Izinto Zokumboza Ngempushana Namuhla Nakusasa

Namuhla, abakhiqizi be i-powder coating izinto ezisetshenziswayo ziye zaxazulula izinkinga zesikhathi esidlule, futhi ucwaningo oluqhubekayo nobuchwepheshe buqhubeka nokudiliza izithiyo ezimbalwa ezisele zokumboza impushana.

Izinto Zokumboza Impushana

Impumelelo yezinto ezibonakalayo ebaluleke kakhulu kube ukuthuthukiswa kwezinhlelo ze-resin eziklanyelwe ukuhlangabezana nezidingo ezihlukahlukene neziqondile zemboni yokuqeda insimbi. Ama-epoxy resins ayesetshenziswa cishe kuphela phakathi neminyaka yokuqala yokumbozwa kwempushana ye-thermosetting futhi asasetshenziswa kabanzi namuhla. Ukusetshenziswa kwama-polyester resins kukhula ngokushesha emakethe yaseNyakatho Melika futhi ama-acrylics ayisici esikhulu kubasebenzisi abaningi bokugcina, njengezimboni zikagesi nezezimoto.

Ama-Powders atholakala ngokukwazi ukumelana nokugqwala, ukushisa, umthelela, nokuhuzuka. Color ukukhetha akunamkhawulo cishe ngesicwebezelisi esiphezulu nesiphansi, futhi ukuqeda okucacile kuyatholakala. Izinketho zokuma zisuka ezindaweni ezibushelelezi ziye kokushwabene noma okumatte. Ukushuba kwefilimu nakho kungahlukahluka ukuze kuhambisane nezimfuneko zezinhlelo ezithile zokusebenza.

Ukuthuthukiswa kwezinhlelo ze-resin kubangele ingxube ye-epoxy-polyester, ehlinzeka ngongqimba oluncane, oluphansi- ~ oluphulukisayo lwempushana. Ukuthuthuka kwe-polyester ne-acrylic resins kuthuthukise ukuqina kwangaphandle kwalezi zinhlelo. Intuthuko ethile kubuchwepheshe be-resin ihlanganisa:

• Izingubo zempushana ezinongqimba oluncane ezisuselwe kuma-epoxy-polyester hybrids zinikeza izinhlelo zokusebenza ebangeni elingu-1 ukuya ku-1.2 mils ngemibala enamandla okufihla okuhle. Lawa mafilimu azacile okwamanje afanele ukusetshenziswa kwangaphakathi kuphela. Amafilimu amancane kakhulu, angadinga ukugaya okukhethekile kwe-powder, angaba ngaphansi kuka-0.5 mils.
• Izindwangu zempushana ezinezinga lokushisa eliphansi. Izembatho zempushana ezinokusebenza kabusha okuphezulu zenzelwe ukwelapha emazingeni okushisa afinyelela ku-250°F (121°C). Izimpushana ezinjalo zokuphulukisa eziphansi zinika amandla isivinini somugqa ophezulu, ukwandisa umthamo wokukhiqiza ngaphandle kokudela ukuqina kwangaphandle. Baphinde andise isibalo substrates ukuthi kungaba powder camera, ezifana amanye amapulasitiki kanye nemikhiqizo yokhuni.
• I-Texture powder coatings. Lawa manamathela manje asukela ekuthunjweni okuhle okucwebezelayo okuphansi kanye nokumelana okuphezulu nemihuzuko nokuklwebheka, kuya ekuthungeni okumaholoholo okuwusizo ekufihleni indawo engalingani kwamanye ama-substrates. Lezi zingubo zokuthungwa zibe nokuthuthuka okukhulu uma kuqhathaniswa nezingxenye zazo zokubala ze-several iminyaka edlule.
• Izindwangu zempushana ezicwebezelayo eziphansi. Manje sekungenzeka ukunciphisa amanani egloss ngaphandle kokunciphisa ukuguquguquka, izici zomshini, noma ukubukeka kwezindwangu zempushana. Amanani acwebezelayo angehliswa abe ngu-1% noma ngaphansi kuma-epoxies amsulwa. Isicwebezelisi esiphansi kunazo zonke ezinhlelweni zepolyester ezimelana nesimo sezulu cishe singama-5%.
• Izindwangu ze-Metallic powder okwamanje atholakala ngemibala eminingi. Eziningi zalezi zinhlelo zensimbi zifanele ukusetshenziswa kwangaphandle. Ukuze kube nokuqina okuhle kwangaphandle, ijazi eliphezulu lempushana elicacile livame ukusetshenziswa phezu kwesisekelo sensimbi. Imizamo igxile ekuthuthukiseni okufanayo okuphelele kwemibala ejwayelekile ye-anodizing ukuze kuhlangatshezwane nezidingo zemakethe ye-aluminium extrusion. Enye intuthuko yakamuva ukushintshwa kwama-metal flakes ngezinto ezingezona ayoni njenge-mica.
• Izingubo zempushana ezicacile ziye zaba nentuthuko enkulu esikhathini esiyisikhombisa esidluleral iminyaka mayelana nokugeleza, ukucaca, nokumelana nesimo sezulu. Ngokusekelwe ku-polyester nama-acrylic resins, lezi zimpushana ezicacile zibeka izindinganiso zekhwalithi emasondweni ezimoto, izinto ezilungiswayo zamapayipi, ifenisha, nehadiwe.
• Izigqoko zempushana ezinesimo sezulu esiphezulu. Kuye kwenziwa intuthuko enkulu ekuthuthukiseni amasistimu e-polyester ne-acrylic resin anesimo sezulu esihle kakhulu sesikhathi eside ukuhlangabezana neziqinisekiso ezinwetshiwe ezinikezwa abakhiqizi. Okunye okusathuthukiswayo kukhona izimpushana ezisekelwe ku-fluorocarbon, ezizohambisana noma zeqe isimo sezulu sama-fluorocarbon awuketshezi, nezindleko ezisetshenzisiwe ezizuzisa impushana.

Ukumboza ngempushana sekubuye kwaba isiphetho esisebenzayo emikhiqizweni ekhiqiza amazinga okushisa abalulekile, njengezinto zokukhanyisa ezithengiswayo, futhi okokuqala eziqongweni ze-grill, lapho isebenza njengesisekelo sejazi eliphezulu eliwuketshezi.

Abakhiqizi bempushana bayaqhubeka nokwenza i-resin ephelele kanye nemiklamo ye-ejenti yokwelapha. Imizamo yamanje yocwaningo igxile ekuthuthukiseni nasekuthuthukiseni izimpushana ezinenani eliphansi, ezelaphayo ukuze zisize ukwandisa isicelo sokumboza ngempushana kuma-substrates amasha. Umsebenzi uyaqhubeka ekwenzeni izimpushana ezihlala isikhathi eside ezinesimo sezulu esiphezulu ukuze zisetshenziswe kakhulu ngaphandle, okubonisa ukumelana okuphezulu nokuchaki noma ukufiphala ekukhanyeni kwelanga.
