Txhawm rau kom tau raws li cov kev xav tau ntawm cov khoom siv kom zoo nkauj
Cov khoom siv muaj txiaj ntsig zoo yog qhov zoo rau cov ntim khoom kom zoo nkauj ntim khoom. Tab sis muaj ntau cov neeg dog dig yog qee zaum tsis meej pem, tsis meej pem nruab nrab ntawm lawv thaum kawg qhov txawv, thaum kawg, tsis yog tib yam khoom.
Coob leej ntau tus muaj lus nug txog cov neeg siv acrylic feem ntau. Zoo li iav ntawm qhov deb, tab sis zoo li yas thaum ua ib qho zoo. Nws yog hu ua acrylic, puas yog iav lossis yas?
Dab tsi yog acrylic
Acrylic yog lub npe feem ntau rau cov khoom siv organic, lub npe Askiv yog polymathy metharate. Cov tsiaj ntawv yog PMMA, nws lub npe tag nrho yog hu ua polymathy metharacine, nws cov khoom siv raw yog rau acrylic tshuaj.
Feem ntau, peb tuaj yeem hnov lub npe ntawm cov paj rwb acrylic, acrylic xov, Acrylic Nylon thiab lwm yam ntxiv rau kev siv cov ntaub acrylic. Acrylic daim ntawv yog ua los ntawm acrylic hais thiab cob thiab lwm cov khoom siv hluav taws xob, thaum lwm cov acrylic textiles yog ua los ntawm acrylic textiles, lawv tsis koom nrog tib pawg.
Ntau lub sijhawm peb xav tias acrylic yog cov khoom siv tshiab, tab sis nws tau tsim rau ntau tshaj ib puas xyoo. Thaum ntxov li 1872, cov tshuaj polymer no tau nrhiav pom. Txog thaum 1920 thawj daim ntawv acrylic tau synthesized nkaus xwb hauv chav kuaj. Lub Hoobkas ua tiav kev tsim kho acrylic hauv xyoo 1927. Thawj tus tsim acrylic tsuas yog siv nyob rau hauv dav hlau. Qhov kawg ntawm lub xyoo pua 20, nrog kev txhim kho thiab kev vam meej ntawm cov txheej txheem ntau lawm, acrylic pib tau dav siv nyob rau hauv ntau kev lag luam. Nrog rau kev xav ntawm lub teeb, tsim tau kom zoo nkauj pleev xim acrylic hwj ci ntsa iab li lub pob zeb diamond.
Tam sim no, Acrylic tau dhau los ua cov khoom tseem ceeb rau ntau qhov kev lag luam, xws li cov khoom siv tshuaj pleev ib yam, ntsuas hluav taws xob, cov tawv ncauj tsheb, pob tshab thiab khoom siv tes ua.
Cov yam ntxwv ntawm Acrylic
Acrylic muaj siab transparency, ntshiab lub zeem muag, muaj peev xwm ncav cuag ntau dua 92% lub teeb xa tawm ntawm cov iav zoo tib yam tsuas yog kwv yees li 85%. Nws tuaj yeem ncav cuag cov pob tshab ntawm cov iav kho qhov muag, txawm hais tias zas qhov ua kom muaj qhov ua kom zoo nkauj ntawm acrylic. Cov kev xa nyiaj ntawm acrylic pab ua kom muaj ntau ci ci cos rau cov raj tshuaj cosmic & jars.
Ua tsaug rau cov khoom tshwj xeeb, lub zog ntawm acrylic yog ntau tshaj li kaum os lub sij hawm uas ntawm iav dog dig. Acrylic tuaj yeem piav nrog cov kab lus muaj zog sib piv rau cov iav zoo tib yam. Cov khoom lag luam ua los ntawm cov tshuaj acrylic yuav ua kom ruaj khov heev. Cov khoom pob tshab yog kom yooj yim rau kev khawb. Vim nws lub zog siab, Acrylic tseem yog ib qho ntawm cov hnav-resistant cov ntaub ntawv pob tshab.
Acrylic pib muag muag thaum 113 ℃, melting ntawm 160 ℃. Qhov kub no ua rau nws yooj yim heev, nws tuaj yeem ua rau hauv cov duab yooj yim.
Acrylic yog heev tiv taus hloov pauv qhov kub, av noo, acid thiab alkline, ua rau nws haum haum rau kev siv sab nraum zoov.
