Sonke siyazi ukuthi imikhiqizo yepulasitiki ivamise ukuba nezinga lokushwabana, futhi iyancipha uma iba phansi.Imikhiqizo eyenziwe ngezinto ezihlukene inamazinga ahlukene okushwabana.Lapha, sidingida izici ezimbalwa ezinomthelela ekuncipheni kwemigqomo yempahla yepulasitiki ngesikhathi sesigaba sokukhiqiza.Eqinisweni, ekukhiqizeni, uma ufuna usayizi womkhiqizo ufaneleke kakhulu, kuyasiza ukuqonda izici ezithinta ukufinyela.Phela, embonini yezokuthutha zezimboni, iziqukathi ze-plastic turnover ngokuvamile ziyiziqukathi ezisezingeni elilinganiselwe.Ubukhulu bawo kanye nokucaciswa kwawo kunembile ngokwezinga, futhi akukho ukuchezuka.Uma kungenjalo, angeke kushiwo ukuthi i-generalization isezingeni.
Inqubo yokubumba yeibhokisi lokuthenga lepulasitikiukwakhiwa kwe-thermoplastic.Ngenxa yokuguqulwa kwevolumu phakathi nenqubo yokukhiqiza inqubo ye-crystallization, ukucindezeleka kwangaphakathi kukhulu kakhulu, futhi kukhona ukucindezeleka okusala ngaphakathi komkhiqizo wesikhunta, futhi ukuqondiswa kwamangqamuzana kunamandla kakhulu.Ngakho-ke, inezinga eliphezulu lokuncipha kunemikhiqizo yepulasitiki ebeka ukushisa.Inobubanzi obukhulu bokufinyeza kanye nesiqondiso esigqame kakhulu.Njengoba ungqimba lwangaphandle lwento encibilikisiwe luthintana nendawo yesikhunta ngesikhathi sengxenye yepulasitiki ebunjiwe, lupholiswa ngokushesha ukuze lwenze igobolondo eliqinile eliqinile.Futhi sonke siyazi ukuthi i-thermal conductivity yepulasitiki impofu kakhulu, futhi ungqimba lwangaphakathi lwebhokisi le-plastic turnover liphola kancane kakhulu, lenze ungqimba oluqinile oluqinile ngenani elikhulu lokuncipha.Uma ubukhulu bodonga buhamba kancane, ungqimba oluphezulu luzoqina futhi lunciphise kakhulu.

Imbobo yokuphakelayo yosayizi wokusabalalisa impahla eluhlaza kanye nezinye izici zizothinta ngokuqondile indlela yokuhamba, ukusatshalaliswa kwempahla yomkhiqizo, ukufinyela kokuvikela ingcindezi kanye nesikhathi sokubumba, kuthinte ngokungaqondile izinga lokunciphaibhokisi lokuthenga lepulasitiki.Uma imishini ine-inlet eqondile, ingxenye yesiphambano se-inlet inkulu kakhulu, ikakhulukazi uma ikhudlwana, izinga lokunciphisa lizoba lincane kodwa liqondise kakhulu.Ngokuphambene, lapho usayizi wokungena kumncane, isiqondiso sokufinyela sincane, futhi izinga lokushwabana likhulu uma i-inlet iseduze ngokuqhathaniswa nendawo yokungena noma ihambisana nesiqondiso sokugeleza.
Izimo zokubumba zokukhiqiza zinethonya elikhulu ekuncipheni kwezinga leibhokisi lokuthenga lepulasitiki.Isibonelo, uma izinga lokushisa lesikhunta liphezulu futhi izinto ezincibilikisiwe zihamba kancane, kuba khona ukuminyana okuphezulu futhi izinga lokuncipha lizoba likhulu uma kuqhathaniswa.I-crystalline material ine-crystallinity ephezulu kanye nevolumu enkulu, ngakho izinga lokuncipha liba likhulu.Ukusatshalaliswa kwezinga lokushisa kwesikhunta kanye nedigri yokupholisa yangaphakathi nangaphandle kanye nokulingana kokuminyana kwezingxenye zepulasitiki kuzothinta ngokuqondile izinga lokushwabana nokuqondiswa kwengxenye ngayinye yomkhiqizo.Usayizi wengcindezi yokugcinwa kanye nobude besikhathi sokugcina nakho kunomthelela omkhulu kuzinga lokufinyela.Lapho ingcindezi iphakeme futhi iyinde, izinga lokufinyela lincane, kodwa isiqondiso sikhulu.Phakathi nenqubo yokubumba, izinga lokuncipha kwebhokisi lempahla yepulasitiki lingashintshwa ngokufanele ngokulungisa izinga lokushisa lesikhunta nesivinini sokujova ingcindezi kanye nesikhathi sokupholisa.Ngokwalokhu okungenhla, singakwazi ukunquma izinga lokushwabana kwengxenye ngayinye yomkhiqizo ngokusho kwebhokisi lempahla yepulasitiki yokuncipha kodonga lokujiya lokuphakelayo kokuphakelayo kwe-inlet shape kanye nosayizi nokusabalalisa komklamo wesikhunta, bese sibala i-cavity.size.Ngokwezinga langempela lokushwabana lomkhiqizo, shintsha isikhunta futhi ushintshe izimo zokubumba umjovo ukuze ulungise izinga lokuncipha komkhiqizo ukuze uhlangabezane nezidingo zangempela.
