Isondo elinegwebu elenziwe ngezinto zepulasitiki ezinegwebu, ezinokuqina kosayizi, izinga lokushintsha <1%.Futhi ukuqina kwamakhemikhali, i-anti-corrosion kanye ne-anti-aging, ikakhulukazi ikhono lesixazululo se-organic, i-asidi eqinile, izici ezibuthakathaka ze-alkali corrosion.Isondo elinegwebu elenziwe ngepulasitiki elinegwebu linezici zesisindo esilula, okonga impahla, ukumunca umthwalo womthelela, ukufakwa kokushisa nokufakwa komsindo kanye namandla aphezulu ngenxa yokuba khona kwamabhamuza.
Amathayi anegwebu akudingeki akhathazeke ngamathayi abhobokile, akudingeki ukuthi ampompe.Isondo eliphefumulayo, elaziwa nangokuthi isondo elingenalutho, libhekisela emgodini ongaphakathi wesondo odinga ukugcwaliswa ngegesi elicindezelwe, futhi lingakwazi ukugcina ukucindezela kwangaphakathi.Kunamathayi amashubhu namathayi angenamashubhu.Lolu hlobo lwesondo lusebenza kahle futhi ludambisa amandla futhi lukwazi ukumelana nokugoqeka okuphansi ngoba ingaphakathi ligcwele igesi noma uketshezi.
I-Pu Foam tire compound series, izici zayo yilezi: azinabuthi, azinambitheki, azishisi, inqubo yensimu yomsindo elula, ikhwalithi yomkhiqizo ozinzile, kulula ukuyiqonda;
Isisindo samathayi akhiqizwa yi-1/2 yamathayi enjoloba;
Ukumelana nokugqoka izikhathi ezingu-6 zamathayi enjoloba;
Izinga lokugoba liphindwe izikhathi ezi-5 kunelo lamasondo enjoloba;
Igcina ukunwebeka kwayo ku-minus 50 degrees,
Ukumelana ne-Acid ne-alkali, ukumelana nokugqwala izikhathi ezingu-3.5 zamasondo enjoloba;
I-Elasticity iphakeme izikhathi ezi-3 kunamathayi enjoloba;
Kungenziwa ngokwezifiso ngokusho kokuqina, ukuminyana, imininingwane yazo zonke izinhlobo zamasondo.
Umehluko wesondo le-Pu nesondo lerabha
● Imvelo ehlukile
◆ Isondo lenjoloba: Isondo lenjoloba lisezimotweni ezihlukahlukene noma emishinini ehlanganiswe phansi egingqika eyindilinga eyimikhiqizo yamasondo erabha enwebekayo.
◆ Isondo le-PU: isondo le-pu.
● Izici ezihlukene
1. Izici zesondo lenjoloba:
(1) Lapho kwakhiwa imikhiqizo yenjoloba, ukuhlangana kwama-elastomers akukwazi ukuqedwa ngemva kokucindezela okukhulu.Lapho umkhiqizo wenjoloba uhlukaniswa nesikhunta, ukuncipha kwe-elastomer akuzinzile kakhulu (ukuncipha kwerabha kuyahlukahluka kuye ngohlobo lwenjoloba).I-elastomer kufanele ihlale kancane ngokuhamba kwesikhathi.
Ngakho-ke, ekuqaleni komklamo womkhiqizo wenjoloba, kokubili ifomula kanye nesikhunta, kufanele ubale ngokucophelela izinga lokuxhumanisa.Uma kungenjalo, usayizi womkhiqizo ngeke uzinze, ikhwalithi yomkhiqizo izoba phansi kakhulu.
(2) Irabha i-thermosetting elastomer, futhi ipulasitiki i-thermosetting elastomer.Izinga lokushisa lokubumba iraba nokuvuvukala liyahlukahluka kuye ngohlobo oluyinhloko lwe-sulfide futhi lingase lithintwe ukushintsha kwesimo sezulu kanye nezinga lokushisa lasendlini kanye nomswakama.Ngakho-ke, izimo zokukhiqiza zemikhiqizo yenjoloba zidinga ukulungiswa nganoma yisiphi isikhathi.Uma kungenjalo, kungase kube khona umehluko ngekhwalithi yomkhiqizo.
2. Izici zamasondo e-PU: i-elastic ingadlala umphumela othile wokudambisa (ngisho nangaphezu kwesondo eliphefumulayo), ukubamba okuhle, akulula ukushelela, ukumelana nokugqoka okwengeziwe, ukusebenza ngokunethezeka kuhle.
