2024 Tus sau: Howard Calhoun | [email protected]. Kawg hloov kho: 2023-12-17 10:28

Tej zaum cov ntaub ntawv tiv thaiv dav tshaj plaws yog nyob rau hauv qhov chaw uas siv hlau ua haujlwm. Piv txwv li, kev ua haujlwm ntawm ntau lub tshuab tau lees paub los ntawm qhov tseeb tias lawv cov khoom yog ua los ntawm cov ntaub ntawv uas muaj zog tiv taus hnav thiab corrosion.

Galvanic khoom tiv thaiv

Raws li kev hnav ntawm lub tshuab qhov chaw, piv txwv li, feem ntau qhov no tshwm sim vim qhov kev sib txhuam tsis tu ncua ntawm cov khoom tawm tsam ib leeg. Nws kuj tuaj yeem cuam tshuam los ntawm thaj chaw ua haujlwm ib puag ncig. Txhawm rau txhawm rau txhim kho qhov hnav tsis kam ntawm cov khoom zoo li no, cov khoom siv tiv thaiv yog siv. Piv txwv li, lawv tau siv dav heev los tiv thaiv lub tog raj kheej hauv lub tshuab hluav taws xob sab hauv. Txoj kev zoo tshaj plaws los khaws cov hlau saum npoo yog siv electroplating.

Siv cov txheej no los tiv thaiv pab hauv qab no:

• txo qis hnav ntawm qhov chaw;
• kho kom zoo nkauj zoo dua yog siv cov txheej tiv thaiv thiab kho kom zoo nkauj;
• Tam sim no cov khoom qub qub tau rov qab los;
• muaj zog nceclutch.

YChrome plating

Chrome tuaj yeem siv los ua cov khoom tiv thaiv. Chrome plating ntawm qhov chaw yog daim ntawv thov ntawm cov hniav thiab tiv thaiv txheej. Cov txheej txheem no tso cai rau kev nce ntxiv hauv kev hnav tsis kam, nrog rau kev kho dua tshiab ntawm cov khoom qub qub, yog tias siv cov txheej txheem chromium plating. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias cov txheej txheem no tsis yog ib txwm cuam tshuam. Kev siv cov chromium ua cov txheej tiv thaiv rau kev kho kom rov qab los ntawm qhov chaw ua tsis ncaj ncees yog tias hnav ntau dua 0.7-1 hli.

Ntxiv rau, txheej nrog cov hlau no ua rau muaj kev tiv thaiv ntawm cov hlau kom corrosion. Vim li no, cov tshuaj tiv thaiv zoo tshaj plaws rau lub tsheb yog cov uas ua los ntawm chromium. Muaj ob hom khoom uas yuav tsum tau chrome plating:

• Cov ntsiab lus uas yuav tsum tau ua kom hnav tsis kam yog tias lawv muaj kev sib txhuam siab thaum ua haujlwm.
• Tsis tas li, chromium plating tuaj yeem rov qab qhov loj ntawm ib feem uas tau qis dua thaum lub tshuab ua haujlwm.

tiv thaiv cov ntaub ntawv thermal

Hnub no, kev siv cov ntaub ntawv tiv thaiv ntawm lub tshav kub-insulating yog dav heev. Lawv txoj kev xaiv yog suav hais tias yog qhov nyuaj heev, vim tias cov tshuaj muaj ntau tus yam ntxwv. Vim li no, txhua yam khoom siv tuaj yeem siv rau hauv ib puag ncig tshwj xeeb, raws li nws cov kev txwv.

Raws li kev xaiv ntawm tus neeg tiv thaiv zoo li no,ces koj yuav tsum tau xyuam xim rau cov ntsiab lus hauv qab no:

• scope thiab lub hom phiaj ntawm cov khoom;
• nplaim taws tus nqi ntawm cov khoom;
• tus nqi ntawm kev tiv thaiv kom ya raws thiab kab mob phem;
• muaj feem cuam tshuam rau microclimatic tej yam kev mob lossis tib neeg kev noj qab haus huv;
• price.

