Liquid Barium Zinc PVC Stabilizersndeakasarudzika ekuwedzera anoshandiswa mu polyvinyl chloride (PVC) kugadzirisa kusimudzira kupisa uye kugadzikana kwechiedza, kudzivirira kudzikira panguva yekugadzira uye kuwedzera hupenyu hwezvinhu. Heino tsananguro yakadzama yekuumbwa kwavo, mashandisirwo, zvekutonga, uye mafambiro emusika:
Kuumbwa uye Mechanism
Aya ma stabilizer anowanzo sanganisira barium munyu (semuenzaniso, alkylphenol barium kana 2-ethylhexanoate barium) uye zinc munyu (semuenzaniso, 2-ethylhexanoate zinc), yakasanganiswa nesynergistic components se phosphites (semuenzaniso, tris(nonylphenyl) phosphites) yemafuta echelation, mineral uye solvent. Iyo barium inopa nguva pfupi yekudzivirira kupisa, nepo zinc inopa kugadzikana kwenguva refu. Iyo fomu yemvura inovimbisa kusanganisa yunifomu muPVC magadzirirwo. Mazuva ano maumbirwo anosanganisirawo polyether silicone phosphate esters kuvandudza lubricity uye pachena, kuderedza kunyura kwemvura panguva yekutonhora.
Makomborero Anokosha
Non-Toxicity: Yemahara yesimbi inorema senge cadmium, inoenderana nekudya-yekuonana uye yekurapa-giredhi zviyero (semuenzaniso, FDA-akatenderwa mamakisi mune mamwe magadzirirwo) .
Kugadzirisa Kubudirira: Liquid state inovimbisa kupararira kuri nyore mumakomisheni akapfava ePVC (semuenzaniso, mafirimu, waya), kuderedza nguva yekugadzirisa uye kushandiswa kwesimba.
Mutengo-Kubudirira: Kukwikwidza ne organic tin stabilizers uchidzivirira kunetseka kwehupfu.
Synergistic Migumisiro: Kana yakabatanidzwa ne calcium-zinc stabilizers, inotaura nezve "tonguing" nyaya mune yakaoma PVC extrusion nekuenzanisa lubricity uye kugadzikana kwekupisa.
Applications
Yakapfava PVC Zvigadzirwa: Inoshandiswa zvakanyanya mumafirimu anochinjika, tambo, matehwe ekugadzira, uye zvigadzirwa zvekurapa nekuda kwekusava nehuturu uye kujeka kwekuchengeta.
PVC yakaoma: Mukubatana necalcium-zinc stabilizers, ivo vanovandudza processability mumafirimu uye profiles, kuderedza "tonguing" (zvinhu kutsvedza panguva extrusion).
Specialty Applications: Yakakwira-pachena magadzirirwo ekurongedza uye UV-inodzivirira zvigadzirwa kana zvakapetwa ne antioxidants senge 2,6-di-tert-butyl-p-cresol.
Regulatory uye Environmental Kufunga
SVITSA Kuteerera: Barium makomisheni inodzorwa pasi peREACH, ine zvirambidzo pane soluble barium (semuenzaniso, ≤1000 ppm mune zvigadzirwa zvevatengi). Yakawanda yemvura barium zinc stabilizers inosangana nemiganhu iyi nekuda kwekuderera kunyungudika.
Dzimwe nzira: Calcium-zinc stabilizers iri kuwana traction nekuda kwekuomarara kwemitemo yezvakatipoteredza, kunyanya muEurope. Zvisinei, barium zinc stabilizers inoramba ichisarudzwa mukushanda kwepamusoro-kupisa (semuenzaniso, zvikamu zvemotokari) apo calcium-zinc chete inogona kunge isina kukwana.
Performance uye Technical Data
Thermal Kugadzikana: Static heat tests inoratidza kugadzikana kwakawedzerwa (eg, 61.2 maminetsi pa 180 ° C nokuda kwekuumbwa ne hydrotalcite co-stabilizers) . Dynamic processing (semuenzaniso, twin-screw extrusion) inobatsira kubva kune yavo yekuzora zvivakwa, kuderedza kushatisa kweshear.
Transparency: Magadzirirwo epamberi ane polyether silicone esters anowana yakakwira optical kujeka (≥90% transmittance), ichiita kuti ive yakakodzera kurongedza mafirimu.
Migration Resistance: Magadzirirwo akagadzirwa zvakanaka anoratidza kutama kwakaderera, kwakakosha kune zvikumbiro senge chikafu kurongedza uko kunowedzera kutama kuri kunetseka.
Mazano Ekugadzirisa
Kugarisana: Dzivisa kushandiswa kwakanyanya kwe stearic acid lubricant, sezvavanogona kuita nemunyu we zinc, kukurumidza kuparara kwePVC. Sarudzaco-stabilizerskunge epoxidized soya mafuta ekusimudzira kuenderana.
Dosage: Chimiro chekushandiswa chinobva ku1.5-3 phr (zvikamu pazana resin) muPVC yakapfava uye 0.5-2 phr mukugadzirisa kwakasimba kana yakabatanidzwa ne calcium-zinc stabilizers.
Market Trends
Kukura Vatyairi: Iko kudiwa kweasina-chepfu stabilizers muAsia-Pacific neNorth America iri kusundira hutsva mu barium zinc maumbirwo. Semuenzaniso, indasitiri yeChina yePVC inowedzera kutora mvura barium zinc stabilizer yekugadzira waya/tambo.
Matambudziko: Kukwira kwe calcium-zinc stabilizers (inofungidzirwa CAGR ye5-7% muzvigadzirwa zveshangu uye zvikamu zvekuputira) inokonzera makwikwi, asi barium zinc inochengetedza niche yayo mukushanda kwepamusoro-kushanda.
Liquid Barium Zinc PVC Stabilizers inopa chiyero chemutengo-unoshanda, kugadzikana kwekupisa, uye kutevedza kwemitemo, zvichiita kuti zvive zvakakosha mune zvakapfava uye semi-yakaomarara PVC zvigadzirwa. Nepo kudzvinyirirwa kwezvakatipoteredza kuchifambisa shanduko yakananga kune dzimwe nzira dzecalcium-zinc, zvimiro zvavo zvakasarudzika zvinogonesa kuenderera mberi kwakakosha mumisika ine hunyanzvi. MaFormulators anofanirwa kudzikamisa mashandiro ekuita nemaitiro emitemo kuti vawedzere mabhenefiti avo.
