ʻO ka polypropylene resin no ka mea he maikaʻi kona rigidity a me ka wela, a ma hope o ka hoʻololi ʻana ʻo ia ka waiwai, no ka mea, ua hoʻololi mālie kēia i kekahi mau ʻenekinia plastics, hoʻohana nui ʻia i ka automotive, nā mea uila a me ka hale a me nā kula ʻē aʻe.

ʻOi aku ka maikaʻi ma ka copolymerization polypropylene resin, ma ka holomua o ka hana hana a me ka ʻenehana catalyst, hāʻawi i nā huahana i ʻoi aku ka maikaʻi o ka hana holoʻokoʻa. ʻAʻole hiki ke hoʻopiha piha ʻia i kekahi mau wahi o ka noi, no laila pono nō hoʻi ma ke kumu o ka hopena brand copolymer polypropylene ma hope o ka hoʻololi ʻana, ʻo ia hoʻi ma o ka hoʻohui ʻana i ka mea hoʻopihapiha elastomer inorganic filler e hoʻokō i nā mea e like me ka rigidity kiʻekiʻe.

ʻO ka rigidity o nā mea polypropylene me ka paʻakikī kiʻekiʻe a me ka wai kiʻekiʻe e hoʻomaikaʻi pinepine ʻia e ka hoʻohui ʻana i ka nucleating agent a i ʻole ka mea hoʻopihapiha inorganic.Me ka hoʻohui ʻana o ka mea hoʻopihapiha inorganic e like me ka calcium carbonate, talcum powder, mica, diatomite, etc., ke kulou ʻana o ka resin polypropylene. e hoʻemi ʻia, a e hoʻopilikia ʻia ke kala a me ka emi ʻana o nā huahana polypropylene.Eia kekahi, ʻo ka hoʻohui ʻana o ka nui o nā mea hoʻopihapiha inorganic e hoʻomaikaʻi i ka nui o nā mea, kaohi ʻana i ka māmā o nā huahana, ʻoi aku hoʻi i ke kahua o nā noi automotive.

I nā makahiki i hala iho nei, ua piʻi mālie ka noi ʻana o ka mea nucleating agent i ka polypropylene.Nui nā mea kanu petrochemical e hoʻohui i ka mea nucleating agent i ka hana granulation o ka hana ʻana i ka resin polypropylene.ʻO ka hoʻohui ʻana o ka mea nucleating ʻaʻole wale ka hopena ʻino i ke kala o ka polypropylene, akā hiki ke hoʻomaikaʻi i ka pale wela a me ka nani o ka polypropylene resin.5%, ʻoiai he liʻiliʻi ka nui o ka hoʻohui, akā ma muli o ke kumukūʻai o ka nucleating agent he pipiʻi (e like me ka maikaʻi o ka huahana a me ka pae ʻenehana, ʻo ke kumukūʻai maʻamau i loko o nā ʻumi tausani a ʻelima haneli tausani), e hoʻonui i ke kumukūʻai o polypropylene resin tona o kekahi mau haneri yuan.

Hana ʻia ka haku mele polypropylene mai nā mea maka ma ke kaupaona:

polypropylene resin100;

Mea hoʻopaʻa wela 0.05 ~ 2;

Stearate metala paʻakai 0.02 ~ 0.5;

Mea hoʻopihapiha hoʻopihapiha 0.05 ~ 3;

Mea hoʻolalelale kino 0.01 ~ 0.2.

ʻO ka polypropylene resin composite ma ka hoʻohana ʻana i ka polypropylene resin, thermal stabilizer, stearic acid, nā paʻakai metala, inorganic filler a me kahi mea liʻiliʻi o ka nucleating agent i hui pū ʻia i ka hoʻomākaukau granulation, kiʻekiʻe rigidity, kiʻekiʻe wela a me nā kumu kūʻai haʻahaʻa, maʻalahi ka ʻenehana hoʻomākaukau, ka polypropylene resin. Hiki ke hoʻohana ʻia ka composite i nā kaʻa, nā mea hana hale a me ka hale a me nā ʻano ʻē aʻe.
