1. Umlinganiselo wokunyanzeliswa kwesikrufu esinye se-screw extruder sifanelekile phakathi kwe-1: 2-1: 3, ngokukhethekileyo i-1: 2.5, kunye nobude obuphezulu ukuya kwi-diameter ratio ye-screw yezigaba ezithathu yi-25. Uyilo oluhle lokujikijela lunokuphepha izinto. ukubola nokuqhekeka okubangelwa kukukhuhlana okukhulu.Ukucinga ukuba ubude be-screw ngu-L, icandelo lokutya li-0.3L, icandelo loxinzelelo ngu-0.4L, icandelo lokulinganisa i-0.3L, kunye ne-gap phakathi kwe-screw barrel kunye ne-screw yi-0.1-0.2mm.I-honeycomb plate entloko yomatshini kufuneka ibe nemingxuma eyi-1.5-5mm, isebenzisa izihlungi ezimbini ze-400 / cmsq (malunga ne-50 mesh).Xa ukhupha imitya yegxalaba ecacileyo, i-motor yamandla aphezulu ehashe iyafuneka ngokubanzi ukunqanda i-motor ukuba ingazinzi okanye itshise ngenxa yokugcwala.Ngokubanzi, izikrufu ze-PVC okanye ze-BM ziyafumaneka, kodwa izikrufu zecandelo loxinzelelo olufutshane azifanelekanga.
2. Iqondo lokushisa lokubumba lixhomekeke kwizinto zabakhiqizi abahlukeneyo, kwaye ukuphakama kobunzima, ukuphakama kweqondo lokushisa eliphezulu.Ubushushu bokusebenza bonyuka nge-10-20 ℃ ukusuka kwicandelo lokutyisa ukuya kwicandelo lokulinganisa.
3. Ukuba isantya se-screw sikhawuleza kakhulu kwaye i-friction igqithise kakhulu ngenxa yoxinzelelo lwe-shear, ukumiswa kwesantya kufuneka kulawulwe phakathi kwe-12-60rpm, kwaye ixabiso elithile lixhomekeke kwi-screw diameter.Ubukhulu bedayamitha, isantya siyacotha.Isixhobo ngasinye sahlukile kwaye ingqalelo kufuneka ihlawulwe kwiimfuno zobugcisa zomthengisi.
4. Ngaphambi kokusetyenziswa, i-screw idinga ukucocwa ngokucokisekileyo, kwaye i-PP okanye i-HDPE ingasetyenziselwa ukucoca kumaqondo aphezulu aphezulu.Iiarhente zokucoca zingasetyenziselwa ukucoca.
5. Uyilo lwentloko yomatshini kufuneka lulungelelaniswe kwaye kungabikho iikona ezifileyo ukuze kuqinisekiswe ukuhamba kakuhle kwezinto.Umgca wokuthwala we-sleeve yokubumba unokwandiswa ngokufanelekileyo, kwaye i-angle phakathi kwemikhono yokubumba yenzelwe ukuba ibe phakathi kwe-8-12 °, efanelekileyo kakhulu ukunciphisa uxinzelelo lwe-chear, ukukhusela ukuchithwa kwamehlo ngexesha lenkqubo yokuvelisa, kunye nokuzinzisa i-extrusion. isixa.
6. I-TPU ine-coefficient ephezulu ye-friction kwaye kunzima ukuyilolonga.Ubude betanki lamanzi okupholisa kufuneka lube lude kunezinye izinto ze-thermoplastic, kwaye i-TPU enobunzima obuphezulu kulula ukwenza.
7. I-core wire kufuneka yome kwaye ingabi namabala e-oyile ukuthintela amaqamza ukuba angenzeki ngenxa yobushushu.Kwaye uqinisekise indibaniselwano engcono.
8. I-TPU yeyoluhlu lwezinto ezilula ze-hygroscopic, ezithatha ngokukhawuleza ukufuma xa zibekwe emoyeni, ngakumbi xa izinto ezisekelwe kwi-ether ziyi-hygroscopic ngaphezu kwezinto ezisekelwe kwi-polyester.Ngoko ke, kuyimfuneko ukuqinisekisa imeko efanelekileyo yokutywinwa.Izinto eziphathekayo ziyakwazi ukufunxa umswakama phantsi kweemeko ezishushu, ngoko ke izinto eziseleyo kufuneka zivalwe ngokukhawuleza emva kokupakishwa.Lawula ukufuma okungaphantsi kwe-0.02% ngexesha lokulungiswa.
