Kuyambitsa kuyambitsa kwa cellulose

Utoto wa latex ndi utoto wosakaniza, kufalikira kwa mafilimu ndi ma filler obala, ndipo zowonjezera ziyenera kugwiritsidwa ntchito kusintha mawonekedwe ake kuti azikhala ndi zinthu zilizonse zosewerera, zosungirako. Zowonjezera ngati zoterezi nthawi zambiri zimatchedwa olima, zomwe zimatha kuwonjezera mafayilo ndikuwongolera zokutira, choncho zimatchedwanso obzala zipatso.

Izi zimangoyambitsa mikhalidwe yayikulu yomwe anthu ambiri amagwiritsa ntchito ma cellulose omaliza ndi kugwiritsa ntchito kwawo mumawu oluka.
Zipangizo zama celluloosic zomwe zitha kugwiritsidwa ntchito kupangira methyl cellulose, hydroxthyl cellulose, ndi hydroxypropyl methyl celyiluse. Mbali yayikulu kwambiri ya cellulose ndikuti zotsatira zake zimakhala zodabwitsa, ndipo zimatha kupatsa utoto madzi, omwe amatha kuchedwetsa nthawi yowumayo, ndikupanganso utoto kukhala ndi chithunzi china, kupewa utoto wina kuti usafota. Kusakhalitsa ndi Kubalira Pakusungirako, otuwawa amakhalanso ndi vuto la maulendo ovala utoto, makamaka akamagwiritsa ntchito mafayilo apamwamba.

Cellulose ndi mankhwala osokoneza bongo, motero anti -beni ayenera kulimbikitsidwa mukamagwiritsa ntchito. Ma Trauluosic Otsatsa Madzi, koma osakhumudwitsa ena mu utoto wopangidwa ndi utoto wa utoto ndi utoto wa kuwonekera (kawirikawiri ngati Ku Visncle).

1. Hydroxyethyl cellulose

Zolemba ndi mitundu ya hydroxethyl cellulose imasiyanitsidwa makamaka malinga ndi kuchuluka kwa zolowa m'malo mwake. Kuphatikiza pa kusiyana kwa mafakisoni, mitundu ya hydroxethyl cellulose imatha kugawidwa mu mtundu wazobowoleza wosungunuka, mtundu wodetsa nkhawa komanso mtundu wazokhazikika kudzera pakusintha. Ponena za njira yogwiritsira ntchito, hydroxyethyl cellulose imatha kuwonjezeredwa pamagawo osiyanasiyana pakupanga zokutira. Mtundu wobalalika msanga umatha kuwonjezeredwa mwachindunji mu mawonekedwe a ufa wowuma, koma mtengo wa pH musanawonjezere kuti isasungunuke mkati mwa tinthu tating'onoting'ono, kenako ndikuwonjezera mtengo wa mabulu kuti asungunuke mwachangu. Njira zofananira zingagwiritsidwenso ntchito kukonza guluu ndi kuwonjeza pa utoto.

2. Hydroxypropyll methyl cellulose

Mphamvu yakukula kwa hydroxypylropyl ndizofanana ndi za hydroxenulose, ndiye kuti, kuwonjezera mamasukidwe okutira ku mitengo yotsika komanso ya sing'anga. Hydroxypypyl a methylcellulose amawonongeka ndi enzymatic kuwonongeka, koma kusungunuka kwamadzi sizabwino monga za hydroxethyl cellulose, ndipo zimakhala ndi zovuta zogulira. Kwa Hydroxypypypyl methylcelulose, imatha kuwonjezeredwa mwachindunji ndi kusunthidwa ndikubalalitsa, kuwonjezera zinthu zamchere monga 8-9, ndikuyambitsa mpaka utasungunuka mpaka atasungunuka kwathunthu. Kwa hydroxypropyl methylcellulose popanda chithandizo, imatha kunyowa ndi madzi otentha pamwamba pa 85 ° C asanagwiritsidwe, kenako ndikukakamizidwa ndi madzi ozizira kapena madzi oundana kuti asungunuke kwathunthu.

3. Methyl cellulose

Methylcellulose imakhala ndi zofananira ku hydroxypropropylmethylcelulose, koma sizingakhale zokhazikika pakuwoneka kutentha.

Hydroxyethyl cellulose ndiye thialose kwambiri mu utoto wa mochedwa Chogwiritsidwa ntchito kwambiri pakukula kwa utoto wamba wa latx, imvi ya imvi ya calky, ndi zina zachiwiri ndi hydroxygyllulose, zomwe zimagwiritsidwanso ntchito kuchuluka kwa opanga. Pathyl cellulose sigwiritsidwa ntchito muutoto wa lambi wa lambi, koma imagwiritsidwa ntchito kwambiri mu khomo lamkati lamkati komanso lakunja chifukwa cha kusungunuka kwapakatikati komanso kusungunuka kwamadzi. Chuma chachikulu cha mavicyl cellulose amatha kutulutsa putty ndi kusungidwa kwaphokoso kwambiri komanso kusungidwa kwamadzi, kumapangitsa kuti zikhale ndi katundu wabwino.
