Chivharo chekuvaka cheSilicone chinomiririra hunyanzvi hwepamusoro hwesainzi yezvinhu mukuvaka, chakagadzirwa kugadzirisa zvinodiwa zvakakosha zvekushanda izvo zvivharo zvechinyakare zvisingagoni kusangana nazvo. Sepolymer inoshanda zvakanyanya, inopa mashandiro asina kujairika ekuchengetedza chimiro, kudzivirira mamiriro ekunze, uye kurarama kwenguva refu.
Kuumbwa uye Maitiro
Zvakagadzirwa kubva kumapolymers esilicone akasimbiswa ne silica, izvi zvinonamira ne acetoxy kana neutral mechanisms kuita ma elastomers akasimba uye anochinjika. Hunhu hukuru hwemamorekuru hunosanganisira:
1.Siloxane musana inopa kugadzikana kweUV uye kuramba kupisa
2. Mapoka anoshanda zvakanaka anogonesa kunamatira kwe substrate
3. Zvekuwedzera zvepamusoro (fungicides, adhesives) zvinosimudzira mashandiro
Zvakanakira Kushanda Kwakakosha
1. Nzvimbo yekufamba kwechivakwa
- Inochengetedza hutano hwayo kuburikidza nekufamba kwemajoini kwe±50% (ASTM C920 standards), ichidzivirira kuputsika kwestress muzvinhu zvinoshanduka zvekuvaka.
2. Kutsungirira Zvakanyanya Kwemamiriro Ekunze
Inoshanda kubva pa -73°C kusvika +260°C pasina kuora kwethermoplastic, ichikunda dzimwe nzira dze organic polymer.
3.Dziviriro yeEmbavhoro yeKuvaka
Inogadzira zvipingamupinyi zvinoramba zvichidzivirira mvura, zvakakosha kune:
- Masisitimu emadziro emaketeni
- Masisitimu ekuwedzera majoini
- Zvishandiso zvekuvhara denderedzwa
4. Kuenderana kwezvinhu
Inoshanda zvinobudirira kune substrates dzakasiyana-siyana dzinosanganisira:
Girazi | Aruminiyamu Inozorwa | Konkriti | Granite | PVC Pasina kukonzera ngura ye galvanic kana kuora kwenzvimbo.
5. Hutsanana hwekushanda
Mafomula ane chitupa cheNSF anodzivirira kukura kwehutachiona munzvimbo dzakanyorova (nzvimbo dzakatenderedza dziva, nzvimbo dzekugadzira chikafu).
Gwaro reKutsanangurwa kweUnyanzvi
| Pfuma | Rudzi rweAcetoxy | Rudzi Rwakasiyana-siyana |
|---|---|---|
| Maitiro Ekurapa | Acetic Acid | Doro/Ketoxime |
| Kuenderana kweSubstrate | Kwete simbi | Zvinhu zvese |
| Tembiricha Yebasa | -50°C kusvika 180°C | -73°C kusvika 260°C |
| Kukwanisa Kufamba | ±25% | ±50% |
Protocol yeMashandisirwo Einjiniya
1. Kugadzirira Pamusoro
Kuchenesa zvinonyungudutsa (isopropyl alcohol)
Kukwesha panzvimbo dzisina maburi
Kushandiswa kwekutanga kwechirongwa kwakatarwa
2. Kunyatsogadzirisa Kuiswa
Kuiswa kwetsvimbo yemusana yemajoini >6mm
Kona yemuromo we45° pakumanikidzwa kwakasimba
Kugadzirisa mukati memaminitsi gumi mushure mekushandisa
3. Sainzi Yekurapa
Kuumbwa kweganda: maminetsi gumi nemashanu kusvika makumi matatu
Kurapwa kwakazara: maawa 24-72 (zvichienderana nekudzika kwechirwere)
Mhedzisiro yekukurumidzira hunyoro
Kutevedzera Mutemo
Mafomula anotungamira anosangana:
Zvinodiwa zveASTM C920 Kirasi 100/50
Kurongwa kweISO 11600 F&G
LEED v4.1 zvinhu zvakakosha
