Yuav ua li cas xaiv cov khoom noj xis xis rau tsawg -} Qhov chaw ib puag ncig?

Qhov tseem ceeb Logic rau Tsawg - Cov Khoom Siv Kub Kub Kub (0 Qib rau -40 Qib)

 

Tsawg qhov kub tau yooj yim ua rau cov khoom embrittlement, ploj ntawm elasticity, thiab qhov tob tob. Cov kev txiav txim siab tseem ceeb rau cov khoom xaiv muaj xws li: elasticity tsis kam, nyob ruaj khov, thiab cov khoom muaj nuj nqis}, thiab cov suab nrov txo cov kev xav tau.

 

Cov ntaub ntawv tseem ceeb rau tsawg - kub ua haujlwm thiab kev siv cov xwm txheej:

 

1. Xav tau: txias -} tiv taus tus pu (polyurethane)

 

Cov txiaj ntsig zoo: elasticity zoo heev (tswj hwm ntug dej hiav txwv 60}}

 

Cov ntawv thov: Feem ntau cov qes - qhov chaw ib puag ncig. Rau nruab nrab - rau - siab}}}- hardness caster (85- 95A); Rau cov suab nrov txo cov suab (chaw muag tshuaj, kuaj), xaiv lub tais mos (60-80a); Rau cov ntawv thov tsawg-kub (hauv qab -30 degree), qhia kom meej tus qauv nrog "tsawg-kub tsis kam-50 degree."

 

2. Qhov thib ob xaiv: Taushten Nylon 66 (PA66)

Cov txiaj ntsig zoo: Hloov kho (nrog iav fiber ntau / elastomer) rau kev txhim kho kev ua kom nruj (roj yuav tiv taus, roj / tshuaj lom neeg kuj, thiab tus nqi qis.

 

Cov kev txwv: kev nqus dej siab (yuav tsum tau xaiv qhov qis {{0} {{}}}}}}}}} Txoj kev nqus khoom hauv qab -30 degree.

 

Applications: Short-term low temperatures (0°C to -20°C), high-load-bearing industrial applications (>500kg), cov nplaim thaiv cov ntxhib, thiab tus nqi -} Cov ntawv thov rhiab.

 

3. Lwm txoj hauv kev: Cold {{- Cov roj hmab resistant (nitrile - buttriene nitrile / Silicone)

Cov txiaj ntsig: NBR yog roj - tsis kam (zoo elasticity (zoo elasticity ntawm {}} 30 degree); Silicone yog qhov kub heev - tiv taus (-qib siab mus rau 200 degree), muaj elasticity zoo, thiab yog cov khoom noj-qib.

 

Cov kev txwv: Cov hnav tsis zoo, qis thauj khoom - bearing muaj peev xwm (feem ntau<200kg).

 

Daim ntaub ntawv: Lub teeb {- phoo ntawv chaw huv (zaub mov txias / chaw txias txias); Huab tsis kub tsawg nrog kev xav tau ntawm elasticity (yuav tsum tau lub log tsheb hlau).

 

Zam: dog dig nylon 6 (nquag tawg rau hauv qab -10 degree), PVC (hardens thiab tawg ntawm tsawg kub), thiab tsis muaj qhov tsis pom zoo hauv qab -20 degree).

 

Cov ntsiab lus tseem ceeb ntxiv:

Hardness Matching Load Capacity: For heavy loads (>300Kg / log), xaiv siab - hardness (85-95a) pu lossis tawv pa66; Rau lub teeb ntsaws (<100kg/wheel), choose soft PU (60-80A) or rubber.

 

Log Core / bracket: Xaiv ib tus hlau / cam khwb cia hlau log tub ntxhais (kom tiv thaiv kom tsis txhob muaj embittlement); Txias - rolled steel / stainless hlau bracket; Tsawg -} kub roj rau bearings.

 

Cov kev xav tau tshwj xeeb: Xaiv cov log nrog anti - hos grooves grooves grooves rau ntub thiab nplua chaw; choose non-porous, easy-to-clean PU for clean areas; Paub meej tias PU cov tshuaj tiv thaiv lossis xaiv PA66 rau tshuaj -} tiv taus cov ntawv thov.

 

Cov ntsiab lus ntawm kev xaiv ua ntej:

Hauv qab no - 30 degree: txias-resistant hloov pU (hom polyether).

- 10 Degree rau -30 degree: ToCreeded Pa66 lossis Txheem PA66 lossis cov qauv hluav taws xob txias / nqi).

Lub teeb - phoo, nyob ntsiag to, thiab huv si {{free - tawm pU los yog nitrile / Silicone Roj Hmab.

Short-term low temperatures (>-20 degree), cov nqi hnyav, thiab tus nqi qis: Toughed PA66.

 

Cov ntsiab cai tseem ceeb: Ua ntej txias txias -} tiv taus hloov pauv pu; Xav txog kev ua kom nruj pa66 rau cov khoom siv hnyav thiab raug nqi -} Cov ntawv thov rhiab; Xav txog cov roj hmab rau lub teeb {{3} log thiab huv; Thiab zam cov qauv plastics (pa6, pvc, thiab tsis tau muaj unmodified pp / PE).
