ʻOkoʻa ma waena o ka kānana PP a me PE Sintered

Hana ʻia ka pahu kānana sintered PP mai ka pauka polypropylene a ua ʻike ʻia no kona kūpaʻa kemika maikaʻi loa, kūpaʻa wela, a me ka ikaika mechanical. He koho kūpono ia e hiki ke hoʻohana ʻia no ka kānana ʻana i nā ʻano wai like ʻole, me nā waikawa, alkalis, a me nā mea hoʻoheheʻe organik. ʻO ka nui o ka pore o ka pahu kānana sintered PP maʻamau mai 0.2 a 100 microns, e kūpono ana no nā noi kānana coarse a me fine. Eia kekahi, he kiʻekiʻe kona ʻili a me ka porosity, e hiki ai iā ia ke mālama i nā nui o nā ʻāpana.

ʻO ka pahu kānana sintered PE, ma ka ʻaoʻao ʻē aʻe, ua hana ʻia mai ka pauka polyethylene a he haʻahaʻa kona kūpaʻa kemika a me ka wela ma mua o ka pahu kānana sintered PP. Eia nō naʻe, he porosity kiʻekiʻe kona, ʻo ia ka mea e lilo ai i koho maikaʻi loa no nā noi kānana e koi ana i nā kahe kahe kiʻekiʻe a me nā emi haʻahaʻa haʻahaʻa. ʻO ka nui o kona pore maʻamau mai 0.1 a 70 microns, kahi kūpono no nā noi kānana maikaʻi.

I ka hōʻuluʻulu manaʻo, ʻo ka pahu kānana sintered PP a me ka pahu kānana sintered PE ʻelua ʻano o nā pahu kānana i kūpono no nā ʻano noi kānana like ʻole. He kūpono ke kumukūʻai o ka pahu kānana sintered PP, kūpaʻa i nā kemika a me ka wela, a kūpono no nā noi kānana coarse a me nā noi kānana maikaʻi, ʻoiai ʻo ka pahu kānana sintered PE he porosity kiʻekiʻe, a kūpono no nā noi kānana e koi ana i nā kahe kiʻekiʻe a me nā hāʻule haʻahaʻa.
