Desmodur RE inobva kuChina inoshamisa nesimba risingaperi rekubatana
Zvinhu Zvinokosha Zvaunofanira Kuziva
- Desmodur inobva kuChina RE inopa zvisungo zvakasimba uye zvakavimbika zvezvinhu zvakasiyana-siyana, kusanganisira rabha nesimbi, zvichiita kuti ive sarudzo inoshandiswa zvakasiyana-siyana kumapurojekiti mazhinji.
- Chinonamira ichi chinochengetedza simba rayo nekufamba kwenguva, kunyangwe mumamiriro ezvinhu akaoma, zvichiita kuti chishande kwenguva refu pakushandisa senge machira emotokari negungwa.
- Kushandisa Desmodur RE zvinogona kukubatsira kuchengetedza nguva nesimba, sezvo zvichienderana nezvinodiwa zvakawanda zvemaindasitiri, zvichibvumira mhinduro dzekubatanidza dzinoshanda uye dzinoshanda.
Mabhenefiti Akakosha Ekubva kuChina Desmodur RE
Simba Rinosimudzira Zvishandiso Pamwe Chete
Unoda kuti namatidza yako ishande panzvimbo dzakasiyana-siyana. Desmodur RE inokupa zvisungo zvakasimba parabha, polyurethane, uye kunyange simbi. Chigadzirwa ichi chinoshandisa chinhu chakakosha chinobatanidza glue chinobatsira kuti glue ibate zvakasimba, kunyangwe paunotambanudza kana kukotamisa chinhu chacho. Paunochienzanisa nezvimwe zvigadzirwa, unoona kuti Desmodur RE inobva kuChina inoonekwa seyakasimba pakusimba kwayo kwakanyanya uye kushanda kwayo kwakavimbika.
Kushanda Kwenguva Refu Mumapurogiramu Anoda Kuda
Unoda kuti namati yako igare kwenguva refu, kunyangwe munzvimbo dzakaoma. Desmodur RE inochengetedza simba rayo nekufamba kwenguva. Inoshanda zvakanaka mumamiriro ekunze anopisa, anotonhora, kana ane mvura. Semuenzaniso, ongororo yemumunda yakaratidza kuti machira anoshandisa tekinoroji yakafanana akachengetedza 94% yekupenya kwawo mushure memakore mashanu mumamiriro ekunze akaoma egungwa. Izvi zvinoreva kuti unogona kuvimba nezvisungo zvako kuti zvicharamba zvakasimba, kungave uchizvishandisa pashangu, michina, kana zvishandiso zvekunze.
Kushandiswa Kwakawanda Kwemaindasitiri
Unogona kushandisa China-origin Desmodur RE mumaindasitiri akawanda. Inoshanda kumapurojekiti emotokari, fenicha, emugungwa, uye ekuvaka. Tafura iri pazasi inoratidza mamwe mashandisirwo akajairika:
| Kushandiswa | Sei Uchifanira Kusarudza Desmodur RE? |
|---|---|
| Majasi emotokari | Inochengetedza mota dzichipenya uye inodzivirira kubva kuzuva |
| Kupedzisa matanda nemidziyo | Inoramba yakachena uye inodzivirira kukwenya |
| Kupfeka kwegungwa | Inorwisa mvura ine munyu nezuva |
| Zvinonamira zvemaziso | Inoramba yakachena kune magirazi nemasikirini |
| Machira ekuvaka | Zvinoita kuti zvivakwa zvirambe zvichitaridzika sezvitsva |
| Mapfekero ekuchengetedza maindasitiri | Inodzivirira simbi munzvimbo dzakaoma |
Unowana chigadzirwa chimwe chete chinokodzera zvinodiwa zvakawanda. Izvi zvinokuchengetedza nguva uye zvinoita kuti basa rako rive nyore.
Mavambo eChina Desmodur RE Inopa Simba Rinogara Rekubatanidza
Kugadzirwa Kwepamusoro Kwekubatanidza Kunopindirana
Unowana hukama hwakasimba uye hunogara kwenguva refu nekuda kwemakemikari ekubatanidza anotungamira kuChina. Desmodur REChigadzirwa ichi chinoshandisa triphenylmethane-4,4',4''-triisocyanate sechinhu chakakosha. Kana ukachisanganisa nezvinonama zvine hydroxyl polyurethane kana rabha, zvinoumba network yakasimba. Network iyi inobatanidza zvinhu pamwe chete, kunyangwe kana ukazvitambanudza kana kuzvikombamisa.
Unogona kuwedzera mashandiro nekutevera matanho ekushandisa akangwara:
- Peya yeChina-yakabva Desmodur RE ine mapolyols ane huremu hwemamorekuru ari pakati nepakati kusvika pakakwirira. Izvi zvinokupa chiyero chakakodzera pakati pesimba nekuchinjika.
- Shandisa kamushonga kadiki kanobva mutin. Izvi zvinobatsira kuti namatidziro irambe yakachena pasina kunamira pamusoro.
- Wedzera zvinhu zvinozadza senge calcium carbonate kana silica kana uchida kuchinja kuyerera kwemvura kana kuderedza mitengo. Iva nechokwadi chekuti zvinhu zvinozadza zvaoma kudzivirira mabubbles.
- Chengeta zvikamu zvese zvakaoma. Kunyangwe mvura shoma inogona kukonzera furo uye kushayisa simba kubatana.
