Cov Kev Cai Huv Si rau Cov Saw Hlau Roller hauv Cov Tshuab Ua Khoom Noj

I. Cov Txheej Txheem Thoob Ntiaj Teb Tseem Ceeb rau Cov Hlua Hlua Huv Si

Cov kev cai huv rau cov saw hlau hauv cov tshuab ua zaub mov tsis yog cais tawm tab sis muab tso rau hauv lub kaw lus kev nyab xeeb zaub mov thoob ntiaj teb, feem ntau ua raws li peb pawg qauv:
* **Daim Ntawv Pov Thawj Khoom Siv Rau Khoom Noj:** FDA 21 CFR §177.2600 (Tebchaws USA), EU 10/2011 (EU), thiab NSF/ANSI 51 qhia meej tias cov khoom siv saw hlau yuav tsum tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab muaj qib kev tsiv teb tsaws chaw ntawm cov hlau hnyav ≤0.01mg/dm² (ua raws li kev sim ISO 6486);
* **Cov Qauv Tsim Kev Huv Huv Tshuab:** Daim ntawv pov thawj EHEDG Hom EL Class I xav kom cov khoom siv tsis muaj thaj chaw tsis huv, thaum EN 1672-2:2020 tswj hwm kev sib raug zoo ntawm kev huv thiab cov ntsiab cai tswj kev pheej hmoo rau cov tshuab ua zaub mov;
* **Cov Kev Cai Tshwj Xeeb Rau Kev Siv:** Piv txwv li, kev lag luam mis nyuj yuav tsum ua kom tau raws li qhov yuav tsum tau ua kom tsis txhob xeb hauv cov chaw uas muaj av noo thiab xeb ntau, thiab cov khoom siv ci yuav tsum tiv taus qhov kub thiab txias hloov pauv ntawm -30 ℃ txog 120 ℃.

II. Cov Qauv Kev Huv Si thiab Kev Nyab Xeeb rau Kev Xaiv Khoom Siv

1. Cov Khoom Siv Hlau: Kev Sib Npaug ntawm Kev Tiv Thaiv Kev Xeb thiab Kev Tsis Muaj Tshuaj Lom
Xaiv cov hlau tsis xeb 316L austenitic ua ntej, uas muaj kev tiv thaiv xeb zoo dua 30% dua li cov hlau tsis xeb 304 hauv cov chaw muaj chlorine (xws li kev ntxuav dej ntsev), tiv thaiv kev ua qias tuaj ntawm cov khoom noj uas ua rau muaj kev xeb ntawm cov hlau.
Tsis txhob siv cov hlau carbon lossis cov hlau sib xyaw uas tsis tau ntawv pov thawj, vim tias cov ntaub ntawv no yooj yim nqus cov hlau hnyav thiab tsis tiv taus cov tshuaj ntxuav acidic lossis alkaline uas siv rau hauv kev ua zaub mov (xws li 1-2% NaOH, 0.5-1% HNO₃).

2. Cov Cheebtsam Uas Tsis Yog Hlau: Kev Ua Raws Cai thiab Daim Ntawv Pov Thawj yog Qhov Tseem Ceeb
Cov menyuam, cov tes tsho, thiab lwm yam khoom siv tuaj yeem siv cov khoom siv UHMW-PE uas tau ntawv pov thawj los ntawm FDA, uas muaj qhov chaw du thiab ntom, tsis yooj yim lo rau qab zib, roj, lossis lwm yam khoom seem, thiab tiv taus kev ntxuav siab thiab kev xeb tshuaj tua kab mob.
Cov khoom yas yuav tsum ua tau raws li cov qauv khoom siv xiav lossis dawb tshwj xeeb rau kev lag luam zaub mov kom tsis txhob muaj kev pheej hmoo ntawm kev hloov pauv ntawm cov xim (piv txwv li, cov khoom yas ntawm igus TH3 series cov saw hlau huv).

III. Cov Ntsiab Cai ntawm Kev Tsim Qauv Kom Zoo Nkauj

Qhov sib txawv tseem ceeb ntawm cov saw hlau uas huv si thiab cov saw hlau lag luam ib txwm muaj yog lawv "tsis muaj lub kaum sab xis tuag," tshwj xeeb xav tau cov hauv qab no:

