ʻO Polyaluminum Chloride (Pac) 25% -30% No ka mālama wai
ʻO ka Polyaluminum Chloride (PAC) kahi mea hou a maikaʻi loa i hoʻolālā ʻia no ka hoʻomaʻemaʻe wai. ʻIke ʻia ʻo Polyaluminium, ʻo PAC kahi polymer inorganic wai-soluble e hana ma ke ʻano he coagulant. Me kāna haku mele AlCl3 a me Al(OH)3 kū hoʻokahi, ʻoi aku ka pale ʻana o ka mea a hoʻopili i nā colloids a me nā ʻāpana i ka wai. He ʻoi aku ka maikaʻi ma ka hoʻopau ʻana i nā mea ʻawaʻawa micro-toxic a me nā ion metala kaumaha, i kūpono no ka hoʻomaʻemaʻe wai.

Potassium Carbonate99% No ka ʻoihana Inorganic
Loaʻa i ka potassium carbonate kahi ʻano kemika o K2CO3 a me ke kaumaha molekala o 138.206. He mea anoano ia me ka nui o ka hoohana a me ka hoohana ana. ʻO kēia keʻokeʻo keʻokeʻo crystalline pauka he 2.428g / cm3 a me kahi helu hoʻoheheʻe o 891 ° C, e lilo ia i mea hoʻohui kūikawā no nāʻoihana likeʻole. Loaʻa iā ia kekahi mau mea kupaianaha e like me ka solubility i ka wai, ke kumu o kāna ʻano wai, a me ka hiki ʻole ke hoʻoheheʻe i ka ethanol, acetone, a me ka etera. Eia kekahi, ʻo kona hygroscopicity ikaika e hiki ai ke komo i ka carbon dioxide a me ka wai i ka lewa, e hoʻohuli iā ia i ka bicarbonate potassium. No ka mālama ʻana i kona kūpaʻa, he mea koʻikoʻi ia e mālama a hoʻopaʻa i ka potassium carbonate ma kahi ʻano ʻeleʻele.

ʻO Sodium Cyanide 98% No ka Pesticide
ʻO ka sodium cyanide, ʻike ʻia hoʻi ʻo kaempferol a i ʻole kaempferol sodium, he pūhui ikaika me ka nui o nā noi. ʻO ka sodium cyanide kona inoa Kina, e hōʻike ana i kona kaulana i nā ʻoihana like ʻole a puni ka honua. ʻO ka pūhui, me kahi ʻano kemika o NaCN a me ke kaumaha molekala o 49.007, ua huki nui ʻia no kāna mau waiwai kūʻokoʻa a me ka versatility.
ʻO ka helu helu CAS o ka sodium cyanide he 143-33-9, a ʻo ka helu inoa EINECS he 205-599-4. He pauda crystalline keʻokeʻo me kahi helu heheʻe o 563.7°C a me kahi helu hoʻolapalapa o 1496°C. ʻO kona hoʻoheheʻe wai a hiki ke hoʻoheheʻe ʻia ʻo 1.595 g/cm3 e maʻalahi ke hoʻohana i nā noi like ʻole. E like me ka hele ʻana, kū ka sodium cyanide i kona ʻano pauka keʻokeʻo keʻokeʻo keʻokeʻo, e hoʻohui ana i kahi paʻi o ka nani i kekahi kaʻina hana.
Aloha, hele mai e nīnau i kā mākou huahana!
