Iinkqubo ezintathu ezisisiseko ngexesha lokuxuba irabha nomatshini wokuxuba irabha

Umatshini wokuxuba irabha ngokusisiseko uneenkqubo ezintathu kwinkqubo yokuxuba irabha: Ukusonga irabha, i-Eating powder, i-Refining kunye ne-refined.

1. Ukusonga imiqulu

Ngexesha lokuxuba, kunokubakho iimeko ezine ezinokwenzeka apho irabha eluhlaza ibonakala khona kwirola yesixhobo sokugalela esivulekileyo

Imeko yokuqala yenzeka xa ubushushu berola buphantsi kakhulu okanye irabha iqinile, nto leyo ebangela ukuba irabha ihlale kwirabha eqokelelweyo kunye neslayidi, ingakwazi ukungena kwisithuba serola, okanye ibe ziingceba kuphela xa icinezelwe ngenkani.

Imeko yesibini yenzeka xa irabha ikwimeko yokuthamba okuphezulu, kunye nokuhamba kweplastiki kunye nokuguquguquka okufanelekileyo kwe-elastic ephezulu. Izinto zerabha zisongelwa kuphela kwi-roller engaphambili emva kokudlula kwisithuba se-roller, nto leyo eluncedo kwimisebenzi yokuxuba kunye nokusasazwa kwe-agent edibanisayo kwizinto zerabha.

Imeko yesithathu yenzeka xa ubushushu buphezulu kakhulu, ukunyibilika kwerabha kuyanda, amandla aphakathi kweemolekyuli ayancipha, kwaye ukuthamba kunye namandla ayancipha. Ngeli xesha, ifilimu ayinakuyisonga ngokuqinileyo ijikeleze i-roller kwaye yenze imo efana nebhegi, nto leyo ebangela ukuba i-roller iqhekeke okanye iqhekeke, kwaye ayinakuxutywa.

Imeko yesine yenzeka kumaqondo obushushu aphezulu, apho irabha itshintsha ukusuka kwimeko yokuthamba kakhulu ukuya kwimeko yokuxinana, phantse ingabi nabuthambileyo namandla, nto leyo eyenza kube nzima ukusika izinto zerabha. Ngoko ke, ubushushu bokuxuba kufuneka bulawulwe ukuze kugcinwe izinto zerabha zikwimeko entle, nto leyo elungele inkqubo yokuxuba.

2. Impuphu yokutya

Inqanaba lokutya umgubo libhekisa kwinkqubo yokuxuba i-compound agent kwizinto ezinamathelayo. Emva kokuba i-rubber roller isongiwe, ukuze i-compound agent ixutywe ngokukhawuleza ne-rubber, kufuneka kugcinwe inani elithile leglue eqokelelweyo kwisiphelo esiphezulu se-roller gap.

Xa kufakwa i-compound agent, ngenxa yokujika nokutshintsha iglu eqokelelweyo rhoqo, i-compound agent ithwalwa iye kwimibimbi kunye nemingxunya yeglu eqokelelweyo, ize iye kwi-roller gap.

Ngexesha lenkqubo yokutya iinoodles, ubungakanani beglu eqokelelweyo kufuneka bube phakathi. Xa kungekho glu eqokelelweyo okanye ubungakanani beglu eqokelelweyo buncinci kakhulu, kwelinye icala, i-compounding agent ixhomekeke kuphela kumandla okucheba phakathi kwerola engasemva kunye nerabha ukuze igubungele izinto zerabha, kwaye ayinakungena nzulu ngaphakathi kwezinto zerabha, nto leyo echaphazela isiphumo sokusasazeka; Kwelinye icala, izongezo zomgubo ezingakhuhlwanga kwirabha ziya kucinezelwa zibe ziingceba yirola engasemva kwaye ziwele kwitreyi yokuyifumana. Ukuba sisithako solwelo, siya kunamathela kwirola engasemva okanye siwele kwitreyi yokuyifumana, nto leyo ebangela ubunzima ekuxubeni.

Ukuba kukho ukuqokelelana okugqithisileyo kweglue, enye iglue iya kujikeleza ize iqengqeleke kwisiphelo esiphezulu seroller gap, umatshini wokugrinda irabha roller, nto leyo eya kuyithintela ukuba ingangeni kwisithuba kwaye yenze kube nzima ukuba i-mixing agent ixube. Ubungakanani beglue eqokelelweyo buhlala bulinganiswa nge-contact angle (okanye i-bite angle), edla ngokuba phakathi kwama-32-45.

3. Ukucokisa nokucokisa

Inqanaba lesithathu lokuxuba kukucocwa. Ngenxa yokuba irabha inamandla kakhulu, ngexesha lokuxuba, izinto zerabha zihamba kuphela kwicala elijikelezileyo ecaleni kwendlela yokujikeleza yerola yokugaya evulekileyo, ngaphandle kokuhamba kwe-axial. Ngaphezu koko, irabha ehamba kwicala elijikelezileyo i-laminar. Ke ngoko, i-mixer yangaphakathi, umaleko onamathelayo onamathela ngokusondeleyo kumphezulu werola engaphambili malunga ne-1/3 yobukhulu befilimu awunakuhamba kwaye uba "umaleko ofileyo" okanye "umaleko omileyo" we-lab kneader mixers.

Ukongeza, iglu eqokelelweyo kwinxalenye ephezulu ye-roller gap nayo iya kwenza "indawo ye-reflux" emile okwe-wedge. Zonke ezi zizathu zingasentla zibangela ukusasazwa okungalinganiyo kwe-compounding agent kwizinto zerabha.

Kungoko ke, kuyimfuneko ukucokisa izinto ezininzi, ukusika ngeemela zasekhohlo nasekunene, umatshini wokukhupha irabha, ukusonga okanye ukusonga okunxantathu, ukucutha, njl.njl., ukuze kwaphulwe umaleko ofileyo kunye nendawo yokuchacha, kwenziwe umxube ofanayo, kwaye kuqinisekiswe umgangatho kunye nokufana.
