Iipropati zeMveliso kunye noZinzo:
I-1.I-toxicity encinci kakhulu kunye nokubuyisela ngokukhawuleza kwi-poisoning, ngoko inokusetyenziswa njenge-anesthetic.Ukucaphukisa ulusu kunye ne-mucous membrane.Iimpuku zabantu abadala abancinci ngomlomo LD50: 1.6mL/kg.Uxinzelelo lomoya oluphezulu oluvumelekileyo lwe-500 × 10-6.Ukusebenza kufuneka kunxibe imaski yegesi, ifunyenwe ityhefu ngokukhawuleza isuswe kwindawo, unyango lweempawu.Ubuncinci kwikloridi yemethane.Umphunga uphezulu kakhulu kwaye ukuphefumla imiyinge emikhulu kuya kubangela ityhefu ebukhali kunye neentlungu zempumlo, intloko ebuhlungu kunye nokugabha.Ubuthi obungapheliyo bubangela isiyezi, ukukhathala, ukulahlekelwa ngumdla, impaired haematopoiesis kunye nokuncipha kweeseli ezibomvu zegazi.Ulwelo lwe-methylene chloride lubangela i-dermatitis xa udibana nolusu.Ukuphefumla umphunga oyi-90.5g/m3 kwiimpuku ezibulewe kwimizuzu engama-90.I-olfactory threshold concentration yi-522mg / m3 kwaye i-concentration ephezulu evumelekileyo kwindawo yokusebenza yi-1740mg / m3.
2.Uzinzo: Izinzile
3.Izinto ezingavumelekanga: Isinyithi se-alkali, i-aluminium
4.Imiqathango yokuphepha ukuvezwa: Ukukhanya, umoya ofumileyo
5.Ingozi yokwenziwa kwePolymerisation: Ukungasetyenziswa kwepolymerisation
Isicelo seMveliso:
1.Ukongezelela kwi-organic synthesis, le mveliso isetyenziswa ngokubanzi njengefilimu ye-cellulose acetate, i-cellulose triacetate pumping, i-petroleum dewaxing, i-solvents ekuveliseni i-aerosols kunye ne-antibiotics, iivithamini, i-steroidal compounds, kunye nokucoca i-lacquer yomhlaba kunye nokunciphisa kunye ifilimu ukususa.
2.Isetyenziswe kwi-grain fumigation kunye nefriji yeefriji eziphantsi koxinzelelo kunye neeyunithi zomoya.Isetyenziswa njenge-arhente encedisayo yokuvuthela kwimveliso ye-polyether urethane foam nanjenge-ejenti yokuvuthela ye-polysulfone foam ekhutshiweyo.
3.Isetyenziswe njenge-solvent, i-extractant kunye ne-mutagen.Isetyenziswa kuphando lwemfuza yezityalo.
I-4.Ine-solvency enhle, i-solvency ephantsi yokubilisa kunye ne-toxicity encinci kunye nokungatshanga phakathi kwe-solvents ye-industrial esetyenziswa ngokuqhelekileyo, kwaye ine-solvency enhle kwii-resin ezininzi, i-parafini kunye namafutha.Isetyenziswa kakhulu njengepeyinti yepeyinti, i-petroleum dewaxing solvent, i-extractant ye-thermal-unstable substances, i-extractant ye-lanolin esuka kwiboya kunye neoli edliwayo evela kwi-coconut, i-solvent ye-cellulose triacetate film.Ikwasetyenziswa ngokubanzi kwifibre yeacetate, ukwenziwa kwefiber yevinyl chloride, ukusetyenzwa kunye nokucima umlilo, izikhenkcezisi, iurotropine kunye nezinye izinto ezenziwayo.
5.Isetyenziswa kwishishini lombane.Ngokuqhelekileyo isetyenziswe njenge-arhente yokucoca ukususa ioli.
I-6.Isetyenziswe ngokubanzi njenge-solvent ye-flame retardant eneqondo eliphantsi kakhulu lokubilisa.Ukongeza ekuhlambeni izinyibilikisi zeenjini zenqwelomoya, oomatshini bokuchaneka, njl.njl., isenokusetyenziswa njengesixhobo sokuhluba iipeyinti, kwaye ingaxutywa nezinye izinyibilikisi eziza kusetyenziswa kwiindidi ezahlukeneyo zokuhlamba kwimizi-mveliso.
I-7.Ikwasetyenziswa njenge-ethyl ester fiber solvent, i-anesthetic yendawo yamazinyo, i-refrigerant kunye ne-agent yokucima umlilo, njl.
I-8.Isetyenziswa njenge-solvent kwi-resin kunye nemveliso yeplastiki.
Amanqaku okuGcina iMveliso:
1.Gcina kwindawo epholileyo nengena umoya.
2. Gcina kude nomlilo kunye nomthombo wobushushu.
3.Gcina kwiqondo lobushushu elingadluliyo kuma-32°C kunye nokufuma okuhambelanayo okungadluliyo kuma-80%.
4. Gcina isitya sivaliwe.
5. Kufuneka igcinwe ngokwahlukileyo kwisinyithi se-alkali kunye neekhemikhali ezidliwayo, kwaye akufanele neze ixutywe.
I-6.Ixhotyiswe ngeentlobo ezifanelekileyo kunye nobuninzi bezixhobo zokucima umlilo.
7.Indawo yokugcina kufuneka ixhotywe ngokuvuza kwezixhobo zonyango olungxamisekileyo kunye nezixhobo ezifanelekileyo zokukhusela.
