Iimpawu zeMveliso:
1.Ulwelo olungenambala oluguquguqukayo nolunokutsha, lunuka kamnandi. I-acetone ixubene namanzi, i-ethanol, i-polyol, i-ester, i-ether, i-ketone, i-hydrocarbons, i-halogenated hydrocarbons kunye nezinye izinyibilikisi ze-polar kunye ne-non-polar. Ukongeza kwiioli ezimbalwa ezifana neoli yesundu, phantse onke amanqatha kunye namafutha anganyibilika. Kwaye inokunyibilikisa i-cellulose, i-polymethacrylic acid, i-phenolic, i-polyester kunye nezinye ii-resin ezininzi. Inesakhono sokunyibilika esilambathayo kwi-epoxy resin, kwaye akulula ukuyinyibilikisa i-polyethylene, i-furan resin, i-polyvinylidene chloride kunye nezinye iintlaka. Kunzima ukunyibilikisa umhlonyane, irabha, i-asphalt kunye neparafini. Le mveliso inetyhefu encinci, ukuba ukuxinwa komphunga akwaziwa okanye kudlula umda wokuvezwa, isiphefumlo esifanelekileyo kufuneka sinxitywe. Ukungazinzi ekukhanyeni kwelanga, iiasidi kunye neziseko. Indawo yokubilisa ephantsi kwaye iguquguqukayo.
2.Into enetyhefu enokutsha enetyhefu ephakathi. Ubuthi obunobuthi bunefuthe elicaphukisayo emehlweni kunye ne-mucous membranes yendlela yokuphefumula ephezulu, kwaye ityhefu enzima ineempawu ezifana nokutyhafa, ukuxhuzula, kunye nokubonakala kweprotheni kunye neeseli ezibomvu zegazi kumchamo. Xa kukho ityhefu emzimbeni womntu, shiya indawo ngokukhawuleza, uphefumle umoya omtsha, kwaye uthumele iimeko ezinzima esibhedlele ukuze uhlangulwe.
3.I-acetone yeyodidi oluphantsi lwetyhefu, efana ne-ethanol. Ikakhulu inempembelelo ye-anesthetic kwinkqubo ye-nervous central, i-inhalation yomphunga ingabangela intloko, umbono ophazamisayo, ukuhlanza kunye nezinye iimpawu, umda wokuvumba emoyeni ngu-3.80mg / m3. Ukudibana okuninzi kunye nenwebu yamehlo, impumlo kunye nolwimi kunokubangela ukudumba. Xa ukuxinwa komphunga kuyi-9488mg / m3, emva kwemizuzu engama-60, kuya kubonisa iimpawu zetyhefu ezifana nentloko, ukucaphuka kweetyhubhu ze-bronchial kunye nokungazi. I-Olfactory threshold concentration 1.2 ~ 2.44mg / m3.TJ36-79 ichaza ukuba ubuninzi obuvumelekileyo obuvumelekileyo emoyeni we-workshop yi-360mg / m3.
4.Uzinzo: Izinzile
5.Izinto ezingavumelekanga:Sii-oxidants ezomeleleyo,ii-agent zokunciphisa ezinamandla, iziseko
6.Ingozi yePolymerization:Non-pi-olymerization
