Ingaba i-twin screw extruder isebenza njani?

Njengomvelisi okhokelayo we-screw extruder,Qiangshengplasiyaqaphela ukubaluleka kokuqonda ukusebenza okuntsonkothileyo kwe-twin screw extruders ukuxabisa ukuguquguquka kwazo kunye nokusebenza kwazo kwiinkqubo ezahlukeneyo zokusetyenzwa kwepolymer. Esi sikhokelo sibanzi sijonga kwiindlela ze-twin screw extruders, sikuxhobisa ukuba ubambe imigaqo esemva kokusebenza kwazo kwaye uchonge iingenelo zazo ezizodwa.

Undoqo we-Twin Screw Extruders

I-twin screw extruders iguqule imboni yepolymer ngokuzisa indlela entsha yokuphatha izinto, ukuxuba, kunye nokunyibilika. Ngokungafaniyo nezikhonkwane ezisebenzisana nazo, izikrufu ezingamawele amabini zisebenzisa izikrufu ezibini ezidibanisayo ezijikelezayo nokuba kwicala elinye (ezijikelezayo) okanye kumacala achaseneyo (ezijikelezayo). Olu lungelelwaniso lukhethekileyo lunika iingenelo ezininzi ezahlukileyo, ukwenza i-twin screw extruders ibe lukhetho olukhethwayo kwizicelo ezibango.

Ukutyhilwa kweMithetho-siseko yokuSebenza

Ukugqithiswa kwe-Positive Displacement:I-intermeshing ye-screws ephindwe kabini yenza indlela efanelekileyo yokufuduka, iqinisekisa ukuhamba kwezinto ezingaguqukiyo kunye ne-pulsation-free. Esi sixhobo sichanekileyo sokuhambisa sibalulekile kwizicelo ezifuna umgangatho ofanayo wemveliso kunye nolawulo lwenkqubo olungaguqukiyo.

Ukuxutywa okuFanelekileyo kunye ne-Homogenization:Ijiyometri entsonkothileyo yezikrufu ezingamawele ivelisa amandla abukhali okucheba, ikhuthaza ukuxubana ngokucokisekileyo kunye nokudityaniswa kwe-homogenization yepolymer enyibilikayo. Obu buchule bokudibanisa obuphuculweyo bubalulekile ekubandakanyeni izongezo, izihluzi, kunye neepigment kwi-polymer matrix, ukufezekisa ukusasazwa okufanayo kunye neepropathi ezifanelekileyo zemveliso.

Ukuhanjiswa kobushushu okusebenzayo kunye nokunyibilika kwePlastiki:Izikrufu ze-intermeshing kunye nesithuba se-barrel esivaliweyo sibonelela ngommandla omkhulu wokutshintshwa kobushushu, okwenza ukuba ukunyibilika okusebenzayo kunye neplastiki ye-polymer. Oku kukwazi ukuhambisa ubushushu kubaluleke kakhulu ekusetyenzweni kweepolima eziphezulu ze-viscosity kunye nokuphumeza iipropati ezifanayo zokunyibilika.

Ukukhupha umoya kunye nokukhupha umoya:Izikrufu ze-intermeshing kunye noyilo lwe-barrel oluvaliweyo luququzelela ukususwa kweegesi eziguquguqukayo kunye nomswakama kwi-polymer melt. Esi sixhobo sisebenzayo sokukhupha i-gassing sibalulekile ekuveliseni iimveliso ezikumgangatho ophezulu kunye ne-voids encinci kunye namaqamza.

Usetyenziso lwe-Twin Screw Extruders

I-Twin screw extruders ifumene ukuvelela kuluhlu olubanzi lwezicelo zokusetyenzwa kwepolymer ngenxa yokuguquguquka kwazo kunye nokusebenza okuphezulu. Usetyenziso oluqhelekileyo lubandakanya:

Iplastiki kunye nokudibanisa:I-twin screw extruders iyagqwesa ekufakeni iplastiki kunye nokudibanisa iipholima ezahlukeneyo, kubandakanya i-thermoplastics, i-thermosets, kunye ne-elastomers. Zisetyenziswa ngokubanzi kwimveliso yee-masterbatches, i-color concentrates, kunye ne-compounds ezaliswe.

Ukuxutywa kwePolymer kunye nokuxutywa:Ubuchule bokuxuba obunzulu be-twin screw extruders bubenza balungele ukudibanisa kunye nokudibanisa iipholima ezahlukeneyo ukufezekisa iipropathi ezifunwayo kunye neempawu. Obu buchule bokudibanisa bubalulekile ekuveliseni imixube yepolymer kunye nokusebenza okulungiselelweyo.

I-Reactive Extrusion:I-twin screw extruders ifaneleke ngokufanelekileyo ukuqhubela phambili iinkqubo ze-extrusion ezisebenzayo, ezifana ne-polymerization, ukufakwa, kunye nokuthotywa, ngenxa yokuxuba okusebenzayo kunye nokudluliselwa kobushushu.

Uluhlu lweMiqathango:

I-Twin Screw Extruder:Udidi lwe-extruder olusebenzisa izikrufu ezibini ezidibanisayo ukuhambisa, ukuxuba, kunye nokunyibilikisa iipholima.

I-Twin Screw Extruder ejikelezayo:I-twin screw extruder apho izikrufu zombini zijikeleza kwicala elinye.

I-Counter-rotating Twin Screw Extruder:I-twin screw extruder apho izikrufu zijikela kumacala achaseneyo.

Ukugqithiswa kwe-Positive Displacement:Indlela yokuhambisa imathiriyeli eqinisekisa ukuhamba okungaguquguqukiyo kunye ne-pulsation-free.

Imikhosi yokucheba:Imikhosi ebangela ukuguqulwa kunye nokuhamba kwezinto.

I-Homogenization:Inkqubo yokudala umxube ofanayo wamacandelo ahlukeneyo.

I-Melt Plasticization:Inkqubo yokuguqula i-polymer ukusuka kwisiqina ukuya kwimeko etyhidiweyo.

Ukukhupha amanzi:Ukususwa kweegesi eziguquguqukayo kwizinto eziphathekayo.

Ukungenisa umoya:Ukususwa komoya okanye iigesi kwinkqubo evaliweyo.

Ukuqukumbela

I-twin screw extrudersbaye baguqula ukusetyenzwa kwepolymer ngokunika indlela eguquguqukayo nesebenzayo yokuphatha, ukuxuba, kunye nokunyibilika.
