Mutengesi akavimbika wezvinhu zvinonyorovesa

tsananguro pfupi:

Zvinonyorovesa zvinhu zvinoderedza kushushikana kwemvura pamusoro pemvura, zvichiita kuti ipararire zviri nyore. Zvinowanzoshandiswa mumabasa akasiyana-siyana, anosanganisira chikafu, zvizoro, kugadzira mapepa, kugadzirisa mvura, sipo, kugadzira shuga, kuvirisa, kuputira, kudhinda nekudhaya machira, kubhoora nekunatsa, mafuta ehydraulic nemafuta ekuzora emhando yepamusoro, zvinosunungura, nezvimwe zvinhu zvakawanda.

Zvinonyorovesa, rudzi rwepolyorganosiloxane ine chimiro checheni chemazinga akasiyana epolymerization, inoshanda sechinhu chinonyorovesa chinoshamisa. Chinogadzirwa kuburikidza nehydrolysis ye dimethyldichlorosilane nemvura kuti chiwane ring yekutanga ye condensation. Ring yacho inobva yatsemuka, yogadziriswa kuti igadzire ring yeChemicalbook yakaderera, uye yobatanidzwa ne head agent uye catalyst ye polymerization. Maitiro aya anoguma nemhando dzakasiyana dzemisanganiswa yeWetting agents ine mazinga akasiyana e polymerization. Zvikamu zvinofashaira zvishoma zvinobviswa kuburikidza ne vacuum distillation kuti zviwane Wetting agents yekupedzisira.

Kunze kwekuva chinhu chinonyorovesa, oiri yesilicone ine zvimwe zvakawanda uye mashandisirwo ayo. Inowanzoshandiswa semushonga wekubvisa mafoam mumaindasitiri akadai sekugadzira chikafu, kugadzira zvizoro, uye kugadzira mapepa. Nekuderedza kuumbwa kwefuro zvinobudirira, oiri yesilicone inowedzera maitiro ekugadzira. Pamusoro pezvo, inoshandiswa sechinhu chakakosha mukugadzirwa kwesilicone resin nerabha yesilicone. Zvinhu izvi zvinoshandiswa zvakanyanya sezvinamathero, zvinowedzera mapurasitiki anodzivirira moto, zvinhu zvinodzivirira kupisa, nezvimwewo.

Kushanda nesimba kwemafuta esilicone kunoonekwawo nekushanda kwawo semushonga wekupedzisa muindasitiri yematehwe. Anobatsira mukuvandudza chitarisiko, magadzirirwo, uye kugara kwenguva refu kwezvigadzirwa zvematehwe. Uyezve, mune mamwe mabasa akasiyana-siyana, akadai sekugadzira sipo yemhando yepamusoro, haingoshandi semushonga wekunyorovesa chete asiwo inoshanda sechinhu chakakosha pakugadzira uye kugadzikana kweganda.

Zvakanakira

(1) Kushanda kwe viscosity ndiko kwakanakisa mumafuta emvura, uye kuchinja kwe viscosity mukupisa kwakafara kudiki. Poindi yayo ye condensate inowanzova pasi pe -50 ° C, uye imwe inosvika -70 ° C. Inochengetwa kwenguva yakareba pakupisa kwakaderera. Chitarisiko uye viscosity yezvigadzirwa zvayo zvemafuta hazvina kuchinja. Ndiwo mafuta ekutanga anofunga nezvekupisa kwakakwira, kupisa kwakaderera, uye kupisa kwakafara.

(2) Kugadzikana kwakanaka kwekupisa, senge kupisa kunoora> 300 ° C, kurasikirwa kudiki kwekubuda kwemvura (150 ° C, mazuva makumi matatu, kurasikirwa kwekubuda kwemvura kunongova 2%), bvunzo yekubuda kwemvura (200 ° C, 72H), kuchinja kwehunhu hwe viscosity uye acid.

(3) Kudzivirira kwemagetsi kwakanaka, kuramba vhoriyamu, nezvimwewo. Mukupisa kwakajairika ～ 130 ℃, hazvichinji (asi mafuta haagoni kuva mvura).

(4) Imafuta asina chepfu uye ane furo shoma uye akasimba anodzivirira mapombi, anogona kushandiswa sechidziviriro.

(5) Kugadzikana kwakanaka kwazvo kwekuchekerera, izvo zvinogona kutora kudedera uye kudzivirira kufambiswa kwededera.
