Thaum koj los ntawm peb lub vev xaib, koj yuav pom qee yam khoom siv yog PC lossis TPU.Tab sis dab tsi, raws nraim, puas yog PC / TPU?Thiab dab tsi txawv nrog PC thiab TPU?Cia peb pib nrog tsab xov xwm no.
PC
Polycarbonate (PC) yog hais txog ib pawg ntawm cov thermoplastic polymers encompassing carbonate pawg hauv lawv cov qauv tshuaj.PC siv hauv engineering muaj zog thiab tawv.Qee qib yog optically pob tshab thiab siv rau polycarbonate lo ntsiab muag.Lawv tau yooj yim ua hauj lwm, molded.Vim tias cov khoom siv tshuaj no, PC muaj ntau daim ntawv thov.
Polycarbonate yog ib qho thermoplastic pom ze li ntawm txhua qhov chaw.Nws yog siv rau hauv cov tsom iav qhov muag, cov khoom siv kho mob, cov iav tiv thaiv, qhov chaw pib, DVDs, thiab cov teeb pom kev zoo.Raws li ib txwm pob tshab amorphous thermoplastic, polycarbonate yog qhov tseem ceeb vim tias nws tuaj yeem xa lub teeb sab hauv yuav luag zoo li iav thiab tuaj yeem tiv taus qhov cuam tshuam tseem ceeb dua li ntau yam siv lwm cov yas.
Common crafts ntawm PC
Cov txheej txheem ntau lawm los tsim cov khoom siv polycarbonate yog: Txhaj tshuaj molding, Extrusion.
Txhaj tshuaj molding
Kev txhaj tshuaj molding yog txoj hauv kev tshaj plaws los tsim cov polycarbonate thiab lawv cov khoom sib xyaw.Polycarbonate yog viscous heev.Nws yog feem ntau ua tiav ntawm qhov kub thiab txias kom txo nws cov viscosity.Nyob rau hauv cov txheej txheem no, cov kub polymer yaj yog nias los ntawm kev mus rau hauv lub pwm nrog kev kub siab.Cov pwm thaum txias muab cov molten polymer nws cov duab thiab cov yam ntxwv.
Yas Txhaj Tshuaj Kho Mob Khoom Siv Tsev
Extrusion
Nyob rau hauv cov txheej txheem extrusion, cov polymer yaj yog dhau los ntawm cov kab noj hniav uas pab muab nws cov duab kawg.Lub yaj thaum txias attains thiab tswj cov duab tau.Cov txheej txheem no yog siv los tsim cov nplooj ntawv polycarbonate, profiles, thiab kav ntev.
Dab tsi yog qhov zoo ntawm kev siv PC?
Nws yog qhov ruaj khov heev, cuam tshuam-resistant, thiab yuav tsis tawg lossis tawg
Nws yog kub resistant thiab yog li yooj yim rau pwm, ua rau nws zoo tagnrho rau ntau yam kev siv
Nws yog ib qho yooj yim recyclable uas txhais tau hais tias nws kuj zoo rau ib puag ncig
TPU
Thermoplastic polyurethane (TPU) yog cov yaj-ua tau thermoplastic elastomer nrog cov kav ntev thiab yoog raws.Nws tuaj yeem siv tau los ua cov khoom luam tawm hauv ob hom 3D tshuab luam ntawv-Fused Deposition Modeling (FDM) tshuab luam ntawv thiab Selective Laser Sintering (SLS) tshuab luam ntawv.
TPU los ntawm ntau yam xim opaque thiab pob tshab.Nws qhov chaw ua tiav tuaj yeem ua tau los ntawm du mus rau ntxhib (kom muab tuav).Ib qho tshwj xeeb ntawm TPU yog tias nws cov tawv tawv tuaj yeem kho tau.Qhov kev muaj peev xwm tswj tau qhov hardness no tuaj yeem ua rau cov khoom siv xws li muag muag (rubbery) mus rau tawv (cov yas khov).
Kev siv ntawm TPU
Daim ntawv thov ntawm TPU yog ntau yam.Kev lag luam uas siv cov khoom luam tawm TPU suav nrog aerospace, tsheb, khau, kis las, thiab kev kho mob.TPU kuj tseem siv tau los ua ib lub hnab rau cov xov hlau hauv kev lag luam hluav taws xob thiab ua cov ntaub ntawv tiv thaiv rau cov khoom siv hluav taws xob, xws li xov tooj ntawm tes lossis ntsiav tshuaj.
Dab tsi yog qhov zoo ntawm kev siv TPU?
Nws yog heev abrasion resistant, uas tiv thaiv nws los ntawm khawb thiab khawb
Nws tshwj xeeb elasticity tso cai rau nws yooj yim molded rau ntau yam kev siv
Nws yog pob tshab, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov xov tooj ntshiab thiab lwm yam pom los ntawm cov khoom
Nws yog roj thiab roj resistant, uas ua rau grubby prints los ntawm lo rau cov khoom ua los ntawm TPU
Cov ntsiab lus
Kab lus no tau tham txog Polycarbonate (PC), hais txog nws yog dab tsi, nws siv, nws cov khoom siv sib xws, thiab qhov zoo.RuiCheng muaj ntau yam khoom siv tes ua txog polycarbonate nrog rau kev txhaj tshuaj thiab extrusion.Daim ntawv cog lus rau pebrau ib nqe lus ntawm koj cov khoom siv tes ua polycarbonate xav tau.
