Paub meej
► Hydrogenated nitrile roj hmab (HNBR) thiab nitrile roj hmab (NBR) yog ob hom khoom siv roj hmab thermoplastic. Ntxiv nrog rau lawv cov khoom sib txawv ntawm lub cev, muaj ntau qhov sib txawv. Hauv tsab xov xwm no, peb yuav qhia cov ntsiab lus ntawm hydrogenated nitrile roj hmab thiab nitrile roj hmab, nrog rau qhov sib txawv ntawm ob.
► Ua ntej, peb yuav tsum piav qhia txog cov ntsiab cai ntawm ob. Qhov no yog vim hydrogenated nitrile roj hmab thiab nitrile roj hmab yog ob qho tib si tshuaj kho cov roj hmab, Ameslikas los ntawm polyvinyl chloride (PVC). Hydrogenated nitrile roj hmab (HNBR) yog cov khoom siv tshiab tau los ntawm hydrogenating PVC. Nws cov yam ntxwv yog tias nws muaj hydrogen daim ntawv cog lus ntawm cov saw hlau molecular, uas ua rau nws muaj zog dua kub thiab tensile zog, yog li nws muaj qhov kub thiab txias dua li cov roj hmab ntshiab nitrile. Nitrile roj hmab (NBR) yog ib yam khoom tau los ntawm alkyd hloov kho ntawm polyethylene. Piv nrog hydrogenated nitrile roj hmab, nws muaj cov roj zoo dua thiab cov tshuaj tsis haum.
► Qhov txawv ntawm HNBR thiab NBR yog tias hydrogenated nitrile roj hmab muaj qhov kub thiab txias ntau dua li cov roj hmab nitrile, thiab nws tuaj yeem tiv taus qhov kub thiab txias, tab sis cov roj hmab nitrile muaj kev ua tau zoo dua thiab tuaj yeem hloov kho kom lub cev muaj zog. Hydrogenated nitrile roj hmab yog tiag tiag hydrogenated raw cov ntaub ntawv, tab sis nitrile roj hmab yog tau los ntawm alkyd hloov. Yog li ntawd, lub zog tensile ntawm hydrogenated nitrile roj hmab yog siab dua li ntawm nitrile roj hmab.
► Hydrogenated nitrile roj hmab kuj muaj tensile tsis kam thiab thermal stability, thaum nitrile roj hmab pom zoo roj kuj thiab tshuaj tsis kam. Txawm li cas los xij, vim tias hydrogenated nitrile roj hmab thiab nitrile roj hmab yog ob qho tib si hloov kho cov roj hmab, kuj tseem muaj qee qhov sib txawv hauv lawv lub cev, suav nrog qhov ntsuas kub tsis kam, elastic modulus, tensile zog thiab hnav tsis kam. Lub tshav kub tsis kam ntawm hydrogenated nitrile roj hmab yog zoo dua li ntawm nitrile roj hmab. Nws qhov ntsuas kub tsis kam tuaj yeem ncav cuag siab tshaj 150 degree, thaum qhov ntsuas kub ntawm nitrile roj hmab tuaj yeem ncav cuag li 120 degree. Tsis tas li ntawd, lub zog tensile ntawm hydrogenated nitrile roj hmab kuj siab dua li ntawm nitrile roj hmab. Nws lub zog tensile nyob nruab nrab ntawm 25-32MPa, thaum lub zog tensile ntawm nitrile roj hmab feem ntau tsuas yog 7-8MPa.
► Tsis tas li ntawd xwb, hydrogenated nitrile roj hmab thiab nitrile roj hmab kuj muaj qhov sib txawv hauv daim ntawv thov. Hydrogenated nitrile roj hmab feem ntau yog siv nyob rau hauv qhov kub thiab txias ib puag ncig xws li tsheb, electronics, hydraulics thiab cov twj paj nruag, thaum nitrile roj hmab yog ntau haum rau petrochemical industries xws li lubricants, inks, oily coatings, roj av thiab diesel.
