Dab tsi yog cov khoom ntawm acrylic phaj?
Acrylic phaj, tseem hu ua PMMA los yog acrylic phaj, los ntawm lus Askiv acrylic (acrylic yas), transliteration yog "acrylic phaj" (yog li "acrylic phaj" yog ib tug transliteration lo lus), tshuaj lub npe yog polymethyl methacrylate.
Acrylic phaj yog cov khoom siv yas polymer, nrog lub teeb pom kev zoo, tshuaj lom neeg ruaj khov thiab huab cua tsis kam, xim yooj yim, yooj yim tsim thiab ua, zoo nkauj tsos, tau siv dav hauv kev tsim kho kev lag luam. Organic iav phaj khoom feem ntau tuaj yeem muab faib ua cov phaj nchuav, phaj extrusion.
Cov yam ntxwv ntawm acrylic ntawv
1, nrog crystal-zoo li pob tshab, transmittivity ntawm ntau tshaj 92 feem pua, lub teeb mos, pom tseeb, nrog dyes xim acrylic ntawv thiab muaj xim zoo.
2, acrylic phaj muaj cov huab cua tsis zoo, siab dua qhov tawv tawv thiab nto gloss, thiab kev ua haujlwm kub zoo dua.
3, acrylic phaj muaj kev tsim khoom zoo thiab kev ua haujlwm, tuaj yeem siv kub sib sau, tuaj yeem siv tshuab ua haujlwm.
4, pob tshab acrylic phaj yuav zoo ib yam li iav transmittance, ceev yog ib nrab ntawm iav. Tsis tas li ntawd, nws tsis yooj yim li iav, thiab txawm tias tawg, nws yuav tsis ua rau lub ntsej muag ntse li iav.
5, hnav tsis kam ntawm acrylic phaj yog ze rau ntawm txhuas, resistant rau ntau yam tshuaj corrosion.
6, acrylic phaj muaj kev luam ntawv zoo thiab txau, siv cov txheej txheem luam ntawv tsim nyog thiab txau, tuaj yeem muab cov txheej txheem acrylic zoo tagnrho rau kev kho kom zoo nkauj.
7, nplaim retardant: tsis spontaneous combustion tab sis belongs rau cov khoom flammable, tsis muaj self-extinguishing.
Daim ntawv thov ntawm acrylic ntawv
PMMA muaj qhov zoo ntawm lub teeb yuag, pheej yig thiab yooj yim rau kev tsim. Nws txoj kev tsim muaj xws li casting, extrusion, kub sib sau thiab lwm yam. Tshwj xeeb tshaj yog extrusion txoj kev, tuaj yeem ua ntau lawm, txheej txheem yooj yim, tus nqi qis. Yog li ntawd, nws yog dav siv los ua cov cuab yeej cuab yeej cuab tam, lub tsheb teeb, lub teeb pom kev zoo, cov kav dej pob tshab thiab lwm yam.
Vim tias kev tsim cov ntawv acrylic yog qhov nyuaj thiab kim, muaj ntau yam tsis zoo thiab pheej yig lwm txoj hauv kev lag luam. Lwm txoj hauv kev no tseem hu ua "acrylic sheet", yog qhov ua tau zoo tib yam plexiglass lossis pawg thawj coj saib (tseem hu ua sandwich board). Ordinary organic iav phaj yog cam khwb cia nrog zoo tib yam organic iav phaj cracking cov ntaub ntawv thiab cov xim, lub deg hardness yog tsawg, yooj yim rau ploj, thiab cov nyhuv polishing yog tsis zoo tom qab sib tsoo nrog nplua xuab zeb. Lub rooj sib xyaw ua ke tsuas yog muaj txheej nyias ntawm acrylic ntawv ntawm qhov chaw, thiab ABS yas yog nyob rau hauv nruab nrab. Nws yog ib qho yooj yim rau delamination hauv kev siv vim thermal expansion thiab txias contraction. Daim ntawv acrylic tseeb lossis cuav tuaj yeem txheeb xyuas los ntawm cov xim zoo sib txawv thiab polishing nyhuv ntawm daim ntawv seem.
