Kom ua kua yas nrog koj txhais tes, koj yuav tau npaj cov hauv qab no:

• Thawv ntawm iav lossis hlau;
• Acetone;
• Polystyrene ua npuas ncauj.

Hauv qhov no, cov acetone siv npaum li cas yog nyob ntawm cov khoom ntim ntawm cov khoom tiav.

Yog hais tias koj xav ua kua yas nrog koj tus kheej tes, daim ntawv qhia rau nws cov kev npaj yuav ua raws li cov dissolving ntawm npaus hauv acetone. Rau qhov no, siv polystyrene ua npuas ncauj. Nws yog ib ntim rau ntau tsev neeg thiab khoom siv hluav taws xob.

Yuav ua li cas ua kua yas los ntawm koj tus kheej

Kauj ruam yog kauj ruam daim ntawv qhia ua cov hais tias cov ntaub ntawv uas yog raws li nram no:

1. Qhib lub khob nrog acetone thiab ncuav cov kua rau hauv lub khob ntim kom nws theem ntawm qhov hauv qab yog kwv yees li 1 cm.
2. Polystyrene npaus yuav tsum tawg mus rau hauv ntau daim me me, txhua yam uas yuav muab tau yooj yim tso rau hauv lub thickness ntawm qhov hnyav.
3. Kua yas ua tau los ntawm tes, poob txhua daim mus rau hauv ib lub khob thiab tos nws txoj kev xaus.
4. Styrofoam yuav tsum muab ntxiv rau lub khob kom txog thaum nws nres tas lawm. Tom qab ntawd koj yuav tsum tau tos 5-10 feeb rau cov pob txha tsis siv rau evaporate.
5. Tom qab qhov no, ib qho dej khov loj yog tsim hauv qab ntawm lub khob, uas siv tau los tsim ntau yam khoom.

Paub yuav ua li cas ua kua yas, nco ntsoov tias tag nrho hardening ntawm qhov loj kav 20-30 xuab moos. Txawm li ntawd los, lub tuam txhab raug tshem tawm tsis tuaj yeem raug tshem tawm ntawm pwm nyob rau lub sijhawm ntawd.

Nws yuav tsum tau thov nrog lub me me roj hmab qhov roj hmab nplaum. Nyob rau tib lub sijhawm, qhov taw yuav tsum yog tus. Kua yas yuav tsum tau ncav lub nplaim dej kom zoo. Yog hais tias nws tau sau nrog qhov qhwv, nws yog qhov zoo dua rau siv txhuam nrog cov tawv pawg. Lawv yuav tsum "thawb" qhov sib tov rau qhov khoob. Tom qab nplua nplaum yas, nws pom zoo kom siv ib txheej ntxiv ntawm cov khoom.

Cov khoom piav tau ntev tau raug muag hauv daim ntawv npaj ua tiav. Nws yuav tsum tsuas rhaub tau hauv cov dej los yog hauv cov khoom siv tshwj xeeb. Tsis tas li ntawd, lub tsev plaub hau tshuab feem ntau siv rau qhov no.

Raws li txoj cai, cov kua yas ua tau rau hauv cov pob ntseg nruj. Nws cov lus thiab tej yam kev mob ntawm kev cia yog nruj. Qhov kub nyob hauv chav nyob qhov twg nws nyob yuav tsum tsis poob rau hauv 15 degrees. Txwv tsis pub, lub cuab tam yuav poob kev ua tau zoo:

• Viscosity;
• Elasticity;
• Hardness tom qab hardening;
• Tswv yim;
• Durability.

Tus nqi ntawm cov yas yas yog heev. Tias yog vim li cas nws yog qhov zoo tshaj los ua koj tus kheej.

Cwj pwm

Acetone yog kua ntau heev, uas muaj qhov tsis zoo Ntawm tib neeg lub cev. Yog li no, cov kua yas tsuas tuaj yeem tsim nrog nrog kev pab los ntawm nruj kev ua raws li cov lus hauv qab no:

1. Ua ntej ua hauj lwm nrog acetone, koj yuav tsum ua tib zoo soj ntsuam cov lus qhia rau nws siv. Nws tau sau rau ntawm daim ntawv lo ntawm lub khob.
2. Cov iav tshwj xeeb thaiv hauv qab yuav tsum hnav. Lawv yuav tiv thaiv koj ob lub qhov muag yog tias mob thiab kua ua kua. Ua hauj lwm tsis muaj lawv tuaj yeem ua rau raug mob loj qhov muag.
3. Acetone yog lom, yog li siv nws tsuas yog nyob rau hauv ib qho chaw zoo. Nws yog ib qho tsim nyog yuav tau siv kev tiv thaiv kab mob ntsws.
4. Qhov no yog ib yam khoom kub hnyiab. Yog li, kua yas nrog lawv cov tes tsis deb ntawm cov chaw qhib hluav taws. Thiab thaum ua haujlwm, kev haus luam yeeb tsis raug cai txwv.
5. Tshem cov acetone raug txwv tsis pub mus rau hauv cov kav dej.
6. Tom kawg ntawm tus txheej txheem, as Well as tom qab lub hnab yas rau hauv pwm, koj yuav tsum ntxuav koj ob txhais tes.

Daim ntaub ntawv ntawm cov kua yas hauv kho kom zoo nkauj

Rau qhov xaus, txoj kev kho mob yuav siv ntev. Tom qab nws daim ntawv thov, ib zaj dab neeg zoo nkauj tshwm rau saum npoo los kho. Nws muaj cov dej tsis haum thiab tsis kam mus ultraviolet raug. Kev tiv thaiv los ntawm cov khoom siv zoo li zaj duab xis tsis yog ntshai ntawm kev cuam tshuam ntawm txhoj puab heev. Tus sab nrauv muaj qhov ntxiag ci thiab nws cov yeeb yam rau ntau xyoo.

Cov kua ua kua hauv qhov rais ua haujlwm

Feem ntau cov khoos phom tshiab rau hauv qhov chaw sib koom tes muaj khoob khoob. Yuav kom tsis txhob muaj qhov tshwm sim zoo li no, tag nrho cov ntsiab lus ntawm lub qhov rais ntawm lub qhov rais, uas sib txuas nrog ib leeg, raug kho nrog cov khoom uas tau piav qhia. Nws tom qab ziab tsim nyob rau ntawm ib qho zuam zaj dab neeg. Daim ntawv thov kua yas rau ntawm cov qhov rais nrog koj txhais tes tau tom qab tsim cov khoom raws li cov txheej txheem saum toj no.

Tus neeg saib xyuas kev xeb xeb

Cov kua ua kua yog tshwm sim los ntawm cov qib high degree ntawm adhesion rau hlau ntom raug kho. Cov cuab yeej ntawm cov khoom no tau siv nyob rau hauv qhov kev kho anticorrosion steel. Cov kua ua kua yog siv rau qhov tsis muaj priming. Nws dries hauv ob peb teev. Tom qab ntawd, ib zaj duab xis yog tsim nyob rau saum npoo, uas tiv thaiv cov khoom los ntawm cov tsos ntawm xeb.
