Txoj Cai Elastic Ntawm Rubber Xov

Rubber xov, tseem hu ua elastic band xov, yog ib qho khoom siv nrog lub hauv paus ntawm ntuj lossis hluavtaws roj hmab thiab txheej txheej ntawm woven fiber.

Vim nws zoo heev resilience thiab tensile lub zog, nws yog dav siv nyob rau hauv elastic qhov chaw ntawm cov khaub ncaws xws li ris tsho hauv qab, ncaws pob ris, thiab siv.

Nws elasticity los ntawm kev ncab thiab kev cog lus ntawm lub hauv paus roj hmab molecular chains. Thaum raug rau sab nraud quab yuam, nws tuaj yeem txuas tau sai thiab rov qab mus rau nws qhov qub qub tom qab tso tawm, thiab nws tsis yooj yim loosen nrog ntev - siv sijhawm.
