Ukuba ujonge into ehlala ixesha elide, ehlala ixesha elide kwiprojekthi yakho elandelayo, unokuzibuza ukuba ingaba irabha ye-silicone okanye i-tpe lukhetho olufanelekileyo. Zombini izixhobo zineenzuzo kunye nezinto ezisilela kuzo, ngoko ke kubalulekile ukuvavanya ngononophelo ukhetho lwakho ngaphambi kokuba wenze isigqibo. Nalu ushwankathelo olukhawulezayo lwemathiriyeli nganye ukukunceda wenze ukhetho olunolwazi.
Yintoni irabha ye-silicone kunye ne-TPE?
Irabha ye-silicone kunye ne-TPE zombini zi-elastomers, oku kuthetha ukuba zizinto ezifana nerabha ezinokubunjwa kunye nokubunjwa. Zombini zisetyenziswa kwiinkqubo ezahlukeneyo, ukusuka kwi-cookware ukuya kwiimeko zefowuni ukuya kwizixhobo zonyango.
Ke, yintoni umahluko phakathi kwerabha ye-silicone kunye ne-TPE? Irabha ye-Silicone yenziwe nge-silicone, i-polymer yokwenziwa. I-TPE yenziwe nge-thermoplastic elastomers, eyindibaniselwano yeeplastiki kunye neerabha.
Yintoni umahluko ophambili phakathi kwerabha abicah kunye TPE?
Kukho iiyantlukwano eziphambili phakathi kwerabha ye-silicone kunye ne-TPE. Irabha ye-Silicone yirabha yokwenziwa eyenziwe kwi-silicone, ngelixa i-TPE yi-elastomer ye-thermoplastic. Irabha ye-Silicone inokumelana nobushushu obuhle kunye nokumelana nemozulu, ngelixa i-TPE ingenayo. Irabha yeSilicone nayo ibiza kakhulu kuneTPE.
Ziziphi iingenelo kunye nokungalunganga kwerabha ye-silicone?
Kukho iintlobo ezininzi ezahlukeneyo zemathiriyeli yepolymer ekhoyo kwimarike namhlanje, nganye ineseti yayo eyahlukileyo yeepropathi kunye nokusetyenziswa kwayo. Izinto ezimbini ezidumileyo ezisetyenziswa kumashishini ahlukeneyo yirubha ye-silicone kunye ne-thermoplastic elastomers (TPE). Ukuze uqonde ukuba yeyiphi imathiriyeli eyona ilungele iimfuno zakho, kubalulekile ukuqonda umahluko ophambili phakathi kwezi polima zimbini.
Irabha yeSilicone yirabha yokwenziwa kwe-inorganic eyenziwe ngeeathom ze-silicone kunye ne-oxygen. Esi sixhobo saziwa ngokuxhathisa ubushushu obugqithisileyo, ukukhanya kwe-UV, i-ozone, kunye neoksijini. Ukongeza, irabha ye-silicone inokumelana okugqwesileyo kumanzi kunye nokufuma, iyenza ilungele ukusetyenziswa kwizicelo apho ukudibana namanzi kunokwenzeka. Enye i-downside ye-rubber ye-silicone kukuba ingaba nexabiso xa kuthelekiswa nezinye iipolymers.
I-Thermoplastic elastomers (TPE) luhlobo lwemathiriyeli ye-copolymer ebonisa zombini iimpawu ze-thermoplastic kunye ne-elastomeric. Ii-TPE zinokubunjwa kwaye zenziwe njenge-thermoplastics, kodwa zine-elasticity yeerubha. Oku kwenza ukuba ii-TPE zibe lolona khetho lufanelekileyo lwezicelo ezifuna ukuguquguquka kunye nokuqina. Ii-TPE zifumaneka kuluhlu olubanzi lwamanqanaba obunzima, okwenza ukuba zilungele yonke into ukusuka kwizinto zokudlala ezithambileyo ukuya kwiimeko zeqokobhe elilukhuni. Nangona kunjalo, ii-TPEs kunokuba nzima ukuphinda zisetyenziswe ngenxa yobume bazo obuxutyiweyo.
