PMD Series Zro2 Composite Ceramic Slide Plate, Zro2 Ring, Faka

Inhlanganisela yedatha yeRaman enemiphumela yokuhlaziywa kwe-thermogravimetric (TGA) ifakazela ukuthi ukuxhumaniseka kwama-macromolecule e-organic ezindaweni ezakhiwe ngobumba kuyenzeka. Ukuhlaziywa kwemishini enamandla (i-DMA) kwenziwe kusuka ku-100 kuye ku- + 50 ° C; ukwengezwa kwe-ceramic kwandisa i-modulus yokugcina, ikakhulukazi yokugcwalisa okuguquliwe. Uma kuqhathaniswa ne-PP ne-thermoplastic vulcanizate (TPV), ukwanda okuphezulu okushisayo kubonakala ngemuva kokufakwa kwe-ceramic filler, umphumela wokwenziwa kwevolumu yamahhala ethe xaxa. I-modulus eqine yezinhlanganisela icishe ibe ngu-1.2 izikhathi ze-TPV emsulwa, ukwanda kobulukhuni obudalwe ngokusobala yi-ceramic. Izindawo eziqhekekile zibonisa ukuhlangana okubuthaka kwezinhlayiya zokugcwalisa ku-matrix. Kusampula equkethe ukugcwaliswa okuguquliwe i-deens tensile ihamba nge-matrix ye-polymer.

Inhlanganisela ye-ceramic iyakwazi ukumelana namazinga okushisa angaphezu kwama-2200 F ngokuphindaphindiwe ngaphandle kokuqhekeka ngenxa yokushaqeka okushisayo. Inhlanganisela inewebhu yezintambo zokuqinisa; kanye ne-matrix ebaluleke kakhulu kuwebhu ngemuva kwesinyathelo sokudubula. I-matrix yakhiwa kuyo yonke iwebhu ngokumithisa iwebhu nge-sol equkethe i-alumina futhi, kwezinye izimo, ama-oxide womhlaba angavamile, nokudubula okuhlanganisiwe ngemuva kokufakwa. Iwebhu ingaba i-orthogonal weave enezinhlangothi ezintathu yemicu yokuqinisa, lapho imicu iyi-alumina yesigaba sesikhashana. Le nhlanganisela empeleni ayinazinsimbi zeQembu I neQembu II nezinsimbi zenguquko zensimbi. Inhlanganisela ingasetshenziswa njengezitini noma ulwelwesi olukhanyisayo futhi ingasetshenziswa futhi njengesixhobo esivikela umzimba ngenxa yemvelo engasebenzi.
