> Kev xaiv cov khoom siv huv huv

Ib: Wood qeb:
Anticorrosive khoom ntoo: ntuj, ib puag ncig tus phooj ywg thiab nyab xeeb (cov ntoo yog nyob rau hauv nws cov xim qub, me ntsis ntsuab).Qhov tseeb, ntxiv rau cov yam ntxwv los tiv thaiv corrosion, cov ntoo tiv thaiv corrosion kuj muaj cov yam ntxwv zoo permeability thiab muaj zog tiv thaiv kom tsis txhob poob.Nyob rau tib lub sijhawm, nws tuaj yeem cuam tshuam qhov kev hloov pauv ntawm cov dej noo ntawm cov ntoo kho thiab txo qhov degree ntawm cov ntoo tawg.Cov khoom siv hauv tsev los tiv thaiv corrosion feem ntau suav nrog Ob yam khoom: Lavxias Pinus sylvestris thiab Nordic Scots Pine.Cov ntoo preservative ua los ntawm Lavxias teb sab ntoo thuv yog feem ntau yog cov preservative ntoo kev kho mob ntawm imported cav nyob rau hauv Tuam Tshoj, thiab lawv feem ntau yog kho nrog CCA cov neeg sawv cev.Cov ntoo preservative ua los ntawm Nordic liab ntoo thuv yog preservatively kho txawv teb chaws, thiab cov ntoo preservative tuaj rau lub teb chaws rau kev muag khoom ncaj qha yog kho nrog ACQ cov neeg ua hauj lwm thiab feem ntau hu ua "Finnish ntoo".Tib neeg tau siv los hu cov ntoo khaws cia ua Finnish ntoo.Qhov tseeb, qhov no tsis yog lawm.Nws yog ib qho yooj yim rau cov neeg uas tsis to taub preservative ntoo kom to taub yuam kev.
Ob: Stainless hlau
xeb thiab acid-resistant steel yog abbreviated li stainless hlau.Qhov saum npoo ntawm stainless hlau phaj yog du thiab muaj siab plasticity, toughness thiab mechanical zog.Nws yog resistant rau corrosion los ntawm acids, alkaline gases, kev daws teeb meem thiab lwm yam xov xwm.Nws yog cov hlau alloy uas tsis yooj yim rau xeb, tab sis nws tsis yog xeb-dawb kiag li.Stainless hlau phaj yog cov hlau phaj uas tiv taus cov xov xwm tsis muaj zog xws li cua, chav dej thiab dej, thaum cov kua qaub-resistant steel yog hais txog cov hlau phaj uas tiv taus cov kua qaub, alkali, ntsev thiab lwm yam tshuaj corrosive media.Nws yog tsim los ntawm stainless hlau thiab acid-resistant steel.Cov hlau uas tuaj yeem tiv taus atmospheric corrosion yog hu ua stainless hlau, thiab cov hlau uas tuaj yeem tiv taus tshuaj lom neeg corrosion yog hu ua acid-resistant steel.Feem ntau hais lus, hlau nrog cov ntsiab lus ntawm Wcr ntau dua 12% muaj cov yam ntxwv ntawm cov hlau tsis muaj steel.Raws li lub microstructure tom qab kev kho cua sov, stainless hlau yuav muab faib ua tsib pawg: ferritic stainless hlau, martensitic stainless hlau, austenitic stainless hlau, Austenitic-ferritic stainless hlau thiab precipitated carbide stainless hlau.
Vim tias cov hlau tsis muaj corrosion kuj zoo heev, formability, compatibility, thiab toughness nyob rau hauv ib tug dav kub ntau yam, nws tau dav siv nyob rau hauv hnyav kev lag luam, lub teeb kev lag luam, kev lag luam niaj hnub, kev lag luam kho kom zoo nkauj thiab lwm yam lag luam..
Peb: Kub-dip galvanized ntawv qeb:
Galvanized steel ntawv yog los tiv thaiv corrosion ntawm daim ntawv hlau thiab ua kom nws lub neej ua haujlwm ntev.Qhov saum npoo ntawm cov ntawv hlau yog coated nrog ib txheej ntawm hlau zinc.Hom galvanized steel ntawv no yog hu ua galvanized ntawv.
Raws li kev tsim khoom thiab kev ua haujlwm, nws tuaj yeem muab faib ua pawg hauv qab no:
① Kub-dip galvanized steel ntawv.Lub nyias steel phaj yog immersed nyob rau hauv lub molten zinc da dej, thiaj li hais tias ib tug nyias steel phaj nrog ib tug txheej ntawm zinc yog adhered rau saum npoo.Tam sim no, cov txheej txheem galvanizing tsis tu ncua yog siv rau kev tsim khoom, uas yog, cov ntawv dov steel yog txuas ntxiv rau hauv lub galvanized da dej nrog molten zinc los ua cov ntawv hlau galvanized;
② Alloyed galvanized steel ntawv.Hom steel phaj no kuj yog tsim los ntawm kub dipping txoj kev, tab sis tom qab nws tawm ntawm lub tank, nws yog rhuab mus txog 500 ℃ tam sim ntawd los ua ib tug alloy zaj duab xis ntawm zinc thiab hlau.Hom ntawv galvanized no muaj cov xim zoo adhesion thiab weldability;
③ Electro-galvanized steel ntawv.Cov ntawv hlau galvanized ua los ntawm txoj kev electroplating muaj kev ua haujlwm zoo.Txawm li cas los xij, cov txheej txheej yog thinner, thiab corrosion kuj tsis zoo li cov ntawv kub-dip galvanized;
④ Ib sab thiab ob sab sib txawv galvanized steel ntawv.Ib sab galvanized steel ntawv yog ib yam khoom uas yog galvanized ntawm ib sab nkaus xwb.Nyob rau hauv vuam, painting, anti-xeb kev kho mob, ua, thiab lwm yam., nws muaj zoo adaptability dua ob-sided galvanized ntawv.Txhawm rau kom kov yeej qhov tsis txaus ntawm cov zinc tsis muaj coated ntawm ib sab, muaj lwm hom galvanized ntawv coated nrog ib txheej nyias ntawm zinc ntawm lwm sab, uas yog, ob sab sib txawv galvanized ntawv;
⑤ Alloy thiab composite galvanized steel ntawv.Nws yog ua los ntawm zinc thiab lwm yam hlau xws li txhuas, txhuas, zinc, thiab lwm yam los ua alloys los yog txawm composite plated steel daim hlau.Hom steel phaj no tsis tsuas yog muaj kev ua haujlwm zoo los tiv thaiv xeb, tab sis kuj muaj cov txheej txheem zoo;
Ntxiv rau tsib hom saum toj no, muaj cov xim galvanized steel ntawv, luam ntawv coated galvanized steel ntawv, thiab PVC laminated galvanized steel los xij.Tab sis tam sim no feem ntau siv yog tseem kub-dip galvanized ntawv.

