Spunlace nonwoven ye pre-oxygenated fiber
Segment market:
Hunhu hwePre-Oxygenated Fiber:
· Ultimate Flame Retardancy: Muganho weokisijeni index (LOI) kazhinji > 40 (chikamu cheokisijeni mumhepo chingangoita 21%), chinopfuura kupfuura chemazuva ese anogara achidzora murazvo (senge polyester inodzora murazvo ine LOI ingangoita 28-32). Hainyunguduki kana kudonha kana yaiswa pamoto, inodzima pachayo mushure mekubvisa moto, uye inoburitsa hutsi hushoma uye haina magasi ane chepfu panguva yekupisa.
· Yakakwira-Tembiricha Kugadzikana: Iyo tembiricha yenguva refu yekushandiswa inogona kusvika 200-250 ℃, uye yenguva pfupi inogona kumira 300-400 ℃ yakanyanya tembiricha (kunyanya zvichienderana neyakagadzirwa uye pre-oxidation degree). Iyo ichiri kuchengetedza kutendeseka kwechimiro uye mechanical properties munzvimbo dzepamusoro-tembiricha.
· Chemical Resistance: Ine kumwe kuramba kune acids, alkalis, uye organic solvents, uye haisi nyore kunyungudika nemakemikari zvinhu, yakakodzera kushandiswa munzvimbo dzakaoma.
· Zvimwe Mechanical Properties: Iine kumwe kusimba uye kusimba, uye inogona kugadzirwa kuita zvinhu zvine chimiro chakatsiga kuburikidza neasina kuruka machira ekugadzira machira (akadai sekubaya tsono, spunlace).
II. Kugadzira Technology yePre-Oxygenated Nonwoven Fabrics
Pre-oxygenated fiber inoda kugadziriswa kuti irambe ichiita pepa-semidziyo kuburikidza nemaitiro ekugadzira machira asina kuruka. Maitiro akajairika anosanganisira:
· Nzira yekubaya tsono: Nekuramba uchibaya fiber mesh netsono dzemuchina wetsono-punch, fiber inopindirana uye inosimbisana, ichigadzira jira risina kuruka rine humwe hukobvu uye simba. Iyi nzira yakakodzera kugadzira micheka yakakwirira-yakasimba pre-oxygenated fiberless, iyo inogona kushandiswa mumamiriro ezvinhu anoda kutsigirwa kwemaitiro (zvakadai semapuranga asingasviki moto, kupisa kwepamusoro-kupisa zvinhu).
·Spunlaced Method: Kushandisa high-pressure water jets kukanganisa fiber mesh, mafiibhi anopindirana uye anobatana. Iyo spunlaced pre-oxygenated jira ine yakapfava kunzwa uye zviri nani kufema, uye inokodzera kushandiswa mukati memukati yezvipfeko zvekudzivirira, inochinjika inodzivirira moto padding, nezvimwe.
· Thermal Bonding / Chemical Bonding: Nekushandisa yakaderera-yakanyungudika-point fiber (senge flame-retardant polyester) kana zvinonamira kubatsira mukusimbisa, kuomarara kweyakachena pre-oxygenated fiberless jira inogona kuderedzwa, uye mashandiro ekugadzirisa anogona kuvandudzwa (asi cherechedza kuti kupisa kwekushisa kweiyo inonamira kunoda kuenderana ne pre-oxygen nharaunda yekushandisa).
Mukugadzirwa chaiko, pre-oxidized fibers inowanzosanganiswa nemamwe mafiber (akadai searamid, flame-retardant viscose, girazi fiber) kuenzanisa mutengo, kunzwa uye kuita (somuenzaniso, yakachena pre-oxidized isiri-yakarukwa jira rakaoma, asi kuwedzera 10-30% murazvo-retardant viscose inogona kuvandudza kupfava kwayo).
III. Yakananga mashandisirwo emamiriro e pre-oxidized fiber isiri-yakarukwa jira
Nekuda kweiyo inodzoreredza murazvo uye yakakwirira-tembiricha inodzivirira zvivakwa, pre-oxidized fiber isina-yakarukwa jira rinoita basa rakakosha muminda yakawanda:
1. Kudzima moto uye kuchengetedzwa kwemunhu
· Firefighter's internal lining / outer layer: Pre-oxidized non-woven fabric is flame-retardant, high-temperature inopikisa uye inofema, uye inogona kushandiswa seyakakosha yezvipfeko zvekudzima moto kudzivirira kuendeswa kwemoto uye kupisa kwakanyanya, kudzivirira ganda revanodzima moto; kana yakasanganiswa nearamid, inogonawo kuvandudza kusakara uye kuramba kubvarura.
