Ukusetshenziswa kwe-polyurethane esebenzayo ye-hot melt adhesives

Ngenxa yezakhiwo ezinhle kakhulu zokunamathelisa okuncibilika kwe-polyurethane okushisayo, kungenzeka ukushintshela kuma-adhesive ancibilikayo aphilisa umswakama ukuze kuhlanganiswe lapho okunamathiswa okuncibilika okushisayo noma okunamathelayo okusebenzayo ekuqaleni kwakusetshenziselwa ukubopha. Ukusebenza. Ngenxa yokuthi kufanele ihlukaniswe ngokuqinile nomswakamo ngesikhathi sokwenziwa, ukugcinwa nokulinganisa, ukunyuswa kwayo kunqunyelwe ngezinga elithile, futhi akuzange kudayiswe ngamanani amakhulu. Eminyakeni yamuva, lezi zinkinga ziye zanqotshwa kancane kancane ngenxa yempumelelo yezobuchwepheshe nemishini, eye yathatha indawo yezinto ezinamathelayo ezincibilikayo ezishisayo. Ukusetshenziswa kwayo kuzoba kubanzi kakhulu esikhathini esizayo.

1.Polyurethane Adhesives for Woodworking

Ukuphulukisa izinamathiselo ze-polyurethane ezisetshenziswa embonini yezinkuni ziwuketshezi futhi zisetshenziswa ekamelweni lokushisa. Ngokuvamile inamandla okubopha okuphezulu, ukuguquguquka okuhle nokumelana namanzi, futhi ingahlangana nama-substrates amaningi angewona amapulangwe (njengemicu yendwangu, izinsimbi, amapulasitiki, irabha, njll.). Amandla nokuqina kwezinamathiselo ze-polyurethane kungahlangabezana nezidingo zokuhlola eziqine kakhulu.

2.Izinamathiselo zePolyurethane zeZindwangu

Izidingo ezijwayelekile zokunamathela okuncibilika okushisayo ekucutshungulweni kwendwangu azinambala futhi azinaphunga, ukuthungwa okuthambile, ukubopha okusheshayo, ukumelana nokuhlanza okomile nokumanzi, i-glue ayikwazi ukuphazamisa indwangu, ukumelana nokukhanya, njll. Izinamathiselo ze-polyurethane zihambisana ngokugcwele nokucubungula kwendwangu.

3.Polyurethane Adhesives for Packaging

Ukupakisha okuguquguqukayo kulula futhi kulula, isikhathi sokulondoloza isikhathi eside, inhlanzeko, kulula ukuyigcina nokuthutha, kulula ukuyihlakaza, udoti omncane kanye nomphumela omuhle weshalofu. Ngenxa yokusebenza kwayo okuhle kakhulu, i-polyurethane adhesive ingahlanganisa izinto zefilimu zezakhiwo ezahlukene. Ifilimu eyinhlanganisela yokupakishwa okuguquguqukayo enezakhiwo ezihlukahlukene ezifana nokumelana nokubanda, ukumelana nowoyela, ukumelana namakhemikhali, ukukhanya nokumelana nokugqoka kungatholakala ndawonye.

I-4.I-Polyurethane Adhesive for Construction

Ngaphezu kwezinzuzo zokungewona ubuthi, okungangcolisi, nokusetshenziswa kalula, izinamathiselo ze-polyurethane nazo zinezinzuzo ezinye izinamatheliso ezingakwazi ukufana nazo, okungukuthi ukumelana nokushisa okuphansi okuhle kakhulu, ukumelana ne-solvent, ukumelana nokuguga, ukumelana ne-ozone kanye nokumelana namagciwane. idlala indima ebalulekile ekusetshenzisweni kwezinto zokupakisha.

5.Polyurethane Adhesives for Automobiles

Ukwethulwa kwenani elikhulu lezinsimbi ezingasindi, izinto eziyinhlanganisela namapulasitiki ezakhiweni ezintsha zezimoto kubangele ukukhula okuqhubekayo kwezinamatheliso zezimoto nama-sealant. Izinamatheliso ze-polyurethane ezisetshenziswa kakhulu ezimotweni ikakhulukazi ziyingxenye eyodwa emanzi Ukwelapha i-polyurethane sealants; izinto zokunamathisela zesakhiwo zokuhlanganisa ingilazi ye-fiber eqinisiwe kanye nezinto ezihlanganisiwe zokubumba amashidi, izinto zokunamathisela ezinezingxenye ezimbili ze-polyurethane izingxenye zangaphakathi nezinamatheliso ze-polyurethane ezisekelwe emanzini, njll.

I-PurKinginikeza okunamathelayo okuncibilika okushisayo okusebenzayo kwama-polyolefin nama-polyurethanes ngamafomethi ahlukahlukene wokunikezela, okuhlanganisa okunamathelayo okuncibilika okushisayo okusebenzayoifenisha,izindwangu,izimoto zangaphakathi, izinto zokwakha, emaphaketheni epulasitiki, njll. - ukuhlinzeka ngezidingo eziphakeme kakhulu zekhwalithi nokubukeka.
