Ka hana a me ka hoʻohana ʻana i ka waiʻona polyvinyl

Hoʻohana ʻia ka waiʻona polyvinyl i nā manawa he nui i ko mākou ola.Nui nā papa inoa o ka waiʻona polyvinyl a me ka hoʻohana ʻana i ka waiʻona polyvinyl.He kuleana koʻikoʻi ia i kā mākou hana a me ke ola.ʻAʻole maopopo loa kekahi poʻe e pili ana i ka hoʻohana ʻana i ka waiʻona polyvinyl, no laila, he aha ka hoʻohana ʻana i ka waiʻona polyvinyl?E nānā kākou!
He aha ka polyvinyl alcohol?
ʻO ka waiʻona polyvinyl kahi mea hoʻohuihui, ʻano kemika [C2H4O] N.Hiki ke hoʻoheheʻe ʻia i ka wai (ma luna o 95 ℃), hiki ke hoʻoheheʻe ʻia i ka dimethyl sulfoxide, insoluble i ka ʻaila, kerosene, ka aila mea kanu, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc.
ʻElua, ke kuleana o ka waiʻona polyvinyl.
Hoʻohana ʻia no ka hana ʻana i ka polyvinyl acetal, ka paipu kūpaʻa ʻaila a me ka vinylon, ka mea mālama lole, emulsifier, ka uhi pepa, adhesive, etc.
Ka hoʻokaʻawale ʻana o nā mea maka kemika
Hiki ke hoʻokaʻawale ʻia nā mea maka kemika i loko o nā mea kino a me nā mea kino kemika.
Ka hoʻokaʻawale ʻana o nā mea kino kemika
Hiki ke hoʻokaʻawale ʻia i nā alkanes a me kā lākou derivatives, alkenes a me kā lākou derivatives, alkynes a me nā derivatives, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydrides, esters, organic acids, carboxylate, carbohydrates, heterocyclic, nitriles, halogenates, aminoids, a me nā ʻāpana ʻē aʻe.
Ka hoʻokaʻawale ʻana o nā mea kino kemika
ʻO nā mea waiwai nui o nā huahana kemika inorganic he sulfur, sodium, phosphorus, potassium, calcium a me nā minela kemika ʻē aʻe (e ʻike i ka ʻoihana paʻakai inorganic) a me ka lanahu, ka aila, ke kinoea maoli a me ka ea, ka wai a pēlā aku.
He aha nā mea kino kemika
ʻO ka ʻoihana kemika organik ka pōkole o ka ʻoihana kemika organik, ʻike ʻia hoʻi ʻo ka ʻoihana synthesis organik.Hoʻokumu ʻia ma ka ʻaila, ke kinoea maoli, ka lanahu a me nā mea waiwai ʻē aʻe, ʻo ka hana nui o nā ʻano ʻoihana ʻoihana kūlohelohe.ʻO nā mea waiwai kūlohelohe kumu maoli ka hydrogen, carbon monoxide, methane, ethylene, acetylene, propylene, carbon four or more aliphatic hydrocarbons, benzene, toluene, xylene, ethylbenzene a pēlā aku.Mai ka aila maʻemaʻe, ka aila distillate a i ʻole ka haʻahaʻa carbon alkane cracking gas, refinery gas a me ke kinoea, ma hope o ka hoʻokaʻawale ʻana, hiki ke hana ʻia no nā kumu like ʻole o nā mea waiwai aliphatic hydrocarbon;Hiki ke hoʻokaʻawale ʻia nā mea ʻala mai ka ʻaila i hoʻololi ʻia o ka catalytic reforming, ka ʻaila mahā o ka haki ʻana o ka hydrocarbon a me ke kola lanahu o ka retorting lanahu.
