Nhanganyaya: Chii chinonzi silicone rabha?
Silicone rabha irabha rekugadzira rakagadzirwa kubva kusilicon uye oksijeni. Inoshandiswa mumhando dzakasiyana-siyana dzekushandisa, kusanganisira zvisimbiso, gaskets, hoses, mishonga yezvokurapa, uye magetsi ekudzivirira. Iyo ine yakanakisa kupisa kupisa uye inogona kushandiswa mune yakakwirira-tembiricha application. Silicone rabha zvakare inopesana nemakemikari akawanda uye zvinonyungudutsa. Inoshandiswa mune zvakasiyana-siyana zvekushandisa zvinosanganisira zvekurapa maimplants, lubricant, uye sealants.
Silicone Rubber Material: Mavambo uye Kuumbwa
Silicone Rubber Material irabha rekugadzira rine akawanda maapplication. Yakatanga kugadzirwa neDow Chemical Company muna 1946. Nyaya yacho inoumbwa nesilicon uye oksijeni uye inert, zvinoreva kuti haiiti nezvimwe zvinhu. Izvi zvinoita kuti ive yakakodzera kushandiswa mumaindasitiri akasiyana siyana, anosanganisira ekurapa, emotokari, uye aerospace. Silicone rabha inoshandiswa mumhando dzakasiyana-siyana dzekushandisa, kusanganisira: iphone 4s makesi nemakesi efoni, dashboards emota, midziyo yekumisasa, makonzo emakombuta uye kiibhodhi, midziyo yemitambo, midziyo yekurapa uye midziyo nezvimwe. Silicone rabha inoshandiswawo mumaindasitiri ekushandisa kwezvakasiyana zvigadzirwa zvinosanganisira hose, mabhandi ekutakurisa uye mavharuvhu. Silicone rabha ine zvakasiyana-siyana zvekushandisa uye zvivakwa. Inogona kuumbwa mumhando dzakasiyana uye ine yakanaka abrasion resistance.
Kugadzira Maitiro eSilicone Rubber
Silicone rabha inowanzoshandiswa mumidziyo yekurapa, kurongedza chikafu, uye matoyi evana nekuti haina chepfu uye inodzivirira kupisa. Nzira yekugadzira yesilicone rubber inotanga nekugadzirwa kwe silanes, iyo inosanganiswa nesilicon uye hydrogen. Aya silane anobva abatwa neklorini kuita machlorosilanes. Ma chlorosilanes anobva aitwa neoxygen kuita silicone rabha. Silicone rabha ipurasitiki ye thermoset, zvichireva kuti inoumba network-yakabatana network yepolymer cheni (polymer cheni macheni marefu emamorekuru akabatanidzwa pamwechete nemakemikari bond). Silicone rabha haina chepfu uye inodzivirira kupisa. Iyo mikuru masosi ehuchetura ndiwo mafuta esilicone anoshandiswa kuigadzira, pamwe neguruva resilicon rinoshandiswa mukusika kwayo. Siloxanes haina muchetura kupfuura mafuta esilicone uye haiburitse zvidimbu zvidiki mumhepo.
Zvivakwa zveSilicone Rubber
Silicone rabha inogadzirwa nekuita polymerizing zvinhu silicon uye okisijeni mumakemikari maitiro anonzi polycondensation. Polymerization inoitika kana huwandu hwakakosha hwesimba huchiiswa kune reactants uye inogadzira makemikari akasungwa mamorekuru. Iine zvinhu zvakawanda zvinoita kuti ive yakanakira zvinhu zvakasiyana-siyana zvekushandisa. Silicone rabha inoshingirira kupisa, ichiita kuti ive yakakodzera kushandiswa mukupisa kwepamusoro-soro senge cookware, bakeware, uye zvikamu zvemotokari. Iyo zvakare isiri-chepfu uye isiri-allergenic, ichiita kuti ive yakachengeteka kushandiswa mukusangana nechikafu kana ganda. Silicone rabha zvakare yakanyanyisa elastic, ichiita kuti ive yakanakira kushandiswa mumagaskets, zvisimbiso, uye zvimwe zvekuisa chisimbiso. Chekupedzisira, silicone rabha hainyunguriki mune zvinonyungudutsa zvakajairika, zvichiita kuti irambe ichidzikira kubva kune zvakatipoteredza zvinhu.
Zvishandiso zveSilicone Rubber
Silicone rabha ndeyekugadzira polymer ine akawanda maapplication. Inowanzoshandiswa mumishonga yezvokurapa, nokuti haisi-chepfu uye inogona kumira kemikari. Silicone rubber inogonawo kushandiswa kugadzira zvisimbiso uye gaskets, nokuti inoshanduka uye inopikisa kune zvose mafuta nemvura. Pamusoro pezvo, silicone rabha inogona kushandiswa seyekupfekedza waya yemagetsi, nekuti inodzivirira kupisa uye inodzivirira moto.
Mhedziso yeSilicone Rubber
Silicone rabha ine zvakawanda zvakanaka pamusoro pechinyakare rabha. Inonyanya kushanduka, uye inogona kutambanudzwa mberi pasina kutyora. Izvi zvinoita kuti ive yakakodzera kushandiswa mune zvigadzirwa zvinoda kukotama kana kutambanudza, senge hose uye zvisimbiso. Silicone zvakare haina mukana wekubvarura kana kubvarura, zvichiita kuti ive sarudzo iri nani kune zvigadzirwa zvinoiswa pasi pekupfeka uye kubvaruka. Mukuwedzera, silicone haina-chepfu uye inodzivirira kupisa, zvichiita kuti ive sarudzo yakachengeteka kune zvigadzirwa zvinosangana nechikafu kana kupisa. Kana uine chero mibvunzo, ndapota siyai meseji kwatiri.
