Mokhoa oa ho ntlafatsa khanyetso ea meokho ea masela a nonwoven a spunbond?

Ehlile. Ho ntlafatsa ho hanyetsa ha meokho ea masela a sa roaloang a spunbond ke projeke e hlophisehileng e kenyelletsang ntlafatso ea likarolo tse ngata, ho tloha ho lisebelisoa tse tala le lits'ebetso tsa tlhahiso ho fihlela qetellong. Ho hanyetsa meokho ho bohlokoa bakeng sa ts'ebetso ea ts'ireletso joalo ka liaparo tse sireletsang, kaha li amana ka kotloloho le ho tšoarella ha thepa le polokeho ha e huloa ka phoso le ho hojoa.

E latelang ke mekhoa ea mantlha ea ho ntlafatsa ho hanyetsa ho taboha ha masela a nonwoven a spunbond:

Ntlafatso ea Lintho tse tala: Ho Aha Motheo o Matla

Ho khetha li-polymers tse thata haholo:

Boima bo Phahameng ba Molek'hule / Phatlalatso ea Boima ba Limolek'hule Polypropylene: Ketane e telele ea molek'hule le ho ferekanngoa ho hoholo ho fella ka matla a holimo le ho tiea.

Copolymerization kapa Phetoho ea ho Kopanya: Ho eketsa palo e nyane ea polyethylene kapa li-elastomer tse ling ho polypropylene. Kenyelletso ea PE e ka fetola boits'oaro ba kristale ea thepa, ea ntlafatsa ho tenyetseha le ho hanyetsa tšusumetso, ka tsela eo e ntlafatsa ho hanyetsa meokho.

Eketsa Liphetoho tsa Liphello: Ho hlahisa li-elastomer tse khethehileng kapa mekhahlelo ea rabara kaha lintlha tsa khatello ea maikutlo li ka monya le ho hasanya matla a likhapha, ho thibela ho ata ha crack.

Ho sebelisa li-Fiber tse sebetsang hantle haholo:

PET leLikarolo tsa PP: Ho hlahisa likhoele tsa polyester nakong ea ts'ebetso ea spunbonding. PET, ka modulus ea eona e phahameng le matla, e tlatsana le likhoele tsa PP, e matlafatsang matla a kakaretso a marang-rang a fiber.

Ho sebelisa likhoele tsa bicomponent, joalo ka "mofuta oa sehlekehleke" kapa "core-sheath" meaho. Ka mohlala, ho sebelisa PET e le "core" bakeng sa matla le PP e le "sheath" bakeng sa ho khomarela mocheso, ho kopanya melemo ea bobeli.

Taolo ea Ts'ebetso ea Tlhahiso: Ho ntlafatsa Sebopeho sa Fiber Network

Ena ke mohato oa bohlokoa ka ho fetisisa oa ho ntlafatsa khanyetso ea meokho.

Mekhoa ea ho ohla le ho taka:

Ho Ntlafatsa Matla a Fiber: Ho ntlafatsa lebelo la ho taka le mocheso ho lumella hore ho be le mokhoa o feletseng le crystallization ea macromolecules ea polymer, e leng se hlahisang matla a phahameng, a phahameng-modulus monofilament fibers. Li-monofilaments tse matla ke motheo oa masela a matla.

Ho Laola Fiber Fineness: Ha ho ntse ho netefatsa botsitso ba tlhahiso, ho fokotsa ka mokhoa o nepahetseng bophara ba fiber ho eketsa palo ea likhoele sebakeng se seng le se seng, ho etsa hore marang-rang a marang-rang a be matla le ho lumella ho ajoa ha mojaro hamolemo tlas'a khatello ea maikutlo.

Mekhoa ea ho Theha le ho Matlafatsa Websaete:

Ho ntlafatsa Fiber Orientation Randomness: Ho qoba ho lumellana ho feteletseng ha fiber ea unidirectional. Ho ntlafatsa theknoloji ea ho etsa marang-rang ea moea ho theha marang-rang a isotropic fiber. Ka tsela ena, ho sa natsoe tataiso ea matla a haholang, palo e kholo ea likhoele tse tšekaletseng e e hanela, e leng se etsang hore ho be le khanyetso e phahameng ea ho lla.

