PP (polypropylene) ipurasitiki yakajairwa zvinhu zvine kunaka kwekupisa, kuramba kwemakemikari uye kushomeka. MFPP (modified polypropylene) chinhu chakagadziridzwa chepolypropylene chine simba rakasimba uye kuoma. Pazvinhu zviviri izvi, chinyorwa ichi chinopa yakakurumbira sainzi sumo maererano neyakagadzirwa masosi, maitiro ekugadzirira, maitiro, uye mashandisirwo endima.
1. Raw material sosi yePP neMFPP Iyo mbishi yePP inogadzirwa ne polymerizing propylene mu petroleum. Propylene chigadzirwa che petrochemical chinowanikwa zvakanyanya kuburikidza nekupwanya maitiro mumafinefineries. Modified polypropylene MFPP inovandudza mashandiro ayo nekuwedzera modifiers kune yakajairwa PP. Aya magadzirirwo anogona kuve ekuwedzera, mafirita kana mamwe madhizaini anoshandura chimiro chepolymer uye kuumbwa kuti chipe zvirinani zvemuviri nemakemikari zvimiro.
2. Kugadzirira nzira yePP neMFPP Kugadzirira kwePP kunonyanya kuwanikwa kuburikidza nepolymerization reaction. Propylene monomer inoshongedzwa kuita polymer cheni yehurefu hwakati kuburikidza nekuita kwekatani. Iyi nzira inogona kuitika nguva dzose kana zvishoma nezvishoma, pakupisa kwakanyanya uye kumanikidzika. Kugadzirira kweMFPP kunoda kusanganisa modifier uye PP. Kuburikidza nekunyunguduka kusanganisa kana kugadzirisa kusanganisa, iyo modifier inoparadzirwa zvakaenzana muPP matrix, nekudaro ichivandudza zvinhu zvePP.
3. Hunhu hwePP uye MFPP PP ine kunaka kwekudzivirira kupisa uye kugadzikana kwemakemikari. Ipurasitiki inopenya ine imwe kuoma uye kuoma. Nekudaro, kusimba uye kuoma kweyakajairika PP kwakadzikira, izvo zvinotungamira kuunzwa kwezvinhu zvakagadziridzwa seMFPP. MFPP inowedzera mamwe ma modifiers kuPP kuita kuti MFPP ive nani simba, kuoma uye kukanganisa kuramba. Ma modifiers anogona zvakare kuchinja thermal conductivity, magetsi zvivakwa uye kuramba kwemamiriro ekunze kweMFPP.
4. Minda yekushandiswa kwePP uye MFPP PP inoshandiswa zvakanyanya uye inowanzoshandiswa mumidziyo, fenicha, midziyo yemagetsi uye zvimwe zvigadzirwa muupenyu hwezuva nezuva. Nekuda kwekudzivirira kwayo kupisa uye kushomeka kwemakemikari, PP inoshandiswawo mumapombi, midziyo, mavharuvhu nemimwe michina muindasitiri yemakemikari. MFPP inowanzo shandiswa mumashandisirwo anoda simba repamusoro uye kuomarara, senge zvikamu zvemotokari, zvigadzirwa zvemagetsi casings, zvekuvakisa, nezvimwe.
Mukupedzisa, PP neMFPP zvinhu zviviri zvakajairika zvepurasitiki. PP ine hunhu hwekupisa kupisa, makemikari corrosion kuramba uye yakaderera density, uye MFPP yakagadzirisa PP pahwaro uhwu kuti iwane simba riri nani, kuomarara uye kukanganisa kuramba. Izvi zvinhu zviviri zvinoita basa rakakosha munzvimbo dzakasiyana dzekushandisa, zvichiunza nyore uye kusimudzira kuhupenyu hwedu uye akasiyana maindasitiri minda.
