Dhawaan, waxaan heleynaa baaritaan badan oo ka mid ah weydiimaha ku saabsan in lagu beddelo difaacdooda aadaysan ee acrylic old acrylic ee leh difaac gacmeed oo qabow.
Aynu sheegno waxa quraaradda loo qabto iyo PMMA marka hore sidii nooc kooban:
Waa maxay galaaska qabow?
Galaaska qaboojiyahaWaa nooc galaas badbaado ah oo lagu sameeyo daweynta kuleylka ama kiimikada lagu xakameeyo si loo kordhiyo xooggeeda marka la barbar dhigo galaaska caadiga ah.
Hurdadu waxay ku dhejisaa sagxadaha kore wixii ku dhexjira cadaadiska iyo gudaha xiisadda.
Waxay u gashataa dillaac yar yar oo granks ah halkii ay ka isticmaali lahaayeen baararka jahwareerka ah ee muraayadaha caadiga ah ee dhalaashaha ah oo aan lahayn wax dhaawac ah aadanaha.
Waxay inta badan khusaysaa alaabada elektiroonigga ah ee 3aad, dhismayaasha, gawaarida, iyo aagag kale oo badan.
Waa maxay PMMA?
Polytyl methacrylate (PWM), resin isku-dhafan oo laga soo saaray polymarization ee methyl methacrylate.
Caag hufan oo adag,PWMWaxaa badanaa loo isticmaalaa bedelka dhalada ee galaaska sida daaqadaha loo yaqaan 'strampof daaqadaha' stwareprof ', kuwa cirka leh, calaamadaha iftiinka leh, iyo bayoolajiyada diyaaradaha.
Waxaa lagu iibiyaa astaanta ganacsigaPlexiglas, Lucite, iyo dhageyste.
Waxay inta badan ku kala duwan yihiin dhinacyada hoose:
| Kala duwanaansho | 1.1mm Class Class | 1mm pmma |
| Hurdada Moh | ≥7h | Heerka 2h, ka dib markii la xoojiyay ≥4H |
| Ka gudbi | 87 ~ 90% | ≥91% |
| Cimri dherer | Iyadoo aan gabow & midab beeniyo been abuur ah kadib | Si fudud u hel gabow & hurdi |
| Kulaylka u adkaysta | Wuxuu qaadi karaa 280 ° C heerkul sare oo aan jabin | PMMA Bilow si ay u jilcaan marka 80 ° C |
| Taabashada Taabashada | Garan karaa shaqada taabashada & ilaalinta | Kaliya hayso shaqo ilaalin ah |
Kor ku xusan waxay si cad u muujineysaa faa iidada isticmaalka aIlaalinta GlassKa fiican kan ka fiican difaaca PMPA, waxaan rajeyneyaa inay gacan ka geysaneyso go'aanka dhawaan.
