Guddiga PP waa fasalka PP-ga, bay'ada u habboon, u fiican, cad waa waxoogaa hufan, dhinacyaduna waxay leeyihiin dhalaal cad. Qiimaha cad ee cadcad ayaa ka sarreeya kan cad. Midabka guddiga PP ee fasalka A waa mid hufan, midabka fasalka B waa mid cad cad, waxaana jira cidhifyo yar oo dhinac ah, oo hal ilmada ka soo baxa.
Faa'iido:
1. Hurdo adag iyo dhibic dhalaalaya oo sarreeya.
2, heerkulka kuleylka kuleylka kuleylka ah (100 ° C), daahfurnaan hooseeya, gaboobay oo hooseeya, adag.
3. Xoogga saamaynta ayaa sarreeya, iyo xoogga PP-gu wuxuu ku kordhiyaa kororka waxyaabaha ku jira ethylene.
4. Dusha sare ee salka wanaagsan iyo is-caabbinta xoqista. Gudiga PP-ka waxaa wax laga beddelay iyadoo lagu daro fiber galaas, bir lagu daro ama caag heerkul ah. Heerka qulqulka Mr Fries wuxuu u ordayaa 1 ilaa 40. Caabbitaanka saameynta ee sheyga MFR ee hooseeya ayaa ka fiican. Way fiicantahay laakiin xoogga kordhinta ayaa hooseysa. Sidaa darteed, inta badan ma jiraan dhibaato ku saabsan jawiga is-xakameynta deegaanka ee guddiga PP.
5. Qiyaasta burburka sare. Maaddaama xaashida PP-ka ee PP ay tahay walxood-quseeya, heerka burburka guud ahaan waa 1.8 illaa 2.5%. Iyo jihada isku-darka ah ee ka-goynta ayaa aad uga fiican agabyada sida PE-HD.

Shirkaddeenu waxay si qoto dheer ugu mashquulsan tahay balaastigga injineerinka waxqabadka sare, waxaana ka go'an inay siiso xalka maaddada hal-abuurka ah ee warshadaha soo-saarka ee ugu sareeya. Alaabooyinkayaga ugu muhiimsan waxaa ka mid ah go'yaal caag ah oo dhameystiran sida poloyoxymymerene (pom), polycharbonate (polychertonenenene (polyphertones), iwm), polyphertones (polythertone), phenole-ka (phenethertone) iyo gudiga galaaska galaaska ephox. Iyada oo leh guryo aad u wanaagsan sida caabbinta heerkulka sare, iska caabbinta, iyo xoog sare, alaabooyinkeena ayaa si weyn loogu adeegsadaa gawaarida tamarta cusub, mashiinka elektaroonigga ah, mashiinnada warshadaha, aerospace iyo beero kale.
