Cov tsos mob: Cov kua xim tsis muaj xim nrog cov yam ntxwv tsw ntawm cov cawv cawv
Lub cev muaj zog ntawm Isopropyl Cawv
Lub cev lub cev ntawm IPA cawv yog raws li nram no:
- Odor: Sharp cawv tsw
- Ceev: 0.785 g / cm³ (20 degree)
- Kub taw tes: 82.5 degree
- Melting Point: -89 degree
- Flash Point: Kwv yees li . 11.7 degree
- Solubility: Ua tiav miscible hauv dej
- Vapor Siab: 4.4 kPa ntawm 20 degree
- evaporation tus nqi: ceev
- Viscosity: Tsawg
Cov lus piav qhia ntxaws yog raws li nram no:
1. Ceev ceev
Qhov ceev ntawm Isopropyl cawv (IPA) ntawm 20℃yog kwv yees li: ρ=0.785 g/cm³. Qhov no txhais tau hais tias IPA yog sib dua li dej, ua rau nws tsim nyog rau daim ntawv thov uas yuav tsum tau ceev evaporation.
Qhov ceev ntawm IPA cuam tshuam rau kev suav rau cov kuab tshuaj sib tov sib xyaw, kev ua haujlwm ntawm kev ua haujlwm tu, thiab cov kev xav tau rau kev ntim khoom thiab kev thauj mus los. Raws li cov kua tsawg- ntom ntom, nws yooj yim rau twj thiab atomize hauv cov ntawv thov tshuaj tsuag.
2. Boiling Point
Qhov kub ntawm Isopropyl cawv yog: Tb=82.5℃. Qhov ntsuas kub qis no tso cai rau IPA kom evaporate sai, txawm nyob hauv chav tsev kub. Yog li ntawd, IPA yog dav siv nyob rau hauv daim ntawv thov xws li electronics tu, screen printing, kho qhov muag lens tu, tsheb degreasing, thiab nto pretreatment ua ntej tha xim.
Txawm li cas los xij, nws cov yam ntxwv evaporation ceev kuj tseem xav tau tias cov thawv ntim khoom khaws cia kom nruj kom txo tau cov khoom poob.
3. Flash Point thiab Flammability
Isopropyl Cawv yog cais raws li cov kua ua kua heev. Nws lub ntsiab lus yog kwv yees li: Tf ≈ 11.7℃. Thaum qhov kub siab tshaj qhov taw tes no, IPA vapors tuaj yeem ignite tam sim ntawd thaum sib cuag nrog lub txim taws lossis qhib nplaim taws.
Kev ceev faj txog kev nyab xeeb yuav tsum tau ua raws li hauv qab no:
Khaws kom deb ntawm qhov chaw sov thiab qhib nplaim taws.
Siv qhov tawg- pov thawj qhov cua tshuab.
Khaws rau hauv qhov chaw txias, qhuav.
Cov thawv ntim hauv av thaum lub sijhawm hloov chaw.
Hnav cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE).
4. Solubility hauv dej
IPA yog miscible kiag li nrog dej. Nws tuaj yeem sib xyaw nrog dej hauv txhua qhov kev faib ua feem, ua rau cov tuam txhab tsim ntau qib purity, suav nrog:
- 70% Isopropyl cawv
- 91% Isopropyl cawv
- 99% Isopropyl cawv
- 99.9% Electronic-Qib Isopropyl Cawv
(Thaum Yuav Siv 70% Lossis 99% Isopropyl Alcohol IPA Liquid (CAS 67-63-0)?)
Nws zoo heev compatibility nrog dej ua rau nws dav siv nyob rau hauv: tshuaj tua kab mob deg, tshuaj formulations, industrial tu neeg ua hauj lwm, tshuaj pleev ib ce tsim, kuaj daim ntawv thov, thiab lwm yam.
Chemical Properties ntawm IPA cawv
- Chemical Stability: Nyob rau hauv ib txwm cia tej yam kev mob, IPA feem ntau ruaj khov. Txawm li cas los xij, nws yuav ua rau muaj zog oxidizing cov neeg ua haujlwm, acids, thiab chlorinated compounds. Kev cia khoom tsis raug tuaj yeem ua rau cov khoom sib kis lossis ua rau muaj kev phom sij.
- combustion: Thaum IPA tshuaj hlawv nyob rau hauv lub xub ntiag ntawm oxygen, nws tsim carbon dioxide thiab dej.
- Volatilization Yam ntxwv: Vim nws lub siab vapor siab thiab qis qis, 2-propanol evaporates sai dua dej. Cov yam ntxwv no ua rau IPA cawv zoo tagnrho rau kev ntxuav daim ntaub ntawv, muab kev ziab sai, cov seem seem tsawg, lub voj voog luv luv, thiab kev ua haujlwm siab.
- Hygroscopic Properties: Thaum lub sij hawm, nws absorbs noo noo los ntawm huab cua. Qhov teeb meem no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov hauv qab no:
- Electronic-qib isopropyl cawv
- Pharmaceutical -qib isopropyl cawv
- High -cov ntawv thov kev kuaj dawb huv
