Clear Vacuum forming Plastic Sheets

Lub tshuab nqus tsev tsim cov ntawv yas yog dav siv thoob plaws hauv kev lag luam xws li ntim khoom, tsheb, khoom siv kho mob, thiab cov khoom siv kho mob vim lawv qhov zoo tshaj plaws pob tshab, formability, thiab nto tiav. Ntawm cov no,ntshiab lub tshuab nqus tsev ua cov ntawv tuabcov ntaub ntawv-xws li pob tshab ABS daim ntawv, polycarbonate (PC) daim ntawv, thiab qee zaum acrylic (PMMA)-yog qhov zoo tagnrho rau cov khoom siv uas yuav tsum tau muaj kev cuam tshuam thiab pom qhov pom tseeb. Rau cov ntawv thov nyias nyias, cov ntawv ntshiab PVC thiab pob tshab polypropylene (PP) feem ntau xaiv rau lawv qhov yooj yim, tshuaj tiv thaiv, thiab tus nqi - ua tau zoo. Tsab ntawv xov xwm no tshawb txog cov txheej txheem kev tsim khoom tseem ceeb rau lub tshuab nqus tsev tsim cov ntawv yas, cov teeb meem ntau lawm, thiab cov ntsiab lus ntawm lub tshuab nqus tsev tsim cov txheej txheem.

Thawj Txoj Kev Tsim Nyog rau Nqus Nqus Ua Cov Ntawv Yas

Kev tsim cov tshuab nqus tsev tsim cov ntawv yas feem ntau pib nrog cov khoom siv raw polymer, uas tau hloov mus rau hauv cov ntawv tiaj tus, pob tshab siv ob peb txheej txheem extrusion lossis casting. Cov txheej txheem feem ntau muaj xws li:

a) Extrusion

Extrusion yog txoj kev tseem ceeb rau kev ua kom pom tseeb lub tshuab nqus tsev ua cov ntawv yas. Polymer pellets (xws li, ABS, PC, PVC, PP) yog melted nyob rau hauv ib tug ntsia hlau extruder thiab yuam los ntawm ib tug ca tuag los ua ib daim ntawv nruam. Cov ntawv yog tom qab ntawd polished los ntawm cov chrome -plated chill rolls kom ua tiav siab pob tshab thiab cov tuab tuab. Rauntshiab lub tshuab nqus tsev ua cov ntawv tuab(piv txwv li, 1.5 hli mus rau 10 hli lossis ntau dua), cov kab extrusion siv qhov sib txawv loj dua thiab ua kom txias dua kom muaj qhov pom tseeb tsis muaj kev ntxhov siab sab hauv. Cov nplooj ntawv nyias nyias (0.2-1.5 hli) zoo li cov PVC lossis PP yog tsim nrog cov kab nrawm dua thiab nyias qhov ntsuas calibration.

b) Calendering

Calendering yog siv rau cov ntaub ntawv ntshiab xws li PVC. Lub molten polymer kis tau los ntawm ntau cov rhuab chais uas compress thiab du cov khoom rau hauv cov ntaub ntawv pob tshab los yog daim ntawv. Txoj kev no muab qhov zoo tshaj plaws gloss thiab thickness precision, qhov tseem ceeb rau daim ntaub ntawv xws li blister ntim.

c) Casting (rau cov ntawv tshwj xeeb)

Rau qee cov thermoplastics xws li acrylic (PMMA) lossis polycarbonate, casting tuaj yeem tsim ultra-cov nplooj ntawv ntshiab nrog qhov cuam tshuam qhov muag tsawg. Cov kua monomer yog nchuav ntawm ob daim iav polished los yog mus rau ib txoj siv txuas ntxiv, ces polymerized. Cam khwb cia cov nplooj ntawv kim dua tab sis muaj kev pom zoo tshaj plaws thiab feem ntau siv rau siab -kawg lub tshuab nqus tsev daim ntawv thov (piv txwv li, lo ntsiab muag, tshuab tiv thaiv).

Cov teeb meem tshwm sim hauv kev tsim cov Nqus Tsev Nqus Tsev ua cov ntawv yas

Kev tsim lub tshuab nqus tsev ntshiab ua cov ntawv yas nthuav tawm cov kev sib tw tshwj xeeb, tshwj xeeb tshaj yog thaum kev pom tseeb yog qhov tseem ceeb. Cov teeb meem tseem ceeb muaj xws li:

a) Optical defects

Cov kab tuag, specks, lossis gels: Cov kab mob sib kis los yog cov khoom tsis zoo ntawm cov polymers ua rau pom qhov tsis xws luag. nruj raw khoom kom qhuav (xws li, PC thiab ABS yog hygroscopic) thiab lim mesh packs nyob rau hauv lub extruder yog qhov tseem ceeb.

Deg haze los yog txiv kab ntxwv tev: Tsis yog qhov txias txias los yog siab tuaj yeem tawm ntawm qhov tsis sib xws. Rauntshiab lub tshuab nqus tsev ua cov ntawv tuab, tuav qhov kub thiab txias hauv qhov nqaim (piv txwv li, 60-80℃rau PC) tiv thaiv micro-crystalization.

