utomoni wa polypropylene chifukwa uli ndi kukhazikika bwino komanso kukana kutentha, ndipo kusinthidwa kumatanthauza kulemera, chifukwa pang'onopang'ono m'malo mwa mapulasitiki a uinjiniya, omwe amagwiritsidwa ntchito kwambiri pamagalimoto, zida zamagetsi ndi nyumba ndi magawo ena.

Makamaka pa copolymerization polypropylene utomoni, ndi m'kupita kwa ndondomeko kupanga ndi chothandizira luso, amapereka mankhwala kwambiri kwambiri mabuku ntchito Koma chifukwa cha mmene anali kusonkhana kwa propylene kupanga ali ndi mavuto aakulu luso, makamaka mbali monga mankhwala toughness ndi rigidity. zamadzimadzi, nawonso sangakhoze kwathunthu kudzaza mokwanira m'madera ena kufunika, choncho ayeneranso pamaziko a alipo mtundu zotsatira copolymer polypropylene pambuyo kusinthidwa, ndicho kudzera kuwonjezera nucleating wothandizila elastomer inorganic filler kukwaniritsa zinthu monga mkulu kukhazikika.

Kulimba kwa zida za polypropylene zolimba kwambiri komanso kutulutsa kwamadzimadzi kwambiri nthawi zambiri kumasinthidwa ndikuwonjezera nucleating agent kapena inorganic filler.Ndi kuwonjezera kwa inorganic filler monga calcium carbonate, talcum powder, mica, diatomite, etc., kupindika kwa polypropylene resin The flexural mphamvu ndi flexural zotanuka modulus kukula pang'onopang'ono, koma nthawi yomweyo, elongation ndi mphamvu mphamvu ya polypropylene adzakhala. kuchepetsedwa, ndipo mtundu ndi kuchepa kwa zinthu za polypropylene zidzakhudzidwa.Kuphatikiza apo, kuwonjezera kuchuluka kwa zodzaza ma inorganic kumathandizira kachulukidwe wazinthu, kuletsa zopepuka zazinthu, makamaka pankhani yamagalimoto.

M'zaka zaposachedwapa, ntchito nucleating wothandizila polypropylene pang'onopang'ono kuchuluka.Zomera zambiri za petrochemical zimawonjezera nyukiliya munjira yopangira granulation popanga utomoni wa polypropylene.Kuwonjezera kwa nucleating wothandizira sikungokhala ndi zotsatirapo zoipa pa mtundu wa polypropylene, komanso kungathandize kusintha kutentha kukana ndi glossiness wa polypropylene utomoni.5%, ngakhale kuchuluka kwa kuwonjezera ndi kochepa, koma chifukwa cha mtengo wa nucleating wothandizira ndi okwera mtengo (malinga ndi khalidwe la mankhwala ndi mlingo luso, mtengo nthawi zambiri mu makumi zikwi mazana asanu zikwi), adzawonjezera mtengo wa polypropylene utomoni matani mazana angapo yuan.

Kupangidwa kwa polypropylene kumapangidwa kuchokera kuzinthu zotsatirazi potengera kulemera kwake:

polypropylene utomoni100;

Kutentha kokhazikika 0,05 ~ 2;

Stearate zitsulo mchere 0,02 ~ 0,5;

Inorganic filler 0.05 ~ 3;

Organic nucleating wothandizira 0.01 ~ 0.2.

Polypropylene resin composite pogwiritsa ntchito polypropylene resin, matenthedwe stabilizer, stearic acid, zitsulo zamchere, zodzaza ndi organic ndi pang'ono za nucleating wothandizila anali osakaniza granulation kukonzekera, kulimba mkulu, mkulu kutentha kukana ndi mtengo wotsika mtengo, kukonzekera luso ndi losavuta, polypropylene utomoni. kompositi angagwiritsidwe ntchito magalimoto, zipangizo zapakhomo ndi nyumba ndi zina.
