Silicones ikirasi inosiyana-siyana yemapolymers anouya nenzira dzakasiyana-siyana, achipa mukana wakakura wekugadzirisa kuti usangane nezvinodiwa chaizvo zvezvekurapa uye zvemuchadenga zvikamu.Hunhu hwavo hunovagonesa kuita mabasa akasiyana-siyana, akadai sekuisa chisimbiso, kuzora mafuta, uye kuita mamwe mabasa akawanda.
Silicone's versatility inoratidzwa kune yayo yakasarudzika yemuviri uye michina zvimiro, izvo zvinoita kuti ive yakakosha zvinhu mumaindasitiri akasiyana.Ichi chinyorwa chichaongorora mukati Zvishanu zvakajairika zvivakwa uyesilicone inobatsirauye kuongororamapoka mana ekutangayesilicone zvinhu.Pamusoro pezvo, isu tichakurukura nzira dzakasiyana dzekugadzira uye kutsanangura kuti sei silicone ingave sarudzo yakakodzera kune zvaunoda chaizvo.
1.Silicones haigadziri makemikari uye inoratidza hurombo husina kunaka hwekupisa.
Kutyora silicon-oxygen cheni mumamorekuru esilicone kunoda huwandu hwakakosha hwesimba.Nekuda kwekupikiswa kwakanyanya kwesilicone mamorekuru kuti achinje, makemikari mazhinji haana simba rakakwana rekukurudzira kuita kwemakemikari.Nekuda kweizvozvo, silicone kazhinji isiri-reactive kemikari.Iyo yakagadzika zvisungo musilicone inokonzeresa kune akawanda ayo akanaka maitiro.
MaSilicones anowanzo ratidza yakaderera kupisa conductivity nekuda kweiyo molecular chimiro, izvo zvinotadzisa kupararira kwekudziya kwekushisa pakati pemamorekuru.Nepo ichi chivakwa chingave chakanakira mune mamwe maapplication, senge oven mitts, inogona kuve mhedziso mune mamwe mamiriro apo kufambiswa kwekushisa kwakanaka kunodiwa.Kugadzirisa nyaya iyi, thermally conductive fillers inogona kuisirwa mune iyo silicone kuumbwa kuti iwedzere kupisa kutamisa uye kusangana nezvinodiwa zvechinangwa chekushandisa.
2.Silicone ine yakaderera chepfu
Silicone inowanzoonekwa sechinhu chisingakuvadzi kune hutano hwevanhu.Ese ari maviri echikafu-giredhi uye ekurapa-giredhi silicone makomisheni akabvumidzwa neFDA kuti ashandiswe mukusangana kwechikafu uye kuisirwa kwenguva refu mumuviri wemunhu.Zvakadaro, ndapota zvakakosha kutevedzera nhungamiro yemugadziri paunenge uchishandisa zvigadzirwa zvesilicone kuve nechokwadi chekuchengetedza kwakanyanya.
3.Silicone ine simba guru rekudzinga mvura
Silicone ine yakasarudzika mhando inozivikanwa se hydrophobicity, zvichireva kuti ine innate kugona kudzinga mvura.Izvi zvinoverengerwa kumapoka emethyl akabatanidzwa kune silicon-oxygen polymer cheni, ayo asiri-polar muzvisikwa uye asina hukama hwemvura mamorekuru.Nekuda kweizvozvo, mamorekuru emvura haakwanise kupararira uye kupinda mukati meiyo silicone, uye panzvimbo pacho, anonamira kumusoro uye anokunguruka.Ichi chinoshamisa chinodzinga mvura chivakwa, chakasanganiswa nekugona kwesilicone kugadzira chisungo chakasimba chekunamira chine nzvimbo dzakasiyana siyana, inoita kuti zvigadzirwa zvekuisa chisimbiso zvesilicone zvive zvakanyanya kushanda, zvine zvisimbiso zvinogara kwemakumi emakore.
4.Silicone inogona kuita se insulator uye conductor yemagetsi.
Silicone rabha rinowanzoita sechidziviriro nekuda kwekushaikwa kwayo kwemahara maerekitironi ekutakura machaji.Hunhu uhwu hunobatsira zvakanyanya pakushandisa kwakasiyana, kunyanya mukati memunda wekurapa uko kuvharisa kwakakosha.Nekudaro, silicone inogona kugadziridzwa kuti iite magetsi kune imwe nhanho yekushandisa senge gaskets uye static nhovo.Kugadziridzwa uku kunosanganisira kubatanidza mafirita akadai sekabhoni, sirivheri, kana zvimwe zvinoitisa zvinhu musilicone zvinhu.
5.Silicone ine kupikisa kwepamusoro kune organic compound solvents
Silicone inowanzo kwanisa kumira kuratidzwa kune akawanda makemikari nekuda kwekusagadzikana kwayo kuumbwa uye kushoma kwesimba repamusoro.Zvakangodaro, zvakasarudzwa zvishoma zvisingaite zvinhu, kunyanya zvakanyura sulfuric uye hydrofluoric acid, zvinogona kukuvadza silicones.Nezve organic komisheni inogona kushanda se sol, silicones inongotadza kuparara mushure mekusangana kwenguva refu nezvinhu zvakaita se toluene, mineral spirit, peturu, uye kabhoni tetrachloride.
