Sarudza atwin screw extruderpaunoda kusanganisa kwakasimba, kusanganisa, kugadziridza, kana kumhanyisa hupfu, mafirita, uye zvinhu zvinonzwa kupisa senge PVC yakaoma. Iyo pfupi vhezheni: single screws pombi, mapatya screws musanganiswa. Thescrew barrelzvinhu zviri zviviri.
Ndiyo imwe yemibvunzo yekutanga mune chero extrusion purojekiti, uye kuikanganisa kunodhura. Imwe screw extruder uye mapatya screw extruder yakavakirwa basa rakasiyana - imwe ipombi, imwe yacho musanganisi - uye kusarudza pamutengo kana tsika pachinzvimbo cheizvo zvinhu zvako zvinotoda zvinotungamira kuhurombo hwechigadzirwa kana muchina wakawandirwa zvakanyanya basa racho.
Isu tinogadzira screws nemadhiramu ese ari maviri, saka isu hatina chikonzero chekusundidzira iwe kune imwe kana imwe.

Chii chinonzi Single Screw Extruder?
A siruuru imwe extruderinomhanyisa sikuruu imwe inotenderera mukati medhiramu rinopisa. Basa re screw iri nyore: tora chikafu chakasimba kune imwe mugumo, unyungudise kuburikidza nekupisa uye kugera, uye pomba yunifomu inonyunguduka kune imwe magumo pakumanikidzwa kwakasimba. Iyo geometry - feed, compression, uye metering zones - inorongedzerwa kuendesa uye kuvaka kudzvanywa, kwete yehasha musanganiswa.
Kupfava ikoko ndiro simba. Single screw extruder ine hupfumi, yakavimbika, iri nyore kushandisa, uye yakanakisa pakukwira-vhoriyamu yekubudisa chinhu chimwe chinowirirana. Ivo vanomhanyisa yakawanda yenyika pombi, chimiro, shiti, firimu, uye waya-yekuputira mitsara. Izvo zvavasingaite zvakanaka kusanganisa kwakasimba kwekugovanisa, kana kubata zvinhu zvinoda chaizvo, zvinodzorwa musanganiswa.
Chii chinonzi Twin Screw Extruder?
A twin screw extruderinomhanyisa masiruuru maviri padivi nepadivi mumufananidzo-masere ebhororo. Iwo maviri screws intermesh, uye kupindirana ikoko ndiyo pfungwa yese: inogadzira kusanganisa kwakasimba, kufambisa kwakanaka, chiito chekupukuta wega, uye kutonga kwakasimba pamusoro pekugera uye nguva yekugara. Panopomba siruuru imwe chete, siruuru inokanya.
Izvo zvinogadzira mapatya masiruu chishandiso chekubatanidza, masterbatch, reactive extrusion, devolatilization, uye kudyisa mapoda kana mafirita ayo screw imwe inonetsa nayo. Ivo vanobata zvinhu zvinonzwa kupisa senge PVC yakaoma, nekuti iyo yakanaka kuendesa inopa chaiyo kutonga pamusoro penguva yakareba sei inopedza mukupisa. Kutengeserana kunodhura zvakanyanya uye kuoma kwemakanika.
Single Screw vs Twin Screw: Makiyi Misiyano

