Uburyo butatu bw'ibanze mu gihe cyo kuvanga rubber ukoresheje imashini ivanga rubber

Imashini ivanga ikoresheje rabha igizwe n'ibikorwa bitatu mu kuvanga rabha: Gupfunyika, Guteka ifu, Gutunganya no gutunganya.

1. Gupfunyika umuzingo

Mu gihe cyo kuvanga, hashobora kubaho ibihe bine bishoboka aho irabu mbisi igaragara ku irangi ry'urusyo rufunguye

Ikibazo cya mbere kibaho iyo ubushyuhe bw'umuzingo buri hasi cyane cyangwa umuzingo ukomeye, bigatuma umuzingo uguma kuri umuzingo wakusanyijwe n'umuzingo, ntushobore kwinjira mu cyuho cy'umuzingo, cyangwa ngo ube ibice gusa iyo ushyizwemo ku ngufu.

Ikibazo cya kabiri kibaho iyo rubber iri mu rwego rwo hejuru rwo gukurura, hamwe n’uburyo ikora bwa pulasitiki kandi ikaba ifite ubushobozi bwo gukurura cyane. Ibikoresho bya rubber bizingirwa gusa ku rubber rw’imbere nyuma yo kunyura mu cyuho cy’urubber, ibyo bikaba ingirakamaro mu kuvanga no gukwirakwiza ikintu giteranya ibintu mu rubber.

Icya gatatu kibaho iyo ubushyuhe buri hejuru cyane, amazi ya rubber ariyongera, imbaraga za molekile zigabanuka, kandi imbaraga n'ubudahangarwa biragabanuka. Muri iki gihe, firime ntishobora gupfunyika neza ku rubber ngo ikore ishusho isa n'ishashi, bigatuma urubber rucika cyangwa rukameneka, kandi ntirushobora kuvangwa.

Icya kane kibaho iyo ubushyuhe bwinshi, aho irangi rihinduka rikava ku buryo bworoshye cyane rikajya ku buryo butoshye, hafi ya ryose nta buryo bworoshye n'imbaraga, bigatuma bigorana gukata ibikoresho bya rubi. Bityo rero, ubushyuhe bw'imvange bugomba kugenzurwa kugira ngo ibikoresho bya rubi bigume mu buryo bwiza, ibyo bikaba byiza mu buryo bwo kuvanga.

2. Ifu yo kurya

Icyiciro cyo kurya ifu kivuga ku kuvanga imvange mu bikoresho bifatanye. Nyuma yuko imvange y'umupira ipfundikiwe, kugira ngo imvange mu buryo bwihuse mu imvange, ingano runaka ya kole ikusanyirijwe hamwe igomba kuguma ku mpera yo hejuru y'icyuho cy'imvange y'umupira.

Iyo wongeyeho umuti uvangavanze, bitewe no guhindagurika no gusimbuza kole yakusanyijwe, umuti uvangavanze ujyanwa mu minkanyari no mu miyoboro ya kole yakusanyijwe, hanyuma ukajya mu mwobo w'umuzingo.

Mu gihe cyo kurya amakaroni, ingano ya kole yakusanyijwe igomba kuba iringaniye. Iyo nta kole yakusanyijwe cyangwa kole yakusanyijwe ikaba nto cyane, ku ruhande rumwe, ikintu giteranya ibintu cyishingikiriza gusa ku mbaraga zo gukata hagati y’umuzingo w’inyuma n’umuzingo kugira ngo gikoreshwe mu bikoresho bya karubo, kandi ntigishobora kwinjira imbere mu bikoresho bya karubo, ibyo bigira ingaruka ku gukwirakwira; Ku rundi ruhande, ibikoresho by’ifu bitarasutswe muri karubo bizasukwamo ibice n’umuzingo w’inyuma hanyuma bigwe mu isahani ikira. Niba ari ikintu cy’amazi, kizafata ku muzingo w’inyuma cyangwa kigwe ku isahani ikira, bigatera ingorane mu kuvanga.

Iyo kole irundanyije cyane, kole imwe izazenguruka ikazunguruka ku mpera yo hejuru y'icyuho cy'umugozi, imashini isya imigozi ya rubber, ikayibuza kwinjira mu cyuho kandi bikagorana ko ivangavanga. Ingano ya kole ikunze gupimwa n'inguni yo gufatanya (cyangwa inguni yo guterura), muri rusange iri hagati ya 32-45.

3. Gutunganya no gutunganya

Icyiciro cya gatatu cyo kuvanga ni ugutunganya. Bitewe n'ubukana bwinshi bwa rubber, mu gihe cyo kuvanga, ibikoresho bya rubber binyura mu cyerekezo cyo kuzenguruka cy'urusyo rufunguye, nta muvuduko unyuramo. Byongeye kandi, rubber inyura mu cyerekezo cyo kuzenguruka ni laminar. Kubwibyo, mu kuvanga imbere, urwego rwo gufatana rufata neza ku buso bw'urusyo rw'imbere ku kigero cya 1/3 cy'ubugari bwa firime ntirushobora gutemba kandi ruhinduka "urwego rwapfuye" cyangwa "urwego rudahagarara".

Byongeye kandi, kole yakusanyije ku gice cyo hejuru cy'icyuho cy'umuzingo nayo izakora "agace k'umuzingo" gafite ishusho y'agace gato. Impamvu zavuzwe haruguru zose zituma habaho gukwirakwira gukabije kw'ikintu giteranya ibintu mu bikoresho bya rubber.

Kubwibyo, ni ngombwa kunyura mu byiciro byinshi byo gutunganya, gukata ukoresheje ibyuma by'ibumoso n'iburyo, imashini isohora irangi, gupfunyika cyangwa gupfunyikaho mpandeshatu, gukata, nibindi, kugira ngo uce agace kapfuye n'agace ka reflux, ukore imvange imwe, kandi urebe neza ko ari nziza kandi ihuye.
