Xim Epoxy Uas Siv Dej Ua Haujlwm Zoo: Xim Tiv Thaiv Kev Xeb

* Cov Khoom Muaj pes tsawg leeg:

Cov xim epoxy ua los ntawm dej yog ob yam khoom, ua tau zoo heev, thiab tiv thaiv kev xeb rau ib puag ncig, nws muaj cov epoxy resin uas hloov kho tshiab rau hauv dej, cov xim tiv thaiv xeb, cov khoom sau, cov khoom ntxiv thiab cov dej deionized, thiab lwm yam. Thiab nws muab cov nplaum zoo heev, tiv taus tshuaj lom neeg, thiab tiv taus xeb ntawm cov xim epoxy ib txwm muaj nrog rau cov txiaj ntsig zoo ntawm cov xim dej, xws li kev nyab xeeb ib puag ncig thiab VOC qis heev. Nws yog ib qho kev xaiv tseem ceeb rau kev tiv thaiv kev xeb xws li nkoj, choj, thiab cov qauv hlau.

* Cov yam ntxwv ntawm cov khoom:

● Kev tiv thaiv ib puag ncig txheej, siv dej ua thinner, VOC qis heev, kev nyab xeeb thiab ruaj khov cia thiab kev tsim kho, tsis kub hnyiab thiab tsis tawg.

● Kev ua tau zoo heev tiv thaiv xeb thiab tiv thaiv xeb.

● Kev nplaum zoo heev, tiv taus kua qaub thiab alkali zoo heev, tiv taus cov kuab tshuaj, thiab tiv taus huab cua zoo heev.

● Kev Tiv Thaiv Tshuaj: Cov xim pleev xim tuab thiab tiv taus xeb los ntawm dej, ntsev tsuag, roj, cov tshuaj tsis muaj zog thiab cov kua qaub.

● Muaj zog tiv taus kev laus ntawm cov khoom cuav, tiv taus dej zoo, yooj ywm ntawm cov xim pleev xim, tiv taus kev cuam tshuam zoo, thiab tiv thaiv cov khoom siv zoo heev.

* Daim Ntawv Thov Khoom:

Nws yog qhov tsim nyog rau kev tiv thaiv xeb nruab nrab thiab hnyav ntev ntawm cov qauv hlau thiab cov khoom siv kho tshuab hauv qhov chaw nruab nrab mus rau qhov chaw xeb hnyav, thiab kuj tseem siv tau rau cov chaw saib xyuas. Nws yog dav siv rau kev tiv thaiv xeb hauv kev lag luam hauv cov choj, cov tsev rau khoom hlau, cov qauv hlau hauv kev lag luam petrochemical, fais fab, thiab metallurgical, cov kav dej, cov thoob dej cia khoom (phab ntsa sab nraud), cov khoom siv txhawb nqa, thiab lwm yam kev siv hauv kev lag luam. Nws kuj tseem siv rau cov txheej tiv thaiv xeb hauv kev siv thauj mus los xws li cov tshuab chaw nres nkoj, cov tshuab tsim kho, cov tsheb lag luam, cov tsheb ciav hlau, cov thawv, thiab cov tsheb thauj khoom. Nws kuj tseem siv tau rau kev tiv thaiv xeb ntawm cov qauv sab hauv xws li chav cav nkoj, cov qauv loj, thiab cov thoob dej ballast.

* Kev Kho Mob Nto:

Yuav kom ntseeg tau tias zaj duab xis lo rau thiab tiv thaiv kev xeb mus sij hawm ntev, qhov chaw ntawm cov khoom siv yuav tsum tau ntxuav kom huv si kom tsis txhob muaj roj, xeb, nplai, xim qub, thiab cov khoom tsis huv ua ntej siv. Cov qauv kev npaj yuav tsum ua tau raws li cov hauv qab no.:

Txhua qhov chaw uas yuav pleev xim yuav tsum huv, qhuav thiab tsis muaj kuab paug. Ua ntej pleev xim, txhua qhov chaw yuav tsum ua raws li ISO_{8504: 2000}kev ntsuam xyuas thiab kev ua tiav tus qauv.

