Solvent Resistant Polyurethane Pre-polymer Rau Printing Rollers

Solvent resistant Polyurethane rollers yog cylindrical rollers coated nrog cov khoom siv elastomer. Cov tub ntxhais sab hauv, nyob ntawm daim ntawv thov, tuaj yeem raug khawb, dents, corrosion, thiab lwm yam kev puas tsuaj. Cov txheej polyurethane muab cov khoom siv sab hauv uas tiv thaiv cov tub ntxhais sab hauv, nrog rau kev puas tsuaj thiab kev cuam tshuam lub zog. Cov rollers no tau siv dav hauv ntau cov txheej txheem tsim khoom los ua haujlwm xws li:

Kev luam ntawv

Kev xa khoom

Squeezing

Nias

Laminating

Pub

Tshaj tawm

Polyurethane yog cov khoom siv dav siv elastomer rau cov menyuam. Los ntawm kev sib xyaw ntau hom thiab sib npaug ntawm cov khoom xyaw sib xyaw, ntau yam khoom siv kho tshuab tuaj yeem ua tiav kom haum rau cov ntawv thov tshwj xeeb. Cov khoom uas xav tau tshaj plaws ntawm polyurethane suav nrog nws qhov toughness, siab impingement tsis kam, poob siab absorbing, thiab qaug zog kuj.

Polyurethane rollers muaj cov tshuaj zoo, tshwj xeeb tshaj yog cov kuab tshuaj tiv thaiv zoo rau diesel, roj av, lubricating roj, kerosene, dej cawv thiab ntsev tov.Polyurethane yuav tsum muaj cov viscosity txaus, vim tias nws tuaj yeem ua kom zoo number case hloov thiab inking zog thaum lub sij hawm luam ntawv, thiab nws cov khoom zoo ink-phooj ywg tuaj yeem luam tau zoo.

Cov tsos thiab xim yog ci, lub colloidal nto yog zoo thiab du, thiab cov khoom siv colloidal thiab mandrel yog ruaj khov.Qhov loj ntawm cov menyuam roj hmab yog nruj me ntsis tswj, thiab qhov loj yuav tsis sib txawv heev nyob rau hauv txawv kub thiab av noo tej yam kev mob. Nws tuaj yeem hloov mus rau qhov kub thiab av noo ib puag ncig ntawm lub tshuab luam ntawv rhiav nyob rau sab qab teb thiab qhov txias thiab qhuav huab cua nyob rau sab qaum teb.

Daim ntawv thov cov yam ntxwv ntawm cov kuab tshuaj tiv thaiv polyurethane cov menyuam

1.Qhov tsos thiab xim yog ci, lub colloidal nto yog zoo thiab du, thiab cov khoom siv colloidal thiab mandrel tau ruaj khov. Kev tswj xyuas nruj ntawm cov menyuam roj hmab loj, qhov loj yuav tsis sib txawv heev hauv qhov sib txawv ntawm qhov kub thiab txias. tuaj yeem hloov mus rau qhov kub thiab av noo ib puag ncig ntawm lub tshuab luam ntawv rhiav nyob rau sab qab teb thiab txias thiab qhuav huab cua nyob rau sab qaum teb.

2.Qhov hardness Performance index ntawm hnyav kuj polyurethane cov menyuam yog dav, los ntawm HSA15 mus rau HSD80, uas muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm ntau hom tshuab luam ntawv rau hardness ntawm roj hmab rollers.

3.Cov colloid siv rau cov kuab tshuaj tiv thaiv polyurethane cov menyuam muaj cov viscosity txaus, tab sis cov roj hmab cov menyuam muaj cov cwj pwm zoo thiab cov khoom siv inking thaum lub sij hawm luam ntawv, thiab lawv cov cwj pwm zoo hauv cov khoom tuaj yeem txhim kho kev luam ntawv zoo.

4.Solvent resistance polyurethane cov menyuam muaj cov khoom siv tshuaj zoo, tshwj xeeb tshaj yog cov kuab tshuaj tiv thaiv zoo rau diesel, roj av, lubricating roj, kerosene, cawv thiab saline daws.

