Teknologi Pengolahan Pipa Polivinil Klorida Klorida (PVC-C).

Ningbo Fangli Technology Co., Ltd.punikaprodusen peralatan mekanikkaro pengalaman saklawasé 30 taun 'sakaperalatan extrusion pipa plastik, pangayoman lingkungan anyar lan peralatan bahan anyar. Wiwit panyiapan Fangli wis dikembangake adhedhasar panjaluk pangguna. Liwat dandan terus-terusan, R&D independen babagan teknologi inti lan pencernaan & panyerepan teknologi canggih lan liya-liyane, kita wis ngembangakegaris ekstrusi pipa PVC, PP-R pipe extrusion line, Pasokan banyu PE / garis ekstrusi pipa gas, sing disaranake dening Kementerian Konstruksi Cina kanggo ngganti produk impor. Kita wis entuk gelar "Brand kelas kapisan ing Provinsi Zhejiang".

1,Extruder

Parallel utawa conical twin-screw extrudersbiasane digunakake kanggo extrude pipa CPVC. Ngelingi sing CPVC luwih gampang kanggo plasticize saka PVC, iku luwih gampang kanggo ngontrol produksi extrusion saka pipo CPVC kanthi nggunakakeparallel twin-screw extruders. Yen stabilizer uyah timbal digunakake ing rumus, extruder kudu kinerja plasticizing apik; Yen timah organik digunakake minangka stabilizer ing rumus, rasio komprèsi sekrup extruder ora bakal gedhe banget.

2. Teknik Pengolahan

Campuran bahan

The mixing process of CPVC resin is the same as that of PVC resin, which requires two processes: high-speed mixing and low-speed cooling mixing. Generally, the high-speed mixing temperature should be controlled at 115~125 ℃, not too high, otherwise it is easy to mix yellowing materials, causing material decomposition or "superplasticization" during extrusion. The temperature of low-speed cooling and stirring shall be controlled at 40~50 ℃ and shall not be too high, otherwise the mixed materials will absorb too much moisture in the air and affect the performance of the products due to the large difference between the mixed materials and the room temperature.

Suhu ekstrusi

Proses ekstrusi pipa CPVC fokus ing proses kasebutsuhu, kang langsung mengaruhi kualitas plasticizing pipo. Umumé, suhu proses bakal beda-beda amarga sifat plasticizing extruder sing beda, kadhangkala bedane 20 ~ 30 ℃. Secara teoritis, suhu pangolahan bahan CPVC luwih dhuwur tinimbang PVC, nanging nyatane, miturut pengalaman pangolahan taun, suhu pangolahan CPVC yaiku 5 ~ 8 ℃ luwih murah tinimbang PVC. Iki amarga viskositas leleh CPVC luwih dhuwur tinimbang PVC, lan akeh panas gesekan bakal diasilake antarane molekul molten. Ing wektu iki, yen extruder nyedhiyakake panas banget, gampang nyebabake dekomposisi materi.

Ing setelan suhu proses, kurva kudu katahan minangka Gamelan sabisa, kang ono gunane kanggo kualitas plasticization resin CPVC, lan kurva munggah lan mudhun ora kondusif kanggo plasticization saka pipe.

The whole process temperature control can be roughly divided into three parts: barrel, combiner core and mold. The barrel temperature decreases from Zone 1, and the combiner core temperature is slightly lower than the barrel temperature. In the mold temperature setting, it is worth noting the temperature of the die and the core mold. The temperature of the die should be about 10 ℃ lower than the temperature of the heating section of the barrel, otherwise the longitudinal shrinkage of the pipe will be affected, The pipes with no requirements for longitudinal shrinkage rate are not subject to this restriction. The heating of the core mold can be disconnected after the pipes are pulled out normally. The heat of the CPVC melt and the heat generated by the friction of the core mold can completely maintain the temperature of the core mold.
