PU CPU TPU yog dab tsi -2

Cov khoom siv CPU yog dab tsi?

Cov khoom siv CPU, tseem hu ua Casting PU Resin, suav nrog cov kua thermoset PU resin tab tom hla kev sib txuas tshuaj tiv thaiv thiab cua sov kom khov thiab zoo. Cov chemistry no ua rau muaj cov qauv molecular mesh uas muaj cov khoom zoo ntawm lub cev tab sis tsis tuaj yeem siv tau yooj yim los yog thim rov qab-tsim tom qab tsim. Casting PU resin feem ntau hu ua CPU hauv kev lag luam thiab yog siv los tsim cov khoom siv hluav taws xob zoo xws li cov menyuam, qhov chaw, squeegees, thiab cov log tsheb. Cov kua PU resin yog tov thiab muab pov rau hauv pwm thiab tso cai rau kho, ua rau qhov xav tau.

Cov khoom siv TPU yog dab tsi?

Thermoplastic PU (TPU) yog cov khoom siv hluav taws xob linear uas tuaj yeem ua tau zoo li siv ntau hom qauv yas molding xws li kev txhaj tshuaj molding thiab extrusion. TPU muaj lub sijhawm ua haujlwm luv dua thiab ua haujlwm zoo dua li CPU, thiab cov khoom kawg tuaj yeem siv tau yooj yim thiab rov ua dua. TPU feem ntau yog siv los tsim cov khoom lag luam nrog cov kev xav tau siab, xws li khau kis las, cov yeeb yaj kiab ua haujlwm, hoses, thiab cov hlua sib kis. TPU tuaj yeem tsim tau ntau yam duab thiab qhov ntau thiab tsawg raws li qhov xav tau sib txawv.

Zuag qhia tag nrho, CPU thiab TPU yog ob qho tib si polyurethane (PU) cov ntaub ntawv uas tuaj yeem tsim cov khoom nrog cov yam ntxwv sib txawv nyob ntawm txoj kev ua thiab cov xwm txheej. PU feem ntau muaj elasticity zoo thiab hnav tsis kam, CPU elastomer muaj zog dua lub cev, thiab TPU elastomer yooj yim rau txheej txheem. Kev nkag siab txog qhov sib txawv ntawm cov ntaub ntawv no tuaj yeem pab xaiv cov khoom tsim nyog rau kev tsim khoom tshwj xeeb, ua rau nws yog ib qho tseem ceeb rau cov tuam txhab nrhiav kev tsim cov khoom zoo thaum txo kev cuam tshuam ib puag ncig.

Ntawm no yog ibDaim ntawv sib piv ntawm CPU thiab TPU
