umkhiqizo

Yesigcilikisha RFE / DESMODUR RFE CAS 4151-51-3

Incazelo emfushane:

Okunamathiselwe okubili kufanele kusetshenziswe esikhathini esifanele ngemuva kokufaka ngemuva kokufaka i-RFE. Ubude besikhathi esisebenzayo abuhlobene kuphela nokuqukethwe kwe-polymer, kodwa futhi nezinye izinto ezifanele (Njenge-reisn, antioxygen, plasticizer, solvent, njll. Lapho ususondele esikhathini esifanele, imvamisa amahora ambalwa noma usuku olulodwa lokusebenza, ingcina kuba nzima ukusebenza, futhi i-viscosity ikhuphuka maduze, Ekugcineni, iba i-jelly engalungiseki. I-100 quality adhesive, Hydroxyl polyurethane (Polyurethane account for 20%), RFE dose 4-7. Chloroprene rubber (Rubber account for 20%) , Umthamo wethu we-RFE 4-7.


Imininingwane yomkhiqizo

Amathegi womkhiqizo

Incazelo Yomkhiqizo

Ukunamathela okuphezulu okusebenzayo kwe-Isocyanate RFE kungashintsha i-DESMODURE RFE

Izici zomkhiqizo

I-RFE polyisocyanate iyi-crosslinker esebenza kahle kakhulu yokunamathela okususelwa ku-polyurethane, iraba lemvelo nenjoloba yokwenziwa, iyasiza futhi ekwenzeni ngcono ukunamathela kwezinto ezisuselwa enjoloba. Ingasetshenziswa njenge-crosslinker.

Imininingwane yomkhiqizo

Umkhiqizo wezimpahla zomkhiqizo: RFE, RF

Ifomula yomkhiqizo: C21H12N3O6SP

I-sub sub volume: 465

Iphuzu lokuncibilika: 84-86 ℃

Ukubukeka

Uketshezi olunombala ophuzi onsundu. Umbala wayo awuthinti amandla okubopha.

Imikhiqizo ingaqukatha inzika ye-lamellar.

Isicelo somkhiqizo

Okunamathiselwe okubili kufanele kusetshenziswe esikhathini esifanele ngemuva kokufaka ngemuva kokufaka i-RFE. Ubude besikhathi esisebenzayo abuhlobene kuphela nokuqukethwe kwe-polymer, kodwa futhi nezinye izinto ezifanele (Njenge-reisn, antioxygen, plasticizer, solvent, njll. Lapho ususondele esikhathini esifanele, imvamisa amahora ambalwa noma usuku olulodwa lokusebenza, ingcina kuba nzima ukusebenza, futhi i-viscosity ikhuphuka maduze, Ekugcineni, iba i-jelly engalungiseki. I-100 quality adhesive, Hydroxyl polyurethane (Polyurethane account for 20%), RFE dose 4-7. Chloroprene rubber (Rubber account for 20%) , Umthamo wethu we-RFE 4-7.

Ezinye Izincazelo Ezihlobene

Ukupakisha:

I-750g / ibhodlela, amabhodlela angama-20 kwikhathoni elilodwa, amabhokisi angama-24 noma ama-30 ku-pallet eyodwa;

20kg / isigubhu, izigubhu eziyi-18 noma izigubhu ezingama-27 ku-pallet eyodwa;

55kg / isigubhu, 8 noma 12 izigubhu ku-pallet eyodwa;

180kg / isigubhu, izigubhu ezi-4 ku-pallet eyodwa

Isitoreji:

Sicela ugcinwe embizeni yokuqala evaliwe ngaphansi kwama-23 ℃, imikhiqizo ingagcinwa izinze ngamabhu ayisithupha.

Yonke imikhiqizo yethu yochungechunge izwela kakhulu kumswakama; Izokhiqiza i-carbon dioxide kanye ne-urea engancibiliki ekuphenduleni ngamanzi. Uma ukuvezwa emoyeni noma / nokukhanya, kuzosheshisa ukushintshwa kombala kwemikhiqizo.

Kepha umsebenzi osebenzayo uzothinteka.)

Ukuphepha:

Imvelo eyingozi, evuthayo kalula, ivuselela amehlo, uma ihogelwe ingadala ukungezwani komzimba. Ukuthintwa njalo kungaholela ekutheni isikhumba some noma sihlanye. Umusi wemikhiqizo ungenza umuntu akhathale ne-vertigo.