Cov Kev Cai ntawm Qhov Chaw thiab Ces kaum:
Kev kho kom zoo nkauj nrog daim iav ci ntsa iab Ra≤0.8μm kom txo cov kab mob me me;
Txhua lub ces kaum sab hauv ≥6.5mm, tshem tawm cov ces kaum ntse thiab qhov chaw nqaim. Ib qho kev tshawb fawb txog cov khoom siv ua nqaij qhia tau hais tias kev ua kom lub ces kaum sab hauv zoo dua ntawm 3mm mus rau 8mm txo qhov kev loj hlob ntawm cov kab mob los ntawm 72%;
Kev Tsim Kho thiab Kev Rho Tawm Dej:
Cov qauv modular txhawb kev rhuav tshem thiab sib dhos sai (lub sijhawm zoo tshaj plaws rau kev rhuav tshem thiab sib dhos ≤10 feeb) rau kev ntxuav yooj yim;
Cov kav dej ntws yuav tsum tau khaws cia rau hauv cov qhov sib txawv ntawm cov saw hlau kom tiv thaiv cov dej seem tom qab yaug. Qhov tsim qhib ntawm cov saw hlau tuaj yeem txhim kho CIP (huv si) kev ua haujlwm tau zoo los ntawm 60%;
Kev Tiv Thaiv Sealing Txhim Kho Dua Tshiab:
Cov khoom siv bearings siv lub labyrinth + daim di ncauj ob lub foob, ua tiav qib IP69K tsis pub dej nkag nrog lub thickness thaiv ≥0.5 hli. Yuav tsum tiv thaiv cov khoom khov thiab cov kua kom tsis txhob nkag mus; txwv tsis pub cov qauv ntsia hlau uas pom tsis tau kom tsis txhob muaj qhov sib txuas ua qhov chaw tsis pom kev.

IV. Cov Txheej Txheem Ua Haujlwm rau Kev Ntxuav thiab Lubrication

1. Cov Kev Cai Sib Xws ntawm Kev Ntxuav
Ua tau raws li cov txheej txheem ntxuav CIP nrog qhov kub ntawm 80-85 ℃ thiab siab ntawm 1.5-2.0 bar, tshem tawm ntau tshaj 99% ntawm cov khoom seem hauv 5 feeb; Sib xws nrog cov kuab tshuaj organic xws li ethanol thiab acetone, nrog rau cov tshuaj tua kab mob hauv qib zaub mov, tsis muaj txheej txheej tev tawm lossis cov khoom laus.
2. Cov Qauv Kev Huv Si rau Cov Tshuab Roj
Yuav tsum siv cov roj nplua nyeem NSF H1 qib zaub mov, lossis cov qauv roj nplua nyeem tus kheej (xws li cov menyuam roj nplua nyeem tus kheej ua los ntawm cov khoom siv UHMW-PE) yuav tsum tau txais yuav kom tshem tawm qhov kev pheej hmoo ntawm cov roj nplua nyeem kis rau cov zaub mov; Tsis pub ntxiv cov roj uas tsis yog zaub mov thaum lub sijhawm ua haujlwm saw, thiab cov roj nplua nyeem qub yuav tsum tau muab tshem tawm kom huv si thaum lub sijhawm txij nkawm kom tsis txhob muaj kev kis kab mob hla.

V. Cov Lus Qhia Txog Kev Xaiv Thiab Kev Txij Nkawm

1. Txoj Cai Xaiv Raws Li Qhov Xwm Txheej

2. Cov Ntsiab Lus Tseem Ceeb Txog Kev Txij Nkawm
* Kev Ntxuav Txhua Hnub: Tom qab ua haujlwm, tshem tawm cov seem ntawm cov qhov sib txawv ntawm cov saw hlau thiab cov nplaim ntawm cov menyuam. Ntxuav nrog lub zog siab thiab ziab kom huv si kom tiv thaiv cov dej noo thiab cov kab mob loj hlob.
* Kev Tshuaj Xyuas Tsis Tu Ncua: Hloov cov saw hlau tam sim ntawd thaum nws qhov ntev tshaj 3% ntawm qhov ntev ntsuas. Tib lub sijhawm kuaj xyuas cov hniav sprocket kom tiv thaiv kev hnav sai sai los ntawm kev siv cov khoom qub thiab tshiab ua ke.
* Kev Txheeb Xyuas Kev Ua Raws Cai: Dhau qhov kev sim ATP biofluorescence (RLU tus nqi ≤30) thiab kev sim microbial challenge (residue ≤10 CFU/cm²) kom ntseeg tau tias cov qauv kev huv huv tau ua tiav.

Xaus Lus: Tus Nqi Tseem Ceeb ntawm Cov Hlua Hlua Huv Si
Kev huv thiab kev nyab xeeb ntawm cov tshuab ua zaub mov yog ib qho project uas muaj txheej txheem. Raws li ib qho tseem ceeb ntawm kev sib kis, kev ua raws li cov saw hlau dov ncaj qha txiav txim siab qhov kev nyab xeeb ntawm cov khoom noj khoom haus kawg. Kev ua raws li cov qauv thoob ntiaj teb hauv kev xaiv cov khoom siv, kev tsim qauv tsis muaj kev sib txhuam, thiab kev saib xyuas tus qauv tsis yog tsuas yog txo qhov kev pheej hmoo ntawm kev ua qias tuaj xwb tab sis kuj ua tiav kev txhim kho ob qho tib si hauv kev nyab xeeb zaub mov thiab kev ua haujlwm zoo los ntawm kev txo lub sijhawm ntxuav thiab txuas ntxiv lub neej ua haujlwm. Kev xaiv cov saw hlau dov huv uas tau ntawv pov thawj los ntawm EHEDG thiab FDA yeej tsim thawj qhov kev thaiv kev huv rau cov tuam txhab ua zaub mov.
