Ungasikhetha njani iPowder efanelekileyo yeeMveliso zakho
Ungayikhetha njani iPowder eLungileyo yeeMveliso zakho Ukukhetha inkqubo ye-resin, ukuqina, kunye ne-pigment sisiqalo nje ekukhetheni iipropathi umntu anokuzifuna xa kugqitywa. Ukulawulwa kweglosi, ukuguda, izinga lokuqukuqela, izinga lokunyanga, ukunganyangeki kwe-ultra violet, ukumelana nemichiza, ukumelana nobushushu, ukuguquguquka, ukuncamathela, ukumelana nomhlwa, ukuqina kwangaphandle, ukukwazi ukuphinda kubuyiselwe kwaye kusetyenziswe kwakhona, ukusebenza kakuhle kokudluliselwa okokuqala, kunye nokunye yezinto ekufuneka ziqwalaselwe xa kukho naziphi na izinto ezintshaFunda ngokugqithisileyo …
I-TGIC yokutshintshwa kweekhemistri kwi-powder coating-Hydroxyalkylamide (HAA)
IHydroxyalkylamide(HAA) TGIC Replacement chemistries Njengoko ikamva le-TGIC lingaqinisekanga, abavelisi bafuna enye indawo elinganayo. I-HAA yonyango efana ne-Primid XL-552, iphuhliswe kwaye iphawulwe yi-Rohm kunye ne-Haas, iye yaziswa. Eyona nto ibuyisela umva kwezo ziqinisi kukuba, njengoko indlela yokunyanga ikukusabela kokujiya, iifilimu ezakha zafikelela kubukhulu obungaphezulu kwe-2 ukuya kwi-2.5 mil (i-50 ukuya kwi-63 microns) zinokubonisa ukukhupha umoya, ukuphina, kunye nokuhamba kakubi kunye nokulinganisa. Oku kuyinyaniso ngakumbi xa eziFunda ngokugqithisileyo …
Ezinye izinto ezibalulekileyo zokuthotywa kwe-polyester yokwambathisa
Ukuthotywa kwePolyester kuchatshazelwa yimitha yelanga, i-photocatalytic admixtures, amanzi kunye nokufuma, iikhemikhali, ioksijini, i-ozone, ubushushu, i-abrasion, uxinzelelo lwangaphakathi nangaphandle, kunye ne-pigment fading. Kuzo zonke ezi zinto zilandelayo, zonke zikhoyo kwimozulu yangaphandle, zikho eyona nto ibalulekileyo ukuthotywa komgangatho: ukufuma, amaqondo obushushu, i-oxidation, imitha ye-UV. Ubumanzi I-Hydrolysis yenzeke xa iplastiki ibonakaliswe kumanzi okanye ukufuma.Le mpendulo yeekhemikhali inokuba yinto ephambili ekuthotyweni kweepolymers ze-condensation ezifana ne-polyesters, apho iqela le-esterFunda ngokugqithisileyo …
Iimfuno zokugquma umgubo phezu kwediphu eshushu yokugalela
Le ngcaciso ilandelayo iyacetyiswa: Sebenzisa i-zinc phosphate pretreatment ukuba kukho ukuncamatheliswa okuphezulu. Umphezulu kufuneka ucoceke ngokugqibeleleyo. I-zinc phosphate ayinayo into yokucoca kwaye ayiyi kususa ioli okanye umhlaba. Sebenzisa i-iron phosphate ukuba umsebenzi osemgangathweni uyafuneka. I-iron phosphate inesenzo esincinci sokucoca kwaye iya kususa ungcoliseko oluncinci lomhlaba. Eyona isetyenziswayo kwiimveliso zangaphambili. Umsebenzi wokufudumala ngaphambi kokusetyenziswa komgubo. Sebenzisa i-'degassing' yomgangatho wepolyester yokwambathisa kuphela. Khangela unyango oluchanekileyo nge-solventFunda ngokugqithisileyo …
