Kev Sib Tham Txog Kev Sib txhuam coefficient ntawm Polyurethane Rollers thiab hauv av

Peb txheeb xyuas qhov sib txhuam coefficient ntawm lub log polyurethane thiab cov cement hauv pem teb, thiab tsim cov hardness tsis ntawm polyurethane log raws li kev sib txhuam quab yuam thaum lub sij hawm dov. Txawv TDI, MDI, thiab NDI cov ntaub ntawv kuj cuam tshuam rau kev sib txhuam muaj peev xwm. Niaj hnub no, tus editor yuav txheeb xyuas nrog koj cov kev sib txhuam coefficient ntawm polyurethane rollers thiab hauv av. Polyurethane cov menyuam, polyurethane kev sib txhuam log, polyurethane log kev sib txhuam coefficient. Qhov xaus ntawm kev sib txhuam coefficient ntawm polyurethane coated log thiab cement pem teb yog thawj zaug tshaj tawm:
Kev sib txhuam coefficient ntawm cov roj hmab log thiab cov cement pem teb yog hais txog {{0}}.08, thiab qee lub tuam txhab suav nws raws li 0.56. Kev ua haujlwm ntawm cov cement hauv pem teb yuav tsum xav txog qhov sib txhuam coefficient ntawm dov, uas qhia tau hais tias nws tsawg dua qhov sib txhuam coefficient ntawm 0.8. Tsis muaj tus nqi ruaj khov rau kev sib txhuam coefficient nrog cov cement hauv pem teb, vim tias ob qho tib si polyurethane cov menyuam thiab cov cement pem teb tsis muaj qhov tsim nyog coefficient. Nyob rau hauv cov nqe lus ntawm kev hnav tsis zoo, polyurethane tseem zoo heev.
Tau kawg, qee zaum peb kuj yuav tsum xav txog kev sib txhuam coefficient ntawm polyurethane cov menyuam thiab cov yav dhau los, feem ntau suav ua 0.03-0.05. Tib lub sijhawm, peb kuj yuav tsum xav txog tias txoj kab uas hla ntawm koj cov menyuam polyurethane thiab qhov hnyav ntawm cov hlau nqa ntawm cov menyuam yog qhov tsis paub tseeb.
Cov yam ntxwv ntawm polyurethane encapsulation nplaum
Polyurethane, raws li cov khoom siv elastic, muaj cov yam ntxwv zoo, xws li kev ua haujlwm zoo, hnav tsis kam, thiab muaj peev xwm ua haujlwm siab. Nyob rau hauv cov nqe lus ntawm ntau lawm technology, polyurethane rollers yog tsim los ntawm kev siv tshuab tuag-casting. Piv nrog rau cov txheej txheem nchuav thiab txhaj tshuaj molding, cov khoom tau zoo heev txhim kho cov kabmob muaj peev xwm, kev khiav haujlwm ceev, tawg, thiab nplaum qhib cov yam ntxwv. Polyurethane rollers yog dav siv nyob rau hauv ntau lub lag luam, thiab lawv cov yam ntxwv ntawm cov khoom zoo tshaj cov kev txhaj tshuaj molding rollers. Lawv muaj cov yam ntxwv ntawm lub neej ua haujlwm ntev, tsis tshua muaj suab nrov, thiab muaj zog load-bearing muaj peev xwm.
Tom qab kev sim tiag tiag (nrog rau ntau yam ntaub ntawv thiab qhov kub thiab txias), qhov sib txhuam coefficient ntawm feem ntau siv TDI thiab MDI polyurethane log ntawm cov plag tsev tiaj tus thiab qhuav cement feem ntau qis dua {{0}}}.65. Rau conservatism, nws raug nquahu kom suav ntawm 0.6.
Lub elasticity ntawm polyurethane rollers yog ze ze rau ntau yam, nrog rau cov muaj pes tsawg leeg ntawm polyurethane, lub thickness ntawm polyurethane, thiab muaj lwm yam sib txuas; Nws kuj muaj feem xyuam rau qhov kub thiab txias, thiab qhov kub thiab txias sab nraud yuav cuam tshuam ncaj qha rau lub zog ntawm polyurethane. Yog hais tias lub hardness siab dhau lawm, lub ductility ntawm polyurethane rollers kuj tseem txwv. Polyurethane rollers muaj kev ua haujlwm zoo ntawm lub cev, thiab kev siv ib ntus ntawm cov roj hmab rollers tsis yooj yim rau tawv thiab muaj hnub nyoog, thiab muaj lub zog tsim kua muag thiab ua haujlwm zoo. Thiab polyurethane rollers tuaj yeem ua haujlwm nyob rau hauv ib puag ncig ntuj nrog kev ua haujlwm siab, kev sib hloov ceev, thiab qhov kub thiab txias; Haum rau ntau hom inks thiab ntim tshuab luam ntawv txoj kev, nws muaj qhov tshwj xeeb tsis kam rau cov tshuaj tiv thaiv nyob rau hauv ntau yam inks, phaj lubricants, thiab generator rau cov menyuam tu cov neeg ua haujlwm.
Cov khoom lag luam sib txawv ntawm cov khoom siv sib txawv yog tshwm sim los ntawm kev puas tsuaj sib txawv hauv kev lag luam sib txawv. Cov theem ntawm kev puas tsuaj ntawm ob yog cuam tshuam nrog lawv cov kev sib txhuam coefficient, uas yog hais txog tus nqi siv ntawm qhov zawv zawg kev sib txhuam quab yuam ntawm ob qhov chaw thiab lub zog ntsug ua haujlwm ntawm ib qho chaw. Lub tshuab sealing rau cov menyuam yog tus nqi siv rau kev khiav kev sib txhuam thiab kev sib txhuam kev sib txhuam, thiab kev tsav tsheb yuav tsum tau ntsuas ua ntej nws tuaj yeem ntsuas.
Kev sib txhuam coefficient loj ntawm polyurethane rollers muaj feem xyuam rau cov khoom siv raw khoom thiab cov txheej txheem saum npoo (roughness theem, ib puag ncig cov av noo, thiab lwm yam) ntawm cov ntaub ntawv sib cuag. Tsis tas li ntawd, vim muaj kev sib txhuam coefficients sib txawv ntawm cov rollers sib txawv, lawv kuj tseem cuam tshuam tam sim ntawd rau lawv lub zog, rebound quab yuam, thiab lwm yam. Nws yog ib qho tsim nyog los kho lawv cov kev sib txhuam coefficient thiab kev puas tsuaj, thiab xyuam xim rau manipulation ntawm lub caij no.
