Nyob rau hauv xyoo tas los no, nrog kev taw qhia ntawm ib puag ncig kev tiv thaiv cov cai thiab kev txhawb nqa ntawm ntau yamtxheejmanufacturers, dejyugcov xim tau raug lees paub los ntawm kev ua lag luam, thiab kev ua haujlwm ntawm ob lub ntsiab lus ntawm cov xim dej tau muab piv rau cov xim ntawm cov roj hauv ntau yam, uas yog sib cais los ntawm kev txhim kho thiab kev siv ntawmdej ntws PUcuring tus neeg sawv cev.
Bogao wbnyob rau hauvPUcuring tus neeg sawv cevPEB-2655-80, flos yog waterborne coatings, waterborne adhesives, waterborne inks, thiab lwm yam.
Nws yogsiv los ua curing tus neeg sawv cev rau cov dej uas muaj ob lub ntsiab lusPUqhov system.
Nws muaj cov yam ntxwv ntawm Xim zaj duab xis kom qhuav sai, zoo heev lub cev thiab tshuaj.
Waterborne PU curing agent muaj ntau pawg isocyanate (- NCO), uas tuaj yeem sib xyaw nrog ntau pawg ua haujlwm xws li hydroxyl, amino thiab carboxyl pawg. Yuav ua li cas tswj cov tshuaj tiv thaiv sab kom zoo thiab npaj cov xim pleev xim rau ob qho tib si nrog kev ua haujlwm zoo yuav tsum xaiv tus neeg saib xyuas dej kom tsim nyog, thiab ua kom paub cov ntsiab lus tseem ceeb ntawm kev tsim qauv thiab kev npaj ua yeeb yaj kiab kom ntxaws.
Daim ntawv thov kev tshawb fawb ntawm waterborne PU curing agent pib thaum kawg ntawm 1980s. Bayer tau nyob rau hauv pem hauv ntej ntawm kev tshawb fawb thiab kev loj hlob, thiab kuj tau pab txhawb rau kev txhawb nqa cov dej kho tus neeg sawv cev thiab cov xim dej. Nws pib lig nyob rau hauv Suav teb, tab sis tau tsim sai heev, thiab yog dav siv nyob rau hauv industrial coatings, floor coatings, wood coatings, automotive kev lag luam, textile kev lag luam thiab lwm yam teb.
- Daim ntawv thov nyob rau hauv industrial coatings
Waterborne PU curing tus neeg sawv cev yog txuam nrog dej-dej hydroxyl dispersion resin. Vim tias cov discroxyl dispersion muaj me me molecular hnyav, siab hydroxyl tus nqi thiab tsis muaj surfactive, nws muaj qhov zoo nkauj thiab zoo tsis kam tom qab crosslinking thiab kho. Nws tuaj yeem sib piv rau cov roj-raws li txheej hauv kev ua tau zoo, thiab tuaj yeem siv dav hauv kev lag luam los tiv thaiv corrosion thiab kho kom zoo nkauj txheej.
- Kev siv hauv pem teb txheej
Ob chav dej PUtxheej yog siv rau cov dej hauv pem teb, uas muaj cov yam ntxwv ntawm kev tiv thaiv ib puag ncig thiab kev noj qab haus huv. Cov dej ntwsPUtxheej muaj cov yam ntxwv ntawm kev ua haujlwm siab, hnav tsis kam, huab cua tsis kam, dej tsis kam thiab zoo khawb tsis kam.
- Daim ntawv thov hauv Wood Coatings
High-quality waterborne matte wood xim yog ib qho kev taw qhia ntawm kev lag luam rooj tog. Cov xim zaj duab xis muab qhov zoo nkauj zoo nkauj tom qab kev ploj tuag, thiab nrov heev nrog tib neeg. Cov kua roj vanish txheej ntxiv nrog tus neeg sawv cev matting muaj qhov tsis pom tseeb thiab tsis zoo rau nruab nrab. Cov nyhuv matting tuaj yeem ua tiav los ntawm tus neeg sawv cev kho los ntawm cov qauv molecular. Tib hom xim dej, nrog cov qauv sib txawv ntawm matte curing tus neeg saib xyuas, tuaj yeem tau txais cov gloss peb xav tau.
