Kev faib tawm ntawm cov ntawv coated tuaj yeem raug cais raws li cov ntawv tso tawm yas thiab cov ntawv tsis muaj yas tso tawm; Silicone tso daim ntawv thiab cov ntawv tsis muaj silicone tuaj yeem raug cais raws li tus neeg tso tawm.
Muaj cov ntawv yas coated, vim tias tus neeg tso tawm muaj qee yam permeability. Yog tias tsis muaj qhov cuam tshuam, tus neeg sawv cev tso tawm yuav nkag mus rau sab hauv ntawm daim ntawv, uas ua rau muaj ntau yam tsis zoo, xws li kev kho tsis zoo thiab kev siv tus neeg tso tawm ntau dhau (tus nqi siab). Yog li ntawd, kev kho cov txheej txheem yas (feem ntau hu ua zaj duab xis txheej) yuav tsum tau ua rau ntawm daim ntawv. Polyethylene (PE) hais feem ntau yog siv rau txheej zaj duab xis nyob rau hauv Suav teb, thiab lub melt index yuav tsum yog hais txog 7. Domestic PE hais feem ntau yog 1c7a ntawm Yanshan Petrochemical. Muab faib ua ib daim ntawv tso tawm thiab ob daim ntawv tso tawm yas; Cov ntawv tso tawm tsis yog yas feem ntau suav nrog lwm cov ntawv tso tawm nrog kev kho tshwj xeeb, xws li grasin thiab CCK.
1. Daim ntawv tso tawm zaj duab xis
Daim ntawv tso tawm yog tsim los ntawm txheej tus neeg sawv cev tso tawm ntawm qhov chaw ntawm daim ntawv hauv paus tom qab tau coated.
Vim tias muaj cov ntaub plaub thiab cov fibers nyob rau saum npoo ntawm daim ntawv, zaj duab xis yuav tsum tau coated rau qee qhov nyiaj kom ntseeg tau tias tsis muaj qhov nkag mus, cov roj silicone yuav tsis nkag mus rau hauv daim ntawv, thiab yuav tsis muaj qhov tsis zoo. peeling. Feem ntau, tus nqi ntawm zaj duab xis coated ntawv yog 16 grams ib square meter. Nws tau hais tias Wenzhou tau ua tiav 11 13 grams ib square meter, uas yog heev ze rau zaj duab xis coated cov ntaub ntawv ntawm txawv teb chaws advanced khoom. Txoj kev xav, tsuav yog daim kab xev tuaj yeem rub tawm ntawm daim ntawv tso tawm, qhov tsawg dua qhov tso cai rau cov yeeb yaj kiab.
Daim ntawv tso tawm zaj duab xis tuaj yeem muab faib ua ib qho drench thiab ob chav dej. Feem ntau, ib daim ntawv -ib sab tso tawm yog ib qho dej ntws. Tau kawg, kuj tseem muaj ob chav dej da dej ib zaug -ib sab tso tawm daim ntawv, vim tias qhov chaw tso tawm muaj cov zaj duab xis tuab, uas feem ntau yog 20 grams, thiab qhov tsis tso tawm saum npoo yog feem ntau 15 grams nyias. Cov ntawv tso tawm no kuj yog tiaj tus.
Yog tias nws yog daim ntawv coated nrog ob npaug - sab txheej txheej ntawm 22 grams, nws yog qhov tsim nyog rau ob - sab tso tawm daim ntawv.
Txhua daim ntawv ntoo yog feem ntau siv rau cov ntawv tso tawm zaj duab xis, tshwj xeeb tshaj yog hauv kev lag luam hluav taws xob. Yog tias cov ntawv straw pulp raug xaiv, yuav muaj ntau cov ntawv khib nyiab thiab yooj yim tawg cov npoo thaum txiav tuag.
Txhua daim ntawv ntoo yog feem ntau hu ua kraft ntawv, xws li cov xim kraft ntawv (feem ntau hu ua Benniu), ntawv dawb kraft (feem ntau hu ua Bainiu), daj kraft ntawv (feem ntau hu ua Japanese daj xim nyuj) thiab xiav kraft ntawv ( feem ntau hu ua Indonesian xiav xim nyuj).
