Sonke sidibana nokuguqulwa kombala wemveliso kwimisebenzi yethu yemihla ngemihla, njengemveliso yelatex iya kujika ibe mhlophe xa igcinwe kwiqondo lobushushu begumbi, kwaye i-silicone yocingo lwentambo yokufudumeza iyajika ibe tyheli kubushushu obuphezulu.
Kanye njengokubai-silicone yokufudumeza ucingo lwentamboesihlala siyisebenzisa ebomini bethu, yajika yatyheli emva kokubekwa kubushushu obuphezulu obungama-200℃ kangangeeyure ezi-4.Kuqhubekani?
Le ngxaki ingasonjululwa ngokusebenzisa abicah high anti-yellowing vulcanizer C-15.Ngokuqhelekileyo, iimveliso zodidi lokutya zinale mfuneko.
Ukuze ugweme ukutyheli ngenxa yokongezwa kwesulfure yesibini, i-anti-yellowing catalyst + anti-yellowing agent kufuneka isetyenziswe.Zombini zibaluleke kakhulu.
Nangona kunjalo, ezi zinto zimbini ziya kuyenza ibambeke kancinci ngexesha lokuvelisa uxinzelelo lweoyile, nto leyo ekufuneka uyithathele ingqalelo.
Yongeza i-2-3 yamawaka e-hydrogen-containing silicone oil ngokomlinganiselo we-silicone.Ioli ye-silicone equlethe i-hydrogen ephezulu inokusombulula ingxaki ye-yellowing, kodwa imveliso inokuba yi-brittle encinci kwaye incangathi.
Unokutshiza umaleko weoli ye-silicone kwi-mold ukusombulula ingxaki yokubunjwa.Ukongeza, ibhulorho yeplatinam kuphela ingasetyenziswa.
Abavelisi bahlalutya ukuba ukusebenzisa i-anti-yellowing agents kunye ne-anti-yellowing vulcanizers ngokuqinisekileyo yinto efanelekileyo, kodwa kufuneka uqaphele ukuba ingaba ucingo lokufudumeza lwe-silicone oyisebenzisayo lufanelekile.
Awunako ukongeza i-arhente yokukhululwa kwe-mold eninzi, i-zinc stearate, ngoko kufuneka uqhagamshelane nomthengisi ukuze ufumanise ukuba kukho ioli ye-silicone ye-hydrogen kuyo ukuze unikeze umphumo ochasene ne-yellowing.
Umgubo ubaluleke kakhulu.Ukuba umxholo we-iron uphezulu kakhulu, uya kuba tyheli.Ukuba awuyazi ukuba ukongeza kangakanani, unokuqala uthelekise i-vulcanizer eqhelekileyo (ngaphandle kwe-anti-yellowing agent) kunye ne-vulcanizer ene-anti-yellowing agent.
Qaphela ukuba ungafaki i-zinc stearate i-agent yokukhululwa kwe-mold.Ukuba ayikasebenzi, kuyacetyiswa ukuba usebenzise enye ikhompawundi yerabha okanye usebenzise iplatinam vulcanizer.
Ukuba kukho i-sulfure okanye i-sulphur carrier kwindawo (ezifana neemveliso zesulfure-vulcanized ezisanda kubhakwa kwi-oven okwesibini), kuya kubangela ukuba imveliso ye-silicone yokufudumeza iguquke ibe tyheli.
Nceda uzive ukhululekile ukuqhagamshelana nathi ngolwazi oluthe vetshe malunga ne-silicone yocingo lwentambo yokufudumeza.
