Habka wax soo saarka ee gariiradda birta ku dahaaran fluorocarbon PVDF-cas-cas

Diyaarinta Gariiradda Birta iyo Dawaynta Kiimikada ka hor
Gariirad bir ah oo tayo sare leh oo qabow-duuban ama galvanized ayaa loo doortaa sida walxaha aasaasiga ah. Dusha gariiradda ayaa mareysa hannaan nadiifin kiimiko oo heerar badan leh oo ay ka mid yihiin xaalufinta alkaline, luqluqashada, iyo codsiga daahan beddelka chromate ama chrome-free si loo hubiyo nadaafadda ugu habboon iyo ku dheggan rinjiga ee lakabyada daahan ee xiga.

Codsiga koowaad iyo daaweynta kulaylka
Qalab wax qabad sarreeya oo daxal-hortaag ah (sida caadiga ah epoxy ama polyester-ku-saleysan) ayaa si isku mid ah loogu dabaqaa dusha hore loo daaweeyay iyadoo la adeegsanayo jaakad rullaluistu ah oo sax ah. Gariiradda dahaarka leh ayaa markaa soo marta foornada lagu dawaynayo kulaylka sareeyo halkaas oo rajada lagu dubay si uu u sameeyo lakab cufan, difaac ah, oo aadka u dhejisan.

PVDF Fluorocarbon Topcoat Formulation and Application
Koodhka sare ee fluorocarbon PVDF-cas ah oo si gaar ah loo qaabeeyey ayaa la diyaariyey, oo ka kooban saamiga sare (sida caadiga ah ≥70%) ee xabagta PVDF saafiga ah, midabada cas ee aan noolaha lahayn ee qaaliga ah (badanaa lagu daro oksaydhyo gaar ah oo loogu talagalay midabka khamriga-cas), iyo wax lagu daro xasilloonida UV iyo dabacsanaanta. Daahan waxa si sax ah loogu dul mariyaa lakabka hore ee la daweeyay iyadoo la isticmaalayo tignoolajiyada dahaarka rullaluistulayaasha horumarsan.

Daawaynta Heerkulka Sare iyo Samaynta Filimada
Gariiradda dahaarka leh waxay gashaa foornada lagu dawaynayo heerkul sare oo si sax ah loo xakameeyay. Kuleylku wuxuu dhalaaliyaa qaybaha xabagta PVDF, taasoo u oggolaanaysa inay qulqulaan oo ay sameeyaan filim joogto ah, xiriir sare leh, iyo kiimiko ahaan aan firfircoonayn. Habkani waxa uu muhiim u yahay horumarinta dahaarka cimilo ahaan gaar ahaaneed, haysashada dhaldhalaalka, iyo sifooyinka farsamada.

Hubinta Tayada kama dambaysta ah, Qaboojinta, iyo Xirmooyinka Ilaalinta
Ka dib marka la daweeyo, gariiradda ayaa lagu qaboojiyaa meel la xakameeyey. Waxay maraa kormeer tayo adag oo loogu talagalay saxnaanta midabka (iyadoo la adeegsanayo spectrophotometers), dhumucda dahaarka, adhesion (iyada oo la adeegsanayo tijaabooyinka is-goynta iyo leexinta), heerka dhalaalka, iyo cilladaha dusha sare. Ugu dambayntii, filimka polyetylen-ka la rari karo ee ilaalinaya (PE) ayaa lagu dhejiyay dusha ka hor inta aan gariiradda dib loo soo celin oo baakad lagu rarin.

Taxanaha alaabadayada waxaa ka mid ah PPGI/PPGL Birta loogu talagalay saqafka raagaya, Aluminium Prepainted leh iska caabin daxalka sare leh, Prepainted Stainless for bey'ada nadaafadda sare, Birta hadhuudhka ah ee daabacan oo ku ekaanaysa qurxinta alwaaxyada dabiiciga ah, Qaybaha Galvanized Steel ee sharafta qaabdhismeedka, Qaybaha aluminium ee qaybaha miisaanka fudud, qaybo kakan oo aan qallafsaneyn Saqafka saqafyada leh waxqabadka cimilada, Waraaqaha xayndaabka oo bixiya xuduudo sugan, Biraha birta oo loo habeeyay in lagu xidho isku halaynta, Qaybaha caadiga ah ee hubinaya isdhaafsiga, Qaybaha aan caadiga ahayn ee loogu talagalay nashqadaha gaarka ah, Saqafka birta oo leh cimri dheer, Nidaamyada derbiga daahyada ee wejiyada casriga ah, Deedka birta ee amniga iyo qaabka, Guriga Prefab oo leh nidaamyada biyaha ee degdega ah biyo-mareen hufan, iyo guddiyada gidaarka ee xidhidh la'aanta ah.
