    Ukuphatha nokugcina

    Izinyathelo Zokuqapha Ukuphatha Ngokuphephile: Izinyathelo Zobuchwepheshe/Izinyathelo Zokuqapha
    Izinyathelo zokuqapha zokugcina nokuphatha ezisebenza emikhiqizweni: Uketshezi. Ubuthi. Ukugqwala. Kuyavutha. Kuyingozi emvelweni. Nikezaumoya ofanele wokukhipha umoya emishinini.

    Iseluleko sokuphatha ngokuphephile
    Ukubhema, ukudla nokuphuza kufanele kuvinjelwe endaweni esetshenziswayo. Thatha izinyathelo zokuqapha ekukhipheni uketshezi olungasebenzi. Kuvuliwe.shaya idrama ngokucophelela ngoba okuqukethwe kungase kube ngaphansi kwengcindezi. Beka ingubo yomlilo eduze. Beka amashawa, izindawo zokugeza amehlo. Beka amanzi eduzeindawo yokusebenzisa. Ungasebenzisi umoya ukudlulisa. Vimbela yonke imithombo yezinhlansi kanye nokushisa - Ungabhemi. Sebenzisa kuphela endaweni equkethe ukuqhumaimishini yokufaka ubufakazi.

    Izindlela zokuhlanzeka
    Vimbela ukuthintana nesikhumba namehlo kanye nokuhogela umusi. Uma usebenzisa ungadli, ungaphuzi noma ungabhemi.
    Geza izandla ngemva kokuphatha. Susa izingubo ezingcolile kanye nemishini yokuzivikela ngaphambi kokungena ezindaweni zokudlela.

    Imibandela yokugcina ephephile, okuhlanganisa noma yikuphi ukungahambisani:
    Gcina endaweni eyomile, epholile futhi enomoya omuhle. Izitsha ezivulwa kumele zivalwe kabusha ngokucophelela futhi zigcinwe ziqonde phezulu ukuze kuvinjelwe ukuvuza.
    Gcina uvikelekile emswakama nasekushiseni. Susa yonke imithombo yokushisa. Faka ithangi lokubamba endaweni ehlanganisiwe. Faka phansi engangeni amanzi.
    Nikeza imishini kagesi engangeni manzi. Nikeza imishini kagesi kanye nemishini kagesi esetshenziswa ezindaweni eziqhumayo.
    Ungagcini ngaphezu kwalokhu: 50 °C

    Imikhiqizo engahambisani:
    Ama-oxidizing agents anamandla, ama-Perchlorate, ama-Nitrate, ama-Peroxide, ama-Acid anamandla, Amanzi, ama-Halogens, Umkhiqizo ongase usabele ngobudlova kuma-alkalineimvelo, ama-Nitrite, i-Nitrous acid - ama-Nitrite - i-oxygen.

    Imibuzo Evame Ukubuzwa

    Isembozo sami se-polyurethane sinamehlo enhlanzi ngenxa yokuxubana okungafanele. Ingabe i-TMPDA ingathuthukisa ukuhambisana?

    I-TMPDA inokuncibilika okuhle kokubili kuma-polyol kanye nama-isocyanates, okunciphisa ukuhlukaniswa kwesigaba kanye nokukhubazeka kwe-fish-eye.

    Iyini inzuzo ye-TMPDA kune-TMEDA ku-foam eqinile?

    I-TMPDA inokuguquguquka okuphansi futhi inikeza isilinganiso sejeli/sokuqhuma esilinganiselayo, okuholela kumaseli amancane ku-foam eqinile.

    Ngifuna ukwandisa impilo yebhodwe le-epoxy adhesive ngaphandle kokulahlekelwa ubulukhuni bokugcina. Kanjani?

    Sebenzisa i-TMPDA (1–3 phr) njenge-accelerator ecashile; inikeza ukuqala okuhamba kancane kodwa okuphelele ekushiseni kwegumbi.

    Ingabe i-TMPDA ingasetshenziswa ekusakazweni kwe-polyurethane etholakala emanzini?

    Yebo, ingafakwa ngemuva kokusatshalaliswa ukuze kulungiswe isivinini sokwakheka kwefilimu, kodwa qala ngokuhlola ukuzinza.

    I-PU elastomer yami inokuqina kobuso. Ngingaxazulula kanjani?

    Khulisa i-TMPDA ngo-0.1–0.2 phr ukuze kukhuthazwe ukwelashwa okuphelele kwendawo.

    Ingabe i-TMPDA ifanelekile kwi-foam eqinile efakwe isifutho?

    Yebo, ukusebenza kwayo okulinganiselwe kunciphisa ingozi yokuvaleka kwe-nozzle uma kuqhathaniswa nama-catalyst asheshayo njenge-TMEDA.

    Ngingayisebenzisa kanjani i-TMPDA ukwehlisa ubuningi be-foam ku-sealant ye-foam enengxenye eyodwa?

    Engeza u-0.3–0.5 phr ukuze wandise ukusebenza kahle kokuvunguza; lungisa inkomba ye-isocyanate ngokufanele.

    Ingabe i-TMPDA ibangela ukuphuzi kwezingubo ezicacile?

    Ama-aromatic angaphansi kwama-aromatic amine, kodwa kungenzeka ukuthi kube phuzi ngaphansi kwe-UV; sebenzisa nama-UV absorbers ekusetshenzisweni kwangaphandle.

    Ukukhiqizwa kwami ​​kudinga i-amine enephunga eliphansi ukuze kusetshenziswe i-polyurethane floor screed. Ingabe i-TMPDA iyamukeleka?

    Yebo, i-TMPDA inephunga elincane le-amine, eliphansi kakhulu kune-TMEDA noma i-PMDETA.

    Ingabe i-TMPDA ingasetshenziswa kanye nama-catalysts e-organotin?

    Impela, isebenzisana ne-tin ukunciphisa isidingo se-tin iyonke ngo-30-50% kuma-elastomer.