· Welding / metallurgical protective equipment: Inoshandiswa kugadzira maski linings, magirovhosi asingadziviriri kupisa, maapuroni evashandi vesimbi, zvichingodaro, kurwisa mazhenje anobhururuka uye nemwaranzi yekushisa kwepamusoro (ine tembiricha yenguva pfupi inopfuura 300 ° C).
· Zvekupukunyuka zvechimbichimbi: Zvakadai semagumbeze emoto, masifa esefa zvinhu, zvinogona kuputira muviri kana kusefa utsi panguva yemoto (utsi hushoma uye husina chepfu zvakanyanya kukosha).
2. Indasitiri yakakwirira-yekudzivirira yekudzivirira uye kuvhara
· Industrial insulation zvinhu: Inoshandiswa semukati wepakati-yepamusoro-tembiricha pombi, boiler insulation pads, nezvimwewo, kuderedza kupisa kurasikirwa kana kutamisa (kureba kupikisa kusvika 200 ° C uye pamusoro penzvimbo).
· Zvishandiso zvekuvaka zvisingadzivirirwe nemoto: Seyekuzadza machira emaketeni asina moto uye madziro emoto muzvivakwa zvepamusoro-soro, kana tambo yekuvharisa zvinhu, kunonoka kupararira kwemoto (kusangana neiyo GB 8624 yekudzivirira moto giredhi B1 uye pamusoro pezvinodiwa).
· Kudzivirirwa kwemidziyo yemhando yepamusoro-yepamusoro: Semaketeni ehovhoni, mavhavha ekudzivirira kupisa kwehovhoni nehovhoni, kudzivirira vashandi kubva pakupiswa nepamusoro-soro pamusoro pemidziyo.
3. High-temperature filtration fields
· Kusefeta gasi remumaindasitiri: Tembiricha yegasi rinopfungaira rinobva kune zvinopisa tsvina, zvigayo zvesimbi, mavira emakemikari anoita zvinowanzosvika 200-300°C, uye ine magasi ane acidic. Pre-oxidized isiri-yakarukwa jira rinoshingirira kune yakakwira tembiricha uye ngura, uye inogona kushandiswa seyakadzika zvinhu zvemabhegi esefa kana masilinda esefa, inonyatso kusefa.
4. Zvimwe zviitiko zvakakosha
Zvishandiso zvemuchadenga zvekubatsira: zvinoshandiswa sematanho ekudzivirira moto mukati memakabhini ezvitundumuseremusere uye magasi ekutambisa kupisa akatenderedza mainjini ezvitundumuseremusere (ayo anoda kusimbiswa neresin inodzivirira kutonhora kwepamusoro).
Magetsi insulating zvinhu: Inoshandiswa se insulating gaskets mune yakakwirira-tembiricha motors uye transformer, anogona kutsiva echinyakare asbestos zvinhu (asina-carcinogenic uye zvakawanda zvakatipoteredza hushamwari).
Iv. Zvakanakira uye Mafambiro Ekusimudzira ePre-Oxidized fiber Nonwoven Fabrics
Zvakanakira: Zvichienzaniswa nemidziyo yechinyakare inodzoreredza moto (seasbestos negirazi faibha), pre-oxygenated faibha isiri-yakarukwa jira harina kenza uye rinogoneka zviri nani. Kana ichienzaniswa nemafuta akakwira-mutengo senge aramid, ine mutengo wakaderera (inenge 1/3 kusvika 1/2 yearamid) uye inokodzera batch application mune yepakati uye yepamusoro-yekupedzisira-inodzoreredza murazvo.
Mafambiro: Kuvandudza compactness uye kusefa kushanda zvakanaka kwemachira asina kurukwa kuburikidza nefiber refinement (yakadai sefine denier pre-oxygenated filaments, diameter <10μm); Gadzira maitiro ekugadzirisa zvakatipoteredza ane yakaderera formaldehyde uye isina anonamatira; Yakasanganiswa nemananomaterials (senge graphene), inowedzera kukwirisa-tembiricha kuramba uye antibacterial zvinhu.
Mukupedzisa, kushandiswa kwe pre-oxidized fibers mumachira asina kurukwa kunonamira pazvimiro zvadzo zve "flame retardancy uye high-temperature resistance" kugadzirisa kusakwana kwekuita kwezvinhu zvechinyakare mukupisa kwepamusoro uye kuvhurika kwemoto. Mune ramangwana, nekuvandudzwa kwekuchengetedzwa kwemaindasitiri uye mitemo yekudzivirira moto, maitiro avo ekushandisa achawedzerwa.
