PVCパイプの接着剤の塗り方

2025-08-19

PVCパイプを設置する場合、接着剤の正しい塗布は、しっかりとした接続と漏れのないシールを確保するための重要なリンクです。以下では、建設担当者が操作を標準化し、パイプラインシステムの安全性と耐久性を向上させるのに役立つ、ADパイプPVCパイプ接着剤の標準的な手順と注意事項について詳しく説明します。

1.準備作業

1.パイプ継手の検査

使用されているADパイプPVCパイプがパイプ継手の仕様と一致していることを確認し、ポートに亀裂やへこみなどの欠陥がないことを確認します。製品の寸法精度と材料の互換性を確保するために、ADパイプなどの有名なブランドの高品質のPVCパイプ継手を選択することをお勧めします。

2.表面洗浄処理

乾いた布またはサンドペーパーを使用して、パイプソケットの外側とパイプ継手の内側を徹底的切断後にパイプにバリがある場合は、シール効果に影響を与えないように、面取り器またはサンドペーパーを使用して滑らかに研磨する必要があります。

3.マーキング挿入深さ

鉛筆またはマーカーペンを使用して、パイプ挿入端の挿入深さラインをマークします。挿入深さは通常、パイプ継手の深さの2/3です。接続が正確に行われるようにします。

2.接着剤の選択と塗布の仕様

1。特殊接着剤の選択

は、ADパイプPVCパイプと一致する特殊なPVC-U接着剤を選択する必要があります。接着剤の製造日と貯蔵寿命を確認し、有効期間内に使用することを確認してください。接着剤を開ける前に、パッケージの状態を確認し、固化または劣化した製品の使用を避けてください。

2.接着剤の攪拌と塗布117277984最初にチューブソケットの内側を塗り、軸方向に沿って均一に塗り、表面の小さな凹凸を覆うことができる厚さの連続フィルムを形成します。次に、チューブソケットの外側を塗ります。塗りの長さは、接着剤が挿入後に隙間を完全に埋めることができるように、マークされた深さの線よりも5〜10 mm長くする必要があります。

3.塗布速度制御

接着剤が空気中に長時間さらされて結膜を引き起こさないように、塗布動作は一貫して迅速である必要があります。周囲温度が高い(30°Cを超える)場合は、接着剤が早期に硬化するのを防ぐために、塗布間隔を短くすることをお勧めします。

3.接続および硬化操作のポイント

1.クイックプラグの位置合わせ

接着が完了したら、すぐにチューブソケットをチューブソケットの中心に合わせ、軸接着剤が押し出されてシールに影響を与えないように、回転角度は90を超えないようにしてください。

2。固定およびオーバーフロー処理

を挿入した後、脱落を防ぐためにパイプとパイプ継手を30秒以上静止させます。接続部から少量の接着剤がこぼれた場合は、最初に固化した後、残留接着剤がパイプ表面を腐食しないように乾いた布で拭き取ってください。

3。硬化時間制御

建設環境温度が約20°Cの場合、硬化時間は30分以上にすることをお勧めします。低温環境(10°C未満)は1〜2時間に延長する必要があります。完全に硬化する前に、パイプの移動や圧力テストは禁止されています。具体的な硬化時間については、使用するADパイプ接着剤の製品説明を参照してください。

IV。安全性施工安全防護

操作時にはゴム手袋を着用し、施工現場の換気を良好に保ち、接着剤の揮発ガスが集まらないようにする必要があります。火元の近くで接着剤を使用することは厳禁で、保管時に密封して遮光して保存する必要があります。

2.よくある問題処理

接着剤を塗った後に差し込みが困難になった場合、塗布が厚すぎたり、管材の挿入角度がずれたりする可能性があります。すぐに抜いて表面を再洗浄し、接着剤を塗り直す必要があります。インターフェイスに漏れがある場合は、接着剤が完全に固化した後、インターフェイスを切除し、仕様に従って操作し直す必要があります。

上記の手順に従うことで、ADパイプPVC管の接続品質を効果的に向上させることが
