Ukumelana nokushisa okuphezulu kwesikhumba se-PVC kuncike ezintweni ezifana nohlobo lwayo, izithasiselo, izinga lokushisa lokucubungula kanye nemvelo yokusebenzisa. .
Izinga lokushisa lokumelana nokushisa kwesikhumba esijwayelekile se-PVC licishe libe ngu-60-80 ℃. Lokhu kusho ukuthi, ngaphansi kwezimo ezijwayelekile, isikhumba se-PVC esivamile singasetshenziswa isikhathi eside kuma-degree angu-60 ngaphandle kwezinkinga ezisobala. Uma izinga lokushisa lidlula ama-degree angu-100, ukusetshenziswa kwesikhathi esifushane ngezikhathi ezithile kuyamukeleka, kodwa uma kusendaweni yokushisa enjalo isikhathi eside, ukusebenza kwesikhumba se-PVC kungase kuthinteke. .
Izinga lokushisa lokumelana nokushisa kwesikhumba se-PVC eliguquliwe lingafinyelela ku-100-130 ℃. Lolu hlobo lwesikhumba se-PVC ngokuvamile luthuthukiswa ngokungeza izithasiselo ezifana nezinzisi, izinto zokuthambisa kanye nezigcwalisi ukuze kuthuthukiswe ukumelana nokushisa. Lezi zengezo azikwazi nje ukuvimbela i-PVC ukuthi ingaboli emazingeni okushisa aphezulu, kodwa futhi inciphise i-viscosity encibilikayo, ithuthukise ukucutshungulwa, futhi ikhulise ubulukhuni nokumelana nokushisa ngesikhathi esifanayo. .
Ukumelana nokushisa okuphezulu kwesikhumba se-PVC nakho kuthinteka ekushiseni kokucubungula kanye nemvelo yokusetshenziswa. Ukuphakama kwezinga lokushisa lokucubungula, kuyancipha ukumelana nokushisa kwe-PVC. Uma isikhumba se-PVC sisetshenziswa isikhathi eside endaweni yokushisa ephezulu, ukumelana nokushisa kwayo kuzokwehla. .
Kafushane, ukumelana nokushisa okuphezulu kwesikhumba esijwayelekile se-PVC kuphakathi kuka-60-80 ℃, kuyilapho ukumelana nokushisa okuphezulu kwesikhumba se-PVC esiguquliwe kungafinyelela ku-100-130 ℃. Uma usebenzisa isikhumba se-PVC, kufanele unake ukumelana nokushisa okuphezulu, ugweme ukusisebenzisa endaweni yokushisa ephezulu, futhi unake ukulawula izinga lokushisa lokucubungula ukuze unwebe impilo yayo yesevisi. .
