Mphete yosindikiza ya silicone ndi mtundu wa mphete yosindikiza.Amapangidwa ndi gel osakaniza a silika ndipo amagwiritsidwa ntchito kukonza chivundikiro cha annular kuti chigwirizane ndi kusiyana pakati pa ferrule kapena gasket pachovala.Ndizosiyana ndi mphete yosindikiza yopangidwa ndi zipangizo zina.Kuchita kwa madzi kukana kapena kutayikira kumakhala bwinoko.Pakalipano, amagwiritsidwa ntchito makamaka posindikiza madzi ndi kusunga zofunikira za tsiku ndi tsiku monga crisper, mpunga wophika, madzi operekera madzi, bokosi la masana, chikho cha magnetized, mphika wa khofi, ndi zina zotero. Ndizosavuta kugwiritsa ntchito, zotetezeka komanso zachilengedwe, ndipo ndizozama kwambiri. kukondedwa ndi aliyense.Chifukwa chake lero, tiyeni tiwone mozama mphete yosindikizira ya silicone.
Kusiyana pakati pa mphete yosindikiza ya silikoni ndi mphete zina zosindikizira:
1. Zabwino kwambiri kukana nyengo
Kukana kwanyengo kumatanthawuza mndandanda wa zochitika zokalamba monga kutha, kusinthika, kusweka, choko ndi kutaya mphamvu chifukwa cha mphamvu zakunja monga kuwala kwa dzuwa ndi kusintha kwa kutentha.Ma radiation a ultraviolet ndiye chinthu chachikulu chomwe chimalimbikitsa kukalamba kwa mankhwala.Chomangira cha Si-O-Si mu mphira wa silikoni chimakhala chokhazikika ku mpweya, ozoni ndi cheza cha ultraviolet, ndipo chimakhala chokana kwambiri pakukokoloka kwa ozoni ndi ma oxides.Popanda zowonjezera, zimakhala ndi nyengo yabwino yotsutsa, ngakhale zitagwiritsidwa ntchito panja kwa nthawi yaitali, sizidzasokoneza.
2. Chitetezo cha zinthu ndi kuteteza chilengedwe
Rabara ya silicone ili ndi mphamvu yake yapadera ya thupi, yopanda poizoni komanso yopanda kukoma, yopanda chikasu komanso yosazirala ikagwiritsidwa ntchito kwa nthawi yayitali, ndipo imasokonezedwa kwambiri ndi chilengedwe.Imakwaniritsa miyezo yadziko lonse ya chakudya ndi ukhondo wamankhwala.Amagwiritsidwa ntchito kwambiri muzakudya, mankhwala, phala la siliva la aluminium ndi mafuta osiyanasiyana.kalasi zonyansa zosefera zayatsidwa.
3. Ntchito yabwino yotchinjiriza magetsi
Silicone ya silicone ili ndi mphamvu zabwino kwambiri zotchinjiriza magetsi, komanso ndiyabwino kwambiri pakukana kwa corona (kutha kukana kuwonongeka kwamtundu) komanso kukana kwa arc (kutha kukana kuwonongeka komwe kumachitika chifukwa champhamvu yamagetsi arc).
4. High mpweya permeability ndi selectivity kwa mpweya kufala
Chifukwa cha kapangidwe ka maselo a silika gel, mphete yosindikizira ya silika imakhala ndi mpweya wabwino komanso kusankha bwino kwa mpweya.Pa kutentha, mpweya permeability wa silikoni mphira mpweya, nayitrogeni, mpweya, carbon dioxide ndi mpweya wina ndi 30-50 nthawi apamwamba kuposa mphira zachilengedwe.nthawi.
5. Hygroscopicity
Mphamvu ya pamwamba ya mphete ya silikoni ndi yochepa, yomwe imakhala ndi ntchito yoyamwitsa ndi kuteteza chinyezi m'chilengedwe.
6. Kuchuluka kwa kutentha kwakukulu ndi kutsika kwa kutentha
(1).Kukana kutentha kwakukulu:Poyerekeza ndi mphira wamba, mphete yosindikizira yopangidwa ndi silika gel imakhala ndi kutentha kwabwino, ndipo imatha kutenthedwa pa kutentha kwakukulu popanda kupunduka komanso popanda kupanga zinthu zovulaza.Ikhoza kugwiritsidwa ntchito pafupifupi kwanthawizonse pa 150 ° C popanda kusintha kwa ntchito, ingagwiritsidwe ntchito mosalekeza pa 200 ° C kwa maola 10,000, ndipo ingagwiritsidwe ntchito pa 350 ° C kwa kanthawi.Amagwiritsidwa ntchito kwambiri pazochitika zomwe zimafuna kukana kutentha, monga: mphete yosindikizira ya botolo la thermos.
(2).Kutsika kwa kutentha:Rabara wamba idzakhala yolimba komanso yonyeka pa -20 ° C mpaka -30 ° C, pamene mphira wa silikoni umakhalabe ndi mphamvu yabwino pa -60 ° C mpaka -70 ° C.Ena mwapadera mphira silikoni Imathanso kupirira kutentha kwambiri kotsika kwambiri, monga: mphete zomata za cryogenic, zotsika kwambiri zimatha kufika -100 ° C.
Kuipa kwa zisindikizo za mphira za silicone:
(1).Zochita zamakina zamphamvu zamakokedwe ndi kugwetsa mphamvu ndizosauka.Sitikulimbikitsidwa kugwiritsa ntchito mphete zosindikizira za silicone kuti zitambasule, kung'amba, komanso kuvala mwamphamvu pamalo ogwirira ntchito.Kawirikawiri, amagwiritsidwa ntchito posindikiza static.
(2).Ngakhale mphira wa silikoni umagwirizana ndi mafuta ambiri, mankhwala ndi zosungunulira, ndipo uli ndi asidi wabwino komanso kukana kwa alkali, sulimbana ndi alkyl hydrogen ndi mafuta onunkhira.Chifukwa chake, sizoyenera kugwiritsidwa ntchito m'malo omwe mphamvu yogwira ntchito imaposa mapaundi 50.Kuphatikiza apo, sikulimbikitsidwa kugwiritsa ntchito zisindikizo za silikoni muzosungunulira zambiri, mafuta, ma acid acids komanso njira zothira caustic soda.
(3).Pankhani ya mtengo, poyerekeza ndi zida zina, mtengo wopangira silicone wosindikiza mphete ya rabara ndi wokwera kwambiri.
