Okokuqala, yintoni iplastiki
1) imathiriyeli ekrwada yePlastiki (impahla ekrwada ye-LC yeplastiki, i-PPS, i-LCP, i-PET, i-PA, i-PES yabathengisi bezinto zeplastiki): eyona nto iphambili yi-resin, eyenziwe nge-polymer synthetic resin njengeyona nto iphambili. icandelo kunye nokungeniswa kwizinto ezahlukeneyo ezincedisayo Izinto eziphathekayo okanye izongezo, ezineplastiki kunye nokuhamba kwiqondo lokushisa elithile kunye noxinzelelo, unokubunjwa kwimilo ethile, kwaye ihlale iyinto engatshintshiyo kwimilo phantsi kweemeko ezithile;
I-2) Iplastiki ineempawu ezilungileyo zokugquma umbane, ubushushu kunye nesandi: ukugquma kombane, ukumelana ne-arc, ukugcinwa kobushushu, ukugquma isandi, ukufunxa isandi, ukufunxa i-vibration, kunye nokusebenza kokuthulisa isandi.
3) Uninzi lwezixhobo zeplastiki zitsalwa kwezinye ioyile.Inxalenye eqhelekileyo yezinto zePC (iplastiki ye-polycarbonate) ikhutshwe kwi-petroleum.
Izinto zePC zinevumba lepetroli xa litshiswa;I-ABS (iplastiki ye-acrylonitrile-butadiene-styrene copolymer) ikhutshwe kumalahle,
I-ABS iya kuba kwimo yothuthu xa itshiswa;I-POM (iplastiki ye-polyoxymethylene) ikhutshwe kwigesi yendalo,
I-POM inerhasi enuka kakhulu xa igqibile ukutshisa.
Iimpawu zeplastiki yemathiriyeli ekrwada ngokubanzi (impahla yeplastiki ye-LC yeplastiki ethengisiweyo, izixhobo zeplastiki ezinobushushu obuphezulu, i-PPS, i-LCP, i-PET, i-PA, i-PES abathengisi bezinto zeplastiki ekrwada):
I-1) Izinto zeplastiki zinyanzeliswa ngubushushu, kwaye i-coefficient yokwandiswa komgca inkulu kakhulu kuneyetsimbi;
2) Ubunzima bezinto zeplastiki eziqhelekileyo ngumyalelo wobukhulu obungaphantsi kunezinyithi;
3) Iimpawu zomatshini wezinto eziluhlaza zeplastiki ziya kuncitshiswa kakhulu phantsi kokufudumeza ixesha elide;
4) Ngokuqhelekileyo, izinto eziluhlaza zeplastiki zigxininiswe okwethutyana kwiqondo lokushisa lokushisa kwaye phantsi koxinzelelo oluphantsi kunamandla okuvelisa, kunye nokuguqulwa okusisigxina kuya kwenzeka;
5) Ukuthengiswa kwempahla yeplastiki ekrwada kunovakalelo kakhulu kumonakalo wesikhewu;
6) Iimpawu zoomatshini bezinto eziluhlaza zeplastiki zihlala ziphantsi kakhulu kunezo zesinyithi, kodwa amandla athile kunye nemodyuli ethile yezinye izinto ezidibeneyo ziphezulu kunezo zesinyithi.Ukuba uyilo lwemveliso lunengqiqo, luya kuba luncedo ngakumbi;
7) Ngokuqhelekileyo, iipropathi zoomatshini bezinto ezikrwada zeplastiki ezomeleziweyo ziyi-anisotropic;
8) Ezinye izinto zeplastiki ziyakuthatha umswakama kwaye zenze utshintsho kubukhulu kunye nokusebenza;
9) Ezinye iiplastiki ziyatsha.
Ukuhlelwa kwezinto zeplastiki ekrwada (i-LC yeplastiki yemathiriyeli ekrwada ihoseyili, ubushushu obuphezulu bezinto zeplastiki ezixhathisayo, i-PPS, i-LCP, i-PET, i-PA, i-PES umthengisi wezinto zeplastiki ekrwada)
Izinto zeplastiki eziluhlaza zilandela isakhiwo se-molecular of synthetic resins kwaye zahlulwe kakhulu kwiiplastiki ze-thermoplastic kunye ne-thermosetting: iiplastiki ze-thermoplastic zibhekisela kwiiplastiki eziseziplastiki emva kokufudumeza okuphindaphindiweyo: ubukhulu becala PE÷PP÷PVC÷PS÷ABS÷PMMA÷POM÷PC÷ PA kunye nezinye izinto eziqhelekileyo ekrwada.Iiplastiki ze-Thermosetting ikakhulu zibhekisa kwiiplastiki ezenziwe ngeereyini zokwenziwa eziqinisa ubushushu, ezifana neeplastiki zephenolic kunye neeplastiki zeamino, ezingasetyenziswanga ngokuqhelekileyo.
Ngokobubanzi besicelo, kukho iiplastiki zenjongo ngokubanzi ezifana ne-PE÷PP÷PVC÷PS, njl., kunye neeplastiki zobunjineli ezifana ne-ABS÷POM÷PC÷PA kunye nezinye iintlobo ezisetyenziswa ngokuqhelekileyo.Ukongeza, kukho iiplastiki ezikhethekileyo ezifana nobushushu obuphezulu, ukufuma okuphezulu kunye nokumelana nomhlwa kunye nezinye iiplastiki eziguqulelwe ngeenjongo ezizodwa.
Ngoku kufuneka ucace, iplastiki ayikho iplastiki, kodwa inxalenye yayo ephambili yi-resin, kwaye inxalenye ephambili yeplastiki nayo i-resin.Ezi zimbini zizinto ezingundoqo ezifanayo, hayi into enye.
