Keeb Kwm Kev Loj Hlob ntawm Acrylic yog dab tsi?

Raws li peb txhua tus paub, acrylic kuj hu ua plexiglass kho tshwj xeeb. Acrylic iav yog cov thermoplastic pob tshab uas tsis hnyav thiab tsis tawg, ua rau nws yog lwm txoj hauv kev zoo rau iav. Cov hom iav ua los ntawm tib neeg hnub rov qab mus rau 3500 BC, thiab kev tshawb fawb thiab kev txhim kho ntawm acrylic muaj ntau tshaj ib puas xyoo keeb kwm.

Xyoo 1872, kev polymerization ntawm acrylic acid tau pom.

Xyoo 1880, qhov kev polymerization ntawm methyl acrylic acid tau paub.

Xyoo 1901, kev tshawb fawb ntawm propylene polypropionate synthesis tau ua tiav.

Xyoo 1907, Dr. Röhm tau txiav txim siab los nthuav nws txoj kev tshawb fawb txog acrylic acid ester polymerisate, ib yam khoom tsis muaj xim thiab pob tshab, thiab nws yuav siv li cas rau kev lag luam.

Xyoo 1928, lub tuam txhab tshuaj lom neeg Röhm thiab Haas tau siv lawv cov kev tshawb pom los tsim Luglas, uas yog lub iav kev nyab xeeb siv rau lub qhov rais tsheb.

Dr. Röhm tsis yog tib tug neeg uas tsom mus rau iav kev nyab xeeb - thaum ntxov xyoo 1930, cov kws tshuaj Askiv ntawm Imperial Chemical Industries (ICI) tau tshawb pom polymethyl methacrylate (PMMA), tseem hu ua iav acrylic. Lawv tau sau lawv cov kev tshawb pom acrylic ua Perspex.

Cov kws tshawb fawb ntawm Röhm thiab Haas tau ua raws li tom qab; lawv sai sai pom tias PMMA tuaj yeem polymerized ntawm ob daim iav thiab cais ua nws daim iav acrylic. Röhm tau sau npe ua Plexiglass hauv xyoo 1933. Nyob ib puag ncig lub sijhawm no, EI du Pont de Nemours & Company uas yug hauv Tebchaws Meskas (feem ntau hu ua DuPont) kuj tau tsim lawv cov iav acrylic hauv qab lub npe Lucite.

Thaum Tsov Rog Thoob Ntiaj Teb Zaum Ob, nrog lub zog zoo heev thiab kev tawv thiab kev sib kis lub teeb, acrylic tau siv thawj zaug rau lub qhov rais ntawm cov dav hlau thiab daim iav ntawm cov tank.

Thaum Tsov Rog Thoob Ntiaj Teb Zaum Ob xaus, cov tuam txhab uas ua cov acrylics tau ntsib teeb meem tshiab: lawv yuav ua dab tsi tom ntej? Kev siv cov iav acrylic rau kev lag luam tau pib tshwm sim thaum xyoo 1930s thiab thaum ntxov xyoo 1940s. Cov yam ntxwv uas tiv taus kev cuam tshuam thiab kev tawg uas ua rau acrylic zoo rau lub qhov rais thiab lub qhov rais tam sim no tau nthuav dav mus rau lub kaus mom hlau, lub lens sab nraud ntawm lub tsheb, cov khoom siv tub ceev xwm tawm tsam, cov thoob dej yug ntses, thiab txawm tias "iav" nyob ib puag ncig cov chaw ua si hockey. Acrylics kuj pom muaj nyob rau hauv cov tshuaj niaj hnub no, suav nrog cov khoom sib txuas, kev hloov cataract, thiab kev cog hniav. Koj lub tsev feem ntau yuav puv nrog iav acrylic: LCD cov ntxaij vab tshaus, cov iav uas tsis tawg, cov thav duab, cov khoom plig, cov khoom dai kom zoo nkauj, cov khoom ua si, thiab cov rooj tog feem ntau yog ua los ntawm iav acrylic.

Txij li thaum nws tsim los, acrylic iav tau ua pov thawj tias nws yog ib qho kev xaiv pheej yig thiab ruaj khov rau ntau daim ntawv thov.

Tau ntau tshaj 20 xyoo, DHUA tau ua tus thawj coj tsim cov ntawv acrylic thiab daim iav acrylic. Lub tswv yim ua lag luam ntawm DHUA tseem zoo ib yam - muab cov khoom siv kho qhov muag thoob ntiaj teb rau cov neeg siv khoom siab. Tiv tauj DHUA hnub no kom paub ntau ntxiv txog lawv cov khoom acrylic, cov thev naus laus zis tsim khoom, thiab cov kev pabcuam tshwj xeeb rau koj cov kev xav tau acrylic.
