Peb tab tom pom qhov nce ntawm tus nqi ntawm smartphones. Nco ntsoov thaum twg $1,000 raug suav hais tias yog kev npau taws? Zoo, Samsung tso tawm Note 20 nrog sub-par specs ntawm ib txhiab bucks. Nrog cov xov tooj kim kim tuaj pheej hmoo ua rau lawv puas tsuaj. Thiab thaum nws los txog rau kev tiv thaiv, muaj ob txoj kev xaiv; txuas ntxiv warranty thiab xov tooj, feem ntau yog silicone thiab TPU. Cia peb muab ob sab ntawm ib sab hauv qhov noCov khoom siv TPUvs Silicone sib ntaus sib tua thiab saib dab tsi yog cov ntaub ntawv no thiab qhov twg yog qhov zoo dua.
Ob leeg TPU thiab silicone yog cov ntaub ntawv polymer-raws li thiab siv hauv ntau lub lag luam rau lawv lub cev zoo. Ob leeg cov ntaub ntawv yog mos, mouldable, thiab yooj yim los tsim. Qhov no yog vim li cas cov xov tooj uas ua los ntawm ob qho no yog pheej yig thiab yooj yim muaj. Ob qho tib si cov ntaub ntawv muaj qee qhov zoo thiab qhov tsis zoo thiab nyob ntawm qhov tshwj xeeb zoo uas lawv muaj, cov xov tooj yog nyiam.
TPU txhais li cas?
TPU sawv cev rau Thermoplastic Polyurethane. Peb yuav tsis mus dhia dej rau hauv cov organic chemistry ib feem ntawm cov khoom no. Nws yuav txaus los hais tias TPU yog ua los ntawm kev rov ua cov chains ntawm block copolymer. Txhawm rau kom nkag siab nws, xav txog cov qauv mesh nrog ib qho chaw ntawm kev sib tshuam. Cov dots yuav yog qhov thaiv copolymer thaum cov kab yuav yog cov txuas txuas.
TPU tsis yog siv los ua cov xov tooj lossis lwm yam. Koj puas tau pom cov sponges ntxuav tais diav? Cov no yog ua los ntawm polyurethane, ib feem ntawm TPU. TPU yog ntau yam, nws siv xws li kev ntxuav tais diav mus rau cov khoom siv kho mob. Tab sis dab tsi ua rau cov khoom siv TPU no apt rau ua cov xov tooj?
Txij li nws yog ib qho polymer, muaj qee qhov zoo heev uas TPU muaj cov ntaub ntawv tseem xav tau. Qhov tseem ceeb tshaj plaws yog nws qhov kev ua haujlwm siab abrasion. Tab sis ua ntej peb paub TPU zoo dua, cia peb kawm vim li cas nws yog cov khoom zoo li no rau cov xov tooj thiab lwm yam khoom siv. Cia peb saib cov khoom siv PC.
