Pakutsuka kowuma, kuyenda ndi kukhudzika kwa ma sodi kungapangitse dothi lonyansa ndi ma electostatic mphamvu zokhala ndi madontho omwe amaphatikizira ndi madontho omwe amaphatikiza zovala kuti achoke kuntchito yotsuka. Madzi ochepa ndi owonjezera mu wothandizika woyeretsa amatha kuyimitsa ndikubalalitsa tinthu tating'onoting'ono tomwe timagwera, kuzipewanso kuyikanso zovala.
(5) Zinthu zomwe zikukhudzanso mphamvu yotsuka

Adsorption Adsororption ya okonda kuphatikizika ndikuchepetsa kwa mawonekedwe (zigawo) ndizofunikira kwambiri pakuchotsa madzi kapena zinthu zolimba. Koma njira yosambitsa ndi yovuta, ndipo ngakhale kutsuka kwa mtundu womwewo kumakhudzidwa ndi zinthu zina zambiri. Izi zimaphatikizapo kuchuluka kwa zotsekemera, kutentha, chilengedwe cha dothi, mtundu wa fiber, ndi kapangidwe ka nsalu.

① Kukhazikika kwa ogwiritsa ntchito

Micrelle wa orfactonts mu yankho imagwira gawo lofunikira pakutsuka. Pamene ndende itafika pamiyeso yovuta kwambiri (CMC), kutsuka kumawonjezeka kwambiri. Chifukwa chake, kuchuluka kwa chopilira mu solvent kuyenera kukhala chapamwamba kuposa mtengo wa CMC kuti ukwaniritse bwino kutsuka bwino. Komabe, pamene kuchuluka kwa okonda kuchuluka kwa CMC, kutsuka kowonjezereka kumakhala kofunikira kwenikweni, ndipo kuchuluka kwambiri mu surtictor ndende sikofunikira.
Mukamagwiritsa ntchito mitu yochotsa mafuta, ngakhale ngati chidwi chili pamwamba pa mtengo wa cmc, solubilizetion imagwirabe ntchito ndi kuchuluka kwa chidwi cha ndende. Pakadali pano, ndikofunikira kugwiritsa ntchito zotchinga kwanuko, monga pama cuffs ndi zovomerezeka za zovala zomwe zilipo dothi zambiri. Mukatsuka, wotsetsereka amatha kugwiritsidwa ntchito koyamba kuti musinthe zosintha zaochuludzo wa orfacts.

Kutentha kumakhala ndi vuto lalikulu pakuyeretsa. Ponseponse, kukulitsa kutentha kumakhala kopindulitsa chofukizira dothi, koma nthawi zina kutentha kwambiri kumatha kuyambitsanso zovuta.

Kuchulukitsa kutentha kumakhala kopindulitsa kwa mbeu. Madontho olimba amasungunuka mosavuta ngati kutentha kumakhala pamwamba pa malo awo osungunuka, ndipo ulusiwo umawonjezera kuchuluka kwa kuchuluka kwa kuchuluka kwa kuchuluka kwa kutentha. Zinthu izi ndi zopindulitsa pakuchotsa dothi. Komabe, nsalu zolimba, micro micRs pakati pa ulusi zimachepetsedwa pambuyo pakukula kwa fiber, komwe sikuyenera kuchotsa dothi.

Kusintha kwa kutentha kumakhudzanso kusungunuka, mtengo wa cmc, ndi michere ya michenje ya okonda, potero akukhudza kutsuka. Kutalika kwa carbon banfackantss ali ndi kusungunuka kosungunuka pamatenthedwe otsika, ndipo nthawi zina amakhala osungunuka kuposa mtengo wa CMC. Poterepa, kutentha kuzizira kumayenera kukulira bwino. Mphamvu ya kutentha pa cmc mtengo ndi kukula kwa michenje ndizosiyana kwa ionic ndi ionic surfactonts. Kwa Ionic Orfactonts, kuwonjezeka kwa kutentha kumabweretsa kuwonjezeka kwa mtengo wa cmc komanso kuchepa kwa michenje. Izi zikutanthauza kuti kuchuluka kwa okonda okonda kuyenera kuchuluka pakusambitsa. Kwa osagwirizana osagwirizana, kutentha kwambiri kumabweretsa kuchepa kwa mtengo wawo wa cmc komanso kuwonjezeka kwakukulu kwa michenje yawo. Itha kuwoneka kuti kutentha koyenera kumatha kuthandiza ogwiritsa ntchito ogwiritsa ntchito ogwiritsa ntchito. Koma matenthedwe sayenera kupitilira mitambo yake.

