Cheeb Tsam xim hlab - tshwj xeeb tshaj yog rooj thiab cov tswv yim

Xim hlab yog ib tug yuav tsum sai, uas plays ib tug luag hauj lwm tsis tsuas zoo nkauj, tab sis kuj prolongs lub neej ntawm lub raj dej. Xim ua hauj lwm ua los ntawm xws li consumables li primer thiab xim. Tab sis yuav ua li cas los mus txiav txim yuav ua li cas npaum li cas lawv yuav tsum tau thiab muaj txaus, thiab cov seem tseem tshuav? Nws yog tshwj xeeb tshaj yog yooj yim ua li no thaum npaj ib tug loj npaum li cas ntawm kev ua hauj lwm, piv txwv li, kev sib txuas lus ua nyob rau hauv lub tis rau chaw nres tsheb. Yuav kom zoo xam tus nqi ntawm cov xim koj yuav tsum paub cov xim cheeb tsam ntawm cov yeeb nkab. Yuav kom kawm tau li cas los xam nws, peb mam li tham ntxiv.

ntawm ntau yam kav

Ua ntej ntawm tag nrho cov, nws yuav tsum tau muab sau tseg rau cov xim muaj hlau noj yuav tau pawg tsis tau tsuas yog los ntawm qhov luaj li cas ntawm cov kav dej, tab sis kuj lawv zoo thiab qauv ntawm cov ntaub ntawv los ntawm uas lawv tau. Piv txwv li, txheej ntawm du thiab corrugated khoom ntawm tib yam loj yuav tau sib txawv ntawm cov coatings.

Kav yuav muaj sib txawv heev zoo thiab seem me me. Nyob ntawm seb cov tsis, txiav txim los ntawm lub Scope thiab cov lag luam ntawm cov yeeb nkab khoom. Feem ntau daim ntawv ntawm cylindrical menyuam nrog ncig tus ntoo khaub lig-section, feem ntau siv rau kev tsim kho ntawm pipelines thiab roj pipelines.

Ib tug nrov hom hlau ntawm qhov kev siv yog cov Profiled yeeb nkab muaj ib tug ntoo khaub lig seem lwm tshaj ncig. Lawv yuav ua tau dawb, square thiab lub. Ntawm lawv yog cov ntas lug, ntau yam hlau lug, plag tsev thiab spans.

Corrugated raj nrog ib puag ncig tus ntoo khaub lig seem yog siv rau cov kev siv ntawm underground pressureless domestic thiab muaj dej system, cua daj cua dub sewers.

Muaj kuj yog lub khob hliav qab-zoo li tus raj. Lawv yog npaj rau pressurization systems.

ntsuam

Yuav kom xam tus nqi ntawm cov xim ntaub ntawv nyob rau hauv ob txoj kev: siv ib tug tshwj xeeb cov lus los yog los ntawm kev siv geometric qauv. Thiab nyob rau hauv qhov tseeb, thiab nyob rau hauv lwm cov ntaub ntawv, koj yuav tsum ua kom yog kev ntsuas ntawm cov khoom.

Yog hais tias muaj yog ib lub rooj coloring square kav, peb yuav tsum tsuas nrhiav tau nyob rau nws ib txoj hauj lwm nrog rau cov tib seem tsis raws li tau los ntawm kev ntsuas, thiab saib number case noj los yog phau pib qhia. Muab xam los siv cov qauv - ntau nyuab, tab sis tsis muaj tsawg txoj kev. Yuav kom txiav txim cov xim cheeb tsam yeeb nkab kev zoo thiab tus ntoo khaub lig seem, rau cov mis.

cylindrical menyuam

Kom suav, nws yog tsim nyog los paub qhov ntev ntawm cov yeeb nkab thiab nws cov txheej voos kheej-kheej. Qhov ntev yog ntsuas nyob rau hauv meters, thiab ntau yam - nyob rau hauv millimeters. Siv cov nram no mis:

S = 2 x π * R x L, qhov twg:

• S - yeeb nkab cheeb tsam yuav tsum tau pleev xim rau;
• π - pi sib npaug zos rau 3.14;
• R - voos kheej-kheej;
• L - ntev.

Piv txwv li, thaum lub raj ntev ntawm 10 m thiab ib lub cheeb ntawm 60 mm, nws saum npoo cheeb tsam yuav 1,88 sq. m.

Cov tib kab zauv xam, thiab coloring cheeb tsam phwj kav. Qhov txawv tsuas nruab nrab ntawm cov Siv cov loj loj. Piv txwv li, nyob rau hauv kav dej phwj dej txoj kab uas hla tej zaum yuav 70-200 cm Nyob rau hauv xws li mob, lub hauv paus ntawm ib tug txheej txheem qhov siab ntawm cov khoom no -. 90 cm.

Cheeb Tsam coloring yeeb nkab profile

Yuav kom txiav txim seb qhov nqi ntawm kev txaus siab yog tsim nyog los paub:

• lub qhov siab ntawm ib sab ntawm cov yeeb nkab (H);
• lub qhov siab ntawm qhov tod tes (W);
• ntev (L).

