Xeb yog ib qho "mob" ntawm cov hlau. Cov khoom siv ruaj khov, ntau yam muaj nyob ib puag ncig peb. Lawv siv los tsim cov khoom siv hauv tsev, tsheb, tsheb thauj mus los thiab lwm yam. Tag nrho cov fasteners ruaj tshaj plaws kuj yog ua los ntawm hlau. Tab sis ntawm no yog qhov teeb meem: dhau sij hawm, ntau ntawm lawv succumb rau oxidation - corrosion. Cov khoom raug puas tsuaj los ntawm ib puag ncig, thiab cov qauv pib deteriorate. Yuav ua li cas kom txuag tau hlau los ntawm kev tuag tsis tau? Koj yuav xaiv qhov twg xeb tshem tawm? Cia peb xav txog hauv kab lus.

Tshem tawm cov av teeb

Pom kab xeb sai dua, nws yooj yim dua los daws nws. Yog hais tias qhov kev puas tsuaj yog tsis heev embedded nyob rau hauv cov hlau, nws yog txaus mus rau ib tug neeg kho tshuab tu txoj kev. Txhawm rau ua qhov no, koj tuaj yeem kho qhov chaw nrog txhuam txhuam. Kev sib tsoo yuav tshem tawm cov txheej av thiab txuag cov hlau los ntawm kev sib kis ntxiv ntawm "kev kis kab mob".

Nws yog ib qho tsim nyog sau cia tias cov txheej txheem tu tshuab kuj tseem siv los tiv thaiv cov xeb sib sib zog nqus ua ntej siv cov tshuaj kom ua tiav cov txiaj ntsig zoo tshaj plaws. Raws li ib tug tawv txhuamCov ntawv xuab zeb tuaj yeem siv tau.

Auto Cleaner

Cov tshuaj txhuam hniav zoo yog lub tshuab ntxuav tsheb hlau. Cov cuab yeej no muaj: nws tuaj yeem yuav ntawm txhua lub khw tshwj xeeb hauv cov khoom siv tsheb. Ua ntej daim ntawv thov, nws raug nquahu kom ntxuav qhov chaw cuam tshuam los ntawm xeb nrog txhuam tawv. Tom qab ntawd, thaj chaw yog them nrog ib txheej ntawm tus neeg sawv cev txog li 5 millimeters tuab thiab sab laug rau ob peb feeb. Tom qab ntawd nws yog ib qho tsim nyog los ntxuav tawm cov seem thiab so saum npoo kom qhuav. Yog tias xeb tsis tag, rov ua cov txheej txheem.

Nco ntsoov tias cov tshuaj txhuam hniav yog tshuaj lom. Cov no feem ntau yog cov kua qaub uas ua rau kub hnyiab yog tias lawv nkag mus rau hauv daim tawv nqaij. Nws yog ib qho tsim nyog los ua haujlwm hauv hnab looj tes tiv thaiv, tsom iav thiab lub tshuab ua pa. Tsis tas li ntawd, nws yuav tsis yog superfluous ua tib zoo nyeem cov lus qhia rau kev siv thiab ceev faj.

Homemade Mortar

Raws li kev sim pej xeem, ntau "tsev" zaub mov rau tshem tawm xeb tau raug tsim. Lawv yog raws li cov khoom uas yaj cov hlau oxide tsim nyob rau saum npoo ntawm cov hlau collapsing. Cov tshuaj ntxuav hauv tsev yog npaj raws li hauv qab no:

• dej - 300 ml;
• ammonium - 50 g;
• 40% formalin - 250g;
• caustic soda lossis caustic soda - 50 g.

Tom qab sib tov cov khoom xyaw, lawv yuav tsum tau diluted nrog ib liter dej. Muab tso rau hauv cov tshuaj hlau ntsiab lus uas tau undergonecorrosion (tsis haum rau kev kho deg). Tawm rau 15-40 feeb, qee zaus saib cov txheej txheem. Tshem cov khoom tam sim ntawd tom qab xeb ploj. Tom qab ntawd yaug zoo hauv dej kub thiab so qhuav. Original zoo thiab tej yam ntuj tso metallic luster guaranteed.

Anti-xeb acids

Nws paub tias cov kua qaub muaj peev xwm ua kom yaj ntau cov tshuaj lom neeg. Hydrated hlau oxide yog tsis muaj kev zam. Rau kev ua kom huv si zoo, ib qho yuav tsum siv rau cov kua qaub uas muaj zog, uas yog hydrochloric, sulfuric thiab orthophosphoric. Muaj tseeb, koj yuav tsum tsis txhob siv cov tshuaj ntshiab: lawv yog caustic dhau lawm. Rust acid yuav ua haujlwm zoo yog tias koj ntxiv ib qho inhibitor rau nws - ib yam khoom uas ua rau cov tshuaj tiv thaiv qeeb. Ib qho pheej yig tshaj plaws yog urotropin.

Daim ntawv qhia no yooj yim heev: koj yuav tsum noj ib qho ntawm cov kua qaub uas tau piav qhia thiab dilute nws nrog dej los tsim 5% kev daws. Tom qab ntawd ntxiv ib qho inhibitor ntawm tus nqi ntawm 0.5 grams ib liter ntawm kua. Qhov saum npoo yog kho nrog cov khoom tsim tawm thiab sab laug rau ib pliag. Hydrochloric, sulfuric lossis phosphoric acid tuaj yeem yooj yim tiv nrog txoj haujlwm. Qhov twg mus yuav ib qho inhibitor? Yog tias nws tsis nyob hauv khw thiab hauv khw tshwj xeeb, siv daim ntawv qhia no:

• muab qos yaj ywm saum rau hauv ib lub thawv peb-liter (yuav tsum sau ib nrab ntawm nws ntim);
• sau kua qaub kom txog thaum stems npog;
• 20 feeb nquag do cov ntsiab lus;
• kua kua - thiab lub tshuab nqus hlau yog npaj.

