PTFE Tape-a Cooling Rate nghawng dan

PTFE high-temperature tape siamtu original a nih angin Jiangsu Aokai New Materials chuan cooling method leh cooling rates te hian cured PTFE high-temperature tape te performance a nghawng dan a sawifiah a ni.

I. PTFE Crystallization Characteristics leh Cooling Rate Regulation chungchang thupui ber

Cured high-temperature tape-a PTFE substrate hi semi-crystalline polymer a ni a, sintering hnua a lum laiin crystallization rang tak a tawk thin. A bul berah chuan cooling rate hi PTFE high-temperature tape crystallinity control nana core process parameter a ni: cooling slow zawk chuan crystallinity sang zawk a thlen a, cooling chak zawk chuan crystallinity a ti hniam thung.

II. PTFE High-temperature Tape-a Slow Cooling-in nghawng a neih dan

Internal Stress-a nghawng  Slow cooling hian tape chhunga residual thermal stress awm chu a ti tlem thei hle. Furnace chhunga tape chu natural taka a lum chuan PTFE matrix leh glass fiber skeleton te hian molecular chain relaxation hmanga shrinkage danglamna siamrem turin hun an nei tling a, local stress concentration a awm lo.

Mi tam takin an hman dan chu tape chu boruak lumna atana lak chhuah hmain furnace-ah natural takin 150–200°C thlenga tihlum hmasak a ni. Hetianga slow cooling process hian internal stress a ti tlem tha hle a, coating delamination leh cracking a veng bawk.

Dimensional Stability a nghawng dan  Slow cooling hian dimensional stability nasa takin a ti tha a ni. Slow cooling lai hian PTFE molecular chain te chu regular crystal lattice-ah a inrem tawk a, crystallinity sang tak leh crystal grain tha tak tak a siam a, hei hian final dimensions nghet tak a siam a ni.

A hman tak takah chuan temperature sang hnuaiah thermal shrinkage tlem a awm dawn a, chuvangin hman laiin 1%–2% margin reserve a tha. Slow cooling hian steady shrinkage a siam thei a, residual deformation tlem ber a awm bawk.

Adhesive Performance-a nghawng  Slow cooling hian adhesion property-ah nghawng pahnih a nei a. Khawthlang lamah chuan adhesive layer chu cross-linking leh stress relaxation chu a ti famkim thei a, bonding strength nghet tak a vawng reng a ni. A lehlamah chuan crystallinity sang zawk hian PTFE substrate surface rigidity a tisang a, chu chuan peeling force hnuaiah bonding interface-ah concentrated stress a siam a ni.

III. PTFE High-temperature Tape-a Rapid Cooling-in nghawng a neih dan

     Internal Stress-a Influence  Rapid cooling hi internal stress tam lutuk chhan ber a ni. Sintering hnua direct quenching hian PTFE matrix leh glass fiber framework inkarah temperature danglamna nasa tak a siam a, instant shrinkage stress a siam a, awlsam takin fine crack a siam thei bawk.

Surface layer chu a tlahniam a, a khauh chak hle a, a chhung lam chu a zau zel laiin, thermal stress state of outer tension leh inner compression a siam a, chu chuan direct-in tape a ti chhe a ni.

Dimensional Stability-a nghawng  Rapid cooling hian crystallization peak chu temperature hniam zawkah a sawn a, crystal structure tling lo nen crystallinity a tihhniam bawk. Tape hi a quench hnuah pawh unbalanced frozen state-ah a awm reng a ni. Secondary crystallization leh post-shrinkage hi a hnu lama temperature inthlak danglamna hnuaiah a thleng thei a, chu chuan dimensional deviation zawi zawiin a thlen thei a ni.

Adhesive Performance-a nghawng a neih  Fast cooling hian adhesive layer-te cross-linking kimchang a titawp a ni. Adhesive hi cross-linked network kimchang a siam hmain a frozen a, chu chuan bonding strength leh temperature resistance a tihhniam phah a ni.

Cold leh hot cycling repeated hnuaiah PTFE substrate leh adhesive layer inkara thermal expansion danglamna hian interfacial stress a siam a, adhesive aging leh debonding a ti chak a, viscosity durability nasa takin a tichak lo bawk.

IV. Cooling Method hrang hrang tehkhin dan

 

A tlangpuiin, PTFE high-temperature tape-te post-curing treatment atana hmanraw bulpui ber chu slow leh uniform cooling hi a ni. Sintering hnuah in-furnace natural cooling hman a tha a, 150–200°C hnuai lam a tlak hnuah air cooling atan tape te chu lakchhuah a tha. Production laiin cooling inang lo chuan slackness a siam ang a, a tawpah chuan product quality a tichhe ang.
