Desmodur RE yochokera ku China imadabwitsa ndi mphamvu yokhazikika yolumikizirana
Mfundo Zofunika Kwambiri
- Desmodur wochokera ku China RE imapereka maubwenzi olimba komanso odalirika pazinthu zosiyanasiyana, kuphatikizapo rabara ndi chitsulo, zomwe zimapangitsa kuti ikhale chisankho chosinthasintha pamapulojekiti ambiri.
- Guluu uyu amasunga mphamvu zake pakapita nthawi, ngakhale m'mikhalidwe yovuta, zomwe zimapangitsa kuti ntchito yake ikhale yogwira ntchito kwa nthawi yayitali monga zophimba zamagalimoto ndi zam'madzi.
- Kugwiritsa ntchito Desmodur RE Zingakupulumutseni nthawi ndi khama, chifukwa zimagwirizana ndi zosowa zambiri zamafakitale, zomwe zimathandiza kuti pakhale njira zolumikizirana zogwira mtima komanso zothandiza.
Ubwino Waukulu wa Chitchaina Desmodur RE
Mphamvu Yapamwamba Yogwirizanitsa Zinthu Zonse
Mukufuna kuti guluu wanu ugwire ntchito pamalo osiyanasiyana. Desmodur RE imakupatsani zomangira zolimba pa rabara, polyurethane, komanso chitsulo. Chogulitsachi chimagwiritsa ntchito cholumikizira chapadera chomwe chimathandiza guluu kugwira bwino, ngakhale mutatambasula kapena kupinda nsaluyo. Mukachiyerekeza ndi zinthu zina, mumawona kuti Desmodur RE yochokera ku China imadziwika ndi mphamvu zake zokoka komanso magwiridwe antchito odalirika.
Kugwira Ntchito Kokhalitsa mu Ntchito Zovuta
Mufunika guluu wanu kuti ukhale wolimba, ngakhale m'malo ovuta. Desmodur RE Imasunga mphamvu zake pakapita nthawi. Imagwira ntchito bwino m'malo otentha, ozizira, kapena onyowa. Mwachitsanzo, kafukufuku wa m'munda adawonetsa kuti zophimba pogwiritsa ntchito ukadaulo wofanana zimasunga 94% ya kuwala kwawo patatha zaka zisanu m'nyengo yozizira kwambiri ya m'mphepete mwa nyanja. Izi zikutanthauza kuti mutha kudalira zomangira zanu kuti zikhale zolimba, kaya mukuzigwiritsa ntchito pa nsapato, makina, kapena zida zakunja.
Kusinthasintha kwa Ntchito Zambiri Zamafakitale
Mutha kugwiritsa ntchito chida chochokera ku China Desmodur RE m'mafakitale ambiri. Imagwira ntchito zamagalimoto, mipando, zapamadzi, ndi zomangamanga. Tebulo ili pansipa likuwonetsa ntchito zina zomwe zimafala:
| Kugwiritsa ntchito | Chifukwa Chosankha Desmodur RE? |
|---|---|
| Zovala zoyera zamagalimoto | Zimateteza magalimoto ku kuwala komanso kuteteza ku dzuwa |
| Zomaliza zamatabwa ndi mipando | Imakhalabe yoyera ndipo imakana kukanda |
| Zophimba zam'madzi | Amalimbana ndi madzi amchere ndi dzuwa |
| Zomatira zowala | Zimakhalabe zoyera pa magalasi ndi zowonetsera |
| Zophimba zomangamanga | Zimathandiza kuti nyumba zizioneka zatsopano |
| Zophimba zosamalira mafakitale | Amateteza chitsulo m'malo ovuta |
Mumapeza chinthu chimodzi chomwe chikugwirizana ndi zosowa zambiri. Izi zimakupulumutsirani nthawi komanso zimapangitsa ntchito yanu kukhala yosavuta.
Kodi China inachokera kuti? Desmodur RE Amapereka Mphamvu Yokhalitsa Yogwirizanitsa
Kupanga Kogwirizana Kwambiri
Mumapeza maubwenzi olimba komanso okhalitsa chifukwa cha chemistry yolumikizana bwino kwambiri yomwe imachokera ku China. Desmodur RE. Chogulitsachi chimagwiritsa ntchito triphenylmethane-4,4',4''-triisocyanate ngati chinthu chofunikira kwambiri. Mukachisakaniza ndi zomatira zomwe zili ndi hydroxyl polyurethane kapena rabara, chimapanga netiweki yolimba. Netiweki iyi imagwirizanitsa zinthu pamodzi, ngakhale mutazitambasula kapena kuzipinda.
Mukhoza kukulitsa magwiridwe antchito mwa kutsatira njira zanzeru zogwiritsira ntchito:
- Awiri ochokera ku China Desmodur RE ndi ma polyol olemera pakati mpaka apamwamba. Izi zimakupatsani mgwirizano woyenera pakati pa mphamvu ndi kusinthasintha.
- Gwiritsani ntchito chothandizira chochepa chopangidwa ndi chitini. Izi zimathandiza kuti guluu ukhale wolimba popanda kupangitsa pamwamba pake kukhala pamati.
- Onjezani zinthu zodzaza monga calcium carbonate kapena silica ngati mukufuna kusintha kayendedwe ka madzi kapena kuchepetsa ndalama. Onetsetsani kuti zinthu zodzazazo ndi zouma kuti mupewe thovu.
