Tshwj xeeb Iav Metering Pump Rau Isocyanates

Qhov no yog qhov siab -precision, zoo- hloov iav ntsuas twj tso kua mis tshwj xeeb tsim los rau kev lag luam polyurethane los tuav TDI, MDI, thiab hloov kho isocyanate media. Vim yog cov tshuaj lom neeg muaj zog ntawm isocyanates, kev sib cuag nrog cov dej noo tuaj yeem ua rau hydrolysis, crystallization, thiab nag lossis daus, ua rau muaj kev sib tsoo thiab metering drift. Cov

twj tso kua mis nta 316L stainless hlau wetted qhov chaw thiab tshwj xeeb FKM / FFKM seals. Cov kev xaiv muaj xws li xau-dawb sib nqus tsav tsim thiab lub tsho tiv thaiv thermal rwb thaiv tsev, ua rau nws tsim nyog rau polyurethane foaming, elastomer, thiab nplaum ntau lawm kab kom paub meej meej proportioning thiab xa ntawm isocyanates thiab polyether polyols.

Nta
1. Tsim los rau Isocyanate Daim Ntawv Thov: Wetted qhov chaw yog ua los ntawm cov cuab yeej hlau kom tshem tawm cov hlau ion paug; siv FKM / FFKM fluoroelastomer seals (tus qauv Nitrile lossis EPDM roj hmab yog txwv nruj heev); xaiv tau flushable foob tsim tiv thaiv kev sib tsoo los ntawm hydrolysis crystallization.
2. High-Precision Volumetric Metering: Flow rate yog nruj me ntsis linear nrog rotational ceev, muab ib tug metering repeatability ntawm ± 0.5%; Ua kom ruaj khov A / B tivthaiv qhov sib piv thiab tiv thaiv qhov tsis xws luag xws li shrinkage, tawg, thiab tsis sib npaug ntawm cov khoom ua npuas ncauj tiav; txhawb kev koom ua ke nrog kev siv tshuaj tsis siv neeg los ntawm servo lossis sib txawv -frequency drives (VFD).
3. Muaj kev nyab xeeb, Leak-Proof Design: Kev xaiv cov hlau nplaum sib txuas (tsis muaj qhov sib khi) tsim kom ntseeg tau tias xoom xau- zoo tagnrho rau cov tshuaj lom neeg, tsis muaj zog isocyanates- tshem tawm cov kev pheej hmoo ntawm kev tawm sab nraud; Tsis tas li ntawd, muaj ob lub tshuab foob kev teeb tsa nrog lub kaw lus dej thaiv.
4. Kev xaiv Thermal Jacket: Circulates tshav kub-hloov roj kom tswj tau qhov kub thiab txias, tiv thaiv MDI crystallization ntawm qhov kub thiab txias thiab ua kom cov kua dej ntws; haum rau kev tsim khoom tas li nyob rau lub caij ntuj no lossis qis - qhov chaw ua haujlwm kub.
5. Dav Viscosity Range: Tau tshaj isocyanate viscosities ntawm 50–10000 mPa·s; optimized bearing qauv ua kom ruaj khov nyob rau lub sijhawm ntev - lub sijhawm ua haujlwm tas mus li, txawm tias cov xov xwm tsis muaj tus kheej -lubricating zog.

Tau tshaj Media
MDI, TDI, hloov isocyanates, thiab polyurethane isocyanate Cheebtsam; kuj haum rau conveying polyether polyols thiab polyester polyols.

Daim ntawv thov kev lag luam
- Polyurethane foaming: Txias cia vaj huam sib luag, rwb thaiv tsev pipeline, thiab cov khoom siv hauv tsev foaming ntau lawm kab
- Tsis siv neeg sib faib rau PU elastomers, cov khoom siv casting, polyurethane adhesives, thiab sealants
- Cov ntaub ntawv tshuaj tshiab: Metered hloov ntawm ob -cov khoom siv raw khoom

FAQ

Q1: Dab tsi yog cov khoom siv rau isocyanate twj tso kua mis?

A: Wetted qhov chaw txais cov qauv hlau, cov cuab yeej hlau, FKM lossis FFKM foob. NBR / EPDM roj hmab tsis tuaj yeem siv rau kev pabcuam isocyanate.

Q2: Yuav ua li cas kom tsis txhob muaj isocyanate crystallization hauv lub twj tso kua mis?

A: Khaws qhov system qhuav nrog kev tiv thaiv nitrogen; nruab inlet lim; xaiv cua sov-jacket version rau MDI; xaiv tau flush seal qauv.
