Zokhudza Ochotsa Mafoam (Antifoam)

Pali mitundu yambiri yaZonyozandipo amagwiritsidwa ntchito kwambiri. Njira yochepetsera thovu ndi "kusweka kwa thovu" ya defoamer ndi iyi: pamene defoamer yowonjezeredwa ku dongosolo, mamolekyu ake amagawidwa mwachisawawa pamwamba pa madzi, zomwe zimalepheretsa kupanga filimu yotanuka, kutanthauza kuti, kuthetsa kupanga thovu. Dongosolo likapanga thovu lalikulu, onjezerani defoamer, mamolekyu ake amafalikira nthawi yomweyo pamwamba pa thovu, amafalikira mofulumira, amapanga wosanjikiza woonda kwambiri wa filimu iwiri, amafalikira kwambiri, amalowa, ndikulowa m'magawo, motero amalowa m'malo mwa khoma lopyapyala la filimu yoyambirira ya thovu. Chifukwa cha kupsinjika kwake kochepa pamwamba, imapita ku madzi ndi kupsinjika kwakukulu pamwamba komwe kumapanga thovu, kotero kuti mamolekyu a defoamer okhala ndi kupsinjika kochepa pamwamba amapitilira kufalikira ndikulowa pakati pa mawonekedwe a gasi ndi madzi, zomwe zimapangitsa kuti khoma la filimu likhale lochepa mofulumira, ndipo thovu limakhudzidwanso ndi pamwamba pozungulira. Saizi ya filimu yokhala ndi kupsinjika kwakukulu imakoka mwamphamvu, kotero kuti kupsinjika kozungulira thovu sikuli koyenera, zomwe zimapangitsa kuti "thovu lisweke". Mamolekyu a defoamer omwe sasungunuka mu dongosololi adzalowanso pamwamba pa filimu ina ya thovu, ndipo zina zotero, thovu lonse lidzawonongedwa kwathunthu.

Momwe mungasankhire cholondolaCholetsa thovu

Kupanga ndi kupanga zophimba kudzapanga thovu mosiyanasiyana. Kupanga thovu kumalepheretsa kupita patsogolo bwino kwa kupanga ndi kumanga, ndipo nthawi yomweyo kumabweretsa zolakwika pa filimu yophimba yomalizidwa. Kusankha koyenera kwa defoamer yoyenera kungathandize kuti kupanga ndi kumanga zophimba kupite patsogolo mwachizolowezi.

Ntchito ya defoamer: kuwononga filimu yamadzimadzi pamwamba pa thovu, kuletsa kupangika kwa thovu ndikulimbikitsa kugwa kwa thovu. Defoamer imagwiritsidwa ntchito pa thovu lalikulu, ndipo thovu laling'ono liyenera kugwiritsidwa ntchito limodzi ndi kuchotsa mpweya ndi kuchotsa poizoni.

Mawonekedwe a defoamer: Defoamer sisungunuka mu sing'anga, koma imatha kulowa ndikufalikira mu sing'anga ngati madontho ang'onoang'ono. Dayamita yogwira ntchito kwambiri ya madontho ang'onoang'ono a defoamer ndi yofanana ndi makulidwe a khoma la thovu.

Kapangidwe ka defoamer:ZonyozaZophimba zopangidwa ndi madzi zimagawidwa m'mitundu yopanda silicon ndi yokhala ndi silicon.ZonyozaZili ndi zigawo zotsatirazi:

Chogwira ntchito: Chimagwira ntchito ngati chophwanya thovu ndi chochotsera thovu chomwe chili ndi mphamvu yochepa pamwamba. Zina mwa izo ndi mafuta a nyama ndi ndiwo zamasamba, silica yofooka ndi madzi, alcohols apamwamba, ndi zina zotero.

Chothandizira kufalikira: Chonyowetsa emulsifier kuti zitsimikizire kuti madontho ang'onoang'ono otulutsa madzi akufalikira ndikukhudza filimu ya thovu ndikufalikira. Pali non(octyl) phenol polyoxyethylene ether, sopo salt ndi zina zotero.

Chonyamulira: Chimathandiza kuti chinthu chogwira ntchito chigwirizane ndi makina opangira thovu, ndipo n'chosavuta kufalitsa mu makina opangira thovu. Kuphatikiza zonsezi, chimakhala ndi mphamvu yochepa pamwamba, chimathandiza kuletsa thovu, ndipo chimatha kuchepetsa ndalama.

Zinthu ziwiri ziyenera kukwaniritsidwa pochotsa thovu: chinthu cholowera: E=γ1+γ12-γ3 > 0, kuti zitsimikizire kuti chochotsera thovu chikulowa mu khoma la thovu; chinthu chofalikira S=γ1-v12-γ3 >0, kuti zitsimikizire kuti madontho a chochotsera thovu akufalikira.
