Hlau xim rau cov xeb xeb: kab ke, hom, yam ntxwv, daim ntawv thov thiab kev txheeb xyuas

Thaum ua tiav kev kho vaj tse, ntau zaus nws yuav tsum fim cov xim hlau. Ib qho teeb meem loj rau hauv rooj plaub no yog hais tias cov hlau tau oxidize thaum raug rau ya raws ntawm nws qhov chaw. Yuav kom tshem tawm cov xeb, nws yog ib qhov tsim nyog rau kev kho kom huv si, tom qab lub xim rau cov hlau yuav raug siv rau cov hlau hauv kab xeb tiv thaiv xeb, uas yog piav qhia nram qab no.

Tshawb Fawb

Cov kev tswj no yog qhov teeb meem, thiab qee cov qauv tsim tsis muaj rau cov kab xeb. Yuav kom ntseeg tau tias txoj haujlwm no, cov neeg ua lag luam tau saib xyuas tsim cov xim xeb uas siv tau los ua cov hniav coatings. Cov keeb no yog niaj hnub, lawv muaj ntau yam kev siv.

Kev txheeb xyuas cov xim thev duab ntawm corrosion

Cov xim rau hlau hauv rust anticorrosive possesses txheej zoo, ntawm lawv cov neeg tau txais kev pab:

• Tau ntawm kev tso npe ncaj qha rau xeb;
• Kev tsim ntawm kev tiv thaiv ntawm cov hlau, uas ua rau av thiab dej;
• Zoo zais fais fab, siab adhesion;
• Anticorrosive durability;
• Nreeb qhuav;
• Kev nplua nuj ntawm cov xim.

Txawm li cas los xij, nws yog ib qho tseem ceeb ntawm cov kev tsis txaus siab, ntawm lawv, cov neeg tau txais kev pab cuam nco ntsoov tsis muaj peev xwm pleev xim cov khoom uas yuav tsum tau rhuav txog li 150 ° C thiab siab tshaj thaum ua haujlwm. Ntawm lwm yam, raws li cov neeg muas zaub, tom qab tha xim sab nrauv yuav tsum tsis txhob nkag mus rau hauv dej los yog khoom noj.

Hom ntawm cov xim tsev rau xeb

Yog tias koj xav tau ib qho xim anticorrosive rau xeb, koj yuav tsum paub koj tus kheej nrog nws cov hom. Yuav kom ua tiav cov nyhuv ntawm qhov kev kho mob, nws yog qhov yuav tsum nkag siab txog cov kev siv ntawm cov ntawv sau rau xeb. Cov khoom sib xyaw ua ke no cais tawm raws li hom khoom loj, qhov siab tshaj plaws, thiab qhov ntau ntawm cov khoom. Piv txwv, nyob rau hauv kev ua lag luam koj tuaj yeem pom cov xim dej, uas muaj phosphoric acid. Rau lawv koj tau them qhov tsawg, tab sis qhov ruaj ntseg ntawm qhov chaw mus rau qhov chaw yuav tsawg. Cov lwm manufacturers muaj thiab ob-tivthaiv compositions, cov khoom xyaw no ntxiv rau epoxy resins, xeb inhibitors , thiab polyurethanes. Xim rau hlau ntawm xeb xeb xaim kuj tuaj yeem yog:

• Epoxy;
• Roj;
• Alkyd;
• Acrylic;
• Rauj.

Epoxy tebchaw yog lom, yog li lawv siv tsis tau rau hauv lub neej txhua hnub. Lawv yog cov haum rau rhuab hlau teeb. Qhov muaj pes tsawg cov roj sib tov muaj roj cov roj thiab ziab roj ziab. Cov dej ntws tom qab ziab yuav ua rau yus tsis tuaj yeem ua rau kub ntxhov siab. Yog hais tias cov khoom yog ua nyob rau hauv lub qhib cua, lub xeb tiv thaiv ntawm cov roj xim rau lub caij nplooj zeeg, yog li no tebchaw pom zoo rau kev siv nyob rau hauv tsev. Alkyd xim rau hlau rau xeb xeb npaj rau galvanized hlau, nws yog flammability, ces nws yuav tsum siv tsis tau rau rhuab lug. Daim ntawv thov yuav yooj yim heev, vim tias qhov sib tov muaj qhov siab ntawm kev nplua.

Zuag qhia kev pleev xim rau cov xeb

Ntawm kev muag khoom, koj tuaj yeem nrhiav acrylic xim, uas yog tsim rau cov khoom siv ua kom sov siab. Nws tuaj yeem siv rau cov cua sov ntsiab ob sab hauv thiab sab hauv tsev. Muab cov rusted hlau rov qab rau luv luv, koj tuaj yeem siv ib qho xim tshwj xeeb rau xeb, uas muaj peb yam khoom. Cov txheej txheem nrog cov dej sib tov no yuav zoo dua, cov ntaub ntawv ntawm cov xim muaj peev xwm nqa tau nyob rau hauv ib lub sij hawm luv luv thiab txawm nyob rau qhov tsis kho saum npoo. Ntawm cov khoom xyaw muaj cov khoom coj los tiv thaiv thiab cov resins. Cov xim nrawm nrawm sai sai, thiab tom qab kawm tiav ntawm theem no nws yuav muaj peev xwm tiv thaiv cov hlau rau 8 xyoo.

