Si loo rinjiyeeyo xaashida birta ah si wax ku ool ah, diyaarinta saxda ah ee dusha sare iyo agabka gaarka ah ayaa muhiim u ah birta aan dalool lahayn, oogada u adkaysanaysa daxalka. Hoos waxaa ku yaal hage dhammaystiran oo ku salaysan hab-dhaqannada warshadaha:

1. Diyaarinta Dusha sare (Tallaabada ugu halista badan)

• Dereasing: Ka saar saliidaha, wasakhda, ama haraaga adigoo isticmaalaya dareerayaasha sida acetone, isopropyl alkohol, ama nadiifiyeyaasha khaaska ah ee birta ah. Hubi in dusha sare uu si buuxda u engegay ka dib.

• Abrasion: Dusha sare ka dhig si aad u hagaajisid ku dheggan rinjiga:

  • Mashiin ahaan ku xoq 120-240 warqad ciid ah ama isticmaal ciid-qarxinta (gaar ahaan waxtar u leh aagagga waaweyn). Tani waxay abuurtaa "profile" rinjiga si uu u qabsado.

  • Dhammaystirka muraayadaha/dhammaystirka (tusaale, 8K/12K), naaxinta gardarada ah waa lama huraan

• Daawaynta miridhku: Haddii miridhku jiro (tusaale, alxanka ama xagashada), ka saar jajabyada dabacsan burushka siliga oo mari saliid lidka ku ah miridhku ama beddelayaasha fosfooraska ku salaysan si korka loo dejiyo.
• Hadhaaga Nadiifinta: Ku masax boodhka ama marada qoyan.

2. Farsamaynta

• Isticmaal qalab bir u gaar ah:

  • Qoryaha is-qurxinta: Kiimiko ahaan waxay ku xidhan yihiin birta aan lahayn (tusaale, epoxy ama qaababka zinc-hodanka ah).

  • Aasaasayaasha ka-hortagga daxalka: Bey'ada bannaanka/qalafsan, ka fiirso curiyayaasha leh sifooyin ilaaliya miridhku (tusaale, salida saliidda linseed-ku-salaysan ee caabbinta biyaha ee la xoojiyay).

• Codso jaakado khafiif ah, xitaa jaakado. Oggolow qalajinta buuxda sida ku cad tilmaamaha soo saaraha (sida caadiga ah 1-24 saacadood).

3. Codsiga Rinjiga

• Noocyada Rinjiga:

  • Rinjiyada buufinta (Aerosol): Ku habboon xitaa daboolka go'yaasha fidsan. Isticmaal akrilik, polyurethane, ama qaabaynta dhaldhalaalka ee ku calaamadsan birta. Gasacaduhu si xoog leh u rux ilaa 2+ daqiiqo kahor isticmaalka.

  • Burush/Roller: Isticmaal rinjiga birta ah ee ku dheggan (tusaale, alkyd ama epoxy). Iska ilaali jaakadaha qaro weyn si aad uga hortagto dhibco.

  • Ikhtiyaarada gaarka ah:

    • Rinjiga saliidda Linseed: Aad ugu fiican adkeysiga dibadda; waxay u baahan tahay jaakad hoose oo saliid ka hortag ah.

    • Dahaarka budada: Xirfadlayaasha foornada-la daaweeyay ee cimri dherer sare leh (ma aha DIY-saaxiibtinimo).

• Farsamada:

  • Ku qabo gasacadaha buufinta meel u jirta 20-30 cm.

  • Codso 2-3 jaakad khafiif ah, sug 5-10 daqiiqadood inta u dhaxaysa jaakadaha si aad uga fogaato inay hoos u dhacdo.

  • Ku ilaali isku-xidhnaan joogto ah (50%) daboolida labbiska.

4. Daawaynta & Shaabadeynta

U oggolow rinjiga inuu si buuxda u bogsiiyo (caadiyan 24-72 saacadood) ka hor inta aan la taaban.

Meelaha labbiska sareeyo, mari jaakad cad oo poliurethane ah si aad u xoojiso iska caabinta xoq/UV.

Daawaynta ka dib: Isla markiiba ka saar buufiska xad dhaafka ah ee dareeraha ah sida jinniyada macdanta.

5. Cilad-baadhista & Dayactirka

• Arrimaha Guud:

  • Diritaan/Naaro: Waxaa sababa nadiifin ku filan ama ka boodi agabka hore.

  • Kalluunka: Natiijada wasakhowga dusha sare; dib-u-nadiif iyo ciid meelaha ay saamaysay.

  • Midabka kulaylka: Haddii alxanku dhaco rinjiyeynta ka dib, isticmaal weelka kulaylka naxaasta/aluminiumka si loo yareeyo burburka; ku nadiifi summada leh koollada la jarjaray.

• Dayactirka: Dib u codso saliid ka hortagta miridhku ama rinjiga taabashada 5-10 sanoba mar meelaha bannaanka 3.

Beddelka Rinjiyeynta

Electroplating: Waxay kaydisaa chromium, zinc, ama nikkel si ay u adkaysato/iska caabbinta daxalka.

Ku buufinta kulaylka: Dahaarka HVOF/plasma ee caabbinta xidhashada xad dhaafka ah (adeegsiga warshadaha).

Qurxinta dhammaatay: Go'yaal bir ah oo aan lahayn midab hore (tusaale, muraayad dahab ah, la cadayday) waxay baabi'isaa baahida rinjiyeynta.

Qoraalada Badbaadada

Ka shaqee meel hawo leh; u isticmaal qalabka neefsashada ee rinjiga buufinta.

Ku kaydi rinji ka hooseeya 45 ° C oo tuur maryaha si habboon (qalabka linseed-saliid-qoyan ayaa iskood isu shidi kara).

Talo-siinta Pro: Codsiyada muhiimka ah (tusaale, baabuurta ama qaab-dhismeedka), tijaabi habka diyaarinta/rinjigaaga gabal yar oo qashinka marka hore. Adhesion failure ee birta aan fiicnayn waxay had iyo jeer sabab u tahay diyaarin la'aanta dusha sare!