Ziziphi iingenelo kunye nokungalunganga kwe-TPE?
I-TPE yiklasi ye-thermoplastic elastomers equlethe zombini iipropathi zerabha kunye neplastiki. Iimveliso ze-TPE zineenzuzo ezininzi ngaphezu kweemveliso zerabha zemveli. Zihlala ixesha elide ngakumbi, kunye nokukrazula okukhulu kunye nokuxhathisa ukukrazula. Bakwaxhathisa uninzi lweeoyile, iikhemikhali, ukukhanya kwe-UV kunye nokutshintsha kobushushu obugqithisileyo kunerabha. Ii-TPE ziyanyibilika kwaye zigeleze njengeplastiki, ukuze zifakwe inaliti okanye zikhutshwe ngobude obuqhubekayo njengetyhubhu yerabha. Kwaye, njengerabha, ii-TPE zinokubunjwa phantse kuyo nayiphi na imilo onokucinga ngayo.
Eyona nto ingathandekiyo yee-TPE kukuzinza kwazo okuphantsi kwe-thermal xa kuthelekiswa nezinye ii-elastomers. Zinokuba brittle kumaqondo aphantsi kwaye zinokwehla kumaqondo aphezulu. Oku kugabadela kobushushu kunokubangela ukuba iindawo zijike okanye zijike.
Yiyiphi irabha ye-silicone yolona khetho lufanelekileyo?
Nangona zombini i-TPE kunye ne-silicone irabha ilukhetho oluhle kakhulu kwiinkqubo ezahlukeneyo, kukho iimeko ezithile apho irabha ye-silicone ilolona khetho lungcono.
Ukuba ufuna into enokumelana nokushisa okuphezulu, irabha ye-silicone yindlela yokuhamba. Inokumelana namaqondo obushushu ukuya kuthi ga kwi-400 degrees Celsius, iyenze ilungele izicelo apho ukumelana nobushushu kungundoqo.
Ukongeza, irabha ye-silicone inokumelana okugqwesileyo kukukhanya kwe-UV kunye ne-ozone, iyenza ibe lukhetho oluhle kwizicelo zangaphandle. Okokugqibela, irabha ye-silicone ineepropati ezinkulu zokugquma umbane, iyenza ilungele ukusetyenziswa kuyo amacandelo ombane kunye nephepha lezixhobo.
Yiyiphi i-TPE yolona khetho lungcono?
I-TPE ibonelela ngenani leenzuzo ngaphezulu kwerabha ye-silicone, kubandakanya:
-Ukuchasana ngcono kwi-UV kunye ne-ozonation
-Ukuguquguquka okukhulu kunye nokunwebeka
– Ngcono ukumelana nokuqhawuka
– Iindleko eziphantsi
Nangona kunjalo, kukwakho nezinye izinto ezingeloncedo ekusebenziseni i-TPE, kubandakanya:
– Amandla eenyembezi angenamandla
– Ukumelana kakubi namaqondo obushushu aphezulu
– Ukhetho lombala olulinganiselweyo
Unokukhetha njani phakathi kwerabha ye-silicone kunye ne-TPE?
Ukuba ufuna into ehlala ixesha elide, into ekwaziyo ukumelana nobushushu kwiprojekthi yakho, usenokuba uyazibuza ukuba usebenzisa irabha ye-silicone okanye i-TPE (i-thermoplastic elastomer). Zombini izixhobo zineengenelo kunye nezingeloncedo zazo, ngoko ke kubalulekile ukukhetha eyona ilungileyo kwiimfuno zakho.
Nazi ezinye izinto ekufuneka uziqwalasele xa usenza isigqibo:
- Luthini ubushushu beprojekthi yakho?
- Loluphi uhlobo lweempawu zoomatshini ozifunayo?
- Leliphi inqanaba lokuxhathisa imichiza oyifunayo?
- Loluphi uhlobo lobuhle olufunayo?
isiphelo
