Flexible polyurethane ua npuas ncauj (FPF) yog ib qho polymer uas tsim los ntawm cov tshuaj tiv thaiv ntawm polyols thiab isocyanates, cov txheej txheem tshuaj pioneered hauv xyoo 1937. FPF yog tus cwj pwm los ntawm cov qauv cellular uas tso cai rau qee qhov kev sib tw thiab kev ua haujlwm siab uas muab cov nyhuv cushioning.Vim tias cov cuab yeej no, nws yog cov khoom siv hauv cov rooj tog zaum, txaj, rooj zaum hauv tsheb, khoom siv kis las, ntim khoom, khau, thiab ntaub pua plag cushion.Nws kuj plays lub luag haujlwm tseem ceeb hauv soundproofing thiab pom.

Ua npuas ncauj yog feem ntau tsim nyob rau hauv loj buns hu ua slabstock, uas tau tso cai rau kho rau hauv ib tug ruaj khov cov ntaub ntawv thiab ces txiav thiab zoo li tus me me daim nyob rau hauv ntau qhov ntau thiab tsawg thiab configurations.Cov txheej txheem ntau lawm slabstock feem ntau piv rau cov qhob cij nce—Cov tshuaj ua kua yog nchuav rau hauv txoj siv conveyor, thiab lawv tam sim ntawd pib foaming thiab nce mus rau hauv ib lub pob loj (feem ntau txog plaub taw siab) thaum lawv mus rau hauv lub conveyor.

Cov ntaub ntawv nyoos yooj yim rau FPF feem ntau ua tiav nrog cov khoom ntxiv uas ua rau cov khoom xav tau.Cov no muaj ntau yam los ntawm kev nplij siab thiab kev txhawb nqa uas xav tau rau cov rooj zaum upholstered mus rau qhov kev poob siab-nqus tau siv los tiv thaiv cov khoom ntim, mus rau lub sij hawm ntev kev puas tsuaj los ntawm cov ntaub pua plag cushion.

Amine catalysts thiab surfactants tuaj yeem sib txawv qhov loj ntawm cov hlwb tsim thaum lub sij hawm cov tshuaj tiv thaiv ntawm polyols thiab isocyanates, thiab yog li sib txawv ua npuas ncauj zog.Cov khoom siv ntxiv tuaj yeem suav nrog cov nplaim hluav taws xob siv rau hauv dav hlau thiab tsheb thiab cov tshuaj tiv thaiv kab mob los tiv thaiv pwm hauv kev siv sab nraum zoov thiab hauv hiav txwv.
