Tensile strength: kwaziwa njengamandla okuqina. Ibhekisa kumandla afunekayo kwiyunithi nganye yendawo ukuze irabha yande ukuya kubude obuthile, oko kukuthi, ukunweba ukuya kwi-100%, 200%, 300%, 500%. Ibonakaliswe nge-N/cm2. Esi sisalathisi esibalulekileyo somatshini wokulinganisa amandla kunye nokuqina kwerabha. Ixabiso layo likhulu, ngcono ukuqina kwerabha, ebonisa ukuba olu hlobo lwerabha luncinci kakhulu kwi-deformation elastic.
Ukumelana neenyembezi: Ukuba iimveliso zerabha zineentanda ngexesha lokusetyenziswa, ziya kukrazuka ngakumbi kwaye ekugqibeleni zilahlwe. Ke ukuxhathisa ukukrazula kukwaluphawu olubalulekileyo lokusebenza koomatshini kwiimveliso zerabha. Ukuxhathisa kweenyembezi ngokuqhelekileyo kulinganiswa ngexabiso lokumelana nokukrazula, elibhekiselele kumandla afunekayo ngokweyunithi yobukhulu (cm) yerabha ukukrazula kwindawo enqunyulwe de yophuke, elinganiselwa ku-N/cm. Ngokuqinisekileyo, ixabiso elikhulu, lingcono.
Ukubambelela kunye namandla okubambelela: Amandla afunekayo ukwahlula imiphezulu emibini edityanisiweyo yeemveliso zerabha (ezifana neglu nelaphu okanye ilaphu nelaphu) kuthiwa ukuncamathela. Ubungakanani bokubambelela ngokuqhelekileyo bulinganiswa ngamandla okubambelela, okubonakaliswa njengamandla angaphandle afunekayo kwindawo yeyunithi xa iindawo ezimbini zokubopha isampuli zihlukaniswe. Iyunithi yokubala yi-N/cm okanye N/2.5cm. Amandla okuncamathelayo sisalathiso esibalulekileyo sokusebenza koomatshini kwiimveliso zerabha ezenziwe ngomqhaphu okanye amanye amalaphu efayibha njengezinto zamathambo, kwaye ke, okukhona likhulu ixabiso, lingcono.
Ukunxiba ilahleko: Kwakhona kwaziwa njengokunciphisa okuthile kokunxiba, isalathisi esiphambili somgangatho wokulinganisa ukunyanzeliswa kwezixhobo zerabha, kwaye kukho iindlela ezininzi zokulinganisa nokubonakalisa. Okwangoku, i-China isebenzisa kakhulu indlela yokuvavanya i-Akron abrasion, ebandakanya ukukhuhlana phakathi kwevili lerabha kunye nesondo eliqhelekileyo lokusila (i-Shore 780) phantsi kwe-angle yokuthambekela ethile (150) kunye nomthwalo othile (2.72kg) ukumisela ukuguga. ubungakanani berabha ngaphakathi kwestroke ethile (1.61km), echazwe kwi-cm3 / 1.61km. Incinci eli xabiso, ngcono ukuxhathisa ukunxiba kwerabha.
Ubushushu obuncinci kunye nobushushu bokutshintsha kweglasi: Ezi zizibonakaliso zekhwalithi zokumisela ukuxhathisa okubandayo kwerabha. I-Rubber iya kuqala ukuqina ngaphantsi kwe-zero degrees Celsius xa ifakwe, inciphisa kakhulu ukuqina kwayo; Njengoko iqondo lobushushu liqhubeka lincipha, ngokuthe ngcembe liya liqina ukusa kwinqanaba apho ukunwebeka kwalo kulahleka ngokupheleleyo, kanye njengeglasi, eshwabeneyo kwaye iqinile, kwaye inokuqhekeka xa ichaphazeleka. Obu bushushu bubizwa ngokuba bubushushu bokutshintsha kweglasi, elona qondo lobushushu lisezantsi lokusebenza kwirabha. Kumashishini, iqondo lokushisa lokutshintsha kweglasi alinakulinganiswa (ngenxa yexesha elide), kodwa ubushushu obunqabileyo bulinganiswa. Iqondo lobushushu apho irabha iqala ukwaphuka emva kokuba ikhenkcezekile kwiqondo lobushushu eliphantsi kangangexesha elithile kwaye iphantsi kwamandla athile angaphandle ibizwa ngokuba bubushushu obunqabileyo. Ubushushu be-brittle buhlala buphezulu kunobushushu benguqu yeglasi, kwaye ubushushu obusezantsi buba buthathaka, kokukhona ukuqina okubandayo kwale rabha.
Ukuqhekeka kobushushu: Emva kokuba i-rubber ishushu kwiqondo lokushisa elithile, i-colloid iya kuqhekeka, kwaye eli qondo lokushisa libizwa ngokuba yiqondo lokushisa. Esi sibonakaliso sokusebenza sokulinganisa ukuchasana nokushisa kwerabha. Ukuphakama kweqondo lokushisa eliqhekezayo, bhetele ukumelana nobushushu bale rubha. Umgangatho wokushisa wangempela wokusebenza werabha jikelele uphakathi kobushushu obunqabileyo kunye nobushushu obuqhekezayo.
Anti ukudumba impahla: Ezinye iimveliso zerabha zihlala zidibana nezinto ezifana ne-asidi, i-alkali, i-oyile, njl njl ngexesha lokusetyenziswa, okubangela ukuba iimveliso zerabha zande, umphezulu unamathele, kwaye ekugqibeleni iimveliso zichithwa. Ukusebenza kweemveliso zerabha ekuchaseni imiphumo ye-asidi, i-alkali, ioli, njl njl kubizwa ngokuba yi-anti swelling. Kukho iindlela ezimbini zokulinganisa ukuxhathisa ukudumba kwerabha: enye kukuntywilisela isampulu yerabha kwindawo engamanzi efana neasidi, ialkali, ioli, njalo njalo, kwaye emva kobushushu obuthile kunye nexesha, ukulinganisa ubunzima bayo (okanye umthamo) ukwandiswa. izinga; Incinci ixabiso layo, ngcono ukuchasana kwerabha ekudumbeni. Enye indlela yokuyibonakalisa ngomlinganiselo wamandla okuqina emva kokuntywiliselwa kumandla okuqina ngaphambi kokuntywiliselwa, okubizwa ngokuba yi-asidi (alkali) yokumelana okanye icoefficient yokumelana neoyile; Inkulu le coefficient, ingcono ukuxhathisa kwerabha ekudumbeni.
Ukuguga komlinganiso: I-coefficient yokuguga isalathiso sokusebenza esilinganisa ukumelana nokuguga kwerabha. Ivakaliswa njengomlinganiselo weempawu zomzimba kunye noomatshini (amandla okuqina okanye imveliso yamandla okuqina kunye nobude) berabha emva kokuguga kwiqondo lobushushu elithile kunye nexesha elithile. I-coefficient yokuguga ephezulu ibonisa ukumelana nokuguga kakuhle kwale rubha.
