polyphosphoric acidDaim ntawv thov:
Polyphosphoric acid (PPA) yog lub cev qhuav dej, tsis tshua muaj nucleophile thiab acidic. Tsis zoo li sulfonic acid, polyphosphate feem ntau tsis oxidize cov reactants thiab soluble hauv organic solvents. Txawm hais tias nws cov acidity tsis muaj zog dua li sulfonic acid, nws yog dehydrating li sulfonic acid, yog li nws tau dav siv hauv chav kuaj. Nws yog siv los ua compound cyclization tus neeg saib xyuas thiab acylation tus neeg sawv cev hauv cov organic synthesis. Nws kuj yog siv los ua ib qho kev hloov rau orthophosphoric acid thiab ib qho tshuaj analytical reagent.
Cov yam ntxwv txaus ntshai:
Cov tshuaj tiv thaiv nrog cov hlau tso tawm hydrogen, uas tuaj yeem tsim kev sib xyaw nrog huab cua. Decomposition los ntawm tshav kub ua rau muaj tshuaj lom phosphorus oxide flue gas. Nws yog corrosive. Kev phom sij rau kev noj qab haus huv: Lub ncu lossis pos huab ua rau lub qhov muag, qhov ntswg thiab caj pas. Cov kua hauv qhov ncauj tuaj yeem ua rau xeev siab, ntuav, mob plab, quav ntshav lossis xeev siab. Kev sib cuag ntawm daim tawv nqaij tuaj yeem ua rau kub hnyiab. Cov teebmeem ntev: qhov ntswg mucosa atrophy, qhov ntswg septum perforation. Kev sib cuag ntawm daim tawv nqaij ntev ntev tuaj yeem ua rau tawv nqaij khaus.
Kev ua haujlwm pov tseg thiab khaws cia:
Kev ceev faj txog kev ua haujlwm: kaw kev ua haujlwm, ua tib zoo saib xyuas qhov cua. Kev khiav hauj lwm raws li mechanized thiab automated li sai tau. Cov neeg ua haujlwm yuav tsum tau kawm tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm. Nws raug nquahu kom cov neeg ua haujlwm hnav lub npog ntsej muag lub ntsej muag lub ntsej muag roj (ib nrab daim npog ntsej muag), tshuaj tiv thaiv tsom iav kev nyab xeeb, kua qaub thiab alkali tiv thaiv cov khaub ncaws ua haujlwm, thiab cov hnab looj tes tiv thaiv acid (alkali). Tiv thaiv kom tsis txhob muaj pa tawm mus rau hauv qhov chaw ua haujlwm huab cua. Tsis txhob kov cov oxidants. Thaum tuav, lub teeb loading thiab unloading yuav tsum tau ua kom tsis txhob muaj kev puas tsuaj rau lub ntim thiab ntim. Nruab nrog cov khoom siv kho mob thaum muaj xwm ceev. Ib lub thawv khoob yuav muaj cov residue puas tsuaj. Thaum diluting los yog npaj cov tshuaj, yuav tsum tau saib xyuas kom maj mam ntxiv cov kua qaub rau hauv dej kom tsis txhob overheating thiab spatter.
Kev ceev faj txog kev thauj mus los:
Thaum lub sij hawm kev thauj mus los, lub tsheb thauj mus los yuav tsum tau nruab nrog ntau yam thiab ntau ntawm cov khoom siv tua hluav taws thiab cov khoom siv kho mob thaum muaj xwm ceev. Nyob rau lub caij ntuj sov, nws yog qhov zoo tshaj rau nkoj thaum sawv ntxov thiab yav tsaus ntuj. Lub trough (tank) lub tsheb siv hauv kev thauj mus los yuav tsum muaj cov saw hlau hauv av, thiab lub qhov muab faib tuaj yeem npaj rau hauv lub trough kom txo cov hluav taws xob zoo li qub los ntawm kev poob siab. Nws yog nruj me ntsis txwv tsis pub sib xyaw nrog oxidants thiab halogens. Thaum lub sij hawm kev thauj mus los, nws yuav tsum tau tiv thaiv los ntawm tshav ntuj raug, nag thiab kub. Nyob deb ntawm nplaim taws, qhov chaw kub thiab qhov kub thiab txias thaum lub sijhawm nres. Cov kav dej ntawm cov tsheb nqa cov khoom yuav tsum tau nruab nrog cov khoom siv hluav taws xob. Kev thauj khoom thiab tshem tawm nrog cov cuab yeej siv tshuab thiab cov cuab yeej uas yooj yim los tsim cov txim hluav taws xob raug txwv. Txoj kev thauj mus los yuav tsum ua raws li txoj hauv kev, tsis txhob nyob hauv thaj chaw muaj neeg nyob thiab muaj neeg nyob. Nws yog txwv tsis pub plam lawv nyob rau hauv railway tsheb thauj mus los. Cov nkoj ntoo thiab cov cement ships raug txwv nruj rau kev thauj mus los ntau.
