Emphakathini wanamuhla, abantu abaningi abazi okuningi ngayo.Ngokuvamile, inqubo yokubumba umjovo kusuka kuma-pellets epulasitiki kuya emikhiqizweni ebunjiwe yomjovo idinga uchungechunge lwezinqubo eziqinile, futhi ukuphatha okwanele kwanoma iyiphi yalezi zinqubo kuzoholela ezinkingeni zekhwalithi yomkhiqizo.
1. I-Rheology yamapulasitiki: Indlela amapulasitiki ageleza ngayo, ageleza futhi aguqule i-viscosity.
2. Injongo, ukusebenza kanye nemiphumela yokulawula izinga lokushisa, ingcindezi, isivinini nokulawula ukupholisa.
3. Ukugcwaliswa kwezigaba eziningi kanye nokulawula ukucindezela kwezigaba eziningi;umphumela we-crystallization, i-amorphous kanye nokuhlelwa kwe-molecular/fiber on inqubo kanye nekhwalithi.
4. Ukuthi ukulungiswa kwezilungiselelo zomshini wokubumba umjovo kuyithinta kanjani inqubo nekhwalithi.
5. Imiphumela yokucindezeleka kwangaphakathi, izinga lokupholisa kanye nokuncipha kwepulasitiki kukhwalithi yezingxenye zepulasitiki.
Namuhla, izingxenye eziningi zomkhiqizo azihlukaniseki emikhiqizweni yokubumba umjovo, ngakho ikhwalithi yemikhiqizo yokubumba umjovo inquma ngokuqondile ikhwalithi, ukubukeka nokusebenza kwemikhiqizo yokubumba.
Udinga ukwazi lezi zinto ngesikhathi sokubumba umjovo
Phakathi kwezici ezihlukahlukene ezithinta ukukhiqizwa komkhiqizo, izinga lokushisa elincibilikayo kanye nezinga lokushisa lesikhunta kunomthelela ekuncipheni kwangempela.Ngakho-ke, lapho uklama i-cavity yesikhunta sokujova ngokunemba, ukuze unqume izimo zokubumba, kubalulekile ukunaka ukuhlelwa kwe-cavity.
Ipulasitiki encibilikisiwe iletha ukushisa esikhunjeni, futhi izinga lokushisa lesikhunta ngokuvamile lisatshalaliswa eduze komgodi, ngendlela eqondile umgijimi oyinhloko ophakathi nendawo.Ngakho-ke, ukuze kuncishiswe iphutha lokushwabana phakathi kwemigodi, kunwetshwe ububanzi obuvumelekile bezimo zokubumba, futhi kuncishiswe izindleko, kubalulekile ukuthatha izinyathelo zokuklama ezifana nebhalansi yesiteshi sokugeleza, ukuhlelwa komgodi, nokuhlelwa kwendilinga egxilile egxile esiteshini esikhulu sokugeleza. .Ngakho-ke, ukwakheka kwesikhala sesikhunta sokujova okunembayo esisetshenzisiwe kufanele sihlangabezane nezidingo zebhalansi kanye nokuhlelwa kwabagijimi okugxile kumgijimi oyinhloko, kanye nesakhiwo somgodi nomgijimi oyinhloko njengomugqa wokulinganisa kufanele kwamukelwe, ngaphandle kwalokho izinga lokuncipha umgodi ngamunye uzohluka..
Yiqiniso, enqubweni yokubumba umjovo, ngaphezu kwethonya lesikhunta somjovo ekubunjweni komkhiqizo, kunezinye izici eziningi.Kuphela uma lezi zici ezithile zilungiswa kahle futhi kusingathwa ngazo enqubweni yokukhiqiza lapho zonke izici zokubumba umjovo zingaqedwa ngempumelelo, ngaleyo ndlela kuqinisekiswe ikhwalithi yokukhiqiza kanye nokubona izinzuzo zokukhiqiza.
Inqubo yokubumba umjovo ovuthiwe ingakhiqiza imikhiqizo yepulasitiki yokusetshenziswa okuhlukahlukene namafomu, njengeizingxenye zemikhiqizo kagesi,izingxenye ezincane ezifanelekile, amagobolondo ukuvikela cores ezibalulekile, njll.
