Me ka hoʻomohala ʻana o ke kaʻa ʻana o ke kūlanakauhale, ua ʻoi aku ka nui o ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā kala kala ʻole i ka pavement. ʻAʻole wale ka hana o ka hoʻonaninani ʻana i ka pavement kala, akā loaʻa pū kekahi i ka hana o ka ʻōlelo aʻo. ʻO ke kahua paheʻe kala ʻole he papa hana koʻikoʻi. Ua uhi ʻia kēia ʻano pavement me ka pale anti-slip kala ma luna o ka pavement i mea e waiwai ai ka pavement i ka hana anti-slip.
Hiki ke hoʻohana nui ʻia ka petroleum resin i nā ʻoihana like ʻole, Petroleum Resin e like me ka pena, ka pahu, a me nā mea ʻē aʻe. No ke aha i kaulana nui ai ka petroleum resin?
ʻElua ala nui o ka hoʻololi. ʻO kekahi ka hoʻololi hydrogenation, Petroleum Resin e hoʻohui i ka paʻa pālua i loko o ka mole resin petroleum, Petroleum Resin e hoʻomaikaʻi ai i kona kala a me ka paʻa anti-oxidation. Hiki ke hoʻomākaukau ʻia nā resins Petroleum me nā waiwai kūikawā ma ka hoʻohui ʻana i nā hui polar a i ʻole nā mea hoʻololi e like me ka monoolefin i nā mea maka.
Loaʻa ka hapa nui o ka C9 i nā pūhui hydrocarbon aromatic unsaturated e like me vinyl toluene, indene, methylstyrene, Petroleum Resin etc.
ʻO ke kaʻina hana hoʻomākaukau o ka resin petroleum C9 penei: ua hoʻomaʻamaʻa mua ʻia nā mea maka e wehe (bis) cyclopentadiene a me isoprene, Petroleum Resin no ka loaʻa ʻana o nā mea maka me ka hapa nui o 50%, Petroleum Resin a laila hoʻohui i kahi hydrocarbon aromatic diluent. ma lalo o ka pale o ka nitrogen, Petroleum Resin A laila e hoʻohui i ka mea hoʻoheheʻe AlCl3.
ʻO ke kūlana hoʻomohala o ka C9 petroleum resin production ma ka home a ma waho: ʻo ka hoʻomohala ʻana i ka ʻoihana petrochemical e hāʻawi i nā waiwai waiwai a me nā kumu waiwai no ka hana ʻana i ka petroleum resin, Petroleum Resin no laila ke ulu wikiwiki nei ka hana ʻana o ka petroleum resin i kekahi mau ʻāina hoʻomohala petrochemical.
