A. Mos Polyurethane Ua Npuas Ncauj (feem ntau hu ua daim txhuam cev): Daim txhuam cev siv rau lub rooj zaum sau yog feem ntau muab faib ua peb pawg: Cov ntawv txhuam hniav yog ib daim txhuam cev uas yog tsim los ntawm cov pa polyether thiab TDI. Nws cov yam ntxwv muaj xws li zoo resilience, softness, thiab breathability; High- daim txhuam cev resilience yog ib daim txhuam cev uas yog tsim los ntawm active polyphosphate thiab TDI, cov yam ntxwv ntawm cov khoom siv zoo heev, zoo elasticity, siab compressive load, nplaim taws retardancy, thiab breathability zoo; Random-Pore sponge yog ib daim txhuam cev nrog qhov pores ntawm qhov sib txawv, zoo li cov seaweed ntuj, uas muaj qhov zoo elasticity thiab cushioning thaum compression thiab rebound.
B. Down Filling: Down li sofa filling muab qhov chaw zaum zoo thiab deformation tsawg tshaj li qhov ntev - siv sijhawm. Nws qhov tsis zoo suav nrog qeeb rov qab thiab tus nqi siab. Nws feem ntau yog siv ua ke nrog daim txhuam cev hauv siab -sofas kawg lossis tsim nyog siv ua cushions.
C. Artificial paj rwb Filling: Artificial paj rwb li sofa filling muab ib tug xis zaum kev, tab sis nws cov neeg kho tshuab zog tsis zoo, thiab nws compressive load yog tsawg, ua rau nws tsuas haum rau cushions. Kev xaiv ntawm lub rooj zaum filling cov ntaub ntawv sib txawv heev nyob ntawm seb hom filling khoom. Feem ntau, cov khoom ntim rau cov ntaub sofa cushions yuav tsum siab tshaj -resilience ua npuas ncauj nrog ib tug ceev ntawm 30 kg / m³ los yog siab dua. Feem ntau cov rooj zaum siv ib daim ua npuas ncauj rau sau, tab sis txoj hauv kev zoo tshaj plaws yog los ua ke siab - ua npuas ncauj resilience nrog cov npuas dej tsis sib xws, nrog rau cov paj rwb los yog hluavtaws, kom muaj kev nplij siab thiab lub neej ntev. Thaum xaiv ib lub rooj zaum, nug txog hom filling. If it's foam, check its density, feel the cushion's rebound under pressure, and assess its comfort while sitting on it.
Rau ua npuas ncauj cushions, lub teb chaws tus qauv yog 25 kg / m³, thiab thoob ntiaj teb tus qauv yog 35 kg / m³. Rau cov qauv hauv qab, lub siab - elasticity serpentine caij nplooj ntoos hlav qauv yog superior rau lub webbing qauv, thiab siab - zoo webbing yog zoo dua li qis - zoo webbing. Tom qab lub sij hawm ntev compression, lub siab - zoo webbing qauv yuav tsum sai sai rebound, rov qab mus rau nws qub zoo yam tsis muaj deformation los yog sagging.
