Cov qauv ntawm txoj kev loj hlob ntawm hluavtaws nplaum nyob rau hauv lub ntiaj teb no yog qhov tseem ceeb los ntawm ib puag ncig kev tiv thaiv thiab kev ua haujlwm siab, nrog rau kev tiv thaiv ib puag ncig nruj zuj zus, cov teb chaws tsim muaj zog tsim cov nplaum nplaum dej. Vim muaj kev ua tau zoo tshaj plaws ntawm cov dej hauv polyurethane adhesives, nws yog qhov tshwj xeeb hauv txhua yam dej hauv cov nplaum nplaum, thiab tau txais kev saib xyuas ntau hauv tsev thiab txawv teb chaws nyob rau xyoo tas los no, tshwj xeeb tshaj yog kev txhim kho thiab kev tshawb fawb ntawm cov dej ua haujlwm siab polyurethane adhesives tau dhau los ua kub. lub ntsiab lus.
Waterborne polyurethane resin (PUD) yog ib hom emulsion tsim los ntawm dispersing polyurethane hauv dej, uas muaj qhov zoo ntawm VOC tsawg, tsis muaj ntxhiab tsw, tsis-combustible, zoo heev mechanical zog, yooj yim rau kev khiav lag luam thiab ua. PUD tuaj yeem siv dav hauv cov nplaum, tawv hluavtaws, txheej, inks thiab lwm yam lag luam.
Waterborne polyurethane resin raws li kev siv nplaum, nrog kev ua kom yooj yim, ua kom sov zoo thiab lwm yam ntxwv, tuaj yeem siv rau ntau yam kev sib txuas ntawm cov substrate, dav siv hauv khau kua nplaum, automotive sab hauv kua nplaum, lub tshuab nqus tsev, cov nplaum ua haujlwm thiab lwm yam, U1115H, U1115, U1115L yog ib yam peb anionic waterborne polyurethane dispersions, ntawm uas U1115H yog tshwj xeeb tshaj yog haum rau siab pib thaum tshav kub kub tsis kam daim ntawv thov scenarios, U1115L yog tshwj xeeb tshaj yog haum rau scenarios nrog siab viscosity yuav tsum tau.
Waterborne polyurethane muaj ntau yam ntawm lub cev muaj zog tom qab tsim zaj duab xis, nrog zoo txias kuj, hnyav kuj, zaj duab xis tsim, tortuous kuj, qhuav thiab ntub rub kuj, adhesion thiab lwm yam zoo, yuav siv tau raws li ib tug txheej ntawm ntau yam substrates, dav siv. nyob rau hauv tawv xov tus neeg sawv cev, ntaub txheej, hluavtaws tawv thiab lwm yam teb.
Nyob rau hauv luv luv, vim muaj ntau yam zoo ntawm waterborne polyurethane adhesives, lawv siv tau ua ntau thiab ntau, thiab muaj ntau thiab ntau ntau yam. Raws li kev kwv yees ntawm cov kws tshaj lij, qhov kev thov rau cov nplaum hluavtaws hauv Suav teb muaj kev lag luam dav, thiab cov nplaum polyurethane dej tau kov yeej kev lag luam nrog lawv cov kev ua tau zoo tshaj plaws thiab kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob, thiab lawv cov khoom siv thiab daim ntawv thov tau nthuav dav thiab txhawb nqa. . Ntawm chav kawm, nws cov shortcomings kuj yuav tsum tau daws nyob rau hauv ntau qhov tob. Tuam Tshoj yuav tsom mus rau kev tsim cov dej polyurethane adhesives, thiab yuav qhia cov khoom siv tseem ceeb raws li tus kheej tsim tshuab los tsim "ntsuab" hnyav-raws li, tsis-daj-zoo li tus, kub-resistant thiab high-performance PU adhesives; Tsim cov reactive PU kub yaj nplaum, kev ua haujlwm siab PU cov qauv nplaum thiab cov nqi qis dej ntawm cov polymer polyisocyanate nplaum, kom tag nrho qib ntawm PU nplaum hauv Suav teb tuaj yeem ncav cuag qib siab tam sim no hauv ntiaj teb.
