Habka wax-soo-saarka xaashida birta dahaarka leh ee Al-Zn-cas-cas

2026,08,12

Codsiga Al-Zn Alloy Coating (Galvalume)
Gariiradda birta ah ee qabow-duuban waa la nadiifiyaa waxaana lagu dhejiyaa khad galvanizing kulul oo joogto ah. Ka dib waxaa lagu dhex quusiyaa qubeyska dhalada ah oo ka kooban ku dhawaad 55% aluminium, 43.4% zinc, iyo 1.6% silicon si loo sameeyo dahaadh isku mid ah oo Al-Zn ah. Gariiradda dahaarka leh ayaa hawo loo tolay si loo xakameeyo dhumucda daaha oo si degdeg ah loo qaboojiyo.

Dawaynta Hore ee Kiimikada iyo Diyaarinta Dusha sare
Gariiradda dahaarka leh ee Al-Zn waxa lagu daweeyaa kiimiko heerar badan leh. Tan caadi ahaan waxaa ka mid ah nadiifinta alkaline, luqluqashada, iyo codsiga daahan beddelka chromate ama chrome-free. Habkani waxa uu meesha ka saarayaa wasakhowga oogada oo waxa uu abuuraa falcelin isku mid ah, oogada u adkaysata daxalka oo leh sifooyin ku dheggan rinjiga.

Dahaarka koowaad iyo daawaynta
Qalab wax-qabad sare leh ee daxalka-horjooga ah (badanaa epoxy ama polyester-ku-saleysan) ayaa lagu dabaqaa dusha hore loo daaweeyay iyadoo la adeegsanayo jaakad rullaluisteed sax ah. Gariiraddu waxa ay soo martaa foornada wax lagu dawaynayo halkaas oo primer-ka lagu dubay heerkul la kantaroolay (tusaale, 200-230°C) si uu u sameeyo lakab cufan, dhegaysan, oo ilaalinaya.

Codsiga Koofiyadaha Sare ee Cas-khamriga iyo Xakamaynta Midabka/Qalabka
Koodh si gaar ah loo qaabeeyey oo-cas-cas ah (iyadoo la adeegsanayo polyester- cimri dheer, polyester silikoon ah, ama resins PVDF) ayaa lagu dul mariyaa curiyaha la daweeyay. Midabka horumarsan ee is waafajinta iyo nidaamyada xakamaynta wareegga-xiran waxay xaqiijinayaan joogteynta hadh saxda ah ee heerka bartilmaameedka khamriga-cas. Dahaarka ayaa markaa lagu daaweeyaa foornada labaad si loo gaaro dhalaalka la rabo (tusaale, matte ama dhalaalaya) iyo sifooyinka filimada.

Kormeerka ugu dambeeya, qaboojinta, iyo baakadaha ilaalinta
Ka dib marxaladda ugu dambeysa ee daaweynta, gariiradda ayaa la qaboojiyey si la xakameeyey. Waxa maraa baadhis adag oo la xidhiidha lebisnaanta midabka (iyadoo la isticmaalayo spectrophotometers), dhumucda dahaarka, adhesion (tijaabada iskutallaabta) iyo cilladaha dusha sare. Ugu dambeyntiina, filimka difaaca polyetylen (PE) ama polyester (PET) ayaa lagu dhejiyaa dusha sare ka hor inta aan gariiradda dib loo soo celin oo baakad loo soo rarin.
