Cov kws ua lag luam hauv domestic uas yog ib qho chaw zoo nkauj zoo li UV cov phom sij thiab cov khoom zoo rau tus kheej UV varnish yog: Huaqing (Guangzhou) Group, thiab lwm yam., Vim hais tias cov khoom siv li sau ua kua dej-soluble, thiab qhov thib ob yog toluene diisocyanate uas tsis muaj carcinogens. Qhov peb cov duab tsis yog tshuaj lom neeg yog li ntawd nyiam los ntawm lub ntim thiab luam ntawv kev lag luam.
15. Puas muaj ib lub tuam txhab ua hluav taws xob uas muaj cov dej kub high-raws li cov kua txaig tawv?
Yog, nws yog koom tes ntawm Jingang Technology (International) Group: Fuding City, Fujian Province, Jingang Polymer Materials Co., Ltd. Xim no yog xaiv los ntawm PUL-1 resin raws li tus lej phau ntawv.
16. Cov txheej txheem twg muaj nyob rau hauv txoj kev kuaj pom kev luam ntawv lej zoo?
(1) xim; (2) lub zog lub zog; (3) fineness; (4) fluidity; (5) kev ruaj ntseg; (6) viscosity; (7) viscosity nce; (8) ya number case; Gloss; (10) kev nce ceev; (11) txhuam; (12) conjunctival drying; (13) osmotic ziab; (14) tshuaj lom neeg ua rau tsis muaj ethanol; (15) ntshav; (16) acid nqi ntawm cov roj; 17) xim; (18) number case yam ntxwv kab; (19) cuam tshuam; (20) ndlwg nqis (qhov txhab ntxiv); (21) zaj duab xis nyuaj; (22) viscosity; (23) qhuav; (24) Ntu Tension; (25) hnyav ntxiv; (26) dryness; (27) pH; (28) dej tsis haum; (29) tshem tawm hauj lwm thiab lwm yam kev cai 29 lub teb chaws.
17. Ua li cas thiaj li muaj xim xaum xim los yog muaj txoj hlab tom qab tha xim, xa me nyuam rov qab los sis tsis ua kom tiav (thiab khiav hauj lwm qhov kev tua cov hniav)?
Tom qab cov khoom siv luam yeeb los ntawm cov tshuab luam yeeb los yog npog aluminium hlab ntawv saum toj kawg nkaus, vim yog qhov ntau ntawm cov tawv tawv ntau hauv cov xauv kua los yog ntau ntxiv ntawm kev pabcuam theem qis thiab cov nplaum uas siv los tiv thaiv cov qos, nws feem ntau tsis yog vim cov tawv nqaij tawv ntawm cov ntawv luam tawm ua duab xis. Yog hais tias qhov chaw muaj zog heev los yog cov kua roj hmab dhau lawm, tus qub yuav pom tshwm thiab ua poob tom qab txiav, thiab tom kawg yuav nyuaj rau kev txiav thiab thaiv, ua rau muaj kev nce nqi. Qhov thib ob, cov duab mos qhov muag (tshwj xeeb yog cov ntxhib ntxhib ntxoo qhov muag uas tsis tshua muaj me me) yog ntub hauv cov cwj mem kob hauv cov duab los yog cov roj zaj duab xis thaum lub sij hawm luam ntawv, thiab feem ntau nyuaj rau kev txiav cov khoom luam tawm tom qab luam ntawv, tshwj xeeb tshaj yog thaum txiav . Pov thaiv, hauv daim ntawv ntawm kev qhia: nyuaj rau ua txhaum, txiav, feem ntau ua rau raug mob riam los yog tuag ntuag. Thaum cov neeg kho vajtse high-speed labeling, nws nyuab nyhav rau adsorb ncej, ua rau kev txo qis rau cov neeg kho vajtse labeling tus nqi. Peb tuaj yeem ntsuam xyuas qhov sib piv raws li cov qauv sib txawv, thiab sau cov txheej txheem kev txhim kho kev txhim kho kom pab kho.
18. Yuav ua li cas yuav ua li cas nrog lub deformation ntawm daim pam thiab lub siab zoo letterpress?
Kev nthuav dav ntawm daim pam lossis yoog tau yooj yim yog tshwm sim los ntawm kev siv cov ntawv luam tawm cov phaj nyaj uas muaj qee cov resins los yog cov kuab tshuaj muaj zog. Txoj kev kho mob li ib txwm yog: (1) kev hloov ntawm tus number case uas tsis muaj teeb meem; (2) tshem daim pam nrog ib qho tshuaj tiv thaiv oxidizing, los yog kev kho lub pam nrog ib hom tshuaj kua faj siv ua ntej siv.
19. Kuv yuav tsum ua li cas yog tias muaj ib daim kab xev xev thaij duab tom qab tus number case yog luam tawm?
Vim lub zog tsis zoo ntawm cov menyuam thiab cov ntawv xov xwm (ib qho yog qhov teeb meem ntawm tus menyuam, thiab qhov thib ob yog cov pluag dispersion ntawm lub cev hauv cov xauv kua xau), tus number case yog siv rau ntawm ntug ntawm daim phaj me ntsis streak. Kuj tseem muaj kev sib haum ntawm cov menyuam qhov kev sib tw, uas ua rau ntau tus cwj pwm uas tau raug thawb mus rau ib sab rau txoj kab ntawm kab. Qhov no yog los kho tus menyuam rau lub plawv. Yog hais tias qhov muag tsis pom nyob rau hauv cov xaim xoom cim uas tau piav qhia hauv qhov no tsis zoo, tus number case yuav tsis sawv ntsug. Nws tuaj yeem muab tshem tawm los ntawm kev ntxiv ib lub ncuav los yog ntxiv ib pob mos mos.
20. Ua li cas thiaj li yuav kho tau tus cwj mem luam ntawv kom ua tau zoo dua yog tias tsis tau poob siab?
Qhov kev thov no yog to taub. Qee feem ntawm cov khw muag khoom siv feem ntau siv ntau cov khoom siv ntxiv los mus ua kom cov dej ntub thiab zawm ntawm cov cwj pwm zaj duab xis, tab sis ntev li ntawm ntxiv mus nyhav rau hauv cov cwj mem kob kom poob lub teeb pom kev, txawm tias thaum cov khoom siv luam yeeb nyhav dhau los tsis yooj yim rau cov roj hmab, Tuav cov nplaum nplaum. Vim li no, thaum lub sij hawm qhov kev pab cuam ntawm Xiamen Yongshengxing, lub tuam txhab tau txais txoj hau kev ntxiv kev txuas tus neeg sawv cev, uas zoo tuaj ntxiv cov qauv ntawm cov ntawv luam tawm thiab qhov affinity nrog cov substrate. Qhov no hloov cov khoom ntawm interfacial ntawm lub polymer thiab cov xim muab phuam, uas yog kev txhim kho cov kev ua ntawm lub luam tawm ntawm cov ntawv luam tawm thiab kev txhim kho cov gloss ntawm tus cwj pwm zaj duab xis. Qhov tshuaj lom neeg tshuaj no siv qhov chaw tsim kom muaj Si-O-Si tshuaj, uas yog tus khub thiab tus substrate, uas yog lub hauv paus ntawm tus neeg saib xyuas sib txuas.
