Vim li cas thiaj siv PTFE High-Temperature Npuag li Anti-Corrosion Lining? 4 Qhov Zoo Tshaj Plaws

Hauv cov nroj tsuag tshuaj, refineries, thiab cov chaw kho dej khib nyiab, cov khoom siv hauv ob sab phlu ntsib qhov chaw phem: muaj zog acids, kub alkalis, organic solvents, thiab kub heev. Rubber linings o thiab tawg. FRP linings blister. Stainless hlau corrodes.

PTFE high-temperature npuag (PTFE-coated fiberglass) outperforms cov tsoos ntaub ntawv. Nws yog chemically inert, tshav kub-resistant, dimensionally ruaj khov, thiab tsis-stick - tag nrho nyob rau hauv ib tug.

Aokai PTFE tau muab PTFE ntaub rau cov ntaub ntawv tiv thaiv corrosion rau ntau xyoo lawm. Hauv qab no yog plaub qhov txiaj ntsig tseem ceeb, ntxiv rau cov qauv siv tiag tiag hauv ntiaj teb.

Chemical Inertness - Resisnts yuav luag txhua yam

Lub ntsiab kom zoo dua ntawm PTFE yog nws ze-universal tshuaj tsis kam. Nws feem ntau hu ua 'King of Plastics' rau qhov laj thawj zoo.

1. Nws resists dab tsi

• Cov kua qaub muaj zog: sulfuric, nitric, hydrochloric, phosphoric, thiab txawm tias aqua regia (ib qho sib xyaw ntawm nitric thiab hydrochloric acids uas yaj kub)

• Muaj zog alkalis: Sodium hydroxide, potassium hydroxide, ammonia

• Organic kuab tshuaj: Cawv, ketones, muaj ntxhiab hydrocarbons (toluene, xylene), chlorinated kuab tshuaj

• Lwm yam corrosives: Oxidizers, ntsev, thiab feem ntau muaj tshuaj lom neeg

2. Dab tsi nws tsis tiv thaiv (kev txwv)

• Molten alkali hlau (sodium, potassium) - yuav rhuav tshem PTFE

• Cov roj fluorine thiab cov tshuaj fluorinating muaj zog ntawm qhov kub thiab txias

• Hydrofluoric acid (HF) - tawm tsam cov fiberglass substrate yog tias txheej muaj pinholes

Lus Cim: Rau kev pabcuam hydrofluoric acid, siv qib tshwj xeeb HF-tiv taus lossis ua kom cov PTFE txheej tsis muaj pinhole (ntau txheej dhau). Aokai PTFE muaj cov qib zoo li no.

Dav Kub Kub - Los ntawm khov mus rau huab cua kub heev

Anti-corrosion linings feem ntau ntsib tsis tsuas yog tshuaj, tab sis kub heev. PTFE npuag tuav ob qhov kawg ntawm spectrum.

1. Kev ua haujlwm siab kub

• Ua haujlwm kub tsis tu ncua: -70 ° C txog 260 ° C

• Lub sij hawm luv luv: 350 ° C (kev mus ncig luv luv)

• Thermal aging test: Tom qab 200 hnub txuas ntxiv ntawm 250 ° C, txhua yam muaj zog qhia tsis pom qhov poob qis

2. Kev ua haujlwm kub qis

• Tseem hloov tau mus rau -70 ° C

• Muaj peev xwm tiv taus -180 ° C (kua nitrogen kub) yam tsis muaj kev tawg - txawm tias qhov yooj yim txo

3. Vim li cas qhov no tseem ceeb rau daim ntawv thov hauv ob sab phlu

Hauv cov khoom siv desulfurization, cov roj flue tuaj yeem ncav cuag 200-250 ° C. Roj hmab hauv ob sab phlu degrade tshaj 120 ° C. PTFE ntaub thrives. Hauv kev ua cov tshuaj cryogenic (-50 ° C), PTFE tsis ua nkig zoo li ntau cov yas.

Lub cev thiab cov cuab yeej cuab tam - ruaj khov, muaj zog, thiab tsis-nplaum

Tshaj li tshuaj lom neeg thiab thermal tsis kam, PTFE ntaub muaj ntau yam kev pab cuam uas ua rau nws yog ib qho khoom siv zoo heev hauv ob sab phlu.

