Uyini Umehluko Phakathi Kwe-Polyurethane Ne-Epoxy Resin?

1. Ukufana Nomehluko Phakathi Kwe-Polyurethane Ne-Epoxy Resin:

I-Commonality:

1) I-polyurethane ne-epoxy resin ziyizingxenye ezimbili, futhi imishini nezindlela zokusebenza ziyafana;

2) Kokubili kunokumelana okuhle kwe-tensile, akukho ukuqhekeka, akukho ukuwa kanye nezinye izakhiwo;

3) Zombili zinezakhiwo zokumelana nokugqwala ku-asidi eqinile, i-alkali, usawoti kanye nezinto ezihlukahlukene zamafutha;

I-4) Zombili zinezakhiwo zokuvikela uthuli, ukungangeni kwamanzi, ukumelana nokugqoka okuphezulu, ukumelana nokucindezela okukhulu, ukumelana nomthelela nokunye;

Umehluko:

1) I-polyurethane (PU) i-polyphenylene disocyanate ne-polyether polyol.Ixhumene futhi yelashwe phambi kwe-catalyst triethylene diamine ukwenza i-polymer ephezulu.Uma iqhathaniswa ne-epoxy resin, inobuthi kakhulu.

I-polyurethane inezici zokunamathela okuhle, ukwahlukanisa kanye nokumelana nesimo sezulu.Ubulukhuni bungashintshwa ngokulungisa okuqukethwe kwe-disocyanate ne-polyether polyol, futhi ingasetshenziswa ekufakweni kwemishini ehlukahlukene kagesi kanye nekagesi.

2) I-epoxy resin ngokuvamile yakhiwa i-bisphenol A epoxy resin, i-ejenti yokwelapha (i-amine noma i-acid anhydride), i-ejenti eyisizayo, isigcwalisi, njll. Inesikhathi eside sokuphulukisa ekamelweni lokushisa futhi ingelapheka ngokushisa.Ngemuva kokwelashwa, inamandla okubopha okuphezulu nobulukhuni.Ngokuvamile, inkulu futhi ingenziwa ibe sobala ukuze ihlanganise amamojula kagesi nama-diode.

I-polyurethane inokumelana nesimo sezulu esingcono, ayiqhekeki emazingeni okushisa aphezulu naphansi, futhi ibiza kancane.

2. Ukusetshenziswa kwe-polyurethane ne-epoxy resin:

1) I-polyurethane resin:

I-polyurethane resin iyimpahla ye-polymer enamandla amakhulu, ukumelana nokukhala, ukumelana nokugqoka nezinye izici;

Isetshenziswa njengeamarola,amabhande okuthutha, amapayipi, izingxenye zezimoto,izicathulo zezicathulo, isikhumba sokwenziwa, izintambo nezintambo nezitho zokwenziwa zezokwelapha, njll.;

Ukwakhiwa kwemikhiqizo yepulasitiki, imikhiqizo yerabha yokwenziwa engagugi, imicu yokwenziwa, imikhiqizo yegwebu eqinile futhi eguquguqukayo, izinto zokunamathisela nezingubo, njll.;

Isetshenziselwa ukuqedela phezulu kwezinkuni ezihlukahlukene, izinto zamakhemikhali, izinto zokuxhumana ngocingo kanye nezinsimbi kanye nezindlela ezihlukahlukene zokuhamba.

2)I-Epoxy resin: ingasetshenziswa futhi kuma-coatings, ama-adhesives, izinto eziyinhlanganisela, njll.

I-epoxy resin coating iwuhlobo lwesitezi esinamandla amakhulu, esingagugi futhi esihle, esinobuhle bokuthungwa okungenamthungo, ukuthungwa okuqinile, ukumelana namakhemikhali okuhle, ukulwa nokugqwala, ukuvikela uthuli, ukulungiswa okulula kanye nezindleko eziphansi zokunakekela.

Amasu ahlukahlukene angaklanywa ngokuya ngezidingo zamakhasimende, njengokumboza ungqimba oluncane, i-self-leveling floor engu-1-5mm ewugqinsi, i-anti-skid ne-wear-resistant floor, i-mortar floor, i-anti-static, i-anti-corrosion floor, njll.

Imikhiqizo ilungele izindawo ezahlukahlukene, njengezindawo zokusebenzela, amagumbi amakhompiyutha, izindawo zokugcina izimpahla, amalabhorethri, amawadi, amagumbi okuhlinzela, ama-workshops, njll.

3. Ijazi langaphambili lilungele ukusetshenziswa ngaphandle, kanti leli lakamuva lifanele ukusetshenziswa endlini;

Ubuthakathaka obukhulu noma ukungalungi kwalokhu kokugcina ukuthi uyesaba imisebe eqinile ye-ultraviolet, futhi izophenduka iphuzi ngaphansi kwemisebe ye-ultraviolet enamandla, okungukuthi, iphele, kodwa ngeke ibole futhi ngeke ithinte ukusetshenziswa;

Kodwa-ke, okwedlule kuthuthukiswe kakhulu ekumelaneni nesimo sezulu kunalokhu kokugcina, ikakhulukazi isikhathi sokuphuzi sangaphambili side kakhulu kunesakamuva, ngakho-ke okokuqala kuvame ukusetshenziselwa izidingo zokwakhiwa kwangaphandle.
