Thaum xaiv cov khoom siv sib tov rau cov hmoov, cov hmoov me me, thiab cov khoom siv slurries, cov khoom sib tov kab rov tav thiab cov khoom sib tov ntsug yog ob qho kev xaiv feem ntau. Ntau tus neeg siv nug: qhov twg zoo dua? Cov lus teb yog tias tsis muaj qhov "zoo dua" lossis "phem dua" - nws tsuas yog nyob ntawm qhov tsim nyog.
I. Kev Sib Piv ntawm Cov Qauv thiab Cov Ntsiab Cai Ua Haujlwm
Lub tshuab sib tov kab rov tav muaj lub thawv U-zoo li tus qauv uas siv qhov chaw loj heev rau sab nraud. Nws lub tshuab sib tov muaj ob txheej (sab hauv thiab sab nraud) lossis ib txheej ribbons uas ntsia rau ntawm lub qhov tseem ceeb kab rov tav. Thaum cov ribbons tig, lawv thawb cov khoom los ntawm qhov kawg mus rau hauv nruab nrab (lossis rov qab), tsim kom muaj kev sib xyaw ua ke ntawm convective thiab shearing. Cov khoom siv hla kev ncig dynamic - tumbling vertically thiab ntws axially - ua rau muaj kev sib tov hnyav. Cov khoom sib tov no muaj qhov tso tawm tag nrho ntawm qhov hauv qab uas muaj lub valve pneumatic lossis manual; cov khoom tawm ntawm lub ntiajteb txawj nqus, pab los ntawm cov ribbons tig thawb nws mus rau qhov tawm, kom ntseeg tau tias kev tawm sai thiab du.
Qhov sib txawv, lub tshuab sib tov ntsug muaj lub thawv cylindrical uas nyob ntsug; txawm hais tias nws muaj qhov chaw me me, nws xav tau qhov siab dua ntawm lub qab nthab. Nws lub tshuab sib tov feem ntau muaj cov hniav tsa ib txheej lossis ob txheej uas tau teeb tsa rau ntawm lub ncej tseem ceeb ntsug. Thaum cov hniav tig, lawv nqa cov khoom los ntawm hauv qab mus rau sab saud, qhov twg nws ntws mus rau sab nraud thiab nqis los, tsim kom muaj cov qauv ncig ntsug convective feem ntau nrog kev sib tov maj mam. Lub qhov hluav taws xob tawm yog nyob rau hauv qab lossis sab qis dua, nrog rau cov khoom feem ntau tawm los ntawm lub ntiajteb txawj nqus.
II. Qhov sib txawv ntawm Cov Khoom Siv thiab Cov Kev Siv Uas Tsim Nyog
Cov khoom sib tov kab rov tav muaj kev hloov pauv ntau yam khoom siv, ua tau zoo tswj txhua yam los ntawm cov hmoov thiab cov granules uas ntws dawb mus rau cov khoom siv uas tsis ntws zoo lossis nyiam sib sau ua ke. Lawv kuj tseem tuaj yeem nruab nrog cov tshuab txau kua rau kev sib tov kua-khoom, ua rau lawv haum rau cov txheej txheem uas xav tau ntxiv cov binders, roj, pigments, lossis lwm yam khoom siv kua; lawv siv dav hauv kev lag luam xws li zaub mov, tshuaj, tshuaj lom neeg, pub tsiaj, thiab cov ntaub ntawv tsim kho.
Piv txwv li, cov tshuab sib tov ntsug feem ntau yog tsim rau cov hmoov thiab cov hmoov me me thiab xav kom cov khoom siv muaj qee qib ntawm kev ntws. Thaum tuav cov khoom sib xyaw nrog qhov sib txawv tseem ceeb hauv qhov hnyav tshwj xeeb, cov tshuab sib tov ntsug feem ntau yuav raug faib ua pawg thaum lub sijhawm sib tov. Kev hloov kho cov tshuab sib tov ntsug kom muaj cov kua ntxiv yog qhov nyuaj; cov kua txau feem ntau ua rau muaj kev sib sau ua ke, ua rau nws nyuaj rau kom ntseeg tau tias sib tov sib xws.
III. Kev Sib Piv ntawm Kev Ntxuav thiab Kev Txij Nkawm
Yuav kom ua tau raws li cov qauv kev huv huv ntawm cov lag luam zaub mov thiab tshuaj, cov tshuab sib tov kab rov tav tuaj yeem nruab nrog Clean-in-Place (CIP) systems, txo qhov kev ua haujlwm ntxuav tes. Kev saib xyuas feem ntau tsom mus rau cov foob ntawm lub qhov, qhov twg cov khoom seem yuav sib sau ua ke, uas yuav tsum tau kuaj xyuas thiab hloov foob tsis tu ncua.
Nws raug pom zoo kom piav qhia meej txog koj cov yam ntxwv ntawm cov khoom siv, cov txheej txheem xav tau, thiab cov qauv kev huv ua ntej xaiv cov khoom siv kom ntseeg tau tias qhov kev xaiv zoo tshaj plaws.
