Le nerubha emanzi enokwethenjelwa neyinkonzo

I-Rubber iye yaziwa kusukela ekufunyenwe kweMelika nguColumbus. Ama-Indiya asebenzisa umlenze omnyama we- Hevea umthi onobuncwane ukuze unamathele iibhotile zeenqanawa, wenze izitya, izicathulo ezingenawo amanzi, kunye nokwenza ibhola. Kodwa eYurophu, i-rubber ixesha elide yayingasetyenziswanga ngokubanzi (kwada kweXIXX). Kwaye yonke into yokuba i-rubber eluhlaza yabe isomile kwaye yaqina. Ukuqulunqwa kwendlela yokubuyisela iirubha kwiipropati zayo zangaphambili, kunye nokuzinza kweqondo lokushisa, kuye kwadala ukuvelisa kwangempela kwimveliso yeerubha.

Ekubeni iifama zeerubha zazingenakunceda ukunyuka kwexesha, kwithuba elithile, indlela yenziwe ngenjongo yokufumana i -rubber yokwenziwa, esiyisebenzisayo. Kwiimveliso zanamhlanje, iirubhi eluhlaza kunye kunye neerubha. Kwindlela yayo eluhlaza isetyenziselwa ukuveliswa kwazo zonke iintlobo zeemveliso, njengemithetho - iimpawu, kunye nokulungiswa kwamathayi emoto kunye neekhamera ngeendlela ezitshisayo (i-vulcanization). Kwimixube, iimveliso ezahlukeneyo zenziwe, ezisetyenziswe phantse kuwo onke amashishini. Bobabini, kunye nezinye izinto zikhutshwe ngefomathi okanye i-tape eqhubekayo (indwangu). Injongo yabo inokuhluke kakhulu - unyango, ukutya, i-dielectric, i-oil-oil-oil resistant, njl.

Ukusebenzisa irubha eluhlaza ukulungisa amathayi emoto

Abaqhubi beenqwelo-mafutha bahlala behlangabezana neemeko zokulimala komatshini kumatshini (kunye namagumbi). Kwiimeko ezininzi, ithamo elonakalisiweyo lingalungiswa. Oku kunokwenziwa kokubanda kunye nokutshisa okutshisa. Ubunzima bwenziwa ngumbumba okhethekileyo (umququzeleli womgca we-butyl), kunye ne-vulcanization eshushu kunye nerubhi eluhlaza.

Ukuxhamla kwezixhobo zerabha kunye nokubanda okubandayo kwenziwa ngaphandle kokunyanga kobushushu. Le ndlela ithatha ixesha elide kwaye ifuna ukuthobela ngokuthe ngqo kwi-teknoloji esekelwe. Ukutshatyalaliswa okutshitshiswayo kunokwenziwa nakweyiphi na, kuquka kwintsimi, iimeko. Kule nto, kuphela iirubhi eluhlaza kunye ne-vulcanizer iyadingeka. Iimvolisi ziyakuma, ziphathekayo (zisuka kwi-220 V) kwaye ziphathekayo (zisebenza kwi-network network).

Indlela yokusebenzisa i-rubber eluhlaza ye-vulcanization

Okokuqala, indawo yomonakalo kufuneka ihlambuluke ngokucocekileyo, iphathwe nge-sandpaper kwaye iyancipha. Emva koko, kuyimfuneko ukubeka ingxube yerubha eluhlaza kwi-cut and place it in vulcanizer. Ukuthintela ukudibanisa phakathi kwepatch kunye nomsebenzi wokufudumala , iphepha elivame ukufakwa.

Ierubha engcolileyo ibonakala njengoluhlobo lomxube weplastiki, owathi, xa uhlanjululwa, ungena ngokukrakra ngokwaneleyo kumonakalo kwaye ngokuqinisekileyo uyawuvala. Xa livutha, lomelela, kodwa lihlala linyuka. Iqondo lokushisa apho i-vulcanization yenzeka khona kwimeko ye-140-160 ^o- C. Xa lo bushushu bu fi kelelwe (kumiselwe ngenguqu yombala wephepha), i-vulcanizer iyakususwa. Emva kokuba umkhiqizo uphelile ngokupheleleyo, ulungele ukusetyenziswa ngakumbi.

Akukhuthazwa ukuba kuvumele ukunyuka kwamaqondo angaphezu kwama-160 ° C, njengoko oku kubangela ukukhwabanisa i-rubber kwaye, ngenxa yoko, ukulahleka kwe-elasticity.
