Imvelaphi yobugcisa

i-polypropylene resin ngenxa yokuba inobulukhuni obuhle kunye nokumelana nobushushu, kwaye emva kokuguqulwa kuthetha ubutyebi, kuba oku kutshintsha ngokuthe ngcembe ezinye iiplastiki zobunjineli, ezisetyenziswa ngokubanzi kwiimoto, izixhobo zombane kunye nendlu kunye namanye amacandelo.

Ngokukodwa kwi-resin ye-polypropylene copolymerization, ngenkqubela phambili yenkqubo yemveliso kunye nobuchwepheshe be-catalyst, inika iimveliso ezigqwesileyo ngakumbi ukusebenza okubanzi. ubungakanani bemali, kwakhona ayikwazi ngokupheleleyo ngokupheleleyo ngokwaneleyo kwezinye iindawo zemfuno, ngoko ke kwakhona imfuneko ngesiseko ekhoyo brand impembelelo copolymer polypropylene emva ukuguqulwa, oko kukuthi ngokongeza i-nucleating agent elastomer inorganic filler ukuphumeza imathiriyeli ezifana nokuqina okuphezulu.

Ukuqina kwezixhobo ze-polypropylene ezinobunzima obuphezulu kunye ne-fluidity ephezulu ngokuqhelekileyo kuphuculwe ngokudibanisa i-nucleating agent okanye i-inorganic filler.Ukongezwa kwe-inorganic filler efana ne-calcium carbonate, i-talcum powder, i-mica, i-diatomite, njl., ukugoba kwe-polypropylene resin Amandla aguquguqukayo kunye ne-flexural elastic modulus yanda ngokuthe ngcembe, kodwa kwangaxeshanye, ukomelela kunye namandla empembelelo ye-polypropylene iya kuba njalo. kuncitshiswe, kwaye umbala kunye nokuncipha kweemveliso ze-polypropylene ziya kuchaphazeleka.Ngapha koko, ukongezwa kwenani elikhulu leefayili ze-inorganic kuya kuphucula ukuxinana kwezixhobo, kuthintelwe ukukhaphukhaphu kweemveliso, ngakumbi kwibala lezicelo zeemoto.

Kwiminyaka yakutshanje, ukusetyenziswa kwe-agent ye-nucleating kwi-polypropylene kuye kwanda ngokuthe ngcembe.Izityalo ezininzi ze-petrochemical zongeza i-agent ye-nucleating kwinkqubo ye-granulation yokuvelisa i-polypropylene resin.Ukongezwa kwe-agent ye-nucleating ayinayo impembelelo embi kumbala we-polypropylene, kodwa kunokuphucula ukuchasana nokushisa kunye nokukhanya kwe-polypropylene resin.I-5%, nangona inani lokongezwa lincinci, kodwa ngenxa yexabiso le-agent ye-nucleating libiza (ngokomgangatho wemveliso kunye nenqanaba lobugcisa, ixabiso lidla ngokuhlala kwishumi lamawaka ukuya kumakhulu amahlanu amawaka), liya kwandisa iindleko polypropylene resin iitoni ezingamakhulu aliqela yuan.

Ukwakheka kwepolypropylene kwenziwa kwezi zinto zilandelayo zobunzima:

polypropylene resin100;

Ukuzinzisa ubushushu 0.05 ~ 2;

Stearate metal ityuwa 0.02 ~ 0.5;

Inorganic filler 0.05 ~ 3;

I-agent ye-nucleating ye-Organic 0.01 ~ 0.2.

I-polypropylene resin composite ngokusebenzisa i-polypropylene resin, i-thermal stabilizer, i-stearic acid, iityuwa zetsimbi, i-inorganic filler kunye nenani elincinci le-nucleating agent yayixutywe ukulungiswa kwe-granulation, ukuqina okuphezulu, ukumelana nobushushu obuphezulu kunye nenzuzo yeendleko eziphantsi, iteknoloji yokulungiselela ilula, i-polypropylene resin I-composite ingasetyenziswa kwiimoto, kwizixhobo zendlu kunye nekhaya kunye nezinye iindawo.
