Umahluko phakathi kwe-thermal deformation kunye ne-Vicar softening point

I-Vica softening point ibhekisela kwiiplastiki zobunjineli, iiplastiki eziqhelekileyo kunye nezinye iisampulu zepolymer kulwelo oludlulisa ubushushu obuphakathi, phantsi komthwalo othile, izinga elithile lobushushu, yi-1mm2 inaliti icinezelwe kubunzulu be-1mm yobushushu.

I-Vica softening point isetyenziselwa ukulawula umgangatho wepolymer kwaye njengesalathisi sokuchonga iimpawu ze-thermal zeentlobo ezintsha. Ayimeli iqondo lokushisa apho izinto zisetyenziswa.

Ubushushu besiNgesi obuguqukayo (HDT) yiparameter ejolise ekubonakaliseni ubudlelwane phakathi kokufunxwa kobushushu kunye nokuphambuka kwento elinganisiweyo.

Ukushisa kwe-thermal deformation kulinganiswa neqondo lokushisa elirekhodiweyo phantsi komthwalo ochaziweyo kunye neenguqu zemilo.

Softening point: iqondo lobushushu apho into ithamba khona.

Ikakhulu ibhekisa kwiqondo lobushushu apho ipholima yeamorphous iqala ukuthamba.

Ayihambelani kuphela nesakhiwo sepolymer, kodwa inxulumene nobunzima bayo bemolekyuli.

Zininzi iindlela zokumisela.

Iziphumo zeendlela ezahlukeneyo zokuzimisela zihlala zingahambelani.

Zisetyenziswa kakhuluVicatkunye nomthetho wehlabathi.

Iqondo lokushisa lokuguqulwa kwe-Thermal: Ukulinganisa i-deformation (okanye ukuthambisa) kwesampuli phantsi komthwalo othile kwiqondo lokushisa elithile.

Ukushisa kwe-thermal deformation: Thatha i-spline eqhelekileyo njengomzekelo, phantsi komlinganiselo othile wokufudumeza kunye nomthwalo, iqondo lokushisa elihambelanayo xa ukuphambuka kwe-spline kutshintsha nge-0.21mm.

I-Vica softening point: kwinqanaba elithile lokufudumala kunye nomthwalo, i-indenter kwisampuli eqhelekileyo ye-1mm yeqondo lokushisa elihambelanayo.

Kukho imigangatho emibini yomgangatho wokufudumeza kunye nomthwalo.
