Single screw extruder: ilungele imathiriyeli enye kunye nemfuyo jikelele kunye neenkukhu ukutya okusebenzisanayo.
I-Twin screw extruder: isetyenziswa ngokubanzi kwimveliso yexabiso eliphezulu elongezelelweyo emanzini kunye nokutya kwezilwanyana zasekhaya, okufana ne-eel, ufudo, kunye nokutya kwentlanzi yabantwana, kuba amaxabiso ezi mveliso ezithengiswa kwimarike anele ukuhlawula iindleko zokwenziwa kweemveliso usebenzisa. itekhnoloji yesikruphu setwin; Ukongeza, ukutya okukhethekileyo kwasemanzini, okufana nenxalenye yokutya kwasemanzini (enobubanzi obuyi-0.8 ~ 1.5mm), isondlo sasemanzini esityebileyo, kunye nokutya okunomthamo omncinci wemveliso kodwa isoloko itshintsha ifomula, nayo kufuneka iveliswe kusetyenziswa i-twin screw extruder. .
Kufuneka kucaciswe ukuba lo mahluko ungentla awuqinisekanga. Umzekelo, sicebisa ukuba kusetyenziswe izikrufu ezingamawele ukuvelisa ukutya kwasemanzini, kodwa ngoku iinkampani ezininzi zisebenzisa izikrufu esinye ukuvelisa ukutya kwasemanzini. Kukho iiyantlukwano ekusebenziseni ezi zimbini kwisondlo sasemanzini. Ngokufutshane, xa kuthelekiswa nesikrufu esinye, isikrufu esiphindwe kabini sinezi nzuzo zilandelayo:
① Ukuguquguquka kwezinto eziluhlaza kubanzi, ezinokuziqhelanisa nokusetyenzwa kwe-viscosity ephezulu, i-viscosity ephantsi, umxholo we-oyile ephezulu, ukufuma okuphezulu okanye i-viscosity, i-oyile, imathiriyeli ekrwada emanzi kakhulu, kunye nezinye izinto ezinokutyibilika kwisikrufu esinye (SSE) .
② Kukho izithintelo ezimbalwa kubungakanani besuntswana lemathiriyeli ekrwada, enokuziqhelanisa nokusetyenzwa kwemathiriyeli ekrwada ukusuka kumgubo omncinci ukuya kumasuntswana omgubo orhabaxa kunye nokusetyenzwa kwesijivu esinye semathiriyeli ezinobukhulu bamasuntswana ngaphandle koluhlu oluthile.
③ Ukuhamba kwezinto ngaphakathi komgqomo kufana ngakumbi, kwaye umphunga, amanzi, njl njl.
④ Umgangatho wangaphakathi nangaphandle wemveliso ungcono, onokufikelela kwimo entle kakhulu ye-homogeneous kwaye wenze ubume bemolekyuli bezinto ezicwangcisiweyo ngokulinganayo. Umphezulu ugudile ngexesha lenkqubo ye-extrusion. Iinqununu zemveliso zinokufana okuphezulu kunye nokufana okulungileyo.
⑤ Isiphumo sokuvuthwa kunye ne-homogenization singcono, ngokuqhelekileyo kunye neqondo lokuvuthwa kwe-starch elingaphezulu kwe-95%, eyenza ukuba ukutya okusetyenzwa emanzini kugcine uzinzo emanzini, kuthintele ilahleko yezondlo zemveliso, kwaye kube lula ukwetyiswa nokufunxa.
⑥ Isivuno esiphezulu phantsi kwamandla alinganayo. Ukusebenza kakuhle kokuxuba kwenza i-homogenization ngexesha elifanelekileyo lobushushu elifunyenwe yizinto eziphathekayo, isantya sokuvuthwa kwezinto eziphathekayo, kunciphisa ukuguquguquka kweqondo lokushisa, kunye nokuphucula ukuveliswa kweemveliso ezikhutshiweyo.
⑦ Ukwahluka kwemveliso kunye nokuguquguquka kubanzi, kwaye inokuqhuba ukutya okuncinci kwasemanzini, ifomula ye-oyile ephezulu, isiqulatho sokufuma okuphezulu, iimveliso ezincamathelayo eziphezulu, kunye nemibala emininzi, uhlobo lwesandwich, kunye neemveliso ezikhethekileyo.
⑧ Umsebenzi wenkqubo ulungele ngakumbi, kwaye isantya se-spindle sinokuhlengahlengiswa ngokweemfuno zemveliso ecutshungulwayo. Ngenxa yesici sokuzicoca, ukucoca kulungeleka kakhulu, kwaye akukho mfuneko yokuqhawula izixhobo emva kokucubungula ngalunye.
⑨ Iindawo ezisesichengeni zinxiba kancinci. Ingcamango ephosakeleyo eqhelekileyo kukuba i-screw enye inokugqoka okuncinci. Enyanisweni, ngexesha lenkqubo ye-twin screw extrusion, ngenxa yothutho oluzinzileyo lwezinto eziphathekayo kunye neempawu zokuhamba kwezinto, ukunxitywa kwezinto eziphathekayo kwi-screw kunye nomkhono wangaphakathi we-barrel uncinci kune-screw enye. Nangona inani le-screws liseti enye ngaphezulu, ixabiso lezinto ezincedisayo lisengaphantsi kunelo le-screw enye.