Phosphoric Acid Cleaner

Kev daws,Raws li phosphoric acid, nws tiv thaiv xeb hauv txoj kev muaj txiaj ntsig zoo. Cov cuab yeej hloov cov xeb txheej rau hauv cov txheej txheem ruaj khov. Dab tsi concentration yuav tsum yog phosphoric acid? Yuav qhov twg? Koj tuaj yeem nrhiav cov kua qaub, suav nrog phosphoric, hauv cov khw muag tshuaj tshuaj lossis chaw ua haujlwm. Txhawm rau npaj cov kev daws teeb meem zoo uas hloov cov hydrated hlau oxide rau hauv cov txheej txheem hlau, nws raug nquahu kom siv 15% lossis 30% aqueous tov ntawm phosphoric acid. Cov khoom uas tshwm sim yog siv nrog txhuam los yog rab phom thiab sab laug kom qhuav tag.

Lwm txoj hauv kev zoo ntawm kev daws "cov plaub hau liab" raws li phosphoric acid yog daim ntawv qhia no:

• butanol - 5 ml;
• tartaric acid - 15 ml;
• phosphoric acid - 1 l.

Vim li cas phosphoric acid thiaj li cuam tshuam rau xeb? Txhua yam tau piav qhia yooj yim hauv cov ntsiab lus ntawm chemistry: nws hloov cov hlau oxide rau hauv phosphate, uas tsim ib hom yeeb yaj kiab rau saum npoo ntawm cov hlau uas tiv thaiv nws.

Lwm txoj kev ntawm kev raug tshuaj lom neeg

Dab tsi lwm yam tshuaj tuaj yeem tshem tawm xeb? Tej zaum txoj kev yooj yim dua yuav yog cov cuab yeej xws li:

• sib tov ntawm kua paraffin (los yog roj vaseline) thiab lactic acid nyob rau hauv ib tug ratio ntawm 2: 1;
• zinc chloride (5 g) thiab cream ntawm tartar (0.5 g) yaj hauv 100 ml dej;
• turpentine lossis kerosene rau me me corrosion.

Txhua txoj kev no yog qhov zoo rautshem tawm cov xeb ntawm cov hlau ntawm cov tshuab thiab lwm yam khoom los ntawm "tsis yog-tsev" hlau. Rau kev siv hauv tsev, muaj ntau txoj hauv kev yooj yim dua thiab pheej yig dua rau kev tshem cov quav liab liab:

• ntses roj - siv rau xeb thiab tawm mus ib ntus;
• Kev sib tov ntawm citric acid thiab vinegar nyob rau hauv sib npaug zos proportions yuav tshem tawm ntawm corrosion nyob rau hauv lub chav da dej thiab xeb stains ntawm khaub ncaws, cov khoom yog thov rau 20 feeb, tom qab uas lub nto yog ntxuav nrog ib tug tawv daim txhuam cev;
• ua ib lub slurry ntawm baking soda (los ntawm kev ntxiv dej rau nws) thiab siv rau cov hlau nto, tawm rau ib teev, ces yaug;
• oxalic acid daws: 6 tsp. dissolve nyob rau hauv 300 ml ntawm dej, dipped lub rusted hais rau hauv lub resulting kua rau ib nrab ib teev;
• Coca-Cola yog ib qho zoo tshaj plaws xeb tshem tawm ua tsaug rau nws cov ntsiab lus phosphoric acid.

txoj kev tiv thaiv

Tshem tawm xeb ntawm hlau yog qhov ntev thiab tsis yog txheej txheem yooj yim tshaj plaws. Kev xeb tuaj yeem zam tau los ntawm kev siv qee txoj kev uas tiv thaiv qhov chaw los ntawm kev puas tsuaj. Nov yog qee cov zaub mov muaj txiaj ntsig los tiv thaiv xeb:

• paraffin lossis siv quav ciab (20 g) tov nrog roj av (40 ml), qhov kev daws teeb meem yog cov cuab yeej zoo tshaj plaws los tiv thaiv cov cuab yeej siv ntoo los ntawm corrosion;
• wax lossis paraffin (10 g) thiab kerosene (30 ml) yuav tiv thaiv xeb ntawm cov khoom siv hlau polished.

Kom tsis txhob "redness", koj yuav tsum tau saib xyuas cov khoom zoo: zam nws cov dej noo ntau dhau,raws sij hawm ntxuav ntawm av thiab hmoov av. Ntau cov txheej tiv thaiv corrosion tau tsim thiab tuaj yeem pom hauv cov khw muag tsheb.

Xeb tshem tawm yog cov tshuaj caustic uas yaj qhov teeb meem lossis hloov mus rau hauv cov yeeb yaj kiab tiv thaiv. Nws yog ib qho tsim nyog yuav tsum nco ntsoov tias txhua yam kev kho mob (hauv tsev lossis khw muag khoom) yog tshuaj lom rau tib neeg thiab hlau. Siv cov lus qhia thiab kev ceev faj yuav tsum tau ua raws li nruj me ntsis kom tsis txhob muaj kev puas tsuaj rau tawv thiab hlau nto.
