Cov log tsheb zoo li "khau" ntawm rooj tog lossis khoom siv, yog li kev xaiv cov khoom siv zoo ua rau lawv yooj yim txav mus los thiab tiv thaiv hauv av. Hauv qab no, peb yuav siv sijhawm 3 feeb los qhia koj yuav ua li cas paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo ntawm peb cov ntaub ntawv tseem ceeb ntawm nylon, polyurethane, thiab roj hmab, los muab cov lus qhia yuav khoom raws li thaj chaw.
1. Txheej txheem cej luam ntawm cov khoom siv
1). Nylon (PA)
• Cov Lus Tseem Ceeb: Nyuaj, Ua Haujlwm Hnyav, Nrov Nrov
• Cov yam ntxwv: Muaj zog heev, muaj peev xwm dais tau hnyav zoo heev, tab sis lub suab nrov nrov; tsis yooj yim hnav tab sis tsis yog "mos mos". Tom qab thawb thiab rub ntev nws yuav khawb hauv pem teb ntoo lossis cov khoom siv ceramic.
• Piv txwv li: Ib yam li lub log tsheb uas khiav tawm ntawm txoj kev, nws tuaj yeem nqa tau cov khoom hnyav tab sis nws suab nrov heev.
2). Polyurethane (PU)
• Cov Lus Tseem Ceeb: Elastic, Quiet, Versatile
• Cov yam ntxwv: Kev ywj pheej ntawm cov yas thiab roj hmab, suab nrov tsawg, tiv taus roj thiab hydrolysis. Nws tsim nyog rau cov chaw ua haujlwm tsis muaj plua plav, chaw soj nstuam, tsev kho mob, thiab lwm qhov chaw uas muaj cov kev cai nruj; zoo rau hauv pem teb, tsis tawm cov cim dub.
• Kev piv txwv pom: Ib yam li lub hauv paus nruab nrab ntawm khau khiab, nws ruaj khov thiab ntsiag to.
3). Roj Hmab (NR/SBR)
• Cov Lus Tseem Ceeb: Mos, Nyuaj, Pheej Yig
• Cov yam ntxwv: Nws tiv thaiv kev plam thiab tuav tau zoo, tsis plam thaum thawb cov khoom hnyav; nws nqus tau kev poob siab, ntsiag to thiab pheej yig. Qhov tsis zoo yog nws laus thaum raug tshav ntuj ntev thiab hloov pauv thaum muaj khoom hnyav.
• Kev piv txwv pom: Ib yam li cov log tsheb ntsiag to ntawm lub tsheb tsev neeg, nws yuav tsum tau thawb "ntsiag to" thiab zam kev thauj khoom ntau dhau mus sij hawm ntev.
2. Nkag Siab Yuav Ua Li Cas Xaiv Nrog Ib Lub Rooj
| Cov Kev Xav Tau ntawm Qhov Xwm Txheej | Cov Khoom Siv Pom Zoo | Vim li cas |
| Cov khoom hnyav hauv Hoobkas, cov plag tsev cement | Nylon | Muaj zog thauj khoom, hauv pem teb tiv taus khawb |
| Cov tsev kho mob, cov chaw kuaj mob, cov chaw hauv tsev so | Polyurethane | Nyob ntsiag to + tiv thaiv pem teb + tiv thaiv corrosion |
| Cov txee cia khoom hauv tsev, cov txee thawb chaw ua haujlwm | Roj Hmab | Nyob ntsiag to, tiv thaiv kev plam, tsis ua rau puas tsuaj rau hauv pem teb ntoo, pheej yig |
| kev raug tshav ntuj thiab nag sab nraum zoov | Polyurethane (hloov kho UV tiv taus) | Kev laus tiv taus, roj hmab yooj yim tawg hauv qab hnub |
| Yuav tsum tau muab lub nres tso rau | Txhua yam khoom siv, tsom mus rau qhov qauv nres | Lub neej ntawm lub ncoo nres tseem ceeb dua li cov khoom siv ntawm lub log |
3. Peb Kauj Ruam Kev Yuav Khoom Siv Mnemonic
1. Tshawb xyuas hauv pem teb: Rau cov plag tsev ntoo thiab cov khoom siv av nplaum, koj tuaj yeem xaiv PU lossis roj hmab; rau cov plag tsev cement lossis hlau, nylon yog qhov tsim nyog.
2. Mloog ib puag ncig: Rau cov chaw ua haujlwm thiab tsev kho mob uas xav tau "tsis muaj suab nrov", yuav tsum tsis txhob siv nylon.
3. Ntsuas qhov hnyav: Lub peev xwm thauj khoom ntawm ib lub caster ≥ (qhov hnyav tag nrho ntawm cov khoom siv ÷ 3), tawm hauv qhov kev nyab xeeb txaus.
Kev piav qhia luv luv hauv ib kab lus
Cov khoom hnyav uas tsis muaj kev txhawj xeeb txog suab nrov—xaiv nylon; xav kom nyob ntsiag to thiab huv si—xaiv polyurethane; xav kom txuag nyiaj tab sis nyob ntsiag to—xaiv roj hmab. Sib phim cov khoom siv rau qhov xwm txheej, thiab cov casters yuav tsis yog qhov kev xaiv nyuaj lawm.
