Kune akawanda akasiyana marudzi erabha pamusika nhasi, asi maviri eanonyanya kufarirwa isilicone rubber uye latex. Ivo vese vane yavo yakasarudzika seti yezvivakwa inoita kuti vakwanise kune zvakasiyana zvinangwa. Muchinyorwa chino, tichafananidza nekusiyanisa zvinhu zviviri izvi maererano nechimiro chazvo uye chemakemikari zvimiro, pamwe nemashandisirwo azvo.
Nhanganyaya: chii chinonzi silicone rabha uye latex?
Silicone rabha uye latex ese ari maviri mapolymer, zvichireva kuti anoumbwa nemacheni marefu emamorekuru. Iwo ese ari maviri elastic, zvichireva kuti anogona kutambanudzwa uye ozodzokera kune yawo yekutanga chimiro. Silicone rabha i polymer yakagadzirwa nesilicone, okisijeni, uye maatomu ehydrogen. Latex ipolymer yakasikwa yakagadzirwa nemakomisheni anowanikwa muzvirimwa. Izvo zviri zviviri zvinoshandiswa muzvigadzirwa zvinoda kuchinjika uye zvine mwero wepamusoro wekupokana nekupisa uye kutonhora. Zvisinei, pane zvimwe zvakakosha zvakasiyana pakati pezvinhu zviviri izvi.
Silicone rabha inogadzirwa kubva kusilicone, yakagadzirwa polymer. Iine mwero wepamusoro wekupisa kupisa kupfuura latex, ichiita kuti ive yakanaka kune zvigadzirwa zvinozoratidzwa kune yakanyanya kupisa. Inopesanawo nemafuta nemakemikari, izvo zvinoita kuti zvive zvakanaka kuti zvishandiswe mumidziyo yezvokurapa kana zvisimbiso zvinoda kupikisa mamiriro akaoma. Nekudaro, silicone rabha inodhura kupfuura latex.
Latex inogadzirwa kubva kune yakasikwa rabha, iyo inobva mumuto weimwe miti. Iyo inodhura zvishoma kudarika silicone rubber asi kwete sekudzivirira kutonhora kwakanyanya kana makemikari.
Ndeupi musiyano uripo pakati pesilicone rubber uye latex?
-Ese ari maviri silicone rubber uye latex ari elastic mapolymer ane huwandu hwakasiyana hwekushandisa.
-Silicone rabha inogadzirwa kubva kusilicon, chinhu chakasikwa chinowanikwa mujecha uye quartz. Latex inobva kune zvakasiyana-siyana zvezvisikwa zvakadai semuti wemuti nemukaka. Nekuda kweizvozvo, silicone rabha inodzivirira kupisa uye yakasimba kupfuura latex.
-Silicone rabha irabha yekugadzira uye inopesana nekupisa kwakanyanya, UV mwenje, ozone, uye kuparara kwemakemikari. Latex ipolymer yechisikigo inogona kushatisa nekufamba kwenguva kana yaiswa kuchiedza chezuva uye ozone. Silicone rabha haiputsike nyore nyore selatex kana yakafumurwa kune UV mwenje kana zvimwe zvinhu
-Silicone rubber haibatanidzi nezvimwe zvinhu, nepo latex inogona kukonzera kusawirirana mune vamwe vanhu. Silicone rabha kazhinji haina allergic kupfuura latex.
Zvivakwa zvesilicone rubber: kupisa kupisa, kusamira kwemamiriro ekunze, magetsi ekudzivirira
Silicone rabha elastomer inoumbwa nesilicone — pachayo polymer — uye oxygen. Silicone rubber anoshandiswa zvakanyanya muindasitiri, uye kune akawanda magadzirirwo. Silicone rubbers inosiyana mune yavo yemuviri uye makemikari zvimiro, izvo zvinorairwa nerudzi rwesilicone oiri, cross-linking agent, fillers, uye additives inoshandiswa. Zvakajairika zvimiro zvesilicone rubbers zvinosanganisira:
-Kupisa kupisa: Silicone rubbers inogona kumira kutonhora kubva -55 kusvika 300 ° C (-67 kusvika 572 ° F) vachiri kuchengetedza zvinhu zvavo zvinobatsira. Silicone rubber strips inoshingirira kune tembiricha yakanyanyisa, inopisa uye inotonhora, zvichiita kuti ive yakakodzera kushandiswa munzvimbo dzakasiyana siyana.
-Kuramba kwemamiriro ekunze: Silicone rabha haidzikisi kana yakavhenekerwa nechiedza chezuva kana mamiriro ekunze semamwe ma elastomers. Ichi chivakwa chinoita kuti ive yakanaka kune ekunze maapplication uko zvimwe zvinhu zvinokurumidza kushatisa. Kupokana nemvura Kunyangwe silicone rabha isiri yechokwadi inodzivirira mvura, inogona kumira nehumwe hunyoro. A silicone rubber gasket inogona kushandiswa mumhando dzakasiyana-siyana dzekushandisa dzinoratidzwa kune yakakwira humidity kana kunaya.
