Cov ntaub ntawv kev nyab xeeb ntawm hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) feem ntau suav hais tias muaj kev nyab xeeb rau kev siv ntau yam kev lag luam thiab kev siv thaum tuav thiab siv raws li cov lus pom zoo.Txawm li cas los xij, zoo li txhua yam tshuaj lom neeg, nws tseem ceeb heev uas yuav tsum paub txog nws cov ntaub ntawv kev nyab xeeb, suav nrog kev phom sij, kev ceev faj, thiab cov txheej txheem xwm txheej ceev.Nov yog cov ntsiab lus ntawm cov ntaub ntawv kev nyab xeeb rau hydroxyethyl cellulose:

1. Cov lus piav qhia lub cev: Hydroxyethyl cellulose feem ntau yog xim dawb mus rau dawb, tsis muaj ntxhiab, thiab tsis qab hmoov.Nws yog non-toxic thiab non-irritating rau ntawm daim tawv nqaij thiab ob lub qhov muag nyob rau hauv ib txwm tej yam kev mob ntawm kev siv.
2. Kev txheeb xyuas qhov phom sij: Hydroxyethyl cellulose tsis raug cais raws li kev phom sij raws li thoob ntiaj teb cov tshuaj lom neeg muaj kev phom sij xws li Lub Ntiaj Teb Kev Sib Raug Zoo ntawm Kev faib tawm thiab Kev Sau Npe Tshuaj (GHS).Nws tsis ua rau muaj kev noj qab haus huv lossis ib puag ncig muaj kev phom sij thaum ua haujlwm zoo.
3. Kev phom sij rau kev noj qab haus huv: Hydroxyethyl cellulose yog suav tias yog tsis muaj tshuaj lom yog tias noj me me.Txawm li cas los xij, kev noj ntau ntau tuaj yeem ua rau plab hnyuv tsis xis nyob lossis cuam tshuam.Kev nqus cov plua plav tuaj yeem ua rau ua pa ua pa rau cov tib neeg rhiab heev.Kev sib cuag ntawm qhov muag yuav ua rau mob me me, thaum lub sijhawm ntev lossis rov ua dua ntawm daim tawv nqaij yuav ua rau mob me me lossis ua xua rau qee tus neeg.
4. Kev tuav thiab khaws cia: Hydroxyethyl cellulose yuav tsum tau ua tib zoo saib xyuas kom txo tau cov hmoov av tsawg.Tsis txhob nqus cov plua plav thiab tiv thaiv qhov muag thiab tawv nqaij.Siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) xws li hnab looj tes thiab tsom iav kev nyab xeeb thaum tuav cov hmoov.Khaws hydroxyethyl cellulose nyob rau hauv ib qho chaw txias, qhuav, zoo-ventilated qhov chaw deb ntawm qhov chaw ntawm tshav kub, ignition, thiab incompatible ntaub ntawv.
5. Kev Ntsuas Thaum Muaj Xwm Ceev: Nyob rau hauv rooj plaub ntawm kev noj tsis haum, yaug qhov ncauj kom huv si thiab haus dej kom ntau kom dilute.Nrhiav kev kho mob yog tias muaj tsos mob.Thaum qhov muag pom, yaug qhov muag nrog dej tsawg kawg 15 feeb, tuav daim tawv muag qhib.Tshem cov looj ntsej muag yog tias muaj thiab yaug ntxiv.Nrhiav kev kho mob yog tias khaus khaus tshwm sim.Nyob rau hauv rooj plaub ntawm kev sib cuag ntawm daim tawv nqaij, ntxuav qhov chaw cuam tshuam nrog xab npum thiab dej.Yog tias khaus khaus tshwm sim, nrhiav kev kho mob.
6. Environmental Impact: Hydroxyethyl cellulose yog biodegradable thiab tsis ua rau muaj kev phom sij rau ib puag ncig.Txawm li cas los xij, kev nchuav loj lossis tso tawm rau hauv ib puag ncig yuav tsum tau ntim thiab ntxuav kom sai kom tsis txhob muaj kab mob hauv av, dej, lossis ecosystems.
7. Raws li txoj cai: Hydroxyethyl cellulose yog dav siv nyob rau hauv ntau yam lag luam, nrog rau cov kws kho mob, cov khoom tu tus kheej, zaub mov, thiab cov ntaub ntawv tsim kho.Nws feem ntau lees paub tias muaj kev nyab xeeb (GRAS) rau kev siv hauv cov khoom noj thiab tshuaj siv los ntawm cov cai tswj hwm xws li US Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA).

Nws yog ib qho tseem ceeb uas yuav tau sab laj nrog daim ntawv pov thawj kev nyab xeeb (SDS) thiab cov ntaub ntawv khoom lag luam muab los ntawm cov chaw tsim khoom lossis tus neeg muag khoom rau cov lus pom zoo txog kev nyab xeeb thiab cov lus qhia rau kev tuav, khaws cia, thiab pov tseg ntawm hydroxyethyl cellulose.Tsis tas li ntawd, cov neeg siv yuav tsum ua raws li cov cai siv tau thiab cov kev coj ua zoo tshaj plaws rau kev nyab xeeb ntawm cov tshuaj lom neeg hauv lawv cov kev lag luam.
