Ukuze uthole impahla okuhlala, acwebezelayo futhi engasindi, kuzomele wenze Foam PVC

PVC uhlobo ezivamile - ishidi kokuba isakhiwo ukungena nakwamanye amazwe ngenhloso ngaphandle okwe tint opaque. Uma foamed PVC, kungenzeka ukuthola isikhathi eside futhi zidabuke kanzima touch impahla nge surface bushelelezi ecwebezelayo kokuba isakhiwo zezinhlobo "isangweji". ungqimba wayo bangaphakathi ukungena nakwamanye amazwe, kodwa ngesikhathi esifanayo ukuthungwa uhlala homogenous.

Ukukhiqizwa PVC foam

ukuze umkhiqizo foamed PVC nesakhiwo yalo, usebenzisa zokukhiqiza imigqa ehlanganisa imishini efana extruder, a spinneret calibrators olufanele ezipholile, ukuthi idivaysi eyamukelayo kanye nedivaysi silungiselela umkhiqizo yokugcina. Naphezu kweqiniso lokuthi kule ukukhiqizwa eziyinkimbinkimbi ngokomzimba kanye nezinkomba zamakhemikhali, yonke inqubo ithatha indawo workshop ezincane, ihlanzekile futhi icocekile.

The main impahla eluhlaza ngesimo zithutha luyimbudumbudu futhi ingxube ilethwa izikhwama zepulasitiki. On the amapulatifomu encane lezimpahla efakwe amathangi insimbi engagqwali enyakaza-tank, lapho ligcwele, amanzi wanezela. iqala Ngakho inqubo lapho kutholakala foamed PVC. Ukukhiqizwa yayo ezibonakala silula. Abaneminyaka e nezikhamo zingakapheli izinsuku ingxenye polymeric iyaphendula ndawonye ukuvuthwa ifinyelela ukungaguquguquki kanye mass oncibilikisiwe is fed egumbini ethola i extruder eye qualitatively foamed PVC.

Kuye extruder isitshalo ukusebenza kungaba nesikulufu owodwa noma umsebenzi amabili. Ochwepheshe uncamela izitshalo nge ngezikulufo ezimbili. Bebuthana oncibilikisiwe kukhona ukugeleza okufanayo, inqobo nje uma izinga lokushisa alushintshi, okuvumela PVC foam ngokulinganayo futhi kwamandla sifinyelele kwabantu angadingeki umkhiqizo.

Augers ukudlulisela mass epulasitiki extrusion. Lapha (ngenxa overpressure) siphatha foamed PVC, bese ukumpintsha ngokusebenzisa izimbobo we extruder, enikeza yomkhiqizo shape. Kwakheka amaphrofayli, amashubhu, amashidi, amafilimu ufika etafuleni eyamukelayo, lapho fed ungene eshukumisayo ibhande futhi kanyekanye selehlile.

Cutting kanye ubuciko

Ukuze ukusika imikhiqizo PVC ukusebenzisa ezihluthulelwe isiyingi, ifakwe vacuum cleaner futhi iqoqo izinsalela. Ukuphuca imikhiqizo ekhiqizwa ngesivinini. Khona-ke ebusweni singasebenza nasekunakekelweni iphethini zokuhlobisa. Kuze kube yimanje, ukucutshungulwa uchungechunge zihlanganisa Greiner-mshini, ukuphrinta izithombe kanye wokugubha ngqo imikhiqizo PVC. enamathela okuhlobisa ungakwazi belingisa zemabula chips, usimende, babe nezinye izinhlobo ukucubungula.

Yini bubaluleke kakhulu futhi lapho esetshenziswa?

izimfanelo ezibalulekile kakhulu ezifana amandla, kalula isakhiwo esihle-ekubambisaneni futhi elinendawo PVC foamed. Photo isetshenziswa kulesi sihloko, ubonisa kubo ngesibonelo ipayipi. Esigabeni ngokucacile porosity ebonakalayo, futhi lokhu naphezu kweqiniso lokuthi ebusweni mkhiqizo acwebezelayo futhi abushelelezi.

Ukumelana izici zangaphandle zezulu, zamakhemikhali ekuxhumaneni ngokomzimba futhi ukugqwala wavuleka avule umnyango le nto ukusetshenziswa ekwakheni, ukukhangisa ibhizinisi, ezolimo, ezishisayo amandla isizukulwane, uwoyela negesi namakhemikhali umkhakha, ekhaya.
