Tshuaj Txhaum Cai - Yuav Ua Li Cas Lub Hoobkas Nres Nres Tiv Thaiv Cov Khoom Siv Los Ntawm Ib puag ncig Degradation

Nres pads nyob hauv ib puag ncig hnyav. Lawv raug rau txoj kev ntsev thaum lub caij ntuj no, cov roj cav thiab cov dej txias, cov dej ntws ntws thaum lub sijhawm teeb tsa, thiab cov pa phem hauv huab cua. Nyob rau tib lub sijhawm, cov tshuaj no tuaj yeem ua rau cov khoom sib txhuam tsis zoo, ua rau poob ntawm kev ua haujlwm braking, suab nrov, lossis kev ua haujlwm tsis zoo. Txawm li cas los xij, feem ntau tom qab cov neeg yuav khoom yeej tsis xav txog tshuaj tiv thaiv thaum xaiv cov ntaub qhwv. Lub tuam txhab kev lag luam nres tsheb tsim nws cov ntaub ntawv tsis yog rau kev sib txhuam thiab hnav, tab sis kuj tiv thaiv cov tshuaj lom neeg uas cov ntaub qhwv tau ntsib thoob plaws hauv lawv lub neej. Kev nkag siab txog kev ruaj ntseg tshuaj pab koj xaiv cov ntaub qhwv uas tswj kev ua haujlwm hauv lub ntiaj teb tiag tiag, tsis yog hauv chav kuaj xwb.

Cov tshuaj hem thawj rau Nres Pads

Ntau yam khoom siv tuaj yeem tua cov ntaub ntawv sib txhuam txhuam:

· Txoj kev ntsev (sodium chloride, calcium chloride) - Siv hnyav rau lub caij ntuj no, ntsev yog hygroscopic thiab accelerates corrosion ntawm hlau fibers (steel, tooj liab). Corrosion khoom (xeb) nthuav dav, ua rau tawg thiab delamination. Ntsev kuj nkag mus rau hauv cov ntaub ntawv cob, ua rau nws tsis muaj zog thaum lub sijhawm.
· Nres Nres (DOT 3, DOT 4, DOT 5.1) - Glycol-ether lossis silicone-based kua yog cov kuab tshuaj muaj zog. Lawv tuaj yeem o lossis yaj qee cov khoom siv cob, txo cov shear zog thiab ua rau cov khoom sib txhuam kom muag los yog tawg.
· Cov roj cav thiab cov kua dej sib kis - Hydrocarbon roj nkag mus rau cov khoom sib txhuam ntxeem tau, txo kev sib txhuam coefficient thiab ua rau "greasy" xav. Lub ncoo tuaj yeem xav tau ntau qhov nres kom hlawv tawm cov kab mob.
· Coolant (ethylene glycol) - Qab zib thiab corrosive, coolant tuaj yeem tua cov resin-filler interface, ua rau micro-cracking thiab ceev hnav.
· Cov kua qaub los nag thiab kev lag luam poob - Sulphurous thiab nitrous tebchaw nyob rau hauv cov huab cua tuaj yeem hnov ​​​​mob nrog qee qhov muab ntim, hloov cov khoom sib txhuam.

Chemical Attack Manifests li cas

· Kev sib txhuam tsis zoo - Cov kab mob tsis huv poob 20-50% ntawm kev sib txhuam coefficient, ncua kev ncua deb.
· o lossis softening - Qee cov tshuaj ua rau lub ncoo o, ua rau caliper khi lossis hnav tsis sib xws.
· Cracking thiab spalling - Tshuaj-tsis muaj zog resin tsis tuaj yeem tuav cov khoom sib xyaw ua ke; Cov kab nrib pleb tshwm thiab nthuav tawm.
· Xwb jacking - ntsev-corroded steel fibers nthuav, thawb cov khoom sib txhuam kom deb ntawm lub phaj thaub qab.

Yuav ua li cas ib tug Professional Factory Engineers Chemical Resistance

1. Resin xaiv – Cov ntaub ntawv yog lub ncoo thawj tiv thaiv. Factories siv phenolic resins nrog kev sib txuas sib txuas siab, uas tsis tshua muaj permeable rau tshuaj. Qee qhov ntxiv epoxy lossis polyimide modifiers uas tiv thaiv o hauv cov dej nres thiab roj. Roj hmab-hloov cov resins, thaum zoo rau toughness, tej zaum yuav raug ntau dua rau cov roj nqus, yog li lub Hoobkas sib npaug.

