PDADMAC yawanci ana amfani da shi azaman flocculant kuma wani lokaci ana haɗe shi da algaecides. Wannan labarin zai yi bayani dalla-dalla game da fa'idodi da ƙimar aikace-aikacen aikace-aikacen da ake amfani da su na PolyDADMAC daga fannonin tsarin aikin sa, yanayin aikace-aikacen da ƙayyadaddun dabarun inganta ingantaccen maganin ruwa.

Abubuwan asali na PolyDADMAC

PolyDADMAC babban nau'in polymer ne na kwayoyin halitta tare da adadi mai yawa na ƙungiyoyin cationic a cikin tsarinsa na kwayoyin halitta, wanda zai iya yin tasiri sosai ga ƙwayoyin da aka dakatar da colloid a cikin ruwa. Babban halayensa sun haɗa da:

1. Ƙarfin cationicity: Yana iya da sauri neutralize barnatar da aka dakatar da barbashi a cikin ruwa.

2. Kyakkyawan narkewar ruwa: Yana da sauƙi don narke cikin ruwa kuma yana dacewa da aikace-aikacen kan layi.

3. Tsabar sinadarai: Yana iya kula da high-inganci flocculation yi a daban-daban pH jeri, oxidizing yanayi da kuma high inji karfi yanayi. PDADMAC yana da ƙarfin juriya na chlorine.

4. Ƙananan guba: Ya dace da ka'idodin kare muhalli kuma ya dace da maganin ruwan sha.

Hanyar aikin PolyDADMAC a cikin maganin ruwa

Yana destabilizes dakatar barbashi da barnatar da caje mai ruwa bayani abubuwa a cikin ruwa da flocculates su ta hanyar lantarki neutralization da adsorption bridging. Yana da tasiri mai mahimmanci a cikin decolorization, da kuma kawar da kwayoyin halitta.

PolyDADMACyana inganta aikin gyaran ruwa ta hanyoyi masu zuwa:

1. Cajin neutralization

Barbashi da aka dakatar da colloids a cikin ruwa yawanci suna ɗaukar tuhume-tuhume mara kyau, wanda ke haifar da ƙin yarda tsakanin ɓangarorin kuma yana da wahalar daidaitawa. Ƙungiyoyin cationic na PolyDADMAC na iya hanzarta kawar da caji mara kyau, rage ƙin electrostatic tsakanin barbashi, da haɓaka coagulation na barbashi.

2. Bridging sakamako

Tsarin kwayoyin halitta mai tsayin tsayi na PolyDADMAC mai girman danko yana ba shi damar samar da "gada" tsakanin ɓangarorin da yawa, yana haɗa ƙananan ƙwayoyin cuta zuwa manyan flocs, don haka inganta haɓakar lalata.

3. Ƙarfafa tasirin kamawa

PolyDADMAC na iya ƙarfafa "tsarin yanar gizo" wanda aka kafa ta hanyar inorganic coagulant a cikin maganin ruwa don kama kyawawan abubuwan da aka dakatar da su yadda ya kamata, musamman a cikin turbidity ko gurɓataccen ruwa.

Yanayin aikace-aikacen PolyDADMAC

1. Maganin ruwan sha

Ana amfani da PolyDADMAC azaman flocculant don cire turbidity, dakatarwar barbashi da kwayoyin halitta daga ruwan sha. A lokaci guda, saboda ƙarancin guba da halayen kariyar muhalli, yana iya cika ka'idodin amincin ruwan sha.

2. Maganin sharar ruwa

A cikin sharar gida da masana'antu magani, PolyDADMAC yawanci amfani don inganta sludge dewatering yi, rage danshi abun ciki na laka cake, da muhimmanci rage aiki halin kaka.

3. Tsaftace ruwan masana'antu

A cikin wutar lantarki, petrochemical da sauran masana'antu, ana amfani da PolyDADMAC don tsarkake ruwa na masana'antu kamar ruwan sanyi da ruwan tukunyar jirgi don rage haɓakawa da haɗarin lalata.

4. Samar da takarda da masana'anta

Ana amfani da PolyDADMAC azaman taimako na riƙewa da tacewa don haɓaka ƙimar riƙe zaruruwa da filaye a cikin tsarin yin takarda, yayin da rage abun ciki na abubuwan da aka dakatar a cikin ruwan sharar gida.

Dabarun inganta ingantaccen maganin ruwa tare da PolyDADMAC

1. Inganta sarrafa sashi

Matsakaicin adadin PolyDADMAC yana da alaƙa da alaƙa da tattarawa, rarraba girman barbashi da halayen gurɓatawar da aka dakatar a cikin ruwa. Haɓaka adadin ta hanyar gwajin kwalba na iya ƙara girman tasirin sa yayin gujewa yawan adadin da ke haifar da ƙarin farashi ko gurɓataccen ruwa na biyu.

2. Synergistic sakamako tare da inorganic flocculants

Amfani da PolyDADMAC a hade tare da inorganic flocculants (kamar polyaluminium chloride da aluminum sulfate) na iya haɓaka tasirin flocculation sosai. Bayan PolyDADMAC ya kawar da cajin saman ɓangarorin, ƙwayoyin flocculats na inorganic suna ƙara haɓaka flocs mafi girma ta hanyar tallatawa da lalata.

3. Inganta matakin sarrafa kansa na hanyoyin kula da ruwa

Tare da taimakon tsarin sarrafawa ta atomatik, ana iya samun sa ido na ainihi da daidaitawa na PolyDADMAC sashi don jimre wa canje-canje a cikin ingantaccen magani wanda ya haifar da canjin ingancin ruwa.

4. Inganta yanayin motsawa

Bayan ƙara PolyDADMAC, dace motsa tsanani da kuma lokaci iya bunkasa ta dispersibility da flocculation yadda ya dace. Yawan motsa jiki na iya haifar da flocs su karye, yayin da rashin isasshen motsawa zai rage tasirin hadawa.

5. Daidaita darajar pH

PolyDADMAC yana aiki mafi kyau a ƙarƙashin tsaka tsaki zuwa yanayin rashin ƙarfi na alkaline. Lokacin da ake kula da ruwan acidic ko alkaline sosai, daidaita ƙimar pH na jikin ruwa na iya inganta tasirin sa.

Amfanin PolyDADMAC

1. Babban inganci: Saurin samuwar flocs don inganta ingantaccen rarrabuwar ruwa mai ƙarfi.

2. Faɗin aikace-aikace: Ya dace da halaye na ruwa daban-daban, musamman ruwa tare da babban turbidity da babban abun ciki na kwayoyin halitta.

3. Kariyar muhalli: Ƙananan ƙwayar cuta da kuma biodegradability, daidai da bukatun kare muhalli.

A matsayin mai inganci sosaiflocculant, PolyDADMAC yana da amfani mai mahimmanci na aikace-aikacen a fagen maganin ruwa saboda ƙarfin cationicity, mai kyau ruwa mai narkewa da kuma amfani mai yawa. Ta hanyar ingantaccen tsari mai ma'ana da dabarun aiki, ana iya inganta ingantaccen magani a cikin tsarkakewar ruwan sha, najasa da ruwan masana'antu.
