Qhov sib txawv tseem ceeb ntawm polycarbonate thiab acrylic yog tias polycarbonate yuav luag tsis tawg, qhov acrylic tuaj yeem tawg tau yog tias siv zog ntau dua.
Yas yog ib qho polymer uas muaj cov molecular loj. Cov monomers ntawm yas yog tej yam ntuj tso los yog hluavtaws. Yas yog synthesized los ntawm petrochemicals. Muaj ob hom yas: thermoplastics thiab thermosetting polymers. Tsis tas li ntawd, plastics tau siv dav hauv ntau hom, xws li lub raj mis, hnab, thawv, fibers, thiab zaj duab xis. Cov yas sib txawv muaj lub zog sib txawv tab sis muaj lub teeb yuag. Polycarbonate thiab acrylic yog ob hom yas uas txawv me ntsis ntawm cov yas qub. Ob leeg zoo li iav, tab sis cov yas muaj zog.
YPolycarbonate yog dab tsi?
Polycarbonate yog hom yas. Nws yog tawv heev, yog li ntawd, nyuaj heev rau tawg. Lawv yog cov polymers. Monomer chav tsev ntawm no muaj carbonate pawg; Yog li ntawd, peb muab lawv li polycarbonates. Cov ntaub ntawv polymer no ua los ntawm kev sib txuas ua ke nrog cov qauv tshuaj hauv qab no.
Daim duab 01: Polycarbonate Structure
Peb tuaj yeem tsim cov polymer no los ntawm cov tshuaj tiv thaiv ntawm bisphenol A thiab phosgene COCl 2 Cov no yog cov khoom hnyav molecular polymers. Ntxiv mus, polycarbonates tig mus rau hauv lub xeev ua kua thaum peb sov nws; Thaum peb txias nws, nws khov rau hauv lub xeev iav. Yog li ntawd, peb tuaj yeem hu lawv ua cov thermoplastics. Yog li ntawd, lawv tuaj yeem yooj yim molded thiab zoo li tus rau hauv cov ntawv xav tau. Vim tias cov cuab yeej no, polycarbonates tseem ceeb hauv ntau daim ntawv thov.
Ntxiv mus, polycarbonates yog qhov ruaj khov thiab tiv taus heev. Lawv ruaj khov nyob rau hauv qhov kub siab dua li 280 ° F thiab qis dua li -40 ° F yam tsis muaj deformation. Lawv kuj yog pob tshab rau pom lub teeb. Yog li ntawd, polycarbonates muaj txiaj ntsig zoo rau kev tsim cov qhov rais bulletproof, tsom iav, thiab lwm yam. Qhov zoo ntawm kev siv polycarbonates es tsis txhob siv iav los yog lwm yam yas yog tias cov polymer no muaj lub teeb yuag, tab sis muaj zog dua piv rau lwm tus.
Daim duab 02: Polycarbonate
Ntxiv rau, nws muaj qhov ntsuas siab siab thiab tuaj yeem khoov thiab ua cov iav nrog tuab tuab. Lens ua los ntawm polycarbonate yog nyias, thiab lawv khoov lub teeb ntau dua li iav los yog yas. Polycarbonates kuj tseem ceeb heev los ua cov disks (CDs) thiab Digital ntau yam discs (DVD)s. Tsis tas li ntawd, cov khoom siv no muaj txiaj ntsig zoo hauv electronics. Piv txwv li, lub xov tooj ntawm tes, laptop lossis lub computer npog yog tsim los ntawm polycarbonates. Lawv yog cov tseem ceeb raws li automotive Cheebtsam.
YAcrylic yog dab tsi?
Acrylic kuj yog cov thermoplastic zoo li polycarbonate thiab pob tshab thiab. Qee zaum peb hu nws acrylic iav vim nws yog qhov tseem ceeb los hloov iav. Ntxiv mus, peb siv ntau lub npe xws li Poly (methyl methacrylate) lossis PMMA. Poly (methyl 2-methylpropenoate) yog IUPAC lub npe ntawm acrylic, thiab nws muaj cov qauv hauv qab no.
Daim duab 03: Acrylic
Qhov no yog ib qho muaj zog, hnav thiab tawg cov yas tiv taus. Qhov tseeb, acrylic muaj zog dua iav. Acrylic yog siv los ua qhov rais, iav qhov rooj, skylights, thiab lwm yam.
Qhov txawv ntawm Polycarbonate thiab Acrylic yog dab tsi?
Polycarbonate yog qhov ruaj khov, pob tshab thermoplastic nrog cov qauv uas tso cai rau kev cuam tshuam zoo heev. Acrylic, ntawm qhov tod tes, yog cov pob tshab thermoplastic feem ntau siv hauv daim ntawv ua lub teeb yuag lossis tawg-tiv taus rau iav. Qhov sib txawv tseem ceeb ntawm polycarbonate thiab acrylic yog tias polycarbonate yuav luag tsis tawg, hos acrylic tuaj yeem tawg tau yog tias siv zog ntau dua.
Ntxiv mus, cov khoom siv polycarbonate muaj qhov ci tsawg dua piv rau acrylic. Polycarbonate kuj muaj kev cuam tshuam siab, tab sis acrylic muaj qhov cuam tshuam tsis zoo. Tsis tas li ntawd, polycarbonate yog kim dua li acrylic.
Summary – Polycarbonate vs Acrylic
Polycarbonate thiab acrylic yog ob hom pob tshab yas. Qhov sib txawv tseem ceeb ntawm polycarbonate thiab acrylic yog tias polycarbonate yuav luag tsis tawg, hos acrylic tuaj yeem tawg tau yog tias siv zog ntau dua.
