Raws li lub siab -}}}}} paab cov ntaub ntawv, thermoplastic polyurethane, kev noj qab haus huv.
TPU film is a thermoplastic polymer material made of polyols and diisocyanates. Its hardness range is 60HA-85HD. It has high elasticity (elongation at break>400%), hnav tsis kam, thiab kua muag tiv taus. Aliphaatic TPU muaj cov qauv zoo nkauj zoo dua thiab muaj cov ntawv qhia txog kev ua yeeb yaj kiab thiab muaj peev xwm tswj hwm kev ua yeeb yaj kiab.
Nws yog dav siv nyob rau hauv ntau cov khoom siv kho mob, suav nrog cov txheej txheem txheej txheem lossis cov leeg tshuaj, quav yeeb yam, thiab anti - Cov khoom lag luam. Nws cov lus teb qhib cia cov neeg ua haujlwm kho mob saib xyuas cov xwm txheej hauv cov hlab. Nws yog siv nyob rau hauv kev tsim cov gaskets thiab txuas rau lub ntsej muag ua pa thiab cov kua mis oxygen, ua kom muaj cov ntsej muag zoo nkauj thiab xis nyob. Nws kuj ua raws li txheej tiv thaiv rau sensors, tiv thaiv kev cuam tshuam sab nraud thiab txhim kho cov khoom siv kev ntseeg tau.
TPU zaj duab xis yog siv dav hauv kev ntim khoom hauv kev siv tshuaj, khoom siv kho mob thiab cov khoom kho mob vim nws cov khoom siv kho mob vim nws cov khoom siv kho mob vim nws cov khoom siv kho mob vim nws cov khoom siv kho mob vim nws cov khoom siv kho kom zoo thiab pob tshab. Nws zoo siab tiv thaiv cov khoom lag luam los ntawm sab nraud ib puag ncig kev cuam tshuam, ua kom lawv huv thiab huv si, tswj cov khoom siv ntawm cov txheej txheem thiab cov ntawv sau meej.
Siv zaj duab xis TPU tseem tuaj yeem siv rau hauv cov khaub ncaws khomob TPU, xws li cov khaub ncaws tiv thaiv mob, los muab cov hnab looj tes kho mob ntxiv vim nws cov pa hluav taws xob zoo nkauj, dej tsis kam thiab biocompatibility. Nws yog siv los ua ntau yam tshuaj kho mob, xws li cov khoom siv kho mob xws li kev hnav khaub ncaws thiab hloov kho tau yooj yim, thiab tuaj yeem hloov cov hlau endotracheal leeg
TPU feem ntau yog hloov tau yooj yim thiab elastic tshaj 80 zaj duab xis thiab yog ib puag ncig phooj ywg, thaum pvc tsim cov teeb meem tsis zoo thaum tsim khoom thiab kev ua haujlwm. TPU tseem zoo dua li PVC ua cov nqe lus pob tshab thiab yog qhov tsim nyog rau cov ntawv thov kev kho mob nrog cov kev xav tau zoo.
Nrog nws cov kev ua yeeb yam zoo heev, TPU zaj duab xis tau dhau los ua cov khoom siv tsis tseem ceeb hauv cov tshuaj niaj hnub. Los ntawm cov khoom siv kho mob ib txwm siv rau cov khoom siv hluav taws xob tshiab rau kev ua kom siab rau cov khoom siv TPU zaj duab xis txuas ntxiv nthuav. Nrog kev nce qib hauv cov ntaub ntawv kev tshawb fawb thiab kev ua yeeb yam ntawm kev kho mob ib puag ncig, muab kev nyab xeeb txhim kho, muab cov kev daws teeb meem ib puag ncig, muab cov kev daws teeb meem ib puag ncig, thiab txhim kho} cov khoom siv kho mob rau kev lag luam kho mob. Daim ntawv thov tom ntej ntawm TPU zaj duab xis hauv kev txiav - ntug teb thiab cov khoom siv hauv cov tshuaj ntse yog qhov txaus siab tshwj xeeb.
