Heev feem ntau, ob qho tib si hauv lub neej txhua hnub thiab hauv kev tsim khoom, txhais tau tias yuav tsum tau gluing cov ntaub ntawv. Cov kua nplaum Epoxy yog ib qho uas feem ntau siv hom nplaum thiab muaj ntau yam zoo. Tab sis zoo li ib yam khoom, kua nplaum epoxy muaj nws tus yam ntxwv uas cuam tshuam rau qhov txiaj ntsig kawg.

Peculiarities

Ua ntej pib ua cov nplaum ntawm qhov chaw, nws yog qhov tsim nyog kom nkag siab qhov sib xyaw ntawm cov kua nplaum no, cov hauv paus ntsiab lus ntawm nws qhov kev nqis tes ua thiab daim ntawv thov.

Cov kua nplaum epoxy muaj dab tsi? Cov lus teb rau lo lus nug no nyob hauv lub npe ntawm cov kua nplaum nws tus kheej. Nws yog raws li epoxy cob, uas yog ib hom khoom siv hluavtaws thiab muaj cov khoom siv thoob ntiaj teb.

Cov tshuaj yuav tsum muaj qhov ntsuas kub kom kho tau. Rau epoxy resin, nws txawv ntawm -10 txog +200 degrees. Kev xaiv qhov kub thiab txias nyob ntawm seb muaj pes tsawg hom. Nyob ntawm qhov kub uas qhov tshuaj tiv thaiv yuav tshwm sim, epoxy resins tau muab faib ua hom txias thiab kub kho. Hom txias yog siv rau cov ntaub ntawv uas tsis raug rau kev kho cua sov, thiab hom kub xav tau rau cov khoom siv uas tuaj yeem tiv tsis tau tsuas yog kub siab, tab sis kuj tseem raug rau cov tshuaj muaj zog.

Kev kho khaub thuas txias feem ntau yog siv los ua cov khoom sib txuas hauv tsev ., thiab tseem siv hauv kev lag luam me. Rau cov tsev cog khoom loj, kho kub yog qhov haum tshaj plaws. Lub dav hlau, tshuab khoos phis tawj, hluav taws xob tsim hluav taws xob, xov tooj cua siv hluav taws xob, kev tsim nkoj thiab lwm yam khoom siv hauv tsev siv epoxy resins hauv kev tsim cov nplaum.

Ntxiv rau epoxy resin, cov kua nplaum muaj cov tawv tawv; tsis muaj nws, txheej txheem polymerization tsis yooj yim sua. Nws yog cov tawv tawv uas, tau rov ua dua nrog epoxy resin, pab nws tawv thiab tsis yaj.

Ntawm kev muag, cov tshuaj thiab cov tawv tawv nyob hauv cov fwj sib txawv; rau gluing, cov khoom no yuav tsum tau diluted hauv qhov yuav tsum tau ua. Ob lub Cheebtsam yog cov polymers nrog lub cev hnyav me me, thaum lawv cuam tshuam, cov molecules yooj yim ua ke, ua rau muaj cov polymer loj molecule (thaum ua kom tiav).

Txhawm rau ua kom cov txheej txheem polymerization nrawm dua, koj tuaj yeem nce qhov kub thiab nce qhov hnyav, thiab ua kom qeeb cov tshuaj tiv thaiv, ua raws nraim qhov sib txawv, txo qhov kub thiab txo qhov hnyav.

Kev sib xyaw ua ke ntawm epoxy nplaum yog tus yam ntxwv ntawm qib siab ntawm cov nplaum , lawv tuaj yeem ua kua nplaum yuav luag txhua cov ntaub ntawv: hlau, roj hmab, iav, yas, ntoo, qhov tseem ceeb tshaj plaws yog sib xyaw cov kua thiab cov tawv tawv hauv qhov sib npaug. Tom qab ua tiav tawv tawv, kho saum npoo nrog cov khoom sib xyaw no tuaj yeem ua rau muaj kev ua haujlwm: sib tsoo, sawing, drilling thiab lwm yam haujlwm tuaj yeem ua tiav yam tsis hloov pauv cov khoom.

Yuav ua li cas yug?

Dilution ntawm kua nplaum yuav tsum tau saib xyuas tshaj plaws, yog li nws yog qhov zoo tshaj plaws los npaj txhua yam cuab yeej tsim nyog thiab cov cuab yeej tiv thaiv ua ntej.

Cov hnab looj tes roj hmab thiab lub npog ntsej muag yuav xav tau txhawm rau tiv thaiv daim tawv nqaij thiab cov pa ua pa, vim tias ob qho tib si yog cov tshuaj lom heev. koj xav tau cov ntim rau diluting cov khoom thiab cov nplaum rau sib tov lawv. Ib qho ntxiv, chav nyob uas yuav ua haujlwm yuav tsum muaj cua nkag tau zoo.

