Silicone ke sesebelisoa sa maiketsetso se sebetsang ka bongata se sebelisoang mefuteng e mengata ea lits'ebetso ho liindasteri tse ngata.Silicone e ka fumanoa lihlahisoa tseo re li sebelisang bophelong ba rona ba letsatsi le letsatsi, ho tloha likoloing tseo re li khannang, ho lokisetsa lijo le lihlahisoa tsa polokelo, libotlolo tsa bana le li-pacifiers, le meno le lihlahisoa tse ling tsa letsatsi le letsatsi tsa bohloeki.Silicone e boetse e sebelisoa haholo lihlahisoa tse ka pholosang bophelo ba rona ho kenyelletsa limaske tsa phefumoloho, li-IV, le lisebelisoa tse ling tsa bohlokoa tsa bongaka le tsa bophelo bo botle. Sehloohong sena, re tšohla litšebeliso tsa eona le hore na e bapisoa joang le silicon le polasetiki.U tla ithuta ho eketsehileng ka mokhoa oa tlhahiso ea silicone le melemo e meng e hlokomelehang ea motsoako ona.

Silicone ke Eng?

Silicone, eo hape e tsejoang e le polysiloxane, ke thepa e entsoeng ke motho.Ke polymer e nang le siloxane e nang le sebopeho se kang rabara le limolek'hule tse nang le liketane tsa liathomo tsa oksijene le silicon tse fapanyetsanang.Polymer ena e ikhethang e ka ba karolo ea bohlokoa e sebelisoang ho:

• Li-resin
• Mekelikeli
• Li-elastomers

Phapang e khethollang pakeng tsa silicone le li-polymer tse ling tsa indasteri ke hore mokokotlo oa tsona oa molek'hule ha o na carbon.Tse ling tsa lisebelisoa tse tloaelehileng tse sebelisang silicone li kenyelletsa:

• Sekotlolo sa ho fepa ka silicone
• Brush ea litlolo tsa silicone
• Lisebelisoa tsa kichine
• O-rings
• Moalo o sa cheseng mocheso
• Silicone baby teether
• Mefuta e bonolo
• Lintho tsa ho bapala tsa silicone tsa thuto
• Li-gaskets
• Li-Silicone Collapsible Cups
• Ketlele ea ho phutha
• Silicone phoofolo ea lapeng
• Pacifier ea ho fepa bana

Liindasteri ho tloha ho tsa likoloi ho ea ho masela le bareki ho isa ho li-silicone tse sebelisang bongaka ka merero e fapaneng.

Silicone e entsoe ka Eng?

Joaloka polymer e sebetsang ka mokhoa o fapaneng, silicone e ka har'a tse latelang:

• Li-Caulks
• Lioli
• Li-elastomers
• Litlolo

Sejo se ka sehloohong sa silicone ke silica - e 'ngoe ea mefuta e tloaelehileng ea lehlabathe.Mona ke seo u hlokang ho se tseba ka silicone vs. silicon.

Silicone e Hlahisoa Joang?

A re hlahlobeng mehato e fapaneng e amehang tlhahisong ea silicone.

Mohato oa 1: Arola Silicon ho Silika

Ho arola silicon ho silika ke mohato oa pele oa ho hlahisa silicone.Ho finyella sena, palo e kholo ea lehlabathe la quartz e futhumatsoa ho mocheso oa likhato tse 1800 tsa Celsius.Sephetho se hloekileng, se ikemetseng ke silicon.Ha e se e pholile, bahlahisi ba ka e sila hore e be phofo e ntle.

Mohato oa 2: Kopanya phofo le Methyl Chloride

Phofo e ntle ea silicon e kopantsoe le methyl chloride.Ho sebelisa mocheso hape ho kenya tšebetsong karabelo lipakeng tsa likarolo tse etsang se tsejoang e le methyl chlorosilane.Methyl chlorosilane ke motsoako o nang le metsoako e mengata, e kholo ka ho fetisisa, dimethyldichlorosilane, ke mohaho o ka sehloohong oa silicone.