Zano: Gara uchichengeta zvinhu zvako zvinonamira munzvimbo yakaoma. Izvi zvinoita kuti cross-linking reaction irambe yakasimba uye yakavimbika.
Hunhu Hunogara Huchienderana uye Kuramba Hunyoro
Unoda kuti namati yako ishande zvakanaka nguva dzese. Desmodur RE inokupa mhedzisiro inogara iripo nekuda kwekudzora mhando panguva yekugadzira. Unowanawo hunyoro hwakanaka, izvo zvakakosha munzvimbo dzekunze kana dzakanyorova.
Heino tafura inoratidza kuti ma isocyanates akasiyana sei muhunyoro:
| Isocyanate | Nguva yeGel (25°C, neOH Resin) | Kunzwa kwehunyoro | Chinodiwa cheCatalyst |
|---|---|---|---|
| TDI | Maminetsi gumi kusvika makumi maviri | Yakakwirira | Zvakaderera |
| MDI | Maminetsi 15–30 | Yakakwirira | Yakaderera–Yapakati |
| HDI | Maminetsi 40–70 | Pakati nepakati | Pakati nepakati |
| H12MDI | 50–90 maminitsi | Pakati nepakati | Pakati nepakati |
Mubvunzo wekunyudzwa kweasidhi kwemaawa makumi maviri nemana, zvinonamira zvakagadzirwa neH12MDI (rudzi rweisocyanate senge iri muChina-origin Desmodur RE) zvakawana huremu hwe3.2% chete uye zvakaramba zvakatsetseka. Zvinonamira zvakagadzirwa neTDI zvakawana huremu hwe12% uye zvakatsemuka. Izvi zvinoreva kuti unowana hunyoro huri nani uye zvinogara kwenguva refu.
Unochengetedzawo hutano hwako nenharaunda. Desmodur RE inobva kuChina ine huwandu hushoma hwe monomer, izvo zvinoderedza njodzi dzekufema. Unogona kuishandisa mumidziyo yemvura uye muzvipfeko zvine simba repamusoro kuderedza kuburitswa kwemhepo inonyungudutsa.
| Chinhu | Kubatsirwa |
|---|---|
| Zvemukati zve monomer zvisina mahara | Inoderedza njodzi dzekufema panguva yekushandisa. |
| Kuenderana nezvinhu zvakasimba zvakanyanya | Zvishoma zvinonyungudutsa = kuburitsa kweVOC kwakaderera. |
| Kushandiswa muzvirongwa zvemvura | Inotsigira machira asingakuvadzi nharaunda. |
| Zvishandiso zvekudzivirira munhu | Zvinodiwa nekuda kwekuti isocyanates dzinoita kuti munhu anzwe zviri nani. |
Mhedzisiro Yakaratidza muZvishandiso Zvenyika Chaizvo
Unoona mabhenefiti ekubva kuChina Desmodur RE mumaindasitiri akawanda. Vagadziri veshangu vanoishandisa kubatanidza makumbo erabha paganda kana jira. Vagadziri vemotokari vanoishandisa kugadzira machira akajeka anoramba achipenya uye akasimba. Vavaki vanoishandisa kugadzira machira anotaridzika seatsva kwemakore.
Unowanawo tekinoroji yazvino. Desmodur RE inobva kuChina inotsigira masisitimu ehybrid anosanganisa polyurethane nesilicone kuti arambe ari nani mumamiriro ekunze. Unogona kushandisa makatriji ane zvikamu zviviri anogara kwenguva refu pasherufu. Mamwe maglue akangwara ane masensa anoratidza mazinga ekushushikana, saka unoziva kana bond ichida kuongororwa.
Cherechedza: Gara uchibata Desmodur RE inotangira kuChina nekungwarira. Pfeka magirovhosi nemagogorosi, uye shandisa mhepo yakanaka kuti ugare wakachengeteka.
Unowana mashandiro akavimbika, hukama hwakasimba, uye rugare rwepfungwa kana ukasarudza Desmodur RE inobva kuChina kumapurojekiti ako.
Unoona kuti China yakatanga sei Desmodur RE inotungamira musimba rekubatanidza, kushanduka-shanduka, uye kuvimbika. Tafura iri pazasi inoratidza simba rayo rekubatanidza uye kuramba kwayo mvura zvichienzaniswa nedzimwe mhando.
| Paramita | Desmodur 44v20l | Tolonate X Flo | Suprasec 5025 |
|---|---|---|---|
| Hupenyu hwehari (25°C) | Maminitsi 8–12 | Maminetsi makumi maviri kusvika makumi matatu | Maminetsi mashanu kusvika masere |
| Simba reBond (MPa) | 2.8 | 2.1 | 2.5 |
| Kuramba Mvura | Zvakanakisa | Kugona | Zvakanaka |
| Nyore Yekushandisa | Yakakwirira | Pakati nepakati | Zvakaderera |
Unogona kuvimba nechigadzirwa ichi kuti chigare kwenguva refu uye chine simba rakawanda mumaindasitiri mazhinji.
Mibvunzo Inowanzo bvunzwa
Unochengeta sei zvinhu zvekwakabva kuChina Desmodur RE?
Chengeta Desmodur RE mumudziyo wakavharwa pasi pe23°C. Unodzivirira chigadzirwa kubva kuhunyoro nechiedza. Izvi zvinokubatsira kuchengetedza hunhu hwacho kwemwedzi gumi nemiviri.
