Hauv qab no yog cov cim tseem ceeb ntawm cov hmoov tshuaj tua hluav taws cov tshuaj tua hluav taws:
1.Cov khoom siv pleev roj.
Dej tshuaj tawm yog qhov taw qhia tseem ceeb. Cov dej pleev cov tshuaj ntawm ammonium phosphate qhuav cov hmoov tua hluav taws cov tshuaj tua kab mob, hu ua ABC qhuav tshuaj lom hmoov feem ntau cuam tshuam rau cov teeb meem, thiab muaj ntau yam. Lub ammonium ntsev ntsev yog ntsev dhau lawm tsoo. Txawm hais tias qhov tua hluav taws muaj peev xwm hloov tau zoo heev, qhov dej hloov kho dej tau raug txo qis. Raws li cov seem loj txo, qhov tshwj xeeb roj qhov chaw tau nce ntau, thiab ntau cov roj silicone yog xav tau kom tau raws li cov nplaim teeb meem saum npoo ntawm ultrafine hais. Txawm li cas los xij, qhov ntau ntawm cov roj silicone tsis tuaj yeem txaus siab qhov kev ua kom nto ntawm kev lees paub ultrafine, yog li cov dej pleev kom tsawg. Tsis tas li ntawd, thaum lub particle loj dhau zoo, tsawg dua los yog ze rau qhov loj ntawm hydrophobic dawb carbon dub, nws yuav ua rau ammonium phosphate mus rau adsorb puag ncig lub hydrophobic dawb carbon dub hais, thiab yuav tsis ua si hydrophobic muaj nuj nqi (4) Cov. Raws li lub ntsiab dej pleev cov tshuaj Dej Hydrophobic dawb carbon xim dub, thov xyuam xim xyuas nws cov nyhuv hydrophobic, kuaj nws qhov zoo, thiab qhov nyiaj ntxiv yuav tsum tsim nyog, qhov loj me yuav tsum zoo, txwv tsis pub nws nyuaj rau adsorb ncig ntawm hmoov; tab sis cov particle loj yuav tsum tsis txhob dhau zoo, txwv tsis pub nws qhov kev ua tau zoo hydrophobic tsis zoo. Silicone roj yuav tsum tau ntxiv rau hauv cov nyiaj txaus. Tus nqi thiab kev faib tawm ntawm dej thiab catalyst thiab qhov kub yuav cuam tshuam rau polymerization thiab solidification ntawm silicone roj, uas nyob rau hauv lem yuav cuam tshuam dej repellency. Tom qab ntxiv cov pa roj carbon dawb dub, cua ceev ntawm qhov chaw nres nkoj dehumidifying yuav tsum tsis txhob loj dhau, txwv tsis pub ib feem ntawm cov pa roj carbon dawb hydrophobic yuav ploj thiab cov dej tsis huv yuav cuam tshuam. Tsis tas li ntawd, cov hmoov txheej tawm ntawm cov khoom siv sib xyaw yuav tsum muab sib khi los tiv thaiv tus neeg sawv cev ntawm cov khoom ua kom tiav ua ntej cov siliconization tiav, thiab thaum kawg nkag mus rau cov khoom tiav, uas ib feem cuam tshuam rau cov dej repellency ntawm cov khoom tiav.
2 Muaj dej noo haum kev haum
Qhov kev nqus dej noo ntawm ammonium phosphate qhuav hmoov tshuaj tua hluav taws tua hluav taws yog qhov ntsuas tseem ceeb heev rau ABC tshuaj hmoov, thiab nqus dej noo yog qhov ua kom ncaj ntawm cov hmoov qhuav agglomeration. Kev nqus noo ntau dhau yuav ua rau cov hmoov qhuav kom khov thaum lub sijhawm khaws cia thiab cuam tshuam rau kev siv. Cov dej noo nqus cov yam ntxwv ntawm ammonium phosphate qhuav hmoov tua hluav taws tso tawm tus neeg sawv cev tsuas yog txiav txim siab los ntawm hygroscopicity ntawm ammonium dihydrogen phosphate. Cov kev sim qhia tau qhia tias ammonium dihydrogen phosphate tuaj yeem ua rau phosphoric acid thiab ammonia ntawm chav tsev kub: NH4H2PO4-NH3 + H3PO4. Phosphoric acid yog qhov sib xyaw hygroscopic heev. Vim hais tias phosphoric acid npog cov npoo ntawm ammonium dihydrogen phosphate thiab txuas ntxiv nqus cov dej noo los ntawm cov huab cua, ua rau muaj kev nce nqi ntawm ammonium dihydrogen phosphate. Yog li no, yog tias phosphoric acid tuaj yeem ua nrog lwm cov tshuaj hauv lub sijhawm, Txo thiab tshem tawm phosphoric acid yuav cuam tshuam qhov kev nqus ntawm ammonium dihydrogen phosphate. Piv txwv, calcium phosphate yog siv los kho nrog phosphoric acid. Tsis tas li ntawd, cov dej noo nqus dej ntawm ammonium dihydrogen phosphate kuj tseem cuam tshuam los ntawm qhov loj me ntawm qhov me me thiab lub sijhawm khaws. Ua kom zoo li cov qhov me me qhov loj me, lub sijhawm khaws cia ntev dua thiab ntau cov phosphoric acid decomposed, ntau dua cov dej noo noo ntau npaum li cas. Nyob rau tib lub sijhawm, cov av noo ntawm qhov chaw sab nraud muaj qhov cuam tshuam zoo heev ntawm kev nqus noo noo ntawm ammonium dihydrogen phosphate. Raws li cov av noo nce, qhov kev nqus noo noo nce nrawm nrawm (5). Raws li tau pom los ntawm kev txheeb xyuas saum toj no, nws yuav tsum tau nrhiav txo qis ntawm ammonium phosphate qhuav hmoov tua hluav taws cov tshuaj tua kab mob rau cov chaw muaj huab cua sov siab, tshwj xeeb tshaj yog cov uas muaj tus txheeb ze cov av noo ntau dua 60%, uas tau txais txiaj ntsig los txo cov dej noo noo tus nqi ntawm cov tshuaj tua hluav taws. Tsis tas li ntawd, ib qho me me ntawm diammonium phosphate nyob rau hauv ammonium dihydrogen phosphate yog qhov yuav ua rau muaj ntau lub hygroscopicity ntawm cov tshuaj tua hluav taws vim nws cov dej noo siab npaum li cas. Cov hom, qhov zoo, ntau npaum li cas ntawm cov roj silicone, qhov kub thiab qhov kawg ntawm cov hmoov qhuav thaum ua polymerization yuav cuam tshuam rau tus nqi noo noo kom txaus siab. Qee qhov ua kom tsis muaj zog nyob hauv cov khoom sib tov, cov raj xa dej thiab lwm lub tshuab, xws li sodium bicarbonate, nkag rau hauv qhov system thiab nkag mus rau hauv kev sib cuag nrog ammonium dihydrogen phosphate los ua cov tshuaj tiv thaiv tshuaj, tsim cov tshuaj nrog qhov siab nqus dej noo, uas cuam tshuam rau cov khoom lag luam noo noo npaum li cas.
