Hauv cov txheej txheem no, lub luag haujlwm tseem ceeb yog hydrolysis stabilizer. Tsis ntev los no, qhov tseem ceeb ntawmcov tshuaj hydrolysis stabilizersthiab lawv daim ntawv thov hauv ntau yam lag luam tau raug tshawb nrhiav tob heev.

Cov tshuaj hydrolysis stabilizers, ua ib yam tshuaj uas tiv thaiv tau cov tshuaj lom neeg kom tsis txhob lwj hauv dej, yog qhov tseem ceeb heev. Hauv kev lag luam khoom noj thiab tshuaj pleev ib ce, cov tshuaj hydrolysis stabilizers tuaj yeem ua kom cov khoom siv tau ntev dua thiab ua kom cov khoom ruaj khov thiab muaj kev nyab xeeb thaum siv. Tib lub sijhawm, hauv kev lag luam tshuaj, cov tshuaj hydrolysis stabilizers kuj tseem 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. Cov hom hydrolysis stabilizers sib txawv no ua lub luag haujlwm tshwj xeeb hauv cov ntawv thov sib txawv raws li lawv cov qauv tshuaj sib txawv thiab cov khoom.

Nws tsim nyog hais tias cov hydrolysis stabilizers yog siv dav hauv kev lag luam tshuaj pleev ib ce. Los ntawm kev ntxiv cov hydrolysis stabilizer kom tsim nyog, cov tshuaj pleev ib ce tuaj yeem txhim kho lawv qhov ruaj khov thiab muaj peev xwm antioxidant, yog li ua kom lub txee ntev dua thiab txhim kho kev siv. Tib lub sijhawm, hydrolysis stabilizers kuj tseem tuaj yeem sib xyaw nrog lwm cov antioxidants lossis preservatives los ua lub luag haujlwm synergistic hauv tshuaj pleev ib ce, ntxiv txhim kho qhov ruaj khov thiab antiseptic muaj peev xwm ntawm cov khoom.

Nws yog ib qho tseem ceeb uas txawm hais tiascov tshuaj hydrolysis stabilizersua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom zoo thiab ruaj khov, nws tseem yog qhov tsim nyog los tswj qhov ntau ntawm kev siv thaum siv thiab tsis txhob siv lawv rau hauv cov chaw tsis muaj zog xws li lub qhov ncauj thiab qhov muag kom ntseeg tau tias siv tau zoo.

DAIM NTAWV THOV

1. Kev lag luam yas thiab roj hmab

Hauv kev tsim cov khoom yas thiab roj hmab, cov hydrolysis stabilizers ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv hydrolysis los ntawm kev ua rau muaj kev tawg ntawm cov saw hlau molecular thiab kev ua haujlwm poob qis. Piv txwv li, hauv cov khoom yas siv sab nraum zoov, ntxiv cov hydrolysis stabilizers tuaj yeem txhim kho lawv cov dej tsis kam thiab noo noo thiab cua sov tsis kam, thiab ntev lawv lub neej kev pabcuam. Tsis tas li ntawd, cov hydrolysis stabilizers kuj ua lub luag haujlwm tseem ceeb hauv cov ntawv thov xws li tsheb sab hauv thiab sab nraud trims thiab cov khoom siv hluav taws xob.

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.Cov tshuaj hydrolysis stabilizerssiv dav hauv cov tshuaj tua kab thiab tuaj yeem tiv thaiv cov tshuaj tua kab hydrolysis hauv qab acid, alkali, kub thiab lwm yam mob, ua kom ntseeg tau tias cov tshuaj tua kab ruaj khov thiab ua haujlwm tau zoo. Daim ntawv thov no tsis yog tsuas yog txhim kho tus nqi siv tshuaj tua kab, tab sis kuj txo qhov cuam tshuam ntawm cov tshuaj tua kab rau ib puag ncig.

3. Stabaxol series ntawm Rhein Chemie

Cov tshuaj Stabaxol series uas tiv thaiv kev tawg ua rau cov polyurethane elastomers thiab cov thermoplastic polyurethane materials (TPU) uas Rhein Chemie (LANXESS) tsim tawm muab kev tiv thaiv zoo heev rau kev tawg ua rau cov polyurethane elastomers thiab cov thermoplastic polyurethane materials (TPU). Cov tshuaj ua kua tiv thaiv kev tawg ua rau cov polymer polyols yooj yim ntxiv rau hauv kom cov polymer hydrolytically ruaj khov ntev. Hauv lub tshuab nqus dej hauv tsheb, Stabaxol tiv thaiv lub caij nplooj ntoos hlav nqus dej kom tsis txhob raug rhuav tshem ua ntej lub sijhawm vim yog kev tawg ua rau lub cev laus, ua rau lub neej ua haujlwm ntev dua. Tsis tas li ntawd, Stabaxol kuj tseem siv dav hauv cov thermoplastic elastomers hauv kev tsim cov cable, ua rau cov ester-based elastomers tsis muaj zog rau kev tawg ua rau cov hydrolysis tsis zoo.

4. Kev lag luam khoom noj thiab tshuaj pleev ib ce

Cov tshuaj hydrolysis stabilizers kuj siv dav hauv kev lag luam khoom noj thiab tshuaj pleev ib ce. Hauv cov khoom noj, cov tshuaj hydrolysis stabilizers tuaj yeem ua kom cov khoom noj ntev dua thiab tswj tau qhov saj thiab cov txiaj ntsig ntawm cov khoom noj. Hauv cov tshuaj pleev ib ce,cov tshuaj hydrolysis stabilizerstuaj yeem txhim kho qhov ruaj khov thiab lub peev xwm antioxidant ntawm cov tshuaj pleev ib ce, ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov khoom thaum siv.

Hauv kev xaus,Cov tshuaj hydrolysis stabilizers ua lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub no. Nws cov kev siv dav dav tsis yog tsuas yog txhim kho qhov zoo thiab kev ruaj khov ntawm cov khoom, tab sis kuj txhawb nqa kev txhim kho kev lag luam ntsig txog.
