Imbaraga: bizwi kandi nkimbaraga zingutu. Yerekeza ku mbaraga zisabwa kuri buri gice kugirango reberi irambure ku burebure runaka, ni ukuvuga kuramba kugeza 100%, 200%, 300%, 500%. Byerekanwe muri N / cm2. Iki nikimenyetso cyingenzi cyo gupima imbaraga nubukomezi bwa reberi. Nini agaciro kayo, niko reberi ishobora kwihanganira, byerekana ko ubu bwoko bwa reberi budakunda guhindagurika.
Kurira amarira: Niba ibicuruzwa bya reberi bifite ibice mugihe cyo kubikoresha, bizashwanyagurika cyane hanyuma biveho. Kurwanya amarira rero nikimenyetso cyingenzi cyerekana imikorere yibikoresho bya reberi. Kurwanya amarira mubisanzwe bipimwa nigiciro cyo kurwanya amarira, bivuze imbaraga zisabwa kuri buri gice cyubugari (cm) cya reberi kugirango ushwanyagurike kugeza igihe kimenetse, gipimwa muri N / cm. Birumvikana, uko agaciro kangana, nibyiza.
Gukomera hamwe no gukomera: Imbaraga zisabwa gutandukanya ibice bibiri bihuza ibicuruzwa bya reberi (nka kole nigitambara cyangwa igitambaro nigitambara) byitwa adhesion. Ingano ya adhesion isanzwe ipimwa nimbaraga zifatika, zigaragazwa nkimbaraga zo hanze zisabwa kuri buri gace iyo ibice byombi bihuza icyitegererezo bitandukanijwe. Igice cyo kubara ni N / cm cyangwa N / 2.5cm. Imbaraga zifatika nigipimo cyingenzi cyerekana imikorere mubikoresho bya reberi bikozwe mu ipamba cyangwa ibindi bitambaro bya fibre nkibikoresho bya skeleton, kandi birumvikana ko uko agaciro kangana, ari byiza.
Kwambara igihombo: bizwi kandi nkigabanuka ryimyambarire, nicyo kintu nyamukuru cyerekana ubuziranenge bwo gupima imyambarire y’ibikoresho bya reberi, kandi hariho uburyo bwinshi bwo gupima no kubigaragaza. Kugeza ubu, Ubushinwa bukoresha uburyo bwo gupima Akron abrasion, burimo guterana hagati y’uruziga rwa reberi n’uruziga rusanzwe rusya (Shore 780) munsi y’uruhande runaka (150) n'umutwaro runaka (2.72kg) kugirango umenye imyambarire ingano ya reberi muri stroke imwe (1.61km), igaragara muri cm3 / 1.61km. Gutoya agaciro, niko kurwanya kwangirika kwa reberi.
Ubushyuhe buke nubushyuhe bwinzibacyuho: Ibi nibipimo byubuziranenge kugirango umenye ubukonje bwa reberi. Rubber izatangira gukomera munsi ya dogere selisiyusi iyo yinjiye, igabanye cyane ubukana bwayo; Mugihe ubushyuhe bukomeje kugabanuka, buhoro buhoro bikomera kugeza aho ubuhanga bwabwo butakara burundu, nkikirahure, cyoroshye kandi gikomeye, kandi gishobora kumeneka ku ngaruka. Ubu bushyuhe bwitwa ubushyuhe bwikirahure, nubushyuhe buke bwo gukora kuri rubber. Mu nganda, ubushyuhe bwikirahure mubusanzwe ntibupimwa (kubera igihe kirekire), ariko ubushyuhe buke bupimwa. Ubushyuhe reberi itangira gucika nyuma yo gukonjeshwa ubushyuhe buke mugihe runaka kandi bugakorerwa imbaraga runaka zo hanze byitwa ubushyuhe buke. Ubushyuhe buke busanzwe buri hejuru yubushyuhe bwikirahure, kandi nubushyuhe buke, niko kurwanya ubukonje bukabije.
Ubushyuhe bukabije: Rubber imaze gushyuha mubushyuhe runaka, colloid izacika, kandi ubu bushyuhe bwitwa ubushyuhe bwo guturika. Iki nikimenyetso cyerekana gupima ubushyuhe bwa reberi. Ubushyuhe buringaniye, niko birwanya ubushyuhe bwiyi reberi. Ubushuhe nyabwo bukora bwa reberi rusange iri hagati yubushyuhe buke nubushyuhe bukabije.
Kurwanya kubyimba. Imikorere y'ibicuruzwa bya reberi mukurwanya ingaruka za aside, alkali, amavuta, nibindi byitwa kurwanya kubyimba. Hariho uburyo bubiri bwo gupima ubukana bwa reberi: bumwe nugushira icyitegererezo cya reberi muburyo bwamazi nka aside, alkali, amavuta, nibindi, hanyuma nyuma yubushyuhe nigihe runaka, bapima uburemere bwacyo (cyangwa ingano) igipimo; Agaciro kayo gake, niko reberi irwanya kubyimba. Ubundi buryo ni ukugaragaza ku kigereranyo cyimbaraga zingana nyuma yo kwibizwa hamwe nimbaraga zingana mbere yo kwibizwa, aribyo bita aside irike (alkali) cyangwa coefficient de coiffe; Iyo coefficient nini, niko reberi irwanya kubyimba.
Coefficient yo gusaza: Coefficient yo gusaza nikimenyetso cyerekana imikorere igereranya gusaza kwa reberi. Byerekanwa nkigipimo cyimiterere yumubiri nubukanishi (imbaraga zingana cyangwa umusaruro wimbaraga zingana no kuramba) ya reberi nyuma yo gusaza mubushyuhe runaka kandi mugihe runaka. Coefficient yo gusaza cyane yerekana gusaza neza kurubu.
