Description
Predmet izuma je postopek obdelave keramičnih delov, ki se uporabljajo v industriji umetnih sintetičnih vlaken, v namen recikliranja oz. bolj natančno postopek kontrolirane mehanske obdelave površine z namenom obdelave keramičnega dela do takšne stopnje, da dosežemo, da se lahko keramični del spet z istim namenom oz. istimi ali podobnimi karakteristikami ponovno uporabi v proizvodnem procesu umetnih sintetičnih vlaken kot jih ima nov keramični del.The object of the invention is a method of processing ceramic parts used in the synthetic fiber industry for the purpose of recycling or recycling. more precisely, the process of controlled mechanical surface treatment with a view to treating the ceramic part to such a degree that the ceramic part can be reclaimed for the same purpose or purpose. reuse the same or similar characteristics in the manufacturing process of artificial synthetic fibers as the new ceramic part.
Tehnični problem, ki ga predložen postopek po izumu uspešno rešuje je postopek recikliranja keramičnih delov, predvsem v industriji umetnih is sintetičnih vlaken, kjer so keramični deli prisotni v strojih in napravah za obdelavo vlaken.A technical problem that is successfully solved by the present process according to the invention is the process of recycling ceramic parts, in particular in the artificial and synthetic fibers industry, where ceramic parts are present in fiber processing machines and devices.
Predmetni izum omogoča nadzorovano mehansko obdelavo površine keramike z odstranjevanjem poškodovane/spremenjene površine z namenom doseči znano končno površino.The present invention provides controlled mechanical treatment of the surface of the ceramic by removing the damaged / altered surface in order to achieve a known end surface.
Keramični deli, ki se uporabljajo v industriji umetnih sintetičnih vlaken so ponavadi narejeni iz visoko kakovostne oksidne keramike, katere delež AI2O3 je okoli 99,6%. Za keramične materiale je značilna visoka mehanska trdnost, obstojnost pri visokih temperaturah (temp. tališča >2000°C), nizek koeficient toplotnega raztezanja ter korozijska obstojnosti. Keramični deli, ki so vgrajeni v proizvodni proces so izpostavljen ekstremnim pogojem obratovanja, kot so visoka hitrost teka umetnega vlakna (filamenta)do 5200 m/min, temperaturam od 30 doThe ceramic parts used in the synthetic man-made fiber industry are usually made of high quality oxide ceramics with an AI 2 O 3 content of about 99.6%. Ceramic materials are characterized by high mechanical strength, high temperature resistance (melting point> 2000 ° C), low coefficient of thermal expansion and corrosion resistance. Ceramic parts incorporated in the manufacturing process are exposed to extreme operating conditions, such as high filament running speeds up to 5200 m / min, temperatures from 30 to
80°C , količini matirnega sredstva (od 0% do 1,6% TiO2) ter vplivu oblike filamenta (trilobal, okrogla). Vsi prej opisani ekstremni pogoji povzročajo konstantne površinske spremembe na keramičnih delih.80 ° C, the amount of matting agent (0% to 1.6% TiO2) and the effect of filament shape (trilobal, round). All the extreme conditions described above cause constant surface changes on ceramic parts.
Keramika kot material je široko uporabljan v industriji umetnih sintetičnih vlaken pri postopkih predenja, teksturiranja, prekrivanja in v io nadaljevalnih nižjih stopnjah predelave/obdelave vlaken. Večinoma se nahaja v strojih kot deli pri oljilcih, repkih, usmerjevalnih vodilih, diskih za teksturirtanje vlaken, vodilnih diskih, delovnih diskih, rezalnih diskih, brizgalnih ploščah, usmerjevalcih vodil, keramičnih obročkih, valjastih rezilih, birotorjih ipd.Ceramics as a material are widely used in the synthetic man-made fiber industry for spinning, texturing, overlaying and in io continuing lower stages of fiber processing / processing. It is mainly found in machines as parts for oilers, tails, guide rails, fiber texturing disks, guide disks, work discs, cutting discs, spray discs, guide rails, ceramic rings, cylindrical blades, bureaucrators, etc.
is Kemijska korozija, trenje, površinska obraba in elektrostatične interakcije v proizvodnem procesu zahtevajo keramični material visoke površinske kakovosti. Večinoma so takšne keramike poznane kot tehnične keramike, kot je oksidna AI2O3 čistosti več kot 90% s kombinacijo primesi različnih aditivov, ki izboljšajo fizikalne karakteristike materiala. Glede na zahteve procesa izdelave vlaken po visoko zmogljivih mehanskih lastnostih je tudi proces izdelave keramike sestavljen iz dragih tehnoloških operacij, kot so visoke temperature sintranja do 1800°C, dolgih proizvodnih ciklov do 200 minut ali več kar pomeni veliko porabo energije.is Chemical corrosion, friction, surface wear and electrostatic interactions in the manufacturing process require high surface quality ceramic material. For the most part, such ceramics are known as technical ceramics, such as AI2O3 oxide with a purity of more than 90% with a combination of admixtures of various additives that enhance the physical characteristics of the material. Depending on the requirements of the fiber manufacturing process for its high mechanical properties, the ceramic manufacturing process also consists of expensive technological operations such as high sintering temperatures up to 1800 ° C, long production cycles of up to 200 minutes or more, which means high energy consumption.
