Izvi yakavimbika uye ichiita mabasa akawanda mbishi rabha

Rubber anozivikanwa kubva panguva kuwanikwa America Columbus. MaIndia vakashandisa samafuta muto kuti rabha muti Hevea chisimbiso kumavambiso zvikepe, asika ndiro, isapinda shangu, uyewo nokuda kwezvifananidzo zvaAtemisi balls. Asi Europe kwenguva refu nguva matai zvinonzi nevakawanda hazvina kushandiswa (kusvika XIX remakore). Uye zvose nokuda yakatsvuka rabha pamusoro nguva aiyanika panze uye kuva nesimba. Kugadzirwa kwacho anodzoka rabha kutanga ehupfumi uyewo yaro tembiricha Kudzikamiswa akasika tiguu chaiyo iri zvaAtemisi rabha nyaya.

Sezvo rabha-rabha vaisagona kupa zvishoma nezvishoma kukura kudiwa, pamusoro kwenguva, izvozvo muitiro chokuwana chakaita zvokugadzirwa rabha, izvo isu vachiri kushandisa nhasi. Mazuva ano kugadzira yakatsvuka rabha uye rabha yeimwe. In yayo mbishi chimiro rinoshandiswa kuti kugadzirwa mishonga siyana, sezvo mutemo - chisimbiso uye yokugadzirisa motokari matai uye makamera inopisa nzira (achirapa). Kubva wemisanganiswa anopa zvakawanda zvakasiyana siyana zvinoshandiswa anenge sectors zvose. Vose mumwe nemamwe zvinhu zvinowanikwa muchimiro machira kana kuramba ubvise (padandemutande). Kugadzwa vanogona kuva akasiyana chaizvo - utano, zvokudya, dielectric, mafuta nemishonga, etc.

Kushandiswa mbishi rabha kuti rokugadzirisa matai

Vatyairi kazhinji nemamiriro Muzviitiko zvokuimba kuvadza tai (uyewo Camera). Kazhinji, ukama tai anogona igadziriswe. Izvi zvinogona kuitwa zvose chando uye kupisa vulcanization. Cold rinoitwa kushandisa chaiyo sezvamunoita (butyl activator rukoko), uye inopisa vulcanisation - wakaipa rabha.

Mukomboni rabha zvinoumba nechando vulcanization rinoitwa pasina kupisa kurapwa. Nzira iyi kunotora nguva yakareba uye kunoda kunyatsotevedza hwakagadzwa kwemichina. Hot Kurapwa kunogona kuitwa pane zvose, kusanganisira uye mumunda, zvinhu. Izvi zvinoda chete yakatsvuka rabha uye vulcanizer. Kurapwa angava mira, magiramufomu (vachimhanya kubva 220) uye magiramufomu (yemotokari kumhanya pamusoro pemambure).

How kushandisa yakatsvuka rabha panguva vulcanization

Chokutanga, ukama nzvimbo inofanira zvakasimba kucheneswa kubva tsvina, kurapa sandpaper uye degrease. Zvino unofanira kuisa chigamba vakatema kubva kwakafumuka rabha uye akaisa ari vulcanizer. Kuti adzivise adhesion pakati chigamba uye kuti kudziyisa chinhu chiri yemanyorero papepa tichigadzira.

Zvakaoma rabha sokunge rudzi epurasitiki nezvakavhenganiswa, iyo, kana vulcanization chinopinda zvakakwana zvikuru kupinda lesion uye vakachengetwa embeds nayo. Kana neshungu, zvinova simba, asi anoramba chandagwinyira. The tembiricha panguva iyo Kurapwa kunoitika anenge 140-160 ° ^C. Paaizosvika tembiricha ichi (ndakatsunga nokuchinja Ruvara paper) vulcanizer akochonorwa. Kana chigadzirwa iri dzaserera chose, hazvina vagadzirira mberi kushandiswa.

Not varumbidzwa Usave akakwidziridzwa kutonhora pamusoro 160 ^{° C,} sezvo izvi zvinotungamirira desiccation kuti rabha uye, sezvo mugumisiro - kuti kurasikirwa elasticity.
