I-HIPS isifinyezo sesiNgisi se-resin eqinile ye-polystyrene, impahla eluhlaza eyinhloko yi-styrene, enokuqina okuphezulu, ukumelana nomthelela ophezulu, ukuqina kobukhulu, ukubunjwa okulula nokucutshungulwa nezinye izici eziningi, ingasetshenziswa kabanzi ezintweni zikagesi zasendlini, izinsimbi nezinsimbi. , amathoyizi,ukupakisha alahlwayo, inkundla yokwakha.Ukumelana nomthelela we-styrene kubi, futhi imikhiqizo yayo ishwabene futhi iphuke kalula ngokushayisana.Ukwengeza izinhlayiya zenjoloba ye-styrene butadiene ku-styrene kungathuthukisa ngempumelelo ukumelana kwayo komthelela, futhi izinhlayiya zenjoloba ze-butadiene ezivame ukusetshenziswa yi-butadiene, enokumelana nomthelela omuhle kakhulu.

Njengamanje kunezindlela ezimbili zokulungiselela i-polystyrene engazweli nomthelela, okuyindlela yokuhlanganisa kanye nendlela ye-graft copolymerization.Indlela yokuhlanganisa, okokuqala, ingxube ye-butadiene ne-styrene ngokulingana nengxube, bese ingxube ku-extruder ihlanganiswe ngokulinganayo, ikhiphe ukupholisa kwefilimu elincanyana, futhi ekugcineni isikwe phakathi.AMAHIPSizingcezu nge-shear, inqubo kufanele inake ngokukhethekile ingxube ihlanganiswe ngokulinganayo.

Endleleni ye-graft copolymerisation, izinhlayiya ze-butadiene zincibilika ku-styrene monomer, futhi ukusabela kwe-copolymerization kwenzeka ngosizo lwe-catalyst peroxide, futhi umkhiqizo we-copolymerization ekugcineni ufakwa ku-extruder ukuze uthole i-granulation.Empeleni, ipulasitiki ye-HIP kaningi kanye ne-ABS resin yezinto ezihambisanayo, impahla ye-HIPS ishibhile kune-ABS resin, kodwa izakhiwo zemishini ziphansi kune-ABS resin, imboni yezokwakha izosekelwe enanini lakho kokubili imakethe yokuthengwa kwempahla, ngakho-ke ipulasitiki ye-HIPS amanani ayashintshashintsha nenani leI-ABS, uma izintengo ze-ABS ziphezulu, zizoqhuba isidingo semakethe ye-HIPS, yiqiniso, umthelela we-HIPS Izintengo zePlastiki ziyisici esiyinhloko se-styrene material, ukunikezwa kwamanje kwe-styrene kuhlala kuzinzile, isidingo esingaphansi komfula sijwayelekile, intengo izinzile. ukuqeda.Ngokuhamba kwesikhathi, umthamo walo nyaka wokukhiqiza i-polypropylene ulinganiselwe, futhi ukukhiqizwa kwedivayisi yonyaka ozayo kulindeleke ukuthi kubambezeleke, umbono jikelele, ukuhlinzekwa kwezimpahla namanje akwanele, kodwa eminyakeni emibili edlule isidingo esikhuphukayo somfula siyehla, umbono jikelele, imakethe kulindeleke ukuthi ikhuphuke, kodwa izinzile.Lokhu kubonisa ukuthi uhlangothi lwezindleko alunayo idrayivu enhle.Eminyakeni emibili edlule, isidingo semakethe yezinto zikagesi zaseChina saqala ukwehla kancane kancane, kodwa ngokusekelwe kudatha enkulu, ubuchwepheshe bobuhlakani bokwenziwa, imakethe yangaphambili ingase ingenise isizini yamagagasi, okuzoqhuba ngempumelelo isidingo semakethe yezinto ezibonakalayo, isikhashana- I-term demand side inzima ukuba nentuthuko enkulu, ngakho uhlangothi lwesidingo lunegethivu.
