Habka wax soo saarka ee matte adag xaashi bir galvanized midab madow-dahaarka leh

Diyaarinta Gariiradda Birta Galvanized Steel
Gariiradaha birta galvanized-kuleelka ah ee tayada sare leh leh miisaanka daahan zinc ee la cayimay (tusaale, Z275) ayaa loo xushay inay noqdaan walxaha aasaasiga ah. Dusha sare ee gariiradda ayaa lagu eegaa isku mid ahaanshaha iyo nadaafadda si loo hubiyo aasaaska cilladda leh ee habka daahan.

Dawaynta Kahor Kiimikada iyo Dhaqdhaqaaqa Dusha sare
Gariiraddu waxay dhex martaa khad kiimiko ah oo heerar badan leh oo ku lug leh xaalufinta alkaline, luqluqashada, kicinta dusha sare (tusaale, fosfitinta ama chromating), iyo biyo raacid ugu dambeeya oo fuuq-baxsan. Tani waxay abuurtaa nadiif isku mid ah, u adkaysata daxalka, iyo dusha sare ee dhejiska ee dahaarka xiga.

Codsiga koowaad iyo daawaynta
Epoxy-adhesion-ku-dheeraaday ama poliester primer ayaa si isku mid ah loogu dabaqayaa dusha hore loo daaweeyay iyadoo la isticmaalayo jaakad rullaluistu ah oo sax ah. Gariiradda dahaarka leh ayaa markaa gasha foornada lagu dawaynayo, halkaas oo asalka hore lagu dubay heerkul la kantaroolay (sida caadiga ah 200-220 ° C) si loo sameeyo lakab cufan oo difaac ah.

Codsiga Koofiyadaha Madow ee Adag iyo Xakamaynta Qoraalka
Jaakad si gaar ah loo qaabeeyey oo madaw polyester-ka madaw ah ama koodhka sare ee fluorocarbon ayaa lagu dul marsadaa curiyaha la daweeyey. Xakamaynta saxda ah ee dhumucda dahaarka iyo isticmaalka walaxaha dahaarka waxay xaqiijinayaan dhammays joogto ah, dhalaal hooseeya (tusaale, 10-30 GU). Gariiraddu waxa ay martaa wareeg labaad oo daaweyn ah oo la kantaroolo si ay iskaga gudubto polymers-ka oo ay u xidho midabka madow ee qoto dheer iyo midabka matte.

Kormeerka ugu dambeeya, Goynta, iyo Xirmooyinka Ilaalinta
qaboojinta ka dib, xaashida waxa lagu maraa kormeer adag oo lagu eegayo lebbiska midabka, heerka dhalaalka, xabagta dahaarka (tijaabada la gooyay), iyo cilladaha dusha sare. Go'yaal u qalma ayaa loo gooyay cabbir cayiman, iyo filim ilaalin ah polyetylen (PE) ayaa lagu dabaqayaa oogada si looga hortago xagashada inta lagu jiro maaraynta iyo gaadiidka.
