Chii chinonzi Polyaluminium Chloride?
Polyaluminium chloride, yakapfupikiswa sePAC, inorganic polymer mvura yekurapa mumiririri. Mhando idzi dzakakamurwa kuita mapoka maviri: kushandiswa kwemvura yekunwa mudzimba uye isiri-yemumba yekunwa kushandiswa kwemvura, imwe neimwe inoenderana nematanho akakodzera akasiyana. Chitarisiko chakakamurwa kuva mhando mbiri: mvura uye yakasimba. Nekuda kwezvakasiyana-siyana zvirimo mune mbishi zvinhu, kune misiyano mukutaridzika kweruvara uye mashandisiro ekushandisa.
Polyaluminium chloride haina ruvara kana yero yakasimba. Mushonga wayo imvura isina ruvara kana yero yebrown inoonekera, inonyungudika nyore mumvura uye inonyungudutsa doro, isinganyunguriki muanhydrous doro uye glycerol. Inofanira kuchengetwa munzvimbo inotonhorera, ine mhepo, yakaoma, uye yakachena. Panguva yekufambisa, zvinodikanwa kudzivirira kubva kumvura uye zuva rakananga, kudzivirira deliquescence, uye kubata nekungwarira panguva yekurodha uye kurodha kudzivirira kukuvara kwepakeji. Nguva yekuchengetedza yezvigadzirwa zvemvura mwedzi mitanhatu, uye yezvigadzirwa zvakasimba igore rimwe chete.
Zvishandiso zvekuchenesa mvura zvinonyanya kushandiswa kuchenesa mvura yekunwa, tsvina yemumaindasitiri, uye tsvina yemumadhorobha, sekubvisa simbi, fluorine, cadmium, kusvibiswa kweradioactive, uye mafuta anoyangarara. Inoshandiswawo muindasitiri yekuchenesa mvura yetsvina, sekudhinda uye kudhaya mvura yetsvina. Inoshandiswawo mukukandira chaiko, mushonga, kugadzira mapepa, rabha, kugadzira matehwe, peturu, indasitiri yemakemikari, uye dhayi. Polyaluminium chloride inoshandiswa sechinhu chekuchenesa mvura uye cosmetic raw material mukurapa kwepamusoro.
Polyaluminium chloridehas adsorption, coagulation, kunaya uye zvimwe zvivakwa. Iinewo kusagadzikana kwakashata, chepfu, uye inoora. Kana ikasaswa paganda netsaona, suka ipapo nemvura. Vashandi vekugadzira vanofanirwa kupfeka zvipfeko zvebasa, masiki, magurovhosi, uye bhutsu refu rerabha. Midziyo yekugadzira inofanirwa kuvharwa, uye kufefetedza kwewekishopu kunofanirwa kunge kwakanaka. Polyaluminium chloride inoora kana ichipisa pamusoro pe110 ℃, ichiburitsa hydrogen chloride gasi, uye pakupedzisira inoora kuita aluminum oxide; Inopindirana neasidhi kuita depolymerization, zvichikonzera kudzikira kwedigiri repolymerization uye alkalinity, inozopedzisira yashanduka kuita aluminiyamu munyu. Kudyidzana nealkali kunogona kuwedzera dhigirii repolymerization uye alkalinity, zvichizotungamira pakuumbwa kwealuminium hydroxide precipitate kana aluminate munyu; Kana yakasanganiswa nealuminium sulfate kana imwe multivalent asidhi munyu, kunaya kunogadzirwa nyore, izvo zvinogona kuderedza kana kurasikirwa zvachose nekuita coagulation.
