Indwangu yokuvikela i-Insulating Indwangu: Ukwelashwa kwendwangu ebuyisela amalangabi

I. Ukwahlukaniswa kwezindwangu ezingabambezeli ilangabi.Insulating Indwangu Indwangu evikelayo

Izindwangu ezivimbela amalangabi zingahlukaniswa zibe:

1. Indwangu ehlala unomphela ebambezela ilangabi (ukwaluka i-fiber,Insulating Indwangu Indwangu evikelayokungakhathaliseki ukuthi izikhathi ezingaki, umphumela we-flame retardant awushintshiwe)

2. Indwangu ekwazi ukugezeka (izikhathi ezingaphezu kwezingu-50) ekwazi ukumelana nomlilo.

3. Indwangu engasheshi ukuwasheka nelangabi.

4. Indwangu elahla amalangabi elahlayoInsulating Indwangu Indwangu evikelayo(okuhlobisa. Amakhethini, amakhushini ezihlalo, njll.)

Okwesibili, inqubo yokukhiqiza izindwangu ezivimbela amalangabi kanye nokwethulwa kwezithasiselo zingahlukaniswa zibe: ukwelashwa kwe-fiber flame retardant kanye nokuqedwa kwe-flame retardant.

Ukwelashwa kwendwangu ye-flame retardant:

1. Indlela yokubuyiswa kwamalangabi ibhekisela ekwengezweni kwe-prefilament ethile ezishisayo (efana ne-polyester, i-cotton fiber) ne-retardant ethile yelangabi ukuze kuvinjelwe iqembu elikhululekile enqubweni yokuvutha; Noma shintsha inqubo ye-fiber pyrolysis, ukhuthaze ukuphelelwa amandla kwamanzi nge-carbonization; Ezinye ziyizinto ezivimbela amalangabi ezibhidlizayo futhi zikhiphe amagesi angashi amboza imicu futhi asebenze njengesithiyo emoyeni.

2) Ukuguqulwa kwe-flame retardant kosilika wokuqala.

Ukuqedwa kwe-textile retardant flame:

1. Indlela yokubuyisela amalangabi.

I-1) Isimiso sokumboza ifilimu: i-flame retardant ekushiseni okuphezulu ingakha ungqimba lwegwebu oluyingilazi noma oluzinzile, olunokwahlukanisa. Ukufakwa kwe-oxygen. Vimbela ukuvuza kwegesi evuthayo, dlala indima yokuvikela umlilo.

I-2) ithiyori yegesi engashi: ukubola okushisayo kwe-flame retardant kukhiqiza igesi engashi, ukuze ukuhlushwa kwegesi evuthayo ngemva kokubola kwe-cellulose iwe ngaphansi komkhawulo ophansi wokuvutha.

Isimiso sokumunca ukushisa: I-flame retardant ekushiseni okuphezulu, ikhiqiza ukusabela kokumunca ukushisa, yehlisa izinga lokushisa, ivimbele ukusabalala kokusha. Ngaphezu kwalokho, ngemva kokuqeda indwangu, amandla okushisa asakazwa ngokushesha ngaphandle, okuholela ekutheni i-cellulose ayikwazi ukufinyelela izinga lokushisa lomlilo.

2. Indlela yokuqeda yendwangu evimbela ilangabi.

I-1) I-Leaching roasting: Kungenye yezinqubo ezisetshenziswa kakhulu ekuqedeni inqubo yokuqeda i-flame retardant. Inqubo iwukucwilisa - pre - baking - post - treatment. Uketshezi olugoqiwe ngokuvamile luhlanganisa izinqamuleli zamalangabi, ama-catalyst, ama-resin, izinto ezimanzisa, izinto ezithambisayo, ezakhiwe njengezisombululo ezinamanzi noma ama-emulsion.

I-2) I-impregnation nokubhaka (ukumuncwa) : izicubu zicwiliswe ekukhanyeni komlilo isikhathi esithile, bese zomiswa futhi zibhakwe, ukuze isisombululo se-flame retardant sithathwe yi-fiber polymerization.

3) Indlela ye-solvent ye-Organic: ukusetshenziswa kwe-retardant yomlilo engancibiliki, enezinzuzo zokuqeda i-flame retardant. Ngokwenza njalo, kufanele kuqashelwe ubuthi kanye nokusebenza komlilo kwe-solvent.

I-4) Indlela yokugqoka: i-flame retardant ixubene ne-resin, futhi i-flame retardant igxiliwe kwendwangu ngokuhlanganisa i-resin. Ngokusho kwemishini yomshini ihlukaniswe ngendlela yokukhuhla kanye nendlela yokuthela.
