TIAB SA 770

HALS 770 yog ib qho kev ua haujlwm siab hindered amine teeb stabilizer uas tau siv dav hauv ntau daim ntawv thov polyolefin. Cov khoom no muaj ob peb yam txiaj ntsig uas ua rau nws sawv hauv kev ua lag luam.

Ua ntej thiab qhov tseem ceeb tshaj plaws, HALS 770 muaj qhov tshwj xeeb tiv thaiv UV. Nws tuaj yeem nqus cov teeb meem UV rays thiab tiv thaiv lawv los ntawm kev cuam tshuam nrog cov saw hlau polymer, uas ua rau huab cua zoo dua ntawm cov khoom kawg. Qhov zoo no ua kom ntseeg tau tias cov khoom lag luam polyolefin khaws nws cov xim thiab lub zog txawm tias tom qab raug tshav ntuj ntev.

Lwm qhov txiaj ntsig tseem ceeb ntawm kev siv HALS 770 yog nws qhov kub thiab txias. Nws tseem nyob ruaj khov ntawm qhov kub txog li 200 degree, uas ua rau nws haum rau siv hauv thermal ua daim ntaub ntawv. Yog li ntawd, nws ua kom ntseeg tau tias cov khoom lag luam polyolefin khaws nws cov duab thiab kev ncaj ncees txawm tias qhov kub thiab txias.

Ntxiv mus, HALS 770 yog tshuaj ruaj khov thiab tsis hnov ​​​​mob nrog lwm cov tshuaj hauv polyolefin. Cov cuab yeej no pab tiv thaiv kom tsis txhob degradation ntawm cov polymer thiab ua kom ruaj khov ntawm nws cov khoom siv kho tshuab thiab lub cev lub sijhawm.

Hauv kev xaus, HALS 770 yog qhov ua tau zoo, txhim khu kev qha, thiab ntau yam ntxiv uas coj tau cov txiaj ntsig zoo rau cov ntawv thov polyolefin. Nws cov khoom tiv thaiv UV, qhov kub thiab txias, thiab tshuaj tiv thaiv ua rau nws sawv hauv kev lag luam, kom ntseeg tau tias cov khoom kawg zoo li thiab ua tau zoo tshaj plaws.
