Hydrophilic Fumed Silika
Chiyambi cha Zamalonda
Silika yofukizira, kapena silika ya pyrogenic, colloidal silicon dioxide, ndi amorphous white inorganic powder yomwe ili ndi malo apamwamba kwambiri, kukula kwa tinthu tating'onoting'ono tomwe timakhala tinthu tating'onoting'ono (pakati pa zinthu za silika) ndende yamagulu a silanol pamwamba. The katundu wa fumed silica akhoza kusinthidwa mankhwala ndi zochita ndi magulu silanol.
Silika yofukiza yamalonda yomwe ilipo imatha kugawidwa m'magulu awiri: hydrophilic fumed silica ndi hydrophobic fumed silica. amagwiritsidwa ntchito kwambiri ngati chinthu chofunikira m'mafakitale ambiri monga mphira wa silicone, mafakitale a utoto ndi mapulasitiki.
Makhalidwe Aakulu
1, kubalalitsidwa kwabwino, anti-kumira komanso kutsatsa.
2, Mu rabara ya silikoni: kulimbitsa kwambiri, kukana misozi, kukana bwino kwa abrasion, kuwonekera bwino.
3, mu utoto: anti-sagging, anti-kukhazikitsa, kusintha pigment bata, kusintha pigment kubalalitsidwa, kusintha filimu adhesion, odana ndi dzimbiri, madzi, kupewa kutumphukira, kuthandizira otaya, kumapangitsanso kulamulira rheological.
4, Yogwiritsidwa ntchito pamtundu uliwonse wa utoto (zomatira, zokutira, inki) kuti zithandizire kukhazikika kwa pigment, kupititsa patsogolo kubalalitsidwa kwa pigment, kupititsa patsogolo filimu, anti-corrosion, madzi, anti-kukhazikitsa, anti-bubbling, makamaka kwa silikoni mphira kulimbitsa, zomatira thixotropic wothandizira, anti-kukhazikitsa wothandizila kwa mitundu.
5, chifukwa chamadzimadzi amatha kukhuthala, kuwongolera kwa rheology, kuyimitsidwa, kutsutsa-sagging ndi maudindo ena.
6, Pakuti olimba dongosolo akhoza kupititsa patsogolo kuwongola, kuvala zosagwira ndi zina zotero.
7, Pakuti dongosolo ufa akhoza kusintha otaya ufulu ndi kupewa agglomeration ndi zotsatira zina. Itha kugwiritsidwanso ntchito ngati zodzaza kwambiri zodzaza mphira wachilengedwe komanso wopangira, mankhwala ndi zodzoladzola.

Product Application
Amagwiritsidwa ntchito makamaka mu mphira silikoni (HTV, RTV), utoto, zokutira, inki, zamagetsi, papermaking, mafuta, CHIKWANGWANI chamawonedwe chingwe mafuta, utomoni, utomoni, galasi CHIKWANGWANI analimbitsa pulasitiki, galasi zomatira (sealant), zomatira, defoamers, solubilizers, mapulasitiki, ziwiya zadothi ndi mafakitale ena.
Kupaka ndi Kusunga
1. Wophatikizidwa mu mapepala angapo osanjikiza a kraft
Matumba 2.10kg pa mphasa
3. Zisungidwe muzolemba zoyambirira mu zouma
4. Kutetezedwa ku zinthu zosasinthika
