Inkqubela phambili ecacileyo efana nenkqubo ezenzekelayo, ukujonga ixesha lokwenyani kunye nokubekwa esweni kwenkqubo yokurisayikilisha kuphucule ukuchaneka kunye nokunciphisa impembelelo yokusingqongileyo ngokunciphisa inkunkuma.

Rough Ii-DEA yeExturusikwiMachmna

Umatshini we-extrusion unamacandelo alandelayo: i-hopper, i-screw yokondla, izinto zokufudumeza kunye nempompo yegiya. Izinto eziphathekayo zifakwe kumatshini kwi-hopper. Isikrufu sokutyisa esijikelezayo ngokuqhubekayo, esiqhutywa yinjini kunye nebhokisi yegiya, sihambisa imathiriyeli ecaleni komphanda nangedayisi. Izinto zokufudumeza ecaleni kombhobho zigcina amaqondo obushushu alawulwayo ukuze athambe kwaye anyibilike imathiriyeli yepolymer. Emva kokuphuma kwidayisi, into etyhidiweyo ingena kubumba kunye nomngxuma omnye okanye ngaphezulu, apho ipholisa kwaye iqine ibe yimo oyifunayo. Kwezinye iinkqubo, impompo yegiya ibekwe phakathi kombhobho kwaye ife ukuze kuqinisekiswe uxinzelelo oluhambelanayo kwizinto eziphumayo.

I-Polymer Extrusion kunye ne-Injection Molding

Amanqaku oMlinganiselo weViscosity aPhambili kuMatshini we-Extrusion

Ukuphuma kweHopper / Indawo yokutya: Ilinganisa i-viscosity yokuqala yokunyibilika njengoko ipholima iqala ukuthamba.

Indawo enyibilikayo (Mid-Barel): Ibamba inguqu ukuya kwimo yokunyibilika ngokupheleleyo.

Indawo yokulinganisa(Ngaphambi kweMpompo yeGear okanye iDie): Ilinganisa umlinganiselo we-viscosity ye-polymer phantsi kweereyithi zokucheba zokusebenza.

Ukufa kokungena: Ibonelela ngexesha langempela lokunyibilika kwedatha ye-viscosity kwindawo ye-extrusion.

Ukuqonda iPolymer Melt kunye neViscosity

Yintoni i-polymer melt?

Yipolymer eshushu kwimo etyhidiweyo, ebonisa iipropathi zokuhamba ezivumela ukubunjwa ngokukhupha okanye ukubumba. Inyibilika i-viscosity yeepolymers-ukumelana nokuhamba-kuxhomekeke kubunzima bemolekyuli, ubushushu, izinga lokucheba, kunye nezongezelelo, okuphembelela ukomelela nokugqiba kwemveliso yokugqibela. Kwiinkqubo yepolymer extrusion, apho i-polymer etyhidiweyo ikhutshwe ngokufa, kunye ne-injection yokubumba, apho igcwalisa ukubumba phantsi koxinzelelo, igcina ilungilenyibilika i-viscosityibalulekile. Ngokwemveliumlinganiselo we-viscosity we-polymeriindlela, ezifana ne-capillary rheometry engaxhunyiwe ku-intanethi, ihlala iqhwala ngenxa yokulibaziseka, ibangela ukuba utshintshonomgcaviscometer yeepolymersngolwazi lwexesha lokwenyani.

Imingeni kwi-Polymer Extrusion kunye noLawulo lweNkqubo

Iinkqubo yepolymer extrusionkunye nokubumba inaliti kujongana nemiqobo ebalulekileyo ekugcineni ingaguquguqukinyibilika i-viscosity. Ukwahluka ngenxa yokuthambeka kwe-thermal kunye nokuguquguquka kwamazinga okucheba kunokukhokelela ekungalinganininyibilika i-viscosity yeepolymers, ebangela iziphene ezifana nezitenxo zomphezulu okanye ii-voids kwiiprofayili ezikhutshiweyo. Imigca ye-extrusion emikhulu iyasokola kunye neyunifomuumlinganiselo we-viscosity we-polymerngaphaya kokuhamba, ukugcina ukuthotyelwa kulawulo lwenkqubo. Kwi-high-speed-speed injection molding, uhlengahlengiso olwenziwa ngesandla aluphumeleli ukuhambisana namaxesha omjikelezo okhawulezayo, umngcipheko we-warpage okanye ukuzaliswa okungaphelelanga. Le mingeni igxininisa imfuneko yokuqhubela phambilii-viscometer yepolymeriinkqubo, njengei-viscometer yepolymer ezenzekelayo, ukubonelela ngedatha yexesha langempela kwaye unqobe imida yeendlela zendabuko.

Kutheni Melt Viscosity Monitoring Matters

Umlinganiselo we-viscosity we-Melt ubalulekile kwinkqubo ye-polymer extrusion kunye nokubumba inaliti ngenxa yezizathu ezininzi. Kwi-extrusion, i-viscosity ye-melt engaguqukiyo iqinisekisa ukugcwala okufanayo kunye nokuthintela iziphene ezifana nezitenxo zomphezulu okanye ukudumba. Ekubunjweni kwe-injection, ichaphazela ukuzaliswa kwesikhunta, umgangatho wenxalenye, kunye nexesha lokujikeleza, apho ukuhluka kunokukhokelela kwi-warpage okanye ukuzaliswa okungaphelelanga. Ukujongwa kwexesha langempela kuvumela abaqhubi ukuba bahlengahlengise ukushisa, uxinzelelo, okanye ukubunjwa kwezinto eziphathekayo kwi-fly, ukwandisa ukusetyenziswa kwamandla kunye nokunciphisa inkunkuma-iinkxalabo eziphambili njengoko imimiselo yekhabhoni iqinisa ngo-2025.

Ubunzima bomlinganiselo we-polymer melt viscosity buvela kwindalo engeyiyo ye-Newtonian yokunyibilika kwe-polymer, apho i-viscosity iyahluka ngokwezinga lokucheba kunye nembali ye-thermal. Iinkqubo ze-inline polymer-melt viscometer systems zijongana nale nto ngokubonelela ngedatha eqhubekayo, ivumela ulawulo lwenkqubo ukuba iindlela ezingaxhunyiwe kwi-intanethi azikwazi ukuhambelana.
