В качестве антисептиков (При консервировании коже-веино-по сырь обычно примен ют парадиклорбенвол, нафтал1ин « кремиефторид иатри . Однако все очи мало зффектиВНЫ ПО пр ичине полной нерастворимости первых двух продуктов и незначительной растворимости третьего из них в насыщеином растворе поваренкой соли, -примен емом дл КУНсерви роваии шкур. Кроме того указанные антисептики обладают И р дом других недостатков: так, например, тта радихлорбензол возгон ето уже При ком1натной температуре и требует поэтому герметизащи помещени , .кремнефторид натри токсичен и -при ратоте с иим :необходимо пользоватьс средствами индивидуальной защиты, что ух }дшает услови труда, и др.Parastenorbenvol, naphthal1in cremeefluoride and sodium are usually used as antiseptics for preserving the skin — veino-for raw materials. for KUHN serovirovi skins.In addition, these antiseptics have a number of other disadvantages: for example, TTA radichlorobenzene sublimate is already At room temperature and therefore requires hermetic sealing of the room, neftorid sodium toxic and -with Ratoath with VÚK: polzovats necessary PPE that yi} dshaet conditions, labor and others.
Дл устранени указанных недостатков и, в частности, дл улучшени условий труда .при юоисервированиИ кожевенного сырь предлагаетс примен ть в качестве антисептика нитрит натри . По сравнению с указан1Ньгм1И антисептикам И нитрит натри имеет следующие преимущества: он обладает высокой р1астворимостью в насыщеином растворе поваренной соли - 53 г/л, слабо токсичен но сра внеиию с .ими антисептиками (например, кремнефторииами), н-е Всасываетс через кожу рук и. раздражает слизистые оболочки. Кроме того иитрит натри дешев И при высокой антисептической активности.To eliminate these drawbacks and, in particular, to improve working conditions, it is proposed to use sodium nitrite as an antiseptic when tanning raw materials. Compared with the indicated antiseptics and sodium nitrite, it has the following advantages: it has a high solubility in the saturation solution of sodium chloride — 53 g / l, is slightly toxic, but it is absorbed through the skin of the antiseptics (for example, with cream areas) . irritates mucous membranes. In addition, sodium nitrite is cheap and with high antiseptic activity.
