1 Ukunganyibiliki okanye ukunyibilika kakubi kulwelo olugwebuyo kuthetha ukuba ugwebu lwaphukile, kunye nedefoamerkufuneka igxininiswe kwaye igxininiswe kwifilimu ye-foam. Kwi-defoamer, kufuneka igxininiswe kwaye igxininiswe ngokukhawuleza, kunye ne-defoamer, kufuneka ihlale igcinwe kule meko.
Ngoko ke, i-defoamer ikwimeko engaphezulu kwe-supersaturated kulwelo olunogwebu, kwaye kulula ukufikelela kwi-supersaturated state kuphela ukuba ayinyibiliki okanye ayinyibiliki kakuhle. I-insoluble okanye i-soluble kakubi, kulula ukuqokelela kwi-interface ye-gas-liquid, kulula ukugxila kwifilimu ye-foam, kwaye inokudlala indima kwi-concentration ephantsi. I-defoamers esetyenziswe kwiinkqubo zamanzi, iamolekyu zezithako ezisebenzayo kufuneka zibe yi-hydrophobic enamandla kunye ne-hydrophilic ebuthakathaka, kwaye ixabiso le-HLB kufuneka libe kuluhlu lwe-1.5-3 ukuze lusebenze kakuhle.
2 Uxinzelelo lomphezulu lungaphantsi kunolwelo olugwebu ugwebu. Kuphela xa i-intermolecular force ye-defoamer incinci kwaye ukunyanzeliswa komhlaba kuphantsi kunoko lwe-foaming liquid, ingaba iinqununu ze-defoamer zinokucwiliswa kwaye zandiswe kwifilimu ye-foam. Kuyafaneleka ukuba uqaphele ukuba ukunyanzeliswa komphezulu wolwelo olunegwebu alukho ukunyanzeliswa komphezulu wesisombululo, kodwa ukunyanzeliswa komphezulu wesisombululo se-foaming.
3. Iqondo elithile lokunxulumana nolwelo olugwebu. Ekubeni inkqubo yokukhupha amagwebu eneneni ilukhuphiswano phakathi kwesantya sokuwa kwegwebu kunye nesantya sokuvelisa amagwebu, i-defoamer kufuneka ikwazi ukusasaza ngokukhawuleza kulwelo olugwebuyo ukuze ikwazi ukudlala indima ngokukhawuleza kuluhlu olubanzi lolwelo olugwebu. Ukwenza i-defoamer isasazeke ngokukhawuleza, izithako ezisebenzayo ze-defoamer kufuneka zibe neqondo elithile lobudlelwane kunye nolwelo olugwebu. Ukuba izithako ezisebenzayo ze-defoamer zisondele kakhulu kwi-foaming liquid, ziya kuchithwa; ukuba zithe qelele kakhulu, kuya kuba nzima ukuzichithachitha. Kuphela xa ubudlelwane bufanelekile, umphumo uya kuba mhle.
4. Akukho kusabela kweekhemikhali kulwelo olugwebu. I-defoamer isabela kunye nolwelo olugwebu. Ngakolunye uhlangothi, i-defoamer iya kulahlekelwa yimpembelelo yayo, kwaye ngakolunye uhlangothi, izinto ezinobungozi zinokuveliswa, ezichaphazela ukukhula kwee-microorganisms.
5. Ukungazinzi okuphantsi kunye nexesha elide lesenzo. Okokuqala, misela inkqubo apho kufuneka kusetyenziswe i-defoamer, ingaba yinkqubo yamanzi okanye i-oyile. Umzekelo, kwishishini lokubilisa, i-oyile-based defoamers njengei-polyether-modified silicone okanye i-polyether kufuneka isetyenziswe. Ishishini lokugubungela ngamanzi kufuneka lisebenzise i-defoams yamanzi kunye ne-silicone defoamers. Khetha i-defoamer, thelekisa isixa sokongeza, kwaye ubhekisele kwixabiso lokufumana eyona mveliso ifanelekileyo kunye neyoqoqosho ye-defoamer.
Ukuziphendulela: Ezinye izixhobo ezikweli qonga zivela kwi-Intanethi okanye zibonelelwa ngamashishini. Sihlala singathathi hlangothi kwiimbono zenqaku. Eli nqaku lereferensi kunye nonxibelelwano kuphela kwaye alinakusetyenziselwa iinjongo zorhwebo. Ilungelo lokushicilela lelombhali wokuqala. Ukuba kukho naluphi na ulwaphulo-mthetho, nceda uqhagamshelane nathi ukuze ulucime. Enkosi ngengqalelo yakho kunye nenkxaso!