Nyob ntawm qhov muaj pes tsawg leeg, epoxy tuaj yeem tsim cov khoom sib txawv ntawm kev nruj. Rau qhov ua kom khov khov, ib hom kev sib xyaw tau tsim, thiab rau qhov nyuaj, nws yog qhov sib txawv kiag li. Yog li ntawd, nws yog qhov yuav tsum tau yuav cov khoom siv thiab npaj cov nplaum sib xyaw, nruj me ntsis soj ntsuam qhov sib npaug uas tau qhia los ntawm cov khw.

Feem ntau, cov yas thiab cov tawv tawv tawv tuaj nrog cov lus qhia ., uas ib txwm qhia yuav ua li cas sib xyaw cov khoom kom raug, thaum soj ntsuam qhov sib npaug ntawm kev sib tov. Raws li txoj cai, txhawm rau npaj cov nplaum, nws yuav tsum tau dilute cov khoom sib xyaw 10: 1 - rau 10 feem ntawm cov tshuaj muaj 1 feem ntawm cov tawv tawv.

Tab sis cov neeg tsim khoom niaj hnub no tsim cov sib txawv sib txawv uas tsis tas yuav tsum tau diluted hauv txoj kev no, qee zaum txhawm rau txhawm rau npaj cov nplaum sib xyaw, nws yuav tsum tau sib xyaw cov tshuaj thiab cov tawv tawv hauv qhov sib txawv.

Qhov kev faib ua feem nyob ntawm tus neeg tsim khoom tshwj xeeb. Hauv ib kis, qhov sib piv tuaj yeem yog 10: 4, hauv lwm qhov - 10: 6, thiab qhov thib peb, kom ua tiav qhov xav tau sib xws, koj yuav tsum tau dilute 4 ntu ntawm cov tawv tawv hauv 6 ntu ntawm cov tshuaj. Qhov kev faib ua feem sib cais tsis yog tsuas yog nyob ntawm cov chaw tsim khoom tshwj xeeb, tab sis kuj nyob rau hnub tso tawm ntawm cov tshuaj thiab tawv tawv, kev khaws cia, qhov kub ib puag ncig, thiab, ntawm chav kawm, ntawm qhov zoo ntawm ob yam khoom.

Yav dhau los, txhawm rau kom tsis txhob yuam kev nrog tus nqi ntawm cov khoom ntxiv, cov tuam txhab tsim cov fwj nrog cov cim, tab sis niaj hnub no tsis muaj kev sib cais ntawm lub fwj, yog li sib xyaw cov khoom xyaw tuaj yeem ua tiav siv cov txheej txheem sib txawv.

Txhawm rau kos tus nqi me me, koj tuaj yeem siv tus cwj mem qub los ntawm hauv qab tus cwj mem. Ua ntej siv, nws tau ntxuav kom huv thiab cov cim tau siv rau saum npoo ntawm qhov tsis tu ncua.

Koj tuaj yeem ntsuas tus nqi ntawm cov khoom siv siv lub cuab yeej yooj yim dua - rab koob txhaj tshuaj . Muaj twb tau cim rau nws, koj tsis tas yuav kos lawv tus kheej, thiab lawv tau siv ntau dua qhov raug ntau dua li cov uas tau ua nrog koj txhais tes ntawm tus pas nrig. Txhawm rau ncuav lub zog rau hauv rab koob, koj tsuas yog yuav tsum tau tshem rab koob thiab tso nws los ntawm lub piston, thiab cov kua nplaum yuav tsum tau muab tso rau hauv nws hauv qhov sib txawv me ntsis, vim tias nws yuav tsis ua haujlwm los kos nws los ntawm lub raj dej - nws muaj qhov sib xws uas yog khov heev. Hauv lub raj syringe, nws yog qhov tsim nyog kom tshem tawm rab koob, tshem lub plunger thiab ntsaws lub qhov taub, thiab tsuas yog tom qab ntawd ncuav cov tshuaj los ntawm sab saum toj.

Txhawm rau kom sib xyaw epoxy kom raug, koj thawj zaug yuav tsum tau npaj txhua qhov kev sib xyaw rau dilution . Kev ntsuas tus nqi ntawm cov pob tshab pob tshab ntxiv rau hauv lub khob thiab sib xyaw kom huv. Qee zaum cov tshuaj epoxy tau sib xyaw hnyav heev, yog li ntawd, txhawm rau ua kom yooj yim rau cov txheej txheem no, nws tuaj yeem ua kom sov hauv chav da dej, 50-60 degrees yog txaus. Tab sis nws tsim nyog nco ntsoov tias qhov nce ntawm qhov kub tsis tsuas yog ua kom yooj yim rau kev sib xyaw, tab sis tseem ua kom nrawm cov txheej txheem polymerization - koj tsuas yog xav kom nce qhov kub ntawm qhov sib xyaw los ntawm 10 ° C, thiab cov tshuaj tiv thaiv yuav nrawm dua 2-3 zaug.

Tom qab kev npaj, cov khoom yuav tsum tau muab sib xyaw thiab sib tov hauv lub khob huv, tab sis qhov no yuav tsum tsis txhob ua kom nruj heev, txwv tsis pub cov npuas tuaj yeem zam tau. Lawv nyob hauv cov kua nplaum tuaj yeem ua rau pom qhov pom ntawm cov khoom nchuav yog tias muaj pes tsawg leeg tau siv los ua cov ntim.

