1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) — Choteteza Chogwira Ntchito Pakuchiza Madzi Amafakitale

1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP), yomwe ndi mankhwala oletsa dzimbiri komanso oletsa dzimbiri a m'gulu la organic phosphonic acid, yakhala mankhwala ofunikira kwambiri pochiza madzi m'mafakitale komanso kugwiritsa ntchito m'madera ambiri chifukwa cha kapangidwe kake kokhazikika ka mankhwala komanso magwiridwe antchito abwino kwambiri. Imateteza magwiridwe antchito a zida kwa nthawi yayitali komanso chitukuko chabwino cha mafakitale.

Ubwino waukulu wa HEDP uli mu kukana kutentha kwambiri, kukana asidi ndi alkali, komanso mphamvu yamphamvu ya chelating. Kapangidwe kake kapadera ka CP bond kamalimbana ndi hydrolysis ndipo kamasunga magwiridwe antchito okhazikika pansi pa kutentha kwakukulu mpaka 250℃ ndi pH yochuluka ya 2-12, ndi kukana kwapamwamba kwambiri kwa chlorine oxidation poyerekeza ndi zinthu zofanana za organic phosphonic acid. Magulu a bisphosphonic acid m'mamolekyu ake amatha kupanga ma chelate okhazikika a mphete okhala ndi ziwalo zisanu ndi chimodzi okhala ndi ayoni achitsulo monga calcium, magnesium, iron ndi copper, zomwe zimaletsa bwino kupangika kwa sikelo kuphatikiza calcium carbonate ndi calcium sulfate. Imapereka zotsatira zabwino kwambiri zoletsa sikelo ngakhale pamlingo wotsika ndipo imakhala ndi zotsatira zoyambira, ndi zotsatira zodabwitsa zogwirizana zikagwiritsidwa ntchito mu compound formulations.

Ili ndi njira zambiri komanso zosiyanasiyana zogwiritsira ntchito. M'mafakitale, imagwiritsidwa ntchito kwambiri m'madzi ozizira ozungulira, ma boiler apakati ndi otsika mphamvu, mapaipi opatsira mafuta m'munda wamafuta ndi mapaipi otumizira mafuta m'magetsi, mankhwala, zitsulo, feteleza wamankhwala ndi mafakitale ena, zomwe zimaletsa bwino kuyika kwa sikelo ndi dzimbiri, zimapangitsa kuti kutentha kugwire bwino ntchito komanso kukulitsa moyo wa zida. Mumakampani opanga nsalu ndi zopepuka, imagwira ntchito ngati chotsukira chachitsulo/chosakhala chachitsulo, chokhazikika cha peroxide komanso chotsukira utoto cha bleach ndi dyeing. Kuphatikiza apo, ingagwiritsidwe ntchito ngati chotsukira chamagetsi chopanda cyanide, chotsukira chapamwamba kwambiri chamakampani amagetsi komanso chowonjezera pazinthu zamagetsi zatsiku ndi tsiku. Ndi poizoni wochepa komanso wochezeka, imakwaniritsa zofunikira za zochitika zosiyanasiyana.

Kusankha HEDP kumatanthauza kusankha njira yothandiza, yokhazikika komanso yotsika mtengo. Imathetsa mavuto a kukula ndi dzimbiri ndi magwiridwe antchito apamwamba, imachepetsa ndalama zogwirira ntchito ndi kukonza, komanso imathandiza makina a mafakitale kusunga mphamvu ndikuchepetsa kugwiritsa ntchito, zomwe zimapangitsa kuti ikhale chida chothandizira chamankhwala chofunikira kwambiri popanga mafakitale amakono.
