Uma ufuna into eqinile, ehlala isikhathi eside yephrojekthi yakho elandelayo, ungase uzibuze ukuthi ingabe irabha ye-silicone noma i-tpe iyisinqumo esifanele. Zombili izinto zokwakha zinezinzuzo kanye nezithiyo zazo, ngakho-ke kubalulekile ukukala izinketho zakho ngokucophelela ngaphambi kokwenza isinqumo. Nakhu ukubuka konke okusheshayo kwento ngayinye ukukusiza wenze ukukhetha unolwazi.
Iyini irabha ye-silicone ne-TPE?
Irabha ye-Silicone ne-TPE womabili ama-elastomer, okusho ukuthi ayizinto ezifana nerabha ezingabunjwa futhi zibunjwe. Zombili zisetshenziswa ezinhlelweni ezahlukahlukene, kusuka ku-cookware kuya kumakesi wefoni kuya kumishini yezokwelapha.
Ngakho-ke, uyini umehluko phakathi kwerabha ye-silicone ne-TPE? Irabha ye-Silicone yenziwe nge-silicone, i-polymer yokwenziwa. I-TPE yenziwe ngama-thermoplastic elastomers, ayinhlanganisela yamapulasitiki namarabha.
Uyini umehluko omkhulu phakathi kwerabha ye-silicone ne-TPE?
Kukhona umehluko omkhulu phakathi kwerabha ye-silicone ne-TPE. Irabha ye-Silicone iyirabha yokwenziwa eyenziwe nge-silicone, kuyilapho i-TPE iyi-elastomer eshisayo. Irabha ye-Silicone inokumelana nokushisa okuhle kanye nokumelana nesimo sezulu, kuyilapho i-TPE ingenakho. Irabha ye-Silicone nayo ibiza kakhulu kune-TPE.
Yiziphi izinzuzo nezingozi zenjoloba ye-silicone?
Kunezinhlobo eziningi ezahlukene zezinto ze-polymer ezitholakalayo emakethe namuhla, ngayinye inesethi yayo ehlukile yezakhiwo kanye nezicelo. Izinto ezimbili ezaziwa kakhulu ezisetshenziswa ezimbonini ezahlukahlukene irabha ye-silicone kanye ne-thermoplastic elastomers (TPE). Ukuze unqume ukuthi iyiphi impahla efanele izidingo zakho, kubalulekile ukuqonda umehluko oyinhloko phakathi kwalawa ma-polymer amabili.
Irabha ye-Silicone iyirabha yokwenziwa ye-inorganic eyenziwe ngama-athomu abicah nama-athomu omoya-mpilo. Lesi sici saziwa ngokumelana namazinga okushisa aphezulu, ukukhanya kwe-UV, i-ozone, nomoya-mpilo. Ukwengeza, irabha ye-silicone inokumelana okuhle kakhulu namanzi nomswakama, okuyenza ilungele ukusetshenziswa lapho kungenzeka ukuthintana namanzi. Okunye okuphambene nenjoloba ye-silicone ukuthi ingaba nenani uma iqhathaniswa namanye ama-polymer.
Ama-Thermoplastic elastomers (TPE) ayikilasi lezinto ze-copolymer ezibonisa kokubili izakhiwo ze-thermoplastic ne-elastomeric. Ama-TPE angabunjwa futhi akheke njenge-thermoplastics, kodwa anokuqina kwamarabha. Lokhu kwenza ama-TPE abe yinketho efanelekile yezinhlelo zokusebenza ezidinga kokubili ukuguquguquka nokuqina. Ama-TPE atholakala ebangeni elibanzi lamazinga obulukhuni, awenza afanelekele yonke into kusukela kumathoyizi athambile kuya kumakesi amagobolondo aqinile. Nokho, ama-TPE angaba nzima ukuwasebenzisa kabusha ngenxa yemvelo yawo ehlanganisiwe.
Yiziphi izinzuzo kanye nokubi kwe-TPE?
