Vica softening point yog hais txog engineering plastics, cov yas dav dav thiab lwm cov qauv polymer hauv cov kua hluav taws xob hloov nruab nrab, nyob rau hauv ib qho kev thauj khoom, qee qhov ntsuas kub, yog 1mm2 koob nias rau hauv qhov tob ntawm 1mm kub.
Vica softening point yog siv los tswj cov khoom siv polymer zoo thiab ua qhov taw qhia txhawm rau txheeb xyuas cov thermal zog ntawm ntau yam tshiab.Nws tsis sawv cev rau qhov kub ntawm cov khoom siv.
English Heat deflection kub (HDT) yog ib qho parameter tsom rau kev qhia txog kev sib raug zoo ntawm cov cua sov nqus thiab deflection ntawm cov khoom ntsuas.
Lub thermal deformation kub yog ntsuas los ntawm qhov kub thiab txias tau sau tseg raws li qhov teev tseg thiab cov duab sib txawv.
Softening point: qhov kub ntawm qhov khoom softens.
Feem ntau yog hais txog qhov kub ntawm qhov amorphous polymer pib soften.
Nws tsis yog tsuas yog cuam tshuam nrog cov qauv ntawm polymer, tab sis kuj muaj feem xyuam rau nws qhov hnyav molecular.
Muaj ntau txoj kev txiav txim siab.
Cov txiaj ntsig ntawm kev txiav txim siab sib txawv feem ntau tsis sib xws.
Feem ntau siv yogVicatthiab txoj cai thoob ntiaj teb.
Thermal deformation kub: Ntsuas qhov deformation (los yog softening) ntawm cov qauv nyob rau hauv ib tug tej yam load rau ib tug tej yam kub.
Thermal deformation kub: Siv tus qauv spline ua piv txwv, nyob rau hauv ib qho kev ntsuas cua sov thiab kev thauj khoom, qhov sib thooj kub thaum lub spline deflection hloov los ntawm 0.21mm.
Vica softening point: ntawm qee qhov cua sov thiab thauj khoom, lub indenter rau hauv tus qauv qauv 1 hli ntawm qhov sib xws.
Muaj ob tus qauv rau cua sov tus nqi thiab thauj khoom.
