Sijhawm: 2024-02-05 Ntaus: 23

Qhov nce ntawm kev txhawj xeeb tshaj cov tshuaj fluorinated 

Zaj movie "Tsaus Dej"hais txog zaj dab neeg ntawm tus kws lij choj Asmeskas uas tau foob ib puag ncig tiv thaiv lub tuam txhab tshuaj lom neeg uas nws tau ua haujlwm ib zaug, pib tshawb nrhiav thiab tawm tsam lub tuam txhab.'Kev npau suav phem tshaj plaws," luam tawm nyob rau hauv New York Times. Qhov kev foob feem ntau yog nyob ib ncig ntawm kaum xyoo ntawm DuPont qhov kev tsim khoom thiab siv cov Perfluorooctanoic acid (PFOA), thiab kev txhawj xeeb ib puag ncig nws tau ua rau.

Raws li zaj dab neeg tau nthuav dav, lo lus tshuaj nyob rau hauv zaj dab neeg, "PFOA," tau dhau los ua neeg paub. PFOA sawv cev rau Perfluorooctanoic Acid, uas yog ib qho surfactant dav siv hauv cov txheej txheem tsim cov fluoroplastics vim nws cov khoom zoo heev. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhawm rau txhawm rau tawg ntawm fluoroplastics xws li polytetrafluoroethylene (PTFE). Txawm li cas los xij, nyob rau xyoo tas los no, kev nyab xeeb ntawm cov tshuaj no tau raug nug ntau.

 

Kev nyab xeeb ntawm cov tshuaj feem ntau raug soj ntsuam thiab tshuaj xyuas los ntawm ntau qhov ntev, feem ntau luv luv hauv kev lag luam li PBT, uas sawv cev rau Persistent, Bio-accumulative, thiab Toxicity. Cov ntsiab lus no sawv cev rau ib puag ncig persistence, biological accumululation, thiab toxicity, feem. Rau peb tus cwj pwm ntawm PFOA, kev tshawb fawb dav tau ua, nthuav tawm nws cov yam ntxwv P thiab B. Thaum nws tus yam ntxwv T tsis tau lees paub tag nrho, nws tau ua rau muaj kev txhawj xeeb thoob plaws, ua rau muaj kev lag luam thoob plaws hauv pawg thawj coj los pib nthwv dej ntawm phasing tawm PFOA.

PFAS thiab Environmental Regulation 

Nyob rau hauv xyoo tas los no, raws li theem-tawm ntawm PFOA tau nrawm dua, lwm lo lus tshuaj,PFAS, tau dhau los ua lub ntsiab lus kub. PFAS sawv cev rau cov tshuaj per- thiab polyfluoroalkyl. Cov tshuaj polyfluoroalkyl, uas suav nrog ntau qhov sib txawv ntawm cov tshuaj fluorinated, xws li PFOA, PFOS, PFHxA, PFHxS, thiab lwm yam, txhua tus yog PFAS. Cov pawg no suav nrog ntau dua 4,700 fluorinated compounds, suav nrog yuav luag txhua yam khoom muaj fluorine hauv kev lag luam tshuaj. Lub ntsiab yog vim li cas vim li cas cov tshuaj no tau attracted xim yog lawv exceptional stability; lawv tsis yooj yim degraded nyob rau hauv ib puag ncig thiab feem ntau pom cov khoom tsis tu ncua. Yog li ntawd, kev txhawj xeeb tshwm sim txog lawv qhov chaw nyob ib puag ncig mus sij hawm ntev thiab tsub zuj zuj vim lawv qhov kev pheej hmoo.

Fluorides tau siv dav hauv peb lub neej niaj hnub, nrog rau ib qho piv txwv paub yog polytetrafluoroethylene, feem ntau hu ua "yas huab tais." Nws plays lub luag haujlwm tseem ceeb hauv kev lag luam thiab hauv tsev. Piv txwv li, tsis yog-stick cookware, ib lub tsev staple, yog coated nrog ib txheej ntawm polytetrafluoroethylene, muab nws cov khoom tsis-stick. Ib yam li ntawd, textiles underwater waterproof, oil-proof, thiab stain-resistant kev kho mob, feem ntau hu ua "peb-proof finishing," siv fluorides los kho cov ntaub. Hauv kev lag luam ntim khoom noj, fluorides kuj yog emplam mus kho ntawv rau ntim cov zaub mov oily, muab cov khoom tsis muaj dej thiab roj-resistant.


