Sonke sihlangabezana nokushintsha umbala komkhiqizo othile emsebenzini wethu wansuku zonke, njengemikhiqizo ye-latex izophenduka ibe mhlophe uma igcinwe ekamelweni lokushisa, futhi intambo yekhebula yokushisisa ye-silicone izobaphuzi lapho izinga lokushisa liphezulu.
Njengoba njei-silicone yokushisa intambo yekhebulaesivame ukusisebenzisa ezimpilweni zethu, yaphenduka yaba phuzi ngemva kokubekwa ezingeni lokushisa eliphezulu elingu-200℃ amahora angu-4.Kwenzakalani?
Le nkinga ingase ixazululwe ngokusebenzisa i-silicone high anti-yellowing vulcanizer C-15.Ngokuvamile, imikhiqizo yezinga lokudla inale mfuneko.
Ukuze ugweme ukuphuzi ngenxa yokwengezwa kwesibabule sesibili, i-anti-yellowing catalyst + anti-yellowing agent kufanele isetshenziswe.Zombili zibaluleke kakhulu.
Kodwa-ke, lezi zinto ezimbili zizokwenza kube ukunamathela kancane ngesikhathi sokukhiqizwa kwengcindezi kawoyela, okuyinto okufanele uyinake.
Engeza izinkulungwane ezingu-2-3 zamafutha a-silicone aqukethe i-hydrogen ngokwenani le-silicone.Amafutha abicah aphezulu ane-hydrogen angakwazi ukuxazulula inkinga yokuphuzi, kodwa umkhiqizo ungase ube brittle futhi unamathele.
Ungafafaza ungqimba lwamafutha abicah esikhunjeni ukuxazulula inkinga yokudiliza.Ngaphezu kwalokho, ibhuloho le-platinum kuphela elingasetshenziswa.
Abakhiqizi bahlaziya ukuthi ukusebenzisa ama-anti-yellowing agents kanye nama-anti-yellowing vulcanizers kuwumqondo omuhle impela, kodwa futhi udinga ukunaka ukuthi intambo yokushisisa ye-silicone oyisebenzisayo ilungile yini.
Awukwazi ukungeza i-ejenti yokukhululwa kwesikhunta esiningi kakhulu, i-zinc stearate, ngakho-ke udinga ukuxhumana nomphakeli ukuthola ukuthi akhona yini amafutha e-hydrogen silicone kuwo ukuze unikeze umphumela wokulwa nokuphuzi.
Impushana ibaluleke kakhulu.Uma insimbi iphezulu kakhulu, izophenduka ibe phuzi.Uma ungazi ukuthi uzokwengeza malini, ungaqale uqhathanise i-vulcanizer evamile (ngaphandle kwe-ejenti evimbela ukuphuzi) ne-vulcanizer ene-anti-yellowing agent.
Qaphela ukuthi ungangezi i-zinc stearate mold agent.Uma namanje kungasebenzi, kutuswa ukuthi usebenzise enye inhlanganisela yerabha noma usebenzise i-platinum vulcanizer.
Uma kunesithwali sesulfure noma isulfure endaweni (njengemikhiqizo enesulfure esanda kubhakwa kuhhavini okwesibili), kuzophinde kubangele ukuthi umkhiqizo we-silicone wokushisa ube phuzi.
Sicela uzizwe ukhululekile ukusithinta ukuze uthole ulwazi olwengeziwe ngentambo yekhebula yokushisisa ye-silicone.