Optimized Hot Rolling Process:

Bond Point Design: Ho sebelisa mokhoa oa "matheba a manyane a pakiloeng" Lintlha tse nyane, tse teteaneng tsa bond li tiisa matla a lekaneng a tlamahano ntle le ho senya ts'ebetso ea fiber ka mokhoa o feteletseng, ka katleho ho qhala khatello ea kelello ka har'a marang-rang a maholoanyane le ho qoba khatello ea kelello.

Mocheso le Khatello: Ho laola hantle mocheso o chesang oa mocheso le khatello ho tiisa ho kopana ka ho feletseng ha likhoele libakeng tsa bond ntle le khatello e feteletseng e ka senyang kapa ea senya likhoele ka botsona.

Matlafatso ea Hydroentangling: Bakeng sa lisebelisoa tse itseng, hydroentangling e sebelisoa e le mokhoa o mong kapa oa tlatsetso ho theolelo e chesang. Ho jella ha metsi ka khatello e phahameng ho etsa hore likhoele li koalehe, 'me li etse sebopeho se hokahaneng se nang le mahlakore a mararo. Sebopeho sena se atisa ho sebetsa hantle ka ho hanyetsa meokho 'me se fella ka sehlahisoa se bonolo.

Theknoloji ea ho Qetela le e Kopantsoeng: Ho Hlahisa Matlafatso ea Kantle

Lamination / Composite Technology:

Ena ke e 'ngoe ea mekhoa e tobileng le e sebetsang ka ho fetisisa. Lesela le sa lohoeng la Spunbond le entsoe ka khoele, lesela le lohiloeng, kapa lesela le leng la lesela la spunbond le nang le sebopeho se fapaneng.

Molao-motheo: Likhoele tse matla a phahameng ka har'a letlooeng kapa lesela le lohiloeng li etsa skeleton ea macroscopic e matlafatsang e sitisang haholo ho ata. Sena ke hantle sebopeho se atisang ho sebelisoa liphahlong tse phahameng tsa tšireletso, moo khanyetso ea ho taboha e tsoang ka ntle ho lera e matlafatsang.

Qetello ea ho Impregnation:

Lesela la spunbond le kenngoe ka emulsion ea polymer e loketseng ebe e phekoleha mateanong a fiber. Sena se eketsa haholo matla a maqhama lipakeng tsa likhoele, ka tsela eo, se ntlafatsa matla a ho tabola, empa se ka tela bonolo le ho hema.

Kakaretso le Lintlha tsa Bohlokoa

Ho ntlafatsa ho hanyetsa ho taboha ha masela a sa lohiloeng a spunbond, hangata ho hlokahala mokhoa o nang le mefuta e mengata:

Boemo | Mokhoa | Karolo ea mantlha

Lisebelisoa tse tala | Sebelisa li-polymers tse thata haholo, phetoho ea motsoako, eketsa li-elastomer | Ntlafatsa matla le katoloso ea likhoele tsa motho ka mong

Mokhoa oa Tlhahiso | Ntlafatsa ho ngola, theha isotropic fiber webs, ntlafatsa hot rolling / hydroenangling process | Theha sebopeho sa marang-rang se matla, se ts'oanang sa fiber se nang le khatello e ntle ea khatello ea maikutlo

Ho qetela | Laminate ka likhoele, impregnate | Hlahisa mekhoa ea ho matlafatsa ka ntle ho thibela ho taboha

Sepheo sa mantlha ha se feela ho etsa hore fiber e 'ngoe le e' ngoe e be matla, empa hape ho etsa bonnete ba hore mohaho oohle oa marang-rang oa fiber o ka qhalakanya ka katleho le ho monya matla ha o tobane le matla a ho qhaqha, ho e-na le ho lumella khatello ea kelello hore e tsepamise maikutlo le ho hasana ka potlako sebakeng se le seng.

Tlhahisong ea 'nete, motsoako o loketseng ka ho fetisisa o lokela ho khethoa ho ipapisitse le tšebeliso ea sehlahisoa, tekanyetso ea litšenyehelo, le tekanyo ea ts'ebetso (joalo ka ho kenella ha moea le bonolo). Ka mohlala, bakeng sa ts'ebetso e phahameng ea liaparo tse sireletsang lik'hemik'hale tse kotsi, sebopeho sa sandwich se kopantsoeng sa "lesela le nang le matla a phahameng a spunbond + filimi e phahameng-barrier + mesh reinforcement layer" ke tekanyo ea khauta ea ho finyella ka nako e le 'ngoe ho hanyetsa ho lla, ho hanyetsa ho phunya le ho sireletsa lik'hemik'hale.
