1. Umubare wuzuye
Umubare wijimye ugereranya uburemere bwa molekuline yuburemere kandi nicyo kintu nyamukuru kiranga kumenya ubwoko bwa resin. Imiterere nimikoreshereze ya resin biratandukanye bitewe nubwiza. Mugihe urugero rwa polymerisation ya PVC resin yiyongera, imiterere yubukanishi nkimbaraga zingutu, imbaraga zingaruka, imbaraga zavunitse, hamwe no kuramba mugihe cyo kuruhuka, mugihe imbaraga zumusaruro zigabanuka. Ibisubizo byubushakashatsi byerekana ko uko urwego rwa polymerisiyasi yimfashanyo itunganya PVC rwiyongera, imitungo yibanze ya resin iratera imbere, mugihe imikorere yo gutunganya nimyitwarire ya rheologiya yangirika. Birashobora kugaragara ko gukwirakwiza uburemere bwa molekuline ya PVC resin bifitanye isano ya hafi no gutunganya plastike no gukora ibicuruzwa.
2. Kubara ibice byanduye (utudomo twumukara numuhondo)
Ibice byanduye ni kimwe mubipimo byingenzi byo gusuzuma PVC resin. Impamvu nyamukuru zigira ingaruka kuri iki cyerekezo ni: icya mbere, ibikoresho bisigaye kurukuta rutwikiriye isafuriya ya polymerisation ntabwo byogejwe neza kandi ibikoresho bibisi byandujwe n’umwanda; icya kabiri, imyenda ya mashini ivanze numwanda nigikorwa kidakwiye kizana umwanda; Mubikorwa byo gutunganya plastike, niba hari uduce twinshi twanduye, bizagira ingaruka mbi kumikorere no gukoresha ibicuruzwa bya PVC byakozwe. Kurugero, mugutunganya no gushiraho imyirondoro, hariho umwanda mwinshi nuduce, bishobora gutera ibibara kugaragara hejuru yumwirondoro, bityo bikagabanya ingaruka zigaragara kubicuruzwa. Byongeye kandi, bitewe no kudahindura plastike yibice byanduye cyangwa imbaraga nke nubwo plastisike, imiterere yibicuruzwa iragabanuka.
3. Ibirunga (harimo n'amazi)
Iki kimenyetso cyerekana gutakaza ibiro bya resin nyuma yo gushyuha ku bushyuhe runaka. Ibiri hasi yibintu bihindagurika birashobora kubyara byoroshye amashanyarazi ahamye, ntabwo bifasha ibikorwa byo kugaburira mugihe cyo gutunganya no kubumba; Niba ibintu bihindagurika ari byinshi cyane, ibisigara bikunda guhuzagurika no gutembera nabi, kandi ibibyimba bitangwa byoroshye mugihe cyo kubumba no kubitunganya, bigira ingaruka mbi kumiterere yibicuruzwa.
4. Ubucucike bugaragara
Ubucucike bugaragara nuburemere kuri buri gice cyifu ya PVC resin yifu idahwitse. Bifitanye isano nuduce duto twa morphologie, impuzandengo yikigereranyo, nubunini bwagabanijwe bwa resin. Ubucucike bugaragara, ubwinshi, kwinjiza vuba plastike, no gutunganya byoroshye. Ibinyuranye, ubunini buringaniye buringaniye nubunini buke biganisha ku kwinjiza ibikoresho bifasha gutunganya PVC. Kugirango habeho ibicuruzwa bikomeye, uburemere bwa molekuline ntibisabwa cyane, kandi plasitike ntishobora kongerwaho mugihe cyo kuyitunganya. Kubwibyo, ububobere bwibice bya resin birasabwa kuba hasi, ariko haribisabwa kugirango amazi yumye yumye, bityo rero ubucucike bugaragara bwibisigarira buri hejuru.
5. Kwinjiza plastike
Ingano yo kwinjiza ibikoresho bifasha gutunganya PVC byerekana urugero rwa pore imbere mubice bya resin, hamwe nigipimo kinini cyo kwinjiza amavuta hamwe nubunini bunini. Ibisigarira byinjiza plasitike vuba kandi bifite imikorere myiza yo gutunganya. Kubishushanyo mbonera (nka profili), nubwo ibisabwa kugirango resin porosity itaba hejuru cyane, imyenge iri imbere mubice bigira ingaruka nziza ya adsorption mugushyiramo inyongeramusaruro mugihe cyo gutunganya, biteza imbere imikorere yinyongera.
6. Kwera
Umweru ugaragaza isura n'amabara ya resin, kimwe no kwangirika guterwa no kutagira ubushyuhe bukabije bwumuriro cyangwa igihe kinini cyo kugumana, bigatuma igabanuka ryera cyane. Urwego rwera rufite ingaruka zikomeye kubusaza bwibiti nibicuruzwa.
7. Ibirimo vinyl chloride isigaye
Ibisigisigi bya VCM bivuga igice cyibisigazwa bitigeze byamamazwa cyangwa ngo bishonge muri monomer polyethylene, kandi ubushobozi bwa adsorption buratandukanye bitewe nubwoko bwa resin. Mubyukuri ibintu bisigaye bya VCM, ibintu byingenzi birimo ubushyuhe buke bwo hejuru bwumunara wambuwe, itandukaniro ryumuvuduko ukabije muminara, hamwe na morfologiya mbi ya resin, ibyo byose bishobora kugira ingaruka kuri desorption ya VCM, nikimenyetso cyo gupima urwego rwisuku ya resin. Kubicuruzwa bidasanzwe, nka tin foil bigoye gukoporora imifuka yububiko bwa farumasi yubuvuzi, ibisigisigi bya VCM bisigaye ntibishobora kuba bisanzwe (munsi ya 5PPM).
8. Guhagarara neza
Niba amazi arimo muri monomer ari menshi cyane, azabyara aside, yonone ibikoresho, akora sisitemu ya polymerisiyonike, kandi amaherezo bizagira ingaruka kumyuka yibicuruzwa. Niba hydrogène chloride cyangwa chlorine yubusa ihari muri monomer, bizagira ingaruka mbi kuri reaction ya polymerisation. Hydrogen chloride ikunda kwibumbira mumazi, igabanya agaciro ka pH ya sisitemu ya polymerisation kandi ikagira ingaruka kumikorere ya polymerisation. Byongeye kandi, ibintu byinshi bya acetylene muri monomer yibicuruzwa bigira ingaruka kumyuka yubushyuhe bwa PVC bitewe ningaruka ziterwa na acetaldehyde nicyuma, bigira ingaruka kumikorere yibicuruzwa.
9. Shungura ibisigisigi
Igisigara cya sikeri kigaragaza urugero rwubunini buke buke bwa resin, kandi ibintu byingenzi bigira uruhare runini ni urugero rwo gutatanya muri formulaire ya polymerisation n'ingaruka zitera. Niba ibice bya resin ari bibi cyane cyangwa byiza cyane, bizagira ingaruka kumurongo wa resin kandi bigira ingaruka no gutunganya ibicuruzwa nyuma.
10. “Ijisho ry'Amafi”
“Ijisho ry'amafi”, rizwi kandi nka kristu ya kirisiti, ryerekeza ku bice bya resin mu mucyo bitigeze bishyirwa mu buryo busanzwe bwo gutunganya ibintu bya termoplastique. Ingaruka mubikorwa nyabyo. Impamvu nyamukuru y "ijisho ryamafi" nuko iyo ibirimo ibintu bitetse cyane muri monomer ari byinshi, bishonga polymer imbere mubice mugihe cya polymerisiyonike, bigabanya ubukana, bigatuma ibice bikomera, kandi bigahinduka "ifi yigihe gito ijisho ”mugihe cyo gutunganya plastike. Uwatangije akwirakwizwa mu buryo butaringaniye mumavuta ya monomer. Muri sisitemu ya polymerisiyasi hamwe no guhererekanya ubushyuhe butaringaniye, gukora resin ifite uburemere buke bwa molekile, cyangwa umwanda wa reaction mugihe cyo kugaburira, ibisigazwa bisigara, cyangwa gufatira cyane ibikoresho bya reaktor byose bishobora gutera "fisheye". Imiterere y "amaso y amafi" igira ingaruka itaziguye ubwiza bwibicuruzwa bya PVC, kandi mugutunganya nyuma, bizagira ingaruka kumiterere yibicuruzwa. Bizagabanya kandi imiterere yubukanishi nkimbaraga zingana no kurambura ibicuruzwa, bishobora kuganisha byoroshye gutobora firime ya pulasitike cyangwa amabati, cyane cyane ibicuruzwa byabigenewe, bizagira ingaruka kumashanyarazi. Nibimwe mubimenyetso byingenzi mugukora resin no gutunganya plastike.
