Umshini Wokukhipha Ishidi le-PP/PS

I-PP (i-polypropylene) iyi-resin yokwenziwa ye-thermoplastic elula esebenza kahle kakhulu.

Inokumelana namakhemikhali, ukumelana nokushisa, ukuvikela ugesi, izakhiwo zemishini ezinamandla aphezulu kanye nokumelana okuhle nokuguguleka. Kodwa-ke, iningi le-PP esiyibonayo emakethe liyaguqulwa. Ngemva kokuguqulwa kwamakhemikhali, ukuguqulwa ngokomzimba, kanye nokuguqulwa kokubonakala, inombala ongcono, ukucutshungulwa kalula, ukumelana nomthelela, kanye nokucaca okuphezulu. Inkambu yokufaka nayo ibanzi kakhulu, imikhiqizo yefayibha (izingubo, izingubo zokulala), izingxenye zezimoto, izitsha zamakhemikhali, ukupakishwa kokudla nemithi, njll.

I-PS (i-polystyrene), i-polystyrene, okuhlanganisa i-polystyrene evamile, i-polystyrene enwetshiwe (i-EPS), i-polystyrene enamandla aphezulu (ama-HIPS) kanye ne-syndiotactic polystyrene (i-SPS). I-polystyrene evamile iyinhlayiya engenambala futhi esobala enokushisa okuhle kakhulu, ukufudumala kanye nokubonakala, futhi kulula ukuyipenda. Izinkambu zokusetshenziswa zifaka phakathi imboni yezinto zokwakha, imboni yezimoto, imboni yokupakisha, njll.

Emkhakheni wamashidi akhishwe ngaphandle, i-PP ne-PS nazo zitholakala yonke indawo ekuphileni kwethu kwansuku zonke. Amashidi e-PP awagcini nje ngokusobala kakhulu, anezakhiwo ezinhle zokuvimbela, aphansi, awanobuthi futhi ahlanzekile, kodwa futhi angaphinde asetshenziswe futhi awakhiqizi amagesi anobuthi noma ayingozi uma eshiswa noma eshiswa. Asetshenziswa kakhulu ekupakisheni ukudla, imithi, amadivayisi ezokwelapha, kanye nezinto zokubhala, njengebhokisi lamajeli, amabhokisi okupakisha ubisi, izitsha zeziphuzo ezibandayo, amabhokisi okudla okusheshayo, ama-oven e-microwave, amashidi okubhala, amafolda, njll. I-PS ifana ne-PP ekusebenzeni kwayo futhi isebenza kahle ekupakisheni ukudla. Iphinde isetshenziswe ekupakisheni imikhiqizo kagesi ngenxa yokukhiqizwa kwayo kukagesi okuphansi okungaguquki.

Ukukhetha Imodeli

Emakethe yamanje, i-PP/PS ama-extruders zisabuswa amamodeli anezikulufo ezilodwa, futhi izindleko zemishini ziphansi kakhulu kunezamamodeli anezikulufo ezimbili. I-PP/PS kaJwell Machinery ukukhiqizwa komshini weshidi Umugqa unomthamo ozinzile wezinto ezibonakalayo futhi ungazifaka kahle izinto zokusetshenziswa ngaphansi kwezinhlobo ezahlukene zamafomula, ukuqinisekisa ukuqina kweshidi nokugwema izinkinga zokuqhekeka kalula nombala ongalingani ngesikhathi sokushisa kweshidi kamuva. Ngaphezu kwalokho, asisazinaki "umthamo". Ekukhiqizweni kwamaphepha e-PP, imodeli yethu yesikulufu esisodwa okwamanje ingafinyelela ukukhiqizwa okuzinzile okungafika kumathani ayi-1.5 ngehora.

Nakuba i-extruder enama-twin screw inezindleko eziphakeme, ingcono kune-extruder ene-single-screw kuzo zonke ezinye izici. I-extruder enama-twin screw inomklamo wesakhiwo sentambo oguquguqukayo, oqinisekisa ukuthi i-extruder iphakela izinto futhi yenza ifomula ihlakazeke kakhulu emgqonyeni, okwenza ishidi lifane kakhulu.

