Inferior PC polycarbonate ntawv tau muab faib ua pawg hauv qab no:
1. PC polycarbonate ntawv ua nrog polycarbonate reclaimed cov ntaub ntawv thiab cov ntaub ntawv siv dua
Cov ntawv polycarbonate uas tsim nrog PC reheating cov ntaub ntawv thiab cov khoom siv rov ua dua PC tau tawg cov tshuaj sib txuas ntawm cov molecules, kev sib koom ua ke ntawm cov molecular ntawm cov molecules thiab cov molecules, thiab cov khoom siv lub cev ntawm lub rooj tsavxwm kuj raug rhuav tshem, yog li PC Lub cev muaj zog ntawm cov khoom siv. board kuj raug rhuav tshem, thiab qhov cuam tshuam ntawm cov ntawv polycarbonate kuj raug puas tsuaj.Yog li ntawd, cov ntawv PC uas tsim los ntawm cov khoom siv rov ua dua tshiab muaj qhov tsis zoo cuam tshuam thiab yooj yim tawg (piv txwv li: thaum screwing, qhov drilling yog ib qho yooj yim tawg thiab xa rov qab cov khoom. Hollow polycarbonate ntawv uas ua tsis tau tsuas yog muaj kev cuam tshuam tsis zoo, tab sis kuj muaj tsis zoo pob tshab thiab yellowing ntawm board nto.

2. Siv cov khoom siv PC tshiab los tsim cov ntawv polycarbonate yam tsis tau ntxiv tus neeg saib xyuas los tiv thaiv UV
Hauv cov txheej txheem tsim khoom, peb tau siv PC brand-tshiab cov ntaub ntawv los tsim cov polycarbonate panels, tab sis lawv tsis ntxiv cov tshuaj tiv thaiv UV lossis ntxiv cov txheej txheem los tiv thaiv UV thaum lub sijhawm tsim khoom raws li cov kev xav tau ntawm cov txheej txheem, kom lub PC polycarbonate. daim ntawv tsim nyob rau hauv thawj 1-2 xyoo ntawm kev siv thaum ntxov, lub cev thiab tshuaj lub zog ntawm daim ntawv yuav tsis hloov ntau, tab sis nyob rau hauv lub tom ntej no 3-5 xyoo, cov tshuaj sab hauv thiab lub cev ntawm daim ntawv yuav hloov heev.Qhov laj thawj tseem ceeb yog vim li cas qhov ultraviolet (UV) ib feem ntawm lub teeb ua rau lub hnub nyoog ntawm cov ntawv yas polycarbonate, uas ua rau kev ua haujlwm ntawm cov ntawv polycarbonate poob qis (qhov pom kev pom tseem ceeb yog: yellowing, brittleness, shrinkage, thiab tawg ntawm Qhov saum npoo., Sab saum toj thiab hauv qab yog npog los ntawm cov khoom oxidizing uas tsim tom qab cua oxidation) Yog li ntawd, hollow polycarbonate ntawv siv sab nraum zoov yuav tsum nruj me ntsis raws li cov txheej txheem yuav tsum tau, ntxiv anti-ultraviolet UV txheej rau saum npoo ntawm daim ntawv PC, thiab Ntxiv cov tshuaj tiv thaiv ultraviolet rays rau PC daim ntawv substrate Yuav kom ntseeg tau lub neej kev pab cuam ntawm lub PC khoom ntawv, nyob rau hauv cov cheeb tsam uas muaj zog ultraviolet hluav taws xob, xws li Algeria, Saudi Arabia, Pakistan, Brazil, Philippines, Malaysia, Indonesia, nws yog tsim nyog. los kho qhov tsim cov ntawv polycarbonate raws li lub sijhawm nruab nrab ntawm lub hnub ci hauv zos thiab lub hnub ci siv (tsuas yog teeb tsa Thickness thiab concentration ntawm UV txheejntawm PC ntawv)
3. Tsis muaj cov khoom siv raw uas tsim nyog rau kev tsim cov txheej txheem PC polycarbonate extrusion tau raug xaiv
Cov txheej txheem ntawm cov ntaub ntawv yas yog muab faib ua: 1, extrusion 2, txhaj tshuaj molding 3, dripping 4, pouring 5, calendering, thiab lwm yam. Cov qauv kev xaiv cov ntaub ntawv rau txhua tus txheej txheem yog sib txawv kiag li, thiab cov polycarbonate yuav tsum tau xaiv raws li cov txheej txheem. daim teb ntawm cov khoom siv thiab cov txheej txheem ntau lawm.Extrusion-qib polycarbonate raw cov ntaub ntawv yog cov kim tshaj plaws ntawm tag nrho cov qib ntawm raw cov ntaub ntawv, thiab extrusion-qib raw cov ntaub ntawv yog subdivided raws li daim ntawv thov teb.Yog li ntawd, thaum xaiv cov ntaub ntawv raw rau PC daim ntawv ntau lawm, lawv yuav tsum tau xaiv raws li cov khoom ntawm raw cov ntaub ntawv es tsis yog tus nqi.
4. Siv cov ntaub ntawv tsis-polycarbonate los tsim (xws li: acrylic PMMA, PS ntawv, PP ntawv, thiab lwm yam)
Acrylic PMMA, PS ntawv, PP ntawv, thiab lwm yam yog inherently tsis huab cua resistant.Yog tias lawv yuav tsum muaj kev tiv thaiv kev laus, kev cuam tshuam thiab lwm yam khoom, lawv yuav tsum tau hloov kho los ntawm cov yas.Txawm li cas los xij, vim tias acrylic PMMA, PS daim ntawv, PP ntawv thiab lwm yam khoom siv raw khoom pheej yig, qee cov tuam txhab lossis cov neeg muag khoom siv acrylic PMMA, PS ntawv, PP ntawv thiab lwm yam khoom los ua tus neeg siv cov ntawv PC los dag cov neeg siv khoom thiab ua rau muaj kev puas tsuaj loj rau kev lag luam.
