Kana iwe uri chero seni, iwe unogara uchitsvaga nzira dzekuvandudza hunyanzvi hwako hwekugadzira. Uye imwe yedzakanakisa nzira dzekuita izvozvo kudzidza nezve akasiyana zvinhu uye mashandisiro azvo. Saka nhasi, ndinoda kuenzanisa zvinhu zviviri zvakakurumbira zvekugadzira: silicone rabha uye neoprene.
Nhanganyaya: chii chinonzi silicone rabha uye neoprene?
Silicone rubber uye neoprene zvinhu zviviri zvinowanzoshandiswa mumhando dzakasiyana-siyana dzekushandisa. Zvese zviri zviviri zvinhu zvine zvazvo zvakasiyana zvimiro zvinoita kuti zvikodzere zvinangwa zvakasiyana.
Silicone rabha irabha rekugadzira rinogadzirwa kubva kusilicon, okisijeni, uye mamwe organic komisheni. Silicone rubber ine huwandu hwakawanda hwekushandisa nekuda kwekupikisa kwayo kwakanyanya kupisa uye kutonhora, pamwe nekushanduka kwayo uye kusimba. Silicone rabha ine huwandu hwakasiyana hwekushandisa, kusanganisira zvisimbiso uye gaskets, magetsi ekudzivirira, uye zvigadzirwa zvekurapa.
Neoprene irabha rekugadzira rinogadzirwa kubva ku chloroprene. Yakatanga kuvandudzwa muma1930 uye yave kushandiswa mumhando dzakasiyana dzekushandisa senge wetsuits, gaskets, uye zvisimbiso. Neoprene inozivikanwa nekupokana kwayo neoiri nemakemikari, pamwe neayo yakanaka yekudzivirira zvivakwa.
Zvivakwa: enzanisa zvakakosha zvimiro zvechimwe nechimwe chinhu
Imwe yemisiyano yakakosha pakati pesilicone rabha uye neoprene ndeyekuti silicone rabha ine tembiricha yepamusoro kupfuura neoprene. Neoprene inokwanisa kushingirira tembiricha inosvika 200°F, ukuwo silicone rabha ichikwanisa kumira tembiricha inosvika 500°F. Uye zvakare, silicone rabha inonyanya kupikisa UV mwenje uye ozone pane neoprene.
Neoprene irabha rekugadzira rakagadzirwa muma1930s. Inoshandiswa mumhando dzakasiyana-siyana dzekushandisa, kusanganisira wetsuits, laptop sleeve, uye mbeva pads. Neoprene ine chiyero chepamusoro chemakemikari kuramba uye haina kuderera nyore nyore. Iyo zvakare inopesana nekupisa uye kutonhora, zvichiita kuti ive chinhu chakanakira kune akawanda ekunze application.
Silicone rabha imwe yerabha yekugadzira iyo yakagadzirwa mukutanga kwezana ramakore rechi20. Silicone rubber ine huwandu hwakawanda hwekushandisa nekuda kweiyo yakasarudzika zvivakwa. Silicone rabha inopesana nekupisa kwakanyanya, UV mwenje, uye makemikari. Iyo inewo yakaderera coefficient ye friction, iyo inoita kuti ive yakakodzera kushandiswa muzvisimbiso uye gaskets.
Ndezvipi zvinobatsira zvesilicone rubber?
Silicone rabha ine zvinhu zvakawanda zvinoita kuti ive sarudzo yakanaka kune akasiyana siyana ekushandisa, anosanganisira yakakwira tembiricha kuramba, yakaderera tembiricha kuramba, magetsi ekuisa, makemikari kuramba, uye compression set kuramba.
Imwe yemabhenefiti akakosha esilicone rubber kuramba kwayo kune tembiricha yakanyanyisa. Inogona kushandiswa munzvimbo dzinobva -55 ° C kusvika +300 ° C (-67 ° F kusvika 572 ° F), zvichiita kuti ive sarudzo yakanaka kune zvakasiyana-siyana zvekushandisa.
Silicone rabha zvakare ine yakanakisa kuramba kune UV mwenje, ozone, uye okisijeni, zvichiita kuti ive yakakodzera kushandiswa kwekunze. Iyo zvakare inopokana nemakemikari, maoiri, uye magirisi, zvichiita kuti ive sarudzo yakanaka kune maapplication apo zvinhu izvi zviripo.
Silicone rabha zvakare chinhu chakanyanya elastic, zvichireva kuti inogona kudzokera kuchimiro chayo chepakutanga kunyangwe yatambanudzwa kana kudzvanywa. Izvi zvinoita kuti ive yakanaka kune maapplication uko kuchinjika kunodiwa.
Chekupedzisira, silicone rabha chinhu chakanyanya kugadzikana kwezvakatipoteredza. Haina chepfu uye inogona kushandiswazve, zvichiita kuti ive sarudzo yakanaka yezvishandiso uko kutarisisa kwezvakatipoteredza kwakakosha.
Ndezvipi zvinobatsira zve neoprene?
