Imichilo yokuvala irabha Zihlukahlukene ngezinto zokwakha, izinqubo kanye nezakhiwo, futhi izinhlobo ezahlukene zemikhiqizo zinomehluko osobala ekusebenzeni kanye nezimo ezisebenzayo. Ukuhlukaniswa kwesayensi kanye nokuqhathaniswa kwezimo okunembile kungathuthukisa ngempumelelo umphumela wokuvala kanye nempilo yesevisi yemikhiqizo, futhi kunciphise izindleko zobunjiniyela kanye nokugcinwa kwemishini. Njengamanje, imichilo yokuvala irabha eyinhloko emakethe ihlukaniswe ngezigaba ezine eziyinhloko: irabha ye-EPDM, irabha ye-PVC, irabha ye-silicone kanye nerabha yesiponji, ngayinye inezinzuzo zokusebenza ezizimele kanye nezinkambu zesicelo ezizinzile, yakha uhlelo oluphelele lomkhiqizo wokuvala oluhlanganisa izimo zokukhiqiza zomphakathi, zezakhiwo, zezimboni kanye nezezinga eliphezulu.
Imichilo yokuvala irabha ye-EPDM zibekwe njengemikhiqizo ekhethekile yobunjiniyela bangaphandle nobezakhiwo, ezinokumelana okuvelele kwesimo sezulu kanye nokumelana nokuguga, ezifanele ukwakha izindonga zangaphandle, iminyango namafasitela, izindonga zamakhethini, imishini yangaphandle kanye nokuvalwa kwangaphandle kwezimoto. Kuyisinqumo sokuqala sokuvala okonga amandla nokuqina kwezakhiwo zomphakathi nezentengiselwano. Imichilo yokuvala irabha ye-PVC ibekwe njengemikhiqizo yendawo yonke yangaphakathi, enokusebenza okubiza kakhulu kanye nezitayela ezicebile, efanele iminyango yangaphakathi, amafasitela, ifenisha, amakhabethe kanye nezinto zikagesi zasekhaya, ezihlangabezana nezidingo zansuku zonke zokuvala ngaphakathi. Imichilo yokuvala irabha ye-silicone iyimikhiqizo ekhethekile ephezulu, efanele izimo zokushisa okuphezulu, ezihlanzekile nezinembile njengemishini yokudla, imishini yezokwelapha, ama-oven kanye nemishini kagesi ephezulu.
Irabha yesiponjiimichilo yokuvalaUkugxila ekufakweni komsindo we-buffer kanye nokuvalwa kwegebe okungajwayelekile, okulungele izimo ezidinga ukumuncwa kokushaqeka, ukunciphisa umsindo kanye nokufakwa okuthambile, okuhlanganisa ukunciphisa umsindo womnyango nefasitela ngaphakathi, ukuvalela imishini yemishini, ukuvalwa kwegebe langaphakathi lemoto kanye nokuvalwa okuvimbela ukushaqeka komzimba webhokisi. Ngokuphathelene nokuhlukaniswa kwesakhiwo, imichilo yokuvala irabha ihlukaniswe ngohlobo oluqinile, uhlobo olungenalutho, uhlobo olunezimbobo eziningi kanye nohlobo olunesimo esikhethekile. Uhlobo oluqinile lunokumelana okuqinile kokuguguleka kanye nokumelana nengcindezi; uhlobo olungenalutho lunokuqina okungcono kanye nomphumela wokuvimbela umsindo; uhlobo olunezimbobo eziningi lubona ukuvalwa kwezingqimba eziningi futhi luthuthukisa ukusebenza kokumelana nokungangeni manzi nomoya; imikhiqizo enesimo esikhethekile yenzelwe imishini ekhethekile kanye nosayizi wegebe okhethekile.
Ekukhetheni ubunjiniyela obusebenzayo, ukuhlobisa okuvamile kwangaphakathi kubeka phambili imichilo yerabha ye-PVC kanye ne-sponge engabizi kakhulu, kuyilapho amaphrojekthi okwakha angaphandle ekhetha imichilo ye-EPDM engamelani nesimo sezulu. Izimo zezimboni ezishisa kakhulu, ezihlanzekile nezinembile zisebenzisa kuphela imichilo yerabha ye-silicone yezinga lokudla kanye nezinga lezokwelapha. Ukufaniswa okunembile phakathi kwezinhlobo zomkhiqizo kanye nezimo zokusetshenziswa kukhulisa ukusebenza kwezinto ezibonakalayo, kugwema ukwehluleka kokuvala ngaphambi kwesikhathi futhi kunciphisa izindleko zokulungisa imishini nobunjiniyela. Ngokuthuthuka okuthuthukisiwe kwemboni yokuvala, imichilo yokuvala irabha eyenziwe ngokwezifiso iye yaba yinto evamile, iletha izixazululo zokuvala eziqondiwe, zobungcweti zezinkambu ezahlukahlukene zezimboni nezakhiwo.
