Ibice byinshi ninganda zikoresha imashini ivanga reberi.Ikintu kinini kiranga ni uko ifite ubworoherane nubworoherane, kandi ikwiranye cyane cyane no kuvanga ibintu byinshi bya rubber, reberi ikomeye, reberi ya sponge, nibindi.
Iyo kuvanga nurusyo rufunguye, gahunda yo gukuramo ni ngombwa cyane.Mubihe bisanzwe, reberi mbisi ishyirwa mu cyuho cyo kuzenguruka ku mpera imwe y’uruziga, kandi intera izunguruka igenzurwa nka 2mm (fata urugero rwa reberi ya santimetero 14) hanyuma uzunguruke mu minota 5.Kole mbisi ikozwe muri firime yoroshye kandi idafite icyuho, izengurutswe ku rubaho rw'imbere, kandi hari umubare munini wa kole yegeranijwe kuri roller.Rubber yegeranijwe ihwanye na 1/4 cyumubare wuzuye wa reberi mbisi, hanyuma hongerwaho imiti igabanya ubukana hamwe na moteri yihuta, hanyuma reberi ikandagirwa inshuro nyinshi.Intego yibi ni ugukora antioxydeant na yihuta ikwirakwizwa kashe.Muri icyo gihe, iyongezwa rya mbere rya antioxydeant irashobora gukumira ibintu byo gusaza byubushyuhe bibaho mugihe cyo kuvanga ubushyuhe bwinshi.Kandi byihuta bimwe bigira plastike kumashanyarazi.Zinc oxyde yongeyeho.Iyo wongeyeho umukara wa karubone, umubare muto cyane ugomba kongerwaho mugitangira, kuko reberi mbisi zizava kumuzingo mugihe umukara wa karubone wongeyeho.Niba hari ikimenyetso icyo ari cyo cyose cyo kureka, hagarika kongeramo umukara wa karubone, hanyuma wongeremo umukara wa karubone nyuma ya reberi yizengurutse uruziga neza.Hariho inzira nyinshi zo kongeramo karubone.Ahanini harimo: 1. Ongeramo karubone umukara uburebure bwakazi bwa roller;2. Ongeramo karubone umukara hagati ya roller;3. Ongeraho hafi yumutwe umwe wa baffle.Njye mbona, uburyo bubiri bwa nyuma bwo kongeramo umukara wa karubone nibyiza, ni ukuvuga ko igice kimwe cya degumming cyakuwe kuri roller, kandi ntibishoboka gukuraho uruziga rwose.Ibikoresho bya reberi bimaze gukurwaho umuzingo, umukara wa karubone uhindurwamo byoroshye, kandi ntibyoroshye gutatanya nyuma yo kuzunguruka.Cyane cyane iyo gukata reberi ikomeye, sulfure ikanda muri flake, bikaba bigoye cyane kuyikwirakwiza.Ntabwo gutunganya cyangwa gutambuka neza bishobora guhindura "umufuka" wumuhondo uboneka muri firime.Muri make, mugihe wongeyeho karubone umukara, ongeramo bike kandi kenshi.Ntugafate ikibazo cyo gusuka karubone yose kuri roller.Icyiciro cyambere cyo kongeramo karubone nigihe cyihuta cyo "kurya".Ntukongereho koroshya iki gihe.Nyuma yo kongeramo kimwe cya kabiri cyumukara wa karubone, ongeramo kimwe cya kabiri cyoroshya, gishobora kwihutisha "kugaburira".Igice cya kabiri cyoroshya cyongewe hamwe na karubone isigaye.Muburyo bwo kongeramo ifu, intera iringaniye igomba koroherezwa buhoro buhoro kugirango reberi yashyizwemo muburyo bukwiye, kugirango ifu isanzwe yinjira muri reberi kandi ishobora kuvangwa na reberi kurwego ntarengwa.Kuri iki cyiciro, birabujijwe rwose guca icyuma, kugira ngo bitagira ingaruka ku bwiza bw’imvange.Mugihe cyoroshye cyane, karubone yumukara niyoroshya nabyo birashobora kongerwaho muburyo bwa paste.Acide Stearic ntigomba kongerwamo hakiri kare, biroroshye gutera kuzunguruka, nibyiza kuyongeramo mugihe hakiriho umukara wa karubone murizingo, kandi agent ya volcanizing nayo igomba kongerwaho mugihe cyanyuma.Ibikoresho bimwe na bimwe byongeweho nabyo byongewe mugihe hakiri umukara muto wa karubone kuri roller.Nka agent ya DCP.Niba umukara wa karubone wose uribwe, DCP izashyuha kandi ishongeshe mumazi, izagwa mumurongo.Muri ubu buryo, umubare wibikoresho bya volcanizing mubigo bizagabanuka.Nkigisubizo, ubwiza bwibikoresho bya reberi bigira ingaruka, kandi birashoboka ko byatera ibirunga bidatetse.Kubwibyo, umukozi wibirunga agomba kongerwaho mugihe gikwiye, bitewe nubwoko butandukanye.Nyuma yubwoko bwose bwibintu byongeweho byongeweho, birakenewe ko uhindukirira kugirango reberi ivanze neza.Mubisanzwe, hariho "ibyuma umunani", "imifuka ya mpandeshatu", "kuzunguruka", "utubuto duto" n'ubundi buryo bwo guhinduka.
