Cov kua nplaum yog ib qho ntawm cov khoom xav tau tshaj plaws hauv lub neej txhua hnub thiab kev tsim kho. Scope ntawm nws daim ntawv thov yog dav heev, cov kev xaiv rau kev siv yog tsis kawg. Clay plasticine yog ib qho kev hloov kho ntawm cov tshuaj ib txwm siv uas tso cai rau kev sib khi thiab sib khi yuav luag txhua yam khoom. Cov cuab yeej siv tau yooj yim thiab siv tau yooj yim.
YEpoxy kua nplaum
Cov khoom no yog cov khoom siv hluavtaws. Nws muaj epoxy resin thiab ntau yam hardeners thiab plasticizers. Nws cov khoom yog xws li tias thaum sib cuag nrog huab cua, nws hloov los ntawm cov kua los yog mos mos rau hauv ib qho khoom thiab ruaj khov. Cov khoom no yog siv nyob rau hauv kev tsim kho, thiab nyob rau hauv lub neej txhua hnub, thiab nyob rau hauv dav hlau tsim, thiab nyob rau hauv shipbuilding, thiab nyob rau hauv zus tau tej cov tsheb. Rau tib neeg, nws tsuas yog hloov tsis tau.
Epoxy nplaum feem ntau yog cais los ntawm kev muaj pes tsawg leeg.
Qee zaum:
- Ib feem - npaj txhij siv, tso cai rau koj siv nws rau saum npoo yam tsis muaj cov kauj ruam ntxiv. Zoo li cov kua los yog ib lub strip ntawm plasticine.
- Ob lub ntsiab lus - muaj cov resin thiab hardener. Muab nyob rau hauv ob lub raj mis sib cais. Ua ntej siv, cov kua nplaum no yuav tsum tau muab sib xyaw ntawm nws tus kheej mus rau qhov xav tau sib xws.
Glue plasticine - txias vuam
Qhov no yog ib hom kev sib txuas ua ke. welding txias yog lub npe ntawm ib txoj kev uas tso cai rau koj los txuas cov khoom, nrog rau cov hlau, tsis tas siv cov khoom siv vuam thiab kub kub. Feem ntau, lo lus no hais txog kev sib txuas ntawm qhov chaw nrog epoxy plasticine kua nplaum, uas muab lub zog tuav.
Cold welding tsis haum rau txhua yam khoom. Yog li, epoxy kua nplaum yuav tsis tiv nrog qhov chaw ua los ntawm Teflon, polypropylene, polyethylene thiab silicone. Txawm li cas los xij, qhov kev sib txuas txias txias tau dhau los ua qhov dav heev, vim tias txoj kev no muaj ntau qhov zoo. Qhov tseem ceeb tshaj plaws ntawm lawv yog tsis kam mus rau qhov kub thiab txias, av noo thiab dryness, elasticity, nrog rau lub zog thiab durability. Tag nrho cov kev ua tau zoo no tau ua rau cov cuab yeej siv tsis tau.
cov lus qhia Epoxy
Kev siv epoxy, zoo li lwm yam, qhov tseem ceeb tshaj plaws yog npaj cov chaw. Lawv yuav tsum tau ntxuav kom huv si li sai tau, nyiam dua nrog cov ntawv xuab zeb lossis acetone, uas yuav ua rau cov dej tsis huv.
Tom qab ntawd nrog cov hnab looj tes ntub dej (qhov no yog qhov tseem ceeb kom tsis txhob muaj kev daws teeb meemnws) koj yuav tsum sib tov cov khoom xyaw hauv qhov kev faib ua feem yog tias siv ob lub nplaum nplaum, thiab tsuas yog siv rau saum npoo. Kev kho ntawm qhov chaw gluing yog xav tau nyob rau ob peb teev tom ntej no. Txawm li cas los xij, qhov ntsuas no yog nyob ntawm qhov kev kho ntawm cov nplaum nplaum - qee qhov sib txuas nrawm nrawm rau ob peb feeb.
Adhesive plasticine kuj muaj muag, haum rau kho thav duab, duab, daim ntawv qhia hnub thiab lwm yam khoom siv phab ntsa. Xws li cov khoom siv los hloov cov nplaum nplaum, tso cai rau koj kom ceev cov khoom siv lub teeb yam tsis muaj qhov drilling qhov ntawm cov phab ntsa thiab nrog kev pab los ntawm cov rau tes. Cov kua nplaum no tiag tiag zoo li plasticine, tab sis tsis tawm stains, siv tau yooj yim, muaj adhesion ntau dua.
ua tus kheej
Rau cov neeg feem coob hauv lub neej niaj hnub, siv cov khoom lag luam zoo tib yam cov kua nplaum yuav zoo, tab sis rau lub hom phiaj tshwj xeeb, koj tuaj yeem siv cov khoom xyaw ua los ntawm koj tus kheej.
Feem ntau, ua epoxy kua nplaum hauv tsev tsis nyuaj. Cov lus qhia ntxaws txog yuav ua li cas ua kua nplaum-plasticine feem ntau nthuav tawm ntawm cov pob khoom nrog cov tawv tawv thiab epoxy. Cov no yog cov khoom tseem ceeb, muag ib tus zuj zus hauv cov khw muag khoom txhim kho tsev feem ntau.
Qhov feem ntau feem ntau yog ib feem hardener rau kaum feem epoxy. Nyob ntawm cov proportions no, cov khoom ntawm cov khoom tshwm sim kuj yuav hloov.
Thiab thiaj li yuav tau nplaum plasticine ntawm qee yam xim, uas tuaj yeem ua tauyuav siv tau nyob rau hauv lub neej txhua hnub raws li ib tug zoo nkauj caij, zaub mov xim ntawm cov xim yuav tsum tau muab ntxiv rau qhov sib tov. Tag nrho cov khoom yuav tsum tau muab sib xyaw kom huv si hauv lub khob ntim, tiv thaiv koj txhais tes nrog hnab looj tes. Yav tom ntej, nws yuav tsum raug cais tawm ntawm huab cua lossis siv tam sim tom qab ua noj.
Zoo kawg
Kev npaj cov kua nplaum yas yog ib txoj haujlwm yooj yim uas tsis tas yuav muaj kev txawj tshwj xeeb. Nyob ntawm qhov sib npaug ntawm cov khoom, nws tuaj yeem tau txais ob qho tib si mos mos thiab yas sib xyaw, thiab cov khoom siv tawv heev tsim nyog rau gluing nto. Nws yog ib qho tseem ceeb heev uas yuav tau ua raws li cov lus qhia uas tuaj nrog lub ntim ntawm cov khoom thiab ua raws li cov lus pom zoo ntawm cov kws tshaj lij. Txawm hais tias cov kua nplaum yas tsis muaj tshuaj lom, nws nyuaj siab heev los siv nws ua khoom ua si rau menyuam yaus.
