I-polyurethane adhesive glue

5. Ukusetshenziswa:

(1) Ukwelashwa kwangaphambili: ingaphezulu le-adhesive liyahlanzwa.

(2) ukulinganisa: sebenzisa i-sawtooth scraper ukuze usebenzise i-glue ebusweni be-adhesive ngokulinganayo, futhi ungasebenzisa i-mechanical rolling coating, ayikwazi ukusebenzisa ibhulashi lebhulashi (i-glue viscosity inkulu), inani lokuxubha elingaba ngu-250g/m2, ngokuqondile ngokusho isimo sangempela silawula inani leglue.

(3) inhlanganisela: emva ingcina kungaba ingcina esiyinhlanganisela.

(4) ngemva kokwelashwa: ngoba le glu iwukunamathelisa amagwebu, lapho ungqimba olunamathelayo lwelashwa, ingcina ingabholwa emgodini omncane we-adhesive, idlale indima yokubambelela, ikhulise amandla okubopha, futhi kufanele icindezelwe. ngemva kokuhlinzwa.

I-polyurethane foam

Imingcele yomkhiqizo

Imininingwane yokupakisha

Izici

Inezici zokusebenza okuphezulu, ukwakhiwa okulungile, ukugwebu ngemva kokuphulukiswa, ukungancibiliki nokungancibiliki, ukumelana nokushisa okuphezulu nokuphansi.

Ububanzi besicelo

Ukukhiqizwa kweminyango engashi, iminyango emelene nokweba, iminyango yasendlini, izinto ezibandayo, kanye nezinto ezihlukahlukene ezikwazi ukumelana nomlilo nezishisayo (uboya bedwala, uboya be-ceramic, uboya bengilazi obucwebezelayo, ipulasitiki ye-polystyrene foam, njll.) ukuze kuhlanganiswe.Ukunamathela kwensimbi kuya kwensimbi.

Iziyalezo

1. Isimiso sokuphulukisa: Lokhu okunamathelayo kuyingcina enengxenye eyodwa engancibiliki, ephulukiswa umswakama omuncwa emoyeni nangaphezulu kwe-adherend.

I-2.Ukwelashwa okungaphezulu kwe-adherend: susa amafutha nothuli ebusweni bokunamathela.Amabala kawoyela amaningi angahlanzwa nge-acetone noma i-xylene.Uma kungekho ibala lamafutha, akudingekile ukuhlanza.Isikhathi, uma kunesidingo, fafaza inkungu encane yamanzi endaweni yenjoloba ngesifutho.

I-3.I-Glue coating: Sebenzisa i-zigzag scraper ukuze usebenzise ngokulinganayo i-glue ebusweni be-adherend.I-glue yomshini nayo ingasetshenziswa, kodwa ukuxubha akudingekile (i-grease viscosity inkulu), futhi inani lokumboza lingaba ngu-150-250g /㎡.Ingaphezulu le-adherend lingancishiswa kancane, futhi ubulukhuni obungaphezulu bungakhuphuka kancane, okungukuthi, inqobo nje uma izindawo zokunamathela ezimbili zihlangana futhi zingathintana ngokugcwele ne-glue, kancane inani lokumboza, ngcono, ngoba i-glue eyengeziwe isetshenziswa, kulapho Umswakama omuncwa phezu kwe-adherend unomkhawulo, ozothinta isikhathi sokuphulukisa.Uma inani leglue elisetshenzisiwe lidingeka, inani elincane lenkungu yamanzi lingafuthwa ngendlela efanele.

I-4.compound: inganamathiselwa

I-5.Post-treatment: Ngenxa ye-adhesive enegwebu yale rubber, lapho ungqimba olunamathelayo lwelashwa, i-glue ingakwazi ukudonsa phansi ama-micropores we-adherend, edlala indima yokubambelela futhi ikhulise amandla okubopha.Impahla ihlanganiswe futhi ingathukululwa ngemuva kokwelashwa (ingcindezi icishe ibe ngu-0.5kg-1kg / cm2).

I-6.Ukuhlanza ithuluzi kungasebenzisa i-ethyl acetate solvent.

Izinyathelo zokuzivikela

1, Sebenzisa i-spatula e-serrated ye-scraper, njengepuleti eliyisicaba.Kodwa-ke, uma i-glue isetshenziswa kanzima kakhulu, ngeke kube khona i-glue esele endaweni yokugqoka.Uma i-glue isetshenziswa kancane kakhulu, i-glue izoba yimfucuza eningi kakhulu.I-zigzag scraper iqinile njengoba injalo, futhi iglue eshiywe yi-sawtooth inkulu.

2, Izindawo ezimbili zokubopha okufanele zihlanganiswe kumele zinamathiselwe ohlangothini olulodwa.

indlela yokugcina

Lo mkhiqizo kufanele ugcinwe endaweni epholile futhi emnyama ngesikhathi sokugcina.Ngokuvamile ezindlini zokugcina impahla, isikhathi sokugcina siwunyaka owodwa.Ngemuva kokusetshenziswa ngakunye kweglue, umgqomo oneglue owedlulele kufanele uvalwe futhi ugcinwe, futhi ungqimba olungaphezulu lwe-glue liquid luzoqina futhi luqine ngenxa yokungena komswakama.Uma ingasetshenziswa isikhathi eside, kufanele ivalwe nge-nitrogen.
