MuMunda WeOrganic Silicon, yakadzika silicon yerubha zvinhu zvinogona kupatsanurwa kuita yakasimba uye yemvura zvinhu, uye zvese zviri zviviri zviri kushandiswa zvakanyanya mumaindasitiri makuru akasiyana, senge potting girazi glue, organic silicone mvura, uye yekuisa chisimbiso chesilicon Rubber zvigadzirwa, zvemagetsi. kuisa chisimbiso, etc. Pane zvakawanda zvakafanana pakati pemashandisirwo eminda yavo uye zvinhu zvenyama, uye maitiro avo ekugadzira akasiyana.Mumunda wezvigadzirwa, mabasa avo nemabasa zvakangofanana.Ndeupi musiyano uripo pakati pezvinhu uye zvigadzirwa?

Musiyano mukuru pakati pemvura silica gel uye yakasimba silica gel ndeye: imwe imvura uye imwe yakasimba;asi mushure mekugadzirisa chigadzirwa chakapedzwa, izvo zviviri hazvisi nyore kusiyanisa.Liquid silica gel imvura uye ine fluidity.Solid silica gel yakasimba uye haina fluidity.

Nzvimbo dzakasiyana dzekushandisa:
(1) Liquid silicone inowanzoshandiswa muzvigadzirwa zvevana, zvigadzirwa zvekicheni yesilicone uye zvigadzirwa zvekurapa, inogona kubata zvakananga chikafu uye muviri wemunhu;

(2) Solid silica gel inowanzoshandiswa kune zvinodiwa zvezuva nezuva, maindasitiri akasiyana siyana uye zvikamu zvemotokari;

(3) Kuchengetedzwa kwemvura silica gel uye yakasimba silica gel: Liquid silica gel chinhu chakajeka, chepamusoro-chekuchengetedza chikafu-giredhi zvinhu.Hapana zvinhu zvekubatsira senge vulcanizing agent inowedzerwa panguva yekuumbwa.Iyo yekuisa chisimbiso inoumbwa nekuisa chisimbiso.

Solid silica gel chinhu chinopenya.Vulcanization inodiwa kuti ikurumidze kupora nguva.

Kuumba:

Liquid Silicone (LSR): Iro zita rakazara ijekiseni rekugadzira mvura silicone rabha, uye vulcanization mudziyo mushini wekuumba jekiseni.Iyo jekiseni yekuumba muchina maitiro ari nyore kwazvo, iko kurongeka kwechigadzirwa kwakakwira, uye kubuda kwacho kwakakwira (iyo A / B glue inosanganiswa kwemasekonzi mashoma pane imwe tembiricha).Izvo zvinhu zvinosanganiswa uye zvinowedzerwa neruvara glue uye catalyst yekupinza otomatiki mugomba rekugadzira pasina manyorero ekushanda.Zvibereko zvechigadzirwa Chigadzirwa chine mvura yakanaka, kutambanudza kwakasimba uye kusimba, uye mold inosanganiswa jekiseni kuumba, saka chigadzirwa chine chiteshi chejekiseni chepurasitiki uye pasina mitsara yekuparadzanisa.

Solid Silicone: Iyo mbishi yezvinhu yakasimba silica gel molding yakasimba.Mushure meiyo silicone rubber chigadzirwa chekugadzira yakasanganiswa nemusanganisi, inoda kuwedzera ruvara glue uye catalyst, uye woicheka muhukuru hwakakodzera uye nemaoko uiise mugomba rekuumba kuti iumbe uye kurapa.Iyo otomatiki yekugadzirisa nzira inoda manyore kushanda kutora mold uye kuburitsa zvinhu.Nekuti iyo zvinhu yakasimba, iyo fluidity uye kutambanudza kusimba kwakadzikira zvishoma pane iyo yemvura.Chigadzirwa chacho hachina chiteshi chejekiseni, uye iyo yakagadziridzwa yakapera chigadzirwa ichava nepamusoro uye yakaderera mitsara yekuparadzanisa.

Ndeupi Musiyano Pakati PeLiquid Silicone Uye Solid Silicone Zvishandiso?
Solid silica gel inogadzirwa mumaindasitiri negirazi remvura (sodium silicate) seyakagadzirwa, hydrolyzed mune asidhi yepakati kuti igadzire gel, yozoitwa silica gel kuburikidza nekuchembera, kugeza, kuomesa, nezvimwewo, zvichienderana nehuwandu hwemvura. translucent kana white solid.Zvigadzirwa zviri pamusika zvine zvisingaite granular, spherical, uye microspherical silica gels, ayo anowanzo shandiswa sezvinokonzeresa vulcanization mumabasa emubhedha anoyerera.

piri.Kana ichishandiswa sechinhu chinotakura, iyo silica gel inowanzonyudzwa mumushonga une catalytically active components, kuitira kuti mhinduro yacho inopinda mumapores e silica gel, uye zvikamu zvinoshanda zvinogoverwa pamusoro pe silica.Gelation kuburikidza nekuomeswa, activation, etc. Iyo pore chimiro chesilica gel ine zvakakosha pesvedzero pazvimiro zveyakagadzirirwa inotsigirwa catalyst, senge pore vhoriyamu uye pore saizi yekugovera silica gel.Kazhinji, silica gel ine avhareji pore dhayamita isingasviki 15 kusvika 20 inonzi yakanaka pore silica gel;uye avhareji yepore dhayamita inopfuura makumi mana kusvika makumi mashanu angstroms inonzi coarse pore silica gel.

Liquid silicone process sumo

Liquid silica gel inoshandiswa muindasitiri kudzikisa mvura yesodium kuita silica sol kuburikidza neiyo ion exchange.Imvura inopenya yemukaka ine kugadzikana kwepamusoro.Iyo sirika silica gel inova inoputika yakasimba mushure mekuoma.Semuenzaniso, mukugadzirira kwe (phosphorus-molybdenum-niobium-oxygen)/silica catalyst yekugadzirira acrylonitrile neoxidative oxidation yepropylene, mhinduro ine zvikamu zvinoshanda zvinosanganiswa ne silica sol, uye microspheres inogadzirwa nespraying catalyst.