Vim muaj kev txhawj xeeb thoob plaws PFAS, European Union tau ua tus thawj coj hauv kev hais txog qhov teeb meem. Thaum Lub Peb Hlis 2023, European Chemicals Agency (ECHA) tau pib muaj kev sib tham rau pej xeem txog cov lus pom zoo xa los ntawm Denmark, Lub Tebchaws Yelemees, Netherlands, Norway, thiab Sweden txhawm rau ntxiv kev txwv rau kev tsim khoom, tso rau hauv kev ua lag luam, thiab siv PFAS rau Annex XVII ntawm REACH (Kev Sau Npe, Kev Ntsuam Xyuas, Kev Tso Cai thiab Kev Txwv Cov Tshuaj). Lub hom phiaj yog los tso cai rau cov neeg koom nrog los qhia lawv cov kev xav txog suav nrog PFAS hauv REACH txwv thiab kev tswj hwm. Tom qab qhov xaus ntawm kev sib tham rau pej xeem, ECHA's Risk Assessment Committee (RAC) thiab Socio-Economic Analysis Committee (SEAC) yuav ntsuam xyuas cov kev txwv uas tau hais tseg raws li kev sib tham tawm tswv yim. Qhov kev txiav txim zaum kawg ntawm seb puas suav nrog PFAS hauv kev txwv thiab kev tswj hwm yuav ua los ntawm European Commission.

Kev cuam tshuam rau Traditional Fluorine Chemical Companies

Cov tuam txhab tshuaj fluorine ib txwm muaj xws li DuPont, 3M, thiab Daikin, uas tau nyob ib puag ncig ntau pua xyoo, tab tom ntsib kev nyuaj siab heev. Xyoo 2022, 3M tau tshaj tawm txog $ 10.3 nphom kev sib hais kom them rau 13 xyoo tom ntej no (kwv yees li 74 billion RMB) thiab npaj yuav tawm hauv kev lag luam tshuaj fluorine los ntawm 2025. Ib yam li ntawd, DuPont tau pom zoo them $ 670 lab kev daws teeb meem hauv ib puag ncig ntev. foob ​​thiab tawm ntawm kev lag luam tshuaj fluorine hauv qee thaj chaw. Cov kev nqis tes ua los ntawm cov koom haum thoob ntiaj teb no qhia txog kev txhawj xeeb txog cov tshuaj fluorides hauv zej zog.

 

Pulp molded cov khoom, feem ntau hu ua ntawv tableware, tau nrov nrov thiab tsim nyob rau hauv xyoo tas los no vim lawv txoj kev nyiam huv thiab yooj yim degradability.Cov tshuaj tua kab mob fluoride Feem ntau yog siv los ua cov khoom siv ntxiv rau kev faib cov dej tsis zoo thiab cov roj pov thawj rau cov ntawv tais diav. Txawm hais tias cov tshuaj fluoride tau ua tiav zoo rau kev kho cov ntawv tais diav, kev txhawj xeeb txog PFAS thoob ntiaj teb yuav ua rau nws tshem tawm ntawm daim ntawv thov khoom. Piv txwv li, US FDA tau tshaj tawm hauv nws lub vev xaib official tias txij Lub Ib Hlis 1, 2024, fluorides teev nyob rau hauv FCN rau kev kho cov ntawv roj-resistant yuav raug txiav tawm ntawm lub khw.

Taw qhia txog cov khoom tsis muaj fluorinated roj-Resistant 

Nws yog ob qho kev sib tw thiab lub sijhawm. Thaum cov tuam txhab loj tab tom txiav tawm cov tshuaj fluorinated, lawv tab tom nrhiav lwm txoj hauv kev. Rau cov tshuaj tiv thaiv roj siv hauv kev ua cov ntawv, cov khoom siv tshiab yuav tsum tau ua kom tau raws li ntau qhov kev xav tau: ua ntej, lawv yuav tsum tsis muaj fluorine; Thib ob, lawv yuav tsum ua tau zoo hauv cov dej tsis zoo thiab cov roj-resistant, tshwj xeeb tshaj yog tiv thaiv cov roj kub thiab txias; Thib peb, lawv yuav tsum tau siv tau raws li kev ua haujlwm uas twb muaj lawm.


