Lwil silikon ki wo -idwojèn se yon konpoze organosilicon ki gen lyezon idwojèn Silisyòm-(Si-H). Akòz gwo reyaksyon li, estabilite chimik, ak kapasite pou fòme fim-, li jwe yon wòl enpòtan nan plizyè domèn endistriyèl. Sa ki anba la yo se domèn aplikasyon debaz li yo ak itilizasyon espesifik, rezime ki baze sou prèv:
Waterproofing (aplikasyon debaz)
Prensip: Idwojèn -ki gen lwil silikone a sèvi ak de molekil ki pa polè, silisyòm-bond oksijèn (Si-O) ak gwoup methyl (-CH₃), pou repouse imidite. Anba aksyon an nan yon katalis, molekil yo crosslink nan tanperati ki ba yo fòme yon fim dans, ki se Lè sa a, byen fèm tache ak sifas la substra atravè lyezon chimik, reyalize efikas ak long -ki dire lontan ki enpèmeyab, imidite-prèv, ak efè ranfòsman multifonksyonèl.
1. Materyèl bilding ak substrats: Itilize sou sifas tankou vè, seramik, metal, siman, mab, ak wòch yo fòme yon manbràn dans ki enpèmeyab, amelyore enpèmeyab ak lavi sèvis. Espesyalman fèt pou materyèl dekoratif tankou tablo jips ak blòk jips, siyifikativman diminye absòpsyon dlo (egzanp,<10%, meeting national standards).
2. Fabric Finishing: Treats fibers such as cotton, linen, silk, acrylic, and polyester, imparting water and stain resistance, improving hand feel, drape, and tear strength; when used with hydroxyl silicone oil emulsions, it maintains breathability. Finishing Principle: Chemical Action: On one hand, the Si-H bonds in high-hydrogen silicone oil molecules have high reactivity. Under the action of metal salt catalysts (such as tin and zinc salts), they can undergo condensation reactions with hydroxyl groups (-OH) on the surface of cellulose fibers (cotton, linen, etc.) or amino groups (-NH₂) on protein fibers (silk, wool), forming stable Si-O-C or Si-N-C covalent bonds. This bonding firmly anchors the siloxane backbone to the fiber surface, improving functional durability. On the other hand, the remaining Si-H bonds hydrolyze under the action of moisture and carbon dioxide in the air to generate silanols (Si-OH), which further condense and crosslink to form a three-dimensional network elastic film covering the fiber surface. In terms of physical effects: On the one hand, the methyl groups (-CH₃) in the siloxane segments are oriented on the fiber surface, forming a low surface energy (20-24 mN/m) hydrophobic layer, significantly reducing the surface tension of the fabric and ensuring a water droplet contact angle >90 degre, kidonk reyalize WATERPROOFING ak rezistans tach. Nan lòt men an, kolòn vètebral polysiloxane trè fleksib fizikman adsorbe ak ankapsule fib yo, diminye friksyon fib entè - ak siyifikativman amelyore tendres, lis, ak drape twal la. Efè a se menm plis pwononse lè yo itilize ansanm ak methyl hydroxy silicone lwil, tankou emulsion.
3. Materyèl poud yo itilize pou trete ajan sèk poud dife, mika, ajil, elatriye, pou anpeche clumping ak amelyore likidite.
Modifye entèmedyè silikon lwil oliv
Kòm yon matyè premyè kle, lwil oliv silicone polyether-modifye, lwil oliv silicone alkyl-modifye, ak lwil oliv silicone epoksidik-modifye yo sentèz atravè reyaksyon idrosililasyon, epi yo itilize nan estabilize kim, ajan fini twal, elatriye.
Kosmetik ak famasetik
Kosmetik: Yo itilize kòm yon ajan idrofob, librifyan, ak idratan nan fondasyon ki baze sou lwil oliv -pou amelyore eksperyans itilizatè yo ak pwoteksyon po. Famasetik: Yo itilize kòm yon pòtè dwòg oswa ajan lage -pou amelyore byodisponibilite.
Lubrification ak demoulding
Lubrifyan: Yo itilize nan kawotchou ak plastik BEARINGS ak angrenaj pou diminye mete. Ajan lage: Ankouraje ekspilsyon pwodwi pandan pwosesis mwazi, amelyore efikasite, elatriye; tou yo itilize nan manifakti pwodwi kawotchou, papye ak pwosesis fib vè, ak fabrikasyon lank, pami lòt jaden.
