Pobzeb nplaum 40 feeb qhib lub sijhawm sim

Ua ib qho kev sim los ntsuas lub sij hawm qhib ntawm pobzeb nplaum yuav ntsuas qhov ntev npaum li cas cov nplaum tseem ua haujlwm tau thiab nplaum tom qab thov. Nov yog cov txheej txheem dav dav rau kev ua 40-feeb qhib lub sijhawm sim:

Cov ntaub ntawv xav tau:

1. Pobzeb nplaum (xaiv rau kev sim)
2. Vuas los yog substrate rau daim ntawv thov
3. Timer lossis stopwatch
4. trowel los yog notched trowel
5. Dej (rau cov nplaum nplaum, yog tias tsim nyog)
6. Cov dej huv thiab daim txhuam cev (rau tu)

Txheej txheem:

1. Kev npaj:
   • Xaiv cov pobzeb nplaum los kuaj. Xyuas kom tseeb tias nws yog sib xyaw kom zoo thiab npaj raws li cov neeg tsim khoom cov lus qhia.
   • Npaj cov substrate los yog cov vuas rau daim ntawv thov los ntawm kev ua kom lawv huv si, qhuav, thiab tsis muaj plua plav lossis khib nyiab.
2. Daim ntawv thov:
   • Siv ib lub trowel los yog trowel siv ib txheej txheej ntawm cov pobzeb nplaum rau lub substrate los yog rov qab ntawm cov pobzeb.
   • Siv cov nplaum sib npaug, sib kis nws nyob rau hauv ib qho tuab tuab thoob plaws qhov chaw. Siv cov npoo ntawm cov trowel los tsim cov ridges lossis grooves hauv cov nplaum, uas pab txhim kho adhesion.
   • Pib lub timer lossis stopwatch sai li sai tau thaum siv cov nplaum nplaum.
3. Kev ntsuas lub sijhawm ua haujlwm:
   • Pib muab cov vuas rau hauv cov nplaum tam sim tom qab thov.
   • Saib xyuas lub sijhawm ua haujlwm ntawm cov nplaum los ntawm kev tshawb xyuas nws qhov sib xws thiab tackiness.
   • Txhua 5-10 feeb, maj mam kov cov nplaum nplaum nrog ib lub hnab looj tes los yog cov cuab yeej los ntsuas nws cov tackiness thiab workability.
   • Txuas ntxiv xyuas cov nplaum kom txog thaum nws mus txog qhov kawg ntawm 40-feeb qhib lub sijhawm.
4. Ua tiav:
   • Thaum kawg ntawm 40-feeb qhib lub sijhawm, ntsuas qhov xwm txheej ntawm cov nplaum thiab nws qhov tsim nyog rau kev tso cov pobzeb.
   • Yog hais tias cov nplaum tau qhuav dhau los yog tacky kom ua tau zoo ntawm cov vuas, tshem tawm cov nplaum qhuav los ntawm cov substrate siv daim txhuam cev ntub dej los yog daim ntaub.
   • Tshem tawm cov nplaum uas tau dhau lub sijhawm qhib thiab npaj cov khoom tshiab yog tias tsim nyog.
   • Yog tias cov nplaum tseem ua haujlwm tau thiab nplaum tom qab 40 feeb, ua haujlwm nrog cov pobzeb tso raws li cov chaw tsim khoom cov lus qhia.
5. Cov ntaub ntawv:
   • Sau cov kev soj ntsuam thoob plaws hauv qhov kev sim, suav nrog cov tsos thiab qhov sib xws ntawm cov nplaum ntawm ntau lub sijhawm.
   • Nco ntsoov cov kev hloov pauv ntawm cov nplaum nplaum, kev ua haujlwm tau zoo, lossis cov yam ntxwv ziab lub sijhawm.

Los ntawm kev ua raws li cov txheej txheem no, koj tuaj yeem ntsuas lub sijhawm qhib ntawm cov nplais nplaum thiab txiav txim siab nws qhov tsim nyog rau cov ntawv thov tshwj xeeb. Kev hloov kho tuaj yeem ua rau tus txheej txheem raws li qhov xav tau raws li cov nplaum tshwj xeeb raug sim thiab cov xwm txheej ntawm qhov chaw sim.