2. Hydrophobic fillers - Qee qhov muab tso rau (kho graphite, mica, talc) tshem tawm cov dej thiab ntsev ntsev, txo cov dej noo. Lub Hoobkas qhia cov khoom ntim nrog cov dej nqus dej tsawg (<1% by weight) for applications in wet or winter climates.

3. Corrosion-inhibiting additives - Me me ntxiv ntawm zinc los yog tin tebchaw teb nrog chlorides, tsim cov yeeb yaj kiab tiv thaiv uas txo cov hlau fiber ntau corrosion. Qee lub tuam txhab siv zinc phosphate coatings ntawm cov hlau fibers ua ntej sib tov.

4. Dense structure – Low porosity reduces the surface area available for chemical penetration. Lub Hoobkas tswj kev nias siab thiab qhov loj me kom ua tiav qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.

5. Kev kuaj tshuaj ntsev - Ib lub Hoobkas tshaj lij ua pov thawj cov tshuaj tiv thaiv los ntawm kev nthuav tawm cov qauv ntsuas kom nrawm: ntsev tsuag (ASTM B117, 240 teev), nres cov kua dej rau hauv dej (24 teev), thiab roj immersion (24 teev). Tom qab kis tau, cov ntaub qhwv tau raug kuaj xyuas lub zog shear, kev sib txhuam coefficient, thiab pom qhov tsis xws luag. Kev lees txais yog tsim los rau txhua yam tshuaj.

Cov neeg yuav khoom yuav tsum nug dab tsi

Thaum ntsuam xyuas lub Hoobkas nres nres, nug:

· Koj puas kuaj tshuaj tiv thaiv? Koj siv txoj kev twg thiab cov tshuaj twg?
· Dab tsi yog qhov nqus dej ntawm koj cov khoom sib txhuam?
· Koj puas siv cov tshuaj tiv thaiv corrosion lossis hydrophobic fillers hauv koj cov qauv?
· Koj puas tuaj yeem muab cov tshuaj tsuag ntsev thiab cov kua dej tso rau hauv qhov ntsuas ntawm cov lej kuv xav xaj?

Factories uas tseem ceeb ntawm cov tshuaj tiv thaiv yuav muaj cov ntaub ntawv xeem los qhia. Cov uas tsis quav ntsej cov cuab yeej no tuaj yeem muag cov ntaub qhwv ntsej muag uas ua rau ntxov ntxov hauv lub ntiaj teb tiag tiag.

Qhov tseeb-Lub Ntiaj Teb Qhov Tseem Ceeb

Chemical degradation yog qhov tseem ceeb tshwj xeeb rau:

· Fleet tsheb – raug rau txoj kev ntsev thiab ntau yam kua dej ntau.
· Cov cheeb tsam ntug dej hiav txwv - Cov av noo siab thiab ntsev cua nrawm nrawm.
· Kev lag luam ib puag ncig - raug tshuaj lom neeg, plua plav, thiab roj.
· Cov tsheb uas muaj cov kua dej tsis tu ncua - cov tsheb qub lossis cov nkoj tsis zoo.

Kev Sib Tham Cov Neeg Siv Khoom

Raws li ib tug distributor, koj tuaj yeem qhia: "Peb cov ntaub qhwv tau raug sim los tiv thaiv ntsev, cov dej nres, roj, thiab cov dej txias - yog li lawv tswj kom nres lub zog txawm tias nyob rau hauv qhov chaw nyuaj tshaj plaws." Qhov no hais txog kev txhawj xeeb ntau tus neeg tsav tsheb thiab cov neeg tsav nkoj tsis tau xav txog tab sis yuav txaus siab thaum paub.

Kab hauv qab

Nres pads tsis yog cov tshuab sib txhuam xwb; lawv yog chemical barriers. Lub koom haum kev tshaj lij tiv thaiv nws cov ntaub qhwv los ntawm cov khoom hnyav uas lawv ntsib txhua hnub - los ntawm cov khoom siv hluav taws xob, kev xaiv muab tub lim, cov txheej txheem ntom ntom, thiab kev sim nruj. Thaum koj tau txais los ntawm lub Hoobkas uas muaj kev ruaj ntseg tshuaj, koj xa cov ntaub qhwv uas ua tau zoo txhua xyoo, los nag, ntsev, thiab nchuav - tiv thaiv koj cov neeg siv khoom thiab koj lub koob npe nrov.
