RTV2 nkhungu mphira wamadzimadzi silikoni wamitundu yosiyanasiyana yokongoletsera makandulo

Kufotokozera mwachidule:

Kutentha kogwira ntchito kwa silicone yamadzimadzi nkhungu
Kutentha kogwira ntchito kwa silicone nkhungu yamadzimadzi kuli pakati pa -40 ℃ ndi 250 ℃

Kutentha kwamapangidwe azinthu za silicone zamadzimadzi kumatsimikiziridwa kutengera zomwe zimapangidwa.Chipinda kutentha vulcanized silikoni mphira akhoza kugawidwa mu condensation mtundu ndi mtundu kuwonjezera malinga ndi limagwirira vulcanization;imatha kugawidwa m'mitundu iwiri molingana ndi njira yake yopangira: magawo awiri ndi gawo limodzi.Chikhalidwe cha zomangira za silicon-oksijeni zomwe zimapanga unyolo waukulu wa mphira wa silikoni zimatsimikizira kuti mphira wa silikoni uli ndi ubwino womwe mphira wachilengedwe ndi mphira wina alibe.Ili ndi kutentha kwakukulu kogwira ntchito (-40 ° C mpaka 350 ° C) ndipo imakhala ndi kutentha kwambiri komanso kutsika kwa kutentha.

Njira yochepetsera mwachangu zinthu za silicone nkhungu ndi motere

Tip 1. Kusankha kwazinthu: Yesani kusankha zinthu zosalala kuti mupange nkhungu ya master ndi chimango cha nkhungu.Chojambula cha nkhungu chikhoza kupangidwa ndi matabwa a pulasitiki kapena matabwa a acrylic.

Langizo 2. Wotulutsa utsi: Wotulutsa utsi pa nkhungu yayikulu.Zomwe zimatulutsidwa kawirikawiri zimakhala zamadzi, zowuma, ndi mafuta.Nthawi zambiri, zotulutsa zotengera madzi ndi zotulutsa utomoni zimagwiritsidwa ntchito kupanga nkhungu monga mwala wopangidwa ndi konkriti.Gwiritsani ntchito zowuma (zomwe zimatchedwanso kusalowerera ndale), mtundu wa polyurethane gwiritsani ntchito mafuta otulutsa mafuta, ngati nkhungu yaying'ono itatembenuzidwa, mutha kugwiritsanso ntchito sopo kapena sopo m'malo mwake.

Langizo 3: Tsegulani nkhungu mutatha kukhazikika kwathunthu: Popeza njira yochiritsira ya silikoni yamadzimadzi imachokera ku kulimba koyambirira mpaka kukhazikika kwathunthu, anthu ambiri omwe akuyesera kutembenuza nkhunguyo amatsegula nkhunguyo atangolimbitsa koyamba.Panthawiyi, silikoniyo siimakhazikika ndipo imatha kukhala yolimba kwambiri.Ngati wosanjikiza wamkati sanachiritsidwe, kukakamiza nkhungu kutsegula panthawiyi kungayambitsenso mavuto ndi nembanemba yochiritsidwa pang'ono.Choncho, nthawi zambiri tikulimbikitsidwa kutsegula nkhungu pambuyo pa maola 12 mpaka 24.Izi zitha kupewanso vuto la kupunduka kapena kuchuluka kwa nkhungu ya silicone..

Langizo 4: Sankhani silikoni yoyenera: Mukamagwiritsa ntchito silikoni yamadzimadzi kuti muumbe zamanja za epoxy resin, muyenera kusankha silikoni yoyenera.Ngati mukugwiritsa ntchito silicone yamadzimadzi ya condensation ndipo muli ndi zovuta zomata nkhungu, mutha kuyika nkhungu ya silikoni mu uvuni.Kuphika nkhungu pa kutentha kwapakati (80 ℃-90 ℃) kwa maola awiri, kutengera kukula kwa nkhungu silikoni.Kenako, dikirani kuti nkhungu ya silikoni izizire ndikuyika utomoni wa epoxy kuti muthetse vuto la nkhungu kumamatira.Ngati mukugwiritsa ntchito silikoni yowonjezera yamadzimadzi, vuto la nkhungu kumamatira ndikuti nkhungu ya silikoni kapena prototype ya master ndi yoyera mokwanira, kapena kuti pali vuto ndi mtundu wa silikoni kapena utomoni.

Zifukwa zomwe silicone nkhungu siimalimba

Zifukwa zomwe silicone nkhungu siimalimba zitha kukhala chifukwa cha mfundo zitatu izi: 1:

Kutentha ndikotsika kwambiri.Silicone yamadzimadzi imakhala yovuta kulimbitsa pansi pa 10 ° C.Izi nthawi zambiri zimachitika nthawi yozizira.Pankhaniyi, zitha kuthetsedwa mwa kukweza kutentha kwa chipinda kupitirira 20 ℃.

Chiŵerengero chowumitsa ndicholakwika.Nthawi zambiri, chiŵerengero cha gel osakaniza-mtundu wa silika kwa wothandizira ndi 100: 2.Ngati chiŵerengero cha machiritso chomwe chawonjezeredwa ndi chochepa kwambiri, sichidzayambitsa kuchiritsa kapena kuvutika pochiritsa.Kuphatikiza apo, wochiritsa woperekedwa ndi wopanga nthawi zambiri amakhala wolemera kuposa kuchuluka kwa voliyumu.
Gel silikoni ndi mankhwala ochiritsira samasakanizidwa mokwanira.Ngati kusakaniza sikukugwedezeka mofanana, kumapangitsa kuti pakhale kulimba pang'ono ndi kusakhazikika pang'ono.Choncho, poyambitsa, tcherani khutu ku silicone yotsalira pamakona a chidebecho.
