HEDP

Hydroxyethylidene diphosphonic acid (HEDP) imhando yeorganic phosphonic acid-based scale and corrosion inhibitor iyo inoumba complexes dzakagadzikana dzine ma ions akasiyana-siyana esimbi, akadai sesimbi, mhangura, uye zinc, uye inonyungudutsa ma oxides pamusoro pesimbi.

Inoramba ichishanda mukudzivirira ngura uye kuumbwa kwemakero kunyangwe pa250°C, inoramba yakagadzikana pamazinga epH akakwira, uye inoramba hydrolysis. HEDP inodzivirira zviri nani acids, alkalis, uye chlorine oxidation kupfuura mamwe organic phosphonic acids (nemunyu wavo).

Nhamba yeCAS: 2809-21-4

Zvakanakira

● Inoshandiswa zvakanyanya mumaindasitiri

● Inoratidza kugadzikana kwakanaka kunyangwe paine gasi re chlorine

● Inoratidza hunhu hwakanaka hwekudzivirira ngura kunyangwe paine zinc nedzimwe phosphates

● Inoshanda zvakanaka pakupisa kwakanyanya uye pH yakakwira

● Kana ichienzaniswa nedzimwe organic phosphonic acids (nemunyu), inopa simba guru rekudzivirira maasidhi, alkalis, uye chlorine oxidation.

● HEDP inosangana nemaion esimbi mumvura kuti igadzire machelate ane hexavalent. Nekuda kweizvozvo, HEDP inoratidza kudzivirira kwakanakisa kwechiyero uye mhedzisiro inooneka.

● HEDP inoratidza migumisiro yakanaka yekubatana kana ikashandiswa pamwe chete nemamwe makemikari ekurapa mvura.

● Nekuda kwekuchena kwayo kwakanyanya muchimiro chayo chakasimba, HEDP yakakodzera kushandiswa munguva yechando uye munzvimbo dzinotonhora zvakanyanya.

Mashandisirwo

Mvura:

● Kurapa mvura inotonhorera inotenderera mumaindasitiri: HEDP inodzivirira kuumbwa kwemakomba, ichidzivirira masisitimu emvura inotonhorera anotenderera mumaindasitiri kubva kumakomba nekuora. Inogadzira macomplexes akagadzikana ane maion akasiyana-siyana esimbi, anosanganisira iron, copper, aluminum, uye zinc, zvichiita kuti ive yakakodzera kubvisa ngura nemunyu usingasanganisike kubva mumaboiler nemapombi.

● Dziviriro yeBoiler neHeat Exchanger: Semushonga unodzivirira chikero nengura, HEDP inoshandiswa kuchengetedza maboiler neheat exchangers nekudzivirira kukwira kwemukati nengura, nokudaro ichirebesa hupenyu hwebasa remuchina.

● Mushonga weKubatanidza Masimbi weKubatanidza Masimbi Pasina Cyanide: Muindasitiri yeKubatanidza Masimbi, HEDP inoshanda semushonga wekubatanidza masimbi asina cyanide, zvichiwedzera kushanda zvakanaka kwekuisa masimbi uye kunaka kwechigadzirwa.

● Mushonga wekuchenesa weSimbi neSiri Simbi: HEDP inogona kushandiswa semushonga wekuchenesa wesimbi nedzisiri simbi, ichibvisa tsvina netsvina pamusoro pezvinhu zvakasiyana-siyana.

● Chinosimbisa uye Chinogadzirisa muIndasitiri yeKudhaya: MuIndasitiri yeKudhaya, HEDP inoshanda sechinosimbisa uye chinogadzirisa peroxide, ichivandudza mhando uye kugadzikana kwechigadzirwa.

Yakasimba:

● Zvinowedzerwa paMishonga Yemumba: Nekuda kwekuchena kwayo kwakanyanya, HEDP inogona kushandiswawo sekuwedzera mumakemikari emumba, akadai sezvizoro nemasipo, kuti ipe ruzivo rwuri nani rwemushandisi.

● Zvinhu zvekuchenesa muindasitiri yezvemagetsi: Muindasitiri yezvemagetsi, HEDP inoshandiswa kuchenesa zvikamu nemidziyo zvakanyatsonaka, zvichivandudza kushanda zvakanaka kwemidziyo uye kugadzikana kwayo.

● Mishonga inotakura utachiona mubazi rezvekurapa nerehutano: HEDP inoshanda semushonga wezvinhu zvine mwaranzi uye inoshandiswa zvakanyanya mukuongorora nekurapa zvirwere zvethyroid neitsvo.

Semushonga unodzivirira chikero, HEDP inowanzo shandiswa pahuwandu hwe1–10 mg/L; semushonga unodzivirira ngura, pa10–50 mg/L; uye semushonga wekuchenesa, pa1,000–2,000 mg/L. Inowanzo shandiswa pamwe chete ne polycarboxylic acid-based scale inhibitors nema dispersants.

Kurongedza uye Kuchengeta:

HEDP yemvura inoiswa mumadhiramu epurasitiki, rimwe nerimwe riine 30 kg kana 250 kg;

HEDP yakasimba inorongedzwa mumabhegi epurasitiki akarukwa nepolyethylene, ine huremu hwe25 kg pabhegi, kunyangwe kurongedza kuchigona kugadziriswa zvichienderana nezvinodiwa nevatengi.

Chengeta munzvimbo inotonhorera, ine mhepo inofefetera zvakanaka mukati, yakadzivirirwa kubva muhunyoro.

Kuchengetedzeka neDziviriro:

HEDP ine acidity; dzivisa kusangana nemaziso neganda. Kana ikapfapfaidzwa mumuviri, sukurudza nemvura yakawanda nekukurumidza.
