Cov txheej txheem tseem ceeb ntawm sizing muaj xws li: sizing tus nqi, damping tus nqi, nias-tawm damping tus nqi, elongation, sizing li nce tus nqi, sizing elongation txo tus nqi, tag nrho cov khoom ntawm sizing kua, thiab lwm yam.
1, sizing tus nqi:
Tom qab sizing qhov hnyav qhuav ntawm warp yarn ntawm qhov hnyav qhuav ntawm thawj warp xov paj ua ntej sizing feem pua.
Sizing tus nqi (%)=qhuav luj ntawm pulp * 100% / qhuav qhov hnyav ntawm thawj warp yarns
Nyob rau hauv qhov tseeb zus tau tej cov sizing tus nqi fluctuations yuav tsum tau tswj ntawm ± 1% nyob rau hauv txoj cai. Sizing pass tus nqi yuav tsum ntau dua 95% yog qhov zoo.
2, noo noo rov qab tus nqi:
Sizing damping tus nqi yog feem pua ntawm cov dej ntsiab lus ntawm qhov hnyav ntawm qhov sizing.
Moisture rov qab tus nqi=(sizing ntub yuag - sizing qhuav hnyav) * 100% / sizing qhuav hnyav
Moisture rov qab tus nqi yog loj heev ua rau lub weaving qhib tsis meej, cov ya raws rov qab tus nqi me me dhau, yuav ua rau lub taub hau nkig, nyob rau hauv qhov tseeb ntau lawm, cov dej noo rov qab hloov pauv yuav tsum tsawg dua ± 0.5 %, qhov noo noo rov qab tus nqi yuav tsum tau mastered nyob rau hauv 90% ntawm qhov zoo tshaj plaws.
3, nias tawm ntawm dampness tus nqi:
Qhov hnyav ntawm cov dej uas muaj nyob rau hauv sizing yarn ua ntej nkag mus rau hauv chav qhuav tom qab lub sizing roller, qhov feem pua ntawm qhov hnyav qhuav ntawm sizing yarn.
4, elongation:
Warp yarn sizing yarn elongation of the original warp yarn length of the percentage.
Sizing elongation %=(sizing ntev - thawj qhov ntev ntawm cov xov paj warp) * 100% / qhov ntev ntawm cov xov paj warp
General sizing elongation mastered hauv 0.5-1.5% yog qhov tsim nyog.
5, sizing nce tus nqi:
Lub zog tawg ntawm cov xov paj sizing thiab lub zog tawg ntawm thawj cov xov paj ntawm qhov sib txawv ntawm lub zog tawg ntawm thawj cov xov paj ntawm feem pua ntawm lub zog tawg.
Sizing nce tus nqi ntawm %=(sizing tawg lub zog - lub zog tawg ntawm thawj cov xov paj) * 100% / lub zog tawg ntawm thawj cov xov paj
6, sizing xov paj elongation txo:
Sizing ua ntej tus thawj warp yarn ntawm qhov sib txawv ntawm qhov tawg elongation ntawm thawj cov xov paj tawg elongation ntawm feem pua.
Qhov loj ntawm qhov elongation txo tus nqi ntawm %=(qhov tawg elongation ntawm thawj cov xov paj - sizing qhov tawg elongation) * 100% / qhov tawg elongation ntawm thawj cov xov paj
7, tag nrho cov khoom ntawm lub pulp:
Pulp sib tov kawg ntawm qhov ntim ruaj khov, ruaj khov viscosity, ruaj khov kub tom qab tag nrho cov ntsiab lus ntawm cov tawv nqaij qhuav hauv slurry.
Tag nrho cov khib nyiab %=qhuav qhov hnyav ntawm cov tawv nqaij * 100% / (dej hnyav hauv cov tawv nqaij + qhuav qhov hnyav ntawm cov tawv nqaij)
8, thiab slurry muaj pes tsawg leeg:
Slurry muaj nyob rau hauv ntau yam slurry, raws li tus txheej txheem tsim piv sib xyaw rau hauv slurry. Xws li: dej, lub ntsiab slurry thiab auxiliary slurry peb qhov loj.
Main slurry: feem ntau yog nplaum.
