E fa'afefea ona fa'a'ese'ese fa'ama'i ole PTFE ie maualuga-vevela?

I fale kemisi, laina eletise, ma semiconductor fabs, meafaigaluega e masani ona faʻaalia i acids malosi, alkalis, ma solvents. O le filifilia o mea puipui sa'o e a'afia ai le saogalemu ma le ola o meafaigaluega.

PTFE (polytetrafluoroethylene) e masani ona taʻua o le 'tupu palasitika' ona o lona inertness matautia vailaau. Ae o le 'inert' e le o lona uiga o le 'le mafai ona faatoilaloina' - o fea vaila'au e mafai ona fa'aleagaina? E fa'afefea ona a'afia le vevela ma le fa'atonuga o lona fa'atinoga?

I Aokai PTFE , ua matou faʻaaluina le tele o tausaga o suʻega PTFE-faʻapipiʻiina ie e faasaga i siosiomaga kemisi moni-lalolagi. O lenei tusiga o loʻo faʻasoa a matou sailiga e fesoasoani ia te oe e filifili ma le poto.

Vailaau Mata'utia e Tete'e ie ie vevela PTFE

1. Aisa Malosi

PTFE ie e maua ai le tete'e lelei i:

• Sulfuric acid (H₂SO₄)

• Nitric acid (HNO₃)

• Su'i suka (HCl)

• phosphoric acid (H₃PO₄)

• Ole maualuga ole fa'ama'i fa'ama'i pei ole aqua regia ma le hydrofluoric acid (HF)

2. Alkali Malosi

E tetee i le sodium hydroxide (NaOH), potassium hydroxide (KOH), vai ammonia (NH₃·H₂O), ma isi mea malosi alkaline.

3. Solvent Organic

Fa'atekinisi e fa'asaga i le tele o so'o so'o, e aofia ai ava malosi (methanol, ethanol), ketones (acetone, MEK), hydrocarbons manogi (benzene, toluene, xylene), ma penisini.

4. Isi Vailaau Matautia

Fa'amautu le fa'atinoga fa'asaga i mea fa'ama'i (fa'ata'ita'iga, hydrogen peroxide), masima (sodium chloride, sodium sulfate), ma kasa pala (chlorine, hydrogen sulfide).

Tapula'a – Vailaau Fa'aleaga e Fa'aleagaina Ie PTFE

E ui lava i le maualuga o le tetee atu i kemikolo, o le ie vevela maualuga o le PTFE e iai tapulaʻa i lalo o le maualuga o le vevela poʻo tulaga maualuga. O nai vaila'au fa'apitoa e ono fa'aleagaina e pei ona ta'ua i lalo:

E le gata i lea, le ie ufiufi PTFE mo le faʻaaogaina ma: e le fautuaina

• Chlorine trifluoride (ClF₃) – e mafai ona tupu fa'afuase'i

• Oxygen difluoride (OF₂) – fa'atupu vevesi

• Suavai pe kasa fluorine (F₂) i le maualuga o le vevela - osofaʻia le PTFE

Fa'aAafiaga Fa'aa'afia Fa'asa'o Fa'ama'i o le PTFE fa'apipi'i ie

Le tele o mea e aʻafia ai le faʻafefeteina o le PTFE maualuga-vevela ie i talosaga moni-lalolagi:

• Vevela: O lo'o tumau pea le fa'atinoga o vaila'au i totonu -70°C i le 260°C. E fa'aitiitia le tete'e i vaila'au fa'apitoa i le maualuga o le vevela.

• Fa'atotonuga: O le faatofuina mo se taimi umi i ala fa'a'ele'ele maualuga e ono fa'aleagaina ai meafaitino. E fautuaina le su'ega ile nofoaga.

• Fa'amamago fa'ainisinia: Fa'atasiga fa'ama'i fa'ama'i ma fe'ese'ese fa'ainisinia e fa'avavevave ai le matua. O le puipuia o le paluga PTFE mai le maosiosia e taua tele - a faʻaleagaina, o le alava tioata o loʻo i lalo o le a faigofie ona afaina.

• Umi ole fa'aaliga: E ese le tete'e o le sausau mo taimi pupuu mai le faatofu faifai pea.

• Omiga: O le maualuga o le mamafa e mafai ona faʻamalosia vailaʻau i totonu o pores microscopic poʻo faʻaletonu faʻapipiʻi.

O fa'amatalaga lab a Aokai PTFE o lo'o fa'aalia ai o le synergy vevela-fa'asa'o e masani ona manatu faatauvaa. Mo se faʻataʻitaʻiga, ie PTFE e tumau tausaga i le 50% sulfuric acid i le 100 ° C e mafai ona faʻaalia le paʻepaʻe luga i totonu o masina i le 200 ° C ma le faʻaogaina tutusa. Fa'aaoga i taimi uma se laina saogalemu.

Aotelega - Tete'e Vailaau o le PTFE High-Temperature Ie

Mo le tele o siosiomaga kemikolo alamanuia, PTFE coated ie e maua ai le fa'atuatuaina, fa'atino umi. Ae ui i lea, ia faʻamaonia i taimi uma le fetaui i lalo o tulaga faʻaogaina - aemaise lava le vevela, faʻatonuga, ma le faʻalavelave faʻainisinia.

I le aotelega o , le ie vevela maualuga o le PTFE e ofoina atu le tetee mataʻina i le toetoe o mea uma, alkalis, ma solvents organic i totonu o lona tulaga masani galue (-70°C i le 260°C). O tuusaunoaga autu o u'amea alkali liusuavai ma vaila'au fa'afefete malolosi. E mana'omia fo'i le fa'aeteete atili o vaila'au fa'ama'i fa'asa'o vevela.

I le fa'atinoga, e galulue fa'atasi le vevela, fa'atonuga, ma le mamafa fa'ainisinia e a'afia ai le olaga faaletino. Mo tulaga ogaoga, matou te fautuaina le su'ega i luga ole laiga po'o le fa'aogaina o le 30-40°C i lalo ole vevela maualuga.

Mana'omia se fesoasoani ile siosiomaga fa'apitoa ole vaila'au? Aokai PTFE ua tu'ufa'atasia fa'amaumauga a'afia mo le faitau selau o fa'asalalauga. O le 'au fa'atekinisi a Fa'afeso'ota'i i matou mo ta'iala filifilia po'o fa'ata'ita'iga fa'apipi'i ie fa'apipi'i PTFE fofo.
