isicelo

Inqubo yokukhiqiza hose ye-PVC:

Ukuxuba → ukuxova → i-extrusion granulation → ukwakheka kwe-extrusion → ukudonsa → ukugoqa → ukupakisha → ukuhlolwa kwekhwalithi → umkhiqizo oqediwe

1. Ukuxova izithako

Zonke izinhlobo zezinto zokusetshenziswa zikalwa ngokunembile futhi zifakwa ku-kneader ngokulandelana okuthile.Ukulandelana kokuphakelayo: PVC resin, plasticizer, stabilizer, lubricant.Lapho izinga lokushisa lifinyelela ku-100 ~ 110 ℃, impahla ingakhishwa.

2.i-extrusion granulation

Le nqubo yokulawula izinga lokushisa, indawo ephakeme kakhulu yokushisa yezinto ezibonakalayo kufanele ilawulwe ngaphezu kwezinga lokushisa elincibilikayo lezinto, liphansi kune-extrusion ekubumbeni izinga lokushisa, okungukuthi, phakathi kuka-155 ~ 160 ℃.I-granulation kufanele ifinyelele inhloso yokuxuba okugcwele kanye ne-plasticization yokuqala.

Izinga lokushisa lendawo ngayinye ye-granulator limi kanje:

Indawo engu-80 ~ 90 ℃;Indawo engu-130 ~ 140 ℃;Izindawo ezintathu 140 ~ 150 ℃;Kusukela ku-150 ~ 160 ℃.

3. Ukwakhiwa kwe-extrusion tube

Izinga lokushisa lokwakhiwa kwe-extrusion tube liphakeme kancane.Ngokuvamile, ukucaca kwepayipi kuhlobene nokushisa okwenza.Ezingeni elithile lokushisa, izinga lokushisa eliphezulu obala lihle, futhi ngokuphambene nalokho.Ngesikhathi esifanayo, isivinini sokudonsa kanye nesivinini sokupholisa sizothinta ukubonakala kwepayipi.Ijubane lokudonsa likhudlwana, isivinini sokupholisa siyashesha, futhi ukubonakala kwepayipi kungcono.Isivinini sokudonsa ngokuvamile sishesha ngo-10% ~ 15% kunejubane le-extrusion.Ukupholisa kwepayipi elikhanyayo kufafazwa ngamanzi abandayo lapho kufa ikhala bese kupholiswa ethangini lamanzi.

Izinga lokushisa lendawo ngayinye yokubunjwa kwe-extrusion limi kanje:

Indawo 1:90 ℃;Indawo yesibili 140 degrees 5 ℃;Izindawo ezintathu 160 degrees 5 ℃;Izindawo ezine 170 degrees 5 ℃.

4. Izinyathelo zokuqapha ze-PVC hose extrusion:

1. ngokuqondile ngokubunjwa kwe-powder extrusion, izinga lokushisa le-extruder licishe libe ngu-5℃ eliphansi kunelezinto eziyimbudumbudu.

2. Ngaphezu kobubanzi obuncane (φ60mm ngezansi) beshubhu lokupholisa elingenalutho akudingi ukushaywa emoyeni ocindezelwe, ububanzi obukhulu beshubhu lokupholisa elingenalutho kufanele bufuthelwe emoyeni ocindezelwe weshubhu, ukuze kuqinisekiswe ukuthi ukunemba nokuzinza kosayizi we-tube diameter.Naka ukucindezela okuzinzile komoya ocindezelweyo.

3. Naka ukuzinza kwesivinini sokudonsa futhi ugweme ukushintsha kobubanzi bepayipi noma ukushuba kodonga okubangelwa ukungazinzi kokudonsa.

4. Uma umshini uvaliwe isikhathi eside, kufanele uhlakazwe futhi uhlanzwe ukuze ugweme izinkinga zokubola.
