Kutsegula p – tert – amylphenol: Katswiri Wosiyanasiyana M'munda Wamafakitale

Mu malo akuluakulu amakampani amakono, p – tert – amylphenol imawala ngati ngale yowala, ikuwala mwapadera.

Ponena za kapangidwe kake ka mankhwala, ili ndi mawonekedwe apadera a mamolekyulu, zomwe zimaipatsa mphamvu yochita bwino kwambiri komanso kukhazikika. M'mawonekedwe ake, imawoneka ngati yoyera mpaka yachikasu yopepuka, kaya ngati ma briquette, ma flakes, kapena ufa wosalala. Pansi pa mitundu yapaderayi pali kuthekera kwakukulu.

Popanga ma phenolic resins, ndi chinthu chofunikira kwambiri popanga. Utomoni wa p – tert – amylphenol formaldehyde wopangidwa ndi polycondensation yokhala ndi formaldehyde umasonyeza kukana kutentha, kukana madzi, komanso mphamvu zamakanika. Mu gawo la zokutira, izi zimathandiza kuti ziwonjezere kuuma, kunyezimira, ndi kumamatira kwa zokutira, zomwe zimapangitsa kuti zokutirazo zisakhale zokongola zokha komanso zotetezeka kwa nthawi yayitali pa chinthu chophimbidwa. Mu gawo la zomatira, zimatha kulimbitsa mphamvu yolumikizana ndi kukana kutentha, kulumikiza mwamphamvu zipangizo zosiyanasiyana komanso kupirira mayeso otentha kwambiri.

Mu makampani opanga rabala, imanyamula maudindo awiri a antioxidant ndi plasticizer. Monga antioxidant, imaletsa bwino kukhuthala ndi kukalamba kwa rabala, ndikuwonjezera nthawi yogwira ntchito ya zinthu za rabala. Monga plasticizer, imawongolera mphamvu zogwirira ntchito, imawonjezera kusinthasintha ndi kusinthasintha, ndikupangitsa kuti kukonza rabala kukhale kosavuta.

Pambuyo powonjezera ethylene oxide ndi propylene oxide, imasandulika kukhala surfactant yokhala ndi ntchito yabwino kwambiri. Mu sopo, imachepetsa mphamvu ya pamwamba pa madzi ndipo imachotsa mafuta m'thupi mwamphamvu ndikufalitsa madontho a mafuta. Mu zodzoladzola, imagwira ntchito ngati emulsifier kuti isunge bata ndi kapangidwe ka zinthu. Mu makampani opanga mankhwala ophera tizilombo, imathandiza zosakaniza zogwira ntchito kufalikira ndikuyimitsidwa mofanana, zomwe zimapangitsa kuti ntchitoyo igwire bwino ntchito.

Ndi makhalidwe ake abwino kwambiri, p – tert – amylphenol yalowa m'mafakitale ambiri, zomwe zapangitsa kuti pakhale chitukuko cha mafakitale. Kusankha p – tert – amylphenol kumatanthauza kusankha njira yabwino kwambiri komanso yapamwamba kwambiri yopangira mafakitale, zomwe zikutsegula mutu watsopano pakupanga mafakitale.
