Cov ntaub ntawv ntawm Elastic Bands

Cov khoom tseem ceeb ntawm cov hlua elastic yog cov roj hmab, uas tuaj yeem muab faib ua ob pawg tseem ceeb: roj hmab ntuj thiab hluavtaws roj hmab.

Cov roj hmab ntuj: Muab los ntawm cov latex ntawm cov ntoo roj hmab, nws muaj lub zog siab, siab elasticity, zoo abrasion tsis kam, thiab roj kuj. Nws yog ib qho tseem ceeb raw khoom rau kev ua elastic bands, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov yuav tsum tau siab zog thiab siab elasticity.

Synthetic rubber: Txiv neej-ua polymer elastomers uas nws cov khoom tuaj yeem hloov kho raws li qhov xav tau tshwj xeeb. Muaj ntau ntau hom roj hmab hluavtaws, suav nrog styrene-butadiene roj hmab (SBR) thiab nitrile roj hmab (NBR), uas tau siv dav hauv kev tsim khoom ntawm ntau yam elastic bands, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov uas yuav tsum tau tshwj xeeb cov khoom (xws li kub tsis kam, roj kuj, thiab acid thiab alkali tsis kam).
