Ntsev yog ib yam uas peb muab tso ua ib qho tseem ceeb seasoning rau tais diav. Lub caij no, cov khoom tseem ceeb hauv kev ua noj ua haus yog tus kws kho mob, tus tiv thaiv tej yam yees siv thiab tus pab hauv tsev.
Kev kho mob, ntsev yog siv ntau dua hauv daim ntawv yaj. Cov txheej txheem muaj ib tug xov tooj ntawm nuances uas koj twv yuav raug hu yuav tsum paub txog. Piv txwv li, koj yuav ua li cas 10% saline tov yog tias koj tsis muaj tshuaj ntsuas diav thiab beakers hauv tsev? Yuav tsum tau ntsev thiab dej ntau npaum li cas? Xav txog cov kev xaiv yooj yim rau kev npaj cov tshuaj kho mob.
Yuav ua li cas ntsev yuav tsum tau npaj tshuaj?
Ua ntej koj npaj 10% kua ntsev, koj yuav tsum ua tib zoo kawm daim ntawv qhia. Cov khoom dab tsi hais txog hauv nws? Yog tias lub rooj ntsev, ces cov pob khoom tsim nyog, uas qhia tias:
- khoom ntsev;
- sodium chloride;
- noj ntsev;
- pob zeb ntsev.
Siv hauv lub neej txhua hnublo lus "ntsev", txawm hais tias lo lus no hais txog ntau yam khoom tsim los ntawm cov hlau ions lossis atoms thiab acidic residues. Ntxiv nrog rau sodium chloride, Epsom ntsev - magnesium sulfate yog siv rau kev kho mob. Cov tshuaj yog mined thaum lub sij hawm kev loj hlob ntawm deposits nyob rau hauv lub ntiaj teb crust.
Yog tias koj evaporate dej hiav txwv, koj tau txais ntsev hiav txwv, uas muaj sodium, magnesium, iodine, chloride, sulfate ions thiab lwm yam khoom. Cov khoom ntawm xws li ib tug sib tov yog me ntsis txawv ntawm ib tug neeg tshuaj. Feem ntau, 1-10% saline sodium chloride tov yog npaj los kho qhov txhab, mob caj pas, thiab hniav. Cov tshuaj formula ntawm cov compound uas muaj amazing zog yog NaCl.
Cov khoom xyaw yuav tsum huv npaum li cas?
Yuav ua li cas thiaj ua tau 10% saline hauv tsev kom cov tshuaj muaj txiaj ntsig, tsis ua mob rau lub cev? Ntsev yuav tsum tau ua kom ntshiab li sai tau, tab sis cov ntsev yuav los ntawm lub khw pob zeb feem ntau muaj cov impurities. Muaj cov khoom siv huv huv ntawm kev sib tsoo zoo.
Qee cov zaub mov pom zoo kom siv cov daus lossis dej nag, tab sis qhov no yog lub tswv yim tsis zoo los ntawm qhov pom ntawm niaj hnub ecology. Lub purity ntawm cov kua uas ntws hauv cov dej haus cov tshuab kuj ua rau muaj kev thuam ntau heev. Nws, zoo li daus thiab nag, tuaj yeem kis tau nrog cov tshuaj chlorine, hlau, phenol, roj khoom, nitrates. Cia peb qhia meej tias cov dej distilled lossis demineralized yog siv los ua cov kuab tshuaj hauv tshuaj. Hauv tsev rau kev npaj cov tshuaj, koj tuaj yeem nojlim los yog boiled dej.
Yog tias koj tso cov pwm yas nrog dej rau hauv lub tub yees, cov dej ntshiab yuav khov ua ntej, thiab cov impurities yuav ntim rau hauv qab. Tsis tas tos kom khov tag, nws yog ib qho tsim nyog los sau cov dej khov los ntawm qhov chaw thiab yaj nws. Koj yuav tau dej huv thiab noj qab nyob zoo.
Yuav ntsuas cov ntsev thiab ntim dej li cas los npaj cov tshuaj?
Txhua yam koj xav tau yuav tsum tau sau ua ntej, ua ntej ua 10% kua ntsev. Koj yuav xav tau dej, lub beaker, ib lub hnab ntsev, nplai, ib khob thiab ib diav (lub rooj, khoom qab zib los yog tshuaj yej) rau kev ua haujlwm. Daim duab hauv qab no yuav pab txiav txim seb qhov loj npaum li cas ntawm ntsev muaj nyob rau hauv ib qho khoom qab zib thiab ib teaspoon.
Tom qab ntawd koj yuav tsum txiav txim siab ntawm cov ntsuas ntsuas rau cov kua. Nws ntseeg tau tias qhov loj ntawm 100 ml ntawm dej ntshiab yog 100 g (qhov ntom ntawm cov dej tshiab yog 1 g / ml). Cov kua dej tuaj yeem ntsuas nrog lub beaker, yog tias nws tsis muaj, ces lub khob zoo tib yam ntawm cov hu ua "faceted" yuav ua. Sau rau lub cim, nws muaj 200 ml dej (los yog g). Ncuav tag nrho txoj kev mus rau sab saum toj rau 250ml (250g).
nqe lus "10% daws" txhais li cas?
