Lub pouring taub hau txoj hauj lwm tswj mechanism ntawm lubhigh-pressure foaming tshuabsuav nrog lub taub hau thiab lub tes tsho teem sab nraum lub taub hau.Ib ntsug hydraulic lub tog raj kheej yog teem nruab nrab ntawm lub tes tsho thiab lub taub hau pouring.Lub tog raj kheej lub cev ntawm ntsug hydraulic lub tog raj kheej txuas nrog lub tes tsho.Lub valve Lub pas nrig txuas nrog lub taub hau pouring.Nyob rau tib lub sijhawm, muaj kab rov tav qhia kev tsheb ciav hlau ntawm lub tshuab cement foaming lub cev, thiab ib qho kev qhia qhov qhov sib piv rau cov lus qhia kev tsheb ciav hlau tau muab rau ntawm lub tes tsho.Kab rov tav hydraulic lub tog raj kheej yog muab nruab nrab ntawm lub siab-siab foaming tshuab lub cev thiab lub tes tsho.Lub tog raj kheej lub tog raj kheej ntawm kab rov tav hydraulic lub tog raj kheej txuas nrog lub cev ntawm lub tshuab ua haujlwm siab, thiab lub valve qia txuas nrog lub tes tsho.Cov qauv siv hluav taws xob muaj qhov zoo ntawm kev ua haujlwm txuag thiab kev ua haujlwm siab.

Ob lub ntsiab lus A thiab Bpolyurethane foaming tshuabyog cov proportioned precisely thiab stirred ntawm ib tug ceev ceev, thiab ob lub Cheebtsam A thiab B raug xa mus rau lub mixing taub hau los ntawm ob high-precision metering twj tso kua mis.Tom qab kev kub ceev thiab muaj zog nplawm, cov khoom ua kua yog sib npaug sib npaug los ua cov khoom xav tau.

Lub tshuab ua tiav high-pressure foaming muaj cov hauv qab no: cov khoom siv ntws, ntsuas qhov system, cua Circuit Court system, cua sov system, tu system, tshwj xeeb cov cuab yeej rau polyurethane ua npuas ncauj infusion thiab foaming.Ntev npaum li cov khoom siv polyurethane raw khoom (isocyanate thiab polyether polyol Cheebtsam) ua tau raws li qhov ntsuas kev ua tau zoo ntawm kev tsim.Nws yog tsim los ntawm polyether polyol thiab polyisocyanate nyob rau hauv lub xub ntiag ntawm foaming agents, catalysts, emulsifiers thiab lwm yam chemical additives, tom qab tshuaj tiv thaiv foaming thiab ua npuas ncauj.Muaj peb hom txheej txheem ua npuas dej hauv lub tshuab ua npuas siab: ua ntej-polymer txoj kev, ib nrab-polymer txoj kev thiab ib-kauj ruam foaming pre-polymer txheej txheem foaming txheej txheem yog ua ntej-polymer (cov khoom dawb) thiab (cov khoom siv dub) ua ntej, thiab tom qab ntawd ntxiv dej, catalyst, surfactant, thiab lwm yam additives nyob rau hauv lub pre-polymer tov nyob rau hauv high-speed stirring rau foaming, tom qab kho ntawm ib tug tej yam kub yuav matured.Cov txheej txheem foaming ntawm cov txheej txheem semi-prepolymer yog ua ib feem ntawm polyether polyol (cov khoom siv dawb) thiab diisocyanate (cov khoom siv dub) rau hauv prepolymer ua ntej, tom qab ntawd ntxiv lwm qhov ntawm polyether lossis polyester polyol thiab diisocyanate, dej, catalyst, surfactant. , lwm yam additives, thiab lwm yam, thiab sib tov nyob rau hauv kev kub ceev stirring rau foaming.Cov polyether lossis polyester polyol (dawb) thiab polyisocyanate (dub), dej, catalyst, surfactant, tshuab tshuab, lwm yam additives, thiab lwm yam yog ntxiv rau hauv ib kauj ruam thiab sib tov ntawm kev kub ceev rau foaming.Cov txheej txheem ib-kauj ruam foaming yog cov txheej txheem feem ntau siv niaj hnub no.Kuj tseem muaj cov txheej txheem foaming phau ntawv, uas yog txoj kev yooj yim tshaj plaws, qhov twg tag nrho cov khoom siv raw tau raug ntsuas kom raug, muab tso rau hauv ib lub thawv thiab tom qab ntawd tam sim ntawd sib tov thiab txhaj rau hauv pwm lossis qhov chaw kom ntim nrog npuas.Lus Cim: Cov polyisocyanate (dub) yuav tsum tau ntsuas qhov kawg.

Covpolyurethane ua npuas ncauj tshuabe feem ntau foams ntawm chav tsev kub, thiab cov txheej txheem molding yog qhov yooj yim.Raws li qib ntawm kev tsim kho tshuab, nws tuaj yeem muab faib ua phau ntawv foaming thiab tshuab foaming;raws li lub siab ntawm foaming, nws tuaj yeem muab faib ua qhov tsis tshua muaj siab foaming thiab low-pressure foaming;Raws li txoj kev molding, nws tuaj yeem muab faib ua cov foaming thiab txau foaming.
