Sharaxaada Alaabta
Faa'iidooyinka filimka xuubka unugyada qoraxda (EVA) ayaa lagu soo koobay sida soo socota:
1. Daah-furnaan sare iyo dhejis sare ayaa lagu dabaqi karaa is-dhexgalyo kala duwan, oo ay ku jiraan muraayadaha, birta iyo caagagga sida PET.
2. Adkeysiga wanaagsan wuxuu u adkeysan karaa heerkulka sare, qoyaanka, fallaadhaha ultraviolet iyo wixii la mid ah.
3. Si fudud loo kaydin karo. Lagu kaydiyo heerkulka qolka, ku dhejinta EVA ma saameeyaan qoyaanka iyo filimada nuugista.
4. Marka la barbar dhigo PVB, waxay leedahay saameyn xoog badan oo dahsoon, gaar ahaan saamaynta dhawaaqa ee soo noqnoqda.
5. Bar dhalaalaysa oo hooseeya, fudud oo qulqulaya, oo ku habboon habka laminating ee galaasyada kala duwan, sida muraayadaha naqshadaysan, muraayadda kulul, muraayadaha qalooca, iwm.
Filimka EVA waxa loo isticmaalaa sidii muraayadda la dahaadhay, kaas oo si buuxda u waafaqsan heerka qaran ee "GB9962-99" ee galaaska dahaadhay. Kuwa soo socdaa waa tusaale filim hufan oo dhumucdiisu tahay 0.38mm.
Tilmaamayaasha waxqabadku waa sida soo socota:
| Tusiyaha Mashruuca | |
| Xoog xajin (MPa) | ≥17 |
| Gudbinta iftiinka muuqda (%) | ≥87 |
| Kordhinta wakhtiga nasashada (%) | ≥650 |
| Heerka ceeryaamo (%) | 0.6 |
| Awood xidhidh (kg/cm) | ≥2 |

| Iska caabinta kulaylka dhaaf | |
| Iska caabinta qoyaanka ayaa u qalma | |
| Iska caabinta saamaynta ayaa u qalantay | |
| Waxqabadka saamaynta boorsada la toogtay U qalma | |
| Heerka goynta UV | 98.50% |
Waa maxay faa'iidooyinka iyo khasaaraha filimka baakadaha EVA?
Qaybta ugu muhiimsan ee filimka EVA waa EVA, oo lagu daray waxyaabo kala duwan, sida wakiilka iskutallaabta, dhumucda, antioxidant, xasilinta iftiinka, iwm. iska caabin iyo qiimo hoose. Laakiin cilladeeda PID sidoo kale waa caddahay.
Soo ifbaxa modules-ka laba-glaas ah waxay u muuqataa inay siinayso EVA suurtogalnimada inay ka gudubto cilladaha la taaban karo. Maaddaama heerka gudbinta uumiga biyuhu ee galaasku uu ku dhow yahay eber, biyo-mareenka hooseeya ee biyuhu ama eber-ka-qaadista biyaha ee modules-ka laba-glaas ah ayaa ka dhigaysa iska caabbinta EVA hydrolysis mar dambe dhibaato.
Fursadaha iyo caqabadaha filimada baakadaha POE
Waxaa laga soo saaray biraha birta ah, POE waa nooc cusub oo ah elastomer elastomer ah oo polyolefin ah oo leh qaybin cufan oo qaraabo ah, qaybin wadaag dhuuban iyo qaab dhismeed la xakamayn karo. POE waxa ay leedahay awood uumiga biyaha oo aad u fiican iyo awoodda caqabada ion. Heerka gudbinta uumiga biyuhu waa qiyaastii 1/8 ee EVA, habka gabowgana ma soo saaro walxo acidic ah. Waxay leedahay wax-qabad heersare ah oo ka-hortagga gabowga waana wax-ku-oolnimada sare iyo kalsoonida sare ee sawir-qaadista. Maaddada doorashada ee filimada encapsulation qayb.
Nidaamka quudinta gravimetric-ka tooska ah wuxuu hubinayaa kala duwanaanta adag, wax lagu daro dareeraha iyo alaabta ceeriin quudinta saxda ah. Nidaamyada ka saarista heerkulka-hooseeya si loo hubiyo isku-dhafka ku filan ee dhismaha dhoobada si looga hortago wax-is-weydaarsiga isku-dhafan. Naqshadaynta gaarka ah ee qayb kabka ayaa siinaya xalka ugu fiican ee xajinta rullaluistuyada iyo biya-baxa. Qalab gaar ah oo xamaasad leh oo khadka tooska ah si looga takhaluso diiqada gudaha. Nidaamka xakamaynta xiisadda ayaa hubiya in xaashida dabacsan ee u gudbinta si cad inta lagu jiro qaboojinta, jiidashada iyo habka dabaysha. Nidaamka cabbiraadda dhumucda khadka iyo nidaamka kormeerka cilladdu waxay bixin kartaa jawaab-celinta waqtiga-dhabta ah ee tayada wax soo saarka ee EVA / POE filimka qoraxda.
Filimka sawir-qaadista ee EVA/POE ayaa inta badan loo adeegsadaa soo-saarista qaybaha sawir-qaadista waana agabka muhiimka ah ee qaybaha sawir-qaadista; Waxa kale oo loo isticmaali karaa warshado kala duwan sida gidaarka muraayadda muraayadda, muraayadda baabuurta, xabagta dhalaalka kulul, iwm.
