Cov yam ntxwv ntawm cov roj hmab bands
Cov roj hmab bands yog ib lo lus dav dav rau cov khoom siv hluav taws xob zoo, cov khoom siv hluav taws xob, cov roj ntsha tau ua rau elastomers {}}
Lub siab elasticity ntawm cov roj hmab bands yog manifested hauv:
Thawj
Nws muaj qhov loj dua ntawm kev tawm tsam loj heev thiab tuaj yeem ncav cuag 700% lossis ntau dua;
Ib xi nkoos
Tom qab deformation, nws tuaj yeem kho nws cov qauv qub thaum lub zog sab nraud raug tshem tawm, thiab deformation yog dej muaj zog heev;
Thib peb
Elastic modulus tshwj xeeb yog tsawg, tsuas yog 105pa. Kuv yuav ua rau muaj kev sib tw loj dua ntawm cov roj hmab band {}}
High elastic deformation tuaj ntawm qhov tseeb tias cov nyiaj hauv nws cov nyiaj ntsuab yog qhov yooj yim rau defination . Cov pob zeb sab nraud yog yooj yim rau sab nraud, cov molecular thermal suab tau yooj yim rov qab thawj zaug deformation cia li, uas yog, hloov hauv kev coj ua ntawm cov roj hmab band ncab txo qis zuj zus thiab ua kom muaj ncab yog qhov siab thiab lub zog yuav txias {}
Txog li cas cov siab ywj pheej ncav cuag, thiab ntawm qhov nrawm thiab cov roj hmab yog li cov roj hmab tau hloov kho kom sai thiab tuaj yeem hloov kho cov roj hmab hloov pauv tau sai rau hauv (tab sis tuaj yeem nthuav dav Nyob rau hauv) boiling benzene, methyl ketone, ethanol-{}}}}} {} {{.
