Da farko, zaɓi na'urar dumama daidai
Cire robobin da aka ɗora akan dunƙule ta wuta ko gasa shi ne hanya mafi na kowa kuma mafi inganci don sassan sarrafa robobi, amma kada a taɓa amfani da harshen wuta don tsaftace dunƙule.
Hanyar da ta dace kuma mai tasiri: yi amfani da wutar lantarki nan da nan bayan an yi amfani da dunƙule don tsaftacewa.Saboda dunƙule yana da zafi yayin aiki, rarraba zafi na dunƙule har yanzu daidai yake.
Na biyu, zaɓi wakili mai tsabta mai dacewa
Akwai nau'ikan na'urori masu gogewa da yawa (kayan tsabtace dunƙule) a kasuwa, waɗanda galibi suna da tsada kuma suna da tasiri daban-daban.Kamfanonin sarrafa robobi na iya amfani da resins daban-daban don yin kayan tsabtace dunƙule gwargwadon yanayin samar da nasu.
Na uku, zaɓi hanyar tsaftacewa daidai
Mataki na farko na tsaftace dunƙule shine kashe abin da ake sakawa, wato, rufe tashar ciyarwa a ƙasan hopper;Sa'an nan kuma rage gudun dunƙule zuwa 15-25r / min da kuma kula da wannan gudun har sai da narke gudana a gaban mutuwa ta daina gudana.Ya kamata a saita zafin jiki na duk wuraren dumama ganga a 200 ° C.Da zarar ganga ya kai wannan zafin jiki, ana fara tsaftacewa.
Dangane da tsarin extrusion (mutuwar na iya buƙatar cirewa don rage haɗarin matsananciyar matsa lamba a gaban ƙarshen extruder), tsaftacewa dole ne mutum ɗaya ya yi: mai aiki yana lura da saurin gudu da juzu'i daga sashin kulawa, yayin lura da matsa lamba na extrusion don tabbatar da cewa tsarin tsarin bai yi yawa ba.A yayin aiwatar da duka, yakamata a kiyaye saurin dunƙule cikin 20r/min.A cikin aikace-aikacen da ƙananan matsa lamba ya mutu, kar a cire mutu don tsaftacewa a farkon wuri.Lokacin da extrusion ya juyo gaba ɗaya daga guduro mai sarrafawa zuwa resin tsaftacewa, an dakatar da mutu kuma an cire shi, sa'an nan kuma an sake kunna dunƙule (a cikin 10r / min) don ba da damar resin tsaftacewa ya fita.
Na hudu, zaɓi kayan aikin tsaftacewa daidai

Da zarar resin tsaftacewa ya daina fita, za'a iya cire dunƙule daga na'urar.Don sukurori tare da tsarin sanyaya, cire layin tiyo da haɗin murɗa kafin fara na'urar cire dunƙulewa, wanda ƙila a haɗa shi zuwa akwatin gear.Yi amfani da na'urar cirewa don tura dunƙule gaba, fallasa matsayin screws 4-5 don tsaftacewa.
Za a iya tsaftace resin tsaftacewa a kan dunƙule tare da gogewar jan karfe da goga na jan karfe.Bayan an tsaftace resin tsaftacewa akan dunƙule da aka fallasa, za a tura na'urar gaba 4-5 sukurori ta amfani da na'urar cire dunƙule kuma a ci gaba da tsaftacewa.An sake maimaita wannan kuma a ƙarshe an fitar da yawancin dunƙule daga cikin ganga.
