imixube Phosphating ke iziseko bicomponent, ezenziwe phosphoric acid kunye diluent. Ukusebenzisa umxube ezifana ukuba zonke iintlobo yesinyithi. Oku kuphucula ibambelele.

Zokwambathisa primer isekhona alkyd okanye epoxy. Kujongwe ukuba ukukhusela komhlaba ukusuka ukufuma neoksijini. nokubunjwa kwayo - ebomvu oxide intsimbi, zinc oxide, kwakunye fillers. Kusetyenziswe ethile enjalo qho ukwenzela iintsimbi ayoni.

Metal passivation primer

Oku uyakwazi ukwehlisa iimpawu electrochemical. Azikhuli nokumelana. Ethetha ziyibuyisela ngumxube, ngoko yenza kwindawo entsha uhlobo ebambekayo wayesebenzisa-uhlobo lomhlaba, okuhlanganisa iimpawu ngezakhiwo ezimbini. Inhibitor efakwe nokubunjwa kwayo, kuba amanzi okanye oli-emanzini.

abanyatheli primer

Iyilelwe ukuba ukusebenza kunye nomphezulu ngekopi. Ukuba ufuna primer otyhidiweyo, ngoko ungakhetha kukhankanywe apha ngentla, nto yenziwa wemagniziyam ingxubevange xa idibene nezinki nomgubo bakhokele. Phezu emva kokuba isicelo wadala ezingabonakaliyo umboniso, ezinako, kwanaxa sibange ukukhusela isiseko metal. Oku kuye kwafezwa enkosi amasuntswana nezinki, ezo ziyinxalenye primer. Lidla kuyimfuneko ukunyanga umphezulu, leyo sele ngeenkqubo ukurusa. Kukho kwakhona kwenziwa, isicelo sabo wenziwe emva kumphezulu moya. Emva kokuba base uba ukhuselwe ibingenakunyakama.

Ingakumbi ukhetho kunye nesicelo

Ukuba ufuna primer otyhidiweyo, kufuneka kuqala ukuziqhelanisa wena kunye neenqobo apho ukhetho yenziwa.

Ekuqaleni, umphezulu kufuneka izishiye zokwaleka endala, acoca ngayo ukungcola nothuli kwakunye ezihambelana. Phakathi kwezinye izinto, oko kuyimfuneko ukuze enze bamafutha, kwaye ukususa umhlwa.

Metal primer ngu irusi kufuneka kuthwala izixhobo ezifanelekileyo, kusenokuba ibhrashi, spray umoya okanye edlala. Ukuba uya kusebenzisa yesibini khetho, ngoko ke umsebenzi igqitywe ngexesha elifutshane, kodwa esi sixhobo alusoloko abakhoyo yokugcina i wizard, kwaye lincothule ukuze sigubungele iinkalo ezincinane akukho ndlela. Xa kuthengwa izixhobo kubalulekile ukuba siqwalasele ukusetyenziswa, nge-avareji, eli nani isusela ukusuka grams 120 ukuya 140 square metre nganye. Oku kuyinyaniso nangubo zangaphantsi ngambini. Linani ngokwemilinganiselo yakowayo.

Phezu ngokwaneleyo ngokufuthi ukutyabeka elifumileyo-ubungqina uyasetyenziswa, ingakumbi kumayelana kwenziwa ukuba sisinyithi ziya kuboniswa yiqabaka kunye ikhephu. Yintoni primer okanye kusetyenziswa, kuyafuneka ukuba sigcine nemiqathango ukufuma kunye obushushu. Malunga noluhlu lokugqibela, oko zingaqala degrees -10 ukuya +25.

Features primer alkyd ukuba metal

metal yokupeyinta-lulungele Alkyd zingasetyenziswa njenge ukutyabeka elizimeleyo. Plus, zithako kukuba akukho mfuneko ukusebenzisa ipeyinti okanye lwawo phezu kwayo. iinzuzo eyongezelelweyo inokuchongwa ngokubonelela iimpawu anti-umhlwa kakhulu ngokunjalo into yokuba isicelo kumphezulu leyo boniswa inkqubo Ukurusa. Ngenxa yoko, oku kubonisa ukuba primer alkyd uba lokuguqulela. Lo mxube wakwazi ukunika ukhuselo isimo zemozulu ezahlukeneyo ngokuphathelele kwimitha yelanga, kwakunye notshintsho obushushu.

Zithako unalo igunya eliphezulu esitheleyo. Ngenxa aluminium khona impahla lokufaka ochazwe inika izithako ezongezelelekileyo zibandakanya alkyd ukhuselo banxibe.

It uneempawu Obusemagqabini ubunjani iyakwazi ukukhusela intsimbi kwimpembelelo yangaphandle. Super inxenye nizuze kunye lomqulu, umboleki kufuneka ahlawule 1170 engange. Ahlanganise phezu umxube, wena siyayikhusela nokulondoloza ubomi nkonzo. Ukuba ufuna yokuzunguleza kumphezulu indawo encinci, unako ukuthenga umxube uphawu-yokuqala abakhankanywe mali ka-1 kg, kulo mzekelo, kuya kufuneka ukuba uhlawule kwi iimathiriyeli kwivenkile zokwakha 120 engange. izinto brand Dufa kubiza engange 1600 ngelitha 2,5 nganye.

isiphelo

imixube ezichazwe ngokufanayo kwiimeko injongo yokusebenza. Umzekelo, ukuba primer metal iimoto uneempawu ezifanelekileyo. Nangona kunjalo, kukho imixube jikelele, ukuba ezifanelekileyo iindawo standard kunye neendawo ingxaki. Phakathi wokuqala kunokuba ndimlahlele ezihloniphekileyo, kwaphunyezwa, kunye nezinye iimveliso ukuba abe uburhabaxa eliphantsi komhlaba ephucula umgangatho ngcina, elungileyo kakhulu umsebenzi priming. Phakathi substrates eziyingxaki - ubhedu, i-aluminiyamu, zesinyithi kwalenza, kunye nazo naziphi na ezinye izinto ezinokuthi ukunika indlela kwemichiza phezu komhlaba kunye nokunciphisa adhesion.

Ukuba uya emazifunwe primer GF 021 metal, kufuneka bawuqhele iingcebiso lomenzi. Ngenxa yoko, ibhanka kuboniswa ixesha apho ukwakhiwa uyakwazi ukuqhuba le metal. iimpawu Anti-umhlwa ye ubume nayo ibalulekile. Zonke ezi mpawu phambi ukuthenga izinto eziyimfuneko ukuze sinikele ingqalelo ekhethekileyo. Kuya kuxhomekeka phakade ukutyabeka zikhusela intsimbi ngokwayo kunye nexesha lomsebenzi. Musa sinayo umxube primer kubhetele ukuthenga impahla yomvelisi, leyo ondiqinisileyo ngokwayo kwi lemarike izinto ezifanelekileyo.