5.Solvent resistance polyurethane cov menyuam muaj lub cev zoo. Kev siv cov roj hmab ntev ntev yuav tsis tawv lossis muaj hnub nyoog, thiab lawv muaj kev tsim kua muag zoo, rov ua haujlwm zoo, thiab kev ua haujlwm zoo. Yog li ntawd, lawv muaj lub neej ua haujlwm ntev, yooj yim khaws cia, thiab kev cia ntev ntev tsis cuam tshuam rau kev siv; lawv tuaj yeem tiv taus kev kub siab, kev kub ceev, thiab cov av noo ntau lawm ib puag ncig.Kev sim tau pom tias lub zog tensile ntawm polyurethane roj hmab rollers yog 3 zaug thiab 5 npaug ntawm cov roj hmab roj hmab rollers; compression deformation thiab resilience zoo dua; thiab kev pab cuam lub neej ntawm polyurethane roj hmab rollers yog ntau tshaj 3 npaug ntawm cov kuab tshuaj zoo tib yam polyurethane cov menyuam.

6.Solvent resistance polyurethane roller muaj hydrophilicity zoo heev, yog li lawv tuaj yeem siv los ua cov roj hmab rau cov dej thiab dej cawv dampening systems.

7.Solvent resistance polyurethane cov menyuam muaj lub siab ua kua muag, yog li lawv tiv taus shear.

Kev tsim khoom ntawm cov menyuam yaus polyurethane yog cov txheej txheem ncaj qha uas suav nrog kev tsim cov tub ntxhais cov tub ntxhais, sib npaug, sib xyaw polyurethane, kev sib txuas, tsev, kho, machining, thiab kev soj ntsuam zoo. Cov txheej txheem no zoo ib yam li siv rau lwm hom roj hmab rollers. Qhov sib txawv tseem ceeb yog nyob rau hauv lub npog-tsev theem, qhov twg cov polyurethane resin nyob rau hauv cov kua.

Roller Core Fabrication thiab Kev Npaj-Hlau yog hom khoom siv ntau tshaj plaws rau kev ua cov menyuam cores.

Roller Balancing- Cov tub ntxhais cov tub ntxhais tuaj yeem dhau los ua qhov tsis sib xws hauv ob txoj hauv kev: static thiab dynamic imbalance. Static imbalance yog piav raws li cov menyuam dov mus rau nws qhov hnyav sab thaum ua kom tig ywj siab. Dynamic imbalance yog lub cim ntawm lub pob zeb txav los yog kev co thaum cov menyuam tig mus rau nws txoj haujlwm ceev.

Kev npaj polyurethane-

Kev sib khi- Kev sib khi yog cov txheej txheem uas cuam tshuam nrog cov roj hmab npog rau saum npoo ntawm cov menyuam tub ntxhais. Nws yog ua los ntawm kev siv cov tshuaj sib txuas cov neeg sawv cev uas ua raws li cov txheej txheem ntawm cov menyuam tub ntxhais.

Kho thiab txias- Kev kho yog txheej txheem ntawm kev tsim kev sib txuas ntawm cov saw hlau ntawm cov elastomer tebchaw.

Machining -Cov txheej txheem no smooths nto ntawm cov cam khwb cia polyurethane rollers los ntawm kev tshem tawm cov cheeb tsam protruding thiab flashings.

Polyurethane Compound Zoo Testing- Feem ntau cov chaw tsim khoom loj polyurethane rau cov menyuam muaj peev xwm kuaj hauv tsev los saib xyuas qhov zoo ntawm cov cam khwb cia polyurethanes ntawm lawv cov khoom siv. Polyurethanes raug soj ntsuam los ntsuas lawv cov khoom tseem ceeb, xws li hardness, abrasion resistance, thiab lub zog tsim kua muag. Lwm txoj hauv kev sim yog siv rau cov ntawv thov tshwj xeeb, xws li kev laus zuj zus thiab kev ntsuas kub ua haujlwm rau cov ntawv thov kub.

Qhov ntau lawm yog tswj los ntawm DCS system, thiab packing los ntawm tsis siv neeg filling tshuab. Pob yog 200KG / Nruas lossis 20KG / DRUM.

Khaws rau hauv qhov chaw txias thiab qhuav thiab siv kom sai li sai tau tom qab qhib;

Yog tias nws tsis tuaj yeem siv rau ib zaug, nws yuav tsum tau ntim nrog nitrogen;

Qhov thib ob qhib yuav tsum tau siv rau defoaming, thiab thawj lub sij hawm cia yog rau lub hlis.
