High-cov ntsaws ruaj ruaj thiab roj ntsaws ruaj ruaj: Ua tsaug rau nws lub siab ua haujlwm siab, kub tsis kam, thiab kev tshaj tawm zoo heev, nws tau siv dav hauv cov tshuab hnyav, hydraulic systems, aerospace, thiab lwm yam.
Rollers thiab log: Cov cuab yeej ua haujlwm nyob rau hauv cov xwm txheej hnyav xav tau kev ua haujlwm siab hauv kev ua haujlwm kub, muaj peev xwm thauj khoom, cuam tshuam tsis kam, hnav tsis kam, hydrolysis tsis kam, thiab dynamic stability. NDIthane elastomer ua tau raws li cov cai no, yog li nws feem ntau siv rau cov menyuam thiab cov log.
Lwm qhov chaw: Cov khoom siv Precision, siab - txoj kev tsheb ciav hlau ceev, thiab cov khoom siv tsheb uas yuav tsum tau ua kom muaj zog thiab qaug zog; industrial roj hmab yob ua haujlwm ntawm qhov kub thiab txias los yog nyob rau hauv ib puag ncig tshuaj lom neeg hnyav; thiab siab -kev ua tau zoo kis tau tus mob thiab siv sij hawm siv, leveraging NDIthane qhov seem stability, tsis yog -slip zog, thiab qaug zog kuj.
Dab tsi yog qhov tsis zoo ntawm NDI Elastomers?
Tus nqi siab: NDI raw khoom kuj kim, thiab cov txheej txheem synthesis ntawm NDI elastomers yog complex. Nws cov nqi raw khoom yog siab dua li ntawm MDI thiab TDI, uas yog tus nqi tseem ceeb tshaj tus tsav tsheb. Yog li ntawd, cov khoom siv polyurethane ua los ntawm NDI yog tus nqi qis. Txawm li cas los xij, nrog kev nce qib txuas ntxiv hauv kev tsim cov thev naus laus zis thiab kev ua lag luam maj mam, tus nqi ntawm NDI xav tias yuav poob rau lub sijhawm.
Cov kev cai ua kom nruj: NDI prepolymers muaj qhov ua haujlwm siab thiab feem ntau yog lub lauj kaub luv luv. Cov khoom sib xyaw ua ke tuaj yeem pib ua kom tuab li ntawm feeb lossis kaum vib nas this, ua rau muaj kev sib tw zoo rau casting, degassing, thiab sau cov pwm nyuaj. Lub caij no, taug qab cov dej noo hauv cov khoom siv raw, cov khoom ntim, lossis txawm tias huab cua nyob ib puag ncig tuaj yeem ua rau npuas, tsis xws luag, thiab kev ua haujlwm hnyav. Tag nrho cov ntaub ntawv yuav tsum tau ua kom lub cev qhuav dej nruj.
Cov kev txwv tsim: NDI elastomers feem ntau muaj nyob rau hauv cov qib siab hardness (feem ntau siab dua Shore A 90, txawm Shore D 50-70). Yuav luag tsis muaj qib qis- hardness (xws li Shore A 60–80), uas txwv tsis pub nws cov ntawv thov hauv cov teb uas xav tau softness thiab siab compression teeb. Txawm hais tias nws muaj lub zog siab, nws qhov kev hloov pauv siab ua rau nws "nqaij" thiab tsis tsim nyog rau cov xwm txheej uas yuav tsum tau ua kom mos elasticity.
Tsis zoo adhesion kev ua tau zoo: Vim NDI elastomers 'siab tshuaj stability thiab tsis tshua muaj zog nto, bonding NDIthane elastomers rau hlau los yog lwm yam substrates yog nyuaj dua li cov pa polyurethane. Cov txheej txheem tshwj xeeb tshwj xeeb thiab cov txheej txheem kho saum npoo feem ntau yog xav tau, thiab kev txhim kho ntawm cov txheej txheem sib khi sawv cev yog qhov kev sib tw loj.
