Polymerization process hrang hrang (suspension polymerization leh dispersion polymerization) hmanga siam PTFE emulsion te hi eng nge an danglamna?

Thuhmahruai chu a Teflon High-Temperature Fabric siamtute chuan Polymerization Process hrang hrang (Suspension Polymerization leh Dispersion Polymerization) hmanga siam PTFE Emulsions Inthlauhna

I. Concept hrang hrangte sawifiahna hmasa ber

Industrial practice-ah chuan suspension polymerization hian direct-in PTFE emulsion a siam thei lo. PTFE emulsion dik tak (dispersion) hi dispersion polymerization (a bul berah chuan emulsion polymerization a ni) hmang chauha siam a ni. Jiangsu Teflon High-Temperature Fabric Manufacturer chuan sumdawnna atana hman theih 'suspension-method PTFE emulsion' chu a takah chuan suspension-polymerized resin micropowders mechanically dispersing hmanga siam aqueous suspension a ni tih a sawi. An pahnih hian a bulpui berah an danglam a, particle nature atanga end-use application thlengin.

II. Dispersion Polymerization: PTFE Emulsion hmasa ber a ni

1. Particle Morphology leh Stability chungchang

Particle te hi a spherical tha tawk a, primary particle (0.05–0.5 μm) te chu secondary particle ah agglomeration atanga siam niin, particle size 0.1–0.3 μm leh size distribution te tak te pawh a tawi hle. Stability hi polymerization laiin perfluorinated surfactants (PFOA alternatives) dah belh a ni. Colloidal system hi stratification tel lovin kum tam tak chhung chu a nghet thei a, mechanical shear laka invenna tha tak a nei bawk.

2. Molecular Weight leh Film siam dan

Molecular weight hi a sang hle (million engemaw zat thleng), crystallinity 94% aia tam a ni a, fibrillation capacity a chak hle bawk. Coating hnuah 380°C vel a high-temperature sintering a ngai a, chutih lai chuan particle te chu anti-corrosion leh non-stick property tha tak nei, continuous, dense, leh tough film ah an fuse a ni.

3. Processing leh A hman dan tlangpui

Processing hi paste extrusion, impregnation, emaw coating hmanga tihkhawtlai a ni a, chu chu sintering hmanga tih a ni. A hmanna tlangpui chu non-stick cookware coatings, fiberglass architectural membrane impregnation, microporous ePTFE membrane (breathable leh waterproof), leh high-end capacitor film te a ni.

III. Suspension Polymerization Micropowders: Tui hmanga siam (Emulsion tia vuah dik lo fo) .

1. Particle Morphology leh Stability chungchang

Jiangsu Teflon High-Temperature Fabric Manufacturer-in a sawi angin: Particle te hi suspension-polymerized pellets grinding leh crushing hmanga siam a ni a, chu chuan polyhedral shape mumal lo tak, particle size 2 atanga 20 μm inkar leh size distribution zau tak a siam a ni. He system hi thermodynamically unstable a ni a, sedimentation leh stratification a tam hle. Sedimentation tihkhawtlai nan conventional surfactant leh thickeners xanthan gum leh cellulose ethers te dah tel a ngai a, hman hmain uluk taka stirring a ngai bawk.

2. Molecular Weight leh Film siam dan

Molecular weight hi a hniam deuh (sawm tam tak atanga sang tam tak) thlenga siamrem theih a ni a, brittleness nasa zawk leh fibrillation capacity chak lo tak a ni. Coating hnuah chuan dry lubricating layer siam nan ambient emaw low-temperature drying chauh a ngai a; film-ah sinter theih a ni lo.

3. Processing leh A hman dan tlangpui

Formulation-ah direct-a dah theih a ni a, coating leh air-dried hmanga hnawih theih a ni bawk. A hmanna tur chu industrial lubricant additives, rubber leh plastic mold release agents, ink leh coatings atana anti-wear leh slip agents, textiles atana water-repellent finishing te a ni.
