Abstract
Description
Izgudrojuma aprakstsDescription of the Invention
Paredzamais izgudrojums attiecas uz masas sastāvu stikia-kristāliskas emaljas pārklājumam uz leģēta hromniķela tērauda, kas raksturojas ar paaugstinātu termisko izplešanos.The present invention relates to a bulk composition for a vitreous crystalline enamel coating on an alloyed chromium nickel steel characterized by increased thermal expansion.
Šinī gadījumā pie masas sastāva netiek pieskaitītas komponentes, kas nepieciešamas emaljas šlikera iestādīšanai un stabilizācijai (māls, bentonīts, nātrija nitrīts, borakss), bet gan, ieskaitot emaljas friti, speciālas nozīmes piedevas (dažādi ugunturīgi oksīdi, šamots, fosfāti, pigmenti u.c.).In this case, the components necessary for the setting and stabilization of the enamel slipper (clay, bentonite, sodium nitrite, borax) are not included in the composition, but special additives (various refractory oxides, chamotte, phosphates, pigments, etc.) including the enamel frit.
Ir zināma masa stikia-kristāliskas emaljas pārklājumam, kura nodrošina emaljas slāņa nepieciešamo termisko izplēšanos pateicoties tam, ka termoapstrādes laikā pārklājumā izdalās kristāliskās fāzes - kristobalīts un tridimīts. Bet šo kristālisko fāžu izdalīšanās tiek panākta speciālas termoapstrādes laikā: izturēšana 900 °C temperatūra 2 st. [ 1],There is a known mass of vitreous-crystalline enamel coating, which provides the necessary thermal expansion of the enamel layer due to the crystalline phases crystalline and tridymite being released during the heat treatment. But the release of these crystalline phases is achieved by a special heat treatment: curing at 900 ° C for 2 hours. [1],
Ir izstrādāts emaljas masas sastāvs ar saīsinātu kristalizācijas laiku, kura rezultātā uzkausēšanas laikā pārklājumā izkristalizējas kristobalīts un tridimīts, tādējādi nodrošinot nepieciešamo emaljas pārklājuma termisko izplešanos. Bet šo mērķu sasniegšanai masas sastāvā jāievada liels daudzums - 40 līdz 100 masas daļas pigments (K 6038 - hroma-dzelzs oksīdu maisījums) [2] (prototips).An enamel mass composition with reduced crystallization time has been developed, which results in crystallization of cristobalite and tridymite in the coating during melting, thus providing the necessary thermal expansion of the enamel coating. But to achieve these goals, a large amount of 40 to 100 parts by weight of pigment (K 6038 - chromium-iron oxide mixture) [2] (prototype) must be added.
Pigmenta K 6038 apzīmējums: Cr-Fe tiefshwarz (deep black) Reimbold-strick (CHEMISCH-KERAMISCHE WERKE).Designation of pigment K 6038: Cr-Fe tiefshwarz (deep black) Reimbold-strick (CHEMISCH-KERAMISCHE WERKE).
Izgudrojuma mērķis ir izstrādāt emaljas masas sastāvu ar samazinātu nepieciešamā pigmenta daudzumu, vienlaicīgi saglabājot saīsinātu kristalizācijas laiku. Mērķis tiek sasniegts, izmantojot augstu S1O2 saturošu emaljas friti un masas sastāvā papildus pigmentam ievadot kristalizātoru (kristalizācijas veicinātāju) 30 līdz 70 masas daļas uz 100 masas daļām fiites. Kristalizātors ir: 100 masas daļas maltas smilts un 3 masas daļas sodas (bezūdens) maisījums, izkarsēts 1-2 st. 1000-1200 °C temperatūra un papildus sasmalcināts.The object of the present invention is to provide an enamel mass composition with reduced amount of pigment required while maintaining a short crystallization time. The objective is achieved by using a high S1O2-containing enamel frit and adding 30 to 70 parts by weight per 100 parts by weight of the crystallizer (crystallization enhancer) in addition to the pigment. The crystallizer is a mixture of 100 parts by weight of ground sand and 3 parts by weight of soda (anhydrous), heated for 1-2 hours. 1000-1200 ° C and additionally crushed.
Pieteiktais masas sastāvs nodrošina paātrinātu emaljas pārklājuma kristalizāciju un kristobalīta un tridimīta izdalīšanos tajā (sk. l.tabulū). Salīdzinājumam par pamatu (prototipu) ņemts masas sastāvs ar 40-100 masas daļām pigmenta piedevu [2].The applied mass composition provides accelerated crystallization of the enamel coating and the release of cristobalite and tridymite (see Table 1). For comparison, the basis (prototype) is the mass composition with 40-100 parts by weight of pigment additive [2].
1.tabulaTable 1
Kā redzams no 1.tabulas, piedāvātais masas sastāvs ar samazinātu nepieciešamā pigmenta daudzumu nodrošina analoģiskus, salīdzinot ar prototipu, kristalizācijas noteikumus un kristālisko fāžu izdalīšanos emaljas pārklājumā.As can be seen from Table 1, the proposed mass composition with the reduced amount of pigment required provides analogy with the prototype, crystallization rules and crystalline phase separation in the enamel coating.