Rauj xim peev xwm ua tau ib tug ntxhib nto nrog ib tug nws yog xim hlau ci. Ntawm cov khoom xyaw muaj alkyds, epoxides, txhuas hmoov thiab acrylic. Rauj sib tov siv tau rau cov hlau uas tsis yog ferrous, thiab ib qho qauv ua ntej daim ntawv thov siv tsis tau. Thawj txheej pabcuam raws li tus qauv, thaum lub txheej thib ob yog anticorrosive. Tab sis qhov thib ib yog siv los ua ib qho nqaij npuas. Nws tsis tuaj yeem tiv thaiv cov hniav uas muaj xim rau xim, uas yuav tsum tau rhuab thaum ua haujlwm saum 150 tawm C.

Daim ntawv thov nta

Anticorrosive xim rau co, cov kev siv ntawm cov uas yuav tsum tau nqa tawm raws li cov lus qhia ua ntawv thov mus rau lub npaj nto. Lub substrate yuav tsum tau ntxuav, degreased thiab qhuav, freed los ntawm lub qub txheej ntawm xim nrog emery los yog txhuam rau hlau. Ntawm qhov loj unevenness tus tswv tau tshem ntawm cov crusher. Cov kws txawj pom zoo kom ua lub hauv paus priming, uas ua rau kev zoo ntawm kev nplua, ua cov txheej txheem ntau. Yog tias koj siv cov xim pleev xim rau hauv av, ces yuav tshem tawm cov kauj ruam no.

Cov kauj ruam tom ntej yog daim ntawv pleev xim, thaum nco ntsoov tias qhov kub ntawm qhov chaw yuav tsum txawv li ntawm 20 ° C, cov av noo yuav tsum yog 80%. Cov xim yog thinned thiab diluted nrog ib tug hnyav, siv tus 9: 1 ratio. Nws tsis pom zoo kom siv ntau tshaj peb txheej, qhov kev tshem tawm yuav tsum tsis txhob yaj nrog nitrocellulose sib tov. Rau kev ua haujlwm, koj tuaj yeem siv phom cov tshuaj tsuag, tos ntawm cov khaubncaws sab nraud pov tseg rau 15 feeb.

Cov yam ntxwv ntawm cov xim muaj hlau HV-0278

Yog tias koj xav paub txog cov khoom muaj xim rau cov hlau muaj nyob rau qib xeb-qib HV-0278, ces koj yuav tsum paub txog koj tus kheej nrog cov lus qhia hauv qab no. Nkaum hwj chim tsis pub tshaj ntawm zaj duab xis yog los ntawm 60 mus rau 120 g / m ^2, qhov kawg tus nqi yuav yog nyob ntawm seb cov xim. Lub hardness ntawm zaj duab xis los ntawm pendulum yog 0.15 mm. Qhov coefficient ntawm kev hloov pauv ntawm xeb yog 0.7, qhov ua haujlwm ntawm cov yeeb yaj kiab los ntawm txoj haujlwm ntawm kev daws ntawm sodium chloride yog 72 teev. Cov tshuaj no yog npaj raws li specification 2313-174-21743165-2000.

Kev xyuas ntawm HB-0278

Raws li cov neeg siv, kev tiv thaiv mus ntev nrog XB-0278 tuaj yeem ua kom tsuas yog tias cov hlau tsis tuaj yeem nrog kev sib txuas hluav taws xob, cov khoom siv hluav taws xob thiab cov pa oxygen. Lub rusting center yuav raug rho tawm tag nrho tom qab daim ntawv thov ntawm cov xim. Raws li lwm qhov kom zoo dua tus piav qhia ntawm tus neeg laus, nws tsis muaj kev txwv rau cheeb tsam thiab kev ua haujlwm. Ntawm lwm yam, qhov tiv thaiv txheej txheem muaj cov khoom zoo nkauj. Qhov txheej yuav muaj xim nyob rau hauv cov xim sib txawv. Muaj ib qho ntxiv rau cov khoom siv xws li xim rau hlau thiab xeb, yam ntxwv. Qhov nws xaiv yog qhov tseeb yog tias koj xav tau los tiv thaiv ib lub thawv ntoo, ib lub ru tsev, muaj fais fab lossis lwm hom tsev. Cov xim no yooj yim rau kev thov. Koj tuaj yeem ua haujlwm rau koj tus kheej. Raws li cov neeg yuav khoom, tus tswv yuav tsum siv tus kheej cov khoom tiv thaiv, kom qhov chaw muab kev pabcuam rau hauv qhov chaw.

Xaus

Qhov xim uas tau hais los saum toj no rau cov hlau hauv xeb yog anticorrosive, tus nqi yog 118 rubles. Ib qhov hnyav, qhov txawv ntawm nws rab peev xwm los tiv thaiv kev tsim kho thiab lwm yam ntawm kev ua los ntawm kev tsis zoo ntawm lwm qhov chaw. Cov ntaub ntawv sau saum toj no tau tuav cov kev ua tau zoo hauv chaw kub dav: -50 rau + 80 ° C. Qhov no kuj muaj tseeb yog hais tias tus qauv yog tshwm sim kub siab hloov.
