Kev ntxuav linen yog ib txoj haujlwm ceev faj. Muaj ntau tus thawj coj. Lub tshuab ntxhua khaub ncaws tau qhib rau ntau xyoo, tab sis muaj ntau yam kev khiav hauj lwm thiab kev ntxuav cov txheej txheem tseem tsis tau paub, xws li linen pre-sashing, dej neutralization, softening, deliming thiab bleaching.
Tom qab cov ntaub dhau los ntawm lub ntsiab ntxuav thiab bleaching, lub ntxhua khaub ncaws los txog rau thaum xaus, tab sis nyob rau hauv thiaj li yuav ua kom cov ntaub huv si yuav tsum tau chemically kho raws li cov hom phiaj sib txawv kom tau raws li cov neeg siv cov ntaub ntawv zoo tshaj plaws, nws yuav tsum tau kho. tom qab ntxuav. . Kev kho tom qab ntxuav nrog rau 6 txheej txheem: watering, softening, neutralizing, whitening, sizing thiab dehydrating.
1. Hla dej
Txawm hais tias nws yog tsev ntxhua khaub ncaws lossis ntxhua khaub ncaws hauv tsev, tag nrho cov ntxhua khaub ncaws zoo yuav tsum tau lav. Ntxiv nrog rau kev tswj hwm ntawm lub ntsiab ntxuav thiab ntxiv cov tshuaj dawb, cov dej sib txuas yuav tsum tsis txhob ignored.
Feem ntau, nyob rau hauv cov txheej txheem ntxhua khaub ncaws, txhawm rau tswj kom muaj qhov loj txaus concentration gradient nruab nrab ntawm cov dej thiab cov khoom siv ntxhua khaub ncaws uas muaj nyob rau hauv cov ntaub yuav tsum tau ntxuav, thiab txhawm rau txhim kho cov dej zoo dua, cov dej siab feem ntau yog siv. Tus naj npawb ntawm cov dej dhau los yog ze ze rau kev ua haujlwm ntawm cov ntaub thiab kev ua haujlwm ntawm cov tshuaj ntxuav tes siv. Ntshiab paj rwb fiber ntau muaj kev nqus dej zoo heev. Thaum lub sij hawm ntxuav, nws absorbs ntau zaus ntau dua cov tshuaj pleev ib ce. Tib cov paj rwb fiber ntau muaj qhov sib txawv ntawm cov dej nqus vim muaj cov qauv sib txawv. Cov phuam ntsuab yog zoo dua li cov qauv weave. Cov paj rwb fiber ntau muaj cov khoom nqus dej zoo heev. Rau cov ntaub ntxuav nrog detergents uas muaj ib tug loj feem ntawm alkalis, vim alkalis muaj tsis zoo rinsing kev ua tau zoo, kuj yuav tsum tau ntau zaus ntawm dej. Kev sim cov ntaub ntawv qhia tau hais tias lub tshuab ntxhua khaub ncaws 50 kg Tom qab cov phuam ntxuav nrog dej siab, cov phuam muaj 16.7 feem pua ntawm cov tshuaj pleev qhov seem tom qab thawj zaug ntxuav, 3.23 feem pua tom qab ntxuav zaum ob, thiab {{7 }}.108 feem pua tom qab qhov thib peb ntxuav, Tom qab plaub dhau, nws yog 0.0117 feem pua. Yog li ntawd, 3 mus rau 4 kis feem ntau siv tau rau feem ntau cov ntaub.
Tom qab lub ntsiab ntxuav, cov ntaub yuav tsum tau ib tug npaum li cas ntawm thermal zog kom dhau los ntawm cov dej, tab sis muaj ib tug hauv paus ntsiab lus rau xaiv qhov kub thiab txias, thiab cov dej kub yuav tsum tau txo nyob rau hauv feem rau txhua lub sij hawm. Piv txwv li, yog tias qhov ntsuas kub tseem ceeb yog 80 feem pua, ces thawj qhov dej kub yog 70 feem pua, qhov dej thib ob yog 55 feem pua, thiab qhov dej thib peb yog 35 feem pua.
Thaum siv cov dej siab, lub sij hawm yuav tsum yog 1.5-3 feeb, lub sij hawm ntawm lub tshuab ntxhua khaub ncaws hauv qab 50 kg yuav yog 1.5-2 feeb, thiab lub sij hawm siab tshaj 50 kg yuav yog {{ 6}} feeb. Dongguan peb-legged miv linen detergent chaw tsim tshuaj paus
2. Mos
Tom qab ua tiav lub ntsiab ntxuav thiab tshuaj dawb, ib co xis, mos, thiab fluffy fabrics, yuav tsum tau mus rau lub softening txheej txheem tom qab ntxuav kom tiav lub hom phiaj.
Softness: Tom qab lub ntsiab ntxuav thiab bleaching ntawm cov ntaub, txawm hais tias nws tau ua tiav zoo huv si, nws tsis yog mos heev. Cov txheej txheem softening yog siv lub softener, uas yog dispersed nyob rau hauv dej thiab muaj ib tug zoo affinity rau cov ntaub los ua cov ntaub fiber ntau cov txheej txheem ntawm lub sab hauv smoothness mus rau ib tug zoo lub xeev, softness, fluffy thiab antistatic nyhuv,
Cov txheej txheem Softening: Thaum cov ntaub dhau los ntawm dej rau lub sijhawm kawg, ntxiv cov softener los ntawm qhov chaw noj mov thaum cov dej kub nce mus txog qhov kub ntawm 20 degrees, thiab khaws cov dej kom mos thiab ntxuav li 5 feeb.
