Sɛnea Anim a Wɔatwa no Awiei no Ma Adhesive Oozing

Adhesive oozing kyerɛ sɛ adhesive a ɛtwetwe fi teyp no ano a wɔanhyɛ da, ɛde efĩ ba adwumayɛ nneɛma a wɔakyekyere anaa teyp no akyi fã. Anim a wɔatwa no awiei no nya nkɛntɛnso tẽẽ.

1. Twe ne nhama tumi fi nea wɔatwa no mu

Sɛ slitting blade no yɛ dull anaasɛ twitting angle no mfata a, blade no bɛtwe na atrɛw silicone PSA a ɛyɛ mmerɛw no mu sen sɛ ebetwitwa no yiye. Eyi ma:

• Glue nhama ne burrs a wɔde hwɛ nneɛma nketenkete: Ntama a atetew no ma gluu nhama anaa nhama a ɛyɛ fɛ yiye a ɛpuepue fi teyp no ano. Saa 'glue whiskers' yi yɛ mmerɛw sɛ ɛbɛdannan na abubu bere a wɔreyɛ adwuma anaasɛ wɔrekora so no, na ɛma wonya nkɛntɛnso a wɔde hwɛ ade a ɛyɛ adhesive oozing.

• Adhesive migration towards: Tumi a ɛtwetwe bere a wɔrepaapae mu no twetwe adhesive kɔ awiei anim ne mpo substrate no ntwemu.

Sɛnea Cut End Face no Ma Edge Lifting Ba

1. Thinned ano adhesive layer – mmerɛw bonding beae

2. Substrate burrs ne delamination – wedging nkɛntɛnso

Sɛ slitting ma delamination ba PTFE coating ne fiberglass ntam wɔ anoano a, mismatched thermal expansion rates ma emu nhyɛso ba wɔ ɔhyew akyi, tẽẽ peeling anoano fi substrates.

3. Serrated anaa notched anoano – adwennwen dodow

4. Efĩ a efi extruded adhesive mu – wɔatew edge tack so
