Rabha resilicone rinobuda kupi?

 

Kuti tinzwisise nzira dzakasiyana-siyana dzinogona kushandiswa silicone rabha, zvakakosha kuziva mavambo ayo. Mublog rino, tinotarisa kuti silicone inobva kupi kuti tinzwisise zvakawanda nezvehunhu hwayo.

 

Kunzwisisa mhando dzakasiyana dzerabha

Kuti unzwisise kuti silicone chii, unofanira kutanga waziva mhando dzakasiyana dzerabha dziripo. Rabha yechisikigo inowanzozivikanwa se latex uye inobva pamuti werabha. Miti iyi yakatanga kuwanikwa muSouth America uye kushandiswa kwerabha mairi kwakatangira mutsika dzeOlmec (Olmec zvinoreva kuti "Vanhu veRabha"!).

Saka chero chinhu chisina kugadzirwa kubva murabha iyi yechisikigo chakagadzirwa nevanhu uye chinozivikanwa sechigadzirwa.

Chinhu chitsva chinogadzirwa nekusanganisa zvinhu zvakasiyana-siyana pamwe chete chinonzi synthetic polymer. Kana polymer iine hunhu hwe elastic, inozivikanwa se elastomer.

 

Chii chinonzi silicone chinogadzirwa?

Silicone inozivikanwa se elastomer yakagadzirwa nekuti ipolymer inoratidza viscoelasticity - kureva kuti inoratidza kusimba uye kusimba. Vanhu vanowanzoti izvi zvinhu zvinochinjika irabha.

Silicone pachayo inoumbwa nekabhoni, hydrogen, okisijeni nesilicon. Cherechedza kuti chinhu chiri musilicone chinonyorwa zvakasiyana. Chinhu chacho chinonzi silicon chinobva mu silica inobva mujecha. Maitiro ekugadzira silicon akaoma uye ane matanho akawanda. Maitiro aya akaoma anobatsira kuti silicone rabha ive nemutengo wepamusoro kana tichienzanisa nerabha yechisikigo.

Maitiro ekugadzira silicone anosanganisira kubvisa silicon kubva mu silica uye kuipfuudza nemumahydrocarbon. Inozosanganiswa nemamwe makemikari kugadzira silicone.

 

Rubha resilicone rinogadzirwa sei?

Rabha reSilicone musanganiswa wemusana weSi-O usingashandiswi, une mapoka anoshanda eorganic. Chisungo chesilicon-oxygen chinoita kuti silicone irambe yakasimba uye ikwanise kuchinjika pakupisa kwakasiyana-siyana.

Iyo silicone polymer inosanganiswa nezvinosimbisa fillers uye zvinobatsira pakugadzira gum yakasimba, iyo inogona kubatanidzwa pakupisa kwakanyanya uchishandisa peroxides kana polyaddition curing. Kana yabatanidzwa, silicone inova chinhu chakasimba, chinonyunguduka.

Pano paSilicone Engineering, zvinhu zvedu zvese zvesilicone zvinogadziriswa nekupisa uko kunoisa zvigadzirwa zvedu zvesilicone muchikamu cheHTV silicone kana High Temperature Vulcanised. Magiredhi edu ese esilicone anogadzirwa, anosanganiswa uye anogadzirwa panzvimbo yedu ine 55,000-sq. ft. muBlackburn, Lancashire. Izvi zvinoreva kuti tine ruzivo rwakakwana uye tinokwanisa kutevedzera maitiro ekugadzira uye tinogona kuve nechokwadi chekuti tinotarisira mhando yepamusoro. Parizvino tiri kugadzira matani anopfuura 2000 esilicone rabha gore rega rega izvo zvinoita kuti tikwanise kukwikwidzana zvakanyanya mumusika wesilicone.

 

Ndezvipi zvakanakira kushandisa silicone rabha?

Maitiro ekugadzira uye kuumbwa kwezvinhu zvinogadzirwa nerabha resilicone zvinoita kuti rikwanise kuchinjika zvakanyanya, izvo zvinoita kuti rive rakakurumbira mukushandiswa kwakawanda. Rinokwanisa kutsungirira kuchinja-chinja kwakanyanya kwekupisa kubva pa -60°C kusvika pa 300°C.

Inodzivirirawo nharaunda zvakanyanya kubva kuOzone, UV uye mamiriro ekunze anowanzoita kuti ive yakanaka pakuvhara kunze uye kudzivirira zvinhu zvemagetsi zvakaita semwenje nemidziyo. Silicone sponge chinhu chakareruka uye chinoshandisika zvakasiyana-siyana chinoita kuti ive yakanaka pakuderedza kudedera, kudzikamisa majoini uye kuderedza ruzha mukati mezvishandiso zvekutakura vanhu vakawanda - zvichiita kuti ive yakakurumbira kushandiswa munzvimbo dzakadai sezvitima nendege uko kunyaradzwa kwevatengi kunobatsirwa nekushandisa silicone rabha.

Iyi ingori pfupiso yekwakabva silicone rabha. Zvisinei, kuJWT Rubber tinonzwisisa kukosha kwazvinoita kuti unzwisise zvese nezvechigadzirwa chauri kutenga. Kana uchida kuziva zvakawanda kuti unzwisise kuti silicone rabha ingashanda sei muindasitiri yako, taura nesu nhasi.
