Mapurasitiki ezvigadzirwa zvakasiyana ane nzvimbo dzakasiyana dzekunyungudika:
Polypropylene: Tembiricha yekunyunguduka i165 ° C-170 ° C, kugadzikana kwekupisa kwakanaka, tembiricha yekuora inogona kusvika pamusoro pe300 ° C, uye inotanga kushanduka yero uye kuderera pa260 ° C kana yasangana neokisijeni. , uye ine anisotropy panguva yakaderera-tembiricha kuumbwa.Zviri nyore kumonyoroka kana kumonyaniswa nekuda kwemamorekuru, uye ine kuita kwakanaka kwekupeta.Idzo resin zvidimbu zvine waxy magadzirirwo.Avhareji yekunwa mvura iri pasi pe0.02%.Iyo inotenderwa mwando yemukati yekuumba ndeye 0.05%.Naizvozvo, kuomesa kazhinji hakuitwe panguva yekuumba.Inogona kuomeswa paanenge 80 ° C kwemaawa 1-2, uye maitiro ayo ekuyerera anonzwa kune tembiricha uye shear rate panguva yekuumbwa.
Polyoxymethylene: Ipurasitiki isingaiti kupisa uye inonyunguduka inosvika 165 ° C, iyo inozoora zvakanyanya uye kushanduka yero pakupisa kwe240 ° C.Nguva yekugara pakupisa kwe210 ° C haifaniri kudarika maminitsi makumi maviri.Munzvimbo yakajairika yekudziya, inoora kana ichidziya kwenguva yakareba., Mushure mekuora, pachava nekunhuhwirira uye kubvarura.Chigadzirwa chacho chinoperekedzwa nemitsetse yero-brown.Density yePOM ndeye 1.41-1.425.-5 maawa.
Polycarbonate: inotanga kupfava pa215°C, inotanga kuyerera inopfuura 225°C, kunyungudusa viscosity iri pasi pe260°C yakakwira zvakanyanya, uye chigadzirwa chinowanzoita kusakwana.Tembiricha yekuumba kazhinji iri pakati pe270°C ne320°C.Kana tembiricha ichipfuura 340 ° C, kuora kuchaitika, uye kuomesa tembiricha Tembiricha iri pakati pe120 ℃—130 ℃, uye nguva yekuomesa inopfuura maawa mana.Iyo polycarbonate resin kazhinji haina ruvara uye yakajeka zvimedu.