Neoprene ine huwandu hwakasiyana hwekushandisa, kusanganisira kushandiswa sepadding uye insulation mune akasiyana maindasitiri. Neoprene rubber kuramba kupisa, mafuta, uye abrasion. Iyo zvakare inoshingirira kuderedzwa kubva muchiedza chezuva uye mamiriro ekunze.
Pane zvakawanda zvinobatsira zvekushandisa neoprene, kusanganisira zvinotevera:
-Inopesana nemafuta, makemikari uye kupisa. Izvi zvinoita kuti ive sarudzo yakanaka yekushandisa mune akawanda maindasitiri maapplication.
-Iyo ine yakanaka insulating zvivakwa, zvichiita kuti ibatsire padding uye insulation.
-Iyo inoshanduka uye yakasununguka kupfeka, ichiita sarudzo yakakurumbira yezvipfeko zvakadai sewetsuits.
-Iyo isingadhure kugadzira, ichiita iyo inodhura-inoshanda sarudzo kune akawanda maapplication.
Ko silicone rabha uye neoprene inofananidzwa sei maererano nemutengo?
Panyaya yemutengo, silicone rabha inowanzo kudhura kupfuura neoprene. Nekudaro, pane zvimwe zvinhu zvinogona kukanganisa mutengo, senge rudzi rwesilicone rubber uye huwandu hwaunoda. Semuenzaniso, yekurapa-giredhi silicone rabha inogona kudhura kupfuura general-chinangwa silicone rabha. Panyaya yehuwandu, kutenga muhuwandu kunogona kuderedza mutengo wese payuniti.
Ndeipi iri nani kune chaiyo maapplication - silicone rabha kana neoprene?
Uyu mubvunzo wakaoma kupindura sezvo zvichibva pane chaiyo application kana chinodiwa. Kazhinji, silicone rabha ine kupikisa kuri nani kune tembiricha yakakwira kupfuura neoprene, zvichiita kuti ive sarudzo yekutanga kune maapplication uko Kupisa kunopesana kwakakosha. Nekudaro, neoprene rabha ine kuramba iri nani kumafuta nemafuta pane silicone rabha, saka ingave sarudzo inosarudzika mumashandisirwo ayo aripo. Mukutaura kwekupikisa kwemakemikari, zvinhu zvose zviri zviviri zvakafanana - zvose zvinopikisa kune akawanda acids uye alkalis, asi hazvifaniri kushandiswa nezvinonyungudutsa.
Ko silicone rabha uye neoprene inofananidzwa sei maererano nekukanganisa kwezvakatipoteredza?
Panyaya yekukanganisa kwezvakatipoteredza, silicone rabha uye neoprene zvakafanana. Ose ari maviri akagadzirwa kubva mukugadzira zvinhu, uye ese ari maviri asina-biodegradable. Nekudaro, silicone rabha inowanzoonekwa seyakanyanya eco-hushamwari pane neoprene.
Mumwe musiyano mukuru pakati pezviviri ndewekuti silicone rabha inogadzirwa kubva kusilicon, chinhu chinongoitika, nepo neoprene inogadzirwa kubva kune petroleum zvigadzirwa. Izvi zvinoita kuti silicone rabha ive inogonekazve sosi. Uyezve, silicone rabha inogona kushandiswazve, nepo neoprene haigone.
Silicone rabha zvakare kashoma kuburitsa makemikari anokuvadza munzvimbo. Neoprene ine chlorofluorocarbons (CFCs), inogona kukuvadza ozone layer, uye polychlorinated biphenyls (PCBs), izvo zvinogona kukonzera matambudziko ehutano muvanhu nemhuka. Silicone rabha haina makemikari anokuvadza aya.
Pakazere, silicone rabha ndiyo yakanyanya eco-inoshamwaridzika sarudzo yezvinhu zviviri izvi.
Ndeipi yaunofanira kusarudza - silicone rubber kana neoprene?
Mhinduro kumubvunzo uyu inoenderana nekuti ndezvipi zvivakwa zvaunokoshesa zvakanyanya murubha zvinhu. Silicone rabha inozivikanwa nekusapisa kwayo, nepo neoprene ichizivikanwa nekuramba kwemafuta.
Silicone Rubber:
-Kupisa kupisa: Silicone rubber inogona kumira kutonhora kusvika ku500 ° F. Zvakadai kupisa kupikisa silicone rubber strip.
-Kuramba kwemamiriro ekunze: Silicone rabha inoshingirira kutonhora kwakanyanya uye kupisa kwakanyanya. Iyo zvakare inopikisa UV mwaranzi, ozone, uye mwando.
-Electrical properties: Silicone rabha ine yakanaka magetsi ekudzivirira zvinhu. Zvakaita se magetsi conductive silicone furo sheet.
-Chemical resistance: Silicone rubber inopesana nemakemikari akawanda nemafuta.
Neoprene Rubber:
-Oiri kuramba: Neoprene rabha ine yakanakisa mafuta kuramba.
-Kudzosa moto: Neoprene rabha inongogara inodzoreredza moto.
-Kuramba kwemamiriro ekunze: Neoprene rabha inoramba kudzikira kubva kuchiedza chezuva uye ozone.
