Description
Išradimas skirtas statybinių medžiagų gamybai, konkrečiai lengvojo betono gamybai.The invention relates to the production of building materials, in particular to the production of lightweight concrete.
Yra žinomas termoizoliacinių dirbinių gavimo būdas, pasižymintis tuo, kad išpūstas perlitinis smėlis sumaišomas su lignosulfatų rišamuoju skiediniu, formuojami gaminiai ir jie termiškai apdorojami. Yra naudojami kalcio ir natrio lignosulfatai, o terminis apdorojimas atliekamas 280-300°C temperatūroje, trukmę skaičiuojant priėmus 1,0-1,5 min. 1 mm gaminio storio (žr. TSRS aut.There is a known method of obtaining thermal insulating articles, characterized in that the expanded pearlite sand is mixed with lignosulphate binder, molded and heat treated. Calcium and sodium lignosulphates are used and the heat treatment is carried out at 280-300 [deg.] C. for a duration of 1.0-1.5 min. 1 mm of product thickness (see USSR aut.
liud. Nr. 1600298, TIK5 C04B 38/08).witness No. 1600298, ONLY 5 C04B 38/08).
Taip pat yra žinomas klojimų nuėmimo būdas, kuris gali išsaugoti gaminio iš betono formą iki visiško sukietėjimo. Klojinių nuėmimas yra atliekamas apverčiama forma, ant kurios yra dedamas skydinis padėklas. Forma su skydu yra pasukama 180°, padedama ant grindų ir nuimama nuo gaminio. Apverčiamas formas galima panaudoti bet kokioje įmonėje (žr. Chitrov V.G. “Technologija opalubočnich izdielij” Visšaja škola, Maskva, 1967, psl. 333).There is also a known method of stripping, which can preserve the shape of the concrete product until it hardens completely. Formwork removal is done in an inverted form on which a panel pallet is placed. The panel with the panel is rotated 180 °, placed on the floor and removed from the product. Inverted forms can be used in any company (see Chitrov, V.G., "Technology opalubočnich izdielij" Vyshaya schola, Moscow, 1967, p. 333).
Artimiausias pagal techninę esmę yra lengvų betoninių dirbinių gamybos būdas, pasižymintis tuo, kad vežimėlių padėklai nuvalomi, tepami, paruošiamas betono mišinys, kuris išliejamas ir suplūkiamas, apdorojamas karštais garais, gaminys išimamas ir sudedamas ant specialių priemonių (žr. ten pat, psl. 335).The closest to the technical essence is the method of manufacturing lightweight concrete products, characterized in that the trolley trays are cleaned, lubricated, a concrete mixture is poured and blown, hot steam treated, the product is removed and placed on special tools (see also page 335). ).
Tačiau pagal nurodytą prototipą naudojamas mechaninis metalinių formų dugnų valymo būdas po gaminių iš lengvo betono apdorojimo karštais garais reikalauja didelių darbo ir energijos sąnaudų, negarantuoja reikiamos valymo kokybės, pažeidžia metalinių dugnų paviršių.However, the mechanical protuberance of metal molds used in the above prototype, after hot steam treatment of lightweight concrete products, requires high labor and energy costs, does not guarantee the required cleaning quality and damages the metal bottom surface.
Siūlomo išradimo tikslas yra formų valymo palengvinimas lengvo betono gamybos procese.The object of the present invention is to facilitate the cleaning of molds in the production of lightweight concrete.
Norint palengvinti metalinių formų valymą, žinomame lengvo betono gamybos būde, pasižyminčiame tuo, kad paruošiamas akyto betono mišinys, tepama forma, formuojamas masyvas, kuris supjaustomas, gaminiai termiškai apdorojami garais. Siūlomo būdo naujumas yra tas, kad kai masyvas metalinėje formoje įgauna plastinį atsparumą 30-35 KPa, yra nuimami formos bortai nuo dugno ir hidraulinio griebtuvo, pritvirtinto prie keliamojo mechanizmo, pagalba masyvas su formos bortais yra pernešamas ant paguldyto šalia metalinio padėklo, sutepto tos pačios sudėties, kaip ir metalinė forma, tepalu. Jo konstrukcija yra analogiška metalinės formos dugno konstrukcijai. Po to masyvas yra termiškai apdorojamas garais.In order to facilitate the cleaning of metal forms, the known lightweight concrete production method comprises preparing a porous concrete mixture in a lubricated form, forming an array that is cut, and heat treating the products with steam. The novelty of the proposed method is that when the array in the metal form gains a plastic resistance of 30-35 KPa, the molded sides are removed from the bottom and a hydraulic gripper attached to the lifting mechanism helps to transfer the array with the shaped sides to the composition, like the metal form, with grease. Its construction is analogous to that of a metal-shaped bottom. The array is then heat treated with steam.
