1,Lub hauv paus ntsiab lus ntawm cov tseem ceeb ua haujlwm
Anti UV Polyester Dope Filament Filament Filovent Filovent Fileent Herpenty Kev Tiv Thaiv UV (UV-A / UV-B) rau hauv hluav taws xob thermal lossis qis-hluav taws xob hluav taws xob. Kev sib xyaw ntawm Dyeing thiab anti UV Liaj Ua Haujlwm yuav tsum tau sib npaug kev ruaj ntseg thiab sib xyaw ntawm ob qho tib si.
2,Cov ncauj lus kom ntxaws piav qhia ntawm cov txheej txheem tseem ceeb
(1)Raw khoom pretreatment thiab hloov kho
Xaiv UV nqus
Yuav tsum tau: Particle Loj ≤ 1 μ m (kom tsis txhob muaj kev thaiv kiv), thermal ruaj khov rau polyester (kom tiv thaiv nag lossis daus).
Ntaus:
Organic me me molecule kev ua tiav (xws li UV-531): Qhia los ntawm cov paj lug sib xyaw, nrog cov nthwv dej nqus ntawm 290-400nm.
Nano inorgine fwj (xws li tio ₂, zno): Nrog ib qho me me ntawm 50-100nm, txhim kho kev tiv thaiv los ntawm kev tiv thaiv ulteriolet teeb, thiab yuav tsum tau kho kom muaj regupling reflepling tus neeg sawv cev tus neeg sawv cev.
Kev npaj ntawm polyester sib
Kev Hloov Kho Kev Hloov: Lub sijhawm Polyester Melt polymerization (lossis tom qab lub xeev-lub xeev polymerization), UV
Kev Hloov Kho Polymerization: Monomers muaj UV nqus pawg (xws li Benzotriazole p-hydroester molecyate) tau koom nrog cov khoom lag luam polyester (siab ntev, haum rau cov khoom lag luam siab).
(2)Spinning thiab ncab txheej txheem
Spinning parameter tswj
Qho so: Melt Spinning kub yog 285-300 ℃ (5-10 ℃ siab dua li dog dig polyester) kom tsis txhob decomposition lossis agglomeration ntawm kev nqus.
Hov ceev: Kev kub ceev spinning (4000-5000 m / min) ua ke nrog nplua denier (15-50 dtex) kom nce cov txiaj ntsig nto deg thiab txhim kho UV thaiv cov nyhwv.
Ncab thiab Shaping Ua Kom Zoo
Ncab piv: 3.5-4.0 zaug, txhim kho frystallinity (crystallinity ≥ 45%), txo cov kev tsis zoo, thiab zam dhau UV nkag.
Tshav kub kub teeb tau kub: 180-200 ℃ (10-20 ℃ qis dua li dog dig polyester), los tiv thaiv cov dermal decomposition ntawm nqus thiab tswj shrinkage tus nqi ≤ 8%.
(3)Dyeing txheej txheem (tseem ceeb compatibility tswj)
Xaiv Kev Dyeing Txoj Kev
Cov kua ua kua rau + UV REIGNANT CRENDING: Ua ntej Spinning Masterbatch thiab UV AbsorBatch thiab UV AbsorBER tau ntxiv ib txhij, haum rau cov khoom tsaus (xim xiav, thiab lwm yam 4 thiab ntev ntev kev tiv thaiv UV.
Post Staining + Anti UV Xov:
Yuav tsum tau siv cov kev ntsuas kub siab thiab muaj kev sib cav sib ceg
Tom qab dye zas xim, di ncauj dov ultraviolet xaus tus neeg sawv cev (xws li dej tsis zoo yog tsis zoo (feem ntau yog UP cov nqi txo los ntawm 20% tom qab 5 zaug ntawm kev ntxuav).
Kev ua kom zoo ntawm cov txheej txheem zas xim
Txom Nyem: PHIC PH HMOOV DY DA YOG 4.5-5.Qhov tsis muaj zog acidic) los tiv thaiv kev nqus dej ntawm cov mob benzaline (xws li Benzopenones yooj yim hauv ph> 7).
Ntxiv Xaiv: Ntxiv cov neeg sawv cev tsis-ionic (xws li roj cawv polyoxythylene ether) kom zam dhau qhov rov ua dua tshiab ntawm ionic ntxiv thiab nqus tau, uas tuaj yeem cuam tshuam kev tawg.
(4)Ua haum rau synergy tswj
Kev sib cuam tshuam ntawm kev nqus tau thiab zas
UV nqus tau yuav muaj kev sib tw nrog cov neeg tuag rau cov chaw khi rau ntawm qhov tob (K / S tus nqi txo los ntawm kev zas xim ntxiv lossis ua kom zoo rau cov mis.
Piv txwv li, thaum tawg kom tob, tus nqi ntawm doger polyester zas yuav tsum tau nce ntxiv rau 2.5% -3% (OWF).
Improved light fastness
UV tej kev nqus tuaj yeem pab txhim kho lub teeb nrawm ntawm kev ua kom muaj kev puas tsuaj loj dua ntawm qib UV 60), raws li kev ua kom muaj kev puas tsuaj rau UV Rays kom zas molecules.
3,Cov kev sib txawv thiab cov kev daws teeb meem
Tsis zoo tawg ntawm kev nqus
Teeb meem: Agglomeration ua rau spinning breakage thiab txo lub zog muaj zog.
Lus teb: Txais cov nano sib tsoo thev naus laus zis (sib tsoo nrog cov xuab zeb nrog rau d50 ≤ 500nm) + deg kev hloov kho (xws li txheej tio ₂ nrog stearic acid).
Cov khaub ncaws tsis txaus ntawm staining
Teeb meem: Absorbents cuam tshuam rau qhov dyeing tus nqi ntawm dyes, ua rau kev sib deev.
Cov txheej txheem: Segensed cua sov thiab dyeing (xws li cua sov ntawm 1 ℃ / min rau 30-60 ℃ thiab 2- min rau 60-130 ℃), txuas ntxiv lub sijhawm rwb thaiv tsev rau 40 feeb.
Ua kom ruaj khov
Teeb meem: Kev ntxuav tsis zoo ntawm anti UV cov neeg sawv cev tom qab ua tiav.
Lus teb: Resove Absorbents (xws li UV
4,Daim Ntawv Thov Kev Ua Yeeb Yam thiab cov txheej txheem kev yoog
Sab nraum zoov khaub ncawsYuav tsum muab cov txheej txheem ntawm cov xim ua ntej nrog cov kev daws teeb meem qub thiab kev sib xyaw ua ke UV kev tiv thaiv thiab cov khaub ncaws hnav zoo nkauj thiab cov khaub ncaws tiv thaiv hnub).
Sab Hauv Tsev Kho Kom Zoo Nkauj: Tso cai ua tiav los anti UV + cov txheej txheem dowing cov txheej txheem, xws li cov nqi qis (xws li cov ntaub, sunshades), tab sis yuav tsum muaj kev tu plaub hau.
Cov Khoom Siv Kho Mob: Co hloov kho thiab thawj cov kua xim kom tsis txhob muaj kev tsiv teb tsaws (xws li kev phais mob khaub ncaws hnav thiab cov ntaub qhwv), ua raws li kev nyab xeeb cov qauv kev nyab xeeb.
