Mu Field Of Organic Silicon, zida za mphira za silicon zotsika zimatha kugawidwa kukhala zolimba komanso zamadzimadzi, ndipo zida zonsezi zimagwiritsidwa ntchito kwambiri m'mafakitale akuluakulu osiyanasiyana, monga guluu wagalasi, madzi a organic silikoni, ndi kusindikiza zinthu za silicon Rubber, zamagetsi. kusindikiza zowonjezera, ndi zina zotero. Pali zofanana zambiri pakati pa minda yawo yogwiritsira ntchito ndi katundu wakuthupi, ndipo njira zawo zopangira ndizosiyana.M'munda wazinthu, maudindo awo ndi ntchito zake ndizofanana.Kodi pali kusiyana kotani pakati pa zinthu ndi zinthu?

Kusiyana kwakukulu pakati pa gel osakaniza a silika ndi gel olimba a silica ndi: imodzi ndi yamadzimadzi ndipo ina ndi yolimba;koma pambuyo pokonza zomalizidwa, ziwirizi sizili zophweka kusiyanitsa.Geli ya silica yamadzimadzi ndi yamadzimadzi ndipo imakhala ndi madzi.Geli yolimba ya silica ndi yolimba ndipo ilibe madzi.

Magawo osiyanasiyana ogwiritsa ntchito:
(1) Silicone yamadzimadzi nthawi zambiri imagwiritsidwa ntchito popanga zinthu za ana, zinthu zakukhitchini za silikoni ndi mankhwala azachipatala, zimatha kulumikizana mwachindunji ndi chakudya ndi thupi la munthu;

(2) Gelisi yolimba ya silica imagwiritsidwa ntchito pazinthu zatsiku ndi tsiku, magawo osiyanasiyana a mafakitale ndi zida zamagalimoto;

(3) Chitetezo cha gel osakaniza amadzimadzi ndi gelisi yolimba ya silica: Gelisi yamadzimadzi yamadzimadzi ndi yowonekera kwambiri, yotetezeka kwambiri pazakudya.Palibe zida zothandizira monga vulcanizing agent zomwe zimawonjezedwa panthawi yakuumba.Zida zosindikizira zimapangidwa ndi kusindikiza.

Geli yolimba ya silika ndi chinthu chowoneka bwino.Vulcanization ndiyofunikira kuti ifulumizitse nthawi yochiritsa.

Kuumba:

Liquid Silicone (LSR): Dzina lonse ndi jakisoni wopangira mphira wamadzimadzi a silicone, ndipo zida zavulcanization ndi makina omangira jekeseni.Makina opangira jekeseni ndi ophweka kwambiri, kulondola kwa mankhwala ndikwambiri, ndipo zotulukapo ndizokwera (gulu la A / B limasakanizidwa kwa masekondi pang'ono pa kutentha kwina).Zidazo zimasakanizidwa ndikuwonjezeredwa ndi guluu wamtundu komanso chothandizira kuti chizilowetsa mu nkhungu popanda ntchito yamanja.Ubwino wazinthu Zogulitsazo zimakhala ndi madzi abwino, kutambasula mwamphamvu komanso kulimba mtima, ndipo nkhungu imaphatikizana ndi jekeseni wa jekeseni, kotero mankhwalawa ali ndi doko la jekeseni wa pulasitiki ndipo alibe mizere yolekanitsa pamwamba.

Silicone Yolimba: Zopangira zopangira silika gel olimba ndizolimba.Pambuyo poti wopanga mphira wa silicone atasakanizidwa ndi chosakanizira, amafunika kuwonjezera guluu wamtundu ndi chothandizira, kenako ndikudula mu kukula koyenera ndikuyika pawokha mu nkhungu kuti apange ndikuchiritsa.Njira yodzipangira yokha imafuna ntchito yamanja kuti itenge nkhungu ndikutulutsa zinthuzo.Chifukwa chakuti zinthuzo ndi zolimba, kusungunuka kwa madzi ndi kutambasula kumakhala kochepa kwambiri kuposa kwamadzimadzi.Chogulitsacho chilibe doko la jakisoni, ndipo chomalizidwa chokonzedwa chimakhala ndi mizere yolekanitsa yamtunda ndi yotsika.

Kodi Pali Kusiyana Kotani Pakati pa Liquid Silicone Ndi Solid Silicone Materials?
Gelisi yolimba ya silika imapangidwa ndi galasi lamadzi (sodium silicate) ngati chopangira, chopangidwa ndi hydrolyzed mu sing'anga ya asidi kuti apange gel, kenako amapangidwa kukhala gel osakaniza ndi ukalamba, kutsuka, kuyanika, etc., kutengera madzi, zowonekera kapena zoyera zolimba.Zogulitsa pamsika zimakhala ndi ma gels a silika osakhazikika, ozungulira, komanso ang'onoang'ono, omwe nthawi zambiri amagwiritsidwa ntchito ngati chothandizira kuti pakhale vulcanization pamabedi amadzimadzi.

awiri.Akagwiritsidwa ntchito ngati chonyamulira chothandizira, gel osakaniza a silika nthawi zambiri amamizidwa mu njira yomwe ili ndi zigawo zogwira mtima, kotero kuti yankho limalowa mu pores za gel silika, ndipo zigawo zogwira ntchito zimagawidwa pamwamba pa silika.Gelation kudzera kuyanika, kutsegula, etc. The pore dongosolo la silika gel osakaniza ali ndi chikoka pa zimatha anakonza amapereka chothandizira, monga pore voliyumu ndi pore kukula kugawa silika gel osakaniza.Nthawi zambiri, gelisi ya silika yokhala ndi pore m'mimba mwake ya zosakwana 15 mpaka 20 imatchedwa gel osakaniza a pore;ndipo pafupifupi pore m'mimba mwake kuposa 40 mpaka 50 angstroms amatchedwa coarse pore silica gel.

Liquid silikoni ndondomeko chiyambi

Gelisi yamadzimadzi ya silika imagwiritsidwa ntchito m'mafakitale kuti iwononge madzi a sodium mu silika sol kupyolera mu kusinthana kwa ion.Ndi translucent yamkaka woyera madzi ndi mkulu bata.Gelisi yolimba ya silica imakhala yolimba poyanika pambuyo poyanika.Mwachitsanzo, pokonzekera (phosphorous-molybdenum-niobium-oxygen)/silika chothandizira pokonzekera acrylonitrile ndi okosijeni oxidation wa propylene, yankho lomwe lili ndi zigawo zogwira ntchito limasakanikirana ndi silika sol, ndipo ma microspheres amakonzedwa ndi kupopera mankhwala chothandizira.
