imyenda ya hydrophobique

Ku bijyanye na matelas, abantu bose barabamenyereye. Matelas ku isoko biroroshye kuyibona, ariko ndizera ko abantu benshi batita cyane kumyenda ya matelas. Mubyukuri, umwenda wa matelas nawo ni ikibazo kinini. Uyu munsi, umwanditsi azavuga kuri imwe murimwe, nyuma ya byose, umwenda ntushobora kuvugwa muri make mumagambo make.

Uyu munsi, umwanditsi agiye kwerekana umwenda ufite ingaruka zidafite amazimatelas.

Imyenda ya hydrophobique ni iki?

Umwenda utagira amazi - mubisanzwe, bisobanura kubuza amazi kwinjira muruhande rumwe rw'umwenda ujya kurundi. Nubwoko bushya bwimyenda yimyenda, igizwe na polymer idafite amazi kandi ihumeka (firime ya PTFE) ihujwe nigitambara gikomatanya.

Kuki ishobora kutagira amazi?

Muri iki gihe, imyenda myinshi ya matelas ntabwo irinda amazi, gusa umubare muto w’amazi wometse kuri matelas, uzayinjiramo nyuma yigihe gito, utange ubuzima bwiza bwa bagiteri na mite. Kandi kumyenda idakoresha amazi, ibintu nkibi ntibyari kuvumburwa. Ihame ryayo ni uko uko imyuka y’amazi imeze, uduce duto tw’amazi ni duto cyane, kandi dukurikije ihame ryimikorere ya capillary, barashobora kwinjira neza muri capillary kurundi ruhande, bikavamo ibintu byo gutembera. Iyo imyuka y'amazi ihurira mu bitonyanga by'amazi, ibice biba binini. Bitewe n'ubushyuhe bwo hejuru bwibitonyanga byamazi (molekile zamazi zikurura kandi zikarwanya), molekile zamazi ntizishobora gutandukana neza nigitonyanga cyamazi kandi zinjira kurundi ruhande, ibyo birinda kwinjira mumazi kandi bigatuma membrane ihumeka idafite amazi. Uwitekaimyenda idodayakozwe na Liansheng nayo igira ingaruka zidafite amazi kandi ikoreshwa cyane mugukora imifuka yimvura muri matelas. Nibihendutse kandi biramba.

Ni ibihe bintu nyamukuru biranga imyenda idakoresha amazi?

Ibikorwa by'ingenzi by'imyenda idakoresha amazi harimo kutirinda amazi, kwinjiza amazi, guhumeka, kubika, no kurwanya umuyaga. Kubijyanye na tekinoroji yumusaruro, ibisabwa bya tekiniki kumyenda idakoresha amazi kandi ihumeka irarenze cyane iy'imyenda rusange itagira amazi; Muri icyo gihe, ukurikije ubuziranenge, imyenda idakoresha amazi kandi ihumeka nayo ifite ibiranga imikorere iyindi myenda itagira amazi idafite. Imyenda idakoresha amazi kandi ihumeka ntabwo yongerera imbaraga gusa umwuka no gukomera kwamazi yigitambara, ariko kandi ifite guhumeka bidasanzwe. Barashobora kwirukana vuba imyuka y'amazi imbere yimiterere, bakirinda gukura kwifumbire, kandi umubiri wumuntu uhora wumye. Bakemura neza ibibazo byo guhumeka, kurwanya umuyaga, kwirinda amazi, nubushyuhe, bigatuma ubwoko bushya bwimyenda myiza kandi yangiza ibidukikije.

Matelas nikintu cyingenzi cyo kuryamaho mubuzima bwacu bwa buri munsi. Niba hari abana bakora cyane murugo, urashobora gutekereza kugura matelas ikozwe mumyenda idakoresha amazi kugirango ukoreshe inyuma, bishobora kugabanya ibibazo byinshi mubuzima bwawe.

Uburyo bwo kwirukana amazi

1. Inzira ya Yang

Igitonyanga cyamazi kigwa hejuru yubutaka, ukeka ko ubuso buringaniye, uburemere bwigitonyanga bwibanze kumwanya umwe, kandi umubare mumurima ntiwirengagizwa. Bitewe nubusabane hagati yubushyuhe bwo hejuru (Ys) bwa fibre mumyenda, uburemere bwubuso (YL) bwamazi, hamwe nimpagarara (YLS) yimitsi, ibitonyanga bizakora imiterere itandukanye (kuva kuri silindrike kugeza kumurongo wose). Iyo igitonyanga cyamazi kiri muburinganire hejuru yubutaka bukomeye, ingingo A ikorwa ningaruka za rukuruzi zitatanye, usibye kuringaniza byuzuye.

