Cov qauv niaj hnub hauv kev tsim kho thoob dej yug ntses yog kev hloov pauv ntawm cov iav iav nrog cov acrylic panels. Qhov kev hloov no feem ntau yog tsav los ntawm acrylic cov txiaj ntsig tseem ceeb hauv kev ua haujlwm kho qhov muag, kev ua haujlwm ncaj ncees, thiab kev tsim khoom yooj yim. Cov pab pawg engineering hauv cov zaub thiab thoob dej yug ntses kev lag luam tau sau cov ntaub ntawv dav dav, lees paub tias polymethyl methacrylate (PMMA, feem ntau hu ua acrylic) ua tau zoo heev hauv cov ntawv thov xws li hauv tsev ntses tso tsheb hlau luam mus rau cov thoob dej yug ntses loj.
iav vs. Acrylic
Qhov sib txawv ntawm ob cov ntaub ntawv no tseem ceeb tshwm sim los ntawm qhov sib txawv ntawm cov tshuaj inorganic thiab organic. iav yog silicate (cov tshuaj formula Na₂O·CaO·6SiO₂) uas yuav tsum tau melting thiab sib sau ntawm 1700 degree; acrylic, scientifically hu ua polymethyl methacrylate (PMMA), muaj cov mis molecular CH₂=C(CH₃)COOCH₃ thiab tuaj yeem tsim los ntawm kev siv petrochemical los ntawm polymerization ntawm chav tsev kub.
Ob qhov txheej txheem sib txawv no txiav txim siab lawv cov yam ntxwv hauv kev siv thoob dej yug ntses.
Lub teeb kis tau tus mob thiab Thickness
Txhua tus neeg uas tau tsim cov tso tsheb hlau luam loj paub tias cov vaj huam sib luag nyias yooj yim rau leej twg los ua pob tshab, tab sis cov tuab tuab tiag tiag qhia qhov sib txawv.
Cov ntaub ntawv xeem tiag tiag: Acrylic pom lub teeb xa tawm tseem nyob ruaj khov ntawm thaj tsam 92%. Daim duab no nws tus kheej tsis yog qhov tseem ceeb, tab sis qhov zoo tshaj plaws yog -peb tau tsim lub qhov rais 1.2-meter-thick saib lub qhov rais rau lub oceanarium hauv Zhuhai, thiab cov neeg tuaj saib sab nraum saib ntses taub ntswg ntev pom tsis muaj kev cuam tshuam ntawm ntug. Nyob rau hauv tib yam mob nrog iav? Nws pib tig ntsuab tshaj 15 cm, thiab ntawm 30 cm nws yeej zoo li ib tug watercolor painting.
Cov ntsiab lus ntau tus neeg tsis paub: Acrylic's UV transmittance yog li 73%, thaum iav zoo tib yam tsuas yog 0.6%. Cov cuab yeej no nyob ntawm qhov xwm txheej- rau khaws cov corals, anemones, thiab lwm yam kab mob uas yuav tsum tau tshwj xeeb spectra, nws yuav yog qhov zoo dua; tab sis rau cog cov tso dej tshiab, qhov cuam tshuam ntawm UV ntawm algae xav tau kev saib xyuas ntxiv.
Qhov hnyav thiab Engineering nqi sib txawv
Acrylic ceev yog 1.18-1.19 kg / dm³, kwv yees li ib nrab ntawm cov iav ntawm tib cov lus qhia.
Cov duab no zoo li tsis zoo, tab sis cov neeg uas tau ua tiav cov haujlwm engineering nkag siab tias qhov hnyav li cas ib nrab txhais tau tias: cov nqi tsheb thauj mus los raug txiav ib nrab, cov khoom siv hoisting tuaj yeem raug txo qis, cov khoom siv hlau tau txais kev cawmdim, thiab cov kev xav tau ntawm lub hauv paus tau so. Xyoo tas los, peb tau tsim lub thoob dej yug ntses rau thaj chaw ua lag luam hauv Chengdu- yog tias nws tsis yog rau acrylic, pem teb slab nyob rau hauv qhov chaw tsuas yog tsis tso cai.
Lwm qhov tshwj xeeb tshaj yog daim ntawv thov scenario: kev nthuav qhia ib ntus thiab ncig xyuas cov haujlwm. Rau cov haujlwm uas feem ntau txav mus los, lub teeb yog qhov tsim tau.