Moistureproof properties

Ib qho ntawm cov khoom tseem ceeb ntawm cov ntaub ntawv tiv thaiv yog dej tsis kam, tshwj xeeb tshaj yog thaum nws los txog rau txheej txheej insulating. Nyob rau hauv rooj plaub no, qhov tsawg dua noo noo cov khoom absorbs, qhov zoo dua. Qhov no yog vim lub fact tias cov dej kiag li rhuav tshem qhov zoo ntawm cov ntaub ntawv insulating, raws li nws yog ib tug zoo heev conductor. Tsis tas li ntawd, nyob rau hauv cov cheeb tsam sib koom ua ke muaj kev pheej hmoo siab ntawm pwm los yog lwj nrog cov dej tsis muaj zog. Yog li ntawd, txhua qhov chaw docking yuav tsum yog lub cev qhuav dej tag.

Nws kuj yuav tsum nkag siab tias cov dej noo tsis yog kua xwb. Piv txwv li, dej vapor, kuj yog qhov txaus ntshai heev. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum tau coj mus rau hauv tus account lub siab vapor-dej impermeability ntawm hom khoom tiv thaiv no. Vim lub fact tias cov av noo nyob rau hauv txoj kev thiab sab hauv tsev feem ntau sib txawv, muaj ib tug nyiam rau nws sib npaug. Cov dej noo feem ntau nkag los ntawm qhov cua. Txawm li cas los xij, nws muaj peev xwm ua rau chav nkag mus txawm tias los ntawm cov phab ntsa sab nrauv ntawm lub tsev. Nyob rau hauv cov ntaub ntawv no, lub chav yuav txias thiab condense, uas yuav ua rau noo noo nyob rau hauv ib tug qauv.

tshuaj muaj zog thiab kab tiv thaiv

Nws tseem ceeb heev uas tiv thaivcov ntaub ntawv tsis ua rau corrosion ntawm cov khoom nyob ib puag ncig thaum sib cuag. Txawm li cas los xij, cov txheej tiv thaiv yuav tsum tiv taus cov khoom uas nws yuav los rau hauv kev sib cuag. Qhov no yog qhov tseem ceeb tshaj yog tias siv cov chemistry sib txawv.

Hnub no, cov khoom siv tiv thaiv niaj hnub no muaj peev xwm tiv taus cov kab, uas qee zaum kuj tuaj yeem ua rau muaj kev phom sij loj. Feem ntau ntawm tag nrho cov, xws li ib tug tiv thaiv txheej yog tsim nyog rau xws li cov ntaub ntawv thiab cov khoom los ntawm lawv li peat, straw, reed. Zes kab tsuag nyob rau hauv cov ntaub ntawv no yog ib tug ncaj ncees tshwm sim. Kev tiv thaiv me me rau lawv tuaj yeem ua tau txawm tias koj tus kheej tes. Hydrated txiv qaub yog zoo meej.

Human he alth

Ntau tus neeg xav paub yuav ua li cas thiab seb cov tshuaj tiv thaiv puas cuam tshuam rau tib neeg kev noj qab haus huv. Nws yog ib qho tsim nyog yuav tsum tau sau tseg ntawm no tias nws yog qhov teeb meem zoo los teb cov lus nug no kom meej, txij li cov tuam ntxhab ntawm cov tshuaj no feem ntau tsis nthuav tawm tag nrho cov npe ntawm cov khoom siv, nrog rau cov thev naus laus zis ntawm kev tsim, uas, hauv paus ntsiab lus, nkag siab.

Nyob rau hauv rooj plaub no, koj yuav tsum xyuam xim rau cov khoom tseem ceeb uas yog siv los tsim cov ntaub ntawv zoo li no. Feem ntau cov no yog cov nroj tsuag thiab cov ntxhia pob zeb. Tsis muaj kev phom sij ntawm cov tshuaj no rau tib neeg kev noj qab haus huv. Ntau qhov tsis ntseeg yog kev siv ntau yam khoom siv hluavtaws. Vim li no, nws yog ib qho tsim nyog los xyuas kom meej tias cov nyiaj no tau txais kev kho mob tshwj xeeb, uas yuav tsum tau txoKev phom sij rau tib neeg noj qab haus huv.