Rau qhov yooj yim gluing ntawm qhov chaw, tus naj npawb ntawm cov npuas tsis muaj teeb meem tiag tiag. Yog tias cov xim zas tau ntxiv rau qhov muaj pes tsawg leeg, tom qab ntawd nws yog qhov zoo dua los siv lawv qhuav, txij li cov dej noo, txawm tias tsawg heev, cuam tshuam tsis zoo rau cov nplaum.

Cov tshuaj tau npaj ua ntej thawj feeb muaj cov kua sib xws, tab sis tom qab 10-15 feeb nws pib tuab sai, thiab tom qab 30 feeb nws tawv. Txhawm rau txuas ntxiv lub sijhawm ua haujlwm nrog cov tshuaj muaj pes tsawg leeg, koj tuaj yeem siv cov cuab yeej xws li acetone - nws yuav ua rau lub sijhawm ua kua nplaum ntau dua li 1 teev. Txhawm rau ua qhov no, koj yuav tsum yaj tsuas yog 1 feem ntawm cov khoom no hauv kev sib xyaw nrog 10: 1: 1 piv.

Yuav siv li cas?

Nws tsis txaus los npaj cov tshuaj kom raug, koj kuj yuav tsum tau siv nws zoo. Cov kua nplaum tuaj yeem siv ob qho tib si ua qhov txuas txuas thiab ua rau nchuav rau hauv cov pwm npaj.

Txog kev ua kom ruaj khov ntawm cov ntaub ntawv, muaj cov kev cai npaj dav dav:

• kev kho lub tshuab ntawm cov khoom siv los ntawm kev sib kis;
• degreasing npaj cov gluing cov ntsiab lus los ntawm cov roj av; rau qhov no, cov kuab tshuaj, acetone lossis xab npum yog qhov tsim nyog;
• qhov chaw uas muaj qhov ci tau ua tiav siv cov ntawv xuab zeb lossis lub log sib tsoo.

Rau kev yooj yim gluing, kev sib xyaw ua ke tau thov rau ib qho ntawm ob sab, tom qab uas ob lub ntsej muag raug nias nruj nreem rau ib leeg. Koj tuaj yeem siv txoj hlua muaj zog, vise, clamps lossis hnyav li clamps. Cov kua nplaum uas seem tau muab tshem tawm nrog daim ntaub qhuav lossis ntaub so ntswg. Cov khoom siv glued yuav tsum nyob hauv txoj haujlwm ruaj khov rau tsawg kawg 24 teev thaum thawj txheej txheem polymerization tab tom ua tiav, tom qab ntawd cov pab cuam txuas txuas raug tshem tawm, thiab cov khoom glued tau sab laug kom qhuav tag rau 7 hnub.

Thaum siv cov ntawv sau tshwj xeeb, lawv tau npaj sib txawv . Hauv qab thiab sab raug kho nrog cov rog. Tom qab lubrication, cov lus sib xyaw ua tiav tau nchuav rau hauv pwm thiab khaws cia hauv nws kom txog thaum kho tiav. Txhawm rau nce qhov nrawm ntawm polymerization, tom qab 3 teev ntawm kev tuav cov pwm ntawm chav sov, nws raug xa mus rau qhov cub kom sov. Yog tias pwm tsis kub, cov txheej txheem ua kom tiav tuaj yeem siv sijhawm txog 7 hnub.

Cov Tswv Yim

Thaum npaj cov khoom sib xyaw, ntxiv rau thaum thov nws rau saum npoo lossis ntim cov pwm nrog cov kua nplaum no, muaj cov lus qhia thoob ntiaj teb los pab ua kom zoo dua qub.

Thaum npaj cov khoom sib xyaw, nws yog qhov zoo dua los siv cov tais diav thiab cov cuab yeej pabcuam uas tsis tsim nyog rau kev siv ntxiv. Nws yuav luag tsis yooj yim los ntxuav lawv ntawm qhov muaj pes tsawg leeg, yog li txhua lub ntim thiab cov cuab yeej siv rau kev sib xyaw yuav raug muab pov tseg.

Kev nchuav rau hauv cov pwm yuav tsum tau ua tiav hauv theem, tshwj xeeb tshaj yog tias nws tau npaj los ua cov txheej tuab ntau dua 2 hli. Tom qab thawj txheej tau kho lawm, cov pob tom ntej yog nchuav tsuas yog tom qab txheej tau kho, tab sis nrog cov nplaum nplaum.

Rau cov ntim loj, nws yog qhov zoo dua los yuav cov ntawv tshwj xeeb .tsis raug rau overheating. Thaum sib tov ntau ntau ntawm cov kua nplaum zoo tib yam, muaj kev pheej hmoo ntawm cov muaj pes tsawg leeg ua rau hluav taws kub. Yog li ntawd, rau koj tus kheej kev nyab xeeb, koj yuav tsum suav ua ntej qhov yuav tsum tau ntim ntawm cov khoom sib xyaw thiab yuav cov kua nplaum, suav tshwj xeeb rau qhov ntim no.
