Imikhiqizo yerabha isuselwa kwinjoloba eluhlaza futhi ingezwe ngenani elifanele lama-ejenti ahlanganisiwe. ...
1.Injoloba yemvelo noma yokwenziwa ngaphandle kwama-ejenti ahlanganisiwe noma ngaphandle kokuvuselelwa kwe-vulcanization kubhekiselwa kuyo njengenjoloba eluhlaza. IRubber yemvelo inezakhiwo ezinhle kakhulu, kepha umphumela wayo ngeke ahlangabezane nezidingo zemboni, futhi ngeke zihlangabezane nezidingo ezithile zokusebenza okukhethekile, ngakho-ke kunezicelo eziningi zenjoloba zokwenziwa. ...
Umenzeli omangalisayo ukuze athuthukise futhi athuthukise izakhiwo ezahlukahlukene zemikhiqizo yenjoloba, into eyengeziwe ebizwa ngokuthi i-ejenti ehlanganisiwe. Ama-ejenti ahlanganisiwe ikakhulukazi ameva e-Vulcanization, ama-filler, ama-accelerator we-vulcanization, amapulasitiki, ama-anti-agent agents kanye nama-fouming agents kanye nama-foaming agents.
① Iqhaza le-Edulcanizeng Agent liyafana ne-ejenti yelapha kumapulasitiki we-thermoset. Kwenza amaketanga ama-molecular ama-molecular akha amaketanga avundlile, axhumeke ngokuqondile, futhi abe isakhiwo senethiwekhi, ngaleyo ndlela athuthukise izakhiwo zemishini nezomzimba zenjoloba. I-sulfide ejwayelekile isetshenziswa isibabule ne-sulfide. ...
② I-filler ukuthuthukisa izakhiwo zemishini zenjoloba, njengamandla, ubunzima, ukugqokwa nokuqina. Ama-fillers asetshenziswa kakhulu yi-carbon emnyama nezindwangu, imicu, kanye nezintambo zensimbi noma ama-markis wensimbi njengezinto zokwakha. Ukungeza ama-filler kunganciphisa futhi inani lenjoloba eluhlaza futhi kunciphise izindleko zenjoloba. ...
Amanye ama-acceleerators we-Vulcaning acceleerators angasheshisa inqubo yokuvuselela futhi athuthukise umphumela we-vulcanization; Amapulasitiki asetshenziselwa ukwandisa i-plasticity yenjoloba futhi athuthukise ukusebenza kwenqubo yokubumba; Ama-antioxidants (ama-antioxidants) asetshenziselwa ukuvikela noma ukubambezela ukuguga kwenjoloba.
2.Izici kanye nokusetshenziswa kwemikhiqizo yenjoloba
Imikhiqizo yeRubber inezici zobukhulu obuphezulu, ukuqina okuphezulu, amandla aphezulu kanye nokuphikiswa okuphezulu. I-modulus yayo ye-elastic iphansi kakhulu, yi-1-10 MPA kuphela, futhi ukuguquguquka kwayo okubanzi kukhulu kakhulu, kufika ku-100% kuye ku-1000%. Inokuguquguquka okuhle kakhulu namandla okugcina amandla. Ngaphezu kwalokho, inokumelana okuhle kokuvikeleka, ukufakwa komsindo okuzwakalayo, ukudonswa kanye nokufakelwa. Kodwa-ke, irabha linokumelana nokushisa okumpofu nokuphikiswa okubandayo (okunamathelayo emazingeni okushisa aphezulu, i-brittle lapho kuvezwa kubanda), futhi kuzoncishiswa kuma-solvents. ...
Embonini, irabha ingasetshenziswa ukwenza amathayi, izimbotshana eziqinile nezinamandla, ama-anti-vibration izingxenye, amabhande okuhambisa, amabhande okuhambisa kanye namapayipi, izintambo, amakhabethe, izintambo zikagesi zokufaka izingxenye nezingxenye zokubopha.
