Area mala methapo - haholo-holo tafole le likhothaletso

methapo pente ke tsamaiso e tlamang, e phetha karolo e se feela bokgabane, empa hape e lelefatsa bophelo ba meralong ea. Paint mosebetsi etsoa ke consumables kang selelekela le pente. Empa kamoo ho bona hore kamoo ba lokela ho 'me e be tse lekaneng,' me keketso e setseng? Ho thata haholo-holo ho etsa sena ha a ne a rera ho palo e khōlō ea mosebetsi oa, ka mohlala, ho sebetsa le puisano e ka seteishene sa kabo. Ho hantle a bale tekanyo ea pente u lokela ho tseba sebaka mala oa phala ena. Ho ithuta mokhoa oa ho a bale e, re tla bua ka ho eketsehileng.

mefuta e sa tsoaneng ya liphaephe

Pele ho tsohle, re lokela ho hlokomela ka tshebediso ya pente tla susumetsoa feela ke le boholo ba lipeipi e, empa hape sebopeho bona le sebopeho sa lintho tse bonahalang ho tswa ho eona li le entse. Mohlala, barbotage ea lihlahisoa le boreleli 'me masenke a boholo tšoanang ho tla hlokahala hore e ngata fapaneng ya coatings.

Liphaephe ka ba le sebopeho fapaneng haholo le karolo boholo. Ho itšetlehile ka hore entsprechen tsena tse laolwang ke ho pharalla le tšebetso ea lihlahisoa phala. Mofuta o tloaelehileng haholo oa methapo cylindrical le-karolo le sefapano se chitja, hangata ka ho fetisisa sebelisoa bakeng sa kaho ea lipeipi le lipeipi khase.

A mofuta ratoang tsa tšepe tsa kaho tse phala profiled ho ba le karolo le sefapano se tse ling tse ho feta tse chitja. Ba e ka ba oval, le boholo ba lisekoere le likhutlo li 'nè. Har'a bona ba liforeimi dibopeho, mehaho e fapa-fapaneng tsa tšepe, fuluru le spans.

Masenke tube, le ho potoloha le sefapano se karolo sebelisoa bakeng sa kaho ea sekhukhu pressureless malapeng le indasteri oona tsamaisong ea likhoerekhoere, sefefo sewers.

Ho boetse ho na khoune-bopehileng tube,. Di ne a rerile hore tsamaiso ea pressurization.

litekanyo

Ho a bale tekanyo ea thepa pente ka litsela tse peli: ho sebelisa tafole e khethehileng kapa ka ho sebelisa mekhoa thutatekanyo. Le ha e le hantle, 'me haeba e mong, u lokela ho etsa litekanyo nepahetseng ea sehlahisoa.

Haeba ho na le tafole taka liphaephe lisekoere, ha rea lokela feela ho fumana ho eona boemong bo ka e tšoanang ditekanyetso tlhakore e fumaneha litekanyo, 'me pono ea enke tshebediso kapa selelekela. Manolotsoeng sebelisa mekhoa - rarahaneng ho feta, empa ha ho na tsela e ka tlase e atlehang. Ho fumana hore na mebala e sebakeng phala sebopeho itseng le karolo sefapano, le moralo tshwaneleha.

cylindrical methapo

Ho etsa dipalelo, ho ke ho hlokahala hore ho tseba bolelele ba phala le radius lona ka ntle. Bolelele e lekanngoa ka limithara tse, le mefuta e fapaneng - ho millimeters. Sebelisa moralo tse latelang:

S = 2: x π * R x, L, moo:

• S - phala sebakeng ho penta;
• π - Pi lekana le 3,14;
• R - radius;
• L - bolelele.

Ka mohlala, ha tube bolelele ba 10 limithara le bophara ba 60 limilimithara, bokaholimo sebakeng sona e ne e tla 1,88 sq. m.

The abel tšoanang e balwa, le ho colouring sebakeng liphaephe kgelelo ya leswe. Phapang feela pakeng tsa meaho tsena e le khōlō. Ka mohlala, ka liliba likhoerekhoere bophara e ka ba 70-200 cm, Maemong a joalo, ka lebaka la sebaka se phahameng sa maemo a lihlahisoa tsena -. 90 cm,.

Area colouring phala profil

Ho fumana hore na boleng ba le thahasello e kholo ke ho hlokahala hore ho tseba:

• bophahamo ba lehlakoreng le leng la phala (H);
• bophahamo ba lehlakoreng le leng (W);
• bolelele (L).

