Ngingakwazi yini ukuvuza izicathulo zami?
Ukuhlambalaza ngezinyawo kuyinkinga evamile, nabantu abaningi abanozinyawo zomdlali (tinea pedis) njengesizathu sezimpawu zabo. I-Tinea pedis ingabandakanya yonke indawo yezinyawo, kepha ngokuvamile ihilela indawo ephakathi kwezinzwani - izimpawu zihlanganisa ukucheka, ukuvutha nokugubha, kepha i-tinea pedis nayo ingahle ibe yinto ecacile. Izinsalela ze-allergen zingase zenzeke ezinyaweni, ikakhulukazi ezindaweni ezimilayo.
Abantu abadala abathola i- atopic dermatitis njengengane bangase bathuthukise i-eczema yezandla nezinyawo njengabantu abadala. Uxhumano lwe-dermatitis lungaphinda lubandakanye nezinyawo ngenxa yesikhwama somzimba.
Xhumana ne-Dermatitis ku-Shoes
Uxhumano lwe-dermatitis ngezicathulo ngokuvamile luba njengento enhle, ephuzayo noma ekhanda ngamabhola ezinyawo. Ukuqhuma kungase kube khona nasezintweni zezwane nezinzitho kodwa kaningi akubandakanyi ukuhamba kwezinyawo noma izindawo eziphakathi kwezinzwane. Isifo sofuzo lwesibhedlela kuphela asivami ukuthinta phezulu kwezinyawo. Ucwaningo oluthile lubonisa ukuthi uxhumano lwe-dermatitis ezicathulweni lungathinta zonke izinhlobo zabantu - izingane kanye nabantu abadala, amadoda nabesifazane, nemisebenzi ehlukahlukene, futhi ichazwa ngokukhethekile kwabasebenzi bezempi.
Kunezinhlobo zamakhemikhali ahlukene awaziwayo okubangelwa ukuxhumana ne-dermatitis ngenxa yezicathulo, okuvame kakhulu ukuba yizinhlobonhlobo zamakhemikhali e-raber kanye nama-salts e-chromate, asetshenziswa njengama-tanning agents kumikhiqizo yesikhumba.
Izimbangela ezingavamile ezithinta izifo zofuzo zihlanganisa ama-glues ahlukene, ama-resins, izinsimbi, kanye nezingulube.
Ama-Rubber Compounds
Inhlanganisela ye-rubber evamile kakhulu ebangela isisindo somzimba we-footwear i- mercaptobenzothiazole , kodwa ingabandakanya futhi ama- thiuram , ama- mercapto , ama- mixes we- raberber kanye nama- carba compounds . Lezi zimakhemikhali zikhona nje kuphela izicathulo, ngakho-ke ukugqoka izicathulo ezivela emithini ye-rubber ngokuvamile kubonakala njengamaqabunga amancane phansi kwezinyawo.
Imikhiqizo eqondile eyenza ukuqhuma kungabonakala ngokusetshenziswa kokuhlolwa kwe- patch ; uma kukhonjisiwe, lezo zimakhemikhali ezithile zingagwenywa. Kunezinhlobo ezahlukene zezicathulo, noma ukufakwa kwezicathulo, okungazithengwa ukuze ugweme i-antigen yokuxhumana ebangela isisindo somzimba. Ngokwesibonelo, ukusebenzisa ama-clogs enkuni, izicathulo zepulasitiki noma ukufaka esikhundleni sezinto zenjoloba ngokufakelwa kwesikhala kungase kube indlela yokugwema amakhemikhali abangela inkinga.
I-Chromate
Ama-salts e-Chromate asetshenziselwa inqubo yokuqothula isikhumba. Le makhemikhali yiyona imbangela evamile kakhulu yokuguqulwa kwezicathulo emasosheni ezisebenzi zempi, futhi mhlawumbe nakweminye imisebenzi (njengamaphoyisa kanye nabacimi bomlilo, izisebenzi zokwakha, njll). Ukuhlambalaza okuvela ekuvezeni kwe-chromate kungenzeka phezulu noma phansi kwezinyawo, kuye ngokuthi indawo yesikhumba izicathulo. Ukugwema i-chromate kufanele kube lula ngokumane ugqoke izicathulo ezingewona isikhumba.
Ama-glues nama-resin
I-butylphenol formaldehyde resin iyimbangela evamile yezinwele ezibangelwa ukugaya kanye nama-resin. Le resin isetshenziselwa ukuhlanganisa ndawonye izingxenye ezihlukahlukene zezicathulo, ikakhulukazi isikhumba kanye nezingxenye zenjoloba izicathulo. Ukusabalalisa okuvela e-butylphenol formaldehyde resin ngokuvamile kuvame ukutholakala phezulu nasezinhlangothini ezinyaweni, lapho izingxenye zezingubo eziphezulu zingekho khona.
Ukugwema izicathulo eziqukethe izicucu eziningi ezihlanganiswe ndawonye, futhi kunalokho ukugqoka isihlangu esikhiqizwa esakhiweni esisodwa, kufanele kuvimbele uxhumano lwe-dermatitis kusuka kule resin.
Ama-pig and Metals
Ngokuvamile, abantu bangakwazi ukubhekana nezifo ezihamba ngezinyawo ngenxa yezingulube noma izinsimbi ezitholakala esikhwameni sesicathulo. Lezi zingabandakanya i-chromate, i- cobalt , ihlakaze u-blue 106 noma ezinye izinhlayiya. Ukuhlambalaza okuvela ezihlotsheni ezikhona ngezicathulo kuzovame ukuvela phezulu nasezinhlangothini zezicathulo, lapho isikhumba sithintana nendwangu eboshiwe. Ukugwema izicathulo ezenziwe ngezindwangu ezihlotshisiwe, ikakhulukazi imibala emnyama efana ne-blues, imifino kanye nabamnyama, kufanele ivimbele uxhumano lwe-dermatitis oluvela kuma-pigments.
