Cov ntaub ntawv siv hauv cov thawv ntim khoom thiab qhov sib txawv ntawm lawv

Cov khoom siv feem ntau rau lub thawv hluav taws xob muaj xws li hlau, yas, thiab cov khoom sib xyaw. Lawv qhov sib txawv tseem ceeb yog nyob rau hauv kev tiv thaiv corrosion, mechanical zog, rwb thaiv tsev, nqi, thiab kev siv ib puag ncig.

1. Txias-rolled steel ntawv

Qhov zoo: Tus nqi qis, siab load-cov kabmob muaj peev xwm, yooj yim rau vuam thiab daim ntawv.

Disadvantages: Prone to rusting thaum lub txheej puas lawm; tsis haum rau qhov chaw ntub dej lossis corrosive ib puag ncig.

Cov xwm txheej tsim nyog: Qhuav hauv tsev ib puag ncig, xws li cov chaw nyob zoo ib yam, cov tsev ua haujlwm, thiab cov khw muag khoom.

Kev kho saum npoo: yuav tsum yog xeb- pov thawj los ntawm electroplating lossis txau. Grey faib lub thawv siv sab hauv tsev feem ntau yog hom no.

 

2. Stainless hlau

Qhov zoo: Zoo heev corrosion thiab oxidation tsis kam, siab structural zog, aesthetically pleasing thiab yooj yim los ntxuav.

Qhov tsis zoo: Tus nqi siab, 3-5 npaug ntawm cov hlau zoo tib yam, hnyav, yuav tsum tau txiav txim siab hauv av, khawb qhov saum npoo yog qhov nyuaj rau kho.

Cov xwm txheej tsim nyog: Cov tshuaj lom neeg, cov ntug dej hiav txwv, khoom noj, thiab chaw muag tshuaj uas muaj zog corrosion, high humidity, los yog nruj me ntsis kev tu cev.

 

3. Aluminium alloy

Qhov zoo: Lub teeb yuag, ib txwm muaj corrosion-resistant, zoo tshav kub dissipation.

Disadvantages: Tsawg zog thiab hardness, yooj yim puas nto, thiab tus nqi siab dua li qub hlau.

Cov ntawv thov tsim nyog: Nyhav- qhov chaw nkag siab lossis ib puag ncig uas xav tau kom muaj cua sov zoo, xws li aerospace, siab - qhov kub thiab txias, thiab qee qhov tawg - cov ntaub ntawv pov thawj.

 

4. Engineering yas

Qhov zoo: Cov rwb thaiv tsev zoo heev, lub teeb yuag, qee cov ntaub ntawv, xws li PC, yog pob tshab rau kev soj ntsuam yooj yim.

Disadvantages: Tsis tshua muaj neeg kho tshuab lub zog, nquag laus thiab deformation, kuj tsis zoo siab -kub kuj thiab nplaim retardancy, tsis zoo cua sov dissipation.

Tsim nyog Scenarios: Nyob sab hauv tsev ib puag ncig, ib puag ncig uas yuav tsum muaj kev rwb thaiv tsev siab, xws li cov thawv me me hauv tsev, cov thawv tsis muaj zog tam sim no, cov thawv ntim pob tshab.

 

5. Fiberglass

Qhov zoo: Lub teeb yuag thiab siab zog, zoo heev rwb thaiv tsev thiab corrosion kuj, huab cua tsis kam, hloov tau raws li kev xav tau.

Disadvantages: tus nqi siab dua, kuj tsis muaj zog hnav tsis kam, thermal conductivity tsis zoo.

Cov xwm txheej tsim nyog: Cov cheeb tsam sab nraum zoov hnyav, xws li lub thawv ntsuas sab nraum zoov, lub thawv tswj lub teeb pom kev, cov thawv xa khoom ntawm ntug hiav txwv lossis cov nroj tsuag tshuaj.

 

 

Txias-Rolled Steel Phaj vs. Stainless Steel
Txias- dov steel phaj cia siab rau cov txheej txheem rau kev tiv thaiv xeb; Thaum cov txheej txheej puas lawm, xeb yuav tshwm sim.

Stainless hlau nws tus kheej tsis xeb, thiab txheej puas tsuaj tsis cuam tshuam rau nws cov kev ua tau zoo. Yog li ntawd, stainless hlau yuav tsum tau xaiv rau sab nraum zoov, ntub, thiab corrosive ib puag ncig.

 

Engineering Plastics vs. Fiberglass
Ob leeg yog insulating. Txawm li cas los xij, engineering plastics muaj lub zog tsawg thiab tsis tiv taus ntev - lub hnub raug tshav thiab kev laus; fiberglass muaj lub zog siab thiab huab cua tsis zoo, ua rau nws tsim nyog rau qhov hnyav sab nraum zoov lossis chaw ua haujlwm.
