Specification
Lub teeb Stabilizer LS 119 (tseem hu ua Lub Teeb Stabilizer 119, Chimassorb 119) yog ib qho tsis yog -polymeric siab molecular hnyav hindered amine teeb stabilizer (HALS). Raws li qhov thib peb - tiam HALS cov khoom lag luam, nws lub npe tshuaj yog cov polymer complex ntawm 1,3,5-triazine-2,4,6-triamine, nrog rau qhov hnyav molecular txog 2285.61 g / mol. Cov qauv no endows nws nrog ob qho tib si tsis tshua muaj volatility thiab tsiv teb tsaws tsis kam ntawm siab molecular hnyav HALS, thaum tseem muaj cov cim acid tsis kam.

Nta
LS119 tuaj yeem txhim kho cov xim ntawm cov khoom siv xim polyolefin.Vim nws cov qauv macromolecular, nws yog qhov tsim nyog rau txhua qhov chaw uas yuav tsum muaj qhov tsis muaj zog thiab muaj zog tiv thaiv kev tsiv teb tsaws.
LS 119 nthuav tawm cov teebmeem tseem ceeb thaum siv ua ke nrog ntau lub teeb stabilizers thiab UV absorbers:
Siv ua ke nrog qhov hnyav molecular HALS:Xws li LS 770, UV 3853
Siv ua ke nrog lwm qhov hnyav molecular hnyav HALS:Tshwj xeeb nrog LS 622, ua kom muaj kev sib koom ua ke
Siv ua ke nrog UV absorbers:Thaum siv nrog UV absorbers tsim nyog, nws muab kev tiv thaiv zoo heev tiv thaiv cov teeb meem xws li gloss, tawg, blistering, delamination, thiab discoloration.
Kev ntsuas kev ua tau zoo:Thaum siv nrog cov stabilizers tsim nyog, nws tuaj yeem tiv thaiv cov teeb meem xws li yellowing, gloss poob, tawg, thiab chalking.
Daim ntawv thov
Lub teeb Stabilizer LS 119 muaj txiaj ntsig zoo rau lub teeb stabilization ntawm polyolefins, tshwj xeeb tshaj yog polypropylene fibers thiab polyethylene-raws li cov yeeb yaj kiab ua liaj ua teb.
Nws kuj tseem siv tau rau lub teeb stabilization ntawm styrenic polymers (ABS, ASA), polyamides (tshwj xeeb fibers), thermoplastic polyurethanes (TPU), polyacetal, thiab hmoov txheej.

Kev ua haujlwm thiab kev tiv thaiv
Yuav tsum tau ua raws li kev coj ua chemical. Tsis txhob tiv tauj tsis tsim nyog:
Hnav khaub ncaws thiab hnab looj tes tiv thaiv tsim nyog thaum ua haujlwm
Tiv thaiv kom tsis txhob nqus plua plav thiab ua kom muaj cua zoo hauv chaw ua haujlwm
Nyob rau hauv rooj plaub ntawm daim tawv nqaij, ntxuav nrog xab npum thiab dej; Thaum ntsib qhov muag, yaug tam sim ntawd nrog dej kom ntau thiab nrhiav kev kho mob
Cov ntaub ntawv ecological
Cov khoom no muaj tshuaj lom rau cov kab mob hauv dej thiab tuaj yeem ua rau muaj kev cuam tshuam ntev - nyob rau hauv ib puag ncig dej. Tsis txhob tso tawm rau ib puag ncig.
Kev tswj hwm xwm txheej
Ua raws li kev ntsuas kev nyab xeeb ntawm tshuaj lom neeg. Thov xa mus rau Daim Ntawv Qhia Kev Nyab Xeeb (MSDS) kom paub meej
Muaj qhov zoo tshwj xeeb hauv kev siv hmoov txheej
