Kodi zotsatira za chithandizo chothandizira ndi chiyani ndipo ndi zotani zomwe zimathandizira?

Thandizo la Catalyst ndi gawo lapadera la chothandizira cholimba. Ndiwo dispersant, binder ndi chithandizo cha zigawo zogwira ntchito za chothandizira, ndipo nthawi zina zimagwira ntchito ya Co catalyst kapena cocatalyst. Thandizo la Catalyst, lomwe limadziwikanso kuti Thandizo, ndi chimodzi mwazinthu zothandizira zothandizira. Nthawi zambiri ndi porous zinthu zomwe zili ndi malo enieni. Zigawo zogwira ntchito za chothandizira nthawi zambiri zimamangiriridwa kwa izo. Chonyamuliracho chimagwiritsidwa ntchito makamaka kuthandizira zigawo zogwira ntchito ndikupanga chothandizira kukhala ndi zinthu zenizeni zakuthupi. Komabe, chonyamuliracho nthawi zambiri sichikhala ndi ntchito yothandiza.

Zofunikira pa chithandizo chamankhwala
1. Ikhoza kuchepetsa kuchuluka kwa zigawo zogwira ntchito, makamaka zitsulo zamtengo wapatali
2. Ndipo akhoza kukonzedwa mu mawonekedwe enaake
3. Sintering pakati pa zigawo zogwira ntchito akhoza kupewedwa pamlingo wakutiwakuti
4. Angathe kukana chiphe
5. Ikhoza kuyanjana ndi zigawo zogwira ntchito ndikugwira ntchito limodzi ndi chothandizira chachikulu.

Zotsatira za chithandizo chothandizira
1. Kuchepetsa mtengo wothandizira
2. Kupititsa patsogolo mphamvu zamakina za chothandizira
3. Kupititsa patsogolo kukhazikika kwa kutentha kwa chothandizira
4. Ntchito ndi kusankha kwa chothandizira chowonjezera
5. Kutalikitsa moyo wolimbikitsa

Chidziwitso cha zonyamulira zingapo zoyambirira
1. Adamulowetsa aluminiyamu: chonyamulira ambiri ntchito kwa chothandizira mafakitale. Ndizotsika mtengo, zimakhala ndi kutentha kwakukulu, ndipo zimakhala ndi chiyanjano chabwino ndi zigawo zogwira ntchito.
2. Gel silika: mankhwala opangidwa ndi SiO2. Nthawi zambiri imakonzedwa ndi galasi lamadzi la acidifying (Na2SiO3). Silicate imapangidwa pambuyo pa sodium silicate imachita ndi asidi; Silicic acid imapanga ma polima ndikumangika kupanga ma polima osatsimikizika.
SiO2 ndi chonyamulira chogwiritsidwa ntchito kwambiri, koma ntchito yake ya mafakitale ndi yocheperapo kuposa ya Al2O3, yomwe ili chifukwa cha zolakwika zotere monga kukonzekera kovuta, kugwirizana kofooka ndi zigawo zogwira ntchito, ndi kusungunula kosavuta pansi pa kukhalapo kwa nthunzi ya madzi.
3. Sieve ya molekyulu: ndi crystalline silicate kapena aluminosilicate, yomwe ndi pore ndi cavity system yopangidwa ndi silicon oxygen tetrahedron kapena aluminium oxygen tetrahedron yolumikizidwa ndi oxygen mlatho chomangira. Ili ndi kukhazikika kwamafuta ambiri, kukhazikika kwa hydrothermal ndi kukana kwa asidi ndi alkali
