Acrylic Sheet
PMMA muaj qhov zoo ntawm lub cev nyhav, luv nqi, yooj yim molding, thiab lwm yam.
Nws txoj kev molding yog casting, txhaj tshuaj molding, machining, thermoforming thiab thiaj li. Tshwj xeeb tshaj yog cov kev txhaj tshuaj molding, yuav ua tau ntau lawm. Tus txheej txheem yog yooj yim thiab luv nqi. Yog li ntawd, nws yog nce dav siv. Nws yog tam sim no dav siv hauv cov cuab yeej ntsuas, tsheb teeb, qhov muag lo ntsiab muag kho, kav dej thiab zoo li ntawd.
1. Daim ntawv thov pleev xim plexiglass acrylic hauv kev tsim kho kev lag luam.
Hauv tsev, cov pob zeb pleev xim pleev yog siv hauv cov xov tooj hu xov tooj, stairs thiab chav phab ntsa panels thiab lwm yam. Hauv cov khoom ua kom huv, nws tsuas yog pom hauv da dej, ntxhua khaub ncaws, hnav khaub ncaws thiab lwm yam khoom. Nyob rau hauv xyoo tas los, nws txoj kev loj hlob kuj yog ib qho tseem ceeb heev hauv txoj kev loj, txoj kev teeb pom kev zoo siab nyob rau hauv high school thiab kev siv lub teeb nrawm tsheb. Ntawm lawv, tsev teeb pom kev zoo, lub dab da dej, lub qhov muag tsheb thawv, cov xov tooj hu xov tooj thiab lwm yam kev lag luam sai dua, kev loj hlob yav tom ntej muaj qhov chaw loj thiab cov khoom lag luam muaj ntau heev.
Nyob rau hauv xyoo tas los, Tuam Tshoj lub teeb pom kev lag luam tsim tau sai nrog txoj kev tsim kho cov nroog loj xws li tsev noj mov, chaw ntiav pw thiab cov tsev laus. Nrog cov neeg pleev roj pleev tsis zoo ntawm lub teeb plexiglass, nws muaj peev txheej thoob plaws lub zog, kev xa tawm siab, kev nyab xeeb siab thiab lwm yam tshwj xeeb zoo. Piv nrog rau cov iav teeb pom kev zoo hauv inorganic, muab piv nrog ib tus zoo dua.
Tam sim no, Tebchaws Asmeskas thiab Nyij Pooj tau yuam txoj cai, cov tsev kawm ntawv theem nrab thiab theem nrab thiab tsev kawm ntawv qib kindergarten, yuav tsum siv cov tshuaj pleev xim pleev xim. Nrog rau kev txhim kho cov kev cai lij choj thiab cov cai tswj hwm, suav tias yuav tsum tau nyob rau yav pem suab, Tsoom Fwv Txoj Cai kuj yuav tsum kom thawj tsev kawm ntawv theem ob thiab cov tsev kawm ntawv qib kindergarten yuav tsum tau siv cov twj pleev xim. Tib lub sijhawm, Tuam Tshoj tau ceev txoj haujlwm ntawm kev tsim nroog, txoj kev qhia, cov duab thawv tshaj tawm thiab cov xov tooj hu xov tooj, uas yog ib feem ntau ntawm cov khoom siv uas siv los ua cov khoom pleev xim.
Nyob rau hauv cov khoom ua kom huv si, vim cov pleev xim pleev xim pleev xim pleev xim muaj qhov zoo nkauj, lub siab tob tob, yooj yim los ntxuav, lub zog, lub cev nyhav thiab kev siv cov kev nplij siab thiab lwm yam ntxwv, thaum xyoo tas los tau siv dav dav, zus tau ntau tshaj li ntawm 1.5 plhom, muaj noj txhua xyoo PMMA extrusion board lossis casting board ntau dua 5,000 tons.
Nrog rau kev tsim kho ntawm Tuam Tshoj cov cai thiab cov kev tswj cai, PMMA yuav siv ntau daim ntawv sau npe los ua kom paub ntau dua competitiveness.
Tsis tas li ntawd, tshwj xeeb lub tshuab tsis zoo, xws li cov twj pleev xim tsis zoo, cov duab hluav taws xob tsis zoo thiab CD-level plexiglass nyob rau hauv Suav teb kev lag luam kev lag luam tseem tsis tau muaj. Nws muaj chav loj dua rau txoj kev loj hlob.
2.China cov kua qaub (acrylic acrylic) PMMA cov khoom noj thiab kev lag luam.
