Daj Polyurethane Nrog Cam Khwb Hlau

Yantai Zhengyuan Polyurethane Co., Ltd. Tau tsim los rau hauv 2007 thiab tau cog lus rau cov kev tshawb fawb thiab kev tsim khoom ntawm polyurethane khoom txij li nws pib. Cov khoom lag luam tseem ceeb tsim muaj cov log polyurethane, polyurethane cua teateers, thiab lwm yam khoom siv roj av, thee tsuas, kev siv nyiaj npib mining, kev siv nyiajvees thiab lwm yam kev lag luam. Peb nyob hauv Yantai, Shandong, qhov chaw yug ntawm polyurethane khoom. Wanhah, muaj cov khoom lag luam Suav loj cov khoom lag luam, yog tseem nyob ntawm no. Peb muaj qhov zoo tshwj xeeb hauv ob leeg thev naus laus zis thiab cov khoom siv raw. Lub daj polyurethane nrog cam khwb cia hlau tsim tau txais kev qhuas tsis pom zoo los ntawm cov neeg siv khoom rau nws qhov zoo} Cov khoom lag luam zoo thiab tsim nyog tus nqi. Txais tos kom tuaj xyuas lub Hoobkas txhua lub sijhawm

1. Kev ceev faj rau kev ua kom daj polyurethane nrog cam khwb cia hlau
1) Nrum Hlau Matrix Kho
Deg huv si, tsis muaj roj stains lossis xeb (residual impurities tuaj yeem ua rau kev txiav txim siab ntawm txheej)
Qhov ntsuas kub preheating yuav tsum tau tswj tsis pub dhau ib qho kev tsim nyog
Cov qauv tsim qauv ntawm cov hlau cam khwb cia yuav tsum tsim nyog, nce cov neeg kho mob tiv thaiv, thiab tiv thaiv delamination
2) Polyurethane Txheej Txheej Txheem
Xaiv cov xim daj tiv thaiv polyurethane expolymer, dog dig daj pigments yog nquag mus rau UV kev laus
Qhov piv tau ntawm prepolymer los kho tus neeg sawv cev yuav tsum tau tswj hwm kom zoo, txwv tsis pub nws yuav dhau los lossis nplaum
Lub ncuav qhov ntsuas kub yuav tsum tau tswj hwm ntawm 80 ± 5℃c (yog tias qhov ntsuas kub dhau, yuav ua tsis tau zoo, nws yuav ua rau muaj kev sib cav sib ceg thiab tsim cov npuas)
Kuj them sai sai rau defoaming thiab kho lub sijhawm
3) Kev Soj Ntsuam Zoo
Hardness Kuaj: Ntug Dej Hardness A 90-95 (Kev Zam Txim ± 2A), nrog 3 cov ntsiab lus piv txwv ib pob
Daim ntawv qhia nplaum: Siv hniav txiav yeeb yam, polyurethane txheej tsis muaj kev ua haujlwm
Dynamic sib npaug kho: cov rollers ceev yuav tsum tau ua dynamically sib npaug
2. Kev ceev faj thaum siv cov polyurethane uas muaj cam khwb cia hlau
1) Nco ntsoov tias cov load ntau tshaj plaws yog tsawg dua lossis sib npaug ntawm cov neeg tsim muaj peev xwm (piv txwv li cov menyuam muaj ntau dua ntawm 10 tons, tab sis yeej siv tsawg dua lossis sib npaug nrog 8 tons)
2) Qhov chaw nruab nrab ntawm lub ntiajteb txawj nqus ntawm lub nra yuav tsum yog nruab yuav tsum yog nruab, nrog eccentricity tsawg dua 5% (eccentricity ua rau lub siab ntuag)
3) Long term use temperature should be controlled between -30 ° C and+80 ° C (softening occurs when>100 Qib C, thiab Nyuaj Nyuaj tshwm sim thaum<-40 ° C)

Cim npe nrov: Daj Polyurethane nrog cov hlau cam khwb cia, Tuam Tshoj, tuam ntxhab, Hoobkas, tus nqi qis, ua nyob rau hauv Suav teb