1. Dimensional stability (tsawg deformation)

Lub fiberglass substrate muab PTFE npuag siab tensile lub zog thiab qis heev elongation - feem ntau <0.5% nyob rau hauv load. Qhov no txhais tau tias:

• Lub hauv ob sab phlu tsis ncab los yog sag dhau sijhawm

• Tsis wrinkling los yog buckling vim thermal expansion

• Ua kom nruj haum rau cov khoom siv phab ntsa

2. Non-stick nto (yooj yim ntxuav)

PTFE qhov kev sib txhuam coefficient yog tsawg li 0.05-0.1 . Feem ntau cov tshuaj tsis tuaj yeem ua raws li nws qhov chaw. Rau anti-corrosion linings, qhov no txhais tau tias:

• Cov residue los ntawm cov tshuaj tiv thaiv tsis tsim nyob rau hauv ob sab phlu

• Kev ntxuav ntawm cov khoom siv ceev ceev - feem ntau tsuas yog yaug dej xwb

• Tsis muaj 'baking on' ntawm qhuav tshuaj deposits

3. Hluav taws xob rwb thaiv tsev

• Dielectric qhov tsis tu ncua <2.6

• Siab ntim resistivity (> 10⊃1; ⁵ Ω·cm)

• Haum rau insulating wraps nyob rau hauv cov khoom siv hluav taws xob thiab hluav taws xob qhov chaw tiv thaiv corrosion kuj xav tau

4. Anti-aging thiab nplaim retardant

• Cov huab cua tsis zoo (UV ruaj khov)

• Tsis-flammable - self-extinguishing (UL94 V-0 ntsuam xyuas raug)

• Tsis muaj kev ntsuas degradation tom qab xyoo ntawm kev raug sab nraum zoov

Food-Qib Certification – Safe for Food and Pharma

Tsis yog txhua qhov kev tiv thaiv corrosion yuav tsum yog zaub mov qib. Tab sis thaum lawv ua - hauv kev ua zaub mov, tshuaj, lossis dej haus - PTFE npuag xa.

1. Cov ntawv pov thawj

• FDA 21 CFR 177.1550 - rau kev sib cuag zaub mov ncaj qha thiab tsis ncaj

• EU Txoj Cai 1935/2004 - rau cov khoom noj khoom haus

• Tsis muaj tshuaj lom, tsis muaj ntxhiab tsw txawm nyob hauv qhov kub thiab txias

• Tsis muaj leaching ntawm cov teeb meem tshuaj rau hauv cov khoom noj los yog tshuaj

2. Qhov twg siv cov ntaub ntawv qib zaub mov

• Cov nplooj ntawv ci thiab qhov cub liner hauv kev lag luam bakeries (tsis yog-stick, yooj yim tu)

• Cov khoom siv tshuaj ntau lawm - cov tshuaj tiv thaiv cov hlab ntsha thiab cov tais kom qhuav

• Khoom noj khoom haus tso tsheb hlau luam - qhov twg acidic los yog oily zaub mov tiv tauj rau hauv ob sab phlu

Daim Ntawv Thov Kev Sib Tham rau Kev Tiv Thaiv Kev Tiv Thaiv Kab Mob

Raws li qhov zoo saum toj no, PTFE high-temperature ntaub yog dav siv hauv cov nram qab no:

1. Tshuaj thiab ib puag ncig tiv thaiv

• Petrochemical pipelines - hauv ob sab phlu los tiv thaiv corrosion los ntawm cov roj crude, refined khoom, thiab roj qaub

• Cov khoom siv desulfurization (fais fab nroj tsuag) - hauv ob sab phlu rau scrubbers, ductwork, thiab chimneys qhov twg flue gas muaj SOₓ thiab HCl

• Cov hlab ntsha thiab cov tso tsheb hlau luam - hauv ob sab phlu rau cov tank tuav cov kua qaub, alkalis, lossis cov kuab tshuaj hnyav

• Pickling tso tsheb hlau luam (steel processing) - hauv ob sab phlu rau cov tso tsheb hlau luam uas muaj hydrochloric lossis sulfuric acid rau kev ntxuav hlau

Teb cov ntaub ntawv los ntawm Aokai PTFE: Nyob rau hauv ib lub zog cog desulfurization ntauwd, PTFE ntaub hauv ob sab phlu kav 3 xyoos yam tsis ua hauj lwm. Rubber txheej yav dhau los tsuas yog 9 lub hlis xwb. Qhov ntawd yog 4x lub neej txuas ntxiv.

2. Kev lag luam khoom noj thiab tshuaj

• Cov ntawv ci thiab qhov cub liner - tsis yog-stick, yooj yim huv, FDA ua raws

• Microwave gaskets - tshav kub-resistant thiab tsis-stick

• Cov khoom siv tshuaj ntau lawm - cov ntaub ntawv rau cov tais kom qhuav, sib xyaw cov hlab ntsha, thiab cov ntsiav tshuaj txheej lauj kaub

3. Machinery thiab electronics

• High-temperature conveyor siv rau photovoltaic laminators - ua ke los tiv thaiv corrosion nrog tsis-stick thiab kub tsis kam

• Thaum tshav kub kub sealing daim hlau - PTFE ntaub li tsis-stick cover

• Hluav taws xob insulating liners - qhov twg ob qho tib si rwb thaiv tsev thiab kev tiv thaiv corrosion yuav tsum tau
