Kunezinhlobo eziningi ezahlukene zenjoloba emakethe namuhla, kodwa ezimbili ezidume kakhulu irabha ye-silicone ne-latex. Bobabili banesethi yabo eyingqayizivele yezakhiwo ezibenza bafanelekele izinhloso ezahlukene. Kulesi sihloko, sizoqhathanisa futhi siqhathanise lezi zinto ezimbili ngokwezakhiwo zazo ezingokomzimba namakhemikhali, kanye nezicelo zazo.
Isingeniso: yini irabha ye-silicone ne-latex?
Irabha ye-silicone ne-latex womabili ama-polymers, okusho ukuthi akhiwe ngamaketanga amade ama-molecule. Zombili ziyanwebeka, okusho ukuthi zinganwetshwa bese zibuyela esimweni sazo sokuqala. Irabha ye-Silicone iyi-polymer yokwenziwa eyenziwe nge-silicone, umoya-mpilo, nama-athomu e-hydrogen. I-Latex iyi-polymer yemvelo eyenziwe ngezinto ezitholakala ezitshalweni. Zombili zisetshenziswa emikhiqizweni edinga ukuguquguquka futhi ibe nezinga eliphezulu lokumelana nokushisa nokubanda. Nokho, kunomehluko oyinhloko phakathi kwalezi zinto ezimbili.
Irabha ye-Silicone yenziwe nge-silicone, i-polymer yokwenziwa. Inezinga eliphezulu lokumelana nokushisa kune-latex, okuyenza ifaneleke emikhiqizweni ezochayeka emazingeni okushisa aphezulu. Iphinde imelane namafutha namakhemikhali, okwenza ilungele ukusetshenziswa emishini yezokwelapha noma izimpawu ezidinga ukumelana nezimo ezinzima. Kodwa-ke, irabha ye-silicone ibiza kakhulu kune-latex.
I-latex yenziwe ngenjoloba yemvelo, ephuma emanzini ezihlahla ezithile. Ibizi kakhulu kunerabha ye-silicone kodwa ayimelani namazinga okushisa aphezulu noma amakhemikhali.
Uyini umehluko phakathi kwerabha ye-silicone ne-latex?
-Kokubili irabha ye-silicone ne-latex ama-polymer anwebekayo anezinhlelo eziningi zokusebenza.
-Irabha ye-Silicone yenziwe nge-silicon, into engokwemvelo etholakala esihlabathini nase-quartz. I-Latex ivela emithonjeni ehlukahlukene yemvelo efana nencindi yesihlahla nobisi. Ngenxa yalokho, irabha ye-silicone imelana nokushisa futhi ihlala isikhathi eside kune-latex.
-Irabha ye-Silicone iyirabha yokwenziwa futhi imelana namazinga okushisa aphakeme, ukukhanya kwe-UV, i-ozone, nokuwohloka kwamakhemikhali. I-Latex iyi-polymer yemvelo ekwazi ukuwohloka ngokuhamba kwesikhathi lapho ichayeke elangeni ne-ozone. Irabha ye-Silicone ayibhidliki kalula njenge-latex lapho ivezwe ekukhanyeni kwe-UV noma ezinye izakhi
-Irabha ye-Silicone ayihlangani nezinye izinto, kuyilapho i-latex ingabangela ukungezwani komzimba kwabanye abantu. Irabha ye-Silicone ngokuvamile ayiguli kakhulu kune-latex.
Izakhiwo zenjoloba ye-silicone: ukumelana nokushisa, ukumelana nesimo sezulu, ukufakwa kukagesi
Irabha ye-Silicone iyi-elastomer eyakhiwe nge-silicone-yona ngokwayo i-polymer-ne-oxygen. Amarabha e-Silicone asetshenziswa kakhulu embonini, futhi kukhona ukwakheka okuningi. Amarabha e-Silicone ayahlukahluka ngezakhiwo zawo ezingokomzimba namakhemikhali, anqunywa uhlobo lwamafutha abicah, i-agent exhumanisa iziphambano, izigcwalisi, nezithasiselo ezisetshenziswayo. Izakhiwo ezijwayelekile zamarabha we-silicone zihlanganisa:
-Ukumelana nokushisa: Amarabha e-Silicone angakwazi ukumelana namazinga okushisa asuka ku- -55 kuya ku-300 °C (−67 kuya ku-572 °F) kuyilapho egcina izakhiwo zawo eziwusizo. Imichilo yerabha ye-Silicone amelana nezinga lokushisa elidlulele, kokubili kushisa nokubanda, okuyenza ifaneleke ukusetshenziswa ezinhlobonhlobo zezilungiselelo.
-Ukumelana nesimo sezulu: Irabha ye-Silicone ayiwohloki lapho ichayeka elangeni noma isimo sezulu njengamanye ama-elastomer. Lesi sakhiwo sikwenza kube kuhle ezinhlelweni zangaphandle lapho ezinye izinto ezisetshenziswayo zizolulazeka ngokushesha. Ukumelana namanzi Nakuba irabha ye-silicone ingeyona into ekwazi ukumelana namanzi ngempela, ingamelana namazinga athile omswakama. A i-gasket yerabha ye-silicone ingasetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ezichayeka kumswakama ophezulu noma imvula.
-Ukufakwa kukagesi: Irabha ye-Silicone iyisivikeli esingcono kakhulu sikagesi. Inamandla aphezulu e-dielectric futhi ikwazi ukumelana nama-voltage aphezulu. Irabha ye-Silicone nayo ine-thermal conductivity ephansi, okwenza ifaneleke ukusetshenziswa ezinhlelweni zikagesi lapho ukuchithwa kokushisa kuwukukhathazeka. Irabha ye-Silicone nayo imelana ne-ozone kanye nemisebe ye-ultraviolet, iyenze ibe yinto ekahle yokusetshenziswa ngaphandle.
