I fale kemisi, o paipa ma va'a o lo'o feagai ma osofa'iga faifaipea mai fa'asalalauga fa'amalosi - malosi malosi, vai vevela, so'o so'o, ma ausa. PTFE lipine o se fofo masani mo anti-corrosion, non-stick, ma faamaufaailoga puipuiga. Ae o le filifilia o le lipine sa'o e le faigofie e pei o le filifilia o le fua maualuga o le vevela.
Ua saunia e Aokai PTFE lipine PTFE mo talosaga vailaʻau mo le tele o tausaga. O lenei ta'iala o lo'o fa'amatalaina ai le fa'atulagaga e tolu-vaega o le lipine PTFE, ta'iala autu filifilia (vevela, fa'asalalauga kemisi, mana'oga fa'ainisinia), ma ta'iala faufale taua.
Le tolu-Layer fausaga o le PTFE maualuga-vevela Tape
Ole fa'atinoga atoa ole lipine PTFE fa'atau pisinisi e fa'atatau ile tolu fausaga fa'avae:
Fa'afuafuaga
Mea masani
A'afiaga ile Filifiliga o Oloa
Lau'ele'ele galuega fa'atino
Ata PTFE mama / PTFE-impregnated fiberglass ie
Pulea meatotino e le pipii, vailaau kemikolo, ma le maualuga o le vevela
Fa'amalosia mea'ai
Leai (ata mama) / Ie Fiberglass / Ie Aramid
Fuafuaina le malosi faʻainisinia, teteʻe teteʻe, ma teteʻe puncture
Papa pipii
Silicone PSA, Acrylic PSA, Rubber-based PSA
Fa'atulaga le tapula'a o le vevela pito i luga ma le fa'ama'i kemikolo o le lipine atoa; e masani lava ole feso'ota'iga sili ona vaivai
Malamalamaga taua: E ui lava o le PTFE lava ia e mafai ona galue malosi mai le -190 ° C i le 260 ° C mo se taimi umi, o le faʻapipiʻi o le bottleneck faʻatinoga . Filifili le faʻapipiʻi faʻavae i luga o le siosiomaga auaunaga moni, ae le na o le PTFE luga.
Fa'atonuga Filifilia Autu ma Mataupu Faavae Faafetaui
1. O le vevela o galuega - o le fa'apipi'i filifilia o le fa'amuamua pito i luga
Va'aiga vevela
Fa'apipi'i Fautuaina
Aisea
200°C – 260°C (taimi umi)
Silicone PSA (mana'omia)
Na'o le fa'apipi'i fa'apipi'i e fa'atumauina le tackiness mautu i lenei laina; itiiti toega pe a uma ona pa'u
120°C - 180°C fa'atasi ai ma so'o fa'asusu & suau'u tete'e
PSA acrylic vevela maualuga
E sili atu le malosi o le fusi nai lo le silicone, ae vave ona paʻu ile 260°C
I lalo ifo o le 100°C
Acryl masani po'o fa'avae pa'u
Talia, ae seasea i siosiomaga kemisi
Aokai PTFE faʻamatalaga: Mo talosaga i le 200 ° C +, PSA acrylic e le taliaina - o le a faʻaleagaina, faʻamalulu, ma mafua ai le paʻu o le lipine. Silicone na o le pau lea o le filifiliga talafeagai.
2. Fa'asalalauga vaila'au - fetaui lelei i le va o mea fa'apipi'i ma mea'ai
O lo'o fa'aalia e le PTFE vaega fa'atino e toetoe lava a fa'a'a'ala'au uma (sei vagana ai metala alkali u'amea ma le kasa fluorine maualuga-vevela). Ae ui i lea, o ala o vailaau kemikolo e ati mai i pito lipine ma tafi sa'o ai le vaega pipii.
Fa'asalalauga Fa'a-Kemisi
Fa'apipi'i Fautuaina
Fa'aeteete
Ole malosi fa'aletino (HCl, H₂SO₄ ≤80%), alkalis malosi (NaOH), brine, ausa vai
Ua fufula le silikoni i so'o so'o; e fautuaina le acrylic, ae faʻamaonia le fua o le vevela (masani ≤150°C)
Ausa maualuga ma le maualuga o le ausa/alkali (su'i fa'aalia)
Suia silicone PSA + fa'a'amilosaga fa'atele
Tulaga sili ona faigata - e mafai ona fa'asusu le silicone; fa'amalosia i le fa'a'ami'i fa'ato'aga
Mo le vevela e sili atu i le 150°C fa'atasi ai ma solvents organic: Fa'aoga masini fa'apipi'i po'o le fa'alu-ve'ese vevela mama-ma'o PTFE lipine/fa'agaau.
Fa'atatauga Fa'atatau ma Filifiliga Fa'asaienisi Fa'atatau

PTFE mama ata / fiberglass ie fa'atasi ma vaila'au fa'apipi'i acrylic
O ata tifaga mama e vavaeeseina ai ala oona; ie fiberglass e fa'aleleia ai le malosi; o sooga vae e manaʻomia le faʻamalosia o le tele o mea
Taiala Fausia ma le Saogalemu
1. Fa'asagaga i luga ole laiga - o le fa'avae o le fa'apipi'i
E mana'omia le fa'amama atoatoa, aveese le 'ele, ma fa'agogo. Solo o luga i le acetone po'o le ava malosi ona soso'o ai lea ma le taoina o le afi vave e fa'atele ai le malosi fa'apipi'i. O lenei mea e aveese ai mea leaga ma fa'agaoioia le u'amea mo le pipii maualuga.
2. Fa'apa'i ma fa'a'ami'i
Ole la'ititi ole 2-3 ta'amilosaga e mana'omia mo le puipuiga o vaila'au fa'atasi ai ma le 50% fa'apipi'i ile li'o. E tatau ona fa'amalosia pito fa'amau i lipine PTFE fa'afetaui po'o uaea uaea uamea e puipuia ai le pa'u atoa pe a uma ona fa'apipi'i e ala fa'asalalau.
3. Saogalemu tulaga - o afea e aloese ai mai le tape PTFE atoa
Mo fa'asalalauga mata'utia o lo'o mulimuli mai, o lipine uma o lo'o i ai mea fa'apipi'i fa'aola e le saogalemu :
Hydrogen fluoride (HF)
Fa'apuna le alkali malosi (>80%)
Chlorine trifluoride (ClF₃)
Su'ega: Su'i i le PTFE fa'apipi'i atoa po'o le fa'apipi'i fa'apipi'iina (leai se pipi'i).
4. Fa'asagaga fa'atete'e ma fa'asa-pa
Afai o le paipa e momoli atu mea e mu ma e mafai ona tupu, filifili le lipine PTFE anti-static (e masani ona uliuli pogisa ma le kaponi faatumu, luga resistivity 10⁶-10⁹ Ω) e fa'amama ma le saogalemu.
