Ibyuma biremereye bidafite amazi Soluble Polyester Chips & Slurry
Kwizirika neza;ifite imiterere ya molekuline isa n'iya polyester, kandi ifatanye neza na polyester.Gufatanya na polyester nibyiza cyane kuruta PVA, acrylate, ibinyamisogwe byahinduwe nibindi byuma.
Amazi meza;irashobora gushonga byoroshye mumazi ashyushye hejuru ya 80 ℃, nta mvura igwa, nta ruhu, ihuza neza na krahisi, PVA, acrylic slurry, nta mvura igwa, nta stratifike.
Ubukonje buke kandi butajegajega;ihuza na (guhuzagurika cyane, umuvuduko mwinshi, ubukonje buke) uburyo bunini, kwinjira cyane, byoroshye kubona kwinjira neza, guhuza fibre, guhuza umusatsi.
Ingano ya firime irakomeye;irakomeye, yoroshye kandi iragaragara, iringaniye iyo igabanijwe, kandi umugozi uroroshye.Gufungura umwenda birasobanutse, bigabanya neza igipimo cyo kumeneka kwintambara no kunoza imikorere yimyenda.
Gusimbuza PVA birashobora kugabanya ikiguzi;PVA irashobora gusimburwa na 1: 2, irashobora kugabanya cyane igiciro cyihuse hashingiwe kuboha imyenda.
Ibidukikije byangiza ibidukikije;irashobora kuba alcoolise, hydrolysis, iyangirika rya alkali, gufotora no kwangirika kwa mikorobe.Ntabwo imikorere yangirika iruta PVA gusa, ariko kandi dosiye ni 1/2 gusa cya PVA, ishobora kugabanya ikiguzi cyo gutunganya imyanda.Nibidukikije byangiza ibidukikije.

Inzira: Ukurikije formulaire ihari, ubwinshi bukomeye ntibuhinduka, kandi 1kg amazi-soluble polyester slurry akoreshwa mugusimbuza 2kg PVA.Igice kidahagije cyongewemo na krahisi cyangwa yahinduwe na krahisi, kandi umubare ukwiye wibikoresho byamavuta hamwe na antistatike byongeweho kugirango harebwe igipimo cyagereranijwe (igipimo nyacyo kizaba kiri munsi gato).
Ingano: shyira amazi akwiye mu ndobo ingana, fungura kuvanga, ubanze ushyiremo ibinyamisogwe, hanyuma ushyiremo amazi ya elegitoronike ya polyester, ushire byuzuye, hanyuma uzamure ubushyuhe hejuru ya 95 ℃, hanyuma ufungure akayaga gato ko mu kirere kuri guteka muminota irenga 30, hanyuma ushyiremo amavuta, antistatic agent cyangwa flux slurry, guteka no kuvanga neza, hanyuma ubikoreshe nyuma yo gushyiraho amajwi nubwiza.
Koresha uyobowe nabatekinisiye babigize umwuga.
Muri formulaire ya slurry, ibishishwa byingirakamaro birimo ibyuma bihwanye cyangwa umunyu uremereye wibyuma bigomba kwirindwa uko bishoboka kose, kandi amazi afite ubukana bukabije nayo agomba kwirindwa kure hashoboka.Amazi afite ubukana bwinshi cyane agomba koroshya mbere yo kuyakoresha.Ntukoreshe NaOH nkumukozi ubora mugihe cyo kuvanga.Agaciro PH ya slurry igomba kuba hagati ya 6 na 7.
