Roj pov thawj tus neeg muag khoom: Qhov twg yuav nrhiav tau qhov zoo tshaj plaws?

Sijhawm: 2024-02-23 Ntaus: 27

Raws li lub Ob Hlis 2024, cov tuam txhab loj ntawm cov ntawv luam tawm roj tau tso tseg kev tsim khoom thiab muag cov khoom lag luam fluorine-muaj cov roj pleev cov khoom, qhia txog kev tawm ntawm cov khoom siv tshuaj fluorinated los ntawm cov ntawv luam tawm roj. Ntawm no juncture, tsab xov xwm no aims los tshuaj xyuas keeb kwm ntawm cov roj repellent cov khoom uas tsim los ntawm cov tuam txhab loj, ua ib tug siv rau lub lag luam yav tom ntej.

 

Cov txheej txheem thaum ntxov rau roj kuj:

Roj-Cov ntawv pov thawj tau tsim thaum ntxov li xyoo 1896, vim tias daim ntawv ib txwm tsis tuaj yeem tiv taus roj. Txhawm rau kom ua tiav cov roj ua haujlwm, ntau cov txheej txheem feem ntau yog ua haujlwm. Qhov no suav nrog hnyav calendering kom nce daim ntawv ceev thiab siv ib txheej ntawm wax (stearic acid) rau ntawm daim ntawv. Qee zaum, kev kho sulfuric acid kuj tseem siv los tiv thaiv cov roj nkag mus. Txawm li cas los xij, cov txheej txheem no tsis zoo tag nrho, vim tias cov roj tseem tuaj yeem nkag mus.

3M's Pioneering Siv Cov Tshuaj Fluorinated:

3M Co.rporation yog tus pioneer ntawm fluorinated ntawv roj repellent.Raws li thaum ntxov li 1980s, 3M tau tsim thiab qhia cov ntaub ntawv roj repellent rau kev ua lag luam, raws li lub hauv paus ntsiab lus ntawm technologies sib txawv kiag li. Leveraging cov khoom ntawm fluorine los txo qhov nro, cov kev kho mob no txo ​​qhov nro ntawm daim ntawv mus rau ib ncig ntawm 20, imparting roj kuj rau daim ntawv. Tsis tas li ntawd, lawv txoj kev ntsuas qhov nro-raws li kev sim, Cov Khoom Siv Xeem, tau dhau los ua tus qauv rau American Pulp thiab Paper Industry (TAPPI).

Ua ntej xyoo 2000, 3M Corporation tau tuav cov ntawv pov thawj rojt nrog tshaj 80% kev ua lag luam. Lawv muab ntau yam khoom qauv, suav nrog FC-805, FC-807, FC-809, FC-845, FC-850, FC-886, thiab lwm yam. Txawm li cas los xij, nyob ib ncig ntawm xyoo 2000, vim muaj kev txhawj xeeb txog perfluorooctane sulfonate (PFOS) tsim nyob rau hauv cov txheej txheem electrochemical fluorination (ECF), 3M proactively thim tawm ntawm kev ua lag luam.

 

Kev sib tw thiab kev tsim kho tshiab:

Tsis zoo li 3M Corporation cov txheej txheem ECF, cov tuam txhab tshuaj fluorinated xws li Dupont feem ntau siv cov txheej txheem telomerization, uas tsis tsim cov khoom nruab nrab PFOS. Yog li ntawd, kev ua lag luam nkag mus rau lub sijhawm ntawm kev sib tw hnyav ntawm ntau tus players. Dupont tau qhia nwsoil-resistant khoom cov qauv, suav nrog Zonyl ™ NF, Zonyl ™ 8868, Zonyl ™ 9464, thiab lwm yam.

 

Atofina, lub tuam txhab Fab Kis, tau qhia txog cov khoom siv roj-repellent Forapele ™ 321 thiab Forapele ™ 325, uas tau txais lub koob npe nrov hauv kev ua lag luam. Tshwj xeeb tshaj yog, F-321, lub hnub qub khoom nyob rau hauv Suav pulp molding kev lag luam, nteg lub hauv paus rau txoj kev loj hlob thiab kev lag luam qauv ntawm daim ntawv molding sector. Cov khoom lag luam tau ua lub luag haujlwm tseem ceeb hauv kev tsim cov qauv kev lag luam uas tau hais hauv GB18006.1-1999 rau cov khoom siv biodegradable pov tseg, tshwj xeeb tshaj yog cov qauv roj kub-resistant.

 

Kev txhim kho thaum ntxov ntawm kev lag luam ntim ntawv-yas yog feem ntau tau tsav los ntawm phasing tawm ntawm cov npuas dej dawb hauv txoj kev tsheb ciav hlau. Cov khoom no tau txais lub zog nrog kev xa tawm mus rau kev lag luam xws li Tebchaws Meskas, Nyiv, thiab Australia. Cov xwm txheej loj xws li Aichi Expo hauv Nyij Pooj thiab 2000 Olympic Games hauv Australia tau ua lub luag haujlwm catalytic hauv kev txhawb nqa kev tsim cov ntawv-yas kev lag luam.

