Ilaphu eligqumayo Ilaphu eligqumayo: Unyango lwelaphu elibuyiswa lidangatye

I. Ulwahlulo lwamalaphu anqanda amadangatye.Ilaphu eligqumayo

Amalaphu agada amadangatye anokwahlulwa abe:

1. Ilaphu elihlala lingenamlilo (ukwaluka ifayibha,Ilaphu eligqumayonokuba mangaphi amaxesha, isiphumo sokubuyiswa komlilo asitshintshi)

2. Ilaphu elingenamlilo elinokuhlambeka (ngamaxesha angaphezu kwama-50).

3. Ilaphu elinqanda amadangatye elihlambekayo.

4. Ilaphu elilahliweyo elibuyisela idangatyeIlaphu eligqumayo(ukuhlobisa. Amakhethini, iikhushini zokuhlala, njl.njl.)

Okwesibini, inkqubo yokuvelisa amalaphu e-flame retardant kunye nokuqaliswa kwezongezo zinokwahlulwa zibe: unyango lwe-fiber flame retardant kunye nokugqiba i-flame flame retardant.

Unyango lwelaphu elibuyiswa ngamadangatya:

1. Indlela yokubuyiswa komlilo ibhekiselele ekongezweni kwezinto ezizitshisayo (ezifana ne-polyester, i-cotton fiber) kunye nenye i-flame retardant ukuthintela iqela elikhululekile kwinkqubo yokutsha; Okanye utshintshe inkqubo ye-fiber pyrolysis, ukukhuthaza i-carbonization dehydration; Ezinye zizithinteli zomlilo eziqhekezayo zize zikhuphe iigesi ezinokutsha ezigquma umphezulu wemicu nezisebenza njengomqobo emoyeni.

2) Ukuguqulwa kwe-flame retardant yesilika yokuqala.

Ukugqitywa kokubuyiswa komlilo welaphu:

1. Indlela yokubuyiswa komlilo.

I-1) Umgaqo wokugubungela ifilimu: i-flame retardant kwiqondo lokushisa eliphezulu inokwenza i-glassy okanye i-foam layer, kunye ne-insulation. Ukufakwa kweoksijini. Ukuthintela ukuvuza kwegesi evuthayo, dlala indima yokukhusela umlilo.

I-2) i-theory yegesi engenakutsha: ukuchithwa kwe-thermal ye-flame retardant kuvelisa i-gas engatshiyo, ukwenzela ukuba i-concentration yegesi evuthayo emva kokubola kwe-cellulose iwela ngaphantsi komda ophantsi wokutsha.

Umgaqo wokufunxa ubushushu: I-flame retardant kwiqondo eliphezulu, ivelisa ukusabela kobushushu, ukunciphisa ubushushu, ukuthintela ukusasazeka kokutsha. Ukongezelela, emva kokugqiba ingubo, amandla okushisa ahanjiswa ngokukhawuleza ngaphandle, okubangelwa ukuba i-cellulose ayikwazi ukufikelela kwiqondo lokushisa.

2. Indlela yokugqiba yelaphu elibuyiswa ngamadangatye.

1) I-Leaching roasting: Yenye yezona nkqubo zisetyenziswa kakhulu kwinkqubo yokugqiba i-flame retardant. Inkqubo idipha - pre - baking - post - unyango. Ulwelo oluqengqelekayo lubandakanya iiretardants zomlilo, ii-catalysts, iiresin, ii-agent zokumanzisa, izinto ezithambisayo, ezenziwe njengezisombululo ezinamanzi okanye ii-emulsions.

2) I-impregnation kunye nokubhaka (i-absorption) : i-tissue ifakwe kwi-flame retardant ixesha elithile, ize yomiswe kwaye ibhakwe, ukwenzela ukuba isisombululo se-flame retardant sithathwe yi-fiber polymerization.

3) Indlela ye-solvent ye-Organic: ukusetyenziswa kwe-insoluble flame retardant, kunye neenzuzo zokugqitywa kwe-flame retardant. Ngokwenza umsebenzi, ingqalelo kufuneka ihlawulwe kwi-toxicity kunye nokusebenza kokutsha kwe-solvent.

I-4) Indlela yokugqoka: i-flame retardant ixutywe ne-resin, kwaye i-flame retardant igxininiswe kwindwangu ngokudibanisa i-resin. Ngokwezixhobo zoomatshini zahlulwe ngendlela yokukhuhla kunye nendlela yokugalela.
