HEDP

Hydroxyethylidene diphosphonic acid (HEDP) ndi chinthu choletsa dzimbiri chomwe chimachokera ku phosphonic acid chomwe chimapanga zinthu zokhazikika zokhala ndi ma ayoni osiyanasiyana achitsulo, monga chitsulo, mkuwa, ndi zinc, ndikusungunula ma oxide pamwamba pa zitsulo.

Imakhalabe yothandiza poletsa dzimbiri ndi kupanga mamba ngakhale pa 250°C, imakhala yokhazikika pamlingo wapamwamba wa pH, ndipo imalimbana ndi hydrolysis. HEDP imalimbana bwino ndi ma acid, alkalis, ndi chlorine oxidation kuposa ma organic phosphonic acid ena (ndi mchere wawo).

Ubwino

● Amagwiritsidwa ntchito kwambiri m'mafakitale

● Imaonetsa kukhazikika bwino ngakhale pakakhala mpweya wa chlorine

● Imaonetsa mphamvu zabwino zoletsa dzimbiri ngakhale itakhala ndi zinc ndi ma phosphate ena

● Imagwira ntchito bwino kutentha kwambiri komanso pH yambiri

● Poyerekeza ndi ma organic phosphonic acid ena (ndi mchere), imapereka kukana kwakukulu kwa ma acid, alkali, ndi chlorine oxidation.

● HEDP imachitapo kanthu ndi ma ayoni achitsulo m'madzi kuti ipange ma chelate a hexavalent. Chifukwa chake, HEDP imasonyeza kuletsa bwino kwa sikelo komanso zotsatira zowoneka bwino.

● HEDP imasonyeza zotsatira zabwino zogwirizana ikagwiritsidwa ntchito limodzi ndi mankhwala ena oyeretsera madzi.

● Chifukwa cha kuyera kwake kwakukulu mu mawonekedwe ake olimba, HEDP ndi yoyenera kugwiritsidwa ntchito nthawi yozizira komanso m'malo ozizira kwambiri.

Mapulogalamu

Madzi:

● Kuchiza madzi ozizira ozungulira mafakitale: HEDP imaletsa bwino kupangika kwa mamba, kuteteza makina ozizira ozungulira mafakitale ku mamba ndi dzimbiri. Imapanga ma complexes okhazikika okhala ndi ma ayoni osiyanasiyana achitsulo, kuphatikizapo chitsulo, mkuwa, aluminiyamu, ndi zinki, zomwe zimapangitsa kuti ikhale yoyenera kuchotsa dzimbiri ndi mchere wosapangidwa kuchokera ku ma boiler ndi mapaipi.

● Chitetezo cha Boiler ndi Kutentha: Monga choletsa sikelo ndi dzimbiri, HEDP imagwiritsidwa ntchito kuteteza ma boiler ndi kutentha poletsa kukulitsa ndi dzimbiri mkati, motero imawonjezera nthawi yogwirira ntchito ya zida.

● Chothandizira Kukonza Ma Electroplating Opanda Cyanide: Mu makampani opanga ma electroplating, HEDP imagwira ntchito ngati chothandizira kukonza ma electroplating opanda cyanide, zomwe zimapangitsa kuti ma plating agwire bwino ntchito komanso kuti zinthu ziyende bwino.

● Chotsukira cha Zitsulo ndi Zosakhala Zitsulo: HEDP ingagwiritsidwe ntchito ngati chotsukira cha zitsulo ndi zosakhala zitsulo, kuchotsa dothi ndi zonyansa pamwamba pa zipangizo zosiyanasiyana.

● Chokhazikika ndi Chokhazikika mu Makampani Opaka Utoto: Mu makampani opanga utoto, HEDP imagwira ntchito ngati chokhazikika komanso chokhazikika cha peroxide, ndikukweza ubwino ndi kukhazikika kwa zinthu.

Yolimba:

● Zowonjezera pa Mankhwala a Pakhomo: Chifukwa cha kuyera kwake kwakukulu, HEDP ingagwiritsidwenso ntchito ngati zowonjezera mu mankhwala a pakhomo, monga zodzoladzola ndi sopo, kuti ipereke mwayi wabwino kwa ogwiritsa ntchito.

