4. Impact Resistance: Fiberglass nthuav tawm cov kev cuam tshuam zoo heev, muaj peev xwm tiv taus lub cev muaj zog.
Lub teeb yuag: Thaum ua tau raws li qhov yuav tsum tau muaj zog, qhov hnyav ntawm cov qauv fiberglass tau txo qis, yog li txo qis kev teeb tsa thiab kev thauj mus los.
Durability Performance
Qhov zoo tshaj plaws corrosion tsis kam - tag nrho xeb-dawb, haum rau cov av noo siab, tshuaj tsuag ntsev, thiab tshuaj tiv thaiv corrosion; nruab nrab hnav tsis kam - yog tias thauj cov khoom ntse (xws li hlau lossis pob zeb crushed), qhov saum npoo yog khawb tau yooj yim, thiab ntev ntev - hnav yuav ua rau cov fibers raug; kuj tsis muaj zog tiv thaiv - nws yuav tawg nyob rau hauv tej yam hnyav, thiab nyuaj rau kho tom qab tawg; tsis zoo li steel, nws tsis tuaj yeem welded, thiab feem ntau yuav tsum tau kho tag nrho lossis hloov. Lub neej kev pab cuam yog kwv yees li 3-5 xyoos, nyob ntawm seb hom khoom thauj.
Kev txhais ntawm Aluminium Alloys
Aluminium alloys yog alloys tsim los ntawm kev ntxiv lwm yam hlau ntsiab rau txhuas, nrog txhuas yog cov khoom tam sim no nyob rau hauv ntau tshaj plaws. Aluminium alloys yog ib qho ntawm cov khoom siv dav tshaj plaws ntawm cov khoom siv tsis yog -ferrous hlau structural cov ntaub ntawv nyob rau hauv kev lag luam, dav siv nyob rau hauv aerospace, automotive, machinery manufacturing, shipbuilding, thiab tshuaj industries. Cov muaj pes tsawg leeg thiab cov khoom ntawm aluminium alloys muab lawv cov kev ua tau zoo hauv ntau daim ntawv thov engineering.
Kev tsim khoom
1. Melting
Melting yog thawj kauj ruam hauv kev tsim cov aluminium alloys, feem ntau suav nrog cov cua sov aluminium thiab nws cov ntsiab lus alloying rau lub xeev molten los tsim cov ingots. Melting furnaces feem ntau siv cov roj los yog cov cua sov ua kom sov, thiab cov alloy muaj pes tsawg leeg yuav tsum tau tswj xyuas thaum lub sij hawm melting txheej txheem los xyuas kom meej tias kev ua tau zoo ntawm aluminium alloy ua tau raws li qhov yuav tsum tau ua.
2. Casting
Casting yog txheej txheem ntawm pouring molten aluminium rau hauv pwm thiab cia nws txias thiab solidify los ua ib tug casting. Feem ntau casting txoj kev rau txhuas alloys muaj xws li xuab zeb casting thiab tuag casting. Thaum lub sij hawm casting txheej txheem, lub fluidity thiab txias npaum li cas ntawm cov molten aluminium muaj ib tug tseem ceeb cuam tshuam rau qhov zoo ntawm lub casting.
3. Kev ua cov yas
Cov txheej txheem yas yuav tsum ua cov khoom siv los yog cov castings rau hauv cov duab uas xav tau thiab loj los ntawm txoj kev xws li dov, extrusion, thiab kos duab. Cov txheej txheem ua cov yas feem ntau suav nrog extrusion thiab dov, uas yog siv dav hauv kev tsim cov txhuas profile, txhuas ntawv, thiab txhuas ntawv ci.
4. Kev kho cua sov
Kev kho cua sov yog siv los txhim kho cov khoom siv ntawm aluminium alloys los ntawm cov txheej txheem cua sov thiab cua txias. Cov txheej txheem kev kho cua sov feem ntau suav nrog kev daws kev kho mob thiab kev laus kev kho mob, uas tuaj yeem ua rau muaj zog thiab tawv tawv ntawm aluminium alloys.

Kev kho deg yog siv los txhim kho corrosion kuj thiab zoo nkauj ntawm aluminium alloys. Cov txheej txheem kho saum npoo muaj xws li anodizing, txau, thiab electroplating. Cov kev kho mob no tuaj yeem ua kom ntev kev pab cuam lub neej ntawm aluminium alloys thiab txhim kho lawv cov tsos.
Cov yam ntxwv thiab qhov zoo
1. Lub teeb yuag: Qhov ntom ntawm aluminium alloys yog kwv yees li ib -thib peb ntawm cov hlau, ua rau lawv tsim nyog rau cov ntawv thov kom txo qhov hnyav.
2. High Strength: Lub zog ntawm qee cov aluminium alloys nyob ze lossis tshaj qhov siab - zoo steel, ua rau lawv haum rau cov qauv uas yuav tsum tau tiv taus siab loads.
3. Corrosion Resistance: Lub ntuj tsim oxide zaj duab xis nyob rau saum npoo ntawm txhuas alloys zoo tiv thaiv corrosion, ua rau lawv haum rau siv nyob rau hauv hnyav ib puag ncig. 4. Kev ua tau zoo heev: Aluminium alloy yog yooj yim rau txheej txheem thiab tsim, haum rau ntau yam kev tsim xws li extrusion, casting, thiab vuam.