Suav yog ua siv cov nram qab mis: S = 2 x H x L + 2 x W x L. Piv txwv li, thaum ntev nyob rau hauv lub qhov siab ntawm 10 m thiab sab - 10 thiab 5 cm, lub cheeb tsam yuav tsum tau loj yuav tsum muaj 3 sq. meters.

Square steel kav coloring conical

Nyob rau hauv cov kav dej nrog truncated lub khob hliav qab ntsuas nram qab no tsis:

• ntev (L);
• txoj kab uas hla ntawm lub voj voog me (R1);
• txoj kab uas hla ntawm lub loj lub vajvoog (R2).

Yuav kom txiav txim seb qhov xim qhov chaw thov cov kav dej mis S = 2 x π x R1 x L + π x (R1 x R1 + R2 x R2). Piv txwv li, yog hais tias tus tsim ntev yuav yog 10 m, thiab cov radii yog muaj sib npaug mus rau 3 thiab 6 cm, tag nrho cov cheeb tsam yog hais txog 2 meters.

corrugated kav

Nyob rau hauv tej khoom hauv lub feem ntau nyuaj los yog xam cov deg hauv cheeb tsam, vim hais tias lawv muaj peev xwm yuav rub raws qhov ntev. Rau yooj yim ntawm kev xam, tag nrho cov qhov tseem ceeb tau nyob rau hauv cov kev ntsuam, nws yog advisable rau qhov teeb meem nyob rau hauv kev sau ntawv nyob rau hauv daim ntawv ntawm ib lub rooj.

Yog li, qhov yuav tsum tau muab cov nram qab no tsis:

• voos kheej-kheej ntawm curvature (A);
• tiaj projection qhov chaw nyob rau hauv qhov ntev thiab txoj kab uas hla (B, D);
• kauj ruam loj corrugations (C);
• lub du feem (E);
• lub qhov siab ntawm lub corrugated feem (F);
• Khoom nqus ib kab (G).

Nyob rau hauv ib tug piv txwv, xav txog yuav ua li cas cov lus teb yog nqa tawm. Piv txwv li, cov nqi A yog sib npaug zos rau 3 hli. Yuav kom txiav txim seb qhov loj ntawm lub sib npaug ib feem ntawm cov mis 2 x π x A yog siv li, ib tug 18,84 hli. D nqi yuav tsum tau ob npaug, cia nws ua ncaj rau 20 mm. Raws li cov saum toj no cov ntaub ntawv, ib tug yuav txiav txim qhov ntev ntawm lub corrugations nyob rau hauv lub stretched daim ntawv - 38,84 hli.

Tshem qaij, xam tus nqi E. Qhov no xam yuav sib npaug zos rau ob zaug txoj kab uas hla, i.e. 12 hli.

Xav hais tias hais tias qhov ntev ntawm cov khoom yog 10 m. Yuav kom suav tus xov tooj ntawm folds, qhov ntev muab faib los ntawm cov kauj ruam 866 thiab muab tau cov khoom. Tom ntej no, txiav txim qhov ntev ntawm lub corrugated raj nyob rau hauv ib tug stretched mob. Nrog ib lub cheeb ntawm, e.g., 52 hli, tag nrho cov cheeb tsam ntawm qhov kev siv 54,92 sq. m.

Xaiv cov xim tsev

Kav siv rau nrag ntau hom xim tsev:

• Acrylic enamel, uas yog tam sim no nyob rau hauv nyob tus yeees ntawm cov organic solvents, muab ib tug muaj zog thiab check gloss finish.
• Alkyd txha hniav laus hais rau cov muag khoom nyob rau hauv ib tug loj ntau ntawm cov xim. Tej inks kuj yus muaj los ntawm durability, tsim ib txhim khu kev qha txheej tsis tawg thiab ploj.
• Dej-dispersive xim. Qhov zoo ntawm cov xws compositions xws li cov muaj peev xwm rau ceev ceev kom qhuav thiab tsis tuaj kawm ntawv ntawm malodor. Tsis zoo - cov neeg pluag kuj mus puas thiab dej. Ua ntej siv inks dej-raws li dispersion ntawm cov yeeb nkab yuav tsum tau coated priming neeg sawv cev.
• Roj xim. Rau painting kav tsis tshua muaj siv. Muaj nyob rau hauv ib tug me me xim ntau yam. Ua ntej nrag hniav hlau, nrog rau cov kav dej, yuav tsum tau daim ntawv thov ntawm ib tug primer, uas yuav muab tau ib tug muaj zog daim ntawv cog lus nrog rau cov xim muaj hlau. Coloring muaj pes tsawg leeg rau ntawm lub hauv paus ntawm cov roj yog thov mus rau lub qhuav primer tsawg kawg yog ob khaubncaws sab nraud povtseg.

Thaum xaiv cov hom xim rau xim tus yeeb nkab yog tsim nyog, ua ntej ntawm tag nrho cov, ua kom pom tseeb nyob rau hauv lawv lub hom phiaj thiab kev khiav hauj lwm tej yam kev mob, raws li yam tseem ceeb xws li kub, humidity, kev pheej hmoo ntawm cov neeg kho tshuab kev puas tsuaj, thiab lwm yam, yuav yog nyob ntawm seb yuav ua li cas lub durability ntawm cov xim muaj hlau, thiab lub sij hawm kev pab cuam kav lawv tus kheej.
