Hec yopaka utoto

Hec ndifupifupi kwa hydroxyethyl cellulose. Hydroxyethyl celluloseHecndi loyera kapena lofiirira lachikasu, lopanda pake, lopanda zotupa kapena lowdery lolimba la alkalinine cellulose ndi ethylene oxide (kapena chlororoethal). Ndiwosakhazikika pa cellulose ether. Monga osakhala ochepera, kuwonjezera pa kukula, kuyimitsidwa, kugwirizira, kuyandama, mawonekedwe filimu, kusungidwa, kusulitsidwa madzi, kusulitsidwa kwamadzi ndi chitetezo.

Mankhala Mawonekedwe:

1.

2, zomwe sizimagwirizana ndi ma poizoni osiyanasiyana osungunuka ndi madzi, mafuta opha, mchere, ndi wabwino kwambiri wa cololoidal wokhala ndi chidwi chachikulu cha electrolyte;

3, kuchuluka kwa madzi ndikukwera kawiri kuposa Methyl cellulose, ndikusintha bwino,

4. Hec ali ndi luso lalikulu lomwe labala lomwe limayerekezedwa ndi methyl cellulose ndi hydroxypropyl methyl celyiluse, koma luso loteteza la Coloid kwambiri.

Chifukwa chake, ma hydroxyethyl cellulose amagwiritsidwa ntchito kwambiri kuzunzidwa, ndikugwirizana, zomanga, mankhwala ndi chakudya, nsalu, kupanga ma polymerization a ma polymerization.

Zazikulu zaHecutoto wa latex

1.Katundu wambiri

Hydroxyethyl cellulose (hec) ndi yosangalatsa yophimbira ndi zodzoladzola. Pogwiritsa ntchito, kuphatikiza kwa kukula kwake ndikuyimitsidwa, chitetezo, chobalalitsa ndi kusungidwa kwamadzi kudzabala zotsatira zabwino.

1. pseudoplastic

Pseudoplastity ndi malo omwe mamasukidwe yankho amachepetsa ndikuwonjezeka kwa liwiro lozungulira. Hec yokhala ndi utoto wa latx ndiosavuta kugwiritsa ntchito burashi kapena wodzigudubuza ndipo amatha kuwonjezera mawonekedwe a pamwamba, omwe amathanso kuwonjezera ntchitoyi; Hec-yokhala ndi shampoos ndi madzimadzi ndi omata, osungunuka mosavuta komanso obalalika mosavuta.

1. Kukaniza Mchere

Hec ndi wokhazikika m'matumba omwe amakhala ndi mchere ndipo samawola ku Ionic States. Kugwiritsidwa ntchito pokwerera pamagetsi, kumatha kupangitsa kuti odulira atuluke kwambiri, owala kwambiri. Chosangalatsa kwambiri ndi kugwiritsa ntchito kwa borate, sluete ndi carbobonate a penti, amakhalabe ndi chidwi kwambiri.

4.Chiberekero

Mapangidwe a membrane mapangidwe a Hec akhoza kugwiritsidwa ntchito m'mafakitale ambiri. Pazomwe zimapangidwa ndi mapepala, zokutira za hec glazz, zitha kuteteza kulowerera kwa mafuta, ndipo itha kugwiritsidwa ntchito kukonza zina mwa njira yopangira mapepala; Hec imachulukitsa kwambiri ulusiwo panthawi yoluka komanso imachepetsa kuwonongeka kwamakina kwa iwo. Hec amachita ngati filimu yoteteza kwakanthawi nthawi yoikika ndi kupaka nsalu ndipo imatha kutsukidwa ndi nsalu ndi madzi pomwe chitetezo chake sichikufunika.

1. Kusungidwa kwamadzi

Hec imathandizira kusunga chinyezi cha dongosololi m'malo abwino. Chifukwa gawo laling'ono la hec mu njira yothetsera matendawa imatha kukwaniritsa madzi abwinoko, kotero kuti dongosololi limachepetsa kufunikira kwa madzi pokonzekera. Popanda kusungidwa kwamadzi ndi kutsatira, matope a simenti amachepetsa mphamvu ndi kutsatira, ndipo dongo lidzachepetsa chipolopolo.

Njira yogwiritsira ntchito hydroxyethyl cellulose Hecmu utoto wa mochedwa

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 okonzeka ndi amayi amadzimadzi oyembekezera: Njirayi imakhala ndi zida zapamwamba kwambiri zamadzimadzi, kenako kuwonjezera pa utoto wa latx, ubwino wa njirayi ndikusinthika kwakukulu, koma kuyenera kuwonjezeredwa mwachindunji kupanga zinthu zomalizidwa, koma ziyenera kukhala zosungidwa zoyenera. 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, hydroxyethyl cellulose hydrolyzoes komanso akuwoneka bwino. M'chilimwe, chinyezi chamadzi chimakwera kwambiri kuti chigwiritsidwe ntchito pa phala.

4.Zinthu zomwe zimafunikira chisamaliro pokonzekera hydroththyl cellulose mowa

Popeza hydroxyethyl cellulose ndi ufa wa granalar, ndizosavuta kusamalira madzi ndi njira zotsatirazi.

Chilangizo

4.1 kale ndi mutatha kuwonjezera hydroxyethyl cellulose, iyenera kusunthidwa mosalekeza mpaka yankho likaonekera kwathunthu.

4.2. Osawonjezera mu thanki yosakanikirana kwambiri kapena mwachindunji mu zochuluka kapena zowoneka bwino hydrothyl cellulose.

4.3 Kutentha kwa madzi ndi mtengo wamadzi kumawonekera ubale ku kusungunuka kwa hydrothyl cellulose, chidwi chapadera chiyenera kulipiridwa kwa icho.

4.4Osamawonjezera chinthu choyambira ku osakaniza pamaso hydroththyl cellulose ufa umanyowa ndi madzi. Kukweza p

4.5 Monga momwe tingathere, kuwonjezera koyambirira kwa milyew choletsa.

4.6 Mukamagwiritsa ntchito ma visctkerm yayitali hydroxethyl cellulose, kuchuluka kwa mayi mowa sikuyenera kukhala kwakukulu kuposa 2.5-3% (mwakulemera), apo ayi.

Zinthu zomwe zikukhudzana ndi utoto wa latex

1 Mabatani otsalira otsalira apa 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 okutira zachilengedwe zachilengedwe mu utoto wa utoto ndi kuchuluka kwaHechydroxyethyl cellulose.)

5 Pakupanga utoto, dongosolo lazinthu zowonjezera Thicker ndiloyenera.

6 Chifukwa cha kusokonekera kwambiri komanso chinyezi chochuluka pakubalalitsa.

7 Kusintha kwachilengedwe kwa Thicker.