● Zotsukira m'makampani opanga zamagetsi: Mumakampani opanga zamagetsi, HEDP imagwiritsidwa ntchito kuyeretsa zida ndi zida zolondola, zomwe zimapangitsa kuti zida zizigwira ntchito bwino komanso zikhazikike.

● Mankhwala othandizira odwala m'magawo azachipatala ndi azaumoyo: HEDP imagwira ntchito ngati mankhwala othandizira zinthu zowononga ma radiation ndipo imagwiritsidwa ntchito kwambiri pozindikira ndi kuchiza matenda a chithokomiro ndi impso.

Monga choletsa sikelo, HEDP nthawi zambiri imagwiritsidwa ntchito pamlingo wa 1–10 mg/L; ngati choletsa dzimbiri, pa 10–50 mg/L; ndipo ngati chotsukira, pa 1,000–2,000 mg/L. Nthawi zambiri imagwiritsidwa ntchito limodzi ndi zoletsa ndi zotulutsa sikelo zochokera ku polycarboxylic acid.

Kulongedza ndi Kusunga:

Madzi a HEDP amapakidwa m'madiramu apulasitiki, ndipo iliyonse imakhala ndi 30 kg kapena 250 kg;

HEDP yolimba imapakidwa m'matumba opangidwa ndi pulasitiki okhala ndi polyethylene, ndi kulemera konse kwa 25 kg pa thumba lililonse, ngakhale kuti ma phukusi amatha kusinthidwa malinga ndi zosowa za makasitomala.

Sungani pamalo ozizira, opumira bwino mkati, otetezedwa ku chinyezi.

    • Kodi ndingasankhe bwanji mankhwala oyenera kugwiritsa ntchito?

    Mungathe kutiuza momwe ntchito yanu ikugwiritsidwira ntchito, monga mtundu wa dziwe losambira, mawonekedwe a madzi otayira m'mafakitale, kapena njira yoyeretsera yomwe ilipo panopa.

    Kapena, chonde perekani mtundu kapena chitsanzo cha chinthu chomwe mukugwiritsa ntchito panopa. Gulu lathu laukadaulo lidzakupangirani chinthu choyenera kwambiri kwa inu.

    Mungathenso kutitumizira zitsanzo kuti zikawunikidwe mu labotale, ndipo tidzapanga zinthu zofanana kapena zabwino malinga ndi zosowa zanu.

     

    Kodi mumapereka ntchito za OEM kapena zachinsinsi?

    Inde, timathandizira kusintha kwa zinthu polemba zilembo, kulongedza, kupanga, ndi zina zotero.

     

    Kodi zinthu zanu zili ndi satifiketi?

    Inde. Zogulitsa zathu zili ndi satifiketi ya NSF, REACH, BPR, ISO9001, ISO14001 ndi ISO45001. Tilinso ndi ma patent azinthu zopangidwa mdziko lonse ndipo timagwira ntchito ndi mafakitale ogwirizana nawo poyesa SGS ndikuwunika mpweya.

     

    Kodi mungatithandize kupanga zinthu zatsopano?

    Inde, gulu lathu laukadaulo lingathandize kupanga mafomula atsopano kapena kukonza zinthu zomwe zilipo kale.

     

    Kodi zimatenga nthawi yayitali bwanji kuti muyankhe mafunso?

    Yankhani mkati mwa maola 12 pa masiku ogwira ntchito, ndipo funsani kudzera pa WhatsApp/WeChat ngati mukufuna zinthu zofunika mwamsanga.

     

    Kodi mungapereke zambiri zonse zotumizira kunja?

    Ikhoza kupereka zambiri zonse monga invoice, mndandanda wa zonyamula katundu, bilu ya katundu, satifiketi yochokera, MSDS, COA, ndi zina zotero.

     

    Kodi ntchito yogulitsa pambuyo pa malonda imaphatikizapo chiyani?

    Perekani chithandizo chaukadaulo pambuyo pa malonda, kusamalira madandaulo, kutsatira njira zoyendera, kubwezeretsanso kapena kulipira mavuto aubwino, ndi zina zotero.

     

    Kodi mumapereka malangizo ogwiritsira ntchito mankhwala?

    Inde, kuphatikizapo malangizo ogwiritsira ntchito, chitsogozo cha mlingo, zida zophunzitsira zaukadaulo, ndi zina zotero.