I-TPE ikilasi lama-thermoplastic elastomers aqukethe kokubili izakhiwo zenjoloba nepulasitiki. Imikhiqizo ye-TPE inezinzuzo eziningi kunemikhiqizo yenjoloba evamile. Zivamise ukuqina, zinokudabuka okukhulu kanye nokumelana nemihuzuko. Ziphinde zimelane namafutha amaningi, amakhemikhali, ukukhanya kwe-UV kanye nezinga lokushisa elibi kakhulu lishintsha kangcono kunerabha. Ama-TPE ayancibilika futhi ageleze njengepulasitiki, ukuze abunjwe umjovo noma akhishwe ngobude obuqhubekayo njengamashubhu erabha. Futhi, njengenjoloba, ama-TPE angabunjwa abe cishe noma yikuphi ukuma ongakucabanga.
Okubi okuyinhloko kwama-TPE ukuzinza kwawo okushisayo okuphansi uma kuqhathaniswa namanye ama-elastomer. Zingaba brittle emazingeni okushisa aphansi futhi zingase zehlise izinga lokushisa eliphezulu. Lezi zimo zokushisa ezeqisayo zingabangela izingxenye ukuthi zisonte noma zihlanekezelwe.
Kunini lapho irabha ye-silicone iyisinqumo esingcono kakhulu?
Nakuba kokubili i-TPE nerabha ye-silicone kuyisinqumo esihle kakhulu sezinhlelo zokusebenza ezihlukahlukene, kunezimo ezithile lapho irabha ye-silicone iyindlela engcono kakhulu.
Uma udinga impahla engakwazi ukumelana namazinga okushisa aphezulu, khona-ke irabha ye-silicone iyindlela yokuhamba. Ingakwazi ukumelana namazinga okushisa afinyelela ku-400 degrees Celsius, iyenze ilungele izinhlelo zokusebenza lapho ukumelana nokushisa kuyisihluthulelo.
Ngaphezu kwalokho, irabha ye-silicone inokumelana okuhle kakhulu nokukhanya kwe-UV kanye ne-ozone, okwenza kube ukukhetha okuhle kwezicelo zangaphandle. Okokugcina, irabha ye-silicone inezinto ezinhle zokuvikela ugesi, okuyenza ilungele ukusetshenziswa kuyo izingxenye zikagesi namadivayisi ishidi.
Kunini lapho i-TPE iyisinqumo esingcono kakhulu?
I-TPE inikeza izinzuzo eziningi ngaphezu kwerabha ye-silicone, okuhlanganisa:
- Ukumelana okungcono ne-UV kanye ne-ozonation
- Ukuguquguquka okukhulu nokunwebeka
- Ukumelana kangcono nokuhuzuka
– Izindleko eziphansi
Kodwa-ke, kukhona futhi okunye okungalungile ekusebenziseni i-TPE, okuhlanganisa:
– Amandla ezinyembezi angenamandla
– Ukungazweli kahle emazingeni okushisa aphezulu
– Izinketho zombala ezinomkhawulo
Ungakhetha kanjani phakathi kwerabha ye-silicone ne-TPE?
Uma udinga into ehlala isikhathi eside, ekwazi ukumelana nokushisa yephrojekthi yakho, ungase uzibuze ukuthi usebenzise irabha ye-silicone noma i-TPE (i-thermoplastic elastomer). Zombili izinto zokwakha zinezinzuzo kanye nokubi, ngakho-ke kubalulekile ukukhetha ezifanele izidingo zakho.
Nazi ezinye izinto okufanele uzicabangele lapho wenza isinqumo sakho:
- Lithini izinga lokushisa lephrojekthi yakho?
- Hlobo luni lwezakhiwo zemishini ozidingayo?
- Iliphi izinga lokumelana namakhemikhali olidingayo?
- Hlobo luni lobuhle olufunayo?
Isiphetho
Irabha ye-Silicone inezinzuzo eziningi eziyenza ilungele ukusetshenziswa okuhlukahlukene. Ihambisana kakhulu nomzimba womuntu kunezinye izinto, okwenza ilungele amashubhu emishini yezokwelapha. Iphinde imelane namazinga okushisa aphezulu, okuyenza ilungele ukusetshenziswa ezindaweni ezishisa kakhulu. Kodwa-ke, irabha ye-silicone ayiqinile njenge-TPE futhi ingase ingafaneleki izinhlelo zokusebenza ezidinga impilo ende.
