Hauv phosphorus-raws li kev siv tshuaj lom neeg, phosphites, nrog rau lawv cov qauv tshuaj lom neeg thiab cov khoom sib txawv, tau dhau los ua cov khoom siv tseem ceeb hauv ntau qhov kev lag luam. Lawv cov txiaj ntsig tsis yog nyob rau hauv kev ncaj qha daws teeb meem tseem ceeb hauv cov txheej txheem tsim khoom, tab sis kuj tseem txhawb cov txheej txheem optimization, txhim kho cov khoom ua tau zoo, thiab ua kom muaj kev ruaj ntseg ib puag ncig. Yog li ntawd, lawv muaj cov txiaj ntsig tseem ceeb hauv kev tsim tshuaj lom neeg niaj hnub thiab cov ntawv thov cuam tshuam.
Tus nqi tseem ceeb ntawm phosphites feem ntau yog los ntawm lawv cov kev ua haujlwm tshuaj lom neeg. Cov P–H thiab P=O ob daim ntawv cog lus nyob rau hauv lub molecule ua tau raws li qhov sib npaug ntawm kev txo hwj chim thiab kev sib koom tes muaj peev xwm, tso cai rau cov hom phiaj xaiv raws li cov xwm txheej sib txawv. In the fields of metal surface treatment and electroplating, phosphites can efficiently reduce metal ions, promote the formation of uniform and dense coatings, significantly improve the corrosion resistance and surface finish of products, while inhibiting side reactions, extending the service life of working solutions, thereby reducing production costs and improving process stability.
Hauv kev lag luam ntawm cov ntaub ntawv tshawb fawb thiab engineering, cov tshuaj tiv thaiv antioxidant thiab thermal stabilizing los ntawm phosphites muab rau lawv nrog tus nqi tseem ceeb. Polyvinyl chloride (PVC), polyester, thiab engineering plastics raug cuam tshuam rau degradation nyob rau hauv thermo- oxidative kev nyuaj siab thaum ua thiab kev pab cuam. Ntxiv cov phosphites uas tsim nyog tuaj yeem ntes cov dawb radicals sai, thaiv cov oxidative chain reactions, ncua cov khoom laus, thiab tswj cov khoom siv thiab zoo nkauj. Qee cov phosphite derivatives, vim lawv qhov tsis muaj zog thiab ib puag ncig sib raug zoo, tuaj yeem hloov cov yas yas los yog ua raws li cov nplaim hluav taws xob sib xyaw ua ke, ua raws li cov qauv ntawm kev tsim ntsuab thiab kev nyab xeeb, thiab muab txoj hauv kev ua tau zoo rau siab - kev ua tau zoo thiab kev txhim kho ruaj khov ntawm cov ntaub ntawv polymer.
Phosphites kuj qhia tau tias muaj txiaj ntsig zoo hauv kev tiv thaiv ib puag ncig thiab kev siv peev txheej. Hauv kev kho dej thiab kev tiv thaiv corrosion engineering, lawv tuaj yeem tsim cov adsorption lossis passivation films ntawm cov hlau nto, zoo inhibiting electrochemical corrosion thiab scaling, txo cov khoom siv tu zaus thiab kev siv zog siv, thiab ua kom lub sijhawm ntev -kev ruaj khov ntawm cov tshuab xws li kev lag luam circulating water, boiler water supply, thiab oilfield water injection. Hauv kev ua liaj ua teb thiab kev txhim kho ecological, qis - phosphites toxicity tuaj yeem ua cov tshuaj tiv thaiv kab mob los yog cov kab mob cab, txhawb kev noj qab haus huv qoob loo thiab txo cov kab mob. Lawv kuj ua lub luag haujlwm hauv kev kho cov tshuaj chlorine seem thiab qee cov oxidizing cov pa phem hauv cov dej, nthuav lawv cov eco-cov ntaub ntawv siv tau zoo.
Hauv kev npaj siab - tshuaj lom neeg kawg thiab cov khoom siv ua haujlwm, phosphites, ua cov khoom siv sib xyaw ua ke, tuaj yeem siv los ua cov nplaim hluav taws xob, cov khoom siv roj nplua nyeem, thiab cov khoom siv hlau ua kom yooj yim. Lawv cov reactivity tswj tau thiab kev sib koom tes muaj peev xwm txhim kho cov kev ua tau zoo thiab cov khoom xaiv ntawm cov txheej txheem hluavtaws, muab kev txhawb nqa rau kev tsim lub zog tshiab, cov ntaub ntawv hluav taws xob, thiab cov ntaub ntawv biomedical.
Hauv cov ntsiab lus, tus nqi ntawm phosphites nyob rau hauv peb yam: hla-kev ua haujlwm tau zoo, kev ua kom zoo dua qub, thiab kev txhim kho ntsuab. Nrog nws ntau yam tshuaj ua haujlwm, cov txheej txheem yoog raws, thiab ib puag ncig tus phooj ywg, nws muab cov tswv yim daws teeb meem rau kev ua hlau, kev hloov pauv polymer, kev tswj hwm ib puag ncig, kev txhim kho kev ua liaj ua teb, thiab kev tsim tshuaj tshwj xeeb. Nws nyob rau hauv - kev txhim kho tob thiab cov ntawv thov sib xyaw yuav ua lub luag haujlwm tseem ceeb hauv kev txhawb kev hloov pauv kev lag luam thiab kev txhim kho thiab ua tiav cov hom phiaj kev txhim kho kom ruaj khov.
