Izithako main kanye izakhiwo plastic
Amapulasitiki avamile wonke enziwe ngezinto zemvelo ezifana ne-cellulose, amalahle, igesi yemvelo, usawoti kanye namafutha angcolile ngokusebenzisa inqubo ye-polymerization noma i-polycondensation, futhi kokubili kudinga ama-catalysts athile.Ku-reactor ye-polymerization, ama-monomers afana ne-ethylene ne-propylene axhunywe ndawonye ukuze akhe amaketanga amade e-polymer.I-polymer ngayinye inezici zayo, ukwakheka kanye nosayizi kuye ngezinhlobo ezahlukahlukene zama-monomer ayisisekelo asetshenziswa.
Kunezinhlobo eziningi ezahlukene zamapulasitiki, kodwa zingahlukaniswa zibe imindeni emibili eyinhloko ye-polymer:
1.I-Thermoplastics (ethambisayo ekushiseni bese iqinisa futhi ekupholiseni).
2.Ama-Thermosets (angaze athambe uma esebunjiwe).
Yiziphi izinsizakalo esingazihlinzeka mayelana namapulasitiki
Izinhlobo zokujova zepulasitiki:
Ukubumba umjovo kungenye yezindlela zokukhiqiza ezisetshenziswa kakhulu zezingxenye zepulasitiki futhi kuyisisekelo samakhono okukhiqiza we-RuiCheng.Ukubumba umjovo ukujova into eshisayo ibe iphethini, ebizwa ngokuthi isikhunta, ebese ipholisa ibe ingxenye yocezu olulodwa enekhwalithi ephezulu, eqinile, futhi ephindaphindekayo.
Ukubunjwa komjovo kuyaphindaphindeka kakhulu, okwenza kube kuhle ekuhambisaneni komkhiqizo nokwethenjwa kwengxenye.Lokhu kwenza ukubumba komjovo kusebenze kahle kakhulu futhi kungabizi kakhulu ekukhiqizeni umthamo omkhulu.
uma usikhetha njengomphakeli wakho wezingxenye zepulasitiki, singakunikeza amanani ashibhile kakhulu kanye nomkhiqizo wekhwalithi ephezulu kakhulu
Isikhunta esisheshayo sokujova:
Ukubumba komjovo osheshayo (i-RIM) kuyinqubo yokubumba yomjovo eklanyelwe ukwakhiwa kwamaqoqo amancane ezingxenye zepulasitiki ezinezikhathi zokuhola ezimfushane kakhulu kunenqubo evamile yokubumba umjovo.Ngokuvamile, izinto ezisetshenziselwa i-RIM ziyefana nalezo ezisetshenziselwa ukubumba umjovo ojwayelekile wokukhiqiza ngaphandle kokuthi izibungu zokujova ze-RIM zenzelwe ukushintshwa ngokushesha esikhundleni sokuqina kochungechunge olude lokukhiqiza.
I-Overmolding:
I-Overmolding iyinqubo yokubumba yomjovo enezinyathelo eziningi lapho izingxenye ezimbili noma ngaphezulu zibunjwa phezu kwesinye.I-Overmolding ngezinye izikhathi ibizwa ngokuthi ukubumba okuphindwe kabili ngoba kuyisinyathelo esinezinyathelo ezimbili.
Okokuqala, ingxenye eyisisekelo (okunye eyaziwa ngokuthi i-substrate) iyabunjwa futhi ivunyelwe ukwelapha.Ama-substrates agaywe ngokweqile avame ukwenziwa ngepulasitiki.Khona-ke, ungqimba lwesibili lubunjwa ngokuqondile phezulu kweyokuqala ukuze kwakhiwe ucezu olulodwa oluqinile.I-Overmolding ivame ukusetshenziselwa ukwenza izingxenye zepulasitiki ezinesibambo senjoloba.Inqubo yamashothi amabili yokumboza ngokweqile isixubho, isibonelo, ihlanganisa ukwenza isendlalelo sesisekelo sesibambo sepulasitiki kanye nongqimba lwerabha olungaphezulu (ukwenza isixubho singasheleli ukubamba).
