Njira yonse kuyambira ulusi mpaka kuluka ndi kupaka utoto!

Kuwotcha: Yatsani fumbi pamwamba pa nsalu kuti nsaluyo ikhale yoyera komanso yokongola, komanso pewani utoto wosagwirizana kapena zolakwika zosindikizira chifukwa cha kupezeka kwa fumbi panthawi yopaka utoto kapena kusindikiza.

Kukonza kukula: kuchotsa kukula kwa nsalu imvi ndi kuwonjezera mafuta, zofewetsa, zokhuthala, zosungira, ndi zina zotero, zomwe zimathandiza pakuphika ndi kuyeretsa pambuyo pake.

Kusungunula: kuchotsa zinthu zodetsa zachilengedwe mu nsalu zotuwa monga sera, pectin, nayitrogeni ndi mafuta ena, ndi zina zotero, kotero kuti nsaluyo ikhale ndi madzi okwanira, zomwe zimathandiza kuti utoto ulowerere komanso kufalikira panthawi yosindikiza ndi kuyika utoto.

Kuyeretsa: kuchotsa utoto wachilengedwe pa ulusi ndi zinthu zodetsa monga makoko a mbewu za thonje, kupatsa nsalu kuyera kofunikira, ndikuwonjezera kuwala ndi mphamvu ya utoto.

Kusakaniza: Kudzera mu mankhwala a soda yosungunuka, kukula kokhazikika, kunyezimira kolimba komanso mphamvu yabwino yothira utoto zimapezeka, ndipo zinthu zakuthupi ndi zamakaniko monga mphamvu, kutalika ndi kusinthasintha zimawonjezeka.

2. Mitundu ya utoto womwe umagwiritsidwa ntchito kwambiri

Utoto wolunjika: Utoto wolunjika umatanthauza utoto womwe ungatenthedwe ndikuwiritsidwa mu sing'anga yopanda mpweya kapena ya alkaline pang'ono kuti upange utoto wa thonje mwachindunji. Uli ndi mawonekedwe olunjika kwambiri ku ulusi wa cellulose, ndipo sikofunikira kugwiritsa ntchito utoto wokhudzana ndi njira zamankhwala ku ulusi wa utoto ndi zinthu zina.

Utoto wochita zinthu mopupuluma: Ndi utoto wosungunuka m'madzi wokhala ndi magulu ogwira ntchito mu molekyulu, womwe ungagwirizane bwino ndi magulu a hydroxyl pa mamolekyu a cellulose pansi pa mikhalidwe yofooka ya alkaline. Kuthamanga kwa utoto wochita zinthu mopupuluma nthawi zambiri kumakhala bwino masana. Pambuyo potsuka ndi kuyandama kwathunthu, kulimba kwa sopo ndi kupukuta kumakhala kwakukulu.

Utoto wa asidi: Ndi mtundu wa utoto wosungunuka m'madzi wokhala ndi magulu a asidi m'mapangidwe ake, omwe amapakidwa utoto mu asidi. Utoto wambiri wa asidi uli ndi sodium sulfonate, wosungunuka m'madzi, wowala bwino komanso wodzaza ndi mitundu. Umagwiritsidwa ntchito makamaka popaka utoto wa ubweya, silika ndi nayiloni, ndi zina zotero. Ulibe mphamvu yopaka utoto ku ulusi wa cellulose.

Utoto wa Vat: Utoto wa Vat susungunuka m'madzi. Mukapaka utoto, uyenera kuchepetsedwa ndikusungunuka mu yankho lamphamvu la alkaline kuti upange mchere wa leuco-chromatic sodium ku ulusi wa utoto. Pambuyo pa okosijeni, umabwerera kumadzi a utoto wosasungunuka ndikuuyika pa ulusi. Nthawi zambiri umatha kutsukidwa, kupepuka kumakhala kolimba.

Utoto Wothira Utoto: Utoto wothira Utoto uli ndi mamolekyu ang'onoang'ono ndipo suli ndi magulu osungunuka m'madzi m'kapangidwe kake. Umathira utoto wofanana mu njira yothira utoto pogwiritsa ntchito zothira utoto. Thonje la polyester lopakidwa utoto ndi utoto wothira utoto likhoza kukhala ulusi wa polyester wopakidwa utoto, ulusi wa acetate ndi ulusi wa polyester amine, ndipo umakhala utoto wapadera wa polyester.
