Insulating nsalu Insulating nsalu: Chithandizo cha lawi retardant nsalu

I. Gulu la nsalu zotchinga moto.Insulating nsalu Insulating nsalu

Nsalu zoletsa moto zimatha kugawidwa m'magulu awiri:

1. Nsalu yosatha yoletsa moto (kuluka ulusi,Insulating nsalu Insulating nsaluzilibe kanthu kangati, mphamvu yobwezeretsanso lawi sisintha)

2. Nsalu yotsuka (ka 50) yosagwira ntchito yoyaka moto.

3. Nsalu yotchinga ndi moto yotha kuyanika.

4. Nsalu yotaya moto yoyaka motoInsulating nsalu Insulating nsalu(zokongoletsa. Makatani, makashini a mipando, ndi zina zotero)

Chachiwiri, kupanga nsalu zotchingira moto ndi kuyambitsa zowonjezera zitha kugawidwa m'magulu awiri: mankhwala oletsa moto wa fiber ndi kumalizitsa kwamoto wamoto.

Chithandizo cha nsalu yotchinga moto:

1. Makina oletsa moto amatanthawuza kuwonjezeredwa kwa prefilament yoyaka yokha (monga poliyesitala, ulusi wa thonje) yokhala ndi zoletsa moto kuti ziletse gulu laulere pakuyaka; Kapena kusintha CHIKWANGWANI pyrolysis ndondomeko, kulimbikitsa madzi m'thupi carbonization; Zina ndi zoletsa malawi amene amasweka ndi kutulutsa mpweya wosayaka umene umakuta pamwamba pa ulusiwo n’kukhala ngati chotchinga mpweya.

2) Kusintha koletsa moto kwa silika woyambirira.

Kumaliza kwa Textile retardant:

1. Flame retardant mechanism.

1) Mfundo yophimba filimu: chowotcha moto pa kutentha kwakukulu chikhoza kupanga chithovu chagalasi kapena chokhazikika, chokhala ndi kutsekemera. Kutsekemera kwa okosijeni. Pewani kutuluka kwa gasi woyaka, gwirani ntchito yoteteza moto.

2) chiphunzitso cha gasi chosayaka: kuwonongeka kwamoto wamoto wamoto kumatulutsa mpweya wosayaka, kotero kuti ndende ya gasi yoyaka pambuyo pakuwonongeka kwa cellulose imagwera pansi pa malire apansi a kuyaka.

Mfundo yamayamwidwe a kutentha: Kuchepetsa kutentha kwa moto pa kutentha kwakukulu, kumapangitsa kuyamwa kwa kutentha, kuchepetsa kutentha, kuteteza kufalikira kwa kuyaka. Kuonjezera apo, atamaliza nsaluyo, mphamvu ya kutentha imagawidwa mofulumira kunja, zomwe zimapangitsa kuti cellulose isafike kutentha kwa moto.

2. Njira yomaliza ya nsalu yotchinga moto.

1) Kuwotcha: Ndi imodzi mwamachitidwe omwe amagwiritsidwa ntchito kwambiri pakumaliza koletsa moto. Njirayi ndikuviika - pre - kuphika - post - mankhwala. Madzi okulungidwawo nthawi zambiri amakhala ndi zoletsa moto, zopangira, zotulutsa, zonyowetsa, zofewetsa, zopangidwa ngati njira zamadzimadzi kapena ma emulsion.

2) Impregnation ndi kuphika (mayamwidwe) : minofu ankawaviika lawi retardant kwa nthawi inayake, ndiyeno zouma ndi kuphika, kuti lawi retardant yankho odzipereka ndi CHIKWANGWANI polymerization.

3) Organic zosungunulira njira: ntchito insoluble lawi retardant, ndi ubwino lawi retardant kumaliza. Pochita, chidwi chiyenera kuperekedwa ku kawopsedwe ndi kuyaka kwa zosungunulira.

4) Njira yophikira: chowotcha chamoto chimasakanizidwa ndi utomoni, ndipo chowotcha chamoto chimakhazikika pa nsalu pomangirira utomoni. Malinga ndi makina zida lagawidwa kukanda njira ndi kuthira njira.