Sei Single uye Twin Screw Dhizaini Yakasiyana
Musiyano mukugona unouya zvakananga kubva pamavakirwo maviri aya. Siruuru imwe chete shaft ine nzvimbo nhatu pakureba kwayo: nzvimbo yekudyisa inotora mumapellets akasimba, nzvimbo yekumisikidza uko chiteshi chisina kunyunguduka nekuzvibatanidza, uye nzvimbo yemita inopomba iyo inonyungudika kumberi nekumanikidza kwakadzikama. Sikuruu imwe, chibhorani chimwe, basa rimwe rakaitwa zvakanaka.
A twin screw is modular. Maviri ekupindirana shafts akaunganidzwa kubva muzvikamu - kuendesa zvinhu kuti zvifambise zvinhu, kukanya zvidhinha kuti zvisanganise - saka iyo screw profile inogona kugadzirwa kune chaiyo komboni uye kugadziridzwazve kana basa rachinja. Thescrew barrelchibhorani-chisere chinovaka masiruuru ese, anowanzo vakwa muzvikamu zvinodziya, zvinochinjika. Iyo modularity ndiyo inopa twin screw simba rayo rekusanganisa uye kushanduka, uye ndosaka mapatya.screw barrelinodhura yakawanda uye inoda kuti kugadzira kwakanyatsojeka. Pamichina ese ari maviri, iyo clearance pakati pe screw ne barrel ndiyo inosarudza kubuda uye kunyungudika mhando, saka kuvaka kushivirira zvinhu zvakanyanya sekugadziriswa.
Nguva Yekusarudza Imwe Sikirivha Extruder
Svika kune imwe sikuruu kana basa racho rakakwira-vhoriyamu extrusion yechinhu chimwe chinowirirana uye kusanganisa kwakanyanya hakusi chikamu cheequation. Pipe, profile, sheet, firimu, waya coating - iyi inzvimbo imwechete screw, uye hupfumi hwakaoma kurova. Iri zvakare kufona chaiko kana bhajeti raita, kana vashandisi vachida muchina uri nyore kumhanya, kana mutsara uchigadzira chimwe chigadzirwa zuva nezuva. Kana zvinhu zvako zvakatosanganiswa uye iwe unongoda kuigadzira, screw imwe inoita basa iro nemazvo uye zvakachipa.
Nguva Yekusarudza Twin Screw Extruder
Sarudza mapatya siruu nguva iyo maitiro ako anoda kusanganiswa pane kungoumba. Iyo inovhara kusanganisa uye masterbatch kugadzirwa, kusanganisa mafirita segirazi faibha kana calcium carbonate, reactive extrusion, devolatilizing, uye yekudyisa hupfu. Iyo zvakare iri nani sarudzo yezvinhu zvinopisa-sensitive zvinhu zvakaita seyakaomarara PVC, uko chaiyo yekugara-nguva yekudzora inodzivirira iyo polymer. Iwe unobhadhara zvakanyanya kumberi uye muchina unobvunza zvimwe zveanoshanda, asi kune aya mabasa sikoni imwe chete haigone kuunza iwo akafanana chigadzirwa mhando.
Mhando dzeTwin Screw Extruders
"Twin screw" haisi muchina mumwechete. Misiyano miviri inokosha kana iwe ukatsanangura imwe:
Co-Rotating vs Counter-Kutenderera
Mumapatya anotenderedza screws ma screws anotenderera nenzira imwechete. Izvi zvinopa kusanganisa kwakanyanya kwekugovera uye kuzvipukuta, ndosaka michina inotenderera ichitonga kusanganisa uye masterbatch. Mune siruu-inotenderedza mapatya masiruuru anotenderedza akananga kwakatarisana, achigadzira yakanyanya kudzvanywa uye yakasimba inofambisa yakanaka - sarudzo yakajairika kune yakasimba PVC mbiri uye pombi.
Parallel vs Conical
A parallel twin screw inochengeta dhayamita inoramba iripo pakureba kwaro uye ndiro bhiza rinogoneka kune zvakawanda zvekusanganisa. Aconical twin screwmatepi kubva kumucheto wakakura wekudya kusvika kune yakamanikana kubuda, iyo inopa hombe yekudyisa huro uye yakawanda torque nekumhanya kwakaderera - iyo yekirasi gadziriso yeyakaomarara PVC pombi uye chimiro pamitsetse midiki uye yepakati-saizi. Isu tinovhara iyi yekutengeserana mune zvakadzama mune yedu conical vs parallel twin screw gwara.
Zvakajairika Zvikanganiso Pakusarudza Yako Extruder
Zvikanganiso zvishoma zvinodhura zvinouya zvakare uye zvakare:

Ndeupi mutsauko chaiwo pakati peimwe uye mapatya screw extruder?
Funga nezvayo sepombi inopesana nemusanganisi. Asiruuru imweinoshandura shaft imwe kusundidzira kunyungudika kumberi - yakanaka kana uchimhanyisa chinhu chimwe chakatsiga uye chinongoda kuti chiumbwe nekupomba kunze. Atwin screwmeshes maviri shafts pamwechete, uye iyo meshing ndiyo inoita inorema kusanganisa. Saka kana basa riri kusanganisa, kusanganisa mafirita, kana kubata hupfu, unoda mapatya. Yakatwasuka extrusion yeinofanana resin? Single yakawanda.
Ko twin screw iri nani pane siruuru imwe chete?
Kwete chaizvo - ivo vakavakirwa mabasa akasiyana, saka "zvirinani" zvinoenderana neako. Unoda kusanganisa kwakasimba, masterbatch, kana basa rekuita? Mapatya anokunda. Kusundira mavhoriyamu akakwira eresin imwe mupombi, chimiro, kana firimu? Siruuru imwe chete inochipa uye nekupokana kushoma. Kutenga isiriyo yebasa ndiyo chete kukanganisa chaiko.

Iwe unogona - mapatya screw inobata yakawanda-single-screw basa uye yakawanda yakawanda kunze. Asi inodhura zvakanyanya kutenga uye kumhanya, uye inobvunza zvakawanda kune ani ari kuishandisa. Kune yakajeka-yakakwirira-vhoriyamu extrusion yechinhu chimwe, iyo yekuwedzera kugona kunogara isina basa iwe uchibhadhara iyo. Kunze kwekunge iwe uchida kusanganisa kana rusununguko rwekuchinja maumbirwo, namatira nekona imwe chete.
Ndeipi iri nani yePVC?
Kune yakaoma PVC, mazhinji ma processors anoenda mapatya - anopokana-anotenderera kana conical kunyanya - nekuti iyo yakanaka kuendesa inochengeta yakasimba kutonga pamusoro penguva yakareba sei iyi inonzwa kupisa inoramba ichipisa.