Mwachidule, kutentha koyenera kwambiri kumakhala kokhudzana ndi njira yotsekemera ndi chinthu chotsukidwa. Zofooka zina zimakhala ndi zosintha zabwino kutentha, pomwe zofukizira zina zimakhala ndi kuyeretsa kosiyanasiyana kozizira komanso kutentha kwamoto.

③ Zitho

Anthu nthawi zambiri amasokoneza kuthekera kwa chiwopsezo chotsuka, kukhulupirira kuti zoletsa zomwe zili ndi kuthekera kwamphamvu kumakhala ndi zotsatirapo zabwino. Zotsatira zikuwonetsa kuti kutsuka sikugwirizana mwachindunji ndi kuchuluka kwa chithovu. Mwachitsanzo, pogwiritsa ntchito chotchinga chofewa chofuna kuchapa sichikhala ndi chosambitsa kwambiri kuposa chowongoletsera kwambiri.

Ngakhale chithovu sichinafanane mwachindunji kutsuka, chithovu ndi chothandizabe kuchotsa zinyalala nthawi zina. Mwachitsanzo, chithovu cha kusamba chimatha kunyamula mafuta amatsikira mukamatsuka mbale. Popanga carpet, chithovu chimathanso chochotsa tinthu tating'onoting'ono tokhala ngati fumbi. Maakaunti a fumbi chifukwa cha kuchuluka kwakukulu kwa uvet, motero oyeretsa matope amayenera kukhala ndi kuthekera kwina.

Mphamvu yolumitsa ndiyofunikanso kwa shampoo. Chikopa cha chabwino chomwe chimapangidwa ndi madzi mukatsuka tsitsi kapena kusamba kumapangitsa kuti anthu azimasuka.

Mitundu ya ulusi ndi zinthu zakuthupi

Kuphatikiza pa kapangidwe kake ka ulusi wokhudza chotsatsa ndikuchotsa dothi, maonekedwe a ulusi ndi kapangidwe ka mafupe ndi nsalu zimakhudzanso vuto la kutha kwadothi.

Masikelo a ulusi wa ubweya ndi mawonekedwe athyathyathya ngati ulusi wa thonje amakhala wokonda kucheza ndi ulusi wosalala kuposa ulusi wosalala. Mwachitsanzo, carbon wakuda adatsatira filimu ya cellulose (filimu yomatira) ndizosavuta kuchotsa, pomwe carbon wakuda adapirira nsalu thonje ndizovuta kutsuka. Mwachitsanzo, nsalu zazifupi za polyester ndizokonda kupeza madontho ochulukirapo kuposa nsalu zazitali, ndipo madontho a mafuta pa nsalu zazifupi ndizovutanso kuposa zomwe zili pa nsalu zazitali.

Zingwe zopindika zokhotakhota zolimba ndi nsalu zolimba, chifukwa cha mipata yaying'ono ya micro pakati pa ulusi, mutha kukana kulamula kwa dothi, komanso kuletsa njira yoyeretsa pochotsa dothi lamkati. Chifukwa chake, nsalu zolimba zimakhala ndi kukana kwabwino kwa dothi pa chiyambi, koma ndizovutanso kuyeretsa pomwe zidayipitsidwa.

⑤ kuuma kwamadzi

Kukhazikika kwa chitsulo monga Ca2 + ndi mg2 + m'madzi amakumana ndi mphamvu yotsuka, makamaka pamene Anionic soseckants amakumana ndi cancrombotits + ndi mg2 + ma magnesiamu mchere osauka, zomwe zingachepetse luso lawo losauka. Ngakhale kuchuluka kwa okonda kuchuluka kwa madzi okwera m'madzi olimba, kusintha kwawo kukukulirapo kwambiri kuposa distillation. Kuti mukwaniritse bwino kuchapa kwa orfactonts, ma ions a cax + mpaka 10-6mol / l (Cacol / l (1mg / l). Izi zimafuna kuwonjezera sofinenti osiyanasiyana kuti akhale wotsekemera.