Plaub: Yas
Vim tias nws yog ua los ntawm cov yas, nws yog hu ua lub thoob khib nyiab yas.Cov muaj pes tsawg leeg: high-density polyethylene HDPE los yog polypropylene PP polypropylene ob lub yas tshiab tshiab.
Nta:
(1) Acid kuj, alkali tsis kam, corrosion kuj thiab muaj zog huab cua tsis kam;
(2) Lub kaum sab xis tsim ntawm qhov chaw xa khoom muaj kev nyab xeeb thiab tsis muaj txiaj ntsig;
(3) Qhov saum npoo yog du thiab huv, txo cov khib nyiab pov tseg thiab yooj yim los ntxuav;
(4) Nws tuaj yeem ua zes rau ib leeg, uas yooj yim rau kev thauj mus los thiab txuag chaw thiab nqi;
(5) Nws tuaj yeem siv tau ib txwm nyob hauv qhov kub ntawm -30 ℃ ~ 65 ℃;
(6) Muaj ntau yam xim xaiv los ntawm, uas tuaj yeem sib phim raws li kev xav tau ntawm kev faib tawm;
(7) Nws yog dav siv nyob rau hauv ntau qhov chaw, thiab tseem tuaj yeem siv rau kev sau cov khib nyiab, xws li cov khoom, lub Hoobkas, kev huv, thiab lwm yam.

Qhov zoo:
Cov thoob khib nyiab yas yog cov txheej txheem yooj yim thiab yog ua los ntawm cov khoom siv txuag hluav taws xob.Hauv kev siv, nws tsis tsuas yog txo cov nqi ntau, tab sis nws kuj muaj qhov ua tau zoo tshaj plaws rau kev txhim kho kev pab cuam lub neej.Cov thoob khib nyiab yas kuj muaj cov zaub zoo rau kev tu ntau dua.Peb ib txwm muab pov tseg rau hauv lub thoob khib nyiab.Rau ntau tus menyuam tam sim no, nws tseem yuav muaj qhov tseem ceeb ntawm kev kawm zoo dua, ua rau nws siv rau hauv kev siv.Qhia txog kev siv cov khoom siv sib txawv.Kev yooj yim ntawm kev ntxuav kuj yog qhov zoo ntawm cov thoob khib nyiab yas, uas qhia tau hais tias ntau tus neeg siv-phooj ywg tsim lub tswv yim ntawm cov thoob khib nyiab hauv kev siv.
