Ibice byinshi nimpande zikoresha ibyuma bya rubber. Ikintu cyacyo kinini nuko gifite imbaraga nyinshi no kugendana, kandi birakwiriye cyane cyane kuvanga impinduka zisanzwe za reberi, reberi ikomeye, sponge reberi, nibindi.
Iyo uvanze nurusyo rufunguye, gahunda yo gufatanya ni ngombwa cyane. Mubihe bisanzwe, reberi mbisi ishyirwa mubyumba byumuzingo kuruhande rumwe rwibiziga byikanda, kandi intera ya roza igenzurwa na 2mm (gufata rubber mixers nkurugero) no kuzunguruka muminota 5. Imashini mbisi yashinzwe muri firime yoroshye kandi yuzuye, ipfunyitse kuri roller yimbere, kandi hariho umubare runaka wa kole yegeranijwe kuri roller. Ibara rya rubber ryeruye hafi 1/4 ryinshi rya reberi mbisi, hanyuma abakozi bageze mu za busa na rwihuta no kwihuta, kandi rubber irasakuza inshuro nyinshi. Intego yibi ni ugukora antioxidant no kwihutisha gutatana neza muri kole. Muri icyo gihe, wongeyeho antioxydant irashobora kubuza ibintu bidasanzwe bishaje bibaho mugihe cyikinyoni kinini cya rubber. Kandi abihuta bamwe bafite ingaruka zo gutondeka ku rubingo. Zinc oxide noneho yongeyeho. Mugihe wongeyeho karubone umukara, amafaranga make cyane agomba kongerwaho mugitangira, kuko reberi zimwe mbi mbisi zizava kumuzingo zikimara kwirabura zikimara. Niba hari ikimenyetso icyo aricyo cyose, ureke kongeramo karubone, hanyuma wongere carbon umukara nyuma ya reberi izengurutse uruziga. Hariho inzira nyinshi zo kongeramo karubone. Aharya: 1. Ongeraho karubone umukara ku burebure bwakazi bwa roller; 2. Ongeraho karubone umukara hagati ya roller; 3. Ongeraho hafi yimpera imwe ya baffle. Njye mbona, uburyo bubiri bwo kongeramo karubone burashya, ni ukuvuga igice cya stamming cyakuwe muri roller, kandi ntibishoboka gukuraho roller yose. Nyuma yikigo cya rubber cyakuwe kumuzingo, karubone irarakara byoroshye muri flake, kandi ntabwo byoroshye gutatanya nyuma yo kuzukwa. Cyane cyane iyo ugabanye reberi ikomeye, sulfuru yakandagiye muri flake, bigora cyane gutatanya muri reberi. Ntabwo ushimangira cyangwa impinana yoroheje birashobora guhindura ahantu "umufuka" wumuhondo ubaho muri firime. Muri make, mugihe wongeyeho karubone umukara, ongeraho bike kandi kenshi. Ntugafate ikibazo cyo gusuka karubone yose umukara kuri roller. Icyiciro cyambere cyo kongeramo karubone umukara nigihe cyihuta cyo "kurya". Ntukongere kwiyongera muriki gihe. Nyuma yo kongeramo kimwe cya kabiri cya karubone umukara, ongeramo kimwe cya kabiri cyumutungo, ushobora kwihutisha "kugaburira". Ikindi gice cya Softener cyongeweho karubone isigaye. Muburyo bwo kongera ifu, intera ya roza igomba kuruhuka buhoro buhoro kugirango ikomeze kwinjizamo urwego rukwiye, kugirango ifu isanzwe yinjira muri reberi kandi irashobora kuvangwa na rubber kurwego ntarengwa. Kuri iki cyiciro, bibujijwe rwose guca icyuma, kugirango tutagira ingaruka kumiterere ya reberi. Kubijyanye na softener cyane, karubone irarabura kandi yoroshye irashobora kandi kongerwaho muburyo bwa paste. Acide yijimye ntigomba kongerwaho hakiri kare, biroroshye gutera imizingo, nibyiza kongeramo mugihe haracyari umukara wa karubone mumuzingo, kandi umukozi usubiramo nayo agomba kongerwa mugice cya nyuma. Abakozi bamwe bateye inkunga nabo bongeyeho mugihe hakiri kare ya karubone gato kuri roller. Nko gutera inkunga DCP. Niba karubone yose arira, DCP izashyuha kandi ishonga mumazi, azagwa muri tray. Muri ubu buryo, umubare w'abakozi ba tulcanie mu kigo uzagabanuka. Nkigisubizo, ireme ryibigo bya rubber bigira ingaruka, kandi birashoboka ko guterana ibibazo bidasekeje. Kubwibyo, umukozi wa Gusubiramo agomba kongerwaho mugihe gikwiye, bitewe nuburyo butandukanye. Nyuma yubwoko bwose bwibibazo byongeweho byongeyeho, birakenewe kurushaho guhindukira kugirango rubbende zivange neza. Mubisanzwe, hariho "ibyuma umunani", "imifuka umunani", "kuzunguruka", "igiti cyoroshye" n'ubundi buryo bwo guhinduka.
