1. Isilinganiso sokuminyanisa sesikulufu esisodwa sesikulufu sifaneleka phakathi kuka-1:2-1:3, okungcono kakhulu ku-1:2.5, futhi isilinganiso sobude obuphelele ukuya kobubanzi besikulufu sezigaba ezintathu singu-25. Idizayini yesikulufu esihle ingagwema okubalulekile. ukubola nokuqhekeka okubangelwa ukungqubuzana okukhulu.Uma kucatshangwa ukuthi ubude besikulufa bungu-L, isigaba sokuphakelayo singu-0.3L, isigaba sokuminyanisa singu-0.4L, isigaba sokulinganisa singu-0.3L, futhi igebe phakathi kombhobho wesikulufu nesikulufu ngu-0.1-0.2mm.Ipuleti lekhekheba lezinyosi ekhanda lomshini lidinga ukuba nemigodi engu-1.5-5mm, lisebenzisa izihlungi ezimbili ezingama-400/cmsq (cishe ama-mesh angama-50).Lapho ukhipha amabhande ehlombe asobala, injini yamandla amahhashi ephakeme ngokuvamile iyadingeka ukuze kuvinjwe injini ukuthi ingami noma iphele ngenxa yokugcwala kakhulu.Ngokuvamile, izikulufu ze-PVC noma ze-BM ziyatholakala, kodwa izikulufu zesigaba sokucindezela okufushane azifaneleki.
2. Izinga lokushisa lokubumba lincike ezintweni zabakhiqizi abahlukene, futhi ukuphakama kokuqina, kuyanda ukushisa kwe-extrusion.Izinga lokushisa lokucubungula likhuphuka ngo-10-20 ℃ ukusuka esigabeni sokuphakela kuya esigabeni semitha.
3. Uma isivinini sesikulufu sishesha kakhulu futhi ukungqubuzana kushisa kakhulu ngenxa yengcindezi yokugunda, ukulungiselelwa kwesivinini kufanele kulawulwe phakathi kuka-12-60rpm, futhi inani elithile lincike kububanzi besikulufa.Uma ubukhulu be-diameter bukhulu, ijubane lihamba kancane.Impahla ngayinye ihlukile futhi kufanele kuqashelwe izidingo zobuchwepheshe zomphakeli.
4. Ngaphambi kokusetshenziswa, isikulufu sidinga ukuhlanzwa kahle, futhi i-PP noma i-HDPE ingasetshenziselwa ukuhlanza emazingeni okushisa aphezulu.Ama-agent okuhlanza angasetshenziswa futhi ekuhlanzeni.
5. Umklamo wekhanda lomshini kufanele uqondiswe futhi akufanele kube namakhona afile ukuze kuqinisekiswe ukugeleza kwezinto ezibushelelezi.Umugqa othwalayo womkhono wesikhunta unganwetshwa ngokufanelekile, futhi i-engeli phakathi kwemikhono yesikhunta iklanyelwe ukuba ibe phakathi kuka-8-12 °, ofaneleka kakhulu ukunciphisa ukucindezeleka kwe-shear, ukuvimbela ukudonsa kwamehlo ngesikhathi senqubo yokukhiqiza, nokuzinzisa i-extrusion. inani.
6. I-TPU ine-coefficient ephezulu yokungqubuzana futhi kunzima ukuyibumba.Ubude bethangi lamanzi okupholisa kufanele bube bude kunezinye izinto ze-thermoplastic, futhi i-TPU enobulukhuni obuphezulu kulula ukwakha.
7. Intambo ewumgogodla kufanele yome futhi ingabi namabala kawoyela ukuvimbela amabhamuza ukuthi angenzeki ngenxa yokushisa.Futhi uqinisekise inhlanganisela engcono kakhulu.
8. I-TPU ingeyesigaba sezinto ezisetshenziswa kalula yi-hygroscopic, ezimunca ngokushesha umswakama lapho zibekwe emoyeni, ikakhulukazi uma izinto ezisekelwe ku-ether zine-hygroscopic kunezinto ezisekelwe ku-polyester.Ngakho-ke, kuyadingeka ukuqinisekisa isimo esihle sokuvala uphawu.Izinto ezisetshenziswayo zijwayele ukumuncwa umswakama ngaphansi kwezimo ezishisayo, ngakho-ke izinto ezisele kufanele zivalwe ngokushesha ngemva kokupakishwa.Lawula umswakama ongaphansi kuka-0.02% ngesikhathi sokucubungula.