Kev sib xyaw ntawm cov tshuaj feem ntau yog qhia ntau txoj hauv kev. Feem ntau nyob rau hauv cov tshuaj thiab lub neej txhua hnub, xws li ib tug nqi raws li ib tug luj feem pua yog siv. Nws qhia tau hais tias muaj pes tsawg grams ntawm cov khoom muaj nyob rau hauv 100 g ntawm cov tshuaj. Piv txwv li, yog tias daim ntawv sau tshuaj hais tias siv 10% saline tov, ces txhua 100 g ntawm qhov kev npaj no muaj 10 g ntawm cov kua.
Cia peb hais tias koj yuav tsum npaj 200 g ntawm 10% ntsev tov. Cia peb ua cov lej yooj yim uas tsis siv sijhawm ntau:
100 g ntawm cov tshuaj muaj 10 g ntawm cov khoom; 200 g ntawm cov tshuaj muaj x g ntawm cov khoom.
x=200 g x 10 g: 100 g=20 g (ntsev).
200 g - 20 g=180 g (dej).180g x 1 g/ml=180 ml (dej).
Yuav ua li cas thiaj ua tau 10% saline tov?
Yog lub tsev muaj nplai thiab lub khob, ces nws yog qhov zoo dua los ntsuas cov ntsev thiab qhov ntim ntawm cov dej nrog lawv cov kev pab. Koj tuaj yeem nqa ib lub teaspoon "nrog rau saum" thiab ncuav ib khob dej kom txog rau qhov txaus ntshai, tab sis qhov kev ntsuas no tsis raug.
Yuav ua li cas thiaj ua tau 10% saline tov kom 100 g ntawm cov tshuaj? Koj yuav tsum hnyav 10 g ntawm sodium chloride, ncuav 90 ml dej rau hauv ib khob thiab ncuav ntsev rau hauv dej, nplawm nrog ib diav kom txog thaum yaj. Ntsev yog tov nrog dej sov los yog txias, thiab ces cov tais diav nrog cov khoom yog rhuab. Txhawm rau kom huv si zoo dua, cov tshuaj tiav tau dhau los ntawm lub pob paj rwb (filtered).
Koj tuaj yeem npaj 50 g ntawm 10% daws los ntawm 45 ml dej thiab 5 g ntsev. Hypertonic saline tov yog tsim los ntawm 1 liter dej thiab 100 g ntawm sodium chloride (4 tablespoons tsis saum).
Kho nrog 10% saline tov
Hauv cov tshuaj, cov dej distilled tshiab yog siv los npaj 0.9% ntsev tov, uas yog hu ua "physiological". Cov kua dej no yog isotonic nrog rau kev hwm rau ib puag ncig sab hauv ntawm tib neeg lub cev (muaj tib qhov concentration). Nws yog siv nyob rau hauv ntau yam txheej txheem kho mob, tshwj xeeb tshaj yog, raws li ib tug ntshav hloov, tshem tawm cov teebmeem ntawm lub cev qhuav dej, intoxication.
Hypertonic kua muaj ntsev ntau, nyob rau hauv kev sib cuag nrog isotonic lossis hypotonic kua, nws nyiam dej kom txog thaum cov concentrations sib npaug. Xws li cov nyhuv osmotic yog siv nyob rau hauv pej xeem zaub mov txawv los ntxuav qhov txhab los ntawm cov kua qaub. Ntsev muaj tshuaj tua kab mob, tshuaj tua kab mob, nws cov tshuaj hypertonic yog siv rau lwm cov tshuaj:
- rau cov kab mob ntawm lub cev hauv nruab nrog cev - hauv daim ntawv ntawm daim ntaub qhwv ntsev rau ntawm qhov mob siab;
- ua cov tshuaj pleev ib ce, compresses thiab daim ntawv thov rau daim tawv nqaij thiab lwm yam kab mob;
- zoo li ntsev da dej kom qaug zog thiab mob ntawm tes thiab ko taw;
- rau kev ntxuav cov qhov txhab festering.
Kev kho mob nrog hypertonic 10% saline yuav siv sij hawm, yuav siv sij hawm ntau hnub los yog lis piam. Qhov tsawg kawg nkaus ntawm cov txheej txheem yog 4-7. Rau mob caj pas, siv 3-5% hypertonic saline gargles thaum sawv ntxov thiab yav tsaus ntuj. Lub qhov ntswg kab noj hniav yog ntxuav nrog isotonic saline. Txhawm rau npaj nws, ntxiv 1.2 g ntawm sodium chloride thiab 2.5 g ntawm ci dej qab zib rau 237 ml ntawm boiled dej.
