Kuvanga reberi ni ugukwirakwiza ibice bitandukanye kuri reberi hamwe nubufasha bwingufu za reberi za reberi, kugirango ubone ibikoresho bya reberi hamwe na reberi, hamwe nibikoresho bihuye na reberi, hamwe na powder, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, pigment, n'ibindi) nk'icyiciro cyatatanye. inzira. Ibisabwa byihariye bya tekiniki byimikorere yuzuye ni: Gutandukana rimwe na kimwe cyo guterana kwabakozi, cyane cyane umukira wihuta nka karubone, bigerwaho kugirango imikorere ihamye ya rubber. Rubber yavuyemo yitwa 'Yoko Rubber ' kandi ireme ryayo ifite imbaraga zingenzi kubindi bikorwa no gutanga umusaruro.

1 - kwiyongera kwa neoprene

        Neoprene ni uburyo bwa emulsion uburyo bwo gutanga umusaruro, inzira yo gukora ahanini ni ingaragu mugihe gito cyane. Ubushyuhe bwinyamanswa bugenzurwa ahanini kuri 40-60 ℃, kandi igipimo cyo guhinduka ni 90%. Ubushyuhe bukabije, igipimo cyanyuma cyo guhinduka ni inzira ndende cyangwa ifite ubunini mu kirere izatera kugabanuka mubwiza bwibicuruzwa. Ubwinshi bwa molekolar bugengwa na sulfur-kiram (tetraalkylamiomiomirlamidefide) imikorere. Ibibi nyamukuru bya sisitemu ya sulfur-kiuram nukubura umutekano wa sulfuru, niyihe mpamvu zingenzi zitera imitungo yo kubika. Niba ubwinshi bwa molecular bwahinduwe na Thiol burashobora kunoza iyi mikorere. Neoprene aratandukanye na reberi rusange ya synthique, ntabwo ikoresha sulfuro ibiganiro, ariko hamwe na zinc okide, magnesium oxide, nibindi.

Imikorere itunganya ya neoprene biterwa nimyitwarire ya vinosike ya reberi idahuye, hamwe nimyitwarire yayo ya visoe ifitanye isano nuburyo butandukanye nubushyuhe. Mugihe kuvanga muri rusange bikorwa muri leta ya elastike kugirango ukoreshe imbaraga zububiko bwa relasiti ya reberi kugirango usimbure neza. Kubwibyo, kugirango wirinde imbaraga zubushyuhe bwo hejuru mugihe uvanze neoprene, filler igomba kongerwaho hakiri kare bishoboka kugirango ugere ku rwego runaka rwo kuvanga muri leta ya elastike. Iyo uvanze ufunguye ufunguye, G-Ubwoko bwa NEPREE bumva imikino yubushyuhe, kandi ubushyuhe burenze 70 ℃, ni muri leta igendanwa, kandi yuzuye ntabwo byoroshye gutatanya. Iyo uvanze hamwe no gutunga cyane, ubushobozi bwayo bugomba kugabanuka neza, ibintu bisanzwe byuzuza 0.6 birakwiye, muri rusange bigabanywamo kuvanga bibiri, kugirango ugabanye ubushyuhe buvanze. Ubushyuhe bwo gusohora bugomba kuba burenze 100 ℃.