Softness yuav tsum tau: thaum softening, nws yuav tsum tau siv nruj me ntsis raws li tus nqi teev nyob rau hauv cov lus piav qhia ntawm softener khoom. Kev siv ntau dhau yuav ua rau cov ntaub dyes hloov xim. Tam sim no, softeners yog tag nrho cov cationic softeners thiab yuav tsum tsis txhob siv ua ke nrog fluorescent whitening agents. Lub sijhawm yuav tsum tau hloov pauv.
3. Neutralization
Dongguan peb-legged miv linen detergent chaw tsim tshuaj paus, vim yog cov alkalis, chlorine, thiab calcium uas muaj nyob rau hauv cov kua ntxhua khaub ncaws thaum lub ntsiab ntxuav thiab bleaching, thaum nws yog rhuab thiab kho nrog dej. Vim muaj kev cuam tshuam ntawm lub tshuab ntxhua khaub ncaws thiab lwm yam, nws tsis tuaj yeem lav tias cov tshuaj no yuav tsis nyob hauv cov ntaub, uas yuav ua rau cov ntaub dawb tig grey los yog daj, cuam tshuam cov xim vividness ntawm cov ntaub xim, thiab ua rau cov ntaub dawb hloov grey los yog daj. ntaub xav nyuaj. Txhawm rau tshem tawm cov khoom seem no, nws yog ib qho tsim nyog yuav tsum ua kom tiav cov txheej txheem ntxuav ntawm neutralization. Tus neeg saib xyuas cov kua qaub nruab nrab yog siv los txo cov tshuaj alkali kom cov pH tus nqi ntawm cov ntaub npuag nyob nruab nrab ntawm 5.8-6.5, thiab ua kom muaj kev xav zoo. Neutralization tshem tawm calcium oxide thiab calcium chloride thaum ntxuav cov ntaub kom ua tiav qhov muag muag. Nyob rau tib lub sijhawm, ntxiv cov kua qaub nruab nrab thaum hla dej yuav txo cov sijhawm dej hla thiab txuag lub zog.
Neutralization txheej txheem: qhov thib ob los yog thib peb hla dej, thaum dej kub yog 30 mus rau 40 degrees, ntxiv ib tug tsim nyog tus nqi ntawm neutralizing acid los ntawm qhov chaw nres nkoj pub thiab ntxuav rau 3 mus rau 5 feeb.
Qhov yuav tsum tau muaj: Tus nqi ntawm neutralizing acid feem ntau tswj ntawm {{0}}.2 mus rau 0.3 feem pua. Hauv kev ua haujlwm tiag tiag, nws yog qhov tsim nyog los ntsuas pH tus nqi ntawm cov tshuaj pleev ib ce tom qab ntxuav nrog neutralizing acid kom paub tseeb tias cov kua qaub nyob hauv nws, kom tsis txhob cua sov thiab txias ntawm cov ntaub kom corrode cov cuab yeej thiab adhesion ntawm cov ntaub tom qab ziab. .
4. Qhov loj me
Dongguan peb-legged miv linen detergent chaw tsim tshuaj paus, paddle kauj ruam yog tsuas yog rau ntaub pua rooj, napkins, ib co khaub ncaws, thiab lwm yam paj rwb fabrics los yog mixed fiber fabrics nyob rau hauv catering kev lag luam. Kev kho kom loj tuaj yeem ua rau saum npoo ntawm cov ntaub sizing tawv, tiv thaiv cov fiber ntau los ntawm fluffing, thiab muaj qhov zoo thiab zoo nkauj. Nyob rau tib lub sijhawm, nws tseem muab cov txheej txheem tiv thaiv rau ntawm qhov chaw ntawm cov ntaub sizing, uas tiv thaiv kev nkag mus ntawm cov av mus rau qee qhov, thiab tseem tuaj yeem ua rau cov ntaub sizing vim qhov sib txuas ntawm tus neeg sawv cev sizing tuaj yeem muab cov fiber ntau. ib qho kev ntxiv dag zog rau cov nyhuv, thiab nws tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev nthuav dav kev pabcuam lub neej ntawm cov ntaub.
Thaum cov ntaub yog qhov loj me, vim qhov ntub dej thiab nkag mus ntawm slurry, tus txheeb ze slippage ntawm cov fiber ntau thaum raug rau sab nraud quab yuam yog tiv thaiv, thiab vim yog cohesion thiab nqus, thiab diffusion ntawm slurry nws tus kheej, cov ntub dej thiab nkag mus ntawm cov ntaub. cov slurry ua rau cov slurry thiab cov ntaub Lub cev muaj peev xwm ntawm cov fibers yuav tsim ib tug ruaj txheej ntawm cov ntaub ntawv thaum raug rau ib tug tej yam nqi ntawm tshav kub. Dongguan peb-legged miv linen detergent chaw tsim tshuaj paus
Muaj ntau ntau hom sizing agents. Nyob rau hauv kev pom ntawm cov yam ntxwv ntawm cov ntaub fibers, cov nquag siv sizing agents yuav tsum muaj cov yam ntxwv nram qab no:
1. Nws muaj lub siab cohesive quab yuam thiab qee lub zog nplaum, uas tuaj yeem tsim ib txheej ntawm cov fiber ntau.
2. Muaj peev xwm ua kom muaj zog fiber ntau
3. Nws yog ib qho yooj yim los ntxuav tawm thiab yuav tsum tsis muaj tsw ntxhiab tsw
4. Tom qab sizing, xim nto ntawm cov ntaub fiber ntau yuav tsis cuam tshuam.