Silicone inobatsira
Silicone's versatility inoita kuti ive chinhu chakakosha kune akasiyana maindasitiri, kusanganisira:
* Automotive: Silicone yakanyanya kupisa kupisa uye kusimba kunoita kuti ive chinhu chakanakira mukugadzira mota.
* Aerospace: Silicone yakanakisa insulation zvivakwa uye kuramba kune tembiricha yakanyanyisa inoita kuti ive chinhu chakakosha mukugadzirwa kwendege.
* Coatings: Silicone-based coatings inopa kugarisa uye kusapinda mvura kupera kweakasiyana siyana.
* Kuvaka: Silicone sealants uye zvinonamira zvinoshandiswa mukuvaka zvivakwa kuti ive nechokwadi chemhepo uye isina mvura majoini.
* Cookware: Silicone inodzivirira kupisa zvinhu inoita kuti ive chinhu chakanakisa chemidziyo yekubikira, senge mabheki uye spatula.
* Mafuta ekuzora: Silicone lubricant anoshandiswa mukushandisa kwakasiyana, kusanganisira injini dzemotokari, muchina weindasitiri, uye midziyo yemumba.
* Zvemagetsi: Silicone yakanakisa yekuvharisa zvivakwa inoita kuti ive chinhu chakakosha mumidziyo yemagetsi, senge makomputa, mafoni, uye terevhizheni.
* Kugadzira mold: Silicone kuchinjika uye kurongeka kunoita kuti ive chinhu chakanakira kugadzira molds yeakasiyana maapplication, kusanganisira ezvokurapa uye zvikamu zvemotokari.
* Mushonga uye kuvhiyiwa kwekunatsiridza: Silicone's biocompatibility uye versatility inoita kuti ive chinhu chakakosha mukuiswa kwekurapa, prosthetics, uye kuvhiyiwa kwekunatsa.
* Matoyi uye zvekuvaraidza: Silicone kuchinjika uye kusimba kunoita kuti ive yakakurumbira zvinhu zvekugadzira matoyi, mitambo, uye zvimwe zvinhu zvekuvaraidza.
Mhando dzekutanga dzeSilicone
Iwo mana makuru emuviri mhando kana mafomu esilicone zvigadzirwa akanyorwa pazasi:
• Room-temperature Vulcanizing (RTV): Aya silicones anorapa, kana kuisa, patembiricha yepakamuri.Iwo anowanzo shandiswa pakuisa chisimbiso uye kubatanidza.RTV-1 magadzirirwo anotanga kurapa nekukurumidza kana asangana nehunyoro mumhepo.RTV-2 silicones inouya semakomisheni maviri akapatsanurwa ayo mushandisi wekupedzisira anofanira kusanganisa kuti atange kurapa.Izvi zvinoita kuti RTV-2 iwedzere kuchinjika kune zvikumbiro senge kuumba uye kupeta.
• Liquid Silicone Rubber (LSR): LSR inoumbwa nemaitiro maviri-chikamu, pamwe chete nemakemikari maviri akabatanidzwa panguva yekushandiswa.Kazhinji inorapwa pakupisa kwepamusoro, uchishandisa platinum catalyst.Ose ari maviri maitiro ekuumba anoshandiswa uye ekupedzisira chigadzirwa maitiro eLSR anochinjika kune yakafara mhando yemashandisirwo.
• Fluorosilicone Rubber (FSR): FSR molecules inosanganisira kudzokorora zvikamu zvesilicon-oxygen backbone nedzimwe nzvimbo dzekubatanidza dzinogarwa nemamwe mapoka emamorekuru (methyl uye fluoroalkyl groups).Izvi zvinopa zvinhu zviri nani kupikisa mafuta nemafuta.FSR yakakurumbira pakuisa chisimbiso maapplication mumagadzirirwo endege.
• High-Consistency Rubber (HCR): HCR, inozivikanwawo se "heat-curing rubber," ine yakakwirira kwazvo molecular weight silicone polymer cheni.Iyo mbishi zvinhu inogona kugarisa mafirita uye ekuwedzera kuti awane anodiwa maitiro.Inowanzo gadzirirwa mune imwe nzira yakarapwa, yakati "gummy" fomu yakamonerwa mubepa gobvu.Yakanakira kushandiswa mune zvimwe zvigadzirwa zvekurapa, zvinosanganisira tubing, mabharumu, uye mashiti.
Silicone inouya munzvimbo dzakasiyana dzemuviri, kubva pamvura kusvika kune yakasimba.Customer inogona kugadzirisa akasiyana mhando silicone zvinoenderana nehunhu hwechigadzirwa kuti ienderane nezvinodiwa zvekupedzisira zvigadzirwa.
Summary
Chinyorwa chacho chakaongorora 5 hunhu hwesilicone, yakavhenekera makemikari ayo uye emuviri zvimiro, uye yakaongorora akasiyana siyana aanogona kutora mumaindasitiri ekushandisa.
Kuti udzidze zvakawanda nezve silicone,ndapota taura nesu.