Tau kawg, nws tseem tuaj yeem siv ob daim ntawv offset nrog tag nrho cov ntoo pulp ua ntawv hauv paus, daim duab duab ua ntawv hauv paus, ntawv coated, ntawv whiteboard, daim npav nyuj, daim ntawv mis nyuj thiab lwm yam.
Ntev npaum li daim ntawv yas ceev ntawm zaj duab xis tuaj yeem ua tau raws li qhov yuav tsum tau ua, tsuav yog tias cov yeeb yaj kiab tsis muaj qhov nkag mus thiab cov yeeb yaj kiab tsis sib xws thiab tiaj tus, nws yuav tsum tau hais tias txhua daim ntawv tuaj yeem siv los ua cov ntawv hauv paus.
2. Grasin tso daim ntawv
Grasin puag ntawv yog tsim los ntawm overpressure thiab txheej tso tawm tus neeg sawv cev.
Grasin yog tshwj xeeb tshaj yog haum rau tuag- txiav factories vim nws compactness zoo tom qab super calendering.
Vim tias cov grasin hauv tsev tsuas tuaj yeem tsim tau 60 80g kom muaj nuj nqis, thaum tuag- txiav cov chaw tsim khoom nyiam siv ntau tshaj 100g kom muaj nuj nqis, xws li 120g thiab 140g. Nws muaj qee yam pob tshab, tawv tawv thiab zoo tuag- txiav kev ua haujlwm. Txhua tus cia siab rau cov ntawv hauv paus, tab sis txij li qhov pib ntawm cov ntawv hauv paus yog 20 tons ntawm ib lub thawv, thiab nws yuav tsum tau booked peb lub hlis ua ntej, qhov kev txiav txim yuav tsum tau them tag nrho. Ntau tus neeg tsim tawm txheej hauv tsev xav tias nws tsis muaj qhov tseem ceeb.
3. CCK tso daim ntawv
CCK puag daim ntawv yog ib daim ntawv tso tawm uas tsim los ntawm txheej txheej ntawm cov av nplaum tshwj xeeb rau saum npoo thiab tom qab ntawd txheej tso tawm tus neeg sawv cev.
Vim nws zoo heev kub tsis kam, nws yog dav siv nyob rau hauv carbon fiber kev lag luam.
Cov av nplaum ntawm CCK puag daim ntawv yog yooj yim heev los rhuav tshem silicone, yog li ob peb CCK tso tawm daim ntawv tsim nyob rau hauv Tuam Tshoj tuaj yeem dhau qhov kev xeem.
4. Lwm cov ntawv tso tawm
Tsis tas li ntawd, qee cov ntawv tso tawm tau siv dav hauv ntau lub lag luam, thiab qee qhov tsis siv cov neeg tso tawm. Piv txwv li, cov ntawv luam ntawv cov nroj tsuag feem ntau siv cov kua roj vanish uas yuav tsum tau tso tawm, uas tseem yuav muaj peev xwm tso tawm. Tau kawg, kev ua haujlwm ntawm cov kua nplaum yog qhov tsis muaj zog heev. Txwv tsis pub, qhov kev tso tawm peev xwm no tsis muaj txiaj ntsig. Tsis tas li ntawd, qee cov ntaub ntawv tso tawm uas tsim nrog cov kua nplaum tshwj xeeb thiab lwm cov qauv siv nyiaj rau kev lag luam me me.
Kev lag luam hluav taws xob siv cov ntawv tsis tshua muaj tseeb (tso tawm cov ntawv tsim los ntawm cov chaw ua haujlwm tsis tu ncua nrog kev ruaj ntseg zoo thiab muab kev lees paub), feem ntau yog daim ntawv garbled (tso ntawv siv ib zaug nyob txawv teb chaws lossis muaj qhov tsis zoo). Lub Hoobkas gluing yeej siv cov ntawv tiag.

Nco tseg: daim ntawv coated tsuas yog cov ntawv hauv paus thiab cov ntawv coated. Yog tias nws yog daim ntawv silicone, nws txhais tau tias tag nrho peb hom ntawv
(4), raws li ib leeg thiab ob sab
A. Ob chav silicon ib lub foob txhais tau hais tias ib sab yog cov roj silicone thiab lwm sab tsuas yog coated, uas yuav txhim kho kev huv.
B. Ob chav silicone hais txog cov roj silicone ntawm ob sab
C. Ib leeg silicon
D. Coated ntawv, kuj hu ua dawb yas ntawv
