PFOA, PFOS zvakonzera kusvibiswa kwenyika, dambudziko rekusvibiswa kwefluorine rinowanzova rakakomba, PFOA ndiyo inonyanya kuoma kusvibisa zvinhu zvipenyu, iyo yakawanikwa muArctic; musi wa27 Gumiguru 2017, (PFOA) se kirasi 2B inokonzera kenzayakanyorwa murunyorwa rweWHO International Institute of Cancer carcinogens. Parizvino, kune marudzi makumi matatu nematatumakemikari e fluoride zvakaganhurirwa, uyeMachira asingapindi mvura ePFOA, PFOS, maharakuva nemukurumbira unowedzera.
()1） Maitiro ekuita kwemvura isina fluorine
Chinhu chikuru chekudzivirira mvura ndechekuwedzera kona yekubatana pakati pemadonhwe nepamusoro pejira, inowanzoonekwa kuburikidza nekupedzisa kusina mvura; Kupedzisa kusina mvura mujira inzira yekuendesa polymer inoshanda nemhedzisiro isina mvura kujira kuburikidza nemvura, uye kugadzira hurongwa hwakarongeka uye hwakarongeka.pamusoro pejira, zvichiita kuti jira risapinde mvura.
Kusapinda mvura kunobva pakusimba kwe fluoride monomer, iyo inopedzisa nyore nyore kurongeka kwegwara pamusoro pejira. Asi nezvekuita kwe crystallization kwechinhu chisina mvura chisina fluorine chisina simba, icho chinoda kuwana mhedzisiro imwechete yekudzivirira mvura, zvichave zvakaoma, saka chinhu chinowanzo shandiswa chekudzivirira mvura chisina fluorine chichagadzira "chikamu chakagadziriswa" chakakosha.to kubatsira gungano remvura pajiraMusiyano mukushanda kwechinhu chimwe nechimwe chisina fluorine chinodzivirira mvura unoenderana zvikuru nekusiyana kwezvikamu zvakagadzika.
(2) Matambudziko ekugadzirisa mvura asingapindi mvura uye mhinduro dzisina upfu
a. Nzira yekuderedza kugadzirwa kwemavanga machena sei?
Mukuita kwe fluorine-isina mvura, nekuda kweparafini iri mumiriri isingapindi mvura, mishonga isingapindi mvura inoungana pamusoro pefaibhauye vazhinjizvimwe zvikonzero, zvinoita kuti mavanga machena aoneke nyore pajira. TF-5016A isingapindi mvura isina fluorine inogona kuderedza kugadzirwa kwemavara machena nekuderedza chikamu cheparafini uyekuderedza saizi yechinhu chinodzivirira mvura. Tichifunga nezvezvinodiwa zvakanyanya zvedambudziko rekuvandudza mavara machena, mhando ine silicon isina chinhu chinodzivirira mvura chinonzi fluorine TF-5910 ndiyo sarudzo iri nani.
b. Nzira yekuvandudza sei mhedzisiro yemvura?
Hapana fluoro Kugadzika kwechinhu chinodzivirira mvura kwakashata, kusimba kwepamusoro kwakanyanya, zvinogona kuita sekuti pamusoro pejira harisi nyowani, mabhora emvura anonamira nezvimwe zvinhu. Zvigadzirwa zvakasimba zvemvura zvisina fluor TF-5016 zvinogona kushandiswa kuvandudza jira nekuderedza kusimba kwechinhu chinodzivirira mvura chisina fluorine, kuvandudza kusimba kwesimbi, uye kuvandudza mhedzisiro yejira.
Mukugadzirisa kusina fluorine inopindwa nemvura, pachavawo nekurwadziwa kwakadai sekusimba kwekubvisa, kusasimba kwemvura, kutsemuka kusina kunaka, kuchinja kwemavara kukuru, kusaoma zvakanaka mushure mekusukwa, nezvimwewo.Izvo zvinogona zvakare kuvandudzwa semhinduro dziri pazasi.
