Yog koj hnov cov lus: caustic soda, caustic, caustic alkali los yog sodium hydroxide, ces paub tias peb tab tom tham txog caustic soda. Cov khoom no yog dab tsi? Nws txawv li cas ntawm baking soda li niaj zaus? Dab tsi yog nws cov khoom, thaj tsam? Qhov twg yog caustic soda feem ntau muag? Cia peb kawm.

Caustic soda yog dab tsi thiab nws txawv ntawm lwm hom dej qab zib li cas

Txhua cov ntsev ntsev ntawm carbonic acid muaj ib lub npe - dej qab zib, uas tuaj yeem yog peb hom:

• zaub mov (sodium bicarbonate);
• calcined (sodium carbonate);
• caustic (sodium hydroxide).

Txhua hom muaj nws tus kheej muaj pes tsawg leeg, cov khoom thiab cov qauv. Yog hais tias peb faib cov sodium tebchaw raws li kev ua phem ntawm qhov cuam tshuam, ces ci dej qab zib yog qhov nyab xeeb tshaj plaws (nws qhov chaw alkaline yog li 8 PH), dej qab zib tshauv "siv nyiaj" (alkaline ib puag ncig - 11 PH), thiab caustic soda yog feem ntau. active alkali (13 PH).

Sodium hydroxide yog ib qho khoom nyob rau hauv daim ntawv ntawm cov muaju, zoo ib yam li cov dej hiav txwv ntsev (dawb los yogyellowish xim). Caustic soda tsis muaj nyob hauv qhov xwm txheej. Nws tsuas yog ib qho khoom ntawm kev lag luam chemical. Cov khoom muaj nyob rau hauv ob qho tib si khoom thiab kua. Nws yog muag nyob rau hauv hmoov los yog gel daim ntawv. Caustic soda yog ib qho kev txhoj puab heev alkali. Yog li ntawd, nws raug thauj mus rau hauv lub hnab tshwj xeeb lossis hauv lub tank.

Qhov tseem ceeb! Nyob rau hauv tus txheej txheem ntawm thauj cov khoom, nws yog tsim nyog los tshem tawm cov cua sov thiab ingress ntawm noo noo rau hauv nws. Cov kev cai tib yam siv tau rau cov khw muag khoom muag caustic soda.

Nws cov khoom

Caustic Properties:

• dissolving hauv dej, nws tso cua sov ntau thiab ua npuas ncauj ntau;
• reacts nrog txhuas, titanium thiab zinc;
• tsis hnov mob nrog cov hlau uas muaj peev xwm electrochemical tsawg;
• tshuaj lom;
• flying;
• highly hygroscopic (uas yog, nws nquag nqus dej vapor los ntawm huab cua).

Qhov tseem ceeb! Lub txee lub neej ntawm caustic soda tsuas yog 1 xyoos xwb: ua raws li txoj cai no.

Caustic daim ntawv thov cheeb tsam

Caustic tau ntev tau ua tiav hauv kev ua liaj ua teb thiab hauv ntau qhov kev lag luam:

• automobile;
• petrochemical;
• metallurgical;
• gas;
• tshuaj;
• food;
• easy.

Caustic soda yog ib qho kev pab zoo hauv kev daws teeb meemntau yam teeb meem hauv tsev, raws li nws zoo kawg nkaus copes nrog ntau yam kuab paug thiab blockages; Nqa rov qab ci rau cov lauj kaub kub. Siv nws, koj tuaj yeem ua xab npum hauv tsev.

Caustic soda muag qhov twg thiab nws tus nqi yog dab tsi? Tus nqi ntawm 1 kg ntawm cov tshuaj no yog hais txog 20 rubles. Koj tuaj yeem yuav nws hauv yuav luag txhua lub khw muag khoom kho vajtse.

Ntawm cov lauj kaub thiab ntxuav hauv pem teb

Txhawm rau lub lauj kaub thiab lauj kaub kom txaus siab rau koj nrog lawv cov ci ntsa iab zoo meej, sib tov dej, dej qab zib thiab xab npum ntxhua khaub ncaws (peb rub nws rau ntawm grater) hauv lub thawv hlau hauv qhov sib piv ntawm 5: 1: 1. Peb kho qhov chaw nrog qhov npaj loj thiab cia lawv nyob ib leeg rau 20-30 feeb, tom qab ntawd yaug txhua yam kom huv si nrog dej ntws.

Qhov tseem ceeb! Teflon thiab txhuas cov khoom yuav tsum tsis txhob raug rau xws li ntxuav.

Txhawm rau tshem tawm tag nrho cov av uas tshwm sim hauv pem teb, ntxiv 3-4 tablespoons caustic soda rau hauv lub thoob dej thiab kho qhov chaw nrog cov tshuaj no. Tom qab ntawd ntxuav hauv pem teb nrog dej huv thiab so qhuav.

Yuav kom ntxuav tsis yog lub nra rau koj thiab mus sai, tsuas yog taug kev mus rau qhov chaw ze tshaj plaws uas cov dej qab zib tau muag thiab yuav khoom kom muaj nuj nqis.

