Ngokwenhloso eyinhloko yokuklama amafomula enjoloba, amafomula angahlukaniswa abe amafomula ayisisekelo, amafomula okusebenza, namafomula asebenzayo.
1, Ifomula eyisisekelo
Ifomula eyisisekelo, eyaziwa nangokuthi ifomula evamile, ngokuvamile idizayinelwe injongo yokuhlonza irabha eluhlaza nezithasiselo.Uma kuvela uhlobo olusha lwerabha ne-ejenti ehlanganisayo, ukusebenza kwayo okuyisisekelo kokucubungula kanye nezakhiwo zomzimba nezomshini kuyahlolwa.Umgomo wokuklama kwawo ukusebenzisa izilinganiso zemix yendabuko nezakudala ukuze uqhathanise;Ifomula kufanele yenziwe ibe lula ngangokunokwenzeka ngokukhiqiza kabusha okuhle.
Ifomula eyisisekelo ihlanganisa kuphela izingxenye eziyisisekelo, futhi impahla yerabha eyakhiwe yilezi zingxenye eziyisisekelo ingabonisa kokubili ukusebenza kwenqubo okuyisisekelo kwento yerabha kanye nezakhiwo eziyisisekelo zomzimba nemishini yerabha evuthisiwe.Kungashiwo ukuthi lezi zingxenye eziyisisekelo zibalulekile.Ngokwesisekelo sefomula eyisisekelo, thuthukisa kancane kancane, lungiselela, futhi ulungise ukuze uthole ifomula enezidingo ezithile zokusebenza.Amafomula ayisisekelo eminyango ehlukene avame ukuhluka, kodwa amafomula ayisisekelo we-adhesive efanayo ngokuyisisekelo ayafana.
Amafomula ayisisekelo amarabha aziqinisayo njengenjoloba yemvelo (NR), irabha ye-isoprene (IR), kanye nerabha ye-chloroprene (CR) angenziwa ngenjoloba ehlanzekile ngaphandle kokugcwalisa ama-ejenti aqinisayo, kuyilapho eyerabha emsulwa ngaphandle kwerabha yokwenziwa yokuziqinisa. (njengenjoloba ye-butadiene styrene, irabha ye-ethylene propylene, njll.), izakhiwo zabo zomzimba nemishini ziphansi futhi azinakwenzeka, ngakho-ke ama-fillers aqinisayo (ama-reinforcing agents) adinga ukungezwa.
Isibonelo sefomula eyisisekelo esimele kakhulu njengamanje siyifomula eyisisekelo yezinhlobo ezahlukahlukene zenjoloba ehlongozwayo kusetshenziswa i-ASTTM (American Society for Testing and Materials) njengezinga elijwayelekile.
Ifomula evamile ecaciswe i-ASTM kanye nefomula eyisisekelo ephakanyiswe amafekthri erabha yokwenziwa inenani elikhulu lokubhekisela.Kungcono kakhulu ukwakha ifomula eyisisekelo esekelwe esimweni esithile seyunithi kanye nedatha yokuhlangenwe nakho eqoqiwe yeyunithi.Kufanele futhi kuqashelwe ekuhlaziyeni izinzuzo nezinkinga zamafomula asetshenziswa ekukhiqizweni kwamanje kwemikhiqizo efanayo, kuyilapho kucutshungulwa ukusetshenziswa kobuchwepheshe obusha enqubweni yokukhiqiza imikhiqizo emisha kanye nokuthuthukiswa kwefomula.
2. Ifomula yokusebenza
Ifomula yokusebenza, eyaziwa nangokuthi ifomula yobuchwepheshe.Ifomula edizayinelwe ukuhlangabezana nezimfuneko ezithile zokusebenza, ngenhloso yokuhlangabezana nezimfuneko zokusebenza komkhiqizo nezinqubo, kanye nokuthuthukisa izici ezithile.
Ifomula yokusebenza ingacabangela ngokugcwele inhlanganisela yezakhiwo ezihlukahlukene ngokusekelwe kufomula eyisisekelo, ukuze kuhlangatshezwane nezidingo zemibandela yokusetshenziswa komkhiqizo.Ifomula yokuhlola evame ukusetshenziswa ekuthuthukisweni komkhiqizo ifomula yokusebenza, okuyifomula esetshenziswa kakhulu abaklami befomula.
3. Ifomula esebenzayo
Ifomula esebenzayo, eyaziwa nangokuthi ifomula yokukhiqiza, iyifomula edizayinelwe umkhiqizo othile.
Amafomula asebenzayo kufanele acabangele ngokugcwele izici ezifana nokusebenziseka, ukusebenza kwenqubo, izindleko, nezimo zemishini.Ifomula esebenzayo ekhethiwe kufanele ikwazi ukuhlangabezana nezimo zokukhiqiza ezimbonini, ithole ibhalansi engcono kakhulu phakathi kokusebenza komkhiqizo, izindleko, nenqubo yokukhiqiza.
Imiphumela yokuhlolwa yamafomula akhiwe ngaphansi kwezimo zaselabhorethri ingase ingabi imiphumela yokugcina.Ngokuvamile, kungase kube khona ubunzima bezobuchwepheshe lapho kufakwa ekukhiqizeni, njengesikhathi esifushane sokupheka, ukusebenza kabi kwe-extrusion, amarola okunamathelayo aginqikayo, njll. Lokhu kudinga ukulungiswa okwengeziwe kwefomula ngaphandle kokushintsha izimo zokusebenza eziyisisekelo.
Kwesinye isikhathi kuyadingeka ukulungisa ukusebenza kwenqubo ngokunciphisa kancane ukusebenza komzimba nokomshini kanye nokusebenza kokusetshenziswa, okusho ukwenza ukuvumelana phakathi kokusebenza komzimba nokomshini, ukusebenza kokusetshenziswa, ukusebenza kwenqubo, nomnotho, kodwa okubalulekile ukuhlangabezana nobuncane obuncane. izidingo.Ukusebenza kwenqubo yezinto zenjoloba, nakuba kuyisici esibalulekile, akusona isici esiphelele, ngokuvamile esinqunywa izimo zokuthuthukiswa kwezobuchwepheshe.
Ukuthuthukiswa okuqhubekayo kwezinqubo zokukhiqiza kanye nobuchwepheshe bemishini kuzokwandisa ukuguquguquka kwezinto zenjoloba, njengokulawula izinga lokushisa okunembile kanye nokusungulwa kwezinqubo zokukhiqiza eziqhubekayo ezizenzakalelayo, okwenza kube nokwenzeka ngathi ukucubungula izinto zenjoloba phambilini ezazibhekwa njengezinomsebenzi ompofu wenqubo.Kodwa-ke, ocwaningweni nasekusetshenzisweni kwefomula ethile, izimo ezithile zokukhiqiza kanye nezidingo zenqubo yamanje kufanele kubhekwe.
Ngamanye amazwi, umklami wefomula akufanele abhekane nekhwalithi yomkhiqizo oqediwe kuphela, kodwa futhi acabangele ngokugcwele ukusebenza kwefomula ezinqubweni ezihlukahlukene zokukhiqiza ngaphansi kwezimo ezikhona.
