Ndi chitukuko chosalekeza chazachuma komanso kupita patsogolo kosalekeza kwa anthu, zapereka chuma chambiri chogula, ndikupanga mikhalidwe yabwino yopititsira patsogolo moyo wa anthu ndikutsata moyo wamunthu, potero kufulumizitsa kufunikira kwa zinthu zogula, ndi TPU. Zogulitsa ndi imodzi mwazo, ndiye zomwe ziyenera kutsatiridwa ndi chiyani mukamaumba jakisoni wa TPU?Kenako, tidzafotokoza mwatsatanetsatane.
1. Kuthamanga kwa jekeseni ndi malo a kutembenuka kwamphamvu ziyenera kukhazikitsidwa molondola.Kuyika malo olakwika kudzawonjezera kuvutikira kwa kusanthula kwa chifukwa, komwe sikungathandize kuwongolera mwachangu komanso molondola.
2. Pamene chinyezi cha TPU chikupitirira 0.2%, sichidzangokhudza maonekedwe a mankhwala, komanso makina opangidwa ndi makina adzawonongeka mwachiwonekere, ndipo mankhwala opangidwa ndi jekeseni adzakhala ndi mphamvu zochepa komanso mphamvu zochepa.Choncho, ziyenera kuumitsidwa pa kutentha kwa 80 ° C mpaka 110 ° C kwa maola 2 mpaka 3 musanayambe kuumba jekeseni.
3. Kuwongolera kutentha kwa kutentha kumakhudza kwambiri kukula, mawonekedwe ndi mawonekedwe a chinthucho.Kutentha kwa processing kumadalira kalasi ya TPU ndi zochitika zenizeni za mapangidwe a nkhungu.Zomwe zimachitika ndikuti kuti mupeze kuchepa pang'ono, ndikofunikira kuwonjezera kutentha kwa processing.
4. Kuthamanga kwapang'onopang'ono komanso kwanthawi yayitali kudzatsogolera kumayendedwe a maselo.Ngakhale kuti n'zotheka kupeza kukula kwazinthu zazing'ono, kusinthika kwa mankhwala ndi kwakukulu, ndipo kusiyana pakati pa shrinkage yopingasa ndi yaitali ndi yaikulu.Kuthamanga kwakukulu kumapangitsanso kuti colloid ikhale yoponderezedwa kwambiri mu nkhungu, ndipo kukula kwa mankhwala pambuyo pobowola ndi kwakukulu kuposa kukula kwa nkhungu.
5. Chisankho cha makina opangira jekeseni chiyenera kukhala choyenera.Kakulidwe kakang'onojekeseni akamaumba mankhwalaayenera kusankhidwa ngati makina ang'onoang'ono opangira jekeseni momwe angathere, kuti awonjezere jekeseni wa jekeseni, atsogolere kulamulira malo, ndikusintha moyenera jekeseni liwiro ndi kupanikizika.
6. Mtsuko wa makina opangira jekeseni uyenera kutsukidwa, ndipo kusakaniza kwa zinthu zina zochepa kwambiri kumachepetsa mphamvu yamakina a mankhwala.Migolo yotsukidwa ndi ABS, PMMA ndi PE iyenera kutsukidwanso ndi zinthu za TPU za nozzle musanabayidwe kuti muchotse zinthu zotsalira mu mbiya.Poyeretsa hopper, chisamaliro chapadera chiyenera kuperekedwa pakuyeretsa kwazinthu zochepa zopangira ndi zinthu zina mu gawo lolumikizana pakati pa hopper ndi maziko a makina opangira jekeseni.Gawoli limanyalanyazidwa mosavuta ndi ogwira ntchito zaluso kwambiri pakupanga.
