Incamake y'ubumenyi bw'ikoreshwa ry'ibikoresho bihindura ingaruka bya PVC

(1) CPE

Polyethylene ifite chlorine (CPE) ni ifu ikomoka kuri chlorine ya HDPE mu gihe cy'amazi. Uko chlorine igenda yiyongera, HDPE ya kera ya crystalline ihinduka elastomer idahinduka. CPE ikoreshwa nk'igikoresho cyo gukomera muri rusange ifite chlorine iri hagati ya 25-45%. CPE ifite ahantu henshi hatandukanye kandi ibiciro biri hasi. Uretse ingaruka zayo zo gukomera, inarwanya ubukonje, irwanya ikirere, irwanya umuriro, kandi irwanya imiti. Kuri ubu, CPE niyo ihindura ingaruka cyane mu Bushinwa, cyane cyane mu gukora imiyoboro ya PVC n'impapuro zayo, kandi inganda nyinshi zikoresha CPE. Umubare w'inyongera muri rusange ni ibice 5-15. CPE ishobora gukoreshwa hamwe n'ibindi bikoresho byo gukomera, nka rubber na EVA, kugira ngo igere ku musaruro mwiza, ariko ibikoresho bya rubber ntibirwanya gusaza.

(2) ACR

ACR ni copolymer ya monomers nka methyl methacrylate na acrylic ester. Ni yo ihindura ingaruka nziza cyane yakozwe mu myaka ya vuba aha kandi ishobora kongera imbaraga z'ingaruka z'ibikoresho inshuro nyinshi. ACR ni iy'ihindura ingaruka z'imiterere y'igishishwa cy'ibanze, igizwe n'igishishwa kigizwe na polymer ya methyl methacrylate ethyl acrylate, na elastomer ya rubber ikozwe no guhuza na butyl acrylate nk'igice cy'uruhererekane rw'ibanze gikwirakwizwa mu gice cy'imbere cy'uduce. By'umwihariko ikwiriye guhindura ingaruka z'ibicuruzwa bya pulasitiki bya PVC kugira ngo bikoreshwe hanze, gukoresha ACR nk'ihindura ingaruka mu miterere y'inzugi n'amadirishya bya pulasitiki bya PVC bifite imiterere myiza yo gutunganya, ubuso bworoshye, kudashaza neza, no gukomera cyane mu mfuruka ugereranije n'izindi hindura, ariko igiciro kiri hejuru ya kimwe cya gatatu kurusha CPE.

(3) MBS

MBS ni copolymer igizwe na monomer eshatu: methyl methacrylate, butadiene, na styrene. Igipimo cy'ingufu cya MBS kiri hagati ya 94 na 9.5, kiri hafi y'igipimo cy'ingufu cya PVC. Kubwibyo, ihura neza na PVC. Ikiranga cyayo gikomeye ni uko nyuma yo kongeramo PVC, ishobora gukorwamo ibicuruzwa bibonerana. Muri rusange, kongeramo ibice 10-17 kuri PVC bishobora kongera imbaraga zayo z'ingufu inshuro 6-15. Ariko, iyo ingano ya MBS yongeweho irenga ibice 30, imbaraga z'ingufu za PVC ziragabanuka. MBS ubwayo ifite imikorere myiza y'ingufu, igaragara neza, kandi ikwirakwira hejuru ya 90%. Nubwo yongera imikorere y'ingufu, ntacyo igira ku yindi miterere ya resin, nko gukomera no kurekura igihe cyo kuruhuka. MBS irahenze kandi ikunze gukoreshwa hamwe n'ibindi bintu bihindura ingaruka nka EAV, CPE, SBS, nibindi. MBS ifite ubushobozi buke bwo kurwanya ubushyuhe no kurwanya ikirere, bigatuma idakoreshwa mu gihe kirekire hanze. Muri rusange ntabwo ikoreshwa nk'uburyo bwo guhindura ingaruka mu gukora imiterere y'inzugi n'amadirishya bya pulasitiki.

(4) SBS

SBS ni copolymer ya ternary block ya styrene, butadiene, na styrene, izwi kandi nka thermoplastic styrene butadiene rubber. Ni iya thermoplastic elastomers kandi imiterere yayo ishobora kugabanywamo ubwoko bubiri: ishusho y'inyenyeri n'umurongo. Igipimo cya styrene na butadiene muri SBS ahanini ni 30/70, 40/60, 28/72, na 48/52. Ikoreshwa cyane cyane nk'uburyo bwo guhindura ingaruka kuri HDPE, PP, na PS, hamwe n'ibice 5-15. Akamaro ka SBS ni ukunoza uburyo bwayo bwo kurwanya ingaruka ku bushyuhe buke. SBS ifite ubushobozi bwo kurwanya ikirere buke kandi ntikwiriye ku bicuruzwa bikoreshwa hanze igihe kirekire.

(5) ABS

ABS ni copolymer ya ternary ya styrene (40% -50%), butadiene (25% -30%), na acrylonitrile (25% -30%), ikoreshwa cyane cyane nk'imashini zikora pulasitiki kandi ikoreshwa no mu guhindura ingaruka za PVC, ifite ingaruka nziza zo guhindura ingaruka ku bushyuhe buke. Iyo ingano ya ABS yongeweho igeze ku bice 50, imbaraga z'ingaruka za PVC zishobora kungana n'iza ABS yonyine. Ingano ya ABS yongeweho muri rusange ni ibice 5-20. ABS ifite ubushobozi buke bwo guhangana n'ikirere kandi ntikwiriye gukoreshwa igihe kirekire hanze mu bicuruzwa. Muri rusange ntikoreshwa nk'imashini ihindura ingaruka mu gukora inzugi n'amadirishya bya pulasitiki.

(6) Eva

EVA ni copolymer ya ethylene na acetate ya vinyl, kandi gushyiramo acetate ya vinyl bihindura imiterere ya kristali ya polyethylene. Ingano ya acetate ya vinyl iratandukanye cyane, kandi igipimo cyo kurekura cya EVA na PVC kiratandukanye, bigatuma bigorana kubona ibicuruzwa bibonerana. Kubwibyo, EVA ikunze gukoreshwa hamwe n'izindi resins zirwanya ingaruka. Ingano ya EVA yongewemo ni munsi ya 10.
