Kukula kwamachitidwe a organic defoamers mumakampani opanga mapepala. Kafukufuku wogwiritsa ntchito othandizira padziko lapansi akusintha kuchoka pamtundu umodzi wambiri kukhala mtundu wophatikiza. Maiko padziko lonse lapansi apereka ndalama zochuluka zothandizira anthu kuti azigwiritsa ntchito mankhwala osokoneza bongo. Ndi ndalama ndi chuma, zotsatira zambiri za upainiya zakwaniritsidwa, ndipo magwiridwe antchito amtundu wa organic defoamers asinthidwa bwino kwambiri. Luso la kukonzekera kwachilengedwe ndi momwe imagwiritsidwira ntchito likuwonetsa chitukuko chachikulu. Monga gawo lofunikira labanja lachilengedwe, ma organic defoamers ali ndi chitukuko chofananira m'makampani opanga mapepala.

Monga tonse tikudziwa, m'makampani opanga mapepala apamwamba omwe amaimiridwa ndi oleic acid amide, polyether, ndi zinthu zachilengedwe, ma organic defoamers asinthana kwathunthu ndi mitundu yosakwanira yamafuta amafuta, mafuta azamasamba, mowa, ndi zina zambiri, ndipo athandiza kwambiri ku makampani opanga mapepala. Nthawi zambiri, ma polyether silicone defoamers amasinthidwa kuchokera poyambira osiyanasiyana. Silicone defoamers itha kugwiritsidwa ntchito ngati maziko osankhira polyether silicone defoamers. Malinga ndi kusiyana kwawo, ma polyether silicone defoamers amatha kugawidwa kukhala mtundu wa polyol ndi mafuta acid ester, ndiye mtundu wa amine ether. Mitundu iyi yama defoamers ili ndi mawonekedwe awo.

Makina owunikira amasiyana ndi ena operewera mwachilengedwe. Magulu osadziwika ndi ofanana ndi osagwira ntchito, ndipo alibe mgwirizano ndi mankhwala omwe ali ndi madzi, magulu a hydrocarbon kapena magulu opatsa chidwi. Poyerekeza ndi ma organic silicon defoamers, imatha kutsitsa. Khama, nthawi zambiri limangofunika kuwonjezera kuchuluka kwa 1×10-6 ~ 75×10-6 yoyendetsedwa ndi dongosololi kuti ipeze zomwe zikuyembekezeredwa zakuchotsa pamtundu wapamwamba.

Zinthu zakuthupi zimatha kusakanikirana ndi zinthu zambiri, ndipo sikophweka kuyanjana ndi mankhwala a thovu. Organic defoamers ali ndi kutentha kwabwino kukana komanso kukana kuyesedwa kwapamwamba komanso kutsika. Kutalika kwa mafuta a methyl silicone kumakwera pang'onopang'ono pafupifupi 200°C, ndipo chomangira cha silicon-oxygen sichitha. Mafuta a methyl silicone ali ndi kusinthasintha kwabwino komanso konyowa. Chifukwa chake, silicone defoamer ndiyopindulitsa kukonza pepala lokutidwa.

Organic defoamers ndiotetezeka, kupanga zobiriwira, komanso kutalikitsa thupi. Izi yapamwamba ndi wanzeru kupanga pawiri. Organic defoamers ali ndi anti-ukalamba, magwiridwe antchito ndi zinthu zotsutsana ndi ukalamba. Itha kugwiritsidwa ntchito kwathunthu pamiyeso yonse yazachilengedwe. Organic defoamers ali okwera Magwiridwe antchito amtundu wonse, koma mtengo wake ndiwokwera. Itha kugwiritsidwa ntchito pazochitika zilizonse pamakampani opanga mapepala, ndikuchita bwino kwambiri ndipo nthawi zina sizimagwira.

Chifukwa chake, organic defoamer imatha kuphatikizidwa ndi ma surfactant ena monga oleic acid amide ndi polyether ndi demulsification ndi kuponderezedwa kwa thovu kuti apange gulu la organic defoamer, lomwe silingangopititsa patsogolo kuthekera kwaukadaulo kwa thovu la organic defoamer, komanso Kuchepetsa mtengo wachindunji wa katundu. Ndikukula kwa akatswiri opanga ma surfactant, ma organic defoamers ali ndi mwayi wogulitsa msika komanso msika waukulu.