Zato keramični deli v proizvodnji vlaken predstavljajo velik strošek, še posebej v primerih proizvodnje kritičnih vlaken. Poleg visokih stroškov vzdrževanja na strani proizvajalcev vlaken je na strani proizvajalcev novih keramičnih delov prisoten tudi velik vpliv na okolje v obliki porabe energije in strupenih izpušnih plinov med procesom sintranja.Therefore, ceramic parts in fiber production are a major expense, especially in the case of critical fiber production. In addition to the high maintenance costs of the fiber manufacturers, the manufacturers of new ceramic parts also have a major environmental impact in the form of energy and toxic exhaust emissions during the sintering process.
Dandanes so proizvajalci vlaken usmerjeni v optimizacije izplenov proizvodnega procesa in izboljšav v smislu kvalitete vlaken. Samo konstantni procesni pogoji in kvaliteten polimer lahko vodijo v smeri kvalitetnega vlakna in učinkovite nadaljnje predelave / obdelave vlaken.Today, fiber manufacturers are focused on optimizing outputs of the manufacturing process and improvements in terms of fiber quality. Only constant process conditions and high quality polymer can lead to quality fiber and efficient further processing / processing of fibers.
Eni izmed najbolj kritičnih delov proizvodne opreme v procesu izdelave vlaken so v okviru izuma keramični deli. Spremenjena in/ali poškodovana površina keramičnih delov zaradi samega proizvodnega procesa proizvodnje vlaken vodi k nehomogeni kvaliteti vlaken in je v veliki meri izražena v obliki različnih napetosti v vlaknu in posledično visoki is temperaturi.One of the most critical pieces of manufacturing equipment in the fiber manufacturing process is ceramic parts. The altered and / or damaged surface of the ceramic parts, due to the fiber production process itself, leads to the non-homogeneous quality of the fibers and is largely expressed in the form of different stresses in the fiber and consequently high and temperature.
Postopek po izumu omogoča, da se spremenjeni in/ali poškodovani in/ali izrabljeni keramični deli različnih dimenzij in oblik, ki predstavljajo odpadni stranski produkt procesov pridelave in predelave umetnih sintetičnih vlaken in podobnih procesov lahko obnovijo z izpostavitvijo posebnemu procesu obdelave površine z abrazivnimi sredstvi, ki dosega končno znano kvaliteto strukture površine.The process according to the invention allows the modified and / or damaged and / or worn ceramic parts of different dimensions and shapes, which represent a waste by-product of the processes of production and processing of synthetic synthetic fibers and similar processes, can be restored by exposure to a specific surface treatment process with abrasive agents, which achieves the final known quality of the surface structure.
S postopkom po izumu omogočimo, da se spremenjeni in/ali poškodovan in/izrabljeni keramični deli različnih dimenzij in oblik, ki so izločeni iz proizvodnega procesa zaradi povzročanja različnih napetosti vlakna, neenakomernega nanašanja preparacijskega olja, kapilarnih pretrgov, pojavu zank na bobini ter drugih fizikalnih in kemijskih sprememb na vlaknih, ki vodijo do nehomogenosti vlaken in nizkim proizvodnim izkoristkom v industriji umetnih sintetičnih vlaken in podobnih procesih, izpostavijo kontrolirani obdelavi površine z abrazivnimi delci ali pesku podobnimi delci (kot so diamantne kroglice oz. delci, kovinske kroglice oz. delci) in drugim abrazivnim materialom v obliki kroglic oz. delcev, ki se lahko uporabijo kot abrazivno sredstvo za površinsko obdelavo keramičnih delov, z namenom da dosežemo enake oz. zelo podobne lastnosti površine kot nov keramični del.The process according to the invention enables the modified and / or damaged and / or worn ceramic parts of different dimensions and shapes, which are eliminated from the production process due to different fiber tensions, uneven application of preparative oil, capillary breaks, appearance of loops on the bobbin and other physical and chemical changes on fibers leading to fiber inhomogeneity and low production yields in the synthetic man-made fiber industry and similar processes are subjected to controlled surface treatment with abrasive or sand-like particles (such as diamond balls or particles, metal balls or particles) and other abrasive materials in the form of beads or beads. particles that can be used as an abrasive for surface treatment of ceramic parts in order to achieve the same or. very similar surface properties to the new ceramic part.
