Kuenzanisa Ongororo yeKurapa Dhigirii Yekuyedza Nzira dzeSilicone Dzvinyiriro-Sensitive Adhesives naJiangsu. PTFE High-Temperature Fabric Manufacturers
(Solvent Extraction Method, DSC Method & FTIR Method)
I. Misimboti Yekuyera uye Misiyano Yakakosha
Iyi nzira inoyera gel content. Samples inodzokororwa yakabudiswa ne good solvent; mamorekuru asina kubatanidzwa anonyungudika. Iyo yakaomeswa yakasara inoyerwa kuverengera huwandu hwehuwandu hwezvinhu zvisinganyungudika, zvichiratidza chikamu che macro insoluble network chimiro.
2. DSC Nzira
Iyi nzira inoyera yasara reaction heat. Iyo yakazara kupisa kuburitswa kwemasampuri asina kupora (ΔHtotal) uye yakasara kupisa kuburitswa kwebvunzo samples (ΔHresidual) inoyerwa zvichiteerana. Kurapa dhigirii: α = 1−ΔHresidual / ΔHtotal Iyo inoratidza chikamu chezvakasara reactive zvinoshanda mapoka.
3. FTIR Spectroscopy Method
Iyi nzira inotarisa kushandiswa kwemaitiro anoshanda mapoka. Kune masisitimu ehydrosilylation, peak nzvimbo kusiyana kweSi-H (≈2160 cm⁻⊃1;) kana Si-Vi (≈1595 cm⁻⊃1;) inoteverwa. Iyo yemukati mwero peak (semuenzaniso, Si-CH₃ pa ≈1260 cm⁻⊃1;) inogamuchirwa kuti ive yakajairwa, ichipa zvakananga chiyero chekutendeuka chechaiwo chemakemikari bond.
II. Kuenzanisa Kwakarurama uye Zvikanganiso Zvikuru
Zvikamu zvecheni zvisina kubatwa zvakabatwa nekupinzwa kwemuviri uye kukiya kwetopological zvinozivikanwa zvisirizvo se 'crosslinked chimiro', zvichitungamira kune yakarongeka overestimation yekemikari yekurapa degree. Kunze kwezvo, mhedzisiro yebvunzo inokanganiswa nekuparara kwekushanda, microgel kurasikirwa uye kushanduka kwemamiriro ekushanda, nekunyatso ± 2-5%.
2. DSC Nzira
Inopa huchokwadi hwepamusoro pamitengo yekushandura yakaderera-kusvika-yepakati. Nekudaro, pamadhigirii ekurapa akakwira, mapoka anoshanda akasara haakwanise kuita zvizere nekuda kwekuganhurwa kwekupararira, zvichikonzera kudzikira kwakayerwa kupisa kuburitswa uye kwakakosha overestimation yekurapa degree. Zvimwe zvikanganiso zvinobva pakusarudzwa kwekutanga, maitiro emativi uye kutsunga kwe ΔHtotal. Kudzokorora kwayo kwakanaka (<±2%).
3. FTIR Nzira
Iyo inocherekedza zvakananga chemikemikari chisungo shanduko uye inozvirumbidza yakanyanya kuenderana neiyo chaiyo kemikari kutendeuka. Mhosho huru dzinobva mukudhumana kwepamusoro (semuenzaniso, kukanganiswa kwemhute yemvura pazviratidzo zveSi-H). Iyo ATR modhi inongoona mativi epamusoro; bvunzo data ichakanganiswa kana kurapa kufanana kwakasiyana pakati pepamusoro nemukati. Chiyero chinoenderana neLambert-Beer Law uye chinovimba nemasamples asina kubatwa. Inoratidza kurongeka kwepamusoro kweanenge ± 1-3%.
III. Yakakwana Kururama Chinzvimbo
Inotongwa nedhigirii chaiyo yekushandura yemakemikari zvisungo , kutevedzana kwechokwadi ndeichi: FTIR Method > DSC Method (yakaderera-kusvika-yepakati shanduko yerudzi) > Solvent Extraction Method
Solvent Extraction Method Yakaderera nemazvo. Huwandu hwekuyedza hunokwidziridzwa nekuda kwezvipo zvemuviri uye zvinoratidza kurongeka kwakanyanya nemakemikari crosslinking chimiro. Zvakadaro, mhedzisiro yayo iri padyo nekuita sevhisi kuita mumaindasitiri ekushandisa.
DSC Method Inovimbika uye yakarurama pasi peyakaderera-kusvika-yepakati kutendeuka mitengo. Inogona kuburitsa manyepo ekurapa madhigirii ekuverengera mukati mematunhu anodzorwa-anodzora, saka haizoshandiswe yakazvimirira kuongorora masisitimu akarapwa zvakanyanya.
FTIR Method Yakanyanya kurongeka, inokwanisa kusiyanisa zvakanaka kemikari shanduko, kunyanya yakakodzera kusiyanisa pasi pepakati-kusvika-yakakwirira kutendeuka mitengo.
IV. Zvinoshanda Zvinokurudzira
Solvent Extraction Method Inokodzera kuongororwa kwemhando yekukurumidza kuona kana gel yemukati inosangana nezvinodiwa sevhisi. Kuverenga kwayo hakufanirwe kuenzana zvakananga nekemikari crosslink density.
DSC Nzira Inoshanda kune reaction kinetics tsvakiridzo uye maitiro ekutarisa. Kuchenjerera kuchabhadharwa pakutsauswa kwechiyero panguva dzekutendeuka kwepamusoro. Kuedzwa kwakabatana neFTIR Method inokurudzirwa.
FTIR Method Yakasarudzika nzira yekuenzanisa yeR&D naJiangsu PTFE vanogadzira machira epamusoro-tembiricha. Inogona kumisa zvakananga maitiro ekuchinja kwemakemikari mareti ekuvandudza fomula uye maitiro ekugadzirisa. Yakasanganiswa neDSC kuyedzwa, inopa ruzivo rwekuwedzera pakurapa kufambira mberi.
Zviri pamusoro apa zvinopihwa ne Jiangsu Aokai New Material Technology Co., Ltd.
Kana iwe uchida kudzidza zvakawanda zvakatsanangurwa, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvezvizere-range zvigadzirwa zvinosanganisira PTFE high-temperature machira, PTFE yakakwirira-temperature adhesive matepi, PTFE high-temperature mesh mabhandi, seamless fusing muchina mabhandi, single-sided PTFE machira, high-temperature resistant fiberglass, high-temperature resistant ndapota taura nesu kuburikidza nenzira dziri pasi apa:
