1 Intangiriro
Ibikoresho byubaka imiti nubwoko bushya bwa kane bwibikoresho byubwubatsi bugezweho nyuma yicyuma, ibiti na sima, cyane cyane harimo imiyoboro ya pulasitike, inzugi za pulasitike n'amadirishya, kubaka ibikoresho bitarimo amazi, ibikoresho byo gushushanya, nibindi. Ibikoresho nyamukuru ni polyvinyl chloride (PVC).
PVC ikoreshwa cyane nkibikoresho byubwubatsi kandi imyirondoro yayo ya pulasitike ikoreshwa cyane mumiryango yo hanze no hanze no mumadirishya yinyubako ninganda zishushanya, hamwe nibintu byiza cyane nko kubika ubushyuhe, gufunga, kuzigama ingufu, kubika amajwi hamwe nigiciro giciriritse, nibindi. Kuva kumenyekanisha, ibicuruzwa byatejwe imbere byihuse.
Nyamara, imyirondoro ya PVC nayo ifite ibibi bimwe, nkubushyuhe buke, imbaraga nkeya, ningorane zo gutunganya.Kubwibyo, imiterere yingaruka hamwe na plastike ya PVC igomba kunozwa.Ongeraho abahindura muri PVC birashobora kunoza neza ubukana bwayo, ariko abahindura bagomba kugira ibintu bikurikira: Ubushyuhe bwo hasi bwikirahure;igice gihujwe na PVC resin;ihuye n'ubukonje bwa PVC;nta ngaruka zikomeye kumiterere igaragara na mashini ya PVC;ikirere cyiza nikirere cyiza cyo kurekura kwaguka.
Impinduka zikoreshwa cyane muri PVC ni chlorine polyethylene (CPE), polyacrylates (ACR), methyl methacrylate-butadiene-styrene terpolymer (MBS), acrylonitrile-butadiene-styrene copolymer (ABS), Ethylene vinyl acetate copolymer (EVA) (EPR), n'ibindi
Isosiyete yacu yateje imbere kandi ikora ibyingenzi-shell PVC modifier JCS-817.Iyi modifier ifite ingaruka nziza mugutezimbere plastike nimbaraga za PVC.
2 Basabwe
Ingano yo guhindura JCS-817 ni 6% kubice 100 byuburemere bwa PVC resin.
3 Kugereranya ikizamini cyo gukora hagati yabahinduye batandukanye niyi modifier JCS-817
1. Tegura ibikoresho by'ibizamini bya PVC ukurikije formula iri mu mbonerahamwe ya 1
Imbonerahamwe 1
| Izina | Ibice kuburemere |
| 4201 | 7 |
| 660 | 2 |
| PV218 | 3 |
| AC-6A | 3 |
| Dioxyde ya Titanium | 40 |
| PVC (S-1000) | 1000 |
| Amabati meza | 20 |
| Kalisiyumu Carbone | 50 |
2. Kugereranya ikigereranyo cyingaruka zingaruka: Guteranya ibyavuzwe haruguru hanyuma ukavanga ibice hamwe na 6% byuburemere bwa PVC hamwe nabahindura PVC zitandukanye.
Ibikoresho bya mashini byapimwe nurusyo rufunguye rufunguye, urusaku ruringaniye, gukora icyitegererezo, hamwe nimashini igerageza isi yose hamwe nipimisha ryoroshye ryibiti nkuko bigaragara mumbonerahamwe 2.
Imbonerahamwe 2
| Ingingo | Uburyo bwo kugerageza | Imiterere yubushakashatsi | Igice | Ibipimo bya tekiniki (JCS-817 6interuro) | Ibipimo bya tekiniki (CPE 6phr) | Ibipimo bya tekiniki (Kugereranya icyitegererezo ACR 6phr) |
| Ingaruka (23 ℃) | GB / T 1043 | 1A | KJ / mm2 | 9.6 | 8.4 | 9.0 |
| Ingaruka (-20 ℃) | GB / T 1043 | 1A | KJ / mm2 | 3.4 | 3.0 | Nta na kimwe |
Duhereye ku makuru ari mu mbonerahamwe ya 2, dushobora kwanzura ko imbaraga zingaruka za JCS-817 muri PVC ziruta izo CPE na ACR
3. Kugereranya ikigereranyo cyimiterere ya rheologiya: Komatanya ibyavuzwe haruguru hanyuma wongereho 3% yuburemere bwa PVC kumurongo hamwe nabahindura PVC zitandukanye hanyuma ukavanga.
Ibikoresho bya pulasitiki byapimwe na Harometero rheometero bigaragara mu mbonerahamwe ya 3.
Imbonerahamwe 3
| Oya. | Gukoresha igihe (S) | Impagarike yuzuye (M [Nm]) | Umuvuduko wo kuzunguruka (rpm) | Ubushyuhe bw'ikizamini (℃) |
| JCS-817 | 55 | 15.2 | 40 | 185 |
| CPE | 70 | 10.3 | 40 | 185 |
| ACR | 80 | 19.5 | 40 | 185 |
Kuva ku mbonerahamwe ya 2, igihe cya plastike ya JCS-817 muri PVC ntikiri munsi ya CPE na ACR, ni ukuvuga JCS-817 bizavamo uburyo bwo gutunganya PVC.
4 Umwanzuro
Ingaruka zingaruka hamwe na plastike yumutungo wiki gicuruzwa JCS-817 muri PVC iruta CPE na ACR nyuma yo kugenzura ibizamini.
