ʻO ka "hale kūʻai maʻamau" aʻu e kamaʻilio nei, ʻaʻole ia he hale liʻiliʻi, ʻeleʻele, ʻaʻole hoʻi he haʻahaʻa haʻahaʻa. Pono ia he wahi e malu ai mai ka makani a me ka ua, ka ea makani maikai, ka mahana paa, a me ke kinoea kino ino—e like me ka hale waiho maloo no ka malama ana i ka laiki a me ka palaoa. Inā ʻoluʻolu a me ka lā o ka hale kūʻai, ʻaʻole wale ka resin petroleum, akā e hoʻopau maʻalahi kekahi mea i ka manawa. No laila, pehea ka lōʻihi o ka Petroleum Resins i loko o kahi hale kūʻai maʻamau kūpono me ka ʻole o ka pōʻino?
ʻO ka hoʻomākaukau ʻana o ka Calcium Metal ka mea nui e pili ana i ke ʻano hōʻemi, ke ʻano electrolysis a me ka hoʻomaʻemaʻe calcium. Ma muli o ka ikaika loa o ka Calcium Metal, ua hana nui ʻia e ka electrolytic molten calcium chloride a i ʻole calcium hydroxide i ka wā ma mua. I nā makahiki i hala iho nei, ua lilo ke ʻano hoʻohaʻahaʻa i ke ʻano nui o ka hana ʻana i ka Calcium Metal.
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
