Kev ua tiav ntawm cov hlau saum npoo yog nyob ntawm qib ntawm lawv kev tiv thaiv thiab tiv thaiv rau lwm yam kev cuam tshuam. EP-773 txha hniav laus tsis xeb yuav pab kom lawv muaj zog thiab ua haujlwm ntev. Tau kawm txog cov yam ntxwv ntawm cov khoom siv thiab ua raws qee txoj cai ntawm kev thov, koj tuaj yeem tsim tsis tsuas yog txhim khu kev qha, tab sis kuj yog txheej zoo nkauj.

Teem caij

Cov muaj pes tsawg leeg ntawm cov tshuaj tiv thaiv kab mob "EP-773" thiab thev naus laus zis ntawm nws cov khoom tsim tau txiav txim siab los ntawm cov qauv ntawm GOST 23143 83. Raws li cov ntaub ntawv raug cai, cov khoom tau tsim los ntawm epoxy resin "E-41" nrog rau suav nrog ntawm cov fillers thiab ntau yam xim. Cov xim thiab cov kua roj vanish yog ob qho kev tiv thaiv-cov xim raug tshem tawm yog sib xyaw nrog amine-type hardener tam sim ua ntej zas xim.

Kev siv tshuaj yog vim nws cov khoom tiv thaiv.

Nws tiv thaiv kom tsis txhob raug cov hlau:

• cov av noo siab;
• roj daws;
• ntsev ntsev;
• cov khoom sib xyaw xws li roj av thiab nws cov analogues.

Cov tshuaj tiv thaiv corrosive muaj feem cuam tshuam rau kev siv ntev ntawm cov hlau thiab cov hlau tsis muaj hlau, nrog rau cov pob zeb ua haujlwm tom qab ua ntej. Hauv tsev, nws tuaj yeem siv los ua cov txheej txheem cov kav dej, cov kav dej sab hauv thiab sab hauv, ntau yam qauv tsim thiab khoom siv. Ib qho ntxiv, nws yog qhov kev xaiv pheej yig tshaj plaws rau kev tiv thaiv txheej.

Khoom

Cov xim muaj txiaj ntsig zoo tiv thaiv cov hlau hlau los ntawm cov cua sov cuam tshuam los ntawm alkali vapors ntawm txhua qhov kev xav, qhov tshwm sim hauv huab cua, hloov pauv kub, hnav sai vim yog kev nyuab siab.

Cov hniav muaj cov yam ntxwv tseem ceeb hauv qab no:

• tsim cov matte thiab semi-matte tiav;
• muaj qhov ua haujlwm viscosity ntawm 25-60, uas tso cai rau nws siv ob qho tib si manually thiab los ntawm kev txau;
• kev pom kev zoo yog ua tiav nrog tsuas yog ob txheej nrog tuab tsis ntau tshaj 25 microns;

• cov khoom muaj qhov ua tau zoo tshaj plaws rau hlau thiab feem ntau yog siv rau txheej txheej, tab sis tuaj yeem thov yam tsis muaj nws;
• Kev ziab zaum kawg yuav tshwm sim hauv ib hnub, tab sis nyob rau qhov kub uas tsim los ntawm qhov kub, qhov ziab zaum kawg tsuas yog siv sijhawm 2 teev xwb;
• txheej txheej muaj qhov ua kom siab, nrog khoov ntawm 5 hli;
• rau ib txheej txheej, kev siv ib square meter ntawm thaj chaw yog qhov kev lag luam yooj yim thiab tsis tshaj 75 grams ntawm cov xim sib xyaw.

Cov xim tha xim muaj nyob hauv ob qho xim yooj yim - ntsuab thiab qab zib, tab sis koj tuaj yeem xaiv ib qho ntxoov ntxoo ntawm zas xim kom xaj. Qhov tseeb, nws yuav tsum nco ntsoov tias thaum kis rau tib cov poov tshuaj alkali, cov suab thaj xim av tsis ruaj khov thiab tsim lub sijhawm uas plaub zaug tsawg dua li ntawm cov xim daj ntsuab.

Tom qab ziab, cov xim, raws li txoj cai, tsis hloov pauv los ntawm qhov ntxoov ntxoo uas tau xaiv, thiab cov yeeb yaj kiab du nyob rau saum npoo yam tsis muaj kev cuam tshuam txawv teb chaws.

Kev npaj cov tshuaj

Yog tias ua haujlwm sab hauv tsev, lub ntim nrog cov xim tau khaws cia hauv chav sov li ntawm ib hnub.

Rau kev npaj cov xim sib tov, cov theem ntawm kev npaj, kev saib xyuas ntawm qhov sib piv thiab kev sib xyaw kom huv yog qhov tseem ceeb:

• ua ntej, koj yuav tsum ua kom ntseeg tau tias ib qho kev tshem tawm ib qho yog homogeneous hauv cov qauv thiab ntim, nws yuav tsum tau sib xyaw kom huv txhawm rau txhawm rau tshem tawm cov nag lossis daus ntawm cov khoom pov tseg;
• tom qab ntawv tus hardener No. 1 "DETA" tau qhia rau hauv kev daws teeb meem, suav nrog cov lej uas tau qhia hauv cov lus qhia;

• nws yog qhov tsim nyog kom sib tov sib xyaw rau 10 feeb kom txog thaum ua tiav homogeneity, tom qab ntawd sawv ntsug rau lwm 40 feeb thiab do dua kom nce kev sib kis thiab txhim kho qhov tsos ntawm cov txheej;
• tom qab ntsuas qhov viscosity rau rab phom (nrog lub taub me me ntawm 4 hli, nws yuav tsum tsis pub ntau tshaj 16 s), yog tias tsim nyog, koj tuaj yeem dilute qhov muaj pes tsawg leeg nrog qhov hnyav "R-4", 646 lossis toluene;
• kev sib xyaw ua tiav yog siv cov xim pleev xim, laum lossis cov khoom sib tov tsim.

