1. Isilinganiso sokucindezela sesikulufu esisodwa se-extruder sifanelekile phakathi kuka-1:2-1:3, okungcono kube ngu-1:2.5, kanti isilinganiso esifanele sobude nobubanzi besikulufu esinezigaba ezintathu singama-25. Umklamo omuhle wesikulufu ungagwema ukubola kwezinto nokuqhekeka okubangelwa ukungqubuzana okukhulu. Uma ubude besikulufu bungu-L, isigaba sokudla singama-0.3L, isigaba sokucindezela singama-0.4L, isigaba sokulinganisa singama-0.3L, kanti isikhala esiphakathi komgqomo wesikulufu nesikulufu singama-0.1-0.2mm. Ipuleti lezinyosi ekhanda lomshini kudingeka libe nezimbobo ezingu-1.5-5mm, kusetshenziswa izihlungi ezimbili ezingama-400 hole/cmsq (cishe ama-mesh angu-50). Lapho ukhipha amabhande amahlombe asobala, imoto enamandla amakhulu ngokuvamile iyadingeka ukuvimbela imoto ukuthi ingami noma ishe ngenxa yokugcwala ngokweqile. Ngokuvamile, izikulufu ze-PVC noma ze-BM ziyatholakala, kodwa izikulufu ezimfushane zesigaba sokucindezela azifaneleki.
2. Izinga lokushisa lokubumba lincike ezintweni ezisetshenziswa abakhiqizi abahlukene, futhi uma ubulukhuni buphakeme, izinga lokushisa lokukhipha liyanda. Izinga lokushisa lokucubungula likhuphuka ngo-10-20 ℃ kusukela esigabeni sokudla kuya esigabeni sokulinganisa.
3. Uma ijubane lesikulufu lishesha kakhulu futhi ukungqubuzana kushiswa kakhulu ngenxa yokucindezeleka okuncishisiwe, ukusethwa kwejubane kufanele kulawulwe phakathi kuka-12-60rpm, futhi inani elithile lincike kububanzi besikulufu. Uma ububanzi bukhulu, ijubane lihamba kancane. Izinto ngazinye zihlukile futhi kufanele kunakwe izidingo zobuchwepheshe zomhlinzeki.
4. Ngaphambi kokusebenzisa, isikulufu sidinga ukuhlanzwa kahle, futhi i-PP noma i-HDPE ingasetshenziswa ekuhlanzeni emazingeni okushisa aphezulu. Izinto zokuhlanza zingasetshenziswa nasekuhlanzeni.
5. Umklamo wekhanda lomshini kufanele uhambisane kahle futhi akufanele kube namakhona afile ukuqinisekisa ukugeleza kwezinto ezibushelelezi. Umugqa wokuthwala wesikhafu sesikhunta ungandiswa ngokufanele, futhi i-engeli phakathi kwezikhafu zesikhunta iklanyelwe ukuba phakathi kuka-8-12 °, okufaneleka kakhulu ukunciphisa ukucindezeleka kokusika, ukuvimbela ukuvuza kwamehlo ngesikhathi senqubo yokukhiqiza, kanye nokuqinisa inani lokukhipha.
6. I-TPU ine-coefficient ephezulu yokungqubuzana futhi kunzima ukuyibumba. Ubude bethangi lamanzi okupholisa kufanele bube bude kunezinye izinto ze-thermoplastic, kanti i-TPU enobunzima obuphezulu kulula ukuyibumba.
7. Ucingo oluyinhloko kumele lome futhi lungabi namabala kawoyela ukuvimbela ukuthi amabhamuza angenzeki ngenxa yokushisa. Futhi kuqinisekiswe ukuthi inhlanganisela engcono kakhulu.
8. I-TPU iyingxenye yezinto zokwakha ezithambile kalula, ezimunca umswakama ngokushesha uma zibekwe emoyeni, ikakhulukazi lapho izinto ezisekelwe ku-ether zithambile kakhulu kunezinto ezisekelwe ku-polyester. Ngakho-ke, kubalulekile ukuqinisekisa isimo esihle sokuvala. Izinto zithandwa kakhulu ukumuncwa komswakama ngaphansi kwezimo ezishisayo, ngakho-ke izinto ezisele kufanele zivalwe ngokushesha ngemva kokupakisha. Lawula okuqukethwe komswakama okungaphansi kuka-0.02% ngesikhathi sokucubungula.