“Icyuma umunani” gikata ibyuma kuri 45 ° inguni yerekeza ku cyerekezo kibangikanye, inshuro enye kuruhande.Kole isigaye ihindagurika 90 ° hanyuma yongerwaho kuri roller.Ikigamijwe ni uko ibikoresho bya reberi bizunguruka mu cyerekezo gihagaritse kandi gitambitse, bifasha kuvanga kimwe.“Umufuka wa mpandeshatu” ni umufuka wa pulasitike ukozwe muri mpandeshatu n'imbaraga za roller.“Kuzunguruka” ni ugukata icyuma ukoresheje ukuboko kumwe, kuzunguza ibikoresho bya reberi muri silinderi ukoresheje ukundi kuboko, hanyuma ukabishyira mu ruziga.Intego yibi ni ugukora reberi ivanze neza.Nyamara, "umufuka wa mpandeshatu" na "kuzunguruka" ntabwo bifasha gukwirakwiza ubushyuhe bwibikoresho bya reberi, byoroshye gutera inkongi y'umuriro, kandi bisaba akazi cyane, ubwo buryo rero bubiri ntibukwiye gushyigikirwa.Guhindura umwanya iminota 5 kugeza kuri 6.
Ibikoresho bya reberi bimaze gushonga, birakenewe kunanura ibimera.Imyitozo yerekanye ko ibice byoroheje byoroshye bigira uruhare runini mu gukwirakwiza imiti ikomatanya.Uburyo bworoshye cyane ni uguhindura intera ya mm 0.1-0,5 mm, shyira ibikoresho bya reberi muri roller, hanyuma ukareka bikagwa mumurongo wo kugaburira bisanzwe.Nyuma yo kugwa, hindura ibikoresho bya reberi kuri 90 ° kumurongo wo hejuru.Ibi bisubirwamo inshuro 5 kugeza kuri 6.Niba ubushyuhe bwibikoresho bya reberi ari hejuru cyane, hagarika inzira yoroheje, hanyuma utegereze ko reberi ikonja mbere yo kunanuka kugirango wirinde ko reberi idashya.
Nyuma yo gutambuka neza birangiye, humura intera ya 4-5mm.Mbere yuko ibikoresho bya reberi bishyirwa mu modoka, agace gato k'ibikoresho bya reberi barashwanyaguzwa bagashyirwa mu muzingo.Ikigamijwe ni ugukubita intera iringaniye, kugirango wirinde imashini ivanga reberi gukorerwa urugomo runini no kwangiza ibikoresho nyuma y’ibikoresho byinshi bya reberi bigaburiwe muri roller.Ibikoresho bya reberi bimaze gupakirwa mumodoka, bigomba kunyura mumuzingo umwe, hanyuma ukabizinga kumuzingo w'imbere, komeza ubihindure muminota 2 kugeza kuri 3, hanyuma bipakurure kandi ubikonje mugihe.Filime ifite uburebure bwa cm 80, ubugari bwa cm 40 na cm 0,4 z'ubugari.Uburyo bukonje burimo gukonjesha bisanzwe hamwe no gukonjesha amazi akonje, ukurikije uko buri gice kimeze.Muri icyo gihe, birakenewe kwirinda guhura hagati ya firime nubutaka, umucanga nundi mwanda, kugirango bitagira ingaruka kumiterere yikibumbano.
Muburyo bwo kuvanga, intera yo kuzunguruka igomba kugenzurwa cyane.Ubushyuhe bukenewe mu kuvanga reberi mbisi zitandukanye no kuvanga ibintu bitandukanye bikomereye biratandukanye, bityo ubushyuhe bwa roller bugomba gutozwa ukurikije ibihe byihariye.
Bamwe mu bakozi bavanga reberi bafite ibitekerezo bibiri bikurikira bikurikira: 1. Batekereza ko igihe kinini cyo kuvanga, niko ubuziranenge bwa reberi.Ntabwo aribyo mubikorwa, kubwimpamvu zasobanuwe haruguru.2. Byizerwa ko byihuse ingano ya kole yegeranijwe hejuru ya roller yongeweho, umuvuduko wo kuvanga uzihuta.Mubyukuri, niba nta kole yegeranijwe hagati yizingo cyangwa kole yegeranijwe ni nto cyane, ifu izahita ikanda mubice hanyuma igwe mumurongo wo kugaburira.Muri ubu buryo, usibye kugira ingaruka ku bwiza bwa reberi ivanze, tray yo kugaburira igomba kongera gusukurwa, kandi ifu yaguye ikongerwaho hagati yizingo, igasubirwamo inshuro nyinshi, ikongerera igihe kinini cyo kuvanga kandi ikongera imirimo ubukana.Birumvikana, niba kwirundanya kwa kole ari byinshi, kuvanga umuvuduko wifu bizatinda.Birashobora kugaragara ko kwirundanya kwinshi cyangwa bike cyane bidakwiriye kuvangwa.Kubwibyo, hagomba kubaho umubare runaka wa kole yegeranijwe hagati yizunguruka mugihe cyo kuvanga.Mugihe cyo guteka, kuruhande rumwe, ifu yinjizwa muri kole hakoreshejwe imbaraga za mashini.Nkigisubizo, igihe cyo kuvanga kigufi, ubukana bwumurimo buragabanuka, kandi ubwiza bwibikoresho bya reberi nibyiza.
