Izinzuzo Eziyinhloko Zokudabuka KwaseShayina I-Desmodur RE
Amandla Okuzibopha Aphakeme Kuzo Zonke Izinto
Ufuna inhlaka yakho isebenze ezindaweni eziningi. Imvelaphi yaseShayina I-Desmodur RE ikunikeza izibopho eziqinile zerabha, i-polyurethane, ngisho nensimbi. Lo mkhiqizo usebenzisa i-ejenti ekhethekile yokuxhumanisa esiza i-glue ukubamba iqine, noma ngabe welula noma ugoba izinto. Uma uyiqhathanisa neminye imikhiqizo, ubona ukuthi i-Desmodur RE evela eShayina ivelele ngamandla ayo aphezulu okuthambekela kanye nokusebenza okuthembekile.
Ukusebenza Okuhlala Isikhathi Eside Ezicelweni Ezidinga Umzamo
Udinga inhlaka yakho ukuze ihlale isikhathi eside, ngisho nasezindaweni ezinzima. I-Desmodur RE igcina amandla ayo ngokuhamba kwesikhathi. Isebenza kahle ezimweni ezishisayo, ezibandayo, noma ezimanzi. Isibonelo, ucwaningo lwasensimini lubonise ukuthi ukugqoka okusebenzisa ubuchwepheshe obufanayo kugcina ukukhanya kwayo okungu-94% ngemva kweminyaka emihlanu esimweni sezulu esibi sasogwini. Lokhu kusho ukuthi ungathemba ukuthi izibopho zakho zizohlala ziqinile, kungakhathaliseki ukuthi uzisebenzisa ezicathulweni, emishinini, noma emishinini yangaphandle.
Ukuguquguquka Kokusetshenziswa Kwezimboni Eziningi
Ungasebenzisa i-China-origin I-Desmodur RE ezimbonini eziningi. Isebenza kumaphrojekthi ezimoto, ifenisha, ezolwandle kanye nezakhiwo. Ithebula elingezansi libonisa ukusetshenziswa okuvamile:
| Isicelo | Kungani Ukhetha I-Desmodur RE? |
|---|---|
| Ama-clearcoats ezimoto | Igcina izimoto zikhanya futhi ivikela elangeni |
| Ukuqedwa kokhuni nefenisha | Ihlala ihlanzekile futhi imelana nokuklwebheka |
| Izimbozo zasolwandle | Ilwa namanzi anosawoti kanye nelanga |
| Izinamathelisi ezibonakalayo | Ihlala icacile kumalensi nezikrini |
| Izindwangu zokwakha | Kugcina izakhiwo zibukeka zintsha |
| Izembozo zokulungisa zezimboni | Kuvikela insimbi ezindaweni ezinzima |
Uthola umkhiqizo owodwa ofanela izidingo eziningi. Lokhu kukongela isikhathi futhi kwenza umsebenzi wakho ube lula.
Indlela iChina edabuka ngayo I-Desmodur RE Inikeza Amandla Okubopha Ahlala Njalo
Ukwakheka Okuthuthukisiwe Kokuxhumanisa Okunqamulelayo
Uthola izibopho eziqinile nezihlala isikhathi eside ngenxa yekhemistri yokuxhumanisa ethuthukisiwe emvelaphi yaseShayina I-Desmodur RELo mkhiqizo usebenzisa i-triphenylmethane-4,4',4''-triisocyanate njengesithako esiyinhloko. Uma uwuxuba nezinamathiselo eziqukethe i-hydroxyl polyurethane noma irabha, wakha inethiwekhi eqinile. Le nethiwekhi ibamba izinto ndawonye, ngisho noma uzinweba noma uzigoba.
Ungathuthukisa ukusebenza ngokulandela izinyathelo zohlelo lokusebenza ezihlakaniphile:
- Bhangqa imvelaphi yaseShayina I-Desmodur RE ngama-polyol anesisindo sama-molecule esiphakathi kuya phezulu. Lokhu kukunikeza ibhalansi efanele phakathi kwamandla nokuguquguquka.
