Zvigadzikiso zveLiquid Barium Zinc PVCzvinhu zvinoshandiswa pakugadzira polyvinyl chloride (PVC) kuti zviwedzere kugadzikana kwekupisa nechiedza, kudzivirira kuora panguva yekugadzira uye kuwedzera hupenyu hwechinhu chacho. Heino kupatsanurwa kwakadzama kwemuumbirwo wazvo, mashandisirwo azvo, mitemo, uye mafambiro emusika:
Kuumbwa uye Maitiro
Izvi zvinosimbisa muviri zvinowanzo sanganisira barium salts (semuenzaniso, alkylphenol barium kana 2-ethylhexanoate barium) uye zinc salts (semuenzaniso, 2-ethylhexanoate zinc), pamwe chete nezvinhu zvinoshanda pamwe chete zvakaita sephosphites (semuenzaniso, tris(nonylphenyl) phosphite) yechelation uye solvents (semuenzaniso, mineral oils) yekupararira. Barium inopa dziviriro yekupisa kwenguva pfupi, nepo zinc ichipa kugadzikana kwenguva refu. Chimiro chemvura chinoita kuti kusanganiswa kwakafanana muPVC formulations. Mafomu matsva anosanganisirawo polyether silicone phosphate esters kuti ivandudze lubricity uye kujeka, zvichideredza kunwa kwemvura panguva yekutonhora.
Zvakanakira Zvikuru
Haisi Chepfu: Hazvina simbi dzinorema dzakadai se cadmium, zvinotevedzera mitemo yekubata chikafu uye yekurapa (semuenzaniso, mamakisi anotenderwa neFDA mune mamwe mafomura).
Kubudirira Kwekugadzirisa: Mamiriro emvura anoita kuti zvive nyore kupararira mumakemikari ePVC akapfava (semuenzaniso, mafirimu, waya), zvichideredza nguva yekugadzira uye kushandiswa kwesimba.
Kushanda Nemutengo Wakanaka: Inokwikwidzana ne organic tin stabilizers uku ichidzivirira kunetseka nezve chepfu.
Mhedzisiro yekubatana: Kana zvikasanganiswa nezvinodzivirira calcium-zinc, zvinogadzirisa matambudziko e "kurunga" muPVC extrusion yakasimba nekuenzanisa mafuta uye kugadzikana kwekupisa.
Mashandisirwo
Zvigadzirwa zvePVC zvakapfava: Inoshandiswa zvakanyanya mumafirimu anochinjika, tambo, dehwe rekugadzira, uye zvishandiso zvekurapa nekuda kwekusakuvadza uye kuchengetedza kujeka kwayo.
PVC yakaoma: Pamwe chete nezvinosimbisa calcium-zinc, zvinovandudza kugona kushandiswa mumafirimu nemaprofile, zvichideredza "kutsvedza kwechinhu panguva yekubuda).
Zvikumbiro Zvehunyanzvi: Mafomula anoonekera zvakanyanya ekurongedza uye zvigadzirwa zvisingapindi UV kana zvakabatana nema antioxidants akaita se 2,6-di-tert-butyl-p-cresol.
Kufunga Nezvemitemo uye Zvezvakatipoteredza
Kutevedzera REACH: Makemikoro eBarium anodzorwa pasi peREACH, nemiganhu pabarium inonyungudika (semuenzaniso, ≤1000 ppm muzvigadzirwa zvevatengi). Mazhinji emvura anogadzirisa barium zinc anosangana nemiganho iyi nekuda kwekunyungudika kwakaderera.
Zvimwe zvinogona kuitwa: Zvinosimbisa calcium-zinc zviri kuwedzera kusimba nekuda kwemitemo yakaoma yezvakatipoteredza, kunyanya muEurope. Zvisinei, zvinosimbisa calcium-zinc zviri kuramba zvichinyanya kufarirwa mukushandiswa kwekupisa kwakanyanya (semuenzaniso, zvikamu zvemotokari) uko calcium-zinc yega ingave isina kukwana.
Ruzivo rweKushanda uye Ruzivo rweUnyanzvi
Kugadzikana kweThermal: Kuyedzwa kwekupisa kwakasimba kunoratidza kugadzikana kwenguva refu (semuenzaniso, maminetsi 61.2 pa180°C pamafomura ane hydrotalcite co-stabilizers). Kugadziriswa kwakasimba (semuenzaniso, twin-screw extrusion) kunobatsira kubva muhunhu hwavo hwekuzora, zvichideredza kuora kweganda.
Kujeka: Mafomula epamusoro ane polyether silicone esters anowana kujeka kwakanyanya kwemaziso (≥90% transmittance), zvichiita kuti akwanise kurongedza mafirimu.
Kuramba Kutama: Zvigadziriso zvakagadzirwa zvakanaka zvinoratidza kufamba kushoma, zvakakosha pakushandisa senge kurongedza chikafu uko kufamba kwekuwedzera kuri dambudziko.
Mazano Ekugadzirisa
Kuenderana: Dzivisa kushandisa mafuta e stearic acid zvakanyanya, sezvo anogona kusangana ne zinc salts, zvichiita kuti PVC iparare nekukurumidza.zvinosimbisa muviri pamwe chetesemafuta e soya anogadziriswa kuti awedzere kushanda zvakanaka.
Chipimo chemushonga: Mashandisirwo akajairika anotangira pa1.5–3 phr (zvikamu pazana resin) muPVC yakapfava uye 0.5–2 phr mumafomura akaomarara kana akabatanidzwa necalcium-zinc stabilizers.
Maitiro Emusika
Zvinokurudzira Kukura: Kudiwa kwezvinodzivirira zvisina chepfu muAsia-Pacific neNorth America kuri kukurudzira hunyanzvi mukugadzira barium zinc. Semuenzaniso, indasitiri yePVC muChina iri kuramba ichishandisa zvidzivirira zve liquid barium zinc zvekugadzira waya/tambo.
Matambudziko: Kukwira kwecalcium-zinc stabilizers (CAGR inofungidzirwa ye5–7% muzvikamu zveshangu uye zvekurongedza) kunokwikwidza, asi barium zinc inoramba iine chinzvimbo chayo mukushandiswa kwepamusoro-soro.
Zvigadzikiso zveLiquid Barium Zinc PVC zvinopa mwero wekushanda zvakanaka kwemutengo, kugadzikana kwekupisa, uye kutevedzera mitemo, zvichiita kuti zvive zvakakosha muzvigadzirwa zvePVC zvakapfava uye zvisina kuomarara. Kunyange zvazvo kumanikidzwa kwezvakatipoteredza kuchitungamira kune dzimwe nzira dzecalcium-zinc, hunhu hwazvo hwakasiyana hunovimbisa kuramba kwakakosha mumisika yakasarudzika. Vagadziri vemagadzirirwo vanofanirwa kuyera zvinodiwa zvekushanda nemirairo yemitemo kuti vawedzere mabhenefiti avo.
