Sankhani chilankhulo Silika rabar ndiye gulu lalikulu kwambiri pakati Zogulitsa za Organic . Ndiosamwa Si-o-si Magulu akuluakulu ndi organic amagulu a organic, kuphatikiza onse azorganic ndi okhazikika.
Poyerekeza ndi wamba Ourction Ourbers, silika rabar ali ndi zabwino kukana kutentha, Kukana Kwambiri, Kutulutsa kwamagetsi, Kukhazikika kwa mankhwala , ndipo Chizindikiro cha thupi , kupangitsa kuti ikhale yogwiritsidwa ntchito kwambiri zamagetsi, zamagetsi, maotayi, chakudya, banja , ndipo Zogulitsa zopumira mafakitale.
1. Kutentha kwambiri kwa silika
Silika rabar imakhazikitsidwa kutentha kwambiri (htv) ndi chipinda-kutentha (RTV) Mitundu. A Rabaicinene rabar ikhoza kugawidwa machiritso ndi kuwonjezera-kuchiritsa machitidwe.
Htv silicane rabar imagwiritsidwa ntchito kuti apange osiyanasiyana ziwalo za rabara , monga mphete zopindika, gaskets, chinsinsi cha chinsinsi, Keyboard imayendetsa tinthu tating'onoting'ono , ndipo machubu azachipatala.
Motsutsana, Rabaicinene rabar nthawi zambiri amagwiritsidwa ntchito ngati phitsa, Mankhwala ophika , kapena zida zopangidwa ndi nkhungu , ena mwa ntchito Zosagwirizana ndi mphira pambuyo pake kukonza kapena zoteteza.
Htv silicane rabar zimaphatikizapo mitundu ingapo: methyl silicrone rabara (mq), methyl vinyl silicrane (vmq, ogwiritsidwa ntchito kwambiri) , ndipo methyl vinyl phenyl silicrone rabara (pvmq) , kudziwika chifukwa cha zabwino kutentha kotsika ndi kukana kwa radiation.
Mwa iwo, Vmq ili ndi maunyolo ochepa a Vinyl mbali, kulimbikitsa kufooka. Itha kugwiritsa ntchito zosiyanasiyana Percoxide Kuchiritsika Othandizira komanso bwino bwino kukakamiza kukhazikika , katundu wovuta magwiridwe antchito apamwamba a mphira monga Mphete ndi Kusindikiza Magesi.
Izi zikuwonetsa bwino mawonekedwe, mawonekedwe osalala, komanso opaleshoni yosavuta, ndikupangitsa kukhala imodzi mwazomwe zimagwiritsidwa ntchito kwambiri Ruble rubrs mumsika.
1.1 zoyambitsa chikasu mu silika rabar
Popanga zenizeni Htv silicane rabar , a Chiwirichi njira nthawi zambiri imafunikira kuchotsa zotsalira za peroxide ndi kuchuluka Kutaya Mtima , potero amalimbikitsa mphamvu yamakina ndi bata wa ziwalo za rabara.
Komabe, panthawiyi, zina Zinthu za mphira zitha kuwonetsa chikasu kapena kutsika kuwonekera , mwachindunji amakhudza ntchito yawo mu mafakitale apamwamba kwambiri monga chakudya, wacipatala , ndipo dzuwa la solar magawo.
Kafukufuku akuwonetsa kuti zomwe zimayambitsa chikasu zimaphatikizapo:
Kufufuza Zinthu Zachitsulo kapena nitrate ma iyoni (No₃⁻) Mu chingamu chosaphika kapena zowonjezera, zomwe zimayambitsa chikasu pakuchiritsa;
Peroxide kuwonongeka kupanga acetone , zomwe zimatsogolera α-hydroxybutyralyeyde kufupika ndi Kuphatikizira kwa mapangidwe;
A pH mulingo wa Manja a Sinayi kukopa kwakukulu chikasu.
Chifukwa chake, kusintha njira zambiri zimangoyang'ana ram gum, Manja a Sinayi , ndipo zowonjezera.
1.2 miyeso yosintha chikasu
Ofufuzawo apanga angapo Njira Zotsutsa Zachikasu , monga:
Ogwilizitsa Mafuta a Silicted Sicone zomwe zimachitika ngati onse a Kulowerera Co-Officing ndi Mtumiki wachikasu Pamavuto, kulepheretsa kusinthasintha komwe kumathamangira kuthamanga;
Kugwilitsa nchito Tyte-mtundu bis (2,5-peroxide) othandizira ndi okhazikika okhazikika kuti atuluke kwambiri ziwalo za rabara ; (https://www.sunlitek.com/)
Kuyambitsa organic surfactonts pamene Mankhwala a Silika kuwongolera kukula kwa tinthu ndikusintha kupezeka;
Kuwonjezera Zowonjezera za Pyrophasphate zodziwika bwino , zomwe zimapangitsa kuti magwiridwe antchito achikasu osakhala chete katundu wa mphira.
Zolemba izi sizingosintha mawonekedwe abwino wa Zinthu za mphira , komanso kuwonjezera kukonza kukhazikika wa Zosagwirizana ndi mphira mukamafooketsa komanso nthawi yachiwiri.
2. MALANGIZO
Zaka zaposachedwa, China Makampani opanga silican wapanga mwachangu, ndi Kupanga kwa Monomerier Kufikira kukongola. Mabizinesi akuluakulu akusintha mapangidwe apamwamba ndi Zogulitsa za Silicle.
Ziwalo za rabara akhala nthambi yovuta ya Zogulitsa za mphira , kuyika kwambiri mu maotayi, kumanga, zamagetsi, wacipatala , ndipo mphamvu yatsopano mafakitale.
Pakalipano, Zosagwirizana ndi mphira akugwiritsidwa ntchito kwambiri chosangalatsa, kusindikizidwa , ndipo Kudzaza kapangidwe Ntchito, ndikupanga ulalo wosafunikira mu Silicone mphira wopanga.
Monga momwe magwiridwe antchito awonekera ndikupitilizabe kukwera, kupewa chikasu ndi kusamalira kuwonekera ndi bata mu Zinthu za mphira asandulika njira zamakono zoyendetsera zinthu zakuthupi ndikugwiritsa ntchito rabar rabaji.
Silika rabar ndiye gulu lalikulu kwambiri pakati Zogulitsa za Organic.
