kev xav tau ntawm silicone rau kev ua khob

kev xav tau ntawm silicone rau kev ua khob
Khoom noj khoom haus kev ruaj ntseg
Cov qauv zaub mov qib:Cov silicone siv hauv silicone khob yuav tsum ua raws li cov qauv zaub mov. Qhov no txhais tau hais tias thaum lub sij hawm tsim khoom, cov khoom siv raw yuav tsum yog cov purity siab thiab yuav tsum tsis txhob muaj cov khoom tsis zoo, xws li cov hlau hnyav (lead, mercury, cadmium, thiab lwm yam) thiab cov tshuaj lom (xws li polycyclic aromatic hydrocarbons, thiab lwm yam). . Piv txwv li, nyob rau hauv European Union, cov zaub mov qib silicone yuav tsum ua raws li cov cai ntawm (EU) Tsis muaj 10/2011 cov cai, thiab nws cov hlau hnyav tsiv teb tsaws muaj kev txwv nruj, thiab kev txwv kev tsiv teb tsaws ntawm cov hlau lead yog 0.05. mg/kg kom muaj kev nyab xeeb ntawm cov neeg siv thaum haus.

Tsis muaj ntxhiab tsw:Silicone yuav tsum tsis muaj ntxhiab tsw, vim tias ntxhiab tsw tuaj yeem cuam tshuam qhov saj ntawm dej thiab tej zaum yuav yog ib qho teeb meem ntawm volatilization ntawm cov tshuaj phem. Tom qab qhib lub pob, lub khob zoo silicone yuav tsum tsuas yog muaj ntxhiab tsw ntxhiab ntawm silicone nws tus kheej, uas yuav ploj sai sai tom qab ntxuav.

Chemical stability:Silicone yuav tsum muaj kev ruaj ntseg zoo. Thaum nws los rau hauv kev sib cuag nrog ntau yam dej haus, xws li dej, kua txiv hmab txiv ntoo, kas fes, tshuaj yej, thiab lwm yam, nws tsis tuaj yeem raug tshuaj lom neeg thiab yuav tsis tso cov tshuaj uas tsim kev puas tsuaj rau tib neeg lub cev. Nws yuav tsum muaj peev xwm tiv taus qee yam ntawm pH qhov tseem ceeb, piv txwv li, haus dej nrog tus nqi pH ntawm 2 thiab 10 yuav tsis ua rau lub khob silicone puas.

Cov kev xav tau ntawm lub cev
Flexibility thiab elasticity:Silicone yuav tsum muaj qhov yooj yim thiab elasticity, uas ua rau lub khob tsis yooj yim tawg thaum nyem los yog sib tsoo. Piv txwv li, thaum lub khob poob rau hauv av, qhov elasticity ntawm silicone tuaj yeem pab nws nqus qhov cuam tshuam thiab txo qhov muaj peev xwm ntawm kev puas tsuaj. Feem ntau hais lus, Shore hardness ntawm silicone yog nyob nruab nrab ntawm 30 thiab 70A, uas ua kom lub khob muaj ib qho kev ruaj khov thiab txaus saj.
Lub zog thiab durability:Silicone yuav tsum muaj lub zog txaus los tiv thaiv lub siab ntawm kev siv txhua hnub. Thaum rov ua dua, nchuav thiab nqa, lub khob silicone yuav tsum tsis txhob torn lossis puas. Rau qee lub khob nrog tes, hooks thiab lwm yam qauv, silicone yuav tsum muaj peev xwm tiv taus qhov sib thooj ntawm cov khoom no. Piv txwv li, silicone nyob rau hauv lub kov ntawm lub khob yuav tsum muaj peev xwm tiv taus tsawg kawg yog 5kg ntawm nro yam tsis tau tawg tom qab kuaj.
Transparency thiab tsos zoo(yog tias nws yog pob tshab silicone): Yog tias lub khob yog ua los ntawm pob tshab silicone, lub pob tshab ntawm silicone yuav tsum siab, thiab yuav tsum tsis muaj qhov pom tseeb turbidity, npuas, thiab lwm yam uas cuam tshuam rau cov tsos. Silicone nrog lub siab pob tshab tso cai rau cov neeg siv kom pom tseeb cov kua hauv lub khob, thiab tseem txhim kho qhov zoo ntawm lub khob. Feem ntau, lub teeb transmittance ntawm pob tshab silicone yuav tsum siab tshaj 85%.
Thermal kev ua haujlwm xav tau
Thaum tshav kub kub kuj:Silicone khob tuaj yeem siv los tuav cov dej kub, yog li silicone yuav tsum muaj cov cua kub zoo. Nws yuav tsum muaj peev xwm tiv taus qhov kub thiab txias, piv txwv li, yam tsawg kawg 100 degree yam tsis muaj deformation, softening, thiab lwm yam. Qee lub khob silicone kuj tseem siv tau rau hauv cov txheej txheem tshuaj tua kab mob kub, yog li silicone uas tuaj yeem tiv taus 120 degree lossis txawm tias kub dua yog ntau dua. muaj txiaj ntsig.
Thaum tshav kub kub rwb thaiv tsev(yog tias yuav tsum tau): Yog tias lub khob tsim yuav tsum muaj kev tiv thaiv hluav taws kub, qhov kev ua haujlwm kub ntawm silicone nws tus kheej kuj yog ib qho kev txiav txim siab. Txawm hais tias silicone tsis yog cov khoom siv hluav taws xob zoo tshaj plaws, nws tuaj yeem txhim kho los ntawm kev tsim tsim nyog, xws li ob txheej txheej silicone nrog cov cua txheej tsim nyob rau hauv nruab nrab. Los yog ua ke nrog lwm cov ntaub ntawv rwb thaiv tsev kub, sab nraum lub khob yuav tsis kub heev thaum tuav dej kub.
Cov kev xav tau ntawm kev ua haujlwm
Moldability:Silicone yuav tsum yooj yim rau txheej txheem thiab tuaj yeem ua rau ntau yam duab ntawm lub khob los ntawm kev txhaj tshuaj molding, extrusion thiab lwm yam txheej txheem. Piv txwv li, thaum lub sij hawm txhaj tshuaj molding txheej txheem, lub fluidity ntawm silicone yuav tsum zoo, thiab nws muaj peev xwm sib npaug ntawm cov pwm kab noj hniav kom paub meej tias qhov ntev ntawm txhua feem ntawm lub khob yog qhov tseeb thiab cov phab ntsa thickness yog uniform.
Compatibility nrog rau lwm yam Cheebtsam:Yog hais tias lub khob muaj lwm yam khoom, xws li cov yas npog, stainless hlau lim, thiab lwm yam, silicone yuav tsum muaj peev xwm ua ke zoo nrog cov khoom no. Piv txwv li, thaum silicone thiab yas npog txuas nrog cov kua nplaum lossis cov qauv siv tshuab, silicone tsis tuaj yeem hnov ​​​​mob chemically nrog cov kua nplaum, thiab qhov ruaj khov ntawm kev sib txuas yuav tsum tau ua kom ntseeg tau.
