Sealing cov hlua ua lub luag haujlwm hauv kev sib khi thiab kev tiv thaiv dej hauv cov yas steel qhov rooj thiab qhov rai, aluminium alloy qhov rooj thiab qhov rai, thiab cov qhov rooj ntoo thiab qhov rai. Sealing strips muaj qhov siab xav tau ntawm cov khoom siv. Firstly, lawv yuav tsum muaj lub zog tensile zoo thiab elasticity, nrog rau qhov kub thiab txias tsis kam thiab kev laus tiv taus. Nyob rau tib lub sijhawm, txhawm rau kom ntseeg tau tias qhov sib ze ntawm qhov sib khi ntawm qhov hlua khi thiab qhov profile, cov ntu ntu ntawm cov hlua khi yuav tsum sib phim nrog cov ntaub ntawv ntawm lub qhov rooj thiab lub qhov rais, thiab feem ntau haum rau dai qhov rooj thiab qhov rooj folding thiab qhov rai.
