Izibonelelo zeRubber yeNdalo kunye nendlela yokukhetha iRubber yeNdalo

  Irabha yendalo isetyenziswa kakhulu kwimveliso yeemveliso ezahlukeneyo kunye neemveliso zefektri kuba ineempawu ezahlukeneyo ezibalaseleyo.

  Okokuqala, irabha yendalo inokuqina okulungileyo, ukugquma, umqobo wamanzi kunye neempawu zeplastiki. Ezi zakhiwo zomzimba zinokuqinisekisa ukuba irabha yendalo inokucutshungulwa kwiimfuno ezahlukeneyo zemihla ngemihla, njengeiglavu zonyango, iibhubhu zokumpontshelwa igazi, njl.

Okwesibini, i-rubber yendalo ineempawu ezintle kakhulu zoomatshini, kwaye umgangatho wayo kunye nelahleko yokusebenza iya kuba yincinci kakhulu emva kokucubungula ngokuphindaphindiweyo. Irabha yendalo igcina ukunwebeka okulungileyo kumaqondo obushushu aphantsi naphezulu, iyenza isetyenziswe ngokubanzi ekwenzeni amatayara ahlukeneyo kunye nezinye iimveliso zerabha zamashishini.

Ukongeza, irabha yendalo inokumelana nokubanda okuhle, ukuqina komoya okugqwesileyo, ukungangeni kwamanzi, ukugquma kombane kunye neempawu zokugquma kwe-thermal, ezivumela ukuba zigcine ukusebenza kakuhle kwiindawo ezahlukeneyo.

 Xa ukhetha irabha yendalo, kufuneka uqwalasele idigri yayo ye-vulcanization, ukumelana nokunxiba, ukuxhathisa ukubola, ukuchasana kwempembelelo kunye neminye imiba. Nazi iingcebiso ezithile:

1. Khetha irabha enedigri ezahlukeneyo zevulcanization ngokweemfuno zangempela. Irabha ethambileyo ineelastiki igqwesileyo kwaye ifanelekile kwiimeko ezinotshintsho olukhulu lobushushu kunye nomothuko kunye nokungcangcazela, kodwa ukuxhathisa kwayo ku-corrosion kunye nokumelana nokuqina akubi kakhulu; Irabha esemi-hard ine-elasticity ephakathi kunye nokuqina kwaye ifanelekile ukusetyenziswa kwemihla ngemihla, ngelixa irabha eqinile inokumelana ne-High corrosion, ukumelana nobushushu kunye namandla omatshini, kodwa ukumelana nokunxiba kungaphantsi kancinane kwirabha ethambileyo.

2. Ukunxiba ukuxhathisa. Okungcono ukuchasana kokugqoka, ukuqina kwezinto zerabha, ezinokwandisa ubomi benkonzo yemveliso ukuya kwinqanaba elithile. Ngoko ke, xa ukhetha i-rubber yendalo, qwa lasela ukuchasana kwayo nokugqoka.

3. Ukumelana nokubola. Irabha yendalo inozinzo olululo lweekhemikhali kwaye inokumelana ne-corrosion evela kwi-acids ezomeleleyo ezingenayo i-oxidizing ngokubanzi, i-organic acids, izisombululo zealkaline kunye nezisombululo zetyuwa. Ngoko ke, xa ukhetha irabha yendalo, nikela ingqalelo ekuxhathiseni kwayo ukubola.

4. Ukuchasana kwempembelelo. Irabha yendalo inokuqina okuhle, ukugquma, umqobo wamanzi kunye neepropathi zeplastiki, ngoko inokumelana nempembelelo entle. Xa ukhetha i-rubber yendalo, qaphela ukuba ukuchasana kwayo kwempembelelo kuhlangabezana neemfuno zangempela.

  Irabha yendalo inokugwetywa ngezi ndlela zilandelayo:

1. Qwalasela inkangeleko yerabha. Irabha yendalo idla ngokuba mnyama okanye mnyama bomvu, ngelixa irabha yokwenziwa ikholisa ukuba mhlophe okanye ilula. Ukongeza, irabha yendalo inomphezulu orhabaxa, ngelixa irabha yokwenziwa inomphezulu ogudileyo.

2. Qaphela ukuguquguquka kwerabha. Irabha yendalo ngokuqhelekileyo ibhetyebhetye ngakumbi, ngelixa irabha yokwenziwa iqhelekile ukubhetyebhetye.

3. Gweba ngeemvavanyo ezithile zobungcali. Umzekelo, iimpawu ze-vulcanization, i-Mooney viscosity, iplastiki, ubuninzi, ukumelana, isalathisi se-oksijini, amandla okuqina, imodyuli encinci, umxholo oqinileyo, ixabiso le-pH, ukutshisa okuthe nkqo kunye nokuthe tye, ukubonwa kwezinto eziguqukayo, ukomelela, ukukrazula, umxholo wentsalela kunye nezinye izinto zokugweba. .

4. Uhlobo lwerabha lunokugwetywa kwangaphambili ngokuvumba lwayo, kodwa alunakuqiniseka nge-100%. Iindidi ezahlukeneyo zerabha zinamavumba azo awodwa. Umzekelo: i-rubber yendalo inephunga elinamandla, elifana nephunga lezityalo, kwaye libuye libe nephunga elikhethekileyo lonyango. Ivumba lerabha yokwenziwa lihlaba, lifana nevumba leekhemikhali.

  Ngamafutshane, xa ukhetha irabha yendalo, kufuneka uqwalasele izinto ezininzi ezifana neemeko zokusetyenziswa kwangempela, iimfuno zokusebenza, kunye nohlahlo lwabiwo-mali lweendleko, kwaye uqhube uthelekiso olubanzi kunye nokukhetha.
