Ib Daim Ntawv Qhia Txog Cov Kab Mob Intumescent

Cov ntawv nplaum uas muaj cov nplaim hluav taws (intumescent strips) yog cov khoom siv tshwj xeeb uas feem ntau siv rau hauv cov tshuab tiv thaiv hluav taws, tshwj xeeb tshaj yog hauv cov qhov rooj thiab qhov rai, los pab tswj lossis txwv tsis pub hluav taws kis mus. Thaum raug cua sov, cov ntawv nplaum no nthuav dav (intumesce) los kaw cov qhov sib txawv, tiv thaiv kev hla ntawm cov pa luam yeeb, cua sov, thiab nplaim taws. Nov yog phau ntawv qhia kom nkag siab txog cov ntawv nplaum uas muaj cov nplaim hluav taws, lawv lub hom phiaj, thiab lawv siv li cas.

1. Cov Kab Xev Intumescent Yog Dab Tsi?

Cov ntawv nplaum uas muaj cov tshuaj lom neeg thiab cov resins feem ntau yog ua los ntawm kev sib xyaw ua ke ntawm cov tshuaj lom neeg thiab cov resins uas ua rau kub heev. Feem ntau lawv muab tso rau hauv cov qhov rooj, cov qhov rai, thiab lwm qhov chaw qhib ua ib qho kev tiv thaiv hluav taws kub. Thaum raug cua sov lossis nplaim taws (feem ntau siab tshaj 200°C lossis 392°F), cov khoom siv no nthuav dav, puv cov qhov sib txawv thiab kaw cov qhov chaw uas yuav ua rau hluav taws lossis pa luam yeeb hla dhau.

2. Cov Intumescent Strips Ua Haujlwm Li Cas?

Lub luag haujlwm tseem ceeb ntawm cov ntawv nplaum intumescent yog ua haujlwm ua ib daim thaiv hluav taws los ntawm kev o tuaj thaum raug cua sov. Qhov nthuav dav feem ntau yog ntau npaug ntawm qhov loj thawj, tsim cov hluav taws kub uas tiv taus hluav taws heev. Qhov kev ua kom sib khi no thaiv cov pa luam yeeb, cua sov, thiab cov pa lom hla mus, txhim kho kev tiv taus hluav taws ntawm cov qhov rooj, qhov rai, thiab lwm qhov chaw qhib.