Tam sim no, qee lub tuam txhab tau qhia cov khoom uas tsis yog fluorinated roj-resistant mus rau lub khw. Piv nrog rau cov tshuaj fluorinated roj ib txwm muaj, lawv qhov kev ua tau zoo sib txawv. Zuag qhia tag nrho, lawv tuaj yeem piav qhia tias "translucent tab sis tsis pob tshab." Piv txwv li, nyob rau hauv cov roj kuj ntsuas rau daim ntawv tableware, ncuav kub roj ntawm 85°C rau hauv ib lub tais los yog phaj thiab tuav nws li 30 feeb yam tsis muaj xim los yog xau yog suav tias tsim nyog. Cov tshuaj fluorinated cov tshuaj kho tau yooj yim tuaj yeem ua tiav qhov no, tab sis tam sim no cov roj uas tsis muaj tshuaj fluorinated yuav ua rau tsis muaj xim sai sai tom qab cov roj nchuav rau ntawm lawv. Txawm hais tias lawv yuav tsis xau raws li qee qhov xwm txheej tom qab 30 feeb, lawv qhov kev ua tau zoo tsis tuaj yeem suav tias yog qhov txaus siab. Ntxiv mus, ib zaug cov roj kub siab tshaj qhov pib, xws li 60°C, leakage tshwm sim tam sim ntawd, thiab lawv tsis tuaj yeem tiv thaiv cov roj permeation ntawm lub tub yees txias. Cov khoom no tseem tsis tuaj yeem ua tau raws li qhov ua tau zoo ntawm cov roj fluorinated thawj zaug, qhia txog kev sib tw loj heev uas cuam tshuam.

Chem-Plus: Hais Txog Kev Sib Tw Ua Haujlwm

Chem-Plus khoom daws qhov teeb meem no tau zoo, ua tau raws li peb qhov kev thov loj. Ua ntej, nws tsis muaj fluoride. Ob qho tib si cov khoom nws tus kheej thiab cov tais diav ua nrog Chem-Plus roj-repellent cov neeg ua haujlwm tau dhau qhov kev sim los ntawm qhov chaw kuaj pom zoo,kom ntseeg tau tias tsis muaj fluoride tag.

 

Qhov thib ob yog tias qhov kev ntsuam xyuas cov roj ua tau zoo ua tau raws li qhov yuav tsum tau ua. Nyob rau hauv ib txoj hauj lwm ua nyob rau hauv kev lag luam, peb cov khoom siv ntau qhov kev faib tawm los tiv thaiv cov roj tuaj yeem ua tiav cov roj ruaj khov ntawm qhov kub ntawm 20-70.°C. Cov thev naus laus zis tau paub tab, thiab tam sim no, cov khoom tuab tuaj yeem ncav cuag 0.5-0.6mm.

Thirdly, nws tuaj yeem ua tau zoo nrog cov txheej txheem uas twb muaj lawm. Cov khoom Chem-Plus twb dhau qhov kev lees paub ntawm cov tshuab loj, nrog cov txheej txheem ruaj khov thiab ua tau zoo heev.

 

zoo oleophobic roj repellent


Chem-Plus oil-resistant agents pioneered loj zus tau tej cov fluorine-dawb roj-tiv taus tus neeg sawv cev rau kev siv nyob rau hauv lub domestic thiab txawv teb chaws. Siv Chem-Plus roj repellent, tshiab hom ntawv tableware tiv taus kub txog 100 degrees Celsius tau tsim thiab maj mam lees paub los ntawm cov neeg siv khoom. Thov kom cov tiam tshiab ntawm cov khoom tsis muaj fluorine hais txog kev lag luam xav tau thiab ua tau raws li cov neeg siv khoom xav tau.
