Indwangu ye-spunbond ejwayelekile yase-US ecisha umlilo

Ngenxa yokuthuthukiswa okuqhubekayo kwezakhiwo zasemadolobheni nezokuthutha, inani lezindwangu ezingalukiwe ezisetshenziselwa ukuhlobisa kwangaphakathi nekhabetheni, njengamakhethini, amakhethini, izindonga zodonga, imizwa, nezingubo zokulala, ziyakhula usuku nosuku. Nokho, ngesikhathi esifanayo, imililo ebangelwa ukusha kwemikhiqizo enjalo nayo iye yaba khona ngokulandelana. Amazwe athuthukile emhlabeni wonke abesevele ebeke phambili izidingo zokunqanda amalangabi ezindwangu ekuqaleni kwawo-1960, futhi akha izindinganiso ezihambisanayo zokunqanda amalangabi nemithethonqubo yomlilo. Umnyango Wezokuphepha Komphakathi waseShayina wenze imithetho yokuphepha emlilweni, ebeka ngokucacile ukuthi amakhethini, amakhava osofa, okhaphethi, njll. asetshenziswa ezindaweni zokuzijabulisa zomphakathi kumele asebenzise izinto ezibamba ilangabi. Ngakho-ke, ukuthuthukiswa kanye nokusetshenziswa kwemikhiqizo engalukiwe engancishi ilangabi e-China ithuthuke ngokushesha, ikhombisa umkhuba omuhle wokuthuthuka.

Umphumela we-flame retardant wezindwangu ezingezona ezilukiwe utholakala ngokungeza ama-flame retardants. Ukuze ama-retardants amalangabi asetshenziswe ezindwangu ezingalukiwe, kufanele ahlangabezane nemibandela elandelayo:

(1) Ubuthi obuphansi, ukusebenza kahle okuphezulu, nokuqina, okungenza umkhiqizo uhlangabezane nezidingo zezindinganiso zokunqanda ilangabi;

(2) Ukuzinza okuhle kokushisa, ukukhiqizwa kwentuthu ephansi, okulungele izidingo zezindwangu ezingalukiwe;

(3) Ukunganciphisi kakhulu ukusebenza kwasekuqaleni kwezindwangu ezingalukiwe;

(4) Intengo ephansi inenzuzo ekunciphiseni izindleko.

Ukuqedwa kwelangabi elingalukiwe kwezindwangu ezingalukiwe: Ukuqedwa kwe-flame retardant kufinyelelwa ngokulungisa izinqamuleli zamalangabi ezindwangu ezivamile ezingalukiwe ngokusebenzisa i-adsorption deposition, i-chemical bonding, i-non-polar van der Waals force bonding, kanye ne-bonding. Uma kuqhathaniswa nokuguqulwa kwe-fiber, le ndlela inenqubo elula kanye nokutshalwa kwezimali okuncane, kodwa inokusebenza okungalungile kokuwasha futhi inomthelela othile ekubukekeni nasekuzizweni kwezindwangu ezingalukiwe. Ukuqedwa kwe-flame retardant kungenziwa ngokucwiliswa nokufutha.

Imikhiqizo yendwangu engalukiwe engawohloki amalangabi ngokuyinhloko inalezi zicelo ezilandelayo.

(1) Isetshenziselwa ukuhlobisa kwangaphakathi nekhabetheni, njengamakhethini, amakhethini, okhaphethi, izembozo zezihlalo, nezinto zokugandaya zangaphakathi.

(2) Isetshenziswa njengendawo yokulala, njengomatilasi, izembozo zombhede, imicamelo, amakhushini ezihlalo, njll.

(3) Isetshenziswa njengomhlobiso odongeni kanye nezinye izinto zokufaka umsindo ezinganqamuki ilangabi ezindaweni zokuzijabulisa.

Ukuqhathaniswa kwemikhiqizo ye-flame retardant

Izici zomkhiqizo ezingaphumelela ekuhlolweni kwe-CFR1633 e-United States zivimbela ilangabi, ukunqanda ukuncibilika, inani elincane lentuthu, akukho kukhishwa kwegesi enobuthi, umphumela wokuzicisha ngokwakho, amandla okugcina isimo sawo sangempela ngemva kokukhipha i-carbonization, ukumuncwa umswakama, ukuphefumula, ukuzwa kwesandla esithambile, nokunwebeka okuhlala isikhathi eside. Ilungele kakhulu ukuthumela omatilasi bezinga eliphezulu e-United States.

Izici zomkhiqizo ezihlangabezana nezinga lokuhlola le-BS5852: Njengamanje, imakethe yaseYurophu inezidingo eziyisibopho zokunqanda ilangabi kumatilasi wefenisha ethambile nezihlalo, kuyilapho futhi idinga ukuzwa okuthambile nokuqinile okulungisekayo, ukumelana nomlilo okuhle, nokucisha okuzenzakalelayo phakathi nemizuzwana engama-30. Ilungele ukuthunyelwa emakethe yaseYurophu, futhi isetshenziswa kakhulu kumasofa aphezulu.