Išradimo pramoninio panaudojimo galimybė yra pateikta pavyzdyje.The industrial application of the invention is exemplified.
Pagal gamybos būdą, taikomą lengvajam betonui, kurio tūrio masė 500 kg/m3, formavimo mišinio sudėtis yra nustatoma tokiais rodikliais: masės aktyvumas pagal kalkes sudaro 11%, masės aktyvumas pagal cementą sudaroAccording to the production method for lightweight concrete with a volume of 500 kg / m 3 , the composition of the formation mixture is determined by the following: mass activity by weight of lime is 11%, mass activity by weight of cement is
9%, vandens-kietų medžiagų santykis 0,45-0,5, aliuminio pudra sudaro 0,1% nuo sausų medžiagų, užpildas - kvarcinis smėlis.9%, water-solids ratio 0.45-0.5, aluminum powder 0.1% of dry matter, filler - quartz sand.
Paruoštu akytbetonio mišiniu yra užpildoma metalinė forma, susidedanti iš dugno ir pritaisytų prie jo bortų. Prieš užpildant, metalinė forma sutepama tepalu iš solidolio ir panaudoto mašininio tepalo, esant komponentų masės santykiui 1:2-1:3 (galima naudoti ir kitus tepalus, kurie neleidžia masyvui prilipti prie formos - dizelinį kurą, petrolatumą, emulsolą). Masyvo išpūtimas atliekamas smūgių poveikiu specialioje aikštelėje 5-10 min., po to metalinė forma su masyvu yra nuimama nuo smūgių aikštelės ir paliekama brendimui. Masyvas 30-35 KPa plastinį atsparumą įgauna per 1-1,5 valandos, esant temperatūrai 18-20°C. Masyvui įgavus nurodytą plastinį atsparumą, bortai yra nuimami nuo metalinio dugno ir masyvas su bortais yra perkeliamas ant kito sutepto metalinio padėklo. Supjausčius masyvą į reikiamo dydžio gaminius, metalinis padėklas su masyvu yra paduodamas į autoklavą ir 14,5 valandos apdorojamas garais, esant garo slėgiui 0,8-1,0 MPa. Nuėmus gaminius ir nuvalius metalinius padėklus nuo masės likučių, metaliniai padėklai yra grąžinami į formavimo skyrių pakartotinam panaudojimui.The prepared aerated concrete mixture is filled with a metal form consisting of a bottom and attached to its sides. Before filling, the metal form is lubricated with a solidol to machine lubricant grease at a component weight ratio of 1: 2-1: 3 (other lubricants can also be used which prevent the solid from sticking to the form - diesel fuel, petrolatum, emulsion). The blasting of the array is effected by impact on a special site for 5-10 minutes, after which the metal mold with the array is removed from the impact site and left to mature. The array acquires 30-35 KPa plastic resistance within 1-1.5 hours at 18-20 ° C. Once the array has the specified plastic resistance, the sides are removed from the metal bottom and the array with sides is moved to another lubricated metal pallet. After cutting the array into articles of the required size, the metal tray with the array is autoclaved and steam-treated for 14.5 hours at a vapor pressure of 0.8-1.0 MPa. Once the articles have been removed and the metal trays have been cleaned of residues, the metal trays are returned to the forming compartment for reuse.
Tokiu būdu, perkėlus masyvą, po to kai jis įgauna plastinį atsparumą 3035 KPa ant metalinio padėklo, metalinės formos dugno valymas palengvėja dėl to, kad likusi ant dugno masė yra termiškai neapdorojama garais. Lengvo betono masyvas, pasiekęs plastinį atsparumą 30-35 KPa, perkeltas ant kito sutepto metalinio padėklo, neabsorbuoja tepalo, todėl termiškai apdorojant garais akyto betono masė neprilimpa prie metalinio padėklo, o tai žymiai palengvina jo paviršiaus valymą.In this way, after transferring the array, once it has gained a plastic resistance of 3035 KPa on a metal substrate, the cleaning of the metal-shaped bottom is facilitated by the fact that the remaining mass on the bottom is not heat-treated. The lightweight concrete block, which reaches a plastic resistance of 30-35 KPa when transferred to another lubricated metal substrate, does not absorb grease, so that the heat-treated porous concrete does not adhere to the metal substrate, which greatly facilitates its surface cleaning.
