Ndi mitundu yanji ya otuwa omwe alipo mumawu ochokera m'madzi?

Utoto wozikidwa m'madzi umatanthauza mtundu wa utoto womwe umagwiritsa ntchito madzi ngati zosungunulira kapena kufalikira sing'anga. Utoto wopangidwa ndi madzi wakhala chitsogozo chamtsogolo cha utoto chifukwa cha kusala kwake, kosavuta kuyeretsa, mtengo wotsika, wopanda mawonekedwe, komanso osakwiya. Zojambulajambula zojambulidwa zimagwiritsidwa ntchito pang'ono popaka utoto wochokera m'madzi, koma zimatha kusintha ma utoto ndipo asanduka chopondera.Otsatsandi zowonjezera zomwe sizingafanane penti ndikupewera kusamba pakumanga, komanso perekani utoto wabwino kwambiri komanso kusungulumwa. Pautoto wochokera m'madzi wokhala ndi mafayilo otsika, ndi mtundu wofunikira kwambiri wazowonjezera.

Matumba ozungulira madzi amatha kusintha zotanga za chinyengo ndikuthandizira kukonza ma penti. Mitengo yayikulu ikagwiritsidwa ntchito, utoto umatha kupakazidwa mosavuta, ndipo akamagona akaimitsidwa kapena kukakamiza kotsika kumayikidwa, utoto umatha kukhazikikanso. Mikhalidwe iyi ikhoza, kumbali imodzi, kukonza kusungunuka kwa utoto ndikupewa kuwonongeka kwa utoto ndi mafilimu. Nthawi yomweyo, panthawi yothira mankhwalawa, amathandizira kudzoza kwa utoto wamadzi. Komabe, panthawi yomanga, amatha kuletsa kusanja kwa utoto ndikuwonetsetsa kuti utoto umagwira bwino ntchito.

Tiyeni tiwone mawonekedwe a otsatsa osiyanasiyana.

1. Matumba a celluse

LeraotsatsaKhalani ndi luso lalikulu, makamaka pakukula kwa gawo lamadzi. Ali ndi zoletsa zochepa pakupanga mafinya komanso mabulo osiyanasiyana. Komabe, ali ndi zovuta zina, monga momwe amakhalira osauka, akuwaza kwambiri panthawi yopanda roller, komanso kuwonongeka kwa kuchepa kwa microbial. Popeza ali ndi mafakisoni otsika pansi pamahatchi ambiri komanso ubweya wambiri pansi pa shear komanso wotsika pang'ono, maskecke amawonjezeka kwambiri atakutira, zomwe zingalepheretse kusagwako, koma, kumayambitsa kusamba. Ma Traulose Otsatsa a cellulose ali ndi ma shalecular yambiri, choncho amakonda. Ndipo chifukwa cellulose ili ndi hydrophilicity yabwino, imachepetsa madzi ojambula pa utoto.

2. Kuyanjana kwa poldurethane

Kapangidwe kake ka mgwirizano wa polyiretharane kumawonongedwa pansi pa ntchito yoseketsa, ndipo mafayilo amachepetsedwa. Gulu lankhondo litasowa, ma viruyo amathanso kubwezeretsedwanso popewa kusamba. Ndipo kuchira kwa Askichat kuli ndi Hysteresis wina, komwe kumapangitsa kuti azikhala ndi filimu yokutidwa ndi yokutidwa. Kuchulukitsa kwa kambiri wa polereurethane kukulira kwamitundu kuli kotsika kwambiri kuposa mitundu iwiri yoyamba ya otuwa, ndipo sikuthandizira kuwawa. Mamolekyu a Polyurethanene ali ndi hydrophilic ndi magulu a hydrophobic. Magulu a hydrophobic ali ndi ubale wolimba ndi matrix a filimu yokutira, yomwe imatha kukulitsa madzi osakanikirana.

Chifukwa chakuti tinthu tating'onoting'ono titenga nawo mbali pa mayanjano, popanda kuwononga, zomwe zimapangitsa kuti mafilimuwo azikhala osalala ndipo ali ndi gloss yapamwamba. Katundu wa kuphatikiza polyirethane amakula bwino kuposa masamba ena, koma chifukwa cha mankhwala ake okumbika, zinthu zomwe zimapangitsa michere, zigawo zikuluzikulu zomwe zimakhudza micleles mu njira yolumikizira katundu. Mukamagwiritsa ntchito mtundu uwu wa thickener, kutengera zinthu zosiyanasiyana zomwe zimapangitsa kuti zitheke zichitike. Osamasinthitsa emulsion, denomer, wobalalitsa, thandizo lopanga mafilimu, etc. ntchito pokutidwa.

Qingdao Fumaisi Wamkulu-Tech Toarts CO., LTD. Anzake pakupanga osiyanasiyanaotsatsa. Kampaniyo yagwirizana ndi lingaliro la kasamalidwe ka zaka zambiri, ndipo amayesetsa kupereka makasitomala ndi ntchito zodalirika komanso ntchito yabwino!
