Umgangatho wepeyinti kunye ne-varnish yokugquma kuxhomekeke kulungiselelo lomphezulu womthi. Ngaphambi konyango lokugqibela, ukufuma kufuneka kuhlolwe, umphezulu kufuneka ucocwe kakuhle, ukungalingani kufuneka kuzaliswe kwaye kususwe uthuli.
Ukufuma kwenkuni phambi kokugqiba
Ukhuni oluza kupeyintwa kufuneka lomiswe lube kumanzi 10–12%, ngelixa iinkuni eziza kuqatywa ivanishi kunye nokupholishwa kufuneka zomiswe ukuze 8%.
Kumphezulu womthi onokufuma okuphezulu, ukusuka ku-20 ukuya ku-30%, ipeyinti kunye neengubo zokuvanisa azimkelwa kakuhle kwaye ziguga ngokukhawuleza. Isizathu kukuba xa ukoma, imilinganiselo yomthi iyancipha kwi-radial kunye ne-tangential directions, ngelixa inyuka xa imanzi.
Ukuba imilinganiselo yokhuni iguquka kwimida emikhulu, i-elasticity yepeyinti ye-scram kunye ne-varnish iba yinto enganeleyo. Xa iinkuni zomile, i-coating ishwabene kwaye i-peel, kwaye xa imanzi, iyahlukana nemithi okanye ikrazula kwiindawo ezininzi.
Iiklasi zokucwangcisa, ukucola kunye nococeko
Umphezulu ulungiswa ngokohlobo lokugqiba:
Kwizikrini ezixineneyo, tsala itafile ngokuthe tye ukuze ubone yonke imiqolo.
| Uqhubekeko lokugqibela | Ukucwangcisa | Ukugaya | Iklasi yococeko |
|---|---|---|---|
| Iityali ezivulekileyo | Ubude beWaveleng 4–2,5 mm | Sanding paper 120 | VI okanye VII |
| Ukupeyinta | Ubude bobude ukuya kuthi ga 2 mm | Iphepha lokusantiya 120–140 | VIII okanye IX |
| Ukumenyezwa ngepolishi ye-shellac | Ubude bamaza ukuya kuthi ga1 mm, emva koko intsimbi - umatshini wokuhamba ngebhayisikile | Iphepha lesanti140-170 | X |
Umthi ogqunywe ngezinto zokupeyinta ezenza isikram se-opaque zicutshungulwa kuqala kwiiplani, kwaye emva koko zifakwe isanti kwiklasi echaziweyo yokucoceka.
Ukuzalisa amaqhuma
Ngaphambi kokupeyinta, zonke izitenxo zomhlaba, kubandakanywa amaqhina, imikrwelo kunye nee-nicks, kufuneka zilungiswe kwaye zizaliswe.
Imingxuma evela kwiindawo ezilahlayo kufuneka zifakwe iplagi ukwenzela ukuba isalathiso semicu yeplagi ihambelane nolwalathiso lwemicu yento.
Ukufuma kunye nesanti yokugqibela
Ngaphambi kokupholisa kunye ne-varnishing, umphezulu womthi kufuneka ufunjwe kancinci ngamanzi. Emva koko2-3emva kokumisa, umphezulu ulungiswa nge-sandpaper170-200ibekwe phezu kwemethi ye-softwood yemilinganiselo100×100 mm.
Ukugaya kwenziwa ecaleni kweenkozo zokhuni kunye neentshukumo ezilinganayo. Emva kwesanti, imveliso okanye into kufuneka ixutywe ngeqhekeza elithambileyo kunye nothuli kufuneka lucocwe ngebrashi.
Ukuqala kunye nokuzaliswa
Ngaphambi kokufaka iipeyinti kunye neevanishi ezenza iingubo ze-opaque, ukhuni luxutywe ngeoli okanye enye i-primer. Ukuba kuyimfuneko, i-puttying yendawo okanye i-puttying yomhlaba wonke iyenziwa.
Grund kufuneka:
- vala imingxuma;
- ibopha isambatho somthi;
- phucula ukunamathela kokugquma.
Umbala we-primer kunye nesihluzi kufuneka uhambelane nombala imveliso eza kupeyintwa ngawo.
Xa ivanishi kunye nokupholisha, ukuhlanjululwa kwenziwa ngeeprayimari ezikhethekileyo ezicacileyo okanye iivanishi ezixutywe kunye neepolisi eziza kusetyenziselwa ukugqiba. Umzekelo, kunyango olukumgangatho ophezulu kunye nepolisi ye-shellac, umphezulu womthi uqatywe nge-10% shellac polish.
