Bolehkah paip PVC dicairkan panas?

2025-08-19

Dalam pemasangan dan pembinaan saluran paip, pilihan kaedah sambungan secara langsung berkaitan dengan kualiti kejuruteraan dan kesan penggunaan kemudian. Ramai orang akan bertanya: Bolehkah paip PVC dicairkan panas? Sebagai salah satu paip plastik yang biasa digunakan, terdapat perbezaan antara kaedah sambungan paip PVC dan paip seperti PPR. Hari ini kita akan membincangkan isu ini secara terperinci dan memperkenalkan kaedah sambungan paip PVC yang betul untuk paip AD.

Pertama sekali, perlu dijelaskan bahawa paip PVC (paip polivinil klorida) secara amnya tidak sesuai untuk sambungan cair panas. Kestabilan haba bahan PVC agak lemah dan mudah terurai pada suhu tinggi yang diperlukan untuk cair panas. Ia bukan sahaja akan menjejaskan sifat fizikal paip, mengakibatkan penurunan kekuatan tapak sambungan, tetapi juga mungkin membebaskan bahan berbahaya, menjejaskan keselamatan pembinaan dan perlindungan alam sekitar. Oleh itu, sambungan cair panas bukanlah kaedah sambungan arus perdana untuk paip PVC. Penggunaan membuta tuli boleh meninggalkan bahaya tersembunyi seperti kebocoran air dan paip pecah.

Jadi, apakah kaedah sambungan yang betul untuk paip PVC? Pada masa ini, pelekat gam adalah yang paling banyak digunakan. Kaedah ini mudah dikendalikan dan cekap, dan sesuai untuk kebanyakan paip saliran PVC dan sistem paip bekalan air. Semasa pembinaan, adalah perlu untuk membersihkan bahagian sambungan paip dan kelengkapan terlebih dahulu untuk memastikan tiada pencemaran minyak, habuk dan kelembapan, kemudian menggunakan gam paip PVC khas secara sama rata. Apabila gam sedikit volatilisasi, silah paip dengan cepat ke dalam kelengkapan paip dan kekalkan ikatan untuk satu tempoh masa sehingga ia kukuh. Sebagai pengeluar paip profesional, kelengkapan paip PVC telah mempertimbangkan sepenuhnya kebolehpercayaan sambungan dalam reka bentuk dan proses pengeluaran. Getah sokongan juga telah diuji dengan ketat untuk memastikan kesan lekatan yang berkesan.

Selain ikatan gam, untuk beberapa senario tertentu, sambungan bebibir atau sambungan soket gelang getah juga boleh digunakan. Sambungan bebibir sesuai untuk paip berkaliber besar atau tapak yang memerlukan pembongkaran kerap. Bebibir dan gelang pengedap diketatkan dengan bolt untuk mencapai sambungan pengedap; sambungan soket gelang getah bergantung pada pengedap elastik gelang getah. Biasanya digunakan dalam sistem saliran, ia mempunyai ciri pemasangan pantas dan pengedap yang baik. Tidak kira kaedah sambungan yang digunakan, adalah perlu untuk memastikan padanan spesifikasi kelengkapan paip dan beroperasi dengan ketat mengikut spesifikasi pembinaan. Paip

AD mengingatkan pengguna bahawa apabila memasang paip PVC, kaedah sambungan yang sesuai harus dipilih mengikut keperluan kejuruteraan sebenar, dan paip dan kelengkapan dan aksesori yang dihasilkan oleh pengilang biasa digunakan. Kaedah penyambungan yang betul bukan sahaja dapat memastikan pengedap dan ketahanan sistem paip, tetapi juga berkesan mengelakkan peningkatan kos penyelenggaraan kemudian. Jika terdapat keraguan tentang kaedah penyambungan, adalah disyorkan untuk berunding dengan juruteknik profesional atau merujuk manual produk untuk memastikan kualiti pembinaan memenuhi piawaian.

Ringkasnya, disebabkan oleh had sifat bahan, paip PVC tidak disyorkan untuk menggunakan sambungan cair panas, ikatan gam, sambungan bebibir dan kaedah lain adalah pilihan yang lebih dipercayai. Pilih jenama terkenal seperti saluran paip AD dan beroperasi dengan ketat mengikut spesifikasi pembinaan yang mereka sediakan, supaya sistem saluran paip PVC dapat memainkan prestasi yang stabil dalam penggunaan jangka panjang
