Silicone chubu ndi mtundu wa mphira wokhala ndi katundu wambiri komanso wabwino wokwanira.Imakhala ndi ntchito yabwino kwambiri yotchinjiriza magetsi, kukana kukalamba, kukhazikika kwa mankhwala, kukana kwa okosijeni ndi kukana kwa nyengo, kukana kwa radiation, physiological inertia, mpweya wabwino, komanso kukana kutentha kwambiri komanso kutsika.Itha kugwiritsidwa ntchito mu -60 ℃～250 ℃ pakugwiritsa ntchito nthawi yayitali.Choncho, amagwiritsidwa ntchito kwambiri mu ndege, zamagetsi, petroleum, makampani mankhwala, makina, zipangizo zamagetsi, mankhwala, uvuni, chakudya ndi mafakitale ena amakono, makampani chitetezo ndi zofunika tsiku ndi tsiku.
Silicone chubu imapangidwa ndi mphira ya silikoni yaiwisi yaiwisi yowonjezeredwa ku chosakanizira cha raba chopiringizira kapena chopopera chopanda mpweya, ndipo kaboni woyera wakuda ndi zina zimawonjezeredwa pang'onopang'ono kuti ziyeretsedwe mobwerezabwereza komanso mofanana.Malinga ndi miyezo yaukadaulo yamakampani, mankhwalawa amapangidwa ndi extrusion.
Gulu
Machubu wamba a silikoni ndi awa: chubu cha silikoni chachipatala, chubu cha silicone cha chakudya, chubu cha silikoni yamafakitale, chubu chowoneka bwino cha silikoni, zida zamachubu za silicone.
Machubu a silikoni azachipatala amagwiritsidwa ntchito makamaka ngati zida zachipatala, ma catheters azachipatala, ndikutengera kapangidwe ka antibacterial kuti atsimikizire kugwiritsidwa ntchito kotetezeka.
Machubu a silicone omwe ali ndi chakudya amagwiritsidwa ntchito popangira madzi, mapaipi opatulira makina a khofi, komanso chitetezo chamzere wopanda madzi pazida zapakhomo.
Machubu a silikoni aku mafakitale amagwiritsidwa ntchito ngati mankhwala apadera, magetsi ndi zida zina zapadera zotetezera zachilengedwe, pogwiritsa ntchito silikoni yapadera.
mawonekedwe aukadaulo
1. Kuuma: 70 ± 5, mphamvu yokhazikika: ≥6.5.
2. Mtundu wa mankhwala: wowonekera, woyera, wakuda, wofiira, wachikasu, wobiriwira (akhoza kupangidwanso popempha).
3. Kutentha kukana osiyanasiyana: -40–300 ℃.
4. Kukula: caliber 0.5-30MM.
5. Kapangidwe kapamwamba: Sesa madzi, osamamatira kuzinthu zambiri, ndipo amatha kutenga gawo lodzipatula.
6. Mphamvu zamagetsi: Zikakhala ndi chinyezi kapena madzi kapena kutentha kumakwera, kusintha kumakhala kochepa, ngakhale kuyaka mufupipafupi.
7. Silicon dioxide yopangidwa ikadali insulator, yomwe imatsimikizira kuti zipangizo zamagetsi zikupitirizabe kugwira ntchito, choncho ndizoyenera kwambiri kupanga mawaya, zingwe, ndi mawaya otsogolera.
mawonekedwe a magwiridwe antchito
① Kugwiritsa ntchito mosalekeza kutentha osiyanasiyana: -60 ℃ ~ 200 ℃;
②Yofewa, yosamva arc komanso yosamva corona;
③ Zosiyanasiyana zitha kusinthidwa malinga ndi zomwe makasitomala amafuna.
