Dab tsi yog qhov sib txawv hauv lub peev xwm thauj khoom ntawm cov casters ua los ntawm polyurethane (pA)?

Muaj qhov sib txawv tseem ceeb hauv load-bearre muaj peev xwm ntawm cov casters ua los ntawm polyurethane (pA). Qhov sib txawv no los ntawm cov qauv molecular, cov yam ntxwv lub cev thiab cov ntawv thov kev ua yeeb yam ntawm ob cov khoom.

 

1. Kev tshuaj xyuas ntawm cov ua rau sib txawv

 

1. Cawv ntawm cov khoom siv lub cev ntawm cov ntaub ntawv

 

Polyurethane (PU):

 

PU yog elastomer, thiab cov qauv molecular muaj cov khoom muag thiab nyuaj ntu. Qhov nyuaj ntu muab lub zog thiab ntu mos muaj cov elasticity. Tus qauv no txiav txim siab tias nws cov kabmob-cov kabmob yog nyob ntawm "Elastic deformation dispersing siab", tab sis kev sib npaug ntawm cov ntu nyuaj yog txwv (feem ntau 30% -50%. Tom qab tshaj 300kg, ntu muag muag yog nquag ua rau ntau dhau los, ua rau muaj kev ntxhov siab ntawm lub log (xws li cov kev ntxhov siab thiab kev ua kom tsis pom kev.

 

Piv txwv li: Hauv cov xwm txheej kho mob, yog tias lub log pu tau siv los nqa ntau tshaj 300kg ntawm cov khoom siv kho mob loj (nruab nrab ntawm lub log npoo yuav tshwm sim tom qab 1-2 hlis, ua rau cov khoom siv los qaij.

 

Nylon (PA):

 

Nylon yog ib tug crystalline polymer nrog kaw kom nruj me ntsis. Cov nylon siv hauv cov casters yog feem ntau txhawb nylon (ntxiv 10% -30% iav fiber ntau), uas tau txhim kho cov crystallinity thiab rigidity. Nws cov kabmob-cov kabmob tso siab rau "cov qauv nruj uas tiv thaiv", thiab cov molecular txoj saw hlau tsis yooj yim ncab lossis tawg. Txawm hais tias nws yog nqa tau ntev, qhov deformation tus nqi ntawm lub log lub cev feem ntau tsawg dua 1%, thiab qhov ruaj khov yog deb dhau ntawm tus PU.

 

Piv txwv li: Muaj cov khoom siv hluav taws xob hnyav (xws li lub tsev kho mob rho nyiaj hloov tsheb, nrog rau tag nrho cov log tsheb, nrog rau kev siv nylon kom tsis tu ncua li 1 xyoos tsis muaj kev pom tseeb.

 

2. Qhov sib txawv hauv kev thov cov xwm txheej chaw haujlwm

 

PU log:

 

Lub hom phiaj qub ntawm cov qauv tsim yog kom sib npaug, poob siab, cov rooj tog tsis txaus ntseeg (xws li cov rooj tog hauv nroog Yog tias raug yuam kom siv rau kev thauj khoom hnyav, nws yuav ua kom muaj kev laus vim cov khoom siv nkees nkees thiab ua kom lub neej pabcuam rau 1/3 ntawm qhov xwm txheej ib txwm muaj rau.

 

Nylon Log:

 

Muab tso rau "Cov khoom siv hnyav, hnav-tiv taus, feem ntau tsim nyog rau cov kev cob qhia hnyav thauj khoom, feem ntau haum thiab kev ua haujlwm logistics cov chaw khaws khoom lag luam. Lub thauj khoom-cov kabmob kev ua tau zoo yog zoo sib xyaw nrog lub neej pabcuam (nws tseem tuaj yeem ua haujlwm ruaj khov hauv qab hnyav load).

 

2. Cov lus taw qhia rau kev xaiv cov kabmob xaiv hauv cov ntawv thov siv

 

Nruab Nrab-Lub Teeb Nraws (tsawg dua los yog sib npaug, kev xav tau lub log tsheb (txog 50kg

 

Heavy load scenarios (>300Kg): piv txwv li, cov tsheb kho mob hnyav hloov chaw (li 500kg log ib sab ntawm lub tsev kho mob

 

Hauv cov ntsiab lus, cov khoom siv thauj khoom ntawm nylon (pa) casersers deb tshaj li ntawm polyurethane (pu) cov txiaj ntsig, thiab lawv tau pom tseeb hauv kev ruaj khov ruaj khov. Thaum xaiv, koj yuav tsum phim raws li cov load tiag tiag kom tsis txhob muaj cov cuab yeej tsis ua haujlwm lossis kev phom sij kev nyab xeeb vim kev xaiv tsis yog.