Tuam Tshoj tam sim no tag nrho muaj peev xwm ntawm cov khoom ua cov khoom nyob rau hauv nissan yog li 130,000 tons. Muaj ntau cov tuam ntxhab, tab sis cov nplai muaj me me.
Tuam Tshoj tus plexiglass acrylic ntau lawm thiab ua muaj peev xwm loj heev, tab sis cov khoom qauv tsis tsim nyog.Yuav muaj peev xwm tsim tau cov yam ntxwv zoo tib yam ntawm cov khoom. Cov tsis muaj kev tsim kho cov khoom muaj nqis ntxiv hauv ntau yam thiab tsis muaj peev xwm ua tsis tau raws li cov kev xav tau ntawm lub khw. Xws li kev tsim kho nrog coob tus xav tau rau lub rooj tsav xwm extrusion yuav tsum tau import ntau tus loj dua los ntawm abroad.
Nyob rau hauv xyoo tsis ntev los no, Tuam Tshoj lub plexiglass acrylic noj kev loj hlob yog heev ceev ceev. Tab sis vim hais tias Tuam Tshoj lub suab Plexiglass PMMA cov khoom muaj ntau, tsawg dua, tsis zoo thiab deb ntawm kev xav tau ntawm kev ua lag luam domestic, ua rau muaj ntau yam tuaj pauv ntau xyoo tuaj txawv teb chaws. Nyob rau hauv 2000, Suav teb PMMA molding compound imports mus txog 77,000 tons thaum imports ntawm plexiglass phaj luag 4,000 tons. Los ntawm cov cheeb tsam ntshuam, Guangdong, Shanghai, Zhejiang thiab Jiangsu provincial thiab lub zos total imports account rau txog 95% ntawm Tuam Tshoj tus tag nrho cov tuaj txawv teb chaws. Jiangsu thiab Shanghai yog qhov chaw ua haujlwm loj tshaj plaws ntawm plexiglass castings hauv Suav teb. Vim hais tias kev yooj yim casting thiab tsawg peev, ntau lub zos cov lag luam siv cov txheej txheem no rau kev cob qhia kev ua haujlwm. Ua rau cov khoom me me thiab qhov khoom zoo yog deb tsawg dua qhov zoo ntawm cov qauv ntaub ntawv kev lag luam, qauv pouring ntev tau raug tshem tawm hauv cov teb chaws txawv teb chaws.
Nyob rau hauv 1980s, Suav teb Acrylic plexiglass muag khoom ntawm tsawg dua 20,000 tons. Kev tsim kho kev lag luam tsis yog lub khw muag khoom loj. Txij li thaum xyoo 1990, PMMA hauv kev tsim ua lag luam muaj kev lag luam ntau dua. Nws noj kev loj hlob sai. Nyob rau hauv 2000 nws tau mus txog 85,000 tons, uas 29,000 tons ntawm cam khwb cia phaj, extrusion phaj 25,000 tons, molding compound 3.1 lab tons (molding ntawm extruded daim hlau tsis muaj). Lub xyoo tom ntej no, Tuam Tshoj txoj kev loj hlob ntawm cov lag luam hu ua Acrylic Plexiglass development yuav nyob rau 6% hauv ib lub xyoo. Nws yuav tsum tau hais tias los ntawm 2005, Tuam Tshoj tus acrylic plexiglass muaj peev xwm ntawm 110,000 tons, ntawm qhov kev lag luam kev lag luam txhawm rau li 60% txog 70%.
Thaum ntxov li xyoo 1920, Rohm thiab Haaxin ua ntej siv txoj kev siv PMMA polymerization rau acrylic panels (acrylic phaj). Cov phaj no hu ua "oroglas / plexiglass". Txawm li cas los xij, lub tuam txhab tsis tau pom qhov kev lag luam ntau PMMA cov txheej txheem, yog li ntawd lub phais acrylic (acrylic board) tsis muaj peev xwm ua tau lub luag haujlwm tseem ceeb.
Nyob rau hauv 1931, ICI cov neeg tshawb nrhiav cov khoom ntawm MMA acetone cyanohydrin txujci, hom no zoo heev txo cov nqi PMMA, yog li ntawd cov phom acrylic yuav universal. Tib lub sij hawm, ICI kuj tau ntse tau tsim cov vaj huam sib luag acrylic (acrylic board) rau cov dav hlau dav hlau thiab lwm qhov chaw, ces ICI lub tuam txhab hauv United Kingdom tau tsim lub ntiaj teb ua cov ntaub ntawv loj tshaj acrylic.
