Aboafo a Wɔtaa De Di Dwuma wɔ PTFE Emulsion Impregnation mu – Akwankyerɛ a Edi Mu

PTFE emulsion impregnation ne ade titiriw a wɔfa so yɛ PTFE ntama a ɛyɛ hyew kɛse . Base PTFE dispersion nkutoo nyɛ bere nyinaa na ɛyɛ nsu, ɛhyɛn mu, anaasɛ ɛkyekyere fiberglass ntama pɛpɛɛpɛ.

Aokai PTFE ayɛ impregnation formulations a ɛyɛ papa wɔ nneɛma pii mu. Saa akwankyerɛ yi kyerɛkyerɛ aboafoɔ awotwe a wɔtaa de di dwuma no mu – deɛ wɔyɛ, sɛdeɛ wɔyɛ adwuma, ne berɛ a wɔde bedi dwuma.

Nneɛma a ɛma nsuo ne nea ɛhyɛn mu – The Core Additive

Raw PTFE emulsion wɔ soro tension a ɛkɔ soro kakra, na ɛma entumi nkɔ nhama ne ntama mu yiye. Nneɛma a ɛma nsuo yɛ nwini no brɛ nsuo a ɛwɔ soro no ase, na ɛma emulsion no trɛw na ɛhyɛn mu yie.

Thickeners ne Rheology Modifiers – Ɛhwɛ Coating Pick-Up so

Thickeners sesa emulsion viscosity na asiw dripping na hwɛ pɛpɛɛpɛ coating thickness.

Afotu a mfaso wɔ so: Sɛ wopɛ sɛ wode nneɛma a ɛyɛ tratraa na ɛyɛ pɛ kata ntama a wɔanwene no denneennen so a, fa nnuru a ɛnyɛ den pii a ɛnyɛ den pii di dwuma. Sɛ wopɛ ntama a emu yɛ duru a wɔde kata so anaa ntama a wɔabue ano a, ma thickener no nkɔ soro na ama woatumi ahwɛ sɛnea ɛbɛkɔ mu no mu dɔ.

pH Regulators ne Emulsion Stabilizers Nneɛma a Wɔde Yɛ Adwuma

Mpɛn pii no, wɔde anionic surfactants na ɛma PTFE emulsions no gyina pintinn na wɔma ɛkɔ so yɛ pH 9-10 na amma coagulation asiw ano.

• Ammonia nsuo (28 wt%): Ɛyɛ regulator a wɔde di dwuma kɛseɛ. Ɛyɛ hyew koraa bere a ɛreyow/ɛreyɛ ayɛ hyew no, na ennya nkae biara a ɛbɛma adwumayɛ asɛe.

Adhesion Promoters – Bonding Resins ne Nneɛma a ɛka bom

Pure PTFE wɔ mmerɛw kɛse bonding tumi ne substrates. Nneɛma a ɛma obi bata ho no ho hia.

1. Silane nneɛma a wɔde ka bom

• Nhwɛso ahorow: Aminosilane (KH-550), epoxy silane.

• Ɔkwan a wɔfa so yɛ adwuma: Wɔ hydrolysis akyi no, wɔne fiberglass – Si-O-Si nkitahodi a ɛda silane ne glass ntam, ne organic functional groups a ɛne PTFE anaa polymers afoforo di nkitaho no yɛ nnuru nkitahodi.

2. Ɔhyew a ɛkorɔn a ɛko tia bonding resin dispersions

• Nhwɛso ahorow: Polyamide-imide (PAI), polyphenylene sulfide (PPS), polyethersulfone (PES) a wɔde petepete nsu mu.

• Dwumadi: Core nneɛma ma non-stick coatings ne common binders ma impregnated fiberglass filter media ne membrane nneɛma. Wɔma adhesion ne cohesion tu mpɔn wɔ composite a etwa to no mu.

Film-Forming Aids – Ɛbrɛ Sintering Ɔhyew ase

PTFE wɔ melt viscosity a ɛkorɔn yiye. Mmoa a wɔde yɛ sini ma nneɛma nketenkete a wɔde bom yɛ mmerɛw bere a wɔreyɛ sintering no.

• PFA (perfluoroalkoxy resin) – nsuo a ɛyɛ mmerɛw a ɛba fam sen PTFE

• FEP (fluorinated ethylene propylene copolymer) – nea ɛba fam a ɛyɛ hyew sen PTFE

Saa melt-processable fluoropolymers yɛ molten bonding phases ntam PTFE asinasin bere a sintering, boosting coating compactness ne interfacial adhesion. Wɔn ho wɔ mfaso titiriw ma nneɛma a wɔde kata so a ɛyɛ den anaasɛ bere a wɔpɛ sɛ sintering hyew a ɛba fam no.