④Zopanda vuto, zopanda poizoni komanso zopanda kukoma
⑤Kuthamanga kwambiri, kuteteza chilengedwe
Mawonekedwe
Rabara ya silicone ndi mtundu watsopano wa zinthu zotanuka za polima, zomwe zimakhala ndi kutentha kwapamwamba kwambiri (250-300 ° C) ndi kutsika kwa kutentha (-40-60 ° C), kukhazikika kwa thupi, ndipo kumatha kupirira mikhalidwe yovuta mobwerezabwereza.Ndipo zinthu zophera tizilombo toyambitsa matenda, zolimba kwambiri komanso mapindikidwe ang'onoang'ono okhazikika (maola 200 ℃ 48 zosakwana 50%), magetsi owonongeka (20-25KV/mm), kukana kwa ozoni, kukana kwa UV.Kukana kwa radiation ndi mawonekedwe ena, mphira wapadera wa silikoni uli ndi kukana kwamafuta.
ntchito
1. Mayendedwe: amagwiritsidwa ntchito popanga zombo.
2. Wailesi ndi mota: m'makampani opanga ma telecommunications.
3. Amagwiritsidwa ntchito m'makampani opanga zida ndi zida.
4. Kugwiritsa ntchito makampani oyendetsa ndege.
5. Oyenera zipangizo zapakhomo, kuunikira, chithandizo chamankhwala, kukongola ndi zipangizo zopangira tsitsi, etc.
Kusiyanasiyana ndi chitoliro cha PVC
Silicone chubu ndi mtundu wa chubu la mphira, lomwe siligwira mafuta komanso limalimbana ndi kutentha.Machubu a mphira ali ndi ntchito zambiri chifukwa cha mitundu yosiyanasiyana ya mphira.Zida zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala ndi EPDM, CR, VMQ, FKM, IIR, ACM, AEM, ndi zina zotero. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala zosanjikiza imodzi, zosanjikiza ziwiri, zosanjikiza zambiri, ndi zolimbikitsidwa, zosasinthika, ndi zina zotero.
Choyamba, silika gel osakaniza ndi zinthu mphira, PVC ndi zinthu pulasitiki, chuma PVC chitoliro ndi polyvinyl kolorayidi, ndi zopangira silikoni chitoliro ndi pakachitsulo woipa.
1. PVC chitoliro chapangidwa ndi polyvinyl kolorayidi utomoni, stabilizer, lubricant, etc., ndiyeno extruded ndi otentha-atolankhani jekeseni akamaumba makina.Ntchito yaikulu, kutchinjiriza magetsi;kukhazikika kwamankhwala kwabwino;kudzizimitsa;mayamwidwe otsika madzi;zosavuta kumamatira Connection, akhoza kupirira kutentha kwa pafupifupi 40 °.Zida zazikuluzikulu ndi gasi wamakampani, zoyendera zamadzimadzi, ndi zina zotero, mapaipi otayira m'nyumba, mapaipi amadzi, ndi zina zotero. Nkhani zoteteza chilengedwe: Zida zazikulu zothandizira monga mapulasitiki ndi anti-aging agents omwe amawonjezeredwa ndi poizoni.Mapulasitiki omwe amagwiritsidwa ntchito tsiku ndi tsiku a PVC amagwiritsa ntchito dibutyl terephthalate, dioctyl phthalate, ndi zina zotero. Mankhwalawa Mankhwalawa ndi oopsa.
2. Silicone chubu, zinthu za silikoni zimakhala ndi mankhwala okhazikika, sizigwirizana ndi mankhwala aliwonse kupatulapo alkali amphamvu ndi hydrofluoric acid, zimakhala ndi mankhwala abwino, zimakhala ndi mphamvu zamagetsi, zimakhala zosavuta kukalamba komanso nyengo, zinthu zofewa, zachilengedwe. ndi zinthu zopanda poizoni, Zopanda mtundu komanso zopanda fungo.Mapaipi apakhomo adzapangidwa ndi zinthu za silikoni, zomwe zimagwiritsidwa ntchito kwambiri pazida zam'nyumba, mafakitale azachipatala, mafakitale, mafakitale amagalimoto ndi zina zotero.
Mbali yaikulu ya payipi silikoni ndi kugonjetsedwa ndi kutentha kusintha kuchokera -60 madigiri 250 madigiri, koma mtengo ndi okwera mtengo kwambiri.PVC nthawi zambiri amagwiritsidwa ntchito ngati mapaipi wamba amadzi, omwe amakhudzidwa ndi kutentha, otsika mtengo komanso onunkhira, oyenera malo ogwirira ntchito, ndipo alibe zofunikira pa hoses.Machubu a silikoni osagwira ntchito amatha kupirira kukakamizidwa, koma PVC ndi pafupifupi, kutengera makulidwe a khoma ndi mawonekedwe.Izi ndizosiyana pakati pa machubu a silicone ndi machubu a PVC.
