Utoto wa utoto

Utoto wa utotoHec hydroxethyl cellulose ndi mtundu wa polymer yopanda madzi osungunuka, yoyera kapena yachikasu kapena yopanda madzi, ndipo kuchuluka kwa zonyansa kumawonjezera kutentha kwambiri sol sol. Ili ndi pH yanu yokhazikika komanso kusintha kwa mafashoni pang'ono mu Ph2-12. Hec ali ndi luso lapamwamba kwambiri komanso hygroscopic luso, ndipo ali ndi madzi olimba. Njira yake yamadzimadzi imagwira ntchito moyenera komanso zinthu zina zowoneka bwino zimakhala ndi pseudoplastity. Itha kupangidwa mu filimu yowoneka bwino yowoneka bwino yolimba, yosayipitsidwa mosavuta ndi mafuta, osakhudzidwa ndi kuwala, ali ndi filimu yosungunuka yamadzi ya Hei. Pambuyo pa chithandizo, hec imagwirizanitsa ndipo sagwirizana m'madzi, koma kusungunuka pang'onopang'ono. PH imatha kusinthidwa mpaka 8-10 ndikusungunuka mwachangu.

Zinthu zazikulu

Hydroxyethyl cellulose(Hec)Kodi zitha kusungunuka m'madzi ozizira ndi madzi otentha, ndipo ilibe mawonekedwe a gelve. Ili ndi mitundu yambiri, yosungunuka ndi mafayilo. Ili ndi kukhazikika kwa matenthedwe (pansipa 140 ° C) ndipo sikupanga pansi pa acidic mikhalidwe. mpweya. Ma hydroxyethyl cellulose (hec) amatha kupanga filimu yowonekera, yomwe ili ndi mawonekedwe osakhala a ionic omwe samayanjana ndi mayoni ndipo ali ndi mgwirizano wabwino.

Monga colloid yoteteza, utoto wa utoto umatha kugwiritsidwa ntchito kwa vinyl acetate emumerization polymerization kuti musinthe dongosolo la polymerization. Popanga zinthu zomalizidwa kuti apange pigment, zosefera ndi zina zowonjezera zomwe zimabalalika, khola ndikuwonetsa kukula. Itha kugwiritsidwanso ntchito kwa ma styrene, acrylic, ma acrylic ndi ena oyimitsidwa ngati osakanizidwa, utoto wa mochedwa amatha kusintha kwambiri, ndikusintha magwiridwe antchito.

Malo Maphunziro 

Njira yogwiritsira ntchito hydroxyethyl cellulose Hec mu madzipenti

1. Onjezani mwachindunji mukamakupera: Njira iyi ndiyosavuta, ndipo nthawi yomwe imagwiritsidwa ntchito ndi yochepa. Masitepe atsatanetsatane ali motere:

.

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

(3) Pitilizani kudzutsa mpaka tinthu tating'onoting'ono tanyowa

2. Kukhala ndi Madzi Amadzimadzi Akudikirira: Njirayi imakhala ndi mwayi wokhazikika wa amayi, kenako kuwonjezera pa utoto wa latch . Masitepe ndi njira zofanana ndi zotengera (1) - (4) mu njira 1, kupatula kuti anitator ocheperako osafunikira ndi mphamvu yokwanira kuti ulusiwu ukhale wokwanira. Pitilizani kusuntha mpaka itasungunuka kwathunthu. Dziwani kuti woletsa misozi ayenera kuwonjezeredwa ndi amayi awo mowa momwe mungathere.

3. Purridge ngati phenology: Popeza ortic sodic ndi ma solrocyethyl cellulose, osungunuka awa amatha kukhala ndi phala ndi phala. Zomwe zimagwiritsidwa ntchito kwambiri monga Ethylene Glycol, Propylene Glycol, ndi othandizira mafilimu (monga hexudecanol kapena madzi oundana nthawi zambiri amagwiritsidwa ntchito ndi zakumwa zolengedwa mu pharridge. Gruel - ngati hydroxyethyl cellulose amatha kuwonjezeredwa mwachindunji penti. Hydroxyethyl cellulose yadzazidwa ndi phala. Pambuyo kuwonjezera lacquer, kusungunuka nthawi yomweyo ndikukula. Pambuyo powonjezera, pitirizani kuyambitsa mpaka hydrothyl cellulose kusungunuka kwathunthu ndi yunifolomu. Porridge wamba imapangidwa posakaniza magawo asanu ndi limodzi a zosungunulira kapena madzi oundana ndi gawo limodzi la hydroxyethyl cellulose. Patatha pafupifupi mphindi 5-30, kalasi ya utotoHecHydrolyzoes ndi akuwoneka bwino. M'chilimwe, chinyezi chamadzi chimakwera kwambiri kuti chigwiritsidwe ntchito pa phala.

6 Mukamagwiritsa ntchito utoto wa utoto wautoHec, kusamwa kwa amayi mowa sikuyenera kukhala wapamwamba kuposa 2.5-3% (ndi kulemera), apo ayi Mayi amamwa mowa amavutikira.

Zinthu zomwe zikukhudzana ndi utoto wa latex

1.Kulowa kofikira kwambiri pa utoto, mawonekedwe apamwamba.

2.Kodi kuchuluka kwa ogwiritsira ntchito ndi madzi mu utoto wa utoto?

3 mu kaphatikizidwe wa latex, zotsalira zotsalira za kuchuluka kwa kuchuluka kwake.

4. Mlingo wa otsatsa ena achilengedwe mu utoto utoto ndi kuchuluka kwa kuchuluka kwa utotoHec.)

5.Kodi njira yopangira utoto, dongosolo lazinthu zowonjezera Thicker ndiloyenera.