Kev lag luam tub rog tau txheeb xyuas qhov cuam tshuam tsis zoo
Acrylic tuaj yeem ua tiav qhov hnyav molecular mus txog 2 lab, thiab lub zog los ntawm nws qhov ntev - saw hlau yog qhov tseem ceeb. Lab cov ntaub ntawv qhia tias qhov cuam tshuam lub zog yog 7-18 npaug ntawm cov iav zoo tib yam ntawm tib lub thickness.
Ib me ntsis - paub qhov tseeb: Ntau lub dav hlau dav hlau canopies thiab cov iav tsis muaj phom siv cov acrylic stretched. Cov khoom no muaj cov cuab yeej tshwj xeeb- thaum nkag los ntawm lub mos txwv, nws tsis tawg mus rau hauv cov khoom tawg thiab ua rau neeg raug mob; cov khoom nyob ib ncig ntawm qhov kev ua txhaum cai tswj kev ncaj ncees. Cov thoob dej yug ntses pej xeem tsis xav tau qhov xwm txheej loj, tab sis rau qhov pom loj hauv cov chaw pej xeem, qhov kev nyab xeeb no yog qhov tiag.
Tus Qauv Tsim
Aquarium engineering boils mus rau ib yam: tswj dej siab.
Cov mis hydrostatic siab P=ρgh yog qhia nyob rau hauv lub tsev kawm ntawv theem nrab physics, tab sis nyob rau hauv kev xyaum, muaj ntau yam ntxiv los xav txog. Yuav ua li cas txiav txim siab vaj huam sib luag thickness? Cov txheej txheem kev lag luam yog suav cov theoretical yam tsawg kawg nkaus thiab tom qab ntawd muab faib los ntawm kev nyab xeeb ntawm 4-6. Yog vim li cas ib tug loj margin? Cov khoom sib txawv ntawm cov khoom sib txawv, kev nkag mus ntev, kev thauj khoom tsis txaus siab (xws li cov menyuam yaus tsoo rau hauv nws lossis cov ntxhua khaub ncaws nkag rau ntawm ntug) txhua yam yuav tsum tau suav rau.
Dej qhov tob ntawm 70 cm yog ib tug watershed
Rau cov pa hauv tsev thiab cov thoob dej yug ntses ua lag luam, peb feem ntau pom zoo kom khaws cov dej tob hauv qab 70 cm. Nws tsis yog qhov tob tob ua tsis tau, tab sis dhau qhov pib no, vaj huam sib luag thickness thiab thav duab lub zog yuav tsum tau nce siab, thiab tus nqi nkhaus dhau los ua ntxhab heev.
Kuj tseem muaj qhov teeb meem tshwm sim: cov tso tsheb hlau luam sib sib zog nqus yog qhov nyuaj rau cog. Lub teeb attenuates ho hauv dej, ua rau nws nyuaj rau cov nroj tsuag hauv qab kom tau txais photosynthesis txaus. Tshwj tsis yog siv cov teeb pom kev zoo hlau halide lossis siab - lub zog LEDs, qhov qis dua yog qhov pib cog cog zoo nkauj xwb.
Vaj Huam Sib Luag Thickness Ceev Reference
LUB SIJ HAWM
Ntev hauv qab 80 cm: 10-12 mm yog txaus.
MEDIUM
150-180 cm ntau: pom zoo 15-19 mm.
Loj
180 cm thiab mus txog 3.5 meters: yam tsawg kawg yog 22 hli los pib, nrog lub siab ruaj khov strips ntawm cov npoo nyiam los faib kev ntxhov siab.
Cov nuj nqis no los ntawm peb pab pawg tau txais kev paub dhau los ntau xyoo ntawm cov haujlwm; cov kev tshwj xeeb tseem xav tau zoo- kho raws li qhov tob dej, seb puas muaj lub hau npog, txoj kev teeb tsa, thiab lwm yam.
Base Txee Flatness yog lub neej
Peb tau pom ntau qhov ua tsis tiav. Lub tank nws tus kheej zoo, tab sis tom qab peb lub hlis nyob rau hauv qhov chaw, nws tawg -raws li kev tshawb nrhiav, lub hauv paus txee tsis sib xws.
