Formalin: ntoni na?

Le into isetyenziswa njenge sanitizer rhoqo. izisombululo zayo (0.5-1%) isetyenziselwa ukuhlamba ulusu kunye ukubila eyomeleleyo (imilenze, amakhwapha) kunye bromidrosis (elibukhali nevumba umbilo). Formalin iyasebenza ekunciphiseni secretion unamadlala epidermal, kodwa ayikwazi ukuba isetyenziswe yonke imihla. Kwezinye iimeko, isetyenziselwa ukunkcenkceshela (kwi ndzo ka-0.05%), ukuhlamba idlala crypt (0.25%). Le nto yinxalenye "Lysoform" amalungiselelo "Formidron" "formalin Ioli", "Cola Teymurova".

side effects ngoxa usebenzisa le Isicombululo: ukuluma nokuba overdrying eluswini, leyo liyalahleka xa yokuqaba kunye cream ngamanqatha okanye oli yemifuno. Formalin, isicelo contraindicated kwi yokukrala okanye kwinwebu sangaphandle zingasetyenziswa kuphela emva kokuba ukususwa zabo.

Kuba kweentsholongwane izixhobo zonyango kunye nezinto izigulane ukusebenzisa le sisombululo. Isicelo kulo mzekelo, icinga% 0.5 kuphela formalin. Yintoni na eli chiza? Kusetyenziswa iinjongo zonyango ukuvelisa kuphela isisombululo-10% kuzo iingqayi iglasi ml 100. Formalin agcinwe kwisingxobo evaliweyo kakuhle kwindawo emnyama kubushushu of 9 hayi ngaphantsi. Le into ithathwa ukuba ibe yityhefu ebantwini nasezilwanyaneni.

Le khemikhali Ukubunjwa formalin

Njani na formalin? Ifomula le nto - CH ₂ O. The formaldehyde (formic aldehyde acid) apho yigesi ezingenambala kunye livumba ubhobhoyi, lo gama okupholisa ukuya -21 ° C uguqulwe ulwelo ecacileyo. Indawo yayo yokunyibilika ngu -92 ° C. I igcwala kuwo iguqulelwa formic acid. Formaldehyde efunyanwa sisenzo umoya ioksijini methanol ekwimo umphunga i phambi ehlanganisa. Kwezi, isilivere yaba onemveliso ngakumbi, nangona icandelo isebenzisa ubhedu ekhoyo ngakumbi. Amanzi wafumana Yek oqokelela, nto leyo formalin. Isenokuba ubumdaka acetone, acetic okanye formic acid. Lolwelo eseleyo efunyenwe formalin mass oxineneyo Iipholima leyo ezingenakunyibilika ngamanzi abandayo.

iipropati formalin

Le nto ibangela utshintsho ayibuyiseki umva kwi iiproteni of protoplasm. Kulo mzekelo, oko necrotizing kunye inyama zidumbu. Phantsi nempembelelo yeli isisombululo iiseli iintsholongwane na sisipirithi iiproteni zabo. Kwi-5% formol ngenxa 0.5h fungi die ibihlungu. Phantsi impembelelo haemoglobin formalin uba methemoglobin (Ityhefu imveliso igcwala). Ngexesha yokugcina elide kwigumbi ebandayo, isisombululo kuba lisibekele. Oku kwenza kwenze ezimhlophe - paraformaldehyde.

Ukusebenzisa isisombululo formaldehyde

Formalin isetyenziswa njengomthombo elula formaldehyde, isetyenziswe ukuvelisa Polyvinyl esesikweni. Kwakhona buyafuneka njengokuba magciwane ukuba kwamagciwane kwizakhiwo, izixhobo, impahla, izikhumba bed. Isetyenziswa yabaqholiweyo izinto eziphilayo (izinto kunye namaziko). Formalin, leyo isicelo ukugcinwa ngamalungiselelo zomzimba Ayimangalisi, isetyenziswe fungicide. Abalimi abaninzi azilibale ngulo sicombululo, iimbewu, amatswele, iingcambu phambi kokutyala nokuhlwayela.

Formalin, nto leyo ilawulwa yi umgangatho GOST 1625-89, ezisetyenziswa xa kusenziwa nentlaka zokwenziwa, surfactants, irabha, alkoholi polyhydric , kunye nezinye nezakhi of methylene. isisombululo formaldehyde lwalusetyenziswa kushishino lwamalaphu kweli. Isetyenziswa ukuphucula iimpawu yabathengi yenkcaso inyama ukuze shrinkage kunye nemibimbi. Kushishino bephepha formalin kuphucula umgangatho iphepha kunye namandla awo.

amanyathelo okhuseleko xa usebenza nge formalin

Ngokuthenga lo mbandela asifanele silibale ukuba ukuze ube formaldehyde yingozi. Luni imiqathango? isiqinisekiso of yokugcina impahla into ukususela kumhla lemveliso - iintsuku 90. Formalin kuthengiswa zeebhotile, iinkonkxa, amagubu. isisombululo formaldehyde kufuneka igcinwe kude kude ebantwaneni. Xa ufumana formalin ngaphakathi kukho imvakalelo esivuthayo intlungu kuvuleke iminxunya emathunjini. Emva koko kukho ngohlangothi igazi.

Kwezinye iimeko, formalin Ityhefu ziyabulala, leyo kwenzeka ngenxa ekukhubazekeni bokuphefumla ukuphefumla. ithamo sibulala - 10-15 ml ka-35% isisombululo. Ivumba formaldehyde kungomlinganiselo eliphezulu nako kunokubangela i uxabane.
