PU Foam Material Test

Cov khoom siv: muaj feem xyuam rau cov mos mos polyurethane ua npuas ncauj, tawv polyurethane ua npuas ncauj, ib qho nyuaj PU ua npuas ncauj, siab resilience ua npuas ncauj, qeeb resilience (nco paj rwb), nws tus kheej tawv PU ua npuas ncauj, microcellular ua npuas ncauj thiab lwm yam PU ua npuas ncauj ntaub ntawv thiab cov khoom.

Cov xwm txheej siv tau: rooj tog txaj txaj, lub tsheb sab hauv, lub tsev rwb thaiv tsev, ntim cushioning, cov ntaub ntawv khau, suab nrov thiab kev poob siab, kev tsheb ciav hlau, kev siv hluav taws xob hauv tsev thiab lwm yam.

Cov ntaub ntawv siv tau: polyether thiab polyester PU ua npuas ncauj raw khoom, cov ntaub ntawv sib xyaw, cov khoom ua npuas ncauj, thiab cov khoom sib xyaw.

Cov tsos mob thiab kev soj ntsuam me me: Cov tsos tsis muaj qhov tawg, tawg, hollowing, xim txawv, lossis impurities; Txheeb xyuas qhov sib txawv ntawm qhov sib txawv, qhov ntom ntom, tuab, qhov sib xws, thiab qhov pore qauv.

Lub cev thiab txhua yam khoom: tensile lub zog, elongation ntawm tawg, compressive zog, indentation hardness, rebound tus nqi, compressive mus tas li deformation, tsim kua muag zog, shear zog.

Durability thiab kev ua tau zoo: rov compression qaug zog, seem stability, creep kev ua tau zoo, suab nqus kev ua tau zoo, breathability, cushioning kev ua tau zoo.

Kev tiv thaiv ib puag ncig thiab kev nyab xeeb kev ua haujlwm: formaldehyde emission, VOC emission, tsw theem, txwv tsis pub muaj teeb meem xws li hlau hnyav, dawb TDI, polycyclic aromatic hydrocarbons, thiab lwm yam.

Nplaim retardant kev ua tau zoo: oxygen Performance index, kab rov tav combustion, ntsug combustion, pa luam yeeb ntom, toxic pa luam yeeb nrhiav kom tau raws li cov nplaim retardant yuav tsum tau ntawm lub tsev / tsheb / rooj tog.

Kev tiv thaiv ib puag ncig: huab cua kub laus, siab thiab tsis kub hloov pauv, noo noo thiab kub tsis kam, dej tsis kam, roj tsis kam, acid thiab alkali tsis kam, pwm tsis kam, thiab yellowing kuj.

Cov khoom tshwj xeeb: thermal conductivity (rau rwb thaiv tsev lub hom phiaj), kev nyiam huv thiab kev tiv thaiv kab mob, kev nyab xeeb kev noj zaub mov, kev ua haujlwm hauv tsheb hauv atomization.
