Ukulingana komatshini kunye nokusebenza kokuxuba kufuna iitshekhi zokwamkelwa okwahlukileyo.
Imibuzo ebuzwa qho
Ngaba ukuxutywa kokusasazwa kungaqhekeza i-pigment agglomerates?
Ukuxutywa kokusasaza ngokuyintloko kuphinda kuhanjiswe izinto; ayizinzisi ngokwayo ukuba uxinzelelo olukhoyo lwanele ukwaphula i-agglomerate. Into yokwenyani inokufaka isandla kuzo zombini iindlela zokuxuba. Vavanya iiagglomerates ezishiyekileyo ngokwahlukeneyo kumbala okanye ukufana kokwakheka phambi kokuba wenze isigqibo sokuba ingaba intshukumo engaphezulu yokuchithachitha kufuneka na.
Ngaba ukwandisa isantya se-screw kuhlala kuphucula ukuxuba?
Hayi Isantya yigalelo lokusebenza, ngelixa ukuxuba okwamkelekileyo sisiphumo semveliso elinganisiweyo. Thelekisa utshintsho lwesantya kunye neemeko zokutyisa, iqondo lobushushu lokunyibilika, umthwalo wokuqhuba kunye novavanyo lomgangatho ekuvunyelwene ngawo. Musa ukwamkela isethingi ye-rpm ephezulu ukuba iimpawu zemveliso ezifunekayo okanye imida yokusebenza ayisafikelelwa.
Ngaba iibhloko zokuxova ezinamaqondo angama-90 zihlala zilungele ukusasazeka?
Hayi. Ububanzi bediskhi, ubude bebhloko bubonke, isalathiso sokuhambisa, iimeko zokuzalisa kunye noqwalaselo olujikelezileyo nazo zifuna ukuphononongwa. Ibhloko engathathi hlangothi inokudlula izinto phantsi kwesenzo senkqubo ejikelezileyo; Ukungathathi hlangothi akuthethi ukuba imathiriyeli ihlala imile.
Ngaba izinto zokuxuba anamazinyo nazo zibonelela ngokuxuba okusasazekayo?
Ewe, kuxhomekeke kwijometri kunye neemeko zokusebenza. Into echazwa njengomxube wokusasaza isenokwenza uxinzelelo lwasekhaya. Cela ubungqina beprofayili yangempela kunye nomsebenzi wezinto eziphathekayo kunokuphatha igama lodidi njengenkcazo epheleleyo yokusebenza kwayo.
Kutheni le nto imibala inokuhlala emva kokongeza iibhloko zokuxova?
Iibhloko ezininzi zokuxova azichongi okanye ziwuphelise ngokwazo unobangela. Jonga ukuzinza kwe-dosing, ifom yesithako esingenayo, iimeko zokunyibilika kunye neesampuli eziqokelelwe phantsi kokusebenza okufanayo. Emva koko jonga ukuba ingaba ingxaki eseleyo lunikezelo lwesithuba, iiagglomerates ezingasasazwanga okanye esinye isiphene phambi kokwenza olunye utshintsho kuqwalaselo.
Kuthetha ntoni ulungelelwaniso lwencakuba yesijivu kwi-twin-screw extrusion?
Kwesi sikhokelo, ulungelelwaniso oluluncedo lulungiselelo lwe-axial yokuhambisa, ukuxova kunye nokuxuba amacandelo, kuquka imilinganiselo kunye nolwalathiso. Sebenzisa la magama athile kumzobo. Ukubiza yonke indibano ngoqwalaselo lweblade ayichazi imisebenzi yayo yokusetyenzwa okanye ukwenza iikhowudi zezinto zababoneleli ezahlukeneyo zitshintshe.
