DESCRIPTION A RESIN FOR ABRASIVE ELEMENTS AND A PRODUCTION METHOD FOR IT The present invention provides long-lasting corrosion properties, suitable for industrial, hand-held and personal use. where abrasive particles are coated in order to obtain abrasive elements that retain time resin that gives flexibility and elasticity to the substrate/support and relates to synthesis.
Onceki Teknik Asindirici elemanlar çesitli endüstriyel, evsel ve teknolojik uygulamalarda çok yaygin olarak kullanilmaktadir. Farkli kullanim alanlarinin olmasi nedeniyle, bu kullanim alanlarina göre farkli fiziksel ve kimyasal bilesimlere sahip olabilmekte ve farkli sekillerde veya büyüklerde tercih edilebilmektedir. Asindirici elemanlarin yaygin kullanimlari arasinda taslama, parlatma, kesme, delme, bileme ve zimparalama bulunmaktadir. Previous Technique Abrasive elements are very common in various industrial, domestic and technological applications. is used as Due to the different usage areas, this usage It can have different physical and chemical compositions according to its fields and can be used in different forms. or adults can be preferred. Common uses of abrasive elements These include grinding, polishing, cutting, drilling, sharpening and sanding.
Asindirici elemanlar çesitli amaçlar için sekillendirilebildiginden, bloklar, kayislar, diskler, tekerlekler, tabakalar, çubuklar ve gevsek taneler halinde üretilebilirler. Asindirici elemanlar; asindirici tanecikler ile birlikte dolgu maddeleri ve/veya baglayici malzemeler ve/veya bir alt tasiyici/katman (substrat) içermektedir. Içeriklerine ve üretim tekniklerine göre farkli sekillerde olabildiginden, asindirici elemanlar, baglanmis asindirici elemanlar ve kaplanmis asindirici elemanlar olarak iki ayri grupta siniflandirilabilmektedir. Teknikte baglanmis asindirici elemanlar asindirici taneciklerin dolgu maddeleri ve baglayici malzemeler ile birlikte karisimindan elde edilmektedir. Kaplanmis asindirici elemanlar ise, örnegin zimparada oldugu gibi, asindirici tanelerin bir alt katmana (substrata) baglanmis veya yapistirilmis halde bulunmaktadir. Burada alt katman kâgit, kumas, vulkanize fiber veya reçine olabilmektedir. Asindirici tanecikler kullanildiklari yüzey ve materyale göre farkli bilesenler örnegin cam, çakmaktasi, granat, alüminyum oksit, silisyum karbür olabilir. As abrasive elements can be shaped for various purposes, blocks, belts, discs, they can be produced as wheels, sheets, rods and loose grains. Caustic workers; abrasive particles together with fillers and/or binder materials and/or a substrate. their ingredients and production techniques abrasive elements, bonded abrasive elements and coated abrasive elements can be classified in two separate groups. in technique bonded abrasive elements fillers and binders of abrasive particles It is obtained from the mixture with the materials. Coated abrasive elements are As in sandpaper, for example, abrasive grains are bonded to a substrate. or attached. Here the substrate is paper, fabric, vulcanized fiber. or resin. Abrasive particles are used according to the surface and material. different components can be eg glass, flint, garnet, aluminum oxide, silicon carbide.
Teknikte bilinen yöntemler ile 'üretilen kaplanmis asindirici elemanlar (örnegin zimparalar) yeteri kadar esnek olmadigindan, katlanma-bük'ülme sonrasinda kirilmalar ve dökülmeler gözlenmektedir.