Internal stress thiab birefringence: Cov cua txias nrawm los yog qhov tuab tsis sib xws ua rau muaj kev ntxhov siab ntau ntxiv uas ua rau muaj kev kub ntxhov los yog cuam tshuam hauv qab cua sov thaum lub tshuab nqus tsev. Annealing (post- cua sov) tej zaum yuav xav tau rau cov ntawv tuab PC.

b) Dimensional stability

Cov ntawv tuab (piv txwv li, 5 hli ABS) zoo li ntsws tsis sib xws thaum lub caij txias. Siv lub tshuab nqus tsev sizing lub thawv lossis ntug-pinning tshuab ntawm kab extrusion pab tswj qhov dav thiab tuab. Nyias ntshiab PVC los yog PP nplooj ntawv tuaj yeem tsim cov npoo npoo (gauge bands) vim yog yaj ntws tsis ruaj khov.

c) Moisture rhiab heev

Cov ntaub ntawv zoo li PC, ABS, thiab PETG nqus dej noo los ntawm huab cua. Yog tias tsis ua ntej- qhuav (feem ntau 2-4 teev ntawm 80-120 degree), noo noo vaporizes thaum extrusion, tsim npuas (splay marks) uas rhuav tshem pob tshab. Kaw-voj drying hoppers yog tus qauv tsim los ua cov ntaub ntawv yas.

d) Nto khawb thiab kis kab mob

Cov nplooj ntawv ntshiab yog qhov cuam tshuam rau khawb los ntawm kev qhia yob lossis tuav. Plua plav lossis roj ntawm cov yob polishing tuaj yeem hloov qhov tsis xws luag. Ntau tus neeg tsim khoom siv cov yeeb yaj kiab tiv thaiv npog ntawm ob sab tam sim tom qab extrusion.

peb case

Tus tsim lub tshuab CNC xav tau kev tiv thaiv npog rau lawv qhov siab - router ceev kom muaj cov khib nyiab thiab cov dej txias thaum tso cai rau cov neeg ua haujlwm saib xyuas cov txheej txheem txiav hauv lub sijhawm. Lawv xaiv ibntshiab lub tshuab nqus tsev ua cov ntawv tuabntawm pob tshab ABS (3 hli) rau nws qhov sib npaug ntawm qhov tawv, khawb tsis kam, thiab tus nqi qis dua polycarbonate. Daim ntawv no yog nqus tau los ntawm qhov sib sib zog nqus-kos cov poj niam pwm nrog lub ntsaws pab tiv thaiv kom tsis txhob muaj ntau dhau ntawm cov ces kaum. Lub hau tsim muaj xws li cov pob khawm pob khawm thiab ib lub qhov rais pob tshab. Tom qab trimming thiab ntug tiav, lub hau yog mounted ntawm ceev - tso latches. Thaum lub sij hawm tsim khoom, cov chaw tsim khoom tau ntsib cov teeb meem me me vim qhov tsis sib xws ntawm cua sov; qhov no tau daws los ntawm kev ntxiv thaj tsam - tswj cov cua sov infrared. Qhov kawg ntawm ABS npog muab tag nrho pom kev, kev tiv thaiv zoo heev, thiab kev pabcuam lub neej tshaj 10,000 teev ua haujlwm, tag nrho ntawm 60% ntawm tus nqi ntawm cov khoom siv acrylic.

Lub chaw tsim khoom lub nkoj ua si xav tsim ob -tus neeg lub nkoj pob tshab rau kev ncig xyuas lub pas dej, tso cai rau cov neeg caij tsheb saib cov duab hauv qab dej ncaj qha los ntawm lub nkoj. Sivntshiab lub tshuab nqus tsev ua cov ntawv tuabua los ntawm polycarbonate (PC) - xaiv rau nws qhov tshwj xeeb cuam tshuam tsis kam, UV stability, thiab ze rau - iav clarity - lub tuam txhab nqus tsev tsim ob lub ntsiab hull halves (txhua 4 hli tuab). Cov txheej txheem koom nrog cua sov daim ntawv PC rau 210 degree, draping nws hla lub polished aluminium txiv neej pwm, thiab siv 28 inHg ntawm lub tshuab nqus tsev los xyuas kom meej txawm tias phab ntsa thickness thiab optical transparency. Tom qab txiav thiab khi cov halves nrog cov kuab tshuaj ntshiab, lub nkoj sib dhos hnyav tsuas yog 38 kg, tab sis tuaj yeem tiv taus qhov cuam tshuam rov qab los ntawm kev sib tsoo yam tsis muaj kev tawg. Qhov tshwm sim: lub cev ruaj khov, siv lead ua- lub nkoj ntshiab uas txhim kho cov neeg tuaj ncig tebchaws uasi thiab txo kev txij nkawm piv rau cov qauv siv fiberglass.
