Elastomer yog siv rau roj hmab log tsheb thiab raj rau tsheb, maus taus, tsheb kauj vab thiab tsheb ua si, nyom mowers thiab lwm yam tsheb ua haujlwm, siv, hoses, hnab looj tes, matting, khoom ua si balloons, rubber bands, adhesives thiab mem hluav erasers.
Cov piv txwv elastomers yog dab tsi?
Elastomers yog xoob sib txuas cov polymers. … Piv txwv ntawm elastomers muaj xws li natural rubbers, styrene-butadiene thaiv copolymers, polyisoprene, polybutadiene, ethylene propylene roj hmab, ethylene propylene diene roj hmab, silicone elastomers, fluoroelastomers, polyurethane nitrile roj hmab, thiab.
Cov khoom lag luam twg yog tsim los ntawm elastomers?
Cov khoom siv: Ntau yam khoom siv tau tsim nrog cov ntaub ntawv elastomeric, suav nrog raincoats, sponges thiab txawm mem hluav erasers. Ntau cov ntaub ntawv ruaj khov tsis tau ncab kuj tau ua nrog qee hom elastomer-raws li textile. Khau Taw: Elastomers tau siv dav hauv kev siv khau.
Yuav ua li cas elastomers muab piv txwv Chav Kawm 11?
Cov ntaub ntawv uas tsim tawm yog loj dua qhov kev ntxhov siab, nrog rau qhov txwv ntawm elasticity hu ua elastomers, xws li, rubber, cov ntaub so ntswg elastic ntawm aorta, lub nkoj loj nqa ntshav los ntawm lub plawv. thiab lwm yam. Elastomers tsis muaj ntau yam yas.
Dab tsi yog elastomer dab tsi yog lawv qhov tshwj xeeb?
Elastomers (rubbers) yog tshwj xeeb polymers uas elastic heev. Lawv yogmaj mam hla-txuas thiab amorphous nrog iav hloov kub zoo hauv qab chav tsev kub. … Yog li, elastomers muaj qhov qis Young's modulus thiab elongation siab heev thaum tawg thaum piv nrog lwm cov polymers.
