Momwe mungagwiritsire ntchito hydroxyethyl cellulose mu utoto wa latex

1. Onjezani mwachindunji pogaya pigment: Njirayi ndi yosavuta ndipo imatenga nthawi yochepa. Njira zambiri ndi izi:

(1) Onjezani madzi oyeretsedwa oyenerera ku nthiti ya agitator odulidwa kwambiri (kawirikawiri, ethylene glycol, chonyowa ndi chopangira mafilimu onse akuwonjezeredwa panthawiyi)

(2) Yambani kuyambitsa mosalekeza pa liwiro lotsika ndikuwonjezera pang'onopang'ono hydroxyethyl cellulose

(3) Pitirizani kuyambitsa mpaka tinthu tating'onoting'ono tanyowa

(4) Onjezani antifungal wothandizira, PH chosinthira, ndi zina.

(5) Limbikitsani mpaka hydroxyethyl cellulose itasungunuka kwathunthu (kukhuthala kwa yankho kumawonjezeka kwambiri) musanawonjezere zigawo zina mu chilinganizo, ndikupera mpaka utoto.

2. Konzekerani mowa wa mayi kuti mugwiritse ntchito: Njira iyi ndi yokonzekeretsa mowa wa mayi mochuluka kaye, kenako onjezerani pa utoto wa latex. Ubwino wa njirayi ndikuti umakhala ndi kusinthasintha kwakukulu ndipo ukhoza kuwonjezeredwa mwachindunji ku utoto womalizidwa, koma uyenera kusungidwa bwino. Masitepe ndi njira ndizofanana ndi masitepe (1) - (4) mu Njira 1, kusiyana kwake ndikuti palibe chifukwa chothamangitsira kumeta ubweya wambiri, komanso ma agitator ena omwe ali ndi mphamvu zokwanira kusunga ulusi wa hydroxyethyl molumikizana. njira ntchito. Mutha. Pitirizani kusonkhezera mpaka kusungunuka kwathunthu mu viscous solution. Tiyenera kuzindikira kuti antifungal wothandizira ayenera kuwonjezeredwa kwa mowa wa amayi mwamsanga.

3. Pa phala phenology: Popeza zosungunulira organic ndi osauka zosungunulira hydroxyethyl mapadi, zosungunulira organic izi angagwiritsidwe ntchito kuphika phala. Zosungunulira zomwe zimagwiritsidwa ntchito kwambiri monga ethylene glycol, propylene glycol, ndi mafilimu opanga mafilimu (monga hexylene glycol kapena diethylene glycol butyl acetate), madzi oundana amakhalanso osungunulira bwino, choncho madzi a ayezi nthawi zambiri amagwiritsidwa ntchito pamodzi ndi zakumwa zamadzimadzi. Kukonzekera phala.

Phala-ngati hydroxyethyl cellulose akhoza kuwonjezeredwa mwachindunji ku utoto. Ma cellulose a hydroxyethyl atatupa mu phala. Akawonjezeredwa ku utoto, nthawi yomweyo amasungunuka ndi kukhuthala. Pambuyo powonjezera, ziyenera kugwedezeka mosalekeza mpaka hydroxyethyl cellulose itasungunuka kwathunthu ndi yunifolomu. 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. M'chilimwe, chinyezi chamadzi ambiri chimakhala chokwera kwambiri, ndipo sichiyenera kugwiritsidwa ntchito pa phala.

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 pa cellulose ya hydroxyethyl, ndikofunikira kupitilirabe mpaka yankho likuwonekera bwino komanso lomveka bwino.

2) Iyenera kusefedwa mu mbiya yosakaniza pang'onopang'ono, ndipo musawonjezere cellulose ya hydroxyethyl yomwe yapangidwa kukhala zotupa kapena mipira mwachindunji mumgolo wosakaniza.

3) Kutentha kwamadzi ndi pH yamadzi m'madzi kumakhala ndi ubale wofunikira ndi kusungunuka kwa cellulose ya hydroxyethyl, kotero chidwi chapadera chiyenera kuperekedwa kwa icho.

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.