Plastiklestirici ajanin reçine içerisindeki rolü çok önemlidir. Bulus ile gelistirilen reçine fenolik yapida oldugundan; sahip oldugu vinil gruplari ve sekillendirilebilir pi baglari nedeniyle en az bir plastiklestirici ajan tercihen polivinil alkolleri (PVA) içermektedir. Polivinil alkoller (PVA) tek baslarina veya yukarida belirtilen diger plastiklestiriciler ile kombinasyon halinde kullanilabilmektedir. Polivinil alkoller sahip olduklari alkol gruplari ile reçinedeki fenolik yapida bulunan hidroksil gruplarina uyum saglamakta ve bu fenolik yapiya hidrojen baglari ile homojen bir sekilde katilmaktadir. Kullanilan PVA`nin hidroliz sayisi, polimer uzunlugu, agirligi, safligi ve kullanim miktari reçinenin ve asindirici elemanlarin özelliklerini dogrudan etkilemektedir. Bu nedenle uygun PVA modifikasyonu saglanmasi büyük önem tasimaktadir. Bahsedilen modifikasyon için PVA'nin kullanim miktari toplam agirliga göre agirlikça %01 ila 300 araliginda (tercihen %02 ila %20 araliginda, daha tercihen %05 ila %5 araliginda) olmaktadir. PVA karakterinin baskin olmasinin istenmesi durumunda PVA”nin kullanim miktari toplam agirliga göre agirlikça % 50 ila %300 araliginda olmaktadir. PVA'nin kullanim miktarinin yüksek oranlarda olmasi, reçinedeki fenolik polimerden gelen termal ve mekanik 'özelliklerin baskilanmasina sebep olabilmektedir. Bahsedilen modifikasyon için PVAinin hidroliz yüzdesinin yüksek olmasi gerekmektedir. Yüksek hidroliz yüzdesi sayesinde reçinedeki fenolik yapinin sahip oldugu hidroksil sayisi artmakta ve yüzeydeki fiberlerin sahip oldugu elektronegatif gruplar ile daha iyi ve daha esnek hidrojen baglari olusturmaktadir. Yüksek hidroliz yüzdesine sahip PVA zincirleri reçinedeki fenol formaldehit polimer zincirleri ile daha çok etkilesime geçmektedir.

Resin of plasticizing agent its role in it is very important. Since the resin developed with the invention has a phenolic structure; at least one plasticizer due to its vinyl groups and formable pi bonds the agent preferably includes polyvinyl alcohols (PVA). Polyvinyl alcohols (PVA) alone or in combination with other plasticizers mentioned above can be used. Polyvinyl alcohols are phenolic compounds in the resin with their alcohol groups. It adapts to the hydroxyl groups in the structure and hydrogen is attached to this phenolic structure. It joins homogeneously with its bonds. The number of hydrolysis of PVA used, polymer length, weight, purity and amount of use of the resin and abrasive elements directly affect its properties. Therefore, providing appropriate PVA modification is of great importance. The amount of use of PVA for the mentioned modification is the total in the range of 01 to 300% by weight (preferably between 02% and 20% by weight, more preferably in the range of 05 to 5%). Requesting the PVA character to be dominant In the case of PVA, the usage amount is 50% to 300% by weight, according to the total weight. is in the range. The high rate of use of PVA, the cause suppression of the thermal and mechanical properties from the phenolic polymer. can happen. High percentage of hydrolysis of PVA for the mentioned modification. required. Thanks to the high percentage of hydrolysis, the phenolic structure in the resin has The number of hydroxyls increases and the electronegative groups of the fibers on the surface increase. It forms better and more flexible hydrogen bonds. Has a high percentage of hydrolysis PVA chains interact more with phenol formaldehyde polymer chains in the resin. passes.

PVA' nin polimer uzunlugu kisaldikça (düsük polimerlesme derecesine sahip) eklendigi reçineye ideal baglayicilik özelligini kazandirmamaktadir. Dolayisiyla PVA'nin yukarida belirtilen sartlarda ve özelliklerde reçineye eklenmesi gerekmektedir. As the viscosity of the resin increases, problems occur during use and preferably other materials added (eg filler material) are not compatible with the resin. causes. The shorter the polymer length of PVA, the lower the polymerization degree. does not impart the ideal binding property to the resin to which it is added. Therefore PVA must be added to the resin under the conditions and properties specified above.
