Silika gel osakaniza makhalidwe, processing luso ndi ntchito

Zida za silika za gel zimakhala ndi mawonekedwe apamwamba adsorption, kukhazikika kwamafuta, kukhazikika kwamankhwala, mphamvu zamakina apamwamba ndi zina zotero, ndipo zimagwiritsidwa ntchito kwambiri popanga zinthu. Ndipo zinthuzo zidasinthidwa kukhala gelisi yapadera ya silika kuti igwirizane ndi zofunikira zazinthu zosiyanasiyana, monga zowala, ma ion oyipa, ma discoloration ndi mawonekedwe ena.

Chiyambi cha gel osakaniza silika

Silika gel osakaniza ndi mtundu wa zinthu kwambiri yogwira adsorption, ndi amorphous mankhwala, amene ali polysiloxane, silikoni mafuta, silika wakuda (silika), coupling agent ndi filler, etc., chigawo chachikulu ndi silika. Insoluble m'madzi ndi zosungunulira zilizonse, zopanda poizoni komanso zopanda pake, zokhazikika zamakina, kuphatikiza pa alkali wamphamvu, hydrofluoric acid samachita ndi chinthu chilichonse. Mitundu yosiyanasiyana ya gelisi ya silika imapanga ma micropore osiyanasiyana chifukwa cha njira zawo zopangira. Mapangidwe a mankhwala ndi mawonekedwe a silika gel amatsimikizira kuti ali ndi makhalidwe azinthu zina zambiri zofanana zomwe zimakhala zovuta kuzisintha: machitidwe apamwamba a adsorption, kukhazikika kwabwino kwa kutentha, kukhazikika kwa mankhwala, ndi mphamvu zamakina apamwamba.

Gulu la silika gel

Silicone ikhoza kugawidwa m'magulu osiyanasiyana:

Malinga ndi zikuchokera akhoza kugawidwa mu: chigawo chimodzi ndi awiri chigawo silika gel osakaniza.
Malinga ndi kutentha vulcanization akhoza kugawidwa mu: mkulu kutentha vulcanization ndi chipinda kutentha vulcanization silikoni.
Malinga ndi mawonekedwe a mankhwala akhoza kugawidwa mu: madzi ndi olimba silika gel osakaniza.
Malinga ndi vulcanization anachita akhoza kugawidwa mu: condensation anachita mtundu, platinamu Kuwonjezera anachita mtundu ndi peroxide kuphatikiza mtundu.
Malinga ndi dongosolo lalikulu la maunyolo amatha kugawidwa kukhala: gel osakaniza silika ndi gel osinthidwa silika.
Malinga ndi makhalidwe mankhwala akhoza kugawidwa mu: mkulu ndi otsika kutentha kukana mtundu, odana malo amodzi mtundu, mafuta ndi zosungunulira kukana, conductive mtundu, thovu siponji mtundu, mkulu mphamvu misozi kukana mtundu, lawi retardant moto chitetezo mtundu, otsika psinjika mtundu mapindikidwe .
