Kiimikada Pengfa - taxaddarrada marka la isticmaalayo phosphoric acid

      Fosfooraska acidwaa aashitada inorganic ee caadiga ah oo leh qaacidada kiimikada H3PO4.Ma fududa in la rogmado, ma fududa in la dumiyo, si fududna in hawada loo maro.Fosfooraska acid waa asiidh dhexdhexaad ah oo xoog leh oo leh bar crystallization 21 ° C.Marka heerkulku ka hooseeyo heerkulkan, kiristaalo hemihydrate ayaa soo da'i doona.Kuleylku wuxuu lumin doonaa biyaha si uu u helo pyrophosphoric acid, ka dibna wuxuu lumin doonaa biyo si loo helo metaphosphoric acid.Fosfooraska waxay leedahay hantida aashitada, aysiidhkeedu wuu ka daciifsan yahay hydrochloric acid, sulfuric acid, nitric acid, laakiin ka xoog badan acetic acid, boric acid, iwm.

isticmaal:

Daawo: Phosphoric acid waxaa loo isticmaali karaa in lagu diyaariyo daawooyinka fosfooraska ku jira, sida sodium glycerophosphate.Beeraha: Phosphoric acid waa walxo ceeriin ah oo muhiim u ah soo saarista bacriminta fosfatetada (superphosphate, potassium dihydrogen phosphate, iwm.), iyo sidoo kale soosaarka nafaqooyinka quudinta (calcium dihydrogen phosphate);

Cuntada: Phosphoric acid waa mid ka mid ah cuntooyinka lagu daro.Waxa loo isticmaalaa sida wakiilka dhanaan iyo nafaqada khamiirka ee cuntada.Coca-cola waxa ku jira phosphoric acid.Phosphate sidoo kale waa cunto lagu daro muhiim ah waxaana loo isticmaali karaa kobciye nafaqo;

Warshadaha: Phosphoric acid waa walxo kiimiko ah oo ceeriin ah oo muhiim ah, shaqadeeda ugu weynna waa sidan;

1. Ku daawee dusha birta si aad u sameysid filim fosfooreed aan la milmi karin oo ku yaal dusha birta si aad uga ilaaliso birta daxalka;

2. Lagu qaso nitric acid sida kiimikaad dhalaalaysa si loo hagaajiyo jilicsanaanta dusha birta;

3. Fosfate esters, alaabta ceeriin ee wax soo saarka saabuunta iyo sunta cayayaanka;

4. Qalabka ceeriin ee soo saarista fosfooraska-ka kooban ololka;

Taxadirrada marka la isticmaalayo phosphoric acid:

Si maqaarka looga ilaaliyo fosfooraska, waxaan kugula talineynaa inaad xirato dharka difaaca kiimikada sida kabaha, dharka ilaalinta iyo galoofyada, waxaan sidoo kale kugula talineynaa inaad iibsato harag ka samaysan caag dabiici ah, polyvinyl chloride, caag nitrile ah, caag butyl ama qalabka difaaca neoprene.

Si looga ilaaliyo wejiga ama indhaha walxaha xajiimka iyo daxalka leh, waxaan kugula talineynaa isticmaalka muraayadaha badbaadada ilaalinta kiimikada.

Marka lagu daro hawo-qaadista guud ee hawada, waxaanu kugula talineynaa isticmaalka hawo-qaadista qiiqa maxaliga ah si looga hortago khatarta neefsashada marka la isticmaalayo fosfooraska, dhammaan taxadarka deegaanka ee lagama maarmaanka ah waa in la qaadaa, qiiqa waxaa laga yaabaa in loo baahdo in si toos ah dibadda looga soo saaro.
