polypropilene resin kuko ifite ubukana bwiza nubushyuhe bukabije, kandi nyuma yo guhinduka bisobanura ubukire, kuko ibi bigenda bisimbuza buhoro buhoro plastiki yubuhanga, ikoreshwa cyane mumamodoka, ibikoresho byamashanyarazi ningo nizindi nzego

By'umwihariko kuri copolymerisation polypropilene resin, mugutezimbere ibikorwa byumusaruro hamwe nikoranabuhanga rya catalizator, biha ibicuruzwa imikorere myiza yuzuye ariko Ariko kubera ingaruka zahurijwe hamwe kubyara umusaruro wa propylene bifite ibibazo bikomeye bya tekiniki, cyane cyane mubice nko gukomera kwibicuruzwa no gukomera. ubuvanganzo, nabwo ntibushobora kuzura byuzuye mubice bimwe bisabwa, kubwibyo rero birakenewe kandi hashingiwe ku ngaruka zisanzweho za kopi ya pololymer polypropilene nyuma yo guhinduka, cyane cyane binyuze mu kongera nucleating agent elastomer inorganic kuzuza kugirango ugere kubintu nkibikomeye.

Ubukomezi bwibikoresho bya polypropilene hamwe nubukomezi bwinshi hamwe n’amazi menshi mubisanzwe bitezimbere wongeyeho nucleating agent cyangwa uwuzuza ibintu.Hiyongereyeho kuzuza ibintu bidasanzwe nka calcium karubone, ifu ya talcum, mika, diatomite, nibindi, kunama kwa polypropilene resin Imbaraga za flexural na flexural elastique modulus ziyongera buhoro buhoro, ariko mugihe kimwe, kurambura n'ingaruka za polypropilene bizagenda kugabanuka, kandi ibara no kugabanuka kwibicuruzwa bya polypropilene bizagira ingaruka.Byongeye kandi, kongeramo umubare munini wuzuza ibinyabuzima bizamura ubwinshi bwibikoresho, bigabanya uburemere bwibicuruzwa, cyane cyane mubijyanye n’imodoka

Mu myaka yashize, ikoreshwa rya nucleating agent muri polypropilene ryagiye ryiyongera buhoro buhoro.Ibimera byinshi bya peteroli byongera nucleating agent mugikorwa cyo guhunika kubyara polipropilene.Kwiyongera kwa nucleating agent ntabwo bigira ingaruka mbi gusa kumabara ya polypropilene, ariko kandi birashobora kunoza ubushyuhe hamwe nuburabyo bwa polipropilene.5%, nubwo umubare winyongera ari muto, ariko bitewe nigiciro cya agent nucleating ihenze (ukurikije ubuziranenge bwibicuruzwa nu rwego rwa tekiniki, igiciro ubusanzwe kiri mubihumbi icumi kugeza ku bihumbi magana atanu), bizongera ikiguzi cya polypropilene resin toni yamajana.

Imiterere ya polypropilene ikozwe mubikoresho bikurikira bikurikira kuburemere:

polipropilene100;

Ubushyuhe bwo gushyushya 0.05 ~ 2;

Koresha umunyu w'icyuma 0.02 ~ 0.5;

Kuzuza ibinyabuzima 0.05 ~ 3;

Umubiri wa nucleating agent 0.01 ~ 0.2.

Polypropilene resin ikomatanya ukoresheje polipropilene resin, stabilisateur yumuriro, aside stearic, umunyu wibyuma, kuzuza inorganic hamwe na nucleating agent nkeya byari bivanze no gutunganya granulation, gukomera cyane, kurwanya ubushyuhe bwinshi hamwe ninyungu nke, tekinoroji yo gutegura iroroshye, polypropilene resin guhuriza hamwe birashobora gukoreshwa mumodoka, ibikoresho byo murugo hamwe murugo nizindi nzego.
