ETPU Inqubo Yokwakhiwa KwePlastiki Ephansi

ETPU (Inwetshiwe i-thermoplastic polyurethane) yinto efana ne-popcorn. Ngemva kokuba ngaphansi kwengcindezi nokwelashwa ukushisa, umthamo TPU izinhlayiya zizokwanda izikhathi ezingu-10, zenze izinhlayiya ze-elliptical non-crosslinked foaming ezinama-bubbles avaliwe ngaphakathi, afana ne-"popcorn". ETPU impahla inokuqina okuphezulu futhi ingamunca ngempumelelo umthelela futhi inciphise ukulimala okubangelwa ukuwa nezingozi. Lo mkhiqizo usetshenziswa kakhulu ezinkundleni zemidlalo, ezinkundleni zemidlalo zezikole, futhi ngokuya ngokuya emizileni yokuqina yasemadolobheni, emigwaqweni eluhlaza, nasezindaweni zokudlala zasenkulisa.

Inqubo Yokwakha Ethize

Lungiselela Izinto

I-Primer, i-adhesive yengxenye eyodwa, ETPU ama-granules, upende osuselwe emanzini we-polyurethane, i-engela grinder, umshini wokufutha ongenawo umoya, i-ayina kagesi, ummese webhani oshisayo, irola, ibhulashi, izinsimbi zokulinganisa, i-mixer kagesi, iphepha lokuhlobisa, njll.

Lungiselela Isisekelo

Ukhonkolo osanda kuthululwa kufanele ube nesikhathi sokuphulukiswa (okungenani izinsuku ezingama-28 ehlobo, nokwandiswa okufanele ebusika). Imigodi nemifantu kufanele kulungiswe ngodaka lukasimende. Isisekelo sesisekelo kufanele siqine futhi silingane, futhi noma yikuphi ungqimba oluvulekile endaweni kakhonkolo kufanele kugaywe ngomshini wokugaya. Ibanga lamandla esakhiwo akufanele libe ngaphansi kuka-C20. Hlanza kahle umhlabathi, ususe konke ukungcola okunjengamafutha, izinsalela zikawoyela, izinsalela zikapende, amakhemikhali, nodaka. Hlola umswakama womhlaba, futhi umswakama kufanele ube ≤8% ngaphambi kokudlulela esinyathelweni esilandelayo sokwakha (sebenzisa i-tape ebonakalayo ngokuqinile phansi, futhi ngemva kwamahora amane, akufanele kube namaconsi amanzi abonakalayo ku-tape).

I-Primer Coating engangeni manzi

Ngemuva kokuthi iphansi lilinganisiwe futhi lihlanjululwe, ungaqhubeka nokugoqa ku-primer engangenisi amanzi ephezulu. Lokhu kusiza ukuthuthukisa ikhono lokubopha phakathi kwesisekelo kanye nongqimba olungaphezulu, futhi kuqinisa ukuvinjelwa kwamanzi nokubopha. Sebenzisa i-roller ukuze usebenzise i-primer, uqinisekise ukuthi indawo engaphezulu imanziswe ngokuphelele ngaphandle kwamachashazi aphuthelwe. Gwema ukusebenzisa i-primer eningi, ngoba ingabangela amabhamuza phansi epulasitiki, okuthinta kokubili ubuhle kanye nekhwalithi. Le nqubo iqukethe amajazi amabili: ijazi lokuqala lokungena nokuphulukisa, futhi ijazi lesibili lokuvala.

Ukuxuba Izinhlayiya

Thela izinhlayiya esitsheni esivaliwe. Engeza i-adhesive-component eyodwa ezinhlayiyeni ngesilinganiso se-2.5-4: 1 (izinhlayiya zokunamathela). Hlanganisa ingxube imizuzu emi-5 ukuya kweyi-10, noma ize ixutshwe kahle.

ETPU ukubekwa kwe-granule

Ngaphambi kokubeka izinhlayiya, sebenzisa ungqimba lwe-adhesive high-bonding. Ngemva kokuxuba kahle izinhlayiya, zithele phansi. Sebenzisa i-PU trowel enamazinyo ukuze usakaze izinhlayiya ngokulinganayo. Bese, sebenzisa umshini okhethekile wokugandaya ukuze uleveli ngomshini futhi uhlanganise izinhlayiya kugqinsi oluklanyelwe, uqinisekise ukulawula ubuningi nokujiya. Uma kukhona izindawo ezingalingani, qhubeka uzilinganise.

Roll enamathela amanzi-based polyurethane 

Ngemva kwamahora angu-48 omiswe we ETPU ama-granules, hlanganisa kahle izingxenye A no-B ze-polyurethane esekwe emanzini imizuzu emi-3, bese ufafaza ngokulinganayo usebenzisa umshini wokufutha ongenawo umoya.

Ukuqapha

1. Izinga lokushisa elizungezile endaweni yokwakha kufanele libe ngaphezu kuka-5℃, futhi umswakama ohlobene kufanele ube ngaphansi kwama-80% wokwakhiwa.
2. Umakhi kufanele agcine amarekhodi esizinda sokwakha, isikhathi, izinga lokushisa, umswakama ohlobene, ukwelashwa kwendawo yaphansi, izinto zokwakha, njll., ukuze asetshenziswe esikhathini esizayo.
3. Amalangabi avulekile anqatshelwe ngokuphelele endaweni yokwakha.
4. Ukuze uvimbele ukungcoliswa kwemiphetho yokwakha futhi ugcine umugqa oqondile ngokuphelele (noma umngcele ngendawo engahlanganisiwe), i-tape yokuzivikela kufanele isetshenziswe. Naka inhlanzeko lapho uphatha izithako namathuluzi okugwema ukungcola.
5. Ngesikhathi sokwakha, landela izimiso "zokulungiselela isithako esizinikezele, amaqoqo amancane amaningi, kanye nokunikezwa okuqhubekayo". Lungiselela futhi usebenzise ingxube ngokushesha, futhi usebenzise izinhlayiya ezixubile phakathi nehora elingu-1. Sebenzisa i-primer elungiselelwe phakathi nemizuzu engama-30.
