Thermoplastics Nkag mus rau Cov Qauv Txheej Txheem Ua Lag Luam
Rau lub sijhawm ntev, honeycomb cores tau tswj hwm los ntawm ntawv, txhuas, thiab thermosets -raws li kev sib xyaw. Txhua yam ntawm cov ntaub ntawv no tau txais kev lag luam tshwj xeeb, tab sis tag nrho cov ntawm lawv muaj kev txwv thaum raug cov dej noo, rov cuam tshuam dua, cov kev xav tau rov ua dua tshiab, lossis cov kev xav tau sib sau ua ke.
Thermoplastic honeycomb cores tau nkag mus rau qhov chaw no nrog tus nqi sib txawv. Tsis txhob cia siab rau cov tshuaj tua kab mob thiab kev sib txuas tsis sib haum, lawv siv cov cua sov-formable polymers xws li PP, PET, PC, thiab hloov kho cov khoom sib xyaw. Qhov kev hloov no tsis yog tsuas yog xaiv cov khoom siv xwb; nws hloov kho li cas cov qauv kev ua haujlwm tau txhais, tsim, thiab siv.
Hauv kev thauj mus los, cov qauv txawb, cov khoom siv hauv tsev, thiab cov tshuab modular, cov thermoplastic honeycomb cores tsis tau pom dua li kev sim. Lawv tau teev nyob rau hauv tej yaam num uas qhov hnyav, qaug zog lub neej, noo noo tsis kam, thiab recyclability yog tag nrho cov kho raws li engineering xav tau es tsis xaiv yam ntxwv.