Izum bomo podrobneje obrazložili na osnovi izvedbenega primera in pripadajočih slik, od katerih kaže:The invention will be explained in more detail on the basis of an embodiment and accompanying drawings, of which:

Keramični deli A različnih oblik in dimenzij s spremenjeno in/ali poškodovano površino so izpostavljeni kontroliranemu postopku obdelave površine z abrazivnim sredstvom B to je abrazivnimi delci ali pesku podobnimi delci (kot so diamantne kroglice oz. delci, kovinske kroglice oz.Ceramic parts A of various shapes and dimensions with altered and / or damaged surface are exposed to a controlled process of surface treatment with an abrasive agent B, i.e., abrasive particles or sand-like particles (such as diamond or metal beads,
delci) in mnogih drugih abrazivnih materialov v obliki kroglic oz. delcev, ki se lahko uporabijo kot abrazivno sredstvo za površinsko obdelavo keramičnih delov (slika 1).particles) and many other abrasive materials in the form of beads or beads. particles that can be used as an abrasive for surface treatment of ceramic parts (Figure 1).
Postopek obdelave keramičnih delov A, ki se uporabljajo v industriji umetnih sintetičnih vlaken, v namen recikliranja sestavljajo tri glavne io stopnje in sicer:The process of processing ceramic parts A used in the synthetic man-made fiber industry for recycling purposes consists of three main stages, namely:
- priprava keramičnega dela A, kjer se keramični del A s spremenjeno in/ali poškodovano površino preveri z optično povečevalno napravo povečave več kot 30x v smislu potrditve, da je površina keramičnega dela A sploh primerna za postopek obdelave z abrazivnim sredstvom B. V tej stopnji izločimo počene oz. tako poškodovane površine keramičnih delov A, ki bi povzročale, da postopek obdelave površine z abrazivnim sredstvom B ne bi vodil k končnemu produktu, ki bi imel enake oziroma zelo podobne lastnosti površine kot nov keramični del. Postopek optičnega pregleda je lahko ročen ali popolnoma avtomatiziran za detekcijo spremenjene in/ali poškodovane površine keramičnega dela v obliki razpok, prelomov, počenih robov, itd). Stopnja priprave keramičnega dela A je lahko tudi opuščena, vendar to rezultira v višjem izmetu v končni obdelavi in optični kontroli.- preparation of ceramic part A, where the ceramic part A with the modified and / or damaged surface is checked with an optical zoom magnification device more than 30x in order to confirm that the surface of ceramic part A is at all suitable for the abrasive treatment B. In this step we eliminate the broken ones. surfaces of ceramic parts A thus damaged, which would cause the surface treatment with abrasive agent B not to lead to a final product having the same or very similar surface properties as the new ceramic part. The scanning procedure can be manual or fully automated for the detection of altered and / or damaged surface of the ceramic part in the form of cracks, breaks, broken edges, etc.). The stage of preparation of ceramic part A may also be omitted, but this results in higher ejection in finishing and optical control.
- obdelava površine keramičnega dela A z abrazivnim sredstvom B, kjer se keramični del A, ki je že bil optično pregledan kot ustrezen za mehansko obdelavo površine vstavi v ležišče naprave za obdelovanje z abrazivnim sredstvom B. Naprava mora imeti natančno (npr. elektronsko ali ročno) vodeno (glede na prednastavljene procesne parametre) šobo C (prikazano na sliki 2), ki s kontrolirano usmerjenimi premiki preko statično vpetega io keramičnega dela A odstranjuje spremenjeno površino do stopnje, da ima obdelana površina karakteristiko površine kot jih izkazuje nov keramični del. Proces je lahko voden tudi tako, da se vpetje keramičnega dela B (na sliki 3) premika (npr. rotira) in da je premikanje vodene šobe C kontrolirano v relaciji vertikalnih in horizontalnih premikov z gibajočimi vpetjem in na takšen način obdeluje površino keramičnega dela A.- surface treatment of ceramic part A with abrasive agent B, where ceramic part A, which has already been scanned as suitable for mechanical surface treatment, is inserted into the bed of the abrasive treatment device B. The device must have a precise (eg electronic or manual) ) guided (according to preset process parameters) nozzle C (shown in Fig. 2), which with controlled directional movements via the statically clamped io ceramic part A removes the altered surface to the extent that the treated surface has the surface characteristic as evidenced by the new ceramic part. The process can also be controlled by moving (eg, rotating) the ceramic part B (in Fig. 3) and the movement of the water nozzle C is controlled in relation to the vertical and horizontal displacements by the movable grips, thus treating the surface of ceramic part A .