-Ingazweli emanzini namakhemikhali: Iphinde imelane namanzi namakhemikhali, okwenza ilungele ukusetshenziswa kwezokwelapha, ukudla nesiphuzo, kanye nasezimbonini zokusebenza. Irabha ye-Silicone nayo ayinabo ubuthi futhi ayi-hypoallergenic, iyenza iphephe ukusetshenziswa nesikhumba esibucayi.
Izici ze-latex: i-biodegradable, i-elasticity, iphephile futhi ihlala isikhathi eside
I-Latex iyimpahla ebolayo eyenziwe ngobisi lwezihlahla zenjoloba. Kuyinto yemvelo, ngakho-ke inezinzuzo ezithile zemvelo ngaphezu kwezinto zokwenziwa njenge-silicone.
I-Latex inwebeka kakhulu, okusho ukuthi inganwetshwa futhi ibuyiselwe esimweni sayo sasekuqaleni ngaphandle kokulimala. Lokhu kuyenza ilungele ukusetshenziswa ezinhlelweni eziningi, njengamagilavu, amakhondomu, namabhaluni. I-Latex iphinde imelane nokukhanya kwe-UV nomoya-mpilo, okuyenza iqine kakhulu kunezinye izinto.
I-Latex yinto esetshenziswe emikhiqizweni iminyaka eminingi. Yenziwe ngezithako zemvelo ngakho-ke i-biodegradable. Iphinde ibe yi-hypoallergenic, ngakho iphephile kubantu abane-latex allergies.
I-Latex nayo iqinile kakhulu futhi inokumelana okuphezulu nokuklebhuka.
Izingqinamba zenjoloba ye-silicone
Enye yezingqinamba eziyinhloko zerabha ye-silicone izindleko zayo. Irabha ye-Silicone ibiza kakhulu kunezinye izinhlobo zenjoloba, njengerabha yemvelo, irabha ye-neoprene nerabha ye-urethane.
Izingqinamba ze-latex
Nakuba i-latex inezinzuzo eziningi, kukhona futhi ezinye izithiyo ezingase zicatshangelwe. Isibonelo, i-latex ingabangela ukungezwani komzimba kwabanye abantu. Ngaphezu kwalokho, i-latex ayiboli futhi ngenxa yalokho akuyona inketho evumelana kakhulu nemvelo.
Ukusetshenziswa kwerabha ye-silicone: amadivaysi ezokwelapha, i-cookware, ama-sealants
Amashubhu enjoloba e-Silicone zisetshenziswa ezinhlobonhlobo zemishini yezokwelapha ngoba ayisebenzi, okusho ukuthi ayihlangani nomzimba noma ibangele ukwenqatshwa njengezinye izinto. Futhi iyakwazi ukuguquguquka futhi ingagcina isimo sayo ngokuhamba kwesikhathi, iyenze ilungele ukusetshenziswa isikhathi eside kuma-implants nama-prosthetics. Ukwengeza, irabha ye-silicone ayibhidliki lapho ibhekene noketshezi lomzimba noma amazinga okushisa aphezulu, okuyenza ifaneleke ukusetshenziswa kuzinto zokupheka nezinsimbi.
Ukusetshenziswa kwe-latex: amagilavu, amakhondomu, amabhaluni
Kuningi ukusetshenziswa kwamagilavu e-latex, amakhondomu namabhaluni. I-latex yinto etholakala emanzini ezihlahla zenjoloba. Kungumkhiqizo wemvelo ongaboli futhi we-hypoallergenic. Isetshenziswe amakhulu eminyaka ezinhlelweni eziningi ezahlukene.
Amagilavu e-latex avame ukusetshenziswa emkhakheni wezokwelapha, njengoba enikeza umgoqo phakathi kwesiguli nomnakekeli. Zibuye zisetshenziswe emsebenzini wokudla, njengoba zivikela ezifweni ezitholakala ekudleni. Amakhondomu enziwe nge-latex futhi asetshenziselwa ukuvimbela ukukhulelwa nokubhebhetheka kwezifo ezithathelwana ngocansi. Amabhaluni nawo enziwe nge-latex futhi avame ukusetshenziselwa ukuhlobisa noma njengezintandokazi zephathi.
I-Latex isetshenziswa ekwenzeni upende we-latex, usimende wenjoloba, neminye imikhiqizo yasendlini. I-Latex nayo ivame ukusetshenziswa embonini yezokwakha, njengoba ingasetshenziswa ukudala ama-sealants avimbela isimo sezulu kanye nama-adhesives.
Isiphetho
Kunezinhlobo eziningi ezahlukene zenjoloba emakethe, ngayinye inesethi yayo yezinzuzo kanye nezithiyo. Endabeni yerabha ye-silicone vs i-latex, kuyacaca ukuthi irabha ye-silicone inezinzuzo eziningana ngaphezu kwe-latex. Irabha ye-Silicone ihlala isikhathi eside, inokumelana nokushisa okuphezulu, futhi mancane amathuba okuba ibangele ukungezwani ne-latex. Kodwa-ke, i-latex ivamise ukubiza kancane kunerabha ye-silicone, futhi ingase ibe ukukhetha okungcono kwezinhlelo zokusebenza lapho ukuguquguquka nokunwebeka kubaluleke kakhulu kunokuqina.
