Isopropyl cawv, tseem hu ua 2-propanol, yog ib qho ntawm cov kuab tshuaj cawv thiab tshuaj tua kab mob ntau tshaj plaws. Ib qho 70% isopropanol tov yog npaj nrog 70% isopropyl cawv los ntawm ntim thiab 30% cov dej huv huv, thiab qhov sib piv no ua tiav qhov sib npaug ntawm cov tshuaj tua kab mob thiab kev nyab xeeb, uas yog vim li cas nws yog ib qho khoom siv rau tsev kho mob, chaw ua zaub mov thiab kev tu tsev. Vim hais tias cov tshuaj tseem flammable txawm tias dilution, kev paub tseeb ntawm nws tus cwj pwm hluav taws thiab kev noj qab haus huv yog qhov ua ntej rau txhua daim ntawv thov.
Muaj pes tsawg leeg thiab cov yam ntxwv tseem ceeb ntawm 70% Isopropanol
70% isopropanol yog sib xyaw ntawm isopropyl cawv thiab dej huv uas cov cawv muaj 70% ntawm qhov ntim thiab qhov seem yog dej. Cov khoom xyaw nquag yog isopropyl cawv nrog CAS naj npawb 67-63-0, molecular mis C3H8O thiab qhov kub ntawm txog 82.5 C. Cov tshuaj yog cov kua tsis muaj xim, pob tshab nrog cov ntxhiab tsw ntxhiab ntawm cawv.
Lub xub ntiag ntawm cov dej txhim kho cov ntub dej thiab ua kom cov evaporation qeeb, uas txuas ntxiv lub sijhawm sib cuag ntawm cov tshuaj tua kab mob thiab qhov chaw. Vim li no, 70% concentration yog qhov zoo dua ntawm kev tua cov kab mob ntau dua li cov dej cawv uas tsis muaj isopropyl, vim tias cov dej tso cai rau cov protein denaturation mus rau hauv cov kab mob microbial ntau dua.
Vim li cas 70% Isopropanol tseem yog cov kua ua kua
70% isopropanol yog cais raws li cov kua hluav taws kub heev nyob rau hauv kev phom sij 2 ntawm cov txheej txheem tshuaj lom neeg. Txawm hais tias nws muaj 30% dej, cov cawv vapor tseem tuaj yeem tsim qhov sib xyaw ua ke nrog huab cua ntawm chav tsev kub, thiab nws tuaj yeem nkag rau hauv kev sib cuag nrog cov nplaim taws qhib, lub qhov hluav taws xob zoo li qub lossis kub kub. Yog li siv thiab khaws cia yuav tsum khaws cov khoom kom deb ntawm qhov hluav taws kub, qhov chaw kub thiab hluav taws xob txhua lub sijhawm.
Thaum siv ntau los yog txau, thaj chaw yuav tsum tau ua kom muaj cua zoo kom tsis txhob muaj vapor. Cov thawv ntim khoom uas tuav 70% isopropanol yuav tsum tau muab kaw kom tsis txhob evaporation thiab khaws cia rau hauv qhov chaw txias. Cov khoom ntau muaj nyob rau hauv kev pom zoo flammable - cov khoom siv ua kua uas muaj hluav taws kub - cov khoom siv tua hluav taws, thiab cov khoom siv hluav taws xob yuav tsum tau tswj kom tsuas yog cov nyiaj uas xav tau rau kev ua haujlwm raug tshem tawm.
Kev siv tseem ceeb ntawm 70% Isopropanol
Qhov tseem ceeb ntawm kev siv 70% isopropanol yog tshuaj tua kab mob thiab tshuaj tua kab mob. Cov tsev kho mob thiab chaw kho mob siv nws los so ntawm daim tawv nqaij ua ntej txhaj tshuaj thiab ntxuav cov khoom siv kho mob; cov tsev neeg thiab chaw ua haujlwm siv nws los tua cov qhov rooj kov, desktops thiab cov khoom siv hluav taws xob. Vim hais tias isopropanol evaporates sai sai thiab tawm tsis muaj residue, nws yog zoo haum rau precision instruments thiab electronics khoom nto.
