Yemvelo sombala anticorrosive - minium Ukuhola

phambili Red noma oxide phambili (PB ₃ O ₄₎ - into ezinzile amakhemikhali, okuyinto zingaxazululeki emanzini futhi sulfuric acid. Kuhle eyaziwa ngokuthi high sombala zemvelo orange noma umbala isitini-bomvu, ingxenye kwenziwa anti-ukugqwala futhi uyinki kabanzi umkhuba ukumaska.

incazelo

Minium phambili (GOST 19151-73) kuyinto crystalline esindayo powder kokuba ubukhulu kuyizinhlayiyana ka 2 kuya ku-10 microns, okuyinto etholakala ku inqubo ezishisayo namachibi litharge, powder phambili semifinished nomoya-mpilo. Ingqikithi has high density, kuyinto oxidizer eqinile. Impahla yokugcina futhi inquma kwenkululeko isicelo yayo njenge-ejenti anticorrosive lichaza ekwakheni phansi, putties, upende, putties m. N. Lapho ngokujoyina minium wasithukuthelela yensimbi phezu kwensimbi elicinene eliqinile oxide ifilimu esivikela ebusweni iphathwa metal izakhiwo kusuka ukugqwala. Khiqiza it kuphela izitshalo zamakhemikhali. Ingqikithi kuqhathaniswa esinobuthi, ngokuhambisana namazinga isiRashiya, ezihlobene lokuqala ekilasini ingozi, ngakho ukubekile waba ngesisekelo umbala wakhe "minium Lead" uvinjelwe ukuze isetshenziswe zokuhlala kanye nezakhiwo zomphakathi.

isicelo

Injongo eyinhloko sombala phambili - nikela anda anti-ukugqwala izakhiwo upende ukwakhiwa, ezisetshenziswa for metal izakhiwo kanye evele, kuhlanganise umonakalo kusuka ukugqwala noma isikali ezisalayo. Lezi izinto kabanzi shipbuilding ngoba priming ngidwebe evele Ingaphandle wadalula amanzi anosawoti bese ejenti ozungeze umhlaba wethu. Minium phambili akesabi abezindaba ezonakalisayo, has a adhesion okusezingeni eliphezulu kuyindlela ephumelela ukugqwala inhibitor. Ingasetshenziselwa ukwakha enamathela zokuzivikela futhi zokuhlobisa ngokhonkolo njalo nakakhulu futhi izakhiwo zikakhonkolo. Ngaphezu kwalokho, minium adingekayo yokukhiqiza phambili amabhethri, futhi enkulu ekwakhekeni crystal ingilazi kanye amamaki athile zokuzivikela amelana ngemisebe ingilazi optical. Ngo umkhakha chemical siwulimi reactant ekulungiseleleni acetate, carbonate, nezinye phambili compounds. Inhlama minium phambili iphikelela isisekelo fillers futhi plasters ezisetshenziswa emhlanganweni uwoyela, amanzi kanye umusi amapayipi. Kwenziwe ngokusebenzisa sombala wathi sokuvikelwa gamma-emisebeni ngokumelene, kanye ukwenziwa okufanayo futhi abanye thermite iziqhumane.

Sokuphuzisa "Minium phambili" upende

Ngaphambi kokufaka isicelo upende kufanele kube okuxubile kahle, futhi uma kudingeka, buhlanjululwe kuya wayefisa viscosity uketshezi: nemimoya kuphela noma amaminerali. Ingasetshenziselwa le nhloso futhi nenye toluene ne kuphela endaweni isilinganiso 1: 1. Surface ukuba umbala, ehlanzekile degrease. Uyinki siphelile, okuyinto lokushisa kufanele kube ngezansi 15 ^{° C,} kufanele zisetshenziswe izingqimba ezimbili nge ibhulashi, roller noma isifutho. Kumele yizinambuzane air lokushisa (5 kuya 35 degrees). Ukuze ome ungqimba ngamunye unikezwa okungenani amahora ama-2. Phakathi upende minium ashukumise kaningi ngangokunokwenzeka ukuze ugweme sokuxazulula izinhlayiya esindayo efana phansi ethangini.

Ukupakisha, isitoreji kanye zokuhamba ukwakheka kombala

Minium nomthofu phama ezitsheni steel, izigubhu lokhuni noma le plastic, ipulangwe, steel emaplastikini lacinile nobe ebhokisini-ezivuzayo izigubhu, iziqukathi ekhethekile ezithambile zalutho. Iziqukathi kufanele kube amanzi. Uthuthwa iyiphi indlela yokuthutha kuhambisana nemithetho isivikelo ingress umswakama ozungeze umhlaba wethu. Gcina sombala phambili phama ezomile emafektri ivaliwe ezingeni lokushisa -40 ^{° C} ... + 40 ^° C unyaka kuya ku-1 kusukela usuku ukwakhiwa. Njengoba sazi ukuthi ukuhola kuyinto minium anobuthi, ezokuthutha kanye isitoreji kufanele ulandele kudingekile zokuphepha.
