Kugwiritsa ntchito hydroxyethyl cellulose mu utoto wa mochedwa

Hydroxyethyl cellulose (hec)ndi ma cellulose osungunuka madzi osungunuka ndi makulidwe abwino, kupanga filimu, kunyowa, kukhazikika, ndi kutulutsa zinthu. Chifukwa chake, imagwiritsidwa ntchito kwambiri m'minda yambiri ya mafakitale, makamaka imagwira ntchito yofunika kwambiri komanso yofunika kwambiri mu utoto wa latex (yemwe amadziwikanso ngati utoto wozikidwa m'madzi).

1. Zoyambira zoyambira za hydroxyethyl cellulose
Hydroxyethyl cellulose ndi mankhwala osungunuka madzi pompona ndi mamolekyulu osinthika a cellulose (kuyambitsa hydroxyethyl magulu a mamolekyulu a cellulose). Zinthu zake zazikulu zimaphatikizapo:

Kusungunuka kwamadzi: Hec imatha kusungunuka m'madzi kuti apange njira yothetsera vuto lalikulu, potero kukonza zinthu zopanda pake za zokutira.
Kukula kwa kukula: Hec imatha kuwonjezera mafayilo a utoto, utoto wa mochedwa umakhala ndi zokutira bwino.
Kutsanzira ndi mawonekedwe a makanema: mamolekyu a HeC ali ndi hydrophilicity ina ya hydrophilicity, yomwe imatha kukonza magwiridwe antchito ndikupanga ma yunifolomu mogwirizana komanso osalala.
Kukhazikika: Hec ali ndi kukhazikika kwa matenthedwe ndi kukhazikika kwamankhwala, kumatha kukhala kokhazikika pakupanga ndikusunga kwa zokutira, ndipo sikukonda kuwonongeka.
Kulimbana Bwino: Hec ali ndi kukana kwakukulu, komwe kungachepetse pa utoto wa utoto pomanga ndikuwongolera zomangamanga.

2. Udindo wa hydroxyethyl cellulose mu utoto wa mochedwa
Utoto wa mochedwax ndi utoto wamadzi womwe umagwiritsa ntchito madzi ngati zosungunulira ndi polime emulsion ngati chinthu chachikulu chopanga filimu. Ndi chilengedwe chochezeka, osawakhumudwitsa, osakwiya komanso oyenera kupaka utoto wam'mbali ndi kunja. Kuphatikiza kwa hydroxyethyl cellulose imatha kusintha magwiridwe antchito a latex, omwe amawonetsedwa mwachindunji pazinthu zotsatirazi:

2.1 kukula
Mu mawonekedwe a utoto wa mapepala, hec imagwiritsidwa ntchito ngati thicker. Chifukwa cha kuchuluka kwa hec, imatha kusungunuka mwachangu m'matumbo am'madzi ndikupanga ma netiweki kudzera munthawi yolumikizirana, ndikuwonjezera mafayilo a utoto wa latex. Izi sizingathe kusintha kufalikira kwa utoto, kumapangitsa kuti akhale woyenera kutsuka, komanso kulepheretsa utoto kuti usatulutse chifukwa cha utoto wopaka utoto.

2.2 Sinthani magwiridwe antchito
HecItha kusintha zinthu mosamala za utoto wa mochedwa Kuphatikiza apo, Hec imatha kusintha kunyowa kwa utoto, kulola kupaka utoto wa mochedwa kuti kuphimba pansi mwachangu popaka utoto, kuchepetsa zilema zomwe sizingatheke.

2.3 Kusungunuka kwamadzi ndikupitilira nthawi yotseguka
Monga polymer pofini ndi mphamvu yamphamvu yosungirako madzi, hec imatha kukulitsa nthawi yotsegulira utoto wa latex. Nthawi yotsegulira imatanthauza nthawi yomwe utoto umakhalabe m'malo opaka utoto. Kuphatikiza kwa Hec kumatha kuchepetsa madzi, potero kumapereka nthawi yogwira ntchito ya utoto, kulola kuti ogwira ntchito omanga akhale ndi nthawi yambiri yopatutsa komanso yokutidwa. Izi ndizofunikira pakugwiritsa ntchito utoto wosalala, makamaka popaka madera akuluakulu, kuteteza utoto wopaka utoto mwachangu, zomwe zimapangitsa kuphika kapena kuphatikizika.

2.4 Sinthani zomatira zomatira ndi kukana madzi
Mu phula la penti ya kumapetox, hec imatha kukulitsa kutsatira pakati pa utoto ndi pamwamba pake kuti zitsimikizire kuti zokutidwazo sizimatha. Nthawi yomweyo, hec imawongolera magwiridwe antchito a latex, makamaka munyezi chinyontho, chomwe chimatha kupewa kulowa chinyezi ndikuwonjezera moyo wautumiki wokutira. Kuphatikiza apo, hydrophilicity ndi zomatira za hec zimathandizira utoto wa latx kuti apange zokutira zabwino m'malo osiyanasiyana.

2.5 Sinthani Kulimbana ndi Kulimbana
Popeza zigawo zozikika mu utoto wa latch ndizosavuta kukhazikika, zomwe zimapangitsa kuti utoto, hec, ngati wokulirapo, amatha kusintha bwino zinthu zomwe antiwoni. Pokulitsa mafati okutirawo, Hec amathandizira tinthu tokhazikika kuti zitheke kwambiri pakukutira mogwirizana, kuchepetsa tinthu, potero kusungabe kukhazikika kwa chimbudzi, potero kukonzanso kukhazikika kwa zokutira ndi kugwiritsa ntchito.

3. Ubwino wa ntchito ya hydroxethyl cellulose mu utoto wa mochedwa
Kuphatikiza kwa hydroxyethyl cellulose imakhala ndi zabwino zopangira ndikugwiritsa ntchito utoto wa latex. Choyamba, Hec ali ndi chikhalidwe chabwino zachilengedwe. Kusungunuka kwamadzi ndi kusala kwake komwe kumatsimikizira kuti utoto wa matex sikungatulutse zinthu zovulaza pakugwiritsa ntchito ma penti amakono achilengedwe. Kachiwiri, Hec ali ndi mphamvu yopanga mafilimu, omwe amatha kusintha utoto wa mafilimu a latex, ndikupanga zokutira zokutira komanso mosamalitsa, ndi kulimba kwabwino komanso kuwonongeka kwa chiwongola dzanja. Kuphatikiza apo, Hec imatha kukonza madzi ndi kugwirira ntchito utoto wa latex, kuchepetsa zovuta zomanga, ndikusintha ntchito.

Kugwiritsa ntchitohydroxyethyl celluloseMu utoto wa mochedwa Ndi kusintha mosalekeza kwa chitetezo cha chilengedwe ndikugwiritsa ntchito utoto wa utoto, hec, monga lofunika kwambiri komanso labwinobwino, lakhala imodzi mwazowonjezera zowonjezera pa utoto wamakono wa latex. M'tsogolomu, pokonza ukadaulo, kugwiritsa ntchito Hec mu utoto wa mochedwa kudzakulitsidwa ndipo kuthekera kwake kudzakhala kokulirapo.
