Pele ho tsohle, holim'a boemo bo phahameng ba ho nepahalatube ea koporoe tla etsa lera le thata la tšireletso, ho sa tsotellehe hore na ke mafura, lik’habohaedreite, libaktheria le likokoana-hloko, maro a kotsi, oksijene kapa mahlaseli a ultraviolet, e ke ke ea feta ho eona, leha e le hore e ka senyeha ho silafatsa boleng ba metsi, ’me likokoana-hloko li ke ke tsa feta ho eona.Ha e khone ho lula holim'a liphaephe tsa koporo ho li nolofatsa.Li-tubes tsa koporo tse nepahetseng haholo li thata ho feta li-tubes tsa polasetiki, li tenyetseha ho feta litšepe tse tloaelehileng, li sebetsa habonolo, 'me li na le khanyetso e itseng ea serame.Thepa e phahameng ea koporo e phahameng e na le khatello e phahameng ea khatello, e tiisang hore e ka boloka ts'ebetso e babatsehang esita le tlas'a khatello e phahameng ntle le ho senyeha kapa ho phunyeha.
Mokhoa oa ho tjheseletsa ka koporo ka kakaretso ke ho tjheseletsa ka kgase, terata ya koporo, borax.Ela hloko boholo ba lelakabe ha u cheselletsa.Sebelisa tjheseletso ea khase pele ho chesa peipi ea koporo e khubelu.Ka nako ena, ela hloko lelakabe le leputsoa bohareng ha u lokisa lelakabe, 'me u le fetole nako e telele, ho seng joalo mocheso o tla ba o phahameng haeba o le khutšoanyane.Eketsa borax, 'me u kenye terata ea tšepe ea koporo ka mor'a hore borax e qhibilihe.
Mehato ea Brass Soldering
1. Nakong ea ts'ebetso ea welding, kamehla boloka lelakabe le koahela manonyeletso ho thibela moea ho kena;
2. Phallo e tla omisoa, 'me mongobo o tla fetoha mouoane ho 100 ° C,' me phallo e tla ba e tšoeu ea lebese.
3. Flux e tla phophoma ka 316°C.
4. Flux e fetoha peista ho 427°C
5. Phallo e fetoha mokelikeli ho 593 ° C, e leng haufi le mocheso oa brazing.
6. Solder e nang le 35% -40% silevera e qhibiliha ho 604 ° C 'me e phalla ho 618 ° C.
7. Hlokomela hore lihlahisoa tse peli tse lokelang ho chesetsoa li tlameha ho futhumatsoa ka toche ea welding.
8. U ka bona hore na mocheso o loketse ka 'mala oa lelakabe.Ha mocheso o fihla mocheso oa brazing, lelakabe le tla bonahala le le tala, 'me lelakabe le letala le tla bontša hore mocheso o loketse ha o fihla mocheso oa tjheseletsa oa silevera.
9. Ho cheselletsa phala ea koporo le phala ea tšepe ho e mong, phala ea koporo e tlameha ho futhumatsoa pele (hobane phala ea koporo e chesa ka potlako 'me e hloka mocheso o mongata).
10. Nakong ea ts'ebetso ea brazing, lebone la welding ha lea lokela ho emisa ka nako e le 'ngoe ka linako tsohle, empa le ka sisinyeha ka sebopeho sa setšoantšo sa robeli.
11. Ho kgothaletswa hore o sebelise toche e kholo, e le hore mocheso o moholo o ka fumanoa ka lelakabe le bonolo ntle le khatello e feteletseng kapa "ho butsoa", ka ho khetheha ka khanya e nyenyane ka har'a lelakabe le ka hare la conical.