Isikhunta esinemibala emibili:
Ukubumba umjovo onemibala emibili kuyinqubo yokukhiqiza esetshenziswa uma kubhekiselwa ekubumbeni izinto/imibala emibili ibe ingxenye eyodwa yepulasitiki, okuwubuchwepheshe obuhlanganisa izinto ezimbili noma imibala emibili ehlukene ibe ingxenye eyodwa yepulasitiki yesiphetho ngokusebenzisa umshini wokubumba umjovo ongu-2k.
Ukusetshenziswa kwezingxenye zepulasitiki
Amapulasitiki athuthukile abalulekile ekwakhiweni kwezimoto.Cishe yonke ikhwalithi yemoto yesimanje-kusukela kwezokuphepha nokusebenza kuya ekusebenzeni kahle kanye nobuhle-incike kumapulasitiki futhi, ngokwandayo, izinhlanganisela ze-polymer ukuze kuhlangatshezwane nalokho okulindelwe ngabathengi okuhlala kuvela.
Njengomphakeli wepulasitiki waseChina, siyanaka futhi ukusebenzisa ipulasitiki embonini yezimoto futhi sigxile ekwakhiweni kwezingxenye zepulasitiki ezisezingeni eliphakeme kakhulu.Imikhiqizo yethu idayiselwa yonke indawo, ikakhulukazi i-Europe Slovakia naseRomania.
Njengamanje ipulasitiki isetshenziswe kabanzi embonini yezemidlalo, izinto eziningi eziyingxenye yezemidlalo zenziwa ngepulasitiki.njengemishini yezemidlalo Isondo, isondo lomshini wokuphakela ibhola lomphebezo.Kule mishini yezemidlalo sivame ukusebenzisa i-overmoulding ukuvikela ingxenye ebalulekile.Izingxenye zepulasitiki zezemidlalo zethu zithandwa kakhulu eBrazil, uma udinga ukwazi okwengeziwe, sicela ubheke icala lethu noma imikhiqizo mayelana nezingxenye zepulasitiki zemidlalo.
Ngokwezinga elikhulu, amapulasitiki ezokwelapha ayahlukahluka ngezakhiwo nezici.Ngenxa yezidingo eziqinile zokulawula izingxenye zezokwelapha, onjiniyela bethu basebenzisa ama-polymer epulasitiki wezokwelapha ezinhlelweni ezithile zezempilo, kusukela kumathuluzi okuhlinza kuya ezintweni zokwelapha.Ukuze siqinisekise ukuthi lezi zingxenye zepulasitiki zezokwelapha ziyahlangabezana nezindinganiso zezokwelapha, senze izinkulungwane zokuhlola.Manje lawa mapulasitiki ezokwelapha asetshenziselwa ama-prototypes ezokwelapha kanye nezingxenye angaletha ukumelana okufanelekile nomthelela, ukuguga, izinga lokushisa kanye nokugqwala.Ngasikhathi sinye, lezi zingxenye zepulasitiki zingagcina ukusebenza okuphezulu ngemuva kokubhekana nokuvala inzalo noma umzimba.
Izinzuzo izingxenye plastic
➢ Idizayini evumelana nezimo
➢ Uhlu olubanzi lwezinto
➢ Ukubukeka okuhle kakhulu.
➢ Izikhathi zokukhiqiza ezisheshayo
➢ Ukuphindaphinda okukhulu nokubekezelelana
Imuphi upulasitiki esivame ukuwusebenzisa lapho sijova
Ukuze ufunde kabanzi mayelana nobuciko bomjovo wepulasitiki, ungaxhumana nathiithimba labadayisi ukuze lixoxe ngesicelo sakho esiyingqayizivele.
