Qhov sib txawv tseem ceeb ntawm TPU thiab silicone yog cov khoom siv TPU zoo dua li silicone siv los tsim cov xov tooj ntawm tes.
Ob leeg TPU thiab silicone yog siv los tsim cov xov tooj ntawm tes lossis npog. Ob cov ntaub ntawv no feem ntau siv rau daim ntawv thov no vim lawv muaj peev xwm tiv thaiv lub xov tooj ntawm tes. Piv txwv li, cov khoom siv TPU tuaj yeem tiv thaiv lub xov tooj ntawm kev sib tsoo, tsis muaj kev puas tsuaj rau lub xov tooj. Ntxiv mus, cov khoom siv TPU yog pob tshab ntau dua hauv cov xim thiab ib puag ncig tus phooj ywg.
TPU yog dab tsi?
Lub sij hawm TPU sawv cev rau thermoplastic polyurethane. Nws yog ib chav kawm ntawm polyurethane yas muaj ntau yam khoom xws li elasticity, pob tshab, thiab tsis kam mus rau roj, roj, thiab puas. Peb tuaj yeem faib lawv ua cov thermoplastic elastomers. Cov khoom no muaj cov kab segmented thaiv copolymer uas muaj cov ntu tawv thiab mos.
Thermoplastic polyurethane yog ib qho thaiv copolymer tsim los ntawm kev sib txuas ntawm cov ntu tawv thiab muag muag lossis cov khoom tawg uas yog tsim los ntawm cov tshuaj tiv thaiv ntawm diisocyanate nrog cov saw luv luv diols thiab cov tshuaj tiv thaiv ntawm diisocyanates nrog cov saw ntev diols. Peb tuaj yeem tau txais ntau yam khoom siv TPU los ntawm kev hloov qhov piv, qauv lossis molecular hnyav ntawm cov reactants. E.g. Yog tias qhov sib piv ntawm cov ntu tawv thiab mos yog qhov zoo, ces qhov ua rau TPU yog qhov sib piv nruj dua.

Cov khoom thaiv copolymer no muaj cov polarity tsawg. Ob qho tib si nyuaj thiab mos hauv cov polymer no txuas rau ib leeg ntawm covalent txuas, yog li lawv tsim thaiv cov qauv copolymer. Lub polarity ntawm cov ntu nyuaj ua rau muaj kev nyiam ntawm cov ntu no. Qhov no ua rau muaj kev sib sau ua ke thiab kev txiav txim siab, uas ua rau hauv cov khoom siv crystalline lossis cov khoom siv pseudocrystalline. Cov crystalline lossis pseudo crystalline thaj chaw hauv cov khoom siv no tuaj yeem ua raws li lub cev sib txuas hauv cheeb tsam, uas ua rau lub siab elasticity ntawm TPU.
Y Silicone yog dab tsi?
Silicone yog cov khoom siv tsis muaj sia uas peb siv los ua sealants, adhesives, lubricants, tshuaj, thiab lwm yam. Peb hu nws ua polysiloxanes thiab. Nws yog lub npe tshuaj ntawm no compound. Cov no yog cov ntaub ntawv polymer uas muaj cov chav nyob ntawm siloxanes rov ua dua. Feem ntau, silicone yog kub resistant thiab yog ib yam khoom siv roj hmab. Txawm li cas los xij, qee zaum, peb tuaj yeem pom nws hauv nws daim ntawv ua kua ib yam nkaus, nyob ntawm daim ntawv thov npaj. Nws yog ib qho zoo thermal thiab hluav taws xob insulator. Cov tebchaw uas peb siv hauv lub neej niaj hnub muaj xws li roj silicone, roj silicone, roj hmab silicone, silicone resin, thiab silicone caulk.

Cov khoom sib xyaw no tuaj yeem ua rau cov dej tsis sib haum. Txawm li cas los, nws muaj ib tug high gas permeability. Qhov ntawd txhais tau tias, nws yog permeable heev rau cov pa roj xws li oxygen, uas ua rau nws muaj txiaj ntsig zoo hauv kev kho mob uas peb xav tau ntau dua aeration. Peb tuaj yeem siv silicone nyob rau hauv lub tsheb ua lag luam raws li cov roj silicone los ua cov roj nplua nyeem rau cov nres. Nws kuj tseem muaj txiaj ntsig zoo hauv cov txheej txheem thiab muab cov chaw muaj peev xwm tiv thaiv dej. Txij li cov silicone tsis muaj tshuaj lom thiab tsis muaj tshuaj lom, peb tuaj yeem siv cov khoom sib xyaw no thaum peb xav tau los ua cov cuab yeej uas tuaj rau hauv kev sib cuag nrog zaub mov. Cov kua silicone muaj txiaj ntsig zoo li cov tshuaj ntxuav kom qhuav. Ntxiv mus, nws tiv taus cov kab mob microbial, uas muab cov khoom no nrog lub neej ntev.
Qhov txawv ntawm TPU thiab Silicone yog dab tsi?
Qhov sib txawv tseem ceeb ntawm TPU thiab silicone yog cov khoom siv TPU zoo dua li silicone siv los tsim cov xov tooj ntawm tes. Qhov no yog vim tias cov khoom siv silicone yog cov khoom siv hluav taws xob tsis zoo uas tuaj yeem khaws cov cua sov hauv lub xov tooj ntawm tes uas tuaj yeem ua rau lub xov tooj cua sov thaum kawg. Tab sis cov khoom siv TPU tuaj yeem ua cua sov tawm ntawm lub xov tooj thiab tsis khaws cov cua sov li hauv silicone. Yog li, lub xov tooj muaj kev nyab xeeb hauv lub hau no. Ntxiv mus, TPU cov ntaub ntawv yog pob tshab ntau xim, ib puag ncig tus phooj ywg, thiab tseem ceeb tshaj, nrog TPU rooj plaub, tus neeg siv yuav tsis poob tuav ntawm lub xov tooj yooj yim.
Hauv qab infographic piv cov ntaub ntawv thiab tabulates ib sab ntawm qhov sib txawv ntawm TPU thiab silicone.
Summary – TPU vs Silicone
Qhov sib txawv tseem ceeb ntawm TPU thiab silicone yog cov khoom siv TPU zoo dua li silicone siv los tsim cov xov tooj ntawm tes. Ntxiv mus, TPU cov ntaub ntawv yog pob tshab ntau xim, ib puag ncig tus phooj ywg, thiab tseem ceeb tshaj, TPU muab tus neeg siv tuav lub xov tooj zoo.