Txawm hais tias acrylic muaj ntau yam zoo, tab sis nws tseem muaj qee qhov tsis zoo. Thawj tus nqi, Acrylic yog kim dua iav, nws yog qhov nyuaj los hloov lub khob kom tiav. Thib ob, vim tias nws qhov chaw nres qis qis, acrylic thaum muaj nplaim taws yuav yaj thiab thaum kawg hlawv. Hlawv Acrylic yuav tso cov tshuaj lom neeg lom, yog li thaum nws txiav los ntawm cov cuab yeej hluav taws xob, nws yuav nyob rau hauv kub thiab txias thiab khoov.
Zoo li iav tab sis zoo li yas
Acrylic belongs rau cov polymerized polymer cov khoom, uas yog thermoplastic. Yog lawm, koj nyeem qhov tseeb, nws yog yas.
Acrylic yog ua los ntawm monomeric methyl methacrylate polymerization, yog li dab tsi txawv ntawm acrylic thiab lwm yam plastics?
Vim muaj ntau yam ntxwv zoo sib xws thiab iav, qee qhov zoo dhau lub khob, thiab qee qhov zoo tuaj yeem ua tiav rau kev ua tsis tau zoo ntawm iav.
Cov ntaub ntawv pob tshab yog ib qho ntawm cov khoom siv uas nquag siv nyob rau ntau yam kev lag luam, thiab cov tsim qauv tsim thiab cov tshuab luam yeeb feem ntau yog qhov kev xaiv thaum ib txwm muaj hnyav lossis tawg yooj yim heev.
Acrylic tshwm sim kom muaj cov khoom no ntawm iav lossis pob tshab cov khoom, tab sis nws tsis yog iav, yog li nws tau raug hu ua PlexigLass.
Txheej Txheem Txheej Txheem Acrylic Ntau Lawm
Cov txheej txheem ntau lawm ntawm acrylic zoo li ntawm lwm cov yas, tshwj tsis yog tias qhov tshwj xeeb kub thiab catalyst ntxiv yuav txawv.
Nrum moulding
Casting yuav tsum muaj pwm, molten acrylic yog hliv rau hauv cov pwm thiab sab laug tau muab tshem tawm cov pwm.
Tom qab daim ntawv tawm cov pwm, nws pauv mus rau ib qho autoclave, lub tshuab tshwj xeeb uas ua haujlwm zoo sib xws rau lub siab cooker thiab qhov cub. Lub autoclave siv cua sov thiab lub siab kom nyem cov yas tawm ntawm cov yas, muab nws lub zog siab dua thiab muaj zog dua siv sijhawm ntau teev.
Tom qab tshem tawm cov acrylic los ntawm autoclave, qhov chaw thiab cov npoo yuav tsum tau polishes nplej ntawm cov xuab zeb thiab tom qab ntawd nrog cov mos mos du thiab ntshiab acrylic nto.
Txiav tawm moulding
Cov khoom siv acrylic pellet raw yog ntxiv rau cov khoom siv extrusion kom txog thaum nws mus txog 150 ° C thiab tso cai rau nws los ua viscous.
Tom qab ntawd nws tau muab pub ntawm ob cov menyuam presses, thiab molten yas yog pluav los ntawm kev siab rau hauv daim ntawv tso rau hauv ib daim ntawv hnav khaub ncaws hnav thiab ua kom tawv.
Cov ntawv yog txiav rau qhov loj me thiab npaj txhij rau kev siv tom qab sib tsoo thiab polishing. Extrusion molding muaj peev xwm tsuas yog nias tawm cov ntawv tais tawm ntawm cov ntawv lossis cov nplooj ntawv tuab.
Txhaj Tshuaj Molding
Zoo li lwm cov khoom lag luam yas ntawm cov txheej txheem pwm kev txhaj tshuaj kuj tso moulding lossis cov ntsia hlau acrylic lossis cov ntsia hlau acryts rau hauv lub tshuab nqus dej lossis kub yaj lub raw khoom rau hauv ib tug paste.
Tom qab ntawd cov ntaub ntawv tau txhaj rau kev npau suav kab noj hniav thiab zoo li tus duab ruaj tom qab ziab los ntawm cov cua kub cua kub ntawm huab cua kub tom qab sib tsoo thiab sib txhuam.
Niaj hnub no, kev siv Acrylic tau nce qib zuj zus xyoo los ntawm lub xyoo. Txawm hais tias acrylic yog ib qho ntawm cov huab cua txawv tshaj plaws hauv kev siv hnub no, nws kho qhov muag qhib chaw ua rau ntau qhov kev xaiv sab nraud rau ntau cov ntawv thov kev lag luam zoo li ntim khoom.
