Polytetrafluoroethylene (PTFE) hmanga lei chunglam enkawl dan .

PTFE high-temperature fabrics siamtu professional source a nih angin Jiangsu Aokai New Materials chuan polytetrafluoroethylene (PTFE) surface treatment a rawn pholang dawn a ni.

PTFE hian temperature sang leh hniam laka invenna tha tak a nei a, chemical corrosion resistance ropui tak a nei a, friction coefficient hniam tak a nei a, self-lubricating property a nei bawk. Electronics, machinery, chemical equipment, aerospace, biomedicine leh thil dang dangah te hman a ni nasa hle a, tih hmingthanna a hlawh chhuak a ni 'King of Plastics' . Mahse, chemical inertness leh surface energy a tlem avangin PTFE hi thil dang nena inzawm a harsa a, hei hian a hmanna chu eng emaw chen a tikhawtlai a ni. PTFE leh thil chi hrang hrangte inzawmna tihchangtlun nan PTFE chunglam hnathawh tihpunna tur method hman a ni tlangpui. Product hrang hrang tan chuan Aokai New Materials hian a tlangpuiin a hnuaia PTFE surface modification methods te hi a hmang thin.

1. Wet Chemical hmanga enkawl dan

Sodium -naphthalene chemical treatment  hi PTFE surface modification atana hmanraw tangkai tak pakhat a ni. Process awlsam leh man tlawm tak a nih avangin Aokai New Materials’ PTFE factory-a practical production-ah chuan duhthlanna duh ber a ni.

Sodium-naphthalene treatment hian etching solution hmangin PTFE nen chemical reaction an nei tlangpui a, a chung atanga fluorine atom thenkhat an paih chhuak thin. Hei hian carbonized layer a hnutchhiah a, polar group hydroxyl group, carbonyl group leh unsaturated bonds te a rawn luh tir a ni. Heng polar group te hian polymer surface energy a tipung a, contact angle a ti tlem a, wettability a ti tha a, chu chuan PTFE chu non-bondable atanga bondable ah a chantir a ni.

2. Mechanochemical hmanga inzawmna siam dan

Polymer te hi pawn lam thiltihtheihna (eg, crushing, grinding, friction, etc.) hnuaia an awm chuan macromolecular chain te chu a chhe a, chemical reaction an nei a, chung zingah chuan mechanodegradation, mechanochemical crosslinking, mechanochemical grafting, block copolymerization leh stress-activated polymerization te pawh a tel a ni. Chungte chu polymer mechanochemical reaction tia hriat a ni.

Mechanochemical bonding-ah chuan adhesive-a khuh polymer chunglam chu an hnawih thin. Mechanochemical action hmangin polymer surface chu mechanodegradation a paltlang a, macromolecular free radicals a siam a, chu chuan adhesive molecule te nen covalent bonds a siam a, bonding interface nghet tak a siam a, joint bonding strength nasa takin a ti tha zawk a ni.

3. Temperature sang takah a hmin dan

High-temperature melting hmanga PTFE surface siam danglam dan bulpui ber chu: temperature sang takah chuan PTFE surface crystalline morphology a danglam a, high-surface-energy, awlsam taka inzawm thei material SiO2 leh Al powder te chu embedded a ni. A lum hnuah PTFE chung lamah hian bondable substance awmna modified layer a lo piang a. Bondable materials molecule te chu PTFE surface molecular layer ah an lut tawh avangin bond tihchhiat nan intermolecular destruction a ngai a, chu chuan bonding strength sang tak a siam a ni.

4. Radiation hmanga thil tih dan

PTFE hi reactive polymerizable monomers styrene, fumaric acid, methacrylates leh a dangteah dah a ni a, chutah chuan Co-60 hmangin irradiated a ni . Hei hian PTFE chung lamah monomers te chu chemical graft polymerization a tichhuak a, graft polymer layer a siam a, chu chu bond awlsam tak a ni. Grafting hian a chunglam a ti rough bawk a, bonding area a tipung a, bonding strength a ti sang bawk.

5. Plasma enkawl dan thiamna

Plasma treatment hi tun hnaia PTFE surface modification atana technology hmasawn chak ber pawl a ni.

He technology bulpui ber chu sample chu plasma treatment device bik-ah dah a ni a, chutah chuan ion bombardment emaw implantation emaw chuan molecular bonds a titawp emaw, polymer surface-ah functional groups a luhtir emaw a, chu chuan surface chu activate-in modification a thlen thei a ni. Ion hi inert gas, chemical active gas emaw metallic element emaw a ni thei. Inert gas hmanga bombardment hian polymer surface structure a tidanglam thei a ni.
