I-Silicone yimathiriyeli eyenziwe ngeendlela ezininzi esetyenziswa kuluhlu oluninzi lwezicelo kuwo wonke amashishini amaninzi.I-Silicone inokufumaneka kwiimveliso esizisebenzisayo kubomi bethu bemihla ngemihla, ukusuka kwiimoto esiziqhubayo, ukulungiswa kokutya kunye neemveliso zokugcina, iibhotile zeentsana kunye ne-pacifiers, kunye namazinyo kunye nezinye iimveliso zococeko lwemihla ngemihla.I-Silicone ikwasetyenziswa ngokubanzi kwiimveliso ezinokusindisa ubomi bethu kubandakanya imaski yokuphefumla, ii-IV, kunye nezinye izixhobo ezibalulekileyo zonyango kunye nezempilo. Kweli nqaku, sixoxa ngokusetyenziswa kwayo kunye nendlela ethelekisa ngayo ne-silicon kunye neplastiki.Uya kufunda ngakumbi malunga nenkqubo yokuvelisa i-silicone kunye nezinye zeenzuzo eziphawulekayo zale khompawundi.

Yintoni iSilicone?

I-silicone, ekwabizwa ngokuba yi-polysiloxane, yimathiriyeli eyenziwe ngumntu.Yipolymer eyenziwe nge-siloxane ebonisa ukuhambelana okufana nerabha kunye neeathom ze-silicon.Le polymer yahlukileyo inokuba yinxalenye ephambili esetyenziswa ku:

  • Iintlaka
  • Ulwelo
  • Iielastomers

Umahluko ohlukileyo phakathi kwe-silicone kunye nezinye iipolymers zamashishini kukuba i-molecular backbone yabo ayinayo i-carbon.Ezinye zezicelo eziqhelekileyo zisebenzisa i-silicone ziquka:

Amashishini asusela kwiimoto ukuya kwizinto ezilukiweyo kunye nomthengi ukuya kusetyenziso lwe-silicone yonyango ngeenjongo ezahlukeneyo.

Yenziwe Ngantoni ISilicone?

Njengepolymer eguquguqukayo, i-silicone ikulandelayo:

  • IiCaulks
  • Iioli
  • Iielastomers
  • Iigrisi

Isithako esiphambili kwi-silicone yi-silica - enye yezona ndlela zixhaphakileyo zesanti.Nantsi into ekufuneka uyazi malunga ne-silicone vs.

Iveliswa njani iSilicone?

Makhe sihlolisise amanyathelo ahlukeneyo abandakanyekayo kwimveliso ye-silicone.

Inyathelo 1: Yahlula iSilicon kwiSilica

Ukwahlula i-silicon kwi-silica linyathelo lokuqala ekuveliseni i-silicone.Ukufezekisa oku, umthamo omkhulu wesanti yequartz ufudunyezwa kumaqondo obushushu afikelela kuma-1800 degrees Celsius.I-silicon ecocekileyo, eyodwa isiphumo.Yakuba ipholile, abavelisi banokuyicola ibe ngumgubo ocolekileyo.

Inyathelo lesi-2: Dibanisa iPowder kunye neMethyl Chloride

Umgubo ocolekileyo wesilicon uxutywe nemethyl chloride.Ukusebenzisa ubushushu kwakhona kuvula ukusabela phakathi kwamalungu enza into eyaziwa ngokuba yi-methyl chlorosilane.I-Methyl chlorosilane ngumxube oqulethe iikhompawundi ezininzi, eyona nto iphambili kuyo, i-dimethyldichlorosilane, iyona nto isisiseko sokwakha i-silicone.

Inyathelo lesi-3: Distill umxube

Ukufumana kwi-dimethyldichlorosilane ukuya kwi-silicone kufuna inkqubo entsonkothileyo yokuhluza ukwahlula amacandelo ahlukeneyo e-methyl chlorosilane omnye komnye.Ngenxa yokuba ii-chlorosilanes zineendawo zokubilisa ezahlukileyo, eli nyathelo libandakanya ukufudumeza umxube kuthotho lwamaqondo obushushu achanekileyo.

Inyathelo lesi-4: Ukongezwa kwaManzi

Ukulandela i-distillation, ukudibanisa amanzi kunye ne-dimethyldichlorosilane kubangela ukuhlukana kwe-hydrochloric acid kunye ne-disilanol. I-hydrochloric acid ke isebenza njenge-catalyst ye-diquinone, ibangela ukuba idibanise kwi-polydimethylsiloxane.

Inyathelo lesi-5: Ipolymerization yeSilicone

Uyakuqaphela i-polydimethylsiloxane inebhondi ye-siloxane.Le bhondi ngumqolo we-silicone.I-silicone yepolymerizing ibandakanya iindlela ezininzi ezahlukeneyo ngokuxhomekeke kwiipropathi ezinqwenelekayo zemveliso. Ngelixa inkqubo yokuvelisa abicah ingabonakala intsonkothile, eneneni, ithe ngqo kwaye inokuthi yenzeke kwisikali sobunzima ngexabiso eliphantsi.Ke ngoko, ayimangalisi into yokuba i-silicone eguquguqukayo iye yavela njengenye yezona zinto zidumileyo zokusebenzisa i-elastomers kurhwebo nakwimizi-mveliso.

I-Silicone vs. Iplastiki

Iplastiki kunye ne-silicone zizinto ezihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zidanje.Ngelixa ezi zimbini zifana ngokusondeleyo, imichiza yazo eyahlukileyo kunye neemolekyuli zizenza zahluke. Iiplastiki zine-molecular backbone eyenziwe ngekhabhoni kunye ne-hydrogen.Ukuzivelisa kusebenzisa ezi zixhobo zilandelayo:

  • Irhasi yendalo
  • Izityalo
  • I-oyile endala

Iiplastiki zenziwe ngezinto ezingaphantsi kokusingqongileyo kwaye zinokuqhekeka zibe yi-microplastics eyingozi.Ngamanye amaxesha ziqulethe i-toxins, efana ne-bisphenol A. Iiplastiki azihlali ixesha elide njenge-silicone kwaye azikwazi ukumelana nobushushu obugqithisileyo.

Iinzuzo zeSilicone

Izinto zeSilicone ziluncedo kakhulu kwiintlobo ezahlukeneyo zezicelo.Ngenxa yeepropati zayo, izinto ze-silicone zineenzuzo ezininzi, ezi mpawu ziquka oku kulandelayo:

  • Ukuba bhetyebhetye
  • Ukuba buthathaka
  • Ukucaca
  • Ukumelana nobushushu
  • Ukumelana namanzi
  • Ukungena komoya
  • Ukuqina
  • Kulula ukucoca
  • Ukungancamathiseli
  • Ukumelana namabala
  • Irhasi ephezulu enokungeneka
  • Ihlala ixesha elide
  • Ayinatyhefu
  • Ayinavumba

I-Silicone kulula ukwenza ngokwezifiso kunye nokubumba kwaye iza ngeendlela ezahlukeneyo (ulwelo, oluqinileyo okanye ishidi) kuxhomekeke kwindlela yokubumba okanye yokwenza kunye nokusetyenziswa okuthe ngqo.Nokuba isicelo sakho sifuna ukuxhathisa ubushushu okanye ukonakala okungaphezulu, abavelisi bezinto eziphathekayo babonelela ngeendlela ezahlukeneyo zekhompawundi kunye namabanga ukuhlangabezana neemfuno zakho ezahlukeneyo.
