Qhov twg Dose silicone roj hmab los ntawm?

 

Txhawm rau nkag siab ntau txoj hauv kev siv cov roj hmab silicone, nws yog ib qho tseem ceeb kom paub txog nws keeb kwm. Hauv blog no, peb saib seb qhov twg silicone los ntawm kev nkag siab ntau ntxiv txog nws cov yam ntxwv.

 

Nkag siab txog ntau hom roj hmab

Txhawm rau nkag siab tias silicone yog dab tsi koj thawj zaug yuav tsum paub txog cov roj hmab sib txawv. Hauv nws daim ntawv purest, cov roj hmab ntuj feem ntau pom tau tias yog latex thiab tiag tiag los ntawm tsob ntoo roj hmab. Cov ntoo no tau pom thawj zaug hauv South America thiab siv cov roj hmab los ntawm lawv hnub rov qab mus rau Olmec kab lis kev cai (Olmec txhais tau tias "Cov Neeg Roj Hmab"!).

Txhua yam uas tsis yog tsim los ntawm cov roj hmab ntuj no yog tib neeg tsim thiab hu ua hluavtaws.

Ib yam khoom tshiab ua los ntawm kev sib xyaw ntau yam khoom ua ke yog hu ua hluavtaws polymer. Yog hais tias lub polymer qhia cov khoom elastic, nws raug txheeb xyuas tias yog elastomer.

 

Dab tsi yog silicone ua los ntawm?

Silicone tau txheeb xyuas tias yog hluavtaws elastomer raws li nws yog ib qho polymer uas qhia txog viscoelasticity - uas yog hais tias nws qhia ob qho tib si viscosity thiab elasticity. Colloquially neeg hu cov elastic yam ntxwv roj hmab.

Silicone nws tus kheej yog tsim los ntawm carbon, hydrogen, oxygen thiab silicon. Nco ntsoov tias cov khoom muaj nyob rau hauv silicone yog spelled txawv. Cov khoom siv silicon yog los ntawm silica uas yog muab los ntawm cov xuab zeb. Cov txheej txheem los ua silicon yog complex thiab muaj ntau theem. Cov txheej txheem nyuaj no pab txhawb rau silicone roj hmab tus nqi hwm piv rau cov roj hmab ntuj.

Cov txheej txheem ua silicon suav nrog kev rho tawm silicon los ntawm silica thiab dhau los ntawm hydrocarbons. Tom qab ntawd nws tau tov nrog lwm cov tshuaj los tsim silicone.

 

Silicone roj hmab ua li cas?

Silicone roj hmab yog ib qho kev sib xyaw ua ke ntawm cov pob txha inorganic Si-O, nrog cov organic ua haujlwm txuas nrog. Silicon-oxygen daim ntawv cog lus muab silicone nws qhov kub thiab txias tsis kam thiab yoog raws ntau qhov kub thiab txias.

Cov silicone polymer yog sib xyaw nrog cov khoom siv ntxiv thiab cov txheej txheem ua haujlwm los tsim cov pos hniav txhav, uas tuaj yeem txuas rau ntawm qhov kub siab siv peroxides lossis polyaddition curing. Thaum crosslinked cov silicone ua ib qho khoom, elastomeric khoom.

Ntawm no ntawm Silicone Engineering, tag nrho peb cov ntaub ntawv silicone tau kho los ntawm kev siv cua sov uas faib peb cov khoom siv silicone li HTV silicone lossis kub kub Vulcanised. Tag nrho peb cov qib silicone yog kitted, sib xyaw thiab tsim ntawm peb 55,000-sq. ft. qhov chaw hauv Blackburn, Lancashire. Qhov no txhais tau tias peb muaj tag nrho traceability thiab lav ris ntawm cov txheej txheem ntau lawm thiab tuaj yeem ua kom cov qauv zoo tshaj plaws ntawm kev tswj xyuas thoob plaws. Peb tam sim no txheej txheem ntau tshaj 2000 tonnes ntawm silicone roj hmab txhua xyoo uas tso cai rau peb muaj kev sib tw heev nyob rau hauv lub lag luam silicone chaw.

 

Dab tsi yog cov txiaj ntsig siv cov roj hmab silicone?

Cov txheej txheem ntau lawm thiab cov khoom muaj pes tsawg leeg ntawm silicone roj hmab muab nws ib tug zoo npaum li cas ntawm yooj, uas yog dab tsi ua rau nws thiaj li nrov rau ntau siv. Nws muaj peev xwm tiv taus qhov kub thiab txias ntawm qhov kub ntawm -60 ° C mus txog 300 ° C.

Nws kuj tseem muaj kev tiv thaiv ib puag ncig zoo los ntawm Ozone, UV thiab huab cua kev ntxhov siab ua rau nws zoo tagnrho rau kev sib khi sab nraum zoov thiab tiv thaiv cov khoom siv hluav taws xob xws li teeb pom kev zoo thiab cov ntaub thaiv npog. Silicone sponge yog cov khoom siv sib sib zog nqus thiab ntau yam ua rau nws zoo tagnrho rau kev txo qis kev vibrations, stabilizing cov pob qij txha thiab txo suab nrov nyob rau hauv cov ntaub ntawv loj thauj mus los - ua rau nws nrov rau siv nyob rau hauv ib puag ncig xws li tsheb ciav hlau thiab dav hlau uas cov neeg siv kev nplij siab yog pab los ntawm kev siv cov roj hmab silicone.

Qhov no tsuas yog ib qho luv luv ntawm lub hauv paus chiv keeb ntawm silicone roj hmab. Txawm li cas los xij, ntawm JWT Rubber peb nkag siab tias nws tseem ceeb npaum li cas yog tias koj nkag siab txhua yam ntawm cov khoom koj tab tom yuav. Yog tias koj xav paub ntau ntxiv kom nkag siab tias silicone roj hmab tuaj yeem ua haujlwm li cas hauv koj txoj kev lag luam ces tiv tauj peb hnub no.