Pri nastavljanju delovnih parametrov delovanja naprave za obdelavo z abrazivnim sredstvom B (prikazani na slikah 2 in 3) so pomembni naslednji parametri;The following parameters are important when setting the operating parameters of the operation of an abrasive processing device B (shown in Figures 2 and 3);
(i) naklon D pihalne šobe C abrazivnega sredstva B, ki mora biti v območju med 0° in 180° v odvisnosti glede na vpadno pozicijo na površino keramičnega dela A, (ii) abrazivno sredstvo B kot pesek ali pesku podoben material (ustrezne dimenzije, oblike in strukture delcev); v procesu, ki je predmet izuma sta bila konkretno uporabljena dva različna materiala in sicer Korund 220 in Korund 70. Uporaba je odvisna glede na zahtevane končne karakteristike površine keramičnih delov A, (iii) velikost odprtine pihalne šobe C abrazivnega sredstva B (velikost odprtine je med 0.01 mm do 1 cm), (iv) hitrost oz čas, ki je potreben, da naprava za obdelavo z abrazivnim sredstvom B obdeluje določen segment površine keramičnega dela A (čas ki je potreben za obdelavo posamezne točke površine keramičnega dela A in zatem še vseh preostalih delov površine eden za drugim, tako da je obdelana celotna površina keramičnega dela je med 0.1 sekunde do 3 minut), (v) tlak zraka v napravi za obdelovanje z abrazivnim sredstvom B, ki potiska abrazivne delce na površino keramičnega dela A za doseganje učinka odstranjevanja spremenjene površine keramičnega dela A (tlak zraka je več kot 2 bara).(i) the inclination D of the nozzle B of the abrasive agent B, which must be in the range of 0 ° to 180 ° depending on the incident position on the surface of the ceramic part A; (ii) the abrasive agent B as a sand or sand-like material (suitable dimensions , particle shapes and structures); In the process of the invention, two different materials were specifically used, namely Corundum 220 and Corundum 70. The use depends on the required end characteristics of the surface of the ceramic parts A, (iii) the size of the opening of the blower nozzle C of the abrasive agent B (the size of the opening is between 0.01 mm and 1 cm), (iv) the speed or time required for the abrasive treatment device B to process a particular segment of the surface of ceramic part A (the time required to process a single point of the surface of ceramic part A and thereafter all remaining parts of the surface one after the other so that the entire surface of the ceramic part is machined between 0.1 seconds to 3 minutes), (v) the air pressure in the abrasive treatment device B which pushes the abrasive particles to the surface of ceramic part A to achieve the effect of removing the altered surface of ceramic part A (air pressure exceeding 2 bar).
- končna obdelava in optična kontrola, kjer se keramični del A, ki je bil izpostavljen kontrolirani abraziji površine obdela še z nežnim poliranjem v predelu kjer je bila odstranjena spremenjena površina (drgnjenje površine z umetnim ali bombažnim materialom (kot npr.- Finishing and optical inspection, where the ceramic part A exposed to controlled surface abrasion is further treated by gentle polishing in the area where the modified surface has been removed (rubbing the surface with artificial or cotton material (such as.
ščetka, krpica) z direktnim kontaktom z obdelano površino keramičnega dela). Po poliranju je možna uporaba ultrazvočne kopeli, za doseganje perfektne neprašne površine keramičnega dela A (ultrazvočni tretma ni zahteva ampak je opcija za doseganje boljših rezultatov v smislu čistosti površine keramičnega dela A).brush, cloth) by direct contact with the treated surface of the ceramic part). After polishing, it is possible to use an ultrasonic bath to achieve the perfect dust-free surface of ceramic part A (ultrasonic treatment is not a requirement but is an option for better results in terms of the purity of the surface of ceramic part A).
Zadnje dejanje je optična kontrola obdelane površine keramičnega dela z optično ali podobno povečevalno napravo z več kot 30x povečavo za potrditev da je površina keramičnega dela A enakih ali zelo podobnih karakteristik kot jih ima nov keramični del.The last step is the optical inspection of the treated surface of the ceramic part with an optical or similar magnifying device with more than 30x magnification to confirm that the surface of ceramic part A has the same or very similar characteristics as the new ceramic part.
V okvirju razvoja primernega postopka za obdelavo spremenjene is in/ali poškodovane površine keramičnih delov je bilo evaluiranih več različnih postopkov:Several different processes have been evaluated in the context of developing a suitable process for treating altered and / or damaged surfaces of ceramic parts:
