Rolled PTFE Tape chu Hun rei tak chhunga dahkhawmnaah a innghahna tur tihtawp dan

I roll a hawng a PTFE high-temperature tape . Thla tam tak chhung storage-a thut tawh Unwind i tum chuan layer te chu a inzawm khawm a. An phelh chuan non-stick back side-ah adhesive residue a awm a – tape chu a chhe vek.

He harsatna hi interlayer adhesion emaw blocking emaw an ti a . Thil pahnih avanga thleng a ni: PTFE leh silicone adhesive awm dan te, chubakah a dahna hmun tha lo vang te. Thu lawmawm tak chu a ven theih a ni – tape siam dan leh a dah dan atang pawhin.

Aokai PTFE hian uluk taka process control hmangin he harsatna hi a chinfel sak a ni. He guide hian blocking a awm chhan leh a pumpelh theih nan eng nge i tih theih tih a sawifiah a ni.

Engvangin Nge PTFE hian Tape A Block? Root Cause pahnih

Blocking ven nan chuan a thlentu mechanism pahnih i hriatthiam a ngai a ni.

1. Material property – PTFE memory leh adhesive creep te

• PTFE film elastic memory: A siam chhuah lai hian PTFE molecular chain te chu an inzawm khawm thin. Tape chu nghet taka hrual a, thla tam tak pressure hnuaia dah a nih chuan internal stress chu zawi zawiin a chhuak thin. Film hian a hnungtawlh tum a, chu chuan tape chu a warp emaw, adhesive chu a inthen emaw a ni.

• Silicone PSA creep: Silicone pressure-sensitive adhesive hi solid a ni lo – semi-fluid viscoelastic material a ni. Sustained pressure leh heat hnuaiah chuan microscope hmangin a luang (creeps) a, non-stick back side pores emaw texture emaw ah a lut a ni. Chutiang a nih chuan layer te chu an bond nghet vek a ni.

2. Pawn lama dahna tur hmun – lumna, lumna, leh pressure

• Temperature 40°C aia sang: Khua lum hian adhesive creep chu nasa takin a ti chak a. PSA viscosity a tlahniam a, flow a sang bawk.

• High humidity (>70% RH): Moisture hian adhesive chu hydrolysis a thlen thei a, a chunglam chu a tacky a, adhesion a tichak thei bawk.

• Stacking atanga mechanical pressure: Roll rit tak tak, a chunga stacked te chuan adhesive layer chu a hnuaia layer hnunglam ah an squeeze a, physical bonding a ti tlat thin.

A siam chhuahna tur solution – Gradient Winding Tension

Blocking venna atana pawimawh ber pakhat chu tape siam chhuah laiin engtin nge a hliam tih hi a ni.

1. Principle – pawn lam tight, chhung lam loose

Roll pakhat chu a chhung zawnga tension sang reng reng nena inzawm a nih chuan a chhung lam layer (core bulah) te chu sustained compressive stress hnuaiah an awm a ni. Thla tam tak a dah hnuah chuan chu stress chuan adhesive chu a hnunglam lamah a nawr lut ta a ni.

nen chuan Gradient winding tension :

• Pawn lam layer: hliam nghet tak (roll compact reng tur) .

• Inner layers: hliam chu a lo zau deuh deuh (core-a residual pressure tih tlem nan) .

Result: core hian sustained pressure a tawk lo tluk a, chuvangin adhesive creep chu a bo vek tawh.

2. A tih dan – closed-loop tension control

Aokai PTFE hian closed-loop tension control system a hmang a:

• Sensor te hian real-time roll diameter chu an enfiah thin

• Controller hian proprietary formula hmangin tension mamawh chu a chhut chhuak thin

• Actuators (variable-frequency emaw torque motor) te hian roll a lo san chhoh zel angin tension chu dynamically in an siamrem thin

Winding tension chu inner ring atanga outer ring thlengin a tlahniam zauh zauh thin. Hei hian a veng bawk . tight-set rolls (a chhung lam layer te chu a compress em em a, unwind harsa tak a nih chuan)

Additional Production Measures – Winding tih loh chu

Gradient tension hi a bulpui ber a ni a, mahse manufacturing step dang pawhin a pui bawk.

1. Thil hman tur dik tak thlang rawh

• High-cohesion silicone PSA: Pressure leh lumna hnuaiah a creep duh lo.

• Extruded PTFE film: Skived film aiin molecular orientation stress a nei tlem zawk a, elastic memory effects a ti tlem zawk.

2. A hnunglam lamah release coating hnawih rawh

Substrate non-adhesive lam chu fluorosilicone release coating emaw primer emaw hmangin enkawl rawh. Hei hian a hnunglam a surface energy a tihhniam a, adhesive chu a bond harsa hle.

3. Adhesive grade thick tak tak tan physical isolation dah belh tur

Tape adhesive layer thuk tak tak (>0.05mm) nei tan chuan release paper emaw release film emaw layer inkarah interleave rawh. Hei hi hun rei tak (thla 12 chhunga dah) atana fail-safe measure a ni.

Proper Storage – Lei Hnua I Mawhphurhna

Tape siam tha ber pawh hi a dah dik loh chuan a block thei. Heng dante hi zawm rawh.

1. Environment control – a lum leh vawt taka dah tur

2. Handling leh stacking – pressure na tak awm lo

• Roll te chu rack-ah horizontal (an sir lamah) dah rawh. An ding nghet ngai suh – hei hian edge deformation a thlen thei.

• Bulk stock atan chuan storage rack hmang rawh . Roll 3-4 aia sang stack suh – a hnuai lam roll te hian pressure nasa lutuk an tawk ang.

• Rotate rolls quarterly – stress-bearing position thlak danglam la, bottom rolls te chu chunglam lamah sawn rawh.

• Original packaging chu a awm reng ang – plastic wrap hian leivut leh boruak lum lakah a venghim. A chhiat chuan plastic film hmangin re-seal nghal tur a ni.

3. Roll awmsa, hlauhawma awm tawhte chu eng nge tih tur

Roll tha lo (hot, humid, stacked high)-a dah i neih chuan production-a i dah hmain sample tlemte test hmasa phawt ang che. Meter 1-2 vel unwind la, hetiang hian en rawh:

• Unwinding laiin dodalna danglam tak

• A hnunglam lamah adhesive residue a awm

• Roll core atanga hmuh theiha deformation

Chung zinga pakhat tal i hmuh chuan roll chu zawi zawiin (darkar engemaw zat 30-40°C chhung) lum la, i unwinding hmain – adhesive chu a nem tawk a, a fai thei ang. Mahse critical application atan chuan roll chu thlak leh rawh.