- Sebenzisa inani elincane le-catalyst esekelwe ethini. Lokhu kusiza ukunamathela ngaphandle kokwenza indawo inamathele.
- Faka ama-filler afana ne-calcium carbonate noma i-silica uma ufuna ukushintsha ukugeleza noma wehlise izindleko. Qiniseka ukuthi ama-filler omile ukuze ugweme amabhamuza.
- Gcina zonke izingxenye zomile. Ngisho namanzi amancane angabangela ukugqwala futhi anciphise ukubopha.
Icebiso: Gcina njalo izingxenye zakho zokunamathela endaweni eyomile. Lokhu kugcina ukusabela kokuxhumanisa okuqinile futhi okuthembekile.
Ikhwalithi Ehambisanayo Nokumelana Nomswakama
Ufuna inhlaka yakho isebenze kahle ngaso sonke isikhathi. Imvelaphi yaseShayina I-Desmodur RE ikunikeza imiphumela eqhubekayo ngenxa yokulawulwa kwekhwalithi okuqinile ngesikhathi sokukhiqiza. Uthola futhi ukumelana okuhle komswakama, okubalulekile ezindaweni zangaphandle noma ezimanzi.
Nasi ithebula elibonisa ukuthi ama-isocyanates ahlukene aqhathaniswa kanjani ngokuzwela komswakama:
| I-Isocyanate | Isikhathi se-Gel (25°C, ne-OH Resin) | Ukuzwela komswakama | Isidingo se-Catalyst |
|---|---|---|---|
| I-TDI | imizuzu eyi-10–20 | Phezulu | Phansi |
| I-MDI | imizuzu eyi-15–30 | Phezulu | Okuphansi–Okuphakathi |
| I-HDI | 40–70 amaminithi | Okuphakathi nendawo | Okuphakathi nendawo |
| I-H12MDI | 50–90 amaminithi | Okuphakathi nendawo | Okuphakathi nendawo |
Esivivinyweni sokucwiliswa kwe-asidi samahora angama-24, izinti ezenziwe nge-H12MDI (uhlobo lwe-isocyanate olufana nolwe-Desmodur RE oluvela eShayina) zithole isisindo esingu-3.2% kuphela futhi zahlala zibushelelezi. Izinti ezisekelwe ku-TDI zithole isisindo esingu-12% futhi zaqhekeka. Lokhu kusho ukuthi uthola ukumelana okungcono komswakama kanye nezibopho ezihlala isikhathi eside.
Uvikela futhi impilo yakho kanye nemvelo. I-Desmodur RE evela eShayina inokuqukethwe okuphansi kwe-monomer yamahhala, okunciphisa izingozi zokuphefumula. Ungayisebenzisa ezinhlelweni zamanzi kanye nezingubo eziqinile ukuze unciphise ukukhishwa kwe-solvent.
| Isici | Inzuzo |
|---|---|
| Okuqukethwe kwe-monomer okuphansi kwamahhala | Kunciphisa izingozi zokuphefumula ngesikhathi sokufaka. |
| Ukuhambisana ne-high-solids | Isinyibilikisi esincane = ukukhishwa kwe-VOC okuphansi. |
| Ukusetshenziswa ezinhlelweni zamanzi | Isekela izembozo ezinobungani nemvelo. |
| Imishini yokuzivikela yomuntu siqu | Kuyadingeka ngenxa yemvelo yokuzwela yama-isocyanates. |
Imiphumela Efakazelwe Kuzinhlelo Zokusebenza Zangempela
Uyabona izinzuzo zomsuka waseShayina I-Desmodur RE ezimbonini eziningi. Abenzi bezicathulo bayisebenzisela ukubopha izithende zerabha esikhumbeni noma endwangu. Abakhiqizi bezimoto bayisebenzisela ama-clearcoats ahlala ecwebezela futhi eqinile. Abakhi bayisebenzisela ukumboza okubonakala kusha iminyaka eminingi.
Uthola nobuchwepheshe bamuva. I-Desmodur RE evela eShayina isekela izinhlelo ezixubile ezixuba i-polyurethane ne-silicone ukuze kube nokumelana okungcono nesimo sezulu.
