Daim ntawv thov nyob rau hauv yas additives
3,5-dinitrosalicylic acid(abbreviated li: DNS), Nws yog ib qho tseem ceeb organic compound. Hauv kev lag luam yas, DNS lossis nws cov derivatives tuaj yeem siv los ua cov khoom siv yas los txhim kho kev ua haujlwm ntawm cov ntaub ntawv yas. Cov nram qab no yog nws siv nyob rau hauv yas additives:
DNS molecules muaj cov pab pawg ua haujlwm xws li hydroxyl (- OH), nitro (- NO2), thiab carboxyl (- COOH). Cov pab pawg ua haujlwm no tso cai rau DNS nrog cov khoom siv tshuaj lom neeg tshwj xeeb, ua rau nws cuam tshuam nrog qee yam hauv cov ntaub ntawv yas thiab txhim kho lawv cov kev ua tau zoo. DNS lossis nws cov derivatives tuaj yeem muab ntxiv los ua cov khoom siv ntxiv rau cov ntaub ntawv yas. Lawv tuaj yeem tsim cov ntawv cog lus hydrogen lossis ionic bonds nrog cov yas molecular chains los txhim kho lub zog ntawm cov khoom yas, yog li txhim kho lawv cov khoom siv xws li hardness, hnav tsis kam, thiab tensile zog. Nyob rau hauv cov txheej txheem ntawm kev sib xyaw ntawm cov yas los yog cov khoom sib xyaw, qhov sib xyaw ua ke ntawm cov khoom sib txawv ntawm cov yas sib txawv feem ntau tsis zoo, ua rau qhov kev ua tau zoo ntawm cov khoom sib xyaw lossis cov khoom sib xyaw.
DNS los yog nws cov derivatives tuaj yeem muab ntxiv ua cov khoom sib xyaw ua ke rau cov khoom siv yas los yog cov khoom sib xyaw, txhawb kev sib cuam tshuam ntawm cov khoom yas sib txawv los ntawm lawv cov qauv tshuaj tshwj xeeb, thiab txhim kho kev sib raug zoo thiab kev ua haujlwm ntawm cov khoom sib xyaw lossis cov khoom sib xyaw. DNS lossis nws cov derivatives tuaj yeem txhim kho kev ua haujlwm ntawm cov ntaub ntawv yas. Piv txwv li, lawv tuaj yeem txo cov viscosity yaj ntawm cov yas, txhim kho lawv cov flowability thiab formability, ua rau cov ntaub ntawv yas yooj yim rau kev tsim thiab txheej txheem thaum ua.
Daim ntawv thov tshwj xeeb hauv cov khoom siv yas
DNS los yog nws cov derivatives tuaj yeem muab ntxiv los ua cov tshuaj ntxiv rau cov ntaub ntawv yas xws li polycarbonate, polyamide, polyester, thiab lwm yam. Piv txwv li, ntxiv tus nqi tsim nyog ntawm DNS lossis nws cov derivatives rau polycarbonate tuaj yeem txhim kho nws cov tawv tawv thiab hnav tsis kam, ua rau nws tsim nyog rau kev tsim cov khoom lag luam yas siab. DNS los yog nws cov derivatives tuaj yeem siv los ua cov sib xyaw ua ke hauv cov txheej txheem kev npaj ntawm cov yas sib xyaw lossis cov khoom sib xyaw. Piv txwv li, hauv cov txheej txheem sib xyaw ntawm polyolefin thiab polystyrene, ntxiv qhov tsim nyog ntawm DNS lossis nws cov derivatives tuaj yeem txhim kho kev sib raug zoo thiab cov khoom ntawm kev sib xyaw.
Tsis tas li ntawd, DNS los yog nws cov derivatives kuj tuaj yeem siv los ua cov neeg sawv cev txhawb nqa hauv kev npaj cov khoom siv yas sib xyaw los txhim kho lawv cov khoom siv kho tshuab thiab kav ntev. DNS lossis nws cov derivatives kuj tuaj yeem siv los npaj cov yas tshwj xeeb. Piv txwv li, thaum npaj cov yas tshwj xeeb uas tiv taus qhov kub thiab txias, qhov tsim nyog ntawm DNS lossis nws cov derivatives tuaj yeem muab ntxiv los txhim kho qhov kub thiab txias thiab hnav tsis kam ntawm cov yas. Tsis tas li ntawd, thaum npaj cov yas tshwj xeeb nrog cov haujlwm tshwj xeeb (xws li nplaim hluav taws- cov yas retardant, cov khoom siv hluav taws xob, thiab lwm yam), 3DNS lossis nws cov derivatives kuj raug suav tias yog cov khoom ntxiv.
