Yiziphi Izimpawu Ze-PU Foam Technology Yezihlalo Zemoto?

1. Hlukanisa ngokushisa kwesikhunta

1)Igwebu elishisayo:

Ngemva kokuphonswa kuqediwe, isikhunta sifakwa kuhhavini ngo-220-250℃(hhayi ngaphansi kuka-180℃), futhi ngemva kokuqedwa kokusabela, iyakhishwa futhi idilizwe.

Izinzuzo: ukuminyana kwegwebu eliphansi, ukusebenza kahle kokuguga kokushisa, asikho isidingo sokuvuleka okuhlukene.Izindleko zesikhunta ziphansi.

Ukungalungi: ukusetshenziswa kwamandla aphezulu.Imbobo yokukhipha umoya kulula ukukhiqiza "ikhanda lekhowe", okuholela ekumosheni okuningi kwezinto zamakhemikhali.Kamuva ukuhlanza endaweni nokugcinwa kwemishini kuba nzima kakhulu.

2)Kubanda amagwebu

Ngokuvamile yakhelwe njenge-amulti-station turntable umugqa wokukhiqiza.Isikhunta ngokuvamile sishiselwa ku-45-70℃ngomshini wokushisa wesikhunta, bese wehliswa ngemuva kokuthi ukusabela kwegwebu kuqedwe ngokuthulula impahla ye-PU.Ngemuva kokudilizwa, umkhiqizo udinga ukusebenzisa i-foam breaker ukusiza ukuvula umgodi.Izinzuzo: Ukusetshenziswa kwamandla okuphansi, okokusebenza okuhlanzekile nokugcinwa kalula Okubi: Imishini iyinkimbinkimbi kakhulu futhi nezindleko zemishini ziphezulu.Ukusebenza kokushisa kwegwebu kumaphakathi.

2. Hlukanisa ngokukhangiswa kwendawo

1) Igwebu elinqunu:

Iqanjwe ngokuphambene nomqondo we-adsorption kanye negwebu, indwangu ngeke ibekwe ngaphambili ekubunjweni, futhi ubuso bomkhiqizo onamagwebu yisendlalelo se-PU.Ama-noodle wonke ahlanganiswa ngemva kokucubungula.Izimoto ezithwala abantu zisebenzisa kakhulu le nqubo yokukhihliza amagwebu.

2) I-Adsorption egcwele amagwebu

Ngaphambi kokuthulula, qala ngokubeka indwangu emgodini wesikhunta, uyenze ilingane ngokuphelele ngokumunca kanye ne-adsorption, bese uthela impahla ye-PU.Ngemuva kokukhipha amagwebu, ungqimba olungaphezulu lomkhiqizo we-PU obunjiwe lunamathele ngokuqinile endwangu.Izihlalo zemishini yokwakha maningi amathuba okuthi zisebenzise le nqubo yokukhihliza amagwebu.

3. Hlukanisa ngobulukhuni

1) Igwebu elilodwa lokuqina:

Igwebu elilula kakhulu, ifomula eyodwa, ukuthela okukodwa, azikho ezinye izindlela ezisizayo, futhi imikhiqizo yegwebu ethulwayo inobunzima obubodwa kuphela.

2) Igwebu eliqinile eliphindwe kabili

Igwebu eliqinile kabili liyindawo yokuthengisa izimoto eziningi zikanokusho.Indawo yokugibela ithambile, futhi izindawo zokusekela ezinhlangothini zombili zinzima, ezinganikeza induduzo eyengeziwe.Indlela yokufeza lokhu ukusebenzisa indawo yokuhlala kanye nezinhlangothi ezimbili zendawo ukuze uthele ngokuhlukana, futhi uzuze ukuhlukaniswa kobunzima obukabili noma ubulukhuni obuningi bomkhiqizo ngokubeka isikhunta e-engeli, wengeze umkhombe wezinto ezibonakalayo phakathi amaphiko amabili nendawo yokuhlala, futhi wengeza ukufaka ezinhlangothini zombili zegwebu..Le nqubo yokwenza amagwebu ingaphinda ifinyelele ubulukhuni obuthathu, kodwa ngokuvamile hhayi ngaphezulu.Embonini, kubizwa nangokuthi i-double-density foaming, empeleni okuwukushelela kolimi.Inhloso yenqubo ukuthola ubulukhuni obuhlukene, hhayi ukuminyana.Futhi ngezinye izikhathi ukuminyana okukodwa kungenza ubulukhuni obubili obuhlukene.Abakhiqizi abawazi kahle le nqubo yokukhihliza amagwebu ngokuvamile badinga ukuhlonyiswa abasebenzi bezobuchwepheshe abanekhono lokulungisa izinto ezihlanganisiwe, ngenxa yokuthi badinga ukwazi izinguquko nokulungiswa kwamafomula amaningi.
