Ukuba uyinto efana nam, uhlala ujonge iindlela zokuphucula izakhono zakho zokwenza. Kwaye enye yeendlela ezilungileyo zokwenza oko kukufunda ngezinto ezahlukeneyo kunye nendlela yokuzisebenzisa. Ke namhlanje, ndifuna ukuthelekisa izinto ezimbini ezidumileyo zokwenza izinto: irabha ye-silicone kunye ne-neoprene.
Intshayelelo: yintoni irabha ye-silicone kunye ne-neoprene?
I-rubber ye-silicone kunye ne-neoprene zizinto ezimbini ezisetyenziswa rhoqo kwiinkqubo ezahlukeneyo. Zombini izixhobo zineempawu zazo ezizodwa ezenza ukuba zilungele iinjongo ezahlukeneyo.
Irabha yeSilicone yirabha yokwenziwa eyenziwe ngesilicon, ioksijini, kunye nezinye izinto eziphilayo. I-rubber ye-silicone inoluhlu olubanzi lwezicelo ngenxa yokumelana nokushisa kunye nokubanda, kunye nokuguquguquka kwayo kunye nokuqina. I-rubber ye-Silicone inoluhlu olubanzi lwezicelo, kubandakanywa izitywina kunye ne-gaskets, ukugquma kombane, kunye nezixhobo zonyango.
I-Neoprene yirabha yokwenziwa eyenziwe nge-chloroprene. Yaqala ukuphuhliswa ngoo-1930 kwaye sele isetyenziswa kwiintlobo ngeentlobo zezicelo ezifana neempahla zokumanzisa, iigaskithi, kunye netywina. I-Neoprene iyaziwa ngokuxhathisa kwayo kwioli kunye neekhemikhali, kunye neempawu zayo zokugquma.
Iipropati: thelekisa iimpawu eziphambili zemathiriyeli nganye
Omnye umahluko ophambili phakathi kwerabha ye-silicone kunye ne-neoprene kukuba irabha ye-silicone inomgangatho ophezulu wokushisa kune-neoprene. INeoprene iyakwazi ukumelana namaqondo obushushu ukuya kutsho kuma-200°F, ngelixa irabha yesilicone inokumelana namaqondo obushushu ukuya kutsho kuma-500°F. Ukongeza, irabha ye-silicone ixhathisa ngakumbi kukukhanya kwe-UV kunye ne-ozone kune-neoprene.
I-Neoprene yirabha yokwenziwa eyaphuhliswa ngeminyaka yoo-1930. Isetyenziswa kwizicelo ezahlukeneyo, kubandakanya ii-wetsuits, imikhono yelaptop, kunye neepads zempuku. I-Neoprene inezinga eliphezulu lokumelana neekhemikhali kwaye ayithobi lula. Ikwamelana nobushushu nokubanda, oko kuyenza ibe yinto efanelekileyo kwizicelo ezininzi zangaphandle.
Irabha yeSilicone yenye irabha eyenziweyo eyaphuhliswa ekuqaleni kwenkulungwane yama-20. I-rubber ye-silicone inoluhlu olubanzi lwezicelo ngenxa yeempawu zayo ezizodwa. Irabha yeSilicone iyamelana nobushushu obugqithisileyo, ukukhanya kwe-UV, kunye neekhemikhali. Ikwanayo ne-coefficient ephantsi ye-friction, eyenza ilungele ukusetyenziswa kwii-seals kunye ne-gaskets.
Ziziphi iingenelo zerabha ye-silicone?
Irabha ye-Silicone ineempawu ezininzi ezenza kube lukhetho olubalaseleyo kwiintlobo ezahlukeneyo zezicelo, kubandakanywa ukumelana nobushushu obuphezulu, ukumelana nobushushu obuphantsi, ukugqunywa kombane, ukuxhathisa imichiza, kunye nokunyanzeliswa kwesethi yokunyanzeliswa.
Enye yeenzuzo eziphambili zerabha ye-silicone kukuchasana kwayo nobushushu obugqithisileyo. Ingasetyenziswa kwiindawo ukusuka kwi -55 ° C ukuya +300 ° C (-67 ° F ukuya ku-572 ° F), okwenza kube lukhetho olufanelekileyo kwiintlobo ezahlukeneyo zezicelo.
Irabha yeSilicone inokumelana okubalaseleyo kukukhanya kwe-UV, i-ozone, kunye neoksijini, iyenza ilungele ukusetyenziswa ngaphandle. Ikwamelana neekhemikhali, i-oyile, kunye negrisi, oko kuyenza ibe lukhetho oluhle kwizicelo apho ezi zinto zikhoyo.
Irabha yeSilicone ikwayinto enwebekayo kakhulu, nto leyo ethetha ukuba inokubuyela kubume bayo bokuqala nasemva kokuba yoluliwe okanye icinezelwe. Oku kuyenza ilungele izicelo apho kufuneka ubhetyebhetye.
Ekugqibeleni, irabha ye-silicone yinto ehambelana kakhulu nendalo. Ayina tyhefu kwaye inokuphinda isetyenziswe, iyenze ibe lukhetho olulungileyo lwezicelo apho ukuqwalaselwa kokusingqongileyo kubalulekile.