Tom qab ntxiv DNS lossis nws cov derivatives, cov khoom siv kho tshuab xws li hardness, hnav tsis kam, thiab tensile lub zog ntawm cov ntaub ntawv yas tau zoo dua. Qhov no yog vim muaj kev sib cuam tshuam ntawm DNS los yog nws cov derivatives thiab cov yas molecular chains, uas txhim kho cov intermolecular rog ntawm cov ntaub ntawv yas. DNS los yog nws cov derivatives tuaj yeem txo cov yaj viscosity ntawm cov yas, txhim kho lawv cov flowability thiab formability. Qhov no ua rau cov ntaub ntawv yas yooj yim dua rau kev tsim thiab txheej txheem thaum lub sijhawm tsim khoom, txhim kho kev tsim khoom thiab cov khoom zoo.
Nyob rau hauv cov txheej txheem kev npaj ntawm cov yas blends los yog composites, kev siv DNS los yog nws cov derivatives raws li compatibilizers tuaj yeem txhim kho kev sib raug zoo thiab kev ua tau zoo ntawm cov khoom sib xyaw lossis cov khoom sib xyaw. Qhov no pab daws teeb meem kev sib raug zoo ntawm cov khoom siv yas sib txawv thiab txhim kho tag nrho cov kev ua tau zoo ntawm cov khoom sib xyaw lossis cov khoom sib xyaw. Los ntawm kev kho tus nqi thiab hom DNS lossis nws cov derivatives ntxiv, cov ntaub ntawv yas tuaj yeem tau txais txiaj ntsig nrog cov haujlwm tshwj xeeb. Piv txwv li, ntxiv DNS derivatives nrog nplaim retardant zog tuaj yeem txhim kho cov nplaim retardant ntawm cov yas; Ntxiv conductive3,5-dinitrosalicylic acidderivatives tuaj yeem npaj cov yas conductive, thiab lwm yam.
Kev ceev faj rau kev siv cov yas additives
Tus nqi ntawm DNS lossis nws cov derivatives ntxiv yuav tsum tau tswj nruj me ntsis. Ntxiv me ntsis yuav tsis ua tiav qhov kev xav tau; Kev sib ntxiv ntau dhau tuaj yeem ua rau txo qis hauv kev ua haujlwm lossis txawm tias tsis ua haujlwm ntawm cov ntaub ntawv yas. Yog li ntawd, kev sim txaus thiab kev sim yuav tsum tau ua ua ntej siv los txiav txim siab qhov zoo tshaj plaws. Kev ntsuas kev sib raug zoo yuav tsum tau ua ua ntej ntxiv DNS lossis nws cov khoom siv rau cov ntaub ntawv yas. Txhawm rau kom muaj kev sib raug zoo nrog cov ntaub ntawv yas thiab zam cov teeb meem xws li delamination thiab tawg. DNS lossis nws cov derivatives muaj qee yam cuam tshuam rau kev ua haujlwm ntawm cov ntaub ntawv yas, xws li kub, siab, ceev, thiab lwm yam.
Yog li ntawd, nws yog ib qho tsim nyog los txhim kho cov txheej txheem ua ntej siv los xyuas kom meej tias cov ntaub ntawv yas muaj kev ua tau zoo thiab cov khoom zoo. DNS los yog nws cov derivatives yuav muaj qee yam toxicity thiab irritability. Yog li ntawd, yuav tsum muaj kev ntsuam xyuas kev nyab xeeb ua ntej siv los xyuas kom meej tias nws tsis muaj teeb meem rau ib puag ncig thiab tib neeg kev noj qab haus huv. Nyob rau tib lub sijhawm, kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua thaum siv, xws li hnav tsom iav tiv thaiv, qhov ncauj qhov ntswg, hnab looj tes, thiab lwm yam khoom siv tiv thaiv tus kheej.
