Chips&Slurry Zamadzi Zosungunuka Zamadzi Zosungunuka
Kumamatira kwabwino kwambiri;ili ndi mawonekedwe a mamolekyu ofanana ndi a polyester, ndipo amamatira bwino kwambiri ndi poliyesitala.Kumamatira ndi poliyesitala ndikwabwinoko kuposa PVA, acrylate, wowuma wosinthidwa ndi ma slurries ena.
Kusungunuka kwamadzi bwino;imasungunuka mosavuta m'madzi otentha pamwamba pa 80 ℃, palibe mpweya, palibe kupukuta, kumagwirizana bwino ndi wowuma, PVA, acrylic slurry, palibe mpweya, palibe stratification.
Low mamasukidwe akayendedwe ndi khola;imagwirizana ndi (kusasinthasintha kwakukulu, kuthamanga kwambiri, kutsika kwa viscosity) kukula, kulowa mwamphamvu, kosavuta kupeza malowedwe abwino, kuphatikiza kwa fiber, kumamatira kwatsitsi.
Filimu yakukula ndi yolimba;ndi yolimba, yosalala ndi yowonekera, yosweka mofanana pamene igawanika, ndipo ulusi ndi wosalala.Kutsegula kwa nsalu yoluka kumamveka bwino, komwe kumachepetsa kusweka kwa ulusi woluka komanso kumapangitsa kuti nsalu yoluka igwire bwino ntchito.
Kusintha PVA kungachepetse mtengo;PVA ikhoza kusinthidwa ndi 1: 2, yomwe ingachepetse kwambiri mtengo wa slurry pamaziko owonetsetsa kuluka.
Zokonda zachilengedwe;ikhoza kukhala alcoholysis, hydrolysis, kuwonongeka kwa alkali, photodegradation ndi kuwonongeka kwa tizilombo toyambitsa matenda.Sikuti ntchito yowonongeka ndi yabwino kuposa PVA, komanso mlingo wake ndi 1/2 wa PVA, womwe ungachepetse mtengo wa mankhwala onyansa.Ndi chilengedwe-wochezeka slurry.

Chilinganizo: Pamaziko a chilinganizo chomwe chilipo, voliyumu yonse yolimba imakhalabe yosasinthika, ndipo 1kg ya polyester slurry yosungunuka m'madzi imagwiritsidwa ntchito m'malo mwa 2kg PVA.Gawo losakwanira limaphatikizidwa ndi wowuma kapena wowuma wosinthidwa, ndipo kuchuluka koyenera kwa mafuta opangira mafuta ndi antistatic wothandizira kumawonjezedwa kuwonetsetsa kuti pafupifupi kukula kwake (mlingo weniweniwo udzakhala wotsika pang'ono).
Kukula: ikani madzi okwanira mu chidebe choyezera, yatsani kusakaniza, choyamba ikani wowuma, kenaka yikani poliyesitala yosungunuka m'madzi, gwedezani mokwanira, kenako onjezerani kutentha kwa pamwamba pa 95 ℃, kenako tsegulani valavu yaying'ono. wiritsani kwa mphindi zoposa 30, ndiye kuwonjezera mafuta, antistatic wothandizila kapena madzi slurry, wiritsani ndi kusakaniza bwino, ndiyeno ntchito pambuyo kuika voliyumu ndi mamasukidwe akayendedwe.
Gwiritsani ntchito motsogozedwa ndi akatswiri amisiri.
Panjira ya slurry, slurry wothandizira wokhala ndi zitsulo ziwiri kapena mchere wa heavy metal uyenera kupewedwa momwe angathere, komanso madzi olimba kwambiri apewedwe momwe angathere.Madzi olimba kwambiri amafunika kufewetsa musanagwiritse ntchito.Osagwiritsa ntchito NaOH ngati chowola panthawi yosakaniza slurry.Mtengo wa PH wa slurry uyenera kukhala pakati pa 6 ndi 7.
