Nrog rau kev paub txog kev tiv thaiv ib puag ncig, kev xaiv thiab kev siv cov khoom siv hauv txhua qhov chaw ntawm lub neej kuj tau them nyiaj ntau dua rau lawv cov phooj ywg ib puag ncig. Hauv kev tsim kho, tsheb, tsev, thiab lwm yam, tshuab tshuab ua cov khoom siv tseem ceeb, nws qhov kev ua tau zoo ib puag ncig tau nyiam ntau yam. Ammonia-dawb tshuab tshuab, raws li kev hloov pauv rau cov tshuaj ammonia-muaj tshuab tshuab, maj mam dhau los ua tus nyiam tshiab ntawm kev ua lag luam nrog nws qhov tshwj xeeb zoo. Tom ntej no, kuv yuav qhia peb tus neeg sawv cev tsis muaj ammonia kom ntxaws thiab sib tham txog nws daim ntawv thov hauv ntau qhov chaw.
· Ua lag luam keeb kwm ·
01Tam sim no foaming tus neeg saib xyuas kev ua lag luam nthuav dav
Nrog rau kev loj hlob ntawm kev lag luam downstream, qhov kev thov rau PVC tshuab tshuab yog tsis tu ncua. Muaj ntau hom PVC tshuab tshuab, thiab tib hom tshuab tshuab muaj cov yam ntxwv sib txawv thiab tsim nyog rau kev ua haujlwm tshwj xeeb thiab cov ntawv thov zaum kawg.
02Cov kev txwv ntawm cov tshuaj tshuab tshuab tsoos
Qee cov tshuaj tshuab tshuab ib txwm siv, xws li teeb meem ammonia, ua rau muaj kev hem thawj rau kev noj qab haus huv ntawm tus neeg teb xov tooj, thiab tseem tuaj yeem ua rau muaj kuab paug ib puag ncig thiab lwm yam teeb meem. Qee cov tshuab tshuab muaj halogens, uas tso cov tshuaj lom thaum hlawv thiab tsis ua raws li cov qauv niaj hnub no.
03Kev Ua Lag Luam
Kev lag luam xav tau rau cov ntaub ntawv ntsuab loj hlob tuaj, thiab nrog kev nce qib ntawm cov thev naus laus zis, cov neeg ua haujlwm zoo tshaj plaws thiab ib puag ncig PVC tshuab tshuab tau tshwm sim hauv khw. Tsis tas li ntawd, txhawm rau ua kom tau raws li cov qauv nruj dua ib puag ncig, kev lag luam tau txav mus los ntawm cov khoom lag luam.
04Txoj cai thiab kev coj noj coj ua
Tsoom fwv txoj cai tiv thaiv ib puag ncig nruj zuj zus tau ua rau kev lag luam hloov mus rau ntau tus phooj ywg ib puag ncig tshuab tshuab. Piv txwv li, qee lub teb chaws thiab cheeb tsam tau pib txwv lossis txwv tsis pub siv qee yam tshuaj tua kab mob uas ua rau muaj kev phom sij rau ib puag ncig, thaum txhawb kev siv cov ntaub ntawv tshiab uas zoo rau ib puag ncig.
· Txheej txheem cej luam ntawm ammonia-dawb tshuab tshuab ·
Ammonia free blowing agent yog hais txog lub tshuab tshuab uas tsis tsim cov ammonia lossis muaj cov ammonia tso tawm tsawg heev thaum lub sijhawm ua npuas dej. Piv nrog rau cov tshuaj ammonia ib txwm muaj cov tshuaj tua kab mob, cov tshuaj ammonia dawb tshuab tsis muaj tshuaj lom, tsis tshua muaj ntxhiab tsw thiab ua haujlwm zoo ib puag ncig. Nws yog tsim los ntawm tshuaj lom neeg cov tshuaj tiv thaiv ntawm polyol, isocyanate thiab lwm yam ntaub ntawv raw, thiab muaj zoo heev foaming zog thiab stability.
01Kev tiv thaiv ib puag ncig ntsuab, tsis muaj ammonia roj
02Tsis muaj teeb meem rau tib neeg lub cev, tsis muaj pungent tsw
03Ua raws li kev cai ib puag ncig, yooj yim rau export
