Sarudza Mutauro Silicone Rubber chikamu chikuru pakati organic silicon zvigadzirwa . Iyo yakakwira-molecular polymer ine inorganic SI-O-SI Main keteni chimiro uye organic mativi mapoka, achibatanidza ese malorganic uye organic hunhu.
Tichienzaniswa neakajairwa organic rubber, Silicone Rubber vane zvakanaka kupisa kupokana, Kupokana Kwemamiriro ekunze, Magetsi insulation, Chemical Kugadzikana , uye nyyama interness , zvichiita kuti ishandiswe zvakanyanya mukati magetsi, Electronics, Zvemotokari, chikafu, imba , uye zvigadzirwa zvekuzorora Maindasitiri.
1. Yakakwira-tembiricha vulcanized silicone rubber
Silicone Rubber inonyanya kuiswa mukati Yakakwira-tembiricha Vulcanized (HTV) uye Kamuri-tembiricha Vulcanized (rTV) mhando. The the RTV Silicone Rubber inogona kupatsanurana mukati kurongedza-kurapa uye kuwedzera-kurapa masisitimu.
HTV Silicone Rubber inonyanya kushandiswa kuburitsa zvakasiyana Vulcanized Rubber zvikamu , zvakaita se Zvemotokari kusimbisa mhete, gasi, tambo yetambo, Keyboard inodzidzisa zvidimbu , uye Medicone silicone machubhu.
Mukupesana ne, RTV Silicone Rubber inowanzoshandiswa se Mahwira, Potting makomendi , kana MOLD-kugadzira zvinhu , mamwe eiyo basa se Isiri-Vulcanized Rubber zvikamu mukugadzirisa gare gare kana zvivakwa zvekudzivirira.
HTV Silicone Rubber Inosanganisira akati wandei marudzi: MetHyl Silicone Rubber (MQ), methyl vinyl silicone rubber (vmq, iyo inonyanya kushandiswa) , uye Methyl Vinyl Phenyl Silicone Rubber (PVMQ) , inozivikanwa nekuda kwayo yakaderera-tembiricha uye radiation kuramba.
Pakati pavo, VMQ ine chidiki chidiki cheVinyl side ngetani, inosimudzira chiitiko cheVulcanization. Inogona kushandisa akasiyana siyana Peroxide kuronga vamiririri uye zvinobudirira zvinovandudza Kudzvinyirira Kwakaisa Kudzivisa , chivakwa chakaoma Yakakwira-performance Vulcanized Rubber zvikamu zvakaita se O-mhete uye Kuisa Misiti.
Izvi zvinyorwa zvinoratidzira hunhu hwakanakisa hwekugadzirisa, zvakanyanyisa kuturika nzvimbo, uye kushanda nyore, kuzviita chimwe chezvakanyanya kushandiswa Htv sickone rubber mumusika.
1.1 Inokonzeresa yero mune silicone rubber
Mukugadzirwa chaiko kwe HTV Silicone Rubber , a Sekondari Vulcanization maitiro anowanzodikanwa kubvisa zvakasara peroxide byZvigadzirwa uye kuwedzera kuyambuka density , nokudaro kuwedzeredza iyo Simba reMuchina uye Kugadzikana of Vulcanized Rubber zvikamu.
Nekudaro, panguva iyi, vamwe Silicone zvigadzirwa zveRabha inogona kuratidzira yero kana kuderera transparency , zvakanangana zvakananga kushandisa kwavo mune yakakwirira-vaindori maindasitiri akadai chikafu, zvekurapa , uye Solar PhotosVoltaic zvikamu.
Tsvagurudzo inoratidza kuti zvinokonzeresa yero zvinosanganisira:
Tsvaga zvinhu zvesimbi kana nitrate ions (no₃⁻) Mune row gamu kana yekuwedzera, iyo inokonzeresa yero panguva yechipiri yekuita;
Peroxide Decomposition kugadzira acetone , zvichitungamira α-hydroxybutyraldehyde concensionation uye Conjugated Compound Fomu;
The the ph level of fumed silica kukurudzira zvakanyanya yellowing kuwedzera.
Nokudaro, kugadzirisa matanho kazhinji kunotarisa RAW GUM, fumed silica , uye zvinowedzera.
1.2 matanho ekuvandudza yellowing kuramba
Vatsvagiri vakatsvaga akawanda anti-yellowing mhinduro , zvakaita se:
Uchishandisa yakagadziridzwa silicone mafuta izvo zvinoitwa seese maviri a Crosslinking Co-Agent uye Anti-yellowing mumiririri panguva yekuita
Kushandira paste-mhando bis (2,5-peroxide) vulcanizing vamiririri Nekugadzikana kwakasimbiswa kugadzira zvakanyanya pachena Vulcanized Rubber zvikamu ; (https://www.sunlitetek.com/)
Kuunza organic surfacants Munguva rumed silica kurapwa kudzora zviyero zvevhu uye kuvandudza kupararira;
Kuwedzera pyrophosphate-based anti-yellowing yekuwedzera , iyo inosimbisa anti-yellowing performance pasina kukanganisa denderedzwa rabha rabha.
Iyi nzira isingori chete chitarisiko of Silicone zvigadzirwa zveRabha , asi zvakare ivhu Kugadzirisa Kugadzikana of Isiri-Vulcanized Rubber zvikamu panguva yekugadzirira uye sekondari yekuita.
2. Mhedziso
Mumakore achangopfuura, China Organic Silicon Indasitiri yakawedzera nekukurumidza, ne Monomer Kugadzirwa Kugona Kusvika paSturation. Misangano mikuru ndeyekusimuka High-mhando uye yakashanda silicone zvigadzirwa.
Vulcanized Rubber zvikamu vava bazi rakakosha re Yakakwira-kupera Silicone Rubber zvigadzirwa , kuishandiswa zvakanyanya mu Zvemotokari, Kuvaka, Electronics, zvekurapa , uye simba idzva Maindasitiri.
Zvichakadaro, Isiri-Vulcanized Rubber zvikamu zviri kuwedzera kushandiswa mukati Adhishing, Kuisa Mbiri , uye Kuzadza Kuzadza zvikumbiro, kugadzira chinongedzo chinongedzo mu Silicone Rubber Kugadzira Chain.
Sezvo tarisiro yemusika yechitarisiko uye kuita ichiramba ichikwira, kudzivirira yero uye kuchengetedza transparency uye Kugadzikana mukati Silicone zvigadzirwa zveRabha vava nhare dzinokosha dzevanotamba dzinotora zvinhu zvinosimudzira uye zvinoshandiswa kwazvo zveSilicone Rubber.
Silicone Rubber chikamu chikuru pakati organic silicon zvigadzirwa.
