Okokuqala, yini ipulasitiki
1) Izinto zokusetshenziswa zePlastiki (impahla ethengiswayo ye-LC plastic eluhlaza, izinto zepulasitiki ezimelana nokushisa okuphezulu, i-PPS, i-LCP, i-PET, i-PA, abahlinzeki bempahla yepulasitiki ye-PES): ingxenye eyinhloko yi-resin, eyakhiwe nge-polymer synthetic resin njengenhloko eyinhloko. ingxenye futhi ingene ezintweni ezisizayo ezihlukahlukene Impahla noma isithasiselo, esine-plasticity kanye nokuhamba ekushiseni okukhethekile nokucindezela, singabunjwa sibe yisimo esithile, futhi sihlale siyinto engashintshi ukuma ngaphansi kwezimo ezithile;
2) Ipulasitiki inezinto ezinhle zokuvikela ugesi, ukushisa nomsindo: ukuvala ugesi, ukumelana ne-arc, ukonga ukushisa, ukuvala umsindo, ukumunca umsindo, ukumuncwa kokudlidliza, nokusebenza kokuthulisa umsindo.
3) Iningi lezinto zokusetshenziswa zepulasitiki zikhishwa kwamanye amafutha.Ingxenye eyaziwa kakhulu yezinto ze-PC (ipulasitiki ye-polycarbonate) ikhishwa ku-petroleum.
Izinto ze-PC zinephunga likaphethiloli lapho zishiswa;I-ABS (acrylonitrile-butadiene-styrene copolymer plastic) ikhishwa emalahleni,
I-ABS izoba sesimweni somsizi lapho ushiswa;I-POM (ipulasitiki ye-polyoxymethylene) ikhishwa kugesi yemvelo,
I-POM inephunga legesi elinuka kakhulu uma isiqedile ukusha.
Izimpawu zezinto zokusetshenziswa zepulasitiki ezijwayelekile (impahla yokusetshenziswa ye-LC yepulasitiki ethengiswayo, izinto zepulasitiki ezimelana nokushisa okuphezulu, i-PPS, i-LCP, i-PET, i-PA, abahlinzeki bempahla yepulasitiki ye-PES):
I-1) Izinto zepulasitiki zicindezelwa ukushisa, futhi i-coefficient yokunwetshwa komugqa inkulu kakhulu kuneyensimbi;
2) Ukuqina kwezinto ezijwayelekile zepulasitiki kuyi-oda lobukhulu obuphansi kunelensimbi;
I-3) Izakhiwo zemishini yezinto zokusetshenziswa zepulasitiki zizoncishiswa kakhulu ngaphansi kokufudumeza isikhathi eside;
I-4) Ngokuvamile, izinto zokusetshenziswa kwepulasitiki zigcizelelwa okwesikhashana ekamelweni lokushisa futhi ngaphansi kokucindezeleka okuphansi kunamandla okukhiqiza, futhi ukuguqulwa okungapheli kuzokwenzeka;
I-5) Ukuthengiswa kwezinto ezingavuthiwe zepulasitiki kuzwela kakhulu ekulimaleni kwegebe;
6) Izakhiwo zemishini yezinto zokusetshenziswa zepulasitiki ngokuvamile ziphansi kakhulu kunezinsimbi, kodwa amandla athile kanye ne-modulus ethize yezinye izinto eziyinhlanganisela ziphakeme kunezinsimbi.Uma ukwakheka komkhiqizo kunengqondo, kuzoba nenzuzo enkulu;
7) Ngokuvamile, izakhiwo zemishini yezinto zokusetshenziswa zepulasitiki eziqinisiwe ziyi-anisotropic;
I-8) Ezinye izinto zepulasitiki zizomunca umswakama futhi zenze izinguquko ngosayizi nokusebenza;
9) Amanye amapulasitiki ayavutha.
Ukuhlukaniswa kwe-Plastiki eluhlaza (i-LC plastic eluhlaza impahla ethengiswayo, impahla yepulasitiki engamelana nokushisa okuphezulu, i-PPS, i-LCP, i-PET, i-PA, umphakeli we-PES we-plastic eluhlaza)
Izinto zokusetshenziswa zepulasitiki zilandela ukwakheka kwamangqamuzana okwenziwa kwama-synthetic resins futhi zihlukaniswa ikakhulukazi amapulasitiki ashisayo kanye ne-thermosetting: amapulasitiki ashisayo abhekisa kumapulasitiki aseyipulasitiki ngemuva kokushisa okuphindaphindiwe: ikakhulukazi i-PE÷PP÷PVC÷PS÷ABS÷PMMA÷POM÷PC÷ I-PA kanye nezinye izinto ezivamile zokusetshenziswa.Amapulasitiki e-thermosetting ikakhulukazi abhekisela kumapulasitiki enziwe ngezinsalela zokwenziwa eziqinisa ukushisa, njengamapulasitiki athile e-phenolic namapulasitiki angama-amino, angasetshenziswa kakhulu.
Ngokobubanzi bokusebenza, kukhona ikakhulukazi amapulasitiki enhloso ejwayelekile njenge-PE÷PP÷PVC÷PS, njll., namapulasitiki obunjiniyela afana ne-ABS÷POM÷PC÷PA nezinye izinhlobo ezisetshenziswa kakhulu.Ngaphezu kwalokho, kukhona amapulasitiki akhethekile afana nokushisa okuphezulu, umswakama ophezulu kanye nokumelana nokugqwala kanye namanye amapulasitiki alungiselwe izinjongo ezikhethekile.
Manje kufanele ucace, ipulasitiki ayiyona ipulasitiki, kodwa ingxenye yayo eyinhloko i-resin, futhi ingxenye eyinhloko yepulasitiki nayo i-resin.Okubili kuyisici esiyinhloko esifanayo, akuyona into efanayo.
