I-PFOA, i-PFOS ibangele ungcoliseko lwehlabathi, ingxaki yongcoliseko lwefluorine ithande ukuba nzulu, iPFOA yeyona nto inzima kakhulu ukuthoba isidima sezinto eziphilayo, eziye zafunyanwa kwiArctic;ngo-Oktobha 27,2017, (PFOA) njengeklasi ye-2B carcinogensyadweliswa kwiI-WHO International Institute of Cancer uluhlu lwe-Cancer carcinogens.Okwangoku, iintlobo ze-33iikhompawundi fluoride baye bathintelwa, kwayeI-PFOA SIMAHLA, iPFOS amalaphu angangeni manzi SIMAHLAziya zithandwa ngakumbi.

(1）Indlela yokusebenza yefluorine engenamanzi

Undoqo wokungangeni manzi kukunyusa i-engile yoqhagamshelwano phakathi kwamathontsi kunye nomphezulu welaphu, obonwa ngokubanzi ngokugqitywa kokungena manzi;Ukugqitywa kwelaphu lokungangeni manzi yinkqubo yokuhambisa i-polymer esebenzayo kunye nesiphumo sokungangeni manzi kwilaphu ngokusebenzisa isigaba samanzi, kunye nokwenza ulungelelwaniso oluqhelekileyo nolucwangcisiweyo.kumphezulu welaphu, udlala umphumo wokungangeni kwamanzi.

Ukungangeni kwamanzi okuFluorous kuxhomekeke kwipropathi eyomeleleyo yecrystallization ye-fluoride monomer, egqibezela ngokulula ilungiselelo eliqhelekileyo lomkhombandlela kumphezulu welaphu.Kodwa malunga nokusebenza kwekristallisation ye-ejenti ebuthathaka engenamanzi ye-fluorine, efuna ukufikelela kwisiphumo esifanayo sokungangeni kwamanzi kuya kuba nzima ngakumbi, ngoko ke i-arhente engenamanzi engena-fluorine ngokubanzi iya kuyila "icandelo elimiselweyo" elikhethekileyo.to nceda ukuhlanganisana kwamanzi kwilaphu.Umahluko ekusebenzeni kwe-agent nganye engenawo amanzi e-fluorine ubukhulu becala ngokomahluko wamacandelo amiselweyo.

(2) Ubunzima bokusetyenzwa kwamanzi obungangeni manzi kunye nezisombululo

a.Indlela yokunciphisa ukuveliswa kwamanqaku amhlophe?

Kwinkqubo yokungangeni manzi kwefluorine, ngenxa yezinto zeparafini kwiarhente yokungangeni manzi, iiarhente ezingangeni manzi ziqokelelana kumphezulu wefiber.kwaye abaninziezinye izizathu, ezikhokelela ukuba amanqaku amhlophe avele elaphuni ngokulula.I-agent engenamanzi e-fluorine TF-5016A inokunciphisa ukuveliswa kwamanqaku amhlophe ngokunciphisa inxalenye yeparafini kunyenciphisa ubungakanani besuntswana le-arhente engangeni manzi.Ngokujonga iimfuno eziphezulu zengxaki yokuphucula amanqaku amhlophe, uhlobo oluqukethe i-silicon ngaphandle kwe-fluorine i-agent engangeni manzi i-TF-5910 lolona khetho lungcono.

b.Indlela yokuphucula umphumo wokungangeni kwamanzi?

I-Fluoro-free Icrystallization ye-agent engenamanzi imbi, ukuxinana komphezulu kukhulu kakhulu, kunokubonakala umphezulu welaphu ungekho mtsha, amaso amanzi ancangathi kunye nezinye izinto.I-ejenti engenamanzi e-Fluor-free TF-5016 imveliso eyomeleleyo engangeni manzi ingasetyenziselwa ukuphucula ilaphu ngokunciphisa ukuxinezeleka komphezulu we-fluorine-free arhente engenamanzi, ukuphucula icrystallization, ukuphucula isiphumo sokungangeni manzi kwelaphu.

Kwinkqubo ye-fluorine-free-processing waterproof processing, kuya kubakho kwakhona iintlungu ezinjengokomelela okubi kokuhlutha, ukunganyangeki koxinzelelo lwamanzi, ukuqhekeka okungalunganga, ukuguqulwa kombala omkhulu, iimpawu zokumisa kakubi emva kokuhlamba, njalo njalo.Enokuthi iphuculwe kwakhona njengezisombululo ezingezantsi.