Inguni 0 yitwa guhuza impande, Iyo 0 = Saa kumi nimwe za mugitondo, igitonyanga cyamazi gihanagura ubuso bukomeye kuri ecran ya pamba, aribwo buryo bugarukira bwubutaka bukomeye butwarwa numurima. Iyo 0 = 1800, igitonyanga cyamazi ni silindrike, nikintu cyiza kitari amazi. Kurangiza amazi, kurangiza hejuru yigitonyanga cyamazi birashobora gufatwa nkigihe gihoraho. Kubwibyo, niba umurima ushobora guhanagura ubuso bukomeye bingana nuburemere bwa relay yikibabi cya lotus yapfuye hejuru yubutaka muri banki. Bavuga ko impande nini yo guhuza ya 0 ari nziza cyane kubitonyanga byamazi Rolling igihombo, bivuze ko bito ari byiza.

2. Akazi ko gufunga imyenda

Bitewe nuko Ys na YLS bidashobora gupimwa muburyo butaziguye, guhuza inguni 0 cyangwa cos0 mubisanzwe bikoreshwa mugusuzuma mu buryo butaziguye urwego rwo gutose. Nyamara, impande zifatika ntabwo arimpamvu yo guhanagura, kandi ibisubizo nyabyo rero nibipimo byerekana umurimo wo gufatanya no gukorana hagati yabo, kimwe nurwego rwo guhanagura.

Byombi YL na cos0, byerekana imirimo ifatika, birashobora gupimwa, bityo ikigereranyo gifite akamaro gakomeye. Mu buryo nk'ubwo, umurimo usabwa kugirango ugabanye igitonyanga cyamazi kuri buri gice cyimbere kuri interineti mo ibitonyanga bibiri ni 2YL, ishobora kwitwa umurimo uhuza amazi. Uhereye kuri formula, birashobora kugaragara ko uko imirimo yo gufatira hamwe yiyongera, impande zo guhuza zigabanuka. Iyo umurimo wo gufatanya uhwanye nakazi gahuriweho, ni ukuvuga impande zifatika ni zeru. Ibi bivuze ko amazi yatunganijwe rwose hejuru yubutaka. Kubera ko cos0 idashobora kurenga 1, niyo akazi ko gufatira hejuru kurenza 2YL, inguni yo guhuza ntigihinduka. Niba WSL = ”YL, noneho 0 ni 900. Iyo inguni yo guhuza ari 180 °, WSL = O, byerekana ko nta ngaruka zifatika ziri hagati y’amazi n’ibikomeye. Icyakora, bitewe ningaruka zimwe zifatika hagati yibi bice byombi, ibihe aho impande zingana zihwanye na 180 ° ntabwo byigeze biboneka, kandi hafi ya byose, hashobora kuboneka gusa ibintu bigereranijwe, urugero nka 160 ° cyangwa binini.

3. Ubuso bukomeye bwimyenda yimyenda

Bitewe no gupima hafi bidashoboka gupima uburemere bwubuso bukomeye, kugirango ubashe gusobanukirwa nubuso bwubuso bukomeye, umuntu yapimye uburemere bwabwo bukomeye. Nubwo ubuso bukomeye bushobora kudashobora kwerekana neza uburemere bwubuso bwibikomeye, ahubwo ni ubunini bwa Ys YLS, burashobora kwerekana ingorane zo guhanagura hejuru yikomeye. Ariko bigomba

Twabibutsa ko gupima uburemere bwubuso bukomeye nuburyo bufatika kandi intera yo gupima nayo ni nto cyane.

Birashobora kugaragara ko usibye selile, uburemere bukabije bwibintu byose bisoreshwa kugirango buke, bityo bose bafite urugero runaka rwokwirinda amazi, CF3 nini nini na CH ikaba nto. Ikigaragara ni uko intebe iyo ari yo yose ifite itumanaho rinini hamwe n’uburemere buto bwo hejuru, kimwe n’umukozi wese urangiza, bishobora kugera ku ngaruka nziza zo kurwanya amazi.
