Cov Tshuaj Pleev Xim Epoxy Tiv Thaiv Kev Xeb Uas Siv Dej (ob yam khoom)

* Kev Piav Qhia Txog Khoom:

Nws yog ob-txheej txheej, ua los ntawm cov dej epoxy resin, cov xim thiab cov khoom sau, cov neeg pabcuam, dej deionized thiab lwm yam.

* Cov yam ntxwv ntawm cov khoom:

● Tiv thaiv xeb thiab tiv thaiv xeb: Ntxiv cov xim tiv thaiv xeb kom tiv thaiv cov dej noo thiab cov pa oxygen, ncua kev xeb ntawm cov hlau substrates, thiab tsim nyog rau cov chaw noo noo;

● Cov yeeb yaj kiab muaj kev tiv thaiv dej zoo heev thiab kev ua haujlwm tiv thaiv xeb;

● Kev nplaum zoo heev: Cov khoom siv epoxy resin tuaj yeem lo rau ntau yam khoom siv (xws li hlau thiab pob zeb), daws cov teeb meem ntawm kev xuab zeb thiab kev ua kom lub hauv paus tsis khov;

* Daim Ntawv Thov Khoom:

Nws yog qhov tsim nyog rau kev tiv thaiv xeb thiab tiv thaiv xeb ntawm cov chaw xws li cov pob zeb ua vaj tse, hlau, galvanized ntawv, txhuas alloy, thiab lwm yam, thiab yog dav siv hauv kev tsim kho, choj, cov kav dej hauv av, cov khoom siv kev lag luam, cov khoom siv hydraulic, tshuaj lom neeg, cov khoom siv kho tshuab, kev tsim cov qauv hlau, cov chaw tsim hluav taws xob thermal, cov chaw tsim hluav taws xob nuclear, cov pej thuam cua thiab ntau yam roj, cov pa roj purity siab thiab cov tso tsheb cia tshuaj lom neeg organic.

* Cov ntaub ntawv kev siv:

Cov qauv kev ua tiav: HG/T4759-2014

* Kev Kho Mob Nto:

Yuav kom paub tseeb tias daim zaj duab xis lo rau thiab tiv thaiv 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.

* 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 kev 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 Cov Tshuaj 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 yuav tsum tau ua kom nyias nyias rau kev siv kom raug, maj mam ntxiv dej thaum sib tov. Qhov sib piv ntawm 10-15%% los ntawm qhov hnyav. Kev ua kom nyias 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. Kho qhov viscosity kom haum rau txoj kev siv tshwj xeeb (txhuam, dov, lossis txau).

* 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.

*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.

* Xim Sib Xws:

Nws raug pom zoo kom siv cov xim epoxy nruab nrab uas yog dej thiab cov xim acrylic/polyurethane uas yog dej los tsim cov txheej txheem "primer-intermediate-topcoat" kom ua tiav kev tiv thaiv xeb thiab kho kom zoo nkauj mus sij hawm ntev thiab txuas lub neej ntawm cov txheej txheem.

*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.

▶ 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

Qhov hnyav sib xyaw ua ke = 5: 1
