Isihlabathi hydrophobic. Ukusungulwa, okuzokwenza ugcine isintu

Minyaka yonke e die ezweni cishe abantu abayizigidi ezingu-isigamu ngenxa yokuntuleka kwamanzi ahlanzekile efanelekayo ukudliwa abantu. Lokhu kwenzeka ngenxa yokuthi angaphezu kuka-80% wabo bonke amanzi uya ukuze nginisele umhlaba ezindaweni ehlane planethi. Ososayensi base-inkampani wahlanganyela ukuthuthukiswa izinto hydrophobic, owasungula le isihlabathi camera ukunciphisa isidingo yayo ngoba amanzi kanye neensetjenziswa. amazwe ase-Afrika, kanye amazwe Middle East abahlukumezeka kakhulu ngenxa yokuntuleka kwamanzi ahlanzekile okuphuza, yingakho e-United Arab Emirates, kodwa ngokusekelwa ochwepheshe isiJalimane, futhi yasungulwa ngumuntu isihlabathi hydrophobic.

Ukuze uzwisise ukuthi yayiyini, kubalulekile ukuba uhlole incazelo hydrophobicity.

Uyini hydrophobicity futhi ihluke kanjani kusukela hydrophilic?

Lezi imiqondo ezimbili ezihlobene zisebenza kunoma izinto futhi izinto. Bona banesibopho sokuqinisekisa, kuze kufike abawona lula kakhulu noma mbeni amanzi. On izinto ngenhloso ngaphandle hydrophilic ka lamanzi elulela futhi egxile ngokuphelele. Lemigwamanda zihlanganisa carbonates, silicates, sulfate, ubumba kanye ingilazi silicate. A ebusweni hydrophobic okucasulayo amanzi iconsi futhi ulunika ukuhlaba zingene ngaphakathi. Le mpahla unolwazi zonke izinsimbi, waxes, amafutha, waxes, kanti ezinye izinhlobo Plastics. Hydrophobicity - ngezinga eliphansi hydrophilicity. Basembonini yendwangu is phansi hydrophilization Indwangu ukuba ngcono wamelana staining, hydrophobicity babo bunomthelela akunika impermeability.

Indlela yokuvimbela izakhiwo hydrophilic zasesihlabathini?

Ngisho ngaphandle engena phakathi izinto kakhulu physics, kuyaqondakala ukuthi kahle isihlabathi kukuvumela futhi ubamba amanzi. Kodwa sibonga nanotechnology yesimanje, ososayensi angenza izimanga, ekushintsheni izakhiwo yokuqala izinto. Ukuze bathole isihlabathi hydrophobic, babefanele ukucubungula uhlamvu lwenhlabathi ngamunye isixazululo ekhethekile, izimfihlo zazo hhayi wachazela. isihlabathi okunjalo azigcina impahla yayo iminyaka engu-30. Kuze kube manje, le misebenzi zenzeke ezingeni kokwazi, kodwa inkampani uzimisele ukusebenza ngezinga ezimbonini. Ukuze ucubungule okusanhlamvu elilodwa isihlabathi, kuthatha imizuzwana-40, kodwa abakhiqizi babe nezinto ukukhiqiza isihlabathi hydrophobic nsuku zonke inani amathani 3,000.

Njengoba isihlabathi kuzonciphisa ukusetshenziswa global yamanzi?

Ososayensi ukuphakamisa usebenzisa isihlabathi hydrophobic endaweni amanzi angangeni ngokwahlukana ungqimba phakathi inhlabathi evundile lapho izitshalo, kanye nazo zonke ezinye kwezakhi zenhlabathi. Lesi sendlalelo kuzonciphisa isibalo irrigations ngelanga, izikhathi 5 komunye, ngoba amanzi ngeke ukuya ukujula okondliwa kulo izimpande. Ososayensi baye banquma ngisho ukuhlola ngokugqamile yokutshala irayisi ezindaweni ezomile, kodwa akukho imiphumela ukhonkolo okwamanje.

Sand nge izakhiwo hydrophobic umthole omunye ukusetshenziswa ekwakheni futhi ekwakhiweni izisekelo, ikakhulukazi ezindaweni amazinga aphezulu komhlaba.

Kanjani ukwenza isihlabathi hydrophobic kakhulu?

Ukubeka nedlanzana isihlabathi emanzini, bese kukhishwe khona therefrom ezomile, kubalulekile ukwenza pretreatment, ngokuvamile besebenzisa organosilicon polymers. Iningi lengubo izingqondo is haunted by umbuzo: kungenzeka ukwenza isihlabathi hydrophobic ekhaya? Yiqiniso, kungenzeka, kodwa hhayi eliphezulu okunjalo futhi eside azigcina impahla yayo. Kukhona enye indlela abanye abantu ukukhombisa umphakathi ukuthi ukugxila. Kuyadingeka ukuba wafaka ashisayo kuhhavini isihlabathi ahlanzekile, kukhona ukuba amnike efudumele ezinhle futhi yome out. Bese-ke futhi aphathe amanzi-oxosha izifutho ufuna izingubo zokugqoka. Thenga labo etholakalayo nganoma iyiphi esitolo kwezemidlalo. Ngemva manipulation idatha kungenziwa kaningi ukubeka futhi uthole isihlabathi aphume ethangini lamanzi wawusomile.
