Raws li qhov sib txawv daim ntawv cog lus, nws muab faib ua hlau daim ntawv cog lus, resin daim ntawv cog lus, daim ntawv cog lus ceramic thiab electroplating daim ntawv cog lus pob zeb diamond abrasive cov cuab yeej. Resin polishing ncoo yog lub pob zeb diamond sib tsoo cov cuab yeej nrog cov duab zoo, uas yog ua los ntawm cov hmoov nplej ua cov khoom sib txuas thiab ntxiv nrog cov khoom muab tub lim los ntawm kev kub nias, hardening thiab machining txheej txheem. Vim nws cov elasticity zoo, cuam tshuam tsis kam, tus kheej zoo -sharpening, thiab siab sib tsoo efficiency, daim ntawv abrasive no tau nrov thiab siv hauv kev lag luam machining. Ntawm ntau hom kev sib tsoo pob zeb diamond sib tsoo cov cuab yeej tam sim no tsim, cob-bonded abrasives account rau qhov loj tshaj plaws. Hauv cov teb chaws txawv teb chaws, 80 feem pua -90 feem pua ntawm cov cemented carbide workpieces tau ua tiav nrog cov cuab yeej sib tsoo no, thiab nws tau maj mam hloov cov cuab yeej silicon carbide sib tsoo. Ntau yam thiab cov khoom tsim tawm ntawm cov khoom siv pob zeb diamond polishing pads kuj tau nce xyoo los ntawm xyoo, qhov zoo tau raug txhim kho tas li, thiab daim ntawv thov tau nce zuj zus. Tam sim no, cov ntaub ntawv cog lus siv hauv pob zeb diamond abrasive cov cuab yeej feem ntau suav nrog phenolic resin, polyimide resin thiab 11-10 black bakelite hmoov, thiab lwm yam. Phenolic resin, dawb los yog lub teeb daj translucent hmoov, yooj yim nqus noo noo thiab agglomerate hauv huab cua, Lub ntiajteb txawj nqus 1.25g ib cubic centimeter, soluble hauv cawv thiab acetone. Polyimide resin yog cov hmoov daj daj tsaus nti ntawm chav tsev kub. Nws tuaj yeem tswj xyuas cov khoom zoo ntawm 310-340 degrees Celsius. Qhov ceev yog 1.4g cubic centimeter. Lub zog 110Mpa yog ib hom tshiab ntawm cov khoom siv nrog cov cua sov zoo. 11-10 Dub Bakelite hmoov yog compression molding hmoov ua los ntawm phenolic resin raws li ib tug binder, ntxiv ntoo hmoov, mineral fillers thiab lwm yam additives los ntawm kev sib tov, dov, crushing thiab lwm yam txheej txheem. Lub hardener siv nyob rau hauv daim ntawv cog lus resin yog urotropine, lub npe scientific yog hexamethylenetetramine, uas yog dawb crystalline hmoov los yog tsis muaj xim thiab ci siv lead ua. Cua sov tsis yaj thiab sublimates, thiab nyob rau tib lub sij hawm ib nrab decomposes. Nws qhov ceev yog 1.27g ib cubic centimeter, yooj yim nqus dej noo thiab agglomerate, soluble hauv dej thiab ethanol, cov kua aqueous yog alkaline. Nws decomposes rau hauv ammonia thiab formaldehyde nyob rau hauv cua sov, uas yog irritating rau ntawm daim tawv nqaij. Nws yog ib qho hardener rau thermoplastic phenolic resins.
