Polyurethane imitation ntoocov ntaub ntawv tau tsim los ntawm cov kws tshawb fawb German, suav nrog xibfwb Bayer, thiab tau siv dav hauv cov rooj tog kho kom zoo nkauj txij li xyoo 1960s. Tam sim no, nyob rau hauv Tuam Tshoj cov rooj tog zaum thiab woodworking ntau lawm, feem ntau siv imitation ntoo cov ntaub ntawv yog high-density (0.3-0.7g/cm3) polyurethane rigid ua npuas ncauj los yog reinforced rigid ua npuas ncauj imitation ntoo ntaub ntawv, uas belongs rau structural foam plastics. Lawv muaj cov yam ntxwv xws li lub zog siab, zoo toughness, tuab thiab tawv tawv, yooj yim molding txheej txheem, thiab siab ntau lawm efficiency. Nrog rau qhov ntom ntom piv rau cov ntoo ntuj, lawv muaj kev ntxhib los mos zoo sib xws, zoo li, thiab lub zog, ua rau lawv tsim nyog hloov cov ntoo hauv kev tsim cov khoom siv high-end lossis high-strength carved rooj tog thiab cov khoom siv ntoo.
Txhawm rau them nyiaj rau kev ua haujlwm tsis zoo ntawm cov ntaub ntawv polyurethane imitation ntoo, ntau hom kev kos, xws li cov pas ntoo, cov blocks, boards, thiab steel tuav, feem ntau muab tso rau hauv cov pwm. Txij li cov nqi ntawm cov khoom siv polyurethane yog tus nqi siab, thiab tsuas yog cov molding nto ntawm polyurethane imitation ntoo khoom yog yuav tsum tau, kev siv cov embedded qhov chaw yuav txo tau cov nqi ntau lawm. Yog li ntawd, cov tuam ntxhab ntawm polyurethane imitation ntoo tau cog lus tias yuav ua rau kom siv cov khoom siv kos duab tsis muaj kev cuam tshuam rau qhov zoo. Cov khoom siv sib xyaw no tuaj yeem siv los ua cov khoom siv, nrog rau cov khoom siv txhawb nqa thiab cov khoom thauj khoom rau cov rooj tog zaum lossis cov khoom siv ntoo xws li lub rooj zaum thiab cov rooj zaum.
Ntxiv rau nws cov kev ua tau zoo molding, polyurethane imitation ntoo rooj tog muaj nqi zoo dua piv rau cov rooj tog ntoo. Nws tau dhau los ua neeg nyiam nyob hauv cov teb chaws tsim kho thiab thaj chaw xws li Europe thiab Asmeskas. Nyob rau hauv xyoo tas los no, polyurethane imitation ntoo cov ntaub ntawv tau maj mam siv rau cov khoom siv kho kom zoo nkauj, luas, thiab txawm tias cov khoom siv. Nrog nws cov moldability muaj zog, siab zog-rau-qhov hnyav piv, thiab cov nqi qis, polyurethane imitation ntoo cov ntaub ntawv tau txais kev paub dav hauv kev lag luam rooj tog thiab kho kom zoo nkauj. Ntau thiab ntau lub tuam txhab tau pib tsim thiab siv cov khoom tshiab no.
Txawm li cas los xij, tseem muaj qee qhov kev lag luam hauv tsev tsim cov rooj tog polyurethane imitation ntoo, thiab txawm tias tsawg dua nrog qee qhov teev. Feem ntau ntawm lawv yog concentrated nyob rau hauv ntug hiav txwv dej ntawm East thiab South Tuam Tshoj, thiab lawv cov khoom yog mas exported. Txog rau tam sim no, raws li kev txheeb cais tsis tiav, muaj ntau pua lub lag luam hauv Pearl River Delta thiab Yangtze River Delta tsim thiab siv cov khoom siv polyurethane imitation ntoo, thiab cov tuam txhab hauv cheeb tsam Southwest kuj txhawb lawv txoj kev siv.
Nrog rau qhov tsis zoo ntawm cov ntoo ntuj, kev paub txog ib puag ncig, kev ua tau zoo ntawm polyurethane, thiab kev loj hlob sai ntawm kev lag luam polyurethane, daim ntawv thov ntawm polyurethane imitation ntoo cov ntaub ntawv nyob rau hauv cov rooj tog zaum thiab kho kom zoo nkauj kev lag luam yuav txhawb ntxiv.
Yog li ntawd, polyurethane imitation ntoo rooj tog muaj ntau qhov chaw loj hlob nyob rau hauv lub domestic kev ua lag luam, thiab nws txoj kev loj hlob ceev nyob rau hauv Tuam Tshoj yuav maj nrawm.
