Iyo twin screw extruder inoshanda sei?

Seanotungamira mapatya screw extruder mugadziri,Qiangshengplasinoziva kukosha kwekunzwisisa mashandiro akaomarara emapatya screw extruder kuti akoshese kuita kwavo kwakasiyana-siyana uye kushanda kwavo mune akasiyana mapolymer processing application. Iyi dhairekitori yakazara inoongorora mukati memaitiro emapatya screw extruder, ichikupa simba kuti ubate misimboti kuseri kwekushanda kwavo uye kuona zvakanakira zvakasarudzika.

Izvo zvakakosha zveTwin Screw Extruders

Twin screw extruders yakashandura iyo polymer processing indasitiri nekuunza nzira itsva yekubata zvinhu, kusanganisa, uye kunyungudika. Kusiyana neayo masiruu mamwe, mapatya ekuisa screw anoshandisa maviri intermeshing screws anotenderera angave ari munzira imwe chete (co-kutenderera) kana akapesana (anopoterera-anotenderera). Iyi yakasarudzika kumisikidzwa inopa akati wandei akasiyana mabhenefiti, ichiita mapatya screw extruders iyo yakasarudzika sarudzo yekuda maapplication.

Kuburitsa Mitemo Yekushanda

Positive Displacement Conveying:Iko kupindirana kwemapatya screws kunogadzira yakanaka yekutamisa mashandiro, kuve nechokwadi chekuenderana uye pulsation-isina kuyerera kwezvinhu. Uku kunyatsogona kwekufambisa kwakakosha kune maapplication anoda yunifomu yechigadzirwa mhando uye inopindirana maitiro ekutonga.

Kunyatsosanganisa uye Homogenization:Iyo yakaoma geometry yemapatya screws inogadzira yakanyanya kugera masimba, inokurudzira kunyatsosanganiswa uye homogenization yepolymer melt. Uku kugona kusanganisa kwakawedzera kwakakosha kubatanidza zvinowedzerwa, mafirita, uye pigment mune iyo polymer matrix, kuwana yunifomu kupararira uye yakakwana chigadzirwa zvivakwa.

Inoshanda Heat Transfer uye Melt Plasticization:Iyo intermeshing screws uye yakavharirwa mbiya nzvimbo inopa yakakura pamusoro penzvimbo yekupisa kupisa, ichigonesa kunyungudika kwakanaka uye plasticization yepolymer. Iyi inobudirira yekupisa yekupisa yakanyanya kukosha pakugadzirisa yakakwirira-viscosity mapolymers uye kuwana yunifomu yakanyunguduka zvivakwa.

Degassing uye Venting:Iyo intermeshing screws uye yakavharirwa dhizaini dhizaini inofambisa kubviswa kwemagasi anoputika uye hunyoro kubva mupolymer kunyungudika. Iyi inobudirira degassing kugona yakakosha pakugadzira zvigadzirwa zvemhando yepamusoro zvine mashoma mavoids uye mabhuru.

Zvishandiso zveTwin Screw Extruders

Twin screw extruder vakawana mukurumbira mumhando dzakasiyana dzepolymer processing application nekuda kwekuita kwavo kwakasiyana uye kuita kwepamusoro. Zvishandiso zvakajairika zvinosanganisira:

Plasticization uye Kubatanidza:Twin screw extruders inokunda mupurasitiki uye kubatanidza mapolymer akasiyana, kusanganisira thermoplastics, thermosets, uye elastomers. Iwo anoshandiswa zvakanyanya mukugadzira masterbatches, color concentrates, uye akazadzwa makomisheni.

Polymer kusanganisa uye kusanganisa:Iwo akanyanya kusanganisa masimba emapatya screw extruders anoita kuti ave akanakira kusanganisa uye alloying akasiyana mapolymers kuti awane anodiwa zvivakwa uye hunhu. Uku kugona kusanganisa kwakakosha pakugadzira mapolymer musanganiswa nekuita kwakagadzirirwa.

Reactive Extrusion:Twin screw extruder yakanyatso kuenderana nekuita reactive extrusion maitiro, akadai sepolymerization, kubatanidza, uye kushatisa, nekuda kwekuita kwavo kusanganisa uye kugona kutamisa kupisa.

Tsanangudzo yeMatemu:

Twin Screw Extruder:Imhando ye extruder inoshandisa maviri intermeshing screws kuburitsa, kusanganisa, nekunyungudutsa mapolima.

Co-inotenderera Twin Screw Extruder:A twin screw extruder apo ese ma screws anotenderera achienda kwaakananga.

Counter-inotenderera Twin Screw Extruder:A twin screw extruder apo masiruuru anotenderera achitarisana.

Positive Displacement Conveying:Chinhu chekufambisa michina inovimbisa kuenderana uye kupuruzira-kusununguka kuyerera.

Shear Forces:Masimba anokonzera deformation uye kuyerera kwezvinhu.

Homogenization:Nzira yekugadzira musanganiswa wakafanana wezvikamu zvakasiyana.

Melt Plasticization:Maitiro ekushandura polima kubva pane yakasimba kuenda kune yakanyungudutswa.

Degassing:Kubviswa kwemagasi anoputika kubva pane chinhu.

Venting:Kubviswa kwemhepo kana magasi kubva kune yakavharwa system.

Mhedziso

Twin screw extrudersvakashandura kugadzirwa kwepolymer nekupa nzira inosiyana-siyana uye inoshanda pakubata zvinhu, kusanganisa, uye kunyungudika. Kugadziriswa kwavo kwakasiyana, kunoratidzwa ne intermeshing screws, yakanaka displacement conveying, uye inobudirira kupisa kupisa, inovagonesa kugona mumhando dzakasiyana siyana dzekushandisa, zvinosanganisira plasticization uye komputa, polymer blending uye alloying, uye reactive extrusion. Semugadziri anotungamira mapatya screw extruder, Qiangshengplas yakazvipira kupa vatengi vedu kwete yemhando yepamusoro extruder chete asiwo yakazara rutsigiro negwara. Kana iwe uine chero mibvunzo kana uchida rumwe rubatsiro pakusarudza kana kushandisa twin screw extruder, ndapota usazeza kubata timu yedu ine ruzivo yenyanzvi.
