Xeb remover: xaiv, daim ntawv thov

Xeb - ib qho "tus kab mob" ntawm hlau. Cov check ntau yam ntaub ntawv nyob ib ncig ntawm peb. Lawv yuav siv los tsim lub tsev cov khoom siv, tsheb, huab cua thauj, thiab ntau npaum li cas. Tag nrho cov muaj zog Symptoms kuj ua los ntawm cov hlau. Tab sis ntawm no yog qhov teeb meem: lub sij hawm, muaj ntau yam ntawm lawv raug mus oxidation - corrosion. Material puas nyob rau hauv tus ntawm ib puag ncig, thiab cov qauv pib deteriorate. Yuav ua li cas mus cawm ib tug hlau los ntawm tej yam kev tuag? Yuav ua li cas xeb remover los xaiv? Cia peb kawm nyob rau hauv no tsab xov xwm.

Tshem tawm ntawm lub teeb kab mob sib kis

Cov ua ntej lawm cov xeb, qhov yooj yim dua nws yog los nrog nws. Yog hais tias qhov kev puas tsuaj yog tsis heev sib sib zog nqus mus rau hauv lub hlau velos txaus mus rau chaw uasi mus rau ib tug cov neeg kho tshuab ntxuav txoj kev. Ua li no, koj yuav tau kho tus nto nrog ib tug txhav txhuam. Sanding tuskheej av thiab txheej xa hlau los ntawm ntxiv hais tawm "kab mob."

Nws yuav tsum tau muab sau tseg tias kauj ruam ntawm cov neeg kho tshuab kev kho mob muaj ntaub ntawv rau tshwj kom txhob tsaug ingrained xeb ua ntej koj thov cov tshuaj mus cuag qhov zoo tshaj plaws tshwm sim. Koj yuav teev ib tug loj ntwav txhuam ntoo raws li ib tug txhav txhuam.

Avtoochistitel

Zoo xeb remover - nqus tsev vacuum tsheb hlau. Qhov cuab yeej no yog muaj: nws muaj peev xwm yuav tau nyob tej tshwj xeeb nyob rau hauv cov khoom rau cov khw tsheb. Ua ntej thov kev nws yog pom zoo los ntxuav lub saum npoo nrog ib tug txhav txhuam, cuam tshuam los ntawm tus kab xeb. Ces cheeb tsam coated nrog cov neeg ua hauj 5 millimeters tuab, thiab tso cai rau sawv ntsug rau ib tug ob peb feeb. Ces residues yuav tsum tau rinsed thiab qhuav nto rau dryness. Yog hais tias lub xeb yog tsis tau kiag li lawm, rov hais dua cov txheej txheem.

Nws yuav tsum tau nco ntsoov hais tias hais tias muaj xeb remover lom. Feem ntau qhov no acid ingress uas ua rau ntawm daim tawv nqaij burn. Ua hauj lwm tsim nyog hnav tiv thaiv cov hnab looj tes, tsom iav thiab qhov ncauj. Tsis tas li ntawd, nws yuav tsis tau superfluous ua tib zoo nyeem cov lus qhia rau kev siv thiab kev nyab xeeb yuav tau ceev faj.

makeshift tshuaj

Raws li ib tug tshwm sim, neeg 's thwmsim tsim ib tug ntau ntawm "lub tsev" zaub mov txawv kev tshem tawm cov xeb. Lawv yog raws li nyob rau hauv cov tshuaj uas yaj hlau oxide tsim rau ntawm qhov chaw ntawm lub collapsing hlau. Qhob kua xeb remover yog npaj raws li nram no daim ntawv qhia:

• dej - 300 ml;
• ammonium - 50 g;
• 40% formalin - 250 g;
• caustic dej qab zib los yog sodium hydroxide - 50 g

Tov cov khoom xyaw, lawv yuav tsum tau diluted nrog ib tug liter ntawm dej. Cov tshuaj twb muab tso rau lub hlau ntsiab, uas yog raug rau xeb (nto kho mob tus neeg saib xyuas yuav tsis ua hauj lwm). Cia rau 15-40 feeb, Qee zaus saib tus txheej txheem. Tshem tawm cov qhov chaw tam sim ntawd tom qab lub disappearance ntawm xeb. Ces zoo ntxuav nyob rau hauv dej kub thiab qhuav mus dryness. Thawj cov tsos thiab tej yam ntuj tso nws yog xim hlau ci guaranteed.

