ʻO ka ʻeleʻele kalapona, he kalapona amorphous, māmā, ʻoluʻolu a maikaʻi loa ka pauka ʻeleʻele, hiki ke hoʻomaopopo ʻia ʻo ka lalo o ka ipuhao.
He huahana ia i loaʻa ma ka hoʻopau piha ʻole ʻana a i ʻole ka decomposition wela o nā mea kalapona e like me ka lanahu, ke kinoea maoli, ka aila kaumaha, a me ka aila wahie ma lalo o ke kūlana o ka lawa ʻole o ka ea.
Loaʻa i nā ʻakika resin resin nā kaulahao pālua a me nā genes carboxyl-active, me nā paʻa pālua i hoʻohui ʻia a me nā hopena hui carboxyl maʻamau. Ma waho aʻe o ka prone i ka oxidation a me ka isomerization, ʻo ka rosin he mau mea hoʻopaʻa paʻa pālua e like me ka disproportionation, hydrogenation, hoʻohui, a me ka polymerization. Ma ka manawa like, loaʻa iā ia nā hopena carboxyl e like me ka esterification, alcoholization, hoʻokumu paʻakai, decarboxylation, a me aminolysis. .
ʻO nā resine petroleum (hydrocarbon resin) he resin thermoplastic i hana ʻia e ka pretreatment, polymerization, distillation a me nā kaʻina hana ʻē aʻe o nā ʻāpana C5 a me C9 i hana ʻia e ka petroleum cracking. ʻAʻole ia he polymer kiʻekiʻe, akā he polymer kaumaha haʻahaʻa ma waena o 300-3000.
Ua hoʻokumu mākou i kā mākou uea metala calcium i kēia makahiki, ʻO kā mākou ʻikepili uea metala calcium e like me kēia no kāu kuhikuhi:
Noi Nui: ʻO ka uea metala calcium ka mea maka o ka uea kumu calcium
Uea Rod Calcium me ke kaula ole
Hoʻohana nui ʻia kā mākou ʻano hou C5 Petroleum resin 6288S i loko o ka ʻoihana pena kiʻi wela wela wela wela. ʻO nā pōmaikaʻi nui e like me kēia:
20% nā pele aniani i hui ʻia
NĀ MEA: C5 Petropols, EVA, PE wax, titanium dioxide, nā mea kānana.
IKE: Pauda
