Paralel Oposit Rotting Twin Skru Ekstruda

Disain bilong rives twin-skru em i simpol tru. Bikos long tupela skru i tantanim long narapela rot na i gat liklik kontek poin namel long ol, ol stretpela mak bilong fit namel long ol skru i liklik tru. Insait long wanpela kauntating twin-skru ekstruda, ol samting bilong trenspot bilong ol samting i wankain olsem gutpela displesmen mod insait long wanpela gia pam. Karakteristik bilong dispela ekstruda em liklik rotesen spit bilong en, we i daunim hat i kamap long rot bilong shearing na daunim risk bilong ol samting i bagarap. Olsem na em i gat liklik mak bilong ol samting i stap long thermal stebiliti bilong ol samting na em i gutpela tru long wokim na prosesim ol samting bilong hatim hat olsem PVC.

Ol oposit rotesen twin skru ekstruda i gat bikpela wok bilong karim samting, gutpela eksos na melting ifek. Maski wok bilong en i go bikpela na i no gat planti samting long en i no gutpela tumas, em inap long kamapim gutpela presa bilong het, na dispela i mekim em i kamap gutpela samting bilong stretim ol samting. Antap long dispela, ol i ken rausim pre plastisaisesen granulesen proses na PVC paura i ken proses stret long daunim kos bilong prodak.
Long pasin bilong bipo, ol i save yusim moa yet ol anisotropik konikel twin-skru ekstruda bilong rausim ol samting bilong polivinil klorait (PVC). Tasol long ol yia i go pinis, sampela pasin bilong haus i soim olsem ol anisotropik konikel twin-skru ekstruda tu ol i ken yusim gut tu long rausim ol polyolefin (olsem polietilen, PE) paip. Bikpela tingting bilong yusim wanpela anisotropik konikel twin-skru ekstruda long rausim ol polyolefin paip em long sevim eneji na daunim kos.

Olsem, wanpela 65mm diamita konikel twin-skru ekstruda wantaim skru spesing bilong 132um i gat draiving mota pawa bilong 37kW tasol, taim wanpela 75mm o 80mm singel skru ekstruda i gat draiving pawa bilong no liklik long 90kW. Dispela i min olsem, long wankain o wankain autput, wanpela kaunta i tanim konikel twin-skru ekstruda i ken givim gutpela eneji efisiens.
It is worth noting that due to the significant differences in flow characteristics between polyolefin melt and polyvinyl chloride melt, when applying the originally designed anisotropic conical twin-screw extruder for PVC to polyolefin pipe extrusion, the screw design needs to be adjusted to ensure effective processing of polyolefin materials, and corresponding modifications may also be required to the extrusion die (head).

Dispela ko rotesen twin-skru ekstruda, bikos long ol pasin bilong en i stret tru na i gat bikpela teknoloji konten, ol i wokim wantaim bikpela stretpela na kompleksiti; Long sait bilong mentenens, ol i mas putim moa taim na hatwok long mekim wok long gutpela menesmen. Oposit daireksen twin-skru ekstruda i bin winim laik bilong sampela yusa wantaim klinpela na klia disain bilong en, moa yet long ol aplikesen senario we i bihainim stebiliti na reliabiliti .
Oposit roteting twin skru extruder em i wanpela spesel ikwipmen i gutpela long ekstrusen molding bilong ol kain kain PVC paura. Em i gat ol narapela narapela mol na ol masin bilong helpim wok, na em inap kamapim ol kain kain PVC plastik paip, profail, plet, pepa, bar na pelet.
