Namba wan samting i bagarapim wok bilong raba: tempereja bilong vulcanization
Tempereja bilong raba bilong raba em i as kondisen bilong vulcanization riaksen (kroslinkim riaksen) bilong raba, we i afektim stret vulcanisasen spit na kwaliti bilong raba prodak.Olsem olgeta kemikel riaksen, vulkenaisesen riaksen i go antap wantaim inkris bilong tempereja, na em i isi long kamapim moa low salfa kroslink i fomesen. low.}}Pedres blong vulcanization i jenerol aplikebol long van’t law blong hoff, hemia, blong evri 8~10 rise long tempereja (samting we i sem mak long wan pes presa blong stim presa), riaksen spid i samples dabol;O samting olsem haf blong riaksen taem.
Tupela, namba tu samting i afektim vulcanization proses bilong raba: vulcanization presa
Vulcanization presa bilong raba em i wanpela bikpela samting bilong lukim olsem jiometrik sais, straksel densiti na fisikel na mekanik samting bilong ol raba pat. Long wankain taim, em i ken mekim gut tu gutpela pes bilong ol hap i no gat ol samting i no stret na inapim ol siling rikwaemen bilong ol raba prodak{1}Ol bikpela wok i stap olsem:
(1) blong blokem ol bubble long proses blong moldem vulcanization blong miksim raba mo impruvum kompak blong ol prodak;
(2) blong provaedem paoa blong fulumap flo blong glu, blong glu i save fulumap ful mol hol insaed long taem we oli talem;
(3) kamapim gutpela pasin bilong pas gut long raba na ol klem (katen, etc.) na bending resistens bilong ol raba prodak;
(4) kamapim gut ol samting bilong bodi na ol samting bilong masin bilong ol samting bilong raba.
Seleksen bilong vulcanization presa i mas tingim olsem fomula bilong glu, straksa bilong mol, kain bilong vulcanization ikwipmen (plet vulcanizing masin, injeksen vulkenais masin, injeksen vulkenaising masin, vekim vulkenais masin, etc.), straksa bilong prodak mak na sampela narapela samting{1}} .
Ol jenerol prinsipol blong seleksen blong presa blong vulcanization:
(1) strong blong glu i smol, presa i mas jusum smol, hae hadnes joes;
(2) ol liklik samting i makim ol liklik samting i tikpela na ol i makim bikpela samting;
(3) prodak straksa i simpol blong jusum smol, strakja i kompleks blong jusum bigfala;
(4) ol samting bilong masin i nidim bikpela mak, ol i mas makim liklik mak;
(5) taem tempereja blong vulcanization i hae moa, presa i save smol moa; taim tempereja i go daun, presa i mas antap.
Namba tri samting we i afektem proses blong raba blong raba: taem blong vulcanization
Vulcanization time is closely related to the temperature of vulcanization, in the vulcanization process, the physical and mechanical properties of vulcanized rubber to reach or close to the best point, this℃of vulcanization is called positive vulcanization or the most suitable vulcanization.The vulcanization time required to achieve positive vulcanization at a certain temperature is called positive vulcanization time.When the rubber formula and vulcanization temperature is sua, taim bilong vulkenisasen i makim mak bilong vulcanization, ol narapela narapela sais na wol tiknes bilong ol raba prodak long rot bilong kontrolim taim bilong vulcanization long kontrolim mak bilong vulcanization, planti taim sais bilong ol bikpela o tikpela prodak, longpela taim i mas stap bilong vulcanization.