Mohato oa 3: Hlakola Motsoako

Ho tloha dimethyldichlorosilane ho silicone ho hloka ts'ebetso e rarahaneng ea distillation ho arola likarolo tse fapaneng tsa methyl chlorosilane ho tse ling.Kaha li-chlorosilane li na le libaka tse belang tse fapaneng, mohato ona o kenyelletsa ho futhumatsa motsoako letotong la mocheso o nepahetseng.

Mohato oa 4: Ho Eketsoa ha Metsi

Ho latela distillation, ho kopanya metsi le dimethyldichlorosilane ho baka karohano ea hydrochloric acid le disilanol. Hydrochloric acid ebe e sebetsa e le sesosa sa diquinone, e etsa hore e kopane ho polydimethylsiloxane.

Mohato oa 5: Polymerization ea Silicone

U tla hlokomela hore polydimethylsiloxane e na le bond ea siloxane.Kamano ena ke mokokotlo oa silicone.Polymerizing silicone e kenyelletsa mekhoa e mengata e fapaneng ho latela thepa e lakatsehang ea sehlahisoa se felileng. Le hoja ts'ebetso ea tlhahiso ea silicone e ka 'na ea bonahala e rarahane, ha e le hantle, e hlakile ebile e ka etsahala ka bongata bakeng sa litšenyehelo tse tlaase.Ka hona, ha ho makatse hore ebe silicone e sebetsang ka mokhoa o fapaneng e hlahile e le e 'ngoe ea li-elastomer tse tsebahalang haholo bakeng sa ts'ebeliso ea khoebo le indasteri.

Silicone vs. Plastiki

Plastiki le silicone ke lisebelisoa tse tšoarellang haholo le tse bonolo, 'me li ka ba le chebahalo le maikutlo a tšoanang.Le hoja tse peli li tšoana hantle, lik'hemik'hale le limolek'hule tsa tsona li etsa hore li fapane. Lipolasetiki li na le mokokotlo oa limolek'hule tse entsoeng ka carbon le hydrogen.Ho li hlahisa ho sebelisa lisebelisoa tse latelang:

• Khase ea tlhaho
• Limela
• Oli e tala

Lipolasetiki li entsoe ka lintho tse sa senyeheng tikolohong 'me li ka senyeha ho ba li-microplastic tse kotsi.Hape ka linako tse ling li na le chefo, joalo ka bisphenol A. Plastiki ha e tšoarelle nako e telele joalo ka li-silicone 'me ha e khone ho mamella mocheso o feteletseng.

Melemo ea Silicone

Lisebelisoa tsa silicone li molemo haholo bakeng sa lisebelisoa tse fapaneng.Ka lebaka la thepa ea eona, lisebelisoa tsa silicone li na le melemo e mengata, thepa ena e kenyelletsa tse latelang:

• Ho tenyetseha
• Malleability
• Ho hlaka
• Ho hanyetsa mocheso
• Ho hanyetsa metsi
• Ho kenella ha moea
• Ho tšoarella
• Ho bonolo ho hloekisa
• Sethupa
• E thibang letheba
• Khase e kenang haholo
• E nkang nako e telele
• Nontoxic
• E sa nkheng

Silicone e bonolo ho e etsa le ho bōptjoa 'me e tla ka mefuta e sa tšoaneng (metsi, e tiileng kapa ea lakane) ho itšetlehile ka mokhoa oa ho bōpa kapa oa ho etsoa le tšebeliso e khethehileng.Hore na kopo ea hau e hloka ho hanyetsa mocheso o moholo kapa ho fokola ho feta, baetsi ba thepa ba fana ka mefuta e fapaneng ea metsoako le limaraka ho fihlela litlhoko tsa hau tse fapaneng.
