Acrylic Risers iav lwm yam khoom siv
Polymethylmethacrylate (hu ua PMMA, Lus Askiv Acrylic), tseem hu ua acrylic los yog lub ntsiab lus ntawm lub ntsej muag, nyob rau hauv Hong Kong thiab ntau lub npe hu ua Aga kua nplaum, nrog siab siab, tsis tshua muaj nqi, yooj yim ua haujlwm, lwm yam. . Lub monomer ntawm polymethylmethacrylate yog methyl methacrylate (MMA, acrylic monomer).
Acrylic tshuaj hu ua polymethyl methacrylate, hauv chav sov yog tsis muaj kuab lom, qhov saj ntawm qhov kev txiav thaum cov tshuaj tsw-meej, feem ntau tsis hnov tsw yuav ua rau tib neeg lub ntsej muag, yog lom tiam sis tsis tshua muaj kuab lom. Thaum lub ntsuas kub tshaj 130-140 ° C, qhov tshuaj lom neeg yuav ua rau cov roj acrylic mus hlawv thiab tsim cov pa phem.
Yuav kom siv cov tshuaj acrylic zoo, peb yuav tsum nco qab cov nram qab no:
1 tsis tuaj yeem muab nrog lwm cov organic solvents, tab sis tsis tuaj yeem hu rau cov organic solvents
2 Thaum caij tsheb thauj, daim ntaub thaiv qhov chaw tiv thaiv lossis daim ntawv tiv thaiv tsis tuaj yeem raug khawb
3 tsis tuaj yeem siv rau hauv cov cheeb tsam uas kub npaum li 85 degrees Celsius. Ntawm chav kawm, thaum lub ntsuas kub tshaj 130-140 ° C, nyob rau hauv rooj plaub ntawm aerobic rau lwm qhov teeb meem, nws yuav ua si ib fab tshuaj. Thaum peb kawm lub tsev kawm ntawv qib siab, yog li qhov yuav ua rau muaj kev kub ntxhov txuam nrog cov roj acrylic, ces acrylic combustion yeej yuav tsim teeb meem. Kuv muaj qhov kev paub no. Peb lub Hoobkas tshwj xeeb hauv cov khoom siv acrylic, acrylic zaub muag zaub, thiab qee zaus yuav siv lub tshuab laser tshuab, txhua lub sijhawm los ntawm laser tshuab tshuab carved acrylic, ib txwm tsw tsw pungent saj. Qhov no yog cov roj acrylic tsis tag nrho cov combustion ntawm teeb meem roj cua. Yog li, thaum siv lub tshuab laser engraving, lub qhov rooj thiab lub qhov rais yuav tsum qhib thiab cia rau hauv lub xeev qhov chaw. Tshwj xeeb tshaj yog nyob rau lub caij ntuj no, tsis txhob kaw qhov rooj thiab lub qhov rais, yuav tsum tsis txhob qhib cua txias.
4 ntxuav acrylic cov khoom tsuas yog 1% ntawm cov dej npum, nrog rau ib daim ntaub paj rwb mos mos hauv xab npum thiab dej, tsis tuaj yeem siv zog los yog qhuav txhuam, txwv tsis pub lub nplhaib yooj yim. Acrylic (methyl methacrylate) ntxiv rau cov tshuaj polymerization yuav ua PMMA thiab acrylic daim ntawv rau cov chaw ua qoob loo ua cov khoom tiav, tab sis kuj thiab ntau yam ntawm lwm yam monomer raw khoom ntawm copolymer (Co-polymers), Cov kua hom ntawm ntau yam kev siv ntawm cov khoom siv, siv cov khoom hauv qab no:
· PVC modifier (MBS): siv los txhawm rau txhim kho tej yam kuj ntawm PVC thiab kev ua haujlwm.
Xim: acrylic resin xim yuav muab faib ua oily, dej-raws ob pawg, siv rau sab hauv tsev thiab sab nraum zoov lub nrag xim thiab hlau, ntoo, yas thiab lwm yam xim muaj xim.
Adhesive: muab faib ua ob hom kev sib raug zoo thiab tsis tuaj yeem. Acrylic acoustic nplaum yuav siv tau rau cov ntawv, daim kab xev, cov ntaub ntawv pov hwm, cov ntaub ntawv pov tseg, phais caj dab, ntawv ntiv tes xuv xim, ntaub pua plag, N lub sij hawm nplaum ntawv, khau thiab lwm yam. Cov tawv nqaij tsis muaj qhov muag nplaum yuav siv tau rau ntawv, ntaub haum, muag, tsev nrog cov tshuaj muab tshuaj.
· Tus neeg saib xyuas kev txhim kho cov khoom siv: yuav siv tau rau cov khoom tsis-khaus, kev muag khoom, luam ntawv thiab dyeing, muab tshuaj thiab ua tiav.
· Tus neeg saib xyuas teeb pom kev zoo ntawm lub teeb thiab daim ntawv xa tawm: UV tawv tawv qhwv rau tus ciaj hlau rau ntau qhov, yuav ua kom lub ntsej muag gloss ntawm cov ntawv luam tawm, ua kom pom qhov zoo dua thiab muaj kev nkag siab siab, nce qhov teeb meem hnav thiab khaus ua haujlwm.
