Cov kev pabcuam yog: lub rooj sibthaum, lub rooj sibthiab, lub rooj tsavxwm dawb, lub rooj tsavxwm xim;
Cov Rooj Tswjfwm Tshwj Xeeb: Chav dej teeb meem, huab cua teeb meem, daim iav panels, daim ntaub nplaum daim txiag, lub rooj tsav tsheb, kev teeb tsa kev kub nyhiab, lub teeb ua haujlwm uas tsis muaj zog, lub qauv ntsa tawv, lub teeb daim txiag, lub teeb rooj rau cov hlau.
Txawv kev ua yeeb yam, txawv xim thiab kev pom kev zoo los ua kom tau raws li cov cai uas yuav tsum tau hloov.
1, Acrylic board Raws li cov txheej txheem ntawm cov txheej txheem cam khwb cia thiab cov phaj extruded, raws li cov teeb ntawm daim nplaum yuav muab faib ua cov pob tshab, txhais cov lus (nrog rau pob zeb pleev xim), xim xim (nrog rau xim dub thiab dawb thiab xim xim); Cov neeg ua haujlwm tiv thaiv, kev tswj hwm teeb meem, kev tswj hwm, kev teeb tsa kev tswj hwm, lub rooj teeb tsa kev sib tw, lub rooj teeb tsa kev ua haujlwm, kev teeb tsa kev ua kom muaj teeb meem.
A: Casting Board: siab moj khaum loj, zoo heev nruj, lub zog thiab tshuaj lom neeg kuj ua haujlwm zoo. Qhov twg yog qhov tsim nyog rau cov zauv loj ua cov quav hniav, qhov muag ntsig txog lub sij hawm ntev me ntsis. Daim ntawv no yog cov uas tsis muaj qhov ua kom tsawg, unmatched yooj yooj yim hauv cov xim system thiab cov duab zoo nkauj, thiab ua kom tiav cov khoom siv rau kev siv rau ntau yam kev siv tshwj xeeb.
B: Nyuaj pawg: Sib piv nrog cov phaj sib tw, nyem cov phaj qis dua qhov hnyav molecular, weaker mechanical zog, yooj ntau. Txawm li cas los xij, qhov no yog qhov yooj yim rau txoj kev siv tho kev thermoforming, nrog rau lub sij hawm luv luv softening. Hauv kev soj ntsuam nrog qhov loj ntawm lub phaj, yog qhov ua kom ntau yam ceev nqus. Nyob rau tib lub sij hawm, lub thickness siab ntawm lub extruded phaj yog me dua lub phaj cam khwb cia. Raws li cov phom extrusion yog huab cua ntau lawm, txa tau xim thiab loj me me, vim li ntawd qhov ntau hom khoom specifications raug rau qee yam kev txwv.
2, muaj ib hom acrylic rov qab rau lub rooj tsavxwm yog hu ua cov khoom siv coj los siv kho cov acrylic seem, tom qab thermal degradation ntawm MMA (methyl methacrylate) monomer, thiab tom qab ntawd los ntawm tshuaj polymerization muab pov tseg. Tom qab ib txoj kev tsis zoo, koj tuaj yeem rov ua haujlwm tau zoo dua MMA monomer, nrog lub tshuab hluavtaws tshiab, tsis muaj qhov sib txawv zoo. Txawm li cas los, qhov degradation monomer tsim, purity tsis siab, sheet hlau taus, nws zoo, kev kawm yog pluag.
Daim ntawv qhia: Cov phom extrusion yog ua los ntawm cov khoom siv pelletized thiab yog extruded tom qab raug yaj ntawm kub. Cov phom cast yog ncaj qha molded nrog MMA monomer (kua xeev). Txawm hais tias tus puab ntawm cov phaj extruded yog kuj du thiab du, Mus ua kom tiav cov polymerization. Thaum ua tiav rau hauv hlau, nws cov qauv thiab kev ua haujlwm tsis muaj zog thiab tsis haum raws li cov khoom siv rau sab nraum zoov cov khoom. Nws tsuas yog tsim rau cov khoom nyob sab hauv tsev xws li siv lead ua cim lossis khoom txhawb nqa.
Tsis tas li ntawd, feem ntau ntawm cov phom compression tsis muaj anti-UV muaj nuj nqi, lub neej ntawm nws siv sab nraum zoov thiab pouring phaj yuav tsis zoo li qub, xim yuav ploj thiab yooj yim embrittled, kom txog thaum lub rupture. Casting phaj nyob rau hauv lub phaj ua txheej txheem los ua kom tiav cov qauv ntawm polymerization, thaum twg UV absorbers, nrog siab siv thiab UV muaj nuj nqi, sab nraum zoov lub neej txog li 5 xyoos los yog 10 xyoo, kev siv cov xim tau ci li tshiab.
