Hydrated Silicone Dioxide rau Silicone Rubber
Precipitated silica yog ib hom dawb carbon dub uas feem ntau siv los tsim cov roj hmab silicone. Cov khoom no yog tus cwj pwm los ntawm nws cov khoom sib cais zoo, uas muab rau nws thaj chaw siab thiab cov khoom tshwj xeeb xws li fluidity siab, zoo heev dispersibility, thiab tsis tshua muaj roj nqus.
Ib qho ntawm cov kev siv tseem ceeb tshaj plaws ntawm precipitated silica nyob rau hauv silicone roj hmab yog raws li ib tug reinforcing muab tub lim. Cov khoom siv no tuaj yeem txhim kho cov khoom siv hluav taws xob zoo ntawm silicone roj hmab, nrog rau lub zog tensile, tsim kua muag tsis kam, thiab kev puas tsuaj. Nws tuaj yeem txhim kho cov khoom ua haujlwm ntawm silicone roj hmab, xws li viscosity, ntws, thiab kho tus nqi.
Ntxiv nrog rau nws siv los ua ib qho kev txhawb nqa, cov silica precipitated kuj tau siv dav los ua tus neeg saib xyuas kev thaiv hauv ntau daim ntawv thov. Cov khoom no tuaj yeem muab ntxiv rau cov txheej txheem, cov yas, thiab cov yeeb yaj kiab los tiv thaiv lawv los ntawm kev sib tsoo los yog lwm qhov chaw. Cov cuab yeej no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas cov yeeb yaj kiab lossis cov txheej txheem yuav tsum tau muab tso rau hauv cov yob.
Lwm daim ntawv thov ntawm precipitated silica nyob rau hauv silicone roj hmab muaj xws li ib tug flatting tus neeg sawv cev, uas yuav txo tau cov gloss ntawm coatings, thiab raws li ib tug rheology modifier, uas yuav txhim kho lub thixotropic zog ntawm cov kua. Cov khoom siv no tseem tuaj yeem siv rau hauv cov khoom noj thiab tshuaj siv los ua tus neeg sawv cev tiv thaiv kab mob lossis ua cov cab rau cov khoom xyaw nquag.
Zuag qhia tag nrho, cov khoom tshwj xeeb ntawm precipitated silica ua rau nws yog ib qho tseem ceeb hauv kev tsim cov roj hmab silicone thiab suav tsis tau lwm yam kev siv. Nws cov kev ua haujlwm siab thiab ntau yam ua rau nws yog qhov kev xaiv nrov rau cov tuam ntxhab thoob plaws ntau qhov kev lag luam.
