Ese umupira wa silicone ukoreshwa mu gupima uturuka he?

 

Kugira ngo dusobanukirwe uburyo bwinshi bwo gukoresha silicone rubber, ni ngombwa kumenya inkomoko yayo. Muri iyi blog, turareba aho silicone ikomoka kugira ngo dusobanukirwe byinshi ku miterere yayo.

 

Gusobanukirwa ubwoko butandukanye bwa kabutura

Kugira ngo usobanukirwe icyo silicone ari cyo, ugomba kubanza kumenya ubwoko butandukanye bwa rabu iboneka. Mu buryo bwayo bwiza, rabu karemano izwi cyane nka latex kandi mu by'ukuri ikomoka ku giti cya rabu. Ibi biti byavumbuwe bwa mbere muri Amerika y'Epfo kandi ikoreshwa rya rabu muri byo ryatangiye kuva mu muco wa Olmec (Olmec bivuze "Abantu ba Rubu"!).

Bityo rero, ikintu cyose kitakozwe muri uyu muti usanzwe kiba cyarakozwe n'umuntu kandi kizwi nk'icya sintetike.

Ikintu gishya gikozwe mu kuvanga ibikoresho bitandukanye cyitwa polymer y’ubukorikori. Iyo polymer igaragaza imiterere ya elastic, imenyekana nka elastomer.

 

Silikoni ikorwa mu ki?

Silicone izwiho kuba elastomer y’ubukorikori kuko ari polymer igaragaza ubukana bw’ubukorikori - ni ukuvuga ko igaragaza ubukana n’ubukorikori. Mu mvugo abantu bakunze kwita ibi biranga ubukorikori bw’ubukorikori.

Silicone ubwayo igizwe na karuboni, hidrojeni, ogisijeni na silicon. Menya ko ikintu kiri muri silicone cyanditswe mu buryo butandukanye. Silicone ikomoka kuri silika ikomoka ku mucanga. Uburyo bwo gukora silicon buragoye kandi bugira ibyiciro byinshi. Ubu buryo buragoye butuma silicone igura igiciro cyiza ugereranyije na silicon karemano.

Uburyo bwo gukora silicone burimo gukura silikoni muri silikoni no kuyinyuza muri hydrocarbon. Hanyuma ikavangwa n'indi miti kugira ngo ikore silikoni.

 

Rubber ya silicone ikorwa ite?

Rubber ya silikoni ni uruvange rw'umugongo wa Si-O udafite umwimerere, hamwe n'amatsinda y'imikorere ya organic. Ihuriro rya silikoni na ogisijeni rituma silikoni idashobora gushyuha cyane no koroha mu bushyuhe bwinshi.

Polymeri ya silikoni ivangwa n'ibikoresho byo kongera imbaraga n'ibikoresho bifasha mu gutunganya shinya ikomeye, ishobora guhuzwa ku bushyuhe bwinshi hakoreshejwe peroxide cyangwa polyaddition curing. Iyo silicone imaze guhuzwa iba ibikoresho bikomeye kandi birekuye.

Hano muri Silicone Engineering, ibikoresho byacu byose bya silicone bivurwa hakoreshejwe ubushyuhe bushyira ibicuruzwa byacu bya silicone mu byiciro bya HTV silicone cyangwa High Temperature Vulcanized. Ibipimo byacu byose bya silicone bivangwa, bikanakorerwa mu ruganda rwacu rwa metero kare 55.000 ruri i Blackburn, muri Lancashire. Ibi bivuze ko dufite ubushobozi bwo gukurikirana no kugenzura ibikorwa by'umusaruro kandi dushobora kwemeza ko ducunga neza mu buryo bwiza. Ubu dutunganya toni zirenga 2000 za silicone rubber buri mwaka, ibi bigatuma tubasha guhangana cyane ku isoko rya silicone.

 

Ni izihe nyungu zo gukoresha silicone rubber?

Uburyo bwo kuyikora n'imiterere yayo biyitera ubushobozi bwo koroshya ibintu, ari nabyo bituma ikundwa cyane kubera uburyo bwinshi bwo kuyikoresha. Ishobora kwihanganira ihindagurika ry'ubushyuhe kuva kuri -60°C kugeza kuri 300°C.

Ifite kandi ubushobozi bwo kurwanya ibidukikije buterwa na ozone, UV ndetse n'ihindagurika ry'ikirere muri rusange, bigatuma iba nziza cyane mu gufunga no kurinda ibikoresho by'amashanyarazi nk'amatara n'ibiziriko. Silikoni sponge ni ibikoresho byoroshye kandi bifite uburyo bwinshi, bigatuma iba nziza mu kugabanya imihindagurikire y'ikirere, gutuma ingingo zituza ndetse no kugabanya urusaku mu ngendo nyinshi - bigatuma ikundwa gukoreshwa mu bidukikije nka gari ya moshi n'indege aho abakiriya barushaho kumererwa neza binyuze mu gukoresha silikoni.

Iyi ni incamake y'inkomoko ya silicone rubber. Ariko, muri JWT Rubber turasobanukiwe akamaro ko usobanukirwa byose ku bicuruzwa ugura. Niba wifuza kumenya byinshi kugira ngo usobanukirwe uburyo silicone rubber ishobora gukora mu nganda zawe, twandikire uyu munsi.
