Anticorrosive zachilengedwe pigment - kutsogolera okusayidi

Kutsogolera oksidi, kapena oxyde yotsogoza (Pb ₃ O ₄ ) ndi mankhwala osungunuka pamadzi omwe salowerera m'madzi ndi sulfuric acid. Koposa zonse, amadziwika kuti ndi mtundu wobiriwira wa mtundu wa lalanje kapena wa njerwa, zomwe ndi mbali ya dothi losavuta komanso zojambula zomwe zimagwiritsidwa ntchito kwambiri pa kujambula.

Kufotokozera

Mtsogoleri (kutsogolera) (GOST 19151-73) ndi ufa wolemera kwambiri wa kriststine wokhala ndi tinthu ting'onoting'ono ta 2 mpaka 10 μm, omwe amapezeka panthawi yothandizira kutentha kwa mankhwala omwe amamaliza kupanga ndi kutulutsa ufa ndi mpweya wa mpweya. Thupi lili ndi mphamvu yochulukirapo, ndiyo yodalirika kwambiri. Zomwe zimapangidwanso zimapangitsanso kuti ntchitoyi ikhale yopangidwa ndi dothi, masitini, mapaipi, masitini, ndi zina zotero. Pamene surrey akuyimbidwa ndi chitsulo, filimu yowonjezereka imapangidwa pamwamba pazitsulo, zomwe zimatetezera kuti zitsulo zikhale zotsekemera. Zibweretseni izo kokha mu mankhwala a mankhwala. Thupili ndi poizoni ndipo, malinga ndi muyeso wa Russian, amadziwika kuti ndilasi yoyamba yowopsa, choncho utoto wotchedwa "Leader Suric" womwe unakhazikitsidwa pamalo ake ndi oletsedwa kuti ugwiritsidwe ntchito m'nyumba zogona .

Ntchito

Cholinga chachikulu cha kutsogolera mtundu wa pigment ndikuteteza kupopera kwa utoto wa mapepala ndi ma varnish omwe amagwiritsidwa ntchito popanga zitsulo ndi malo, kuphatikizapo zowonongeka ndi dzimbiri kapena zotsalira. Zipangizozi zimagwiritsidwa ntchito mwakhama kumanga nsomba kuti zikhale zojambula ndi zojambula za malo akunja omwe amadziwika ndi madzi a m'nyanja yamchere ndi mlengalenga. Kutsogolera kutsogolera sikuchita mantha ndi mauthenga achiwawa, ali ndi mphamvu zowonjezera, ndizomwe zimayambitsa kutupa. Ikhoza kugwiritsidwanso ntchito popanga chophimba chokongoletsera cha konkire yowonjezeredwa ndi zomangamanga. Kuwonjezera pamenepo, kutsogolera oksidi kumafunika kuti apangire mabatire, komanso kupanga kristalo ndi zina zotetezera, zowonongeka ndi magetsi. M'makampaniwa, amagwiritsidwa ntchito posintha mankhwala a acetate, carbonate ndi mankhwala ena otsogolera. Chotsitsimutsa chotsogoleredwa ndizitsulo ndizo maziko a zitsulo zopitilira ndi zokutira, zomwe zimagwiritsidwa ntchito pamsewu wa mafuta, mpweya ndi madzi. Zimagwiritsidwa ntchito pogwiritsa ntchito pigmentyi pofuna kutetezera mazira a gamma, komanso kupanga masewera ndi mabomba otentha .

Mmene mungagwiritsire ntchito utoto "Tengani Chitsulo Chotsatira"

Musanagwiritse ntchito, pepala iyenera kusakanikirana bwino, ndipo ngati n'koyenera, iwonetsedwe kwa minofu yofunikira yomwe imapezeka ndi solvents: zosungunulira kapena mchere. Mungagwiritse ntchito pazifukwazi zosakaniza za toluene ndi zosungunula mu chiŵerengero cha 1: 1. Malo opangidwa ndi utoto ayenera kutsukidwa ndi kuchepa. Okonzekera utoto, kutentha kumene kumayenera kukhala osachepera 15 ^o C, ayenera kugwiritsidwa ntchito mu zigawo ziwiri ndi mfuti ya brush, roller kapena spray. Pankhani iyi, m'pofunika kuganizira kutentha kwa mpweya (kuchokera madigiri 5 mpaka 35). Masentimita aliwonse amauma kwa maola awiri okha. Pogwiritsa ntchito pepala, mpiru umayenera kusakanikirana nthawi zambiri kuti usagwiritse ntchito mankhwala olemera omwe ali pansi pa chidebecho.

Kupaka, kusungirako ndi kutumiza mtundu wa pigment

Konzani oksidi yodzaza ndi mitsuko yachitsulo, mbiya zamatabwa kapena polyethylene, plywood, zitsulo kapena makatoni, zitsulo zosavuta. Phukusilo liyenera kukhala lopanda madzi. Kutengeka ndi njira iliyonse yobweretsera mogwirizana ndi malamulo otetezera ingress wa chinyezi chamlengalenga. Nkhokwe yoyamba imasungidwa mu mawonekedwe odzaza malo osungiramo zitsekedwa zouma pa kutentha kwa -40 ^о С ... +40 ^о С osapitirira chaka chimodzi kuchokera tsiku lopangidwa. Poganizira kuti kutsogolera kutsogolo ndi poizoni, panthawi yopititsa komanso kusungirako ndikofunikira kutsatira ndondomeko zoyenera zotetezera.