Acrylic tsis nruj li iav thiab muaj peev xwm deformation, tab sis qhov no hloov mus ua ib qho kev phom sij zais. Yog hais tias muaj ib lub zos protrusion nyob rau hauv qab, lub vaj huam sib luag yuav maj mam ua raws li qhov taw tes, kev ntxhov siab concentrates, thiab dhau sij hawm cov kab nrib pleb tshwm. Tam sim no rau tej yaam num, lub hauv paus txee txais yuav tsum dhau ib theem kuaj; yog hais tias yuam kev tshaj spec, rework ncaj qha.
Lwm nthuav dav: txee qhov siab. Qhov zoo tshaj plaws saib txoj hauj lwm yog thaum cov dej saum npoo yog theem nrog sawv qhov muag qhov siab; xam txee qhov siab rov qab los ntawm qhov siab tank -qhov no yuav tsum tau xam ua ntej.
Cov txheej txheem ua haujlwm
Qhov zoo ntawm acrylic thoob dej yug ntses nyob ntawm 80% nyob rau theem ua. Cov ntaub ntawv tib yam hauv cov tes sib txawv tuaj yeem tsim cov txiaj ntsig sib txawv.
Cast Sheet vs. Extruded Sheet
Acrylic ntawv ntau lawm muaj ob txoj kev. Cov nplooj ntawv cam khwb cia yog polymerized los ntawm monomer ntawm ob lub iav polished, uas ua rau muaj kev sib xyaw molecular thiab kev ua haujlwm zoo tshaj plaws; Cov nplooj ntawv extruded yog yaj thiab nias los ntawm kev tuag, pheej yig dua tab sis nrog kev sib kis tsis zoo thiab kev ruaj ntseg.
Rau kev siv thoob dej yug ntses, tshwj xeeb tshaj yog rau cov haujlwm loj me ntsis, kuv qhov kev pom zoo yog xaiv ncaj qha rau cov ntawv cam khwb cia. Tus nqi sib txawv kis thoob plaws tag nrho qhov project yog qhov tsis txaus ntseeg, tab sis qhov sib txawv ntawm qhov muag pom tau pom ntawm qhov muag.
Txiav
Laser txiav muab siab precision thiab du npoo, feem ntau tshem tawm tom qab polishing. Tab sis lub hwj chim thiab ceev yuav tsum tau kho kom raug- qeeb heev kub kub ntawm ntug daj, ceev heev tsis hla. CNC engraving tshuab haum qhov tsis xwm yeem thiab cov txheej txheem slotted; programming yog tedious upfront tab sis cov zis yog ruaj khov. Tsoos sawing yog pheej yig tshaj, tag nrho txaus rau kev txiav ncaj, txawm tias burrs xav tau kev tuav ntxiv.
Kub Khoov
Acrylic softens nyob ib ncig ntawm 130 degree, tso cai rau nws yuav tsum tau nias tawm tsam pwm rau nkhaus los yog angled nto. Qhov no yog ib yam dab tsi iav ua tsis tau- iav nkhaus yuav tsum muaj lub qhov cub tawg, raug nqi ntau dua.
Tab sis kub dabtsi yog khoov muaj minefield: kub tswj. Hauv qab 125℃nws tsis yog mos txaus, yuam nws tsim kev ntxhov siab nrog rau yav tom ntej tawg; saum 140℃nws yooj yim yellows thiab ua nkig. Tom qab tshem tawm, nws yuav tsum txias rau 2-5 feeb ntawm 25-35℃ua ntej demolding; ceev txias yuav warp nws.
Polishing
Nplaim polishing yog ceev tshaj plaws, siv high - kub kub rau micro- melting nto rau tus kheej -leveling, haum rau txiav ntug; mechanical polishing nrog cov txheej txheem grit lub log muaj kev tswj zoo tshaj plaws; chemical polishing uses specific solvents to etch the surface for gloss, high skill threshold but top results. Zaub -qib cov khoom feem ntau muab cov khoom siv ua ke nrog cov tshuaj tiav.
Bonding
Kev koom nrog Acrylic tsis zoo li iav nrog silicone sealant, tab sis hnyav vuam -dichloromethane los yog cov nplaum tshwj xeeb ua rau cov chaw sib cuag, sib txuas ob daim ntawv ntawm qib molecular rau hauv ib qho. Ua tiav, lub zog ncav cuag 90% + ntawm cov khoom siv hauv paus; ua yuam kev, nws yog seem.