Dipalelo entsoe sebedisa moralo latelang: S = 2: x H: x L + 2: x W x, L. Ka mohlala, ha bolelele ka ba bolelele ba 10 limithara le mahlakore a - 10 le 5 cm,, sebaka ho a tlotsitsoeng ka ba 3 sq. limithara tse.

liphaephe Square tšepe taka conical

Ka liphaephe le truncated khoune mehato entsprechen latelang:

• bolelele (L);
• bophara ba lesakaneng nyenyane (R1);
• bophara ba lesakaneng kholoanyane (R2).

Ho fumana hore na mebala e sebaka sebelisoa liphaephe moralo S = 2: x π: x R1 x, L + π: x (R1: x R1 + R2: x R2). Ka mohlala, haeba moralo bolelele tla 10, m, le radii baa lekana ho 3 le 6 cm,, sebaka palo yohle e ka 2 limithara tse.

liphaephe masenke

Ka lihlahisoa tse joalo ho thata ka ho fetisisa ho ka tsela e nepahetseng a bale sebakeng holim, hobane ba ka hula hammoho bolelele. Ho phehelleng boiketlo ya manolotsoeng, litekanyetso tsohle fumanweng ka litekanyo, ke bohlale ho fana ka lengolo ka sebōpeho sa tafoleng.

Kahoo, ho hlokahala hore a seta entsprechen latelang:

• radius ea kotlobane (A);
• a bataletseng likarolo boqapi ba ka bolelele le bophara (B, D);
• mohato boholo corrugations (C);
• angle boreleli karolo (E);
• bophahamo la karolo e masenke (F);
• Product atamela mola (G).

Ka mohlala itseng, nahana kamoo dipalelo li phethahatsoa. Mohlala, boleng A o lekana le limilimithara 3. Ho bona hore boholo ba karolo e lekaneng ea ka moralo o sa 2: x π x, A e sebediswa Kahoo, 18,84 limilimithara. boleng D lokela ho imenne habeli, e ke e ho lekana le 20 limilimithara. E Thehiloe ho ya data tse ka holimo, e mong ka hore na bolelele ba corrugations le ka mokgwa otlolotse - 38,84 limilimithara.

Ho tlosa sekama, khompyuta boleng E. palo ena e tla ho lekana le ka makhetlo a mabeli le bophara ba, i.e. 12 limilimithara.

Nahana hore bolelele ba sehlahiswa e 10 m. Ho bala palo ea lemenong, bolelele arotsoe ke mohato 866 le ho fumana lintho tseo. Ka mor'a moo, beha bolelele ba tube masenke ka boemo ba motho ba sarolloa. Le bophara ba, mohlala, 52 limilimithara, e sebaka kakaretso ea kaho 54,92 sq. m.

Kgetho ya pente

Liphaephe sebediswa bakeng sa ho penta mefuta e fapaneng ya pente:

• Acrylic enamel, e leng joale ka ho hlophisoa ha solvents manyolo, ho fana ka matla 'me tsoarellang sephatsimisi fihlela qetellong.
• Alkyd enamel hlahiswa sale in e mengata e fapaneng le leholo la mebala e. inks joalo ba boetse ba tšoauoa ka durability, theha lera ka tšeptjoang ha khoa le fela.
• Metsi-dispersive pente. Melemo ea o hlophisitsoeng joalo kenyeletsa bokhoni bakeng omisa ka potlako 'me ba sieo ha malodor. Go tlhoka mesola - ho hanyetsa thusang mafutsana ho abrasion le metsi. Pele o sebedisa inks tsa qhalakana metsi-thehiloeng oa phala ea ho a tlotsitsoeng Priming moemeli.
• Oli pente. Bakeng sa liphaephe ho penta ka seoelo sebelisa. Fumaneha ka e nyenyane ea 'mala telele. Pele penta tšepe bokaholimo, ho akarelletsa le liphaephe, hlokahala tshebediso ya selelekela le, e leng e ka fana ka tlamo e matla ka pente e. Colouring sebopeho motheong oa oli e sebelisoa ho selelekela omisitsoeng le dikarolo bonyane ba babeli.

Ha a khetha mofuta oa pente ho mala phala ke ke ho hlokahala, pele ho tsohle, ho nahana ka morero le ho sebetsa maemo a bona, joalokaha lintlha tse kang mocheso, mongobo, kotsi ea tšenyo e phetha molao, joalo-joalo, e tla itšetleha ka hore na durability ya pente, le nako e liphaephe tšebeletso bona.