Yog tias kev daws teeb meem tsis muaj homogeneous txaus, thiab qhov no qee zaum tshwm sim vim kev sib xyaw hauv cov nruas ntim, cov xim pleev xim yuav tsis qhuav zoo nyob hauv qee qhov chaw. Kho qhov teeb meem no nyuaj dua li tiv thaiv nws. Ib qho ntxiv, qhov no ua rau muaj kev faib tawm tsis sib luag ntawm cov tawv tawv, uas ua rau muaj zog, ua kom tuab ua ntej. Qhov no yog vim li cas thiaj xav tau lub tais tshwj xeeb qhib rau nplawm.

Nws yuav tsum tau nco ntsoov tias kev pleev xim yuav tsum tsis txhob nqa tawm ntawm qhov chaw ntub dej. Lub hauv paus yuav tsum tau primed, tshwj xeeb tshaj yog thaum siv nyob rau hauv ib puag ncig txhoj puab heev, thiab yuav tsum tau qhuav ua ntej.

Hlau txheej tu

Cov kauj ruam no yog qhov tsim nyog raws li nws pab txhawm rau ua kom pom qhov ua tau zoo ntawm cov khoom siv rau cov hniav.

Cov haujlwm hauv qab no tau npaj tseg:

• tu los ntawm nplai, xeb, av thiab lwm yam me me ntawm cov khib nyiab - rau cov laj thawj no, cov xeb hloov pauv, daim ntaub txhuam hniav, txhuam tshwj xeeb nrog xaim xaim rau hlau, chav ua haujlwm xuab zeb tau siv;
• sib tsoo thiab tshem tawm cov hmoov av hlau;
• degreasing roj thiab greasy stains nrog cov kuab tshuaj.

Txhawm rau ua ntej ntxiv, koj yuav xav tau EP-0020 lossis EP-0010 cov khoom sib xyaw tshwj xeeb tsim los rau xim epoxy. Ob lub tsho loj txaus rau cov xim pleev xim tom ntej. Cov pob zeb ua ke tau kho nrog cov tshuaj tshwj xeeb "Sibton EP-Primer".

Cov cai tswjfwm

Hauv lub neej txhua hnub, pleev xim nrog txhuam thiab cov menyuam tau siv ntau dua, tab sis rau kev ua haujlwm ntau, nws yog qhov ntse siv cov cuab yeej siv pneumatic. Kev pleev xim yog ua tiav ntawm qhov kub ntawm +15 txog +35 degrees thiab av noo nruab nrab txog li 80%. Qee qhov xwm txheej, ua kom khov hauv qhov sov mus txog -10 degrees raug tso cai, tab sis kev sib xyaw yog nqa tawm ntawm chav sov. Tab sis qhov no yog qhov tsis xav tau, vim nws nce lub sijhawm ziab kom txog li ib lub lim tiam.

Feem ntau EP-773 txha hniav laus tau thov hauv ob txheej, txawm hais tias muaj xim kuj tseem muab los ua txheej ntau txheej.

Txhua daim ntawv thov tom ntej yuav tsum ua qhov sib nrug ntawm ib hnub, txij li nws yog lub sijhawm no uas txheej txheej qhuav tag. Los ntawm txoj kev, hlau tuaj yeem ua kom qhuav ob qho tib si thiab kub siv cov cua sov cua sov thiab lwm yam khoom siv. Cov cua sov yuav tsum yog li +120 degrees.

Koj yuav tsum tsis txhob chim siab thaum twg, tom qab qhov ziab qhuav, pom cov yeeb yaj kiab nplaum ntawm cov hlau kho - qhov no tsis yog qhov tsis xws luag, tab sis nws tshwm sim vim muaj cov yas yas. Nws yog txaus los ntxuav tawm cov txheej txheej greasy nrog dej xab npum, thiab cov txiaj ntsig sab no yuav raug tshem tawm.

Thaum ua haujlwm nrog cov xim thiab cov kua roj vanish, ib tus yuav tsum tsis txhob hnov qab txog kev ntsuas tus kheej kev nyab xeeb . Nws yog qhov tsim nyog los ua cov txheej txheem ua haujlwm hauv kev tiv thaiv khaub ncaws, hnab looj tes, lub npog ntsej muag roj lossis lub tshuab ua pa thiab muaj cov cuab yeej tsim nyog rau kev tua hluav taws nyob ze.

Rau cov uas txiav txim siab siv cov khoom no, peb tuaj yeem pom zoo yuav tsuas yog cov khoom lag luam zoo los ntawm cov chaw tsim khoom ntseeg, piv txwv li, los ntawm PFC Spektr kev lag luam, uas tau lees tias cov khoom lag luam zoo heev uas tuaj yeem ua kom siv tau ntev ntawm ntau hom hlau cov qauv.
