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 sasungunuka bwino, choncho madzi a ayezi nthawi zambiri amagwiritsidwa ntchito ndi zakumwa za organic pokonzekera phala.Phala-ngati hydroxyethyl cellulose akhoza kuwonjezeredwa mwachindunji ku utoto wa latex.Ma cellulose a hydroxyethyl atatupa mu phala.Akawonjezeredwa ku penti, amasungunuka mwamsanga ndipo amachititsa kuti thupi likhale lolimba.Pambuyo powonjezera, ndikofunikirabe kupitilirabe mpaka hydroxyethyl cellulose itabalalitsidwa ndikusungunuka.Nthawi zambiri, phala limasakanizidwa ndi 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.(Akuti chinyontho chamadzi ambiri chimakhala chokwera kwambiri m'chilimwe, ndiye kuti sichiyenera kugwiritsidwa ntchito ngati phala.)
2. Onjezani cellulose ya hydroxyethyl mwachindunji pogaya pigment: Njirayi ndi yosavuta ndipo imatenga nthawi yochepa.Njira yatsatanetsatane ndi iyi:
(1) Onjezani madzi oyera oyenerera ku mtsuko wa chowombera chodula kwambiri (kawirikawiri, zida zopangira 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 tomwe tamwazikana mofanana ndi kunyowa
(4) Onjezani zowonjezera za antifungal kuti musinthe mtengo wa PH
(5) Limbikitsani mpaka ma cellulose onse a hydroxyethyl atasungunuka kwathunthu (kukhuthala kwa yankho kumawonjezeka kwambiri), kenaka yikani zigawo zina mu ndondomekoyi, ndikupera mpaka zikhale utoto.
3. Konzani hydroxyethyl cellulose ndi mowa wamayi kuti mugwiritse ntchito: Njira iyi ndi yopangira mowa wamayi mochuluka kaye, kenako onjezerani pa 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 chifukwa chothamangitsira kumeta ubweya wambiri, komanso zosokoneza zina zomwe zimakhala ndi mphamvu zokwanira kusunga ulusi wa hydroxyethyl mofanana. solution amagwiritsidwa ntchito.Mutha.Pitirizani oyambitsa zonse mpaka kwathunthu kusungunuka mu viscous yankho.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 kugwira ndi kusungunuka m'madzi malinga ngati zinthu zotsatirazi zikudziwika.
(1) Isanayambe komanso itatha kuwonjezera hydroxyethyl cellulose, iyenera kugwedezeka mpaka yankho likuwonekera bwino komanso lomveka bwino.
(2) Iyenera kusefedwa mu mbiya yosakaniza pang’onopang’ono.Osawonjezera mwachindunji cellulose ya hydroxyethyl yomwe idapangidwa kukhala zotupa ndi mipira mu mbiya yosakanikirana yochulukirapo kapena mwachindunji.
(3) Kutentha kwa madzi ndi pH mtengo m'madzi kumakhala ndi ubale wofunikira pakutha kwa cellulose ya hydroxyethyl, kotero chidwi chapadera chiyenera kulipidwa.
(4) Osawonjezera zinthu za alkaline kusakaniza ufa wa hydroxyethyl cellulose usanalowedwe ndi madzi.Kukweza pH pokhapokha kunyowetsa kumathandizira kusungunuka.
(5) Momwe mungathere, onjezani antifungal wothandizira mwachangu momwe mungathere.
(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) Chinyezicho chimatenthedwa kwambiri pakubalalika chifukwa cha kugwedezeka kwakukulu.
(2) Mlingo wa zokhuthala zina zachilengedwe ndi kuchuluka kwa mlingo wa hydroxyethyl cellulose mu fomula ya utoto.)
(3) Kaya kuchuluka kwa surfactant ndi kuchuluka kwa madzi mu fomula ya utoto ndizoyenera.
(4 Popanga latex, kuchuluka kwa chothandizira chotsalira ndi ma oxides ena.
5 Kukokoloka kwa tizilombo toyambitsa matenda.
6 Pakupanga utoto, kodi kutsatizana kwa masitepe owonjezera zokometsera ndikoyenera?
7 Kukwera komwe kumatulutsa mpweya wotsalira mu utoto, m'pamenenso kukhuthala kumakwera
