1. Izici:
Ukubukeka ngeso kanye nesimo somzimba: I-White spirit iwuketshezi olucwebile olungenambala olukhanuka njenge-paraffin. Lokhu kuyi-distillate ye-petroleum ehlanjululwe, engenalo iphunga elibi noma elingathandeki. Umkhiqizo uhlinzekwa ngama-brand ahlukene (technical, laboratory, special) anezincazelo ezahlukene zokuhlanzeka.
Ukuncibilika: I-white spirit cishe ayincibiliki emanzini (100 µg/l ku-25°C), kodwa ixubana neningi lezincibilikisi eziphilayo, kuhlanganise nezinye izincibilikisi ze-hydrocarbon, utshwala, ama-ester kanye nezinhlanganisela ezinamakha. Iphrofayela yayo yokuncibilika iyenza ibe isincibilikisi esihle kakhulu samafutha, amafutha amaningi, izinhlaka, ama-wax kanye nezinhlanganisela ezahlukene zama-organic.
Izici zamakhemikhali: I-white spirit iyingxubevange eyinkimbinkimbi yezinto ezicwengiwe kusuka kuwoyela, eyakhiwe ikakhulukazi ngama-alkane agqamile futhi anamagatsha (ama-paraffin), ama-cycloalkane kanye nama-hydrocarbon anamakha. Ngokuvamile iqukethe >65% yama-hydrocarbon C10 noma ngaphezulu. Ibanga lokubila lingu-149–213°C (300–396°F), izinga lokushisa lokuqala ukubamba umlilo — cishe 38°C (100–110°F). Njenge-solvent ye-hydrocarbon, inamandla okuncibilikisa amangqamuzana angawona-polar kanye nama-polar organic compounds. I-white spirit iyasha futhi ingakha izingxube eziqhumayo nomoya (LFL: 0.8%; UFL: 5%). Ayihambisani nama-oxidizer anamandla futhi kufanele igcinwe futhi icutshungulwe ngokuhambisana nemithetho yokuphepha yemikhiqizo kawoyela.
Isimo sokulawula: I-White spirit ihlukaniswa njengento eyingozi. Ngokwe-GHS/CLP, inezigaba zobungozi ezihlanganisa Ingozi yokuphefumula Isigaba 1, Uketshezi oluvutha kalula Isigaba 3 futhi Ubuthi obukhethekile ezithweni eziqondiwe (ukuvezwa okuphindayo) Isigaba 1. Ingase futhi ihlukaniswe njenge-Carcinogenicity Category 1B kanye ne-Germ Cell Mutagenicity Category 1B uma okuqukethwe kwe-benzene kudlula u-0.1%. Le nto iyingozi yokuhogela futhi ingabulala uma igwinya futhi ingena emigudwini yokuphefumula. Ukuvezwa isikhathi eside noma okuphindayo kungabangela ukulimala kwesistimu yezinzwa emaphakathi.
2. Ukusetshenziswa:
Upende, izinto zokumboza nezihlanzi (okuyinhloko): I-white spirit isetshenziswa kabanzi njengesihlukanisi nesincibilikisi embonini yokupenda. Incibilikisa ngempumelelo amafutha, izinhlaka kanye nama-pigment, okwenza kufaneleke kuma-oil paints, ama-varnish kanye nama-enamel. Iphinde isebenze njengesikhundla se-xylene kwezinye izinhlanganisela.
Ukuhlanza izingubo kanye nemboni yezindwangu: Isetshenziswa kabanzi njengendlela yokuhlanza amakhemikhali futhi nokususa amabala.
Ukuhlanza kwezimboni: Isihlanzi esisebenza kahle sokususa amafutha, amafutha kanye nokungcola kwezimboni ezingaphezulu zensimbi.
Izigxivizo, izivalo kanye nama-aerosol: Isetshenziswa njenge-solvent kuma-glue, ama-rubber cement kanye nemikhiqizo ye-aerosol.
Uyinki wokunyathelisa kanye ne-toner: Ingxenye yokudweba nge-inksi kanye ne-solvent kwezinye izinto ezisetshenziswayo zokukopisha.
Izinto zokulondoloza izingodo nemikhiqizo ye-asphalt:Isincibilikisi-sithwali ezinhlakeni zezinto zokuvikela ukubola kwezinkuni kanye nemikhiqizo ye-asphalt.
3. Indlela yokuthola:
Inqubo yezimboni:I-White spirit itholakala ngokuhlunga ngokwezingxenye uwoyela. Ingxenye ebilayo ephakathi nendawo (149–213°C) iqoqwa futhi yenziwe ukuhlanzwa okwengeziwe: ukuhlanzwa nge-hydrogen noma ukwelashwa nge-asidi ukuze kususwe izinhlanganisela zesulfa, ukukhishwa nge-solvent ukunciphisa amazinga ama-hydrocarbon anephunga, i-distillation ukufinyelela ububanzi bokubila obudingekayo, ukoma nokuhlunga.
4. Ulwazi lokuphepha:
Ukuhlukaniswa kwengozi: I-white spirit ihlukaniswa njengento eyingozi enezinkomba zengozi: H304 (Ingabulala uma igwinyiwe futhi ingene emgudwini wokuphefumula), H350 (Ingadala umdlavuza uma i-benzene ingaphezu kuka-0.1%), H340 (Kungabangela ukukhubazeka kofuzo uma i-benzene ingaphezu kuka-0.1%), H372 (Idala ukulimala kwesistimu yezinzwa emaphakathi lapho ichayeka isikhathi eside noma iphindaphindeka). Igama lesignali: Ingozi. NFPA: Ingozi yezempilo 1, Ukushisa 2, Ukusabela 0.
Izingozi zempilo: Ukuhogela umusi kungadala ukucasuka kwemigudu yokuphefumula, ikhanda elibuhlungu kanye nesiyezi. Kungadala ukucasuka kwesikhumba namehlo. Ingozi yokuhogela uma igwinya.
Izinyathelo zosizo lokuqala: Uma ingena emehlweni – geza ngamanzi. Esikhumbeni – geza ngamanzi nensipho. Uma ihogela – umoya omusha. Uma igwinya – UNGAHLANZI, nikeza amanzi noma ubisi, bheka udokotela.
Ingozi yomlilo nokuqhuma: Uketshezi olushisa kalula (izinga lokushisa lokuvutha lingu-38°C). Umusi ungakha ingxube eqhumayo nomoya (LFL: 0.8%; UFL: 5%).
Ukugcinwa nokuzinza:Gcina ezitsheni ezivalwe ngokuqinile endaweni epholile, eyomile, enomoya ohamba kahle. Isikhathi sokusebenza: izinyanga ezingama-24–60 ezitsheni zokuqala ezivaliwe.
Ukuhambisana nomthetho: I-White spirit (CAS#8052-41-3, EC#232-489-3) ifakiwe kurejista ye-EINECS, TSCA, DSL. Ilawulwa yi-OSHA (PEL: 500 ppm) kanye ne-ACGIH (TLV: 100 ppm). Ukuhlukaniswa njenge-carcinogen noma i-mutagen kusebenza uma i-benzene ingaphezu kuka-0.1%. Ukuze uthole ulwazi oluphelele, sicela ubheke kuPasipoti Yokuphepha (SDS).