Acid thaiv tus kab xeb

Nws yog lub npe hu hais tias cov acids yog tau yaj ntau tshuaj tebchaw. Lub hydrated hlau oxide yog tsis muaj exception. Rau qhov zoo purification yuav tsum uasi rau muaj zog acids, wherewith yog hydrochloric, sulfuric, thiab phosphoric. Txawm li cas los, siv lub huv si daws yog tsis: lawv yog cov heev tart. Acid xeb ua hauj lwm kom zoo, yog hais tias peb ntxiv inhibitor - ib yam khoom uas slows cia ib tug tshuaj cov tshuaj tiv thaiv. Ib qho ntawm feem siv tau yog methenamine.

Lub daim ntawv qhia yog yooj yim heev: nws yog tsim nyog los noj ib yam ntawm cov tau piav acids thiab dilute nws nrog dej rau 5% tshuaj. Ces ntxiv inhibitor ib 0.5 grams ib liter ntawm kua. Deg yog kho kom tau nyiaj thiab tawm nws ib pliag. Cov hauj lwm yooj yim tiv hydrochloric, sulfuric los yog phosphoric acid. Qhov twg mus yuav ib tug inhibitor? Yog hais tias nyob rau hauv lub lag luam thiab nyob rau hauv tshwj xeeb khw muag khoom noj tsis, siv no daim ntawv qhia:

• qos saum nteg nyob rau hauv peb-liter hub (yuav tsum tau sau ib nrab ntawm nws volume);
• ncuav acid los npog lub stems;
• 20 feeb koom agitate tus txheem;
• ntws lub kua - cov hlau nqus tsev vacuum thiab npaj txhij.

Txhais tau hais tias phosphoric acid

Ib tug tov, ua rau lub hauv paus ntawm phosphoric acid, combats xeb heev ib qho kev zoo yam. Txhais tau tias converts xeb check txheej txheej. Thaum dab tsi concentration yuav tsum phosphoric acid? Qhov twg yuav nws? Nrhiav acids, xws li phosphoric acid, yuav ua tau nyob rau hauv lub khw los yog muaj-Science News for KIDS departments. Yuav kom npaj ib tug zoo tshuaj, hloov hydrated hlau oxide nyob rau hauv lub khoom txheej ntawm cov hlau, nws yog pom zoo kom siv ib tug 15% los yog 30% aqueous orthophosphoric acid tshuaj. Cov uas ua neeg sawv cev yog thov los ntawm txhuam los yog tshuaj tsuag rab phom thiab tso cai rau qhuav kiag li.

Lwm siv tau txoj kev ntawm combating "ryzhinoy" nyob rau lub hauv paus ntawm orthophosphoric acid yog ib daim ntawv qhia:

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

Yog vim li cas phosphoric acid thiaj muaj feem xyuam rau cov xeb? Tag nrho cov yooj yim piav qhia nyob rau hauv cov nqe lus ntawm Science News for KIDS: nws converts tus hlau oxide nyob rau hauv lub phosphate, uas tas ib hom ntawm ib tug zaj duab xis nyob rau hauv lub hlau nto uas tiv thaiv nws.

Lwm yam txoj kev tshuaj

Yuav ua li cas lwm cov ntaub ntawv yuav tsum tau ntse tso xeb? Tej zaum ib tug yooj yim txoj kev yuav cuab yeej xws li:

• sib tov ntawm cov kua paraffin (los yog kua petrolatum), thiab lactic acid nyob rau hauv tus piv 2: 1;
• yaj nyob rau hauv 100 ml ntawm dej, zinc chloride (5 g) thiab qab zib ntawm cov tartar (0.5 g);
• Turpentine los yog kerosine rau negligible corrosion.

Tag nrho cov kev zoo kev tshem tawm cov xeb rau hlau machinery thiab lwm yam hais txog lub "non-domestic" hlau. Siv hauv tsev, muaj ntau ntau ntau yam yooj yim thiab pheej yig txoj kev tshem cov quav hniav qhiav:

• ntses roj - yog thov kom xeb thiab tawm rau ib tug thaum;