Cov hlau scaled raug blasted rau Sa_2.5qib, qhov roughness ntawm qhov chaw yog 30-75μm, lossis pickled, neutralized thiab passivated;

Cov hlau tsis muaj oxide blasted rau Sa_2.5qib, lossis txhuam rau St₃qib nrog lub log sib tsoo pneumatic lossis hluav taws xob elastic;

Cov hlau uas tau coated nrog cov xim pleev xim rau hauv chaw ua haujlwm yuav tsum tau muab tshem tawm cov xeb ob zaug, cov xeb dawb raug tshem tawm thiab txhuam kom txog thaum cov xim pleev xim puas lawm, cov xeb dawb thiab cov xeb dawb ntawm cov zinc hmoov primer yuav tsum tau muab tshem tawm.₃.

Lwm cov nto Cov khoom no yog siv rau lwm cov substrates, thov sab laj nrog peb lub chaw haujlwm kev tshaj lij.

Qhov chaw kho yuav tsum huv, qhuav, tsis muaj roj, tsis muaj plua plav, thiab pleev xim tsis pub dhau 6 teev tom qab xuab zeb kom tiv thaiv xeb ntawm qhov chaw.

* Cov ntaub ntawv kev siv:

Cov qauv kev ua tiav: HG/T 4759-2014

* Kev Tsim Kho:

Qhov kub ntawm lub substrate tsis qis dua 5 ℃, thiab tsawg kawg 3 ℃ siab dua qhov kub ntawm cov dej noo thiab qhov av noo yog <85% (qhov kub thiab av noo yuav tsum ntsuas ze ntawm lub substrate). Kev tsim kho raug txwv tsis pub ua thaum muaj pos huab, daus thiab cua hlob.

*Cov Kauj Ruam Tsim Kho:

Kauj Ruam 1: Kev Npaj Qhov Nto Ntawm Cov Khoom Siv (TusTus yuam sijKauj Ruam)

Qhov zoo ntawm kev npaj nto ncaj qha txiav txim siab qhov lo thiab lub neej ntawm cov xim pleev xim.

Cov nplaim hlau yuav tsum tau tshem cov roj tawm thiab tsis muaj xeb (rau Sa2.5 lossis St3 tus qauv) kom ntseeg tau tias cov nplaim hlau uas yuav pleev xim yuav tsum huv si, qhuav tag, thiab tsis muaj cov kuab paug xws li roj, roj, hmoov av, ntsev, nplai, thiab cov xim qub xoob. Tsis pub pom cov dej noo lossis cov dej noo.

Qhov chaw kho yuav tsum ua tau raws li tus qauv tsim qauv huv thiab qhov ntxhib, thiab yuav tsum pleev xim sai li sai tau kom tiv thaiv xeb rov qab los yog muaj kuab paug thib ob.

Kauj Ruam 2: Siv Primer

Yuav kom ntseeg tau tias muaj kev tiv thaiv xeb zoo dua, pom zoo kom siv ib txheej tiv thaiv xeb primer, thiab nws kuj txhim kho kev nplaum rau lub substrate.