Ziziphi iingenelo ze-neoprene?
I-Neoprene inoluhlu olubanzi lwezicelo, kubandakanywa ukusetyenziswa njenge-padding kunye nokugquma kumashishini ahlukeneyo. Irabha yeNeoprene kukuxhathisa ubushushu, ioyile, kunye nokuqhawuka. Ikwamelana nokuthotywa kokukhanya kwelanga kunye nemozulu.
Kukho iingenelo ezininzi zokusebenzisa i-neoprene, kubandakanywa oku kulandelayo:
-Iyakwazi ukumelana neoli, iikhemikhali kunye nobushushu. Oku kuyenza ibe lolona khetho lufanelekileyo lokusetyenziswa kwizicelo ezininzi zamashishini.
-Ineempawu ezintle zokugquma, okwenza ukuba ibe luncedo kwi-padding kunye ne-insulation.
-Iyaguquguquka kwaye ikhululekile ukugqoka, okwenza kube yinto ethandwayo yokukhetha iimpahla ezifana ne-wetsuits.
-Kuyinto engabizi kakhulu ukuvelisa, okwenza kube yindlela engabizi kakhulu kwizicelo ezininzi.
I-rubber ye-silicone kunye ne-neoprene ithelekisa njani ngokweendleko?
Ngokweendleko, irabha ye-silicone idla ngokubiza kakhulu kune-neoprene. Nangona kunjalo, kukho ezinye izinto ezinokuchaphazela ixabiso, njengohlobo lwerabha ye-silicone kunye nobungakanani obufunekayo. Ngokomzekelo, irabha ye-silicone ye-medical-grade ingaba yindleko ngakumbi kune-rabha ye-silicone yenjongo jikelele. Ngokobungakanani, ukuthenga ngobuninzi kunokunciphisa iindleko zizonke ngeyunithi.
Yiyiphi eyona ingcono kwizicelo ezithile - irabha ye-silicone okanye i-neoprene?
Lo ngumbuzo onzima ukuwuphendula njengoko kuxhomekeke kwisicelo esithile okanye imfuno. Ngokubanzi, irabha ye-silicone inokumelana okungcono kumaqondo okushisa aphezulu kune-neoprene, okwenza kube yinto yokuqala yokukhetha izicelo apho ukuxhathisa ukushisa kubalulekile. Nangona kunjalo, irabha ye-neoprene inokumelana okungcono kumafutha kunye ne-oyile kunerabha ye-silicone, ngoko iya kuba yinto ekhethwayo kwizicelo apho zikhona. Ngokumalunga nokuchasana kweekhemikhali, zombini izinto zifana kakhulu - zombini zichasene nama-acids amaninzi kunye ne-alkali, kodwa akufanele zisetyenziswe kunye ne-solvents.
I-rubber ye-silicone kunye ne-neoprene ithelekisa njani ngokwempembelelo yendalo?
Ngokwempembelelo yokusingqongileyo, irabha ye-silicone kunye ne-neoprene zifana kakhulu. Zombini zenziwe ngezinto zokwenziwa, kwaye zombini azina-biodegradable. Nangona kunjalo, irabha ye-silicone ngokuqhelekileyo ithathwa njengento eco-friendly kune-neoprene.
Omnye umahluko omkhulu phakathi kwezi zibini kukuba irabha ye-silicone yenziwe kwi-silicon, into eyenzeka ngokwemvelo, ngelixa i-neoprene yenziwe kwiimveliso zepetroleum. Oku kwenza irabha ye-silicone ibe ngumthombo ohlaziyekayo ngakumbi. Ukongeza, irabha ye-silicone inokuphinda isetyenziswe, ngelixa i-neoprene ayikwazi.
Irabha ye-silicone nayo ayinakukwazi ukukhupha iikhemikhali eziyingozi kwindalo esingqongileyo. I-Neoprene inee-chlorofluorocarbons (CFCs), ezinokonakalisa umaleko we-ozone, kunye ne-polychlorinated biphenyls (PCBs), ezinokubangela iingxaki zempilo ebantwini nakwizilwanyana. Irabha yeSilicone ayinayo le michiza iyingozi.
Ngokubanzi, irabha ye-silicone lolona khetho lunobuhlobo ngakumbi kwezi zinto zimbini.
Yiyiphi enye omele uyikhethe - irabha ye-silicone okanye i-neoprene?
Impendulo yalo mbuzo ixhomekeke kwiziphi iimpawu ozixabisa kakhulu kwizinto zerabha. Irabha yeSilicone yaziwa ngokuxhathisa ubushushu, ngelixa i-neoprene isaziwa ngokumelana ne-oyile.Nantsi inkcazo ethe kratya yeempawu eziphambili zemathiriyeli nganye:
Irabha yeSilicone:
-Ukumelana nobushushu: Irabha yeSilicone inokumelana nobushushu ukuya kuthi ga kwi-500 ° F. Ezinje ukumelana nobushushu umcu werabha abicah.
