Sodium dodecyl benzene sulfonate-SDBS cov khoom siv tshuaj zoo, xws li cov tshuaj reagents, tshuaj, txuj lom thiab hluavtaws dyes, xa mus rau cov khoom siv tshuaj uas muaj kev ua haujlwm siab, siab purity thiab tsawg ntau lawm, uas yuav tsum tau siv tshuab siab los tsim. Tab sis qhov ntawd yog ib nqe lus dav dav. Nrog rau txoj kev loj hlob ntawm kev lag luam tshuaj zoo, tib neeg xav tau ntau qhov tshwj xeeb thiab meej. Ua txhua qhov kev xav ua ke, peb tuaj yeem hais tias cov tshuaj zoo yog cov khoom siv tshuaj lom neeg nrog cov yam ntxwv hauv qab no:
(1) Ntau yam, hloov ceev ceev.
(2) Cov zis yog me me, feem ntau hauv batch ntau lawm.
(3 muaj qee yam functionality. Alleged function sex, nws yog lub molecule uas taw tes rau tshuaj ua tej yam kev ua los yog cov nyhuv los ntawm lub cev kev txiav txim, tshuaj lom neeg ua hauj lwm thiab lom. Lub cev ua haujlwm; Antioxidants, roj additives, thiab lwm yam, yog cov tshuaj zoo uas muaj cov tshuaj ua haujlwm lossis lub zog.
(4) Feem ntau ntawm cov khoom yog hybrid cov khoom, thiab cov qauv thiab lwm yam technologies txiav txim siab cov khoom ua tau zoo, thiab muag raws li lub npe ntawm cov khoom.
(5) Kev siv thev naus laus zis siab, xav tau kev tsim kho thev naus laus zis txuas ntxiv ntawm cov khoom tshiab thiab kev tshawb fawb txog kev siv tshuab.
(6) Cov cuab yeej siv me me peev txheej, siab ntxiv cov khoom tsim tawm.
Sodium Dodecyl benzene sulfonate-SDBS txaus ntshai reagent lossis tshuaj lom neeg, uas tuaj yeem hlawv, tawg, corrode lossis cov khoom siv hluav taws xob. Nyob rau hauv kev sib txhuam, kev vibration, kev cuam tshuam, kev sib cuag nrog hluav taws, dej los yog damp, lub teeb muaj zog, kub kub, kev sib cuag nrog lwm yam khoom thiab lwm yam sab nraud, tuaj yeem ua rau muaj zog combustion, tawg, kub hnyiab, raug mob hnyav. Nyob rau hauv cov txheej txheem ntawm kev yuav khoom, khaws cia thiab siv cov tshuaj txaus ntshai, cov kev cai cuam tshuam ntawm lub xeev thiab cov kev cai ntawm cov khoom specification yuav tsum tau ua nruj me ntsis.
Muaj ntau yam tshuaj txaus ntshai uas yuav raug siv hauv tsev kawm ntawv theem nrab chemistry thwmsim. Cov yam ntxwv: volatile, yooj yim rau hlawv thaum qhib hluav taws; Kev sib xyaw ntawm chav thiab huab cua mus txog qhov txwv tsis pub muaj ntau yam, thiab kev tawg ua rau muaj kev kub ntxhov tuaj yeem tshwm sim thaum qhib hluav taws, txim taws thiab hluav taws xob.
1. Cov khoom tawg yooj yim
Cov yam ntxwv: tsis tshua muaj hluav taws xob taw tes, yooj yim rau ignite, nws chav los yog hmoov av tov nrog huab cua rau ib qho twg, nyob rau hauv cov ntaub ntawv ntawm qhib hluav taws los yog Mars, hluav taws xob spark yuav khaus combustion los yog tawg; Flammable los yog tawg nyob rau hauv kev sib cuag nrog oxidizer.
Piv txwv li: naphthalene, camphor, sulfur, liab phosphorus, magnesium hmoov, zinc hmoov, txhuas hmoov, thiab lwm yam.
Kev ceev faj rau kev khaws cia thiab siv: khaws cia rau hauv qhov chaw txias sib nrug ntawm oxidizer, kom deb ntawm hluav taws.
2. Cov kua ua kua
Cov yam ntxwv: volatile, yooj yim rau hlawv thaum qhib hluav taws; Kev sib xyaw ntawm chav thiab huab cua mus txog qhov txwv tsis pub muaj ntau yam, thiab kev tawg ua rau muaj kev kub ntxhov tuaj yeem tshwm sim thaum qhib hluav taws, txim taws thiab hluav taws xob.
Piv txwv li: roj av, benzene, toluene, ethanol, ethyl acetate, acetone, acetaldehyde, chloroethane, carbon disulfide, thiab lwm yam.
Kev ceev faj rau kev khaws cia thiab siv: nws yuav tsum tau muab kaw (xws li kaw lub raj mis kom nruj) kom tsis txhob muab pov tseg thiab dhau mus, khaws cia rau hauv lub txee txias thiab qhov cua, thiab khaws cia kom deb ntawm hluav taws (xws li cov hluav taws xob yooj yim) thiab oxidizer.
3. Lub tshuab hluav taws xob dej
Properties: Reacts hnyav nrog dej, tsim cov pa roj carbon monoxide thiab emits ntau cov cua sov.
Piv txwv li: potassium, sodium, calcium carbide, calcium phosphide, magnesium silicate, sodium hydride, thiab lwm yam.
Kev ceev faj rau kev khaws cia thiab siv: Khaws rau hauv ib lub thawv airtight ruaj rau hauv qhov chaw txias thiab qhuav. Ib qho me me ntawm cov poov tshuaj thiab sodium yuav tsum tau muab tso rau hauv ib lub raj mis uas muaj roj av, kom tag nrho cov poov tshuaj thiab sodium tau muab tso rau hauv kerosene, thiab khaws cia nrog stopper.