Neoprene mugukoresha imashini ifunguye Imashini irangwa nibibi ni nini, byoroshye gukomera ku muzingo, bityo ubushyuhe bwihuta butagomba kuba buto, ubushobozi bwihuta ntibukwiye kuba bunini. Kubera ubushishozi bukomeye kubushyuhe, intego-rusange neoprene mubushyuhe bwicyumba kugera kuri 71 ℃, muri iki gihe, ubworoherane bwa reberi mbisi, ntabwo ari umuvuduko ukomeye wa rubber, ntabwo ari umuzingo ukomeye gusa, kandi ugabana kandi abakozi nabo bazagorana cyane. Ubushyuhe bwa leta ya elastike bwa neoprene buteganijwe buri munsi ya 79 ℃, bityo rero imikorere yo kuvanga iruta sulfure, niko bigenda bikururwa, kandi impengamiro yo kuzunguruka no guswera ni nto. Kanda hamwe na mashini ifunguye, kugirango wirinde umuzingo uhamye, ubushyuhe bwumuzingo muri rusange bugenzurwa na 40 ~ 50 ℃ cyangwa muri reberi yimbere igacanwa. Iyo uvanze, ubanza ongeraho aside assorbent magnesium oxide kugirango wirinde guswera, hanyuma wongere ongeraho kinc okiside. Kugirango ugabanye ubushyuhe bwo kuvanga, Carbone Umukara na Softeners zongeweho zirashobora kongerwaho muburyo bundi. Acide acide hamwe na paraffin ibishashara nibindi bikorwa byateganijwe birashobora gutatanwa buhoro buhoro, kugirango bifashe gutatanya, ahubwo no gukumira abambuzi bakomeye. Sulfure-yagenzuye Chloroprepre ya Audiner kuvara ni 30% kugeza kuri 50% kurenza reberi karemano, igihe kitari sulfure kirashobora kuba inshuro zigufi zirenze kuri sulfure. Kugirango wirinde guswera mumashini yo kuvanga mu gufungura ubushyuhe bugenda bwihuta cyane, igipimo cyihuta kiri munsi ya 1: 1.2 hepfo, ingaruka zo gukonjesha zizaba nziza. Kugabanya ubushobozi bwo gutunganya nuburyo bwo kugenzura umutekano nibikorwa byiza. Kugeza ubu, sulfure yo mu gihugu yagenzuwe mu gihugu, itunganijwe neza kunono ubushobozi bwa reberi karemano bigomba kuba munsi ya 20% kugeza 30%, kugirango dukore bisanzwe. Nkuko inzoga ziroroshye guswera, kuburyo mugukoresha imashini yuzuye imashini isanzwe ikoreshwa muburyo bubiri bwo kuvanga. Ubushyuhe bwo kuvanga bugomba kuba munsi (gusohora ubushyuhe muri rusange bugenzurwa buri munsi ya 100 ℃), ubushobozi bwo gupakira buke muri 0.50 ~ 0,50 yongeweho muri 0.50. Kubibazo ko chloroprepne reberi kuvanga byoroshye kandi bigoye gutatana, gutondekanya imirongo ibiri ya 'x ' bikaba bikunze kugabanya ibintu byambere bya rekontone muburyo bwo kuvanga.

2 - Guteranya Engylene Procokene Rubber

       REBYYERANE Propaylene Rubber nayo irashobora gutunganywa ibikoresho bisanzwe bya reberi, ariko kubera ko ingaruka zinyuranye za rebrow, zikaba banza ukoreshe uruzitiro rufunganye, ubanza ukoreshe urujya n'uruza rufunganye, hanyuma ukoreshe urujya n'uruza rudahwema hanyuma ugura urupapuro ruhoraho hanyuma ugura urupapuro rwo kuvanga. Kuzunguruka ubushyuhe bwumuzingo 50 ~ 60 ℃, nyuma yumuzabibu 60 ~ 70 ℃ birakwiye. EPDM RUBYURO KUGURISHA ITEGEKO RYA BIKURIKIRA: GUKURIKIRA RUPDO-1/2 Carbone Umukara-1/1 Carnusi Umukara-Zincc Oxide RECYYANE Propaylene Rubber ntabwo byoroshye guhindurwa mugihe uvanze, kandi uruganda rwatatanye, ariko imitungo yo kwivuza ni umukene. Ethylene-propylene reberi ivanze hamwe no gutondekanya neza, muri rusange ukoreshe umwanya muto kugirango bikomeze nyuma yumuzingo, hanyuma urore buhoro buhoro umwanya uhuza, ongeraho ubushyuhe hagati ya 60 ~ 70 ℃. Ubushyuhe bwo kuvanga 150 ~ 160 ℃, bushobora gufasha gutatanya kwuzuza no gukandamiza no kuzamura imitungo ya mashini. Ubushobozi bwo gupakira burashobora kuba 10% ~ 15% hejuru y'ibindi bikoresho bya rubber.

3- guteranya fluoroelastomer

      Fluorine Rubber Menny Grecosiya nisumbabyose, bikomeye, bikabije, guhagarika ubushyuhe, kuvanga rusange no gutunganya biragoye. Mugihe uvanze Fleorine Rwibber kumashini itunganijwe, intera ntoya ya roll, ubushobozi buke, kuzunguruka ubushyuhe kuri 50 ~ 60 ℃. Kuvanga biratangira, ubanza utume umuzingo ukonje, ongeraho reberi ntoya zirenga ku rubingo, hanyuma wongere agace ka Rubber Fleorine Rubber iragoye gukoresha imashini ivanze, ariko ubwoko bwo kwivanga bwa sisitemu yo kuvanga imashini birakomera, urashobora kuvanga reberi. Rubber ihamye igomba guhagarara kumasaha 24 mbere yo gukoreshwa, kandi igomba kunonosorwa mbere yo gukoresha kugirango ikore inoze ikwirakwizwe kandi itezimbere amazi no kwihagararaho.
