Chinthu chimodzi chomwe chikukula kwambiri m'makampani opanga mankhwala ndi mafakitale ndi stearic acid ufa.
Stearic acid ufa ndi ufa wa crystalline woyera womwe umakhala wopanda fungo komanso wosakoma. Mankhwala, amakhala ndi kukhazikika kwabwino komanso kukhazikika kwamafuta ndipo sangatengeke ndi machitidwe amankhwala, omwe amalola kuti asunge zinthu zake m'malo osiyanasiyana. Kuphatikiza apo, ufa wa stearic uli ndi mafuta ena odzola komanso hydrophobic, ndipo zinthu izi zimayika maziko ogwiritsira ntchito m'magawo osiyanasiyana.
Stearic acid ufa umachokera kuzinthu zosiyanasiyana. Amachokera ku mafuta achilengedwe a nyama ndi masamba ndi mafuta, monga mafuta a kanjedza ndi tallow. Kupyolera mu njira zingapo zopangira mankhwala ndi kuyeretsa, mafuta acids mu mafuta ndi mafutawa amasiyanitsidwa ndikuyeretsedwa kuti pamapeto pake apeze ufa wa stearic acid. Njira yopezera izi imatsimikizira kukhazikika kwazomwe zimaperekedwa ndikuchepetsa kukhudzidwa kwake ndi chilengedwe pamlingo wina.
Stearic acid ufa umapambana zikafika pakuchita bwino. Choyamba, ndi mafuta abwino kwambiri omwe amatha kuchepetsa mikangano ndi kuvala, ndikuwongolera magwiridwe antchito komanso moyo wautumiki wamakina ndi zida. M'makampani apulasitiki, kuwonjezera kwa ufa wa Stearic acid kumatha kusintha magwiridwe antchito a pulasitiki, kukhala kosavuta kuumba, ndikuwonjezera kutha kwapamwamba komanso kusinthasintha kwazinthu zamapulasitiki. Kachiwiri, ufa wa stearic umakhalanso ndi emulsifying ndi kubalalitsa, ndipo umagwiritsidwa ntchito kwambiri muzodzoladzola ndi mankhwala. Itha kuthandizira zosakaniza zosiyanasiyana kusakanikirana bwino ndikuwongolera bwino komanso kukhazikika kwazinthu. Kuphatikiza apo, imagwiranso ntchito yofunika kwambiri pamakampani opanga mphira, omwe amatha kukulitsa mphamvu komanso kukana kwa abrasion kwa mphira.
Stearic acid ufa amagwiritsidwa ntchito m'njira zosiyanasiyana.
M'makampani apulasitiki, ndizofunikira kwambiri. Mwachitsanzo, popanga polyethylene (PE) ndi polypropylene (PP), ufa wa stearic umapangitsa kuyenda ndi kutulutsa katundu wa mapulasitiki, zomwe zimapangitsa kuti pakhale zokolola zambiri komanso khalidwe la mankhwala. Pokonza polystyrene (PS) ndi polyvinyl kolorayidi (PVC), kumawonjezera kuuma ndi kutentha kukana kwa mapulasitiki, kukulitsa ntchito zawo zosiyanasiyana.
Stearic acid ufa ndiwofunikanso kwambiri pazodzoladzola, pomwe amagwiritsidwa ntchito ngati emulsifier komanso chowongolera pakhungu monga mafuta odzola, mafuta odzola ndi milomo, kuti kapangidwe kake kakhale kofanana komanso kokhazikika. Mu zodzoladzola zamtundu, monga mthunzi wa maso ndi maziko, zimathandiza kupititsa patsogolo kumamatira ndi moyo wautali wa mankhwala, ndikupangitsa kuti ikhale yokongola kwambiri.
Makampani opanga mankhwala amapindulanso mokwanira ndi katundu wa stearic acid ufa. Mu mankhwala formulations, angagwiritsidwe ntchito ngati excipient ndi lubricant kuthandiza mankhwala kuti bwino zowumbidwa ndi kumasulidwa, ndi kusintha bioavailability wa mankhwala. Pakalipano, muzinthu zina za capsules, ufa wa stearic acid ungathenso kutenga nawo mbali pakudzipatula ndi kuteteza mankhwalawa.
M'makampani opangira mphira, ufa wa stearic acid ukhoza kulimbikitsa vulcanisation ya mphira ndikuwongolera kachulukidwe ka mphira, motero kumawonjezera mphamvu zamakina komanso kukana kukalamba kwa mphira. Kaya ndi matayala, zosindikizira za rabala kapena malamba onyamula mphira, ufa wa stearic umathandizira kwambiri kuwongolera ndi magwiridwe antchito awo.
Kuphatikiza apo, ufa wa stearic acid umagwira ntchito yofunika kwambiri pamafakitale a nsalu, zokutira ndi inki. M'makampani opanga nsalu, amatha kugwiritsidwa ntchito ngati chofewa komanso chothamangitsira madzi kuti azitha kumva bwino komanso kuchita bwino kwa nsalu. Mu zokutira ndi inki, izo bwino kubalalitsidwa ndi bata la inki ndi kumawonjezera gloss ndi adhesion wa zokutira.
Pomaliza, ufa wa stearic umagwira ntchito yofunika kwambiri m'makampani amakono ndi moyo ndi zinthu zake zapadera, magwero osiyanasiyana, magwiridwe antchito odabwitsa komanso machitidwe osiyanasiyana.
