Dab tsi yogNDIthane Elastomer?

Ntau tus neeg paub tias lub forklift log yog ua los ntawm lub log core (steel, hlau, aluminium, lossis yas) thiab cov khoom siv polyurethane. Txawm li cas los xij, thaum xaj polyurethane log, manufacturers feem ntau pom zoo NDIthane elastomer rau lub log tread.Yog li vim li cas cov tuam txhab yuav luag ib txwm pom zoo NDIthane elastomer? Thiab nws puas yog cov khoom siv tread rau koj lub log?

NDIthane elastomer yog tus kws tshaj lij, siab - cov khoom siv kawg. Nws hais txog polyurethane elastomer synthesized raws li NDI (1,5-naphthalene diisocyanate). Raws li qhov saum toj kawg nkaus -tier qeb ntawm polyurethane elastomers, nws muaj npe nrov rau nws cov khoom siv tshwj xeeb, ua haujlwm kub, thiab tiv thaiv hydrolysis. Nws feem ntau hu ua "siab-kev ua tau zoo polyurethane elastomer" lossis "engineering- qib polyurethane." NDIthane elastomer tsuas yog ib hom khoom siv polyurethane, feem ntau hu ua NDI polyurethane, NDI-based polyurethane, lossis NDI cov khoom.

NDI polyurethane muab kev ua tau zoo tshaj plaws thoob plaws lub rooj tsavxwm, tshwj xeeb tshaj yog rau monorail hoist tsav log, tau txais nws lub koob npe nrov li "tus huab tais ntawm hnav tsis kam" rau cov khoom siv mining. Ib qho piv txwv yog NDIthane 95, uas siv cov cam khwb cia steel log core nrog polyurethane tread. Nws ua haujlwm ruaj khov hauv qhov kub li ntawm -10℃mus rau 120 degree, boasts zoo heev txhua yam khoom, thiab muaj kev pab lub neej ntawm ntau tshaj 2,000 teev.

NDI (naphthalene diisocyanate) yog ib qho khoom siv raw khoom rau polyurethane, featuring high reactivity thiab zoo heev kub kuj. Polyurethane ua los ntawm NDI nthuav tawm lub zog zoo dua, hardness, thiab hnav tsis kam, ua rau nws zoo tagnrho rau cov khoom siv polyurethane siab xws li engineering plastics thiab tshwj xeeb elastomers.

Dab tsi yog Cov Khoom Tseem Ceeb ntawm NDI Polyurethane?

Toughness: Tsis tshua muaj siab tensile lub zog, tsim kua muag lub zog, thiab modulus, thaum tuav zoo elasticity thiab resilience, nrog zoo heev cuam tshuam kuj.

Thaum tshav kub kub tsis kam: Ntev -lub sij hawm kev pab kub mus txog 120℃-140 degree, nrog luv luv -lub sij hawm kam rau siab dua kub. Mechanical zog degrade tsawg heev ntawm qhov kub thiab txias, deb outperforming zoo tib yam polyurethane (feem ntau txwv rau<80°C).

Hydrolysis tsis kam: Tsis zoo li ntau lwm yam polyurethanes, nws qhia tau hais tias muaj zog tiv thaiv kub thiab av noo ib puag ncig, tiv taus hydrolytic degradation, thiab muaj kev pab lub neej ntev.

Dynamic kev ua tau zoo: Tsis tshua muaj kev sib txhuam sab hauv thiab tsis tshua muaj cua sov tsim. Nws tseem ruaj khov nyob rau hauv nquag compression thiab dabtsi yog khoov, ua rau nws zoo heev haum rau dynamic load tej yam kev mob nrog muaj zog kuj mus tas li deformation.

Tshuaj lom neeg thiab roj tsis kam: Zoo tiv taus ntau cov roj, roj, thiab tshuaj lom neeg.

Nrog rau kev ua tau zoo heev hauv kev siv lub zog, tawv, kub tsis kam, hydrolysis tsis kam, kev coj cwj pwm tsis zoo, qaug zog tsis kam, tshuaj lom neeg tsis kam, thiab roj tsis kam, NDI polyurethane tau siv dav hauv high{0}}kawg kev lag luam thiab engineering teb nrog cov khoom siv siab heev.