Pab slurry: Txhawm rau ua kom qhov loj me tom qab cov xov paj zoo dua, kev ua haujlwm ntawm cov yeeb yaj kiab tsis zoo, sib xyaw nrog cov khoom siv slurry. Xws li: decomposition agents, lubricants, preservatives, penetrating agents, defoamers, antistatic agents, softeners, hygroscopic agents, abrasive agents thiab hais txog.
9, lub pulp txheej txheem ntawm peb tsau:
Tsau concentration, tsau viscosity, ruaj kub.
Concentration: nyob rau hauv lub slurry, tag nrho qhuav qhov hnyav ntawm cov ntsiab lus slurry. Nyob rau hauv cov ntaub ntawv ntawm lwm yam kev mob tseem tsis hloov, lub concentration ncaj qha cuam tshuam rau sizing tus nqi, lub concentration yog siab, sizing tus nqi yog siab.
Kev txiav txim siab ntawm txoj kev concentration yog: (1) concentration meter: xws li Boomerang meter, qab zib meter, thiab lwm yam .. (2) Baking method. (3) Cov txheej txheem suav. Kev ua haujlwm tiag tiag, qhov concentration ntawm feem ntau siv slurry ntim, tseem hu ua cov khoom ruaj khov.
Viscosity: Lub viscosity ntawm slurry muaj feem xyuam rau kev nkag mus ntawm slurry. Viscosity yog me me, fluidity, nkag mus yog zoo dua, yog li ntawd lub adhesion ntawm cov fibers thiab tuav zoo dua, tsis tshua muaj txheeb ze slippage ntawm cov fibers, yog conducive rau kev txhim kho ntawm sizing, txo breakage.
Kev txiav txim siab ntawm viscosity txoj kev: (1) lub chaw kuaj mob feem ntau siv NDJ-79 hom teb viscosity tshuab. (2) Kev ua haujlwm ntau lawm feem ntau siv funnel viscometer.
Kub: nws yog qhov kub thiab txias thaum lub thickness thiab viscosity raug kho, thiab qhov kub ntawm cov slurry muaj feem xyuam rau lub viscosity ntawm slurry.
10, slurry immersion, phi re thiab slurry zaj duab xis kev ncaj ncees:
Kev ntub dej ntawm cov slurry, phi re, thiab kev ncaj ncees ntawm slurry zaj duab xis ncaj qha cuam tshuam rau qhov zoo ntawm cov xov slurry. Soaking thiab sizing yarn zog. Cov batch muaj feem xyuam rau qhov smoothness thiab abrasion tsis kam ntawm sizing yarn. Kev ncaj ncees ntawm zaj duab xis muaj feem xyuam rau kev puas tsuaj thiab cov plaub hau ntawm cov xov paj sizing.
Soaking: Nyob rau hauv tus txheej txheem ntawm sizing, sizing kua nkag mus rau hauv cov xov paj ua rau cov fibers sib txuas thiab ua kom lub zog.
Slurry batch: slurry nyob rau hauv cov xov paj sab nrauv txheej txheej ntawm slurry zaj duab xis, thiaj li hais tias lub nto ntawm slurry yarn smooth, txo cov plaub hau, weaving hnav kuj. Batch loj yuav cuam tshuam rau qhov zoo ntawm sizing, batch loj dhau, qhov nkag tau tsawg los ntawm qhov loj me, poob pulp ntau dua, weaving tshwm sim los ntawm brittle so; batch yog me me tsis tiav, yooj yim rau cov plaub hau.
Sizing zaj duab xis kev ncaj ncees: sizing nyob rau hauv cov xov paj nto txheej cov degree ntawm kev ncaj ncees ntawm sizing zaj duab xis.
11, nrog rau pulp quota:
Ib tuj ntawm qhuav warp yarn siv nyob rau hauv lub ntsiab tus nqi ntawm pulp (kg / ton) yog ib qho ntawm cov nyiaj txiag ntsuas ntawm accounting cov nqi khoom
Kev ntsuam xyuas kev lag luam ntawm cov khoom siv hluav taws xob kuj tseem siv tau rau ib lub 'meter' ntawm daim ntaub dawb huv los ntawm tus nqi ntawm cov ntaub so ntswg rau tus account rau (yuan / m)
12, sizing efficiency:
Laboratory ntsuas sizing tus nqi raws li tus txheej txheem tsim cov cai ntawm feem pua ntawm sizing tus nqi.
