Intshayelelo yesigama soShishino lweRubber (1/2)

Ishishini lerabha libandakanya iintlobo ngeentlobo zamagama obugcisa, apho ilatex entsha ibhekisa kwiloshini emhlophe esikwe ngokuthe ngqo kwimithi yerabha.

I-rubber esemgangathweni ihlukaniswe ibe yi-5, i-10, i-20, kunye ne-50 ye-rubber ye-particle, phakathi kwayo i-SCR5 iquka iindidi ezimbini: i-emulsion rubber kunye ne-gel irabha.

I-adhesive esemgangathweni yobisi iveliswa ngokuqiniswa ngokuthe ngqo, i-granulating, kunye nokomisa i-latex, ngelixa ukubeka i-adhesive standard kwenziwa ngokucinezela, ukugranula, kunye nokomisa ifilimu eyomileyo yomoya.

I-Money viscosity sisalathisi sokulinganisa i-torque efunekayo ukujikeleza kwe-rotor kwi-cavity ye-rubber mold phantsi kweemeko ezithile.

Iirabha eyomileyo umxholo ubhekisa kwiigram ezifunyenwe ngokumisa i-100g yelatex emva kokuqina kweasidi.

Irabha yahlulwe yabairabha ekrwada kwayeirabha ehlanjululweyo, kunye nerabha yangaphambili ekrwada kwaye le yokugqibela ibe yirabha edityanisiweyo.

I-arhente edibanisayo yikhemikhali eyongezwe kwirabha eluhlaza ukuphucula ukusebenza kweemveliso zerabha.

Irabha yokwenziwa yipolima elastiki kakhulu eyenziwe ngee-polymerizing monomers.

Irabha esetyenzisiweyo yimathiriyeli eyenziwe ngenkunkuma esetyenzisiweyo yeemveliso zerabha kunye nenkunkuma yerabha emdaka.

Iiarhente ezitshabalalisayo kunokubangela irabha cross-linking, ngelixaukutshisa kukwenzeka kwangethuba kwesenzeko se-vulcanization.

Iiarhente zokuqinisa kwayefillers ngokulandelelanayo ukuphucula iimpawu ezibonakalayo zerabha kunye nokunciphisa iindleko.

Iiarhente zokuthambisa or iiplasticizers ukwandisa iplastiki yerabha, ngelixaukuguga kwerabha yinkqubo yokulahlekelwa ngokuthe ngcembe kwiimpawu zerabha.

Ii-Antioxidants ukulibaziseka okanye inqanda ukuguga kwerabha kwaye yahlulwe kwiikhemikhali kunye nezixhobo zokulwa nokuguga.

Ukutshiza ngeqabaka kwayeukutshiza ngesalfure bhekisa kwisenzeko sesulfure kunye nezinye izongezo ezitshiza ngaphandle kunye nesalfure precipitating kunye crystallizing, ngokulandelelanayo.

Iplastiki yinkqubo yokuguqula irabha ekrwada kwizinto zeplastiki, ezinokugcina i-deformation phantsi koxinzelelo.

Ukuxuba yinkqubo yokongeza i-agent edibeneyo kwirabha ukwenza i-rubber compound, ngelixaukutyabeka yinkqubo yokufaka uludaka kumphezulu welaphu.

I-Rolling yinkqubo yokuvelisa iifilimu ezigqityiweyo okanye iiteyipu ezivela kwirabha edibeneyo. Uxinzelelo lokuqina, uxinzelelo oluphezulu loxinzelelo, kunye nokwandiswa ngexesha lekhefu kubonakalisa ukunganyangeki kwe-deformation, ukumelana nomonakalo, kunye neempawu ze-deformation yerabha evulziweyo, ngokulandelelanayo.

Amandla eenyembezi ibonakalisa isakhono semathiriyeli ukuxhathisa ukusasazwa kokuqhekeka, ngelixairabha ubulukhuni kwayenxibaukumela ukukwazi kwerabha ukuxhathisa i-deformation kunye nokugqoka kwendawo, ngokulandelanayo.

Irabhaukuxinanaibhekisa kubunzima berabha ngomthamo weyunithi.

Ukumelana nokudinwa ibhekisa kutshintsho lwesakhiwo kunye nokusebenza kwerabha phantsi kwamandla angaphandle ngamaxesha.

Ukuvuthwa kubhekiselele kwinkqubo yokupaka i-rubber clots, kwaye ixesha lokuvuthwa lisukela ekuqinisweni kwe-latex ukuya kwi-dehydration.

Unxweme A ubulukhuni: Ukuqina kubhekiselele kwisakhono serabha ukuxhathisa uhlaselo loxinzelelo lwangaphandle, olusetyenziselwa ukubonisa inqanaba lobunzima berabha. Ukuqina konxweme kwahlulwe kwaba ngu-A (irabha yokulinganisa ethambileyo), B (irabha yokulinganisa eyomeleleyo), kunye no-C (irabha yokulinganisa eyomeleleyo).

Tensile strength: Amandla okuqina, okwakwaziwa njengamandla okuqina okanye amandla okuqina, abhekisele kunyanzeliso kwiyunithi nganye yendawo eyenziwa kwirabha xa itsalwa, ibonakaliswa kwi-Mpa. Amandla e-tensile luphawu olubalulekileyo lokulinganisa amandla omatshini erabha, kwaye ixabiso lawo likhulu, ngcono amandla erabha.

Ubude bokuqina ngexesha lekhefu, ekwaziwa ngokuba yi-elongation, ibhekisa kumlinganiselo wobude obunyuswe kukuxinana kwerabha xa itsalwa kubude bayo bokuqala, ichazwa njengepesenti (%). Isalathisi sokusebenza sokulinganisa iplastiki yerabha, kwaye izinga eliphezulu lokunyusa libonisa ukuba irabha inokwakheka okuthambileyo kunye neplastiki elungileyo. Ukwenza irabha, kufuneka ibe nobude obufanelekileyo, kodwa kakhulu akulunganga.

Ireyithi yokubuyela kwakhona, ekwaziwa ngokuba yi-rebound elasticity okanye ukuqina kwempembelelo, sisalathisi somsebenzi obalulekileyo wokulinganisa ukunwebeka kwerabha. Umlinganiselo womphakamo wokuphinda ubuyele kumphakamo wokuqala xa usebenzisa i-pendulum ukuchaphazela irabha kumphakamo othile ubizwa ngokuba yirebound rebound, echazwa njengepesenti (%). Ixabiso elikhulu, ukuphakama kwe-elasticity yerabha.

Hlubula deformation esisigxina, eyaziwa ngokuba yi-deformation esisigxina, isalathisi esibalulekileyo sokulinganisa i-elasticity ye-rubber. Ngumlinganiselo wobude onyuswe yinxalenye egogekileyo yerabha emva kokuba yoluliwe kwaye itsalwe ngaphandle kwaye ipakishwe ixesha elithile (ngokuqhelekileyo imizuzu emi-3) ukuya kubude bokuqala, echazwe njengepesenti (%). Incinci i-diameter yayo, ingcono i-elasticity yerabha. Ukongeza, i-elasticity yerabha inokulinganiswa ngokuguqulwa kwesigxina.
