Putos slopinimo med\u017eiaga veikia tik tada, kai skystis jos visi\u0161kai ne\u012fsisavina. Tai skamba keistai, kol nepamatysi ne gatavo produkto skardin\u0117s, o put\u0173 pl\u0117vel\u0117s. \u0160iuos produktus vertinu pagal vien\u0105 po\u017eym\u012f: plon\u0105 sienel\u0119 tarp dviej\u0173 burbuliuk\u0173. Jei priedas lieka i\u0161tirp\u0119s skys\u010dio mas\u0117je, jis niekada nepasiekia tos sienel\u0117s. Jei jis smarkiai atstumiamas, susidaro la\u0161eliai ir lieka \u012fdubos. Naudingos r\u016b\u0161ys yra tame siaurame tarpsnyje tarp \u0161i\u0173 dviej\u0173 nes\u0117kmi\u0173.<\/p>\n
Putos i\u0161lieka, nes pavir\u0161inio aktyvumo med\u017eiagos susikaupia oro ir vandens s\u0105sajoje ir i\u0161laiko pl\u0117vel\u0119 elasting\u0105. Oras nuolat patenka i\u0161 tirpiklio disko, siurblio, purk\u0161tuvo arba aeracijos baseino. Antiput\u0173 la\u0161elis turi patekti \u012f t\u0105 pl\u0117vel\u0119, pasklisti po j\u0105 ir palikti silpn\u0105 tiltel\u012f, kad skystis nutek\u0117t\u0173, o burbulas suskilt\u0173. Norint, kad med\u017eiaga \u012fsiskverbt\u0173 ir pasiskirstyt\u0173, jos pavir\u0161iaus \u012ftempimas turi b\u016bti ma\u017eesnis nei putojan\u010dio skys\u010dio, o tirpumas jame \u2013 menkas. \u0160tai ir visa paslaptis. Polidimetilsiloksano pavir\u0161iaus \u012ftempimas vandens at\u017evilgiu yra apie 20 mN\/m, o vandens \u2013 72 mN\/m, tod\u0117l jis sunkiai pasiskirsto. Hidrofobinis silikatas daugelyje emulsij\u0173 veikia kaip smeigtukas ir u\u017ebaigia pl\u0117vel\u0117s ply\u0161im\u0105. Mineralin\u0117s alyvos put\u0173 slopintuvas su hidrofobin\u0117mis dalel\u0117mis atlieka t\u0105 pa\u010di\u0105 u\u017eduot\u012f, tik l\u0117\u010diau. Polieteriniai preparatai da\u017enai priklauso nuo temperat\u016bros: \u0161altame ore jie veikia ramiau, netenka tirpumo art\u0117jant prie drumstumo ta\u0161ko ir tik tada u\u017eima s\u0105saj\u0105.<\/p>\n
Laboratoriniai indai tai paslepia. Purtymo bandymas vertina greit\u0105 put\u0173 slopinim\u0105. Cirkuliacin\u0117 linija vertina la\u0161elius, kurie i\u0161lieka po \u0161lyties, kaitinimo ir visos dienos pumpavimo. Per didelis emulsiklio kiekis daro put\u0173 slopintuv\u0105 \u201cgra\u017e\u0173\u201d formul\u0117je, bet nenauding\u0105 pa\u010dioms putoms. Jei jo per ma\u017eai arba naudojamas netinkamas silikonas, i\u0161d\u017ei\u016bvusi danga tampa \u201e\u017euvies akimis\u201c, atsiranda riebus drumstumas arba ant jos ne\u012fsigeria naujas sluoksnis. T\u0105 pa\u010di\u0105 savait\u0119, naudodamas t\u0105 pa\u010di\u0105 derv\u0173 sistem\u0105, susid\u016briau su abiem \u0161iais defektais. Doz\u0117 beveik nesikeit\u0117. Pasikeit\u0117 suderinamumas.<\/p>\n
B\u016btent tod\u0117l a\u0161 skirstau priedus, naudojamus vandens pagrindo dangose. Viena dalis patenka \u012f malimo proces\u0105, nes mal\u016bnas sukuria oro sraut\u0105 ir taip pat susmulkina stambias la\u0161eli\u0173 daleles iki dyd\u017eio, su kuriuo pl\u0117vel\u0117 gali susidoroti. Kita dalis patenka \u012f skiedimo proces\u0105, kad sugaut\u0173 mikroput\u0105, kuri atsiranda tik tada, kai klampumas pradeda did\u0117ti. Viena v\u0117lyva med\u017eiagos doz\u0117 popieriuje atrodo veiksminga. Ji u\u017erakina ma\u017eus burbuliukus kiet\u0117jan\u010dioje pl\u0117vel\u0117je. Su technologiniu vandeniu taikoma ta pati id\u0117ja, tik naudojant kitus \u012frenginius: pastovus keli\u0173 de\u0161im\u010di\u0173 ppm kiekis paprastai yra geriau nei panikos apimtas i\u0161pylimas \u012f putojimo rezervuar\u0105.<\/p>\n
Kai po valandos cirkuliacijos i\u0161liekamumas i\u0161nyksta, a\u0161 i\u0161 prad\u017ei\u0173 nedidinau doz\u0117s. A\u0161 klausiu, ar hidrofobin\u0117 med\u017eiaga buvo suskaidyta iki suderinamo pavidalo, ar pH sutrikd\u0117 emulsij\u0105, ar preparatas buvo sukurtas tik pavir\u0161iaus putoms pa\u0161alinti, o ne mikroputoms, esan\u010dioms mas\u0117je. Padidinus doz\u0119 preparatui, kuris jau i\u0161tirpo, gaunami pavir\u0161iaus defektai, o putos i\u0161lieka.<\/p>\n
Taigi techninis klausimas n\u0117ra \u201ckuris put\u0173 slopintuvas yra stipriausias\u201d. Svarbu tai, ar la\u0161elis gali pakankamai ilgai i\u0161silaikyti \u0161iek tiek ne vietoje, kad ir toliau rast\u0173 pl\u0117vel\u0119. Tas laiko tarpas yra trumpas. Jei j\u012f praleisi i\u0161 bet kurios pus\u0117s, bakas v\u0117l atrodys u\u017eimtas, arba pl\u0117vel\u0117 atrodys sutr\u016bkin\u0117jusi.<\/p>","protected":false},"excerpt":{"rendered":"
