Kutheni Usebenzisa Ilaphu le-PTFE Lobushushu obuphakamileyo njengeLining eAnti-ukuMdla? 4 Izinto eziluncedo ezingundoqo

Kwizityalo zemichiza, iindawo zokucocwa, kunye neendawo zokucocwa kwamanzi amdaka, izixhobo zombane zijongana nemekobume ekhohlakeleyo: iiasidi ezomeleleyo, iialkali ezishushu, izinyibilikisi eziphilayo, kunye nobushushu obugqithisileyo. Iilayini zerabha ziyadumba kwaye ziqhekeke. FRP linings blister. I-corrodes yensimbi engenasici.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) yodlula ezi zixhobo zemveli. Ayinert ngokwekhemikhali, iyamelana nobushushu, izinzile ngokwemilinganiselo, kwaye ayinantonga – zonke zikwindawo enye.

I-Aokai PTFE ibonelele ngelaphu le-PTFE le-anti-corrosion lining applications amashumi eminyaka. Apha ngezantsi kukho iingenelo ezine eziphambili, kunye nemizekelo yesicelo sokwenyani.

Ukunganyanzeli kweMichiza-Kuxhathisa phantse yonke into

Eyona nzuzo ingundoqo ye-PTFE kukuxhathisa kwayo kwemichiza ekufutshane- jikelele. Ihlala ibizwa ngokuba 'nguKumkani wePlastiki' ngesizathu esihle.

1. Yintoni elichasayo

• Iiasidi ezomeleleyo: I-Sulfuri, i-nitric, i-hydrochloric, i-phosphoric, kunye ne -aqua regia (umxube we-nitric kunye ne-hydrochloric acids enyibilikisa igolide)

• Ialkalis ezomeleleyo: iSodium hydroxide, ipotassium hydroxide, iammonia

• Izinyibilikisi zendalo: Utywala, iiketones, iihydrocarbons ezinuka kamnandi (itoluene, ixylene), izinyibilikisi ezineklorini

• Ezinye izinto ezitshabalalisayo: ii-Oxidizers, iityuwa, kunye neekhemikhali ezininzi zemizi-mveliso

2. Yintoni engayixhathisiyo (imida)

• Iintsimbi ze-alkali ezinyibilikisiweyo (i-sodium, i-potassium) - ziya kutshabalalisa i-PTFE

• Igesi ye-fluorine kunye ne-fluorinating agents eyomeleleyo kumaqondo obushushu aphezulu

• I-Hydrofluoric acid (HF) - ihlasela i-fiberglass substrate ukuba i-coating ine-pinholes

Inqaku elisebenzayo: Kwinkonzo ye-hydrofluoric acid, sebenzisa ibakala elikhethekileyo le-HF-resistant okanye uqinisekise ukuba i-PTFE yokwambathisa ayinambhobho ngokupheleleyo (iipasile zokugquma ezininzi). I-Aokai PTFE ibonelela ngamabakala anjalo.

ULuhlu oluBanzi loBubushushu-Ukusuka kwiMkhenkce ukuya kubushushu obugqithisileyo

I-anti-corrosion linings idla ngokujongana neekhemikhali kuphela, kodwa ubushushu obugqithisileyo. Ilaphu le-PTFE liphatha iziphelo zombini zespectrum.

1. Ukusebenza okuphezulu kobushushu

• Ubushushu bokusebenza obuqhubekayo: -70°C ukuya kuma-260°C

• Incopho yexesha elifutshane: 350°C (uhambo olufutshane)

• Uvavanyo lokuguga olushushu: Emva kweentsuku ezingama-200 eziqhubekayo kwi-250 ° C, amandla oomatshini abonisa ukwehla okucacileyo.

2. Ukusebenza kobushushu obuphantsi

• Ihlala ibhetyebhetye ukuya kuthi ga kwi -70°C

• Inokumelana no -180°C (ubushushu benitrogen obumanzi) ngaphandle kokuqhekeka - nangona ukuguquguquka kuncitshisiwe

3. Kutheni le nto ibalulekile kwizicelo zelinen

Kwizixhobo ze-desulfurization, i-flue gas inokufikelela kwi-200-250 ° C. Iilayini zerabha zonakaliswa ngaphezu kwe-120°C. Ilaphu le-PTFE liyachuma. Kwi-cryogenic chemical processing (-50 ° C), i-PTFE ayibi brittle njengeeplastiki ezininzi.

IiPropati zoMzimba kunye nezoBuchwephesha-Zizinzile, zomelele, kwaye azinantonga

Ngaphaya kweekhemikhali kunye nokunganyangeki kwe-thermal, ilaphu le-PTFE libonelela ngeenzuzo ezininzi zoomatshini ezenza ukuba ibe yimathiriyeli egqwesileyo yomgca.

