Yuav ua li cas txhawm rau txhim kho lub siab - kub ua haujlwm ntawm polyurethane casters?

Txhawm rau hais tias qhov tsis txaus siab - kub ua haujlwm ntawm polyurethane casters, peb txoj kev hloov kho, qauv hloov kho, thiab cov txheej txheem hloov kho. Cov hau kev no tuaj yeem siv los txhim kho lawv qhov siab- tsis kam thiab nthuav lawv cov ntawv teev npe:

Ua ntej, ua kom zoo rau cov polyurethane formula thiab qhia siab formula thiab qhia siab - kub {1} {estive cov khoom xyaw. Thaum lub sij hawm Polyurethane Prepolymer Synthesis Cov theem, pa polyols tuaj yeem hloov nrog lub siab- kub thiab polyethersulffone polyol). Cov polyols muaj ntau dua molecular saw ruaj khov thiab tuaj yeem tsa cov khoom siv lub siab {{6 {{{{}} 15}}}}} 15} Ib txhij, ntxiv siab siab - kub {{{{{{{-}- ({} Cov khoom muag Isocyanate hloov kho (xws li xylylene diislene diisocyanate) kuj tseem tuaj yeem qhia kom nce cov kab ke ntawm polyurethane, txuas ntxiv txhim kho nws qhov kev ruaj khov siab.

Thib ob, txhim kho cov qauv tsuj las kom txhim kho tshav kub dissipation thiab deformation tiv taus. Lub Cleaster yog tsim nrog "honeycomb hollow tus qauv" los tiv thaiv tshav kub kub dispipation thaum lub zog kub thiab tiv thaiv kev kub ntxhov hauv nroog siab thiab kev kub ntxhov} Ib qho hlau los yog fiberglass txhawb nqa cov pob txha pob tub luam tawm yog nyob rau hauv cov tsuj. Lub cev pob txha siab - lub zog txhawb tiv thaiv tiv thaiv kev muag khoom los ntawm kev muag muag thiab muab tso rau hauv dej ntau dua, tswj lub tshuab ua kom huv.

Thib peb, lub siab - kub -} {Resistant composite txheej yog siv los cais tawm ntawm cov tshuab nqus kub. Siab - kub {4 {}}}}}}} Cov khaub ncaws polytetrafene (ptfe) lossis txau mus rau hauv polyurethane tsuj qaum. Cov txheej txheej no, uas tuaj yeem tiv thaiv kub siab tshaj 200 degree, sau ib qho kev tiv thaiv tuab ntawm cov chaw kub mus rau cov khoom siv polyurethane sab nraud. Lawv kuj tiv thaiv kev sib cuag ncaj qha ntawm cov tsuj thiab cov roj thiab impurities nyob rau hauv high- qhov chaw ua haujlwm lub neej.

Plaub, lub log HUB thiab cov kabmob cov kabmob teeb tsa tau txhim kho kom tau raws li siab -}}}}}}}} qhov kub thiab txias yuav tsum tau ua. Hloov cov tsoos hlau log hubs uas muaj kub {2} Cov khoom kub (xws li txhuas alloy) los txo cov cua sov uas muaj txiaj ntsig ntawm lub log ntawm qhov kub siab; Siv high - tsis kam txais cov kabmob siab, kom tsis txhob muaj qhov sib sib zog nqus cov kabmob, kom tsis txhob muaj qhov ua tsis tau zoo high {{{{}} kub ua hauj thiab hloov tau.