Tshaj li cov tshuaj tua kab mob saum npoo av, 70% isopropanol yog siv los sib xyaw cawv- cov tshuaj ntxuav tes, tshuaj tua kab mob hauv cov chaw ua haujlwm tshuaj, thiab ntxuav zaub mov- cov cuab yeej ua haujlwm. Nws lub zog tu thiab degreasing kuj ua rau nws muaj cov kuab tshuaj ntau hauv kev lag luam thiab hauv kev lag luam luam tawm kom tshem tawm cov roj thiab cov kua roj vanish.
Kev Nyab Xeeb Kev Nyab Xeeb thiab Kev Tiv Thaiv Tus Kheej
70% isopropanol ua rau khaus qhov muag thiab tuaj yeem ua rau mob thiab liab tom qab kev sib cuag. Kev nqus nws cov vapor hauv chav tsis zoo tuaj yeem ua rau kiv taub hau, tsaug zog thiab txo qis concentration. Kev nqos dej cawv isopropyl tuaj yeem ua rau muaj tshuaj lom uas hnyav heev thiab muaj peev xwm ua neej nyob - hem, yog li cov khoom yuav tsum tau khaws cia deb ntawm zaub mov, dej qab zib thiab menyuam yaus.
Cov neeg ua haujlwm yuav tsum hnav cov hnab looj tes tiv thaiv thiab tsom iav, thiab zam kev sib cuag ntawm daim tawv nqaij ncaj qha thiab nqus pa. Yog tias cov khoom nqos tau yuam kev, nrhiav kev kho mob tam sim ntawd thiab tsis txhob ntuav ntuav, vim tias ntuav tuaj yeem nqus cov kua rau hauv txoj hlab pa thiab ua rau muaj kev raug mob thib ob.
Kev ruaj ntseg cia thiab tuav cov txheej txheem
Khaws 70% isopropanol nyob rau hauv ib qho chaw txias, qhuav, zoo- qhov cua qhov chaw kom deb ntawm qhov qhib nplaim taws, sparks thiab oxidizing agents. Cov thawv ntim khoom yuav tsum tau muab kaw, sau kom meej nrog cov ntaub ntawv txaus ntshai, thiab khaws cia qhov chaw uas menyuam yaus thiab cov neeg ua haujlwm tsis tuaj yeem ncav cuag lawv. Kev khaws cia ntau yuav tsum siv tawg-cov khoom pov thawj thiab rov qab los ntawm hluav taws kub- cov cuab yeej tua hluav taws. Siv ib zaug - koob tshuaj rau txhua txoj haujlwm thiab zam kev txau hnyav hauv qhov chaw kaw. Ua ntej ntxuav cov khoom siv hluav taws xob, txiav lub hwj chim thiab tso cai rau lub cuab yeej kom txias kom cov kuab paug tsis tuaj yeem ua tau raws li cov hluav taws xob.
Hauv cov chaw soj nstuam thiab cov tsev kho mob, lub kaw lus kaw lus rau kev xa tawm 70% isopropanol pab tswj cov khoom muag thiab tiv thaiv kev cia ntau dhau. Cov thawv ntim khoom yuav tsum raug kaw nruj nreem tam sim ntawd tom qab siv, thiab cov kua khib nyiab yuav tsum tau muab khaws cia thiab pov tseg raws li kev nyab xeeb- cov cai pov tseg es tsis txhob muab nchuav rau hauv qhov dej. Qhov cua thiab hluav taws xob- kev tiv thaiv kev teeb tsa hauv thaj chaw cia khoom yuav tsum tau tshuaj xyuas tsis tu ncua, thiab cov neeg ua haujlwm yuav tsum tau txais kev cob qhia kev nyab xeeb ntawm daim ntawv thov raug thiab ntawm cov txheej txheem teb thaum muaj xwm txheej ceev rau kev nchuav thiab raug.
