Momwe mungagwiritsire ntchito hydroxyethyl cellulose mu utoto wa latex
1. Hydroxyethyl cellulose imagwiritsidwa ntchito popanga phala: Popeza kuti hydroxyethyl cellulose sivuta kusungunuka mu zosungunulira za organic, zosungunulira zina zitha kugwiritsidwa ntchito popanga phala.Madzi a ayezi nawonso samasungunuka bwino, motero madzi a ayezi nthawi zambiri amagwiritsidwa ntchito limodzi ndi zakumwa zamadzimadzi pokonzekera phala.Phala-ngati hydroxyethyl cellulose akhoza kuwonjezeredwa mwachindunji ku utoto wa latex.Hydroxyethyl cellulose yaviikidwa kwathunthu mu phala.Akawonjezeredwa ku utoto, amasungunuka mofulumira ndipo amakhala ngati thickener.Pambuyo powonjezera, pitirizani kuyambitsa mpaka hydroxyethyl cellulose itabalalitsidwa ndi kusungunuka.Nthawi zambiri, phala limapangidwa posakaniza magawo asanu ndi limodzi a organic zosungunulira kapena madzi a ayezi ndi gawo limodzi la hydroxyethyl cellulose.Pambuyo pa mphindi 5-30, cellulose ya hydroxyethyl imapangidwa ndi hydrolyzed ndikutupa mwachiwonekere.(Kumbukirani kuti chinyezi chamadzi ambiri chimakhala chokwera kwambiri m'chilimwe, choncho sayenera kugwiritsidwa ntchito popanga phala.)
2. Onjezani cellulose ya hydroxyethyl mwachindunji pogaya pigment: Njirayi ndi yosavuta ndipo imatenga nthawi yochepa.Njira yatsatanetsatane ndi iyi:
(1) Onjezani kuchuluka koyenera kwa madzi oyeretsedwa mumtsuko waukulu wa chosakanizira chometa ubweya wambiri (kawirikawiri, zothandizira kupanga mafilimu ndi zonyowetsa zimawonjezedwa panthawiyi)
(2) Yambani kuyambitsa mosalekeza pa liwiro lotsika komanso pang'onopang'ono komanso molingana onjezerani cellulose ya hydroxyethyl
(3) Pitirizani kusonkhezera mpaka tinthu tating’ono ting’onoting’ono tamwazikana ndi kunyowa
(4) Onjezani zowonjezera za anti-mildew kuti musinthe mtengo wa PH
(5) Onetsetsani mpaka cellulose yonse ya hydroxyethyl itasungunuka kwathunthu (kukhuthala kwa yankho kumawonjezeka kwambiri), kenaka yikani zigawo zina mu ndondomekoyi, ndikupera mpaka utoto upangidwe.
3. Konzani hydroxyethyl cellulose ndi mowa wamayi kuti mudzagwiritse ntchito mtsogolo: Njira iyi ndikupangira kuti mowa wa amayi ukhale wochuluka kwambiri, kenaka onjezerani ku utoto wa latex.Ubwino wa njirayi ndikuti umasinthasintha ndipo ukhoza kuwonjezeredwa mwachindunji ku utoto womalizidwa, koma uyenera kusungidwa bwino..Masitepe ndi njira ndizofanana ndi masitepe (1) - (4) mu njira 2, kusiyana kwake ndikuti palibe chowotcha chometa ubweya wambiri chomwe chimafunikira, ndipo ma agitator ena okha omwe ali ndi mphamvu zokwanira kuti hydroxyethyl fiber imwanidwe mofanana mu yankho ndi Can. .Pitirizani kusonkhezera mosalekeza mpaka kusungunuka kwathunthu mu njira ya viscous.Tiyenera kuzindikira kuti antifungal wothandizira ayenera kuwonjezeredwa ku mowa wa amayi a utoto mwamsanga.
4 Zinthu zofunika kuziganizira pokonza mowa wa hydroxyethyl cellulose
Popeza hydroxyethyl cellulose ndi ufa wokonzedwa, ndi wosavuta kuugwira ndi kuusungunula m'madzi malinga ngati zinthu zotsatirazi zikuyang'aniridwa.
(1) Isanayambe komanso itatha kuwonjezera hydroxyethyl cellulose, iyenera kugwedezeka mosalekeza mpaka yankho likuwonekera bwino komanso lomveka bwino.
(2) Iyenera kusefedwa pang'onopang'ono mu thanki yosakaniza, ndipo musawonjezere mwachindunji kuchuluka kwa hydroxyethyl cellulose yomwe yapanga zotupa kapena mipira mu thanki yosakaniza.
(3) Kutentha kwa madzi ndi pH mtengo m'madzi kumakhala ndi ubale wofunikira ndi kusungunuka kwa cellulose ya hydroxyethyl, kotero chidwi chapadera chiyenera kulipidwa.
(4) Osawonjezera zinthu za alkaline kusakaniza ufa wa hydroxyethyl cellulose usanalowedwe ndi madzi.Kukweza pH pambuyo pakunyowetsa kumathandizira kusungunuka.
(5) Momwe mungathere, onjezani anti-fungal agent msanga.
(6) Pamene ntchito mkulu mamasukidwe akayendedwe mapadi hydroxyethyl mapadi, ndende ya mowa mayi sayenera kupitirira 2.5-3% (ndi kulemera), apo ayi mowa mayi adzakhala ovuta kupirira.
Zomwe zimakhudza kukhuthala kwa utoto wa latex:
(1) Chifukwa cha kugwedezeka kwakukulu, chinyezi chimatenthedwa panthawi yobalalika.
(2) Kuchuluka kwa zokhuthala zina zachilengedwe pakupanga utoto ndi chiŵerengero cha kuchuluka kwa hydroxyethyl cellulose.
(3) Kaya kuchuluka kwa surfactant ndi kuchuluka kwa madzi ogwiritsidwa ntchito popanga utoto ndizoyenera.
(4) Pamene synthesizing latex, kuchuluka kwa okusayidi zili monga zotsalira chothandizira.
(5) Kuwonongeka kwa thickener ndi tizilombo.
(6) Popanga utoto, ngati masitepe owonjezera owonjezera ndi oyenera.
7 Kuchuluka kwa thovu la mpweya kumakhalabe mu utoto, m’pamenenso kukhuthala kwake kumakwera
