Inshamake yubumenyi bwogukoresha bwa PVC impinduka

(1) CPE

Chlorine polyethylene (CPE) nigicuruzwa cyifu ya chlorine yahagaritswe ya HDPE mugice cyamazi. Hamwe no kwiyongera kwa chlorine, ubwambere kristaline HDPE ihinduka buhoro buhoro amorphous elastomer. CPE ikoreshwa nkibikoresho bikaze muri rusange ifite chlorine ya 25-45%. CPE ifite amasoko atandukanye hamwe nibiciro biri hasi. Usibye ingaruka zayo zikomeye, inagira ubukonje bukabije, kurwanya ikirere, kurwanya umuriro, hamwe no kurwanya imiti. Kugeza ubu, CPE niyo yiganjemo impinduka mu Bushinwa, cyane cyane mu gukora imiyoboro ya PVC na profile, kandi inganda nyinshi zikoresha CPE. Amafaranga yiyongereye muri rusange ni 5-15. CPE irashobora gukoreshwa ifatanije nibindi bikoresho bikaze, nka reberi na EVA, kugirango bigerweho neza, ariko inyongeramusaruro ntishobora kurwanya gusaza.

(2) ACR

ACR ni copolymer ya monomers nka methyl methacrylate na acrylic ester. Nibintu byiza byahinduye byahinduwe mumyaka yashize kandi birashobora kongera imbaraga zingaruka zibikoresho inshuro mirongo. ACR ni iy'ingaruka zo guhindura imiterere-shitingi, igizwe nigikonoshwa kigizwe na methyl methacrylate ethyl acrylate polymer, hamwe na rubber elastomer ikorwa no guhuza na butyl acrylate nkigice cyuruhererekane rwagabanijwe mugice cyimbere cyibice. By'umwihariko bikwiranye no guhindura ingaruka za plastike ya PVC kugirango ikoreshwe hanze, ukoresheje ACR nkimpinduka zingaruka mumuryango wa plastike ya PVC hamwe nidirishya ryamadirishya bifite ibiranga imikorere myiza yo gutunganya, hejuru neza, kurwanya gusaza, hamwe nimbaraga zo gusudira cyane ugereranije nabandi bahindura , ariko igiciro kiri hafi kimwe cya gatatu kirenze CPE.

(3) MBS

MBS ni copolymer ya monomers eshatu: methyl methacrylate, butadiene, na styrene. Ikintu cyo gukemura cya MBS kiri hagati ya 94 na 9.5, cyegereye ibipimo bya solubility ya PVC. Kubwibyo, ifite guhuza neza na PVC. Ikintu kinini kiranga nuko nyuma yo kongeramo PVC, irashobora gukorwa mubicuruzwa biboneye. Mubisanzwe, kongeramo ibice 10-17 muri PVC birashobora kongera imbaraga zingaruka inshuro 6-15. Ariko, iyo umubare wa MBS wongeyeho urenze ibice 30, imbaraga zingaruka za PVC ziragabanuka. MBS ubwayo ifite imikorere myiza, gukorera mu mucyo, no kohereza hejuru ya 90%. Mugihe utezimbere imikorere yingaruka, ntigira ingaruka nke kubindi bintu bya resin, nkimbaraga zingana no kurambura kuruhuka. MBS irazimvye kandi ikoreshwa kenshi hamwe nizindi mpinduka zoguhindura nka EAV, CPE, SBS, nibindi. MBS ifite ubushyuhe buke nubushyuhe bwikirere, bigatuma bidakwiriye gukoreshwa igihe kirekire hanze. Mubisanzwe ntabwo ikoreshwa nkimpinduka zingaruka mugukora urugi rwa plastike na profili yidirishya.

(4) SBS

SBS ni ternary block copolymer ya styrene, butadiene, na styrene, izwi kandi nka thermoplastique styrene butadiene rubber. Nibintu bya termoplastique elastomers kandi imiterere yabyo irashobora kugabanywamo ubwoko bubiri: inyenyeri ifite umurongo. Ikigereranyo cya styrene na butadiene muri SBS ni 30/70, 40/60, 28/72, na 48/52. Ahanini ikoreshwa nkimpinduka zingaruka kuri HDPE, PP, na PS, hamwe na dosiye yibice 5-15. Igikorwa nyamukuru cya SBS ni ugutezimbere ubushyuhe bwayo buke. SBS ifite ibihe bibi byo guhangana nikirere kandi ntibikwiriye gukoreshwa igihe kirekire cyo gukoresha hanze.

(5) ABS

ABS ni ternary copolymer ya styrene (40% -50%), butadiene (25% -30%), na acrylonitrile (25% -30%), ikoreshwa cyane nka plastiki yubuhanga kandi ikoreshwa no guhindura ingaruka za PVC, hamwe na bike -ingaruka zo guhindura ingaruka. Iyo umubare wa ABS wongeyeho ugeze mubice 50, imbaraga zingaruka za PVC zirashobora kuba zingana niza ABS yera. Umubare wa ABS wongeyeho ni ibice 5-20. ABS ifite imiterere mibi yikirere kandi ntabwo ikwiriye gukoreshwa igihe kirekire hanze yibicuruzwa. Mubisanzwe ntabwo ikoreshwa nkimpinduka zingaruka mugukora urugi rwa plastike na profili yidirishya.

(6) EVA

EVA ni kopolymer ya Ethylene na vinyl acetate, kandi kwinjiza vinyl acetate bihindura kristu ya polyethylene. Ibiri muri vinyl acetate biratandukanye cyane, kandi indangantego ya EVA na PVC iratandukanye, kuburyo bigoye kubona ibicuruzwa biboneye. Kubwibyo, EVA ikoreshwa kenshi hamwe nizindi ngaruka zidashobora kwihanganira. Umubare wa EVA wongeyeho ntabwo uri munsi yibice 10.