1. Uzinzo lweDimensional (deformation ephantsi)

I-fiberglass substrate inika ilaphu le-PTFE amandla okuqina aphezulu kunye nobude obuphantsi kakhulu - ngokuqhelekileyo <0.5% phantsi komthwalo. Ithetha ukuba:

• I-lining ayinwebeki okanye ihexa ngokuhamba kwexesha

• Akukho mibimbi okanye buckling ngenxa yokwanda thermal

• Uzigcina ziqinile eludongeni lwezixhobo

2. Umphezulu ongabambekiyo (ukucoca lula)

I-PTFE ye-friction coefficient isezantsi njenge- 0.05-0.1 . Izinto ezininzi azikwazi ukunamathela kumphezulu wayo. Kwi-anti-corrosion linings, oku kuthetha:

• Intsalela evela kwiikhemikhali ayenzeki kwi-lining

• Ukucoca phakathi kweebhetshi kukhawuleza - ngokuphindaphindiweyo ukuhlanjululwa kwamanzi

• Akukho 'ukubhaka kwi' kwiidipozithi zemichiza ezomisiweyo

3. Ukugquma kombane

• I-Dielectric rhoqo <2.6

• Ukuxhathisa umthamo ophezulu wevolumu (>10⊃1;⁵ Ω·cm)

• Ifanelekile kwi-insulating wraps kwizixhobo zombane kunye nombane apho ukukhuselwa kwe-corrosion kuyadingeka

4. Anti-ukuguga kunye nedangatye retardant

• Ukumelana nemozulu okugqwesileyo (Uzinzo lweUV)

• Ukungatsha-ukuzicima (UL94 V-0 rating eqhelekileyo)

• Akukho ukuthotywa okunokulinganiswa emva kweminyaka yokuvezwa ngaphandle

Isatifikethi seBanga lokutya-Ikhuselekile kuKutya kunye ne-Pharma

Ayizizo zonke iileyile ezichasene nokubola kufuneka zibe kumgangatho wokutya. Kodwa xa besenza-ekwenziweni kokutya, kumayeza, okanye kwizicelo zamanzi aselwayo - ilaphu le-PTFE liyahambisa.

1. Iziqinisekiso

• I-FDA 21 CFR 177.1550 - kuqhagamshelwano lokutya ngokuthe ngqo kunye nokungathanga ngqo

• Ummiselo we-EU 1935/2004 - kwizinto zoqhagamshelwano zokutya

• Ayinatyhefu, ayinavumba nakumaqondo obushushu aphezulu

• Akukho kukhutshwa kwezinto ezinobungozi ekutyeni okanye kumayeza

2. Apho kusetyenziswa ilineni lokutya

• Amaphepha okubhaka kunye nee-oven liners kwiibhaka zorhwebo (ezingeyontonga, ukucoca lula)

• Izixhobo zokuvelisa amayeza - iinqanawa zokuphendula kunye neetreyi zokumisa

• Amatanki okulungisa ukutya – apho ukutya okuneasidi okanye okuneoyile kunxibelelana nelinen

Iimeko zeSicelo esiQhelekileyo sokuNxulumana nokuMdla

Ngokusekwe kwezi zibonelelo zingentla, ilaphu le-PTFE lobushushu obuphezulu lisetyenziswa kakhulu kwezi ndawo zilandelayo:

1. Ukukhuselwa kweekhemikhali kunye nokusingqongileyo

• Imibhobho yepetrochemical - intambo yangaphakathi yokuthintela ukubola kwioyile ekrwada, iimveliso ezisulungekisiweyo kunye negesi emuncu.

• Izixhobo ze-Desulfurization (izityalo zamandla) - umgca we-scrubbers, i-ductwork, kunye neetshimini apho i-flue gas iqulethe i-SOₓ kunye ne-HCl

• Iinqanawa zokusabela kunye neetanki zokugcina - uphahla lwamatanki abambe i-acids egxininisiweyo, iialkali, okanye izinyibilikisi ezinobundlobongela

• Amatanki okuvunwa (ukulungiswa kwentsimbi) - ukufakwa kweitanki eziqulethe i-hydrochloric okanye i-asidi yesulfuric yokucoca isinyithi

Idatha yommandla evela kwi-Aokai PTFE: Kwinqaba ye-desulfurization yeplanti yamandla, ilaphu lelaphu le-PTFE lithathe iminyaka emi-3 ngaphandle kokusilela. Ukufakwa kwerabha ngaphambili kuthathe iinyanga ezili-9 kuphela. Oko kukwandisa ubomi be-4x.

2. Ishishini lokutya kunye namayeza

• Amaphepha okubhaka kunye ne-oven liners - non-stick, ucoceko olulula, oluhambelana ne-FDA

• Iigaskets zeMicrowave - ukumelana nobushushu kunye nokungagxili

• Izixhobo zokuvelisa amayeza - iilinen zokomisa iitreyi, iinqanawa zokuxuba, kunye neepani zokugquma iipilisi

3. Oomatshini kunye ne-elektroniki

• Iibhanti zokuhambisa ubushushu obuphezulu kwi-photovoltaic laminators - dibanisa i-anti-corrosion kunye ne-non-stick kunye nokumelana nobushushu.

• Iipleyiti zokutywina zobushushu – ilaphu le-PTFE njengesigqubuthelo esingeyontonga

• Iintambo zokufakelwa kombane - apho zombini ukugquma kunye nokukhuselwa kwe-corrosion kuyadingeka

Isishwankathelo - Kutheni ukhetha i-PTFE Fabric ye-Anti-Corrosion Lining

I-Aokai PTFE yenza ilaphu le-PTFE elinobushushu obuphezulu ngokukodwa kwi-anti-corrosion lining applications. Sinikezela ngobubanzi besiko, ubukhulu (0.08mm ukuya ku-0.40mm), kunye namabakala aqinisekisiweyo yi-FDA. Qhagamshelana nathi ngemekobume yakho yeekhemikhali, uluhlu lobushushu, kunye nemilinganiselo yesixhobo ukuze ufumane isindululo somgca.
