Abavelisi bebhodi yokugquma i-SMC bathetha ngeempawu zemathiriyeli yokugquma

①Iiplastiki ezininzi zikhaphukhaphu ngobunzima, zizinzile ngokwekhemikhali, kwaye aziyi kuhlwa;

②Ukumelana nempembelelo elungileyo;

③Inokungafihli kakuhle kunye nokumelana nokunxiba;

④I-insulation elungileyo kunye ne-thermal conductivity ephantsi;

⑤Ukwakheka ngokubanzi, ukubala kakuhle, ixabiso eliphantsi lokuqhuba;

⑥Iiplastiki ezininzi azikwazi ukumelana nobushushu, izinga eliphezulu lokwanda kwe-thermal kwaye kulula ukutshisa;

⑦ Uzinzo olungekho mgangathweni kunye nokuguqulwa lula;

⑧Iiplastiki ezininzi zinokuxhathisa ubushushu obuphantsi kwaye ziba brittle kubushushu obuphantsi;

⑨ Ukuguga kulula;

⑩ Ezinye iiplastiki zinyibilika ngokulula kwizinyibilikisi.

Iiplastiki zinokwahlulwa zibe ngamacandelo amabini: i-thermosetting kunye ne-thermoplastic. Eyangaphambili ayinakuguqulwa kwaye isetyenziswe, kwaye le yokugqibela inokuveliswa ngokuphindaphindiweyo. Kukho iindidi ezimbini zezakhiwo zeepolima zeplastiki:

Eyokuqala yisakhiwo somgca, kwaye i-polymer compound kunye nesi sakhiwo ibizwa ngokuba yi-linear polymer compound;

Okwesibini luhlobo lwesakhiwo somzimba, kunye nekhompawundi ye-polymer enesi sakhiwo ibizwa ngokuba yi-body type polymer compound.

Ezinye iipolymers zinamatyathanga ebranched, abizwa ngokuba ziipolymers zebranched, ezesakhelo somgca. Nangona ezinye iipolymers zinee-cross-links phakathi kwee-athomu, zingaphantsi kwe-cross-linked, ebizwa ngokuba yi-network structure kwaye iyingxenye yesakhiwo somzimba. Izakhiwo ezibini ezahlukeneyo, ezibonisa iimpawu ezimbini ezichaseneyo. Isakhiwo somgca (kubandakanywa nesakhiwo se-branched) iipolymers zineempawu ze-elasticity kunye neplastiki ngenxa yobukho beamolekyu ezizimeleyo, ezinokuchithwa kwi-solvents, zinokuncibilika ngokufudumeza, kwaye zibe nobunzima obuphantsi kunye ne-brittleness. Ekubeni akukho macromolecules ezizimeleyo, i-polymer efana nomzimba ayinayo i-elasticity kunye neplastiki, ayikwazi ukunyibilika kwaye inyibilike, kodwa inokuvuvukala kuphela, kwaye inobunzima obuphezulu kunye ne-brittleness. Iiplastiki zinezakhiwo ezibini zeepolymers, i-thermoplastics eyenziwe ngeepolymers ezinqamlekileyo, kunye neeplastiki ze-thermosetting ezenziwe ngeepolima ezininzi.