Piv txwv li, thaum tsim cov tshuaj tiv thaiv, cov khoom ntxhia tau ua tiav rau cov khoom me me uas thaum lawv siv ib txwm, thaum nqus tau, lawv yuav nkag mus rau hauv lub cev, ua rau muaj kev noj qab haus huv tsis zoo. Yog li ntawd, koj yuav tsum tau ua kom paub tseeb tias cov muaj pes tsawg leeg muaj ib tug binder uas yuav tiv thaiv cov ntxhia Cheebtsam los ntawm kev nkag mus rau hauv cov huab cua thaum siv. Hauv qhov no, tus neeg sawv cev tiv thaiv tuaj yeem suav tias muaj kev nyab xeeb.

Ib puag ncig thiab kev ua haujlwm

Ntxiv rau qhov cuam tshuam rau tib neeg lub cev, koj yuav tsum nco ntsoov tias cov tshuaj no yuav tsum tsis txhob muaj kev cuam tshuam rau ib puag ncig. Piv txwv li, kev siv cov cuab yeej tiv thaiv hauv kev tsim kho yog txwv rau qee lub sijhawm, txij li txhua qhov muaj pes tsawg leeg, txawm tias qhov zoo tshaj plaws, yuav sai lossis tom qab "loj hlob". Thaum qhov no tshwm sim, cov ntsiab lus no raug tshem tawm. Lawv raug coj mus rau tej qhov chaw pov tseg uas lawv raug hlawv. Tag nrho cov no ua rau qhov tseeb tias nws yog qhov zoo dua los siv cov ntxhia los yog cov khoom noj zaub rau cov neeg ua haujlwm tiv thaiv, vim lawv yuav tsis tawm cov tshuaj phem thaum hlawv.

Qhov kawg uas koj tuaj yeem ntxiv txog cov khoom siv tiv thaiv ib txwm yog tias lawv tau txuas los yog siv ntau txoj hauv kev. Feem ntau, cov txheej yog txuas nrog cov ntsia hlau, ntsia hlau lossis ntsia hlau. Piv txwv li, yog tias cov txheej tiv thaiv tau nthuav tawm nyob rau hauv daim ntawv ntawm lub phaj, ces nws yog pierced nrog rau tes, tom qab uas nws yog lined nrog ib tug nplaum.

Compositetshuaj

Cov ntaub ntawv sib xyaw yog cov khoom uas muaj ntau yam. Feem ntau cov qauv zoo li no: muaj ib lub hauv paus los yog cov yas-zoo li matrix, uas yog ntxiv dag zog nrog ntau yam fillers. Nyob ntawm qhov muab tub lim no, nws muaj peev xwm tsim tau cov txheej txheem ntau dua, tawv, tiv taus corrosion lossis ya raws. Hauv lwm lo lus, kev siv cov khoom sib xyaw ua ke los ua tus neeg sawv cev tiv thaiv tau zoo dua, vim tias kev tiv thaiv ntau yam cuam tshuam tuaj yeem ua tiav.

Raws li cov qauv ntawm cov tshuaj no, ob peb feem ntau yog siv. Cov no suav nrog fibrous, txheej, nanocomposite thiab lwm yam qauv. Fibrous hom composites feem ntau yog ntxiv nrog fibers ntawm cov khoom xav tau. Cov txheej txheem txheej txheem muaj daim ntawv "pie", qhov twg cov matrix thiab cov muab tub lim mus rau ib qho tom qab lwm hauv txheej.

Nws tseem yuav tsum tau hais tias cov ntaub ntawv tiv thaiv hluav taws xob feem ntau yog cov khoom sib xyaw, vim qhov no yuav tsum muaj kev tiv thaiv ntau tshaj plaws los ntawm ntau yam tsis zoo ib zaug.
