Indlela iConical Twin Screw Extruders ewuGuqulela ngayo uShishino lwePlastiki: I-Paradigm Shift ekuqhubekiseni ukuGqwesa

Kummandla oguquguqukayo wokusetyenzwa kweeplastiki, i-conical twin screw extruders (CTSEs) ziye zavela njengotshintsho-mdlalo, ziguqula indlela iipolymers ezidityaniswa ngayo, ezixutywe, kunye ne-homogenized. Aba matshini abaguquguqukayo babeke umgangatho omtsha wokusebenza kunye nokusebenza kakuhle, ukujongana nemingeni yezicelo ezifunwayo kunye nokuqhubela phambili imboni yeplastiki kwimida emitsha yezinto ezintsha. Esi sithuba seblogi sihlalutya impembelelo yenguqu yee-CTSE, iphonononga amandla azo awodwa kunye nokutshintsha kweparadigm abayizisayo ekusetyenzweni koluhlu olwahlukeneyo lwemathiriyeli yeplastiki.

Ukutyhila amandla eConical Twin Screw Extruders

Ii-CTSEs zabelane ngemigaqo yoyilo esisiseko yee-twin screw extruders (TSEs), zisebenzisa izikrufu ezibini ezijikelezayo ukuthutha, ukunyibilika, kunye nokuxuba iipholima. Nangona kunjalo, ii-CTSEs zizahlula ngokwazo ngokubandakanya uyilo lwe-conical barrel, apho i-diameter ye-barrel iyancipha ngokuthe ngcembe ukuya ekupheleni kokukhupha. Le geometry yahlukile inika iingenelo ezininzi ezenza ii-CTSE zibe lolona khetho lukhethwayo kuluhlu olubanzi lwezicelo ezibango.

Ukuxutywa okuPhuculweyo kunye ne-Homogenization

I-conical barrel geometry ikhuthaza ukuxuba okunzulu kunye ne-homogenization ye-polymer blends, i-additives, kunye ne-fillers, iqinisekisa ukuhanjiswa okufanayo kwezixhobo kulo lonke ukunyibilika. Esi sixhobo siphezulu sokuxuba sibalulekile ekuveliseni iimveliso ezikumgangatho ophezulu ezineempawu ezifanayo kunye nokusebenza.

Ukunciphisa Uxinzelelo lwe-Shear

Ukuncitshiswa kancinci komphanda kunciphisa uxinzelelo lwe-chear kwi-polymer melt, ukunciphisa ukuthotywa kwepolymer kunye nokuphucula umgangatho wemveliso. Oku kuluncedo ngakumbi kwiipholima ezingevani nokucheba ezithanda ukuthotywa phantsi kweemeko eziphezulu zokucheba.

Ukuphuculwa koZinzo lweMelt

Uyilo lwe-conical luphucula ukuzinza kwe-melt, ukunciphisa umngcipheko wokuqhekeka kwe-melt kunye nokuqinisekisa inkqubo egudileyo, ehambelanayo ye-extrusion. Olu uzinzo luyimfuneko ekuveliseni iimveliso ezikumgangatho ophezulu kunye nemilinganiselo efanayo kunye neempawu zomhlaba.

Ukuguquguquka kwezicelo eziBangayo

Ii-CTSEs zigqwesa ekuphatheni iikhompawundi ezizaliswe kakhulu, iipolymers ezichetywayo, kunye nemixube yepolymer entsonkothileyo, ezenza zilungele usetyenziso olufuna ukuxutywa okuphezulu kunye nomgangatho wemveliso. Ezi zicelo zinzima ziquka:

I-Wire kunye neCable Insulation: Ii-CTSE zisetyenziswa ngokubanzi kwimveliso yocingo olusebenza kakhulu kunye ne-cable insulation, apho ukuxuba okuhambelanayo kunye nokuzinza kwenyibilika kubalulekile.

IiPlastiki zoNyango: Ukukwazi ukuphatha iipolima zenqanaba lezonyango ezinobuthathaka zenza ii-CTSE zilungele ukuvelisa iityhubhu zonyango, ii-catheters, kunye nezinye izixhobo zonyango.

IiPlastiki zeemoto: Ii-CTSE ziqeshwa ekuveliseni iiplastiki zemoto, kubandakanywa ii-bumpers, ii-dashboards, kunye nezixhobo ze-trim zangaphakathi, apho amandla aphezulu kunye nokuqina kubalulekile.

Izicelo zokuPakisha: Ii-CTSE zisetyenziselwa ukuvelisa iifilimu zokupakisha eziphezulu zokusebenza kunye nezikhongozeli, ezifuna iipropati eziphezulu zomqobo kunye namandla omatshini.

Ukudibanisa kunye ne-Masterbatching: Ii-CTSE zigqwesa ekudibaniseni nasekuxubeni kakuhle, apho ukuxuba okuchanekileyo kunye nokusasazwa kwezongezo kunye nezihluzi zibalulekile.

Ukuqukumbela

I-Conical twin screw extruders iguqule ishishini lokulungisa iiplastiki, inika indibaniselwano ekhethekileyo yezakhono ezijongana nemingeni yezicelo ezifunwayo kunye nokuhambisa umgangatho wemveliso obalaseleyo. Ukuxutywa kwabo okongeziweyo, ukunciphisa uxinzelelo lwe-chear, ukuphuculwa kozinzo lokunyibilika, kunye nokuguquguquka kwezinto ezininzi kubenza zibe zizixhobo eziyimfuneko kuluhlu olubanzi lwamashishini. Njengoko imfuno yeeplastiki ezisebenza ngokuphezulu iqhubela ukukhula, ii-CTSEs zikulungele ukudlala indima eyongezelelekileyo ekubumbeni ikamva lokusetyenzwa kweeplastiki, ukuqhuba ukuveliswa kwezinto ezintsha kunye nokuqhubela phambili ishishini ukuya kumabanga amatsha okugqwesa.
