Acrylic yog dab tsi?
Jul 11, 2018
Acrylic cov khoom muaj xws li acrylic hnab, acrylic yas pellets, acrylic lub thawv, kos npe, acrylic bathtubs, acrylic khoom ci marble, acrylic resin, acrylic (latex) xim, acrylic adhesives, etc., thiab ntau yam.
Acrylic khoom, uas tam sim no siv feem ntau, yog ua los ntawm acrylic pellets, daim hlau los yog lwm yam ntaub qhwv, thiab sib sau ua ke nrog ntau yam ntaub ntawv thiab cov khoom ua haujlwm. Acrylic fiber, acrylic paj rwb, acrylic yarn, acrylic nylon, etc., uas feem ntau hnov, yog cov txiv neej ua fibers polymerized ntawm acrylic acid thiab tsis txheeb cov acrylic khoom. Feem ntau, cov ntaub ntawv acrylic yog feem ntau hu ua polymethyl methacrylate Polymeric Methyl Methacrylate (PMMA) ntawv, uas yog polymerized los ntawm "methyl methacrylate monomer (Methyl Methacrylate (MMA)" los yog extruded los ntawm acrylic pellets los ntawm extruder. lub phaj feem ntau yog hu ua cov lus pleev xim.
Acrylic txhais tau hais tias PMMA lub Rooj Tswjhwm Saib cov MMA ntawm cov organic compound, uas muaj transparency thiab transparency zoo li iav. Tag nrho cov ntawv ua los ntawm cov khoom uas nrov xws li PS, PC, thiab lwm yam los yog los ntawm kev ua tsis zoo dua MMA yog cov npe hu ua plexiglass. For the sake of separation, lub PMMA pawg thawj coj ua los ntawm cov khoom siv zoo ntshiab MMA yog ib txwm raug xa mus rau cov ntaub ntawv acrylic, thiab tau sib cais los ntawm lub rooj tsav khoom dav hlau
Acrylic khoom feature
1. Thickness Acrylic Tolerance: Acrylic sheet thickness muaj acrylic kam rau ua, yog li qhov kev tswj ntawm acrylic kam rau siab yog ib qho tseem ceeb ntawm kev tswj kev tswj thiab kev siv technology. Cov tshuaj acrylic muaj cov txheej txheem thoob ntiaj teb ISO7823 casting yuav tsum ua raws li kev cai: tolerance = ± (siab tawv + 0.4 mm x 0.1) Whiteness: Xaiv cov khoom raw, cov qauv siab ntxiv thiab cov txheej txheem niaj hnub tsim kom muaj kev kaj siab zoo thiab cov xim ntawm cov txwj laus. Tom qab lub nplaim taws nquag, nws yog qhov tseeb.
2. Hardness: Hardness yog ib qho ntawm qhov tsis zoo tshaj plaws yog qhia cov txheej txheem thiab kev siv technology ntawm casting acrylic ntawv, thiab yog qhov tseem ceeb ntawm txoj kev tswj kom zoo. Lub hardness yuav muaj kev cuam tshuam cov purity ntawm raw cov ntaub ntawv PMMA, huab cua tsis kam ntawm daim ntawv, thiab kub siab ua hauj. Kev ua haujlwm ncaj qha cuam tshuam rau cov ntaub ntawv yuav ua kom poob thiab khoov, thiab seb qhov yuav tawg yuav tawg thaum lub sijhawm ua haujlwm. Hardness yog ib qhov nyuaj thiab zoo ntsuas rau judging qhov zoo ntawm acrylic los xij, thiab qhov nruab nrab cov nqi Dalhou hardness yog li 89 degrees.
