Amandla aqinile: eyaziwa nangokuthi amandla aqinile. Kubhekiselwa kumandla adingekayo endaweni ngayinye ukuze irabha ifinyelele ubude obuthile, okungukuthi, ukuze ifinyelele ku-100%, 200%, 300%, 500%. Kuvezwe ngo-N/cm2. Lena inkomba ebalulekile yomshini yokulinganisa amandla nokuqina kwerabha. Uma likhulu inani layo, kuba ngcono ukuqina kwerabha, okubonisa ukuthi lolu hlobo lwenjoloba alujwayele ukuwohloka nokunwebeka.
Ukumelana nezinyembezi: Uma imikhiqizo yenjoloba ineminkenke ngesikhathi isetshenziswa, izodabula kakhudlwana futhi ekugcineni ilahlwe. Ngakho ukumelana nezinyembezi kuyinkomba ebalulekile yokusebenza kwemishini emikhiqizweni yenjoloba. Ukumelana nezinyembezi ngokuvamile kukalwa ngevelu yokumelana nezinyembezi, okubhekisela kumandla adingekayo ngogqinsi lweyunithi ngayinye (cm) yerabha ukuze kudabuke lapho isika ize inqamuke, ikalwa ngo-N/cm. Yiqiniso, inani elikhulu, lingcono.
Ukunamathela namandla okunamathela: Amandla adingekayo ukuze kuhlukaniswe izindawo ezimbili ezibophezelayo zemikhiqizo yenjoloba (njengeglue nendwangu noma indwangu nendwangu) ibizwa ngokuthi ukunamathela. Ubukhulu bokunamathela ngokuvamile bulinganiswa ngamandla okunamathela, aboniswa njengamandla angaphandle adingekayo endaweni ngayinye yeyunithi lapho izindawo ezimbili ezihlangene zesampula zihlukaniswa. Iyunithi yokubala ngu-N/cm noma N/2.5cm. Amandla okunamathelayo ayinkomba ebalulekile yokusebenza komshini emikhiqizweni yenjoloba eyenziwe ngokotini noma ezinye izindwangu zefiber njengezinto zohlaka lwamathambo, futhi-ke, uma likhulu inani, liba ngcono.
Ukulahlekelwa kwezingubo: eyaziwa nangokuthi ukunciphisa okuthile kokugqokwa, iyinkomba yekhwalithi eyinhloko yokulinganisa ukumelana nokugqokwa kwezinto zenjoloba, futhi kunezindlela eziningi zokukala nokuyiveza. Njengamanje, i-China isebenzisa kakhulu indlela yokuhlola i-Akron abrasion, ehlanganisa ukungqubuzana phakathi kwesondo lenjoloba kanye nesondo lokugaya eliqinile (Shore 780) ngaphansi kwe-engeli ethile yokuthamba (150) nomthwalo othile (2.72kg) ukuze kunqunywe ukuguga. inani lerabha phakathi kokushaywa okuthile (1.61km), elivezwe ngo-cm3/1.61km. Uma kuncane lokhu kubaluleka, kungcono ukumelana nokugqoka kwerabha.
Izinga lokushisa elibi kanye nezinga lokushisa lokushintsha kwengilazi: Lezi yizinkomba zekhwalithi zokunquma ukumelana okubandayo kwerabha. Irabha izoqala ukuqina ngaphansi kwezinga-degree Celsius lapho ingenisiwe, inciphisa kakhulu ukunwebeka kwayo; Njengoba izinga lokushisa liqhubeka lincipha, kancane kancane liyaqina kuze kube seqophelweni lapho ukunwebeka kwalo kuncipha khona ngokuphelele, njengengilazi eshwabene futhi eqinile, futhi ekwazi ukuphahlazeka lapho ishaya. Lokhu kushisa kubizwa ngokuthi izinga lokushisa lokushintsha kwengilazi, okuyizinga lokushisa eliphansi kakhulu lokusebenza kwerabha. Embonini, izinga lokushisa lokushintsha kwengilazi ngokuvamile alilinganiswa (ngenxa yesikhathi eside), kodwa izinga lokushisa elibi liyalinganiswa. Izinga lokushisa irabha eqala ngalo ukuphuka ngemva kokuba iqhwa emazingeni okushisa aphansi isikhathi esithile futhi ibe ngaphansi kwamandla athile angaphandle libizwa ngokuthi izinga lokushisa elinqamukayo. Izinga lokushisa le-brittle livame ukuba phezulu kunezinga lokushisa lokushintsha kwengilazi, futhi lapho izinga lokushisa liphansi, kuba ngcono ukumelana nokubanda kwale rabha.
Izinga lokushisa lokuqhekeka: Ngemva kokuba irabha ishiselwe ekushiseni okuthile, i-colloid izoqhekeka, futhi lokhu kushisa kubizwa ngokuthi izinga lokushisa lokuqhekeka. Lesi inkomba yokusebenza yokulinganisa ukumelana nokushisa kwerabha. Ukuphakama kwezinga lokushisa lokuqhekeka, kungcono ukumelana nokushisa kwale rabha. Izinga lokushisa langempela lokusebenza kwerabha evamile liphakathi kwezinga lokushisa eliphukile kanye nezinga lokushisa eliqhekezayo.
Impahla yokulwa nokuvuvukala: Eminye imikhiqizo yenjoloba ivamise ukuthintana nezinto ezifana ne-asidi, i-alkali, uwoyela, njll. ngesikhathi sokusetshenziswa, okubangela ukuthi imikhiqizo yenjoloba yande, ingaphezulu linamathele, futhi ekugcineni imikhiqizo ichithwe. Ukusebenza kwemikhiqizo yenjoloba ekumelaneni nemiphumela ye-asidi, i-alkali, uwoyela, njll. kubizwa ngokuthi i-anti swelling. Kunezindlela ezimbili zokulinganisa ukumelana nokuvuvukala kwenjoloba: enye iwukucwilisa isampula yenjoloba endaweni ewuketshezi efana ne-asidi, i-alkali, uwoyela, njll., futhi ngemva kwezinga lokushisa elithile nesikhathi, linganisa isisindo sayo (noma ivolumu) ukunwetshwa. isilinganiso; Uma lincane inani layo, kuba ngcono ukumelana kwerabha ekuvuvukeni. Enye indlela ukuyiveza ngesilinganiso samandla aqinile ngemva kokucwiliswa emandleni aqinile ngaphambi kokucwiliswa, okubizwa ngokuthi ukumelana ne-asidi (alkali) noma i-coefficient yokumelana nowoyela; Uma le coefficient inkulu, iba ngcono ukumelana nerabha ekuvuvukeni.
I-coefficient yokuguga: I-coefficient yokuguga iyinkomba yokusebenza ekala ukumelana nokuguga kwerabha. Ivezwa njengesilinganiso sezakhiwo zomzimba nezomshini (amandla aqinile noma umkhiqizo wamandla aqinile kanye nokwelula) werabha ngemva kokuguga ezingeni lokushisa elithile nangesikhathi esithile. I-coefficient yokuguga ephezulu ibonisa ukumelana okuhle nokuguga kwale rabha.
