Xauv Qhov Tsis Txaus Siab Ntawm Naphthalene Series Retarding Admixtures

Nyob rau hauv lub niaj hnub ua hauj lwm ntawm kev tsim kho, nrhiav kom tau ntau npaum li cas thiab high-kev ua tau zoo cov ntaub ntawv tau coj mus rau lub tseem ceeb nrhav nyob rau hauv lub pob zeb admixtures. Ntawm cov no, naphthalene-raws li admixtures sawv tawm vim lawv cov kev ua haujlwm dual: lawv tsis tsuas yog txo cov ntsiab lus dej thiab txhim kho lub zog tab sis kuj muaj qhov tshwj xeeb retarding nyhuv. Qhov no ua rau lawv tshwj xeeb tshaj yog tsim rau cov haujlwm tsim kho uas xav tau kev tswj xyuas meej ntawm lub sijhawm ua vaj tse.

Naphthalene system air-entraining admixtures sawv cev rau lwm pawg tshwj xeeb. Cov khoom sib xyaw no tsis yog tsuas yog txo qis kev siv dej thiab txhawb zog tab sis kuj suav nrog huab cua rau hauv cov pob zeb. Qhov kev taw qhia ntawm huab cua no txhim kho qhov ua tau zoo ntawm cov pob zeb, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas raug rau lub voj voog khov-thaw, thiab pab txhawb kev txhim kho kev ua haujlwm thiab ua kom tiav.

Tam sim no, naphthalene-raws li admixtures dominate lub khw, accounting rau ib feem tseem ceeb ntawm tag nrho cov admixture muag. Qhov kev nthuav dav no yog vim lawv qhov kev ua tau zoo thiab qhov nyuaj ntawm kev tsim vaj tsev uas xav tau ntau yam khoom siv hauv tsev.

Raws li kev tsim kho thev naus laus zis tau nce zuj zus thiab qhov nyuaj ntawm kev tsim vaj tsev nce, cov kev xav tau ntawm cov pob zeb ua haujlwm loj hlob raws li. Qhov no tau ua rau muaj kev nce siab hauv ntau yam thiab kev ua kom zoo ntawm cov khoom sib xyaw muaj. Cov neeg tsim khoom thiab cov chaw tsim khoom tau tsim kho tshiab tas li los tsim cov khoom sib xyaw uas ua tau raws li ntau yam kev xav tau tshwj xeeb, los ntawm kev txhim kho lub twj tso kua mis thiab txuas ntxiv ua haujlwm kom txo tau qhov cuam tshuam ib puag ncig.

Cov toj roob hauv pes yav tom ntej ntawm kev sib xyaw ua vaj tse yuav tsum tau hloov mus rau ntau qhov kev qhia. Tej zaum yuav muaj ntau qhov sib txawv ntawm cov khoom siv ntxiv vim tias cov qauv tshiab tau tsim los daws cov teeb meem tshwj xeeb engineering. Qhov kev thov rau cov khoom siv ua haujlwm siab tau npaj siab yuav nce siab, qhia txog kev lag luam thawb mus rau cov khoom siv ruaj khov, ruaj khov, thiab cov nqi tsim nyog. Raws li qhov tshwm sim, kev ua lag luam rau cov khoom sib xyaw ua ke yog npaj rau kev nthuav dav, nrog cov khoom siv tshiab, zoo dua qub uas tswj hwm tus nqi hwm.

Hauv kev xaus, naphthalene-raws li admixtures yog qhov tseem ceeb hauv kev hloov pauv ntawm kev siv pob zeb, ua tau raws li cov kev xav tau tam sim no thiab cov kev xav tau yav tom ntej. Raws li kev tsim kho kev lag luam txuas ntxiv tsim kho tshiab, cov khoom sib xyaw no yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov chaw tsim khoom.
