Lub cev thiab tshuaj
Cov khoom xyaw: Cov khoom xyaw tseem ceeb yog diacetate diacetate lossis cellulose triacetate.
Zog: dawb los yog lub teeb daj fiber ntau bunds nrog ib tug siter luster.
Qhov ceev faj: 1. {{{28-1. 32 g / cm³ los yog hnyav dua li hluavtaws hluavtaws.
Melting taw tes: Txog {230-300 degree (decomposition kub).
Hygroscopicity: kev nqus dej noo kev nqus yog txog 6-7%, uas yog qis dua paj rwb fiber tab sis siab dua li Polyester Fiber.
Cov Khoom Siv Neeg Kho Tshuab
Lub zog: lub zog qhuav yog li 1. {2-1. 5 g / denier yog me ntsis txo.
Txiaj: elongation thaum tawg yog hais txog 20-30%, nrog qee yam nyuaj.
Puas Ua Ntej: Nruab nrab, haum rau kev siv lim tab sis tsis haum rau kev sib txhuam siab.
Cov yam ntxwv ua haujlwm
Kev lim dej: Cov qauv fiber ntau tuaj yeem ua tau zoo nqus cov tshuaj uas muaj teeb meem xws li tar thiab nicotine.
ThermoplasticS: Lub lim tuaj yeem tsim los ntawm cua sov los txhim kho lub hardness thiab ruaj khov ntawm lub lim.
Ntsis: Nws tuaj yeem yog qee qhov biodegraded nyob rau hauv lub ntuj ib puag ncig thiab yog ib puag ncig ntau dua li cov khoom siv hluavtaws ntshiab.
Cov txheej txheem ntau lawm
Raw Khoom Npaj
Siv cov ntoo siab huv pulp los yog cov paj rwb ligners raws li lub cellulose qhov chaw.
Tom qab tshuaj dawb, ziab thiab lwm yam kev ua ntej, ua kom cov purity ntawm cov ntaub ntawv raw
01
Acetylation cov tshuaj tiv thaiv
Cellulose reacts nrog acetic anhydride nyob rau hauv muaj ntawm catalyst (xws li sulfuric acid) los tsim cov acetate cellulose.
Cov kev mob tshwm sim: kub 30-50 degree, sijhawm ntau teev.
02
Kev tshem tawm thiab kev lim
Dissolve cellulose acetate hauv cov kuab tshuaj yeeb yaj kiab xws li acetone los ua cov tshuaj spinning.
Lim kom tshem tawm impurities thiab xyuas kom meej tias kev daws teeb meem spinning yog cov khaub ncaws.
03
Caws moulding
Cov txheej txheem tig qhuav (cov txheej txheem cattream yog extruded los ntawm cov spinneret, thiab huab cua kub yaj rau daim ntawv txuas ntxiv.
Ntub dej spinning: tsawg siv, haum rau cov khoom lag luam nrog cov tshwj xeeb tshwj xeeb.
04
Kev Ua Haujlwm Tom Qab
Cov pob roj fiber yog ntxuav, ncab, curled, qhuav thiab lwm cov txheej txheem los txhim kho lawv cov khoom siv thiab kev sib txuam.
Cov khoom kawg yog txiav thiab ntim raws li cov lus qhia tshwj xeeb
05
Kev Loj Hlob Qauv
Ib puag ncig phooj ywg acetate fiber ntau: Tsim cov khoom lag luam nrog cov kuab tshuaj qis dua thiab siab dua biodegradity.
Hloov cov ntoo tsoos: Tshawb nrhiav cov ntawv thov hauv cov ntawv ntim thiab cov ntaub tsis-ntaub.
Kev Txhim Kho Kev Ua Haujlwm: TUGCEATION SATION xws li cov tshuaj tiv thaiv kab mob thiab cov tshuaj tua kab mob.
Chaw thov
Cov Ntxaij Teb Lim (Application Ntsiab)
Txog 90% ntawm lub ntiaj teb acetate fiber ntau cab yog siv nyob rau hauv cov tshuab luam yeeb.
Cov txiaj ntsig: Adsorption Zoo, Muag Saj, Kev Ua Tau yooj yim
01
Textile Kev Lag Luam Textile
Siv los ua cov kab ntawv siab kawg, ris tsho hauv qab, kab tshoob kev hnav, thiab lwm yam, nrog lo lo ntxhuav zoo li no thiab xis nyob
02
Cov ntaub ntawv kho mob
Siv raws li kev phais mob, hnav khaub ncaws, thiab lwm yam vim lawv txoj kev zoo biocompatibility.
03
Muaj lim cov ntaub ntawv, tsis-woven cov ntaub rau cov tshuaj pleev ib ce, thiab lwm yam.