-Electrical insulation: Silicone rabha yakanakisa magetsi insulator. Iyo ine yakakwira dielectric simba uye inogona kushingirira yakakwira voltages. Silicone rabha zvakare ine yakaderera yekupisa conductivity, ichiita kuti ive yakakodzera kushandiswa mumagetsi ekushandisa uko kupisa kupisa kuri kunetseka. Silicone rabha zvakare inopesana neozone uye ultraviolet mwaranzi, ichiiita chinhu chakanakira zvekushandisa kunze.
-Inopesana nemvura nemakemikari: Inopikisa zvakare mvura nemakemikari, zvichiita kuti ive yakakodzera kushandiswa mukurapa, chikafu uye chinwiwa, uye kushandiswa kwemaindasitiri. Silicone rabha zvakare isiri-chepfu uye hypoallergenic, zvichiita kuti ive yakachengeteka kushandiswa neganda rinonzwa.
Zvivakwa zve latex: biodegradable, elasticity, yakachengeteka uye yakasimba
Latex chinhu chinoora chinogadzirwa kubva muto wemiti yerabha. Icho chinhu chechisikigo, uye nekudaro chine mamwe mabhenefiti ekuzvarwa pamusoro pezvinhu zvekugadzira sesilicone.
Latex yakanyanya elastic, zvichireva kuti inogona kutambanudzwa uye kudzoserwa kune yayo yekutanga isina kukuvara. Izvi zvinoita kuti ive yakanakira kushandiswa muzvishandiso zvakawanda, senge magurovhosi, makondomu, uye mabharumu. Latex zvakare inopesana neUV mwenje uye oksijeni, zvichiita kuti igare yakasimba kupfuura zvimwe zvinhu.
Latex chinhu chave chichishandiswa mune zvigadzirwa kwemakore mazhinji. Yakagadzirwa kubva kune yakasikwa zvinhu uye saka inoodza biodegradable. Iyo zvakare hypoallergenic, saka yakachengeteka kune vanhu vane latex allergies.
Latex zvakare inogara yakasimba uye ine yakanyanya kupikisa kubvarura.
Izvo zvinokanganisa zvesilicone rubber
Chimwe chezvipingamupinyi zvikuru zvesilicone rubber mutengo wayo. Silicone rabha inodhura kupfuura mamwe marudzi erabha, seyakasikwa rabha, neoprene rubber uye urethane rubber.
Izvo zvinokanganisa zve latex
Nepo latex ine akawanda mabhenefiti, kune zvakare zvimwe zvinogona kukanganisa kufunga. Semuenzaniso, latex inogona kukonzera kusawirirana mune vamwe vanhu. Pamusoro pezvo, latex haigadzirike uye nekudaro haisi sarudzo ine hushamwari.
Kushandiswa kwesilicone rabha: midziyo yekurapa, cookware, sealants
Silicone rubber tubes anoshandiswa mumhando dzakasiyana dzemidziyo yekurapa nekuti inert, zvichireva kuti haidyidzane nemuviri kana kukonzera kurambwa sezvimwe zvimwe zvinhu. Iyo zvakare inoshanduka uye inogona kuchengetedza chimiro chayo nekufamba kwenguva, ichiita kuti ive yakakodzera kushandiswa kwenguva refu mumaimplants uye prosthetics. Pamusoro pezvo, rabha yesilicone haiputsi kana yaiswa mumvura yemuviri kana tembiricha yakakwira, zvichiita kuti ive yakanakira kushandiswa mukubika uye zvisimbiso.
Kushandiswa kwelatex: magirovhosi, makondomu, mabharumu
Kune akawanda mashandisirwo emagurovhosi elatex, makondomu nemabharumu. latex chinhu chinotorwa kubva muto remiti yerabha. Icho chigadzirwa chechisikigo chinogadziriswa uye hypoallergenic. Yakashandiswa kwemazana emakore mune zvakawanda zvakasiyana-siyana zvekushandisa.
Magurovhosi eLatex anowanzoshandiswa munharaunda yekurapa, sezvo achipa chipingamupinyi pakati pemurwere nemutarisiri. Izvo zvinoshandiswawo mubasa rekudya, sezvo zvinodzivirira kubva kune zvirwere zvekudya. Makondomu anogadzirwa nelatex uye anoshandiswa kudzivirira kubata pamuviri uye kupararira kwezvirwere zvepabonde. Mabharumu anogadzirwawo nelatex uye anowanzo shandiswa pakushongedza kana semabiko anofarira.
Latex inoshandiswa mukugadzira pendi yelatex, simende yerabha, uye zvimwe zvigadzirwa zvemumba. Latex inowanzoshandiswa muindasitiri yekuvaka, sezvo inogona kushandiswa kugadzira masimbi ekudzivirira mamiriro ekunze uye zvinonamira.
mhedziso
Kune akawanda akasiyana marudzi erabha pamusika, imwe neimwe iine seti yayo yezvibatsiro uye zvinokanganisa. Panyaya yesilicone rubber vs latex, zviri pachena kuti silicone rabha ine akati wandei mabhenefiti pane latex. Silicone rabha inogara yakasimba, ine yakanyanya kupisa kupisa, uye kashoma kukonzeresa kusawirirana nelatex. Zvisinei, latex kazhinji inodhura kudarika silicone rabha, uye inogona kunge iri sarudzo iri nani kune zvikumbiro apo kushanduka uye kusimba kwakakosha kudarika kusimba.
