Nrog kev txhim kho txuas ntxiv ntawm kev lag luam niaj hnub thiab thev naus laus zis, kev siv tshuaj lom neeg hauv kev tsim khoom txhua hnub thiab lub neej tau dhau los ua ntau thiab ntau dua. Hauv cov txheej txheem no, lub luag haujlwm tseem ceeb yog hydrolysis stabilizer. Tsis ntev los no, qhov tseem ceeb ntawmhydrolysis stabilizersthiab lawv daim ntawv thov nyob rau hauv ntau yam kev lag luam tau tshawb nrhiav tob heev.

Hydrolysis stabilizers, uas yog ib qho tshuaj tua kab mob uas tuaj yeem tiv thaiv cov tshuaj lom neeg los ntawm kev decomposing hauv dej, yog qhov tseem ceeb ntawm tus kheej. Hauv kev lag luam khoom noj khoom haus thiab tshuaj pleev ib ce, hydrolysis stabilizers tuaj yeem txuas lub neej txee ntawm cov khoom thiab xyuas kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov khoom thaum siv. Nyob rau tib lub sijhawm, hauv kev lag luam tshuaj, hydrolysis stabilizers kuj ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov tshuaj los ntawm hydrolysis.

Nws tau taw qhia tias muaj ntau hom hydrolysis stabilizers, suav nrog phenolic antioxidants, phosphate antioxidants, alcoholamine antioxidants, thiab lwm yam.

Nws yog tsim nyog hais tias hydrolysis stabilizers tshwj xeeb tshaj yog siv dav hauv kev lag luam tshuaj pleev ib ce. Los ntawm kev ntxiv qhov tsim nyog ntawm hydrolysis stabilizer, tshuaj pleev ib ce tuaj yeem txhim kho lawv cov kev ruaj khov thiab muaj peev xwm antioxidant, yog li txuas lub txee lub neej thiab txhim kho kev siv. Nyob rau tib lub sijhawm, hydrolysis stabilizers kuj tuaj yeem sib xyaw nrog lwm cov tshuaj tiv thaiv antioxidants los yog cov tshuaj tua kab mob los ua lub luag haujlwm sib koom ua ke hauv cov tshuaj pleev ib ce, ntxiv dag zog rau kev ruaj ntseg thiab tshuaj tua kab mob ntawm cov khoom.

Nws yog tseem ceeb hais tias txawmhydrolysis stabilizersua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom lag luam zoo thiab kev ruaj ntseg, nws tseem yuav tsum tau tswj cov khoom siv thaum siv thiab tsis txhob siv rau hauv qhov chaw tsis zoo xws li lub qhov ncauj thiab qhov muag kom ruaj ntseg siv.

APPLICATION

1. Kev lag luam yas thiab roj hmab

Hauv kev tsim cov khoom yas thiab roj hmab, hydrolysis stabilizers ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv hydrolysis los ntawm kev ua rau cov saw hlau molecular tawg thiab kev ua haujlwm tsis zoo. Piv txwv li, hauv cov khoom siv yas siv sab nraum zoov, ntxiv hydrolysis stabilizers tuaj yeem txhim kho lawv cov dej tsis kam thiab ya raws thiab cua sov, thiab txuas ntxiv lawv lub neej kev pab cuam. Tsis tas li ntawd, hydrolysis stabilizers tseem ua lub luag haujlwm tseem ceeb hauv kev siv xws li tsheb sab hauv thiab sab nrauv thiab cov khoom siv hluav taws xob hauv tsev.

2. Kev lag luam tshuaj tua kab

Cov khoom xyaw tseem ceeb ntawm cov tshuaj tua kab feem ntau yooj yim hydrolyzed thiab poob lawv cov haujlwm.Hydrolysis stabilizersyog siv dav hauv cov tshuaj tua kab thiab tuaj yeem tiv thaiv cov tshuaj tiv thaiv hydrolysis ntawm cov tshuaj tua kab nyob rau hauv acid, alkali, kub thiab lwm yam kev mob, kom ntseeg tau cov kav ntev thiab kev ua tau zoo ntawm cov tshuaj tua kab. Daim ntawv thov no tsis tsuas yog txhim kho kev siv cov tshuaj tua kab, tab sis kuj txo cov kev cuam tshuam ntawm cov tshuaj tua kab rau ib puag ncig.

3. Stabaxol series ntawm Rhein Chemie

Lub anti-hydrolysis stabilizer Stabaxol series launched los ntawm Rhein Chemie (LANXESS) muab kev tiv thaiv hydrolysis zoo heev rau polyurethane elastomers thiab thermoplastic polyurethane cov ntaub ntawv (TPU). Cov kua dej los tiv thaiv hydrolysis xws li Stabaxol P 200 tuaj yeem yooj yim ntxiv rau polymer polyols kom cov polymer hydrolytically ruaj khov rau lub sijhawm ntev. Nyob rau hauv lub automotive shock absorption system, Stabaxol tiv thaiv lub auxiliary shock absorption caij nplooj ntoos hlav los ntawm scrapped ntxov ntxov vim hydrolysis aging, ncua kev pab cuam lub neej. Tsis tas li ntawd, Stabaxol kuj tau siv dav hauv cov thermoplastic elastomers hauv cov khoom siv cable, ua rau tsis muaj zog ntawm ester-based elastomers rau hydrolysis.

4. Kev lag luam zaub mov thiab tshuaj pleev ib ce

Hydrolysis stabilizers kuj tau siv dav hauv kev lag luam khoom noj thiab tshuaj pleev ib ce. Hauv cov zaub mov, hydrolysis stabilizers tuaj yeem txuas ntxiv lub neej txee ntawm cov zaub mov thiab tswj cov saj thiab kev noj haus ntawm cov zaub mov. Hauv tshuaj pleev ib ce,hydrolysis stabilizerstuaj yeem txhim kho kev ruaj ntseg thiab muaj peev xwm antioxidant ntawm cov tshuaj pleev ib ce, ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm cov khoom thaum siv.

Hauv cov ntsiab lus,Hydrolysis stabilizers ua lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub no. Nws cov kev siv ntau yam tsis yog tsuas yog txhim kho qhov zoo thiab ruaj khov ntawm cov khoom, tab sis kuj txhawb txoj kev loj hlob ntawm cov lag luam uas muaj feem xyuam nrog.
