Momwe mungagwiritsire ntchito hydroxyethyl cellulose mu utoto wa mochedwa.

Hydroxyethyl celluloseAmagwiritsidwa ntchito kwambiri pa utoto wa latex, emulsion utoto ndi zokutira, momwe mungagwiritsire ntchito hydroxethyl cellulose mu utoto wa mochedwa?

1. Onjezani mwachindunji ku utoto wambiri

Njirayi ndiyosavuta kwambiri ndipo imatenga kanthawi kochepa. Masitepe atsatanetsatane ali motere:

.

(2) Yambitsani kusuntha mwachangu ndikuwonjezera pang'onopang'ono hydroxyethyl cellulose

(3) Pitilizani kudzutsa mpaka tinthu tonyowa

.

(5)Muziganiza mpaka zonse hydroxethyl celluloseKusungunuka kwathunthu (mamasukidwe a yankholi kumachulukitsa kwambiri) musanawonjezere zinthu zina mu kapangidwe kake ndikukupera mpaka lacquer imapangidwa.

2. Kukhala ndi zakumwa za amayi

Njirayi ili ndi zida zokhala ndi zakumwa zapamwamba kwambiri zakumwa zoledzeretsa kenako ndikuwonjezera utoto wa latex. Ubwino wa njirayi ndikuti umasinthasintha kwambiri ndipo amatha kuwonjezeredwa ndi utoto womalizidwa, koma uyenera kusungidwa bwino. Njira ndi njira zofanana ndi masitepe (1) - (4) mu njira 1, kupatula kuti woyambitsa alibe mphamvu yokwanira . angathe. Pitilizani kusangalatsa mpaka kusungunuka kwathunthu kukhala yankho la ma viscous. Tiyenera kudziwa kuti nkhungu yolepheretsa imayenera kuwonjezeredwa kwa amayi omwe amamwa mowa msanga.

3. Ndi phala

Popeza zosungunulira zachilengedwe ndi zosungunulira bwino kwa hydroxethyl cellulose, ma soric solic amatha kugwiritsidwa ntchito popereka phala. Zomwe zimagwiritsidwa ntchito kwambiri monga Ethylene Glycol, Propylene Glycol, ndi ma filimu (monga hexene kapena madzi oundana amagwiritsidwa ntchito ndi madzi okhazikika omwe ali ndi phala. Porridge-ngati hydroxyethyl cellulose imatha kuwonjezeredwa mwachindunji pa utoto. Hydroxyethyl cellulose yakhala yonyowa mokwanira mu phala. Mukawonjezeredwa pa utoto, imasungunuka nthawi yomweyo ndi kukula. Pambuyo kuwonjezera, ndikofunikira kupitiliza kukhala ndi hydroxethyl cellulose yosungunuka kwathunthu komanso yosasunthika. Nthawi zambiri, phala limasakanikirana ndi gawo la zosungunulira kapena madzi oundana ndi gawo la hydroxethyl cellulose. Pakatha pafupifupi mphindi 5 mpaka 30, hydroxyethyl cellulose ndi hydrolyzid komanso amatuluka modabwitsa. Mwambiri, chinyezi chamadzi m'chilimwe chili chachikulu kwambiri ndipo sichiyenera kugwiritsidwa ntchito pofiyira.

4. Kukwaniritsa mukamagwiritsa ntchito hydroxyethyl cellulose mowa

Popeza hydroxyethyl cellulose (hec)Ndi granule yoyatsidwa, ndikosavuta kusamalira madzi bola ngati zinthu zotsatirazi sizitchulidwa.

.

(2) Iyenera kukhala yovuta pang'onopang'ono mu thanki yosakanikirana. Osawonjezera ma hydroxyethyl cellulose omwe apangidwe kukhala chipikacho komanso mawonekedwe owoneka bwino mu thanki yosakanikirana.

.

. Kuchulukitsa PH pambuyo kudzutsa kumathandizira kusungunuka.

(5) Onjezani zoletsa za nkhungu posachedwa.