⑩ Iindleko zemveliso ziphantsi. Ngenxa yozinzo oluhle lokusebenza kwemodeli ye-screw yamawele, kukho iindleko zokuqalisa ezimbalwa, ukuchithwa kwamanzi kunye negesi encinci, iindleko ezincinci zabasebenzi, ukuhanjiswa kobushushu obuphezulu, isivuno esiphezulu, kunye nezalathi eziphezulu zokukhupha umbane kwinkqubo yokucubungula ukutya. Ukongeza, ixabiso lezinto ezincedisayo liphantsi, kwaye iindleko zokugqibela zokuvelisa zisasezantsi kakhulu xa kuthelekiswa nesikrufu esinye.
Kungenxa kanye ngenxa yeenzuzo ezininzi zesikrufu samawele xa kuthelekiswa nesikrufu esinye ekuveliseni isondlo sasemanzini esikhuthaza ukuba ukhetho lwe-twin screw extruder xa iimeko zivuma kuyo yonke imiba.
Oku kulandelayo ngamanyathelo okhuseleko ekufuneka athathwe xa usebenzisa i-twin screw extruder:
1. Ukhuseleko lomsebenzi:
-Ngaphambi kokuba usebenze i-twin screw extruder, kuyimfuneko ukuba uqhelane neenkqubo zokusebenza zesixhobo, izilumkiso zokhuseleko, kunye nokusetyenziswa kwezixhobo zokuvala ngokukhawuleza.
-Abasebenzi kufuneka banxibe izixhobo zokukhusela ezihambelanayo ukuphepha iingozi kunye nokwenzakala okunokwenzeka ngexesha lokusebenza.
-Ukuqinisekisa ukhuseleko lwendawo yokusebenza ejikeleze izixhobo kwaye uthintele iingozi ezinjengokutyibilika kunye nokungqubana.
2. Ukugcinwa kwezixhobo:
-Gcina kwaye ugcine i-twin screw extruder, kubandakanywa ukucoca, ukuthambisa, ukuqinisa iibholithi, njl. Qinisekisa ukuba izixhobo zisebenza kakuhle.
-Hlola rhoqo izinto ezigugileyo ngokulula ezifana nezikrufu, iiwasha kunye neendibano, kwaye uzitshintshe ngexesha elifanelekileyo ukuqinisekisa ukusebenza okuqhelekileyo kwezixhobo.
-Phuhlisa izicwangciso zolondolozo ezihambelanayo ngokusekelwe kubuninzi bokusetyenziswa kwesixhobo kunye nendawo yokusebenza ukuze kuqinisekiswe ukusebenza okuzinzileyo kwexesha elide lezixhobo.
3. Ukulungelelaniswa kwemathiriyeli ekrwada:
-Ii-Twin screw puffing machines zineemfuno eziphezulu zemathiriyeli ekrwada, kunye nezixhobo ezahlukeneyo zekrwada zinokufuna iiparamitha zenkqubo yokufunxa ezahlukeneyo kunye neendlela zokusebenza.
-Xa ukhetha izixhobo, kuyimfuneko ukuqinisekisa ukuba imodeli kunye neenkcukacha zezixhobo zifanelekile iteknoloji yokucubungula efunekayo ngokusekelwe kwiimpawu zezinto eziphathekayo kunye neemfuno zokucubungula.
4. Ubushushu kunye nolawulo lwesantya:
-Ubushushu kunye nesantya esijikelezayo ziiparameters ezibalulekileyo ezichaphazela ukusebenza kwe-twin screw extruder, kwaye zifuna ukulungiswa okufanelekileyo kunye nokulawula.
-Ulawulo lobushushu kufuneka luhlengahlengiswe ngokwemathiriyeli ekrwada eyahlukeneyo kunye neemfuno zokusetyenzwa. Ubushushu obugqithisileyo bunokukhokelela ekuvuthweni okugqithisileyo okanye ukutshiswa kwemathiriyeli ekrwada, okuchaphazela umgangatho wemveliso.
-Ukulawulwa kwesantya sokujikeleza kwakhona kufuneka kuhlengahlengiswe ngokufanelekileyo ngokusekelwe kwimathiriyeli ekrwada kunye neemfuno zokusetyenzwa. Isantya esiphezulu okanye esiphantsi sokujikeleza sinokuchaphazela umphumo wokucubungula kunye nomgangatho wemveliso.
5. Ubuninzi bezinto eziphathekayo kunye nolawulo lwenkqubo:
-Ulawulo lobuninzi bezinto eziphathekayo kufuneka luhlengahlengiswe ngokweenkcukacha zezixhobo kunye neempawu zezinto eziluhlaza. Umthamo wezinto eziphathekayo ogqithisileyo unokubangela ukuvaleka kwesixhobo, ngelixa umthamo wezinto eziphathekayo ophantsi kakhulu unokunciphisa ukusebenza kakuhle.
-Ukulawulwa kwenkqubo kufuna ulungelelwaniso olufanelekileyo lokutya kunye nokukhutshwa kokulandelelana kwezinto eziluhlaza, ukuqinisekisa ukuhanjiswa okufanayo kwezinto ezibonakalayo kunye nokukhutshwa okuqhelekileyo kokuphuma, kunye nokuphepha ukuvinjelwa kunye nokuxuba izinto.
6. Ukucoca kunye nococeko:
-Xa usebenzisa i-twin screw extruder, ingqalelo kufuneka ihlawulwe kucoceko kunye nolawulo lococeko lwezixhobo, kwaye ukucocwa rhoqo kweentsalela kunye nothuli ngaphakathi kwezixhobo kufuneka kuqhutywe ukukhusela ukungcoliswa komnqamlezo kunye nokukhula kwebhaktheriya.
