Formalin. Kuyini lokhu Izinto?

Abaningi abake bakuzwa kule ndaba, njengoba formalin. Kuyini lokhu kwakwakhe chemical? Ivame ukubizwa formol. Kuyinto isixazululo we-formaldehyde (36,5-40%). Njengoba isimame, iqukethe methyl utshwala (4-12%). Lo luketshezi kungekho nto enemibala emihle esobala has a iphunga okunoshukela. Kungaba exutshwa utshwala amanzi kunoma yimuphi isilinganiso.

Formalin: kuyini?

Le into isetshenziswa njengoba ngokuvamile sanitizer. izixazululo zayo (0.5-1%) isetshenziselwa ukugeza isikhumba nge ukujuluka eqinile (imilenze, emakhwapheni) kanye bromidrosis (abukhali nephunga izithukuthuku). Formalin liphumelele ukunciphisa uketshezi of epidermal nezindlala, kodwa ayikwazi ukusetshenziswa nsuku zonke. Kwezinye izimo, kuba esetshenziswa ukunisela (at lokuhlushwa 0.05%), ukuwasha idlala Crypt (0.25%). Le into siyingxenye ye "Lysoform" amalungiselelo "Formidron" "formalin Wamafutha", "Namathisela Teymurova".

Imiphumela emibi ngenkathi usebenzisa lokhu isixazululo: ukucasulwa ubala futhi overdrying esikhumbeni, okuyinto ubalekela lapho lubricating ngayo ukhilimu amafutha noma uwoyela zemifino. Formalin, yiziphi izinhlelo zokusebenza is contraindicated ku ukuvuvukala noma ukuluma kwesikhumba we epidermis ingasetshenziswa kuphela emva ukususwa kwabo.

Ukuze magciwane zomculo yezokwelapha nezinto iziguli futhi usebenzise lesi isixazululo. Isicelo kulokhu banephupho% 0.5 kuphela formalin. Kuyini lokhu izidakamizwa? Ngokusebenzisa e ngezinhloso zokwelapha kuphela ukukhiqiza isixazululo 10% ngo ingilazi izitsha eziyisikhombisa 100 ml. Formalin agcinwe endaweni esitsheni kahle evaliwe endaweni emnyama ezingeni lokushisa 9˚S hhayi kancane. Le into ibhekwa ezinobuthi ezingaba yingozi kubantu nezilwane.

I chemical ukubunjwa formalin

kuyinto formalin kanjani? Ifomula kwale nto - CH ₂ O. I-formaldehyde (formic aldehyde acid) okuyinto igesi kungenambala nge iphunga angafi, ngenkathi lwaluyophola kuya -21 ° C uguqulwe ketshezi. ukuncibilika yayo Iphuzu liwukuthi -92 ° C. namachibi ngakho iguqulwe ibe formic acid. Formaldehyde is etholwe isenzo emoyeni i-oksijini ukuze methanol efomini umusi in khona catalysts. Kulawa, esiliva yayithela kakhulu, nakuba umkhakha isebenzisa zethusi ibekhona. Amanzi atholakala distilled aqoqana, kuphumele formalin. Kungase aqukethe ukungcola ka acetone, acetic noma formic acid. Ukuhwamuka we ezitholakala e formalin mass aminyene polymers okuyizinto zingaxazululeki ngamanzi abandayo.

izakhiwo formalin

Le into ebangela izinguquko ezingenakuhlehliswa e namaprotheni of protoplasm. Kulokhu, kubalulekile necrotizing nezicubu mummified. Ngaphansi kwethonya lokhu ikhambi amaseli webhaktheriya is denatured amaprotheni yabo. Ngezinye 5% formol ngoba 0.5h die spore isikhunta. Ngaphansi kwethonya-hemoglobin formalin iba methemoglobin (ubuthi namachibi umkhiqizo). Phakathi isitoreji isikhathi eside egunjini abandayo, ikhambi iba esinamafu. Lokhu yakha kwenze olumhlophe - paraformaldehyde.

Ukusebenzisa isixazululo formaldehyde

Formalin isetshenziswa njengoba umthombo elula we-formaldehyde, elisetshenziswa ukukhiqizwa polyvinyl esisemthethweni. Libuye esisemqoka njengenhlangano isinqandakuvunda ngokuba magciwane kwezakhiwo, amathuluzi, izingubo, ukushuka izikhumba. Isetshenziselwa nokugqumisa organic izinto (eziphilayo kanye nezinhlaka). Formalin, okuyinto isicelo ukuze kulondolozwe amalungiselelo ezicacile zomzimba akumangalisi futhi lisetshenziswa njengedivaysi fungicide. abatshali Abaningi kwagxila yilo isixazululo, imbewu, nezilimo eziyizigaxa, izimpande ngaphambi kokutshala futhi betshala.

Formalin, okuyinto ilawulwa izinga GOST 1625-89, elisetshenziswa womshini inhlaka zokwenziwa, surfactants, iraba, alcohols polyhydric , namanye amagama ahlobene of methylene. isixazululo formaldehyde nawo ayewusebenzisa basembonini yendwangu. Isetshenziselwa yokuthuthukisa izindawo yabathengi ukumelana izicubu ukuba ukuncipha futhi imibimbi. Esikhathini umkhakha iphepha formalin kuthuthukisa izinga iphepha futhi amandla awo.

siphephe uma usebenza nge formalin

By ukuthenga kule ndaba akufanele sikhohlwe ukuthi kungenzeka kube formaldehyde yingozi. Hlobo luni babeqaphile? Isiqinisekiso inkathi isitoreji izidakamizwa kusukela ngosuku yokukhiqiza - izinsuku ezingu-90. Formalin okuthengiswa amabhodlela, amathini, izigubhu. isixazululo formaldehyde kufanele igcinwe kude nezingane. Lapho ethola formalin ngaphakathi kukhona umuzwa esivuthayo ubuhlungu emphinjeni nasesiswini. Ngemva kwalokho kukhona ngiphalaza igazi. Futhi, lapho formalin ubuthi kwenzeka ukukhwehlela, sneezing, komzimba samehlo, iphika. Umuntu bangezwa amajaqamba, isiyezi, uvalo. Kwezinye izimo, formalin ubuthi ziyabulala, okuyinto eyenzeka ngenxa ukukhubazeka zokuphefumula kanye ukuphelelwa wumoya. umthamo Lethal - 10-15 ml ye 35% isixazululo. Iphunga-formaldehyde e lokuhlala eliphezulu ingabagulisa ukusabela nomzimba.
