He aha nā pōmaikaʻi a me nā pōʻino o ka hoʻohui ʻana i ka hydrotalcite i ka calcium zinc stabilizers?

ʻO Hydrotalc kahi mea waiwai nui no ka calcium zinc stabilizers. He hale kūikawā ko Hydrotalc a me nā waiwai, a ʻo kāna mau waiwai kumu he alkalinity a me multi porosity, me ka hana kūikawā a me ka maikaʻi. Hiki iā ia ke komo pono i ka hydrogen chloride i hoʻokuʻu ʻia i ka wā o ka hoʻohaʻahaʻa ʻana o PVC, e hoʻolohi i ka hopena catalytic ponoʻī o ka hydrogen chloride ma PVC resin, a hana ma ke ʻano he mea hoʻoheheʻe waika, i ʻike ʻia hoʻi ʻo ka thermal stability. Hoʻohana maʻamau ia e like me ka thermal stabilizer.
Loaʻa i ka Hydrotalc nā mea maikaʻi o ke aniani maikaʻi, ka insulation, ka pale ʻana i ka wā, a me ke kaʻina hana. ʻAʻole ia i hoʻohaumia ʻia e nā sulfides, non-toxic, a hiki ke hana synergistically me nā mea hoʻopaʻa wela e like me ke kopa zinc a me ka tin organic. He ʻano hoʻohiki maikaʻi loa ia o ka mea hoʻopaʻa wela kōkua non-toxic.
Hoʻopili ʻia ke ʻano o ka hydrotalcite me kahi spacing interlayer nui o 0.76-0.79nm, a he ʻāpana kikoʻī nui kona, e hiki ai i kāna mau pūʻulu hydroxyl ili ke hana piha me ka hydrogen chloride a he hopena maikaʻi i nā stabilizers.
ʻO nā hemahema o ka hydrotalcite:
1. Ma ke ʻano o ka keʻokeʻo mua, ʻaʻohe hopena o ka hydrotalcite i ka hoʻomaikaʻi ʻana i ka kala mua o PVC a i ʻole i ka hui pū ʻana me ka ʻōnaehana zinc calcium. Ma hope o ka ʻelemakule i ka umu wela 180 ℃, ʻulaʻula ka waihoʻoluʻu.
2. Ma ke kūpaʻa o ka ʻulaʻula ʻo Congo, hiki i ka hana hoʻokahi o ka hydrotalcite ke hoʻomaikaʻi i ka manawa kūpaʻa wela o PVC, a me ka hoʻonui ʻana i ka nui o ka hoʻohui, hōʻike ka manawa paʻa wela o PVC i ka piʻi nui ʻana, akā ʻaʻole nui ka piʻi.
3. Ke hoʻohana ʻia ka hui pū ʻana o ka hydrotalcite a me ka calcium zinc system ma ke ʻano he thermal stabilizer, ʻoi aku ka maikaʻi o ka manawa kūpaʻa wela o PVC, a ʻoluʻolu hoʻi ke ʻano o ka hoʻonui ʻana i ka manawa me ka hoʻonui ʻana i ka nui. No laila, pono e hoʻokaʻawale ʻia ka dihydroxy metala hydroxides e like me nā stabilizers thermal auxiliary lōʻihi, hiki ke hoʻonui i ka manawa paʻa wela o PVC. No laila, i ka hoʻohui ʻana i ka calcium zinc stabilizers, hydrotalcite kekahi o nā mea waiwai nui.