- Sungani mbali zonse zouma. Ngakhale madzi pang'ono angayambitse thovu ndikufooketsa mgwirizano.
Langizo: Nthawi zonse sungani zinthu zanu zomatira pamalo ouma. Izi zimapangitsa kuti cross-linking reaction ikhale yolimba komanso yodalirika.
Ubwino Wokhazikika ndi Kukana Chinyezi
Mukufuna kuti guluu wanu ugwire ntchito bwino nthawi zonse. Desmodur RE Zimakupatsani zotsatira zokhazikika chifukwa cha kuwongolera bwino khalidwe panthawi yopanga. Mumapezanso kukana chinyezi kwambiri, komwe ndikofunikira kwambiri panja kapena pamalo onyowa.
Nayi tebulo lomwe likuwonetsa momwe ma isocyanates osiyanasiyana amafananira ndi kukhudzidwa ndi chinyezi:
| Isocyanate | Nthawi ya Gel (25°C, yokhala ndi OH Resin) | Kuzindikira chinyezi | Chothandizira Chofunikira |
|---|---|---|---|
| TDI | Mphindi 10–20 | Pamwamba | Zochepa |
| MDI | Mphindi 15–30 | Pamwamba | Wotsika–Wapakati |
| HDI | Mphindi 40–70 | Pakatikati | Pakatikati |
| H12MDI | Mphindi 50–90 | Pakatikati | Pakatikati |
Mu mayeso oyesa kumiza asidi kwa maola 24, zomatira zopangidwa ndi H12MDI (mtundu wa isocyanate ngati womwe uli ku China-origin Desmodur RE) zinalemera ndi 3.2% yokha ndipo zinakhalabe zosalala. Zomatira zochokera ku TDI zinalemera ndi 12% ndipo zinasweka. Izi zikutanthauza kuti mumakhala ndi kukana chinyezi bwino komanso zomangira zokhalitsa.
Mumatetezanso thanzi lanu komanso chilengedwe. Desmodur RE yochokera ku China ili ndi monomer yochepa, yomwe imachepetsa chiopsezo chopuma. Mutha kuigwiritsa ntchito m'makina oyendera madzi ndi zokutira zolimba kuti muchepetse kutulutsa mpweya woipa.
| Mbali | Phindu |
|---|---|
| Zinthu zochepa zaulere za monomer | Amachepetsa chiopsezo chopuma panthawi yogwiritsa ntchito. |
| Kugwirizana ndi zinthu zolimba kwambiri | Zosungunulira zochepa = mpweya wochepa wa VOC. |
| Kugwiritsa ntchito m'machitidwe oyendera madzi | Imathandizira zophimba zachilengedwe. |
| Zipangizo zodzitetezera | Izi ndizofunikira chifukwa chakuti isocyanates imapangitsa kuti thupi likhale lolimba. |
Zotsatira Zotsimikizika mu Mapulogalamu Apadziko Lonse
Mukuona ubwino wa dziko la China Desmodur RE m'mafakitale ambiri. Opanga nsapato amagwiritsa ntchito izi pomangirira zidendene za rabara ku chikopa kapena nsalu. Opanga magalimoto amagwiritsa ntchito izi popanga ma clearcoats omwe amakhalabe owala komanso olimba. Omanga amagwiritsa ntchito izi popanga ma claddings omwe amawoneka atsopano kwa zaka zambiri.
Mumapezanso ukadaulo waposachedwa. Desmodur RE yochokera ku China imathandizira makina osakanikirana omwe amasakaniza polyurethane ndi silicone kuti azitha kupirira nyengo bwino. Mutha kugwiritsa ntchito makatiriji azinthu ziwiri omwe amakhala nthawi yayitali pashelefu. Magulu ena anzeru amakhala ndi masensa omwe amawonetsa kuchuluka kwa kupsinjika, kotero mumadziwa nthawi yomwe bond ikufunika kuyang'aniridwa.
Zindikirani: Nthawi zonse gwiritsani ntchito Desmodur RE yochokera ku China mosamala. Valani magolovesi ndi magalasi, ndipo gwiritsani ntchito mpweya wabwino kuti mukhale otetezeka.
Mumapeza magwiridwe antchito odalirika, maubwenzi olimba, komanso mtendere wamumtima mukasankha Desmodur RE yochokera ku China pa ntchito zanu.
Mukuona momwe China idayambira Desmodur RE Imatsogolera pa mphamvu ya ma bonding, kusinthasintha, komanso kudalirika. Gome ili pansipa likuwonetsa mphamvu yake yayikulu ya ma bonding komanso kukana madzi poyerekeza ndi mitundu ina.
| Chizindikiro | Desmodur 44v20l | Tolonate X Flo | Suprasec 5025 |
|---|---|---|---|
| Moyo wa Mphika (25°C) | Mphindi 8–12 | Mphindi 20–30 | Mphindi 5–8 |
| Mphamvu ya Bond (MPa) | 2.8 | 2.1 | 2.5 |
| Kukana Madzi | Zabwino kwambiri | Zabwino | Zabwino |
| Kusavuta Kugwiritsa Ntchito | Pamwamba | Pakatikati | Zochepa |
Mukhoza kukhulupirira izi kuti zikhale ndi ma bond olimba komanso okhalitsa m'mafakitale ambiri.
