Ngokwenjongo ephambili yokuyila iifomyula zerabha, iifomyula zinokwahlulwa zibe ziifomyula ezisisiseko, iifomyula zokusebenza, kunye neefomyula eziphathekayo.
1, Ifomula esisiseko
Ifomula esisiseko, ekwabizwa ngokuba yifomula eqhelekileyo, yenzelwe injongo yokuchonga irabha ekrwada kunye nezongezo.Xa uhlobo olutsha lwerabha kunye ne-agent edibeneyo luvela, ukusebenza kwayo okusisiseko kunye neempawu zomzimba kunye noomatshini zivavanywa.Umgaqo woyilo lwayo kukusebenzisa imilinganiselo yokuxuba yendabuko kunye neklasikhi yokuthelekisa;Ifomula kufuneka yenziwe lula kangangoko kunokwenzeka ngokuveliswa kwakhona okulungileyo.
Ifomyula esisiseko ibandakanya kuphela awona macandelo asisiseko, kunye nemathiriyeli yerabha eyenziwe ngala malungu asisiseko angabonisa zombini inkqubo esisiseko yokusebenza kwesixhobo serabha kunye neempawu ezisisiseko zomzimba kunye noomatshini berabha evuthelweyo.Kunokuthiwa la macandelo asisiseko ayimfuneko.Ngokwesiseko sefomula esisiseko, phucula ngokuthe chu, khulisa, kwaye ulungelelanise ukufumana ifomula eneemfuno ezithile zokusebenza.Iifomyula ezisisiseko zamasebe ahlukeneyo zihlala zihluke, kodwa iifomyula ezisisiseko ze-adhesive efanayo ziyafana.
Iifomyula ezisisiseko zerabha eziziqinisayo njengerabha yendalo (NR), irabha ye-isoprene (IR), kunye nerubha ye-chloroprene (CR) inokwenziwa ngerabha esulungekileyo ngaphandle kokuqinisa izihluzi (ii-agent zokuqinisa), ngelixa irabha esulungekileyo ngaphandle kokuziqinisa. (ezifana ne-butadiene styrene rubber, i-ethylene propylene rubber, njl.), iimpawu zabo zomzimba kunye nomatshini ziphantsi kwaye azinakwenzeka, ngoko ke iifayili zokuqinisa (i-agent zokuqinisa) kufuneka zongezwe.
Owona mzekelo wefomyula osisiseko umelweyo ngoku uyifomula esisiseko yeendidi ezahlukeneyo zerabha ecetywayo kusetyenziswa i-ASTTM (uMbutho waseMelika woVavanyo kunye neZixhobo) njengomgangatho.
Ifomula esemgangathweni echazwe yi-ASTM kunye nefomula esisiseko ecetywayo yimizi mveliso yerabha eyenziweyo inexabiso elikhulu lokubhekisela.Kungcono ukuphuhlisa ifomula esisiseko esekelwe kwimeko ethile yeyunithi kunye nolwazi oluqokelelweyo lwamava eyunithi.Kufuneka kuqwalaselwe kwakhona ukuhlalutya okuhle kunye nokungalunganga kweefomula ezisetyenziswayo kwimveliso yangoku yeemveliso ezifanayo, ngelixa kuqwalaselwa ukusetyenziswa kobuchwepheshe obutsha kwinkqubo yokuvelisa iimveliso ezintsha kunye nokuphuculwa kwefomula.
2. Ifomula yokusebenza
Ifomula yokusebenza, eyaziwa ngokuba yifomula yobugcisa.Ifomula eyilelwe ukuhlangabezana neemfuno ezithile zokusebenza, ngenjongo yokuhlangabezana neemfuneko zemveliso kunye nenkqubo, kunye nokuphucula iimpawu ezithile.
Ifomula yokusebenza inokuqwalasela ngokubanzi indibaniselwano yeepropati ezahlukeneyo ngokwesiseko sefomula esisiseko, ukuze kuhlangatyezwane neemfuno zeemeko zokusetyenziswa kwemveliso.Ifomula yokulinga edla ngokusetyenziswa kuphuhliso lwemveliso yifomula yokusebenza, eyona fomyula isetyenziswa kakhulu ngabayili befomula.
3. Ifomula esebenzayo
Ifomula esebenzayo, eyaziwa ngokuba yifomula yemveliso, yifomula eyilelwe imveliso ethile.
Iifomula ezisebenzayo kufuneka ziqwalasele ngokubanzi izinto ezifana nokusebenziseka, ukusebenza kwenkqubo, iindleko, kunye neemeko zesixhobo.Ifomula esebenzayo ekhethiweyo kufuneka ikwazi ukuhlangabezana neemeko zemveliso yemizi-mveliso, ukuzuza eyona ntsalela ilungileyo phakathi kokusebenza kwemveliso, iindleko, kunye nenkqubo yokuvelisa.
Iziphumo zovavanyo lweefomula eziphuhliswe phantsi kweemeko zelabhoratri zisenokungabi ziziphumo zokugqibela.Rhoqo, kusenokubakho ubunzima obuthile bobugcisa xa bufakwa kwimveliso, njengexesha elifutshane lokupheka, ukusebenza kakubi kwe-extrusion, iirola ezincamathelayo ezincamathelayo, njl. njl. Oku kufuna uhlengahlengiso olongezelelweyo lwefomula ngaphandle kokutshintsha iimeko zokusebenza ezisisiseko.
Ngamanye amaxesha kuyimfuneko ukuhlengahlengisa ukusebenza kwenkqubo ngokunciphisa kancinci ukusebenza komzimba kunye noomatshini kunye nokusebenza kokusetyenziswa, okuthetha ukwenza ulungelelwaniso phakathi kokusebenza komzimba kunye noomatshini, ukusebenza kokusetyenziswa, ukusebenza kwenkqubo, kunye noqoqosho, kodwa eyona nto iphambili kukuhlangabezana nobuncinci. iimfuno.Ukusebenza kwenkqubo yezinto zerabha, nangona into ebalulekileyo, ayiyona nto kuphela, edla ngokugqitywa yimeko yophuhliso lwezobuchwepheshe.
Ukuphuculwa okuqhubekayo kweenkqubo zokuvelisa kunye neteknoloji yezixhobo kuya kwandisa ukulungelelaniswa kwezixhobo zerabha, ezifana nokulawulwa kweqondo lokushisa ngokuchanekileyo kunye nokusekwa kweenkqubo eziqhubekayo zokuvelisa ngokuzenzekelayo, okwenza kube lula ngathi ukucubungula izinto zerabha ezazicatshangelwa ukuba zingasebenzi kakuhle inkqubo.Nangona kunjalo, kuphando kunye nokusetyenziswa kwefomula ethile, iimeko ezithile zokuvelisa kunye neemfuno zenkqubo yangoku kufuneka ziqwalaselwe.
Ngamanye amazwi, umyili wefomula akufuneki abe noxanduva lomgangatho wemveliso egqityiweyo kuphela, kodwa kwakhona aqwalasele ngokupheleleyo ukusetyenziswa kwefomula kwiinkqubo ezahlukeneyo zokuvelisa phantsi kweemeko ezikhoyo.