Durability Performance
Corrosion kuj yog superior rau txias- dov steel, thib ob tsuas yog fiberglass; hnav tsis kam yog nruab nrab, thiab qhov saum npoo yog nquag khawb, tab sis nws yuav tsis xeb thiab kis tau zoo li hlau; kev cuam tshuam tsis zoo yog qhov nruab nrab, thiab cov dents yuav tshwm sim thaum muaj kev cuam tshuam hnyav, xav tau cov cuab yeej tshaj lij los kho; load- bearing muaj peev xwm nyob nruab nrab ntawm txias- dov steel thiab fiberglass, haum rau nruab nrab thiab lub teeb load scenarios. Lub neej kev pabcuam yog kwv yees li 4-6 xyoo, thiab ua tsaug rau nws cov yam ntxwv sib zog, kev siv roj tsheb tuaj yeem txo los ntawm 8% -12%.
II. Overseas Adaptation Scenarios
1. Txias-rolled steel: Haum rau hnyav- daim ntawv thov xws li thauj cov khoom siv hauv tsev thiab cov zaub mov hauv Central Asia thiab hauv tebchaws Africa; Qhov zoo tshaj plaws rau cov neeg yuav khoom uas tsis tshua nkag siab txog tus nqi tu thiab saib xyuas qhov muaj peev xwm ua ntej thiab kev cuam tshuam. Piv txwv li, lub tsheb txias -rolled steel cargo van yuav los ntawm Nigerian cov khoom siv hauv tsev yog nqa 2-3 tons ntawm cov khoom txhua hnub thiab, nrog rau kev pleev xim rau txhua xyoo, qhia tias tsis muaj qhov cuam tshuam loj tom qab 6 xyoo ntawm kev siv.
2. Fiberglass: Haum rau kev thauj cov txiv hmab txiv ntoo thiab zaub, thiab cov khoom siv dej hauv cov ntug dej hiav txwv sab hnub tuaj Asia thiab thaum lub caij los nag hauv teb chaws Africa, los yog nyob rau hauv cov xwm txheej uas xav tau kev sib cuag nrog cov khoom acidic lossis alkaline; Qhov zoo tshaj plaws rau cov neeg yuav khoom uas xav tau kev tiv thaiv corrosion siab heev thiab cov neeg thauj khoom tsis tu ncua (xws li cov thawv ntawv thiab cov khoom ntim khoom). Piv txwv li, lub fiberglass cargo van siv los ntawm ib tug Nyab Laj cov khoom noj khoom haus distributor rau thauj cov nqaij nruab deg nyob rau hauv ntug hiav txwv dej qhia tsis muaj corrosion tom qab 4 xyoo ntawm kev siv, tsuas yog me me nto khawb.
3. Aluminium alloy: Haum rau cov cheeb tsam uas xav tau siab ntawm kev siv roj thiab kev tiv thaiv ib puag ncig, xws li Europe thiab Middle East, nrog rau kev faib hauv nroog thiab cov khoom me me thoob ntiaj teb; zoo tagnrho rau cov neeg yuav khoom uas nrhiav kev ua haujlwm tau zoo, feem ntau ua haujlwm lub teeb rau nruab nrab loads, thiab xav txo cov nqi roj. Piv txwv li, aluminium alloy cargo van yuav los ntawm lub khw loj hauv UAE thauj khoom tsawg dua 1 tuj ib hnub thiab, tom qab 5 xyoos ntawm kev siv nyob rau hauv siab - kub thiab siab - av noo ib puag ncig, qhia tias tsis muaj corrosion thiab ua kom pom qhov zoo ntawm roj efficiency.
III. Tswv yim rau Extending Lifespan ntawm Cargo Containers
Txawm hais tias xaiv cov khoom siv, kev siv thiab kev saib xyuas kom zoo tuaj yeem txhim kho durability thiab txo cov nqi hloov pauv:
1. Txias- dov steel cargo ntim: Siv tshuaj tiv thaiv{{2} xeb xim 1-2 zaug hauv ib xyoos. Thaum thauj cov khoom ntse, nteg cov roj hmab mats rau ntawm phab ntsa sab hauv ntawm lub thawv kom tsis txhob muaj kev sib txhuam ncaj qha; Tam sim ntawd ntxuav cov dej thiab cov av hauv lub thawv tom qab los nag los tiv thaiv corrosion.
2. Fiberglass cargo ntim: Tsis txhob thauj cov khoom ntse lossis hnyav. Yog tias tsim nyog, nruab cov khoom tiv thaiv; niaj hnub tshuaj xyuas lub thawv ntim thiab kho cov khawb nrog cov resin tam sim kom tiv thaiv cov dej nag los ntawm kev nkag mus rau hauv thiab ua rau muaj fiber ntau.
3. Aluminium alloy cargo thawv: Tsis txhob muaj kev cuam tshuam hnyav thiab kev sib tsoo. Thaum thauj khoom, faib cov khoom sib npaug kom txo qis kev ntxhov siab ntau dhau ntawm cov chaw tshwj xeeb; tsis tu ncua ntxuav lub thawv nrog dej kom tsis txhob muaj cov roj stains los ntawm accumulating thiab cuam tshuam rau cov khoom nto.
