    Incazelo

    I-MOFAN ML90 iyi-methylal emsulwa kakhulu enokuqukethwe okungaphezu kuka-99.5%, iyi-ejenti yokufutha engokwemvelo futhi engabizi kakhulu esebenza kahle kwezobuchwepheshe. Ihlanganiswe nama-polyol, ukusha kwayo kungalawulwa. Ingasetshenziswa njenge-ejenti yokufutha kuphela ekwakhiweni, kodwa futhi iletha izinzuzo ngokuhlanganiswa nazo zonke ezinye izinto zokufutha.

    Ubumsulwa Nokusebenza Okungalingani

    I-MOFAN ML90 ivelele emakethe ngenxa yobumsulwa bayo obungenakuqhathaniswa. Le methylal emsulwa kakhulu ayiwona nje umkhiqizo; iyisisombululo esenzelwe abakhiqizi ababeka phambili ikhwalithi kanye nokusimama. Ubumsulwa obuphezulu be-MOFAN ML90 buqinisekisa ukuthi ihlangabezana nezidingo eziqinile zezicelo ezahlukahlukene ze-foam, ihlinzeka ngemiphumela ehambisanayo futhi ithuthukisa ikhwalithi iyonke yomkhiqizo wokugcina.

    I-ejenti Yokuvunguza Kwemvelo Nezomnotho

    Njengoba izimboni zilwela ukunciphisa ukuthinteka kwazo kwemvelo, i-MOFAN ML90 ivela njengokukhetha okungokwemvelo nokonga. Ukwakheka kwayo kuvumela ukulawula okuphumelelayo kokusha uma kuhlanganiswa nama-polyol, okwenza kube inketho ephephile yezinhlelo zokusebenza eziningi. Lokhu kuguquguquka kusho ukuthi i-MOFAN ML90 ingasetshenziswa njenge-ejenti yokufutha kuphela ekwakhiweni noma ngokuhlanganiswa nezinye izinto zokufutha, okunikeza abakhiqizi ukuguquguquka abakudingayo ukuze bathuthukise izinqubo zabo.

    Izinzuzo

    ● Ayishisi kakhulu kune-n-Pentane kanye ne-Isopentane ezingashisi kakhulu. Izingxube ze-polyols ezinenani eliwusizo le-Methylal kuma-polyurethane foam zibonisa iphuzu eliphezulu lokukhanya.

    ● Inephrofayili enhle yobuthi bemvelo.

    ● I-GWP iyi-3/5 kuphela ye-GWP yamaPentanes.

    ● Ngeke i-hydrolyze ngonyaka ongu-1 ezingeni le-pH elingaphezu kwama-polyol angu-4 ahlanganisiwe.

    ● Ingaxutshwa ngokuphelele nawo wonke ama-polyol, kufaka phakathi ama-polyol e-aromatic polyester.

    ● Kuyisinciphisi esinamandla se-viscosity. Ukunciphisa kuncike ekuncipheni kwe-polyol ngokwayo: lapho iphakemei-viscosity, kulapho kuncipha khona.

    ● Ukusebenza kahle kokwenza igwebu kwe-1 wt eyengeziwe kufana ne-1.7~1.9wt HCFC-141B.

    Imibuzo Evame Ukubuzwa

    Ngikhiqiza i-polyurethane foam yesikhumba ehlanganisiwe yezingxenye zezimoto (amasondo okuqondisa, izindawo zokubeka izingalo). Ingabe i-MOFAN ML90 ingasetshenziswa njenge-ejenti yokufutha kuphela?

    Yebo, i-ML90 (i-high-methylal) ingasetshenziswa njenge-ejenti yokufutha kuphela, enikeza ukuqeda okuhle kwendawo kanye nesakhiwo samaseli esifanayo esinobukhulu obuphansi.

    Ifomula yami eqinile ye-foam isebenzisa i-HCFC-141b ekhishwa kancane kancane. Ingabe i-ML90 ingayithatha indawo yayo?

    Yebo, i-ML90 iyindlela ehlukile yemvelo neyongayo. Izinga layo lokubila (~42°C) kanye nokusebenza kahle kokuvuthela kuyafana, kudinga ukulungiswa okuncane kokwakheka.

    Ingakanani isilinganiso esivamile se-ML90 ku-foam eguquguqukayo yefenisha?

    Ama-phr angu-2–8 kuye ngokuthi ingakanani i-target density; amazinga aphezulu anciphisa ukuminyana kodwa angandisa ukuthamba kwe-foam. Hlanganisa namanzi ukuze uthole ithuba elihle lokuvula iseli.

    Ingabe i-ML90 ingaxutshwa nezinye izinto ezivuthelayo (isb., amanzi, i-cyclopentane, i-HFC 245fa)?

    Yebo, isebenza ngokubambisana nazo zonke izinto ezivamile zokufutha, ithuthukisa ukuncibilika kuma-polyol futhi inciphise inani lezinto ezifutha ndawonye ezidingekayo.

    I-foam yami eqinile kancane yokupakisha ayinazo izilinganiso eziqinile uma isetshenziswa ngamanzi kuphela. Ingasiza kanjani i-ML90?

    Ukwengeza i-3–5 phr ML90 kunciphisa izinga lamanzi elidingekayo, kwehlisa i-exotherm yangaphakathi futhi kuthuthukise ukuzinza kobukhulu.

    Ingabe i-MOFAN ML90 iyavutha? Ungayisingatha kanjani ngokuphephile esitshalweni se-foam?

    Yebo, i-methylal iyasha. Sebenzisa imishini efanele yokungenisa umoya, yokumisa phansi, kanye neyokuvikela ukuqhuma; ingaxutshwa ngokuphephile nama-polyol ukuze kuncishiswe ukusha.

    Ifomu lami eliqinile lokufutha linobuso obuqinile ngenxa yokuhwamuka okusheshayo kwento evuthelayo. Ingabe i-ML90 izoyithuthukisa?

    Iphuzu layo lokubila eliphakathi nendawo kanye nokuncibilika okuhle kuma-polyol kunciphisa ukunwebeka kwangaphambi kokukhula, okunikeza indawo ebushelelezi.

    Iyini inzuzo ye-ML90 kune-acetone noma ezinye izinto ezivuthelayo ezibonakalayo ku-foam eguquguqukayo?

    I-ML90 inephunga eliphansi, ukuncibilika okungcono, futhi inikeza amaseli amancane; futhi ayibangeli ukushintsha kombala kwe-foam.

    Ingabe i-ML90 ingasetshenziswa kuma-elastomer e-polyurethane ukunciphisa ubuningi?

    Yebo, kuma-elastomer amancane (isb., amathe ezicathulo), sebenzisa i-1–3 phr ML90 kanye namanzi; kusiza ekunciphiseni ubuningi ngaphandle kwamaseli amakhulu.

    Kuyini ubumsulwa be-MOFAN ML90 futhi buthinta kanjani ikhwalithi ye-foam?

    Ubumsulwa obungu-≥99.5% buqinisekisa ukusebenza okulinganayo, ukusabela okuncane okuseceleni, kanye nephunga eliphansi elisele ku-foam eqediwe.