Kauj Ruam 3: Siv Xim Epoxy Uas Muaj Dej

Tom qab qhib lub thoob, do kom sib npaug nrog lub tshuab hluav taws xob kom txog thaum cov xim thiab viscosity sib xws, maj mam nchuav cov khoom B (tus neeg sawv cev curing) rau hauv cov khoom A (xim), kom huv si raws li qhov sib piv teev tseg (los ntawm qhov hnyav). Tom qab do kom tag, cia cov khoom sib tov sawv rau 5-10 feeb kom tiav. thiab cov txheej sib xyaw siv tawm hauv 4 teev (lub neej lauj kaub). Tom qab ntawd txhuam / dov lossis tsuag, Airless spraying muab qhov ua tau zoo tshaj plaws thiab tsim cov xim zoo tshaj plaws. Yog tias koj muaj cov khoom siv thiab cov txheej txheem tshaj lij, nws yuav zoo tshaj plaws. Kev siv xim theoretical yog 0.2kg / m² / txheej. (Kev siv tiag tiag yuav txawv nyob ntawm qhov zoo ntawm qhov chaw, porosity, txoj kev siv thiab cov txheej txheem ua haujlwm.)

Lus Cim:

*Yog tias xav tau kev ua kom nyias nyias, muab dej deionized ntxiv rau raws li qhov viscosity thiab txoj kev siv (txhuam, dov, lossis txau). Kho qhov viscosity kom haum rau txoj kev siv.

* Qhov sib piv ntawm kev sib xyaw ntawm 5-20% los ntawm qhov hnyav. Kev ua kom nyias dhau yuav cuam tshuam tsis zoo rau kev tsim cov zaj duab xis, lub zog zais, thiab kev ruaj khov mus sij hawm ntev.

* Ua ntej siv txheej tom ntej, xyuas kom meej tias txheej dhau los tau kho tag nrho, huv si, qhuav, thiab tsis muaj txhua yam kab mob.

* Tsis txhob do hnyav heev kom tiv thaiv kom tsis txhob muaj npuas ntau dhau.

* Rov txheej dua lub sijhawm: Hauv qhov chaw muaj xeb me ntsis: 1 txheej ntawm primer +2 txheej xim nruab nrab + 2 txheej ntawm topcoat; nyob rau hauv cov chaw muaj xeb hnyav, nce qhov tuab ntawm txheej.

*Txoj Kev Tsim Kho:

Tshuaj tsuag: Tshuaj tsuag tsis siv cua lossis tshuaj tsuag los ntawm huab cua. Nws raug nquahu kom siv cov tshuaj tsuag tsis siv cua siab.

Txhuam/Dov: Yuav tsum ua tiav qhov tuab ntawm zaj duab xis qhuav uas tau teev tseg.

*Cov kev ceev faj:

▶ Qhov kub ntawm kev tsim kho yog 5 ℃ -35 ℃ (Kev hloov kho tshwj xeeb yog ua raws li cov yam ntxwv ntawm cov khoom, qhov av noo yog ≤85%.

▶ Ua kom muaj cua nkag tau zoo kom cov dej noo noo thiab cov xim pleev xim qhuav.

▶ Yuav tsum paub tseeb tias siv tau zoo thaum sib xyaw nrog cov xim uas muaj cov kuab tshuaj (pom zoo kom sim me me xwb).

(pom zoo kom kuaj ib cheeb tsam me me).

▶ Tiv thaiv kom tsis txhob khov thaum lub sijhawm khaws cia.

▶ Yuav tsum hnav cov khoom siv tiv thaiv thaum lub sijhawm xuab zeb

▶ Tsis pub ua vaj tse vim pos huab, nag, daus, cua thiab nag.

* Kev Cia Khoom thiab Lub Neej Tus Kheej:

▅ Khaws cia rau hauv qhov chaw txias, qhuav, thiab muaj cua nkag tau rau hauv tsev rau khoom ntawm qhov kub ntawm 5-35 ℃, tsis txhob cia khov thiab tshav ntuj ncaj qha;

▅ Lub neej ntawm cov khoom siv yog 12 lub hlis. Yog tias cov khoom uas khaws cia ntev tshaj lub sijhawm khaws cia, ces siv tau tom qab dhau qhov kev tshuaj xyuas.

*Pob khoom:

Xim: 20 Kg/Thoob; Tus neeg sawv cev kho: 4 Kg/Thoob los yog Kho Kom Zoo

Qhov hnyav sib xyaw ua ke = 5: 1
