Hydroxyethyl cellulose mu utoto wa emulsion

Njira yogwiritsira ntchito hydroxyethyl cellulose mu utoto wa latex

1. Hydroxyethyl cellulose yokhala ndi phala ngati phenology: chifukwa hydroxyethyl cellulose sasungunuka mosavuta mu zosungunulira za organic, zosungunulira zina za organic zitha kugwiritsidwa ntchito kupanga phala.Madzi oundana ndi osungunula oipa, choncho amagwiritsidwa ntchito mu phala ndi zakumwa za organic.Ma cellulose a hydroxyethyl a mawonekedwe a congee amatha kuwonjezeredwa mwachindunji mu utoto wa emulsii.Hydroxyethyl cellulose yakhutitsidwa mu mawonekedwe a phala.Akawonjezeredwa ku utoto, amasungunuka mwamsanga ndi kukhuthala.Pitirizani kuyambitsa mpaka hydroxyethyl cellulose itabalalitsidwa kwathunthu ndikusungunuka.Phala wamba amapangidwa posakaniza magawo asanu ndi limodzi a organic zosungunulira kapena madzi a ayezi ndi gawo limodzi la hydroxyethyl cellulose.Pakatha pafupifupi mphindi 5-30, hydroxyethyl cellulose imatsika ndikuwuka mowonekera.(Akuti chinyezi chamadzi m'chilimwe chimakhala chokwera kwambiri kuti chigwiritsidwe ntchito popanga phala.)

2. Onjezani cellulose ya hydroxyethyl mwachindunji ku pigment yopera: njira iyi ndi yophweka ndipo nthawi ndi yochepa.Njira zambiri ndi izi:

(1) Onjezani madzi oyera oyenera mu VAT yapamwamba iyenera kudula chowotcha (nthawi zambiri, zowonjezera zopangira mafilimu ndi zonyowetsa zikuwonjezedwa panthawiyi)

(2) Yambani kusonkhezera pa liwiro lotsika popanda kuyimitsa ndikuwonjezera pang'onopang'ono hydroxyethyl cellulose mofanana

(3) Pitirizani kusonkhezera mpaka tinthu tating’ono ting’onoting’ono tamwazikana ndi kunyowa

(4) Onjezani mildew inhibitor ndikusintha mtengo wa PH

(5) Limbikitsani mpaka mapadi onse a hydroxyethyl atasungunuka kwathunthu (kukhuthala kwa yankho kumawonjezeka kwambiri), kenaka yikani zigawo zina mu chilinganizo, ndikupera mpaka utoto.

3 hydroxyethyl mapadi ndi mayi madzi kuyembekezera: njira imeneyi choyamba okonzeka ndi apamwamba ndende ya mayi madzi, ndiyeno kuwonjezera lalabala utoto, ubwino njira imeneyi ndi kusintha, akhoza mwachindunji kuwonjezera utoto anamaliza mankhwala, koma yosungirako yoyenera.Masitepe ndi njira zofanana ndi masitepe (1) - (4) mu Njira 2, kupatulapo kuti agitator yodula kwambiri sikufunika ndipo ma aggers ena okha omwe ali ndi mphamvu zokwanira kusunga ulusi wa hydroxyethyl wobalalika mu yankho amagwiritsidwa ntchito.Pitirizani kuyambitsa mpaka utasungunuka kwathunthu mu njira wandiweyani.Dziwani kuti: antimildew wothandizira ayenera kuwonjezeredwa posachedwa mu mowa wa amayi wa utoto.

4 Zinthu zofunika kuziganizira pokonzekera mowa wa hydroxyethyl cellulose

Popeza hydroxyethyl cellulose ndi mankhwala granular ufa, n'zosavuta kugwira ndi kupasuka m'madzi ndi zodzitetezera zotsatirazi.

(1) Isanayambe kapena itatha kuwonjezera hydroxyethyl mapadi, ayenera kupitiriza oyambitsa, mpaka yankho kwathunthu mandala ndi bwino.

(2) Ndikofunikira kusefa cellulose ya hydroxyethyl mu thanki yosonkhezera pang'onopang'ono.Osawonjezera mochuluka kapena mwachindunji mu thanki yosonkhezera.

(3) Kusungunuka kwa cellulose ya hydroxyethyl mwachiwonekere kumagwirizana ndi kutentha kwa madzi ndi pH mtengo wa madzi, kotero chisamaliro chapadera chiyenera kuperekedwa kwa izo.

(4) Osawonjezera zinthu zina zofunika kusakaniza ufa wa hydroxyethyl cellulose usanavidwe ndi madzi.Kukweza pH pambuyo pakuviika kumathandiza kusungunuka.

(5) Momwe kungathekere, kuwonjezera koyambirira kwa mildew inhibitor.

(6) Pamene ntchito mkulu mamasukidwe akayendedwe hydroxyethyl mapadi, ndende ya mowa mayi sayenera kuposa 2.5-3% (ndi kulemera), apo ayi mowa mayi n'kovuta ntchito.

Zomwe zimakhudza kukhuthala kwa utoto wa latex:

(1) Chifukwa cha kugwedezeka kwambiri komanso chinyezi chambiri pomwaza.

(2) kuchuluka kwa zokhuthala zina zachilengedwe mu utoto wa utoto ndi gawo la kuchuluka kwa cellulose ya hydroxyethyl.)

(3) kuchuluka kwa activator yapamtunda ndi madzi mumtundu wa utoto ndizogwirizana.

(4 mu kaphatikizidwe ka latex, chotsalira chothandizira oxide zili mu nambala.

Kukokoloka kwa tizilombo toyambitsa matenda.

6 popanga utoto, dongosolo la masitepe owonjezera thickener ndiloyenera.

Kuchuluka kwa mpweya wotsalira mu utoto, kumapangitsanso kukhuthala kwamphamvu
