ʻO ka pepa PP flame-retardant he pepa plastik i hana ʻia me ka resin PP, me nā mea hoʻohui hana like ʻole i hoʻohui ʻia ma o ka extrusion, calendering, cooling, cutting a me nā kaʻina hana ʻē aʻe. ʻO ka pepa PP flame retardant he mea semi-crystalline. ʻOi aku ka paʻakikī ma mua o ka PE a he kiʻekiʻe ke kiko heheʻe. No ka mea, he palupalu loa ka mahana homopolymer PP ma luna o 0C, he nui nā mea PP kalepa he mau copolymers random me ka 1-4% ethylene content a i ʻole nā ​​​​block copolymers me ka ʻike ethylene kiʻekiʻe. Loaʻa i nā mea Copolymer PP kahi mahana distortion wela haʻahaʻa (100°C), haʻahaʻa transparency, haʻahaʻa gloss, a me ka haʻahaʻa rigidity, akā he ikaika hopena ikaika. No laila, pehea e ʻike ai i ka maikaʻi o ka pepa PP flame retardant?

1. E nānā i kona ʻōlinolino o ka ʻili. ʻO ka ʻōlinolino maikaʻi ʻole he palaki hana hou ʻia.

2. E nānā i kona paʻakikī. He paʻakikī maikaʻi loa ka pepa PP pale ahi maka maʻemaʻe a hiki ke pelu iki ʻia.

3. E nānā i ka ʻili ʻoki. Ma hope o ka ʻoki ʻana i ka palaki hana hou ʻia, e loaʻa ana nā ʻano ʻōpala like ʻole i nā kala like ʻole.

4. E nānā i kona mānoanoa. ʻO ka mānoanoa o ka PP polypropylene he 0.92~0.93. ʻO nā mea a pau e lana ana ma luna o ka wai he polypropylene.

5. Hoʻomehana ʻia a hoʻopili ʻia ka pepa PP pale ahi. Puka mai ka uahi i ka wā e hoʻopili ai i ka plastik hana hou ʻia.

6. Ka hoʻoili māmā, ʻaʻole maikaʻi ka hoʻoili māmā o nā plastik hana hou ʻia.

7. ʻOi aku ka paʻakikī o ka palaki hana hou ʻia.

8. ʻO ka nui o ka pepa PP e pale ana i ke ahi, e hoʻolei i loko o ka wai e ʻike inā e lana ana ma luna o ka wai, ʻo ka hapa nui o ka wai hana hou e piholo i lalo.
