Spunlace nonwoven wa pre-oxygenated fiber
Chiyambi cha Zamalonda:
Nsalu ya pre-oxidized filament nonwoven ndi chinthu chogwira ntchito chopangidwa kuchokera ku pre-oxidized filament (polyacrylonitrile pre-oxidized fiber) kudzera m'njira zopanda nsalu monga kusowa ndi spunlace. Ubwino wake waukulu wagona pakuchedwa kwake kwamoto. Sichifuna zowonjezera zamoto retardants. Ukauika pamoto supsa, susungunuka kapena kudontha. Amangotulutsa mpweya pang'ono ndipo samatulutsa mpweya wapoizoni akayaka, kuwonetsa chitetezo chapadera.
Pakalipano, imakhala ndi kukana kwambiri kwa kutentha kwambiri ndipo ingagwiritsidwe ntchito m'malo a 200-220 ℃ kwa nthawi yaitali, ndipo imatha kupirira kutentha pamwamba pa 400 ℃ kwa nthawi yochepa, kusungabe mphamvu zamakina pa kutentha kwakukulu. Poyerekeza ndi zida zachikhalidwe zolimba zoletsa moto, ndizofewa, zosavuta kuzidula ndikuzikonza, komanso zitha kuphatikizidwa ndi zida zina.
Ntchito yake imayang'ana pa gawo la chitetezo cha moto, monga nsanjika zamkati za masuti amoto, makatani osayaka moto, zingwe zotsekera zotchingira moto, zotchingira zotchingira moto zamkati zamagalimoto, ndi zolekanitsa ma electrode a batri, ndi zina zambiri.
YDL Nonwovens imatha kupanga nsalu zokhala ndi okosijeni zosalukidwa kuyambira magalamu 60 mpaka 800, ndipo makulidwe a m'lifupi mwa chitseko amatha kusinthidwa makonda.
Zotsatirazi ndikuwulula za mawonekedwe ndi magawo ogwiritsira ntchito mawaya omwe ali ndi okosijeni:
I. Zofunika Kwambiri
Kuchedwa kwamoto kwamkati, kotetezeka komanso kopanda vuto: Palibe zowonjezera zoletsa moto zomwe zimafunikira. Simawotcha, kusungunuka kapena kudontha ikayaka moto, koma imangokhala ndi mpweya wochepa. Panthawi yoyaka moto, palibe mpweya wapoizoni kapena utsi woopsa womwe umatulutsidwa, womwe ungalepheretse kufalikira kwa moto ndikukwaniritsa miyezo yapamwamba yachitetezo.
Kutentha kwapamwamba komanso kusunga mawonekedwe abwino: Itha kugwiritsidwa ntchito mokhazikika pamalo a 200-220 ℃ kwa nthawi yayitali ndipo imatha kupirira kutentha pamwamba pa 400 ℃ kwakanthawi kochepa. Sichizoloŵezi kusinthika kapena kupasuka m'madera otentha kwambiri ndipo amatha kukhalabe ndi mphamvu zina zamakina, kukwaniritsa zofunikira za zochitika zotentha kwambiri.
Maonekedwe ofewa komanso osinthika kwambiri: Kutengera njira ya spunlace, chinthu chomalizidwa ndi fluffy, chofewa komanso chomveka bwino pamanja. Poyerekeza ndi singano yokhomeredwa ndi singano yopangidwa ndi okosijeni ulusi wosalukidwa kapena zida zachikhalidwe zolimba zoletsa moto (monga nsalu yagalasi ulusi), ndizosavuta kudula ndi kusoka, komanso zitha kuphatikizidwa ndi zida zina monga thonje ndi poliyesitala kuti muwonjezere mafomu ofunsira.
Ntchito yokhazikika yokhazikika: Imakhala ndi kukana kukalamba komanso kukana kwa asidi ndi alkali. M'malo osungirako tsiku ndi tsiku kapena m'mafakitale ochiritsira, samakonda kulephera chifukwa cha chilengedwe ndipo amakhala ndi moyo wautali wautumiki.
II. Main Application Fields
Pankhani ya chitetezo chaumwini: Monga wosanjikiza wamkati kapena nsalu yotchinga ya masuti amoto, ma apuloni osagwira moto, ndi magolovesi osamva kutentha, sikuti imangokhala ndi gawo loletsa kutentha kwamoto komanso kuteteza kutentha komanso kumathandizira kuvala chitonthozo kudzera mu mawonekedwe ake ofewa. Ikhozanso kupangidwa kukhala bulangeti yopulumukira mwadzidzidzi, yomwe imagwiritsidwa ntchito kukulunga thupi la munthu mwamsanga kapena kuphimba zinthu zoyaka moto pamalo oyaka moto, kuchepetsa chiopsezo cha kuyaka.
Pankhani ya chitetezo cha nyumba ndi nyumba: Amagwiritsidwa ntchito popanga makatani osapsa ndi moto, zotchingira zitseko zosawotcha, ndi zotchingira zotchingira moto, kukwaniritsa miyezo yoteteza moto ndikuchepetsa kufalikira kwa moto m'nyumba. Ithanso kukulunga mabokosi ogawa m'nyumba ndi mapaipi a gasi, kuchepetsa zoopsa zamoto zomwe zimadza chifukwa cha mabwalo amagetsi kapena kutulutsa mpweya.
M'magawo amayendedwe ndi mafakitale: Amagwiritsidwa ntchito ngati nsalu yotchinga moto yokhala ndi mipando, zida ndi ma waya mkati mwagalimoto ndi masitima othamanga kwambiri, kukwaniritsa miyezo yoteteza moto pazida zoyendera ndikuchepetsa kuvulaza kwa utsi wapoizoni pa ngozi zamoto. Itha kugwiritsidwanso ntchito ngati zokutira zoletsa moto pazingwe ndi mawaya kuti malawi amoto asafalikira kumadera ena mizere ikayaka moto.
Kutentha kwambiri kwa mafakitale othandizira minda: M'mafakitale azitsulo, mankhwala, ndi mphamvu, amagwiritsidwa ntchito ngati nsalu yophimba kutentha kwa kutentha kwapamwamba, chitetezo chosasunthika chamoto chothandizira kukonza zipangizo, kapena zipangizo zosavuta zomangira mapaipi otentha kwambiri. Imatha kupirira kutentha kwakanthawi kochepa ndipo ndiyosavuta kuyiyika, kuonetsetsa chitetezo chantchito.