Uma kuqhathaniswa namamodeli afanayo emakethe, imishini yethu isebenza kangcono ngezindleko.

Izici zezisetshenziswa

1Kungakhathaliseki ukuthi isikulufu esisodwa noma isikulufu sewele, kukhona umklamo ohlangabezana nezidingo zokukhiqizwa kwe-PP ne-PS. Isikulufu esisodwa sinesilinganiso eside kanye nokukhishwa kwe-vacuum okwandisiwe; kwimodeli yesikulufu esiphindwe kabili, uhlelo lwe-vacuum oluvumelaniswe nenjini enkulu yesikulufu esiphindwe kabili seluthuthukisiwe futhi lwaklanywa ukuqinisekisa ukuthi umhwamuko wamanzi wezinto ukhishwa ngokugcwele, ngaleyo ndlela kuqinisekiswe ukusebenza kweshidi.

2. Umsebenzi oyingqayizivele "wokusheshisa ukhiye owodwa" wenza imishini ikwazi ukulungisa ngesivinini esiphansi futhi ikhiqize ngesivinini esiphezulu ngaphandle kokushintshashintsha, ngaleyo ndlela inciphise izinga lokususwa kweshidi.

3. Umshini wokugoqa usebenzisa izakhiwo ezimbili: umshini wokugoqa wendabuko noma umshini wokugoqa ozenzakalelayo ngokuphelele, ongahlangabezana nezidingo zamakhasimende zokukhiqiza okuncane okuvamile kanye nokukhiqiza okukhulu, futhi usize amakhasimende ngokuqondile ukunciphisa izindleko zabasebenzi. Ngaphezu kwalokho, umshini wokugoqa ozenzakalelayo ngokuphelele ungasika amashidi amakhulu ngaphandle kokugoqa futhi ngeke kube nenkinga yokungakwazi ukugoqa.

4. Uhlelo lokulawula olusebenza kahle noluzinzile lwenza ingcindezi nesivinini semishini sizinze kakhudlwana. Uhlelo lokulawula olunembile lwenza kube lula ukuthuthukisa umkhiqizo kanye nokusebenza kwemishini.

Control System

1. Ubuhlakani buyindlela yokuthuthuka yomhlaba namuhla futhi buyindlela engenakugwenywa. Kuyisikhuthazo kithi ukungena esigabeni esisha. Ukwenza ubuhlakani bube nobungcweti kakhulu emishinini eyisisekelo nakho kuwukuphishekela okungapheli kwe-JWELL.

2. Yonke imishini isebenzisa ukuguqulwa kwemvamisa yomkhiqizo we-Siemens womugqa wokuqala kanye nokulawulwa kwe-servo ukuze kufezwe ukusebenza kahle okuphezulu, ukunemba okuphezulu, ukuzinza okuphezulu kanye nokuphepha okuphezulu.

3. Isixhumi esibonakalayo somuntu nomshini we-HMI, uhlelo lokulawula oluphakathi, ukuphequlula kwesikrini esisodwa kwamapharamitha esistimu yonke, njengogesi wamanje, ingcindezi, isivinini, izinga lokushisa, njll., kwenza ukusebenza kube lula.

4. Ukwenziwa kwedijithali kusenza sikwazi ukuthola amaphutha ngokushesha lapho imishini yethu yehluleka futhi senze ukulungiswa okukude. Ukuxilongwa kwezinga lesiteshi kanye nokuhlaziywa kwamaphutha kungatholakala nge-HMI, kunciphisa kakhulu ukungasebenzi kwedivayisi kanye nesikhathi sokungasebenzi komshini. Izinhlelo ezisebenzisa idijithali kakhulu futhi ezihlakaniphile zenza ukungasebenzi kwedivayisi kube lula futhi ukulungiswa kube lula.