Qhov feem ntau tsis ua hauj lwm taw tes: tsis txaus deg tu. Ib tug ntiv tes, plua plav, los yog dej poob yuav tso cov cim mus tas li hauv cov seam. Peb txoj cai rhiav yog hnav cov hnab looj tes paj rwb ua ntej sib txuas, thiab so lub workbench nrog lint -dawb ntaub ntawm batches.
Tsis tas li ntawd, lub sijhawm kho. Cov ntawv tuab feem ntau xav tau 24+ teev ua ntej tsiv; rushing hnub kawg tua. Kuv tus kheej tau pom cov khoom xa tuaj tsuas yog 12 teev tom qab kev sib koom ua ke- pob ntawm txoj kev qhib tag nrho cov seams, tuaj txog ua pawg.
Daim ntawv tshuaj ntsuam xyuas zoo
Yuav ua li cas los txheeb xyuas cov khoom tiav tiav? Kos, impurities, kho qhov muag distortion, nto ripples, bonding npuas-tsis muaj leej twg yuav raug saib xyuas. Ua tib zoo saib xyuas tshwj xeeb rau cov cim shrinkage ntawm kaum sab xis, cov pob txha protrusions, micro- tawg -cov no feem ntau yog cov ntsiab lus kev ntxhov siab uas muaj teeb meem tshwm sim tom qab.
Ecosystem kev koom ua ke
Ntev - lub sij hawm khiav thoob dej yug ntses muaj lub tank accounting tsuas yog 30% ntawm kev siv zog; 70% yog nyob rau hauv cov cuab yeej txhawb nqa lub neej thiab cov chaw txhawb nqa.
Pom, ncig, tswj qhov kub thiab txias, teeb pom kev zoo -txhua qhov module xav tau qhov drilled hauv lub tank lossis cov interfaces tshwj tseg. Txhua lub qhov yog qhov muaj peev xwm muaj kev ntxhov siab thiab qhov kev pheej hmoo ntawm qhov xau, yog li txoj haujlwm thiab kev txhawb nqa yuav tsum tau npaj rau hauv theem tsim.
Ua siab dav nrog cov kav dej hla txoj kab uas hla. Peb kawm txog txoj kev nyuaj- ib qhov project loj dhau los ntawm kev xav tau ntws, tsis xav txog kev nce siab tom qab hluav taws xob rov pib dua; Thaum pib, nws overflowed lub tank. Tam sim no peb tus qauv yog 1.5 npaug ntawm qhov siab tshaj plaws.
Teeb pom kev zoo kuj xav tau kev saib xyuas. High-cov khoom siv hluav taws xob dai saum acrylic- yog tias kev tswj xyuas qhov kub tsis zoo, qhov kub thiab txias hauv cheeb tsam sib txawv ntawm lub vaj huam sib luag, uas yuav ua rau muaj kev puas tsuaj rau cov thermal kev puas tsuaj thaum lub sij hawm. Thiab tsis txhob hnov qab cov ntsiab lus dhau los-acrylic xa UV; thaum siv UV- muaj cov teeb, ntsuas qhov cuam tshuam rau cov neeg nyob hauv lub tank.
Hauv Kaw
Acrylic thoob dej yug ntses tsis siab - thev naus laus zis, tab sis ua kom lawv zoo yuav tsum tau txiav txim siab tshaj lij ntawm txhua kauj ruam. Cov khoom xaiv, tsim, ua, installation-slacking ntawm ib tug yuav rov qab los li leaks, tawg, los yog deformation.
Yog tias koj tab tom txiav txim siab txog kev cai acrylic thoob dej yug ntses, peb cov lus qhia yog: saib ob peb tus neeg muag khoom 'cov ntaub ntawv tiag tiag, nug kom meej tias cov ntaub ntawv siv dab tsi, cov txheej txheem kev sib txuas, thiab cov xwm txheej tshwj xeeb uas lub warranty npog. Cov tuam txhab ntseeg siab tsis ntshai cov lus nug ntxaws; ceev faj cov neeg uas tsuas hais tus nqi qis tab sis tsis tuaj yeem piav qhia cov ntsiab lus.
Xaiv tus khub zoo yog qhov pib rau kev vam meej hauv tej yaam num.
