Pulp purity yog hais txog qib ntawm cellulose cov ntsiab lus thiab tus nqi ntawm impurities nyob rau hauv lub pulp. Qhov zoo tshaj plaws pulp yuav tsum nplua nuj nyob rau hauv cellulose, thaum cov ntsiab lus ntawm hemicellulose, lignin, tshauv, extractives thiab lwm yam uas tsis yog-cellulose Cheebtsam yuav tsum tsawg li tsawg tau. Cov ntsiab lus ntawm cellulose ncaj qha txiav txim siab purity thiab usability tus nqi ntawm lub pulp, thiab yog ib qho ntawm cov tseem ceeb qhia rau kev ntsuam xyuas pulp zoo. Cov yam ntxwv ntawm siab purity pulp:
(1) ntau dua durability, cellulose yog lub ntsiab tivthaiv uas tsim lub zog ntawm daim ntawv, siab purity pulp txhais tau hais tias ntau dua cellulose cov ntsiab lus, yog li daim ntawv tsim muaj zog tsim kua muag kuj, folding kuj thiab lwm yam lub cev thiab txhua yam khoom, ncua kev pab cuam lub neej ntawm lub ntawv.
(2) Kev sib koom ua ke muaj zog dua, cov ntshiab cellulose fibers tuaj yeem tsim qhov sib txuas sib txuas ntawm cov ntawv los txhim kho cov kev sib txuas sab hauv, kom cov ntawv tsis yooj yim rau delaminated lossis tawg thaum raug rau sab nraud, txhawm rau txhim kho tag nrho lub zog ntawm daim ntawv. .
(3) siab dua whiteness, muaj impurities feem ntau cuam tshuam rau cov dawb thiab gloss ntawm daim ntawv. High purity pulp, vim yog tshem tawm ntawm feem ntau ntawm cov xim impurities, ua rau daim ntawv qhia ib tug ntau dua natural whiteness, uas yog ntau haum rau luam ntawv, sau ntawv thiab ntim, thiab lwm yam, thiab txhim khu kev pom kev ntawm cov khoom.
(4) cov khoom siv hluav taws xob zoo dua qub, cellulose muaj cov khoom siv hluav taws xob zoo, thaum cov khoom tsis yog cellulose hauv cov ntaub so ntswg, xws li lignin, yuav muaj cov khoom siv hluav taws xob lossis hygroscopic, cuam tshuam rau hluav taws xob rwb thaiv tsev ntawm daim ntawv. Yog li ntawd, daim ntawv ua los ntawm high-purity pulp muaj ntau yam kev siv nyob rau hauv hluav taws xob engineering, xws li cable rwb thaiv tsev ntawv, capacitor ntawv, thiab lwm yam.
Kev npaj siab purity pulp, kev lag luam ntawv niaj hnub siv ntau yam txheej txheem pulping, xws li tshuaj pulping (xws li sulphate pulping, sulphite pulping, thiab lwm yam), mechanical pulping (xws li thermal sib tsoo txhua yam pulp TMP) thiab chemical mechanical pulping (CMP). ) thiab lwm yam. Cov txheej txheem no txhim kho cov purity ntawm cov nqaij mos los ntawm kev tshem tawm lossis hloov cov khoom tsis-cellulosic ntawm cov khoom siv raw.
High purity pulp yog dav siv nyob rau hauv ntau lub teb xws li high-qib kab lis kev cai ntawv, ntim ntawv, ntawv tshwj xeeb (xws li, hluav taws xob rwb thaiv tsev ntawv, lim ntawv, ntawv kho mob, thiab lwm yam) thiab tsev neeg ntawv, uas ua tau raws li cov txheej txheem siab ntawm daim ntawv zoo. xav tau los ntawm kev lag luam sib txawv.
Yashi Ntawv tsuas yog ua 100% nkauj xwb xyoob pulp, ib qho ci xyoob fiber ntau, uas yog qhov kev xaiv zoo tshaj plaws rau siab purity thiab cov ntawv zoo hauv tsev.
