Txhawm rau pib txiav txim siab seb cov khoom puas yog thermoset lossis thermoplastic, heat ib tus pas nrig (txog 500 ° F) thiab nias nws tawm tsam tus qauv. Yog hais tias tus qauv softens, cov khoom yog ib tug thermoplastic; Yog tsis yog, nws yog tej zaum thermosetting. Tom ntej no, tuav tus qauv rau ntawm ntug nplaim kom txog thaum nws taws.
Koj tuaj yeem qhia qhov txawv ntawm cov thermoplastic thiab thermosetting li cas?
Qhov sib txawv ntawm ob yogThermoset yog cov khoom siv uas muaj zog thaum cua sov, tab sis tsis tuaj yeem rov ua dua lossis ua kom sov tom qab pib tsim, thaum cov thermoplastics tuaj yeem rov ua dua, rov ua dua., thiab txias raws li qhov tsim nyog yam tsis muaj kev hloov tshuaj lom neeg.
Dab tsi yog cov yam ntxwv ntawm thermosetting plastics?
Properties: Ntxig, nkig, opaque, lub zog siab ntawm qhov kub siab, zoo tshuaj tiv thaiv, nws tus kheej tua, tsis muaj pa luam yeeb.
Txoj kev yooj yim tshaj plaws los txheeb xyuas cov yas yog dab tsi?
Ib txoj hauv kev yooj yim tshaj plaws los ua qhov ntsuas hluav taws xob yog txiav ib qho qauv ntawm cov yas thiab igniting hauv lub fume cupboard. Cov xim ntawm cov nplaim taws, cov ntxhiab tsw thiab cov yam ntxwv ntawm kev kub hnyiab tuaj yeem ua rau muaj qhov qhia txog hom yas: Polyethylene (PE) - Drips, tsw zoo li tswm ciab.
Koj tuaj yeem qhia tau li cas yog tias yas yog nkauj xwb?
Muab qhov yooj yim, nws yog polymer hauv nws daim ntawv ntshiab. Ntau cov polymers - xws li PTFE, PEEK thiab Nylons - yog siv los ntawm kev ntxiv cov muab tub lim xws li iav lossis carbon los txhim khocov khoom siv. Nyob rau hauv cov yas nkauj xwb, tsis tau muab ntxiv.
