Yintoni iSilicone Antifoam

I-silicone antifoams ngokuqhelekileyo yenziwe nge-silica e-hydrophobized ehlakazwe kakuhle ngaphakathi kwe-silicone fluid.I-compound ephumayo emva koko iqiniswe kwi-emulsion yamanzi okanye i-oyile.Ezi antifoams zisebenza kakhulu ngenxa ye-inertness yazo yekhemikhali ngokubanzi, amandla nakwizinto eziphantsi, kunye nokukwazi ukusasazeka kwifilimu yegwebu.Ukuba ziyimfuneko, zinokudityaniswa nezinye izinto eziqinileyo ze-hydrophobic kunye nolwelo ukuphucula iipropathi zazo zokuthoba amagwebu.

I-silicone antifoam agents zihlala zikhethwa.Basebenza ngokonakalisa ukuxinezeleka komphezulu kunye nokutshabalalisa amaqamza amagwebu, okukhokelela ekuweni kwawo.Esi senzo sincedisa ekuphelisweni ngokukhawuleza kwe-foam ekhoyo kwaye kunceda ukuthintela ukubunjwa kwe-foam.

Izinto eziluncedo ze-silicone defoamer

• Uluhlu olubanzi lwezicelo

Ngenxa yokwakheka kweekhemikhali ezikhethekileyo zeoli ye-silicone, ayihambelani namanzi okanye izinto eziqukethe amaqela e-polar, okanye kunye ne-hydrocarbons okanye izinto eziphilayo eziqukethe amaqela e-hydrocarbon.Ekubeni ioli ye-silicone ayinyibiliki kwizinto ezininzi, i-silicone defoamer inoluhlu olubanzi lwezicelo.Ayinakusetyenziswa kuphela kwiinkqubo zamanzi ezikhupha ugwebu, kodwa kunye neenkqubo ze-oyile ezikhupha amagwebu.

• Ukuxinezeleka okuphantsi komhlaba

Uxinzelelo lomphezulu weoyile ye-silicone ngokuqhelekileyo yi-20-21 dynes / cm kwaye incinci kunoxinzelelo lwamanzi (72 dynes / cm) kunye nolwelo olugwebu ngokubanzi, oluphucula umphumo wokulawula ugwebu.

• Ukuzinza kakuhle kwe-thermal

Ukuthatha i-oyile ye-silicone ye-dimethyl esetyenziswa ngokuqhelekileyo njengomzekelo, ukuxhathisa ukushisa kwexesha elide kunokufikelela kwi-150 ° C, kwaye ukuxhathisa ukushisa kwexesha elifutshane kunokufikelela ngaphezu kwe-300 ° C, ukuqinisekisa ukuba i-silicone defoaming agents ingasetyenziselwa kwiqondo lokushisa elibanzi.

• Uzinzo oluhle lweekhemikhali

Ioli ye-Silicone inozinzo oluphezulu lweekhemikhali kwaye kunzima ukusabela ngamachiza kunye nezinye izinto.Ngoko ke, nje ukuba ukulungiswa kunengqiqo, i-silicone defoaming agents ivumelekile ukuba isetyenziswe kwiinkqubo eziqukethe i-acids, i-alkali kunye neetyuwa.

• Inertia yePhysiological

Ioli ye-silicone ibonakaliswe ukuba ayinayo ityhefu ebantwini nakwizilwanyana.Ngoko ke, i-silicone defoamers (kunye ne-emulsifiers efanelekileyo engeyiyo inetyhefu, njl.) ingasetyenziselwa ngokukhuselekileyo kwi-pulp kunye nephepha, ukucutshungulwa kokutya, ukusetyenziswa kwezonyango, amayeza kunye ne-cosmetic.

• Ukukhupha amagwebu ngamandla

I-Silicone defoamers ayikwazi ukuphula ngokufanelekileyo i-foam ekhoyo engafunekiyo, kodwa inqande kakhulu i-foam kwaye inqande ukubunjwa kwe-foam.Idosi incinci kakhulu, kwaye sisigidi esinye kuphela (1 ppm okanye 1 g/m3) sobunzima besixhobo esiphuphuma ugwebu sinokongezwa ukuvelisa isiphumo sokubola.Uluhlu lwayo oluqhelekileyo luyi-1 ukuya kwi-100 ppm.Akunjalo kuphela ixabiso eliphantsi, kodwa aliyi kungcolisa izinto ezichithwayo.

Ii-antifoam ze-silicone zixabiswa ngokuzinza kwazo, ukuhambelana nezinto ezahlukeneyo, kunye nokusebenza kwiindawo eziphantsi.Nangona kunjalo, kubalulekile ukuqinisekisa ukuba ziyayithobela imigangatho yolawulo kwaye zifanelekile kwisicelo esithile ukuphepha nayiphi na imiphumo emibi kumgangatho wemveliso okanye okusingqongileyo.
