Sarudza Mutauro 
Under normal conditions, transparent silicone rabha zvigadzirwa kuratidza zvakanakisa weather resistance uye anti-aging performance . Kunyangwe mushure memakore akati wandei ekuchengetedza, ivo kazhinji havaratidzi kutsvuka kuri pachena.
Nekudaro, mukugadzirwa chaiko, hazvishamisi kune vamwe transparent silicone zvigadzirwa kuoneka yero yakatsvuka kana kuti yero zvishoma pakarepo mushure mekudhonzwa . Iyi nyaya inonyanya kukosha kune zvigadzirwa zvine zvakanyanya kutaridzika zvinodiwa, senge O-Rings uye Shock-Absorbing Air Bladders , uko kunyange kuderera kuduku kunooneka zvikuru.
Saka sei uchidaro transparent silicone rabha zvigadzirwa yero panguva yekugadzira? Zvikonzero zvikuru zvinogona kuongororwa kubva pazvinhu zvitatu zvinotevera.
1. Vulcanizing Agent Factors
Kusarudzwa kwe silicone vulcanizing agent ndechimwe chezvinhu zvakakosha zvakanyanya zvinokanganisa kugadzikana kwemavara yezvakajeka silicone zvigadzirwa.
1.1 Misiyano muVulcanizing Agent Types
Silicone vulcanizing agents inogona kukamurwa kuita:
Yakajairwa vulcanizing agents (isina-anti-yellowing type)
Anti-yellowing vulcanizing agents
1.2 Chiyero cheMashandisirwo eVakasiyana Vulcanizing Agents
Standard (Non-Anti-Yellowing) Vulcanizing Agents
Izvi zvinonyanya kushandiswa:
Zvigadzirwa zveSilicone zvakasviba
Zvigadzirwa zvine yakaderera chitarisiko zvinodiwa
Zvisiri-zvakafumurwa kana zvemukati silicone zvikamu
Mienzaniso yakajairika inosanganisira zvimwe indasitiri buffer zvikamu uye zvikamu zvemukati zvemaitiro.
Anti-Yellowing Vulcanizing Agents
Izvi zvakagadzirirwa chaizvo:
Zvikumbiro zvakafumurwa
Chiedza-ruvara kana high-transparency silicone zvigadzirwa , kunyanya:
Transparent Silicone O-Rings
Medical-giredhi kana chikafu-giredhi silicone zvikamu
High-transparency Shock-Absorbing Air Bladders
Kana a standard isiri-anti-yellowing vulcanizing agent inoshandiswa zvisiri izvo kune izvi zvigadzirwa, yellowing ichaitika nyore mushure mevulcanization , kunyangwe iyo base silicone zvinhu pachayo ine yakanakisa kujeka.
2. Processing Conditions
Kunyange kana zvakakodzera anti-yellowing vulcanizing agent inosarudzwa, mamiriro asina kunaka ekugadzirisa inogona kuramba ichikonzera discoloration mune transparent silicone zvigadzirwa.
Zvikonzero zvakajairika zvine chekuita nemaitiro zvinosanganisira:
Kunyanya Kupisa Mold
Kupisa kwakanyanya kwe mold kunomhanyisa maitiro ekupisa mukati mesilicone uye kusanganisa system, zvichitungamira kune inooneka yero tint.
Yakawandisa Vulcanization Nguva
Kugara kwenguva refu kune tembiricha yepamusoro kunogona kukonzera localized thermal kuchembera , iyo inonyanya kuoneka mune transparent silicone zvinhu.
Zvisina Kufanira Kudzora Kurapa
Zvakanyanyisa post-curing tembiricha kana nguva zvinowedzera kuwedzera njodzi yekutsvuka.
Pakugadzira pachena O-Rings kana Shock-Absorbing Air Bladders , zvigadzirwa izvi zvinowanzoratidza madziro matete uye kujeka kwakakwirira , zvichikonzera hwindo rakatetepa kwazvo rekugadzirisa. Chero degree re over-curing inogona kuratidza zvakananga seyakajairika ruvara.
3. Raw Material Quality Issues
Mune zvimwe zviitiko, yellowing ichiri kuitika kunyange kana:
Anti-yellowing vulcanizing agents dzinoshandiswa
Processing parameters dzinodzorwa zvakasimba
Mumamiriro ezvinhu akadaro, chinokonzera kazhinji chiri mu mukati memhando yesilicone mbishi zvinhu pacharo.
Zvikonzero zvinogona kusanganisira:
Kusakwana kuchena kwesilicone base polymer
Zvisaririra zvakaderera-mamorekuru-huremu tsvina
Zvisina kukwana kana zvisina kugadzirwa zvakanaka anti-yellowing system
Kana iyo silicone mbishi zvinhu ine inherently weak anti-yellowing performance , kugadzirisa iyo vulcanizing agent kana mamiriro ekugadzirisa anogona chete kuwana zvishoma kuvandudzwa.
Iyo inonyanya kushanda mhinduro munyaya iyi ndeye kutsiva iyo raw material supply system , iyo inonyanya kukosha yepamusoro-yekupedzisira yakajeka O-Rings uye Shock-Absorbing Air Bladder applications.
Summary
Nyangwe transparent silicone rabha zvigadzirwa zvinopa zvakanakisa weather resistance uye anti-aging properties , kutsvuka kunoitika pakarepo mushure mekugadzirwa rinowanzokonzerwa nechimwe kana zvimwe zvezvinotevera:
Kusarudzika kwakashata kwemumiririri (isina-anti-yellowing mhando yakashandiswa)
Kutadza kutonga kwekugadzirisa parameters (kunyanya tembiricha, nguva, kana kusapora mushure mekurapa)
Kusakwana anti-yellowing kuita kwesilicone mbishi zvinhu
Kunyatso kudzivirira yellowing-kunyanya mukutaridzika-yakakosha maapplication akadai O-Rings uye Shock-Absorbing Air Bladders —vagadziri vanofanira:
Sarudza anti-yellowing vulcanizing agents zvakakodzera
Kunyatsodzora mold tembiricha uye vulcanization nguva
Isa pakutanga yakakwirira-kuchena silicone zvinhu zvine yakagadzikana anti-yellowing performance
Under normal conditions, transparent silicone rabha zvigadzirwa kuratidza zvakanakisa weather resistance uye anti-aging performance.
