Lo ngumbuzo esibuzwa kakhulu. Impendulo inguyebo, irabha ye-silicone ingaba sengozini. Kodwa-ke, inqubo ihluke kancane kune-vulcanization evamile.
Irabha ye-Silicone ivulwa kusetshenziswa inqubo ebizwa ngokuthi i-peroxide vulcanization. Kule nqubo, irabha ye-silicone ihlanganiswe ne-peroxide compound bese ifudumala. Lokhu kudala izixhumanisi eziphambanayo phakathi kwama-molecule erabha ye-silicone, eyinika amandla andayo nokuqina.
Ngakho-ke usunakho! Irabha ye-Silicone ingaba sengozini, kodwa idinga inqubo ehlukile kune-vulcanization evamile.
Yini i-vulcanization?
I-Vulcanization inqubo yokwelapha irabha ukuyinikeza izimfanelo ezithile ezifiselekayo, njengamandla, ukunwebeka, nokumelana nezinyibilikisi nokushisa. Inqubo ngokuvamile ihilela ukwelapha irabha ngesibabule noma amanye ama-agent.
Iyini irabha ye-silicone?
Irabha ye-Silicone iyi-elastomer eyakhiwe nge-silicone-yona ngokwayo i-polymer-equkethe i-carbon, i-hydrogen, nomoya-mpilo. Irabha ene-vulcanized inoma iyiphi irabha eye yabhekana nenqubo ye-vulcanization ukuze ithuthukise amandla ayo, ukunwebeka, nokumelana nokushisa.
Inqubo ye-vulcanization
I-Vulcanization inqubo yamakhemikhali lapho ama-molecule e-polymer ngayinye exhunyaniswa namanye ama-molecule e-polymer ngamabhuloho e-athomu. Umphumela uba inethiwekhi enezinhlangothi ezintathu zamaketanga e-polymer axhumene anikeza into ebalulekile amandla ayo alinganayo kanye nokumelana nokugeleza. Irabha eshisiwe inamandla amakhulu okuqina, ukumelana nezinyembezi, ukumelana nesethi yokucindezelwa, nokumelana nokuhuzuka kunerabha engalashiwe.
Isetshenziswa kanjani i-vulcanization?
I-Vulcanization isetshenziswa emikhiqizweni eminingi, ikakhulukazi amathayi namacansi enjoloba namaphedi. Ibuye isetshenziselwe ukwenza amapayipi, i-silicone o-ring gaskets, nezinye izingxenye zenjoloba ezibunjiwe nezikhishiwe. Irabha eyenziwe nge-vulcanized inezinzuzo eziningi ngaphezu kwerabha engashisi, noma “eluhlaza”, okuhlanganisa ukunwebeka okuthuthukisiwe, amandla aqinile, ukumelana nokuhuzuka nokuklebhuka, nokumelana nokuguga kwemvelo.
Izinzuzo ze-vulcanization
I-Vulcanization inqubo lapho i-polymer material iphathwa ngokushisa noma amakhemikhali ukuze kuthuthukiswe ukusebenza kwayo nokuqina. Injoloba eyenziwe nge-vulcanized isetshenziswa ezintweni ezahlukahlukene, kufaka phakathi amathayi emoto, ukufakwa kwepayipi le-silicone, kanye nama-gaskets okuvalwa kwe-silicone. Ibuye isetshenziswe embonini yokudla kumashubhu, izimvu zamanzi, neminye imikhiqizo ehlangana nokudla.
Kunezinzuzo eziningana ze-vulcanization. Okokuqala, kwandisa ukunwebeka kwenjoloba, okwenza ukuthi imelane nokuklebhuka nokuhuzuka. Okwesibili, yenza injoloba ikwazi ukumelana nokushisa, amakhaza nokuhlaselwa ngamakhemikhali. Okwesithathu, inciphisa ukugeleza kwenjoloba, okwenza kube mancane amathuba okuba ivuze. Okokugcina, i-vulcanization ithuthukisa ukunamathela kwenjoloba kwezinye izinto, iyenze ilungele ukusetshenziswa lapho kudingeka khona uphawu oluqinile.
Izithiyo ze-vulcanization
Nakuba i-vulcanization kuyinqubo esetshenziswa kabanzi enezinzuzo eziningi, kunezinye izithiyo ezingaba khona okufanele zicatshangelwe futhi. Lokhu kubandakanya:
-Ithuba lokudala udoti onobungozi bemvelo
-Amandla okuba sengozini yezakhiwo zemishini
-Amathuba okwenyuka kwezindleko
Ikusasa le-vulcanization
Ikusasa le-vulcanization libukeka lithembisa, ngocwaningo oluqhubekayo nokuthuthuka okuholela ezindleleni ezintsha nezithuthukisiwe zokuvuvukala. Enye indawo okugxilwe kuyo ukuthola izindlela zokunciphisa noma zokuqeda ukusetshenziswa kwamakhemikhali ezinqubweni ze-vulcanization. Lokhu kuzoba nenani lezinzuzo, okuhlanganisa ukunciphisa umthelela wendawo kanye nokwenza imikhiqizo evuthwe imvelo ikwazi ukusimama. Ukwengeza, ukuqeda isidingo samakhemikhali kuzokwenza kube lula futhi kubize kakhulu.
Imibuzo Evame Ukubuzwa mayelana ne-vulcanization
Ingabe irabha ye-silicone ingaba sengozini?
Yebo, irabha ye-silicone ingavuthwa kusetshenziswa isibabule noma ezinye izinto ezilimazayo. Kodwa-ke, kufanele kuqashelwe ukuthi izinhlobo ezithile kuphela zama-rubber abicah zingase zibe vulcanized. Isibonelo, ama-silicone okwelapha okwengeza awakwazi ukufakwa sengozini.
