Mafunso Ofunsidwa Kawirikawiri Pa Nsalu Yopanda Fluoro Yosalowa Madzi

PFOA, PFOS zayambitsa kuipitsa dziko lonse lapansi, vuto la kuipitsa kwa fluorine nthawi zambiri limakhala lalikulu, PFOA ndiye chinthu chovuta kwambiri kuwononga zachilengedwe, chomwe chapezekanso ku Arctic; pa Okutobala 27, 2017, (PFOA) monga gulu la 2B carcinogensadalembedwa muMndandanda wa WHO International Institute of Cancer carcinogens. Pakadali pano, mitundu 33mankhwala a fluoride akhala oletsedwa, ndipoNsalu zosalowa madzi za PFOA ZAULERE, PFOS ZAULEREkukhala wotchuka kwambiri.

(a)1） Njira yogwirira ntchito yopanda madzi ya fluorine

Chofunika kwambiri cha kusalowa madzi ndikuwonjezera ngodya yolumikizirana pakati pa madontho ndi pamwamba pa nsalu, zomwe nthawi zambiri zimachitika kudzera mu kumaliza kosalowa madzi; Kumaliza kosalowa madzi ndi njira yotumizira polima yogwira ntchito ndi mphamvu yosalowa madzi ku nsalu kudzera mu gawo la madzi, ndikupanga dongosolo lolunjika bwino komanso lolunjika.pamwamba pa nsalu, zomwe zimapangitsa kuti isalowe madzi.

Madzi osalowa madzi osalala amadalira mphamvu ya crystallization ya monomer ya fluoride, yomwe imamaliza mosavuta dongosolo lolunjika bwino pamwamba pa nsalu. Koma za momwe crystallization imagwirira ntchito ya crystallization ya fluoride-free waterproof agent yofooka, yomwe ikufuna kukwaniritsa zotsatira zomwezo zosalowa madzi, zidzakhala zovuta kwambiri, kotero fluorine-free waterproof agent yonse ipanga "gawo lokhazikika" lapadera.to thandizani kusonkhana kosalowa madzi pa nsaluKusiyana kwa magwiridwe antchito a chinthu chilichonse chosalowa madzi chopanda fluorine kumatengera kwambiri kusiyana kwa zigawo zokhazikika.

(2) Mavuto ndi njira zothetsera mavuto osalowa madzi opanda ufa

a. Kodi tingachepetse bwanji kupanga zizindikiro zoyera?

Mu ndondomeko ya fluorine-free madzi, chifukwa cha zigawo za parafini mu wothandizila madzi, zinthu zosalowa madzi zimasonkhana pamwamba pa ulusindi ambirizifukwa zina, zomwe zimapangitsa kuti mabala oyera awonekere mosavuta pa nsaluyo. Chosakaniza chosalowa madzi cha TF-5016A chopanda fluorine chingachepetse kupanga mabala oyera mwa kuchepetsa gawo la parafini ndichepetsani kukula kwa tinthu tomwe sitilowa madzi. Poganizira zofunikira kwambiri pa vuto la kukonza chizindikiro choyera, mtundu wokhala ndi silicon wopanda fluorine wosalowa madzi TF-5910 ndiye chisankho chabwino kwambiri.

b. Kodi mungatani kuti muwongolere mphamvu yothira madzi?

Yopanda fluoro Kusungunuka kwa makristalo osalowa madzi ndi koipa, kugwedezeka kwa pamwamba ndi kwakukulu kwambiri, kungawoneke ngati pamwamba pa nsalu si patsopano, mikanda yomata yamadzi ndi zochitika zina. Zinthu zolimba zosalowa madzi zopanda fluor TF-5016 zitha kugwiritsidwa ntchito kukonza nsalu pochepetsa kugwedezeka kwa pamwamba pa chinthu chosalowa madzi chosalowa fluorine, kukonza kusungunuka kwa makristalo, ndikuwongolera mphamvu yosalowa madzi ya nsalu.

Pakukonza zinthu zopanda fluorine zomwe sizilowa madzi, padzakhalanso malo opweteka monga kufooka kwa kuchotsedwa kwa madzi, kukana kupanikizika bwino kwa madzi, ming'alu yolakwika, kusintha mtundu kwakukulu, kuuma koyipa mukatsuka, ndi zina zotero.Zomwe zingathenso kukonzedwanso monga njira zotsatirazi.