"Ibyuma umunani" zirimo gukata ibyuma ku mfuruka 45 ° ku cyerekezo kibangikanye cya roller, inshuro enye ku mpande. Glue isigaye igoretse 90 ° hanyuma yongewe kuri roller. Intego nuko ibikoresho bya reberi bizunguruka mubyerekezo bihagaritse kandi bitambitse, bifasha kuvanga imyenda imwe. "Agasanduku k'inyabutatu" ni umufuka wa pulasitike ukozwe muri mpandeshatu n'imbaraga za roller. "Kuzunguruka" ni ugukata ukuboko kumwe, kuzunguruka ibikoresho bya reberi muri silinderi ukoresheje urundi ruhande, hanyuma ubishyire muri roller. Intego yibi ni ugukora reberi ivanze. Ariko, "Umufuka wa mpandeshatu" na "kuzunguruka" ntabwo bifasha gutandukanya ubushyuhe bwibikoresho bya rubber, biroroshye gutera scorch, kandi biroroshye gutuma, bityo rero, ubwo buryo butunganye ntibukwiye kugirirwa neza. Guhindura umwanya iminota 5 kugeza kuri 6.
Nyuma yikigo cya rubber gishonga, ni ngombwa koroheje. Imyitozo yagaragaje ko uruganda ruto rufite akamaro cyane mugutatanya umukozi ushingiye ku gaciro. Uburyo bworoshye-pass nuguhindura intera ya roller kugeza 0.1-0.5, shyira ibikoresho bya reberi muri roller, hanyuma ureke bigwe munzira yo kugaburira bisanzwe. Nyuma yo kugwa, hindura ibikoresho bya reberi kuri 90 ° kuri roller yo hejuru. Ibi bisubirwamo inshuro 5 kugeza kuri 6. Niba ubushyuhe bwibikoresho bya rubber ari hejuru cyane, hagarika pasiporo yoroheje, hanyuma utegereze ibikoresho bya rubber kugirango bikonje mbere yo guhagarika ibikoresho bya reberi.
Nyuma yicyiciro cyoroheje kirangiye, humura intera ya 4-5mm. Mbere y'ibikoresho bya rubber bipakiwe mu modoka, agace gato k'ibikoresho bya rubber byashwanyaguritse hanyuma ugashyirwa mu ruzingo. Intego ni ugukubita intera ya roza, kugirango wirinde imashini ivanga ya rubber ikorerwa imbaraga kandi yangiza ibikoresho nyuma yuburyo bunini bwa reberi bugaburirwa. Nyuma yibikoresho bya rubber biremerewe kumodoka, bigomba kunyura mu cyuho rimwe, hanyuma uyizingire ku muzingo w'imbere, komeza ubihindure mu minota 2 kugeza kuri 3, hanyuma ukurure kandi ukonjere mugihe. Filime ni cm 80 z'uburebure, cm 40 z'ubugari na 0.4 cm. Uburyo bukonje burimo gukonjesha nubukonje bwa tank yo gukonjesha, bitewe nibisabwa na buri gice. Mugihe kimwe, ni ngombwa kwirinda guhura hagati ya firime nubutaka, umucanga nundi mwanda, kugirango tutagira ingaruka kumiterere ya reberi.
Muburyo bwo kuvanga, intera ya roza igomba kugenzurwa neza. Ubushyuhe bukenewe kugirango uvange bwa reberi zitandukanye mbisi hamwe no kuvanga ibice bitandukanye bikomeye biratandukanye, bityo ubushyuhe bwa roller bugomba gumenyekana ukurikije imiterere yihariye.
Abakozi ba rubber bavanze ba rubber bafite ibitekerezo bibiri bikurikira: 1. Batekereza ko igihe kirekire cyo kuvanga, ubwiza bwa reberi. Ntabwo aribyo mubikorwa, kubwimpamvu zasobanuwe haruguru. 2. Bikekwa ko byihuse umubare wa kole wegeranijwe hejuru yumuzingo wongeyeho, byihuse umuvuduko uvanga. Mubyukuri, niba nta bikoresho bikusanyije hagati yumurongo cyangwa kongurujwe hejuru cyane, ifu izandarikana byoroshye mugukubita no kugwa muburyo bwo kugaburira. Muri ubu buryo, usibye kwibasira ubwiza bwa reberi ivanze, kugaburira byongeye gusukurwa, kandi ifu yaguye yongewe hagati y'abazimizinyi, yongera inshuro nyinshi igihe cyo kuvanga kandi yongera imbaraga z'abakozi. Birumvikana, niba gukusanya kole ari byinshi, umuvuduko uvanga wifu uzatinda. Birashobora kugaragara ko byinshi cyangwa bike byo gukusanya kole bidashobora kuvanga. Kubwibyo, hagomba kubaho umubare runaka wa kole yegeranijwe hagati yumuzingo mugihe cyo kuvanga. Mugihe cyo guteka, kuruhande rumwe, ifu iranyuzwa muri kole nigikorwa cyingufu zamashini. Kubera iyo mpamvu, igihe cyo kuvanga kigufi, ubukana bwakazi buragabanuka, kandi ubwiza bwikigo cya rubber ni cyiza.
