Ilaphu le-Spunbond eliqhelekileyo lase-US elibuyisela umlilo

Ngenxa yophuhliso oluqhubekayo lolwakhiwo lwasezidolophini kunye nezibonelelo zothutho, isixa samalaphu angalukwanga asetyenziselwa ukuhombisa ngaphakathi kunye nekhabhinethi, njengamakhethini, amakhethini, izigqubuthelo zodonga, ukuziva, kunye neebhedi, zikhula imihla ngemihla. Noko ke, kwangaxeshanye, imililo ebangelwa yimililo yezo mveliso iye yabakho enye emva kwenye. Amazwe aphuhlileyo kwihlabathi jikelele sele ebeke phambili iimfuno zokunqanda amadangatye kwimpahla yangaphandle kwangeminyaka yoo-1960, kwaye aqulunqa imigangatho ehambelana nedangatye kunye nemimiselo yomlilo. UMphathiswa woKhuseleko loLuntu lwaseChina uye waqulunqa imimiselo yokhuseleko lomlilo, echaza ngokucacileyo ukuba amakhethini, i-sofa covers, iikhaphethi, njl. Ngoko ke, uphuhliso kunye nokusetyenziswa kwe-flame-retardant nonwoven product in China ziye zaphuhliswa ngokukhawuleza, zibonisa uphuhliso oluhle.

Umphumo we-flame retardant we-non-wovenwod iphumelele ngokudibanisa i-flame retardants. Ukuze i-retardants yomlilo isetyenziswe kwiilaphu ezingalukwanga, kufuneka zihlangabezane nale miqathango ilandelayo:

(1) Ubuthi obuphantsi, ukusebenza kakuhle, kunye nokuqina, okunokwenza ukuba imveliso ihlangabezane neemfuno zemigangatho yokubuyiswa komlilo;

(2) Uzinzo oluhle lwe-thermal, ukuveliswa komsi ophantsi, ofanelekileyo kwiimfuno zeempahla ezingalukwanga;

(3) Ukunganciphisi kakhulu ukusebenza kwasekuqaleni kwamalaphu angalukwanga;

(4) Ixabiso eliphantsi linenzuzo ekunciphiseni iindleko.

Ukugqitywa kwedangatye elibuyiswayo kwamalaphu angalukwanga: Ukugqibezela ukubuyiswa komlilo kufezekiswa ngokulungisa izithinteli zomlilo kwilaphu eliqhelekileyo elingalukwanga ngokufaka i-adsorption, ukudityaniswa kweekhemikhali, i-non-polar van der Waals force bonding, kunye nokudibanisa. Xa kuthelekiswa nokuguqulwa kwefayibha, le ndlela inenkqubo elula kunye notyalo-mali oluncinci, kodwa inokusebenza kakubi kokuhlamba kwaye inempembelelo ethile kwimbonakalo kunye nokuvakalelwa kweendwangu ezingalukwanga. Ukugqitywa kwe-flame retardant kunokuqhutywa ngokudipha kunye nokutshiza.

Iimveliso zelaphu ezingalukwanga ezinqandwa ngumlilo zinezi zicelo zilandelayo.

(1) Isetyenziselwa ukuhombisa ngaphakathi kunye nakwikhabhinethi, njengamakhethini, iikhethini, iikhaphethi, izigqubuthelo zokuhlala, kunye nezixhobo zokupeyinda zangaphakathi.

(2) Isetyenziswa njengendawo yokulala, enje ngoomatrasi, izigqubuthelo zebhedi, imiqamelo, iikhushini zokuhlala, njl.

(3) Isetyenziswa njengento yokuhombisa eludongeni kunye nezinye izixhobo zokugquma isandi esirhoxisa umlilo kwiindawo zokuzonwabisa.

Ukuthelekiswa kwemveliso ye-flame retardant

Iimpawu zemveliso ezinokudlula uvavanyo lwe-CFR1633 e-United States ziyi-flame retardant, i-anti melting, umthamo omncinci womsi, akukho kukhutshwa kwegesi enetyhefu, umphumo wokuzicima, ukukwazi ukugcina imeko yayo yangaphambili emva kwe-carbonization, ukufunxa ukufuma, ukuphefumla, ukuvakalelwa kwesandla esithambileyo, kunye ne-elasticity ehlala ixesha elide. Ilungele ukuthumela ngaphandle oomatrasi abakumgangatho ophezulu eMelika.

Iimpawu zemveliso ezihlangabezana nomgangatho wovavanyo we-BS5852: Okwangoku, imarike yaseYurophu ineemfuno ezinyanzelekileyo zokunqanda amadangatye oomatrasi befenitshala ethambileyo kunye nezihlalo, ngelixa ifuna ukuva okuthambileyo kunye nokuqina okuhlengahlengiswayo, ukumelana nomlilo okuhle, kunye nokucima ngokuzenzekelayo ngaphakathi kwemizuzwana engama-30. Ikakhulu ifanelekile ukuthunyelwa kwiimarike zaseYurophu, kwaye isetyenziswa ngokubanzi kwiisofa eziphezulu.
