Abstract
Sposób polega na tym, że sproszkowany chitozan rozpuszcza się w wodzie aż do uzyskania 5% roztworu, do którego dodaje się 70 - 90% kwas octowy, a po utworzeniu półfabrykatu gwoździa śródszpikowego i przeprowadzeniu kąpieli koagulacyjnej i neutralizującej i półfabrykat poddaje się kąpieli sieciującej w roztworze utworzonym z 0,5 do 2% tripolifosforanu sodu i 0,5% do 3% Na3PO4, w czasie 24 - 48 godzin i temperaturze 50 - 140°C. Z kolei przeprowadza się proces suszenia w czasie od 6 do 10 dni. Na koniec przeprowadza się obróbkę powierzchniową półfabrykatu do postaci gwoździa śródszpikowego. Obróbkę powierzchniową prowadzi się aż do uzyskania powierzchni gwoździa śródszpikowego zawierającej co najmniej 20 - 40% pór o głębokości 0,1 mm do 1,0 mm.
