Iyini i-Silicone Antifoam

Ama-antifoam e-silicone ngokuvamile akhiwa i-silica e-hydrophobized ehlakazeka kahle ngaphakathi koketshezi lwe-silicone.I-compound ephumayo bese iqiniswa ibe i-emulsion esekelwe emanzini noma e-oyela.Lawa ma-antifoam asebenza kahle kakhulu ngenxa yokungangeni kwawo kwamakhemikhali okuvamile, amandla ngisho nasezindaweni eziphansi, kanye nekhono lokusabalala phezu kwefilimu yegwebu.Uma kudingeka, zingahlanganiswa nezinye izinto eziqinile ze-hydrophobic kanye noketshezi ukuze kuthuthukiswe izakhiwo zazo zokuqeda amagwebu.

Ama-ejenti e-silicone antifoam avame ukuthandwa.Basebenza ngokudiliza ukungezwani okungaphezulu kanye nokuthunaza amagwebu egwebu, okuholela ekuweni kwawo.Lesi senzo sisiza ekuqedeni ngokushesha igwebu elikhona futhi kusiza nokuvimbela ukwakheka kwegwebu.

Izinzuzo ze-silicone defoamer

• Uhlu olubanzi lwezinhlelo zokusebenza

Ngenxa yesakhiwo samakhemikhali esikhethekile samafutha abicah, awahambisani namanzi noma izinto eziqukethe amaqembu amhlophe, noma ama-hydrocarbon noma izinto eziphilayo eziqukethe amaqembu e-hydrocarbon.Njengoba uwoyela we-silicone ungancibiliki ezintweni eziningi, i-silicone defoamer inezinhlobonhlobo zezicelo.Angeke isetshenziselwe izinhlelo zamanzi ahlanza amagwebu kuphela, kodwa futhi nasezinhlelweni zikawoyela okhipha amagwebu.

• Ukungezwani okuphansi kwendawo

Ukungezwani kwendawo kawoyela we-silicone kuvamise ukuba yi-20-21 dynes/cm futhi kuncane kunokuqina kwamanzi (72 dynes/cm) kanye noketshezi olunegwebu oluvamile, okuthuthukisa umphumela wokulawula igwebu.

• Ukuzinza okuhle kokushisa

Ukuthatha amafutha e-silicone e-dimethyl evame ukusetshenziswa njengesibonelo, ukumelana kwayo kokushisa kwesikhathi eside kungafinyelela ku-150 ° C, futhi ukumelana kwayo kwezinga lokushisa kwesikhashana kungafinyelela ngaphezu kuka-300 ° C, ukuqinisekisa ukuthi i-silicone defoaming agents ingasetshenziswa ebangeni lokushisa elibanzi.

• Ukuzinza okuhle kwamakhemikhali

Amafutha e-Silicone anokuqina kwamakhemikhali aphezulu futhi kunzima ukusabela ngamakhemikhali nezinye izinto.Ngakho-ke, uma nje ukulungiswa kunengqondo, ama-silicone defoaming agents avunyelwe ukusetshenziswa ezinhlelweni eziqukethe ama-asidi, ama-alkali, nosawoti.

• Inertia ye-Physiological

Amafutha e-silicone afakazelwe ukuthi awanabo ubuthi kubantu nasezilwaneni.Ngakho-ke, ama-silicone defoamers (anama-emulsifiers angenabuthi afanelekile, njll.) angasetshenziswa ngokuphepha ku-pulp nephepha, ukucubungula ukudla, izicelo zezimboni zezokwelapha, ezemithi nezimonyo.

• Ukukhipha amagwebu okunamandla

Ama-Silicone defoamers awakwazi nje ukuphula ngokuphumelelayo igwebu elingafuneki elikhona, kodwa futhi avimbele ngokuphawulekayo igwebu futhi avimbele ukwakheka kwegwebu.Isilinganiso sincane kakhulu, futhi ingxenye eyodwa kuphela eyisigidi (1 ppm noma 1 g/m3) yesisindo sendawo ekhipha amagwebu ingangezwa ukuze kukhiqizwe umphumela.Ibanga layo elivamile liyi-1 kuya ku-100 ppm.Akukhona nje kuphela ukuthi izindleko ziphansi, kodwa ngeke zingcolise izinto ezikhishwa amagwebu.

Ama-antifoam e-silicone aziswa ngokuzinza kwawo, ukuhambisana nezinto ezihlukahlukene, nokusebenza kahle ekugxilweni okuphansi.Nokho, kubalulekile ukuqinisekisa ukuthi athobelana nezindinganiso zokulawula futhi afanele isicelo esithile ukuze agweme noma yimiphi imiphumela emibi kukhwalithi yomkhiqizo noma indawo ezungezile.
