PFOA, PFOS tau ua rau muaj kuab paug thoob ntiaj teb, cov teeb meem fluorine muaj kuab paug hnyav heev, PFOA yog qhov nyuaj tshaj plaws rau degrade organic teeb meem, uas txawm tau pom nyob rau hauv Arctic;Lub Kaum Hli 27, 2017, (PFOA) raws li chav kawm 2B carcinogenstau teev nyob rau hauvWHO International Institute of Cancer carcinogens npe.Tam sim no, 33 homfluoride compounds tau txwv, thiabPFOA DAWB, PFOS DAWB cov ntaub tsis muaj dejua ntau thiab nrov.

(1) Mechanism ntawm kev ua ntawm fluorine-dawb waterproof

Lub ntsiab ntawm cov dej tsis zoo yog txhawm rau ua kom lub kaum sab xis ntawm cov tee dej thiab cov ntaub nto, feem ntau pom tau los ntawm kev ua dej tsis sib haum;Npuag waterproof xov yog cov txheej txheem ntawm conveying lub functional polymer nrog waterproof nyhuv rau cov ntaub los ntawm cov dej theem, thiab tsim ib tug tsis tu ncua thiab orderly kev npaj.nyob rau saum npoo ntawm ntaub, ua si cov nyhuv waterproof.

Fluorous waterproof nyob ntawm qhov muaj zog crystallization zog ntawm fluoride monomer, uas yooj yim ua tiav cov kev taw qhia tsis tu ncua ntawm cov ntaub nto.Tab sis hais txog qhov ua tau zoo ntawm crystallization ntawm cov dej tsis muaj fluorine-dawb tsis muaj dej tsis muaj zog, uas xav kom ua tiav cov dej tsis zoo tib yam yuav nyuaj dua, yog li tus neeg saib xyuas tsis muaj dej tsis muaj fluorine yuav tsim tshwj xeeb "tso tivthaiv"to pab cov dej sib dhos ntawm cov ntaub.Qhov sib txawv ntawm kev ua haujlwm ntawm txhua tus neeg saib xyuas dej tsis muaj fluorine yog qhov sib txawv raws li qhov sib txawv ntawm cov khoom ruaj khov.

(2) Cov dej tsis muaj dej tsis muaj dej ua haujlwm nyuaj thiab cov kev daws teeb meem

a.Yuav ua li cas txo cov khoom ntawm cov cim dawb?

Nyob rau hauv tus txheej txheem ntawm fluorine-dawb waterproof, vim hais tias ntawm paraffin Cheebtsam nyob rau hauv tus neeg saib xyuas waterproof, waterproof agents accumulate nyob rau hauv fiber ntau.thiab ntaulwm yam laj thawj, uas ua rau cov cim dawb tshwm ntawm cov ntaub yooj yim.Tus neeg saib xyuas tsis muaj fluorine tsis muaj dej tsis muaj dej TF-5016A tuaj yeem txo qhov tsim ntawm cov cim dawb los ntawm kev txo cov paraffin tivthaiv thiabtxo tus neeg saib xyuas dej tsis zoo particle loj.Raws li qhov xav tau ntau dua ntawm qhov teeb meem kev txhim kho cov cim dawb, cov khoom siv silicon uas tsis muaj fluorine waterproof tus neeg sawv cev TF-5910 yog qhov kev xaiv zoo dua.

b.Yuav ua li cas txhim kho cov nyhuv waterproof?

Tsis muaj fluoro Tus neeg saib xyuas dej tsis zoo crystallization yog qhov tsis zoo, qhov nro ntawm qhov loj heev, tuaj yeem tshwm sim cov ntaub nto tsis tshiab, nplaum dej hlaws thiab lwm yam tshwm sim.Fluor-free waterproof agent TF-5016 muaj zog waterproof khoom siv tau los txhim kho cov ntaub los ntawm kev txo qhov nro ntawm cov dej tsis muaj fluorine, txhim kho cov crystallization, txhim kho cov dej tsis zoo ntawm cov ntaub.

Nyob rau hauv cov txheej txheem ntawm kev ua dej tsis muaj fluorine, kuj tseem yuav muaj cov ntsiab lus mob xws li lub zog tsis zoo, tsis muaj dej tsis zoo, cov kab nrib pleb tsis raug, hloov xim loj, tsis zoo ziab tom qab ntxuav, thiab lwm yam.Uas kuj tuaj yeem txhim kho raws li cov kev daws teeb meem hauv qab no.
