Sodium Tripolyphosphate (STPP) | 7758-29-4
Products Description
Sodium tripolyphosphate (STP, dzimwe nguva STPP kana sodium triphosphate kana TPP) inorganic compound ine formula Na5P3O10. Sodium triphosphate ndiyo sodium munyu wepolyphosphate penta-anion, inova iyo conjugate base ye triPhosphoric Acid.Sodium tripolyphosphate inogadzirwa nekupisa musanganiswa we stoichiometric weDisodium phosphate, Na2HPO4, uye Monosodium Phosphate, NaH2PO4, pasi pemamiriro akanyatsodzorwa.
Iko kushandiswa kweSodium tripolyphosphate kunosanganisira kuishandisa sekuchengetedza. Sodium Tripolyphosphate STPP inogona kushandiswa kuchengetedza zvikafu zvakaita senyama tsvuku, huku, nehove dzegungwa, zvichivabatsira kuchengetedza hunyoro uye unyoro. Chikafu chemhuka uye chikafu chemhuka chave chichizivikanwa kuti chinorapwa nesodium triphosphate, ichibatira chinangwa chakafanana sezvachinoita mukudya kwevanhu.
Application
1. Sodium tripolyphosphate inoshandiswa pakugadzira nyama, synthetic detergent formulations, textile dyeing, inoshandiswawo seanoparadzira agent, solvent etc.
2. Inoshandiswa semvura yakapfava, inoshandiswawo muindasitiri yezviyo.
3. Inoshandiswa sezviteshi zvemagetsi, locomotive mota, boiler uye fetereza chirimwa chinotonhorera kurapwa kwemvura, mvura inopfavisa. Iine simba rakasimba kuCa2 + collaterals, pa 100g kusvika kune yakaoma 19.5g calcium, uye nokuti SHMP chelation uye adsorption dispersion yakaparadza nzira yakajairika ye calcium phosphate crystal kukura, inodzivirira kuumbwa kwe calcium phosphate scale. Dosage ndeye 0.5 mg/L, kudzivirira kuti chiyero chechiyero chinosvika 95% ~ 100%.
4. Modifier; emulsifier; buffer; chelating agent; stabilizer. Kunyanya kune makedheni ham tenderization; bhinzi yakakura yemumagaba muYuba inopfava. Inogona zvakare kushandiswa semvura yakapfava, pH regulator uye thickening agent.
5. Inoshandiswa synergist ye sipo uye kudzivirira sipo girisi kunaya uye kutumbuka. Iine emulsification yakasimba ye
mafuta ekuzora nemafuta. Inogona kushandiswa kugadzirisa kukosha kwepH yebuffer fluid sipo. Industrial water softener. Pre
tanning agent. Kudhaya ebetsero. Paint, kaolin, magnesium oxide, calcium carbonate, senge maindasitiri mukugadzirira kwekumisikidzwa kweanoparadzira. Kuboora dhaka rinoparadzira. Muindasitiri yemapepa inoshandiswa se anti oiri agents.
6. Sodium tripolyphosphate inoshandiswa kune detergents. Sezvinowedzerwa, synergist ye sipo uye kudzivirira bha sipo crystallization uye maruva, maindasitiri mvura yakapfava, pre tanning agent, dyeing aibatsira, zvakanaka kuchera madhaka agent, bepa rine mafuta pakudzivirira agent, pendi, kaolin, magnesium oxide, calcium carbonate, yakadai. seyakarembera inoyangarara fluid kurapwa inoshanda
dispersant. Chikafu giredhi sodium tripolyphosphate seyakasiyana zvigadzirwa zvenyama, inovandudza chikafu, kujekeswa kwezvinwiwa zvinowedzera.
7. Hunhu hunovandudza kuvandudza chikafu chakaomeswa simbi ions, pH kukosha, kuwedzera ionic simba, nekudaro kuvandudza kutarisa kwekudya uye kugona kwemvura. Kupihwa kweChina kunogona kushandiswa kune zvigadzirwa zvemukaka, zvigadzirwa zvehove, zvigadzirwa zvehuku, ice cream uye instant noodles, yakanyanya dose ndeye 5.0g/kg; mumagaba, yakanyanya kushandisa muto (kuravira) zvinwiwa uye muriwo mapuroteni chinwiwa iri 1.0g/kg.
