Hauv kev teb rau lub tswv yim kev txhim kho kom ruaj khov, KKS tau siv hom tshiab PP (polypropylene) hauv kev tsim cov thoob dej khov, siv cov txheej txheem tsim khoom tshiab. Peb cov thoob dej khov tshiab tam sim no muaj 30 feem pua ​​​​cov ntsiab lus siv dua.

Lub ntiajteb txawj nqus tshwj xeeb ntawm cov khoom PP: 0.9-0.91 g / cm3, uas yog ze li ntawm 23 feem pua ​​​​tshaj dua li nws cov thawj coj, thiab tam sim no yog cov khoom siv yooj yim tshaj plaws. Moulding shrinkage: 1. Nws muaj cov khoom siv hluav taws xob zoo thiab muaj hluav taws xob ntau zaus, thiab tsis cuam tshuam los ntawm cov av noo. Cov kua qaub thiab alkali organic solvents tsis tshua muaj txiaj ntsig rau nws, thiab feem ntau yog siv hauv PP khob, basins, thiab lwm yam, uas muaj kev nyab xeeb thiab txhim khu kev qha ntau dua li cov ntaub ntawv ABS siv ua ntej.

Polypropylene kuj suav nrog copolymer ntawm propylene nrog me me ntawm ethylene. Feem ntau translucent xim tsis muaj xim, tsis muaj ntxhiab thiab tsis muaj tshuaj lom. Vim yog cov qauv tsis tu ncua thiab siab crystallization, lub melting point yog siab li 167 degree C, tshav kub tsis kam, thiab cov khoom yuav sterilized los ntawm chav, uas yog nws zoo heev zoo.

PP cov ntaub ntawv tau yooj yim decomposed nyob rau hauv tej yam kev mob. Vim qhov no feature, KKS yas chim thiab lwm yam khoom yuav decomposed thiab recycled rau lwm yam kev sib cais, uas yog conducive rau lub sustainable kev loj hlob thiab kev siv ntawm cov peev txheej.