Hloov mus rau C6 cov khoom:

Vim yog kev lag luam rog, tshwj xeeb tshaj yog kev txhawj xeeb thiab kev sib hais plaub txog PFOA, cov tuam txhab tau hloov pauv los ntawm cov khoom lag luam C8 thawj zaug rau cov khoom siv roj carbon-rau. DuPont kuj tau qhia txog lub cim tshiab ntawm C6 cov khoom lag luam, xws li Capstone™ P-620 thiab P-623, uas tau txo qis kev ua tau zoo piv rau cov khoom siv carbon-yim. Kev lag luam teb tsis tau zoo tagnrho, feem ntau vim hais tias, vim muaj kev cuam tshuam ntawm perfluorooctanoic acid (PFOA), DuPont tau maj mam tawm ntawm daim ntawv Grease-repellent kev lag luam.

 

Cov tuam txhab tshuaj tshwj xeeb cov ntawv tshwj xeeb kuj tsis nyob twj ywm. Lawv tau ua tiav cov khoom lag luam Advanced roj-repellent. Ciba-Geigy, raws li ib tug loj heev nyob rau hauv daim ntawv tshwj xeeb tshuaj kev lag luam, tau qhia cov khoom xws li Lodyne P-201, P-208E, P-504, 514, Lodyne-2000, 2010, thiab 2020, thiab kuj tau txais ib qho chaw nyob rau hauv lub pulp molding lag luam. Lodyne-2020 yog ib yam khoom zoo heev, nrog rau qhov ua tau zoo tshaj plaws ntawm fluorine ntawm txhua yam khoom, txhais tau tias nws ua tiav cov roj ntau tshaj plaws nrog tsawg kawg ntawm cov khoom siv fluorine.

Kev tshwm sim ntawm Japanese tuam txhab:

Lub tuam txhab Japanese fluorine chemical tuam txhab Asahi Glass Co., Ltd. (AGC) kuj tau qhia cov tshuaj tua kab mob, suav nrog cov qauv xws li AG-530, AG-550, thiab cov qauv tom qab xws li AGE-060 thiab AGE-860.


Lwm lub tuam txhab Japanese tshuaj fluorine, Daikin Industries, Ltd., kuj tau qhia cov qauv roj-resistant, xws li TG-410, TG-810, thiab tom qab qauv zoo li TG-8811 thiab TG-8111. Cov khoom lag luam los ntawm ob lub tuam txhab Japanese no, tshwj xeeb tshaj yogC6 cov khoom lag luam, tau ua tiav sai sai ntawm kev lag luam sib txawv ntawm cov tuam txhab European thiab Asmeskas xws li DuPont maj mam tawm hauv kev ua lag luam.

 

Kab lus no muab cov ntsiab lus ntawm cov khoom lag luam ntawm cov tuam txhab no, nrog rau kev rov qab los ntawm ib lub sijhawm.Thaum twg ntsib cov khoom lag luam los ntawm cov tuam txhab muaj npe nrov hauv ntiaj teb no, kuv kuj tau tshawb xyuas qee qhov kev xav paub. Txij li cov khoom lag luam no tau thov rau FDA pom zoo, lawv cov qauv tshuaj tuaj yeem nkag siab los ntawm cov ntaub ntawv muaj nyob hauv pej xeem. Tau ntsib nrog cov qauv tsim tshuaj lom neeg uas tsim los ntawm cov tuam txhab no, ib tus tsis tuaj yeem pab tab sis ua siab zoo qhuas thiab hwm cov tswv yim tshuaj ingenious ntawm cov kws tshawb fawb. Tej zaum qhov no yog qhov piv txwv ncaj tshaj ntawm kev siv tshuab hloov pauv lub neej li cas.

 

Yav tom ntej Prospects thiab Innovation:

Raws li peb fim lub qhov rais ntawm lub sij hawm rau theem-tawm ntawm fluorine-muaj roj repellent, yuav ua li cas cov khoom tshiab nyob thiab sau cov kev xav tau ntawm lub lag luam no kuj yog ib tug mus tas li los ntawm ntau yam tuam txhab uas muag tshuaj. Ningbo Chem-ntxiv Cov Khoom Tshiab Cov khoom siv roj tsis muaj fluorine tau txais kev paub txog kev lag luam txij li thaum nws pib. Nws tsis muaj fluorine, ua tau raws li cov qauv kev ua tau zoo, thiab siv tau yooj yim. Peb vam tias yuav ua haujlwm nrog cov npoj yaig hauv kev lag luam los txhawb kev lag luam kev lag luam.

Hauv kev xaus, kuv xav qiv ib nqe lus los ntawm tus tsim lub tsheb, Carl Benz:

"Tus txheej txheem ntawm invention nws tus kheej yog ib txhiab lub sij hawm zoo tshaj qhov invention tshwm sim."
