Wopanga waku China mtengo wabwino Womatira RFE / DESMODUR RFE CAS 4151-51-3 Tris(4-isocyanatophenyl) thiophosphate
RFE yomatira yogwira ntchito bwino imatha kusintha DESMODURE RFE
Dzina la Mankhwala: Tris(4-isocyanatophenyl) thiophosphate
Dzina la Malonda: Adhesive RFE, Desmodur RFE
Nambala ya CAS 4151-51-3
Fomula ya molekyulu: C21H12N3O6PS
Chigawo:
Tris(4-isocyanatophenyl) thiophosphate / CAS No. 4151-51-3: 27%
Ethyl acetate / CAS Nambala 141-78-6: 72.5%

RFE yathu, ndi cholimba cha thiophosphoric-tris-(p-isocyanato-phenyl ester) mu ethyl acetate, nambala ya CAS 4151-51-3. Mtundu wowala ndi wothandizira kuchiritsa chilengedwe / crosslinker (mtundu wa isocyanate) womwe umagwiritsidwa ntchito kwambiri pa zomatira za rabara yachilengedwe ndi/kapena yopangidwa, makamaka pazipangizo za rabara. Ubwino wake ndi mtundu wake wopepuka mpaka wopanda mtundu komanso wokana chikasu, RFE ndi yankho labwino kwambiri lofuna mtundu kwambiri, loyenera bwino zomatira za cr zolumikizidwa, zomatira za rabara za chloroprene ndi zomatira za hydroxyl polyurethane. RFE imathanso kukonza mgwirizano wa pulasitiki wa PVC, mafuta a SBR, chikopa chapamwamba/primer, silika ndi zina zotero. RFE ikhozanso kuwonjezeredwa mu mankhwala ochizira khungu la mafuta kuti ikhale yolimba komanso yokana mafuta. Chosungunulira cha RFE ndi ethyl acetate (EAC), chomwe chikugwirizana ndi malamulo oteteza chilengedwe poyerekeza ndi methylene chloride. Kuwonjezera RFE mu zomatira, kumayambitsa crosslinking reaction ndi substrates zolumikizira, makamaka pazipangizo za rabara.
Guluu wa zigawo ziwiri uyenera kugwiritsidwa ntchito mkati mwa nthawi yoyenera mutayika mutayika RFE. Kutalika kwa nthawi yoyenera sikungokhudzana ndi kuchuluka kwa polima mu guluu, komanso zigawo zina zofunika (Monga reisn, antioxygen, plasticizer, solvent, ndi zina zotero. Ikakhala pafupi ndi nthawi yoyenera, nthawi zambiri maola ochepa kapena tsiku limodzi logwira ntchito, guluu umakhala wovuta kugwiritsa ntchito, ndipo kukhuthala kumawonjezeka posachedwa, Pomaliza, umakhala jelly wosasinthika.
RFE ingagwiritsidwe ntchito ngati guluu wa rabara ndi chitsulo, komanso ngati cholumikizira chophikira cha zomatira za mphira ndi zomatira za polyurethane zopangidwa ndi solvent.
Kuchuluka kwake nthawi zambiri kumakhala pakati pa 4% mpaka 7% ya zomatira zopangidwa ndi zosungunulira zomwe zatchulidwa pamwambapa. Zimagwiritsidwa ntchito makamaka pazinthu zopanda utoto kapena zowala.
Kugwiritsa ntchito kuphatikiza:
- Kugwirizana kwa mphira wovunda (kapena wosavunda) ndi PVC, PU, SBS ndi ma polima ena ogwirizana ndi zinthu ndi zitsulo (chitsulo/aluminiyamu).
- Monga chothandizira kuchiritsa ma glue a neoprene kuti awonjezere mphamvu ya ma bonding; chothandizira kuchiritsa ma bonding a rabara ndi nsalu.
- Monga cholumikizira cholumikizira cha zigawo za hydroxyl za zinthu za polyurethane (elastomers, zokutira, ndi zina zotero).
- Monga cholumikizira cholumikizira cha zomatira za polyurethane zochotsedwa ndi hydroxyl zomwe zimagwiritsidwa ntchito mumakampani opanga nsapato, zomwe zimatha kukulitsa mphamvu yoyambira yomatira, kukana kutentha ndi zizindikiro zina.
- Amayikidwa kwambiri pa nsapato, masutukesi, matumba kuti amangirire nsalu ndi PVC ndi/kapena PU.
Mlingo woyenera:
Kutengera njira yolumikizirana ndi magawo, mlingo woyenera kwambiri umalimbikitsidwa pamitundu yosiyanasiyana.
Pa zomatira zotsukira za magawo 100 polemera (pbw) kutengera:
Rabala ya Graft-Chloroprene (yomwe ili ndi rabala pafupifupi 16%): 3%-5% pbw RFE
Rabala ya chloroprene (yomwe ili ndi rabala pafupifupi 20%): 5%-7% pbw RFE
Hydroxyl polyurethane (kuchuluka kwa polyurethane pafupifupi 15%): 3%-5% pbw RFE
Kugwirizana ndi zosungunulira:
RFE yathu imatha kuchepetsedwa ndi anhydrous ndi alcohol-free ethyl acetate dichloropropane, trichloroethylene, acetone, methyl ethyl ketone, toluene ndi zosungunulira zina. Kuwonjezera kuchuluka kwakukulu kwa aliphatic hydrocarbons kungayambitse matope. Komabe, yankho la aliphatic hydrocarbons mu rabara yachilengedwe (NR) limasonyeza kuti limagwirizana bwino ndi RFE. Chifukwa chake, palibe chifukwa chowonjezera zosungunulira zina.
Kulongedza:
Mtundu 1. 750g/botolo, mabotolo 20 mu katoni imodzi, makatoni 24 kapena 30 mu phaleti imodzi;
Mtundu wachiwiri. 20kg/ng'oma, ng'oma 18 kapena ng'oma 27 mu mphasa imodzi;
Mtundu wa 3. 55kg/ng'oma, ng'oma 8 kapena 12 mu mphasa imodzi;
Mtundu wachinayi. 180kg/ng'oma, ng'oma zinayi mu mphasa imodzi
Malo Osungirako:
Chonde sungani mu chidebe chosindikizidwa choyambirira cha 5℃-32℃, zinthuzo zitha kusungidwa bwino kwa miyezi 12.
Zinthu zathu zonse zotsatizana zimakhala zovuta kwambiri ku chinyezi; Zimapanga carbon dioxide ndi urea yosasungunuka mu madzi. Ngati zipezeka mumlengalenga kapena/ndi kuwala, zidzapangitsa kuti mitundu ya zinthu izi isinthe mwachangu.
(Koma ntchito yothandiza idzakhudzidwa ndi bot.)
Chitetezo:
Chilengedwe choopsa, chotupa kwambiri, chimakhudza maso, ngati chapumidwa chingayambitse ziwengo. Kukhudza pafupipafupi kungayambitse khungu louma kapena kutopa. Nthunzi ya zinthu zomwe zimadyedwa imatha kupangitsa munthu kutopa komanso kumva chizungulire.
