Isesengura ryibikoresho byingenzi bya PVC byoroshye

Ibendera rya PVC ryoroshye, ibikoresho byerekana ibimenyetso bikoreshwa cyane mukwamamaza, kwerekana ibyabaye, no gushushanya, bifite ibyiza byingenzi byo guhinduka neza, kuramba, no kugaragara neza. Urufunguzo rwo kugera kuri iyo mitungo ruri mu bikoresho bikora, cyane cyane bigizwe na polivinyl chloride (PVC) kandi bigakorwa hifashishijwe uburyo bwo gutunganya ibintu. Ibikurikira birambuye ibintu byingenzi biranga ibintu bya PVC byoroshye byerekana ibintu bitatu: ibigize ibintu, ibintu bikora, hamwe nubuhanga bwo gutezimbere tekinike.

1. Ibikoresho by'ibanze: Polyvinyl Chloride (PVC) Resin

Imiterere yingenzi ya banneri ya PVC yoroheje igizwe na resin ya polyvinyl chloride (PVC). PVC ni polymer ya termoplastique ikorwa na polymerisation ya vinyl chloride monomer (VCM). Urunigi rwarwo rurimo karubone ihamye - ya chlorine, itanga imiti irwanya imiti nimbaraga za mashini. Mubisobanuro bya banneri, PVC resin, nkibikoresho fatizo, itanga ubufasha bwumubiri - byerekana neza ko banneri irambuye iyo ifunguye. Urwego ruciriritse rwimikorere ya molekulari nayo irayemerera guhuza na curvature zimwe (urugero, inkingi ya silindrike cyangwa igorofa yerekanwe).

Birakwiye ko tumenya ko nubwo PVC isanzwe ikomeye ikomeye, nayo iracika intege kandi ntishobora guhuza byimazeyo ibisabwa byunvikana. Kubwibyo, inzira "guhindura plastike" ikoreshwa kenshi mubikorwa. Ibi bikubiyemo kongeramo urugero rukwiye rwa plasitike (nka phthalates hamwe namavuta ya soya ya epoxiside) kuri resin ya PVC. Ibi bihagarika zimwe mu mbaraga za van der Waals hagati yiminyururu ya molekile kandi bikagabanya ubushyuhe bwikirahure bwa polymer (Tg), bigahindura ibikoresho biva muburyo bukomeye. Iyi PVC yahinduwe igumana ruswa irwanya ruswa hamwe nuburyo bworoshye bwo gutunganya resin yumwimerere mugihe nayo igera kubintu bifatika nko kugoreka no guhindagurika.

II. Ibikoresho byubufasha bukora: Ibigize ibice byongera imikorere muri rusange

Kugirango turusheho kunoza uburambe bufatika bwa banneri, ibikoresho shingiro bya PVC akenshi byunganirwa nibintu bitandukanye byongeweho cyangwa ibikoresho byo hejuru, bikora ibintu byinshi - byubatswe.

Stabilisateur: Menya neza - Ikirindiro cyigihe

Kuberako banneri ikunze guhura nuburyo bwo hanze mugihe kinini (nko kwamamaza kumuhanda no kwerekana ibyapa), imirasire ya UV, ubushyuhe bwinshi, nubushuhe bwinshi birashobora gutera kwangirika kwiminyururu ya molekile ya PVC (urugero, dehydrochlorination), biganisha kumuhondo, ubukana, ndetse no gucika. Kubwibyo, stabilisateur yubushyuhe hamwe na stabilisateur yumucyo nibyingenzi muburyo bwo gukora. Gushyushya ubushyuhe, cyane cyane calcium - zinc stabilisateur zinc (ibidukikije byangiza ibidukikije) cyangwa ikayobora umunyu (gakondo), ifata HCl yakozwe mugihe cyo kubyitwaramo no kubuza kwangirika kwumunyururu. Stabilisateur yumucyo, harimo na UV ikurura (nka UV-531) hamwe nimbogamizi ya amine yumucyo (HALS), yongerera ubuzima ibikoresho byo hanze (mubisanzwe kugeza kumyaka 3-5) mugaragaza cyangwa gukurura urumuri rwa UV cyangwa guhagarika imiyoboro yubusa.

Kuvura Ubuso: Kuringaniza Icapiro nibintu birinda

Ibendera rya banner akenshi risaba inyandiko yanditse cyangwa ibishushanyo, bisaba ko wino nziza cyane hamwe no kuzuza amabara. Kugira ngo ibyo bishoboke, PVC substrate ikorerwa corona (kongera ingufu zubutaka binyuze mu gusohora ingufu za -) cyangwa igashyirwa hamwe n’amazi - ishingiye kuri wino - igereranya (nka acrylate copolymer coating) kugirango irangire neza kandi irinde gushira. Mubyongeyeho, banneri zimwe - zanyuma zerekana firime irinda PVC ibonerana (hafi 0.05-0.1mm yuburebure) hejuru. Iyi firime ntabwo itanga gusa ibishushanyo mbonera (birinda kwambara no kurira ku gishushanyo cyatewe no guterana amagambo buri munsi) ariko inongera imbaraga zo kurwanya amazi n’umukungugu, bigatuma ibera ahantu habi.

Kwuzuza Byuzuye: Kunoza Kuramba Kuramba

Kugira ngo wirinde kuvunika umunaniro uterwa no guhindagurika kenshi, amabendera amwe ya PVC arimo ibintu byuzuza ibintu byoroshye (nka polytetrafluoroethylene micropowder na nitrile reberi) cyangwa fibre ikomeza (nka fibre polyester staple fibre). Ibyo byuzuza, bikwirakwijwe muri materix ya PVC, birema "micro - imiterere ya buffer" ikwirakwiza umutwaro mu bice byo guhangayikishwa cyane, bityo bikongerera igihe cyo kubaho nyuma yo guhindagurika. .

III. Icyerekezo cyo gukoresha ibikoresho: Iterambere rihuriweho no kurengera ibidukikije n'imikorere

Hamwe no kwiyongera kw'isoko ryibikoresho birambye, banneri ya PVC igezweho igenda itera imbere igana uburozi buke, uburemere bworoshye, hamwe nibikorwa byinshi. Kurugero, phthalates, plasitiki gakondo, isimburwa na plasitiki yangiza ibidukikije nka citrate na epoxy fatty acide methyl esters kubera ingaruka z’ubuzima. Mu murenge wa stabilisateur, sisitemu ya calcium - zinc iratera imbere cyane, mugihe amata arimo ibyuma biremereye nka gurş na kadmium bigenda bikurwaho. Bamwe mubakora kandi bakoresha nanotehnologiya (nko kongeramo nano - titanium dioxide anticicrobial coatings) kugirango batange banneri ibintu byiyongera nko kwikorera - isuku hamwe na antibacterial, bikomeza kwagura imikoreshereze yabyo.

Muri make, ibikoresho byibanze bya PVC byoroshye banners bishingiye kuri polivinyl chloride resin yahinduwe, ikorwa byoroshye binyuze mumashanyarazi. Ibi byunganirwa na stabilisateur, ibice byo kuvura hejuru, hamwe no kuzuza imikorere, gukora sisitemu yuzuye yibintu ihuza imiterere, ihindagurika ryikirere, icapiro, hamwe nuburinzi. Ibiranga bituma bihinduka inzira nyamukuru yo kwamamaza ibyapa, kuringaniza ibikorwa nigiciro - gukora neza.
