Wothandizira wawunthu ndi mtundu wazowonjezera zatsopano zomwe zingakuthandizenipo monga kuwonekera, mphamvu, mphamvu yosokoneza, kukana mphamvu, ndi kusintha kwa crystalsin ya ma resin. Amagwiritsidwa ntchito kwambiri pakupanga mapulaji osakwanira a polyethylene ndi polypropylene muokhacho, zida zapakhomo, zamagetsi, ndi minda yamagetsi. Mwachitsanzo, wothandizira wazogulitsa ndi chinthu chofunikira kwambiri popanga ma rention okwera kwambiri monga ma setpropylene polypropylene, ndikusintha kwa ma crystalline polypleve. Powonjezera ntchito zapadera, zitsulo zokhala ndi mawonekedwe osinthika, okhwima, komanso kulimba mtima kumatha kupangidwa. Ndi kuwonjezeka kwakukulu kwa polypropylene yokwera kwambiri yomwe imafunikira kuwonjezera kwa othandizira a batirative and ortiry, zomwe zingatheke kuti ikhale ndi msika wothandiza.
Pali mitundu yambiri yaothandizira azogulitsa, ndipo ntchito zawo zogulitsa zikupitilirabe. Malinga ndi mitundu yosiyanasiyana ya kristal yolumikizidwa ndi othandizira a scractiot, amatha kugawidwa m'magulu othandizira a α-cry-crystalline. Ndipo ma Crystrine othandizira a ma crystalline amatha kuphatikizidwanso mu avoric, organic, ndi ma polymer kutengera kusiyana kwawo. Othandizira zachilengedwe makamaka amaphatikizapo othandizira oyambirirawo monga talc, calcium oxide, ndi Mica, omwe ndi otsika mtengo komanso osavuta kuwonekera komanso pansi. Othandizira opangira zachilengedwe makamaka amaphatikiza makamaka carboxylic acid mchere, sorbite benzolehyde zotumphukira, ndi mitundu yotsika kwambiri, ndipo yayamba kukhala yotsogola kwambiri komanso Padziko lonse lapansi. Othandizira a polymer a polymec amakhala othandizira a polymection, monga polyvinycyclone ndi polyvinyllliny. Othandizira othandizira a β-crystalline makamaka ndi mitundu iwiri: magawo ochepa a compectic ndi zida zatsemphana, ndipo zopangidwa ndi zitsulo zokhala ndi zitsulo zochokera ku gulu la nthawi yayitali. Othandizira a β-crystalline onetsetsani kutentha kwa mafuta pomwe kumawongolera kukana kwawo.
Zitsanzo za Ntchito Zogwirira Ntchito ndi Kugwiritsa Ntchito Kwa Othandizira
| Malo | Kufotokozera kwa ntchito | Mapulogalamu |
| Wothandizila EXTECTE | Imatha kusintha kwambiri za utomoni, kuchepetsa haze ndi 60%, Ndikuwonjezera kutentha kwa kutentha ndi kutentha kwa crystallization a rentin ndi 5 ~ 10 ℃, ndikusintha modulus modulus ndi 10% ~ 15%. Ikufupikitsanso kuzungulira, Imakulitsa mphamvu yopanga, ndikukhalabe bata. | Ma setlet atlex polypropylene (kapena mmwamba mitu polypropylene) |
| Zovuta Zothandizira | Itha kusintha kwambiri makina a utoto wa utomoni, Ndi kuwonjezeka kosasinthasintha modulus ndi kuwerama mphamvu zoposa 20%, komanso kuchuluka kwa kutentha kutentha kwa 15 ~ 25 ℃. Palinso kusintha kokwanira ndi koyenera kumayiko osiyanasiyana monga kutentha kwa crystallization ndi kukhudza mphamvu, chifukwa chokwanira komanso kuchepetsedwa kuwonongeka kwa chiwonetsero cha malonda. | Mndandanda wambiri wosungunuka polypropylene, wokhwima kwambiri, wamphamvu kwambiri, komanso wamtali wa clyproplene, wosinthidwa polypropylene zinthu zowonda kwambiri |
| β-crystalline yolumikizira othandizira | Imatha kupangitsa kuti mapangidwe a β-crystalline polypropylene, ndi ma crystalline kutembenuka kwa ma crystalline a 80%, Kuwongolera kwambiri mphamvu ya mphamvu ya polypropylene ulen, Ndipo kupititsa patsogolo kumatha kufikira nthawi zopitilira 3. | Mndandanda wambiri wa Sungunule Polypropylene, wokhwima kwambiri, wamphamvu kwambiri, komanso wamtali kwambiri polyproplene, β-crystalline polypropylene |
