyuli yi-230-270 C.
5. Isantya sokutofa
Kuqhelekile ukusebenzisa isantya senaliti ngokukhawuleza ukumila, njengokucima nokucima izixhobo zombane. Okuqhelekileyo kuyacotha ukubonisa ngokukhawuleza.
6, uxinzelelo lwasemva
Uxinzelelo lwasemva malunga ne-10 bar lunokuncitshiswa ngokufanelekileyo ngokungabikho kwe-airmark kunye nephonografi.
7. Ixesha lokuvalelwa
Ukuba izinto zihlala kubushushu obuphezulu ixesha elide, ziya kuthoba isidima, zikhulule i-CO2 kwaye zibe tyheli. Sukucoca umphanda nge-LDPE, i-POM, i-ABS okanye i-PA. Sebenzisa i-PS ukucoca
I-PC resin yenye yezinto ezine ezisetyenziswa ngokuxhaphakileyo zeplastiki. Kudala iMestech isebenzisa iiplastikhi zePC kunye neealloys zayo ekubumbeni ngenaliti ukuvelisa iindawo ezahlukeneyo zeplastiki. Sizimisele ekukhonzeni abathengi ngokubumba kunye nenaliti yokubumba olu hlobo lweemveliso. Ukuba kukho imfuneko, nceda uqhagamshelane nathi.