Tshem cov roj stains ntawm khaub ncaws

Txhawm rau tshem tawm cov kab qub ntawm cov khaub ncaws, peb xav kom siv cov lus pom zoo hauv qab no. Ncuav 2-3 teaspoons ntawm caustic soda rau hauv lub tshuab ntxhua khaub ncaws nrog rau cov hmoov (ntxuav kub tuaj yeem yog ib qho). Yog tias koj ntxhua khaub ncaws los ntawm tes, nws kuj ua tausiv caustic soda kom ntxhua khaub ncaws huv si thiab tshiab. Tsuas yog nchuav cov baking soda nrog rau cov hmoov rau hauv dej thiab tso cov khoom nyob rau hauv ib ntus (yog tias muaj kuab paug hnyav: rau 2 teev), ces ntxuav li qub.

Qhov tseem ceeb! Ua ntej: thaum ntxuav tes, nco ntsoov hnav hnab looj tes roj hmab. Thib ob: thaum yuav khoom hauv lub khw muag khoom kho vajtse (qhov chaw muag tshuaj caustic soda), xyuas kom cov khoom zoo (kom tsis txhob muaj teeb meem rau kev noj qab haus huv).

Tshuaj kav dej

Muaj ntau ntau txoj hauv kev los ntxuav cov kav dej koj tus kheej:

Thawj. Ncuav 150-200 g ntawm caustic alkali rau hauv lub ntws thiab ncuav ib khob ntawm boiling dej nyob rau ntawd. Tom qab 10 feeb, ncuav lwm 2.5 liv ntawm boiling dej. Tom qab 1-1, 5 teev, tsis txhob kov cov dej ntws. Tom ntej no, yaug cov kav dej nrog dej kub rau 20-30 feeb

Note! Rau lub hom phiaj tiv thaiv, peb pom zoo kom ua li no tu ib hlis ib zaug.

Second. Peb sib tov lub rooj vinegar nrog dej qab zib thiab ncuav no sib tov rau hauv ib tug clogged yeeb nkab. Kaw lub qhov dej kom nruj nrog cork. Tom qab 2 teev, ncuav dej npau npau, tos dua, thiab tom qab ntawd tig rau dej ntws

Qhov tseem ceeb! Thaum lub sij hawm manipulations, ib qho kev ua phem heev tshwm sim, uas yog nrog los ntawm kev tso tawm ntawm npuas. Ceev faj.

Yog tias koj tsis muaj sijhawm lossis xav siv sijhawm mus rau tom khw lossis tsis paub qhov chaw nyob uas muaj dej qab zib (caustic) muag, koj tuaj yeem xaj online rau nws qhov kev xa tuaj.

Qhia!Ceev faj ntawm cov cuav thiab ua raws li cov lus qhia rau kev siv.

Sodium hydroxide yog siv tsis tsuas yog los cuam tshuam nrog kev txhaws thiab sib sau ntawm cov protein ntau hauv cov kav dej. Feem ntau, cov khoom no tau nkag mus rau hauv cov kav dej thaum kawg ntawm lawv cov kev kho mob acid txhawm rau tiv thaiv lawv ntawm corrosion thiab kev puas tsuaj ntxiv. Los ntawm txoj kev, qhov no yog ib lub tswv yim zoo rau cov lag luam me (raws li kev them nyiaj los npaj kev pab rau cov pej xeem hauv kev nqa cov kav dej phwj tuaj mus rau qhov qub). Kev xa cov dej qab zib tuaj yeem ua los ntawm cov hauv paus uas cov dej qab zib tau muag ntawm cov khw muag khoom thiab cov lag luam wholesale.

txoj cai kev nyab xeeb rau kev ua haujlwm nrog cov dej qab zib caustic

Caustic soda hu ua caustic soda vim yog vim li cas. Tom qab tag nrho, nws corrodes tsis tsuas yog daim tawv nqaij, ntawv, tab sis kuj lwm yam organic teeb meem. Yog li ntawd, thaum siv cov tshuaj no, nws yuav tsum tau ua raws li cov lus pom zoo:

Ua haujlwm tshwj xeeb hauv lub tsho da dej, tsom iav thiab hnab looj tes roj hmab uas ncav cuag lub luj tshib.

• Tom qab npaj cov tshuaj caustic soda, koj yuav tsum tau tos ib pliag thiab tsuas yog pib ua haujlwm.
• Sim kom tsis txhob txaws cov khoom sib tov (caustic yuav ua rau muaj tshuaj lom yog tias nws nkag rau ntawm daim tawv nqaij).
• Thaum kev sib cuag nrog daim tawv nqaij, sai sai ntxuav cov chaw cuam tshuam hauv qab dej ntws, ces so nrog 2% boric acid (yog tias tsis muaj kev txhim kho hauv 30 feeb, koj yuav tsum sab laj nrog kws kho mob).
• Khaws caustic rau hauv lub thawv hlau lossis iav nrog lub hau kaw. Koj tuaj yeem yuav lawv qhov chaw lawv muagcaustic soda.
• Tshwj tsis pub muaj kev nkag mus rau lub caustic.

Yog tias txhua yam kev ceev faj ua raws, ces caustic soda yuav yog ib qho kev pab zoo hauv lub neej txhua hnub.
