Yini i-antifone antifoam

I-Silicone Antifoams imvamisa yakhiwa nge-silica enziwe nge-hydrophobezed ehlakazeka kahle ngaphakathi koketshezi lwe-silicone. Ingxenye eholele lapho isizinza ibe yi-emulsion esekwe emanzini noma ekwenziweni kawoyela. Lawa ma-antifoams asebenza kahle kakhulu ngenxa yokuhlanzeka kwawo okujwayelekile kwamakhemikhali, i-potency ngisho nokugxila okuphansi, kanye nekhono lokusabalalisa ngefilimu le-foam. Uma kudingekile, zingahlanganiswa namanye ama-solids we-hydrophobic kanye noketshezi ukuze kuthuthukiswe izakhiwo zazo zokucisha.

Ama-agents antifoe antifoam ajwayele ukuthandwa. Basebenza ngokubhidliza ukungezwani komhlaba kanye nokuhlehlisa ama-Foam Bubbles, okuholela ekuweni kwabo. Lesi sifundisa sesenzo ekuqedeni okusheshayo kwe-foam ekhona futhi sisiza ukuvikela ukwakheka kwe-foam.

Izinzuzo ze-silicone defoamer

• Ububanzi bezicelo

Ngenxa yokwakheka okukhethekile kwamakhemikhali amafutha e-silicone, akuhambisani namanzi noma izinto eziqukethe amaqembu ama-polar, nama-hydrocarbons noma ama-hydrocarbons noma ama-organic aqukethe amaqembu e-hydrocarbon. Njengoba u-abicone oyela uyangena ezintweni eziningi, i-silicone defomer inezinhlobonhlobo zezicelo. Ingasetshenziswa hhayi izinhlelo zamanzi ezihlukumezanayo kuphela, kepha futhi nokuncibilikisa amasistimu kawoyela.

• Ukungezwani okuphansi okuphansi

Ukungezwani kwe-silicone oyela ngokuvamile yi-20-21 dynes / cm futhi incane kunokungezwani kwamanzi (72 dys / cm) kanye noketshezi lwamagwebu ajwayelekile, athuthukisa umphumela wokulawulwa kwegwebu.

• Ukuqina okuhle okushisayo

Ukuthatha okuvame ukusetshenziswa ka-dimethyl abicone uwoyela njengesibonelo, ukumelana kwayo kwesikhathi eside kungafinyelela ku-150 ° C, futhi ukumelana kwalo kwesikhashana kungafinyelela ngaphezulu kwama-300 ° C, ukuqinisekisa ukuthi ama-silicone defoauming agents angasetshenziswa ebangeni lokushisa elibanzi.

• Ukuqina okuhle kwamakhemikhali

Amafutha e-Silicone anokuqina okuphezulu kwamakhemikhali futhi kunzima ukuphendula ngamakhemikhali nezinye izinto. Ngakho-ke, inqobo nje uma ukulungiswa kunengqondo, ama-silicone defouming agents avunyelwe ukuthi asetshenziswe ezinhlelweni ezinama-acid, alkali, nosawoti.

• I-Inertia ye-Inertia ye-Physioliological

Uwoyela we-silicone ufakazelwe ukuthi awunanyanya kubantu nasezilwaneni. Ngakho-ke, ama-silicone defoamers (ane-emulseliers efanelekile engeyona eye-anexic, njll.) Angasetshenziswa ngokuphephile ku-pulp nasephepheni, ukucubungula kokudla, izinhlelo zokusebenza zezimboni zezokwelapha kanye nezimonyo.

• I-desouming enamandla

Ama-silicone defoamers awakwazi ukwephula amandla akhona kuphela, kepha futhi avimbela kakhulu amagwebu futhi avikele ukwakheka kwamagwebu. Umthamo umncane kakhulu, futhi ingxenye eyodwa kuphela yesigidi (1 ppm noma i-1 g / m3) yesisindo se-Foaming Medium ingangezwa ukukhiqiza umphumela wokungcolisa. Uhla lwayo oluvamile luyi-1 kuye ku-100 ppm. Hhayi nje kuphela ukuthi izindleko ziphansi, kepha ngeke zingcolise izinto zokwakha zingcoliswe.

I-Silicone Antifoams ibaluleke ngokuqina kwazo, ukuhambisana nezinto ezahlukahlukene, kanye nokusebenza kahle ekugxileni okuphansi. Kodwa-ke, kubalulekile ukuthi uqinisekise ukuthi bahambisana namazinga alawulayo futhi balungele uhlelo oluthile lokugwema noma yimiphi imiphumela emibi kwikhwalithi yomkhiqizo noma kwimvelo.
